AI Комикс: Jamie wanted nothing more than to be taller and stronger. Jamie was a 5ft skinny guy and was almost always ignored by girls. He was 20 and had not lost his virginity. To top it off he was a bit nerdy looking, but not that smart. At school he would get bullied and while at home he would take his anger out on the only person smaller and weaker than him, his little sister Jess. Jess was 4ft 10, tiny even for her age 18. She was a cute and polite brunette who could always be found reading. She loved reading so much in fact that she was reading text books far beyond her year group that Jamie hadn't even read yet. Jamie and Jess live in Belgium, where you go to Uni at 21. The two were not biological siblings, their mum adopted them both as she'd never married and wanted kids. In fact when Jamie got stuck on his homework, Jess would often try and help him. Jamie had been pulling his hair out over one particularly hard problem for hours. Jess wanting nothing more but to be Jamies friend and to help, came over and looked at it, within a couple minutes she had the answer and had written out all the workings. But Jamie, having a small ego, refused her help, scrunched up the workings and through them away. But that not being enough, in a petty rage he also found her text books she'd saved for and bought herself and destroyed them, in the hope that it would disuade her from helping him again in future. Some time later Jess and Jamie came into some inheritance when a relative they barely knew passed away. Jess saved the money while Jamie spent the full amount on some experimental growth drink he'd heard about. It was on an illegal site and cost his entire inheritance, but he wanted it badly. The advert read as follows: HIGHLY EXPERIMENTAL THIS DRUG WAS DEVELOPED IN NORTH KOREA FOR MILITARY PURPOSES. THE DRUG HAS ONLY BEEN TESTED ON MEN. DO NOT GIVE TO WOMEN. THE DRUG WAS DEEMED TOO EFFECTIVE AND BANNED, AS IT MADE THE USERS TOO POWERFUL AND HARD TO CONTROL. KNOWN SIDE EFFECTS: RAPID MUSCLE GROWTH, HEIGHT GROWTH, STRENGTH AND AGILITY. ADDED SIDE EFFECTS: HUGE COCK GROWTH, BALL GROWTH, SEMEN GROWTH AND PUBE GROWTH. ONLY TAKE ONCE. DRUG TAKES 14 DAYS TO WORK FULLY. Being shy about his purchase, Jamie ticked a box saying 'ship without label' and didn't mention anything to his family about this. Unfortunately for Jamie, the drink arrived a day when he wasn't there. Day 1 Jess was reading her book when she heard the door and signed for the mysterious parcel, "whats Jamie bought now?" Jess thought. The bottle was a stylish metal flask with a label on the side that just read "NOT FOR WOMEN". "Yeah right" she thought maybe he'd just bought a weird smoothie drink a YouTuber promoted. Jamie loved toxic guru videos. However, when she popped the lid it smelt AMAZING. She couldn't get over how good it smelt. She desperately wanted to put the lid back on knowing Jamie would be home soon, but she decided to give a little taste first. She had a sip, then a gulp, then another gulp, "WHAT AM I DOING" she thought, "JAMIE WILL KILL YOU". But she couldn't stop, it tasted too good. Before she knew what she'd done, she'd drunk the whole bottle. "Oh god, oh god, oh god" she thought after she'd finished. Thinking quickly she hid the bottle away at the bottom of the bin, maybe Jamie would just think it got lost in the mail. Almost immediately after she hidden the bottle she felt a burning sensation like she needed to pee, only her whole body was warm. She went to the toilet but nothing happened except she was getting warmer and warmer in her groin. She decided to feel it, her clit was rock hard and crazy sensitive. She began rubbing it gently, it felt insanely intense, she could feel sensation travelling up her spine. After just a minute of doing this, she came harder then she'd ever done in her life and for the first time ever, she squirted. "What on earth" she thought, "the drink couldn't have done that could it??" Calming down she decided to go back to the sofa and read her book, Jamie might be suspicious if he came home and she wasn't where she was always sat. Jamie came home 30minutes later, unlucky for Jess, Jamie asked immediately "Jess was there a parcel for me today?" "No, did you buy something?" Responded Jess casually. "Jess, don't be a brat. I got a notification on my phone saying you signed for my parcel?" "SHIT" Jess thought. Thinking on her feet she responded not looking up "oh err yeah a bottle might have arrived" Jamie getting more annoyed "where is it then shrimp, I paid a lot of money for that drink?" "Erm, well I may uh, I might have drunk it" said Jess meekly looking up. Jamie looked panic struck. "YOU DID WHAT?!" "I'm sorry, I just meant to smell it, but it smelt so good and... I kind of drunk it all" confessed Jess. "You fucking idiot, what have you done! Girls aren't meant to drink that stuff! you're buying me another one!" Said Jamie bright red with rage. "Yes of course! How much was it?" responded Jess. "My whole fucking inheritance!" Said Jamie now shouting. "WHAT?" Jess said thinking he must be exaggerating. "I spent my whole inheritance on that and you are buying me another" shouted Jamie. "Jamie, I'm so so sorry, but there is no way I'm spending that on a smoothie for you, you should have told me about it, what does it do? Cure cancer?" Jess was in shock, why would Jamie spend so much on a smoothie, was he joking? Then a thought hit her, "what do you mean girls aren't meant to drink this?" "It's a growth drug you dumb bitch! But it's only been tested on men, it probably wont even work on you" Jamie started punching a wall with rage. Jess ran up and tried to stop him causing damage, she grabbed his hand and when he turned they both saw something shocking, they were looking eye to eye. Day 2 Jamie woke up enraged. He'd spent the whole evening bullying his sister and forced her to buy another bottle for him. But even knowing another bottle would arrive in 14 days he'd slept awful. How could his sister of be as tall as him already? Will she get taller? Surely it wont be as effective on women. Jamie would soon get some answers. Not being able to sleep he went to get breakfast. Jamie was sat at the breakfast table waiting to be handed his toast when he heard his mum shriek "OH MY GOD JESS". Expecting to see his 5ft sister Jamie was in utter terror. Jess was now stood at a staggering 6ft. It was utterly bizarre to be looking up at tiny little Jess's face. She was the same hight as the door frame, her limbs were stick thin and poking through her pijama's. Jess was in tears and after explaining everything that happened, their mum was immediately taking Jess to the hospital. Jamie was brought with them. He sat next to Jess in the car and felt like a little child sat next to her. Jess had to wear Jamie's clothes, but him being 5ft and her being 6ft, the clothes were much too small for her tall frame. After waiting they were brought into the GP room, they waited for another minute then in walked the most stunning doctor Jamie had ever seen. Long blond hair, a tight skirt and even though they were hidden well, undeniably large breasts concealed under her shirt and lab coat. "The lab results are in" the doctor began to say in a warm friendly voice "and everything is fine. Jess will need to be brought back in for regular tests, but other than your height everything else is normal", then she looked over at Jamie, pushing her glasses up her nose "that was a very stupid thing you did buying that stuff online, you are lucky your sister wasn't harmed." Day 3 Jess woke up to the same sensation as the day before - that she HAD to masturbate - she slid her hands down to feel her clit when the first thing she noticed was that her pubes were getting way thicker. As she felt lower she felt her clit was huge, it felt like it might be an inch long. Rather than rubbing it as normal she pinched and rubbed it up and down, almost as if she was jerking off. The pleasure kept intensifying until again she came. She then got up and admired herself in the mirror, her body was perfection, she was a slim 6ft goodess, but she had noticed a few extra changes today. First she had indeed grown a thick set of pubes. Next her body was more muscular, no longer as twig like as before. She has a tight set of abs appearing and she could see the faint outline of a bicep on each arm, could her muscles be growing too? She could also see that her clit was poking though her bush, she was a little worried about this, she really didn't want that to keep growing. Day 4 Jamie woke up scared, his sister was definitely looking stronger yesterday, what will she look like today? When he came home from school yesterday he was relieved he was still able to wrestle the TV remote off of Jess, but it had be harder than he expected. Jamies jaw dropped when Jess walked into the kitchen, ducking her head under the doorway. She was wearing one of her old tops - not one of the new ones their mum had bought her - which let her abs poke out below. Her six pack was even thicker than yesterday and her biceps slightly larger. But that wasn't why he was shocked, her breasts were noticeably ... well ... large. Two perky water balloons were jiggling as she moved around the kitchen. Her mum walked in, clearly noticing what Jamie had noticed she said "oh honey, we are going to have to buy you a bra" "Oh yeah" Jess said cupping her new toys, they were slightly more than her hands could handle, "but better wait I can feel they are growing still" "fair enough honey" said their mum, "Jamie could you get me the pan off the top shelf". Jamie walked over tried to reach, he was almost there, straining on his tip toes when Jess came from behind saying "dont worry Mum, I've got it" Jamie felt Jess's hand on his shoulder while Jess's breasts rested gently on the back of his head - the closest he'd come to a woman's... well... anything before. Jess effortlessly picked up the pan and placed it on the counter. "I was getting it" Jamie said annoyed. "Your too short Jamie, you needed a stool" said Jess, patting Jamie gently on the head. Jamie thought he could see his sister smirk, she couldn't be enjoying humiliating him could she? Day 5 Today was Jess's first day back at school after everything had changed. She was terrified how everyone would react. Today when she'd woken up, she was slightly taller and slightly stronger, but her focus was on her growing clit. It was now at 3 inches long flaccid. She didn't want to think it, but it kind of looked like a penis. She would care more, but she was having the best orgasms of her life, she decided she'd wait until she saw the doctor again before saying anything. She reached for her tight white top again today, she saw Jamie looking yesterday and knew it drove him crazy. It fit again, only today it was much tighter, her breasts now filling the fabric and a long line of straining cleavage was running down the v-neck. She couldn't believe how perky they were for the size, when she cupped them they were far more than her hands could hold and much heavier than they looked. Despite their weight they sat beautifully on her cheast. She couldn't wait to go for breakfast, Jess knew her tits drove Jamie crazy yesterday, today they were almost twice as large. She loved humiliating Jamie now. As Jess walked in and pretended not to see Jamie staring at her. Despite not really feeling like it, she reached for a cereal box all the way on the highest shelf - just to demonstrate how easy it was for her. She then made a bowl of cereal twice the size of his and sat on the counter top, resting her new larger butt on the surface. Their mum walked in "Oh good Jess you are up, I was thinking today, I know I usually drive you both in, but I was actually thinking you could both walk in today?" "Are you sure Mum? I thought you said the Brockney Street wasn't safe?" Said Jess. Jamie was confused, this is something he'd wanted to do for years, but their mum wouldn't let him. He hated being dropped off by his mum and pleaded he would be sensible and take care of Jess if they walked, but she never let them. What had changed? "Well it isn't safe" said their mum, while she was busy getting her bits ready for work she continued "but I'm less worried now, just take care of your little brother OK?" Jess saw Jamie turn a bright red and shout "what do you mean little brother? I'm 2 years older than her?!" he walking up to their Mum past Jess. Jess noticed as he passed how funny and kind of cute he was when he was angry now. "Oh sorry Jamie" said there mum sweetly "I just meant you're the smaller sibling is all, your sister is so much bigger and stronger now, so she can protect both you if anything goes wrong, but I'm sure everything will be fine". Jess could not believe how amazing this feeling was. Her big bully of a brother, was now her little brother. She decided to rub this in a little more, by lifting up her arm, flexing her bicep and saying "dont worry mum, I'll protect us". Jess surprised herself with this a bit, she'd never flexed her new biceps before. Even with just a small flex the thing was thicker than Jamies leg, though his legs were very skinny. The bicep itself had noticeable vein running down it and was about the size of an apple. Jess saw Jamie clock the growth and leave the room visibly angry and humiliated. Day 6 Jamie had had the worst day ever yesterday. While no one knew Jess was his sister, he had heard everyone in the school talking about her. Everyone wanted to know who the new girl was, probably not realising she'd been there for years. Jess had tried to hold his hand on the way to school, he was certain she was humiliating him now. He hated walking with her. For most of the walk she walked ahead, her new longer legs meant that she walked faster effortlessly. However when it came to Brockney street a homeless man, visibly high, actually stopped Jamie and was getting very pushy. Jamie could see Jess walking on and panicking he cried out "JESS!". Jess turned, walked back, grabbed Jamie's out reached hand and walked them on. When the homeless man tried it on Jess she effortlessly pushed past him. The second Jamie felt safely away from the homeless man he pulled his hand away. Today he knew if he didn't want her help he would need to stay closer to her, where he was safe. He was about to walk in the kitchen when he heard a knock at the door. It was Jess, she was crouching to look through the doorframe, he tits were now so large they were spilling out under her shirt, large puffy nipples pressed so tight against the white fabric you could see the colour and outlying of them easily. "Sorry Jamie, you know your baggy white hoodie? I was hoping I could borrow it, this was my biggest shirt before" Said jess, intentionally choosing that moment to try and pull the shirt over her breasts, only for them to immediately slide back out from under, "only well, it doesnt quite fit me anymore." Jamie knew which on she meant, it was one he'd gotten for Christmas, but everything about it was too big and even the sleeves would dangle over his hands. He was thinking about saying no, but he didn't want to fight. He went to look for it while Jess walked into the room. "Did you hear?" Jess said "They've asked me to join the weightlifting team at school, which means I can use all the weights for free" "What are you weightlifting for?" Jamie said annoyed "you're already a freak of nature!" "I just want to test my new strength" Jess said flexing her biceps in front of him again. They were huge! In just one day it looks like they might have doubled. Yesterday they were big, but they were more skin on muscle, today they were thick protien cannons, with one almost cable sized vein running down each bicep. "I tried bicep curling for the first time. I'd never done it before so I'm not sure whats good. You used to go to the gym right? What did you used to curl?" Jamie knew full well that all he could curl was the 5kg, he'd managed 10kg but only for 1 rep, but he pretended not to remember. "Ahh well I lifted 30kg, which they said was good, but if I'm being honest I wasn't trying that hard" Jess said smiling, knowing full well that no one in the school could possibly come close to her strength, let alone her skinny 'little' brother. 30KG! This was half his weight! His little 18 year sister, who was 4.5ft a week ago could now lift half his weight with one arm! He found the jumper it was actually heavy for him to lift and way oversized for him, but trying to act calm and handed it to her. She pulled it over her head and as she did her breasts looked like they might almost escape from under the top. He watched as she struggled with the jumper, he could see already it wasn't going to fit her already. But he couldn't help take the opportunity to notice her abs had gotten thicker and more meaty too and 2 more had appeared at the bottom, partially obscured by a thick black pubes now poking out above her joggers. "Jesus Jess don't you shave?" said Jamie without thinking. Jess pulled the jumper off, giving up trying to fit into it. "Err well I actually I was going to tell you, I tried to shave last night with your trimmer and it well, the thing is my pubes are quite thick now and I think your little trimmer couldn't quite handle them, but don't worry, I've bought a new stronger one we can both use, should arrive next week." Jamie was desperate for his smoothie to arrive next week and end this humiliation. Day 7 Today Jess put on a new top her mum bought her, she still had her old top, only there was now no way should could wear it without her aolas poking out from under. The new top fit her snuggly and was much more comfortable and best of all it still had lots of cleavage. She was now a staggering 7ft, her legs would dangle off the end of the bed, she was desperate to go back to school, but today was the day she'd go back to see the Doctor for more tests. She was relieved because as she looked in the mirror, her clit was now most definitely a cock. She wasn't sure but she felt like it was a reasonably large one too. That morning their Mum - who had to go to work - agreed with Jess that Jamie should go with her to the doctor, then Jess could walk them both to school. Jamie was left out of all decision making these days. However Jamie's was a little excited because it meant they got to see the insanely hot doctor again. They were both sat in the Doctor's office in chairs side by side, Jess was looking down at her thick thighs next to Jamies twigs. Jess not thinking wrapped her index finger and her thumb around Jamies bicep and said "look Jamie I can wrap my hand around your whole arm." Jamie shook her off "leave me alone". "Oh dont be stroppy" said Jess. "I'm not being stroppy" said Jamie. "You can do mine?" Jess flexed her bicep in front of Jamie while Jamie tried his hardest not to look. "Why would I try that?" Jamie said annoyed. "Because I will hold your hand all the way to school today if you dont" said Jess in a humorless voice. Jamie knew she was serious and obliged. Seemingly knowing 1 hand wouldn't be enough he reached forward with both. Jamie wrapped his hands around her right arm, Jess could feel Jamie gently squeezing it with his fingers. Jess was shocked as she began to realise both Jamies hands wouldn't even have a chance wrapping around her flexed bicep. Curious Jess began to relax her arms to give Jamie a chance. To Jess's delight Jamie clearly could tell what was going on and began to go red when she did this. Even when Jess's bicep was fully relaxed and with both hands, he still could not fully grasp it. Jess was becoming more and more red by the second, except she could tell he wasn't angry anymore, it was to realisation of how much more powerful she was than him. Rubbing it in and taking pleasure in the moment Jess said "come on Jamie I'm not even tensing anymore", sounding almost sounding disappointed in him. Jess could see Jamie using all his force to get his fingers to touch, but there was almost an inch for him to go when the doctor walked in. "Hi Jamie, Hi J..." She paused looking at Jess, who was almost eye level with the 5ft 10" Doctor sat down. "Hey Doc" said Jess in a friendly voice. The Doctor looked shocked as she said "wow Jess, erm wow! You've grown... Would you err, stand up for me please Jess?" Jess obliged and even though he wasn't asked, Jamie did the same. Jess noticed that Jamie being 5ft barely came to the Doctor's chin, while Jess being over 7ft, meant Jamie barely came up to her tits. In fact, without even trying to humiliation Jamie, Jess would walk into him by mistake sometimes when she moved around the house, ocassionally not even noticing she'd knocked him over at all. The Doctor walked up to Jess and began examining Jess's biceps in curiosity. Jess noticed Jamie staring with extreme jealousy as the Doctor admired and stroked the thick cable like vine running down Jess's Bicep with her thumb. "This is all in one week?" she asked breathlessly arching her neck to look up at 7ft Jess. Jess nodded. As Jess felt the doctors hands on her bicep, she began to feel slightly aroused and notice her nipples begin to get hard. Jess knew it would be almost impossible for Jamie and the Doctor not to notice too. While she didn't care about Jamie, she was a little embarrassed when the Doctor saw them. For the first time in a week she blushed and said "err sorry". The doctor chuckled gently "not at all, it's cold in here, can I feel them?" "Errr, sure" said Jess, unsure what the Doctor meant. The Doctor cupped Jess's beasts gently and shook them, almost as if just to test they were really real. Jess was pretty sure this wasn't an official test. "Incredible" she whispered, then coughed almost as if to wake herself up from a dream. She then stepped back so that she could look up at Jess, pushing her glasses up her nose she asked "erm jess, I was doing research on the drug you drank and has there been err... anything else erm, well ... growing?" Jess looked down and saw Jamie looked completely confused by the question, then looked back up at the Doctors bright blue eyes and thought about the question. "oh yeah she said" and perhaps because she was now so big and so strong, but completely without thinking about Jamie being there she pulled her pants down "my clit has well ... gotten bigger". The Doctor and Jamie both went white as they stared at Jess's flaccid 5 inch meaty cock hung in front of them, complete with balls the size of cream eggs. Jess watched as Jamie stepped back, she was sure it was a big one now, but still unsure on how big, she'd never watched porn and was a virgin. Jess was the first to break the silence "I first just thought my clit was growing, but now I'm pretty sure its a penis, because every time I masturbate it cums", Jess said almost as if this were a normal conversation. "Yes Jess, its definitely a penis" responded the Doctor not looking up and almost sounding impressed, "you might want to warn people before pulling that out in future" she said looking at Jamie who was stood mouth wide open and now so white he looked like he might faint. "You said you can cum?" Said the Doctor now curious looking back at Jess. "Yes" said Jess politely. "Would you mind giving me a sample?" Before waiting for a response she turned her head to Jamie and a said "and Jamie, I will need one from you too". "What?" Said Jamie in a horrified voice. The Doctor turned to look at Jamie straight on, "Look in order to check your sister is healthy we need a sample form her, and if there are any issues it would be good to have someone to compare her sample to" she walked over and picked up 2 cups handing one to Jamie and one to Jess. Jess was confused when the cup was given to her "is this for the cum?" Jess asked. "Yes my love" said the Doctor smiling. "Is... there a bigger one" said Jess. The Doctors smile dropped and Jess thought she could see Jamies heart sink even further. She actually felt her cock twitch at the humiliation he must be feeling. She was pretty sure this cup was a lot more than he could fill, but not her. "Will 2 cups do?" asked the doctor, biting her lip a little eyes not looking away from the cock. >> Switching to Jamie's point of view. Jamie had a hard time producing a sample, he couldn't get his sister's flaccid 5 inch monster out of his mind. Despite this he was rock hard from the vision of the Doctor feeling his sisters bicep. He dreamed of that being his bicep. After a little while he'd managed to cum and walked out. Noticing his sister wasn't done he sat down and looked at the small puddle of cum at the bottom of the cup, on the side of the cup it had lines on it going up to half a pint. There's no way his sister could actually fill this he thought. As he thought about this he was in waited a minute, then 5, then 15. Then finally over an hour later, his sister walked out. What was she doing in there? He soon could guess. "No fucking way" he whispered as out walked his sister WITH the Doctor, except the Doctors hair was messed up, no longer in a perfect tight pony tail and her top was wide open so that you could see her bra and her huge cheast which was dripping in sweat. She was pulling her skirt down and looked like she was having trouble walking. How hard could had Jess fucked her? Then a thought occoured. While the doctor towered above him, she was nothing to Jess, Jess could probably lift the doctor with ease with those huge arms. He hadn't noticed before but he could see the bulge now in his sisters pants, stretching down the skin tight jeans. How did that thing belong to his sister? and had she actually just fucked the doctor? Had his 18 year old sister just lost her virginity before him? Suddenly he realised, his little sister, with that cock, if this had of happened already, this was just the beginning. "Oh hi Jamie" the doctor said politely and breathlessly putting her glasses back on "Thanks for waiting, your sister needed some ... errr... assistance". Then he noticed something else, in the Doctor's right hand were 4 filled cups stacked up, some had visibly overflowed with cum dripping down the outside. His little sister had filled 4 whole cups! Then to Jamies continued shock, another nurse walked out of the room pulling up her scrubs! The nurse walked over to the fountain, drank what must of been a liter of water then collapsed in to a chair near Jamie breathing heavily like she'd just run a marathon. It looked like his little sister had not only had sex, but a threesome! This can not be happening he thought. "Oh is that your sample Jamie! Well done" Jamie almost didn't want to hand it over, the cup had probably 10mls of cum in the bottom. He saw Jess strain her eyes to see if there was actually anything in it. The doctor placed it on the top of the pile and looked over at Jess as said heartedly "looks like we wont get these confused". Jamies heart sunk, for the love of GOD, he needed that smoothie. _ On the way to school Jamie had to listen to how incredible sex with the doctor was. "She just kept saying she'd never had a cock so big!" Jess said happily "and then she called in this other nurse to look and she was the same!" Jamie said nothing as Jess continued. "I cant believe I've never had sex before, it's amazing! She said she'd never cum so much before. have you had sex Jamie?" Jamies heart dropped, he was pretty sure she knew the answer. "You've not had sex have you? Does it bother you that I've had sex before you? It's OK if it does." Jamie said nothing as Jess kept talking. "Admit it Jamie, you were scared when you saw my cock". That was it for Jamie as he foolishly retorted "no I wasn't! Anyway how much can that horse cock of yours really grow, bet you can barely get it errect" Jess smiled, she'd clearly wanted Jamie to ask this. Jess clearly took pleasure in the answer "the Doctor wandered that too" Jess said slowly "she said when she measured it, that it was about 11 inches", for the rest of the day Jamie thought about nothing else. Day 8 Jamie was lying in bed, erect, with a measuring tape. He had the tape next to his 4 inch erect cock, and the tape stretched to 5 inches. Jess's flaccid size. He kept thinking about how thick her flaccid cock would look next to his erect one. He looked over at his wrist and thought it was probably thicker than that too. Then he pulled the tape out longer, slowly extending it to the supposedly fully erect 11 inches. His little sister's beast was almost 3 times his and closer to the length of his thigh than his cock. He stared at the tape against his cock, Jess was basically a god next to him. He shamefully came to the thought of his sister fucking the absolute shit out of the Doctor and nurse, then went to the bathroom to clean up. Jess was walking out as he walked up. As always she had the towel tightly wrapped around her tits, but towel which used to drap along the floor now couldn't even fully cover her cock, the tip of which was poking out below. Jess who was un aware - not that she cared - did not see Jamie walking around beneath her and just walked on to her bedroom. When Jamie entered the bathroom the small bin which had been emptied yesterday, was now filled to the top with thick black pubes. Clearly the new trimmer had arrived. Jamie went to pick it up the device - as it had been a while since he'd had a trim - to his shock it was much heaver and bigger than he'd expected. It took 2 hands just to hold it comfortably. Jamie noticed that the thing was so powerful it needed mains power to run. He couldn't help but imagine how easy it must be for his sister to use, this would be nothing for her giant hands and new strength to use. Jamie curious why Jess needed such a device placed it down and picked up a clump of her pubes. The clump was huge and thick, each pube resembled wires more than actually hair. He then tried to pull the clump apart, but couldnt. He pulled harder and harder but it barely budged, even with all his strength it was useless. Then it hit him, he could no longer even win a fight against Jess's pubes. Staring at the huge heavy clump of hair in his hands he was now sure there was not a single part of his sister her was stronger than. He picked up the trimmer again and slowly slid on the power switch and imidiately dropped it in terror, the thing was a practically a hedge trimmer! He was sure that if he was to use that on his cock, it would be more likely to cut his cock off then trim his pubes. He decided to leave it and buy his own smaller trimmer and hide it from his sister. Again he thought about how badly he needed that smoothie. _ Word at school had spread about his sisters 'package' too and that she was his sister. At first he enjoyed the attention until it was pretty clear they just wanted to meet Jess. Despite his sister being 2 years below him girls in his class were begging to be introduced. "Hey Jamie" said the insanely hot Emily from his school house, Emily had never once even looked at him before, "you're the brother of that Jess girl right?" Jamie couldn't believe Emily was even talking to him "err yeah I guess". "Well" Emily started, getting right to the point "would you mind inviting her to my house party tomorrow night, my parents are away, and well, you can come too I guess, but you have to bring Jess". Then after saying just that, she handed him a piece of paper with her address on it and the date and walked off. Day 9 Jess was again standing in front of her bedroom mirror wondering what to wear. Her head was now almost touching the cealing, her cock swinging 6 inches from her thick bush, which despite having been trimmed yesterday, was already starting to grow back thick and fast. Se wondered why Jamie had invited her along to this party tonight even though he seemed to hate her these days. She was thinking it was probably that slut Emily from his class. Only 2 days had passed since Jess's secret got out and Emily had approached her twice. Jess already had her hands on bigger prizes however, the gym teacher Alice had taken a special interest in her. Alice had had suspcions earlier as she'd seen the bulge through Jess's gym gear. Alice was a 30 year old smoking hottie who was always complaining about her shit ass lazy boyfriend. However, until yesterday, Alice hadn't mentioned how bad her boyfriend was in bed, now it's all she could talk about. "I just dont feel satisfied by him tbh", "he cant even get me pregnant" and "tbh - and I cant believe I'm saying this to a pupil, but I really just want to be fucked hard". Tomorrow she was going to give Alice what she wanted. She slid on the only jeans that fit, and with effort slid a white v-neck top over her huge tits and left to walk Jamie to the party. While on their way out their Mum stopped them "wait! Have a great time at the party and Jess look out for your li-big brother. Dont let anyone hurt him OK". "What are you saying Mum? I'm should be looking out for Jess?" Said Jamie, but even he knew that in reality, Jess really was watching over him. Jess just ignored Jamie "dont worry Mum I will keep him safe". On the way to the party they went to get booze. Jamie went first, but got rejected buying 20 light beers because they assumed his actualy valid 20 year old ID was fake. So Jess then went in and got served instantly, she came out carrying two 20 bottle beer crates of extra strong ales under each arm. "What are you doing?" protested Jamie "I can't drink all that?" "Relax" responded Jess, "I bought them and I hate that light shit. Anyway most of these are for me, you'll only need a couple". "Just because your big doesnt mean you can out drink me, I'm still a guy" said jamie clearly annoyed. Jess was ready for this though when she responded "I'm over 7ft Jamie and your 5ft. I barely see you when I'm walking round the house and I am willing to bet my cock is thicker than your arms now. I doubt you could even drink half as much as me". Jamie said nothing. When they arrived, Jess made sure everyone knew that she got served while little Jamie didn't. Jess watched as Jamie went to get a drink when Emily came over. Emily was looking better than Jess expected, she was wearing a bra-like top and jean shorts she hadn't notice before how great her tits looked, which were usually hidden under a school shirt. Things were a bit of a blur, but soon Jess and Emily were sat on a sofa making out and chatting amoungst a busy room full of people. Jess caught Jamie walking by and catching a glimpses of Emily - the hottest girl in his class - gently and knowingly resting her hand on Jess's cock bulge. Emily was getting Jess drink after drink, but Jess was barely feeling drunk. "You got anything stronger?" whispered Jess in Emily's ear. "Stronger? You've had 30 beers, you should be dead!" responded Emily getting up. She returned with a big bottle of whiskey just as Jamie walked over. Jamie had been quitely watching as her sister drank 30 of their 40 beers, Jamie had had 4 and was already wasted. "Give me some Emily" said Jamie drunkenly. "No way you are wasted" said Emily, but just as she said that he grabbed the bottle. Just before he chugged it, he wisely chose to pour out a small shot into a glass before downing it. This didn't help though, as he immediately threw up on Emily's carpet in front of everyone. "What the fuck Jamie!" cried Emily. "Aww dont get angry at him Emily, he's only small, this like a pint glass to him" she said picking up the small shot glass, looking straight at Emily and not even acknowledging him. Jamie clearly drunk and angry wanted to prove himself, "Shut up! I'm not a kid. I can drink it. I was just surprised by the taste. Give it to me again!" He went to grab the bottle, but Jess got to it first, she barely noticed him clinging to it as she pulled the bottle towards her with Jamie attached. Jamie let got before she could lift him up with it. 'Smart move Jamie' she thought as she sniffed the bottle, then to Jamie's and the room's surprise, she began to drink 70% whiskey straight from the bottle. Jess expected this to go badly, but she couldn't actually sit and watch Jamie drink and embarrass himself anymore. To her shock however, she really enjoyed the first gulp. Then the second. Then the third. Before she knew it, she was drinking the whole bottle to a cheering room. Everyone but Jamie was chanting "We like to drink with Jess, because Jess is our mate, and when we drink with Jess, she downs it all in 8! 8! 7! 6!" But before they could get to 5, the bottle was finished, she placed the bottle on the table as the room cheered in admiration. "Holy shit Jess! are you ok?!" shouted Emily. "Fuck yeah that was amazing!" said Jess enthusiatically and leant in to kiss her, Jess could feel her huge tongue filling Emily's mouth. Jess then felt Emily's hand slide up her top, Emily's small hands could barely grab Jess's huge aola's. Jess leant back and said with a small feminine burp "I'm deffinately feeling a little drunk now". Emily leant in and whispered in Jess's ear "how about we go up stairs and lie down". Jess was pretty happy with this idea and left Jamie sat on the sofa looking annoyed but also about to pass out. As they walked up Jess caught the envious eyes of all the men watching her. Which to her surprise, made her cock begin to twitch like crazy. She wondered if there was a signle man here that was bigger than her beast? Almost before the door was shut, Emily was already undressing, pulling off her shorts, revealing no underwear. Jess pulled off her top setting her tits free, she began to pull her jeans down when Emily stopped her to ask if she could do it. Jess nodded. Emily pulled off the top button, then the second, then the third. Emily could now see the base of the cock and whispered "holy shit", Jess closed her eyes as she felt Emilys tiny hands wrap around the base and with all her strength Emily began to pull the cock free from Jess's skin tight jeans. Jess felt her cock break free from its tight prison and instantly begin to swell. "I cant wrap my hand around it" said Emily almost in fear, Jess looked down at her still mostly flaccid cock to see that while Emily had mostly gotten her hands around it, should could indeed not fully grasp it. "Is that bad" she asked geniunely. "Its amazing" said Emily not looking up and leaning in to kiss it gently. Jess felt it fill with blood. Emily took turns stroking Jess's cock with both hands, cupping her balls and rubbing her own clit. Emily couldn't stop talking, "fuck its gets bigger?", "Its still fucking growing!" and "Jesus christ, it bigger than my head". Emily held her face against the now rock hard cock, it wasnt just bigger is was a safe few inches bigger. Jess pulled a condom out her pocket "I err stole this from Jamie, I doubt he will be needing it any time soon". Emily let out a loud "HA" then continued "you think that will fit this?" she said shaking Jess cock and smaking it against her head. "It wont? Can't they like - stretch a lot?" Jess asked. "Everything has limits Jess, but sure we can try" said Emily, pulling out the condom and attempting the place it on Jess's cock. Jess could see what Emily meant. It wasnt so much just the length, more the thickness. Emily as gently as posible managed to start getting the condom over the tip of Jess cock, but again Emily's tiny hands on her beast made her twitch. A small glob of precum slipped out, filling the condom instantly. "Did you cum?" asked Emily confused. "No that err just happens in the build up" said Jess slightly embarrsed, blushing again. "You mean to say that this is pre-cum" holding the small water ballon next to her head. Jess again nodded. Emily excited laid on the bed, Jess pulled off her jeans and walked over. She rested her cock on Emilys chest as Emily wrapped her legs around Jess's waist. Jess watched as Emily's two hands played curiously with her cock. Jess was comparing her 11 inch fully erect cock to Emily's torso. It stretched from Emily's pussy, past her belly button and almost touching her tits. Then Emily said exactly what Jess was thinking "I wonder if it will fit". Jess slid in gently, the tip was the hardest bit, but it helped that Emily was literally dripping wet. To start with Jess went as gently as possible, but found with every inch she gave Emily, Emily wanted just a little more until eventually Jess was fucking Emily's brains out. To start with, she wanted to be quiet, but she was losing all sense of control. Now she wanted the whole house to feel her cum. She fucked Emily so hard it made the walls shake. Pictures were falling down and lampshades were swinging. Emily was crying tears of pleasure, every time Emily came Jess felt her whole body cum against her shaft, she stopped counting after 7. Emily soon had no strength left in her, she was willing to just be used by Jess, a flesh light for Jess's pleasure. When Jess was finally done they both lay together for a bit in silence, Emily's hand feeling the deep groves of Jess's 8 pack. When Emily feel asleep Jess got up and went downstairs, she saw Jamie passed out not far from where she'd last seen him. She picked him up and carried him home in her arms. Day 10 Jamie woke up with a splitting headache and patchy memories of the night before. The last thing he remembered was vomitting on the floor in front of everyone trying to impress Emily, then falling asleep on the sofa. He rememberred waking up at one point during what he though... was there an earth quake? The whole house was shaking, a photo had just fallen of the wall and the lamp shade above him was swaying like crazy. Was he just really drunk? What was going on? Was everyone OK? Then her rememberred more, that some of the people were laughing, while some of the guys looked uncomfortable... why did they look worried. Then her remembered what he heard, the loud deep grunts of his sister and the high pitch cries of Emily. Almost the enitre party it seemed had stopped to listen. 30 people sitting in a silent room as the walls swayed. A few of the girls seemed to get off on this and were now making out with the boyfriends, others just looked shocked. Jamie wanted to leave but he was still to drunk and fell back to sleep. But wait, if he didn't leave, how was he in his bed? and even though he was under covers he could tell he was now nude. How was he now naked?! "Morning sleepy head" Jess walked herself in and leant in the doorway. She'd clearly just been for a run as she was glistining in sweat and was wearing her tight yoga pants and white crop top which were way too tight for her. Her cock looked as if it had grown since he'd last seen it and was pressed so tight against the thin fabric that the thick viens were actually visible through the pants. While her tits, which were now bigger than his head were both poking out from under her top. "How... how did I get back here, and how am I naked" he asked rubbing his head. "Well I brought you home, but you got naked yourself" said Jess. "why, why did I do that" asked Jamie. "You wanted to compare cocks" said Jess. "I WHAT!" Jamie said horrified. "I tried to say no but you started pulling it out and I couldn't stop you" said Jess. Jamie's heart was sinking as he remembered the events. Then Jess continued "you pulled out your little 3 inch cock said this is a real cock because you were born a guy, and mine is a fake cock" "oh my god, oh my god, oh my god...." said Jamie out loud now remembering. Then Jess walked up to the end of the bed and continued to talk "then I pulled out this" and to Jamies horror Jess pulled out the thickest 6 inch cock he'd ever seen from her Yoga pants. "Jess what are you doing" cried Jamie, not being about to look at Jess, fixated on the threat in front of him. Jess ignored Jamie "and said Emily didn't seem to care that my fat beast was fake when I fucked her for 4 hours last night." She swayed and it audibly slapped her inner thighs. Jamie was horried, that horse cock had already fucked 3 people - that he knew of - and it was still growing. "Then I said your little 'guy cock' wouldn't be a fair comparrison, so I held it against your bicep" Jess said, using air quotes when saying 'guy cock' for added humiliation. The memory hit him instantly, him tensing his bicep while Jess's held her cock against it, the realisation that his little sisters cock was actually bigger than his arm. Not even a little bit bigger. Jamie would actually wish his biceps were as thick and vieny as her cock. "I said you probably couldn't beat my cock in an arm wrestle haha" she grabbed her cock when she said this and swung it in front of him, the sound of the slap when it her thigh was like a porter house stake smaking a chopping board. "You... you weighed it" Jamie said rememberring. "Oh so you do remember haha" she said - her cock giving a visible twitch. Jamie wondered if it grew as she continued talking "yeah I asked how much do you even lift with those twig arms, you said 5kg, and we put my cock on the kitchen scales and it was 6kg! You basically cant even lift my flaccid cock." "Why are you doing this?" Jamie asked. "You were always been so mean to me. Even when I tried to help you you were mean, you just could handle your little sister helping you. All I wanted was a friend and you were never there for me. Well I'm not your little sister anymore. I can cum more in one go than you could carry with 1 arm. The gym at school had to special order me weights, I can bicep curl 60kg each arm, you know what the means right? If I wanted I could curl your little twig body with 1 arm. I've eaten breakfasts bigger than your now." Jess was clearly enjoying this speach because as she spoke her cock pulsing like crazy and with each pulse was visibly growing in size, getting harder and harder. When she stopped talking it must have been 9 inches, now touching his bed sheets. "Jess what are your doing" said Jamie scared. "So you dont remember everything?" said Jess smiling, "You bet me my cock wasn't bigger than your bicep, and I said if I won, I got to compare my cock to your head, like I did with Emily last night. Dont your remember? Maybe not as you fell asleep." Jess began to pull the covers off Jamie. "No, no I didn't agree to this" Jamie protested "Muuuuuuuum!!". "Mum is out Jamie, and you deffinately did, I remember you being very confident" Jess began to pull the covers off of Jamie, revealing his skinny naked body and erect 4 inch cock, "oh are you enjoying this Jamie, do you like being humiliated by me? Is that as big as it gets" Jamie jumped up and tried to sprint for the door. With no effort Jess grabbed his arm and threw him against the wall. Jamie felt Jess's two large hands on both his shoulders, he tried to pull them off. The hands were still clearly feminine, just huge and covering his whole should blades. Jaime couldn't move, her fully flaccid cock had been 6kg, but now at 10 inches it weighed much much more, holding him tightly in place against the wall. Then Jess said "HOLD IT" so loud and so assertively, it was akin to her using 'the voice' from Dune. Jamie did as she said, if he couldn't avoid this he might as well end it quickly. It took both his hands to hold it to his head, he didnt know what pussy smelt like, but he was sure that's what it reacked of. His skinny arms were bulking at the weight of it he felt it grow what felt like another 2 inches, its erect weight was easily 15kg. He wouldn't be able to do this for long. "haha your fingers can't even wrap around my cock, let alone these" she lifted and flexed her huge biceps. A few seconds in and Jamie was already sweating from holding the cock, he was so focused trying not to show he couldn't handle the wieght of it, that he didn't notice his sister pull out her phone. Jess went "cheeeeese" and just as he looked up he saw the flash. Jamie dropped the cock but it was too late. "Delete it" Jamie shouted. "No way" said Jess, "this was part of the deal. Anyway dont worry, I wont send it to anyone, only Emily wants to see it. She's a freak, she wanted to see if my cock was twice the size of your head. Now I have this photo, we know it is." "No dont show it to Emily! I'll do anything!" said Jamie not thinking. "Anything?" asked Jess, grabbing her cock gently and thinking. Not even Jess's huge hands could make her cock look small as she began to stroke it slowly. "Yes anything, please delete that photo" begged Jamie. "OK, OK, well since my beast is rock hard" she said holding her huge 13 inch cock "and since your little lipstick is hard, I want to see something" Jamie said nothing as Jess walked up to him "I want to see how much more I can cum vs. you." Jamie hated this idea, but he wanted the photo deleted more than anything and agreed. Jess bent down grabbed Jamie's hand and walked him to the bathroom where the two began jacking off while Jess teased Jamie. "What are you thinking about?" she said while performing long strokes her own cock "me fucking the doctor again? You know you told me a bout that last night too, that you think about me fucking when you masturbate. You said it while I carried your home in my big arms. I think you wanted me to know. Are you thinking about fucking Emily with this beast until the room shook." Jamie watched as a large glob of cum dropped from Jess's cock, it was more cum than he had ever seen! But at least she was done before him right? Jamie then came right after Jess, to his humiliation, the taunting from Jess actually made him cum faster. "Holy fuck" Jess continued "are you done already little bro? You know I think you like being humiliated by me and my monster." Jess was still stroking the tip of her cock, although now a little faster. "What do you mean? You came before me? That wasn't even that much cum. I though you could cum pints? Wait why are your still masturbating?" said Jamie confused. "Haha Emily and the Doctor were confused by that" said Jess "that's just my pre-cum". WHAT thought Jamie, Jess's precum was more than he could produce in a week, no a month! "This is me cuming..." Jess said, although it took a few moments for anything to happen. Her thighs began shaking first, then the room shook and then all a sudden he felt Jess's large hand under his arm and without even slowing down, Jess lifted him onto her cock. To Jamies continued shock, he was now sat a foot off the floor lifted only by Jess's burning hot beast. Jamie feeling himself falling forward grabbed onto it with both hands as not to fall forward into the firing line. He began to feel all the muscles surronding him swell and tense. Jamie had thought the cock had been hard when he landed on it, but as climax arroached it was swelling to knew limits before his very eyes. The skin was being streched tight as the cock itself became so hard it felt like steel! Jess clearly hadn't measured herself at climax as the cock under him was deffinately larger than 15 inches and it was now so thick and hard that he barely needed to hold on, it was like sitting on a steel bench. There was a calm before the storm for just a couple of seconds giving Jamie a chance to look down at what he was sat on. There was a vien running down the top centre of his little sisters cock that was as thick as his entire 4 inch erect penis. Both her hands were by her sides, he knew there was nothing but her cock holding him in the air. There was an unblieveable amount of power in his sister now. Then finally, after a couple of seconds which felt like was an eternity - it burst like a fire hose. Hot jet's of cum fired into the toilet. Jess let out a low grunt as it happened, like something a bear would make. This was more than any cum experience he had had, Jess would cum with her whole body. The whole room couldn't help but feel her cum. After there intial burst she would have these surges, Jamie was again needing to cling for dear life as the cock under him bucked and bucked again. He wondered if Jess could even feel him on here. Her muscles had swelled to such intensity that he was like a bug to her. To Jamies horror, the toilet in front of him was actually filling up and he was worried it would over flow, but as it got to rim Jess finally began to slow. The room shook as Jess stepped back, smacked against the back wall. With this Jamie fell to the floor. Jess was breathing deeply her abs were exanding and contracting from her huge deep breaths she was making. Jamie got on his knees and stared at the cum filled toilet in front of him. Jamie now agreed with Jess, even with both arms he could not carry just one of her loads. Something about the overwhelming experience of humiliation had him convinced his sister was now a god. A drip of Jess's cum landed on his shoulder, it was thicker than his arm. He turned around and stood up slowly to see his 7ft 18 year old goddess of a sister breathing deeply above him. He was stood in direct eye line with her belly button. The bush beneath was so thick and large, had they been on him you wouldn't of been able to see his cock. Jess's now softening beast however dropped from the bush proudly, and huge from his chin to his belly button. "If I had that cock" though Jamie "I wouldn't even be able to walk" he looked down at his skinny legs then back to the thick beast. Jamie felt so small in front of it. Jess's cock had more strength, more power than he possed in his whole body. He then picked up his towel and began to clean it, a small part of himself deep inside was screaming, but there was nothing he could do. He felt so small in front of her it felt natural to serve her. Jess looked down confused "fuck Jamie, I actually think I forgot you were there? Did you stay on my cock the hole time? That's impressive haha why are you cleaning my dick?" "Errr, I'm sorry Jess" Jamie said waking up. Why was he doing this?! Why was he saying sorry? "Jesus Jamie, I'm not sure I realised how much bigger I am than you?" Jess then got down on one knee to look at him eye to eye, the way you would a child. She pulled off her shirt, setting free her huge tits and placed the crop top on Jamie where it became more like a dress. Then she picked him up and carried him back to bed. While lying in bed he gradually recovered and rememberred than he would soon be that size too. All he could hope for was that his smoothie would arrive in just a few days. Day 11 Jess was worried, in first period she'd been told that she had to report to the principles office. She was pretty sure it might be because after Gym class yesterday she stayed back and fucked Alice for 3 hours instead of going to classes. But maybe Jamie had complained about the fact that even though she promised to delete the photo of her pathetic brother holding up a meaty cock twice the size of his head, she'd not mentioned anything about not sending it to Emily first... Or maybe they were worried when Emily came in yesterday looking 3 months pregnant with no explanation. Anyway, all her worries were put aside when she saw the principle. Excited she rushed home to tell mum everything, only she had to wait as there mum was already consoling Jamie over something. After waiting a little while Jess walked in and asked "whats going on?" Jamie and their mum were sat at the table "Well, Jamie's is not getting very good grades and errr.. well he is being held back a year" She stood next to jamie so that her right inner thigh was in line with his eye sight, the inner thigh where her 6inch cock was visible, as she saw him glance at it she said "oh, ermmm sorry Jamie" she couldn't beleive this, this was going to be so humilating. "Did you want to tell us something, why did you see the principle after school? are you being held back too" Asked their mum, Jamie looked up at Jess in hope that she was about to deliver some equally bad news. "Err no not exactly, I've actually over performed, and well I didn't tell you this, but I applied to some universities... and well, I've been accepted!" she saw her brother turn white again at the news his little sister will be going to uni and he'd be stuck in school. "Oh Jess thats great news" said their Mum "also the Doctor called, she said she doesn't need any more tests, but she wants to see you again for another sample, said you'd know what that means." Day 12 Jamie didn't know why he was going into school now, he was only going to have to repeat the whole year again. He was sat in first period, when he saw a now-pregnant looking Emily walking in with her two friends, only one of them also looked pregnant now, as well as his Gym teacher. He's was pretty sure he knew why. Just 2 days now until he had his own smoothie and he could become a god too like his little sister, 2 long days. He wasn't sure why his sister was being such a bitch, when she knew he'd soon have a smoothie of his own, maybe she was just enjoying it while it lasts. Emily walked up to him after class, she enjoyed humiliating him too now. "How's it feel jamie know you cant even lift your sisters cock? I can't believe its twice the size of your head, that means your head can probably fit in my pussy haha. It's bigger than your arms too isn't it! I can wrap my fingers round your arm see, I can't even wrap them around Jess's cock when its flaccid. When Jess lifts me its like a weigh nothing, she can almost lift me with just her cock. You're about a foot shorter than me, and skinnier too, I reckon it would lift you easy. Her tits are bigger than your head. Last night she fucked 3 of us for 7 hours. Have you even had sex yet?" This went on and on. When he threatened her with anything she threatened to send the photo around the whole school, that was enough to shut him up. "Also I heard you're getting held back, I am too! So dont worry, I'll be visiting your sister lots at uni and telling you all about it" she said to Jamies further distress. Another year was bad enough, but another year with Emily humiliating him was worse. When Jamie went to gym Jess was in the class too, she'd dont all her exams early and so now mostly worked out. For some reason - and again he knew why - Alice the Gym teacher was looking more pregnant than yesterday and wasn't getting up from her desk, she just told the class to do what they want as she eye'd Jess. Jamie tried to stay away from Jess, especially when he could see the cock swingin freely in the track pants. He could see now that she was lifting 70kg on each arm, she wasn't lieing about being able to lift him then, but she might of undersold how easy this would be for her. Even though her arms were big, he knew this was more than most muscular people could even squat, there was something about the drug that made her unusually strong for her size. Which is probably why her cock weighed so much too. When Jess worked out Jamie noticed she swelled up more than usual too, her muscles would become more defined and the viens thicken. But not only this, she must of found it... pleasurable. Her nipples which were normally huge - even for the size of hetr tits - looked rock hard. She was wearing a loose fitting crop to hoodie, so that when she beant over the underboob was on full display. But Jamie notice notice something new today too, on her right nipple was a large and visible piercing. Jaime getting a little arounds at the sight of his sisters huge tits with a nipple piercing decided to take his energy out on his work out, He decided that because he hadn't worked out in a while, he'd use the bench press machine - and since he was just warming up - he'd start just bench pressing the bar. Only he must have misjudged how long he hadnt worked out, because the bar instantly fell to his chest and he couldnt lift it. He must of been there a full minute before Jess walked over "need some help little brother" she stood over him, ignoring the cock pressed against his head, he looked right up her hoodie at her huge underboob, he didnt know boobs could be so large and so perky. The Nipples were pushing the hoodie out further and he caught a glimpse of the large metal hoop. "erm, yes" he said trying to sound calm. Slowly and intentionally she bent over, giving him an even better view of her tits as she lifted the bar with just one finger. After he got up she handed him some 2kg dumb bells and said "I think you should probably start with these and work up to this brother." What was worse was she wasn't trying to humilate him, she meant it. She hugged him squishing her head against her tits, Emily was wrong, Jess's tits weren't as big as his head, they were definately bigger and heavier too. "I need to finish my work out, I'd ask you to spot me but I think you'd die. Tell mum I wont be home tonight, the principle has invited me over." Day 13 Jess woke up and looked down at Amanda - known to everyone else as Principle - lying on her huge bicep. On the other side, Alice. Though alice looked asleep she was knowingly feeling the contours of Jess's abs. Jess couldn't believe the week she'd had. She could no longer go 12 hours without fucking someone. Not only because she needed the release, but literally women would beg her everywhere she went. It was getting too easy too humilate Jamie now too, in fact, she was actually trying not to but couldn't help herself. The other day she was on the floor looking for her keys and she accidentally lifted the whole sofa with him sat on it. She was pittying him until she rememberred his face in the doctors office when he saw her cock for the first time. How good it felt to be so dominant over someone that had been such an asshole of for so long. Then she rememberred him trying to hold her cock, he was clearly trying to hide how heavy it was, but he was literally shaking and sweating under the weight. It was this thought and the filling of Amandas hand gently feeling towards the base of her penis that caused 'the beast' to wake up. It was at this moment Amanda's husband walked in. "WHAT THE FUCK AMANDA YOU BITCH" he screamed. "You shouldn't have fucked your secratary Phil" Said Amanda not even looking at her husband. In fact only Jess was looking at him, enjoying every second of this. "So because I fucked 1 woman, you'd thought fuck 2 women with that silly strap on?" Phil was pointing to the growing tent under the bedding. Jess knew exactly where this was going. "Not exactly" said Amanda beginning to kiss Jess's neck. "Phil, maybe you should sit down, you might enjoy the show" said Jess calmly. "Why dont you shut up you silly bitch, and while your at it, take that silly toy of yours off!" as he said this he ripped of the sheet revealing Jess's now 13 inch member at full mast. Phil stood back eyes wide holding the sheet like a child with a blanket. "SIT DOWN PHIL" said Amanda. Maybe it was shock of his usually quiet wife telling him what to do, or the sight of the huge woman and her giant cock, but he did as his wife said and sat on the chair at the end of the bed. "Good boy, now get naked", to everyones satisfaction, he obliged. He was a portly man, who had clearly married someone way to hot for him. He sat with his shameful 3 inch flacid cock between his legs as his wife and some other lady he recognised as also working at the school began kissing the giant pole. Jess watched the mans faces as she felt 4 hands and 2 lips gently pleasuring her cock. Jess wanted to tear this mans world apart. Jess lifted Alice onto her face and began licking her out with her huge tunge, Alice was instantly trembling in pleasure. This left only one seat for Phil's wife. To phil's horror Amanda needed no instruction and she began to lower herself on to the giant twitching cock. "wha.. what are you doing to my wife" cried Phil gently. "What you should have done a long time ago" said Jess and with that, she did something she'd wanted to do for a while, rather than ease in gently, she could feel Amanda was wet and due to a couple of kids, slightly loser than others she had fucked, so she slammed it all in one go. "FUUUUUUCK" screamed Amanda as the 200kg goddes started slamming into her pussy. Phil shot up to help his wife, Jess only meant to shove him off but accidentally she kicked him across the room with shocking force. The room was huge and he flew back like a bullet until he smacked against the back wall and was actually knocked fully out. Amanda was going through so much pleasure she could barely notice what was going on. Jess was checking every so often if Phil was alive. After 15-30 minutes she lifted Alice's pussy off her face to looked down to Phil who was now starting to stir "Ahh you're alive! Just in time!" "Phil stay the fuck away I'm fiiiiiiii-uuuuuck! Jess ignore the tiny cock prick and just fuuuuuuucking finish, I cant cum anymore" cried Amanda. Jess had never experienced this before but Amanda had been cumming continuously the entire time Phil was passed out. From the moment her cock entered she had been cumming. But she'd been saving her finale for when Phil woke up. Jess threw Alice to the side and focused on Amanda. Alice fell over like a rag doll, passed out from the pleasure of Jess's tonge inside her. Jess then stood up as if Amanda weighed nothing, Amanda was holding tight to Jess as she stood, however Jess could feel her cock was doing most of supporting. Jess placed both her large hands on Amanda's waist gently before grabbing harder. Jess began to lift Amanda up in the air the full length of her cock before slamming her back down. Then again, and again. Amanda weighed nothing to Jess. "Use me Jess ahhhhh fucking use me, finish inside my, I'm your fucking cock sleeve" cried out Amanda clinging to Jess huge hands. Jess saw Phil begin to stand he looked about 5ft 5' - a bit bigger than Jamie - she must have been almost 8ft now. She was big earlier but now she was cuming she was a bulging raging beast and grunting like an animal, it was hard for her to know for sure, but she was pretty sure her cock swelled even more when she was right about to cum, and Phil was going to get a front row seat. Then it happened. Jess came hard. She made sure she got a few heavy loads into Amanda before pulling out and letting the thick ropes fly 4ft across the room, coating Phil. However she may have misjudged how awake he was. Large amounts of Jess's cum were - unaware to Jess - going into Phil's mouth, he tried to swallow but it was too thick, Phil later swore he could feel the actual sperm moving in his stomach. Jess began to hear Phil choking on her ropes, but didnt care. When Jess finally stopped she realised that Phil nose and mouth were blocked and he couldn't breath. She woke up Amanda who, still waking up from the please, rushed to help her husband. "Come on Phil, cough, cough. good boy little more". Finally with Amandas help he got most of it out and could breath again, when he stood up he was covered in Jess's cum. Jess saw Phil look discustedly at Amandas pregnant cum filled belly. She stood above him "you ever cheat on Amanda again Phil, I'm coming back." Day 14 Jamie woke up exicted, today was the day! He had a plan, he would say he was sick to his mum and stay at home. There was no way he was going to risk missing that parcel this time. He waited by the window for hours looking for the post man. He did not eat or drink or go to the loo, but no one came. Hours passed and eventually he was watching his 8ft sister walk up the drive, either she'd been to the gym or she'd just fucked someone, but she was in her swollen state. She swung through the doorway. "Hey brother, why are you waiting by the door?" she said with a knowing grin. "My smoothie was meant to arrive today, I've been waiting for it for hours" "Oh haha that arrived like two weeks ago" Jess said laughing "I paid for next day delivery". "What? You could do that? Where is it?" Said Jamie in a panic. She sat down wide legged in the chair, revealing no underwear under her short skirt, 7 inch flaccid cock dropping down the cushion, "I was thinking, do I really want my little brat of a brother growing huge muscles and bullying me again" she said with a smirk "so today I took it to school and gave it to Emily"

Jamie wanted nothing more than to be taller and stronger. Jamie was a 5ft skinny guy and was almost always ignored by girls. He was 20 and had not lost his virginity. To top it off he was a bit nerdy looking, but not that smart. At school he would get bullied and while at home he would take his anger out on the only person smaller and weaker than him, his little sister Jess. Jess was 4ft 10, tiny even for her age 18. She was a cute and polite brunette who could always be found reading. She loved reading so much in fact that she was reading text books far beyond her year group that Jamie hadn't even read yet. Jamie and Jess live in Belgium, where you go to Uni at 21. The two were not biological siblings, their mum adopted them both as she'd never married and wanted kids. In fact when Jamie got stuck on his homework, Jess would often try and help him. Jamie had been pulling his hair out over one particularly hard problem for hours. Jess wanting nothing more but to be Jamies friend and to help, came over and looked at it, within a couple minutes she had the answer and had written out all the workings. But Jamie, having a small ego, refused her help, scrunched up the workings and through them away. But that not being enough, in a petty rage he also found her text books she'd saved for and bought herself and destroyed them, in the hope that it would disuade her from helping him again in future. Some time later Jess and Jamie came into some inheritance when a relative they barely knew passed away. Jess saved the money while Jamie spent the full amount on some experimental growth drink he'd heard about. It was on an illegal site and cost his entire inheritance, but he wanted it badly. The advert read as follows: HIGHLY EXPERIMENTAL THIS DRUG WAS DEVELOPED IN NORTH KOREA FOR MILITARY PURPOSES. THE DRUG HAS ONLY BEEN TESTED ON MEN. DO NOT GIVE TO WOMEN. THE DRUG WAS DEEMED TOO EFFECTIVE AND BANNED, AS IT MADE THE USERS TOO POWERFUL AND HARD TO CONTROL. KNOWN SIDE EFFECTS: RAPID MUSCLE GROWTH, HEIGHT GROWTH, STRENGTH AND AGILITY. ADDED SIDE EFFECTS: HUGE COCK GROWTH, BALL GROWTH, SEMEN GROWTH AND PUBE GROWTH. ONLY TAKE ONCE. DRUG TAKES 14 DAYS TO WORK FULLY. Being shy about his purchase, Jamie ticked a box saying 'ship without label' and didn't mention anything to his family about this. Unfortunately for Jamie, the drink arrived a day when he wasn't there. Day 1 Jess was reading her book when she heard the door and signed for the mysterious parcel, "whats Jamie bought now?" Jess thought. The bottle was a stylish metal flask with a label on the side that just read "NOT FOR WOMEN". "Yeah right" she thought maybe he'd just bought a weird smoothie drink a YouTuber promoted. Jamie loved toxic guru videos. However, when she popped the lid it smelt AMAZING. She couldn't get over how good it smelt. She desperately wanted to put the lid back on knowing Jamie would be home soon, but she decided to give a little taste first. She had a sip, then a gulp, then another gulp, "WHAT AM I DOING" she thought, "JAMIE WILL KILL YOU". But she couldn't stop, it tasted too good. Before she knew what she'd done, she'd drunk the whole bottle. "Oh god, oh god, oh god" she thought after she'd finished. Thinking quickly she hid the bottle away at the bottom of the bin, maybe Jamie would just think it got lost in the mail. Almost immediately after she hidden the bottle she felt a burning sensation like she needed to pee, only her whole body was warm. She went to the toilet but nothing happened except she was getting warmer and warmer in her groin. She decided to feel it, her clit was rock hard and crazy sensitive. She began rubbing it gently, it felt insanely intense, she could feel sensation travelling up her spine. After just a minute of doing this, she came harder then she'd ever done in her life and for the first time ever, she squirted. "What on earth" she thought, "the drink couldn't have done that could it??" Calming down she decided to go back to the sofa and read her book, Jamie might be suspicious if he came home and she wasn't where she was always sat. Jamie came home 30minutes later, unlucky for Jess, Jamie asked immediately "Jess was there a parcel for me today?" "No, did you buy something?" Responded Jess casually. "Jess, don't be a brat. I got a notification on my phone saying you signed for my parcel?" "SHIT" Jess thought. Thinking on her feet she responded not looking up "oh err yeah a bottle might have arrived" Jamie getting more annoyed "where is it then shrimp, I paid a lot of money for that drink?" "Erm, well I may uh, I might have drunk it" said Jess meekly looking up. Jamie looked panic struck. "YOU DID WHAT?!" "I'm sorry, I just meant to smell it, but it smelt so good and... I kind of drunk it all" confessed Jess. "You fucking idiot, what have you done! Girls aren't meant to drink that stuff! you're buying me another one!" Said Jamie bright red with rage. "Yes of course! How much was it?" responded Jess. "My whole fucking inheritance!" Said Jamie now shouting. "WHAT?" Jess said thinking he must be exaggerating. "I spent my whole inheritance on that and you are buying me another" shouted Jamie. "Jamie, I'm so so sorry, but there is no way I'm spending that on a smoothie for you, you should have told me about it, what does it do? Cure cancer?" Jess was in shock, why would Jamie spend so much on a smoothie, was he joking? Then a thought hit her, "what do you mean girls aren't meant to drink this?" "It's a growth drug you dumb bitch! But it's only been tested on men, it probably wont even work on you" Jamie started punching a wall with rage. Jess ran up and tried to stop him causing damage, she grabbed his hand and when he turned they both saw something shocking, they were looking eye to eye. Day 2 Jamie woke up enraged. He'd spent the whole evening bullying his sister and forced her to buy another bottle for him. But even knowing another bottle would arrive in 14 days he'd slept awful. How could his sister of be as tall as him already? Will she get taller? Surely it wont be as effective on women. Jamie would soon get some answers. Not being able to sleep he went to get breakfast. Jamie was sat at the breakfast table waiting to be handed his toast when he heard his mum shriek "OH MY GOD JESS". Expecting to see his 5ft sister Jamie was in utter terror. Jess was now stood at a staggering 6ft. It was utterly bizarre to be looking up at tiny little Jess's face. She was the same hight as the door frame, her limbs were stick thin and poking through her pijama's. Jess was in tears and after explaining everything that happened, their mum was immediately taking Jess to the hospital. Jamie was brought with them. He sat next to Jess in the car and felt like a little child sat next to her. Jess had to wear Jamie's clothes, but him being 5ft and her being 6ft, the clothes were much too small for her tall frame. After waiting they were brought into the GP room, they waited for another minute then in walked the most stunning doctor Jamie had ever seen. Long blond hair, a tight skirt and even though they were hidden well, undeniably large breasts concealed under her shirt and lab coat. "The lab results are in" the doctor began to say in a warm friendly voice "and everything is fine. Jess will need to be brought back in for regular tests, but other than your height everything else is normal", then she looked over at Jamie, pushing her glasses up her nose "that was a very stupid thing you did buying that stuff online, you are lucky your sister wasn't harmed." Day 3 Jess woke up to the same sensation as the day before - that she HAD to masturbate - she slid her hands down to feel her clit when the first thing she noticed was that her pubes were getting way thicker. As she felt lower she felt her clit was huge, it felt like it might be an inch long. Rather than rubbing it as normal she pinched and rubbed it up and down, almost as if she was jerking off. The pleasure kept intensifying until again she came. She then got up and admired herself in the mirror, her body was perfection, she was a slim 6ft goodess, but she had noticed a few extra changes today. First she had indeed grown a thick set of pubes. Next her body was more muscular, no longer as twig like as before. She has a tight set of abs appearing and she could see the faint outline of a bicep on each arm, could her muscles be growing too? She could also see that her clit was poking though her bush, she was a little worried about this, she really didn't want that to keep growing. Day 4 Jamie woke up scared, his sister was definitely looking stronger yesterday, what will she look like today? When he came home from school yesterday he was relieved he was still able to wrestle the TV remote off of Jess, but it had be harder than he expected. Jamies jaw dropped when Jess walked into the kitchen, ducking her head under the doorway. She was wearing one of her old tops - not one of the new ones their mum had bought her - which let her abs poke out below. Her six pack was even thicker than yesterday and her biceps slightly larger. But that wasn't why he was shocked, her breasts were noticeably ... well ... large. Two perky water balloons were jiggling as she moved around the kitchen. Her mum walked in, clearly noticing what Jamie had noticed she said "oh honey, we are going to have to buy you a bra" "Oh yeah" Jess said cupping her new toys, they were slightly more than her hands could handle, "but better wait I can feel they are growing still" "fair enough honey" said their mum, "Jamie could you get me the pan off the top shelf". Jamie walked over tried to reach, he was almost there, straining on his tip toes when Jess came from behind saying "dont worry Mum, I've got it" Jamie felt Jess's hand on his shoulder while Jess's breasts rested gently on the back of his head - the closest he'd come to a woman's... well... anything before. Jess effortlessly picked up the pan and placed it on the counter. "I was getting it" Jamie said annoyed. "Your too short Jamie, you needed a stool" said Jess, patting Jamie gently on the head. Jamie thought he could see his sister smirk, she couldn't be enjoying humiliating him could she? Day 5 Today was Jess's first day back at school after everything had changed. She was terrified how everyone would react. Today when she'd woken up, she was slightly taller and slightly stronger, but her focus was on her growing clit. It was now at 3 inches long flaccid. She didn't want to think it, but it kind of looked like a penis. She would care more, but she was having the best orgasms of her life, she decided she'd wait until she saw the doctor again before saying anything. She reached for her tight white top again today, she saw Jamie looking yesterday and knew it drove him crazy. It fit again, only today it was much tighter, her breasts now filling the fabric and a long line of straining cleavage was running down the v-neck. She couldn't believe how perky they were for the size, when she cupped them they were far more than her hands could hold and much heavier than they looked. Despite their weight they sat beautifully on her cheast. She couldn't wait to go for breakfast, Jess knew her tits drove Jamie crazy yesterday, today they were almost twice as large. She loved humiliating Jamie now. As Jess walked in and pretended not to see Jamie staring at her. Despite not really feeling like it, she reached for a cereal box all the way on the highest shelf - just to demonstrate how easy it was for her. She then made a bowl of cereal twice the size of his and sat on the counter top, resting her new larger butt on the surface. Their mum walked in "Oh good Jess you are up, I was thinking today, I know I usually drive you both in, but I was actually thinking you could both walk in today?" "Are you sure Mum? I thought you said the Brockney Street wasn't safe?" Said Jess. Jamie was confused, this is something he'd wanted to do for years, but their mum wouldn't let him. He hated being dropped off by his mum and pleaded he would be sensible and take care of Jess if they walked, but she never let them. What had changed? "Well it isn't safe" said their mum, while she was busy getting her bits ready for work she continued "but I'm less worried now, just take care of your little brother OK?" Jess saw Jamie turn a bright red and shout "what do you mean little brother? I'm 2 years older than her?!" he walking up to their Mum past Jess. Jess noticed as he passed how funny and kind of cute he was when he was angry now. "Oh sorry Jamie" said there mum sweetly "I just meant you're the smaller sibling is all, your sister is so much bigger and stronger now, so she can protect both you if anything goes wrong, but I'm sure everything will be fine". Jess could not believe how amazing this feeling was. Her big bully of a brother, was now her little brother. She decided to rub this in a little more, by lifting up her arm, flexing her bicep and saying "dont worry mum, I'll protect us". Jess surprised herself with this a bit, she'd never flexed her new biceps before. Even with just a small flex the thing was thicker than Jamies leg, though his legs were very skinny. The bicep itself had noticeable vein running down it and was about the size of an apple. Jess saw Jamie clock the growth and leave the room visibly angry and humiliated. Day 6 Jamie had had the worst day ever yesterday. While no one knew Jess was his sister, he had heard everyone in the school talking about her. Everyone wanted to know who the new girl was, probably not realising she'd been there for years. Jess had tried to hold his hand on the way to school, he was certain she was humiliating him now. He hated walking with her. For most of the walk she walked ahead, her new longer legs meant that she walked faster effortlessly. However when it came to Brockney street a homeless man, visibly high, actually stopped Jamie and was getting very pushy. Jamie could see Jess walking on and panicking he cried out "JESS!". Jess turned, walked back, grabbed Jamie's out reached hand and walked them on. When the homeless man tried it on Jess she effortlessly pushed past him. The second Jamie felt safely away from the homeless man he pulled his hand away. Today he knew if he didn't want her help he would need to stay closer to her, where he was safe. He was about to walk in the kitchen when he heard a knock at the door. It was Jess, she was crouching to look through the doorframe, he tits were now so large they were spilling out under her shirt, large puffy nipples pressed so tight against the white fabric you could see the colour and outlying of them easily. "Sorry Jamie, you know your baggy white hoodie? I was hoping I could borrow it, this was my biggest shirt before" Said jess, intentionally choosing that moment to try and pull the shirt over her breasts, only for them to immediately slide back out from under, "only well, it doesnt quite fit me anymore." Jamie knew which on she meant, it was one he'd gotten for Christmas, but everything about it was too big and even the sleeves would dangle over his hands. He was thinking about saying no, but he didn't want to fight. He went to look for it while Jess walked into the room. "Did you hear?" Jess said "They've asked me to join the weightlifting team at school, which means I can use all the weights for free" "What are you weightlifting for?" Jamie said annoyed "you're already a freak of nature!" "I just want to test my new strength" Jess said flexing her biceps in front of him again. They were huge! In just one day it looks like they might have doubled. Yesterday they were big, but they were more skin on muscle, today they were thick protien cannons, with one almost cable sized vein running down each bicep. "I tried bicep curling for the first time. I'd never done it before so I'm not sure whats good. You used to go to the gym right? What did you used to curl?" Jamie knew full well that all he could curl was the 5kg, he'd managed 10kg but only for 1 rep, but he pretended not to remember. "Ahh well I lifted 30kg, which they said was good, but if I'm being honest I wasn't trying that hard" Jess said smiling, knowing full well that no one in the school could possibly come close to her strength, let alone her skinny 'little' brother. 30KG! This was half his weight! His little 18 year sister, who was 4.5ft a week ago could now lift half his weight with one arm! He found the jumper it was actually heavy for him to lift and way oversized for him, but trying to act calm and handed it to her. She pulled it over her head and as she did her breasts looked like they might almost escape from under the top. He watched as she struggled with the jumper, he could see already it wasn't going to fit her already. But he couldn't help take the opportunity to notice her abs had gotten thicker and more meaty too and 2 more had appeared at the bottom, partially obscured by a thick black pubes now poking out above her joggers. "Jesus Jess don't you shave?" said Jamie without thinking. Jess pulled the jumper off, giving up trying to fit into it. "Err well I actually I was going to tell you, I tried to shave last night with your trimmer and it well, the thing is my pubes are quite thick now and I think your little trimmer couldn't quite handle them, but don't worry, I've bought a new stronger one we can both use, should arrive next week." Jamie was desperate for his smoothie to arrive next week and end this humiliation. Day 7 Today Jess put on a new top her mum bought her, she still had her old top, only there was now no way should could wear it without her aolas poking out from under. The new top fit her snuggly and was much more comfortable and best of all it still had lots of cleavage. She was now a staggering 7ft, her legs would dangle off the end of the bed, she was desperate to go back to school, but today was the day she'd go back to see the Doctor for more tests. She was relieved because as she looked in the mirror, her clit was now most definitely a cock. She wasn't sure but she felt like it was a reasonably large one too. That morning their Mum - who had to go to work - agreed with Jess that Jamie should go with her to the doctor, then Jess could walk them both to school. Jamie was left out of all decision making these days. However Jamie's was a little excited because it meant they got to see the insanely hot doctor again. They were both sat in the Doctor's office in chairs side by side, Jess was looking down at her thick thighs next to Jamies twigs. Jess not thinking wrapped her index finger and her thumb around Jamies bicep and said "look Jamie I can wrap my hand around your whole arm." Jamie shook her off "leave me alone". "Oh dont be stroppy" said Jess. "I'm not being stroppy" said Jamie. "You can do mine?" Jess flexed her bicep in front of Jamie while Jamie tried his hardest not to look. "Why would I try that?" Jamie said annoyed. "Because I will hold your hand all the way to school today if you dont" said Jess in a humorless voice. Jamie knew she was serious and obliged. Seemingly knowing 1 hand wouldn't be enough he reached forward with both. Jamie wrapped his hands around her right arm, Jess could feel Jamie gently squeezing it with his fingers. Jess was shocked as she began to realise both Jamies hands wouldn't even have a chance wrapping around her flexed bicep. Curious Jess began to relax her arms to give Jamie a chance. To Jess's delight Jamie clearly could tell what was going on and began to go red when she did this. Even when Jess's bicep was fully relaxed and with both hands, he still could not fully grasp it. Jess was becoming more and more red by the second, except she could tell he wasn't angry anymore, it was to realisation of how much more powerful she was than him. Rubbing it in and taking pleasure in the moment Jess said "come on Jamie I'm not even tensing anymore", sounding almost sounding disappointed in him. Jess could see Jamie using all his force to get his fingers to touch, but there was almost an inch for him to go when the doctor walked in. "Hi Jamie, Hi J..." She paused looking at Jess, who was almost eye level with the 5ft 10" Doctor sat down. "Hey Doc" said Jess in a friendly voice. The Doctor looked shocked as she said "wow Jess, erm wow! You've grown... Would you err, stand up for me please Jess?" Jess obliged and even though he wasn't asked, Jamie did the same. Jess noticed that Jamie being 5ft barely came to the Doctor's chin, while Jess being over 7ft, meant Jamie barely came up to her tits. In fact, without even trying to humiliation Jamie, Jess would walk into him by mistake sometimes when she moved around the house, ocassionally not even noticing she'd knocked him over at all. The Doctor walked up to Jess and began examining Jess's biceps in curiosity. Jess noticed Jamie staring with extreme jealousy as the Doctor admired and stroked the thick cable like vine running down Jess's Bicep with her thumb. "This is all in one week?" she asked breathlessly arching her neck to look up at 7ft Jess. Jess nodded. As Jess felt the doctors hands on her bicep, she began to feel slightly aroused and notice her nipples begin to get hard. Jess knew it would be almost impossible for Jamie and the Doctor not to notice too. While she didn't care about Jamie, she was a little embarrassed when the Doctor saw them. For the first time in a week she blushed and said "err sorry". The doctor chuckled gently "not at all, it's cold in here, can I feel them?" "Errr, sure" said Jess, unsure what the Doctor meant. The Doctor cupped Jess's beasts gently and shook them, almost as if just to test they were really real. Jess was pretty sure this wasn't an official test. "Incredible" she whispered, then coughed almost as if to wake herself up from a dream. She then stepped back so that she could look up at Jess, pushing her glasses up her nose she asked "erm jess, I was doing research on the drug you drank and has there been err... anything else erm, well ... growing?" Jess looked down and saw Jamie looked completely confused by the question, then looked back up at the Doctors bright blue eyes and thought about the question. "oh yeah she said" and perhaps because she was now so big and so strong, but completely without thinking about Jamie being there she pulled her pants down "my clit has well ... gotten bigger". The Doctor and Jamie both went white as they stared at Jess's flaccid 5 inch meaty cock hung in front of them, complete with balls the size of cream eggs. Jess watched as Jamie stepped back, she was sure it was a big one now, but still unsure on how big, she'd never watched porn and was a virgin. Jess was the first to break the silence "I first just thought my clit was growing, but now I'm pretty sure its a penis, because every time I masturbate it cums", Jess said almost as if this were a normal conversation. "Yes Jess, its definitely a penis" responded the Doctor not looking up and almost sounding impressed, "you might want to warn people before pulling that out in future" she said looking at Jamie who was stood mouth wide open and now so white he looked like he might faint. "You said you can cum?" Said the Doctor now curious looking back at Jess. "Yes" said Jess politely. "Would you mind giving me a sample?" Before waiting for a response she turned her head to Jamie and a said "and Jamie, I will need one from you too". "What?" Said Jamie in a horrified voice. The Doctor turned to look at Jamie straight on, "Look in order to check your sister is healthy we need a sample form her, and if there are any issues it would be good to have someone to compare her sample to" she walked over and picked up 2 cups handing one to Jamie and one to Jess. Jess was confused when the cup was given to her "is this for the cum?" Jess asked. "Yes my love" said the Doctor smiling. "Is... there a bigger one" said Jess. The Doctors smile dropped and Jess thought she could see Jamies heart sink even further. She actually felt her cock twitch at the humiliation he must be feeling. She was pretty sure this cup was a lot more than he could fill, but not her. "Will 2 cups do?" asked the doctor, biting her lip a little eyes not looking away from the cock. >> Switching to Jamie's point of view. Jamie had a hard time producing a sample, he couldn't get his sister's flaccid 5 inch monster out of his mind. Despite this he was rock hard from the vision of the Doctor feeling his sisters bicep. He dreamed of that being his bicep. After a little while he'd managed to cum and walked out. Noticing his sister wasn't done he sat down and looked at the small puddle of cum at the bottom of the cup, on the side of the cup it had lines on it going up to half a pint. There's no way his sister could actually fill this he thought. As he thought about this he was in waited a minute, then 5, then 15. Then finally over an hour later, his sister walked out. What was she doing in there? He soon could guess. "No fucking way" he whispered as out walked his sister WITH the Doctor, except the Doctors hair was messed up, no longer in a perfect tight pony tail and her top was wide open so that you could see her bra and her huge cheast which was dripping in sweat. She was pulling her skirt down and looked like she was having trouble walking. How hard could had Jess fucked her? Then a thought occoured. While the doctor towered above him, she was nothing to Jess, Jess could probably lift the doctor with ease with those huge arms. He hadn't noticed before but he could see the bulge now in his sisters pants, stretching down the skin tight jeans. How did that thing belong to his sister? and had she actually just fucked the doctor? Had his 18 year old sister just lost her virginity before him? Suddenly he realised, his little sister, with that cock, if this had of happened already, this was just the beginning. "Oh hi Jamie" the doctor said politely and breathlessly putting her glasses back on "Thanks for waiting, your sister needed some ... errr... assistance". Then he noticed something else, in the Doctor's right hand were 4 filled cups stacked up, some had visibly overflowed with cum dripping down the outside. His little sister had filled 4 whole cups! Then to Jamies continued shock, another nurse walked out of the room pulling up her scrubs! The nurse walked over to the fountain, drank what must of been a liter of water then collapsed in to a chair near Jamie breathing heavily like she'd just run a marathon. It looked like his little sister had not only had sex, but a threesome! This can not be happening he thought. "Oh is that your sample Jamie! Well done" Jamie almost didn't want to hand it over, the cup had probably 10mls of cum in the bottom. He saw Jess strain her eyes to see if there was actually anything in it. The doctor placed it on the top of the pile and looked over at Jess as said heartedly "looks like we wont get these confused". Jamies heart sunk, for the love of GOD, he needed that smoothie. _ On the way to school Jamie had to listen to how incredible sex with the doctor was. "She just kept saying she'd never had a cock so big!" Jess said happily "and then she called in this other nurse to look and she was the same!" Jamie said nothing as Jess continued. "I cant believe I've never had sex before, it's amazing! She said she'd never cum so much before. have you had sex Jamie?" Jamies heart dropped, he was pretty sure she knew the answer. "You've not had sex have you? Does it bother you that I've had sex before you? It's OK if it does." Jamie said nothing as Jess kept talking. "Admit it Jamie, you were scared when you saw my cock". That was it for Jamie as he foolishly retorted "no I wasn't! Anyway how much can that horse cock of yours really grow, bet you can barely get it errect" Jess smiled, she'd clearly wanted Jamie to ask this. Jess clearly took pleasure in the answer "the Doctor wandered that too" Jess said slowly "she said when she measured it, that it was about 11 inches", for the rest of the day Jamie thought about nothing else. Day 8 Jamie was lying in bed, erect, with a measuring tape. He had the tape next to his 4 inch erect cock, and the tape stretched to 5 inches. Jess's flaccid size. He kept thinking about how thick her flaccid cock would look next to his erect one. He looked over at his wrist and thought it was probably thicker than that too. Then he pulled the tape out longer, slowly extending it to the supposedly fully erect 11 inches. His little sister's beast was almost 3 times his and closer to the length of his thigh than his cock. He stared at the tape against his cock, Jess was basically a god next to him. He shamefully came to the thought of his sister fucking the absolute shit out of the Doctor and nurse, then went to the bathroom to clean up. Jess was walking out as he walked up. As always she had the towel tightly wrapped around her tits, but towel which used to drap along the floor now couldn't even fully cover her cock, the tip of which was poking out below. Jess who was un aware - not that she cared - did not see Jamie walking around beneath her and just walked on to her bedroom. When Jamie entered the bathroom the small bin which had been emptied yesterday, was now filled to the top with thick black pubes. Clearly the new trimmer had arrived. Jamie went to pick it up the device - as it had been a while since he'd had a trim - to his shock it was much heaver and bigger than he'd expected. It took 2 hands just to hold it comfortably. Jamie noticed that the thing was so powerful it needed mains power to run. He couldn't help but imagine how easy it must be for his sister to use, this would be nothing for her giant hands and new strength to use. Jamie curious why Jess needed such a device placed it down and picked up a clump of her pubes. The clump was huge and thick, each pube resembled wires more than actually hair. He then tried to pull the clump apart, but couldnt. He pulled harder and harder but it barely budged, even with all his strength it was useless. Then it hit him, he could no longer even win a fight against Jess's pubes. Staring at the huge heavy clump of hair in his hands he was now sure there was not a single part of his sister her was stronger than. He picked up the trimmer again and slowly slid on the power switch and imidiately dropped it in terror, the thing was a practically a hedge trimmer! He was sure that if he was to use that on his cock, it would be more likely to cut his cock off then trim his pubes. He decided to leave it and buy his own smaller trimmer and hide it from his sister. Again he thought about how badly he needed that smoothie. _ Word at school had spread about his sisters 'package' too and that she was his sister. At first he enjoyed the attention until it was pretty clear they just wanted to meet Jess. Despite his sister being 2 years below him girls in his class were begging to be introduced. "Hey Jamie" said the insanely hot Emily from his school house, Emily had never once even looked at him before, "you're the brother of that Jess girl right?" Jamie couldn't believe Emily was even talking to him "err yeah I guess". "Well" Emily started, getting right to the point "would you mind inviting her to my house party tomorrow night, my parents are away, and well, you can come too I guess, but you have to bring Jess". Then after saying just that, she handed him a piece of paper with her address on it and the date and walked off. Day 9 Jess was again standing in front of her bedroom mirror wondering what to wear. Her head was now almost touching the cealing, her cock swinging 6 inches from her thick bush, which despite having been trimmed yesterday, was already starting to grow back thick and fast. Se wondered why Jamie had invited her along to this party tonight even though he seemed to hate her these days. She was thinking it was probably that slut Emily from his class. Only 2 days had passed since Jess's secret got out and Emily had approached her twice. Jess already had her hands on bigger prizes however, the gym teacher Alice had taken a special interest in her. Alice had had suspcions earlier as she'd seen the bulge through Jess's gym gear. Alice was a 30 year old smoking hottie who was always complaining about her shit ass lazy boyfriend. However, until yesterday, Alice hadn't mentioned how bad her boyfriend was in bed, now it's all she could talk about. "I just dont feel satisfied by him tbh", "he cant even get me pregnant" and "tbh - and I cant believe I'm saying this to a pupil, but I really just want to be fucked hard". Tomorrow she was going to give Alice what she wanted. She slid on the only jeans that fit, and with effort slid a white v-neck top over her huge tits and left to walk Jamie to the party. While on their way out their Mum stopped them "wait! Have a great time at the party and Jess look out for your li-big brother. Dont let anyone hurt him OK". "What are you saying Mum? I'm should be looking out for Jess?" Said Jamie, but even he knew that in reality, Jess really was watching over him. Jess just ignored Jamie "dont worry Mum I will keep him safe". On the way to the party they went to get booze. Jamie went first, but got rejected buying 20 light beers because they assumed his actualy valid 20 year old ID was fake. So Jess then went in and got served instantly, she came out carrying two 20 bottle beer crates of extra strong ales under each arm. "What are you doing?" protested Jamie "I can't drink all that?" "Relax" responded Jess, "I bought them and I hate that light shit. Anyway most of these are for me, you'll only need a couple". "Just because your big doesnt mean you can out drink me, I'm still a guy" said jamie clearly annoyed. Jess was ready for this though when she responded "I'm over 7ft Jamie and your 5ft. I barely see you when I'm walking round the house and I am willing to bet my cock is thicker than your arms now. I doubt you could even drink half as much as me". Jamie said nothing. When they arrived, Jess made sure everyone knew that she got served while little Jamie didn't. Jess watched as Jamie went to get a drink when Emily came over. Emily was looking better than Jess expected, she was wearing a bra-like top and jean shorts she hadn't notice before how great her tits looked, which were usually hidden under a school shirt. Things were a bit of a blur, but soon Jess and Emily were sat on a sofa making out and chatting amoungst a busy room full of people. Jess caught Jamie walking by and catching a glimpses of Emily - the hottest girl in his class - gently and knowingly resting her hand on Jess's cock bulge. Emily was getting Jess drink after drink, but Jess was barely feeling drunk. "You got anything stronger?" whispered Jess in Emily's ear. "Stronger? You've had 30 beers, you should be dead!" responded Emily getting up. She returned with a big bottle of whiskey just as Jamie walked over. Jamie had been quitely watching as her sister drank 30 of their 40 beers, Jamie had had 4 and was already wasted. "Give me some Emily" said Jamie drunkenly. "No way you are wasted" said Emily, but just as she said that he grabbed the bottle. Just before he chugged it, he wisely chose to pour out a small shot into a glass before downing it. This didn't help though, as he immediately threw up on Emily's carpet in front of everyone. "What the fuck Jamie!" cried Emily. "Aww dont get angry at him Emily, he's only small, this like a pint glass to him" she said picking up the small shot glass, looking straight at Emily and not even acknowledging him. Jamie clearly drunk and angry wanted to prove himself, "Shut up! I'm not a kid. I can drink it. I was just surprised by the taste. Give it to me again!" He went to grab the bottle, but Jess got to it first, she barely noticed him clinging to it as she pulled the bottle towards her with Jamie attached. Jamie let got before she could lift him up with it. 'Smart move Jamie' she thought as she sniffed the bottle, then to Jamie's and the room's surprise, she began to drink 70% whiskey straight from the bottle. Jess expected this to go badly, but she couldn't actually sit and watch Jamie drink and embarrass himself anymore. To her shock however, she really enjoyed the first gulp. Then the second. Then the third. Before she knew it, she was drinking the whole bottle to a cheering room. Everyone but Jamie was chanting "We like to drink with Jess, because Jess is our mate, and when we drink with Jess, she downs it all in 8! 8! 7! 6!" But before they could get to 5, the bottle was finished, she placed the bottle on the table as the room cheered in admiration. "Holy shit Jess! are you ok?!" shouted Emily. "Fuck yeah that was amazing!" said Jess enthusiatically and leant in to kiss her, Jess could feel her huge tongue filling Emily's mouth. Jess then felt Emily's hand slide up her top, Emily's small hands could barely grab Jess's huge aola's. Jess leant back and said with a small feminine burp "I'm deffinately feeling a little drunk now". Emily leant in and whispered in Jess's ear "how about we go up stairs and lie down". Jess was pretty happy with this idea and left Jamie sat on the sofa looking annoyed but also about to pass out. As they walked up Jess caught the envious eyes of all the men watching her. Which to her surprise, made her cock begin to twitch like crazy. She wondered if there was a signle man here that was bigger than her beast? Almost before the door was shut, Emily was already undressing, pulling off her shorts, revealing no underwear. Jess pulled off her top setting her tits free, she began to pull her jeans down when Emily stopped her to ask if she could do it. Jess nodded. Emily pulled off the top button, then the second, then the third. Emily could now see the base of the cock and whispered "holy shit", Jess closed her eyes as she felt Emilys tiny hands wrap around the base and with all her strength Emily began to pull the cock free from Jess's skin tight jeans. Jess felt her cock break free from its tight prison and instantly begin to swell. "I cant wrap my hand around it" said Emily almost in fear, Jess looked down at her still mostly flaccid cock to see that while Emily had mostly gotten her hands around it, should could indeed not fully grasp it. "Is that bad" she asked geniunely. "Its amazing" said Emily not looking up and leaning in to kiss it gently. Jess felt it fill with blood. Emily took turns stroking Jess's cock with both hands, cupping her balls and rubbing her own clit. Emily couldn't stop talking, "fuck its gets bigger?", "Its still fucking growing!" and "Jesus christ, it bigger than my head". Emily held her face against the now rock hard cock, it wasnt just bigger is was a safe few inches bigger. Jess pulled a condom out her pocket "I err stole this from Jamie, I doubt he will be needing it any time soon". Emily let out a loud "HA" then continued "you think that will fit this?" she said shaking Jess cock and smaking it against her head. "It wont? Can't they like - stretch a lot?" Jess asked. "Everything has limits Jess, but sure we can try" said Emily, pulling out the condom and attempting the place it on Jess's cock. Jess could see what Emily meant. It wasnt so much just the length, more the thickness. Emily as gently as posible managed to start getting the condom over the tip of Jess cock, but again Emily's tiny hands on her beast made her twitch. A small glob of precum slipped out, filling the condom instantly. "Did you cum?" asked Emily confused. "No that err just happens in the build up" said Jess slightly embarrsed, blushing again. "You mean to say that this is pre-cum" holding the small water ballon next to her head. Jess again nodded. Emily excited laid on the bed, Jess pulled off her jeans and walked over. She rested her cock on Emilys chest as Emily wrapped her legs around Jess's waist. Jess watched as Emily's two hands played curiously with her cock. Jess was comparing her 11 inch fully erect cock to Emily's torso. It stretched from Emily's pussy, past her belly button and almost touching her tits. Then Emily said exactly what Jess was thinking "I wonder if it will fit". Jess slid in gently, the tip was the hardest bit, but it helped that Emily was literally dripping wet. To start with Jess went as gently as possible, but found with every inch she gave Emily, Emily wanted just a little more until eventually Jess was fucking Emily's brains out. To start with, she wanted to be quiet, but she was losing all sense of control. Now she wanted the whole house to feel her cum. She fucked Emily so hard it made the walls shake. Pictures were falling down and lampshades were swinging. Emily was crying tears of pleasure, every time Emily came Jess felt her whole body cum against her shaft, she stopped counting after 7. Emily soon had no strength left in her, she was willing to just be used by Jess, a flesh light for Jess's pleasure. When Jess was finally done they both lay together for a bit in silence, Emily's hand feeling the deep groves of Jess's 8 pack. When Emily feel asleep Jess got up and went downstairs, she saw Jamie passed out not far from where she'd last seen him. She picked him up and carried him home in her arms. Day 10 Jamie woke up with a splitting headache and patchy memories of the night before. The last thing he remembered was vomitting on the floor in front of everyone trying to impress Emily, then falling asleep on the sofa. He rememberred waking up at one point during what he though... was there an earth quake? The whole house was shaking, a photo had just fallen of the wall and the lamp shade above him was swaying like crazy. Was he just really drunk? What was going on? Was everyone OK? Then her rememberred more, that some of the people were laughing, while some of the guys looked uncomfortable... why did they look worried. Then her remembered what he heard, the loud deep grunts of his sister and the high pitch cries of Emily. Almost the enitre party it seemed had stopped to listen. 30 people sitting in a silent room as the walls swayed. A few of the girls seemed to get off on this and were now making out with the boyfriends, others just looked shocked. Jamie wanted to leave but he was still to drunk and fell back to sleep. But wait, if he didn't leave, how was he in his bed? and even though he was under covers he could tell he was now nude. How was he now naked?! "Morning sleepy head" Jess walked herself in and leant in the doorway. She'd clearly just been for a run as she was glistining in sweat and was wearing her tight yoga pants and white crop top which were way too tight for her. Her cock looked as if it had grown since he'd last seen it and was pressed so tight against the thin fabric that the thick viens were actually visible through the pants. While her tits, which were now bigger than his head were both poking out from under her top. "How... how did I get back here, and how am I naked" he asked rubbing his head. "Well I brought you home, but you got naked yourself" said Jess. "why, why did I do that" asked Jamie. "You wanted to compare cocks" said Jess. "I WHAT!" Jamie said horrified. "I tried to say no but you started pulling it out and I couldn't stop you" said Jess. Jamie's heart was sinking as he remembered the events. Then Jess continued "you pulled out your little 3 inch cock said this is a real cock because you were born a guy, and mine is a fake cock" "oh my god, oh my god, oh my god...." said Jamie out loud now remembering. Then Jess walked up to the end of the bed and continued to talk "then I pulled out this" and to Jamies horror Jess pulled out the thickest 6 inch cock he'd ever seen from her Yoga pants. "Jess what are you doing" cried Jamie, not being about to look at Jess, fixated on the threat in front of him. Jess ignored Jamie "and said Emily didn't seem to care that my fat beast was fake when I fucked her for 4 hours last night." She swayed and it audibly slapped her inner thighs. Jamie was horried, that horse cock had already fucked 3 people - that he knew of - and it was still growing. "Then I said your little 'guy cock' wouldn't be a fair comparrison, so I held it against your bicep" Jess said, using air quotes when saying 'guy cock' for added humiliation. The memory hit him instantly, him tensing his bicep while Jess's held her cock against it, the realisation that his little sisters cock was actually bigger than his arm. Not even a little bit bigger. Jamie would actually wish his biceps were as thick and vieny as her cock. "I said you probably couldn't beat my cock in an arm wrestle haha" she grabbed her cock when she said this and swung it in front of him, the sound of the slap when it her thigh was like a porter house stake smaking a chopping board. "You... you weighed it" Jamie said rememberring. "Oh so you do remember haha" she said - her cock giving a visible twitch. Jamie wondered if it grew as she continued talking "yeah I asked how much do you even lift with those twig arms, you said 5kg, and we put my cock on the kitchen scales and it was 6kg! You basically cant even lift my flaccid cock." "Why are you doing this?" Jamie asked. "You were always been so mean to me. Even when I tried to help you you were mean, you just could handle your little sister helping you. All I wanted was a friend and you were never there for me. Well I'm not your little sister anymore. I can cum more in one go than you could carry with 1 arm. The gym at school had to special order me weights, I can bicep curl 60kg each arm, you know what the means right? If I wanted I could curl your little twig body with 1 arm. I've eaten breakfasts bigger than your now." Jess was clearly enjoying this speach because as she spoke her cock pulsing like crazy and with each pulse was visibly growing in size, getting harder and harder. When she stopped talking it must have been 9 inches, now touching his bed sheets. "Jess what are your doing" said Jamie scared. "So you dont remember everything?" said Jess smiling, "You bet me my cock wasn't bigger than your bicep, and I said if I won, I got to compare my cock to your head, like I did with Emily last night. Dont your remember? Maybe not as you fell asleep." Jess began to pull the covers off Jamie. "No, no I didn't agree to this" Jamie protested "Muuuuuuuum!!". "Mum is out Jamie, and you deffinately did, I remember you being very confident" Jess began to pull the covers off of Jamie, revealing his skinny naked body and erect 4 inch cock, "oh are you enjoying this Jamie, do you like being humiliated by me? Is that as big as it gets" Jamie jumped up and tried to sprint for the door. With no effort Jess grabbed his arm and threw him against the wall. Jamie felt Jess's two large hands on both his shoulders, he tried to pull them off. The hands were still clearly feminine, just huge and covering his whole should blades. Jaime couldn't move, her fully flaccid cock had been 6kg, but now at 10 inches it weighed much much more, holding him tightly in place against the wall. Then Jess said "HOLD IT" so loud and so assertively, it was akin to her using 'the voice' from Dune. Jamie did as she said, if he couldn't avoid this he might as well end it quickly. It took both his hands to hold it to his head, he didnt know what pussy smelt like, but he was sure that's what it reacked of. His skinny arms were bulking at the weight of it he felt it grow what felt like another 2 inches, its erect weight was easily 15kg. He wouldn't be able to do this for long. "haha your fingers can't even wrap around my cock, let alone these" she lifted and flexed her huge biceps. A few seconds in and Jamie was already sweating from holding the cock, he was so focused trying not to show he couldn't handle the wieght of it, that he didn't notice his sister pull out her phone. Jess went "cheeeeese" and just as he looked up he saw the flash. Jamie dropped the cock but it was too late. "Delete it" Jamie shouted. "No way" said Jess, "this was part of the deal. Anyway dont worry, I wont send it to anyone, only Emily wants to see it. She's a freak, she wanted to see if my cock was twice the size of your head. Now I have this photo, we know it is." "No dont show it to Emily! I'll do anything!" said Jamie not thinking. "Anything?" asked Jess, grabbing her cock gently and thinking. Not even Jess's huge hands could make her cock look small as she began to stroke it slowly. "Yes anything, please delete that photo" begged Jamie. "OK, OK, well since my beast is rock hard" she said holding her huge 13 inch cock "and since your little lipstick is hard, I want to see something" Jamie said nothing as Jess walked up to him "I want to see how much more I can cum vs. you." Jamie hated this idea, but he wanted the photo deleted more than anything and agreed. Jess bent down grabbed Jamie's hand and walked him to the bathroom where the two began jacking off while Jess teased Jamie. "What are you thinking about?" she said while performing long strokes her own cock "me fucking the doctor again? You know you told me a bout that last night too, that you think about me fucking when you masturbate. You said it while I carried your home in my big arms. I think you wanted me to know. Are you thinking about fucking Emily with this beast until the room shook." Jamie watched as a large glob of cum dropped from Jess's cock, it was more cum than he had ever seen! But at least she was done before him right? Jamie then came right after Jess, to his humiliation, the taunting from Jess actually made him cum faster. "Holy fuck" Jess continued "are you done already little bro? You know I think you like being humiliated by me and my monster." Jess was still stroking the tip of her cock, although now a little faster. "What do you mean? You came before me? That wasn't even that much cum. I though you could cum pints? Wait why are your still masturbating?" said Jamie confused. "Haha Emily and the Doctor were confused by that" said Jess "that's just my pre-cum". WHAT thought Jamie, Jess's precum was more than he could produce in a week, no a month! "This is me cuming..." Jess said, although it took a few moments for anything to happen. Her thighs began shaking first, then the room shook and then all a sudden he felt Jess's large hand under his arm and without even slowing down, Jess lifted him onto her cock. To Jamies continued shock, he was now sat a foot off the floor lifted only by Jess's burning hot beast. Jamie feeling himself falling forward grabbed onto it with both hands as not to fall forward into the firing line. He began to feel all the muscles surronding him swell and tense. Jamie had thought the cock had been hard when he landed on it, but as climax arroached it was swelling to knew limits before his very eyes. The skin was being streched tight as the cock itself became so hard it felt like steel! Jess clearly hadn't measured herself at climax as the cock under him was deffinately larger than 15 inches and it was now so thick and hard that he barely needed to hold on, it was like sitting on a steel bench. There was a calm before the storm for just a couple of seconds giving Jamie a chance to look down at what he was sat on. There was a vien running down the top centre of his little sisters cock that was as thick as his entire 4 inch erect penis. Both her hands were by her sides, he knew there was nothing but her cock holding him in the air. There was an unblieveable amount of power in his sister now. Then finally, after a couple of seconds which felt like was an eternity - it burst like a fire hose. Hot jet's of cum fired into the toilet. Jess let out a low grunt as it happened, like something a bear would make. This was more than any cum experience he had had, Jess would cum with her whole body. The whole room couldn't help but feel her cum. After there intial burst she would have these surges, Jamie was again needing to cling for dear life as the cock under him bucked and bucked again. He wondered if Jess could even feel him on here. Her muscles had swelled to such intensity that he was like a bug to her. To Jamies horror, the toilet in front of him was actually filling up and he was worried it would over flow, but as it got to rim Jess finally began to slow. The room shook as Jess stepped back, smacked against the back wall. With this Jamie fell to the floor. Jess was breathing deeply her abs were exanding and contracting from her huge deep breaths she was making. Jamie got on his knees and stared at the cum filled toilet in front of him. Jamie now agreed with Jess, even with both arms he could not carry just one of her loads. Something about the overwhelming experience of humiliation had him convinced his sister was now a god. A drip of Jess's cum landed on his shoulder, it was thicker than his arm. He turned around and stood up slowly to see his 7ft 18 year old goddess of a sister breathing deeply above him. He was stood in direct eye line with her belly button. The bush beneath was so thick and large, had they been on him you wouldn't of been able to see his cock. Jess's now softening beast however dropped from the bush proudly, and huge from his chin to his belly button. "If I had that cock" though Jamie "I wouldn't even be able to walk" he looked down at his skinny legs then back to the thick beast. Jamie felt so small in front of it. Jess's cock had more strength, more power than he possed in his whole body. He then picked up his towel and began to clean it, a small part of himself deep inside was screaming, but there was nothing he could do. He felt so small in front of her it felt natural to serve her. Jess looked down confused "fuck Jamie, I actually think I forgot you were there? Did you stay on my cock the hole time? That's impressive haha why are you cleaning my dick?" "Errr, I'm sorry Jess" Jamie said waking up. Why was he doing this?! Why was he saying sorry? "Jesus Jamie, I'm not sure I realised how much bigger I am than you?" Jess then got down on one knee to look at him eye to eye, the way you would a child. She pulled off her shirt, setting free her huge tits and placed the crop top on Jamie where it became more like a dress. Then she picked him up and carried him back to bed. While lying in bed he gradually recovered and rememberred than he would soon be that size too. All he could hope for was that his smoothie would arrive in just a few days. Day 11 Jess was worried, in first period she'd been told that she had to report to the principles office. She was pretty sure it might be because after Gym class yesterday she stayed back and fucked Alice for 3 hours instead of going to classes. But maybe Jamie had complained about the fact that even though she promised to delete the photo of her pathetic brother holding up a meaty cock twice the size of his head, she'd not mentioned anything about not sending it to Emily first... Or maybe they were worried when Emily came in yesterday looking 3 months pregnant with no explanation. Anyway, all her worries were put aside when she saw the principle. Excited she rushed home to tell mum everything, only she had to wait as there mum was already consoling Jamie over something. After waiting a little while Jess walked in and asked "whats going on?" Jamie and their mum were sat at the table "Well, Jamie's is not getting very good grades and errr.. well he is being held back a year" She stood next to jamie so that her right inner thigh was in line with his eye sight, the inner thigh where her 6inch cock was visible, as she saw him glance at it she said "oh, ermmm sorry Jamie" she couldn't beleive this, this was going to be so humilating. "Did you want to tell us something, why did you see the principle after school? are you being held back too" Asked their mum, Jamie looked up at Jess in hope that she was about to deliver some equally bad news. "Err no not exactly, I've actually over performed, and well I didn't tell you this, but I applied to some universities... and well, I've been accepted!" she saw her brother turn white again at the news his little sister will be going to uni and he'd be stuck in school. "Oh Jess thats great news" said their Mum "also the Doctor called, she said she doesn't need any more tests, but she wants to see you again for another sample, said you'd know what that means." Day 12 Jamie didn't know why he was going into school now, he was only going to have to repeat the whole year again. He was sat in first period, when he saw a now-pregnant looking Emily walking in with her two friends, only one of them also looked pregnant now, as well as his Gym teacher. He's was pretty sure he knew why. Just 2 days now until he had his own smoothie and he could become a god too like his little sister, 2 long days. He wasn't sure why his sister was being such a bitch, when she knew he'd soon have a smoothie of his own, maybe she was just enjoying it while it lasts. Emily walked up to him after class, she enjoyed humiliating him too now. "How's it feel jamie know you cant even lift your sisters cock? I can't believe its twice the size of your head, that means your head can probably fit in my pussy haha. It's bigger than your arms too isn't it! I can wrap my fingers round your arm see, I can't even wrap them around Jess's cock when its flaccid. When Jess lifts me its like a weigh nothing, she can almost lift me with just her cock. You're about a foot shorter than me, and skinnier too, I reckon it would lift you easy. Her tits are bigger than your head. Last night she fucked 3 of us for 7 hours. Have you even had sex yet?" This went on and on. When he threatened her with anything she threatened to send the photo around the whole school, that was enough to shut him up. "Also I heard you're getting held back, I am too! So dont worry, I'll be visiting your sister lots at uni and telling you all about it" she said to Jamies further distress. Another year was bad enough, but another year with Emily humiliating him was worse. When Jamie went to gym Jess was in the class too, she'd dont all her exams early and so now mostly worked out. For some reason - and again he knew why - Alice the Gym teacher was looking more pregnant than yesterday and wasn't getting up from her desk, she just told the class to do what they want as she eye'd Jess. Jamie tried to stay away from Jess, especially when he could see the cock swingin freely in the track pants. He could see now that she was lifting 70kg on each arm, she wasn't lieing about being able to lift him then, but she might of undersold how easy this would be for her. Even though her arms were big, he knew this was more than most muscular people could even squat, there was something about the drug that made her unusually strong for her size. Which is probably why her cock weighed so much too. When Jess worked out Jamie noticed she swelled up more than usual too, her muscles would become more defined and the viens thicken. But not only this, she must of found it... pleasurable. Her nipples which were normally huge - even for the size of hetr tits - looked rock hard. She was wearing a loose fitting crop to hoodie, so that when she beant over the underboob was on full display. But Jamie notice notice something new today too, on her right nipple was a large and visible piercing. Jaime getting a little arounds at the sight of his sisters huge tits with a nipple piercing decided to take his energy out on his work out, He decided that because he hadn't worked out in a while, he'd use the bench press machine - and since he was just warming up - he'd start just bench pressing the bar. Only he must have misjudged how long he hadnt worked out, because the bar instantly fell to his chest and he couldnt lift it. He must of been there a full minute before Jess walked over "need some help little brother" she stood over him, ignoring the cock pressed against his head, he looked right up her hoodie at her huge underboob, he didnt know boobs could be so large and so perky. The Nipples were pushing the hoodie out further and he caught a glimpse of the large metal hoop. "erm, yes" he said trying to sound calm. Slowly and intentionally she bent over, giving him an even better view of her tits as she lifted the bar with just one finger. After he got up she handed him some 2kg dumb bells and said "I think you should probably start with these and work up to this brother." What was worse was she wasn't trying to humilate him, she meant it. She hugged him squishing her head against her tits, Emily was wrong, Jess's tits weren't as big as his head, they were definately bigger and heavier too. "I need to finish my work out, I'd ask you to spot me but I think you'd die. Tell mum I wont be home tonight, the principle has invited me over." Day 13 Jess woke up and looked down at Amanda - known to everyone else as Principle - lying on her huge bicep. On the other side, Alice. Though alice looked asleep she was knowingly feeling the contours of Jess's abs. Jess couldn't believe the week she'd had. She could no longer go 12 hours without fucking someone. Not only because she needed the release, but literally women would beg her everywhere she went. It was getting too easy too humilate Jamie now too, in fact, she was actually trying not to but couldn't help herself. The other day she was on the floor looking for her keys and she accidentally lifted the whole sofa with him sat on it. She was pittying him until she rememberred his face in the doctors office when he saw her cock for the first time. How good it felt to be so dominant over someone that had been such an asshole of for so long. Then she rememberred him trying to hold her cock, he was clearly trying to hide how heavy it was, but he was literally shaking and sweating under the weight. It was this thought and the filling of Amandas hand gently feeling towards the base of her penis that caused 'the beast' to wake up. It was at this moment Amanda's husband walked in. "WHAT THE FUCK AMANDA YOU BITCH" he screamed. "You shouldn't have fucked your secratary Phil" Said Amanda not even looking at her husband. In fact only Jess was looking at him, enjoying every second of this. "So because I fucked 1 woman, you'd thought fuck 2 women with that silly strap on?" Phil was pointing to the growing tent under the bedding. Jess knew exactly where this was going. "Not exactly" said Amanda beginning to kiss Jess's neck. "Phil, maybe you should sit down, you might enjoy the show" said Jess calmly. "Why dont you shut up you silly bitch, and while your at it, take that silly toy of yours off!" as he said this he ripped of the sheet revealing Jess's now 13 inch member at full mast. Phil stood back eyes wide holding the sheet like a child with a blanket. "SIT DOWN PHIL" said Amanda. Maybe it was shock of his usually quiet wife telling him what to do, or the sight of the huge woman and her giant cock, but he did as his wife said and sat on the chair at the end of the bed. "Good boy, now get naked", to everyones satisfaction, he obliged. He was a portly man, who had clearly married someone way to hot for him. He sat with his shameful 3 inch flacid cock between his legs as his wife and some other lady he recognised as also working at the school began kissing the giant pole. Jess watched the mans faces as she felt 4 hands and 2 lips gently pleasuring her cock. Jess wanted to tear this mans world apart. Jess lifted Alice onto her face and began licking her out with her huge tunge, Alice was instantly trembling in pleasure. This left only one seat for Phil's wife. To phil's horror Amanda needed no instruction and she began to lower herself on to the giant twitching cock. "wha.. what are you doing to my wife" cried Phil gently. "What you should have done a long time ago" said Jess and with that, she did something she'd wanted to do for a while, rather than ease in gently, she could feel Amanda was wet and due to a couple of kids, slightly loser than others she had fucked, so she slammed it all in one go. "FUUUUUUCK" screamed Amanda as the 200kg goddes started slamming into her pussy. Phil shot up to help his wife, Jess only meant to shove him off but accidentally she kicked him across the room with shocking force. The room was huge and he flew back like a bullet until he smacked against the back wall and was actually knocked fully out. Amanda was going through so much pleasure she could barely notice what was going on. Jess was checking every so often if Phil was alive. After 15-30 minutes she lifted Alice's pussy off her face to looked down to Phil who was now starting to stir "Ahh you're alive! Just in time!" "Phil stay the fuck away I'm fiiiiiiii-uuuuuck! Jess ignore the tiny cock prick and just fuuuuuuucking finish, I cant cum anymore" cried Amanda. Jess had never experienced this before but Amanda had been cumming continuously the entire time Phil was passed out. From the moment her cock entered she had been cumming. But she'd been saving her finale for when Phil woke up. Jess threw Alice to the side and focused on Amanda. Alice fell over like a rag doll, passed out from the pleasure of Jess's tonge inside her. Jess then stood up as if Amanda weighed nothing, Amanda was holding tight to Jess as she stood, however Jess could feel her cock was doing most of supporting. Jess placed both her large hands on Amanda's waist gently before grabbing harder. Jess began to lift Amanda up in the air the full length of her cock before slamming her back down. Then again, and again. Amanda weighed nothing to Jess. "Use me Jess ahhhhh fucking use me, finish inside my, I'm your fucking cock sleeve" cried out Amanda clinging to Jess huge hands. Jess saw Phil begin to stand he looked about 5ft 5' - a bit bigger than Jamie - she must have been almost 8ft now. She was big earlier but now she was cuming she was a bulging raging beast and grunting like an animal, it was hard for her to know for sure, but she was pretty sure her cock swelled even more when she was right about to cum, and Phil was going to get a front row seat. Then it happened. Jess came hard. She made sure she got a few heavy loads into Amanda before pulling out and letting the thick ropes fly 4ft across the room, coating Phil. However she may have misjudged how awake he was. Large amounts of Jess's cum were - unaware to Jess - going into Phil's mouth, he tried to swallow but it was too thick, Phil later swore he could feel the actual sperm moving in his stomach. Jess began to hear Phil choking on her ropes, but didnt care. When Jess finally stopped she realised that Phil nose and mouth were blocked and he couldn't breath. She woke up Amanda who, still waking up from the please, rushed to help her husband. "Come on Phil, cough, cough. good boy little more". Finally with Amandas help he got most of it out and could breath again, when he stood up he was covered in Jess's cum. Jess saw Phil look discustedly at Amandas pregnant cum filled belly. She stood above him "you ever cheat on Amanda again Phil, I'm coming back." Day 14 Jamie woke up exicted, today was the day! He had a plan, he would say he was sick to his mum and stay at home. There was no way he was going to risk missing that parcel this time. He waited by the window for hours looking for the post man. He did not eat or drink or go to the loo, but no one came. Hours passed and eventually he was watching his 8ft sister walk up the drive, either she'd been to the gym or she'd just fucked someone, but she was in her swollen state. She swung through the doorway. "Hey brother, why are you waiting by the door?" she said with a knowing grin. "My smoothie was meant to arrive today, I've been waiting for it for hours" "Oh haha that arrived like two weeks ago" Jess said laughing "I paid for next day delivery". "What? You could do that? Where is it?" Said Jamie in a panic. She sat down wide legged in the chair, revealing no underwear under her short skirt, 7 inch flaccid cock dropping down the cushion, "I was thinking, do I really want my little brat of a brother growing huge muscles and bullying me again" she said with a smirk "so today I took it to school and gave it to Emily"

Jamie wanted nothing more than to be taller and stronger. Jamie was a 5ft skinny guy and was almost always ignored by girls. He was 20 and had not lost his virginity. To top it off he was a bit nerdy looking, but not that smart. At school he would get bullied and while at home he would take his anger out on the only person smaller and weaker than him, his little sister Jess. Jess was 4ft 10, tiny even for her age 18. She was a cute and polite brunette who could always be found reading. She loved reading so much in fact that she was reading text books far beyond her year group that Jamie hadn't even read yet. Jamie and Jess live in Belgium, where you go to Uni at 21. The two were not biological siblings, their mum adopted them both as she'd never married and wanted kids. In fact when Jamie got stuck on his homework, Jess would often try and help him. Jamie had been pulling his hair out over one particularly hard problem for hours. Jess wanting nothing more but to be Jamies friend and to help, came over and looked at it, within a couple minutes she had the answer and had written out all the workings. But Jamie, having a small ego, refused her help, scrunched up the workings and through them away. But that not being enough, in a petty rage he also found her text books she'd saved for and bought herself and destroyed them, in the hope that it would disuade her from helping him again in future. Some time later Jess and Jamie came into some inheritance when a relative they barely knew passed away. Jess saved the money while Jamie spent the full amount on some experimental growth drink he'd heard about. It was on an illegal site and cost his entire inheritance, but he wanted it badly. The advert read as follows: HIGHLY EXPERIMENTAL THIS DRUG WAS DEVELOPED IN NORTH KOREA FOR MILITARY PURPOSES. THE DRUG HAS ONLY BEEN TESTED ON MEN. DO NOT GIVE TO WOMEN. THE DRUG WAS DEEMED TOO EFFECTIVE AND BANNED, AS IT MADE THE USERS TOO POWERFUL AND HARD TO CONTROL. KNOWN SIDE EFFECTS: RAPID MUSCLE GROWTH, HEIGHT GROWTH, STRENGTH AND AGILITY. ADDED SIDE EFFECTS: HUGE COCK GROWTH, BALL GROWTH, SEMEN GROWTH AND PUBE GROWTH. ONLY TAKE ONCE. DRUG TAKES 14 DAYS TO WORK FULLY. Being shy about his purchase, Jamie ticked a box saying 'ship without label' and didn't mention anything to his family about this. Unfortunately for Jamie, the drink arrived a day when he wasn't there. Day 1 Jess was reading her book when she heard the door and signed for the mysterious parcel, "whats Jamie bought now?" Jess thought. The bottle was a stylish metal flask with a label on the side that just read "NOT FOR WOMEN". "Yeah right" she thought maybe he'd just bought a weird smoothie drink a YouTuber promoted. Jamie loved toxic guru videos. However, when she popped the lid it smelt AMAZING. She couldn't get over how good it smelt. She desperately wanted to put the lid back on knowing Jamie would be home soon, but she decided to give a little taste first. She had a sip, then a gulp, then another gulp, "WHAT AM I DOING" she thought, "JAMIE WILL KILL YOU". But she couldn't stop, it tasted too good. Before she knew what she'd done, she'd drunk the whole bottle. "Oh god, oh god, oh god" she thought after she'd finished. Thinking quickly she hid the bottle away at the bottom of the bin, maybe Jamie would just think it got lost in the mail. Almost immediately after she hidden the bottle she felt a burning sensation like she needed to pee, only her whole body was warm. She went to the toilet but nothing happened except she was getting warmer and warmer in her groin. She decided to feel it, her clit was rock hard and crazy sensitive. She began rubbing it gently, it felt insanely intense, she could feel sensation travelling up her spine. After just a minute of doing this, she came harder then she'd ever done in her life and for the first time ever, she squirted. "What on earth" she thought, "the drink couldn't have done that could it??" Calming down she decided to go back to the sofa and read her book, Jamie might be suspicious if he came home and she wasn't where she was always sat. Jamie came home 30minutes later, unlucky for Jess, Jamie asked immediately "Jess was there a parcel for me today?" "No, did you buy something?" Responded Jess casually. "Jess, don't be a brat. I got a notification on my phone saying you signed for my parcel?" "SHIT" Jess thought. Thinking on her feet she responded not looking up "oh err yeah a bottle might have arrived" Jamie getting more annoyed "where is it then shrimp, I paid a lot of money for that drink?" "Erm, well I may uh, I might have drunk it" said Jess meekly looking up. Jamie looked panic struck. "YOU DID WHAT?!" "I'm sorry, I just meant to smell it, but it smelt so good and... I kind of drunk it all" confessed Jess. "You fucking idiot, what have you done! Girls aren't meant to drink that stuff! you're buying me another one!" Said Jamie bright red with rage. "Yes of course! How much was it?" responded Jess. "My whole fucking inheritance!" Said Jamie now shouting. "WHAT?" Jess said thinking he must be exaggerating. "I spent my whole inheritance on that and you are buying me another" shouted Jamie. "Jamie, I'm so so sorry, but there is no way I'm spending that on a smoothie for you, you should have told me about it, what does it do? Cure cancer?" Jess was in shock, why would Jamie spend so much on a smoothie, was he joking? Then a thought hit her, "what do you mean girls aren't meant to drink this?" "It's a growth drug you dumb bitch! But it's only been tested on men, it probably wont even work on you" Jamie started punching a wall with rage. Jess ran up and tried to stop him causing damage, she grabbed his hand and when he turned they both saw something shocking, they were looking eye to eye. Day 2 Jamie woke up enraged. He'd spent the whole evening bullying his sister and forced her to buy another bottle for him. But even knowing another bottle would arrive in 14 days he'd slept awful. How could his sister of be as tall as him already? Will she get taller? Surely it wont be as effective on women. Jamie would soon get some answers. Not being able to sleep he went to get breakfast. Jamie was sat at the breakfast table waiting to be handed his toast when he heard his mum shriek "OH MY GOD JESS". Expecting to see his 5ft sister Jamie was in utter terror. Jess was now stood at a staggering 6ft. It was utterly bizarre to be looking up at tiny little Jess's face. She was the same hight as the door frame, her limbs were stick thin and poking through her pijama's. Jess was in tears and after explaining everything that happened, their mum was immediately taking Jess to the hospital. Jamie was brought with them. He sat next to Jess in the car and felt like a little child sat next to her. Jess had to wear Jamie's clothes, but him being 5ft and her being 6ft, the clothes were much too small for her tall frame. After waiting they were brought into the GP room, they waited for another minute then in walked the most stunning doctor Jamie had ever seen. Long blond hair, a tight skirt and even though they were hidden well, undeniably large breasts concealed under her shirt and lab coat. "The lab results are in" the doctor began to say in a warm friendly voice "and everything is fine. Jess will need to be brought back in for regular tests, but other than your height everything else is normal", then she looked over at Jamie, pushing her glasses up her nose "that was a very stupid thing you did buying that stuff online, you are lucky your sister wasn't harmed." Day 3 Jess woke up to the same sensation as the day before - that she HAD to masturbate - she slid her hands down to feel her clit when the first thing she noticed was that her pubes were getting way thicker. As she felt lower she felt her clit was huge, it felt like it might be an inch long. Rather than rubbing it as normal she pinched and rubbed it up and down, almost as if she was jerking off. The pleasure kept intensifying until again she came. She then got up and admired herself in the mirror, her body was perfection, she was a slim 6ft goodess, but she had noticed a few extra changes today. First she had indeed grown a thick set of pubes. Next her body was more muscular, no longer as twig like as before. She has a tight set of abs appearing and she could see the faint outline of a bicep on each arm, could her muscles be growing too? She could also see that her clit was poking though her bush, she was a little worried about this, she really didn't want that to keep growing. Day 4 Jamie woke up scared, his sister was definitely looking stronger yesterday, what will she look like today? When he came home from school yesterday he was relieved he was still able to wrestle the TV remote off of Jess, but it had be harder than he expected. Jamies jaw dropped when Jess walked into the kitchen, ducking her head under the doorway. She was wearing one of her old tops - not one of the new ones their mum had bought her - which let her abs poke out below. Her six pack was even thicker than yesterday and her biceps slightly larger. But that wasn't why he was shocked, her breasts were noticeably ... well ... large. Two perky water balloons were jiggling as she moved around the kitchen. Her mum walked in, clearly noticing what Jamie had noticed she said "oh honey, we are going to have to buy you a bra" "Oh yeah" Jess said cupping her new toys, they were slightly more than her hands could handle, "but better wait I can feel they are growing still" "fair enough honey" said their mum, "Jamie could you get me the pan off the top shelf". Jamie walked over tried to reach, he was almost there, straining on his tip toes when Jess came from behind saying "dont worry Mum, I've got it" Jamie felt Jess's hand on his shoulder while Jess's breasts rested gently on the back of his head - the closest he'd come to a woman's... well... anything before. Jess effortlessly picked up the pan and placed it on the counter. "I was getting it" Jamie said annoyed. "Your too short Jamie, you needed a stool" said Jess, patting Jamie gently on the head. Jamie thought he could see his sister smirk, she couldn't be enjoying humiliating him could she? Day 5 Today was Jess's first day back at school after everything had changed. She was terrified how everyone would react. Today when she'd woken up, she was slightly taller and slightly stronger, but her focus was on her growing clit. It was now at 3 inches long flaccid. She didn't want to think it, but it kind of looked like a penis. She would care more, but she was having the best orgasms of her life, she decided she'd wait until she saw the doctor again before saying anything. She reached for her tight white top again today, she saw Jamie looking yesterday and knew it drove him crazy. It fit again, only today it was much tighter, her breasts now filling the fabric and a long line of straining cleavage was running down the v-neck. She couldn't believe how perky they were for the size, when she cupped them they were far more than her hands could hold and much heavier than they looked. Despite their weight they sat beautifully on her cheast. She couldn't wait to go for breakfast, Jess knew her tits drove Jamie crazy yesterday, today they were almost twice as large. She loved humiliating Jamie now. As Jess walked in and pretended not to see Jamie staring at her. Despite not really feeling like it, she reached for a cereal box all the way on the highest shelf - just to demonstrate how easy it was for her. She then made a bowl of cereal twice the size of his and sat on the counter top, resting her new larger butt on the surface. Their mum walked in "Oh good Jess you are up, I was thinking today, I know I usually drive you both in, but I was actually thinking you could both walk in today?" "Are you sure Mum? I thought you said the Brockney Street wasn't safe?" Said Jess. Jamie was confused, this is something he'd wanted to do for years, but their mum wouldn't let him. He hated being dropped off by his mum and pleaded he would be sensible and take care of Jess if they walked, but she never let them. What had changed? "Well it isn't safe" said their mum, while she was busy getting her bits ready for work she continued "but I'm less worried now, just take care of your little brother OK?" Jess saw Jamie turn a bright red and shout "what do you mean little brother? I'm 2 years older than her?!" he walking up to their Mum past Jess. Jess noticed as he passed how funny and kind of cute he was when he was angry now. "Oh sorry Jamie" said there mum sweetly "I just meant you're the smaller sibling is all, your sister is so much bigger and stronger now, so she can protect both you if anything goes wrong, but I'm sure everything will be fine". Jess could not believe how amazing this feeling was. Her big bully of a brother, was now her little brother. She decided to rub this in a little more, by lifting up her arm, flexing her bicep and saying "dont worry mum, I'll protect us". Jess surprised herself with this a bit, she'd never flexed her new biceps before. Even with just a small flex the thing was thicker than Jamies leg, though his legs were very skinny. The bicep itself had noticeable vein running down it and was about the size of an apple. Jess saw Jamie clock the growth and leave the room visibly angry and humiliated. Day 6 Jamie had had the worst day ever yesterday. While no one knew Jess was his sister, he had heard everyone in the school talking about her. Everyone wanted to know who the new girl was, probably not realising she'd been there for years. Jess had tried to hold his hand on the way to school, he was certain she was humiliating him now. He hated walking with her. For most of the walk she walked ahead, her new longer legs meant that she walked faster effortlessly. However when it came to Brockney street a homeless man, visibly high, actually stopped Jamie and was getting very pushy. Jamie could see Jess walking on and panicking he cried out "JESS!". Jess turned, walked back, grabbed Jamie's out reached hand and walked them on. When the homeless man tried it on Jess she effortlessly pushed past him. The second Jamie felt safely away from the homeless man he pulled his hand away. Today he knew if he didn't want her help he would need to stay closer to her, where he was safe. He was about to walk in the kitchen when he heard a knock at the door. It was Jess, she was crouching to look through the doorframe, he tits were now so large they were spilling out under her shirt, large puffy nipples pressed so tight against the white fabric you could see the colour and outlying of them easily. "Sorry Jamie, you know your baggy white hoodie? I was hoping I could borrow it, this was my biggest shirt before" Said jess, intentionally choosing that moment to try and pull the shirt over her breasts, only for them to immediately slide back out from under, "only well, it doesnt quite fit me anymore." Jamie knew which on she meant, it was one he'd gotten for Christmas, but everything about it was too big and even the sleeves would dangle over his hands. He was thinking about saying no, but he didn't want to fight. He went to look for it while Jess walked into the room. "Did you hear?" Jess said "They've asked me to join the weightlifting team at school, which means I can use all the weights for free" "What are you weightlifting for?" Jamie said annoyed "you're already a freak of nature!" "I just want to test my new strength" Jess said flexing her biceps in front of him again. They were huge! In just one day it looks like they might have doubled. Yesterday they were big, but they were more skin on muscle, today they were thick protien cannons, with one almost cable sized vein running down each bicep. "I tried bicep curling for the first time. I'd never done it before so I'm not sure whats good. You used to go to the gym right? What did you used to curl?" Jamie knew full well that all he could curl was the 5kg, he'd managed 10kg but only for 1 rep, but he pretended not to remember. "Ahh well I lifted 30kg, which they said was good, but if I'm being honest I wasn't trying that hard" Jess said smiling, knowing full well that no one in the school could possibly come close to her strength, let alone her skinny 'little' brother. 30KG! This was half his weight! His little 18 year sister, who was 4.5ft a week ago could now lift half his weight with one arm! He found the jumper it was actually heavy for him to lift and way oversized for him, but trying to act calm and handed it to her. She pulled it over her head and as she did her breasts looked like they might almost escape from under the top. He watched as she struggled with the jumper, he could see already it wasn't going to fit her already. But he couldn't help take the opportunity to notice her abs had gotten thicker and more meaty too and 2 more had appeared at the bottom, partially obscured by a thick black pubes now poking out above her joggers. "Jesus Jess don't you shave?" said Jamie without thinking. Jess pulled the jumper off, giving up trying to fit into it. "Err well I actually I was going to tell you, I tried to shave last night with your trimmer and it well, the thing is my pubes are quite thick now and I think your little trimmer couldn't quite handle them, but don't worry, I've bought a new stronger one we can both use, should arrive next week." Jamie was desperate for his smoothie to arrive next week and end this humiliation. Day 7 Today Jess put on a new top her mum bought her, she still had her old top, only there was now no way should could wear it without her aolas poking out from under. The new top fit her snuggly and was much more comfortable and best of all it still had lots of cleavage. She was now a staggering 7ft, her legs would dangle off the end of the bed, she was desperate to go back to school, but today was the day she'd go back to see the Doctor for more tests. She was relieved because as she looked in the mirror, her clit was now most definitely a cock. She wasn't sure but she felt like it was a reasonably large one too. That morning their Mum - who had to go to work - agreed with Jess that Jamie should go with her to the doctor, then Jess could walk them both to school. Jamie was left out of all decision making these days. However Jamie's was a little excited because it meant they got to see the insanely hot doctor again. They were both sat in the Doctor's office in chairs side by side, Jess was looking down at her thick thighs next to Jamies twigs. Jess not thinking wrapped her index finger and her thumb around Jamies bicep and said "look Jamie I can wrap my hand around your whole arm." Jamie shook her off "leave me alone". "Oh dont be stroppy" said Jess. "I'm not being stroppy" said Jamie. "You can do mine?" Jess flexed her bicep in front of Jamie while Jamie tried his hardest not to look. "Why would I try that?" Jamie said annoyed. "Because I will hold your hand all the way to school today if you dont" said Jess in a humorless voice. Jamie knew she was serious and obliged. Seemingly knowing 1 hand wouldn't be enough he reached forward with both. Jamie wrapped his hands around her right arm, Jess could feel Jamie gently squeezing it with his fingers. Jess was shocked as she began to realise both Jamies hands wouldn't even have a chance wrapping around her flexed bicep. Curious Jess began to relax her arms to give Jamie a chance. To Jess's delight Jamie clearly could tell what was going on and began to go red when she did this. Even when Jess's bicep was fully relaxed and with both hands, he still could not fully grasp it. Jess was becoming more and more red by the second, except she could tell he wasn't angry anymore, it was to realisation of how much more powerful she was than him. Rubbing it in and taking pleasure in the moment Jess said "come on Jamie I'm not even tensing anymore", sounding almost sounding disappointed in him. Jess could see Jamie using all his force to get his fingers to touch, but there was almost an inch for him to go when the doctor walked in. "Hi Jamie, Hi J..." She paused looking at Jess, who was almost eye level with the 5ft 10" Doctor sat down. "Hey Doc" said Jess in a friendly voice. The Doctor looked shocked as she said "wow Jess, erm wow! You've grown... Would you err, stand up for me please Jess?" Jess obliged and even though he wasn't asked, Jamie did the same. Jess noticed that Jamie being 5ft barely came to the Doctor's chin, while Jess being over 7ft, meant Jamie barely came up to her tits. In fact, without even trying to humiliation Jamie, Jess would walk into him by mistake sometimes when she moved around the house, ocassionally not even noticing she'd knocked him over at all. The Doctor walked up to Jess and began examining Jess's biceps in curiosity. Jess noticed Jamie staring with extreme jealousy as the Doctor admired and stroked the thick cable like vine running down Jess's Bicep with her thumb. "This is all in one week?" she asked breathlessly arching her neck to look up at 7ft Jess. Jess nodded. As Jess felt the doctors hands on her bicep, she began to feel slightly aroused and notice her nipples begin to get hard. Jess knew it would be almost impossible for Jamie and the Doctor not to notice too. While she didn't care about Jamie, she was a little embarrassed when the Doctor saw them. For the first time in a week she blushed and said "err sorry". The doctor chuckled gently "not at all, it's cold in here, can I feel them?" "Errr, sure" said Jess, unsure what the Doctor meant. The Doctor cupped Jess's beasts gently and shook them, almost as if just to test they were really real. Jess was pretty sure this wasn't an official test. "Incredible" she whispered, then coughed almost as if to wake herself up from a dream. She then stepped back so that she could look up at Jess, pushing her glasses up her nose she asked "erm jess, I was doing research on the drug you drank and has there been err... anything else erm, well ... growing?" Jess looked down and saw Jamie looked completely confused by the question, then looked back up at the Doctors bright blue eyes and thought about the question. "oh yeah she said" and perhaps because she was now so big and so strong, but completely without thinking about Jamie being there she pulled her pants down "my clit has well ... gotten bigger". The Doctor and Jamie both went white as they stared at Jess's flaccid 5 inch meaty cock hung in front of them, complete with balls the size of cream eggs. Jess watched as Jamie stepped back, she was sure it was a big one now, but still unsure on how big, she'd never watched porn and was a virgin. Jess was the first to break the silence "I first just thought my clit was growing, but now I'm pretty sure its a penis, because every time I masturbate it cums", Jess said almost as if this were a normal conversation. "Yes Jess, its definitely a penis" responded the Doctor not looking up and almost sounding impressed, "you might want to warn people before pulling that out in future" she said looking at Jamie who was stood mouth wide open and now so white he looked like he might faint. "You said you can cum?" Said the Doctor now curious looking back at Jess. "Yes" said Jess politely. "Would you mind giving me a sample?" Before waiting for a response she turned her head to Jamie and a said "and Jamie, I will need one from you too". "What?" Said Jamie in a horrified voice. The Doctor turned to look at Jamie straight on, "Look in order to check your sister is healthy we need a sample form her, and if there are any issues it would be good to have someone to compare her sample to" she walked over and picked up 2 cups handing one to Jamie and one to Jess. Jess was confused when the cup was given to her "is this for the cum?" Jess asked. "Yes my love" said the Doctor smiling. "Is... there a bigger one" said Jess. The Doctors smile dropped and Jess thought she could see Jamies heart sink even further. She actually felt her cock twitch at the humiliation he must be feeling. She was pretty sure this cup was a lot more than he could fill, but not her. "Will 2 cups do?" asked the doctor, biting her lip a little eyes not looking away from the cock. >> Switching to Jamie's point of view. Jamie had a hard time producing a sample, he couldn't get his sister's flaccid 5 inch monster out of his mind. Despite this he was rock hard from the vision of the Doctor feeling his sisters bicep. He dreamed of that being his bicep. After a little while he'd managed to cum and walked out. Noticing his sister wasn't done he sat down and looked at the small puddle of cum at the bottom of the cup, on the side of the cup it had lines on it going up to half a pint. There's no way his sister could actually fill this he thought. As he thought about this he was in waited a minute, then 5, then 15. Then finally over an hour later, his sister walked out. What was she doing in there? He soon could guess. "No fucking way" he whispered as out walked his sister WITH the Doctor, except the Doctors hair was messed up, no longer in a perfect tight pony tail and her top was wide open so that you could see her bra and her huge cheast which was dripping in sweat. She was pulling her skirt down and looked like she was having trouble walking. How hard could had Jess fucked her? Then a thought occoured. While the doctor towered above him, she was nothing to Jess, Jess could probably lift the doctor with ease with those huge arms. He hadn't noticed before but he could see the bulge now in his sisters pants, stretching down the skin tight jeans. How did that thing belong to his sister? and had she actually just fucked the doctor? Had his 18 year old sister just lost her virginity before him? Suddenly he realised, his little sister, with that cock, if this had of happened already, this was just the beginning. "Oh hi Jamie" the doctor said politely and breathlessly putting her glasses back on "Thanks for waiting, your sister needed some ... errr... assistance". Then he noticed something else, in the Doctor's right hand were 4 filled cups stacked up, some had visibly overflowed with cum dripping down the outside. His little sister had filled 4 whole cups! Then to Jamies continued shock, another nurse walked out of the room pulling up her scrubs! The nurse walked over to the fountain, drank what must of been a liter of water then collapsed in to a chair near Jamie breathing heavily like she'd just run a marathon. It looked like his little sister had not only had sex, but a threesome! This can not be happening he thought. "Oh is that your sample Jamie! Well done" Jamie almost didn't want to hand it over, the cup had probably 10mls of cum in the bottom. He saw Jess strain her eyes to see if there was actually anything in it. The doctor placed it on the top of the pile and looked over at Jess as said heartedly "looks like we wont get these confused". Jamies heart sunk, for the love of GOD, he needed that smoothie. _ On the way to school Jamie had to listen to how incredible sex with the doctor was. "She just kept saying she'd never had a cock so big!" Jess said happily "and then she called in this other nurse to look and she was the same!" Jamie said nothing as Jess continued. "I cant believe I've never had sex before, it's amazing! She said she'd never cum so much before. have you had sex Jamie?" Jamies heart dropped, he was pretty sure she knew the answer. "You've not had sex have you? Does it bother you that I've had sex before you? It's OK if it does." Jamie said nothing as Jess kept talking. "Admit it Jamie, you were scared when you saw my cock". That was it for Jamie as he foolishly retorted "no I wasn't! Anyway how much can that horse cock of yours really grow, bet you can barely get it errect" Jess smiled, she'd clearly wanted Jamie to ask this. Jess clearly took pleasure in the answer "the Doctor wandered that too" Jess said slowly "she said when she measured it, that it was about 11 inches", for the rest of the day Jamie thought about nothing else. Day 8 Jamie was lying in bed, erect, with a measuring tape. He had the tape next to his 4 inch erect cock, and the tape stretched to 5 inches. Jess's flaccid size. He kept thinking about how thick her flaccid cock would look next to his erect one. He looked over at his wrist and thought it was probably thicker than that too. Then he pulled the tape out longer, slowly extending it to the supposedly fully erect 11 inches. His little sister's beast was almost 3 times his and closer to the length of his thigh than his cock. He stared at the tape against his cock, Jess was basically a god next to him. He shamefully came to the thought of his sister fucking the absolute shit out of the Doctor and nurse, then went to the bathroom to clean up. Jess was walking out as he walked up. As always she had the towel tightly wrapped around her tits, but towel which used to drap along the floor now couldn't even fully cover her cock, the tip of which was poking out below. Jess who was un aware - not that she cared - did not see Jamie walking around beneath her and just walked on to her bedroom. When Jamie entered the bathroom the small bin which had been emptied yesterday, was now filled to the top with thick black pubes. Clearly the new trimmer had arrived. Jamie went to pick it up the device - as it had been a while since he'd had a trim - to his shock it was much heaver and bigger than he'd expected. It took 2 hands just to hold it comfortably. Jamie noticed that the thing was so powerful it needed mains power to run. He couldn't help but imagine how easy it must be for his sister to use, this would be nothing for her giant hands and new strength to use. Jamie curious why Jess needed such a device placed it down and picked up a clump of her pubes. The clump was huge and thick, each pube resembled wires more than actually hair. He then tried to pull the clump apart, but couldnt. He pulled harder and harder but it barely budged, even with all his strength it was useless. Then it hit him, he could no longer even win a fight against Jess's pubes. Staring at the huge heavy clump of hair in his hands he was now sure there was not a single part of his sister her was stronger than. He picked up the trimmer again and slowly slid on the power switch and imidiately dropped it in terror, the thing was a practically a hedge trimmer! He was sure that if he was to use that on his cock, it would be more likely to cut his cock off then trim his pubes. He decided to leave it and buy his own smaller trimmer and hide it from his sister. Again he thought about how badly he needed that smoothie. _ Word at school had spread about his sisters 'package' too and that she was his sister. At first he enjoyed the attention until it was pretty clear they just wanted to meet Jess. Despite his sister being 2 years below him girls in his class were begging to be introduced. "Hey Jamie" said the insanely hot Emily from his school house, Emily had never once even looked at him before, "you're the brother of that Jess girl right?" Jamie couldn't believe Emily was even talking to him "err yeah I guess". "Well" Emily started, getting right to the point "would you mind inviting her to my house party tomorrow night, my parents are away, and well, you can come too I guess, but you have to bring Jess". Then after saying just that, she handed him a piece of paper with her address on it and the date and walked off. Day 9 Jess was again standing in front of her bedroom mirror wondering what to wear. Her head was now almost touching the cealing, her cock swinging 6 inches from her thick bush, which despite having been trimmed yesterday, was already starting to grow back thick and fast. Se wondered why Jamie had invited her along to this party tonight even though he seemed to hate her these days. She was thinking it was probably that slut Emily from his class. Only 2 days had passed since Jess's secret got out and Emily had approached her twice. Jess already had her hands on bigger prizes however, the gym teacher Alice had taken a special interest in her. Alice had had suspcions earlier as she'd seen the bulge through Jess's gym gear. Alice was a 30 year old smoking hottie who was always complaining about her shit ass lazy boyfriend. However, until yesterday, Alice hadn't mentioned how bad her boyfriend was in bed, now it's all she could talk about. "I just dont feel satisfied by him tbh", "he cant even get me pregnant" and "tbh - and I cant believe I'm saying this to a pupil, but I really just want to be fucked hard". Tomorrow she was going to give Alice what she wanted. She slid on the only jeans that fit, and with effort slid a white v-neck top over her huge tits and left to walk Jamie to the party. While on their way out their Mum stopped them "wait! Have a great time at the party and Jess look out for your li-big brother. Dont let anyone hurt him OK". "What are you saying Mum? I'm should be looking out for Jess?" Said Jamie, but even he knew that in reality, Jess really was watching over him. Jess just ignored Jamie "dont worry Mum I will keep him safe". On the way to the party they went to get booze. Jamie went first, but got rejected buying 20 light beers because they assumed his actualy valid 20 year old ID was fake. So Jess then went in and got served instantly, she came out carrying two 20 bottle beer crates of extra strong ales under each arm. "What are you doing?" protested Jamie "I can't drink all that?" "Relax" responded Jess, "I bought them and I hate that light shit. Anyway most of these are for me, you'll only need a couple". "Just because your big doesnt mean you can out drink me, I'm still a guy" said jamie clearly annoyed. Jess was ready for this though when she responded "I'm over 7ft Jamie and your 5ft. I barely see you when I'm walking round the house and I am willing to bet my cock is thicker than your arms now. I doubt you could even drink half as much as me". Jamie said nothing. When they arrived, Jess made sure everyone knew that she got served while little Jamie didn't. Jess watched as Jamie went to get a drink when Emily came over. Emily was looking better than Jess expected, she was wearing a bra-like top and jean shorts she hadn't notice before how great her tits looked, which were usually hidden under a school shirt. Things were a bit of a blur, but soon Jess and Emily were sat on a sofa making out and chatting amoungst a busy room full of people. Jess caught Jamie walking by and catching a glimpses of Emily - the hottest girl in his class - gently and knowingly resting her hand on Jess's cock bulge. Emily was getting Jess drink after drink, but Jess was barely feeling drunk. "You got anything stronger?" whispered Jess in Emily's ear. "Stronger? You've had 30 beers, you should be dead!" responded Emily getting up. She returned with a big bottle of whiskey just as Jamie walked over. Jamie had been quitely watching as her sister drank 30 of their 40 beers, Jamie had had 4 and was already wasted. "Give me some Emily" said Jamie drunkenly. "No way you are wasted" said Emily, but just as she said that he grabbed the bottle. Just before he chugged it, he wisely chose to pour out a small shot into a glass before downing it. This didn't help though, as he immediately threw up on Emily's carpet in front of everyone. "What the fuck Jamie!" cried Emily. "Aww dont get angry at him Emily, he's only small, this like a pint glass to him" she said picking up the small shot glass, looking straight at Emily and not even acknowledging him. Jamie clearly drunk and angry wanted to prove himself, "Shut up! I'm not a kid. I can drink it. I was just surprised by the taste. Give it to me again!" He went to grab the bottle, but Jess got to it first, she barely noticed him clinging to it as she pulled the bottle towards her with Jamie attached. Jamie let got before she could lift him up with it. 'Smart move Jamie' she thought as she sniffed the bottle, then to Jamie's and the room's surprise, she began to drink 70% whiskey straight from the bottle. Jess expected this to go badly, but she couldn't actually sit and watch Jamie drink and embarrass himself anymore. To her shock however, she really enjoyed the first gulp. Then the second. Then the third. Before she knew it, she was drinking the whole bottle to a cheering room. Everyone but Jamie was chanting "We like to drink with Jess, because Jess is our mate, and when we drink with Jess, she downs it all in 8! 8! 7! 6!" But before they could get to 5, the bottle was finished, she placed the bottle on the table as the room cheered in admiration. "Holy shit Jess! are you ok?!" shouted Emily. "Fuck yeah that was amazing!" said Jess enthusiatically and leant in to kiss her, Jess could feel her huge tongue filling Emily's mouth. Jess then felt Emily's hand slide up her top, Emily's small hands could barely grab Jess's huge aola's. Jess leant back and said with a small feminine burp "I'm deffinately feeling a little drunk now". Emily leant in and whispered in Jess's ear "how about we go up stairs and lie down". Jess was pretty happy with this idea and left Jamie sat on the sofa looking annoyed but also about to pass out. As they walked up Jess caught the envious eyes of all the men watching her. Which to her surprise, made her cock begin to twitch like crazy. She wondered if there was a signle man here that was bigger than her beast? Almost before the door was shut, Emily was already undressing, pulling off her shorts, revealing no underwear. Jess pulled off her top setting her tits free, she began to pull her jeans down when Emily stopped her to ask if she could do it. Jess nodded. Emily pulled off the top button, then the second, then the third. Emily could now see the base of the cock and whispered "holy shit", Jess closed her eyes as she felt Emilys tiny hands wrap around the base and with all her strength Emily began to pull the cock free from Jess's skin tight jeans. Jess felt her cock break free from its tight prison and instantly begin to swell. "I cant wrap my hand around it" said Emily almost in fear, Jess looked down at her still mostly flaccid cock to see that while Emily had mostly gotten her hands around it, should could indeed not fully grasp it. "Is that bad" she asked geniunely. "Its amazing" said Emily not looking up and leaning in to kiss it gently. Jess felt it fill with blood. Emily took turns stroking Jess's cock with both hands, cupping her balls and rubbing her own clit. Emily couldn't stop talking, "fuck its gets bigger?", "Its still fucking growing!" and "Jesus christ, it bigger than my head". Emily held her face against the now rock hard cock, it wasnt just bigger is was a safe few inches bigger. Jess pulled a condom out her pocket "I err stole this from Jamie, I doubt he will be needing it any time soon". Emily let out a loud "HA" then continued "you think that will fit this?" she said shaking Jess cock and smaking it against her head. "It wont? Can't they like - stretch a lot?" Jess asked. "Everything has limits Jess, but sure we can try" said Emily, pulling out the condom and attempting the place it on Jess's cock. Jess could see what Emily meant. It wasnt so much just the length, more the thickness. Emily as gently as posible managed to start getting the condom over the tip of Jess cock, but again Emily's tiny hands on her beast made her twitch. A small glob of precum slipped out, filling the condom instantly. "Did you cum?" asked Emily confused. "No that err just happens in the build up" said Jess slightly embarrsed, blushing again. "You mean to say that this is pre-cum" holding the small water ballon next to her head. Jess again nodded. Emily excited laid on the bed, Jess pulled off her jeans and walked over. She rested her cock on Emilys chest as Emily wrapped her legs around Jess's waist. Jess watched as Emily's two hands played curiously with her cock. Jess was comparing her 11 inch fully erect cock to Emily's torso. It stretched from Emily's pussy, past her belly button and almost touching her tits. Then Emily said exactly what Jess was thinking "I wonder if it will fit". Jess slid in gently, the tip was the hardest bit, but it helped that Emily was literally dripping wet. To start with Jess went as gently as possible, but found with every inch she gave Emily, Emily wanted just a little more until eventually Jess was fucking Emily's brains out. To start with, she wanted to be quiet, but she was losing all sense of control. Now she wanted the whole house to feel her cum. She fucked Emily so hard it made the walls shake. Pictures were falling down and lampshades were swinging. Emily was crying tears of pleasure, every time Emily came Jess felt her whole body cum against her shaft, she stopped counting after 7. Emily soon had no strength left in her, she was willing to just be used by Jess, a flesh light for Jess's pleasure. When Jess was finally done they both lay together for a bit in silence, Emily's hand feeling the deep groves of Jess's 8 pack. When Emily feel asleep Jess got up and went downstairs, she saw Jamie passed out not far from where she'd last seen him. She picked him up and carried him home in her arms. Day 10 Jamie woke up with a splitting headache and patchy memories of the night before. The last thing he remembered was vomitting on the floor in front of everyone trying to impress Emily, then falling asleep on the sofa. He rememberred waking up at one point during what he though... was there an earth quake? The whole house was shaking, a photo had just fallen of the wall and the lamp shade above him was swaying like crazy. Was he just really drunk? What was going on? Was everyone OK? Then her rememberred more, that some of the people were laughing, while some of the guys looked uncomfortable... why did they look worried. Then her remembered what he heard, the loud deep grunts of his sister and the high pitch cries of Emily. Almost the enitre party it seemed had stopped to listen. 30 people sitting in a silent room as the walls swayed. A few of the girls seemed to get off on this and were now making out with the boyfriends, others just looked shocked. Jamie wanted to leave but he was still to drunk and fell back to sleep. But wait, if he didn't leave, how was he in his bed? and even though he was under covers he could tell he was now nude. How was he now naked?! "Morning sleepy head" Jess walked herself in and leant in the doorway. She'd clearly just been for a run as she was glistining in sweat and was wearing her tight yoga pants and white crop top which were way too tight for her. Her cock looked as if it had grown since he'd last seen it and was pressed so tight against the thin fabric that the thick viens were actually visible through the pants. While her tits, which were now bigger than his head were both poking out from under her top. "How... how did I get back here, and how am I naked" he asked rubbing his head. "Well I brought you home, but you got naked yourself" said Jess. "why, why did I do that" asked Jamie. "You wanted to compare cocks" said Jess. "I WHAT!" Jamie said horrified. "I tried to say no but you started pulling it out and I couldn't stop you" said Jess. Jamie's heart was sinking as he remembered the events. Then Jess continued "you pulled out your little 3 inch cock said this is a real cock because you were born a guy, and mine is a fake cock" "oh my god, oh my god, oh my god...." said Jamie out loud now remembering. Then Jess walked up to the end of the bed and continued to talk "then I pulled out this" and to Jamies horror Jess pulled out the thickest 6 inch cock he'd ever seen from her Yoga pants. "Jess what are you doing" cried Jamie, not being about to look at Jess, fixated on the threat in front of him. Jess ignored Jamie "and said Emily didn't seem to care that my fat beast was fake when I fucked her for 4 hours last night." She swayed and it audibly slapped her inner thighs. Jamie was horried, that horse cock had already fucked 3 people - that he knew of - and it was still growing. "Then I said your little 'guy cock' wouldn't be a fair comparrison, so I held it against your bicep" Jess said, using air quotes when saying 'guy cock' for added humiliation. The memory hit him instantly, him tensing his bicep while Jess's held her cock against it, the realisation that his little sisters cock was actually bigger than his arm. Not even a little bit bigger. Jamie would actually wish his biceps were as thick and vieny as her cock. "I said you probably couldn't beat my cock in an arm wrestle haha" she grabbed her cock when she said this and swung it in front of him, the sound of the slap when it her thigh was like a porter house stake smaking a chopping board. "You... you weighed it" Jamie said rememberring. "Oh so you do remember haha" she said - her cock giving a visible twitch. Jamie wondered if it grew as she continued talking "yeah I asked how much do you even lift with those twig arms, you said 5kg, and we put my cock on the kitchen scales and it was 6kg! You basically cant even lift my flaccid cock." "Why are you doing this?" Jamie asked. "You were always been so mean to me. Even when I tried to help you you were mean, you just could handle your little sister helping you. All I wanted was a friend and you were never there for me. Well I'm not your little sister anymore. I can cum more in one go than you could carry with 1 arm. The gym at school had to special order me weights, I can bicep curl 60kg each arm, you know what the means right? If I wanted I could curl your little twig body with 1 arm. I've eaten breakfasts bigger than your now." Jess was clearly enjoying this speach because as she spoke her cock pulsing like crazy and with each pulse was visibly growing in size, getting harder and harder. When she stopped talking it must have been 9 inches, now touching his bed sheets. "Jess what are your doing" said Jamie scared. "So you dont remember everything?" said Jess smiling, "You bet me my cock wasn't bigger than your bicep, and I said if I won, I got to compare my cock to your head, like I did with Emily last night. Dont your remember? Maybe not as you fell asleep." Jess began to pull the covers off Jamie. "No, no I didn't agree to this" Jamie protested "Muuuuuuuum!!". "Mum is out Jamie, and you deffinately did, I remember you being very confident" Jess began to pull the covers off of Jamie, revealing his skinny naked body and erect 4 inch cock, "oh are you enjoying this Jamie, do you like being humiliated by me? Is that as big as it gets" Jamie jumped up and tried to sprint for the door. With no effort Jess grabbed his arm and threw him against the wall. Jamie felt Jess's two large hands on both his shoulders, he tried to pull them off. The hands were still clearly feminine, just huge and covering his whole should blades. Jaime couldn't move, her fully flaccid cock had been 6kg, but now at 10 inches it weighed much much more, holding him tightly in place against the wall. Then Jess said "HOLD IT" so loud and so assertively, it was akin to her using 'the voice' from Dune. Jamie did as she said, if he couldn't avoid this he might as well end it quickly. It took both his hands to hold it to his head, he didnt know what pussy smelt like, but he was sure that's what it reacked of. His skinny arms were bulking at the weight of it he felt it grow what felt like another 2 inches, its erect weight was easily 15kg. He wouldn't be able to do this for long. "haha your fingers can't even wrap around my cock, let alone these" she lifted and flexed her huge biceps. A few seconds in and Jamie was already sweating from holding the cock, he was so focused trying not to show he couldn't handle the wieght of it, that he didn't notice his sister pull out her phone. Jess went "cheeeeese" and just as he looked up he saw the flash. Jamie dropped the cock but it was too late. "Delete it" Jamie shouted. "No way" said Jess, "this was part of the deal. Anyway dont worry, I wont send it to anyone, only Emily wants to see it. She's a freak, she wanted to see if my cock was twice the size of your head. Now I have this photo, we know it is." "No dont show it to Emily! I'll do anything!" said Jamie not thinking. "Anything?" asked Jess, grabbing her cock gently and thinking. Not even Jess's huge hands could make her cock look small as she began to stroke it slowly. "Yes anything, please delete that photo" begged Jamie. "OK, OK, well since my beast is rock hard" she said holding her huge 13 inch cock "and since your little lipstick is hard, I want to see something" Jamie said nothing as Jess walked up to him "I want to see how much more I can cum vs. you." Jamie hated this idea, but he wanted the photo deleted more than anything and agreed. Jess bent down grabbed Jamie's hand and walked him to the bathroom where the two began jacking off while Jess teased Jamie. "What are you thinking about?" she said while performing long strokes her own cock "me fucking the doctor again? You know you told me a bout that last night too, that you think about me fucking when you masturbate. You said it while I carried your home in my big arms. I think you wanted me to know. Are you thinking about fucking Emily with this beast until the room shook." Jamie watched as a large glob of cum dropped from Jess's cock, it was more cum than he had ever seen! But at least she was done before him right? Jamie then came right after Jess, to his humiliation, the taunting from Jess actually made him cum faster. "Holy fuck" Jess continued "are you done already little bro? You know I think you like being humiliated by me and my monster." Jess was still stroking the tip of her cock, although now a little faster. "What do you mean? You came before me? That wasn't even that much cum. I though you could cum pints? Wait why are your still masturbating?" said Jamie confused. "Haha Emily and the Doctor were confused by that" said Jess "that's just my pre-cum". WHAT thought Jamie, Jess's precum was more than he could produce in a week, no a month! "This is me cuming..." Jess said, although it took a few moments for anything to happen. Her thighs began shaking first, then the room shook and then all a sudden he felt Jess's large hand under his arm and without even slowing down, Jess lifted him onto her cock. To Jamies continued shock, he was now sat a foot off the floor lifted only by Jess's burning hot beast. Jamie feeling himself falling forward grabbed onto it with both hands as not to fall forward into the firing line. He began to feel all the muscles surronding him swell and tense. Jamie had thought the cock had been hard when he landed on it, but as climax arroached it was swelling to knew limits before his very eyes. The skin was being streched tight as the cock itself became so hard it felt like steel! Jess clearly hadn't measured herself at climax as the cock under him was deffinately larger than 15 inches and it was now so thick and hard that he barely needed to hold on, it was like sitting on a steel bench. There was a calm before the storm for just a couple of seconds giving Jamie a chance to look down at what he was sat on. There was a vien running down the top centre of his little sisters cock that was as thick as his entire 4 inch erect penis. Both her hands were by her sides, he knew there was nothing but her cock holding him in the air. There was an unblieveable amount of power in his sister now. Then finally, after a couple of seconds which felt like was an eternity - it burst like a fire hose. Hot jet's of cum fired into the toilet. Jess let out a low grunt as it happened, like something a bear would make. This was more than any cum experience he had had, Jess would cum with her whole body. The whole room couldn't help but feel her cum. After there intial burst she would have these surges, Jamie was again needing to cling for dear life as the cock under him bucked and bucked again. He wondered if Jess could even feel him on here. Her muscles had swelled to such intensity that he was like a bug to her. To Jamies horror, the toilet in front of him was actually filling up and he was worried it would over flow, but as it got to rim Jess finally began to slow. The room shook as Jess stepped back, smacked against the back wall. With this Jamie fell to the floor. Jess was breathing deeply her abs were exanding and contracting from her huge deep breaths she was making. Jamie got on his knees and stared at the cum filled toilet in front of him. Jamie now agreed with Jess, even with both arms he could not carry just one of her loads. Something about the overwhelming experience of humiliation had him convinced his sister was now a god. A drip of Jess's cum landed on his shoulder, it was thicker than his arm. He turned around and stood up slowly to see his 7ft 18 year old goddess of a sister breathing deeply above him. He was stood in direct eye line with her belly button. The bush beneath was so thick and large, had they been on him you wouldn't of been able to see his cock. Jess's now softening beast however dropped from the bush proudly, and huge from his chin to his belly button. "If I had that cock" though Jamie "I wouldn't even be able to walk" he looked down at his skinny legs then back to the thick beast. Jamie felt so small in front of it. Jess's cock had more strength, more power than he possed in his whole body. He then picked up his towel and began to clean it, a small part of himself deep inside was screaming, but there was nothing he could do. He felt so small in front of her it felt natural to serve her. Jess looked down confused "fuck Jamie, I actually think I forgot you were there? Did you stay on my cock the hole time? That's impressive haha why are you cleaning my dick?" "Errr, I'm sorry Jess" Jamie said waking up. Why was he doing this?! Why was he saying sorry? "Jesus Jamie, I'm not sure I realised how much bigger I am than you?" Jess then got down on one knee to look at him eye to eye, the way you would a child. She pulled off her shirt, setting free her huge tits and placed the crop top on Jamie where it became more like a dress. Then she picked him up and carried him back to bed. While lying in bed he gradually recovered and rememberred than he would soon be that size too. All he could hope for was that his smoothie would arrive in just a few days. Day 11 Jess was worried, in first period she'd been told that she had to report to the principles office. She was pretty sure it might be because after Gym class yesterday she stayed back and fucked Alice for 3 hours instead of going to classes. But maybe Jamie had complained about the fact that even though she promised to delete the photo of her pathetic brother holding up a meaty cock twice the size of his head, she'd not mentioned anything about not sending it to Emily first... Or maybe they were worried when Emily came in yesterday looking 3 months pregnant with no explanation. Anyway, all her worries were put aside when she saw the principle. Excited she rushed home to tell mum everything, only she had to wait as there mum was already consoling Jamie over something. After waiting a little while Jess walked in and asked "whats going on?" Jamie and their mum were sat at the table "Well, Jamie's is not getting very good grades and errr.. well he is being held back a year" She stood next to jamie so that her right inner thigh was in line with his eye sight, the inner thigh where her 6inch cock was visible, as she saw him glance at it she said "oh, ermmm sorry Jamie" she couldn't beleive this, this was going to be so humilating. "Did you want to tell us something, why did you see the principle after school? are you being held back too" Asked their mum, Jamie looked up at Jess in hope that she was about to deliver some equally bad news. "Err no not exactly, I've actually over performed, and well I didn't tell you this, but I applied to some universities... and well, I've been accepted!" she saw her brother turn white again at the news his little sister will be going to uni and he'd be stuck in school. "Oh Jess thats great news" said their Mum "also the Doctor called, she said she doesn't need any more tests, but she wants to see you again for another sample, said you'd know what that means." Day 12 Jamie didn't know why he was going into school now, he was only going to have to repeat the whole year again. He was sat in first period, when he saw a now-pregnant looking Emily walking in with her two friends, only one of them also looked pregnant now, as well as his Gym teacher. He's was pretty sure he knew why. Just 2 days now until he had his own smoothie and he could become a god too like his little sister, 2 long days. He wasn't sure why his sister was being such a bitch, when she knew he'd soon have a smoothie of his own, maybe she was just enjoying it while it lasts. Emily walked up to him after class, she enjoyed humiliating him too now. "How's it feel jamie know you cant even lift your sisters cock? I can't believe its twice the size of your head, that means your head can probably fit in my pussy haha. It's bigger than your arms too isn't it! I can wrap my fingers round your arm see, I can't even wrap them around Jess's cock when its flaccid. When Jess lifts me its like a weigh nothing, she can almost lift me with just her cock. You're about a foot shorter than me, and skinnier too, I reckon it would lift you easy. Her tits are bigger than your head. Last night she fucked 3 of us for 7 hours. Have you even had sex yet?" This went on and on. When he threatened her with anything she threatened to send the photo around the whole school, that was enough to shut him up. "Also I heard you're getting held back, I am too! So dont worry, I'll be visiting your sister lots at uni and telling you all about it" she said to Jamies further distress. Another year was bad enough, but another year with Emily humiliating him was worse. When Jamie went to gym Jess was in the class too, she'd dont all her exams early and so now mostly worked out. For some reason - and again he knew why - Alice the Gym teacher was looking more pregnant than yesterday and wasn't getting up from her desk, she just told the class to do what they want as she eye'd Jess. Jamie tried to stay away from Jess, especially when he could see the cock swingin freely in the track pants. He could see now that she was lifting 70kg on each arm, she wasn't lieing about being able to lift him then, but she might of undersold how easy this would be for her. Even though her arms were big, he knew this was more than most muscular people could even squat, there was something about the drug that made her unusually strong for her size. Which is probably why her cock weighed so much too. When Jess worked out Jamie noticed she swelled up more than usual too, her muscles would become more defined and the viens thicken. But not only this, she must of found it... pleasurable. Her nipples which were normally huge - even for the size of hetr tits - looked rock hard. She was wearing a loose fitting crop to hoodie, so that when she beant over the underboob was on full display. But Jamie notice notice something new today too, on her right nipple was a large and visible piercing. Jaime getting a little arounds at the sight of his sisters huge tits with a nipple piercing decided to take his energy out on his work out, He decided that because he hadn't worked out in a while, he'd use the bench press machine - and since he was just warming up - he'd start just bench pressing the bar. Only he must have misjudged how long he hadnt worked out, because the bar instantly fell to his chest and he couldnt lift it. He must of been there a full minute before Jess walked over "need some help little brother" she stood over him, ignoring the cock pressed against his head, he looked right up her hoodie at her huge underboob, he didnt know boobs could be so large and so perky. The Nipples were pushing the hoodie out further and he caught a glimpse of the large metal hoop. "erm, yes" he said trying to sound calm. Slowly and intentionally she bent over, giving him an even better view of her tits as she lifted the bar with just one finger. After he got up she handed him some 2kg dumb bells and said "I think you should probably start with these and work up to this brother." What was worse was she wasn't trying to humilate him, she meant it. She hugged him squishing her head against her tits, Emily was wrong, Jess's tits weren't as big as his head, they were definately bigger and heavier too. "I need to finish my work out, I'd ask you to spot me but I think you'd die. Tell mum I wont be home tonight, the principle has invited me over." Day 13 Jess woke up and looked down at Amanda - known to everyone else as Principle - lying on her huge bicep. On the other side, Alice. Though alice looked asleep she was knowingly feeling the contours of Jess's abs. Jess couldn't believe the week she'd had. She could no longer go 12 hours without fucking someone. Not only because she needed the release, but literally women would beg her everywhere she went. It was getting too easy too humilate Jamie now too, in fact, she was actually trying not to but couldn't help herself. The other day she was on the floor looking for her keys and she accidentally lifted the whole sofa with him sat on it. She was pittying him until she rememberred his face in the doctors office when he saw her cock for the first time. How good it felt to be so dominant over someone that had been such an asshole of for so long. Then she rememberred him trying to hold her cock, he was clearly trying to hide how heavy it was, but he was literally shaking and sweating under the weight. It was this thought and the filling of Amandas hand gently feeling towards the base of her penis that caused 'the beast' to wake up. It was at this moment Amanda's husband walked in. "WHAT THE FUCK AMANDA YOU BITCH" he screamed. "You shouldn't have fucked your secratary Phil" Said Amanda not even looking at her husband. In fact only Jess was looking at him, enjoying every second of this. "So because I fucked 1 woman, you'd thought fuck 2 women with that silly strap on?" Phil was pointing to the growing tent under the bedding. Jess knew exactly where this was going. "Not exactly" said Amanda beginning to kiss Jess's neck. "Phil, maybe you should sit down, you might enjoy the show" said Jess calmly. "Why dont you shut up you silly bitch, and while your at it, take that silly toy of yours off!" as he said this he ripped of the sheet revealing Jess's now 13 inch member at full mast. Phil stood back eyes wide holding the sheet like a child with a blanket. "SIT DOWN PHIL" said Amanda. Maybe it was shock of his usually quiet wife telling him what to do, or the sight of the huge woman and her giant cock, but he did as his wife said and sat on the chair at the end of the bed. "Good boy, now get naked", to everyones satisfaction, he obliged. He was a portly man, who had clearly married someone way to hot for him. He sat with his shameful 3 inch flacid cock between his legs as his wife and some other lady he recognised as also working at the school began kissing the giant pole. Jess watched the mans faces as she felt 4 hands and 2 lips gently pleasuring her cock. Jess wanted to tear this mans world apart. Jess lifted Alice onto her face and began licking her out with her huge tunge, Alice was instantly trembling in pleasure. This left only one seat for Phil's wife. To phil's horror Amanda needed no instruction and she began to lower herself on to the giant twitching cock. "wha.. what are you doing to my wife" cried Phil gently. "What you should have done a long time ago" said Jess and with that, she did something she'd wanted to do for a while, rather than ease in gently, she could feel Amanda was wet and due to a couple of kids, slightly loser than others she had fucked, so she slammed it all in one go. "FUUUUUUCK" screamed Amanda as the 200kg goddes started slamming into her pussy. Phil shot up to help his wife, Jess only meant to shove him off but accidentally she kicked him across the room with shocking force. The room was huge and he flew back like a bullet until he smacked against the back wall and was actually knocked fully out. Amanda was going through so much pleasure she could barely notice what was going on. Jess was checking every so often if Phil was alive. After 15-30 minutes she lifted Alice's pussy off her face to looked down to Phil who was now starting to stir "Ahh you're alive! Just in time!" "Phil stay the fuck away I'm fiiiiiiii-uuuuuck! Jess ignore the tiny cock prick and just fuuuuuuucking finish, I cant cum anymore" cried Amanda. Jess had never experienced this before but Amanda had been cumming continuously the entire time Phil was passed out. From the moment her cock entered she had been cumming. But she'd been saving her finale for when Phil woke up. Jess threw Alice to the side and focused on Amanda. Alice fell over like a rag doll, passed out from the pleasure of Jess's tonge inside her. Jess then stood up as if Amanda weighed nothing, Amanda was holding tight to Jess as she stood, however Jess could feel her cock was doing most of supporting. Jess placed both her large hands on Amanda's waist gently before grabbing harder. Jess began to lift Amanda up in the air the full length of her cock before slamming her back down. Then again, and again. Amanda weighed nothing to Jess. "Use me Jess ahhhhh fucking use me, finish inside my, I'm your fucking cock sleeve" cried out Amanda clinging to Jess huge hands. Jess saw Phil begin to stand he looked about 5ft 5' - a bit bigger than Jamie - she must have been almost 8ft now. She was big earlier but now she was cuming she was a bulging raging beast and grunting like an animal, it was hard for her to know for sure, but she was pretty sure her cock swelled even more when she was right about to cum, and Phil was going to get a front row seat. Then it happened. Jess came hard. She made sure she got a few heavy loads into Amanda before pulling out and letting the thick ropes fly 4ft across the room, coating Phil. However she may have misjudged how awake he was. Large amounts of Jess's cum were - unaware to Jess - going into Phil's mouth, he tried to swallow but it was too thick, Phil later swore he could feel the actual sperm moving in his stomach. Jess began to hear Phil choking on her ropes, but didnt care. When Jess finally stopped she realised that Phil nose and mouth were blocked and he couldn't breath. She woke up Amanda who, still waking up from the please, rushed to help her husband. "Come on Phil, cough, cough. good boy little more". Finally with Amandas help he got most of it out and could breath again, when he stood up he was covered in Jess's cum. Jess saw Phil look discustedly at Amandas pregnant cum filled belly. She stood above him "you ever cheat on Amanda again Phil, I'm coming back." Day 14 Jamie woke up exicted, today was the day! He had a plan, he would say he was sick to his mum and stay at home. There was no way he was going to risk missing that parcel this time. He waited by the window for hours looking for the post man. He did not eat or drink or go to the loo, but no one came. Hours passed and eventually he was watching his 8ft sister walk up the drive, either she'd been to the gym or she'd just fucked someone, but she was in her swollen state. She swung through the doorway. "Hey brother, why are you waiting by the door?" she said with a knowing grin. "My smoothie was meant to arrive today, I've been waiting for it for hours" "Oh haha that arrived like two weeks ago" Jess said laughing "I paid for next day delivery". "What? You could do that? Where is it?" Said Jamie in a panic. She sat down wide legged in the chair, revealing no underwear under her short skirt, 7 inch flaccid cock dropping down the cushion, "I was thinking, do I really want my little brat of a brother growing huge muscles and bullying me again" she said with a smirk "so today I took it to school and gave it to Emily"
