Emily woke up feeling horny as hell. This wasn't particularly abnormal for her, but it somehow felt different than the other times she woke up like this. The feeling was stronger, more intimate and more profound than ever before. Having a medical condition that messed with her puberty surely felt weird sometimes. To be honest, puberty hasn't been very kind to her: she was 18 years old now and felt like the only girl in her school without breasts. She was just as skinny as she had always been and had only now reached 4’5’’ in height, making her the shortest girl in her class. She frequently gets frustrated with having the worst parts of puberty but none of the best, specifically the woman-specific physical changes that seem to avoid her. She felt hot as hell. Her hands were wandering all over her body as a result of her horniness, first down her flat chest and then caressing her tummy as she got more turned on with every touch. She felt an odd tingling in her panties that slowly drew her hand closer to them. As she gently rubbed her panties she started to sweat while her hand seemed to instinctively want to investigate the tingling on its own. She started touching her naughty parts with more confidence. She stopped suddenly, opened her eyes and gasped. She couldn’t believe what she was seeing. She now had a small dick where her clit was supposed to be. “What? How is this possible?” she said to herself as she touched the small member with shock. It seemed to have replaced her clit completely, even though her pussy was in still in its place.

She was having a hard time even believing this could be real. It was kinda cute though, so small and sensitive. She touched it again, squeezed it and even gave it a few strokes. The peeling of her foreskin felt pretty good. Her small cockhead was now on full display. She played with the cute head a little bit. It was pretty sensitive, even more than her pussy. She then noticed the small pair of balls below. She tried to relax herself and think positively, but to no avail. She felt like a freak. “Why can’t I just be tall and beautiful like everyone else?” she said as her eyes started to tear up. “Why is this happening to me?!” she continued as she looked at her new cock. She then noticed that her small cock was getting hard. Emily then remembered the time she caught her brother masturbating in his room. It was beginning to look just like his cock, only much smaller. She was still horny and her cock felt better the harder it became. With tears in her eyes, she started touching herself like a little pervert.

She played with it and it continued to grow. It became longer and thicker the more she used her tiny hands on it, eventually stopping at about 3 inches in length. It felt really good to play with it like this. Her cock was now fully erect and shaking slightly with excitement. She couldn’t stop playing with it. It felt so natural to stroke her cock, even though she found out about mere minutes ago. She finally found the courage to put both her hands around it and begin stroking hard, just like her brother. The first stroke felt good and the second one felt even better. The third felt like a short trip to paradise. She began to moan and her breaths became heavier while she continued to stroke her hard dick. She shifted her hips up as she lay on her back, involuntarily thrusting into the air as she shamelessly jerked off. The pleasure was growing the faster she moved her tiny hands. It only took her a little over a minute to have an orgasm. Her small cock came vigorously, producing a tiny amount of sperm that landed on her tummy. Her heart was beating very hard. She couldn’t believe she just had an orgasm from her cock and not her pussy. The intense pleasure she got from her new girl-cock was simply mind-breaking. She felt lewd. She felt dirty. But the whole experience was insanely pleasurable. This pleasure lingered for a while, spreading throughout her petite body quickly, making her shiver from head to toe for a few moments after her ejaculation.

Emily quickly got up and ran to the bathroom, careful to not let her cock slip out of her panties as she passed by her older brother in the hallway. After shutting the door to the bathroom she couldn’t help but think about how muscular her brother’s body looked when he wore nothing except his sleeping shorts. The bulge he always had on display looked so delicious and so ready to pound any female in its proximity, it felt intoxicating. Emily felt ashamed of these perverted thoughts, but couldn’t deny how attractive her older brother was. He was 4 years older than her and they didn’t have much in common so they rarely spent time together. But Emily made sure to check out what her brother did with every occasion. She especially liked peeking when he was working out in the backyard. She had more than a few orgasms just by watching her brother do bicep curls or bench presses. The way his body got pumped up got her wet every time. She always ended up sneaking 2 fingers in her pussy and watching him for hours, moaning silently as she masturbated to her brother’s masculine physique. She wanted a body like his, but could never achieve it, no matter how hard she tried. Deep down, she felt like her brother stole all the good genes at birth. He was 6’2’’, had broad shoulders and big muscles, as well as a handsome face to go with it. And even though she was by no means ugly, she was stuck being skinny and short, while he was a teenage Adonis. It always felt unfair to her.

As she undressed and got into the shower she couldn’t help but think about the time she saw him masturbating after a brutal workout. Before that incident she had seen him naked a number of times, but never sporting such a monstrous erection. That thing was very big. She saw him jerking off as he was sitting on the edge of his bed, probably watching some Instagram thot’s profile or some of the teasing videos his girlfriend kept sending him. His penis was ludicrously hard and veiny. It was quite a treat for her to see such a hunk jerk his hard meat like that. Looking at her own cock, she realized that cock size was another thing he outmatched her at. Not only that, but he masturbated for hours as his body required a lot of stimulation to release all tension, as well as the massive load pent up in his balls. As she turned on the water, she still couldn’t get the image of her brother stroking his dick out of her head. The tingling sensation came back as the hot water started pouring and steam filled the shower. Her dick began to get hard again. This time, she got way more excited about it. Then she noticed that the tingling was also present in her nipples. They were growing harder under her eyes. She stared at them with genuine fascination, but also noticed that her body was a little bit bulkier than before. She had a little bit more meat on her body. But maybe it was just her imagination.

With her heart beating fast, she reached down and started to stroke her penis. It felt larger than before. It was probably about an inch or so longer. This thought excited her even more. The thought that it was bigger was an unexpected thrill to her and introduced the thought that it might keep growing if she kept playing with it. If she was sad about it before, now she was fully embracing her growing dick. Her cock was painfully hard now. All those lewd thoughts made for great stimulation and got her beautiful girl-cock as hard as a steel pipe. After only a few dozen strokes she let out an orgasmic “OOOHHH!!” and a sizeable cumshot came out with such force it let out a powerful thud as it hit the shower wall. This orgasm was much more intense than earlier and it produced way more cum. Her legs felt weak as she leaned on the side of the shower. Her body trembled as the tingling spread through her being, causing her to groan. After a few moments she gathered herself and finished her shower.

As she got out of the shower she caught a glimpse of herself in the mirror. It seemed her boobs have grown too. “No fucking way!” Emily thought as she grinned. She fondled them a little and ran her hands all over her hard nipples. “I can’t believe I finally have boobs!! God I love them!” she giggled. She then looked at her cock, which seemed to have grown again too. Completely flaccid it looks just as big as it did a little while ago when it was fully erect. She looked back again at her beautiful breasts with the thought that maybe she’s only just now started puberty. She didn’t know what was going on, but she sure as hell liked the changes, be it puberty or something else. With a much better mood and her libido in check for the time being, she got dressed as she daydreamed of more changes like this to come. Everything piece of clothing she tried on was pretty tight, so she had to go with the largest clothes she had. “Jeez, even my shoes feel tight! I have definitely grown all over!” She looked at herself in the mirror, ogling the wonderful changes to her body. She had more curves, a slightly visible abdomen and a more womanly body overall. She put on a T-shirt and finished up preparing for school.

Today her brother had to drive her to school as her mom was busy getting ready for a business meeting. Emily was lost in increasingly hopeful thoughts about her body during the car ride. She didn’t have any bras as she didn’t need them before, but now her larger nipples were poking shamelessly through her shirt and Lucas couldn’t help but take small glances at them. He was feeling slightly uncomfortable peeking like that at his sister’s tits, but he just couldn’t help it. Emily however didn’t notice, being completely lost in the thought of how wonderful it’s going to be to finally look like a proper girl. “Goodbye, Lucas!” Emily waved lovingly before she started walking towards her class. The way she moved was different too. Now she was shifting her butt left and right as she walked and her thighs were not far from touching each other. “Bye…” Lucas replied hesitantly noticing his sister’s ass for the first time ever. The tight pants certainly emphasized her now noticeable curves. During school time Emily fell into her normal routine, completely forgetting about what happened in the morning for the time being. She was a good student and even though school wasn’t easy for her, she worked hard to get good grades. She noticed some colleagues ogling her during class, but didn’t pay them too much attention.

Things went pretty much normal until PE class. Changing into her running tights she was quickly reminded of her new addition. There was no way ignore the bulge in her panties. She scanned the room nervously to see if anyone noticed it, but all she could see was a room full of breasts larger than hers on beautiful girls who were all taller than she was. Nobody really cared about her so they didn’t bother looking at her. Although her body had improved greatly, she still had some work to do until she reached the other girls’ level. The workouts themselves proved to be very easy, something which was not common for her. During the last half of the class, she had to do a long run. As she ran, her new, thought still not very large, still unsupported breasts were jiggling in her shirt, rubbing her large nipples against the fabric. She was getting more aroused every time they bounced. Her penis began to enlarge. The small bulge wasn’t too noticeable at first, but the constant grinding against the sensitive foreskin and especially sensitive head was driving her nuts now. Emily decided to speed things up, not just because it was too easy at the current speed, but also hoping to finish sooner so she could do something about her problem. This proved to be a bad decision as the shaking in her groin increased and the constant rubbing became even harder to ignore.

She took the lead, tearing through the rest of the run in record time. Out of breath, she asked to use the restroom while the others were still going. By the looks of it she had about 5 to10 minutes before they were all done. Emily rushed to the nearest restroom, her balls aching like they were on fire as she ran. She got into the first stall and removed her sweaty clothes. “OMG!! OMG!! I’m so fucking hard! It hurts so badly!! I need to do something!!” she said quietly as she stared at her pulsing cock. Her cock and balls looked to be slightly bigger that those of a boy her age. However, most boys her age were at least one foot taller than her, so her penis looked huge for her current size. Her erect penis was 5.5 inches long and a thick vein ran confidently on top of it, shaking violently, almost begging her to release her load. She wrapped her hands around her shaft and squeezed it hard, feeling the burning fire inside it. Emily began to jack off right there and then, not caring if there was anyone in the other stalls. Her body began to tighten all over, feeling immense pleasure emanating from her hard cock. Her muscles were growing. Thick veins became visible on her forearms as she stroked her cock harder. She could also see her abs and obliques becoming beefier and more visible than ever. Not long after did she start to feel a powerful orgasm building up and becoming harder and harder to contain. Her cock started leaking pre all over the floor and it also seemed to become larger the harder she jerked it.

All of her muscles were twitching and the warm tingling spread deeper into her body as it became warmer and more intense than ever. Sweat was running down her neck and onto her increasingly larger chest as she continued to masturbate. Her moans were loud and the pre created a small mess at her feet. Her entire body was on fire as she was nearing another powerful orgasm. “OH FUCK!!” she gasped as she came, splashing the door of the stall with 3 ropes of dense cum. The next few shots were smaller, but they did their job, her cock finally starting to soften back up. The bell rang a few moments later, snapping her out of her orgasmic bliss. She ran back to the locker room, instantly forgetting about the mess she just created in the stall. She noticed that putting on her clothes was now giving her lot of trouble, even more than before. Her jeans barely fit her butt now. She painfully stuffed her large dick into them before zipping them up with great effort. Her ass was definitely bigger and her legs way meatier, with nicely shaped curves separating different muscle groups. She ignored her discomfort and finished getting dressed. Her boobs were bigger too, making her shirt rise higher than before and putting her abdomen on full display. She was had a pretty visible 6-pack now. Her arms were tighter too, showing some decent muscle mass all over. The T-shirt felt tight all over, including her back and shoulders. Naturally, she received some lewd stares on the way to the next class. Her braless breasts drew even more attention to her large nipples now. Her big ass and nicely shaped abs turned some heads as well, some boys wondering who this new girl was before realizing it was actually Emily. Thankfully this next class was her last for the day.

Outside, Lucas was waiting in the car for his sister to get out. He hoped that her nipples would go back to normal, but that didn’t seem to be the case when he saw the new Emily walking towards the car. Her tits were even bigger and her nipples pointier. Not only that, her fully exposed belly caused him to sweat profusely, as did her hot legs and wide hips. She was slowly but surely turning into a bombshell. “Can we hurry home please?” she asked as she got into the car. John desperately tried not to look at her on the way back. It proved extremely difficult each time her boobs jiggled, pushing her shirt closer and closer to its breaking point. Lucas had a visible hard-on the entire time. His cock was hurting and Emily noticed it. She didn’t know what to say so she just kept silent. She was also wondering if she her cock was bigger now. Lucas may still have a slight advantage, but that may not last very long.

Emily ran to her room as soon as she got home, leaving a deeply aroused Lucas alone to call his girlfriend. In her room, Emily threw her clothes away, excited to finally get a good look at herself, but mostly to relieve the painful pressure pants were applying to her balls. “Holy shit!! I guess puberty did come late, but it fucking came all in!” Emily couldn’t believe her eyes. The first things that drew her attention were her nipples, which were double the size they were this morning. But her attention was quickly redirected to her now fully formed breasts. She was ecstatic to finally have breasts. And they weren’t small at all. She still didn’t understand what was going on, but also couldn’t care less at this point. Her big boobs were spectacular, round and very nice to the touch. And they weren’t the only thing developing at a high rate. Her body was bulkier and not just in a voluptuous way. She was definitely more muscular than ever before. She had always been so weak, even scrawny for her size, but no more. She brought her arms up for a bicep pose and was rewarded with decently sized biceps peaks. They weren’t nearly as big as her brother’s, but were definitely an improvement. As she inspected the rest of her body, just after squeezing her round ass, she began to get aroused. Her tummy was now a board of hard abs, all of them nicely toned and mesmerizing to look at. Her legs were thick and muscular, looking like they belonged on a certified athlete and definitely not on someone like her. But this was the new Emily. And the new Emily was a far cry from the old one.

“I can’t believe how fast I’ve grown. I don’t know what’s happening, but I don’t want it to stop!” she smiled, getting turned on by the thought of her body developing further. This brought her attention to something else that has apparently developed way more than she anticipated: her cock was now 8 inches long and twice as thick as before. She had big fat veins running all over its impressive length. “I wonder if I’m the big sister now.” she said with a lewd grin as she grabbed her cock and gave it a few strokes. She then checked out her balls, each of them as big as a ping pong ball.

She started stroking it yet again, only this time something was different. All of her muscles seemed to be getting stimulated by her movements. Her nipples ached and pulsed and her pussy was just as hungry for stimulation as her fat cock. She opened a drawer and pulled out a 6 inch dildo then immediately shoved in inside her wet womanhood. “Oh fuck yes!!” she moaned as she continued to stroke her throbbing cock. Her pussy was also way more sensitive than ever before. “Oh fuck!! I need more!” she said as she picked up the remote and shoved it inside her pussy without a second thought. Her muscles were growing before her eyes as she was quickly approaching ejaculation. Her eyes bulged and her mouth opened wide as then she arched her back while standing on her toes as her cock shot a huge load of jizz across the room. Her whole body throbbed for a bit and she collapsed onto her bed with a soft groan. For half hour of she just laid on her bed, her entire body sore as if she completed a full body workout. She eventually stood up, only to be startled by the substantial globes of flesh hanging from her chest. ”Fuck me!! Look at those!” Emily said as she grabbed the two large, firm and incredibly round breasts sticking straight out of her muscular chest. Both of them ended with a very big and juicy nipple that stood as hard as a small cock. Her muscles also developed further, now looking twice as big as before. She flexed them again and again, basking in the glory of her sculpted physique. She looked hard all over, with beautiful muscles bulging and flexing with every movement.

“Wait, am I taller too?” she said with visible excitement as she measured herself. She was 5’2’’ feet tall. “OMG YES!!” she giggled like a little girl. Looking down into the mirror she finally saw the big fat cock and fist-sized pair of balls hanging between her muscular legs. She loved her girl-cock so much now. She couldn’t help measuring it. It was 10 inches long and even thicker than before. This was no ordinary cock, this was a monster dong that belonged on a freakin’ horse. “I’m definitely the big sister now!” she said as she marveled at the giant piece of meat hanging between her legs. She then remembered that she still had the remote and the dildo stuck inside her pussy. She spread her legs and effortlessly pushed them out at the same time, making them crash against the cum-stained floor. They were too small for her new body. She needed something bigger. She also weighted herself. She was now 210 lbs, more than twice her former weight. But this was all muscle mass and tit-meat. “God I love this body! I wonder how much more I can make it grow.” she said as she flexed again and again, exploring every little part of her wonderful physique. She was now as big as an average bodybuilder, had tits as big as her head and a cock that would put 90% of the male population to shame. Puberty hit hard and it hit right in her sweet spot. The more she looked at her body, the more she wanted to use it. And she knew just how to use it to its full extent. After sporting such a hard-on for such a long time, it was clear to her that Lucas would pick up his girlfriend and bring her back home to fuck her brains out like he always did. She was determined to make it a threesome.
