Chapter 1: The skinny girl who wished to be buff


**This story contains: huge muscles, muscle growth, huge cocks, cock growth, anal, excessive cum, hardcore sex, squirting, drugs, steroids and probably some other great stuff.


Madison was a small girl from a small town in Atlanta. She was about 5’ 3’’ (about 160 centimetres) and 112 lbs (approx. 50 kg), with brown eyes and a long brown hair that reached just a little below her shoulders. It’s safe to say that she was a beautiful girl, her eyes were bright and big, her nose was just the right size to fit between them and her cheeks looked so full of life. But, by far her most redeeming facial features were her lips. They were incredible, so meaty, so strong and so soft at the same time. There was also the fact that she could fit a great deal of cocks between them, but we’ll get to that. She also had amazing teeth, white and pretty to look at, but not the bright and in-your-face type many celebrities have nowadays. Her ears were small, as well as her head. Although she had a pretty face, her body wasn’t really anything to write home about. She was pretty skinny, with hardly any muscle on her frame. Her boobs were very small, her ass was a little bit better, but not by much. As you can imagine, as a girl living in 2019, she was not happy with how she looked. She used to look at most of her female high school colleagues and envy them with all of her heart. She hated how the girls had boobs which belonged on 25 year-olds, asses which belonged on porn stars and athletic frames with just the right amount of bodyfat. Yes, she was pretty, but so we’re many other girls and they also got de physique to match, so it was obvious who the boys would choose when it came to sex. And, oh boy, was she a horny one! She would masturbate every night, from 10 pm to 2 am, mostly to hardcore straight sex, but also BDSM, squirting, large toys insertions and fucking machines. But the one thing she had always desired besides sex was MUSCLE MASS.


She had countless wet dreams in which she was brutally fucked by muscular men. At first they were fitness models, muscular, athletic, charming but not very big. After some time her imagination went further and she was fucked by the likes of Arnold, Flex Wheeler and Phil Heath. She would pump them full of growth hormone, testosterone and drugs with large syringes and would have sex with them for hours, days, even weeks. Her dreams were just wild: she was riding them for hours, her pussy bouncing up and down on their 10 inch dicks ( that’s what she imagined their cocks were like), while she ran her hands and tongue on their huge pecs, chiseled abs, and then French-kissing them like a madwoman. She would caress their strong biceps, feeling every pencil-sized vein, every striation and every inch of muscle and masculinity. Then, one by one , they would fuck her doggystyle, ramming their enormous rods in her tight pussy, sometimes all at once, blasting her with huge loads of semen. Her ass would be next. Using an entire bottle of lube per fuck session, the bodybuilders would punish her poor little asshole like there was no tomorrow. Without ever giving her poor asshole a break, they would take turns stretching it to the absolute limit. And she was so happy when she felt her tiny asshole stretch like crazy! She loved every minute of it. Often her eyes would roll back inside her head with both pain and pleasure, but she would stay conscious to take it all. Then it was time for missionary. One by one, the musclemen would insert all of their manhood in Maddy’s pussy, their huge veiny balls striking her gaping asshole with all of their might as they went in and out of her. Then they would cum. Loads and loads of thick cum, without caring if it was in her pussy, on her stomach, tits or face. And she would drink as much as she could, until she was full and about to pass out. She would fall asleep on the three muscle men, resting her small body on their monstrous physiques, her lips glued to one of their humongous cocks even in her sleep.


And then she would wake up. The entire bed was wet with her juices, as well as lots of water (she liked to stay hydrated, but also squirted a lot). Her numerous dildos, some the size of baseball bats, were scattered around the room. Her pussy and asshole were pulsing, but she was satisfied. She didn’t really bother cleaning the mess up, since the next night would be just the same. She didn’t really bother with housework, since she lived alone in a decent sized apartment on the suburbs. Since her apartment was located in the basement of the block, her neighbors would not hear her scream as she orgasmed, or the wild porn she was watching every day. Maddy would just open the 2 small windows of her home,(that reached the back of the block, where people would rarely go to) letting the entire mess she made dry up. Although physically speaking, she was below average, in the brains department she was a little genius. She graduated in the top 3 of her class at one of the best high schools in the region, then went on to study bio-engineering and biology at one of the most prestigious universities in the country. It was there that she discovered her love of muscles and huge dicks. Since she was skinny, she would mostly date nerds who played videogames in all of their spare time or teaching assistants of other faculties (she didn’t want anyone to think she was sleeping around to get good grades, she was doing it just for pure pleasure). She would usually fuck the boys on the first date, since she couldn’t really contain herself when she was horny. Although they were mostly out of shape and their dicks weren’t too big, she was satisfied most of the time. She had a few relationships that lasted a few months each, but nothing too meaningful. That was until she met Jack.


Jack was a student at the same university, but he specialized in Health and fitness, personal training and nutrition. He was also an amateur bodybuilder. They met at a rock concert by accident, drank a few beers together (although she drank more, since he was preparing for a competition at the time) and decided to go to his home. Of course, she fucked him like a wild animal, and he returned the favor. They fell in love and stayed together until they both graduated. She would go with him to every competition, often giving him a blowjob before and after the show to keep his confidence up. That seemed to work very well as Jack would be in the top 5 on every competition and also go on to win 2 of them. He also tried many times to train her, coach her and prepare nutritious meals so that she would become more muscular, but with very little results. After the graduation, Jack suffered a terrible injury that left him unable to train or do too much physical activity for at least a year. As you can imagine, he was devastated. He had to move back with his parents in his home town (which wasn’t very far, it was a 5 hour drive) and the two had no choice but to split up since he didn’t want her to “have to look after a cripple”. Also, knowing her insane sex drive, he would be in no way able to satisfy her.


She started working at a lab that partnered with HYPERMUSCLE-X, a global supplement company that was constantly improving its products to appease their clients (and also make massive profit in the process), but they only kept the best stuff for their own models and management. She would use her sharp mind and vast knowledge to test new ways formulas, serums and pills that increased muscle performance and size. Her discoveries were incredible: she was able to speed up the muscle growth of normal humans up to 5 times the normal amount. Some of her serums would also clean the blood of any toxic substances and increase the production of sperm of all subject by at least 3 times. In other words, she was making muscled studs out of ordinary couch potatoes. It’s safe to say she loved her job. After she left home, she would often call her “subjects” to come over and “thank her” for the results. They always came to her home near midnight, fucked her brains out for 3-4 hours straight and let her covered in cum and pussy juices. Of course she loved being fucked like a whore by young studs. What she didn’t like is the way they talked about her. “Skinny bitch”, “flat chested”, “small bird”, “big brained cunt”, she heard them all, and hated them all. One day, she decided it was time to change that. She wanted MUSCLE, TITS and ASS. And she was more motivated that ever to get them all. Little by little, she started to take more and more of her work tools home to work on what she called PROJECT MADISON. She took home samples of all the serums she produced for male and female subjects. Then she went on the dark web and procured the strongest steroids possible, along with  2 crates of testosterone and other growth hormones. Then went on to find the best saline implants on the web and ordered 6 of the biggest ones. She had plenty of money since her job payed well and she didn’t do much besides work. After she got all the tools and materials needed, it was time to start working on the best project of her life: herself.


Maddy worked on the new formula for about six weeks. When it was ready, she named it MGE-1 (short for Madison growth elixir v1). Now she had to test it, so she drugged a beggar that would usually sleep in the alley behind her block and brought him inside. The drug was so strong he would be asleep for at least a day. She had to wash him, shave him all over his body to inspect the progress and inject him with some vitamins, before tying him up to her spare bed. She injected him with the formula and waited for about 15 minutes. During this time, the man’s body kept pulsating and kept increasing in size. At first, the growth was slow, then it picked up the pace. When the timer hit the 15 minute mark, the beggar she dragged home was completely gone. She had in front of her a world class heavyweight bodybuilder, with pecs 3 times the size of her head, arms almost 2 times her waist, tree trunks for legs and a humongous 11 inch dick (soft) as thick as a soda can that came with a pair of tennis ball size balls. The man’s wrinkles, cuts and bruises had all disappeared, his skin was soft, his muscle hard as steel, and his body was plastered with pulsating pencil sized veins. He looked incredible. Maddy has never been so horny in her life.


She got naked in an instant and as she was standing next to him, she started touching her wet pussy. In less than 5 seconds, she came. And she came hard. The insane orgasm made her squirt like crazy all over the colossus before her. He was now soaked in her juices. Her knees were shaking, her pussy throbbing like crazy as she just had the most intense orgasm of her life. She couldn’t wait anymore. With the quickness of a cheetah, she grabbed de monster cock with both hands, stroking it like her life depended on it, licking and sucking the tip at the same time. She bit the tip of his cock, put her entire tongue in his cock slit, caressed his huge balls. She was in heaven. She felt the monster come to life in her hands. The dick got hard as steel in no time. It was just marvelous. Over 14 inches of hard meat, ready to fuck her small body to kingdom come. The precum started flowing like crazy, not stopping for a second, engulfing the phallus in it’s abundance. And it was delicious. She drank as much as she could while sucking the tip with her goddess lips. The veins on the cock were throbbing continuously, and the great vein looked ready to burst at any moment. The ones on the balls looked like little wires connecting the great rod to the sperm factories below. An there was a lot of sperm. Those tennis sized testicles became bigger and bigger the more she stimulated them. The contents were ready to be released. As Maddy felt the monster ready to erupt, she put her entire head around the tip, trying to deepthroat the whole thing. Of course, she wasn’t able to, but she did her best to take as much as possible. After a few more moments, the monster erupted.


The giant's whole body started shaking as rope after rope of delicious and nutritious cum burst out of his mighty cock. Madison felt the force of every cumshot in her mouth, and there were about 12 of them. 12 shots of thick cum hitting her skull with the force of a freight-train. She felt dizzy after the last few cumshots. And full, as she swallowed every shot. But, most importantly, she loved the feeling. She came alongside the massive cock with tremendous intensity, her pussy now throbbing even crazier than before. She had to take a few moments to recover from all the punishment her head took. She unlocked her mouth from the tip of the cock and took in a few breaths of fresh air. Also, she noticed that he was starting to wake up. That was not good. She couldn’t know how a man from the streets would react to this type of situation: being drugged, kidnapped and experimented on, and eventually turned into a muscle monster. She had to think fast, as he was almost out of his deep sleep.

Chapter 2: The new assistant


**This story contains: huge muscles, muscle growth, huge cocks, cock growth, anal, excessive cum, hardcore sex, squirting, drugs, steroids and probably some other great stuff.


Maddy knew she couldn’t inject the monster with another dose of tranquilizer, so she had to make him obey her. She grabbed the pheromone spray she invented a while back and sprayed herself with it 5 times. The pheromone spray was invented so that she could be irresistible to men, mainly to convince them to fuck her if they weren’t willing. Of course, she only used one dose and it was enough to convince other to do what she wanted. Using this much, she was just irresistible. The muscle monster woke up and was really lost. He had no idea what happened or where he was.


“ Where am I? What happened ? Wait, is this me, how did I get so buff? Damn I feel as big as Ronnie Coleman in his prime.” He flexed his massive right bicep a few times. It has humongous, made of pure muscle, covered in veins, pulsating with power. He enjoyed this feeling of raw power.

“I made you like this.” said Madison, slowly approaching the giant.

“Who are you?” said the man.

“Your mistress.” as she said that, she leaned over and grabbed his massive arm, feeling every muscle on display. “You were a junkie, a beggar. I made you into the most incredible stud in the world. You will obey me from now on.” Madison took her time, came very close to him to make him breathe the pheromones.

The man looked a little confused, but he nodded in approval. “Yes, mistress”.

“Now, tell me your name.” she said.

“My name is Kevin.” The giant answered.

“Well, dear Kevin, you are now my assistant. You will work with me, live with me, have sex with me and do anything I ask of you.”

“Of course, mistress. Anything for you.” he said without any confusion left.

“Now, stand up so I can take better look at you.”


He stood up. He was about 6 foot 9 (205 cm) tall, without a single hair on his entire massive body. Saying he was jacked would be an understatement. He was huge, muscles everywhere, the symmetry of his body was perfect. His now flaccid cock hanging between his massive legs, his sperm factories moving slightly from the high production rate of the semen. She inspected every inch of his body closely. She liked it. A lot.

“Turn around.” she said.

He did so. Maddy had never seen such a perfect ass on a man in her entire life. It was all muscle, but it was also round, beautiful, and mouth watering for any young girl. She slapped him a few times, just for good measure. She was sure he didn’t really feel any pain, maybe just a slight arousal. She went back in front of him and took a seat on the bed.

“Flex those sexy muscles for me. I want to see everything.” the girl said.


He started with a simple bicep flex. Then went on to do a double bicep flex. He looked like a greek god on steroids since the day he was born. He would make Phil Heath in Mr. Olympia condition look not that impressive by comparison. He hit a most muscular, displaying the young hard beef he was packing on his upper body. Then he flexed every muscle on his legs, one by one, ass, quads, calves, they all looked perfect. Then he flexed his incredible abs, each of them as hard as concrete and as big as bricks. You could definitely crush stones or bent steel between them. Madison was het again down there, but she wanted to see everything. From the excitement of his own intense flexing, his massive cock became hard. He was aroused as hell by his new body. But he was only a slave to Maddy. When Maddy saw the giant rod rise in front of her, she came instantly from anticipation, then fell back on the bed. Kevin stood there, trying to relax his massive physique.


“You are incredible. This is the best discovery ever.” said Maddy, as she got up and went to the lab table where she mixed the serum. “Now I need to make sure this will work on me too and also see how well you are on the inside.”

Maddy spent the next hour doing a variety of tests on Kevin, all of which took some time to produce the results. She wasn’t sure how long the pheromones would work, but it was probably more that a few days since she used so much. She decided to use the time productively and asked Kevin to fuck her into oblivion. He, of course, was happy to comply.


“I want you to fuck me, you freak. Fuck me like your life depends on it, because it surely does. Don’t hold back, you hear me? Fuck me in my pussy, my ass, my mouth, and cum everywhere as much as you can. When I see those huge pecs and those incredible arms I feel so turned on, damn! And that giant dick of yours makes me so wet I might die of dehydration. I want you to impale me on that huge fuckstick! FUCK I’M SO HORNY RIGHT NOW, GET ON THE BED!”

Kevin leaned on his back, his massive frame almost covering the whole surface of the bed. His dick was rock hard and he was ready to please his mistress. She began to suck his cock with her strong lips, all while caressing his massive balls with her nails. Kevin has never felt so much pleasure in his life, but he also remembered what she said: “Don’t hold back!”. He grabbed her head and pushed his massive phallus inside her throat. He pushed more and more until half of his cock was inside her throat. Then he pulled out, leaving her a few seconds to breathe. He did this 10 more times, punishing her throat without mercy. Maddy had tears of pleasure on her face, but also tears if pain. Of course, she loved both feelings equally. Maddy continued to lick his massive balls, one by one. Then she bit them with some force, enough to make Kevin shiver with excitement.


She got up after that and went on to ride him. Of course it was difficult since he was so big, but she wasn’t one to quit. She barely inserted the tip of the cock in and she orgasmed instantly. Kevin felt her tight pussy trying to go over his cock head. She struggled to squat on the giant rod, but could barely fit any of it inside her except the tip. Kevin grabbed her hips with his strong hands and brought her down with a powerful move. She orgasmed 3 times on the way down, her eyes were crying, her pussy was squirting like a fountain and she was screaming like she was actually impaled by a roman spear. The squirt travelled right onto Kevin’s face and he opened his mouth to catch it all. He wanted everything his mistress offered him, especially if it came from her pussy. He moved her up, revealing his soaked cock dripping pre and Maddy’s pussy juices. On the way up, she orgasmed again. Then he pushed her down again. And up again. He moved her just like that again and again , the poor girl continuing to cum again and again for another half hour, enjoying every second of it like the crazy whore she was. Maddy had countless orgasms during this time and lost herself in the mix of pleasure and pain. Kevin noticed after a while that she had passed out and stopped. He placed her gently on the bed and noticed her pulsating pussy, dripping loads of his pre.


After about half a minute, she came about.

“What the hell?! Why did you stop? “ she said.

“I thought you were out so I … “

“I SAID NO MERCY! What part of it did you not understand?” said Maddy, visibly irritated by the actions of her muscular slave.

“I’m sorry, mistress. It won’t happen again.” said Kevin with a sad face.

“It better not! Now fuck me!” she said, turning her ass around and spreading her asscheeks wide to invite de colossus inside of her. She wanted to be fucked doggystyle now.


He got hard in an instant and began pounding her without mercy. He inserted his rod inside her pussy, then inside her ass, then again in her pussy and again in her ass. He was using his whole body trying to fit more than half of his manhood inside Maddy's holes. His massive legs even cracked the floor beneath them. Maddy cried and orgasmed non-stop for another hour, while Kevin pounded her in a perfect rhythm of normal and anal destruction. All of this time, she kept saying “HARDER!! MORE!! FUCK ME HARDER YOU MUSCLE FREAK!! YOU ARE MY SLAVE, YOU ARE MY JACKED STUD!! FUUUUUUUUUUCK!!!” Kevin was sweating a lot , and also leaking pre like a broken faucet. She loved the smell of Kevin’s manly sweat, it turned her on even more than she already was. It was probably the effect of her serum that made the smell so enjoyable. When Maddy was about to pass out again, Kevin came hard. He came with the force of a fire hose, blasting her pussy, ass and back with loads and loads of thick semen. Maddy tried her best to keep as much of Kevin’s cum inside her as she could, as she loved the feeling of being bloated with semen. And this stud's cum was thousands of times thicker and more delicious than that of a normal man. After such a display of power, stamina and virility, Kevin was finally tired.


“You did very good, Kevin. I am pleased. Let’s go to bed, stud. We have a lot of work to do tomorrow. Your mistress needs a body like yours… or maybe even BETTER!”

She took his hand and they both went to bed. Not the bed they just destroyed with the most hardcore sex any of them ever experienced, they went to the king-sized bed in the other room. Maddy and Kevin kissed each other passionately for 5 more minutes. She noticed how beautiful his blue eyes were, now that they're faces were so close. She fell asleep with her head rested on his massive chest, hands on his imposing set of abs and his massive flaccid cock right between her feet. She slept like a baby, her holes pulsating slowly the entire night, trying to somehow repair themselves after being wrecked by the massive cock of Kevin. She had the best dream of her life that night: she dreamed of how HUGE she was about to become.

Chapter 3: The first dose


**This story contains: huge muscles, muscle growth, huge cocks, cock growth, anal, excessive cum, hardcore sex, squirting, drugs, steroids and probably some other great stuff.


Maddy woke up at about 10 am the next morning. To her surprise, she was alone on the bed, her new assistant was nowhere to be seen. “Did the pheromones wear off?” she thought. “No, it can’t be. I’ve used too much for it to wear off so quickly.” At this point she was starting to get worried about what could happen next. Less than half a minute later, Kevin entered the room with a tray in his hand. He was naked, of course, and seemed very well rested. She couldn’t get enough of the view: those powerful legs slightly touching one another from the sheer size as he walked, those huge ripped arms, that incredibly wide chest with its bouncing pecs,  his enormous cock dangling in front of him.

“I brought you breakfast, mistress. Hope you’ll like it. If not, I can make something else.” said Kevin, leaning forward to put the tray in front her.

“Wow! I did not expect that, stud. Damn, a hunk AND a gentleman. Thank you!” said Maddy, visibly excited.

Although he was no master chef, he did his best to provide a good first meal of the day that brought a smile on Maddy’s face. After she finished breakfast, her first thought was to reward Kevin for the nice surprise. But then she remembered: the test results should be ready by now. As much as she wanted to fuck her muscled monster right there and then, she decided to focus on the job, at least this time. She went to the lab and checked the results: Kevin was as healthy as he could ever be. Not only that, but his measurements were off the charts: his testosterone was through the roof, his blood was as clean as sparkling water and he was about 5% bodyfat. Of course, if you looked at him, you would think he was made of pure muscle all around, which wasn’t really far from the truth. The serum didn’t seem to create any side effect, as far as she could tell. To say that she was pleased with herself would be an understatement: she was delighted. She couldn’t contain her excitement as she was minutes away from realizing her dream. She grabbed the largest syringe she had in the lab and filled it with MGE-1. She called for Kevin, as she wanted him to witness her transformation, and assist her if something were to go wrong. She was ready.


With a single powerful move, she injected the syringe into her arm and emptied it’s contents in seconds. Nothing happened for about a minute. Then it started. Her blood felt like it was boiling, her bones felt like they were all being cracked at the same time and her heart rate doubled. It was painful, but she wouldn’t have it any other way. Her muscles started to swell harder and harder with every passing second. Her back was getting wider as her torso turned into a V shape, getting stronger, packing heavy slabs of muscle. Her chest was now packing two large plates of pure beef, along with some incredible new large tits. To give you an idea, her new tits were twice the size of Lisa Ann before retiring from porn, round and delicious, with hard nipples begging to be played with. Her legs were getting bigger and stronger every second, quickly surpassing most female bodybuilders. Her ass was increasing in mass as well, becoming rounder than any brazilian woman could ever dream, but made of dense muscle and very little fat. As the transformation occurred, all Maddy could do was scream like a possessed woman: “MORE!! YES!!! MAKE ME HUGE!! MORE MUSCLE!! MORE!!”. Her arms swelled as well, pulsating with power, her biceps now looking like little balloons, her triceps doing they’re best to keep up, her forearms riddled with matching size and pulsating veins all over. Her shoulders looked round and hard as armor padding, providing her with the best muscle symmetry a woman could ever hope to achieve. Her six pack abdomen was phenomenal, little bricks packed into one another, fighting for space on her gorgeous torso, turning her insane V shape into a thing of artistic beauty. The skinny girl from yesterday was now bigger than Gracyanne Barbosa, with arms larger that Kristen Nun and an incredible pair of large tits that would put all pornstars to shame. She was also shredded, covered in wire-like veins all over her muscular body, her arms especially packing tremendous vascularity. Her face also became prettier, all he tiny imperfections were now gone. Her skin became softer and slightly darker, like it was tanned in natural light  (she was pretty pale before), her hair grew a little longer and much stronger than before. The closer she was to the end of the transformation, the less pain she felt, all the pain turning into pleasure. After about 5 minutes, a lot quicker than Kevin, the growth stopped. At this point, Maddy was flexing every muscle in her body, wanting to increase the intense pleasure she felt while she grew. She orgasmed at least 10 times during the whole transformation and was now covered in sweat, tears and pussy juice. She has never been so happy in her entire life. She ordered Kevin to bring her a mirror so that she could see herself in all of her glory. He complied, of course. Maddy looked in the mirror and her confidence went through the roof. She was jacked, with big beautiful muscles everywhere she looked,  a pair of tits bigger that her head and probably the best ass in the whole wide world. She also got taller, now standing 6 foot 3 inches tall. She flexed in the mirror for a few more minutes, making sure she didn’t miss a single muscle on her incredible physique. She squirted one more time from sheer excitement, the powerful shot flying right into the mirror and covering it whole.


“Damn, stud. Look at me! I look bigger than the She-Hulk, only prettier and a lot bustier!! YES!! Look at these muscles, they are so big and strong and they feel so good when I flex. And these big fucking tits are so big, so sensitive! I thing we need to test them out, don’t you think?” said Maddy with a perverted smile.

“Of course, mistress. Anything you wish.” said Kevin, already rock hard from the display he just witnessed.

“Bring that hard cock over here! This time, I want it ALL inside me.”


Kevin’s started stroking his huge cock with one hand while Maddy got on her knees with anticipation. She opened her mouth wide and took one of his enormous balls in her mouth and started using her lips and tongue to pleasure the giant’s testicle. She licked every vein she could find, then took the other ball in and applied the same treatment. Kevin was feeling great pleasure as she continued to stroke his dick, slowly increasing the speed. Precum started flowing like crazy on Maddy’s muscular back, then dripped on her perfect ass. She then proceeded to take the giant penis inside her mouth. She took a deep breath, relaxed her neck muscles and pushed her head forward against the massive shlong. She took about half of it in without too much effort. Kevin grabbed her head and pushed his monster deeper inside her throat. She managed to squeeze inside her throat about 2 thirds of Kevin’s giant dick. He fucked her throat just like that for the next 15 minutes, barely giving her a few seconds to breathe once in a while. The choking sounds only made him harder, so he kept increasing the force behind his thrusting, his muscular forearms now riddled with enormous pulsating veins. Maddy loved how she was now able to take much more of the monster inside her throat and loved the feeling of being facefucked by her jacked assistant. She flexed her neck muscles constantly to tighten the grip she had on his cock and make him feel even better. Meanwhile, she used her one of her strong hands to play with his balls, while also masturbating with the other. Kevin came hard inside her throat and the girl took all of the dense sperm directly inside her stomach, not wasting a single drop. He must have cum at least 1 litre in total (0.27 gallons). She now was a little bloated, the cum inside pushing against her perfect abs.


“Damn, so much cum! I hope you have more inside these balls because we are just getting started.”

“Of course, mistress. I’ve got plenty more where that came from.” said Kevin with a proud smile.

“But first, I want you to play with these huge boobs” she said as she grabbed her perfect orbs with both hands and squeezed them hard.


She laid on her back on the bed and waited for him to make a move. Kevin came closed and started to squeeze the huge boobs of Maddy, while also using his tongue to pleasure her rock hard nipples. He smacked her boobs with his strong hands, bit her nipples, licked them in every way he could think of,  doing whatever he considered necessary to make his mistress feel good. And she wasn’t just feeling good, she was feeling fantastic. She was in a continuous state of pure bliss. She came a few times during this time and moaned non stop. Occasionally she would say: “YES, STUD!! YOU ARE SO GOOD!! FUCK!! DON’T STOP!!! YOU MAKE MY BOOBS FEEL SOOO GOOD!!”. He managed to get her even hornier than before. She came again, this time more powerful than ever before. Much to her surprise, her nipples sprayed milk everywhere like two powerful geysers. Kevin quickly realized that and used his mouth to catch as much milk as he could. It was delicious, sweet and so much of it you could fill at least 3 cartons of milk.

“My boobs are spraying milk everywhere! DAMMIT, I LOVE THIS FUCKING BODY!! YES, DRINK IT ALL, YOU STUD! DRINK YOUR MISTRESS’ MILK LIKE A GOOD BOY!” she said just before having a titanic orgasm, sending shivers all over her muscular body.

“Now l want to ride this fucking pole. Lay on your back.”


She then grabbed his cock and squatted on it with one powerful move. Every muscle on her legs flexed and pumped as she came down lower and lower, taking more and more of the mighty phallus inside her dripping pussy. She wasn’t able to take the whole thing, but she managed to get 3/4 inside, which felt better than she could ever dream. She rode him for about an hour, her huge boobs bouncing up and down uncontrollably. His cock was pushing against her brick-like abs while it was inside, fighting for space inside her mid-section with the load of cum inside her stomach and the abundance of muscles she now had, including her abs, obliques , and her pussy muscles. She loved feeling his cock stretch her torso, punishing her for being such a whore as to drink all of his cum, making less space for his humongous cock. She came again and again, but didn’t stop riding him for a single second. She played with her nipples and sprayed the young stud with her milk while she came. He returned the favor by cumming inside her every time, making the tight space inside her even tighter. While some of the cum leaked out, most of it remained inside the muscle goddess as her inside stretched more and more, giving her both immense pain, but also immense pleasure. When it was done, she was visibly bloated with cum, but still her muscles could clearly be seen.

“Phew, that was intense. Squatting on that fire hydrant for an hour while also being filled to the brim with cum felt sooooo good. Damn, I’m such a dirty whore. Well, now I’m a jacked dirty whore!” she said as she flexed her arms, feeling proud of herself.


“Ok. Why don’t you take the lead? I’ll lay on my back while you fuck the living hell out of me.”

She did just that: she got on her back at the edge of the bed and spread her amazonian legs, inviting the muscular stud inside her once again. “Also, don’t forget about my ass.” she said with a wink, flexing her enormous glutes at the same time.

Kevin grabbed her by the ankles and inserted his cock inside her pussy with the force of a cannonball. He stuffed her with 3/4 of his cock for a while, then decided he could push even further. He grabbed her round and muscular butt cheeks and pulled them closer, while also flexing his tree trunk legs and pelvic muscles to push his mighty rod deeper inside a moaning Madison. She felt his cock deeper and deeper and it hurt like hell, since she now had a ridiculously large amount of cum inside her from before. As he pushed deeper and deeper, cum started to come out of her mouth. There was simply not enough space inside her. She felt sorry that she couldn’t hold on to it all while also taking more of the giant cock, but decided that is was better to let some of it go. After she puked a quarter of the cum out, she was able to take 4/5 of his cock inside her. That was as far as her body would go in this state. He pounded her like this for 2 hours straight, cumming inside her regularly, pushing her new body to it’s absolute limit. She had to puke the old cum out a few more times during the long pounding to make new space for the new one. She was very happy to do so.


“I’M CUMMING AGAIN, STUD! DON’T STOP! KEEP FUCKING ME!! KEEP FILLING ME UP WITH YOUR CUM!! I’LL PUKE IT OUT SO YOU CAN COME AGAIN INSIDE ME!! GOD I’M SUCH A FUCKING HOPELESS WHORE FOR THAT HUMOGOUS COCK!” screamed Maddy at the top of her lungs while the jacked stud kept stuffing her with his enormous cock and cumming like he was possessed.

“Let me feel those massive pecs while you fuck me!” she said while grabbing the titanic slabs of beef on his chest, squeezing his nipples hard and feeling his manly pecs as they were bouncing again and again with tremendous force right before her eyes.

“Flex your arms for me, Kevin! Show me those bowling ball sized biceps in all their glory!”

He let go of her legs and hit a double biceps pose. He looked like a god. Every muscle on his body was pumped, but now he was concentrating of his huge biceps. Veins erupted all over his godlike physique, going from the peak of his biceps to the end of his forearms, from the bottom of his muscled neck to his perfect steel abdomen. His biceps were so pumped they made her head look tiny by comparison. Also, his gigantic triceps completed the image beautifully, making his arms look even bigger, stronger and manlier than before. He never stopped fucking her during the flexing, of course. He continued to pound away at his mistress’ pussy and came again from the sheer intensity of his flexing combined with the tightness of Maddy’s pussy muscles around his cock.

"YES!!! GOD, YES!! FILL ME UP AS YOU FLEX THOSE GIGANTIC MUSCLES!!"


Without saying a single word, he grabbed her by the torso and flipped her on her belly. He then spread her asscheeks wide and inserted his dick inside Maddy’s asshole. “You learn fast.” said the girl, a little surprised, but also very perfectly fine with this course of action. “DAMN, YOU’RE STRETCHING MY POOR ASSHOLE TO IT’S LIMIT, STUD. KEEP GOING! KEEP PUNISHING MY WHORE ASS!!” He kept pounding away at her ass for about an hour, smacking her butt cheeks rhythmically, turning them both red when he was done. Her ass quickly filled with pre, but he kept on thrusting harder and harder. He came a lot in her asshole too, giving her anal orgasm after anal orgasm until the inside of her asshole was a mess of pre, thick cum and pulsating internal muscles which were stretched beyond imagination. This perverted combination finally managed to satisfy Maddy, at least for now. When he was done, he took his cock out of her ass and cum started to leak out. She immediately tightened her asshole, preventing the cum from escaping. “That stays with me. I’m not done growing, as you can imagine, and your cum will surely provide me with plenty of protein to get this body in even better shape.”


After they were done, she deemed Kevin worthy of some rest. That, of course, after he cleaned up the place. The bed and the surrounding area were a mess. They were both amazed that the bed didn’t break from the sheer intensity of their fuck session. While Kevin was cleaning the place up, Maddy had an idea: they could make a lot of money if they filmed themselves while they fucked. So she ordered the best 4K camera she could find on the internet, some nice new lights and a few other things she deemed important to make some high quality porn. She then made an onlyfans account under the name “Maddy The Muscle Queen”. She was now confident enough with her body to make a few movies, maybe even more than a few. Of course, this was only the first step of her transformation. She wanted a lot MORE. But first, she had to make some dollars.

Great story and I hope she will get bigger than him.
