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.
