Maddy opened the metal briefcase and removed one more syringe that was filled with her MGE-2 formula. She licked her lips and slowly approached the 2 giant studs. Without a moment of hesitation, she inserted the needle in the biggest throbbing vein she could find on her left arm. She emptied the entire serum into her system then threw the syringe away in a random corner of the large room. “Fuck!! I can feel it in my veins. It’s gonna make me bigger. YES!! I’m gonna get ever better! Even hotter! FUCK YES!!” said Maddy as she felt her body starting to burn from inside out. Her muscles started to swell with every second, gaining more mass and more definition. Her juices started flowing without control, covering her growing thighs and slowly dripping on the floor below. Her tits started to lactate like broken faucets, growing larger and rounder as more and more sweet nutritious milk came out. The boys couldn’t control themselves as they witnessed Maddy’s growth and began to stroke their massive shafts. She knew that her transformation would take at least 15 minutes, which meant she’ll have to endure both it’s pain and pleasure for a while. Drool was coming out of her mouth and tears came out of her eyes as her body packed on more and more muscle with every second.

“FUUUCK! IT HURTS SO MUCH... BUT ALSO FEELS SO GOOD!! I NEED MORE... MORE PAIN... MORE PLEASURE!! FUUUCK!! GET OVER HERE!! BOTH OF YOU! FUCK ME!! BREAK ME!! I WANT TO GET DESTROYED BY THOSE MASSIVE COCKS WHILE I GROW BIGGER AND BETTER THAN EVER BEFORE!!” screamed Madison as she couldn’t take her eyes off the huge cocks in front of her while squeezing her rock hard nipples with both hands. The boys were ready to comply. Kevin grabbed Maddy from behind using a full nelson to lift her up. She felt his massive chest pushing against her growing back while his titanic arms kept her in place high above the ground. She felt his bulging biceps flexing behind her as her own arms increased in size. She wasn’t sure what they were planning, but the growth was still a long way from ending, so she her mind couldn’t really be bothered. She just wanted cocks. Huge cocks stretching her swelling body. Kevin kept her up in a full nelson and inserted his mighty rod inside her asshole with a powerful thrust. He flexed his strong glutes hard, trying to push all of his throbbing monster inside her gaping asshole. On the other end, Tyler lifted her legs up and positioned his big black meatpole at the entrance of her squirting pussy. He began to pound away, pushing his monster cock deeper and deeper with every thrust. She was now getting double penetrated by the most muscular men on the face of the earth. Their humongous cocks punished her pussy and ass with the power of two industrial hydraulic presses. The feeling of being manhandled by two massive studs filled her mind with lust. She loved the feeling of their hulking bodies making contact with her own. Getting slammed by their hard balls as they fucked her with all their might pushed her to new levels of pure ecstasy. She loved getting impaled on their massive veiny fuckpoles as they leaked precum into her slutty holes. As one of them pushed his cock inside one of her holes, the other pulled out. They worked in a perfect rhythm without even realizing, stretching Maddy’s magnificent growing body, fucking her into oblivion like the true alphas they were.

“OH MY FUCKING GOD!! IT’S SO MUCH COCK!! I’TS STRETCHING ME OUT!! MY PUSSY AND ASS FEEL SOOOOO GOOOOOD!! I’M GONNA LOSE MY MIND!! FUUUUCK!! MORE!! PUNISH ME MORE!!! USE YOUR FAT DICKS TO RIP ME APART AS I GROW EVEN BIGGER!! FILL MY SLUTTY HOLES WITH YOUR CUM!!!” screamed the girl at the top of her lungs while her muscles swelled bigger. They fucked her like this for the next 15 minutes. She screamed and came non stop, coming very close to losing her mind for good from all the intense pounding she was taking. Around them formed a large puddle of squirt, precum and milk. The puddle became so large that it reached 10 meters away from them. Two blonde maids began to lick the incredible mix from the floor, trying to contain the mess as much as possible. Needless to say, the floor was cleaner that a doctor’s office and they were just too horny to resist. At the 15 minute mark, Maddy’s transformation was close to it’s end. The boys sensed it and began to pound her at the same time, filling her slutty holes with all of their meat at the same time. The final growth spurt was by far the biggest, sending her entire body into a frenzy of physical and psychological delight. Her muscles exploded with size one last time, pumping themselves even bigger. She flexed every single muscle fiber in her godlike body at the same time, pushing her mind over the edge: “FUUUCK!!! THIS IS IT!! MY BODY IS SO PACKED WITH DELICIOUS MUSCLES!!! I’M GONNA FLEX THEM ALL AT THE SAME TIME!! I’M GONNA CUM FROM FLEXING MY PERFECT PHYSIQUE!! YEEEEES!!! FUCK ME!!! DON’T STOP!! I’M HAVING A MUSCLEGASM!!! FUUUUUCK!!!”.

She felt her mind drifting away as she had the most intense orgasm of her life. She came like a volcano from flexing her growing muscles while her musclebound boys fucked her holes into kingdom come. Her massive tits sprayed milk with the force of fire hoses as they were still growing larger and her pussy practically drenched the boys in its juices, spraying like a broken dam. As they felt their mistress cum with such force, the boys couldn’t take anymore. They pushed their massive rods all the way inside her and exploded at the same time. She felt the two giants cum inside her and had a second massive orgasm, even bigger than the musclegasm before. She screamed louder than ever as she buried her nails in Tyler’s massive chest, most likely due to some king of primal instinct. They came more than ever before, pumping massive loads of cum inside her spasming muscular body. There was so much that it started to flow around their cocks out of her. She felt her body struggling to contain all the semen inside as her belly bloated to insane proportions. Her eyes rolled back inside her head as her screaming stopped.

The boys pulled their dicks out after they were done releasing their potent seeds. They came enough to easily fill an entire bathtub with their combined loads. Her holes were pulsating and cum was flowing out. They looked at one another, but Maddy wasn’t moving. Kevin released his full nelson and wanted to place her on the bed, just like before. As he carried her over to the bed, she sprung back to life. “FUCK!! That was intense!!” she said as she jumped out of Kevin’s arms and onto her own feet. Her huge belly was almost gone, leaving behind her insane abs, now bigger than ever. Her body somehow absorbed all the nutrients from the semen in just a couple of minutes, using it as fuel for her recovery. “Damn, boys! Check me out!!” she said as she started to flex in front of a large mirror. Her body was beyond amazing. Every muscle on her frame was bigger and harder and her tits were now the size of beach balls. Her ass was rounder too, by far the best in the world in both size and looks. She was easily bigger than any Mr. Olympia could ever dream, packing on insane amounts of pure muscle all over her frame. But she retained all of her feminine beauty and finesse. She was now 6 foot 6 inches tall and about 300 pounds. Her meaty lips also seemed to grow slightly bigger, as well as her eyelashes.

She flexed in the mirror for a couple minutes to fully take in her improved body. She felt power flow through every large vein on her body, from the peak of her monolithic biceps to the last inch of her massive calves. She flexed her biceps, pumping them bigger, kissing them both. Then flexed her massive chest, feeling her massive slabs of pec meat pump up and her enormous boobs rising higher. She grabbed them and felt them with her powerful hands. They were so soft and so full. She began to squeeze her nipples. She felt milk coming out and wanted to drink it, but was unable due to the sheer size of her boobs. She then squatted in front of the mirror and began to play with her cunt. She flexed her muscular legs as she fingered herself. She was getting off watching her massive legs explode with size as she continued to flex them, harder and harder. Eventually she came, squirting hard all over the mirror. “Fuck! I’m such a pervert I’m coming just from flexing my muscular body!” she said as she licked her fingers which were soaked in her juices. She then got up and walked towards her muscled studs.

“So what do you boys think?” she said with a wink while doing a double biceps pose. “You look incredible! You’re by far the most beautiful and hottest woman on the planet.” said Tyler as he marveled at her perfect curves and wonderful face. Kevin approached her and kissed her hard, bringing his big tongue inside her mouth. He then grabbed her ass with his strong hand, bringing her closer to his massive chest. He wanted to feel her next to him, feel her entire godlike being. He was a hopeless romantic after all. “How’s that for an answer? he said after he was done with the kiss. "I think I’ll take it.” said Maddy with a proud smile on her face, feeling his rock hard abs.

She walked towards the briefcase and took out the last vial of the formula. “So, we have one more left. I don’t know about you boys, but I’m still horny as hell. And I’m up for some really hardcore shit.” said Maddy as she walked towards them with the syringe in hand. They both got hard instantly. “I see you agree.” she said as she licked her lips. She got on her knees and examined both cocks closely, from the tip down to the huge balls. Precum started to drip slowly from their cockslits as they waited with anticipation. “God you boys are sooooo big! But I think we can go a little further!” she said as she looked up at them while holding their monster cocks next to her cheeks. She then took the syringe an inserted it into the great vein on Kevin’s cock. She pushed the half of the serum into Kevin’s dick, then did the same for Tyler. “Now let’s see how that plays out.” she said with perverted look on her face.

The boys started to moan and grunt. They both grabbed the base of their cocks with both hands as their already monstrous rods started to grow bigger. Precum started flowing faster as Maddy watched their cocks expand. They both grew 3 inches in length, Kevin now sporting a 20 inch dick and Tyler a 18 inch one. Both of them got 20% thicker as well and their balls expanded by about 10%. Since they were injected with only half a dose, their muscles didn’t grow a lot, but it was still an impressive sight. In a few minutes Tyler added 30 pounds of muscle mass and 1 inch to his height, now being 415 lbs and 7 feet tall. Kevin was now 375 lbs and 6 feet 10 inches tall, adding about 25 lbs of pure beef and 1 inch in height and also improving his vascularity. They both got larger overall, looking like gods among men, ready to decimate legions of hot women with their giant dicks and imposing muscles. Maddy watched with satisfaction as her boys grew bigger and hotter with every second. She played with her wet cunt and with her enormous tits, waiting for the transformation to end. After a few minutes, it did. The growth stopped and the boys came hard, covering Maddy in insane amounts of their seed, making her cum as well.

“Shit, boys! You came buckets!! Look at those humongous fucking dicks!! And your cum smells so good... and tastes even better!! Now you really got me in the mood!” she said as she tried to lick the cum off her face and tits. She got up, took their hands and walked with them to the center of the room, near the largest bed and the pool. “You know what, we should not keep this fuck marathon just for ourselves. We should share it with our fans! Hey girls, bring the cameras in here! We’re making the best porno ever right fucking now!!” The maids that were licking the fluids off the floor got up and rushed out of the room to obey the mistress’ command. In less than 10 minutes everything was ready. The 2 maids were joined by Amanda. They set the cameras and the lights as Maddy was on her knees with a monster cock in each hand, waiting for the signal to begin. ”Yeah boys, we’re gonna paint this entire fucking room with your cum. We’re gonna fuck until none of us can stand anymore!” she said as she gently stroked the huge veiny cocks. She decided that this time they will be live streaming the entire fuck session directly on her account. She was ready to fuck those muscled studs for hours without a single break and wanted every one of her fans to see it. Amanda gave the signal and the cameras started rolling.
