"For your transformation, you'll grow to a towering 8 feet tall. Your whole body will become more muscular, and your cock will become enormous, almost too big for any human but I will be able to take it all in with enough effort without bad consequences." Jen spoke and climbed on top of his cock and started grinding, her pussy juices flowing to his erection. "Your balls will grow to match and have 10x as much cum as normal, and be able to produce multiple times in a row. You will be full of muscles, and have a dominant instinct like never before."
She slowly slipped just the tip inside of herself, moaning as Mike tried to push himself even deeped inside lifting his hips as she resisted. "Jen... Babe..." He begged with his eyes and stuttered in pleasure, dying from anticipation. "Your cum will be potent and fertile, and will also fill my body fully and completely, making me huge." Mike barely had time or the brain power to process all the words she spoke, only getting more and more lost on the pleasure as time went by. Jen lowered herself a inch or two. "And for your dare... I dare you to Transform or Dare me into anything you desire! That is... After you fuck me GOOD!"
As she finished the statement, Jen rose up her hips and slammed back down taking his entire cock inside all at once! Mike could swear he was about to cum, but the pleasure just kept building on and on alongside a warm tingly sensation. She was getting even tighter, and everything was shifting ever so slightly. Jen could feel Mike's cock pulsing and growing inside of her, inch by inch, longer and wider too, straining her insides to the limit and making her a mess as the waves of pleasure built and built. She could feel him swelling larger than anything she ever taken before, likely already going over 10 inches. Not only that, but Mike's head hit the bedstand and his chest rose up as his pecs and abs tightened up more and more by the second.
His body radiated heat and power, as he grew more and more in both height and muscles. Veins started popping up in more places around his neck and on his arms, growing stronger and holding onto Jen ever tighter. "Mike... Mike wait! Maybe this isn't such a good idea..." Jen got a tiny little bit desperate, as she felt his cock growing more and more with each second. Mike's grip on Jen's hips, with his enlarged hands and arms, was a desperate and dominating one that made Jen squirm in both fear and excitement as she struggled to move and even somewhat breathe while trying to escape. Mike moans and groaned feeling how much his cock filled his girlfriend and how big he was becoming. "Mike please... let me just readj-UUUST!" Mike lifted her up in a instant, but on the next he just slammed her down again, his cock fully inside. Jen cried in pleasure as his cock head reached the uterus wall and started creating pressure. What should've been pain only turned into more and more pleasure, and as he rose her up almost to the very top and then back down again all at once, he penetrated her womb almost effortlessly. She screamed and moaned lowdly in pleasure as her orgasm came crashing down and her mind went blank. Now a bulge was visible from her lower abdomen and became ever more present as the seconds ticked by.
"Holy fuuuuuck" was all Mike could mutter at the rush of pleasure that rippled through his body as Jen could only babble, stutter and moan. Her body trembled and twitched randomly as the shocks of lust coasted throughout in waves at every little movement from both his gigantic cock and his massive hands that now completely wrapped around her waist and ample hips. She seemed to be so much smaller then him, with Jen having the feeling of grinding the cock of a demigod. He now saw Jennifer as such a fragile yet wonderfully lustful... Object... The bed creaked with the increased weight and Mike moaned in delight by the overwhelming stimuli all around: His increased strength, height and adrenaline alongside the absolute seal on his cock and the pure raw power he felt coarsing through his body were all too much to handle. Not that neither of them noticed or would care, but he did finish becoming a 8 feet tall bodybuilder with a 2 foot cock 10 inches wide and massive balls. The bulge on Jen's stomach stuck out much further than before, now his entire head palpable from the outside.
"Jen... Babe I want more... I wanna fuck you... Now..." Mike's look of pure hunger and lust made her feel like a defenseless pray, who fell into the big bad predator's trap and was staring into its open mouth ready to bite down. But what really made her almost regret all her life choices was when Mike picked her up to lift from his cock again "Wait mike mike MIKE MIIII-"! She screamed in wonderful blissful pleasure as, inch by inch, the monster cock slipped away. Her legs spread wide apart as the thickness pushed the pussy walls and even a bit of her hips to the extreme. Jen trembled all the way up, as Mike groaned and screamed, kneeling her hips and gripping her tightgly, increasing how much tighter she really was around his cock. "Ahhh... Ahhh! Ahhh! Miiiiike!" She couldn't even process what she really wanted, as yet another orgasm reached as soon as his cock left her womb, then another one right afterwards as the very top popped off outside. The bed drenched in juices as much as their genitals, and Jen went limp on Mike's hands. He still wasn't satisfied, though...
"Uhghh... Mike?" Jen woke up confused with a mountain on top of her. Mike had placed her down onto the bed while passed out and now he was lying down on top of her, practically drooling, rock hard and lined up. Towering over her, Jen felt like she had shrunk just as much as he had grown, as his chest was as big and wide as her entire torso, and his arms seemed like the size of her own head. It brought a feeling of powerlessness that drove her instantly insane. He could break her in half by blinking if he wanted to. And he was rearing to go.
"Jen... I'm gonna breed you now, okay? I can't wait anymore..." His voice brought shivers down her spine as she crumbled and folded like a little rabbit under his charms and might. "Yes babe... Fuck me!" Jen spread her legs using her hands, as she was too tired to move from the waist down, and waited on Mike to make a move. But... He didn't... "Mike, please babe... I want you so bad!" "Then beg... Slut". He had never called her a slut before! It was something they had discussed that Jen enjoyed, but Mike wasn't all that confortable (or even that good) doing. Which was okay, but now... That look on his eyes didn't lie. He meant it, truly and lustfully, and Jen was more than happy to oblige. "Please, I need you to fuck me! I'm your dirty slut, please fuck me hard!!"
He pulled on her hair with hands that could wrap around her face and tugged - carefully but still causing a stinger of pain, the good kind - and Jen moaned in delight as she felt his cock head penetrate ever so slightly. "You like it when I play tough guy with you, you horny slut?" His whispers sounded much deeper and rumbled her entire being to the core with how he was treating her. "Yeeees... I'm soooo horny for you babe... I love it!" "Then say it, and louder... Say 'Im a dirty cumslut, breed me daddy', reaaaal loud now" He bent down so that he could whisper in her ears, licking and kissing all the way down her cheeks and neck, and started to bite down. "I'M A DIRTY CUMSLUT, PLEASE BREED ME DADDY!" She screamed wide eyed as her hands traveled across Mike's muscular back and scratched, twitching and trembling trying to insert more and more of his cock inside but Mike was still not moving deeper. "Louder!"
"PLEEEEASE MIKEY DADDY, BREED ME AND PUT YOUR CUM INSIDE OF ME! I WANT ALL OF YOUR DELICIOUS MONSTER COCK INSIDE MY PUSSY! I WANNA HAVE YOUR BABIES!!!"
In one movement, with pure brute force, Mike hammered his entire 2 foot rock hard cock inside Jennifer's drenched and tight pussy, penetrating her womb and showing a big bulge on her stomach. Her screams didn't register in her own head, as it spun and broke down by the intense and sudden orgasm that currently made her completely unaware of anything other than how his gigantic monster cock was penetrating her body. Mike didn't register anything either as his intense lust overcame his conscious and he slammed Jen out and back in again, repeatedly fucking her out of her mind and body, almost using her like a doll. Neither of them could even speak, only grunt, pant, moan and gasp as the pleasure kept on building and building and building untill the climax came for what could've been the 10th or
110th time for Jen, and then finally Mike cave in.
A flooding of cum occured inside Jen, her stomach bloating out immediately as jizz poured inside her womb. She started getting heavier and heavier as her belly grew past her breasts and started sagging, touching Mike's PACs and covering their crotches. The head of his cock was no longer visible as his cum overflowed inside of her. Jen could feel the hot thick liquid sloshing inside of her, building up a tension as she grew more and more. It was a really intense and absurdly powerful feeling, as her belly pushed out at the size of a full pregnancy and kept on going! She could feel the cum flowing from within Mike's shaft and her legs touched the churning and gigantic balls that burned with heat from his potent cum.
She started to look absolutely gigantic on top of Mike, as her breasts, tights, ass and hips also started expanding. It was as if her body was absorbing his cum in real time as it flowed inside of her! She looked huge, gaining about 150 pounds of cum withing herself before the flow started to slow down and eventually stop. Neither of them were really aware of what had happened, lost deeply in immense pleasure and lustfullness...
