She gets conquered

Those two words from Heather hung in Adam’s mind for a split second as he processed it. Just two hours ago, he’d been a skinny guy, having just left gym class. He could scarcely believe that in such a short time, those pills he’d found on the internet had led to the current scenario. Heather had turned around and presented her ass, still clad in the skirt and sculpted from a combination of years of work in the gym, a strict diet, and the incredible effects of the Growth-X pills, and began to grind up and down the obscene length of his dick.

“Please, Adam, fuck me!” she moaned again. “I need this huge fucking cock inside me!”

The Growth-X formula flowed through both Adam’s and Heather’s bloodstreams, changing them inside and out, but it was far from finished running its course. While the immediate effects were obvious, the majority of the changes that happened to both the two of them were beneath the surface. For one, it had cranked up Heather’s libido even higher than it had been before, leaving her lusting for Adam’s newly gigantic cock like there was no tomorrow.

“Please…” she continued, running her hands down the smooth roundness of her huge ass.

“Heather…” Adam groaned back. Just like the busty Latina in front of him, his libido had also gone through the roof, and it took every bit of his newfound strength to refrain from grabbing onto her wide hips and shoving the entirety of his cock into her sopping-wet pussy.

Heather took a peek over her shoulder at Adam, once again taking in the enormity of his fuckpiece along with his two huge nuts. It was so thick… she wondered just how potent the jizz stored in those bloated balls of his was.

“I’ll fuck you until you can’t walk!” he said, finally giving in to what his dick was telling him to do and placing his hands on either side of her ass. “Slut.”

Heather moaned as she felt the thick crown of his dick tease her slit. “So fucking big…”

“And you’ll take it all, Heather,” Adam grunted as he pushed his hips forward, pushing the fist-sized crown through her right cunt. “How long do you think it is?

“F-fuck, eleven inches? Twelve?” Adam’s dick was barely inside her but Heather was already in ecstasy. She’d never felt like this with anyone! Of course, none of the boys she’d been with were packing nearly as much as Adam was. In fact, she wasn’t sure if anyone in a 100 mile radius came remotely close to packing as much as he was…

“If you’re so unsure about it, then maybe you’ll have to measure it after I’m done fucking you!” he said, leaning closer to Heather’s ear and pushing three more inches of his schlong into her pussy. Adam’s arousal continued to climb, and to the busty Latina’s surprise, she felt his cock, already fit tightly into her pussy, thickening.

“Fuuuuck..” she moaned. The feeling of Adam’s growing dick pushed her over the edge, and her first orgasm (though it would be far from her last) from his ginormous cock slammed into her like a tsunami. “I need it ALLLLLL!!”

“Heather, you sizequeen WHORE!” Adam roared back. The Growth-X had already changed him mentally, and he realized a few things at once. First off, not only was he fucking Heather, one of the hottest girls at school, she was begging for his cock. Second, and more importantly, he realized that he was THE alpha male. There was no way that a stud like him would ever not be surrounded by huge titted sluts, all ready to service him at a moment’s notice.

It was evident that Heather agreed with this, as she moaned and squirmed on top of Adam’s prick, struggling against his powerful arms to take yet more of his dick. “Fuck me, you stud!” Adam was more than happy to comply with that request, feeding the rest of his forearm-thick fuckpiece into Heather’s slick cunt and coaxing another orgasm out of her, causing her to spray her girlcum. “Breed me, you fucking stud!” she wailed.

Adam settled into a steady rhythm, pulling his hips back and slamming the rest of his cock back into Heather’s pussy in a series of brutal eight inch thrusts. “I’ll do more than just breed you, you disobedient slut! Taking those pills without my permission…” He smacked her ass.

“Punish this naughty whore, Adam! Fuck me and empty those huge balls into me!”

SMACK!

“Just imagine if I’d taken the rest of the pills, Heather.”

SMACK!

“Imagine how much more alpha stud COCK you’d have up your pussy if you hadn’t taken them.”

SMACK!

“I’m sorry, Adam! Fuck MEEEE!!!”

“What was that, Heather?”

“Let me be your personal cocksleeve, you megadicked fucking STUD!!”

Adam’s **** on the big-titted Latina’s pussy continued, his powerful hips thrusting forward to fit as much of his own ginormous dick into her as possible. His full nuts slapped up against Heather’s thighs with each thrust, and she moaned when she felt his enormous fuckmeat enter her once again.

Adam was no ordinary man, Heather realized. No, he was far more than just a man. He was 100% pure alpha male, his virility matched by no one, and she knew she wanted to worship him and his cock for as long as she could.

The pressure in Adam’s nuts was building fast, and with each thrust, he came closer to blowing his load inside the tight confines of his new cocksleeve’s cunt. “You’re one lucky slut, Heather,” he groaned, straining to hold his load in for as long as possible. “If you weren’t such a hot, huge-titted whore, I might have to punish you even more!”

“Your huge-titted whore wants you to flood her pussy and claim her!” she moaned breathily.

Heather’s pussy finally pushed him over the edge, the tightness finally coaxing an orgasm out of him. Adam’s grip on her hips strengthened as he pulled her all the way down on his massive dick, hilting himself before he tensed up and began to cum.

“Take it all, you slut!” Adam roared, firing an impossible amount of his Growth-X augmented jizz deep inside Heather’s pussy.

“So...much...cum…” she moaned, her body reacting to the potency of his thick seed. While the direct dose of the pills had been effective, it was nowhere near as strong, nor as fast-acting as the cocktail that was Adam’s Growth-X enhanced cum. The pleasure overtook Heather’s mind for a split second as she felt him continue to blast his load into her cunt. In seconds, Adam felt the cheeks in his hands expand outwards before he looked up to see her tits growing too. “Holy fuck Adam, I’m yours.”

“I know you are, you slut,” he said, rising up to his full height as he began to extract his cock from her cum-flooded pussy. He noted his new height, a towering 6’6 to compliment his new physique, which had become further improved and defined. Each slab of muscle rippled powerfully when he moved, from his thick arms to his abs to his legs. The only thing that Heather cared about, however, was his manhood. Similar to the rest of his body, his cock and his balls had grown, and she’d found a ruler somewhere in an attempt to measure it. To her delight, Adam’s dong dwarfed the measuring tool, the tip of it extending some six or seven inches past the end of it.

“Huge fucking cock...” she said, putting the ruler down and leaning forward in an attempt to once again suck his monstrous fuckstaff. Instead, the Latina’s head was stopped short by one of Adam’s hands.

“Naughty nympho bimbo…” he groaned. “Before you get to suck this dick, you’ll have to take it up your slutty ass!”

“Fucking claim my ass, Adam!” Heather backed off and bent over his desk, presenting her fat bubble butt to him. “Fill it with your huge alpha bull cock!”

“I’ll do more than just fill your ass with my dick,” he snarled, his large hands finding their way back to her hips. “When I’m done with you, you’ll be ruined for any other cock.”

“I’m already yours and yours only!”

“That’s a good sizequeen bimbo.” Adam said, beginning to spread Heather’s asscheeks apart before he squeezed his ultra-thick cock in the valley of her booty. “How bad do you want it?”

“I’d do anything for you, Adam! Anything for you to dominate me as hard as you can and shove that gigantic fucking DICK up my ass!!”

“Is that so, Heather?” he **** the tip of his cock through her bung, much to her delight. “Anything?”

“Anything and EVERYTHINGGGGGG!!!” she began to scream as she felt more of Adam’s cock enter her through her tightest hole, its incredible girth stretching her far beyond what she thought possible.

Adam thrusted three more inches of his Growth-X enhanced cock through her ass, her walls hugging every vein-ridged bit of dick that she could as she jerked upwards and fired a gusher of girlcum in yet another orgasm.

“Is my phat Latina ass a good enough sheath for your massive fuckpole?” Heather moaned. Adam’s cum had completed her transformation, in both mind and body, into a complete bimbo whore, and she could think of no better way to spend her time than worshipping the man with the biggest dick she’d ever seen. “What do you say, Adam?”

“I think you’re a phat-assed bimbo whore,” he said, noting how Heather perked up when he said that. “And phat-assed bimbo whores like you have one job: to service alpha studs like me. Do you understand, whore?”

“Yes, Adam! Your phat-assed bimbo whore understands!”

Adam surprised Heather into moaning loudly by doing two things in quick succession: first, he thrust four more inches of his cock into her, then he wound up and spanked her booty, watching it jiggle for a split second. His gaze lingered for another moment, taking in how firm her huge ass was. “What did you call me?”

“A-Adam,” Heather responded unsurely.

“You naughty slut!” a nasty grin spread across Adam’s face. He spanked her again. “What do you think you did wrong, Heather?”

“I don’t know…”

SMACK!

“Yes you do, Heather.”

The Latina minx laid still, still bent over the desk as she thought. “I called you Adam?”

“That’s right. And what can you do to fix that?”

“I-” Adam cut her off by spanking her once more. “I don’t-”

SMACK!

That spanking suddenly made everything fall into place for Heather. If she was going to submit to Adam and his massive fuckstick, she’d have to do it all the way. “You’re my…” she started.

“Go on,” Adam encouraged her, one hand on her ass and the other raised up, prepared to spank her.

“You’re my MASTER!” Heather moaned. “And I’m your submissive little nympho minx! I’ll suck and fuck your huge horsecock whenever you want!”

Adam rewarded her by thrusting all the way forward, fully entrenching himself inside of her booty. Once again, Heather’s back arched as she felt multiple orgasms rip through her oversexed body, her juices spraying from her pussy in every direction.

“Oh God, fuck me! Fuck my slutty ass as hard as you can, Master!!”

The muscular stud behind her groaned in response, firing a blast of precum into her bowels as he began to fuck Heather in earnest, her massive ass rippling each time Adam’s powerful hips came crashing down on her.

“Oh fuck, MASTERR!!” she wailed as he brought her to new levels of pleasure, each thrust more powerful than the last. “God, if only you had two giant fuckpoles to really tame me into your mewling submissive bitch!”

Adam spanked her once again, eliciting another sexy moan from her.

“Fuck, I’ll have to tell my other sizequeen friends about you, Master!” she said between gasps for breath. “I bet Natalie, Amy, Mina and your sister Sarah would love you!”

“Sarah?” Adam said, slowing down at the mention of his sister.

“God, it would be so hot to see you tame your sister into a bimbo like you did to me!” she moaned. “Seeing my alpha stud daddy breaking all the taboo to ruin each and every one of his sister’s slutty holes…” she continued dreamily.

That one sentence was enough to send Adam into a frenzy, and he upped his pace twofold, sawing his cock in and out of Heather’s ass as fast as he could and turning her into a screaming, moaning, and squirting mess. “Fucking BIMBO WHORE!” he roared, feeling his own orgasm rapidly approaching. In a flash, Adam shot his load into Heather’s booty, jet after jet of hot Growth-X jizz streaming out of his dick and into her ass. “CUM DUMPSTER SLUT!”

“FILL ME UPPPPP!!!”

It felt like an eternity had passed by the time he finished jizzing, but Adam, much to Heather’s dismay, began to extract his dick from her ass. “You naughty little minx!” he said once he got his cock all the way out of her heavenly ass, seeing the excessive amount of jizz dribbling out of her. “I bet a cock-hungry slut like you has dozens of dirty ideas just like that, don’t you?”

“I do,” she replied. “But I won’t tell you, Master!”

“Then I guess I’ll just have to fuck them out of you!” Adam picked Heather up, noting how light he felt in his thick arms, and carried her over to the bed where he set her down on her back and straddled her. “I’ll teach you not to keep secrets like that from your stud!”

“Please do, Master!”

Adam moved his focus to her tits, which sat high on her chest despite their massive size, and laid his schlong on her torso, the weight of it and its heavy musk causing Heather to gasp. “I’ll fuck your tits,” he started. “And you’ll get to taste your ass off my cock.”

“Sounds like a win-win to me.” Heather replied, letting Adam’s incredibly thick dong slip between her own mammoth boobs. Even with the immensity of her huge melons, there was still a good portion of his dick peeking out, including the fist-sized crown that was dripping precum onto her chest.

“Horsedicked alpha stud…” Heather whispered as she began to move her tits around Adam’s dick, and he responded in turn, thrusting through her cleavage so his dick got close enough for her to taste. With each push, Heather’s tongue came out, and she licked the tip of his dick.

“So, Heather,” Adam said. “Are you ready to tell me your secret?”

“Fuck, Master,” she replied. “Yes!”

“Tell me.”

“God, since you’ve fucked me so hard and you came so much in my pussy, there’s no way you haven’t gotten me pregnant,” she said. “Fuck, you probably gave me twins, you stud! And they’ll be busty, slutty, and just as cockhungry as me!”

Adam grunted and blasted her face with precum before he registered what Heather had said. Come to think of it, he remembered reading on the bottle of Growth-X that one of the side effects was that it would result in nearly all offspring produced by the one who took it being female…

“And I bet both of our girls will be more than happy to serve as your personal cocksleeves just like me when they’re old enough to! Just imagine, me and our two sexy daughters wrapping our huge titties around your ginormous cock, three submissive Latina bitches to your alpha maleness!”

“God, Heather, you’re a dirty nympho whore, you know that? And you know what dirty nympho whores like you deserve?”

“The biggest cumshots from the strongest alpha studs?” she responded.

“That’s right.”

“Then fucking jizz all over me, Master!”

All it took was two pumps of his massive cock to push Adam over the edge, causing him to let out a guttural roar as he unloaded the contents of his nuts onto Heather for the fourth time. There was no way that the Latina’s gorgeous face would be able to take the entirety of his cumshot, and she opened her mouth after a few seconds, welcoming in the incredible girth of his dong as Adam stuffed it in to deposit the rest of his load deep within her stomach. While this fourth load was not quite as impressive as his first three, it was still far more impressive than any other man would have ever been able to muster, a fact that made Heather moan as she swallowed as much of Adam’s seed as possible. By the time that he finally finished emptying his nuts into her, she laid on the bed with jizz covering her face, leaking out of her ass and pussy, and filling her stomach. In fact, the last load had been so large and so thick that Adam could make out a slight bulge in her normally-toned stomach, clearly a result of her swallowing so much of his cum.

“Oh, Master, you’re so fucking virile,” Heather moaned. “You could fuck me all day, every day, and I’d never get bored! Imagine if you had more of those pills...”

“Don’t think I’ll still let you off easily for taking those pills, Heather.” he said, his voice a low rumble. “I think the perfect punishment for a cock-hungry slut like you is simple: you don’t get to suck or get fucked by me for now.”

“Master, no! I need your cock!”

“You’ll be fine, Heather. It’ll only be a few hours.”

The dark-haired slut begrudgingly accepted her fate as Adam walked over to his desk and opened his laptop. To his surprise, he had an unread email from an address that he didn’t recognize.

Hello Adam,

You recently ordered a bottle of the experimental Growth-X pills from me, and I can’t thank you enough for that. I have selected you to participate in a trial of a similar ****, if you are willing to participate. If you are, could you meet me at my lab on Friday afternoon?

Thanks,

Amelia

There was an address at the bottom. Adam mulled it over for a moment. If he’d been asked the same question a day ago, the answer would’ve been the easiest “no” of his life. Today, however, was different, especially since what he would be testing was similar to Growth-X. Furthermore, it wouldn’t even be a hassle for him since it was so close. “Fuck it,” he said, standing back up. “Heather, stay quiet in here. If you’re a good slut then I might fuck you when I get home,” he said before he left the room.
