Crawling between her legs, Greg immediately buried his head between Alisson's thighs, kissing his way up the soft flesh of her inner leg up towards her juicing pussy. Cooing encouragement, she ran her fingers through his hair and guided him home, pressing his face against her junction as he opened his mouth to give her a long lingering lick. She tasted sweet, but not cloying, not unlike what he'd drunk from her breasts last night. Locking his mouth onto her pussy, he suckled on the lips and bathed it with his tongue as she writhed and moaned above him from his oral worship. "Oh- t-that's a good fucking boy, right there... drink it all up," she purred, grinding against his face as she leaked a small river of fluid into his suckling mouth.
Greg struggled for breath where he could, her thighs squeezing around his head and encasing him in the low deafening rumble of his distant heartbeat. Swishing his tongue around, sucking on the swollen lips, and nuzzling the small bead of her clitoris he worshipped there, digging his fingers into his thighs as he devoured her cleft like he was gumming on a peach. Alisson thrashed a bit above him, tossing about her head and her taffy-like locks as she bucked her hips up against him, cumming with a quiet mewl and flooding his mouth with more sweet tasting fluid which he obediently drank down. As he drank, he felt his whole-body tingle, and not just from oxygen deprivation - though he was still thankful when her thighs finally released him and allowed him to gasp for air.
As he caught his breath, Greg looked up at her glassy eyed from between her thighs. His heart thundered in his chest, and he felt... strange. His dick was certainly still into this though, and if anything had only grown more perturbed by the lack of attention being shown to it. Alisson smirked and brushed his length with her foot, making him gasp. "You're ready," she purred, crawling backwards onto the bed. "Come to me." Grabbing the edge of the bed, Greg hauled himself up and crawled across the sheets towards Alisson. As he worked his way up her body, he kissed her, starting with her ankles and trailing leisurely up her calves and thighs, around her hip and up her tummy until he reached her breasts. He paused to nuzzle her wonderful tits for a moment, rubbing the stubble of his chin against the sensitive flesh and making her giggle, before kissing her on the neck and sliding himself between her legs.
Alisson reached down between their bodies and took hold of his dick, giving him a light stroke and lining him up with her pussy. But as he tried to ease himself inside, she held on, squeezing him in her fingers and playing a steading hand on his chest. "Greg, how long have we been together?" she asked sweetly, rubbing the crown of his dick with her thumb making him squirm. "W-what?" he asked in an unsteady voice, confused. "Three years baby, why?" Alisson's smirk widened, brushing his tip up and down the moistened entrance to her vagina, teasing the crown with just a taste of the slick heat there and making him shiver. "Three years, don't you think we should take this further? Don't you think we should go to the next level?"
Greg looked at her confused, not in the best frame of mind due to both how hard he was and whatever all that Alisson juice he'd been drinking was doing to his body. His dick throbbed powerfully, wanting only to bury itself into the warm softness he knew would milk him into mindless oblivion. "I want fission," she explained. "I want to divide." This just made Greg even more confused, and he stared at her blankly while trying to hunch his way into the velvety grip of her cunt. "I- you- what?" he babbled, the PAL talk confusing him, especially now with how much he NEEDED to cum inside of her. Alisson grinned and stroked him, keeping him on edge. "Human terms. I want you to make me pregnant. I need your genetic material to reach critical mass and divide. Can you do that Greg?" she asked in a sweet voice, sliding his tip deeper into her vagina. The lips closed around his crown and squeezed, sucking on him like the lips of a mouth. His eyelids fluttered. "Can you fuck me pregnant? Knock me up? Pour all your cum inside of me until I'm full? Can you do that Greg?" She taunted, fingers stroking up and down his length now. He struggled not to cum on the spot.
"If you don't think we're ready, just pull out," Alisson whispered into his ear. This was - extremely unfair, a part of him knew. He wasn't 100% clear on what fission entailed, but he'd heard 'pregnant' and to his mind that screamed trap, extortion, manipulation. His dick, however, did not care. It just plumped up at the very thought of impregnating Alisson, with her sexy curves, with her welcoming body that tapped him dry every night. His manhood screamed at him to plunge inside, to ravage her, to dump every drop of cum inside his churning and over-active balls into her womb or slime core or whatever he had. Alisson blew softly on his ear before biting down gently on the lobe. "Give it all to me, Greg," she whispered, and let him go.
With a bestial snarl, he plunged inside of her, uncaring of the consequences. Alisson cried out in exultant pleasure as he pounded into her with savage abandon, his higher reason taking a back seat to the denied NEED of his over-active libido and the subconscious, primal promise of impregnating a fertile womb. Her legs came up and wrapped around his back, preventing any notion of escape - not that any such notions were in his head. Teased into a primal rut, instead he just selfishly and recklessly plunged into her repeatedly, locking his teeth onto one of her nipples and sucking up the juices that trickles from the chewy teat. He came quickly - and that was a surprise. He was used to Alisson dragging things out, controlling the pace, making sure he didn't cum until she let him. Instead, his body went to cum and he just CAME, pumping a hot thick load right into her as she babbled appreciation and encouragement into his ear. It was amazing, and confusing.
No less confusing was the fact he was still hard, even after his swift orgasm subsided. Still hard and ready to go even, the usual post coital de-sensitivity and pain gone, replaced with only the urge to fuck her more. So, he did, starting up his thrusts again, rolling his hips up and down as he plowed into her fertile crescent, their hips slapping against each other with a loud and audible PLAP-PLAP-PLAP. Alisson moaned in ecstasy, enjoying every moment of it, clutching at him and caressing his back and telling him in his ear what a wonderful STUD he was, a virile STAG, her wanton BULL. He switched to a new breast and immediately started sucking again as he once more came, this time not even pausing to slow down. The rattling of the bed shaking back and forth and slamming against the wall filled the apartment, along with Alisson's passionate and pleasured cries and Greg's utterly insensible grunts and howls.
Somehow, at some point, his mouth popped off Alisson's teat and he wound up on his back. She rode him enthusiastically, bouncing and rolling onto his shaft and coaxing load after hot load out of his dick. Inside her midsection, her core glowed softly, clouds of white gathering around it. Grabbing onto her hips, he slammed himself upward and delivered another load, adding to them. There was only Alisson, and the feel of her body on and around him, and the intense pleasure in his loins as he came repeatedly - whatever hyperactivity that had been imbued to his body letting him deliver over and over. More orgasms than he'd ever had. More than he should have been able to have. Alisson's eyes took the heart shape in their pupils once more and glowed hypnotically, drilling into his brain as she gasped and panted atop him. The last thing he remembered before he finally passed out was one last toe curling cum, his now deflated nuts dry heaving to force out the last few trickles of semen his enhanced body could muster, and Alisson's exultant orgasmic cry cringing in his ears.
He slept deep and well.
