Lena slammed her hips down on Jake's cock, taking every thick inch into her tight cunt in one greedy drop. "Fuck me harder, you bastard," she growled, sweat already slicking her skin. Jake gripped her ass and pounded up into her, balls slapping wet against her. But something was shifting inside her. Heat bloomed low in her belly, spreading fast. Her flat stomach began to push outward, skin stretching smooth and tight.
"What the fuck is happening?" she gasped, but she didn't stop riding him. Her belly swelled bigger with every thrust, rounding into a heavy, fertile curve. Jake stared, eyes wide, but his cock got even harder inside her. "Jesus, you're turning pregnant right on my dick," he snarled. He slammed up deeper, watching her new belly jiggle with each brutal thrust.
Her tits swelled next, growing heavy and full, nipples darkening and thickening into fat, sensitive buds. Milk beaded at the tips almost instantly. Lena moaned like a whore as the weight hit her, her back arching to thrust those massive pregnant tits forward. "Suck them," she demanded. Jake latched on, sucking hard, and warm milk flooded his mouth. She came instantly, pussy clenching and squirting around his cock while her belly kept growing, now a full, round pregnant dome resting on his abs.
The transformation didn't stop. Her hips widened, ass fattening into thick, fuckable cheeks. Her thighs grew plush and strong. Every inch of her turned hotter, sexier, built for breeding and fucking.
Her pussy lips puffed up, slicker and hotter, gripping Jake's cock like it was starving for cum. "Look at this pregnant slut body," Jake grunted, slapping her swollen belly. The sound was loud and filthy. "You were flat an hour ago. Now you're a dripping, knocked-up fucktoy."
Lena couldn't stop moving. She leaned forward, belly pressing against him, and rode harder, milk spraying from her nipples with every bounce. "Fill this pregnant cunt," she begged, voice raw. "Make it bigger. Knock me up even more." Jake flipped her onto her back, spread her thick legs wide, and drove back in. Her new pregnant belly sat high and tight between them, perfect for grabbing. He fucked her like an animal, balls-deep strokes that made her swollen tits and belly shake.
She came again, screaming, pussy milking him. But the change kept going. Her belly grew rounder, tighter, skin shiny and stretched. The baby bump looked full-term now, heavy and erotic. Her clit swelled bigger, poking out, begging for attention. Jake thumbed it while he fucked her, and she squirted again, soaking his balls and the sheets. "This is the hottest fucking thing I've ever seen," he said, voice thick with lust. "My girl turning into a sexy pregnant breeding slut mid-fuck."
He pulled out, flipped her onto all fours, and slammed back in from behind. Her massive belly hung low, swinging with every thrust. Milk dripped from her hanging tits onto the bed. Jake reached around, grabbed her swollen belly with both hands, and used it like a handle to yank her back onto his cock. "Take it, pregnant whore," he growled. "This body was made for cock now." Lena pushed back, meeting every thrust, her new curves jiggling obscenely.
She came a third time, then a fourth, each orgasm stronger because of the changes. Her pussy felt more sensitive, tighter around his shaft despite how stretched she was. Jake's pace turned frantic. "Gonna cum in this pregnant cunt," he warned. Lena begged for it, voice hoarse. "Breed me more. Fill my swollen belly with your load." He buried himself to the hilt and exploded, pumping rope after rope of thick cum deep inside her. Her belly seemed to swell even more with the heat of it, round and perfect.
They collapsed, but only for minutes. Jake's cock stayed hard inside her. The transformation had made her insatiable too. She rolled onto her side, lifted one thick leg, and he slid right back in, fucking her slow and deep while he rubbed her massive pregnant belly. Milk leaked steadily now. He licked it off her nipples, biting gently, and she came again with a long, broken moan.
By the time the sun rose, Lena was fully transformed: a hot, sexy, heavily pregnant woman with a round, fertile belly, huge milky tits, wide breeding hips, and a dripping, greedy cunt that couldn't get enough cock. Jake fucked her in every position, on every surface, filling her over and over. She rode him reverse, belly and tits bouncing wildly. She lay on her back with her legs spread obscenely wide while he pounded her. She sucked his cock between rounds, tasting their mixed cum, her swollen belly resting on the floor.
Every orgasm made her feel more complete, more sexual, more owned by this new body. Jake kept talking dirty the whole time, calling her his pregnant fuckslut, his breeding goddess, his hot and sexy transformed girl. She loved every filthy word. By morning she was leaking milk and cum, belly huge and tight, pussy swollen and used, and already hungry for the next round.
She looked down at her transformed body and smiled, already planning how to make it happen again.
