Chapter 4: The Field Test Begins
The transformation had settled into his bones. Jin lay panting, his new body a foreign landscape strapped to the bed. The youthful face he’d known in the mirror—the 19-year-old prince with a clean jaw and earnest blue eyes—was now a cruel joke. It floated above a physique that belonged to a veteran gladiator, a seasoned manwhore who’d spent years sculpting himself for war and pleasure.
His shoulders were broad, cantilevered slabs of muscle that strained against the manacles. His chest was a pronounced, beefy plate, swollen and defined with thick pectorals that pushed forward with a new, arrogant weight. They were sensitive, the skin stretched taut, and centered on each were his new nipples—larger, a vivid, embarrassed pink, and standing perpetually pert and pebbled against the cool air. His arms were corded with new veins, his biceps fuller, his abdomen a razor-sharp eight-pack that looked carved from stone. He looked like a man in his prime, a dominant alpha in his late twenties, with the betrayed, young face of a boy trapped atop it all.
Sori watched him take inventory, a slow smile spreading across her face. “Better,” she purred. “Much better.”
She shifted her weight, rising from his thighs. Jin watched, helpless, as she positioned herself above him, her knees on either side of his hips. Her small hand wrapped around his new, enhanced cock. It was a shocking sight—the sheer size of him in her grip, the bright pink glans glistening, an obscene flagpole of his violation. She guided him, the swollen head pressing against her entrance.
Then she sank down.
Jin’s back arched, a silent scream caught in his throat. The sensation was beyond anything. It wasn’t just entry; it was a hot, velvet fist closing around him, a perfect, searing fit that massaged every pulsing inch. Her inner muscles clenched in a slow, rippling wave, squeezing him from root to tip in a way that made his new, heavy balls tighten instantly.
“Oh gods,” he choked out.
She began to move. Not just move, but ride him with a practiced, devastating rhythm. She bounced, each descent a deep, impaling conquest, each rise a tantalizing withdrawal that made his oversized cock weep. Her inner walls were a living entity, clutching and milking him, stroking him with an internal friction that mapped every throbbing vein.
Leaning forward, she let her silver hair trail over his swollen chest. Her mouth found one of his enlarged pink nipples. She licked, a flat, wet stripe over the hypersensitive peak, and he jolted against his chains. Then she sucked, drawing the entire pebbled areola into the heat of her mouth, nipping gently with her teeth.
A wildfire of sensation erupted from that point, racing straight to his groin. He cried out, a ragged, broken sound. His new body was a network of exposed wires, and she was playing every one.
Every bounce was a revelation. Her incredible inside worshipped his XL genital with relentless, addictive precision. It squeezed him in pulsing rings, massaging the sensitive underside of his glans, then gripping the thick shaft with a velveteen vice as she plunged down. It was a continuous, milking pull, as if her very body was designed to siphon the essence from his newly enhanced, achingly full stones. He felt each internal fold, each textured contour that seemed to cling to him, coaxing him toward an inevitable explosion.
In that moment, as pleasure detonated along his spine, the truth crashed into him with more force than the ecstasy. He had fucked up. He had screwed up royally. This wasn’t a battle lost; it was a total surrender of his old self. The proud prince was gone, replaced by this hulking, responsive vessel of need, chained and being expertly ridden into oblivion.
The climax didn’t build. It simply erupted.
A raw, deafening scream tore from his lungs, a howl of absolute dominance and defeat mixed into one. His hips slammed upward, driving himself as deep into her as the chains would allow. From his bright pink glans, the ejaculation was not a release but a geyser.
It gushed into her in extreme, relentless shots, a voluminous flood that felt endless. He could feel it, a hot, pumping torrent filling her, drenching her inner walls. The sensation was so profound, so visceral, he could almost hear it—a thick, internal splattering that quickly overflowed. He pumped and pumped, a seemingly impossible volume spilling out from where their bodies joined, pooling hot and slick on the bed beneath them.
His mouth hung open, eyes wide with shock. Is this sex? The thought was a distant echo. Ejaculating this much? It felt like a cupful, 250ml or more, a full reservoir emptied with violent force. The euphoria was a blinding white noise, a primal roar in his skull. It wasn’t just pleasure; it was a biological imperative fulfilled on a monstrous scale. The sensation screamed that he was made to breed, to mate a lot, to pump gallons of seed deep—a dark, instinctual programming that now felt as fundamental as breathing.
Sori moaned, a long, satisfied sigh as she ground against him, milking the last spurts from his twitching length. Across the room, Ueno stirred from his rug. The little land shark blinked sleepily, yawned to show a brief glimpse of needle-sharp teeth, and began meticulously licking a paw. He glanced at the tangled, sweating pair on the bed, let out a soft, snuffling noise that sounded almost like a shrug, and curled back up, turning his back to them.
Spent, Jin collapsed. His new, well-used body was a map of sweat and tension. Sori, with a final, slow roll of her hips, slid off him and rested against his side, her head on his beefy, heaving chest. She traced a finger through the mess cooling on his abdomen.
After a moment, Ueno padded over, hopped onto the massive bed, and nestled his sleek form against Jin’s other side, letting out a contented purr.
Jin stared at the cavernous ceiling, the sigils pulsing softly. He wasn’t sure how to feel anymore. There was no anger, no pride, no plan. There was only a deep, hollowing exhaustion and the ghost of that terrifying, all-consuming euphoria thrumming in his veins. His eyes, heavy, began to close. The last thing he saw was Sori’s smile, before the darkness of a dreamless sleep pulled him under.
