Dimitri, a barely 18 Ukrainian massive bulky and hairy student, has become the sperm receptacle of Sergei, his uncle, a powerful 50 years old man, since so many years now. Sergei never had a wife, but he is a beast of sexual needs, having difficulties to find women to relieve himself until he finally gave in and try with his nephew. Sergei works in a factory and still lives in his brother’s house, Dimitri’s father, and his wife (Dimitri’s mother). Sergei is tall and very massive, bulky but very muscular and veiny with two particularly enormous pecs, very hairy like a bear, even his back, and an extremely hairy groin and balls. Je is a real Ukrainian gorilla. Dimitri has to relieve his uncle’s endless sexual appetite since ever, he only knows this cock and this body, and he is now completely addicted to it. Sergei loves to destroy his massive nephew all night long, split him open without sleeping until morning, discreetly so his parents won’t hear anything, Dima swallowing gallons of cum and torrents of precum. Sergei is a real fucker, needs no rest even he works hard and can fuck his nephew until morning without stopping once, creampies after creampies. Even at his age, he has so much stamina, and he is a beast of sex. Sergei loves having a smelly cock, a stinky groin and turns addicted when he sees Dima’s face choking in that smell. His room stinks of cum and sweat, and the sheets are full of dried semen, a testimony of the sleepless nights where Dima is destroyed by his uncle. Sergei has a monstrous cock, a real Ukrainian cock extremely long and thick, 26 monstrous cm, with two enormous balls and he loves choking Dima with it for hours in the deep nights. Sergei is proud of his massive cock, always talking about the size of it, and he is very verbal. At nights, he turns into a fucker machine, a beast of sex, very dominant like Dima never sees.

Chapter 2: The Midnight Beast

The door clicked shut, a sound softer than a heartbeat but one that jolted through Dimitri’s spine. He didn’t turn over. He lay on his stomach, the worn cotton of his pillowcase rough against his cheek, listening to the heavy, familiar footfalls. The musky, animal scent arrived first—old sweat, the pungent grease from the factory, the deep, sour smell of Sergei’s groin that had seeped into the very walls.

A massive hand, calloused and warm, landed on the back of Dimitri’s neck, not caressing, but claiming. The weight of the man settled on the edge of the bed, the frame shrieking in protest.

“You smell like a boy who’s been waiting,” Sergei’s voice was a low rumble, stripped of its daytime casualness. It was all gravel and hunger now. His other hand slid under the hem of Dimitri’s t-shirt, fingernails scraping through the dense hair on his flank. “You are a good boy, Dima. A good, empty boy.”

Dimitri trembled. Shame was a cold stone in his gut, but beneath it, a liquid heat was already spreading, treacherous and eager. He pushed his face deeper into the pillow as Sergei peeled the shirt up and off him. The cool air of the room hit his back, then was immediately displaced by the overwhelming furnace heat of his uncle’s naked chest pressing down.

Sergei’s body was a cage of hair and muscle. He covered Dimitri completely, his beard scratching the boy’s shoulder, his breath hot and beer-tinged against his ear. Dimitri could feel the monstrous, thickening length of Sergei’s cock already prodding against the cleft of his ass, slick with its own leaking pre-cum.

“No sound from your smart mouth tonight, eh? Just your hungry hole.” Sergei’s hand left his neck and fumbled between their bodies. Dimitri heard the wet, filthy sound of Sergei spitting into his own palm, then the slick, rough strokes as he lubed his cock. It wasn’t for comfort; it was ritual. The spit mixed with the copious pre-cum, making a sticky glue.

Then, the blunt, unyielding pressure.

Dimitri gasped, his fingers clawing at the sheets. There was no gentle easing, no question. Sergei used his full weight, hips driving forward in one brutal, splitting shove.

“Fuck!” Dimitri hissed, the air punched from his lungs. The burn was catastrophic, a white-hot tear that consumed him. He was stuffed, impaled, stretched obscenely wide around a thickness that felt like it would unmake his spine.

Sergei groaned, a deep, satisfied sound from the very core of his being. He buried himself to the hilt, his heavy balls slapping against Dimitri’s taint. “There. That is home. You feel that, my bull? Your guts know this cock better than your own name.”

He began to move. Withdrawing almost completely, the drag a sharp agony of friction, then slamming back in with piston-like force. Each thrust was a localized earthquake, jolting Dimitri’s body up the bed. The headboard slammed against the wall with a dull, rhythmic thump-thump-thump. Sergei’s pace was relentless, machine-like, his hips a blur of powerful motion.

“You take it… you take your uncle’s fucking dick like you were built for it,” Sergei grunted, his words punctuated by drives. Sweat dripped from his beard onto Dimitri’s back. “Think your father hears? Thinks his big son is just having a dream?”

Dimitri couldn’t answer. He was a vessel of sensation—pain, fullness, a degrading pleasure that coiled tight in his balls. He was hard, his own cock trapped and leaking beneath him. He moaned into the pillow, the sound muffled, desperate.

Sergei shifted, hooking a massive arm under Dimitri’s chest and hauling him up onto his knees, arching his back. The new angle was deeper, more vicious. Sergei’s free hand wrapped in Dimitri’s hair, yanking his head back. “You see? Look at yourself. A bear cub, split open on my pole.”

In the fractured, dusty mirror across the room, Dimitri saw a grotesque reflection: his own flushed, tear-streaked face, his body bowed and dominated by the hairy beast behind him, the brutal, mesmerizing slide of that veined monster in and out of his ravaged hole.

“I’m gonna fill you,” Sergei promised, his voice dropping to a guttural whisper. “Gonna pump my seed so deep into your belly it’ll never come out. Make a pregnant boy out of you. Would you like that? A big, pregnant nephew for your uncle?” His words were filthy, insane, and they sent a new jolt of electric submission through Dimitri.

The pace became frenzied. Sergei’s balls tightened, slapping harder. His breath came in ragged, animal huffs. “Here it comes. Take your milk, you fucking slut. Take it all.”

With a roar that was mostly a stifled groan, Sergei slammed home and held. Dimitri felt the first violent, hot pulse deep inside him, a torrent of thick cum flooding his channel. Sergei ground his hips, milking every spurt, each jet a claim. Dimitri came untouched, his own orgasm ripped from him by the feeling of being injected, owned, used.

Sergei stayed buried, softening slowly, his weight a crushing comfort. He licked a stripe up the salty column of Dimitri’s neck.

But it was not over. It was never over.

After five minutes of heavy silence, Sergei pulled out with a wet, sucking pop. A hot gush of cum followed, soaking Dimitri’s thighs and the sheets below. Sergei chuckled, slapping Dimitri’s asscheek, making the boy jump.

“Just cleaning the pipe,” Sergei murmured, rolling onto his back. He was already hardening again, his cock a dark, wicked shape against his hairy belly. “The night is long, Dima. We have only just started.”

And as the faint, grey light of pre-dawn began to bleed at the edges of the blinds, Sergei took him again. And again. A different position each time—on his side, lifted against the wall, on his back with his legs over Sergei’s shoulders. Each round was a fresh destruction, each creampie a renewed violation, a hot, liquid seal. The room’s stench grew richer, more layered: fresh sex, fresh sweat, the unmistakable tang of spent seed.

Sergei was a machine, a gorilla of need. He talked throughout, stories of women in the factory, of his own youth, filthy praises of Dimitri’s addicted body. His stamina was supernatural. Dimitri lost count after the fifth, his body reduced to a shuddering, overfilled receptacle, sore and used and somehow, horribly, still craving the next filling.

The last time, as the first true birdsong sounded outside, Sergei finished with a shuddering groan, emptying a final, seemingly endless load. He collapsed beside Dimitri, his heart hammering against the boy’s side.

In the silence, he traced a finger through the mess on Dimitri’s stomach. “You are my best work,” he said, his voice now tired, almost tender with possession. Then he rose, the bed groaning in relief. He pulled on his pants, leaving Dimitri broken and leaking on the ruined sheets.

At the door, he looked back, a massive silhouette against the grey light. “Sleep. I will see you at breakfast.”

The door closed. Dimitri lay in the devastating aftermath, the evidence of the night cooling on his skin and inside him. The shame crashed down, a tidal wave. But beneath it, a hollow, aching need yawned wide, already waiting for the next midnight visit.
