Dimitri, a barely 18 Ukrainian skinny hairless engineer student, has become the secret sexual doll of Sergei, his uncle, a powerful 42 years old mechanics. Sergei has come to spend a few days at Dimitri’s parents' place in Kyiv. Dimitri notices the way his uncle looks at him when he walks around the house in skimpy shorts, and the huge bulge between his thighs. One day, Dimitri finds his uncle’s stinking boxers in the guest room—caked in still-fresh semen—and starts sniffing them. Sergei catches him in the act and forces him to his knees to suck him off. Sergei is tall and very massive, very muscular and veiny with two particularly enormous pecs, biceps, abs, enormous thighs, crazy large shoulders, a bull’s neck, very hairy like a gorilla, even his back, and an extremely hairy groin and balls. He is a real Ukrainian macho. Since that day and until Sergei returns home, Dimitri has to relieve his uncle’s endless sexual appetite whenever Sergei wants it, for hours on end, tirelessly. Sergei loves to destroy his 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 and has so much stamina, he can fuck his nephew until morning without stopping once, creampies after creampies. He is a beast of sex, a pure sexual demon, doing the same with his nephew but also with girls and conquests. Sergei loves having a smelly cock, a stinky groin and turns addicted when he sees Dima’s face choking in that smell. Dimitri’s room stinks of cum and sweat, and the sheets are full of dried semen, a testimony of the sleepless nights where Sergei joins his nephew to destroy him. Dima’s mother often makes comments about the smell and filth of his bed, unaware of the sexual destruction Dima is subjected to. Sergei has a monstrous cock, a pure Ukrainian cock extremely long and unbelievably thick, 26 dark monstrous cm, with two enormous balls that he struggles to fit, and he loves choking Dima with it for hours. He’s become addicted to the sight of Dima in a jockstrap. Sergei is proud of his massive cock, and he is very verbal, dominant, macho. At nights, he turns into a fucker machine, but kind and helpful at day.

Chapter 3: The Midnight Claim

The apartment settled into darkness like a held breath.

Dimitri lay in his bed, the thin sheet pulled to his chin, staring at the ceiling as the hours crawled past. His parents' bedroom door had clicked shut at 11:47. The television downstairs had gone silent at 12:20. The last creak of the old building's bones had faded by 1 AM.

And still he waited.

His body was a live wire stretched taut. Every nerve ending hummed with anticipation, with dread, with that terrible hunger that had taken root somewhere deep in his gut and refused to let go. He could still taste his uncle on his tongue, that salty bitterness that seemed to cling to the back of his throat no matter how many times he'd brushed his teeth.

He'd worn the jockstrap. Of course he had. The thin white cotton was a brand against his skin, the elastic pressed into his hips, the pouch cradling his half-hard cock in a way that felt almost like protection. Almost.

The door opened without a sound.

Dimitri's breath caught. He'd been expecting the creak of hinges, some warning that would let him prepare. But Sergei moved like a ghost, a shadow that detached itself from the darkness of the hallway and slid into the room. The door closed behind him with a click so soft it barely registered.

The nightlight on the desk cast everything in amber gloom. It caught the massive silhouette of Sergei's shoulders, the thick column of his neck, the animal grace of his movement as he crossed the room with slow, deliberate steps.

"You're awake," Sergei said, his voice a low rumble that vibrated through the silence. "Good."

Dimitri's mouth was dry. He opened it to speak, but no words came out. His hands gripped the sheet, knuckles white, watching as Sergei reached for the hem of his shirt.

The fabric lifted, revealing a belly covered in thick, dark hair. It rose in a broad chest, the pecs heavy and defined, the nipples dark and flat against the fur. The shirt came off entirely, and Dimitri's eyes traced the lines of his uncle's body—the impossible breadth of his shoulders, the slab-like muscle of his arms, the coarse hair that covered everything like a pelt.

Sergei's hands went to his shorts. He pushed them down without ceremony, stepped out of them, and stood before Dimitri in the amber glow.

The cock was half-hard and already monstrous. It hung heavy between his thighs, thick as a wrist, dark and veined, emerging from a dense thicket of hair. The balls beneath were huge, drawn up tight against his body, the skin of them loose and wrinkled.

Dimitri couldn't look away.

"You've been staring at this all day, haven't you?" Sergei's voice was amused, dark. "Since I filled your throat this afternoon. Couldn't stop thinking about it."

Dimitri's face burned. He opened his mouth to deny it, but his uncle cut him off with a sharp gesture.

"Don't lie to me. I could smell you from across the dinner table. The way you were squirming in that chair, the way those little shorts barely covered your ass. You wanted this."

Sergei crossed to the bed, the mattress groaning beneath his weight as he climbed on. He moved up behind Dimitri, massive and overpowering, crowding his space until there was nowhere to go, no room to breathe that didn't have Sergei in it.

"On your hands and knees," Sergei commanded. "Now."

Dimitri's body obeyed before his mind caught up. He rolled over, pushed himself up, felt his arms trembling as they took his weight. The jockstrap was a thin barrier between him and the sheets, doing nothing to protect him, only serving to display him.

Sergei let out a low hum of appreciation. His rough hand came down on Dimitri's ass, fingers gripping the flesh, squeezing hard enough to bruise.

"Fuck," Sergei breathed. "Been dreaming about this ass all week. The way it looks in those little shorts. The way it fills out that jockstrap. You've been asking for this since I got here."

"I haven't—" Dimitri started, but the words died in his throat as Sergei's hand reached around, gripping his half-hard cock through the thin cotton.

"Liar." Sergei squeezed, earning a sharp gasp from Dimitri. "Your little dick is already hard. You knew what was coming. You've been waiting all night for me to come in here and fuck you."

Sergei released him and grabbed the waistband of the jockstrap, yanking it down. The fabric slid over Dimitri's hips, his thighs, catching on his knees before Sergei pulled it free and tossed it aside.

"Beautiful," Sergei said, his voice reverent. "You're so fucking beautiful, little doll. Like a piece of art. You know how long I've wanted to take you apart?"

Dimitri's eyes squeezed shut. His body was shaking, every muscle strung tight. Above the shame, above the fear, the wanting raged like a fire in his blood.

"Please," he whispered, not knowing what he was asking for.

Sergei chuckled. "Please what? Please fuck you? Please take you? You're gonna have to find your words, boy."

"I—" Dimitri's voice cracked. A sob caught in his throat, mixed with something that felt dangerously like relief. "Please. I want you to."

"That's right." Sergei's hand landed on his back, palm flat, heavy. "That's my good boy. You want your uncle's cock inside you, don't you? You want to feel it split you open."

Dimitri nodded, his forehead pressed to the mattress. "Yes."

"I couldn't hear that."

"Yes," he said louder, and his voice was raw, broken, desperate. "Yes, I want it. Please, Serge."

The use of the name made his uncle go still for a moment. Then Sergei let out a low growl, and his hand came down on Dimitri's ass with a sharp smack that made him cry out.

"That's my good little whore," Sergei said, his voice thick with approval. "So eager to get fucked. So desperate for your uncle's cock."

He shifted, positioning himself behind Dimitri. The head of his cock pressed against Dimitri's hole, blunt and insistent, and Dimitri felt a spike of pure panic.

He was going to be too big. There was no way it would fit.

"Relax," Sergei said, his voice low and steady. "Relax for me, Dima. You can take it. I know you can."

Dimitri tried to breathe. Tried to unclench, to surrender. He felt the pressure increase, the massive head beginning to push against the tight ring of muscle, and he cried out as it breached him.

The pain was white-hot, blinding. It felt like being torn apart. But beneath the pain, there was something else—something dark and hungry that made his cock thicken and his hips press back into the intrusion.

"Fuck, so tight," Sergei groaned. His hands gripped Dimitri's hips, holding him still. "You're squeezing me like a goddamn vice."

Sergei pushed deeper. Inch by excruciating inch. Dimitri's nails clawed at the sheets, tears streaming down his cheeks. The stretch was unbearable, the feeling of being filled so completely it seemed to reach up into his throat.

"Look at that," Sergei breathed. "Taking all of it. My little doll. My perfect boy."

Finally, with a seat of his hips, Sergei was fully buried inside him. They stayed like that for a long moment, the air thick with the sounds of panting and the smell of sweat and musk. Dimitri could feel every heartbeat of his uncle's cock inside him, the blood pulsing through that massive shaft.

"Fuck, Dima. You feel better than I imagined."

The first thrust was slow, almost tender. Sergei drew back, the thick ridge of his cock dragging against Dimitri's insides, and pushed forward again—deeper, harder. Each stroke was a shockwave that radiated through his body.

"Don't move," Sergei grunted. "Just lie there and take it. Like the good little boy you are."

He began to fuck him in earnest. Slow at first, but each thrust grew harder, hungrier. The bed frame started to creak, a rhythm forming in the dark. Dimitri's moans were muffled by the sheets, breathless and shameful.

"You like that?" Sergei's voice was rough, ragged. "Fucking tell me you like that."

"Yes," Dimitri gasped. "Yes, I like it. Please, Serge, don't stop."

"Never." Sergei's hips picked up speed. "My little boy. I'm going to fuck you every night I'm here. You're going to be my personal little cocksleeve. Every night, Dima. Every night until your head is so full of my cum you can't think about anything else."

The pace grew brutal. Sergei was pounding into him now, his massive body slamming against Dimitri's slender frame with each thrust. The sound of skin on skin filled the room, punctuated by wet, obscene noises.

But the ache, the pain, was slowly giving way to something else. Something Dmitri had never imagined possible. Pleasure. An overwhelming, all-consuming pleasure that rushed through his veins and made his own cock leak and pulse against his thigh.

"God," he sobbed. "Oh, God, Serge."

"Nah." Sergei grabbed a fistful of his hair, yanking his head back. "Not God. Just your uncle. The man who owns this little hole. Say it."

"You own it," Dimitri whimpered. "You own me."

"Fucking right I do."

Sergei drove into him, his rhythm turning savage. It was primal, punishing. Every thrust hit deep, deeper than Dimitri thought possible, and the pleasure was turning him inside out.

"I'm going to cum," Sergei growled. "But not inside you. I want to paint your pretty face. Want to watch you take every drop."

He pulled out abruptly, leaving Dimitri gasping and empty. The sudden loss made him cry out, a sound of protest torn from his throat. But then Sergei's massive hands grabbed him, spinning him onto his back.

Dimitri's head hit the pillow, his body splayed open beneath the bigger man. Sergei knelt over him, his face wild with hunger, his cock thick and dripping with pre-cum. He wrapped his meaty hand around his shaft, stroking slowly.

"Open your mouth," he commanded.

Dimitri obeyed, his jaw sliding open, his tongue out. He looked up at his uncle through tear-stained lashes, helpless and beautiful. His body was a pale map of bruises already forming on his hips.

"Fucking beautiful," Sergei breathed. "You're everything I ever wanted."

He stroked himself faster, jaw clenched, eyes fixed on Dimitri's prone body. "You're going to feel this for days, Dima. I'm going to make sure you can't walk without thinking about me. Every heartbeat of yours is going to be mine."

The first rope of cum landed across Dimitri's chest. Hot, thick, so much of it. The second hit his stomach. The third splashed across his face, covering his lips, his chin, his cheeks. Sergei kept stroking, kept pumping, covering every inch of him in white.

"Swallow," he commanded, and the final spurts landed in Dimitri's open mouth.

Dimitri shut his eyes and drank it down. The taste flooded his senses, sharp and potent, and something in him broke open.

Sergei collapsed beside him, the massive body crushing the air from his lungs for a moment before he shifted his weight. One heavy arm draped over Dimitri's chest, and his balls came to rest on Dimitri's thigh, damp and heavy.

"You're mine," Sergei said, his voice thick with exhaustion and possession. "Don't ever forget that."

Dimitri lay there, covered in his uncle's cum, his body aching, his heart pounding. Beneath the shame, beneath the horror of what he'd become, something sang. Something he couldn't name, couldn't fight, couldn't deny.

"I won't," he whispered.

Sergei's hand found his, large and calloused, squeezing gently. For a long moment, the only sound was the tick of the nightlight and the slow steady rhythm of their breathing.

Then the door creaked open, and a sliver of light spilled into the room.

"Dima?" His mother's voice was soft, concerned. "Dima, are you alright? I thought I heard something."

The air froze.
