Rin lay on the bed, his body trembling with exhaustion, every muscle taut with the aftermath of relentless pleasure. His fingers dug into the sheets, knuckles white, as he fought to steady his breathing. The drug in his veins was a wildfire, burning away his control, his pride—everything that made him him.
Konstantin, that son of a bitch... Rin's thoughts were sharp despite the haze. I knew he was desperate, but I didn't think he'd sink this low. Injecting me with an aphrodisiac... like some cheap whore to be drugged and taken. His jaw clenched. He had underestimated the man's depravity. And now, here he was, at the mercy of another predator.
Kai's presence behind him was suffocating—warm, possessive, smug. Rin could feel the man's cock pressing against him, teasing his entrance, already slick with lube and his own traitorous arousal. His stomach twisted in humiliation. His body was betraying him, responding even as his mind screamed in protest.
"I'll make you cum one more time just from getting your ass fucked."
Kai's voice was a low, mocking purr, the words dripping with amusement. Before Rin could snap back, Kai thrust deep, burying himself to the hilt in one brutal stroke.
"A-Arrgh—!" Rin's back arched, a choked gasp tearing from his throat. His fingers scrambled against the sheets, his vision swimming. It was too much—the stretch, the heat, the way his body clenched around Kai instinctively, hungrily.
Kai tilted his head, watching Rin's trembling form with dark fascination. "Hmm." A hum of satisfaction. Then, without warning, he fisted a hand in Rin's hair and yanked him upright, forcing him onto unsteady feet. Rin staggered, his legs shaking, his ass still impaled on Kai's cock.
"Look at yourself." Kai's breath was hot against his ear as he turned Rin toward the mirror.
Rin's reflection was a wreck—flushed skin, sweat-slicked chest, lips parted in ragged pants. His eyes, usually so sharp and composed, were glazed, pupils blown wide with the drug and the relentless fucking. And behind him, Kai—smirking, victorious, his grip possessive on Rin's hips as he began to move again.
"F-Fuck—! Y-You—!" Rin's voice cracked as Kai pistoned into him, each thrust jolting his body forward. He barely caught himself against the wall, palms slamming against the cool surface. His legs threatened to give out, his toes curling against the floor as he struggled to stay upright.
Kai chuckled, the sound dark and taunting. "That is what I'm doing to you, Rin." He punctuated each word with a snap of his hips, driving deeper, harder. "And you're taking it so well."
Rin gritted his teeth, shame and fury warring inside him. He hated this—hated the way his body arched back into Kai's thrusts, hated the broken moans spilling from his lips. But the aphrodisiac was a cruel puppeteer, pulling his strings, turning every brush of skin into an electric shock of pleasure.
Kai leaned in, lips grazing Rin's ear. "If you want to walk out of here on your own two feet, you'd best start making some cute sounds and working your ass." His hand slid down Rin's stomach, fingers pressing just above his cock, teasing. "Or—" Another sharp thrust, forcing a ragged cry from Rin's throat. "—you can bark like a horny son of a bitch. I get turned on even more when someone arrogantly resists me."
Rin's breath hitched. He wanted to spit in Kai's face, wanted to slam his elbow back into that smirking mouth. But his body was weak, his muscles trembling, his cock aching and neglected. The drug made every thought sluggish, every protest die on his tongue.
Kai's fingers tightened in his hair, pulling his head back. "Choose, Rin."
Rin swallowed hard, his pride screaming. But survival instinct won.
A low, shuddering moan escaped him—soft at first, then louder as Kai rewarded him with a particularly deep thrust. His fingers clawed at the wall, his body moving in time with Kai's, shame burning in his chest even as pleasure coiled tighter in his gut.
Kai's laugh was triumphant. "Good boy."
And then he fucked Rin harder, their skin slapping together, the mirror rattling with each brutal snap of his hips. Rin's reflection was a blur of flushed skin and desperate pleasure, his resistance crumbling with every thrust.
The only sounds in the room were the ragged symphony of their breathing and the brutal, rhythmic slap of skin on skin. Kai moved with a relentless, piston-like efficiency, each thrust a calculated act of possession that drove Rin's body forward, grinding his hips against the cold floor. The initial, deceptive warmth of the fire at his front was a stark contrast to the chill at his back and the deep, aching protest in his muscles.
Rin's world had narrowed to a pinpoint of sensation and endurance. His back was a constellation of pain, a sharp, white-hot ache radiating from his tailbone up his spine with every jarring impact. He had long since given up on finding a comfortable position; comfort was not a part of this transaction. His arms trembled from the strain of holding himself up, his knuckles bone-white where they pressed into the rough-hewn stone.
A particularly deep, angled thrust shattered his concentration, forcing a choked, involuntary sound from his throat—a strained mixture of a gasp and a groan. "Nghh... mhmm... s-stop." The plea was out before he could cage it, weak and breathy, and he despised himself for it instantly.
Above him, Kai's rhythm hitched. A low, dark chuckle vibrated against Rin's sweat-slicked skin. "Stop?" he breathed, his voice a silken, mocking whisper laced with the exertion. "But we're just getting to the best part." The thrusts became harder, more purposeful, a punishment for the plea. Rin could feel the coiled tension building in the body behind him, the controlled rhythm beginning to fray into something raw and urgent.
"I'm close.." Kai muttered, the words not a shared intimacy but a final warning, a declaration of his impending victory.
Rin squeezed his eyes shut, bracing for the end. With a final, brutal thrust that seemed to steal the very air from his lungs, Kai let out a guttural, animalistic grunt—a sound of pure, unvarnished release that was somehow more intimate and violating than anything that had come before. Rin felt the hot, sudden flood deep within him, the ultimate, visceral claim. It was a feeling of profound violation, a sealing of some terrible contract.
The moment Kai withdrew, the support vanished. Rin's arms buckled instantly. His body collapsed to the ground in a boneless heap, a marionette with its strings severed. He lay there, utterly spent, his breath coming in ragged, shuddering gasps that scraped his throat raw. His muscles twitched and jumped with spent adrenaline, little aftershocks of the violation he had just endured. A hot, slick trickle began to seep from his bruised and aching hole, a humiliating physical testament to the act, tracing a path down his inner thigh.
The sounds of the room shifted. The heavy breathing was now only his own. He heard the soft, deliberate tread of Kai's feet on stone, the clink of glass, and the glug of amber liquid being poured.
Then came the voice, cold, clinical, and utterly detached, cutting through the haze of Rin' exhaustion.
"It might be fun to test out if someone can really die from this," Kai mused, as if commenting on the weather. Rin could hear the ice cube crack as he took a sip of whisky. "A little experiment. See how much the noble, serious Rin can truly take before he breaks. But I suppose it's a moot point." A pause, another sip. The glass clicked as it was set down on the mantle. "You'll be meeting your maker tonight regardless, anyway."
When Rin opened his eyes, the ceiling above him spun in slow, nauseating circles. His body felt like lead—limbs drenched in a slick mix of sweat, drying saliva, and the musky, choking scent of Kai's pheromones. The bedsheets stuck to his skin like glue. Everything ached. Muscles twitched involuntarily. His throat was raw.
"He did it again..." Rin thought, his vision swimming. "That son of a bitch didn't stop after the first time... he kept going. Again and again."
He tried to move, but his body refused—numb and sore in ways that went beyond flesh.
"If you locked someone up and used them for seven days straight... that's a full goddamn week. People could die from less. I should be dead. I should be dead. Why the hell am I still breathing?"
The remnants of whatever drugs Kai had pumped into him were gone now. He could feel everything. Every bruise. Every tear. Every bit of damage that had been numbed into silence was now screaming through his nerves like a chorus of fire ants crawling beneath his skin.
His gaze dragged across the room—Kai was standing at the far wall, bare-chested and casual, as if he hadn't just spent a week methodically dismantling someone else's sanity. He crouched beside a reinforced safe, calmly keying in a code Rin didn't recognize. The metal door clicked open with a soft hiss, and Kai retrieved something small—something that glinted in the light.
A thin vial.
A syringe.
Rin's pulse spiked.
Kai turned to him, eyes dark but smiling—calm, calculated, chilling.
"You know what this is, don't you?" Kai asked, tone almost sweet. He tapped the vial gently with one finger, holding it up like it was a gift instead of a threat. "This is Tantalex-93."
Rin's blood turned to ice.
"Tantalex-93..." The name struck his memory like a freight train. "That's not a drug. That's a fucking death sentence."
His eyes widened, pupils trembling.
"That thing—when it goes through radioactive decay, it releases thousands of times more alpha particles than radium. Alpha radiation doesn't travel far, but inside the body? It's catastrophic. Ridiculously toxic. Even the tiniest trace of it in the bloodstream would destroy your cells from the inside out. Nerve tissue, organs... liquefied. There is no 'low dose'—just fatal, or instantly fatal."
Kai approached the bed with the syringe in hand, walking like he had all the time in the world. His bare feet were soundless on the polished hardwood, like a predator on the prowl. His expression wasn't angry. It wasn't even cold.
It was worse.
He looked pleased.
He crouched beside Rin, tucking one leg under him like this was just some late-night conversation between friends. Then, with the gentlest touch—one that made Rin's skin crawl—he brushed aside a sweat-soaked lock of Rin's hair. His fingers were warm. The gesture almost felt... tender.
"Awwn, you're so cute like this..." Kai murmured with a smirk, eyes twinkling with fake affection. His gaze drifted downward, landing on Rin's trembling fingers—pale, slick with sweat, twitching in pain. Kai reached out and lightly traced the tip of his thumb along Rin's knuckles. He pressed down, hard enough for Rin to feel the threat in the softness.
"Would you like me to start by chopping off your fingers?" he asked sweetly. "They're cute. I'd keep them in a jar."
Rin didn't flinch—but only because his body had already passed the point of reacting.
"He's enjoying this. Every second. Not just hurting me, but watching me fall apart in real time."
Kai's cruelty wasn't born of rage—it was practiced, layered. There was technique to it. "He's peeling me back like skin off fruit."
Then Kai chuckled to himself and tilted his head, as if remembering something.
"'Body found in Lake Onega.'" he said suddenly, as if reciting a headline, then snorted. "Not a bad way to go. Sounds tragic. Mysterious. Even poetic."
Rin stared at him, silent, every nerve in his body screaming.
"I'll even let your comrade retrieve your naturally frozen corpse," Kai added, smiling like he was doing him a favor. "Though I bet he's still pissed at you—y'know, after you beat the shit out of him."
Rin's heart lurched.
"My comrade? Who the hell—?"
His mind scrambled through memories, injuries, missions. "...Wait. Could it be—"
A face flickered in his head.
"No. No way. He's alive?"
Kai's smile widened as if he could hear the thought forming. "By the way, seems like your own people hate you too. So much drama."
He reached into the vial and slowly drew the shimmering drug into the syringe. The liquid moved unnaturally—thicker than water, but lighter than oil. It caught the light in a metallic shimmer like it was alive.
"But really," Kai said, tilting the syringe and flicking it lightly, "how does a intelligence agency send the wrong photo by mistake? That kind of thing doesn't just happen, Rin. Not unless someone wants you dead."
Rin's breath hitched.
"No... That mission. The briefing. That wasn't an error? They sent me out there knowing—"
The pieces weren't just falling into place—they were crashing.
"Was I the target?"
"Oh—and did you ever find out about your superior's dirty little secret?" Kai added with a teasing lilt.
He glanced down at Rin's stunned expression.
"Judging by your face... guess not," he said, snorting. "Yikes."
Rin's chest was tightening fast, panic rising like pressure in a sealed chamber.
Too much. Too fast.
"So much information—he's flooding me on purpose. I can't process it all. It's chaos by design. He's burying me in it."
His heart pounded like a warning siren.
"Why did PSIA give me the wrong intel? Was I set up? What happened to my comrade? What 'secret'? What—what the hell is he injecting me with?!"
Then he saw Kai bring the syringe to his neck.
"No. No—NO."
"I can't die like this. Not now. Not while I still don't understand. Not before I—"
With a sudden jolt of raw survival instinct, Rin summoned everything left inside him. He lunged—not gracefully, not heroically—just violently. Arms trembling, he shoved Kai with what strength he had.
But Kai didn't budge.
The man barely rocked back before pinning Rin's shoulder to the mattress with one hand. He didn't even look annoyed—he was amused.
"Aww," he said softly. "Still fighting."
He leaned in, his voice almost affectionate.
"That's cute."
Then, without hesitation, Kai drove the needle into the side of Rin's neck.
Rin screamed. Not from pain—it was ice crawling through his veins.
"This is it. This is how I die."
He could feel the poison burning its way into his bloodstream, corroding his thoughts, turning fire into fog. His vision blurred like a camera losing focus, light streaking across his eyes in distorted halos.
The world was melting.
All he could hear was:
Click.
Click.
And then Kai's low chuckle, close to his ear. The sound was gentle, even fond.
"Твоя глупая котенок," he whispered, grinning. ["You stupid kitten."]
And then—darkness.
