Chapter Text
“Shuichi, c’mon, it’ll just be a half hour! I need a break, be a bro, please?” Kaito slapped his hands together in what was almost a prayer, begging Shuichi, who kept one eyebrow raised.
“A half hour which is illegal,” Shuichi argued, eyeing the door to the criminal they were supposed to be watching. “We have to take our shift over. And I know you, a ‘half hour’ is easily 120 minutes before you realize it. Not my fault you can’t remember your girlfriend’s birthday.”
“Shuichiiii,” Kaito groaned. “I haven’t told anyone about your porn collec-”
Shuichi loudly coughed, turning to stare at the guard standing duty at the end of the hallway. “That isn’t against the law, Kaito,” Shuichi forced out, a heavy blush coating his cheeks. “But fine, whatever. Get her something nice, and I better not catch you buying her a car starter or something stupid like that.”
Shuichi’s coworker lit up, hitting his shoulder a little too hard for Shuichi’s liking. “You’re the best man! I owe you one!”
Shuichi shook his head as the purple haired man took off the hall. “Yeah, yeah,” Shuichi sighed to himself, rolling his eyes and turning to swipe his card through the card reader. With a beep, he stepped into the ever cold prison room, giving a nod to Kaede and Rantaro.
“Hey guys,” Shuichi smiled, nodding at Rantaro as he passed off a clipboard of information to Shuichi. “How was the shift?”
“Pretty good!” Kaede nodded with an ever cheery smile. “He didn’t try much, just some lies and whatnot.”
“This is your first time with this prisoner, right Shuichi?” Rantaro asked, resting a hand on his shoulder reassuringly. “You reviewed the files ahead of time, I assume?”
“Kokichi Ouma,” Shuichi supplied, brain flashing back to his first job watching a serious criminal. “Serial killer, 23 known victims.”
Kaede nodded. “You’ll do great Shuichi, I know it! Where’s Kaito? Wasn’t he supposed to be on shift with you?”
Shuichi screwed his eyebrows together. “He had to use the restroom.”
“Well, we’ll leave the rest to you,” Rantaro lazily saluted, the duo leaving and taking their much deserved break.
Shuichi closed the door, resting his head against the cold metal and taking a stabilizing breath. Kaito better be fucking grateful.
“Wow, you about to have a panic attack just from spending time with lil ol me? Am I that scary~?”
Shuichi tensed, whipping around to the criminal smirking at him, handcuffed to the table and his ankles to the chair legs. Shuichi felt heat rising to his cheeks as he realized that oh fuck, this guy was HANDSOME. Soft skin, pink lips, amethyst eyes that bore right through Shuichi’s soul, purple tipped hair that defied gravity. Shuichi found himself having to tear his eyes away on the reminder of just how many people this guy had killed, clearing his throat and washing away all his inappropriate thoughts.
“I’m not scared of you,” Shuichi answered, doing his best to channel an aura of superiority. “And I’m not here for small talk either, I’m a prison guard not some life guidance counselor.”
“There’s an attitude on this one, eh?” Kokichi teased, leaning back as much as he could in the unforgiving metal of his seat. “What’s your name, cutie?”
A soft pink flush came to Shuichi’s cheeks, plopping down on a stool and devoutly not looking at the way too handsome prisoner he had on his hands. “That’s not something you need to know.”
“Awh, c’mon, it’s not like I can do anything, locked up like this!” Kokichi chortled. “You know my name, it’s only fair!”
“...”
“The silent treatment? Officer, I haven’t been that bad of a boy~”
“Don’t say things like that!” Shuichi yelped, blush coming back at full force. “It sounds sexual!”
Kokichi snickered, wide grin adorning his face. “Tell me your name and I’ll stop!”
“I still don’t want to tell you my name.”
“Oh, so you’re a pervert then, daddy?”
“Oh my fucking god, never say that again.” Shuichi covered his face with a hand, rubbing the bridge of his nose. “My name’s Shuichi Saihara… just don’t tell anyone I told you.”
Kokichi perked up. “Ooo, fancy! Nice to meet ya, Shumai!”
“I’d say the same, but I don’t find meeting murderers quite enjoyable,” Shuichi snorted, wishing Kaito could come back already. He fiddled with his uniform, staring at the edge of thread poking out of the seam and pulling at it, devoutly refusing to meet Kokichi’s eyes. In fact, he tugged his cap down lower, feeling Kokichi’s gaze on him.
“Ehhh? You didn’t become a security guard because you find serial killers crazy hot? What a rip off…”
Shuichi huffed, shaking his head. “What exactly do you think officers do…? I became a prison guard to keep horrible criminals like you locked up.”
“What if they really, really deserved it though?” Kokichi whined.
“I can quite assure you, no matter what anyone does, they don’t deserve to be choked till they passed out, then wake up hung upside down like maggots slowly grow inside their open wounds,” Shuichi retorted, reminding himself of just how horrible Kokichi was. “No one should suffer that fate.”
“Aww, but all roads lead to death in the end! What’s so bad with speeding up the process? I myself am on death row, ain’t that the same thing?”
Shuichi considered it, resting his head on the wall behind him. “I guess,” Shuichi managed. “But the authorities just do it so there’s no chance of horrible people escaping and killing other people. Plus, it’s clean and quick.”
“Please,” Kokichi scoffed. “It’s torture, but people ignore it because it’s under the shiny band of ‘justice’. What even is justice? Why is it that everyone just ignores the fact people are being killed just because the people dying are criminals, when they’re about to do the same thing to me that I’ve done to others?”
“...I didn’t come here to debate the morality of death row.”
“Boring! It’s on my mind, can’t Shumai be nice and at least entertain me before my death?”
“You talk about it so casually, it’s like it doesn’t.. affect… you..” Shuichi moved his head, trailing off as he stared wide eyed at the sight before him. Or more like, just a little too close to him.
Kokichi sat, crouched in front of him, resting his elbow on his knee and cheek on his palm, sexy mischievous glint in his eyes. Shuichi gulped, eyes flicking to where all the handcuffs lay abandoned. As Shuichi’s brain caught up with what was going on in front of him, his heartbeat thundered, alarm bells ringing way too loud way too late.
“You know, Shumai,” Kokichi purred, slipping a hand forwards and dragging one enticing pointer finger up Shuichi’s inner thigh, prisoner staring up at the officer with an almost hungry glint in his eyes. “You’re the exact kind of man I’d love to see bloody, dying as you gasped for air by my hand~ I wonder what you’d be like in your final moments, nishishi~”
Shuichi jumped back as best he could against the wall behind him, grabbing his gun and shakily aiming it right at Kokichi’s forehead. “Back up, I’m n-not afraid to fire!”
Kokichi laughed under his breath, eyes landing on Shuichi’s slightly erect cock. “Sure you’re not, Shumai, sure you’re not. C’mon, do it then. It’d be faster than whatever they have planned for me. Here, I’ll even help you!” Kokichi leaned forwards, allowing his forehead to press even against the machinery. “Shoot! Shoot me, I dare you, shoot me and know you’re just as bad as I am, a killer just like me.”
Shuichi’s breath came out in hurried pants, clammy sweat pouring down his face while Kokichi smirked up at him. He screwed his eyes shut, pointer closing around the trigger and-
A silent anticipation filled the room before Shuichi dropped the gun, staring down at Kokichi with watery eyes. Kokichi crooned softly, standing and situating himself on Shuichi’s lap. “There there, Shumai,” he giggled, petting his guard's hair in a demeaning fashion. “It’s not bad to have a moral code! Mr. Ouma will save you from all your fears~”
“Fuck off, just because I don’t want to kill you doesn’t mean I can’t-”
“Restrain me?” Kokichi purred, holding up Shuichi’s handcuffs. “Yeah, sure you can. Oh, you can’t expect help either, I have one of my minions working in the security room.”
“So you could’ve just escaped at any time?” Shuichi asked, hands shaky as a bead of sweat slipped down his cheek.
Kokichi shrugged, grinning. “Yeah, basically.”
Shuichi flinched as Kokichi’s hands slowly groped his body, slow and light enough that Shuichi could easily push him away. Feather light touches skimmed around Shuichi’s nipples, the criminal making a pleased sound as they stiffened. A blush coated Shuichi’s cheeks as warmth rushed to his dick, mortification filling him as he realized he could easily stop Kokichi, but he didn’t want to, not remotely.
“You’re an asshole,” Shuichi breathed out, peeking at Kokichi with wide eyes around the brim of his cap. “You know that?”
“Hm~! I hadn’t ever considered that, just because you called me that I’m reconsidering all my previous actions and have become a better person!” Kokichi teased, wrapping his palm around Shuichi’s clothed erection and grinding the ball of his hand against his tip. Shuichi groaned at the friction, hand darting to cover his mouth while he subconsciously bucked his hips forwards. “Aww, why cover your filthy sounds Shumai? Embarrassed to be turned on by a killer like me? It’s okay to have a murder kink y’know~”
“Shut up,” Shuichi huffed, yelping as Kokichi squeezed him punishingly hard, pain radiating through him, followed by masochistic pleasure. “That hurts-!”
“You listen to me, bitch,” Kokichi growled. “Don’t back talk me. You’re forgetting who’s in charge here.”
Feeling snarky, Shuichi raised a brow down at him. “Which is, legally, me- oh fuck!”
Kokichi lowered his mouth, biting down hard on Shuichi’s clothed dick. The officer could feel Kokichi’s teeth digging into his flesh, overwhelmingly painful. “Ah~ stop, stop, I’m sorry-!”
Kokichi pulled back with a giggle, instead licking the now completely erect cock a couple times through the fabric. “Good boy, Shumai, I knew you had it in you~ you know just how to be a perfect slut for me, don’t you?”
Wordlessly, Shuichi nodded, thrusting his hips against Kokichi’s face while he quietly cackled. “You’re quite the sadist, aren’t you?” Shuichi forced out, tears pooling at the edges of his eyes from the earlier torture.
Kokichi rolled his eyes, pulling back from Shuichi’s dick and beginning to unbuckle the officer’s belt. “Oh my god, you’d never guess, the serial killer who loves torturing his victims into suicide is a sadist!! Who would’ve thought?!”
Shuichi swallowed back a snappy remark, lifting his ass so Kokichi could pull off his pants and boxers easier. His cock sprung out of the fabric, precum drizzling out of the tip while goosebumps cascaded down his thighs from the cold prison air. Kokichi hummed, rubbing a thumb over where his teeth pierced Shuichi’s skin with an appreciative expression.
“Kichi,” Shuichi whispered with a slight moan. “P-please.”
“Please what?” Kokichi asked, pulling his fingers back from Shuichi’s length to rub against the top of his thigh.
“Please touch me,” Shuichi whined.
“Oh? But I’m touching you right now, am I not?” Kokichi tilted his head in a way that was all too cute, and Shuichi could swear his heart skipped a beat. “Or did you want me to touch you somewhere else? Use your words my beloved.”
Shuichi whimpered, glancing away from Kokichi with a heavy flush. “If so,” Shuichi whispered. “Could you please touch my dick?”
The officer moaned as Kokichi immediately grabbed his shaft, pumping him far too quickly while Shuichi squirmed, fighting against the overwhelming pleasure. “A-ahh~”
“You like that, useless whore?” Kokichi purred, wide grin on his face as Shuichi rutted his hips into Kokichi’s hand. “C’mon, answer the question, or I’ll have to punish you again~”
“Ngh- Y-yes I do, I’m a useless slut~!” Shuichi cried, digging his hands into Kokichi’s hair. “P-please, don’t stopp~!”
“Nishishi~ what a good boy, admitting he’s not good for anything but sex~!” Kokichi chuckled, pulling his hand away from Shuichi’s twitching member. At Shuichi’s whine, Kokichi responded, “Don’t worry, I’ll be making you feel even better soon.”
“What do you mean- mmph-!” Shuichi gasped as Kokichi lapped his tongue against the rim of Shuichi’s ass, smirk adorning the convict’s face as Shuichi clenched his thighs around Kokichi’s head. His fleshy muscle slipped inside of Shuichi’s hole, teasingly diving his tongue in and out while Shuichi moaned, always clenching a second too late to squeeze around Kokichi. While Kokichi teased Shuichi, he began to squeeze the muscle of Shuichi’s thighs, massaging them so hard Shuichi wondered if it’d bruise. Of course, he barely had any time to think about that before Kokichi pressed his tongue all the way inside of Shuichi, who let out a debauched porn star moan at the intrusion. Kokichi snickered, vibrating Shuichi’s ass in a way that was far too pleasurable for Shuichi’s own good. The sounds of Shuichi’s whimpers cascaded through the room as Kokichi curled his tongue, working Shuichi’s tight ass open. The feeling of the spit covered muscle squirming inside of him left Shuichi panting for breath, warmth pulsating through his gut. Shuichi leaned forwards, curling in on himself and letting out a scream of enjoyment as the motion pressed the tip of Kokichi’s tongue against his prostate.
Of course, Kokichi instantly noticed the change, beginning to thrust his tongue in and out of Shuichi aiming just for the boy’s sweet spot. Shuichi let out a watery moan, rutting his hips downwards, eyes rolling back from the pleasure he oh so shamelessly drowned in.
“Kokichi~ ‘m gonna cum-” Shuichi cried, letting out a sob as Kokichi immediately pulled away his tongues and touches, licking his lips erotically.
“You taste good,” Kokichi offered. “I do wanna see you cum, but I want it to happen while buried in your ass more.”
“I don’t have any condoms, or lube on me,” Shuichi offered, meeting Kokichi’s eyes with a pitiful, apologetic expression.
Kokichi quirked a brow. “Well, I don’t give a fuck. Better lube my dick up real nice with your spit, unless you just wanna mutually masturbate or some shit.”
Shuichi considered his options, embarrassed whine pushed from his throat. Wordlessly, he slipped off his stool, glancing at Kokichi’s hard on and thickly swallowing. Gingerly, Shuichi pulled down Kokichi’s pants and obnoxiously colored underwear, staring cross eyed at the large package that sprung free. “I- can’t fit that!” Shuichi protested, lower lip quivering as Kokichi pushed his hat away to intertwine his fingers in Shuichi’s navy locks.
“You don’t know till you try~” Kokichi giggled, softly pulling Shuichi’s head forwards. “I might be above average, but you’re an above average whore, so it all works out in the end, nishishi!”
Shuichi nodded slowly, accepting Kokichi’s attempt at comfort as he pressed his lips to Kokichi’s tip, slowly wrapping around his head. The taste of precum dominated Shuichi’s tongue, yet he found he didn’t hate it, in fact quite the opposite. Needy for more of that wonderful taste, Shuichi hollowed out his cheeks, milking as much as he could out of Kokichi’s head. Slowly, he worked his way forwards, whimpering as his mouth was consumed by Kokichi’s girth. Shuichi tried to remember everything he knew about giving blowjobs, lapping at the underside of Kokichi’s length while he convinced himself to move down farther. Soft gags constricted his throat as Kokichi’s head reached the back of his throat, a low whimper reverberating the criminal’s dick.
“Fuck, Shumai,” Kokichi whispered, grinding against the ridges of Shuichi’s throat. “You seem pretty good at this~ you been giving a bunch of guys blowies without me knowing about it? Nishishi..”
Kokichi’s signature laugh was halfhearted, breathy pants breaking through his poker face as Shuichi ambitiously dove down farther, taking another inch, much to Kokichi’s enjoyment. Shuichi’s dick twitched at the scenario, used as a fuck toy by some murderer, pressed thrush against the ground on his hands and knees while he desperately pleasured the man above him. Maybe Kokichi was right about the danger kink.
After what seemed like an eternity, Shuichi’s lips pressed against Kokichi’s base, nine inches of pleasure constricting his throat. Shuichi desperately gasped his air through his nose, peeking up at Kokichi as he silently begged for validation. Kokichi smiled almost sweetly, petting Shuichi’s head and sifting through his hair.
“Think you’ve slathered my dick good enough to fuck you yet?” Kokichi purred, yanking at the roots of Shuichi’s hair while the masochist moaned. Desperately, Shuichi nodded, only jostling the cock sitting in his throat. With a pleasured hiss and a single bob of the head, Kokichi pulled out, slick sounds following his exit. Drool dribbled out of Shuichi’s lips, a dazed look on his face while he stared at Kokichi’s dick, leaning forwards as if following the appendage.
“Mmm, fuck me, please,” Shuichi begged with a slightly raspy voice.
Kokichi smirked, slipping around Shuichi’s body and grabbing his hips, forcing Shuichi to bend to his desired shape. Kokichi pressed his head to the ground, leaving Shuichi ass up balancing on his hands and knees. With a rush of sadism, Kokichi slapped Shuichi’s ass, whistling as the officer yelped and the fat of his muscle jiggled.
“W-what was that for?!” Shuichi exclaimed, pouting as he stared back at the criminal.
Kokichi shrugged. “Just wanted to do it! What, do I have to explain myself to you now?”
“No, but-” Shuichi was interrupted by his own gasp as Kokichi pressed his tip to Shuichi’s twitching hole, grinding his precum against Shuichi.
“I’m gonna go inside, you ready?” Kokichi asked, grinning as Shuichi fervently nodded.
A strangled moan was torn from Shuichi’s throat as Kokichi thrusted all of his length into Shuichi at once. Kokichi groaned from the tightness of Shuichi’s heat, gripping his cheeks possessively as he relished in the beautiful control he held. Once Shuichi’s sounds of pleasure devolved into whimpers and twitches, Kokichi began to slowly pull out, enthralled as he watched his dick appear out of Shuichi’s intestines. He kept moving his hips until even his tip slipped out, then rammed forwards, ruthlessly and sadistically filling Shuichi and rocking him so hard Kokichi was sure Shuichi would be feeling it for days. Of course, that didn’t stop him from doing the same thing over and over, throwing his head back as he relished in the pleasure flowing through him from where Shuichi’s tight ass squeezed him.
Tears incessantly slipped down Shuichi’s cheeks, eyes rolling back as his brains were fucked out of him. It hurt, but it hurt so *good*. Shuichi could barely believe that he was getting his ass pounded right now, but the overwhelming sensations only proved that this wasn’t some long winded wet dream. Every one of Kokichi’s thrusts filled him entirely, so much so Shuichi vaguely wondered if he had a belly bulge. His dick twitched against his stomach, precum slipping down to the floor while Kokichi rammed him open. It was the best Shuichi could remember feeling in a long time, all his thoughts and worries flying out of his head with every snap of Kokichi’s hips.
“Kokichi~ you’re so good at this~”
“And you’re good at taking me, hahh, slut. You’re so tight, shit-”
With a final thrust, Kokichi moaned, cum splattering through Shuichi’s insides and covering his prostate. The sensation lead him to his own orgasm, Kokichi’s hand covering his tip so cum didn’t explode against the floor and incriminate them.
Exhausted, Shuichi rolled onto his back, panting as Kokichi slowly pulled out and made the two of them decent.
“Shumai, look at me,” Kokichi demanded, smirking as Shuichi thoughtlessly obeyed his order. Slowly, Kokichi brought his hand up to his mouth, licking the semen off his hand in an erotic display Shuichi wished he could see again and again, for the rest of eternity. “You’re hard again!” Kokichi cackled, pointing at the tent in Shuichi’s pants. “Oh my god, I can’t believe you! Do you like my dick that much?”
Quietly, Shuichi whimpered, blushing and covering his face, mumbling something unintelligible.
“Hmm? Speak up, my beloved!”
“Y-yes…”
“Ain’t that cute~” Suddenly, Shuichi could feel Kokichi’s warm breath against the shell of his ear, teasing him and causing his dick to give a small twitch. “We’ll just have to do this again sometime, won’t we?”
When Shuichi peeked through his fingers, Kokichi was already seated again, clasping the last of his handcuffs together. Shuichi only received a sultry wink before the door slammed open and Kaito burst in.
“Shuichi!! I got her a book on space! Do you think she’ll like it?!”
“...She’ll love it, Kaito.”
“Huh? Why’re you on the floor?”
“Ah- um-! No reason!”
