Work Text:
Kai can hear Dabi’s loud, thunking footsteps before he even reaches the door. He’s always dragging those stupid fucking boots, always taking his sweet fucking time ambling wherever he needs to go—he’s late again, for the third time this week.
Dabi sounds tired and annoyed when he pushes the door to the capo’s office open. “There some reason you need to call me in here so fuckin’...” Dabi pauses as his eyes land on the gun in Kai’s hand, trained right on the center of Dabi’s chest. Dabi looks him up and down, licking his scarred lips, a smirk tugging at the corners of his insolent fucking mouth. “...early.” He quirks an eyebrow, looking at the gun, then Kai. “Gonna shoot me now? That could be fun, I guess.”
Kai tries not to roll his eyes as he motions for Dabi to come in. “Close the door.”
Dabi does as he’s told—unusual, since Dabi seems to make it his life’s mission to disobey every order he’s ever been given. He turns to Kai and leans against the door. “Gonna tell me what this is about, boss?”
Kai keeps the gun leveled at Dabi’s chest, unwavering. “You’re late. Again.”
Dabi chuckles. “And that means you’re gonna shoot me? Pretty piss poor fuckin’ reason. Plenty of better reasons you could pick from.”
“I’m aware,” Kai says dryly. There’s plenty of reasons to shoot Dabi where he stands, and only a handful not to—one of which is that Kai enjoys watching him writhe and struggle and beg during each one of their trysts. “Come here.”
Dabi saunters over, boots dragging across the floor and Kai’s nerves, finally coming to a stop in front of his desk. Kai motions for him to walk around, to stand in front of him in his chair.
“Watch where you fuckin’ point that thing,” Dabi jeers as he does as he’s told for fucking once.
“Good to know you can behave under the threat of certain death,” Kai snips. “Take off your clothes.”
Dabi raises an eyebrow, snickering, still far too smug for Kai’s taste. “No foreplay today?”
Kai stands and pushes the barrel straight into his chest, eyes flashing. “I said off, Dabi.”
Dabi raises his hands defensively. “Damn, boss. Didn’t know you were in such a fuckin’ rush to get your dick wet.”
Kai sits back down, gun still pointed at him. “Hurry up, or my hand might slip.”
Dabi tuts. “Mm, fine, fine.” He shrugs off his jacket and lays it on Kai’s desk, watching him with those infuriatingly pretty eyes. Next to go is his shirt, stripped off and dropped carelessly on top of his jacket, leaving his bare chest and protruding ribs out on display, his scars a disgusting mess in the light of Kai’s office. He takes his time unbuckling his belt, holding Kai’s gaze as he pops the button and zip on his tattered jeans. They fall off his skinny legs too easily after he steps out of his boots, pooled on the ground around his feet. He gives Kai a sly smile as he shimmies out of his boxers, dropping them on the ground with his jeans.
“Get on your knees,” Kai orders, waving the gun. He eyes Dabi’s skeletal frame with disdain, curling his lip behind his mask as he watches him sink to his knees.
Dabi shrugs, unbothered by the fact that he’s little more than a bag of bones and sharp, unforgiving angles. “Could’ve just asked if you want me to suck your dick.” He crawls over to Kai, spidery fingers sliding up the insides of his thighs.
Kai shoves the gun into his temple and Dabi freezes for a split second before licking his lips, his eyes half lidded and slightly unfocused. “What? Don’t want me to suck you off now?”
“No,” Kai says. He tugs down his mask and leaves it under his chin, giving Dabi a sharp grin. “Not me.” He moves the gun again, holding it in front of Dabi’s mouth, prodding at his lips with it. “This.”
Dabi leans away, giving him a dubious look, his eyes flicking from Kai’s gaze to the gun and back again. “You want me to...what? Suck on your gun?”
“Yes,” Kai says simply. “And then I’m going to fuck you with it.”
Dabi stares, and Kai can practically see the cogs in his drug-addled mind trying to process this information. “You’re gonna...fuck me with your gun,” he repeats slowly. “You want...to put your gun in my ass.”
“Yes,” he says tersely. “Don’t make me repeat myself.”
Dabi nods, his unfocused eyes taking on a giddy sheen. Of course Dabi would be into something fucked up like this—Kai had a feeling he would be. In fact, nothing Kai does seems to ruffle the man, nothing seems to get under his skin, and Kai finds that utterly infuriating—which is what leads him to try and humiliate him with shit like this, like shoving his gun up Dabi’s ass just to watch him squirm.
“Prep yourself if you don’t want it to hurt,” Kai tells him. “You won’t be getting any from me.”
Dabi snorts softly. “Mm, course not. Wouldn’t expect shit from you.” He pops his fingers in his mouth, slicking them up with saliva, and a long string of spit connects his fingers to his glistening lips when he pulls them away and reaches between his legs.
Dabi licks his lips again as Kai holds the barrel to them. He watches that slutty little pink tongue run along the edge, lips parting to try and take it in his mouth. Kai smirks as he shoves it in without warning, earning a little mewl of surprise from Dabi’s throat, his staples straining in his face to accommodate the stretch of his mouth.
“Better start sucking,” Kai sneers. “You have one minute.”
Dabi pulls off and glares at him. “A minute? That’s not enough to—”
“Fifty eight seconds,” Kai says, and Dabi huffs in frustration. He can hear the sound of Dabi’s slicked up fingers working himself open, what little healthy skin is left of Dabi’s cheeks flushing a pretty pink as he eyes the gun again. “Fifty five seconds.”
“Okay, okay,” Dabi grumbles, opening his mouth again. His mouth slides further down the barrel, those blue eyes flicking up to look at him as he does.
Kai pushes it in a little more just to listen to him struggle, to watch his face screw up in concentration as he tries not to chip his teeth on it. Unsurprisingly Dabi lets out a moan a few seconds later, drool sliding down his chin as his hips rock back onto his hand.
“Disgusting,” Kai mutters. He can’t believe he spends so much time fucking this man—he’s fucking repulsive, and fucking suicidal for letting Kai do this to him.
Well. Not that Kai really gave him a choice.
“Forty five seconds.”
Dabi grunts, steadying himself with one hand gripping the inside of Kai’s thigh. Kai doesn’t even bother to hide the fact that his cock is half hard, pressing up against the inside of his trousers. He knows Dabi can see it, knows it’s part of the reason he’s slobbering all over himself—Dabi is always cock starved, always pawing at him for sex, always desperate to get fucked.
It’s vile—or at least it should be, but Dabi has a way of worming past his aloof exterior and into Kai’s life, of distracting him from his duties and dragging him into bed with him. He’d never admit to liking the way those scarred arms feel draped around his shoulders, or the way Dabi’s nails rake down his back when Kai fucks into him—because neither of those things are true. He doesn’t like them, doesn’t like Dabi at all.
At least...that’s what he tells himself, anyway.
“Twenty seven seconds.”
Dabi’s long white eyelashes flutter, another wanton moan bubbling up from his throat that goes straight to Kai’s dick. Kai nearly rips the gun from his mouth and Dabi splutters, drool sliding down his lips and dripping onto the floor. “Why’d you do that?” he grumbles. “Was jus’...doin’ what you asked, asshole.”
Kai gives him a tight lipped smile. “Changed my mind—time’s up. Stand up.”
Dabi rolls his eyes, retracting his fingers from his ass with a slick little pop. He pushes himself to his feet, his cock bouncing between them as he crawls into Kai’s lap. “Gonna fuck me with your gun now, boss?” he croons, swiping the drool from his face with the back of his hand.
Kai hums in response, looking at the gun. It’s wet, disgustingly wet, and he reaches behind Dabi with it, pressing it up against his hole. “Hope you did a good enough job.”
Dabi waggles his eyebrows. “Guess we’ll find out, won’t—” he stops, hissing through his teeth as Kai starts pushing it in. Dabi must not have tried hard enough because he’s met with some resistance, and the scarred man’s eyes squeeze shut as Kai shoves the barrel past his tight ring of muscles. “Fuck—ah, fuck, Kai, fuck…”
“I told you to prepare yourself,” Kai says smoothly. “Not my fault you don’t know how to do it correctly.”
Dabi cracks one eye open despite his pained expression, managing through gritted teeth, “S’not as good as when you do it.”
“Flattery will get you nowhere,” Kai says coldly, even though his chest surges with pride at Dabi’s little words of praise.
Dabi grunts, his eyebrows scrunching up in discomfort. Kai pushes in a little further and Dabi hisses again. “Fuck, man, gimme a second,” he whines.
Kai gives him a decidedly unimpressed look. “I told you, I’m not gonna wait for you to be ready.” He leans forward into Dabi’s space, close enough that their noses almost brush. He can hear Dabi’s breath hitch, feel his hips tremble in Kai’s lap. “I’m gonna give you one chance to make it good for me, and if I don’t like it, I’m going to fucking shoot you.”
Dabi’s eyelids peel back at that, those pretty blues popping wide open. “You’re…” he wheezes. “You’re gonna…while it’s still...inside...”
Kai leans away and smiles as it clicks into place in Dabi’s mind. “Yes. Now—come on, get to it. I wanna see you get yourself off this way.”
Dabi stares for a few moments longer, his long fingers stuck like claws into Kai’s shoulders. “Sick fuck,” Dabi mutters, but at least he does what he’s told—he lifts his hips and sits back down, biting his lip and groaning. Kai sits back and watches as Dabi slowly gets the hang of it, his thighs trembling with the effort as he fucks himself on the barrel of Kai’s gun.
Kai’s gaze drifts down Dabi’s torso, along the patchwork mess of skin, watching his clenching stomach muscles and finally looking at his cock. He’s hard and leaking, the tip flushed a pretty shade of red as it bounces between them.
“Touch me, Kai,” Dabi breathes, his teeth clenched as he struggles to keep himself balanced in his lap.
“And what if I don’t?” Kai says airily, and Dabi groans in frustration.
“C’mon, ‘m doin’ your stupid thing, help me out a little bit.”
“No,” Kai says, and Dabi huffs. Scarred arms slide around his neck and Kai tries to ignore how much he likes that feeling, how Dabi practically breathing all over him has him harder than he’s ever been for anyone else. “Do I have to remind you that I can and will kill you?”
“Yeah,” Dabi says, pressing his forehead to Kai’s. “That’s the best part—better tell me again.”
Kai narrows his eyes. He isn’t surprised, but also somehow can hardly believe that Dabi can actually get off to this. “Don’t make me fucking shoot you.”
Dabi pretends to pout, but it’s ruined by another moan, his pleasure obvious in his face. “Kinda wish you would.”
“You’re fucking sick,” Kai mutters.
“Mm, not any more than you,” Dabi grins. “You’re the one who—hnnghh—wanted to do this. S’all your idea, ya nasty fuck.”
“You’re so vulgar,” he says, and Dabi laughs.
“It’s why you like me so much.”
“I don’t fucking like you.”
Dabi laughs again, little more than a wheeze, pressing their lips together. Kai kisses him back harshly, biting and licking and sucking as Dabi continues haphazardly fucking himself. Soon enough Dabi is whining and whimpering, his hands fisted in Kai’s hair as his legs start to shake.
“Kai, please,” he breathes against his lips. “Need you to touch me, need it so fuckin’ bad, please—”
Kai reaches forward with his free hand, wrapping it around Dabi’s cock, letting him try to messily fuck into his fist and fuck himself on the gun at the same time. “Gonna have to fucking work for it,” Kai smirks. “Maybe I’ll still shoot you anyway—”
“Ah—hhh—fuck, Kai,” Dabi gasps, Kai’s threat finally tipping him over the edge. Warmth seeps into Kai’s glove as Dabi’s cock gushes all over his hand, dripping down onto his lap. Dabi’s hips swivel for another few moments before slowing, his breath rattling around in his chest as he finally stops.
Kai withdraws the gun and Dabi’s eye twitches, but he doesn’t complain. Instead he all but collapses in Kai’s lap, burying his face in his neck. One of Dabi’s scorching hands makes its way down his chest, palming at Kai’s cock through his trousers, and Kai groans at the contact. Dabi’s hands are hot and heavy and Kai is already dangerously close to coming, arching his hips into Dabi’s touch. Dabi easily works him out of his clothes, his long fingers wrapping around his cock, working him like Kai wasn’t just threatening to shoot him less than a minute ago.
“Do you need me to threaten to kill you too,” Dabi teases, but Kai is already there—he comes with a stuttered breath, coating Dabi’s fingers in milky white.
“Shut up,” Kai breathes, finally leaning back enough to look at him.
Dabi hums, lifting his fingers and loudly slurping the cum from them. Kai wrinkles his nose, but can’t tear his eyes away from the way Dabi’s tongue licks up every last drop. “That was fun,” he muses. He leans forward to press another kiss to Kai’s lips—one he only accepts because he’s still buzzing from his orgasm, not because he fucking likes him.
“Get out of my office,” Kai says, but there’s no real bite to his words. “And be on time for once next time.”
Dabi smiles, pulling back slightly. “Sure, boss. Whatever you say.” He slides off his lap, tottering on unstable legs as he redresses in front of him. Kai strips off his gloves—they’re fucking filthy, covered in cum, and he chucks them in the trash. He watches Dabi pull his jacket back on, his little smile replaced by that smirk Kai constantly wants to wipe off his goddamn face.
He saunters out as easily as he came in, tossing a wave over his shoulder as he walks out.
