Work Text:
Kakashi knows he's made a mistake before his hand finishes closing around the smoke bomb aimed at his face, and even though he hurls it away from himself immediately, leaping back from the fine purple mist streaming into the air, the slippery oil on his fingers tells him he's too late.
Ah. Damn. Maybe Tenzo had been onto something when he'd insisted Kakashi needed to take a break. Not that Kakashi will be telling him as much.
There’s a rustle ahead of him - his target, trying to take advantage of his distraction to escape - and Kakashi doesn’t bother to give chase, instead reaching casually into his pocket for the scroll to summon his ninken. Already, he can feel a stirring in his blood, his body temperature rising in response to whatever he’s been dosed with, and once he’s sent his hounds after the fleeing nin he tugs his mask down, tipping his head back and taking deep, deliberate breaths of the humid night air.
The forest around him smells of wet foliage and smoke and dog, but lingering under all of it is an unfamiliar sweetness, the last traces of whatever is currently working its way through him. Kakashi sighs. The particular poison might be unfamiliar but its effects certainly aren’t; you never really forget the feeling of a medical-grade aphrodisiac. Unfortunately, ‘Antidote for Sex Poison’ isn’t something he usually bothers to keep in his kit - not for this type of mission, anyway - so he takes a long pull from his canteen and crunches a soldier pill between his teeth and hopes that maybe, between his mask and his quick reaction, he managed to avoid the worst of it.
It isn’t long before the echoed chorus of a successful hunt rings through the forest. Kakashi ignores the sweat on his brow and the itch of clothing against increasingly sensitive skin and sets off after his dogs.
He finds his pack ringed around a twisted old tree, a young woman seated among its gnarled roots. She doesn’t notice his approach, and if it weren’t for her picture in his Bingo Book and the slashed hitai-ate tucked into her belt, he would almost mistake her for a civilian. This is Suna’s missing toxicologist; a genius even among a people famous for their skill with poisons.
“It won’t kill you,” is the first thing she says when he drops down from the trees to stand in front of her.
“Maa,” Kakashi drawls, slouching to tuck his hands into his pockets. His fingers curl around the familiar spine of his book and he focuses on the hard, straight edge of it to ignore the way his heart is beating quicker, the rush of his blood loud in his ears. “What’s the point then?”
“Just wanted to slow you down,” the missing-nin says wryly, dropping her head back against the tree behind her with a quiet thunk. “Can’t blame a girl for trying.”
“Should have used something deadly, then. It would have worked.”
The missing-nin closes her eyes. “I’m not a killer.”
Kakashi hums, noncommittal. She might not like to get her hands dirty, but Kakashi had seen a heavily-redacted list of the toxins she’s been responsible for brewing for Suna. In a lot of ways, she’s a more prolific killer than Kakashi himself. “Any chance you’ll hand over the antidote?”
The nin barks a laugh. “What antidote? Go find a willing hole and bang a few out, burn it from your system. You’ll be fine.”
Kakashi grits his teeth behind his mask, but keeps his voice light. “And let’s say, for the sake of argument, that I don’t do that?”
She shrugs, careless. “Then you’ll find an unwilling one, whether you want to or not. But you’ll survive. That’s more than I can say about this encounter, right?”
It's exactly what he hadn't wanted to hear. “You really should have used something deadly,” Kakashi tells her again, resigned, and draws a kunai.
-
Kakashi’s resolve to wait out the poison’s effects somewhere isolated lasts less than an hour. By the end of it, he realizes that he’s nearly reached the gates of Konoha without consciously deciding to return there, his mind swimming in a purple-tinted haze, instincts coming to the forefront to demand that he get somewhere safe. Konoha hasn't always been that for him, but things have changed in the last few years.
He reaches the village in record time, chest heaving with something more sinister than exertion, and scales the wall in powerful bounds, landing on the roof of an inn just inside the village proper. He crouches, masking his chakra, as a pair of patrolling guards pass by beneath him. If they find him in this state they'll take him to the hospital, and that's not what Kakashi wants. It's not what he needs.
The moon is heavy in the sky above him, the smooth tiled roof still sun-warm under his hand, and there is something vicious and animal stirring to life in his chest, something awakened by the poison but not brought on by it. Kakashi’s teeth ache in his mouth.
He should go to Gai. He trusts the other jounin, loves him like the brother he's been even when Kakashi didn't deserve it, and he knows with an unshakeable certainty that Gai would keep him safe, keep anyone from taking advantage of Kakashi when his mind is not his own. Knows, grimly, that he's strong enough to keep Kakashi from taking advantage of anyone in return. It's the most rational choice. The responsible one.
Kakashi does not go to Gai. Instead, he launches himself to the top of a nearby telephone pole, sprinting along its sturdy cable to the neighboring building and leaping from its roof to the next. The village blurs past him, and he doesn't know if it's his speed or the poison burning along his nerves that's making everything soft and smeary like running paint, but he knows this route by heart, has taken it beaten and bloodied and concussed, and his steps don't falter.
The animal in him is rumbling its approval, urging him on, all teeth and hunger in the moonlight, and Kakashi is clinging to the last of his reason with everything he has but this, this is not something he can stop. He's been drawn to Naruto for far longer than tonight.
It's like he blinks, and a familiar residential building is looming in front of him. He takes a running leap at it, sticking with his hands and feet and clambering ungracefully up the side. His pulse hammers in his cock like a wardrum, driving him on, and when he reaches the window he's aiming for he throws up the sash without pausing, too desperate to be cautious.
A kunai embeds itself in the wooden frame a hair's breadth from the fingers he curls over the sill, but Kakashi doesn't, can't, slow down, hefting himself up and into Naruto's darkened bedroom in one fluid movement.
“Sensei?” Sleep drags over the rasp in Naruto's voice and shreds it. A shudder wracks down Kakashi’s spine. “What the hell?”
There's a click, and amber light spills across golden skin and golden hair. Kakashi squeezes his eye shut, trying to clear his hazy vision, trying to recover from the way Naruto is literally glowing in the dim room. When he opens it again, Naruto is standing in front of him. He swallows, clenching his fists. Now that he’s here he wants, more than he’s ever wanted anything, but he doesn’t know how to get from where he is, standing before Naruto, strung wire-tight and aching, to where he needs to be without just taking it, without just shoving him back onto the mattress and crawling over him, without pinning him down and -
“Kaka-sensei.” The ridiculous nickname brings him back to himself, a little. His blood is rushing through him, heavy and hot, burning up through his skin in a heat-haze, taking his thoughts with it. He knows what he must look like; skin flushed, sweat dripping from his temple to soak the fabric of his mask, wracked by tremors he can’t control, and Naruto’s concern is clear in his eyes, in the cautious way he doesn’t reach for Kakashi despite the flexing hands that betray his restraint. “Are you drugged?”
Kakashi nods. He can manage that much. Barely. The animal in him is growling, clawing him apart from the inside. His dick throbs.
“Need me to go get Sakura-chan?”
“No,” Kakashi snarls, startling them both with his vehemence. The thought of Naruto leaving is too much. He can’t go anywhere, not now, not when Kakashi needs him. The idea of anyone else seeing him like this, all goldglow skin and a voice begging to be broken over Kakashi’s cock - he wouldn’t make it as far as the window. Kakashi wouldn’t allow it. “It won’t -” he stops, swallows around the growl still vibrating in his throat. “It’s not going to kill me.”
Naruto pauses, and the weight of his gaze is heavy suddenly, stroking over Kakashi like a physical touch, stripping him bare. Kakashi drops his head forward, hips rolling against nothing as lightning sizzles down his spine. Fuck, Naruto isn’t even touching him yet, but just the anticipation feels like too much. He’s still looking at the floor when bare feet step into view, and despite the way he shifts his weight, unsure, Naruto’s voice is all brash confidence when he says, “You’re here to fuck me.”
He’s always been so intuitive, always understood people on a level most wouldn’t bother to, and it’s no surprise that he’s cut to the heart of things, direct as ever. Kakashi is a master of obfuscation, but Naruto has never let him hide.
“If you’ll let me,” he forces himself to say, to offer one final out even if he has no idea how he’ll follow through on it if Naruto refuses him, if he tells him to leave. Naruto is strong enough to stop him if he has to, if he wants to badly enough, and Kakashi doesn’t want to fight him but he’s afraid that he will, afraid that he’ll take what isn’t on offer because the boundary between want and need is a scuffed line in the sand he can’t even find anymore.
“Idiot,” Naruto scoffs, and then he’s reaching for Kakashi, closing the space between them, his body a blaze of heat Kakashi would die to feel against his skin.
The moment Naruto touches him, the last, pitiful vestiges of Kakashi’s restraint are torn to nothing, shredded by monstrous teeth as he grips Naruto by the hips and jerks him sharply into his body. Naruto gasps, grabbing at his shoulders for balance, but he doesn’t push Kakashi away, wrapping his arms around his chest to hold him close as Kakashi ruts against him, grinding the bulge of his clothed cock against the ridges of Naruto’s abdomen.
He’s aware that he’s whining, hunched over Naruto and clinging to him like he’ll fall to pieces if there’s any space between them, his hips working frantically, but it’s distant, unimportant in the face of the molten-hot pleasure building in his core, surging up his spine. His skin tingles, sensation skittering across it, setting his hair on end and his eye rolling, tongue hanging out of his mouth to press against the fabric of his mask while he humps Naruto like a dog. Naruto drags his hands down his back, over the bulk of his jacket, to grab handfuls of his ass and haul him even closer, and there’s a leg shoving up between his thighs and Kakashi shudders, silent, as he comes in his pants like the teenager he’d never allowed himself to be.
“Fuck, Sensei,” Naruto groans, his own cock straining against the front of his ramen-patterned boxers, and Kakashi can’t get enough air, can’t catch his breath as the need in him burns higher, brighter than before. The animal in him howls, far from sated. “That was so hot. Maybe go a little slower next time, though, huh? I didn’t even get to -”
He cuts himself off with a yelp as Kakashi hooks his hands around the backs of his legs and hefts him up and back, throwing him across his bed. “Kaka-” he manages, and then Kakashi is climbing over him just the way he’d envisioned. Naruto’s thighs fall open for him and he slots himself between them, eager and hungry, only to be stopped by firm pressure against his chest. “Clothes, Sensei,” Naruto reminds him, ignoring his impatient growl in favor of getting his flak vest open and shoving it over his shoulders.
Kakashi sits back on his haunches so Naruto can work the vest down his arms, then crooks his fingers under the loose fabric of his shirt and tears it over his head, shuddering at the feeling of cool air on his sweat-sticky skin. Strong hands tug the clinging material of his sleeveless undershirt up his heaving belly, stroking over his skin, driving him out of his mind, and when Naruto’s clever fingers brush his cock he snarls, wrapping his hand around the younger man’s wrist to drag his palm firmly over himself, letting Naruto feel the heft of him, the way he’s throbbing in his pants.
“Fuck,” he grits out, rolling his hips into Naruto's grip as he squeezes him. “Gonna come again.” It’s inevitable. The heat in his blood is rising, one wrong breath from boiling over, and he's been drugged with an aphrodisiac before but it wasn't like this. Nothing has ever been like this.
“Jeez,” Naruto mutters, face screwed up in some weird mix of awed and horny that shouldn't send Kakashi’s heart tripping over itself like it does. The flash of pink tongue at the corner of his mouth makes Kakashi jerk, dick spitting more mess into his ruined pants. “Hang on a sec. It'll be even better if you just-”
He doesn’t finish, because he gets Kakashi’s pants open then and the sudden release of pressure snaps the coiled heat in his belly like springing a trap. Wet surges up his cock to streak across Naruto’s skin in pearly ropes and Kakashi’s back bows, arching in a crack of lightning down his spine as Naruto wraps a calloused hand around his twitching dick and roughly strokes him through it.
It's better this time, more intense with someone's hand on him, every nerve sizzling from the skin on skin contact. The sensation is bright white and blinding, almost too sharp to be called pleasure, his body tensing in harsh pulses, and it seems to last forever, the powerful surges fading gradually into loose-limbed little shudders.
“Neat trick,” Naruto says, once Kakashi is slumped above him, taking desperate gulps of air and shaking through the overstimulation. His grin is wide and cocky, smugly self-satisfied. “Gonna go for three?”
“Maa, Naruto.” Kakashi pouts beneath his mask, the effect somewhat ruined by the way he's still panting. He's feeling a little more level-headed at least, now that his jizz is smeared over his former student's skin, the beast in him rumbling in satisfaction at the scent of them together, heady in his sensitive nose. He sees, now, why his poisoner had insisted he would need a partner. “Making fun of your poor old sen-”
He chokes on a wheeze, brain short-circuiting, when Naruto drags his hand through the mess on his stomach and brings it, wet and shiny with Kakashi’s spend, to his mouth. That plush pink tongue makes another appearance, stroking slowly up the length of his fingers to taste Kakashi on them.
Any sense of self-control he's been clinging to evaporates in a puff of smoke. Kakashi surges forward, catching Naruto by the wrist and pinning him to the bed, caging his body beneath his own, and Naruto’s grinning his fox-grin up at him, eyes shining like he’s gotten exactly what he wanted.
He has no idea.
Kakashi brings his hips down, rolling them firmly against Naruto’s hard dick as he leans in, slow and deliberate. This close, he can see the sweat beading on Naruto’s skin, the traces of stubble roughening his jaw, the flutter of the too-fast pulse in his neck. He watches him swallow, throat bobbing, his smug smile fading, and then leans closer still, until their mouths are a breath apart.
“Kakashi,” Naruto breathes, shivering, but when Kakashi releases his arm to reach for the fabric of his mask Naruto grips his wrist, stilling him.
“Not like this,” he murmurs, voice rough, turning his head to drag his lips and tongue along the seam where flesh and cloth meet, hot and wet, making Kakashi’s gut clench. Kakashi tries to tear the mask off anyway, wanting to taste him, but Naruto's arm bulks, holding him in place. The sensation makes the beast in him rumble approval, makes his hips rut mindlessly down into the crease of Naruto’s thigh, smearing precome over the wet fabric of his boxers.
“Naruto,” Kakashi gasps, feeling the younger man's free hand tugging at his open pants, working them down his hips. He won't be able to get them off with Kakashi’s calves wrapped in bandages the way they are - and Kakashi is well past capable of pulling away to undress himself - but he seems satisfied leaving him stripped to mid-thigh.
“If you still want to show me your face when the drugs wear off, I'll be here,” Naruto says, firm despite the whine in his voice, his hips bucking up to rut his cock against Kakashi, a motion Kakashi eagerly meets with a hard thrust of his own. “But not like this.”
It's frustrating and earnest and almost unbearably kind, much like Naruto himself, but it's a misplaced gesture. Kakashi wears his mask more out of habit than anything, because the myth his one-time students have made his face into is as funny as it is endearing. He has no hang-ups about his features or letting himself be seen, but if Naruto would feel better waiting, Kakashi will not deny him.
He'll just have to make sure to taste him thoroughly later.
Kakashi isn't sure what happens to Naruto’s boxers, too caught up in Naruto's mouth when the younger man scrapes his teeth over the arch of his cheekbone and drags them to his ear to bite at his lobe, but one moment he's rutting against cloth and the next his cock is smearing over sweat-tacky skin. He hunches over Naruto, back bowing as sensation screams along his nerves and fire spills from him to splatter over Naruto’s dick.
“Did you just -”
“No,” Kakashi snaps. He’s shaking like he'll come right out of his skin, his heart beating fast enough, hard enough, to burst. It feels like he’s going to die and he needs, he needs - “Gotta fuck you.”
Naruto makes some kind of needy, approving noise but Kakashi is barely paying attention to him, focused on hooking a hand under his knee and pressing up and out, opening Naruto’s powerful body up wide. He’s beautiful like this, gleaming and golden, his flushed cock leaking steadily into the cut lines of his heaving abdomen, his sac resting heavy against the plump, plush skin of his perineum. Kakashi’s attention tracks lower, drawn to the furl of his hole, rose-dark and tempting. It twitches when he presses his fingers to it, so receptive, and his cock is throbbing, spilling wet with every pulse, aching to be inside.
And then Naruto is pulling away from him and Kakashi growls, the sound ripping from him with an animal's violent intensity. He drops his body down over him, pinning him to the mattress, and all that sudden skin contact, plastered together from his cock to where his undershirt is rucked up beneath his arms, is almost his undoing.
It feels so good, touching Naruto is so good, every nerve singing in a relief and an ecstasy that he can’t blame entirely on the drug. He’s been dreaming about this with a shameful, feverish sort of obsession, the kind he’s always associated with the worst parts of himself, the kind never meant to see the light of day, but Naruto’s body is rocking against his and there’s no mistaking his thundering heart or his twitching cock for anything other than equal desire.
And still he’s trying to pull away.
“- just for a second, dammit. You’re not sticking that in me without lube.”
Oh. Slowly, reluctantly, Kakashi eases his grip on Naruto, lifting himself just enough that the other man can twist around and tug open the drawer on his nightstand, fishing around with an expression of intense concentration. Kakashi rocks his hips, sliding his cock through the crease of Naruto’s ass, and he curses but a moment later pulls his hand free with a crow of victory, a small bottle clasped between his fingers.
It’s almost empty.
Fury is a flashfire sparking to life in his chest and he snarls, baring his teeth, ignoring the way his incisors catch on the wet fabric of his mask. His vision is blanketed in a red haze and he tightens his grip on Naruto, ignoring his sound of protest, yanking him back onto the mattress and further beneath Kakashi’s body, heart hammering because somehow, in the midst of all of this, he’d never considered that he might have a rival - or even rivals - for his place in Naruto’s bed.
“You’ve been fucking -”
“My hand,” Naruto cuts him off, knocking the bottle against the knuckles of Kakashi’s shaking fist until he forces himself to uncurl his fingers and take it. “Possessive bastard. Fuck, why is that so hot?”
Kakashi doesn’t know. He doesn’t care. The only thing that really matters is that he still has a chance to claim Naruto for himself, to fuck him so well that he’ll never go seeking anyone else. That he can still be Kakashi’s.
He’s wasted enough time. He grips Naruto by the hips and flips him onto his belly in one quick move, pausing just long enough to strip off his gloves before dumping the last of the lubricant over his fingers. He lays himself across Naruto’s back and nudges his way into the crease of him, stroking over the velvety skin of his hole, smearing it with slick.
“Hold yourself open,” he commands, and Naruto curses shakily but does as he’s told, gripping his rounded cheeks in both hands and spreading his ass wide. “Good,” Kakashi tells him, and then rewards him by biting at his shoulder through the mask. Naruto shouts, just as loud as Kakashi had always imagined he would be, tension snapping down his spine, but a moment later he blows out a shaky breath and relaxes, loosening enough that he can work the tip of his finger past the protective ring of muscle and into his burning body.
Kakashi doesn’t intend to spend a lot of time here, too needy and overwhelmed to hold himself back, but Naruto is more responsive than he ever imagined, gasping and shaking, whining at every touch, and he loses himself in it, stroking at the blood-warm silk of his insides and working his knuckles against his rim, opening him slowly, deliberately. The sound of his name in that full, husky voice is better than music, better than every fantasy he’s ever had and he’s had so many; shameful, secret dreams, alone in the dark.
He doesn’t know how much time passes and it doesn’t matter. The poison burning through his system, his throbbing cock, it all falls to the wayside, somehow less important than the way Naruto is cursing and rocking back into him, the muscles in his back rippling with every slow curl of Kakashi’s fingers, his hole sucking at them greedily. Kakashi noses along the length of his neck, the smell of him overpowering and heady, salt and spice and musk, the fabric of his mask soaked through with their sweat and the spit from Kakashi’s hanging tongue.
“‘Kashi,” Naruto finally grits out, shoving himself onto Kakashi’s probing fingers. “What’re you waitin’ for? Fuck me already.”
Any other night, any other partner, and Kakashi would take that bratty demand as a challenge, would draw things out just to tease, just to punish him for his impatience. But tonight he is more animal than man, and Naruto is only giving voice to the wordless, rumbling growl in his own mind, and he’s already been pushed well past the limits of his restraint. Tonight, he needs to fuck.
He crooks his fingers, pressing mercilessly against the swell of Naruto’s prostate, and when Naruto shouts, shocked, spine arching and legs jerking at the sharp sensation, he pulls his hand free and replaces it with the scarlet head of his cock, pushed proudly out of his foreskin and drooling onto Naruto’s swollen, twitching rim. He doesn’t give him any time to recover, just shoves himself past that lax ring and into the burning bliss of his body.
Naruto arches, still so tight, straining around him, and Kakashi pulls back just to fuck in deeper, splitting him open, carving a space for himself with every ruthless drive of his cock. Beneath him, Naruto is shaking and twisting, letting go of his ass to fist his hand in the sheets, tight enough that the fabric tears, and he’s hollering Kakashi’s name to the heavens, so loud that by dawn the entire building will know who Naruto belongs to.
The animal in him is snarling, vicious and victorious, and Kakashi adjusts his stance, braces his knees on the outside of Naruto’s thighs, and shoves himself to the hilt in Naruto’s ass. Naruto cusses at him, body bucking, but Kakashi bears down on him, reaching up to fist a hand in golden hair and shove him face down into the blankets. With a full-bodied shudder, the last of Naruto’s resistance gives way, his body going loose to accept him, and Kakashi seats himself, hips flush against the plush swell of his ass.
“That’s it,” he hisses against a flushed ear, voice a knife in the dark. “Take it.”
Naruto makes a sound that’s very nearly a sob, and fierce satisfaction burns down Kakashi’s spine to his gut, oil to the flame of his arousal. He grinds himself deeper just because he can, because the beast in him is demanding that he split Naruto’s skin open and crawl inside of him to stay, and he pulls his hips back and fucks in again, and again, and again, while Naruto tilts his hips up and takes him like he was born to.
It feels so fucking incredible, Naruto’s body a perfect little sleeve for him to use, and he can’t stop his mouth from running, can barely make out his own words over Naruto’s cries and the hammered-drum beating of his heart. “This is what you needed, isn’t it Naruto? What you’ve always fucking needed.”
Broad shoulders bulk as Naruto tries to lift his head but Kakashi tightens his grip on his hair and holds him in place, leaning more of his weight forward to keep his chest to the mattress. It changes the angle Kakashi’s getting him at, and he can feel the way he’s stretching that abused rim, can feel the strain of it pulled taut around the underside of his cock. It’s exquisite, stroking along the length of him with every thrust, sending crackling lightning over Kakashi’s skin, so sharp and potent he could almost mistake it for his own chakra.
It’s good for Naruto, too, who howls as Kakashi catches his prostate on the second thrust. He finds it again, then intentionally misses it on the fourth, and the fifth, until Naruto whines in protest at the denial.
“I asked you a question, Naruto,” he grits out, following the statement with a vicious series of thrusts that has them both groaning, pleasure searing Kakashi from the inside out.
Naruto makes a muffled noise and Kakashi allows him to turn his head enough that he can speak. The half of his face that’s visible is flushed and messy, shining blond hair plastered to the dripping sweat on his forehead, and his eyes are wet, lashes spiky, drool smeared across the trademark scars on his cheek. He’s devastating, and Kakashi wants to devour him, wants to fuck him until his heart gives out. “Wha?” he manages, tongue lolling clumsily.
“I asked,” Kakashi snarls, “if this is what you need. To be held down and fucked, to be taken, to be used.” Naruto’s visible eye rolls back as Kakashi nails his prostate again, mean about it, not giving him the chance to deny what they both know. “You’ve always been such a brat, so loud, demanding my attention even when I wasn't your teacher anymore, but this is what you were really after, isn’t it? You needed my cock.”
For a moment, he doesn’t know if it’s too far, if it’s too much. Naruto is stubborn and proud and loath to admit that he needs anyone or anything, but like always, he surprises him, the last of the tension draining from him like blood from a fatal wound, leaving him limp and trusting in Kakashi’s hold.
“Yeah,” he gasps, eye seeking Kakashi’s and finding it. It’s so blue, such a vivid, unmistakable color, a reminder that it’s Naruto he’s fucking, Naruto submitting to him, Naruto confessing that he needs Kakashi’s cock. That he has always needed Kakashi’s cock. “Kakashi, Sensei, need it please, please -”
The words die on a choked noise when Kakashi presses their open mouths together, lips and tongues meeting through the heavy fabric of his mask. Naruto whines, trying, instinctively, to chase the movement of his tongue under the cloth, their trapped breaths heavy and humid between them. Kakashi aches to taste him, his teeth huge in his aching jaw, as he hammers Naruto's prostate again and drinks his cries directly from his mouth.
He pulls back as his orgasm begins to build, hot as molten steel in the core of him, different than the ones that came before. He knows that it will be the last, that the poison in his system has worked its way out of him, that the only thing driving him to fuck Naruto right now is his own desperate desire.
If this is the only time Kakashi gets to do this, he's going to make it count.
He gets his feet under himself and lifts his body, keeping his fist in Naruto's hair to hold him in place as he bullies his hips up, forcing his back into a beautiful, perfect arch. Naruto lets him, so pliant, so good, offering up no resistance as Kakashi bends over him and nudges his cock back into place.
This time when he fucks into Naruto he's driving down; short, sharp thrusts, fast and hard and so fucking good. It isn’t long before Naruto is shouting again, a garbled mess of Kakashi’s name, and ‘sensei’, and ‘moremoremore’ that has Kakashi’s blood boiling, and as his impending orgasm knots the base of his spine, made malleable by the sheer heat of his desire, he relinquishes his hold on Naruto’s hip to reach around the front of him.
The younger man’s cock slaps against the backs of his knuckles as he fucks in again, and Kakashi wraps his hand around him, feels how hard he is, blood-hot and weeping precome. It makes him croon, makes fire tear through him, makes the beast in him roar. “Look at you, you need it so bad, hm? You’re so close, baby, but you need a little more, right? Need Sensei to help you get there.”
It’s filth, dragged up from the darkest parts of Kakashi’s mind, the parts of him that he’s never quite managed to kill. Naruto makes a wounded noise, but bent the way he is, trapped and held in place and made to take what Kakashi gives him, he can’t thrust into the tight ring of Kakashi’s fingers. Can’t find the release he needs.
“Kakashi,” he whines, mindless, his eye hazy and unfocused, the sheets under his cheek darkening with tears and sweat and drool. “Please.” Kakashi ignores him for a moment, caught up in the way his hole is wringing at him, so unbearably greedy despite the lube and precome that splatter out of him with every thrust. “‘Kashi, please.”
“Yeah,” Kakashi tells him. “Come on my cock, Naruto.” He couples the command with a harsh stroke of Naruto’s cock, his grip tight, callouses rough against silk-thin skin, and just hours ago Kakashi’s hands had taken a life but now they send Naruto, screaming, into ecstasy, his body tensing again and again as Kakashi pulls spurt after spurt of come from him.
The sound and feel and scent of his pleasure are too much, fanning the flames of Kakashi’s need until he’s entirely consumed, and he increases his pace, forcing Naruto to take his weight as he fucks him with vicious, digging thrusts, mindless and frantic as a dog as Naruto shudders beneath him. The tension in his spine snaps, but the sudden release of pressure only spurs him on, their skin slapping together as he pounds his spurting come into Naruto’s greedy ass, burying it deep, fucking in more and more until it’s overflowing, making a foamy ring around the base of Kakashi’s cock and drooling down his balls.
The pleasure is white-hot, burning out his nerves and blasting apart his mind, and for a moment his perfect control slips, chakra sizzling in the air, drawing a shout from the man beneath him as lightning arcs between them. From the way Naruto tenses around Kakashi, the way the smell of his come grows stronger, the sensation must draw another orgasm from him, and a beat later he collapses, boneless and completely spent, whining quietly in overstimulation as Kakashi continues to chase his own pleasure.
He only slows when there’s nothing left to give, when every drop of his come is where it belongs - on Naruto’s skin, in Naruto’s body - and then he slumps over him, chest heaving, body slick with sweat. It takes a lot to give Kakashi a real workout, but leave it to Naruto to push him past his limits.
When his heart feels less like it’s going to burst through his chest, Kakashi picks himself up, wincing when he has to peel his skin off of Naruto’s. Naruto grumbles at him, clearly feeling well enough to be difficult again, and Kakashi smiles beneath the filthy fabric of his mask as he carefully reaches between them to pull his soft cock from the ruin of Naruto’s ass. He takes a moment to appreciate the view, the way his foamy come drips down from that gaping hole in slow, sloppy strings, painting his flushed perineum and the insides of his thighs. He considers nudging up his hitai-ate to let the Sharingan eye record the image in perfect detail, but his exhaustion stops him. He’s exerted himself enough for tonight.
Once he gets Naruto laid out comfortably, he strips his pants off and then, after a moment’s pause, the undershirt that includes his mask. He uses the soft material to wipe at the disaster of come on Naruto’s skin, and then drops it onto the floor with a disgusting, wet sound. Cleanup is going to be a pain.
He debates bullying Naruto into doing it, then snorts at the idea. Maybe he can also teach pigs to fly while he's at it.
Feeling sleepy and sated and more than a little shaky, Kakashi climbs onto the mattress, draping himself over the other man, who huffs but doesn’t push him away.
“Mm, Naruto,” Kakashi yawns. “When are you going to get a bigger bed? The single means we have to lay in the wet spot.”
“When I have someone to share it with,” Naruto says, and despite his exhaustion, the challenge is clear in the wreck of his voice.
“Then we should go pick one out,” Kakashi tells him casually, trying not to let on how much Naruto’s response means to him.
Blue eyes fly open and Naruto sits up so fast he dislodges Kakashi, who rolls onto his side beside him, their bodies stretched out against one another. He’s very aware of the open window behind him - the easiest escape route - but he forces himself to stay. If you want something, you have to be willing to be brave for it. Naruto had been the one to finally teach him that.
“Kakashi, you -” Naruto jolts again as it finally registers what he’s looking at. “Your face! You uncovered your face!”
“Maa, Naruto, is it that much of a shock? Is it hideous? Should I cover it up again?” He’s teasing, and for the first time in a long time there’s no fabric to hide beneath when his mouth tips into a playful smile. Naruto gapes at him, greedily drinking in every detail. He reaches up with a shaking hand to brush his thumb over Kakashi’s chin, the beauty mark at the corner of his mouth.
“All the things I imagined under there, but I never figured you’d be beautiful,” he says, so genuinely awed that Kakashi’s heart aches. He knows that he’s handsome enough, but Naruto is gazing at him like he’s special, like he’s everything he ever wanted. He really can’t take it. That thumb moves to his lower lip, tugging it down. “You’ve got big teeth,” he says, and there’s heat in his voice when he says it, heat that’s mirrored in Kakashi’s chest as he leans into the touch.
“The better to eat you with,” Kakashi says, but it’s quiet, vulnerable. Naruto beams at him, so bright and sudden he almost thinks to check for the sunrise, as if the sun could ever compare to this golden boy.
“Not if I eat you first, Sensei,” he announces smugly, and then leans in to kiss him. It’s their first kiss, a little bit clumsy, fumbling and innocent and sweet, and when Naruto makes to pull back, Kakashi hooks a hand around the back of his neck to keep him where he is, just a little longer. When they finally break apart, Naruto’s eyes are lidded and his smile is smaller, but no less genuine. “Let’s look at beds first thing tomorrow, okay?”
“First thing? Can’t you let an old man sleep in?”
“You can’t be late if you stay here,” Naruto reasons, ignoring him, and then hooks his leg over Kakashi’s hip and settles back down, closing his eyes, by all appearances preparing to go right back to sleep. “So stay. My alarm is set for six.”
“Naruto,” Kakashi whines, but he lays his head down, curling his body towards Naruto’s so that they’re bent into each other like the two halves of a heart. “The shop isn’t even open at six.”
His response is a snore, and Kakashi smiles. Chalk one up for sex poisons. Maybe he’ll suggest it for the next installment of Icha Icha. He imagines Naruto’s response to that and grins to himself, utterly satisfied as he drifts into sleep.
