A/N: This has been written for Kinktober 2021 and today's prompts are rimming & tickling ✨ Due to the nature of this challenge, I've only done the most cursory of proofreads.
Warnings/Content: at worst this could be read as extremely mild dubious consent.
The warmth of a night spent drinking in good company has worn the hard edges from his mind. They'll be back in a few hours but for the moment the worst of the pain becomes a blur, smothered into submission by the burn of liquor and the weight of Guy, slung heavy against him as they stumble back to Kakashi's home. Guy is shouting, impassioned, into the night sky, demanding a challenge on the way back to Kakashi's. He's learned far better than to take him up on it, between the two of them, Guy can certainly handle his liquor with more grace, insomuch as he handles anything with grace, which is to say none, but the change in behaviour is negligible. The thought that it's no wonder, given the size of him, flits idly through Kakashi's mind, drawing his eyes to the side, along Guy's broad chest. He knows better than to pursue that, as well.
"My dearest rival," he begins anew "I say we harness the power of this beautiful night, run the rest of the way and see whose youthful spirit remains strongest!"
"That sounds like a terrible idea."
"You haven't yet heard the prize." Kakashi turns a baleful eye on him. Guy grins, unrepentant.
"If you suggest push-ups-"
"You know me too well!"
"Unfortunately."
Guy's laughter booms into the night and Kakashi thinks that's the end of it until he shifts, quick as anything, and Kakashi feels thick fingers worm their way under his arms from behind. Stumbling forward he turns back to Guy with absolute composure "What was that?" Fearing the answer. The smile Guy wears is one Kakashi knows well enough. Nothing which has followed it has ever made Kakashi's life easier.
"If you won't accept my challenge, I'll force your hand."
Guy is hard headed at the best of time. Drunk and revved up, Kakashi has been here enough times to dread whatever madness his friend will throw the night into next. Still, a smile fights to break out under his mask. He's missed this.
"Oh? You think?"
"Ah, Kakashi. I will endeavor to enough enthusiasm for both of us!"
"I'm sure you will."
In a flash, Guy is there, Kakashi only barely moving out of the way in time to evade him, feeling where the tip of Guy's fingers brush the edge of his sleeve. Then they're off and Kakashi can hardly bring himself to be bothered by the fact that even if he hasn't caught him, Guy has already gotten his way.
By the time they reach his apartment, Guy has sprung up to surprise him enough times to make him break a sweat, forcing him to stay on track to his apartment. The door shuts hard behind him and he knows within seconds it hardly matters as Guy's weight comes barreling into him from behind, crushing him to the floor where he doesn't quite care enough to hold back a laugh. He expects Guy to pin him down, crow over his victory and shout triumphantly about the push-ups he'll make Kakashi do in the morning, and the ones he'll do himself twice as hard and twice as fast, simply because he can. What he doesn't expect is the calloused heat of Guy's hands shoving their way under his shirt to tickle at his ribs.
Even the indignant squawk which leaves him isn't enough to help convince himself he isn't staying where he is by choice.
"What-what the hell-" He gasps out between choked out laughs. His sides hurt but the scrape of Guy's fingers against his skin is enough to chase away any bother.
"Your laugh," Guy breathes, heavy. "I don't hear it enough." It's raw enough that Kakashi forgets himself, only for a moment but that's all it takes. He bucks without thinking and- fuck. There's no way Guy would have missed it, the way he goes still in just a fraction of a second is enough to make the dread begin coiling tight in his chest. Guy pulls back and he thinks this is it. He's let himself slip just for a moment and he's fucked up one of the few good friendships he doesn't deserve-
Guy flips him onto his stomach and drags him back and up by the hips, not even giving him a chance to catch his grip before he's redoubled his efforts, hands pushed back up his shirt and weight bearing down on his back, the unmistakable swell of him pressed against his ass. When Guy speaks he's quieter than he's ever been, the heat of his breath on his neck makes him harder than ever to ignore.
"My dearest rival," he echoes for the thousandth time "If I'd known I would have altered the nature of my prizes years ago, perhaps then you might have accepted more of my challenges."
Kakashi scrambles for the wherewithal to direct Guy towards lube, oil, something, assuming he intends to fuck him as he pulls back and tugs his pants and briefs down to his knees without any preamble. He manages to croak out something resembling the word 'lube' as Guy's hands settle hot over his skin to grip and spread him open. The nip to the swell of his ass, just at the top of his thigh, makes him shudder as he drops his head down onto folded arms and focuses on breathing through the reality of what's happening, not letting himself step away from the moment and into his mind. Each time his teeth sink into his skin, inching closer sends a sharp thrill of want lancing through his gut, keeping him grounded.
The heat of Guy's breath pushing a shiver directly up his spine, making his hair stand on end, is all the warning he gets before his tongue drags across him, hot and wet, all the way up to the knot of his spine as he reflexively curls his fists against the floor in response. He returns to prod and tease, no intention of breaching him just yet, only giving enough to drive the burning want in his chest for more. It's a sensation that always feels foreign. He's never quite been able to get used to it and having it be Guy, who has seen the best and worst of him, always chasing him down when he runs away, is what has Kakashi unable to pull his face out from his arms. Unable to face what's happening even more vulnerable than he already is. All traces of alcohol have been burned from his veins by the heat which runs through him at each point of contact. Strong hands holding him open, all of the places he can feel his legs brush against Guy as he squirms, and his mouth, his fucking mouth, as he presses his lips full over him and presses hard enough Kakashi feels himself begin to stretch open enough to let him in.
Just enough of a stretch to make him feel it, to make the muscles across his back, his abdomen go taught with the drive for more, then Guy pulls back to lick over him again. He repeats the process, stretching him, just a little further each time, thorough enough Kakashi feels the way his tongue gets thicker as he goes, before pulling back to soothe. It's not much, it shouldn't make him feel like he's ready to burst in the way that it does, but Guy is unendingly attentive and Kakashi's chest is on fire with the way each slow drag of his tongue. His shirt is pushed up around his shoulders and he feels overheated enough to wrestle it off, Guy shifts his grip enough to pull at him with a thumb and his palm slips across the tile as he struggles to shake off his sleeves so he can fling his shirt off somewhere across the floor.
A heavy hand comes down over his nape- he's pleased to note the damp palm, glad to feel some sign that this is getting to Guy half as much as it has him- and pushes him down carefully but firmly as Guy's thumb breaches him just enough to tug at his rim, make him feel the slightest ache from the stretch. There aren't many areas where Guy truly has him bested without question, but raw strength is one of them and while he's not pressing too hard, the reminder that he could, if he wanted, keep him pinned, is enough to have Kakashi letting himself slump toward the ground with a breathless groan.
Guy becomes relentless, playing and tugging at the rim of him with his thumb, tongue pushing in as far as it will go. He feels the hot, wet slide inside of him, pushing and prodding and writhing against his insides and shudders, pressing back against Guy's mouth. Teeth scrape just barely against the rim of him, where he's already feeling borderline oversensitive, and his cock twitches, heavy and swollen where it leaks down onto the floor. Each time Guy pulls back for breath he's panting and the distinct familiarity of it- he's heard it a thousand times, training, fighting, saving his life- it gets to him. Never allows him to forget who it is behind him, making him feel this way, forever wanting him near.
His thighs are shaking with the tension pulling his body tight and when Guy moans against him, so clearly lost in the task at hand and sending vibrations up his spine, it becomes too much. The noise which escapes him isn't one he's particularly proud of, his whole body clenches hard enough to border on painful as he bucks back against Guy's mouth and spills across the tiles, face and chest going hot with the flush of exertion. Collapsing to the floor in his own mess, he allows himself a minute to catch his breath, take stock of what's happened, what's changed, Guy's breath hot against the back of his thigh where he is, presumably, doing the same, before he heaves himself up against the burn of his arms and turns to push Guy onto his back. He refuses to fall, only going so far as to lean back against his hands so he can watch with an unimpeded view as Kakashi wrestles his pants and briefs down just enough, Guy lifting his hips to assist, and free his swollen cock.
It's as good as Kakashi never allowed himself to think it might be. Thick and dark and soft in his hand, burning the shape of itself into the skin of his palm like a brand. Kakashi pulls him off, savouring the weight of him, the way Guy's focus is on him with more intention than he's ever thought possible, refusing to let his eyes drop or allow Kakashi a moment to breath without burning for how much he feels wanted by him. He rests his other palm against the cut of Guy's stomach and takes in every jump, every shudder, every fraction of mounting tension as the muscles there go taut. It's the most silent he's ever been. Kakashi curses the fact that they never stopped long enough to end up grabbing the lube and spits onto Guy's cock to make do. Evidently, the visual of it does something for Guy because he brings a burning hand up to grip his nape and wind tight into the hair at the back of his head, forcing Kakashi to lean in closer as he works him.
"Does this mean I won?" Kakashi asks, somewhat nonsensically, he doesn't even remember the terms of Guy's challenge, anymore. Guy laughs, "Dearest rival, there has never been a day when my own prize was more clear." The words rumble through Guy's chest against Kakashi's palm, it's a feeling he only has a split second to appreciate before Guy is reaching up with his free hand to drag down his mask. He can't summon the will to stop him before he finds the taste of himself on Guy's lips. Kakashi tightens his grip and moans into his mouth and Guy pulls at his hair and drags him in close until they're sharing every breath between them. He can feel the way Guy shakes with the effort of holding himself back, making this last, and something about it makes him unbearably fond.
When he finally falls apart he pulls Kakashi close enough that he's barely able to keep moving his wrist and kisses him deep enough to steal the breath right from his lungs.
A/N: Why I thought my first fic in years should be a porny speed-write where I attempt to make the way Gai speaks seem sexy? Beyond me. I'm going to try to do one little piece each day this month, we'll see how successful I am.
