Warnings: Strange fetishes.
A/N: For the HAIR challenge at my beloved Copycock:'D (...Which is on LJ, for you silly FFnetters.)I had planned on making Kakashi the trichophile, but then I reread the challenge prompt, and "masturbating into a fistful of hair" just seemed so...juvenile. Sasuke-ish, if you will. So I ended up with this. I meant for it to be serious, but it kind of ended up as a bad excuse for smut. Ah well. They don't all turn out like you want them to, kids.

---

It’s gray. Soft gray, undertones of purple and silver. A beautiful color. It doesn’t look aged, it looks vibrant, like the sky before a thunderstorm.

God damn it.

Perfect. The perfect length and style, heavy bang falling over a stolen eye. Hiding it even more than a slanted headband already does.

Stop it.

And sleek. Shiny, healthy, not coarse like Naruto’s, not compulsively cared for and styled like Sakura’s. The way it falls, light, not weighted down, but yet thick--substantial.

Pervert.

He doesn’t know what it feels like. He’d like to. He can imagine it would be soft to the touch, but not silky. Like velvet.

Sasuke, perched on a tree branch, lets out a shaky sigh, fingernails tightening in the bark beneath him, tugging at the nails, hurting. He’s sitting in a tree outside Kakashi’s bathroom window and he can only barely see into the room, just a small strip visible. But it’s enough to know that Kakashi hasn’t returned home yet from going out to a bar with Gai, and he just has to keep on waiting. Because Kakashi takes a shower every night. He knows that. He knows, and he’ll just keep waiting.

And then. He feels it. Kakashi’s chakra signature, familiar but muted now that he’s not training or fighting, and Sasuke perks up a bit, feeling that chakra moving closer, closer, until Kakashi’s in sight, having stepped into the bathroom, vest and mask and headband already stripped off, dropped to the floor on his way to the bathroom. Sasuke doesn’t care about Kakashi’s face and he doesn’t care about seeing Kakashi naked, he cares about the way Kakashi’s hair drapes, slumping a bit tiredly, having been a full day since its last washing. It needs to be rejuvenated by warm water and steam and shampoo, and—and Sasuke realizes that his teeth are digging painfully into his lower lip and slowly lets the sensitive skin slide free.

Kakashi slides off his pants and Sasuke’s cheeks flush the slightest bit, trying not to watch too carefully. Not that he can even see much. But still. There comes the sound of flowing water pattering onto plastic shower walls, and Sasuke sighs as beautiful gray goes out of sight when Kakashi pads into the shower. More waiting.

He’s always waiting.

Sasuke allows his eyes to slide shut, concentrating on the simple in and out motion of breathing, and sees shiny gray hairs behind his eyelids. He snaps his eyes open as the water is shut off, the pattering of water being replaced by a slow drip, drip, drip.

Kakashi steps out of the shower, hair wet, dripping, beads of water rolling down his skin, and the color is different, darker, plastered to Kakashi’s skin. Sasuke has to hold back a quiet moan as Kakashi grabs a white towel and begins rubbing his hair with it, tousling and leaving it drier, as well as messed up, sticking up, but it still looks good, and Sasuke wants to bury his hand in the moist hair very badly, and his breaths are speeding a little. He lets out a small disappointed breath as Kakashi moves the towel on to drying off the rest of him. As Kakashi is running the white cloth over his stomach, he pauses, lifting his head and glancing about momentarily. As if he knows he’s being watched. But there’s no way that’s possible. Sasuke’s being careful to mask his chakra signature, and he’s just certain that he’s well enough hidden.

After a while Kakashi hangs up the towel and leaves the room. Sasuke slumps slightly, no longer so attentive. He’s watched Kakashi shower a total of three times over the last four weeks, and he’s always left disappointed. It’s good to watch Kakashi drying his hair, touching it, certainly more attention than Sasuke sees Kakashi pay to it during the day, but it’s never really enough.

Kakashi had been moving slightly more sluggishly than normal, the smallest hints of clumsiness in his movements, and Sasuke can’t help but wonder how much the man’s drank tonight. Sasuke waits pensively for a while, wondering. He should just go home, like the other three times. Go home and stroke himself sloppily to an equally sloppy finish like he does on so many nights now. Fantasies centering around that hair.

But yet—this is getting boring. He needs more, and he’s not just going to long for it any longer, he’s going to do something about it. There’s a fire escape outside Kakashi’s bedroom window. It’s easy enough for Sasuke to get around the side of the building and land on the metal platform, feet impacting quietly. Though he’s certain that Kakashi is at least mildly drunk, that doesn’t mean he’s going to be a reckless idiot. He has to be careful; he wouldn’t be able to stand it if he was caught.

This is his. This is private.

Kakashi’s window isn’t even locked, and Sasuke supposes that someone like Kakashi wouldn’t have to worry about that sort of thing. He slides the window open as quietly as he can manage, flinching anytime his cautious motions produce any sort of noise. Somewhere in the back of his mind, Sasuke realizes that this is reckless. Impulsive. He’s a fool.

But those thoughts trickle from his mind as he slips into a dim room, and spots Kakashi, lit by gentle moonlight, hair seeming to glow with its own ethereal light. Sasuke steps across the room, flinching at every footfall, until he’s standing by the top of Kakashi’s bed, his teacher’s head tossed to the side, hair spread alluringly. So close. Sasuke holds his breath, painfully aware of how dangerous this is.

It’s such a beautiful sight, though.

Still, he’s not stupid enough to try and touch Kakashi; even drunk, that would undoubtedly wake the man up. Sasuke is surprised Kakashi hasn’t startled awake yet. He is being as careful as possible, though—perhaps Sasuke is underestimating his own skills.

Sasuke has been hard since watching Kakashi dry his hair, and he glances pensively down at his waist, eyes widening slightly. No. He can’t. He shouldn’t. He’s just begging to be caught. Why is he being so impulsive and stupid? Doesn’t he have any self-control at all? It’s impossible to control himself, though, when his eyes are staring at hair highlighted by moonbeams.

Sasuke hastily pushes down the front of his shorts and boxers, just far enough to free his erection, in too much of a hurry to mind the rustle of fabric, seemingly so loud in such a silent room. Sasuke grips himself softly, and lets out a slightly shaky sigh. He needs to be quick, he needs to finish this and then never, ever do it again, stop pursuing this ridiculous addiction, and—he begins stroking himself hastily, roughly, hand moving with an adolescent inexperience, but it’s certainly enough. His eyes want to squeeze shut, but he forces them open, needing to keep on watching Kakashi’s hair. Watching, like he does every day, except this is definitely not everyday, and he needs something more, needs to elevate even further.

Sasuke startles, eyes wide, hand halting, as Kakashi lets out a low grunt, flopping over onto his other side, the back of his head towards Sasuke, close to the edge of the bed. Sasuke’s heart, which had already been pounding, is close to exploding now, but Kakashi doesn’t move anymore, and Sasuke supposes that Kakashi wasn’t awake, just his body shifting. His teeth clamp down on his lower lip, and he shuffles a tiny bit closer, hand going back to work.

That hair looks so good. It’s so close. So close, so close. Sasuke nudges forward the tiniest bit until—until. The tip of his cock just barely brushes against the hair on the back of Kakashi’s head, and Sasuke can’t help the tiniest choked moan to escape his throat. Oh God.

Soft. Mostly dry. Beautiful. Perfectly textured and cool to the touch and it feels. Good.

“Ahh—really now, don’t you think that’s taking it a bit far?” comes a low, vaguely amused voice, and Sasuke’s eyes widen, expression panicked, stumbling backwards except his shorts pushed down like they are impede this, and he ends up landing on his ass on Kakashi’s floor. Kakashi sits up slowly, expression tired, draping one arm on a raised knee. He doesn’t look angry, exactly, just irritated.

“I—I’m sorry, I’m really sorry, I wasn’t—I didn’t mean to—” Sasuke stammers out, more flustered than he’s ever been. Ever. Kakashi pinches the bridge of his nose, momentarily clenching his eyes tightly shut as if willing the entire situation away.

“Listen, you’ve really got to work on being less obvious, kid. All you do all day is stare at my hair. I would have to be blind not to notice it,” Kakashi says plainly, and Sasuke can’t bear to look at his face. Sasuke has no idea what to do now.

“At first it was cute,” Kakashi mumbles, voice thoughtful, “But now it’s just kind of creepy, yeah?” Sasuke gives a jerky nod. He’s not stupid enough to pretend that there’s not something extremely irregular to his—fascination with Kakashi’s hair.

“Listen,” Kakashi sighs, “If I let you finish, will you stop watching me shower? Because that is seriously annoying—and if you really thought you were good enough to escape my notice, you’re more of an idiot than I ever imagined.” Sasuke cringes. But wait, what in the world had Kakashi just said?

“F-finish?” he practically squeaks, unable to help his stammer.

“Yeah. Just get it out of your system or whatever,” and Kakashi’s voice is embarrassed, annoyed to have to talk about such things. Sasuke hardly think this is going to just go away, but he nods jerkily anyway. Kakashi can’t help his quiet snort at this. He’s never seen Sasuke like this, but he supposes everyone has some weird facet to them. It’s just more strange than usual, in this case, but somehow this fits with Sasuke.

“Can I—can you—” Sasuke trails off awkwardly, shifting uncomfortably.

He manages after a brief and painfully awkward silence, his voice quiet and hitching, “Put your head in my lap?” Kakashi drags his hand roughly through his hair—quickly letting it drop back down to the mattress as he catches sight of the way Sasuke’s eyes stare at this motion.

Finally, he gives a hesitant nod, and says in a pointedly flippant voice, “Yeah, sure, whatever.” Sasuke scrambles up to his feet, barely able to even believe this is anything more than a dream; the logical part of his mind is expecting to wake up soon with sticky sheets, while the tiny, childishly hopeful side of him that hasn’t been crushed just wants this to be real and wants for Kakashi to like him and doesn’t want to get it out of his system.

Annoyed by his clothes constantly getting in his way, he quickly strips out of his pants and boxers completely, only hesitating for a millisecond before his shirt is tugged over his head as well. Kakashi raises an eyebrow. Fuck, give this kid an inch and he takes a mile. Kakashi sighs, but decides it isn’t worth worrying himself with. He wants to get this over with and then he wants to sleep. He realizes in the back of his mind that he’s only doing this because this is Sasuke and he harbors strange feelings for the boy; any other person, and they’d have been dead the first time they tried to watch him shower. But that sort of thinking is far too complicated for his mind, addled by alcohol, and he quickly pushes it aside, watching as Sasuke climbs onto the bed, settling down behind Kakashi, legs Indian style.

With a very definite trepidation, Kakashi positions himself until he’s lying, head cradled in Sasuke’s lap. This is definitely the strangest thing Kakashi’s ever done, sex wise. He’s rather boring, really. He gets drunk occasionally and has sloppy fucks, one night stands, and that’s as far as it goes for him. Nothing interesting, and certainly nothing like this. He tries to stare at the ceiling, painfully aware that if he looked back a tiny bit farther he’d be met by Sasuke’s dick.

“Um, can I touch it?” Sasuke asks shakily, and Kakashi sighs, reminding himself that this is most definitely a one time thing. To allow Sasuke this bit of what he so desperately craves, and then let the boy move on. Right.

“I suppose,” he sighs, sliding his eyes shut. Sasuke reaches down with trembling hands, brushing them at first lightly through Kakashi’s hair, just needing to be sure it’s not going to suddenly disappear, before his fingers wind through Kakashi’s hair, stroking and tugging very lightly, playing with the strands. It feels sort of pleasant, a kind of affectionately playful touching that Kakashi hasn’t felt since—Yondaime.

“Oh fuck,” Sasuke chokes, and Kakashi can feel the violent shaking of Sasuke’s hands. He considers telling Sasuke not to curse, because, well, he’s Sasuke’s teacher when you get right down to it, but yet this has now gone so far beyond the bounds of a teacher/student relationship that he sees no point in even attempting to enforce his position.

Sasuke can’t believe how perfect Kakashi’s hair is. It feels exactly like he’d always imagined, and he hurriedly pulls his hands away, going back to his arousal which is desperately in need of attention. Kakashi can’t help the way he tenses slightly as he feels what is undoubtedly Sasuke’s erection on his hair, lightly at first, Sasuke gasping and holding himself back, but eventually he gives up on that and his dick nestles fully in Kakashi’s hair, Sasuke’s hand still stroking up and down, and it is really, really weird, even by Kakashi’s standards, and he’s been through some pretty fucked up things, but this is Sasuke, for fuck’s sake. And. Kakashi lets out a quiet sigh after a long moan from Sasuke. He wishes Sasuke wasn’t so vocal because this is starting to affect him strangely, cheeks just barely flushed, which Sasuke probably would have noticed, had he not been rather engrossed in what he was doing.

The way Sasuke’s hips push up against Kakashi’s head, softly, thighs shaking, is really a strange sensation, and Kakashi slides his eye shut, attempting to remain, or at least appear, calm until this is over with, which, judging by Sasuke’s jerky, desperate movements and gentle groans, should be soon. Ah, youth.

“Kakashi,” Sasuke sighs, fisting himself faster, harder, the back of his hand rubbing back and forth in Kakashi’s hair.

This is all rather confusing to Kakashi. Does Sasuke like him in the least, or is it all about the hair? He won’t mind if Sasuke is infatuated with him, because if he’s forced to admit it to himself, he has a creepy attraction to the boy himself, but if Sasuke is solely attached to him for his hair—well, Kakashi isn’t sure if he can carry on such a twisted (And kinky. Yes. Kakashi’s completely normal, if a bit lacking, love life, suddenly turned bizarre.) relationship. But wait, hadn’t this just been to let Sasuke get it out? Why is he suddenly thinking of any sort of future? Kakashi’s expression hardens slightly, beginning to look annoyed, and mainly with himself.

“U-uhm,” Sasuke gasps out, voice labored, “You alright? S-sorry, I’m almost done.” Kakashi chuckles, slipping his right eye open and glancing up at Sasuke.

“Thank you for the concern, Sasuke,” Kakashi starts, finding it bizarrely amusing that Sasuke took the effort to ask if he was okay in the midst of this—thing, “But I’m fine.”

“Ah! God! G-good, that’s good,” and Sasuke’s free hand clutches at Kakashi’s bangs, stroking the hair desperately with his fingers, tugging just a bit forcefully, but the pain is so mild compared to some of the pain he’s felt that Kakashi hardly cares about the clumsy, rough treatment.

“Nnm!” Sasuke moans, and with one last jerky, stuttering shove of his arousal into Kakashi’s hair, comes. Kakashi flinches at the feeling of moist stickiness spurting into his poor hair. Well, he should have seen that coming, all things considered, but he just hadn’t quite thought about it. Some of it is dripping down his forehead, tickling, and Kakashi raises his head, wiping his forehead clean—and wiping his hand clean on his sheets.

“Damn it Sasuke, that shit takes three freaking showers to come out of your hair all the way,” Kakashi mumbles, sitting up.

“I’m sorry,” Sasuke breathes, sounding drained and—depressed?

“It’s alright,” Kakashi sighs in response, turning to face Sasuke. And swallowing. Sasuke naked is a sight wouldn’t mind getting used to, no matter how much of a creepy pedophile it makes him feel like.

Shit. If anyone’s fucked up here it’s you, not him, you perverted old man.

“Listen, I—” Kakashi begins, before realizing that he has no clue where to go from there and trailing off. He realizes quickly that he has no God damn way to vocalize this, and instead settles for hastily bending down and smashing his lips passionately, if a bit clumsily, against Sasuke’s. Sasuke at first lets out some muffled, confused protests, but eventually he gives in to it and leans into the kiss, reaching up and entwining his hands in Kakashi’s hair of course, fingers brushing against sticky, tangled patches; it makes him feel vaguely guilty that he’s ruined something that he loves so much.

It’s his first kiss, asides from—but, well, Sasuke tries not to even think about that. It feels good, no matter how confused Sasuke is; he doesn’t know why Kakashi would ever want to kiss him, especially not after what Sasuke just did. After a while Kakashi pulls back, hazily glancing down at the small frame that had, at some point, practically fallen into his.

“Why would you do that?” Sasuke asks quietly, averting his eyes to the side. Kakashi ponders on this for a moment; though the kiss had seemed like a good idea at the time, of course he was going to have to come up with a way to explain it eventually.

“Well, I like you,” he responds simply enough, “That’s why I’ve been letting you get away with this strange shit, I hope you realize.” Sasuke blinks, hesitantly glancing up to meet Kakashi’s gaze. It hadn’t even really occurred to him until now just how much Kakashi has been allowing him, but as it begins to dawn on him, he can’t help the mild jolt of shock to go through him.

“I like you too,” Sasuke mumbles after an extended period of silence, “And not just for your hair, I—I think.”

“We’ll see,” Kakashi says, voice optimistic. He’s willing to wait until Sasuke figures it out.

He’s certain that he’s going to regret this in the morning when his hair is a tangled mess with hardened sections from the come that’s still moist now, still dripping slightly, but he really doesn’t feel like showering again tonight, and besides, he’ll have Sasuke to help sort it out. He flops down onto his pillow—the pillowcase can be washed too, he supposes.

“I expect you to be on time for training tomorrow, Sasuke,” Kakashi says with a mild grin, even though they both know that Kakashi himself will be late as always, “So you’d better get some sleep.” Sasuke hesitates, glancing at his clothes on the floor, wondering if he should leave, but Kakashi rolls his eyes, letting out an exasperated breath, and grabs Sasuke’s wrist, jerking the light boy down next to him. Sasuke is painfully tense at first, but eventually he relaxes, nuzzling against Kakashi’s chest, and Kakashi lets a hand entwine in Sasuke’s hair as they both drift asleep.
