Their parents didn't know they had traded house keys. His wouldn't mind much because the Nanjo already considered Kaoru one of their own, had been treating him as family since the two of them were still unable to tie their own shoes, but Kojiro had never been quite as loved by his best friend's mother. That was a whole thing and he'd never be in her good graces so long as they spent their weekend nights off skating together, being chased by the cops and breaking into rundown buildings for fun. Kojiro was fine with that.
What he wasn't fine with was Kaoru forgetting they'd made plans tonight. Not for the first time, he'd messaged the dipshit and got no reply, probably because his friend was deeply engrossed in a project and had lost track of time. For that same reason Kojiro had let himself in, trusting that ringing the doorbell wouldn't help when Kaoru was certainly wearing headphones, probably singing along while he wrote lines of code or poked electronics. Easier to just go straight up to his room, give him the appropriate amount of shit about being distracted and then drag him out to skate, as usual.
Except he didn't hear any singing when he walked into the big house through the front door. It was dead quiet downstairs, nobody home except Kaoru, and he was only sure of that because there was some dim light coming from his friend's window.
It wasn't as quiet by the time Kojiro reached the upstairs hallway.
What he was hearing... The sound was faint and he could almost swear it was all in his head, but he padded slowly towards Kaoru's room anyway, straining his ears. It sounded like... sighing. Grunting. His heart picked up and all of a sudden he felt like he was intruding on a private moment, because that sounded like porn. Either Kaoru had found more interesting company and forgotten about him (a name came to mind, and the thought tied his stomach into a knot) or he was having some solo fun, neither of which were his business.
He should leave. He should turn back now and make himself scarce before he made a noise or something and ruined everything. He shouldn't be imagining what was going on past Kaoru's cracked open door.
Gods, why couldn't he just stop being nosy and go home?
The answer was obvious. The stupid crush he'd been harboring for his best friend since, well, forever if he was being honest was the reason why he stepped closer instead. It wasn't curiosity so much as desire that made Kojiro very gingerly creep to the very edge of the threshold, his breathing sounding much too loud to his own ears.
Not that Kaoru would notice him. Now that he was within a few feet of whatever was happening in there, he could make more sense of what he was hearing. There was some TV show playing, though it was very low and distant, barely working as background noise. More importantly, Kojiro heard a much softer and whinier version of Kaoru through the door, one that wasn't concerned about how he sounded to everyone else, too lost in pleasure to care. The faint noises of him shifting around in bed painted such an alluring picture, too...
What if Kojiro peeked inside?
That was probably his stupidest idea to date. The odds of being caught were too high, and the consequences too dire. If he was wrong and there was someone else in there with Kaoru, he'd doubly regret it, because he really didn't want to see that. But he really wanted to see whatever was making his best friend moan so sweetly--
Kojiro's horny brain decided for him when he heard a gasp that made his dick twitch inside his pants. Fuck it, he needed to see, even if it was the single worst idea of his life.
It didn't feel like a bad idea once he took a deep breath and peeked into the room, though. In fact, his mind pretty much blanked completely and he forgot how to breathe for a moment, watching enraptured to a show not meant for him. His mouth went dry at the sight of Kaoru, leaning against his cozy pile of pillows and cushions, with one hand between his legs and the other moving over his chest underneath the sweater he was wearing.
Kojiro's damned sweater that he'd left here a couple of weeks ago.
His sweater getting soaked by Kaoru's sweat and probably getting even dirtier with what he was doing, fuck. The view wasn't as intense as it could be, but maybe that was a good thing for the sake of Kojiro's sanity. It was so much sexier to watch him from the side, how his arms flexed and moved, his feet shifting on the bed and his head falling back from time to time with another delicious little noise, just so he could raise it again as his body tensed from pleasure. Between the sweater covering his gorgeous body and his bent knee hiding the movement of his hands from Kojiro's hungry eyes, this was by far the hottest thing he had ever seen in his life.
It was like something tailor made to fit his wettest dreams. The flush on Kaoru's cheek, which he could only catch glimpses of at this angle, and the way his plush lips parted to let out these filthy, low noises that went straight to his dick. His growing need making him shift and change positions until Kojiro was sure he'd pushed a finger or two inside himself, holy fuck, his moans.
Could anyone really blame him for palming himself? He was so hard that his jeans had turned painfully tight, but he wasn't about to pull his cock out and-- Okay, maybe he was tempted to do it. How could he not be? Kaoru was so lost in touching himself that he hadn't noticed he had an audience, so what were the odds--
No, that would be taking things a step too far. And then he couldn't even give some dumb excuse about not wanting to interrupt if he did actually get caught. Plus... there was something about watching his best friend like this but not being able to see what he was doing, only infer it, that was doing it for him. It was so much dirtier than if he'd walked in a perfect view of Kaoru's pussy.
Fuck, he wanted to see that, too.
What kind of weird pervert was he that he felt this way about his best friend? They'd been attached at the hip since they were toddlers, had grown up together and kept very few secrets from each other, but this was...
Kojiro couldn't call it wrong even in his head, because he really cared about Kaoru. It wasn't just physical. He just also really wanted to fuck him into his bed until neither of them could move. And he was really enjoying this, too.
Especially with him wearing his fucking sweater and nothing else, creamy thighs in sharp contrast with the black fabric. Gods, he wanted those legs wrapped around his waist. He wanted to be the cause of those sighs and moans, and he wanted to leave a wide variety of marks on his skin. Bites, kisses, his fucking fingerprints on Kaoru's waist.
Palming himself wouldn't cut it.
"Fuck, Ko--" Kaoru mumbled loud enough for him to pick up over the faint, wet noises coming from between his legs.
Was that...? No, it couldn't be. He was hearing things, his brain filling in for what he wanted to hear while he was skulking in the shadows like a creep. It couldn't be what he thought it was. But then what? That didn't sound like Kaoru had noticed him there, his eyes firmly shut and his face turned away from the door.
Then he whined, loud and petulant like when they were alone and he could be the spoiled little princess that he was without judgment, only ten times filthier. "Please, Koji, ah--"
Holy fucking shit.
Kaoru was thinking about him while fingering himself. His stunning and wonderful and hot as fuck Kaoru, the siren that sang in his ear every time he tried to jerk off in the last couple of years, was having sexual fantasies about him. Fuck, Kaoru was moaning his name and he was there to see it, to catch it happening, purely by chance.
If Kojiro didn't do something about that in the very near future, he might just combust right where he stood. And the only thing holding him back was the knowledge that he shouldn't be there, that this was a gross invasion of privacy and a mistake and probably a very stupid fucking idea.
He stepped into the room anyway.
Kaoru noticed him when he was halfway across the room and panicked a little, yelping and jumping like he'd been burned. It lasted all of a second before he recognized who was barging into his bedroom and heading straight for him, then his breath caught and then he tried to say something. Whatever it was died on his lips and on Kojiro's, because he'd stopped thinking and simply climbed on the bed to kiss Kaoru.
Fuck, the noise he made against his lips.
His hands went first into long, silky pink hair, holding Kaoru as tenderly as he could in his painfully horny state. Then, as his princess melted into their kiss, they drifted down to his waist in order to fit their bodies together, pulling him closer. Kojiro needed him more than he'd ever needed anything else in his life, more than he needed air in his lungs, and he didn't waste any time in replacing Kaoru's fingers with his own.
"Fuck, you're soaked," he groaned, blindly tracing over his cunt because he couldn't tear his gaze away from Kaoru's if he wanted to.
"P-please," his princess gasped into his mouth in reply, shaky and flushed with a dazed look in his eyes. The reason why became clear a heartbeat later as he bucked into Kojiro's touch, unsubtly asking for more. "I'm so close--"
It was the easiest thing in the world to push a finger inside him, even with how deliciously tight he was. "Yeah? Does this help?" Kojiro asked, as if he couldn't feel his ensuing shudder where they were tangled together.
"Fuck, yea-- yes, Koji," Kaoru replied with a much more euphoric gasp, head falling back while pulling him closer by the nape of his neck, fingers tangling into his hair. And he looked infinitely more beautiful up close like this, mindlessly meeting the movement of his fingers, nearly riding them in his rush to get off.
By the time Kojiro got a third one in his pussy, he was frantically nearing the edge. Maybe it was a bit cruel of him to change the angle so he could watch, but it worked wonderfully.
Kaoru arched, clenching hard on him and digging his heels into Kojiro's back, tantalizing neck exposed and begging for him to bite it. So he did, coaxing louder and louder moans out of him, pushing him into overstimulation simply because it didn't seem to bother him. Gods, it was like Kaoru was drunk on the feeling and he couldn't get enough.
He felt fucking drunk, too. Or maybe he was dreaming and soon he'd wake up alone in his bed, painfully hard. Not that his dick wasn't throbbing already.
Then his best friend noticeably forced his eyes open and licked his lips. "Kojiro," he whined and smirked at the same time, somehow, making him really question that dream theory, "you dipshit."
"Excuse me?" he asked, chuckling in disbelief at the situation they were in and the nerve on this guy, to say that while taking his fingers like a pro. Because he hadn't stopped yet, only slowed down a bit, and he didn't plan on pulling them out until he was told to do so.
Instead of voicing any displeasure or telling him that it was too much, Kaoru bit his lip ring. There was a glint in his eyes that he knew damn well, the one that usually preceded major trouble. Next thing he knew, Kojiro was rolling with him as the little shit flipped their positions, the two of them moving with a bit of ease due to years of roughhousing. And just like that, Kaoru was on top of him, straddling his hips like that was his rightful place, smirking smugly at him despite the wonderful flush coloring his cheeks and neck and more.
Still wearing his damned sweater. Still not wearing anything else. Still soaking wet.
"You were watching me, weren't you?" he asked and it sounded like a rhetorical question, especially considering how he seemed more interested in asserting dominance by grabbing Kojiro's chin than letting him reply. Gods, fuck, was it even possible for him to get any harder? Because it sure as hell felt like it, his cock aching where the zipper of his jeans was being pressed into it by Kaoru's ass.
Fuck.
"Ever heard of knocking?" he asked, shifting to lean closer and brush their lips. "Were you planning on just pretending you didn't creep on me?"
"Kinda?" Kojiro admitted, finally getting with the program after his brain short circuited for the third time that night, maybe fourth? It didn't matter now that he remembered he could grab his best friend's lovely thighs and slide his hands up to his sinful waist. "I didn't think that far."
"Dumbass gorilla," Kaoru retorted, shaking his head with a fond smile on his face that made him feel like the luckiest man in the world, and sat up. "You're lucky I'm still horny as fuck," he sighed dramatically, but it lost any and all possible bite with the way he set about taking Kojiro's shirt off, then his undid his jeans. They worked together to get his pants down far enough that he could free his cock, and fuck if having his slender hand wrapped around it wasn't amazing. "Holy shit, Kojiro."
"Yeah," he managed, breath punched out of him by just a couple of strokes and the hungry look on Kaoru's face. Fuck, this was so much better than any of his fantasies, better than any dream could ever be. He'd never actually expected to be in this situation, to have this amazing view of his best teasing himself with his dick-- "Lemme see," Kojiro mumbled and it sounded a little bit like begging to his own ears, but he didn't fucking care, he was too busy pushing the hem of his sweater up with both hands so he could actually see.
"Perv," Kaoru chuckled airily, choosing that moment to angle his hips forward and give him the perfect view of him starting to sink down, taking his cock inch by inch. Of him being split open on his girth, of what made him gasp and whine loudly, of how perfectly they fit together. "Fuck, I'm-- gods, you're big, fucking shit."
"You're doing so good, babygirl," he replied without thinking, his brain catching up with his words a second too late, and he half expected Kaoru to be mad. If there was anything he hated more than being condescended to, Kojiro had yet to find it, but he really didn't mean it that way and... it didn't piss him off. It made Kaoru moan softly and clench around his cock, the half of it that was already buried in his pussy, and oh. "That's it, princess, you can do it," he risked, very gently helping him grind his way down, meeting him halfway and barely able to believe how good it felt. "You can take it, yeah--"
"Oh, gods, shut up or I'm--" Kaoru hissed, cutting himself off with a deep moan as he bottomed out. At some point he'd grabbed onto Kojiro's forearms for support and his grip was now turning painful, nails digging into his skin, but his face showed only ecstasy. "Fuck, I'm not-- not gonna last--"
"That's okay," Kojiro managed, completely breathless and awestruck. "We'll just... have another round later."
"Mhm, you cocky bastard," his best friend agreed, lips quirked in silent laughter like that was funny and like he wasn't clenching like a damned vice around him, and didn't give him an opportunity to answer. Any thoughts of saying anything evaporated from his mind once Kaoru began fucking himself on his cock, a slow grind that quickly turned into full on riding, both of them forgetting about the world outside of this bed.
There was no coming back from this. Kojiro would never be able to look at Kaoru like he didn't adore him, to hide just how much he loved him, and he hoped the feeling went both ways. This wasn't just sex for him, even if it was amazing sex that would leave him spoiled for life.
Judging by the way Kaoru kept calling his name in rapture while full of his cock, the odds were in his favor. "Koji, fuck," he let out, shifting again, and there was no way to tell whose idea it was, if it was him or Kojiro that needed to kiss so bad that they met halfway and collapsed back on the bed in a tangle of limbs. Kaoru whimpered through his climax and dragged him along, breaths mingled and foreheads pressed together, milking him for every drop of his cum and then some.
By the time Kojiro's head stopped spinning, he had an armful of a very melted Kaoru. His own body felt boneless and the sweet, lingering pleasure coursing through his veins couldn't compare to how happy the little smile on his friend's gorgeous lips made him. If nothing else, at least he'd always have this memory.
"I should kick you out for being gross," Kaoru mumbled without moving an inch, lazily nuzzling his jaw like a cat while laying on top of him. "After we shower, maybe."
"You're the one that was jerking off with my sweater on," Kojiro felt the need to point out, basking in his warmth and the fact that he was being playful about this whole thing rather than righteously furious.
"I didn't know the real deal was so much better," he countered with a huff, lips brushing the spot behind his ear and sending shivers through his body. Fucking hell, they had literally just had sex, how could he possibly want more? How could Kojiro say no to it? But then Kaoru seemed to remember reality and stiffened in his arms, squeezing him a bit. "It wasn't-- I wasn't just horny, y'know."
Thankfully a lifetime of being around him had taught Kojiro to read between the lines of what he said. And that was enough confirmation for now that they were on the same page. "I know, princess," he replied, pulling him up for a kiss, and the rest they could figure out later. "Wanna take that shower now?"
"In a minute," Kaoru replied into his mouth, apparently still very horny.
