The men’s onsen is empty, and for that Kinji is grateful.
He has enough reservations about this trip as it is; taking a bath in front of a bunch of naked strangers would have been enough to make him consider going back to America then and there. He hangs up his hat then follows Takaharu’s lead, pulling off shoes and stripping down until they’re both standing in nothing but underwear. Just two bros bathing together. Seriously.
“Catch!” Takaharu tosses Kinji a towel. Soon he’s shirked out of his boxers, completely exposing himself, before wrapping his own towel around his thin waist. “You put it on like this until you get in the water. Come on!”
The steam of the onsen makes it almost too difficult to see. Kinji slips a little on the wet floor, arms flailing while he struggles to regain his balance, as Takaharu leads the way to the edge of the spring. The water is swirling, bubbling, inviting. Kinji almost hates to spoil it.
“I ain’t too sure about this.” Kinji covers his eyes, turning around for good measure, as Takaharu lets his towel drop. It’s not until he hears a splash a moment later that he figures it’s safe to open them again.
“What’s up? I know you’re an assassin and all, but that doesn’t mean we can’t hang out.” Takaharu sinks further under the water until he’s covered up to his chest. He turns to shoot Kinji a wide, goofy smile. “Comin’, Star?”
“Beg pardon, but d’you think you could- you know-” Kinji grips his towel tightly with one hand and gestures vaguely with the other. “Look the other way? Just a minute?”
Takaharu blinks, confused, before understanding sinks in. He laughs even as he turns back around.
“Oiii, you don’t have to be shy,” he calls over his shoulder. “It’s not a big deal, seriously! Even Yakumo comes when we all go. So does Dad.”
“Well, people got different ways in America.”
Kinji dips a toe in the water to test the temperature. It’s hot, but pleasantly so. He folds the towel and lays it aside. After settling in beside Takaharu he’s glad he got talked into coming, after all.
He closes his eyes and slides deeper in the pool. The water feels cleansing already. It’s steamy and soothing and relaxing, even if one of his rivals is sitting just inches away.
“Now this is really hot,” Kinji hears Takaharu declare somewhere to his left. He snorts in laughter.
What had the young lady- Miss Fuuka- said when they’d first met? That he and Takaharu were similar? Kinji didn’t buy it, but Takaharu was certainly the opponent who gave him the most challenge, the most fun. Kinji was starting to like him. Takaharu seemed to like having Kinji around even outside of fighting, too.
“Not planning to catch me off guard, are ya?” Kinji flicks water at his opponent.
“No way!” Takaharu says. “It’s break time. And I told you, this onsen will boost your Nintality. You could really use it.”
“What the heck’s that supposed to mean?”
“Face it.” Takaharu slaps his back. “You just don’t have a chance of beating me for Last Ninja without help!”
Kinji shoves him back. “Why, you-“
Someone splashes water at the other, someone else yells the first insult, and that’s all it takes to start the war. There’s a lot of yelling and water traded back and forth through the steam; their shouts bounce off the walls and reverberate around the onsen. Kinji pulls Takaharu close by the shoulders while Takaharu tries to shove him away with an elbow. They’re both breathless from laughing and Kinji’s naked waist is slippery where Takaharu tries to grab ahold of him; Kinji loses his footing as he tries to stand and escape, and the sudden momentum sends them both toppling in the water with a hard crash.
For a long, horrible moment Kinji can’t breathe. The pool is shallow, he knows, but water is everywhere, in his nose, his ears, and clouding his sight when he frantically opens his eyes. He can’t tell up from down, and he’s still tangled with Takaharu, the other’s weight pinning him down. He thrashes loose and resurfaces with a gasp. The sight of Takaharu violently flailing around in the water makes him laugh again- he could get used to challenging these Igasakis! He coughs up water, aware that under different circumstances maybe he could have drowned, but still exhilarated, excited.
Maybe a little too excited, Kinji registers uncomfortably. Oh, great. Leave it to an unwanted hard-on to ruin a good time. He flounders back to the edge of the pool and hopes he can act like nothing’s going on.
Takaharu pulls himself back up seconds later, wet hair plastered across his forehead and face happily lit up in laughter like he didn’t almost kill them both. “See what I mean? You should be able to stop me, no problem.”
Takaharu paddles closer, sliding right up next to him. Kinji feels like his heart could very well hammer out of his chest.
“Uh-huh,” Kinji manages.
“Right?”
“If you say so.” Kinji’s voice breaks on the last syllable. He instinctively moves to cover his increasingly noticeable erection, regretting it as soon as he notices Takaharu following the motion- Takaharu’s eyes widen in momentary surprise before looking away.
There’s a very awkward pause. Takaharu coughs, crossing his arms across his chest as he settles against the edge, pointedly not staring.
Kinji nervously licks his lips. He shamefully sinks further under the water as he thinks of a way to explain himself. Sorry, young master, but they just don’t make guys like you back home?
While he's still thinking, Takaharu gently elbows him in the side. “Ah... guess I wasn’t the only one getting fired up, huh?”
“Oh- when you put it like that-“
It was a horrible joke. Even so, gratitude spreads through Kinji like a wave. He bites back a laugh, which makes Takaharu giggle, and then they’re both cracking up. Kinji laughs long and uncontrollably, still shaken and embarrassed, as Takaharu leans against him even more. He’s laughing too, throwing his head back on Kinji’s shoulder. After a few minutes they start winding down, but Takaharu stays where he is.
“So… we’re cool?” Takaharu lightly punches Kinji in the side.
“Don’t tell the others,” Kinji says. “About- about that. Me.”
“Sure,” Takaharu promises,“but they wouldn’t care, y’know.”
“’Lotta people would.”
Takaharu shifts against him, sitting up straighter. He suddenly turns and pecks a wet kiss against Kinji’s neck. Kinji tenses, unsure where this is going.
“I don’t,” Takaharu reassures him. A hand slips underwater and wraps around Kinji’s half-hard cock.
“Oh…” Kinji exhales. He's nervous- but a little aroused- as Takaharu slowly works his neck, eventually trailing up to lightly peck his jaw.
Takaharu moves to capture Kinji’s mouth with his own, teeth catching his bottom lip. He brings up a hand cup Kinji's face, pulling him closer, his other hand slowly pumps his cock all the while. Kinji starts, hesitant, then relaxes into the kiss.
Takaharu breaks away. “You’re, uh, you're cool with this?”
“Yeah.” Kinji says it in English for emphasis. He reaches up to thread a hand through Takaharu’s damp hair. “Yeah, go ahead.”
Takaharu pats the edge of the pool. “Up here,” he says.
Kinji heaves himself out of the water, feeling slightly less embarrassed than he did at the beginning of the afternoon. He sits; then he encourages Takaharu forward with a gentle pull on his hair. Takaharu lets go of Kinji’s cock to hold his thighs apart instead. He positions himself on his knees between Kinji’s legs and looks up at him with that goofy smile again. Kinji can’t help but smile back.
Undeterred, Takaharu takes hold of Kinji’s cock before pausing. He lets the tip of Kinji’s head rest in his mouth for a moment, brown eyes still gazing up. The way Takaharu starts to fondle his balls makes him bite his lip Kinji’s skin is sensitive to the air after the warm water; he shudders all over in anticipation and doesn’t know what to do with his other hand. He lets go of Takaharu and settles for gripping the edge of the onsen, so tight his knuckles are white.
Slowly, slowly Takaharu begins to swallow more of his cock, his mouth wet and warm and wonderful.
“Ah- ahhh-“
Takaharu pulls away again in an unpracticed movement. The catch of teeth along Kinji’s shaft makes him wince- so the guy isn’t as good at sex as he is at fighting, but that’s okay. At least he’s friendly. Hands slide up from Kinji’s twitching thighs to stop on either narrow hip instead. Fingers dig into his skin, nails sharp but at the same time pleasing. Takaharu swipes away the precome dripping from Kinji’s hard cock with a quick dart of his tongue. When he opens his mouth again he takes Kinji deep, as far as he can go.
"Taka- Takaharu-"
Now they’ve got a semblance of a rhythm going. Kinji leans forward, thrusting into Takaharu even farther before jerking back. Takaharu’s cheeks hollow with each noisy suck he gives. Kinji’s mouth parts and small noises of pleasure slip out. He watches Takaharu through half-lidded eyes as he sloppily bobs around his cock.
“We should be quick,” Kinji half speaks, half pants. He thrusts quicker, shallower, becoming aware that they're doing this in a public bath house and afraid of someone walking in on them.
Takaharu shrugs. This time his hands come to rest on top of Kinji’s, thumbs soothingly rubbing across knuckles. He mumbles something unintelligible around the cock in his mouth.
Kinji can feel the orgasm coming on before it hits. It starts somewhere with a warmth in his lower body and a tightening in his balls. It doesn’t take much longer- maybe the adrenaline of a near-death experience does that for you- and soon enough Kinji comes with a snap of the hips. He chokes down a yelp as he shoots into Takaharu’s mouth another time before the feeling subsides. Takaharu sputters, caught off guard, and he pulls away with come dripping down his chin.
“My apologies.” Kinji dips his head, mortified. “Probably shoulda warned you.”
“That was hot,” Takaharu grins, wiping across his mouth with the back of a hand. “Really!”
Kinji just stares at him- his rival on his knees, soaking wet with come on his face, and happy to be there. He was seriously starting to like this guy.
“Heh, I thought so, too. Thanks-”
"No problem." There's a glint in those brown eyes and Takaharu grips his hands tighter-
“Takaharu-?”
That grin has turned playful. With one quick motion Takaharu yanks Kinji back down back in the water on top of him. They land in a tangle of limbs and sharp elbows.
“Hey!”
Takaharu flips them over until he’s straddling Kinji’s hips. Kinji splutters in anger, barely able to keep his head above water. Takaharu laughs. “Number one ninja rule- never let your guard down!”
“Oh yeah?” Kinji shouts. He tries to shove Takaharu off but he’s pinned down good and tight. He continues to flounder anyways. “What was all of that about break time?!”
“I was totally messing with you, man.” Takaharu stands, still grinning. He reaches down to grasp Kinji and haul him up by the arm. “Gonna have to do better if you wanna be Last Ninja.”
Kinji shakes his hand away but now he’s laughing, too. He takes the towel Takaharu hands him. They step out of the pool and pause at the edge to dry off. “We really made a mess, huh?”
“Yeahhh.” Takaharu makes a face while they walk. “That’s why it’s better to come without Fuuka, she says I mess everything up. But the onsen’s supposed to be fun!”
“I reckon I could get used to your idea of ‘fun.’” Kinji smirks, knocking shoulders with Takaharu as they step into the dressing room. “Yeehaw.”
