Work Text:
Haruka should be tired. Their room at the inn they’re staying at is warm, and the client paid for their meal tonight, which means for once, he’s pleasantly full. But he’s unexpectedly horny, and the urge isn’t going away.
He runs his hand across his stomach, considering his options. It’s too much effort to try and jerk off quietly enough to avoid waking Kantarou. Might as well bother him.
He doesn’t feel bad about it, as he slips into Kantarou’s futon and slides his arm around him to undo his yukata. Kantarou’s disturbed his sleep plenty of times like this in the morning, so it’s only fair.
Kantarou stirs awake as Haruka palms his belly. “M’tired, Haruka,” he faintly protests, but then moans as Haruka’s fingers press into his flesh.
“Tired, huh?”
“I-it’s just sensitive right now,” Kantarou says, all traces of sleep suddenly gone from his voice. “Because we just ate. That’s all.”
“Yeah. You really enjoyed that meal.” He runs his hand up towards the top of Kantarou’s belly, where it’s firmer and bloated from the heavy meal.
Kantarou inhales sharply. “Haruka,” he pleads, but doesn’t move to stop him.
“C’mon. I know you like being touched here.” He strokes his belly softly, up and down. “You always hold back, but I can tell.” It’s always a dead giveaway, the way Kantarou bites his lip like he’s trying to hold in a whimper anytime Haruka touches or bites his belly during sex.
“I…”
He pauses. “Are you embarrassed…?” Of all the things. Haruka’s done much weirder stuff to him than just petting his belly.
It’s too dark to see whether Kantarou is blushing, and too warm to tell if the heat radiating off his face is stronger than usual.
Kantarou doesn’t reply.
“Alright.” Haruka shifts closer so he’s flush against Kantarou’s back, erection pressing against Kantarou’s ass. “I like it too, okay?” The proximity makes him harder, and he grinds his hips against Kantarou, who moans a little in response.
“I like that you’re soft here,” he continues, moving his hand back down to the base of his belly. Kantarou’s soft everywhere, but he’s thickest around the middle, the skin there cushioned and pliable and bitable. “I like when we’re both all full and warm like this.”
Silence.
“And…” He sighs. “Okay. I like it when you eat a lot and get all tight and round like this.” He palms his upper belly again for emphasis.
“Do you, now?” Kantarou shifts beneath his arm, turning over so he’s facing Haruka. He presses in close til his belly squishes against Haruka’s. He’s smiling, obvious even in the dark, no trace of embarrassment on his face.
“You asshole. Were you just acting shy so I’d say all that crap?” His irritation isn’t enough to stop his dick from throbbing, though. He wishes he could tell if Kantarou is hard, but he’s angled so his belly is all Haruka can feel- and that just makes him harder, knowing Kantarou’s belly is jutting out further than his cock is.
“I don’t know what you mean,” Kantarou says, pushing him onto his back and straddling him.
“What happened to you being tired?”
“Mm, you’re right. Maybe I’ll just fall back to sleep here.” He shifts back a little to rest his head on Haruka’s chest.
Haruka makes an involuntary noise as Kantarou’s stomach presses down against his erection.
“And I’m too full and heavy to move, so I guess you’re stuck here.” Kantarou closes his eyes and nuzzles his head against Haruka’s chest a little.
He considers flipping them over so he can pin Kantarou down. But he doesn’t need to put that much effort in to show Kantarou he’s in charge. He doesn’t need to move at all.
He raises his knees and wraps his legs around Kantarou, thighs squeezing against the sides of his belly. Kantarou lets out a surprised whimper, and Haruka squeezes harder in return.
“Ah- fuck. I’m so full, Haruka, please…”
Haruka doesn’t let up. “I think I like you like this. Maybe I need to keep you stuffed like this all the time so you’ll be good for me.”
Kantarou moans loudly, and Haruka starts bucking up against him. He feels so good, hot and soft and sweaty and heavy on top of him.
“Just- mm- just keep you fat and spoiled and helpless for me-”
Kantarou gasps, and Haruka doesn’t need to feel his cock to know he’s cumming. His body goes limp, and Haruka takes the opportunity to wrap his arms around him. He throws the covers off them first to get some relief from the heat, then pulls Kantarou in close and ruts up against him.
Kantarou doesn’t protest or even move, just lies there panting as Haruka fucks his belly. Even stretched full like this, it’s still soft enough that their clothing is the only source of friction between them. Haruka clutches his hips tightly, claws digging into his flesh.
Kantarou will probably bitch tomorrow about the bruises and cuts he’s sure to be leaving on him, but he can deal with that tomorrow. He likes leaving marks on him, anyway, indisputable proof that, whatever the apparent nature of their relationship, it’s Kantarou who belongs to him.
He doesn’t let go as he cums, just keeps Kantarou pressed down against him while his trapped dick struggles to shoot off against Kantarou’s belly. Only when he’s finished does he let go, opens his eyes and runs his fingers up Kantarou’s back, claws returned to fingernails once more.
Kantarou’s watching him, eyes half-lidded in post-orgasmic bliss but still fixed on Haruka’s face. He always has liked watching Haruka get off.
“C’mere,” Haruka says. Kantarou shifts and scoots up, tucking his head into Haruka’s neck and inhaling deeply.
Haruka strokes his hair, but can’t resist tilting his head a little so he can bite at Kantarou’s ear. Kantarou is just incredibly bitable, is the thing, and he tastes salty from sweating. Like Haruka’s fucking seasoned him.
“Did…you mean those things you said earlier?” Kantarou asks quietly, voice muffled against Haruka’s neck.
Is he actually embarrassed after all, not looking Haruka in the eye? Or is he just too tired and blissed-out to bother lifting his head?
The answer is the same either way.
Haruka bites him again, teeth pressing in where his neck meets his jaw. “Look,” he says. “Let’s put it this way. If we ever somehow get rich, I’m gonna make sure you get really fat.”
“Fuck.” Kantarou lifts his head up, and Haruka can see how wide his eyes are.
He can also feel Kantarou’s cock twitch and start to harden against him.
“Again already?”
Kantarou squirms against him a little and looks at him pleadingly, with that damn, stupid, cute face of his.
“Alright, pervert.” He sinks his teeth back into Kantarou’s neck, hard this time.
