Surprisingly, Yamapi comes before he does. Yamapi doesn't expect that, either, if the startled little gasp he makes says anything about it. It's all Jin can do not to moan when he feels Yamapi come on his hand, but he simply pushes harder, deeper, absorbing pleasure until he's too full of it, and he spills over the edge, too. He lies against Yamapi in a heap of sweat and skin, breathing heavily and basking in the afterglow they're sharing. Jin almost falls asleep like that, but the weight of a heavy comforter falling on top of him jolts him awake again.

"Please get dressed under there," Shige says, in a serene tone of voice that only comes with denial. He's pointedly not looking at them, and judging by the way Yamapi's quivering slightly, Jin knows he's trying not to laugh. "And next time, feel free to kick us out. Really. I insist."

Turning his head, Jin sees the others awake, too. Tegoshi is smiling sleepily at them like it's perfectly normal, Ryo seems torn between rolling his eyes and covering Tegoshi's, and Koyama seems to be more concerned with finding out where Massu went than the indecent state of the men on the couch. Jin has the decency to feel a little embarrassed, and he pulls the comforter over their heads, taking the opportunity to kiss Yamapi again.

"Hey," he mumbles, grinning slowly. "Wanna go for round two?"

"I heard that."

The only response Shige gets is a moan.
