"Fuck you," Genma said, after a moment's pause. He brought his hands up defensively, shoving at Kakashi's shoulders. The other man barely moved. Genma flinched back, but kept his hands raised.

"Fuck off, Kakashi. I'm not in the mood for this shit right now."

One grey eye pinned Genma, level with his own. Lips barely concealed by wet black fabric twitched scant centimeters away. In the year since they'd run that mission together, Kakashi had filled out, gained height. He was as tall as Genma now, and easily as strong.

And much, much too close. Genma could feel heat rising from the man's skin, smell sweat through the water. Feel chakra surging like heat lightning around both of them. His nostrils flared as saint elmo's fire played over his groin. Naked man, right on top of him, half-threatening, half demanding to be fucked...

"I said fuck the hell off!" Genma shoved hard.
