Sasuke is surprised when he thinks about how long they've been doing this. Naruto doesn't make sense, this doesn't make sense, but since he turned fifteen his hormones have been taking over his actions more and more frequently, and secretly he's grateful that Naruto agreed to participate.

Naruto moves suddenly, tears his mouth away from Sasuke's and latches onto his neck and he can't help moaning. Fire travels along his veins and he worries momentarily that his system will be be damaged by the heat, but after a few more seconds he doesn't care.

When everything is over Naruto is sprawled across the bed, one hand tangled hopelessly in Sasuke's hair and the other tracing circles on Sasuke's stomach. His neck hurts, and when he pushes Naruto off him and gets up his legs shake, but he tries not to show how weak he feels as he stumbles into the bathroom.

He knows he doesn't have the energy for a shower, but after he's cleaned himself up a bit he feels a little better. He's not sure what to do now -- what was the etiquette after fighting turned into fucking? -- so he lingers in the bathroom, tracing over the marks on his neck with a finger.

"Are you done yet?" Naruto calls. In the mirror Sasuke can see that he's still sprawled comfortably, and for a moment he hates his teammate for not feeling awkward. Fuck, one year and three months and he's still not sure what to do after sex.

"What are you, a vampire?" he asks, moving his eyes back to the mirror above his sink. Naruto had attacked him particularly badly today; there are teeth marks in his skin, close to bleeding. Sasuke is glad his shirts all have high collars, or else people would ask questions, and he's not ready for that yet.

"Maybe I am." Naruto surprises him by sliding arms around his waist, but Sasuke manages not to jump. He's been spending too much time with his teammate. Nobody has been able to sneak up on him in years, and he doesn't know how to feel.

"Get off me," Sasuke says and closes his eyes, but he doesn't have the energy to back it up and Naruto ignores it, trailing warm fingertips along his stomach and up the centre of his chest. "Naruto-"

"Shut up," Naruto murmurs, nuzzling against his hair, and for once Sasuke obeys. He wonders whether it's worth trying to kick the blonde out, and realises that what they have has begun to mean something to him. That confuses him for a moment, and he raises his eyes to the image of the two of them, standing together in Sasuke's apartment. One blonde, one black. Contrasts.

He decides he doesn't really mind if Naruto stays.
