Naruto, Sai/Sasuke, comparing fiction to the real thing
"Hmm," Sai says, leaning back a little further in Sasuke's hold. He just sits there, looking, long enough that eventually it makes Sasuke growl "What?", head turned aside awkwardly, fingers still buried in Sai's ass.
"It's much smaller than Konohamaru's version." Sai nods, seems to come to a conclusion. "Now I see why Naruto-kun likes you so much. The two of you match." He flashes his happy face up at sasuke, pleased to have figured it out.
Sasuke makes an incoherant choking noise, and tosses Sai roughly off his bed onto the floor before stalking out.
