[Itachi has always been uncommonly fast, and his reflexes aren't primed for a battle right now; Kisame deciphers Itachi's intentions only a moment or two before they're carried out, too late to do anything but struggle or allow it--and Kisame doesn't much feel like struggling, even if he was rather enjoying being able to touch Itachi at his leisure.
His hand flexes in Itachi's grasp instead, fingers curling, wrist rolling to check the strength of the hold almost as an afterthought; he feels no need to struggle. No need even to apply any pressure against the pin; he trusts Itachi implicitly. There's no need to break free, even if he's confident he could. He chuckles instead, drinking in the heat and weight of his partner on top of him, the amused flicker of light in his eyes suggesting he might even be pleased with this turn of events. The hand that had been settled at his side reaches to slide up Itachi's thigh and cup him through his pants, before settling to lightly stroke his hip.]
Aaa, I guess you're right. But Itachi-san, everyone has to sleep sometime, don't they? Nobody can stay on-duty every hour of the day for their entire lives. Partners are there for each other so they can provide a little relief every now and then, right?
