Half a scream muffled into Sam's mouth before Sasuke's clouded brain caught up to what had happened. When it did, he groaned right back against the other's moan, closing his mouth down just enough to participate in that kiss, tongue tangling with Sam's but more than content to let the other dominate his mouth. One of his hands lifted to tangle drunkenly in Sam's hair, holding him close; the other slipped just a little as he adjusted his hold, dragging nails roughly several inches across the other man's shoulder blade.

Conscious thought was almost completely lost in pleasure; he only had enough sense left to work himself into this coupling as hard and deeply as possible. One of his legs cocked its angle a little tighter around Sam's waist, over his hip, trying to coax Sam close enough for his belly to press a little more firmly with his thrusts against Sasuke's swollen, leaking cock, seeking out friction without having to pull his hands off the other man.
