Remus moved his gaze over Snape's chest and arms. He looked good, very good.

He leaned forward and got Severus' trousers undone, sliding them down, his hands skimming down the other man's thighs. Remus leaned in a bit more and nuzzled his nose against Snape's chest, inhaling deeply and letting it out with a moan. He licked tentatively at a nipple as he moved his hands up, one going to stroke Snape's cock as the other went to cradle his balls gently.

He bit down a bit on Severus' nipple, moaning softly against his skin.
