[Bucky's fists are already curling into fists around the sheets at the first touch of those lips to him. (Okay, he might have to replace the sheet because he didn't think about the left hand being capable of ripping sheets, but his mind is nowhere near that).

God, it feels so amazing, makes him see stars even while he isn't coming. Fucking himself on Lupin's tongue feels like the most natural thing in the world, as if he were born to do it.

He loves the feel of Lupin kneading his ass, loves the rough contrast between it and the gentle...ish strokes of him against Bucky's rim.]

Please, pleasepleaseplease...so fuckin' hot... I don't even have to see you to know you - you, ah - look so pretty right now buried between my legs.

[It's the most he can get out coherently before he starts speaking Russian gibberish, growing erratic with his movements, with his impatience, stroking his own cock.]
