There are 2 guys that came immediate to mind. Unfortunately, I don't know their names and can't find any pictures.
A few years ago I saw a preview of a gay porn film entitled "Movers and Shakers." In the preview, there's this young guy who practically begs to be fucked by an older guy. In the brief clip I saw, he seems like an eager, talented bottom. He also sneered (in a nasty, sexy way) when he smiled, and he sneer/smiled while getting fucked hard.
There's another guy who I only saw pics of, but he was an eager, cum-hungry cocksucker, with a similar sneer/smile. In the pics I saw of him, he was sucking off another guy through a chain-link fence, then eagerly licking up the cum.
