Honestly, we don't think that Xtube user Big_Thingz_Poppin could find himself a better username if he got Ezra goddamn Pound to put together a brief, perfect description of what happens in this excellent clip.
Big things pop all over this video. There's our top's, like, mind-blowingly amazing butt while he pounds away. And there's also his huge dick during the extended facial scene that takes up the latter half of the clip. Then again, we might characterize that as more of a squirting sort of action. We can't be sure, though. We're not really much for poetry.
