A mustache ride, that is (albeit on an invisible mustache). We've heard all about this sort of thing from various and sundry classy tshirts, and from the looks of things in this gif, it seems like a pretty fun time.
Granted, the course of movement is a little more predictable than, say, the Coney Island Cyclone, but what it lacks in breakneck speed and whiplash, it more than makes up for in orgasmic thrills for the rider, and the joy of having a beautiful ass and pussy in the face for the very willing ride. Everyone wins!
