Cumming on the face? Oh my God, what a HUGE turn on. The rest of the body, especially the belly, those things just happen. Cumming inside my wife is not always an option, and it has to go somewhere (not the sheets if possible). Cumming on the titties is also pretty exciting, but nary a time have I not fantasized about grabbing a handful of my wife's hair and pulling her head back while she's going down on me. The thought alone makes me cum so much harder. Whether I actually ever get to do it, that maybe another story.
