A dick you have sex with but never see . You never get a picture , and you never have to give head .
Girl 1: how was your date with James???
Girl 2: it was great ! We hooked up but he slipped me that mystery dick . Where does it come from? Why can’t I see it ? And why do I not care ? I orgasmed 5 times
girl 1: ohh , that’s great sweetie !! I’m sure he’s not hiding anything. Men are shy about their penises. ( said unconvincingly ) Do you think you’ll take the mystery dick again?
Girl 2: mmm, I don’t know . Kind of weird . What if his cock looks like a baby’s arm with a hand ?? I can’t take that chance . I’m going to tell him I want to be friends and go on day dates, instead!!

When you're watching a guy+girl porno, and they're going at it, when suddenly another dick or even whole male appears on screen and it becomes a three way.
"I was watching a porno, and it musta been the camera man's mystery dick that appeared in the girl's mouth"
