Oh I remember an instance of this in a video me and an ex watched one evening that was kind of hot.
It was one of the Dirty Debutante movies (with that homely fellow Ed Powers).
He was with a young asian girl (obviously barely legal) and I remembering him being so into her, he kept wanting to get off with/on her, and did so I think at least 3 times (which is the only time I ever saw that guy cum more than once).
I vividly remember her being in the bathroom fixing herself up when they were done with the shoot, and he just attacks her and drags her back to bed for another round.
Maybe someone out there knows the movie..I saw it in about '98-99.
