Used have a SO that could cum if a breeze blew up her skirt. Used to piss me off, she would have about 8 a day and I busting my ass to pop one off. Even worse she was always going for an AVN award so I couldn't tell if I was giving her one of her 8 daily allowance or she was in rehearsal. LOL. Oh well, guess it's my ego, but it's always better for me if I think I have something to do with it.
For the record, I have never faked a money shot. lol
