Having a fetish for a genital exam myself, the fact that she had her orgasm while I was "checking out" my scrotum made her orgasm even more interesting. She had clearly enjoyed the fact of watching me give myself an exam. Always the showman, I wasn't going to disappoint, so I went back and gave myself another in depth exam of my testes and scrotum, and then once again a hernia exam.
I was at this point so turned on at the fact of being spied on, being seen with an erection, being watched examining myself, and hearing her playing with herself right outside the door, that my throbbing erection would be denied no longer. I finally grabbed it and found it so incredibly erotic to be m**********g while someone was watching me. It is the most private and forbidden thing a guy can do to himself,
