My wife and I came upon this by accident. I was doing her orally and I started to gently stroke myself at the same time. She found this soooo... hot. We were both surprised. Even hotter is to keep going till I orgasm. She is not very visual usually, but this she does like to actually watch. Anybody else into this ? Intimate and fun.
I prefer to focus on her orgasm until she has cum, then she likes to watch me relase all that pent up sexual tension while she watches
