My wife does not consider it cheating if I get a bj from another guy, but if it were a woman, she would cut my dick off. She has said that she would love to watch, not join in, just watch. She also added that she would like to see me returning the favor and sucking on a big cock. I know that because she likes me to suck on her strapon.
Have you done it, with her permission? While she watched?
