I would often hear " if your so horny why don't you just jerk off." Jerking off was for teens, so I took it to another level with toys, would self suck or anything that would try to get a rise out of her. She always enjoyed a good show and I always aimed to please.
Many things my cuckqueen bisexual wife have seen having sex with 40 different women. Even give them massage too.
I kneel on the bed naked and masturbate while she plays with my nipples. When I cum, I catch it all in my hand and eat it in front of her. (Sometimes she catches and feeds me!)
