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!)
When I am in the mood and she isn't if I need it bad enough, then I grab my vibrating cockring and anal plug combo add another slightly smaller cock ring at the base just in front of the other, and I hand the remote to my wife. She plays with the settings for both the anal vibration and the plenum area. She just watches me moan and start slowly jerking off as slowly as I can take it. She just grins and watches me while I take care of myself. Then I clean up and we go to sleep. Couples aren't always on the same page sexually, but it is nice to know that you can still work together even during those times.
My wife has watched me jerk off, masturbate with dildos and has watched me give and receive bjs and more. She has always been a voyeur.
