Please forgive **giant** wall of text I’ve never been good with formatting.
I loved to be watched when I masturbate just the fact someone is seeing me play with my dick turns me on so damn much that I sometimes don’t last that long with I masturbate. My wife is the same and when either of us are not in the mood or she is on her period we will be somewhere near them and just masturbate til we’ve cum and when I do she let me cum anywhere I want on her.
I travel a lot of my job and wouldn’t be home for weeks if not a month and because of this we made a agreement that as long as nothing physical happens (sex, blowjobs, handjobs, etc) we would allow someone to watch us masturbate when we’re not together and honestly it has made our sex life amazing. When I get home from trips we’ll tell each other about who watched us and what we did and on occasion share videos of said act and have had sex to them or watched each other masturbate to it.
