I would love to tell her and show her. But I've learned over time that it makes her jealous. She wants all my cum for herself which is very nice of her except, I enjoy watching myself in the mirror as I stretch my hole and bounce on that big toy. Pinching that giant plug between my legs and try to hold it there till I cum. I used to be able to cum around it but now I watch it fall out followed by a great cum leaving me gaping and wanting more.So I don't tell her, even though I'd prefer if she watched and if she would copy my actions while I watched her that would be the ultimate.
Usually it is a situation where she walks in on me. Sometimes she will look in and smile and go about her business and other times if I am ready to cum, she will watch me reach orgasm and either go down on me and slurp it all up or let me finish and clean me up afterwards and feed it back to me.
I always wanked in private I never seen or knew it my wife has ever masturbated, she allows my alone time.
Don't go out of my way to tell her, but often she sees me doing it to something I'm watching on the computer or tv... Being caught can be a thrill, but discussing that is for another thread...
I love to watch my wife masturbate and usually when she does, I masturbate as well under my diapers and rubber pants. She gets off when she sees me sneak my hand under my soggy diapers and play with myself like a little boy. She calls me names, threatens to potty train me or spank me and gets herself more and more turned on until she climaxes. The great thing about women is they can go right back and do it again, and that's when I can keep one hand under my diapers and put my tongue on her pussy, lick her clit and help her get off again. Doesn't usually take long for both us the cum.
I've never told my wife that I masturbate on the side. Usually every morning, my wife gives me a 3 quart enema and strokes me through the first quart and a half. I will take over my own stroking until I finish. I love her to watch me take the enema and play with myself until I come. That is our routine. Right or wrong. We are both 75 years old and a bag of water gives me one hell of a boner. Go figure….
