My wife and I have had sort of an on again off again sex life. It seems that when she's in the mood I'm too tired and visa/versa. I love watching women masterbate. Its probably the most sensuous sight in the world to me. Which brings me to my recent episode.
We both masterbate and will do it in bed while the other sleeps or pretends to!
One night I was very horny and needed some release while my wife was sleeping beside me. I put on a dvd of Nina Hartley's about masterbation. It starts out with Nina helping a young girl masterbate and showing the techniques. While I was watching this my wife suddenly stirred and rolled over into a position which I could see she was now able to see the TV. I waited before continuing my pleasure and the movie got to a scene where Nina was showing the girl how to stroke the clit by using the sides and shroud of the clit between two fingers. Moving it up and down almost like a guy jacking off! This got me to the point were I couldn't hold it anymore! I exploded with cum all over my stomach. I wiped off as quietly as I could and let the movie run for a few minutes but soon turned it off. Not long after that I noticed that my wife was squirming in bed very slightly, I'm sure to not let me know what she was doing. It's sort of our game where part of our excitement comes from the risk of getting caught.
I lay still while listening intently. She seemed to get a little more brazen and could hear her hand movement againt the covers. Then all of a sudden there was this loud sloshing sound! It was my wife trying out the new technique but she was so wet from the movie that when she moved her pussy lips up and down her wetness made a loud gushing sound. She, realizing that I most likely heard her, stopped. This got me so aroused that I had to move the covers off my then hard dick and jacked off in clear view of her. With my rythmic movements I also felt counter movement from my wifes side of the bed. I then came again so hard I grunted out loud. She too came and heaved her hips up then came to a rest. We both pretented not to notice each other and we never talk about masterbation either. It keeps it more exciting when its kept as taboo. This has been fodder for many a jack off session since.
