My wife, Nancy, and I have always had a good sex life. We both manage to get off every time. I jack off quite often, mostly when I travel. Nancy always told me she does not masturbate as she is quite happy sexually.
One day I learned that I had to leave town as soon as I arrived at work, and consequently had to turn around and return home to pack.
When I entered the front door I called out but there was no answer, but I did hear the water running and knew that Nancy was running a bath or shower getting ready for work. I headed upstairs to the bedroom to start packing. Our bathroom is off the master bedroom and the door was not closed tightly so could hear the water running. I was about to stick my head in the door to tell Nancy I was home when I heard her moaning. I quietly pushed open the door to see what was going on. What I saw and heard surprised me. There was Nancy laying down in the bathtub with her legs spread apart and propped up against the wall while her hands held her vagina lips apart under the flow of water splashing on her clit. The shower curtain hid her face from view. Her moan was almost continuous and when she started to come, she let out a series of oh...oh...oh... that grew louder and louder as her ass wriggled back and forth.
I slowly tipped-toed out of the bedroom to preserve her self respect, but I had a huge erection. When I heard the water stop running, I slammed the front door again and hollered, 'Nancy, it's me. I got to go out of town today.'
She hollered back, 'I'm in the bathroom.'
When I got upstairs in the bedroom I started changing and purposely got down to the nude giving my cock a few strokes to make it hard again. She came out of the bathroom like nothing had happened. When she noticed my erection, she said, 'Not now, I'm late already!', not realizing I knew the reason she was running late.
I blurted out, 'I'm so horny I can't wait, so I'll just do myself,' and went into the bathroom and started jacking off standing over the toilet. Nancy came in to use the vanity and mirrors, but I just continued jacking. She didn't say anything, but stopped what she was doing when I told her I was coming. She came over and put her arm around me and watched over my shoulder as I shot my load.
It was almost a month later that I told her what I had seen that day and while she was embarrassed, we now tell each other when we want to masturbate and when we do. Intercourse is something we don't do much anymore, but we are both happy.
