I'm in my mid 60's and my wife in her mid 50's. I have been masturbating for as long as I can remember, but my wife had been raised in a very sheltered childhood and didn't really get onto it. We have been together now for about 6 years. Now with my encouragement she will masturbate but only when she is alone.
Last week we decided to get away for a short trip and do some shopping, we stayed in a motel over night and in the morning I woke up early as usual and turned on the TV with no sound as to not disturb her sleep. She was laying face down with her head turned away from me. I sat there stroking myself and not paying attention what was on the screen, and I noticed her moving around and her butt begin to slowly hump up and down. Knowing what she was doing really turned on , so I began to pump myself faster and harder , when my hand started making slapping sounds her humping became more visible then a few low moans came out and when she had her orgasm I almost came at same time. When she rolled over and I went over to her pussy was soaking wet. I moved over on top and we had incredible sex which didn't last long for either of us.
Now that we are back home I will try to get her to do it again but not buried under the covers so I will be able to watch her fingers doing there job.
