This is only a short story but I hope you enjoy reading it.
She was 58 and I was 28. I had been planning for a couple of years to bring this event to fruition.
Her name was Eleanor and she was my wife's grandmother. She had lived with my wife and I since losing her husband in an industrial accident about 4 years ago.
Earlier in the week my wife had been called out of town on business and would be gone for a few days or even a week. As I had to work I naturally had to stay home, as did Eleanor.
When I came home the first night after my wife left, I headed for the shower to clean myself up and also to relieve some of my tensions while I was there.
I threw on my boxers and a robe and headed for the den where I decided to put on a video and masturbate while watching it. I was just settling in for a good session, watching this young guy banging away at an older woman. I was going at it at a pretty good rate, when suddenly Eleanor walked in and saw what I was doing. She didn't say a word and continued into the bathroom for her nightly ablutions.
I sat there stunned for a moment at what had just happened. I paused the video and walked into the bathroom after her. She was bending over the bath completely naked as she tested the water. It surprised me to find that she was still pretty well put together.
