My little sister had asked me to drop some dinner left overs off at her father-in laws house as he is now divorced and lives alone. I had always thought of Archie as being a handsome man, he was in his early forties, and was very active with golf and tennis. I knew he didn't date much now as his divorce had cost him a small fortune. I usually saw him at birthday parties and during the Holiday Season at my sister's house.
When I arrived, I knew Archie was home as both of his cars were parked in his driveway back by his swimming pool. As I rounded the corner at the back of his house I stopped dead in my tracks, as Archie was laying nude on a floating raft in his pool. He was sporting a nice erection and every now and then he would give it a few loving strokes with his right hand, not very rapid strokes. The strokes were, I think, just enough to keep up his erection. I stood behind a shrub for over five minutes watching him do this to himself. All the time becoming hornier and hornier, and at the same time wondering how I was going to get out of there without him noticing me.
This went on for about thirty minutes and then Archie began to really jerk himself off and he soon shot a big release of sperm onto his chest. After he came, he just laid there on the raft for another five minutes or so.
I now thought I would try and sneak out of there as I was afraid that Archie would get out of the pool and discover me. I was successful and made it back to my car. I opened my car door and honked the horn several times and slammed my car door really hard hoping that Archie would hear me in the driveway at the front of his house.
I was right, he did hear me, as Archie appeared in the driveway wearing shorts and a T-shirt. I just smiled at him and told him that I was dropping off his dinner from my sister's house.
Of course I acted as nothing had happened and soon left Archie's.
I made it to my apartment in a hurry and rubbed a good one off.
The whole time I was thinking of what I had just witnessed and had a fabulous orgasm courtesy of Archie and my little sister. I think I would like to get to know Archie a little better in the future as I am a single woman and now think of Archie in a different manner.
