Neighbor's Wife

I live on a lakeshore with neighbors who are weekenders. I saw their car leave and assumed both were gone. It was a bright sunny day so I decided to go out on the deck nude. I soon felt the urge to masturbate and started to stroke my penis. It didn't take long when I was ready to get-off, I shot a big load over the side of my deck and took my time cleaning up and went inside. In a short time the phone rang and it was my neighbor lady telling me what a great show I put on! All I could do was stammer "Thank You!"
