When my wife and I were first married we were at my parents house for the weekend. My parents were out of town and we were using their bedroom to have sex. My brother came home with a friend and they were watching from the hall. My wife told me they were there and I moved so that she was more visible under me. She then said she wanted on top. They watched until I came. When I got up and pulled on my shorts they were gone. Later I talked with my brother and he said that was the hottest thing he had ever seen.
