My wife and I have enjoyed many sexual adventures, but this is going to be a new one. On Thursday night we are going to a nearby park. She will be wearing a sexy blouse, mini skirt and high heals, nothing underneath. We will go to the watch tower second floor where she will begin to give me one of her great blow jobs. While she is doing this a guy we know will quietly come up behind her and begin fucking her without her ever looking back to see who is there. She know it will be him, but will never check to make sure. We all think this will be quiet exciting and are looking forward to it. Anyone else out there find this exciting?
