I came home early from a business trip, taking a late flight. As I pulled up to my house, I could see a flickering light from the bedroom window. I shut of the engine and coasted into the driveway with the lights off. Quietly, I made my way to the bedroom, not knowing what to expect. I walked in and saw my wife Barbara and her sister-in-law going at it. Karen, her sister-in-law, had a strap-on and was using it on my wife. I immediately joined in, pleasuring my wife. When we were finished, my wife said she was ashamed, but she and her sister-in-law had been sexually attracted to each other for some time and that it was the first time for them. Karen asked if I would do her next. I told Barbara that we had a new toy and I wasn't mad they were playing around.
