My wife use to do this for me reluctantly. One time we were on a highway and I passed this truck with a young guy she liked. She took her shots and panties off and said " get along side of him" she masturbated in front of him to a tremendous orgasm. I almost came in my pants in disbelief. It was beautiful. I still jerkoff thinking about my wife, the mother of my children, showing this young man her hairy pussy and cumming for him.
