I had a dear friend of my mothers come over to stay the night many years ago. At one point she was showing my mother her new bra which had underwire, something new in those days. She saw me looking and smiled. Later that night I went past her bedroom and she called me over. I went in the room & she was in a black, lace girdle and black bra. She told me to undo my pants and take them down. I did and she had me lay on top of her and dry hump against her girdle. I did and had an orgasm in 2 minutes. Never happened again But I jerked off thinking of that night for years.
