This story happened years ago when I was in college and was in a relationship with a girl named Mindy. Mindy and I were pretty serious, I was the first guy she had ever been with and she was my second. However she had an exhibitionist side to her and wasn’t shy. The first time we ever fooled around was in the back of my buddy’s van while he was driving.
You could call Mindy petite. She was 5’4” and weighed around 120 pounds. She had brown hair down to her shoulders. B cup breasts that just blew me away.
