I was watched in two ocassions.
First, during a trip with college friends, we had rented a room and were 3 couples. The first day everyone made it covered by the sheets...but as the week advanced, we all were fucking and the girls riding on each boyfriend with no shame at all.
Second time occurred with my wife, but then we were still dating. We were ...... at her girl's house and by the very morning she woke up, grabbed my dick and started to ride me fiercely. Of course her friend and husband came to see and watched some.
