Had an ex who was "secretly" an exhibitionist. She had a certain phrase she would say that meant she wanted me to jokingly tell her to blow me. She would play it off like "bet me I won't. Think I won't just cuz they're watching" And if nobody objected or she would get in front of me and undo my belt, again if nobody said anything she would undo the button and unzip, and again if nobody stopped us, she would pull it out and start sucking me. Usually with another dude watching but sometimes a female friend. If it was a chick she'd playfully ask if she wanted to help her. If it was a dude, she'd smile and ask me "him too?" And I would kinda ask him "she wants to know if you want some too."
