What was your craziest sexual experience?

For me, I was at a bar many years ago, I think I was 21, I didn't drive to the bar, but a girl wanted to give me a ride home, I still lived at my mom's house. She gave me a ride home, pulled into the driveway, right away she moved over to the passenger seat, on top of mem . She undid her pants, then mine, her movement was incredible. We got done, it was great, I never saw her again.
