Stuck his finger up my butt

I was standing outside of a club last night with a guy who I had dated for a hot minute and hadn’t seen in 6 months and he agressively sticks his hands down my pants and starts to fuck my ass with his finger in front of everyone. Well, no one was really watching but it was titillating to be getting fucked with people around. But that’s just the voyerist in me. Later, he threw me all over the place while in bed but it wasn’t as much fun as finger in the butt in front of the club.
