Earlier tonight I was at a bar talking to a group of sorority girls, I happened to have had sex with 3 of their sisters and made out with about 3 more. Nothing crazy but I was talking to one of their sisters, a girl ive never met before, and trying to hook up with her. We were having a decent conversation when one of her stupid friends blurted out something like " oh ya well you've fucked so many of us." It was in a joking way but still it was fucking annoying because of the way her and her sisters reacted. What can I say in a situation like that? How can I recover from an accusation of having sex with several women?
