Sometime during anal sex, the male pulls out and draws the infinity sign with his dirty member around her funbags.
Girl 1: We took a big step last night, I asked him to give me a dirty infinity. It hurts when I sit down but at least I know our love goes on forever.
Girl 2: I thought I smelled something funny on your shirt...and I'd be lying if I wasn't a little jealous.
