-description, a female friend of mine (my best buddies sister) flirts with me, we talk about our sex lives, deatils etc, she lets me touch her anus when I wanted to explain something about anal sex than I try to go for kiss and she turns, puts a smile and says I don't know, come onn and stuff like that... wtf?!

Btw she is fucking some dude but he is not her boyfiend but she says he does not make her cum.

Is she typical-female insane or just batshit insane, btw she is a small time criminal and cannot hold a job or even report for social services on time.
