What do you prefer? Good girls or bad girls?
It’s easy to differ good from bad just by spotting out where they bend:

Well, here we have a bad girl. A really bad girl :)
I think this the “good girl” is perfect for a nice bj and making the man feel more dominant. The “bad girl” works best if there’s another guy around – or at least a big mirror behind the woman. Need to talk to my girl-friend :)
