They normally don't do this on the first time.
I mean...... That's just what I'm told....
This is why I say it depends. Chicks say that shit all the time. Sometimes they're telling the truth, most times they're lying. So it depends on what you find out after getting to know her on if she's easy or if she really doesn't give up the pussy fast. You won't only find out from the things she says, but also from being observant.
