She wants to fuck you. She probably asked her blonde friend to go over to you first because she's shy to approach you directly. Common tactic.

Always assume the guy she's with is not fucking her.

In every situation, it's best to assume the best case scenario. It will put you in the right mindset for the approach.

Inner dialogue goes like this:
Why did she look over at me?
She wants the cock

Why did she give me her number?
She wants the cock

Why did she ask for my number?
She wants the cock

Who is that guy she came with?
Some chode who will pick up the tab while I give the girl the cock

And so on.

Hope this helps
