Both are cool, but this:

This is where you are going wrong. By the middle bit, she should already know you like her and she should like you. That should be there at the subtext level definitely, but almost all the time it should also be there at the verbal level - i.e. it should be damn near obvious that you like her and she likes you. In a sexual way.
By this point there should be no beating around the bush son. Don't let her think for a second that you want to be friends. Whether you are following indirect game or direct game, one way or another you both like each other by this point. You want to fuck her and she knows it. When you've put that on the table (in whatever way you've expressed that) and she is still standing talking to you, all you need to do to pull is not fuck up and say something dumb. Build comfort, spend time with her, and she'll want to hook up.
