With typical hot babes, the end game is getting the guy to say "I love you" or getting him to demonstrate this love through a token of his affection like a diamond ring, a house, or a marriage proposal.
For guys on the other hand, the end game is usually about getting laid. As Ezo says, make her chase you until the very end if your goal is to keep her. Give in little by little and make her work hard for it. And don't ever give her that end game trophy that all women want. Don't be an easy kill.
I'm pretty sure you already know your PUA routines by heart. This is why I'm just expounding on Ezo's insight.
One more thing. In case you bang her, make her realize that she isn't going to get the same kind of quality bang anywhere EXCEPT from you. Very few women get to orgasm and most men can't even tell a fake one from a real one.
Just remember: for girls, the bang is not the end game.
