Emmanuelle near March
DAk, it is two things that create value:
total bill at the end: You went in with $100 in your pocket, how much of it was left when you came home
action potential: A girl who does $10 top $10 bottom BUT NO TOUCHING has limited potential, IMHO, to be anything more than eye candy ever. Part of the thrill of the game is getting further, more, or getting the girl to get just a little bit out of control.
A girl with a price for everything also has a defence for every move you have... so there is no mystery, just stacks of cash.
