$400 is cool! Even prostitutes make less. So the girl didn't miss out. And her boyfriend was good. He'd make a good businessman. Because they usually share chicks for free with their friends. But the important thing was that the project would work now. Although I would go on with the business. I could get the bitch to do other people's business. There's a demand.
The stepsister is seductive enough - so why not show her off to a friend? Now everyone will know she's a classy bitch and he'll be jealous!
