I love the idea. It might be even better if the guy(s) in the scene had a chance at bonus money if they got the whore to break early. It'd be like a little game. They start off with $1500 (or whatever amount) and it gets split depending on how long the whore can handle it. If she lasts 15 minutes, she gets the whole thing. If she lasts 5 minutes, she gets 1/3 of it and the guy gets the other 2/3.
