I'd like to try a slightly different type of RP - probably short and - well, I won't say sweet....
One player is a customer, working online through a site where women can be purchased. There are variations in price and use - some of the women are willing, some of them are unwilling, some have specific skills, some are just disposable. All of this affects the price. The second player is a store keeper. The two negotiate need, price, and useage. Also, 'accessories'.
To start with, the store keeper might put up a picture:
What would the customer pay for this woman, and what would he/she like to do? The store keeper might make suggestions, and basically thry thrash out a scenario and a cost.
BTW - I'd quite like to be the customer!
