If you really want something cool, then you can tell the story from the different point of views of the persons involved, I mean you would start off by narrating from the point of view of the man who sold her the car, then retell the same story form the point of view of Martinm the hair dresser, then one of the guys on the saofa nad of course hers.

This will allow you to examine and satisfy the fantasies of people imagining themselves to be the clumsy stylist (Martin), the voyeur who ultimately gets involved in the action (guy(s) on sofa), the one who take advantage (Car seller), and of course the sub.

And to answer PCs question, it doesn't matter (at least to me) whether she's a hooker or not as long as it doesn't show, I mean she has to look innocent enough, with the proper hair quality, nice face (not that hookerish face we all know) and she has to act totally innocent and doesn't start enjoying her self and looking at the camera and smiling like a fool as the action progresses.

Cheers.
