For this one, I would be a college student perhaps, holidaying in Kiev or some other part of the Ukraine with a friend. Perhaps she talked me into coming over with her to ensure that I could be snatched and made to become a multimillionares captive, pampered girl, or a powerfull pimps newest girl. She could be in on it, or have no idea.
The one that works most is where Im taken and sold to a club, or a powerfull pimp, as he's after english speaking girls, and I would speak english. I would also be very beautiful.
I can add things if need be, but thats the basic idea.
