In this one, I would be new to the city, driving through and take a wrong turn. Stopped by you and a group of others, I would be robbed, and you would decide to keep me as your kept companion, your pleasure toy. Dressed in skimpy attire, or something themed, my appearance would be altered so that no one looking for me would recognize me. I would go with you, but never be able to escape, even during the day or night when I was out with you.
If this appeals to anyone, let me know.
