I would be a tourist, making her way across the US on her own. After driving all day, I arrive in a city at night, and take some wrong turns, ending up in one of the bad neighborhoods. They would see me and kidnap me. The gang leader would be quite taken with me and decide to keep me, dressing me in cute schoolgirl outfits, cheerleader ones, and maid ones while I was out with him, and keep me in maid outfits and lingerie when I was alone with him in his home.
If this appeals to anyone, let me know. It can be set in any city, but the US and Canada are what Im visualising most for a location.
