This is something I enjoy, with someone skilled and imaginative as my partner
1. I could be a lost traveller, who stops at a quiet farmhouse, unaware that the owner, once he sees me, plans to kidnap and enslave me, keeping me as his captive french maid or slavegirl, even his daughter. He could be wealthy enough to have my appearance altered, so that even if I escape, no one would believe me.
2. lost, I stop at the first building I see from the quiet road that I'm lost on, unaware that its a private BDSM resort. Perhaps afraid that I'll reveal its location, the person in charge drugs me and keeps me as the resorts newest captive slavegirl.
