For this one, I would be backpacking through the US, Canada, or part of Europe. I would unknowingly stray onto land owned by a BDSM/Fetish club, one with members that live on the land. I would be seen by one of the members, who decides to lure me into his or her well equipped cabin or home, lace my drink with something, and keep me as their bdsm/fetish slavegirl, ponygirl and maid.
I could be collared immediately, kept in fetish heels, restraints, outfits, gagged and hooded when taken out and to one of the main meeting areas, where the other members would have no idea that I wasnt doing this by choice.
If this idea appeals to you, tell me your thoughts on how you see this one going.
