[CaptiveSoul]

My mind also has cooked up endless scenarios for this sort of fantasy over the years. A few of mine:

- A vacationing couple's car breaks down on a lonely road somewhere out in the desert or deep in the mountains, with no cellphone signal, and they walk up to the wrong isolated house to get help. The perverts who live there seize the opportunity (and the unfortunate vacationers).

- A "Hostel" (as in the horror movies) type scenario, but more sexually oriented. Another happy couple travelling in Europe take a side trip to Braczveria or somewhere, and check into a quaint little hotel which is actually a victim-trap run by a secret international organization of sexual sadists. The drugs wear off, and the victims find themselves naked and locked in a cage in a dim holding-cell. They are taken and carried off to the sales floor, where they are chained up among dozens of other captives for the clients to examine and purchase (Special offer, loving couple, sold as matched pair only!). They are rudely inspected by many clients until the perp couple come along, find exactly what they are looking for, hand over the cash, and drag their new playthings away to one of the private chambers...

- Along the lines of one of the ideas in the "Couples forced together" thread: Our travelling couple is pulled over by a pair of corrupt cops in some backwater town. The cops learn that the couple haven't told anyone back home where they were going, and decide to have some fun. They arrest the couple on some transparently bogus charge and take them back to the station. Numerous and extreme civil rights violations ensue.
