My experience has been that lots of these themes turn into hyper-violent free for alls or a lot of focus on crude places, heavy beatings or odes to penetration. Now, that's okay if that is the idea. Personally, I would like to play a female character in an international kidnap but I would go for more sensual parts and irony though.
If anyone else actually wants to work it that way. The effete side of nonconsensual, not nice as in fairytale capture stories but not so over the top pure nasty either and with lots of complex relationships?
Of course, it depends on how the whole story is set up, and how much this is a bunch of one on ones, how much a big round up and share around, etc.
