The story I'm looking for is from the perspective of a sub, she somehow sells herself into slavery and is bought by a maddame of a brothel or club in the far east, she quickly learns that its not just a game anymore and she has to work, the threat of selling her organs if she doesnt work out is made at some point, i think she is used as a greeter in the reception too if i remember.
I thought i had a copy saved somewhere but i dont seem to be able to find it, i cant remember the title either.
