I got this idea from looking thorugh a book of Michael Manning art. It would probaly be extreme or NC-Bon.
This idea would have me playing a male cop (or p.i.). He isn't particualry muscle bound or anything. He is set on the trail of a prostitue/drug/human traficking ring (the details can be worked out) and is captured by the leader of this ring. The leader (they can be male, female or herm. Doesn't matter) decide to teach this cop a lesson. They decide to not only break the cop until he is sbuservient to their wishes but to transform him into a she male who will work to bring them in money.
There are some details that can be hammered out of course. Anyone interested could just post here, or message me.
