I'm not sure if they explicitly disallow it in their ToS but what is the most likely is that either someone flagged the book or they added something to the algorithm that determines if the book is on the index.
Smashwords does allow non-con, so it might be worth considering. It's not Amazon in terms of size but people do go there particularly to buy erotica.
