I'm not sure I understand the very end. What is Sesshomaru telling her she may do? What is she requesting? Perhaps that is explained in the story, but if you plan to post a one-shot drabble that is inspired by it, then I would suggest making such things very clear for the readers who haven't yet read your other works. It would just be helpful! :)
I thought you approached the sensitive subject of rape very poetically (NOT romantic... too often poetic and romance are used interchangeably, and that's not what I mean here) You weren't vulgar in the description of what was going on, but it was clear what was happening. I also appreciated the reality of the situation. It wasn't some romanticized even but rather to expressed the horror and evil of the act. Bravo!
