I LOVE THIS STORY! But fitting in with it being NC-17, could you include sex scenes instead of just "cutting away"? It would make sense. I personally know no fic that ever needed NC-17 unless it included highly detailed rape or well detailed sex. If this is just a violent/language fic, it can be R as well.
Well, each chapter will be rated per its individual contents. Yes, so far the highest rating it needed was R but some future chapters will contain exactly what you describe and require the NC-17 rating. I am glad you are enjoying it though. BJH
