Feminized for his Inheritance 4: The Director's Cut
I had written the book to end after the third volume, but Laurie, who commissioned it, wanted a bigger ending. After writing another 4,000 words for her, I decided that we should just add another couple of thousand words and make it a 4th part of the series. This part has a lot of sex and some training and really does give the story the bigger ending it deserved. If you liked the first three parts, you're going to want to read FF4: The Director's Cut.
