A young married woman takes her husband on a long and dangerous journey, leading him into a world of complete submission to her wishes. Sarah puts her husband into chastity and gradually feminises him, introducing him to the delights of cuckoldry and finally irreversible chemical castration.
This pretty much delivered as the book title indicated.
For me personally the story failed to draw me into the fantasy because it required too much suspension of disbelieve. It was a nice short hardcore sissification story and might be a fun read for those who want things taken too far, or are in need of a cautionary tale.
Perhaps this is the best story Kitty Williams has ever written. Although there are many issues with the story flow and build up, there is certain level of characterization that's entirely absent in other of her stories.
