Correct. JohnCBB, the author of the Literotica story, was also originally the writer on this project. Life forced him to step away after Chapter 4, but it was never his intent that this kinetic novel slavishly follow the original story. There were elements that were in the original story that he now says "meh" over, and others about which he wanted to go into more depth.
He and I worked out a general theme and set of principles for FF&S early on, and I've been trying to stay reasonably close to that out of respect for him. (I send him each release - he's said he's happy with it.) It's also been an writing interesting challenge, as the protagonists don't act in ways I would personally.
Thank you - I'm glad you're enjoying. As I've stated before, I fully understand that this content isn't for everyone, and I have no intent of diluting it by trying to make it so. It is what it is.
