...but Sissified.

Is a simple enough concept to play around with and half plan for, but in execution, it can prove to be more challenging. Sure, you can make Roland of Deschains a lot more like Calamity Jane with Double D's and if you think the movie was close, a BBC. Then what? Sissy gangbangs for an eternity. Sounds like a fun eternity for the sissy. Alright that's a branch. Here's an example.

This is the tale of how Peter Parker got bit by a Femboy Streamer who was exposed to radiation from an OsCorp Nuclear Reactor, and ...12 hours later.... How his Uncle Ben's mugging by a bimbo slut who really wanted some Uncle Ben dick caused Peter Parker to become Petra Parkinme, the Spectacular Cocksucking Sissy Slut Star.

Obviously this would be the point you pick your story, turn the main character into a sissy(or into a guy, then into a sissy, or however you want (un)tangle that knot) and spray the story with swimming pool of pheremones and see how long the line lasts before she/they/he (is satisfied).

I'm going to start with The New Testament...

The book of the generation of....Just kidding.
