YCH Idea, need patreon thoughts (Patreon)

This thought on a YCH is a bit different.  Of a story where the main character is set.  (Still figuring starting point), but turns into a shemale rubber shark toy.  As part of their desire to be in a relationship.  ((They made a deal with a devil that will "Solve their problem")) the thing is...

The devil deal will take the person turn them into a toy put their dick/new dick into ever tightening chastity as they are turned into a good slutty toy.  And then as they are converted and and made into this toy, they are given the opportunity to lose the cage if they accept becoming a dominant toy devil shark, to take others.

The YCH would be the devil, those that top/pound this toy-to-be, those it will service, and later those it will take once it accepts/becomes a domineering devil toy top~

What I am looking for.  Starting species of a female or male of the turned into demonic rubber herm shark toy.

Positions for the YCH, demon obviously, but anything else for when I open it up on my FA journal?  Comment below your ideas, heart/fave suggestions you like.
