I think this sounds like a fantastic idea and a lot of fun. are you looking for lots of seperate stories, or some way to link them together? For example is 'Sloth Island' going to be a community of kinksters, a holiday resort, a place where unknowing people get tempted in and led astray? Are you looking for an ongoing plot with a regular cast of characters or just lots of short fantasies?
I'm definately in and will help you any way you want, but I'm not sure I would be such an interesting character for you.
