I've been writing three different stories here on and off, but I've become burned out. Anyone wanna add chapters to any of them, I would probably approve. SPH, cuckold and shrinking dick are my favourite fetishes. My stories; https://chyoa.com/story/Dick.10736 https://chyoa.com/story/Jack-Strong's-Last-Stand.15572 https://chyoa.com/story/The-Mandingo-Society.7227
Which one is the cuckold one? I might be able to help. Also, I see that you've put one of your stories under "erotic couplings" - I'm a bit confused about what this category is. Do you have a definition for what it is and how it's different from other types of stories? Bit new here trying to get my head round the lingo.
I guess it's hard to tell what it was meant to be for in the beginning. Personally, I might say they are like romance stories without the "romance shit" or a series of erotic encounters. I think there are users who see it as a catch-all category for anything that doesn't fit anywhere else. With the next version, the category organization will most likely change. At the same time, I would like to offer definitions as (unenforced) recommendations for authors.
