Futanari/shemale worldbuilding?

Story by lazy2277

I don't normally post outside of Futanarization, but this board has helped me in the past:

are there any stories that feature descriptive worldbuilding about futanari society/history?

Most of what I've found only includes a brief paragraph speaking about how that world/society came to be, before jumping to characters; are there any stories that involve detailed, non character-based descriptions of futanari society, history, social structures, biology, customs, etc.?

Thanks in advance
