Summary
Bursting Birch is the name of my fantasy Boarding school that is plagued (Or Blessed) by a massive population of Futa students.
It's an open Prompt fic that I work on in my spare time, but I am kinda a slow writer. So if you've enjoyed any fics from that series and you wanted to ask anyone a question…here you go!
I wanted to make this a place to answer those without having to write a whole fic.

Veronica, or Vee, as she prefers, has always worked hard for the city of Los Diablos, helping keep the city running as the Mayor's Assistant. But years of hard work eventually start to wear down on a girl, to the point she has visions of a tall, intense blonde, watching her from afar...
Until one night, when she found out the blonde was no vision, and was instead a woman named Leslie LeBlanc. A woman who had been watching her for some time who knew just what Vee needed, and was happy to use her huge cock to deliver it.
