I did a pilot chapter for a series where everyone in the world gains animal traits and has to deal with said traits. Anyways, only process is near the end of the first chapter, the rest of the fic about how society and my main characters adapt to their changes. I was inspired by 'The Three Sisters' by MWE on Doc's lab, a hentai comic with the same concept (sorry, forgot the name and source), and a differen't anthro fic I did as a one-shot.
"Darwin's Backflips"

Anyways, read if you like stuff about TF's AFTER the changes. Oh yeah, it's a work in progress.
