I fukken love furry episodes. The whole furry aesthetic hits me in the uncanny valley hard, but I love how insanely weird they get. Like, a normal fetish episode would be just a thing all about one of these weird fetishes, but furries just throw it all in like a horrific fetish casserole and all I can do is giggle at the surreal idea of this turning someone on.
Also for anyone who is confused at this being an entire rules system: I'm adjacent to the indie RPG scene and HOO BOY. Basically think of RPG systems and settings as fanfic for these people. And FAPP is their... well, I was going to say Omegaverse, but FAPP seems to be considerably more lighthearted and less tied to shitty gender roles, and I don't know much about other weird sex fanfic stuff.
The point is, it'd be more surprising if there weren't a complex weird sex furry RPG, because nerds are nerds.
