"(Y/N)! Stay horny..."

Welcome to my own lil twist on the Undertale x Male Reader section. This'll be like my FNF book, but with Undertale CHARActers. 

You've been chosen by a higher power of Monsterkind to warp in between AUs and fuck as many monsters as possible. Why? Because YOU will be the key to putting an end to the racism between humans and monsters....with lust!

[Disclaimer: All characters in this book are 18+ IN THIS BOOK, so don't be whiney bitch lmao, and all the art belongs to their rightful owners; be sure to follow them on whatever platform(s) they're on!]
