Underfellgrillby Stories

Underfell is a dark and dangerous place filled with murder in violence, and Sans and Papyrus are the pinochle of it all. So nobody would ever suspect Sans to come back after a lost bet. Maybe you haven't seen all of what's under Red's mask, huh? Request for Icecream_Shipper

A bunch of Character X Reader oneshots and maybe a few two part stories of undertale, with all the undertale AUs. I'm Also adding preferences in now for some characters. Undertale, Underfell, Echotale, Swaptale, and etc, you can even request.
