Non of the characters belong to me nor does the cover. Underfell was created by Kaitogirl Underswap was created by Popcorn Pr1nce So this is obviously a under swap papyrus x Underfell sans if you don't like fontcest then why are you here? Sans yet again got a beating from his brother. This time leaving another crack, physically and mentally. Sans was tired of it. If he wasn't needed he'll just go and let someone else be his brother's toy. On that night he left for better or worse and ended up in underswap going through a portal left behind by either error or ink sans in search of a new universe. Warning* Swearing, blood.

You have lived in the underground for 4 months now, and had befriended the most adorable cinnamon roll ever, Sans. However, you couldn't help but to gain feelings for his brother, Papyrus, even if Papyrus pretty much hated you. Could you change his mind? Get him to fall in love with you? There was only one way to find out. Reader's gender is not specified! Also Papyrus doesn't smoke in this story, sorry if you wanted that! Credit to Dizplicity for the artwork! Please check them out, they're amazing! http://dizplicity.deviantart.com/

Just a heads up not the greatest at creating stories. Anyway you'll be a different reader each time but with a different Sans. I won't upload much but I'll try to upload as much as I can. Warning: there will be smut, kissing, maybe some sexual content, swearing, anything traumatic like abuse, and you being a hybrid reader like a Neko. Also none of the art is mine, all credit of art goes to the artists. So try and enjoy my terrible writing. 😄

Imagine Undertale, but Chara never showed up. Chara wasn't the first human in the Underground. What if a glitch occurred, and you fell down instead? You fell into the Underground, but you cant remember your previous life. Now, you are surrounded by strange monsters, who have also never seen a human before. Will they let you live? [written 2017]
