Tortured is a Sans centered fan-fiction that takes place during a genocide route. It offers questions that are difficult to answer, such as 'How much bad is someone able to do before they become truly irredeemable?' This short story contains spoilers for the game Undertale and its genocide route, both of which I recommend checking out before indulging in this story. Trigger warnings include: mild language, blood, and intense and frightening situations.

This is based on the video game Undertale by Toby Fox. This may contain references and other things from the game that you won't get unless you've played it. Summary: What if Frisk never left the small town of Snowdin, and instead chose to stay with Sans and his brother Papyrus? P.s The amazing artwork I put in this story isn't my own.

(AU)Sanses×Reader! So many choices so little time!! Request are Open! I'm not the best writer so don't judge to much 'kay? Haha. How i write them is how i see that sans au would behave, don't like it then don't read it. don't assume what i write is 100% correct. Also keep your weird fetishes to yourself, i don't and didn't want to know. Stop being overly sexual/horny in normal chapters, i know sans is hot but stop screaming master or senpai, it ain't cute. Still updating as frequently as possible! :) ~Zane from 2020

You have a routine; jog, relax, and work. It may seem mundane to most, but for you it's comfortable, easy. It keeps you in your bubble. And you wouldn't change anything about it. That is, until two skeletons move in next door, and you discover that their lifestyle is a less than conventional one, but one you're going to have to learn to live with anyway, for better or for worse.
