Disgusting... It was the only word you could use to describe the world and the people inhabiting it. Ever since you lost the only person who truly mattered to you in your sorry excuse of a life, you hated the world and everyone and everything in it. But maybe it can be better. But maybe it won't. Especially when your father (one of the kings of the mafia) tries to sell you off like some bargaining chip in his back pocket to a pair of skeletons. The worlds gone to hell and all they can think about is wealth and who will inherit what. At least your not going to just lay down and take it like they want you to do. But what do you do when one of them is so damn persistent? WARNING!!!! ⚠ MATURE CONTENT LIKE SMUT, NUDITY, AND TORTURE IN THIS FIC!!!! RATED MATURE FOR A REASON!!! This is also a Reader insert by the way. Spelling and grammatical mistakes may occur and I apologize for that. I do try to go back and fix them when I spot them but I may have accidentally looked over some. ('⌒`;)

👉🏻Aren't you ready for a different one?👈🏻 Where Sans isn't attracted to you from the very beginning? Where he wants nothing to do with you? ~~~~~~~~ ~~~~~~~~ You are 20 years old, living alone, and you love exploring. Searching for beautiful places to admire nature and to escape reality. You miss your companion in exploring since childhood, Frisk, who has recently gone missing. Wondering where Frisk could be, and worrying about their safety, you still explore, hoping to find them. Then you are reminded of the old fairytale legend. The race of monsters that ruled the surface alongside humans. None of that could possibly be real. Could it? ~~~~~~~~ ~~~~~~~~ Warning: Strong language in some chapters Have fun picking apart every single emotional, protective layer Sans has, dear reader! ;p Rankings: #1 in "nonbinaryfrisk" out of 10 on October 14, 2022 #1 in "sansxreader" out of 1,500+ on September 18, 2023!🥳 #2 in "toriel" out of 1,000+ on February 27, 2023 #1 in "grillby" out of 1,000+ on May 28, 2023 #12 in "undertale" out of 1,500+ on June 20, 2023 #4 in "frisk" out of 1,000+ on December 6, 2023 #5 in "asgore" out of 1,000+ on July 26, 2023 #1 in "xreader" out of 1,000+ on August 7, 2023!😱 #2 in "alphys" out of 1,000+ on August 11, 2023 #5 in "sans" out of 1,000+ on August 17, 2023 #6 in "undyne" out of 1,000+ on August 17, 2023 #1 in "soulsex" out of 14 on December 6, 2023 #6 in "papyrus" out of 1,500+ on December 6, 2023 #1 in "undynexalphys" out of 110 on June 7, 2024 #1 in "alphysxundyne" out of 81 on June 7, 2024 #2 in "alphyne" out of 301 on June 11, 2024 #1 in "papyrusxmettaton" out of 98 on June 7, 2024 #1 in "mettatonxpapyrus" out of 60 on June 7, 2024 #1 in "papyton" out of 549 on June 11, 2024 I DO NOT OWN UNDERTALE OR ANY OF ITS CHARACTERS.

Moved from AO3 because of reasons! "You are the only maid (or worker in general) that serves for the Skeletal Household. It's a skele-ton of work, but you manage by keeping onto a fairytale dream."

Nightmare found a young child a long time ago. When they fell into a coma it sent him over the edge. several hundred years later the child wakes up in a castle of darkness, surrounded by people, er... skeletons, that they don't know. Now they are being raised by murderers, cannibals, and world destroyers. Oh yeah! And their Uncle is the god of Death. Fun. WARNING (but not really): This story has been known to give people heart attacks and possible death from wholesome cuteness. I am not responsible for said medical emergencies or deaths. Read at your own risk. ~~~~~~ || Few things. 1) The first couple of chapters are going to basically just be Nightmare, but it's for plot reasons. 2) Dream is definitely going to be a little ooc. Don't like it, don't read. This is just for fun. 3) Like I said, this is just for fun. So, updates are when I feel like it. 4) I'mma try to keep the pronouns for (Y/N) gender neutral, but I may just drop that at some point. Depends mostly on what you guys prefer. 5) any art or videos added are not my own unless explicitly stated. Cool? Great. Let's get started.

He killed them all. Dust, down the waters of the the forest it runs, through the veins of the skeletons and the demons that prowl the night. It's the silent enemy, the adversary that slowly chokes and brings down entire armies to their knees. None can oppose it for none have the will or the strength. And it is the dust that emerges from the mouth of a mountain that overlooks a city, the dust that creeps and crawls through the forest and down the alleyways. It is the dust that wraps its bony hands around the throats of the damned ignorant enough to walk the streets, squeezing until the last heartbeat thrums. You are a detective in this city, a quaint area with little crime and a police force hopped up on Dunkin Donuts. But when a string of murders plagues the town, you are thrown on the case following cold leads and an ominous trail of dust. But one night, when you catch wind of a scream and follow it through the dark, you find a skeleton and the rest is history.
