Summary
You died.
Plain and simple, one moment you were there, strapped to the table in that ever so dark laboratory. Then a loud cracking had occurred - the sound of your own soul giving up. It had been deafening, like ice breaking beneath your feet. That purple crystalline heart shattering like fragile glass, unable to persist any longer.
The testing had been too much for you, not even you could persevere through it. Not after months—years.
You…died?
Then why were you here? More importantly where? What had
Gasterdone? And why did reality seem to glitch in and out with every painful thrum from where yoursoulshould be? And who were these skeletons that felt oddly familiar to yoursoul.>> Persevere?

Summary
Falling into the Underground wasn’t on your to-do list. Falling for two skeletons definitely wasn’t either.
Blue is sunshine bottled in bone—sweet, loud, and determined to make you smile even if it kills him. Rus is quiet, steady, and the kind of person who remembers your favorite tea. Between the two of them, you’re constantly flustered, overfed, and very, very loved.
When both brothers realize they’ve fallen for you, chaos ensues—except it’s the polite, apologetic kind of chaos where no one wants to hurt anyone else. What starts as a tangle of awkward affection becomes something honest and warm: a relationship built on trust, laughter, and a whole lot of skeleton hugs.
“WE CAN SHARE THEM!” Blue insists, bright as ever.
Rus sighs. “That’s not how dating works, bro.” -

Gonna try my hand at this for the first time! These will all be Sans/ Reader, but might play around with various AU's I don't normally mess with.
Might also sneak some canon or not canon scenes in here from my fics if they fit hehehe.
Also going to try to do some of these with Gender Neutral readers, which I am not very good at but gonna get some practice in! GN Reader will stand for Gender Neutral reader.

Summary
After your father's business failed, you were forced to move to another country to start a new life and avoid being skinned alive by the collectors.
Well, maybe now you can finally chase your dream of becoming an opera singer!
The only thing that sucks is that you’re now married to a strange man (you’re really hoping he isn’t old...) and there’s this weird aura or feeling calling you from the catacombs beneath Ebott’s Opera House.
Wait… is that a skeleton!? -

Summary
You'd never expected to be one of those people who bonded with a random stray, and if you did, you never expected it to turn out like this. The tiny... blob of an animal was cute, affectionate, and melted your heart before you'd even named him. Unfortunately, not everything is as it seems. You've met this lovely creature before, and he definitely remembers you...

Summary
Months after being on the run, I was finally found and made to stay with a mage. Unfortunately for me, the mage I was stuck with was more evil witch than mage. Not only that, but he's caused the many skeletons that lived on his property to dislike me, too.
As grim as it was, I could manage. At least it was better than death.One month into my stay, however, something changed. Another skeleton appears, one much different than the pairs that the other ten came in. The mage demands that this skeleton be roomed with me in the attic. The attic where all the rest of the forgotten things go.
The rest of the skeletons argue and attempt to find compromise. During all of this, though, this new skeleton meets me.
And he refuses to leave me alone. -

Summary
With the ascension of monsters, there hasn't been a boring day since. Living in a town close to the mountain range had its perks, and things certainly changed when the neighbourhood I lived in starts getting new residents.
The only problem now is finding a better job.
Luckily, a skeleton appears and tells me about a restaurant I can work at. I accept.
And I soon run into a whole bunch of other skeletons that all seem to like me.
Romantically, and I'm afraid of what will happen. -

Summary
Finding yourself in a whole different multiverse wasn't exactly how you were planning your week to go, but knowing you, it was bound to happen at some point.
But hey! It's not all that bad.. well except for Dreamtale being in utter chaos, not having the squad with you, and being 'kidnapped' a couple times. But then again, this multiverse was already proving to be much better than your previous one. Or at least, there is more opportunities here. And come on, how could you miss the chance to see this many stars?!
Now you just needed to figure out how to get the squad here, hopefully without the stupid chicken.
Nightmare has a bad feeling, your Nightmare. You'll just have to make sure he doesn't go insane with worry.

He knew that you wanted him, and that your seemingly innocent teasing was an attempt to take charge, to take his control away from him.
His sharp gaze told you that he wasn't going to let that happen so easily.

Summary
You're an engineer who works for Ebott's best research facility in one of the labs; your lifelong dream after finding a journal on Mount Ebott when you were a kid. When you aren't in the lab being smart, you're gathering materials at the abandoned doll factory for the machine you're trying to build.
But one night, you meet a skeleton at the factory. Naturally, you lie about why you're there and say you're there to hunt ghosts. You befriend him and try to find a way to gather the materials while keeping up with that lie. But those lies catch up to you when you start to meet all the other skeletons.
Edit: As of Chapter 29, all chapters have been edited and fixed slightly!

Summary
“YOU LOST IT?!”. Were the three words that echoed through the throne room, shaking the large ebony pillars that lined the walls. “WHAT DO YOU MEAN YOU LOST IT?!” “Well if Cross ha-”. “I don't care who’s fault it was, this was the easiest mission I have EVER tasked you three with!” A heavy grunt escapes Nightmare as he sinks into his seat. Pinching his nasal ridge. His tentacles dripped and swayed furiously. “Cross, seeing as you were the one leading this mission, do you care to explain what happened?”
Cross steps forward and bows down before the big throne. “Well, uhm, you see…”
