Chapter 1: Slow Burn

Notes: So I hope you guys will enjoy this series! I'm currently writing another Undertale fic that you can find the first two chapters on somewhere (shameless advertisement), and the skeleton bros are gonna play a big part in it and so I decided I wanted to practice writing with them a bit. What better way to practice then to make fan service? Sorry it's a female reader and not male or neutral (odd since I love to rp and write as guys), I just want this to be as easy as possible for me to write because I'm a loser who shies away from a challenge. I'm not use to writing this way so this is already a bit of a challenge, hahaha...ha...Also can you tell I'm posting this from Archive of Our Own?

(See the end of the chapter for more notes.)

Chapter Text

Eyes opening fast and wide, you find yourself staring at the familiar ceiling of the inn in Snowdin. Where was Snowdin? Why under the forbidden mountain in the land of monsters of course. It never dawned on you in your entire life that maybe you would one day end up living under a mountain with monsters. You had originally been climbing the mountain with your boyfriend, escaping the horrors of college, but…

Deciding to wipe away those thoughts before they took a turn, you get up, stretch those aching bones, and then get changed into your favorite outfit. You didn't have that many outfits to be honest, just enough for three days. Still thankful for falling down here with your trusty bag that held your clothes and several other personal items, you grab said trusty bag and stuff it with variables of all kinds. Since you've been staying here the fact that often your awesome bag was needed for the weird situations you got in could not be overlooked. Then just like that you left your room and walked down the stairs, waving casually to the rabbit monsters who owned the inn as you made your way outside.

Taking a deep breath you notice how the weather was cold as usual, so maybe it had been a bad idea to go outside without realizing what you were going to do today. Normally you visited with friends, helping them out with their daily problems and just having fun in general. Sometimes you guys got serious and worked together on trying to find a way out of here. Thankfully the queen returned and, alongside the king, was assisting in restoring hope. It was what they all needed right now. You had been offered to stay at the castle, however, the idea just didn't settle with you. It just didn't feel right, so for the current time you lived in an inn so you wouldn't be in anyone's way. Yep, living the sweet life. Also…there were two skeletons that just seemed to make your day here in this area.

Smiling as you realized what you were going to do today, you hurry on your way to the home of your two favorite skeleton boys. They were brothers, and they felt like they were your brothers to be specific. Who knew who was the oldest of the three of you, not that it really mattered, though sometimes you admit to finding yourself thinking about if you were hanging out with creatures that are older than your great great great grandparents. You haven't known them that long but they really did feel like they were family.

Arriving in front of their house, you raise your fist, preparing to muster up a polite persona, when suddenly the door opens up, almost knocking you in the face but thankfully you stepped back in time. You weren't the only one surprised; it seems the skeleton who opened up the door was surprised to see you as well. "HUMAN." He exclaimed in that special voice that only could belong to Papyrus. There he stood, tall and thin with his, er, interesting costume. At first it slightly weirded you out, but now you just found his fashion sense to be adorable and full of innocence you envied.

A bit taken aback by his sudden appearance, you gave an unsure smile before waving your fingers of the hand that had been in a fist at him in a silly matter as a form of greeting. He seemed pleased and before you knew it, he was posing in a dashing fashion. "I THE GREAT PAPYRUS. HAD NOT BEEN EXPECTING YOU TO APPEAR SO EASILY. THAT JUST GOES TO SHOW HOW EFFICIENT I AM." He said, or more like yelled. But yelling was how Papyrus communicated. Sometimes you wonder if he got that from Undyne. Puzzled, you were about to ask him not for the first time, what the hell was up. Before you could, Papyrus turned around and called out, "SANS. I ALREADY RETRIEVED THE HUMAN. THAT WAS EASY!" He said with his usual goofy look. Now you were really confused. Had Papyrus meant to get you? Usually it was you who sought the skeletons out. Not to brag or anything, but often it was you who fit the role as leader of your group of monster friends and decided who you would spend your day with. Sans was usually your adviser.

Speaking of Sans, the shorter and thicker skeleton walked slowly into view, wearing his usual wide grin of teeth. "nice going bro." He complimented his brother, expression never changing. If you were to describe Sans in one word…well you wouldn't be able to. He was a monster full of mysteries. Sometimes you got nosy and tried to learn more about him but then somehow you would always just get pranked between time and space. You still couldn't figure out how he could always appear, disappear, or rapidly change something in the environment in the blink of an eye. You eventually learned just to take it all in and not ask questions. Way less of a headache.

Getting control of the situation, you finally found your voice. "Do you two need me for something?" Your question was firm, learning early on that these two could be trouble, but your voice was also filled with a curiosity that danced on your tongue. Sans eyed you, knowing all too well how the gears worked in your mind it seemed. He didn't answer though, letting Papyrus take the reign. "YES WE NEED YOUR ASSISTANCE." And just like that, Papyrus ran back into the house as elegant as a gazelle. Looking at Sans, you raised an eyebrow. He merely shrugged and started walking back inside calling without looking back, "lets talk inside. It's too cold out there for my old bones." You nodded and made your way into the nice cozy house, the age question back in your head.

As you sat in the kitchen, Papyrus made no waste of time to set down one of his emergency dishes of spaghetti that he stashed throughout the house in front of you. That was usually a sign that something big was about to happen. These two now had your full attention. Playing unconsciously with the food by using your fork that accompanied it, you eyed the two sitting across, warily, noticing that Papyrus looked excited about something while Sans just looked…normal as can be. For once, Sans started to talk first, meaning that he was trying to make sure this would go smoothly as possible. "so we've been thinkin' about it and-" He was suddenly cut off by Papyrus who stood up, and outstretched his arms, knocking the poor chair down. He then yelled, "HUMAN. WE HAVE DECIDED WE ARE GOING TO RECONSTRUCT THE HOUSE SO YOU CAN LIVE HERE!"

Notes: You made it to the end, congrats! Thank you for reading. If this goes well with good reception maybe I'll try to upload the next chapter this week, maybe tomorrow even. Sorry for the terrible writing, hopefully it will get better. My style kind of has a slow pace that picks up then goes slow and picks up again. Or so I've been told. We'll see now won't we? Anyways, have a lovely day or night! Also I write stories for money so yeah -hint-
