Underfell Sans x Skeleton Reader

First meeting

It was a beautifull day outside and you were walking in the forest, watching the nature. You came to the forest often because you could relaxe here, you knew your way around. Suddenly you heared yelling and decided to check it out. It was coming from that post outside of the forest, you've never really cared about it since there was usually no one there. You got closer, the yelling grew louder. You went to the edge of the forest and hid between the plants. You peeked through the leaves and saw two Skeletons. You were surprised that other Skeletons existed, on the other hand you knew you lived pretty isolated and far away from any town so of course you didn't know a lot about the people living in the underground. You took a better look at the Skeletons. A taller one who was wearing a ripped red scarf, a ripped black t-shirt, ripped black pants with a red belt and red boots. The other one was smaller. He was wearing a jacket with furr, black shorts, sneakers and a red pullover. The taller one was yelling at the small one who was just standing there enduring it all. You felt pitty for the him. You got closer and overheared a part of there conversation. The small one was called Sans. You thought that name sounded pretty cute. You got even closer, you could see them both clearly now. Both had red pupils inside their eye sockets. You took a closer look at Sans. You thought that he was kind of adorabel. The taller Skeleton gave him a slap along with calling him trashbag and some other names. Sans fell onto the floor and the other one left the scene while mumbeling a few insults. You felt even more pitty for Sans and you wanted to make sure he was okay. You left the bushes. You were wondering why you were doing this and if you should turn back. Too late! He noticed you. You walked up to him. He was still on the ground. You felt awkward so you kneeled down next to him.

At first there was an awkward silence between the two of you, wich you decided to break. "Are you okay?" you asked quietly. He didn't answer, instead he was just staring at you with his red eyes. You couldn't help but think of how insanely innocent he looked with that face he was making. You shook it of and wanted to help him. You felt like you had to explain so you said, "I saw what that Skeleton did to you, and i wanted to make sure you're okay". He still didn't answer. "May i have a look?" He hesitated for a moment before tilting his head a little, showing the place he was hurt. He kept following your every move. It was scratched and red. "That looks bad. Wait i'll help you with that!" You grabed his hand. He was startled at first and tensed up at your touch, but soon relaxed a small bit when he noticed that you were using healing magic. "Who are you?" he asked with a rough voice. "I'm sorry i forgot to introduce myself. My name is y/n." He touched his skull at the place where his injury used to be. "Good job with the healing. I'm Sans by the way. " You smiled. He stood up and offered you a hand, "Ya plan on stayin' down there?" You grabbed his hand and he pulled you up. "Thank you" He looked at you, "Don't think i've ever seen you around, ya new here?" You were not sure what to answer so you nodded. "Want me to show ya around a little?" You nodded again. "Silent type, are we? Oh well, follow me" You were walking along next to Sans for a while, there was silence until he asked: "What were ya doin' in the forest anyway?" You replied: " I was walking, it's really relaxing, until i heard yelling and i wanted to find out what was going on." Sans chuckled: "Boss sure can get loud sometimes." "So he's your boss?" His smile died down: "No, he's my bro." You realised it's best not to force this topic. When you turned your head back to the way you saw a big sign saying "Welcome to Snowdin". You chuckled. "What's so funny?" You quikly answered: " Nothing, it's just that i like puns." He looked at the sign and put on a big smile, revealing two rows of gleaming white teeth and one golden tooth. "If you like puns then I have a skele-ton of them." You chuckled. For the rest of the way he keeped making puns and you keeped laughing. You passed a building wich had two doors one on the far right and the other on the far left. Above the left one was a sign with the word "SHOP" in blood red paint. Above the right door was a sign with the word "INN" in the exact same color. The windows were covered by curtains so you couldn't see what was going on inside. You came to a place with the name "Grilby's". Sans turned towards the building and stopped at the entrance. You were a little confused on why he had stopped until he said: "This is my favourite place. .....ehm.....soooo.....Wanna eat somethin'?" You smiled and answered: " I would accept but i don't have any money with me." "It's okay i'll put it on my tab, come on." He offered you his hand, you hesitated but accepted his invitation and grabbed his hand. He led you inside rigth to the counter, you both sat down next to each other. A purple flame monster came towards you. He had a pair of glasses and a black bartender apron on. Sans greeted him: "Hey, Grillbs'" The monster answered with a simple, "Hey" He noticed and looked at you smirking: " Who's your little Girlfriend over here Sans?" Once his words met your brain you felt your face turn as hot as an erupting volcano, you knew that your face was covered with deep (f/c) blush. You covered your face with your hands to hide your terrible blush. You felt the most awkward in years. You glanced at Sans only to find his cheekbones covered in a slight red blush. He was scratching his neck awkwardly while stuttering, "S-she's new 'round here and i-i'm only showing her around." The flame monster looked at us with a huge grin and a Yeah-sure-face and asked what we wanted. You finally managed to calm your blush enough to face Sans and asked him to order for you. He smiled faintly and ordered two burgers and a bottle of mustard. Until the food arrived you stayed silent and thought about what Grillby said: Girlfriend. You allowed your mind to drift a little but caught yourself staring at Sans and thinking how sweet he was. You felt your face start to heat up again so you quickly shook of that thought. You got startled when the food was set down infront of you. It was a normal burger with nothing too special or fancy but it still looked good and tasty. It had been a while since you had eaten a burger so you took a bite, as expected it was really tasty wich caused you to smile. You looked over at Sans only to see him drinking the mustard straight from the bottle. You didn't know what to think about that. You must have been staring because he pulled you back to reality saying: "What?" So you asked him: "What are you drinking?" He chuckled and asked wether you wanted to try some. You nodded because you just didn't believe that he was drinking mustard. "It had to be something else! It had to be!" you thought to yourself. He handed you the yellow bottle, you lifted it to your mouth and took a sip. When the thick liquid entered your mouth you ripped the bottle away from your mouth. That was definetly mustard. It took a lot of your strength to not spit it out onto the counter. Instead you swallowed it almost causing you to gag. You usually didn't mind mustard but only if it was on food like fries or something like that. But not on itself! The taste made you shake in disgust. Sans had started patting your back gently: "Easy there. You good?" You shot up and silently snapped at him with disbelieve in your voice: "HOW CAN YOU DRINK MUSTARD!? MUSTARD?! I JUST.. HOW!?" You must have looked pretty dumb because he started to laugh lightly. You were waiting for an answer because you still couldn't believe it. Once he stopped laughing he grabbed his mustard bottle again. Then after another sip of his mustard he added: "And guess what..... I can even get drunk from mustard." That was it. Your jaw dropped open. You did not believe what he just said. You were sure that you looked pretty dumb but right now but you didn't care. With your jaw stilll open you started shaking your head. That caused him to lose his shit. He started laughing. He was laughing for 5 minutes straight. He stopped, wiping a tear of laughter from his eye socket. He got himself together and started to explain things to you. You weren't sure if you understood everything but you let him continue anyway. The rest of the evening you spent with eating and talking about a lot of everything.
