Underfell Sans x Skeleton Reader

Date

A loud banging on the door knocked you out of your sleep. You fell of the couch and landed on the hard floor. You groaned, having your spine make an unsatisfying crack sound when you got onto your feet. Still groaning you made your way over to the door. You were still half asleep when you opened the door. At first you didn't see anyone and were about to go back inside, but at the last second you noticed something on the floor. It was a smaller box, very fancy. You grabbed the box and went back inside, closing the door behind you. You sat down on the couch again. You went for the box first, it was wrapped in a blue wrapping paper with a red line and a red bow on it. You carefully opened the box, not wanting to damage the pretty wraping. Inside of the box were three other boxes. Two small ones and a bigger one. Was this going to be a box inside another box inside another box prank? You opened the smaller box, revieling a fancy display of a neckless. It was clean silver with a little half of a (f/c) heart hanging in the middle. It was beautifull, so naturally you put it on. It made you smile. You opened the other small box, bigger than than the first one but still smaller than the last one. Inside of that box were shoes. They were black with a not too high heel. On the front was a bow. They had a soft texture, inside and outside. You got a little worried. Not that they weren't pretty, no, they were so wonderfull. But you had tryied shoes like these before and none of them were comfortable. You put aside, since wearing shoes inside of the house wasn't really polite nor clean. Finally you turned to the last, and biggest, box. You opened it carefully. You didn't believe what was inside. It was a dress! Of course inside the box it was difficult to see how it truly looked. You touched the fabric. It was extremly soft and thin. Impatience got to you. You grabbed the dress from the box, lifting it carefully and let it unflod. It was a dark red dress. It had sleeves that went to your elbow. It was long enough to cover your knees but not longer. Around the top it wasn't showy at all. It tightened around the waist only to let the soft fabric fall out casually around the legs. It was beautiful. You were admiring the three wonderful gifts you had just recieved. You layed the dress carefully back onto the box. As much as you were happy, a few questions got into your mind. Who sent you these? Why did they send it? And what were you going to do with these? These were only three of the million questions in your head. Once again a you were pulled back into the living room by a knock on the door. But this time the knock was quieter, barely hearable. You got to the door and opened it. What you saw before you left you speechless. Outside the door was Sans. But what shocked you was how he looked. He was wearing an extremly dark red, almost black, suit. His face was ketchup red and he was not looking at you. He had his arms behind his back. "Sans? What is this?" You asked, unsure of why he had dressed like that. He looked at you for a split second before he did something you had only heard him do while he was scared: "(Y-Y/n-n), I...." He went silent. "I-I was g-going..to.." He stopped again. "I was going to..." He mumbled the last part but you heard nothing. "I didn't understand that." He tried again: "Would you..." He was reder than before. "Would you go ou-" He cut himself of. He took a deep breath, before almost yelling: "Wouldyougooutonadatewithme?!" You didn't understand anything. You cocked your head to the side. And for the last time: "(Y/n), would you go on a date......with me?" He looked away, afraid that you'd decline. Your brain stopped when his words left his mouth. "He asked you out" was what a voice in your head said. "He asked you out" the voice repeated. "He asked you out!" the voice shouted. At that your face turned into a smiley, before you shrieked at Sans, scaring said skeleton: "Of course i want to!" You hugged him tightly. It took him a few seconds before he hugged back. Everything made sense now. (Don't you mean everything made Sans now? XD) He was going to ask you out so he got you a dress for it. You let go and rushed inside to get dressed, shuting the door. You rushed over to the dress and shoes. While you were pulling on the dress you heard a loud "YES!" from behind the door, it caused you to giggle. You finished with the dress and sliped into the shoes. For your surprise they were extremly comfortable. You had never walked in heels before, so this was going to be a challenge. You carefully made your way to the door, not wanting to trip. You opened the door, seeing a waiting Sans at the lower end of the stairs. His jaw dropped open when he saw you. His eyes widened. He kept staring, making you feel uncomfortable and insecure. The insecurity washed away when he spoke: "You're looking fabulouse." You smiled at his comment. You attempted to walk down the stairs with the heel on. You made the first step, but the second one messed you up. You made a wrong step and lost balance. "SHIT" was your only thought when you closed your eyes expecting to hit the snow covered ground. Yet instead you got saved by two boney hands gripping you around your waist. Sans had caught you mid fall. Your faces were inches apart, causing you to blush. He pulled you up onto your feet: "First time in heels?"  You nodded. "Do you wanna change?" He asked. You shook your head: "I'll be okay." He smiled and held out his hand. You grabbed it without question. He started walking, making you follow him.
