Undertale/AU X Reader one-shots

Gaster!Sans X Reader

It was a cold night. . . Your parents had just kicked you out of the house because you forgot to put the clothes in the washer. Again.
Flashback
"Y/N! THIS IS THE FINAL STRAW! IF YOUR NOT GONNA DO ANYTHING IN THIS HOUSE TO HELP, THEN YOU'RE NOT LIVING HERE!" Your mother was shouting, you dad drunk on the couch, gambling with some of his friends from his job.
  "Your mother is r-," He burped loudly. ", right. You need to help more."
    You snorted at him. "I need to help? Look at you, all you do is play poker and fuck other women." You raised your voice. He looked angrily at you, quickly standing up and reaching to slap you, but your mother beat him to it.
  Your cheek stung, but you managed to stay standing. "DO NOT RAISE YOUR VOICE LIKE THAT, DO YOU UNDERSTAND ME, YOUNG LADY?!" (Sorry if your male)She yelled more.
  "GET OUT OF MY HOUSE!"                           You practically threw yourself towards the door, swinging it open then slamming it shut. You lifted your hands to your cheek, feeling warm liquid.
  Blood. You thought.

End of Flashback

  Your blood trailed down your face, onto your shirt as you kept walking in the cold. "H-holy fuck." Was the only thing you could manage to say.
  "Lost, Y/N?"
  You spun around, only to come face to face with. . . . . Nothing? That didn't make sense, you knew someone had spoken directly to you.
  "Isn't that a shame. . ."
  You spun around again, and again meeting nothing.
  "Must be wondering who I am. . ."
  The voice was beside you now, and you moved your eyes towards it. Nothing.
   "Must be wondering how I know who you are. . . Are you not?"
  This thing was getting in your last nerve.
    After spinning in a complete circle, you decided to speak up. "Stand fucking still so I can actually see you!" You said angrily.
  "Heh, that just ruined the fun, but whatever." You felt a hand caress your still bleeding cheek. You twitched at the sudden touch, but quickly relaxed. There was a quick shove on your chest. The thing now had you pinned up against a brick wall, but the thing wasn't actually a thing, it was a monster. A skeleton to be specific.
  He wore all black, beside grey pants and a yellow light in his right eye. You blushed as you realize he was hand- some. His black jacket only appeared to go half way down, covering his. . . Ribs?
On the shoulders were two dragon looking creatures, with sharp,terrify-       ing teeth.
  "Why are you bleeding, girly? A pretty thing like you shouldn't be walking out here at night." He seductively smirked at you, causing you to blush more then you expected.
  "I uh, was just taking a stroll, when I tripped. . ." That sounded about right. You hoped he would fall for that lie.
  "Listen, I may look stupid to you, but I'm smarter than an average human, and that just sounded incredibly fake. I've been watching you." Well, that didn't sound stalkish at all. You blush at his words, which you thought you were tomato red by now.
  His hand finds its way to your cheek again, and caresses it some more, sending shivers up and down your entire body.
  "M-my mother kicked me out of our house, and I yelled at m-my dad, then s-she slapped m-" He cut you off by cupping your cheeks into his hands.
  "She hit you?" His tone turned serious as he stared deeply into your eyes, and it felt like he was almost seeing through you.
  You nod your head, your eyes retreating from his gaze. You heard him sigh as he removed his hands from you face.
  "So now I guess you don't have anywhere to live?" He broke a short moment of silence. Again, your only response is a small nod.
  "Here, take my hand. You can stay at my place until you can go back to your house, okay?" He held his hand out, waiting patiently for you to take it. Both the palms of his hand had one hole in each, making you think Doesn't that hurt him? But you didn't get to think anything else before you reached out and took his hand.
  He smiled a warmhearted smile, enough to melt your heart with his stare. There was a flash and you appeared in a seemlessly small room.
  "This is a room, not a hous-" Again, he cut you off, forcefully shoving you towards a small bed in the corner of the small room.
  "Sit down. I'll go grab some bandages." He opens a door that seemed to be camouflaged with the wall. As you sat there, doing absolutely nothing besides fiddling with your thumbs, you decided to think over everything important so far.
1. You met a hot skeleton.
2. He invited you over to his house.
3. You are now on his bed.

  "Does is still hurt?" You were snapped back into reality, with the skeleton kneeling down, inches from your face. You started to blush again.
  "Not really, but I think it's sore."
He opened a small bottle, poured some of its contents on a rag, and reached to your face.
  You flinched a little, scared that it would sting. "It might sting a little, but you'll be fine." He reassured you.
  You then closed your eyes, ready for the wet cloth to come in contact with your cheek. When it finally did, you realized, it didn't hurt as much as you thought it would.
  You smiled at the mysterious man, who smiled right back.
  "T-thank you."
  "No problem, Y/N."
But you were still confused on how he knew your name...

Ooh. I'm sorry for the late one-shot, but I got so many requests that I couldn't just choose 1! Again, thank you all for not going insane... I hope...- Author
