Sans X reader! A undertale fanfiction

Nightmares

(Y/n)'s pov~
You watch sans walk downstairs thinking about what to wear to bed knowing You didn't bring anything with you, You continue to roam around in the closet until You find a pair of black shorts and a white tee shirt, You strip and throw yoir close to the side putting his clothes on, hoping he didn't mind, the pants seemed to big so You digged around and took the elastic from your pocket and bunched up the loose end of the shorts making them fit nicely, You look at yourself smiling and putting the rest of his clothes by the door before hearing someone enter the house "SANS! WHERE ARE YOU?" There was a long period of silence before sans spoke up

"I'm right here bro..you uh..need something..?" Papyrus walks into the kitchen and then back into the living room.. "SANS WHERES THE HUMAN..?" He sounded a bit nervous as he paced around the room " I was talking to undyne and she went all crazy hearing about the human!" There was a long period of silence "s-she's not here, sorry paps" I smile and walk to my room, making it look like normal, I open the door stumbling right into (y/n) making her fall to the floor  "s-sorry I didn't s-" I cut her off by covering her mouth"SHH, you've got to stay quiet, I told my bro you're not here "she stares at me making me blush, seeing her in my clothes "I hope you don't mind...it's just I got nothing to wear... "She gets up off the floor seeing her limp to the bed, I quickly walked to her with a concerned look "I-i didn't hurt you did I? ""No it was the door... It hit my knee and it stings a little "I quickly pick her up and placed her on my bed "Don't push me away all right... I'm going to help "smile little awkward and open my mouth revealing some fangs and my blue ectoplasm tongue I can see her blush as I gently lick her leg.

You didn't push him away like he asked, just squeaked a bit, his tongue was warm and soft against your knee the pain disappeared slowly "y-you can stop now.." Your face is really dark red, shortly after he stops and looks at you "it's pretty late... You should get some rest... "He smiles calmly putting blanket a blanket over you, the blankets were soft and warm compared to the orphanage, there they were full of dust and scratched your skin, you slowly fall asleep from the warmth as he sits on the floor paying attention to your sleep
((Time skip to middle of night))
Tou have a weird dream about a person around your age, she had red eyes an light brown hair, she wore a green and tan shirt, You yell loudly not intending to wake sans, he rushes to your side and gently shakes you to wake up "(y/n)! Are you alright..!" There was nothing said, you just cryed softly, in the dream chara had tryed killing you, saying she'd take control and kill the ones you loved.. "(Y/n) please tell me what happened.." He sounded sad as he looked at you "I-it was a nightmare...nothing to worry about.." You sigh wiping the tears from your eyes and lying back down, he comes and cuddles you telling you it's alright
