Sans AUs X Reader and One Shots

Underswap sans x reader

Your POV

As I skip into the house being my giddy self I see my crush sans smile at me with a plate of his great tasting tacos! I smile back as he says " HUMAN! YOU'RE HOME! THE MAGNIFICENT SANS HAS MADE TACOS FOR EVERYONE!" I giggle at his cuteness and ask " can I take one?" He smiles wider and nods his 'head' ( should I put skull instead? Nah! XD ) as I walk over and grab one I hear papyrus walk down the stairs. I felt a pun coming on so I tried not to smile before he said it. ( me too lazy to write pun and I don't know any taco puns XP )
"REALLY PAPYRUS!? UUUGGGGHHHHH!!!!" I snicker when he screams at papyrus for doing puns while I start eating my taco.

~~~Time skip~~~

It was time to put sans to bed so I got his favorite book 'The Three Happy Duckling's' ( just go along with it ). After I finished it I headed for the door. But before I could exit sans stopped me and asked " h-hey (y/n)? Ca-can you give me a good night kiss?" I blush at his question and turn around. "S-s-sure blue!" I gave him a kiss on the forehead and said goodnight before smiling and turning off the lights.

In the middle of the night I felt something poke my face. I groaned and opened my eyes to see a frightened sans. My eyes widened and I sat up quickly alarmed. I looked at him and asked " are you okay!?" He shakes his little head and whispers " no...I had a nightmare so I came in here to ask you if I could sleep with you tonight?" How could I say no to a kawaii face like that!? So of course I said yes and pulled up the blanket beside me so he could slip in and snuggle with me. I was surprised when he became warm. I guess skeletons aren't cold all the time, I thought and sighed falling asleep.

Sans shifted and woke me up by snuggling deeper into my chest that he was apparently using as a pillow. I looked down at him and smiled blushing madly. He was adorable when he was asleep! A few minute later he woke up and started to blush realising where he is.

I was sitting on the couch watching nappstabot on the television slowly falling asleep. Blue came over and snuggled next to me on the couch... Purring!? I looked down at him seeing he was literally purring. I giggled and slowly dosed off.
I was awoken yet again to sans cuddling onto my chest. I thought ' bruh! Seriously!? Am I a pillow now!?'
He then woke up. Again blushing realising where he was. I blushed and looked away not wanting him to see.

Something was odd about sans today cause he looked at me all dreamy and everything.
The next day the samething happened, I fell asleep on the couch, sans comes and cuddles, and makes my chest a pillow, blushes seeing where he was, and me blushing and looking away. But then when I looked back blue had a different look in his eyes ( lust!? BLUEBERRY SANS!!! YOU ARE TO INNOCENT!
Blue: BUT AUTHOR~CHAN!!!!
Me: NO BUTS MISTER!!!>:(
Blue: hmf! *crosses arms over chest* )
I looked at him puzzled and scared at the same time. What has happened to my sweet blueberry!?!? I thought as my thoughts were interrupted by a slimy thing on my neck.
( WARNING: THIS IS NOT A LEMON!!!! )
I looked at blue and realized that the slimy thing was blue's tongue! I shivered as he licked my neck. Biting my lip I told myself to not moan and show that it felt good. Blue saw me bite my lip and smiled knowing that I was holding back. I couldn't hold it any longer and let out my moans. His smile turned to a lust smile!? All of a sudden papyrus burst through the front door and said "hey guys there's a human in Snowdin!" I jumped off the couch and raced out the door. I saw a little girl with short brown hair, brown eyes and she was wearing a blue sweater with a purple strip going across her chest and brown shorts with boots. She was holding Temmie in her arms peacefully walking along in the snow.

~~~A few years later~~~

It has been a few years since we've met frisk the human.
Sans has gotten closer and closer to me over the years. I'm going to ask him if he wants to be my boyfriend soon, as in tomorrow.

~~~The next day~~~

I got everything ready, so now all I need is to do is ask sans the question.
I saw him approach me with his cute smile. I smiled back and guided him to a picnic I've made for us.

After eating I brought him to the tree that gave us our shade. I held his hands in mine and looked him in the eyes. I took a deep breath and said " blueberry sans, will you be my boyfriend?" He gasped and said " of course (y/n)!" I Hugged him tight and kissed him passionately. This was the best day of my life! But not the only one.
