Sans Aus x Reader Oneshots (Requests CLOSED)

Sans x Reader -le prank-

Undyne's POV:

"O-okay, here's the plan. Y/n and S-Sans are too dumb to realize that the other has feelings for t-them, s-so I have to h-help them!" Stuttered Alphys. The lizard had gathered me, Mettaton, Toriel, Asgore, Flowey, Frisk and Papyrus to talk about Y/n and Sans. Y/s/n was everyone's OTP, but the idiots didn't realize it.

"S-so what we're gonna do is-"

Your POV:

You sighed, you were waiting for Alphys, she was supposed to do an experiment on you, testing for determination or something. You were standing in her lab, petting some of the amalgamates.

"Hey, Alphys said she couldn't make it and she asked me to do the tests for her. Don't worry, I won't kill you. On purpose, that is." Sans joked, walking in. You smiled. "Sans!" You exclaimed. You hadn't seen him in a while and it was pleasant surprise to see your crush-GOOD FRIEND. YOU MEANT GOOD FRIEND.

"Okay, uh, if you could take out your soul, so I can check its health..." the skeleton trailed off. You nodded and took out the bright f/c soul. An interesting thing about you, was that your mood coukld be read from your soul. All you had to do was say the "magic" word. It wasn't anything special, just your soul trait. You explained this to Sans as he gently poked your soul and wrote some notes.

"Wow, really? Do you mind demonstrating?" He asked, impressed. You didn't mind, the only other person you had told and showed this was Alphys, and now Sans. They were your best friends, and they told you their personal secrets, so you were happy to tell them yours.

You nodded and murmered "(soul trait)." You blushed as your soul turned fushia. "What is it?" Sans asked. "What does it mean..?" "Um, it means, that is to say, uh, I'm feeling... in love...." You mumbled, embarrassed beyond words.

"If you don't mind me asking, with whom?" Sans asked, blushing too. "Usually, it's the person in the house, or...room..." You said, even quieter than before. Sans blushed even more as he realized what you meant. "O-oh." You finished most of the tests in silence.

Sans glanced down at the list of the tests Alphys had given him. "Alphys, I swear to Asgore..." he muttered, blushing again.

"What is it?" You questioned. "Umm, I have to...to do a full body X Ray." You paused, thinking about why that was so bad. "Oh. My. Gosh." You said, giggling uncontrollably. "That's so inappropriate for you!" You said, tears in your e/c eyes from laughter. This was fr*cking hilarious.

"Don't laugh! I feel like a perv!" Sans whined. "Not if I give you permission." You said, giggling and shrugging. "Oh my Asgore, I'm going to kill Alphys. Such a shipper." Sans said.

"Do I have to take off my clothes? I hope not, it's cold in here." You joked, noticing that this was really bothering Sans. "No, it's fine. J-just step behind the machine. I just need to check for broken bones and such." He said, motioning to a strange screen. You walked behind it. You heard Sans taking deep breaths as he turned it on. You snorted, smiling.

"Okay, I just need to to spread out your feet and put your arms out." The skeleton instructed. You did as you were told and waited a moment. You heard a little squeak of embarrassment from Sans as he looked. "I hate you, Alph." He muttered, taking some notes hurriedly, then turning off the machine. You stepped out from behind it and saw Sans' completely blue face.

"You're adorable." "I still feel like a perv!" he whined, blushing and covering his eyes. You hugged him and giggled. "Come on, let's go to Grillby's to get your mind off it." You suggested, grinning. He nodded and started walking, super slowly. You rolled your eyes, picked him up bridal style, and started taking longer strides, trying to get the both of you out of the snow. You giggled again as you saw his completely blue face.

"Y-y/n! W-what are you doing?!" He yelped. "Calm down, you sound like Alphys!" You giggled. "I'm just getting us there quicker!" You explained, smiling. He covered his face in his hands and allowed you to carry him, wrapping his arms around your neck.

"Screw gender stereotypes!" You yelled as you pulled out a tiara and placed it on the skeleton's skull. Sans chuckled as you arrived in Snowdin at full speed, sprinting.

When you got to Grillby's, you decided to share a milkshake. D*mn you, Grillbz! The fire monster had put two, heart shaped straws in the pink shake. You blushed in unison with Sans.

You and the skeleton leaned in for a sip at the same time, bumping your s/c nose against his teeth, unintentionally making him kiss your nose. A flash went off. Sh*t.

"Alphys, you fr*cking fangirl!" You yelled, springing to your feet, your face red. You heard a giggle, and the lizard, a one eyed fish, a robot, two goat monsters, a flower, a small human, and another skeleton came out of their various hiding places, holding polaroids of various moments from the day with you and Sans.

"W-well, we got them to go on a date, w-willingly at that!" Alphys stuttered, high fiving Undyne as the fish grinned. "Fuhuhu! Mission accomplished!"

"Hey Undyne, I think you meant-" "SANS DON'T YOU DARE!-" "Fish-ion accomplished." Papyrus groaned. "UNDYNE, WE WALKED INTO THAT ONE, WALKED!" He yelled, face palming. Sans snorted as Undyne fell to her knees and stared at her hands. "How did I not see that coming. This is a sad day indeed." She muttered, a single tear dripping down her face, along with Papy's. You burst out laughing, then people started handing Alphys all the polaroids, and then the lizard placed them in a scrapbook, titled: "Our love, from start to finish ♡"

"Alph, I swear, I'll die of embarrassment at your scaley hands." You said, smiling taking the scrapbook anyway, and flipping through the pictures of you and Sans. One was of you both at the zoo, right as you smushed your half-eaten ice cream cone into his face. Ahh, good times.

Welp, might as well get another picture for the cute scrapbook. You grabbed a polaroid camera from Papy, then put it in the "selfie position", showing your and Sans' face as you kissed him on the lips. Everyone else gasped and snapped pics too, and you looked at the one you took, smiling. Sans mumbled something, then sat down, dazed at.

16 years later:

You flipped through the scrapbook, smiling as you saw the picture of you and the skeleton in Grillby's, kissing, with your hand writing on the bottom.

"First Kiss ♡♡♡"

You turned to your left, kissing Sans on the cheek as you gently rested the scrapbook on you lap,, the ring on your left hand glittering.
