(Underfell sans x reader (female)) UNDERCOVER

Promise

          You were hoping you would get more time to sleep on the day of the ball since Undyne was practically giving all of the royal guards the day off. You were woken up from Papyrus flinging your blankets right off of you with a great amount of force.

"WAKE UP (Y/N)! JUST BECAUSE WE DON'T HAVE TO PATROL TODAY DOESN'T MEAN YOU GET TO BE A LAZY ASS JUST LIKE SANS!"

          Waking up startled so suddenly from Papyrus caused you jolt right off the edge of your bed and groaned as you fell onto the floor. You attempt to roll under the bed so you could fall back asleep but Papyrus had grabbed your ankle and pulled you out from under.

"COME ON DON'T MAKE THIS DIFFICULT, IT'S ONLY SIX O'CLOCK IN THE MORNING!"

You let out an annoyed sigh knowing that you weren't getting back to sleep anytime soon.

"Papyrus, why in god's name did you wake me up at six in the fucking morning?" I say rubbing my eyes that were still adjusting to the light.

"BECAUSE YOU AND SANS HAVE UNFINISHED BUSINESS FROM LAST NIGHT THAT YOU TWO NEED TO CARRY OUT ON."

          Before you could say anything, Papyrus had thrown at you a large paint stained apron and a t-shirt that had specks and spots of paint on it as well. You remembered what you and Sans had done to Papyrus' kitchen and that you promised to repaint it. You tell Papyrus to leave your room so you could get dressed and maybe sneak in at least five more minutes of sleep.

"AND DON'T EVEN TRY GOING BACK TO BED (Y/N)! I WASN'T BORN YESTERDAY!" Papyrus shouts through the door.

          Now feeling more ticked off now since your plan to go back to sleep had failed, You put on the t-shirt and apron only to realize that you only had one pair of nice pants that you didn't want to ruin with paint. Luckily the apron that Papyrus had given you was most likely his which was big enough to be used as a skirt. You wrapped the apron around your waist and tied it from the front and quickly put your hair up away from your face and to avoid any paint from getting in it. You walk out and saw Papyrus waiting for you to come out as you ignored him and dragged yourself down stairs to the kitchen, already able to smell the scent of fresh paint.

          You walk into the kitchen only to see Sans leaning against the wall on his left side while still holding the a dripping red brush as it dangled above the bucket of crimson paint. Papyrus saw this and snapped at him.

"SANS, WAKE UP! (Y/N) IS HERE NOW SO GET THAT LAZY ASS TO WORK! I WANT THIS ALL DONE BEFORE WE LEAVE TO THE BALL!" Papyrus says as he walks to the front door.

"and where do you think you're going?" Sans says groggily and sounding just as annoyed as you were.

 'I'M GOING TO HOTLAND WHERE THE BALL IS BEING SETUP AT THE MTT RESORT AND I'M GOING TO HELP METTATON WITH THE PREPARATIONS!"

"paps bro, i don't think anyone is going to be awake right now―it's almost five a.m." Sans says yawning.

"Wait, what!?!? But you told me it was six Papyrus!" I say confused and angry.

"I KNOW HOW DISTRACTED YOU BOTH GET, ESPECIALLY IF IT'S JUST THE TWO OF YOU TOGETHER! SO I TOOK THE LIBERTY OF WAKING YOU AND SANS UP EARLIER SO THE JOB WOULD GET DONE AT THE ACTUAL TIME OF WHEN YOU APPROXIMATELY SHOULD BE FINISHED!"

"And what time would that be?" I say gritting my teeth.

"SOMEWHERE AROUND SIX TO SEVEN THIRTY P.M. NOW LESS CHATTING AND START PAINTING!"

And with that, Papyrus had left leaving you with Sans who was starting to fall asleep again.

"Aren't you mad Sans that he tricked us to waking up this early?" I ask Sans as his eyes open wide the moment you spoke.
