(Underfell sans x reader (female)) UNDERCOVER

Cover ups

          Undyne had let you, Papyrus, and a few other guards have a day off since the extra patrolling has made everyone tired. You were glad you could walk around in just your black sweater and skinny jeans since Papyrus now knows that you're human. It felt a bit weird not wearing your robe which made you feel a bit exposed.

          You walk down stairs to see what's for breakfast as your stomach growls and see Papyrus flipping pancakes and wearing an apron.

"We're having pancakes I see." I say.

"YES, AND WE'RE ALSO HAVING E―"

          Papyrus had turned around and saw what you're wearing as a tinge of red appeared where his cheeks would be. You could tell he was staring at your breasts probably because your robe always hid them from him and also the fact that he's never seen your womanly figure before.

"My eyes are up here Papyrus." I say pointing to my face with teasing tone.

"S-SORRY, I'VE NEVER SEEN YOUR ENTIRE FIGURE BEFORE UNTIL NOW." He stutters.

          It's going to take Papyrus a little more time for him to adjust to your human-self and from what you've seen so far, it might take more than just a little time. He couldn't take his eyes off of you as you started to feel uncomfortable.

"Um, earth to Papyrus?" I say snapping my fingers in front of his face.

He realizes what he was doing as he see's his pancakes starting to burn.

"NOW LOOK WHAT YOU'VE DONE!" He says turning off the stove and scraping the charred pancakes of the pan.

"How was that my fault!?" I protest.

"YOUR LOOKS ARE TOO DISTRACTING! GO SOMEPLACE ELSE BEFORE YOU RUIN THE REST OF THE BREAKFAST I'M MAKING!"

          You walk away and ignore the fact that Papyrus was still staring at you from behind, you didn't have to guess where he was looking.

          You were trying to think of something to occupy yourself with and saw a small stand next to the couch that had a book on it. It was a joke book that seemed entertaining as you open it and find a quantum physics book inside. Confused, you open the physics book and found another joke book inside of it as you opened that joke book to find another quantum physics book inside if the joke book. 

          Realizing the pattern of this dilemma, you decide to stop and put the book back and stacked the other three books on top of each other that came out of no where. As you were trying to comprehend how a book could have infinite books inside of it, Sans was walking down the stairs and saw your puzzled expression at the new stack of the same two books.

"pretty neat, right?" Say Sans breaking your train of thought.

"Uh yeah, how does that work exactly?" I say pointing to the books.

"you'd have to be a science nerd to get the joke." He says winking.

         He sees that you're still confused and sighs. You do like science but you were never the best at it, especially if they were science jokes.

"ya don't get?" He says a bit sad.

You shake your head 'no'.

"that's okay, not many monster would find it funny anyway."

          You wondered if Sans still has the knowledge of a scientist but still have no memories of him and Gaster working together as royal scientists.

"Why do you like science Sans?" I ask.

"i don't know,  i've just always had a passion for it. why do you ask?" He says.
