Their little Frisk (Undertale fanfic)

❤️fifteen❤️

I was trying out Papyrus's new puzzles the next morning during breakfast while waiting for Mettaton to come by and visit.
Poor Papyrus had been cleaning the house spotless from any small dust bunny hiding in the corners at all.
Tony joined me in Papyrus's oddly fun puzzles which I found cute of how most of them were crosswords and questions like..
WHAT IS MY FAVORITE FOOD?
Or something we had to guess about Paps which made me snicker.
Sans of course was sound asleep on the couch from using too much 'energy' in helping make breakfast (sarcasm).
Once I had finished Papyrus's puzzles I watched him run back and forth with cleaning supplies.
Mettaton was Papyrus's biggest idol and I never questioned it.
"Is he always like this?" Tony asked sitting beside me on the right as I sat at the end of the table.
I waited a moment watching Papyrus scrub the wall so clean not even a smudge was left.
"Pretty much," I shrugged not taking my eyes off of Paps.
A knock was heard at the door which could probably be Mettaton as Papyrus started to fan out on us.
"SANS!! GET THE DOOR YOU LAZY BONES!" Papyrus yelled at his older yet shorter brother who was napping and drooling on the couch.
Sans's magic eyelids opened as his tired white orbs looked like they were about to die out as he sighed wiggling in his seat.
"Kid, get the door," Sans called to me not moving a muscle which made Papyrus face palm himself at the laziness of his older brother.
"Whatever you say bonehead," I sighed under my breath before getting up forcing my weak little legs to shuffle towards the door.
Sans huffed at me but didn't move otherwise.
I opened the door to see the strangest yet fabulous tall robot.
His pink eyes held a passion clear he was born or.. Made to be a star.
His black hair barely touching his shoulders as he rocked the pink chest plate and pink high heel boots. He wore a darker shade of pink as eyeshadow as he stood there like a freaking SUPER MODEL!
"Oh! Hello! You must be Frisk! I've heard so much about you," Mettaton bend over a little since I was shorter to greet me at my height.
"You must be Mettaton, Papyrus tells me a lot about you," I shook his extended hand as he smiled widely at me.
I invited him inside as he walked past me before I shut the door.
"METTATON!!" Papyrus squealed like a fan girl coming over to greet the robot.
"Papy! Oh my~ how've you grown," Mettaton grinned as his cheeks dusted a light pink that suites him honestly.
Tony came out around the corner with a friendly smile already getting acquainted with Mettaton.
Sans finally got up causally walking past us as he gave Mettaton the stink-eye which made me frown.
"Sup garbage can," Sans nodded in a cold greeting when he stopped for a split second just to say that.
I elbowed him in the ribs which made him lose air for a moment but he shook it off.
"Sans..." Mettaton greeted back just as coldly with no smile appearing on his face when he said his name.
Tony thankfully got rid of the awkward environment while Papyrus scolded his brother for such behavior but not as much seeing I had elbowed him in the ribs for half his punishment.
Me and Mettaton talked for awhile mostly drinking tea and when I me and Mettaton I mean just mostly Mettaton.
His ego was bigger then Papyrus's love for spaghetti and puzzle put together.
Don't get me wrong he was a nice guy but geez... If not his ego, we talked about his cousin who actually sounded like an adorable lost kitten.
"~so then I told my cousin Napstablook he should preform for my show! But I never can convince him, he makes remixes that are absolutely AMAZING!~" I listened carefully to every word nodding in response.
If you tune out people's conversations then you might miss something that they wanted your opinion on, I learned that the hard way..
Wasn't long before Papyrus joined us onion the conversations as the two started to soak in each other's presences and get more involved in each other forgetting I was there.
I shrugged as Tony started to offer me more tea or cookies seeing he was equally tired and bored.
Sans had disappeared to his room doing (who the hell knows what).
I heard a crash upstairs making me flinch in alarm as we all exchanged concerned looks knowing it came from Sans's room.
"SANS?!? ARE YOU OK BROTHER?!" Papyrus yelled up to his bro.
There was a small weak "I'm fine" that spoke from in Sans room.
Everyone's eyes and eye sockets landed on me expecting me to do something.
I rolled my eyes setting a cup of tea I had in my hands down reassuring everyone I'd go check on him.
Tony had a frown on his face out of the corner of my eye I could see the hate welling in his face.
When I reached Sans's room I gently knocked on the door slightly putting my ear against it to listen for any response.
I could only hear the three talking downstairs making me growl mentally.
I opened the door seeing it was unlocked and also pitch black as light spilled in from the hallway.
"Sansy?" I questioned.
There on the bed I saw Sans had his head in his hands with his coat tossed to the side only in his white shirt as well as a broken glass vessel on the floor.
"What's the matter?" I asked in concern as I shut the door lightly behind me flipping on the light.
"Huh?!" He seemed surprised by my entry as his orbs locked on me. "Oh, didn't see you there Frisk. I'm just, chilling," he shrugged as I noticed he didn't make a pun.
I smiled sadly as I crept over slowly beside him when he turned his gaze back down at the broken glass I decided to ignore for now.
"You look a little.. Bonely... Need some company?" I sat beside him on his left with a soft smile.
He chuckled barely at my attempt of a pun.
He glanced at me sweetly with a look I did not recognize.
"How could I say no kiddo?" He ruffled my hair making me giggle like a child.
"Like to explain why that's broken?" I asked calmly pointing to the glass.
He cheeks burned a blue hue after a moment as he looked away from me.
"Accident," he simply said not really wanting to take the conversation further I let it go.
"Why do you hate Mettaton?" I asked cocking my head to one side innocently.
Sans scoffed almost in amusement.
"If it wasn't obvious before, Mettaton and Paps... Eh... Like... Each other... And Mettaton is a real pain in the~" I gave him a hug in reassurance.
I know how much he loved his brother and how much he wanted to protect him in anyway he could.
He seemed a little shocked but returned the hug tighter then most times as if he needed it.
"It's ok Sans," I murmured into his shirt.
I feel his smile widen at me as he stroked my head gently as I eased into his touch now finding why animals like this kind of attention.
My heart skipped a beat feeling an emotion I could not yet grasp on my hands for some unknown reasons when I pulled away.
His boney hands were cold compared to my freakishly warm ones making me frown.
I took one hand and sandwiched it in between my own to warm them which he had noticed what I was doing and smiled gratefully at me with blue covered across his cheekbones.
"When are you going to show me that secret place you've been talking about for years now?" I questioned changing the subject to help him get his mind off Mettaton.
He chuckles and rubbed the back of his neck nervously with his free hand.
"Dunno, maybe sometime this week," he winked at me which made me feel butterflies of how excited I was to see what Sans had been describing to me for the past seven years.
"Oh Frisk darling~" I heard Mettaton call as I glanced over my shoulder.
I turned back to sad looking Sans knowing I was leaving him for now.
"Love you Sans, don't stress," I assured him giving him a quick peck on the cheekbone before slipping away and running back downstairs.

~And little did she know how much she captivated him~
