AUTHOR NOTE:
Hiya! If you're reading this, thank you! I'll try to keep it short and sweet, I promise!
This is my first time writing FanFiction. I've writing original stories before, but I've never taken someone else's character and placed them in my own story. So I hope you enjoy it! This particular story has been gnawing at me for some time now, and I hope you all enjoy it as much as I do.
And I promise this story won't be full of science stuff! Just the occasional pun, and enough science talk to show what a nerd Sans is (or at least, to the caliber I think he is). Also, I'm planning on it being a medium burn. I don't want it to be slow, but I also want there to be some plot, you know? So yes, I do plan on there being some smutty sin later on! Of which I will specifically mark for those who wish to skip it, or are only here for that. Okay, I'm done rambling now… Thank you again!
Chapter 2:
The next day finds you sitting in your tiny office, contemplating if you should contact Sans or not. 'It's only his second day,' you think to yourself as you stare down at your phone. 'He's probably still getting settled in over there. Even though I really want to get started on this project, I don't want to bother him if he's busy.' After weighing your options, you finally decide to stop acting like a child and walk over to the Physics building. You'll offer to help him get settled in, and then if there's time you could inquire about the project. If he refuses your help, or is too busy, well... Then you would return to your office and come up with a Plan B!
As you're walking towards your destination you hear a loud, slightly high pitched voice coming from somewhere to your right. When you turn to look, you see a rather tall skeletal monster trying to get the attention of a group of students. They look at him for a second before ducking their heads and briskly walking away. Anger prickles at the back of your neck as you turn and start walking towards the monster. Even though he has a permanent smile etched into his skull, you notice pseudo eyebrows creased with confusion. You chalk it up to magic.
"Excuse me. I'm sorry about those students, but I'd be more than happy to help you," you say with a smile once you get close enough to him. His face lights up once you make eye contact, and he closes the gap between you two in two long strides. In fact, you almost bump in to him since you can't stop walking fast enough. As you're trying to put a little distance between you, he starts talking rapidly.
"THANK YOU, HUMAN! I, THE GREAT PAPYRUS, AM LOOKING FOR THE PHYSICS BUILDING. YOU SEE, MY BROTHER FORGOT HIS LUNCH THIS MORNING AND SINCE I AM SUCH A GREAT BROTHER I DECIDED TO BRING IT TO HIM!" Papyrus beams at you as he holds up a large tupperware full of what appears to be spaghetti.
"Oh, are you Sans' brother? I'm actually on my way to see him right now! My name's (y/n), by the way." you reply, your smile widening fractionally. Even though he is quite loud, you can't help but like Papyrus. His good mood is rather infectious.
"WAIT," He yells suddenly, causing you to jolt back in shock, "ARE YOU THE DORKY CHEMIST WHO HAD LUNCH WITH SANS YESTERDAY?"
"Um, y-yes?" Your reply is more of a question than an answer, but he seems satisfied nonetheless. You're still trying to wrap your head around the fact that Sans referred to you as a dork to his brother, when suddenly the tupperware is shoved at you.
"IN THAT CASE, I TRUST THAT YOU WILL GIVE THIS TO MY BROTHER. WALKING AROUND THIS CAMPUS SO LONG HAS MADE ME RATHER LATE FOR WORK. THERE'S PLENTY THERE FOR YOU AS WELL. THANK YOU, (Y/N)!" With that he turns and walks off with a "NYEH HEH". You stare at his retreating form, blinking slowly, before turning and walking back towards your original destination.
It takes asking a few people for directions before you finally make it to where Sans is supposed to be. You knock on the closed door you were directed to, which is apparently his office. When you hear what sounds like a muffled "come in", you ease the door open before peeking your head in. Sans stares back at you from behind a desk, looking as if he was filling out some paperwork. As you step through the door, you can't help but notice his office is more of a glorified broom closet. There's just enough room for his desk, a small bookcase, and two chairs that sit in front of his desk.
"Hey," his voice breaks you from your inspection. "I was wondering when you would drop by. I was starting to feel rather bonely."
You chuckle as you take a seat, and reply: "Tibia honest, I wanted to make sure you were settled in before I came over and bothered you. Oh! You'll never guess who I ran into on my way here." You sit on the edge of the chair, with the tupperware hidden behind your back, grinning at the skeleton who looks back at you in confusion. "I'll give you a hint: He was rather upsetti that he couldn't find you." Understanding flashed in his eyes, and he chuckled.
"Oh, you met Pap?" You nodded as you handed him the tupperware, giving him a quick version of your interaction with his brother. He looked slightly irked when you mentioned how the students ignored his brother, but gave you a genuine smile once you finished. "Thank you for helping him out. Who noodles how long he would have wandered around if you hadn't helped him."
You sigh and give him a small smile, "Yeah. It's sad that you have to thank me for something as simple as that. I'm sorry humans suck so much." He arches a pseudo eyebrow at your comment, and turns to place the tupperware on the bookshelf.
"Things are getting better, though. Pap recently started apprenticing at a restaurant close to home. Once we made it to the surface, he decided he wanted to be a chef. He's gotten a lot better at cooking because of it, and he seems pretty happy," Sans hummed, looking down at his papers thoughtfully. "Then I get a call saying my application had been accepted, which I never thought would happen. Still, it's a good sign that monsters can start coming further in to the city. It seems like things are finally starting to go our way, you know?" You nod in agreement.
—
The next few weeks go by in a blur. You spend quite a bit of time with Sans each day, doing various experiments and cracking puns. Sometimes, it doesn't even feel like you guys are working. In fact, with each passing day you feel like you're growing closer to the goofball, and even start to consider him a friend and not just a coworker. Apparently he feels the same, because one day he asks you something that catches you off guard.
"A party?" you ask, making sure you heard correctly. He pauses in his jotting down of observations to look over at you and nod.
"Yeah. Tori wants to throw a party to celebrate Alphys and I getting hired. Since you're my partner in crime, I thought it'd be neat for you to be there," he replies before turning back to his notes. "You don't have to if you don't want to, though. I wouldn't want you to be-"
"I'd love to come," you say quickly, cutting him off. "Just let me know where and when, and I'll be there. Should I bring anything?" For a spilt second you wonder who this "Tori" is, but shake the thought from your mind. 'That is so not your business,' you think to yourself. Sans taps his pen against his chin thoughtfully for a second, before flashing you a smile and giving you the answer you knew was coming.
Three days later, on a Friday afternoon, you're standing in front of a nice brick home, clutching a plate of freshly baked cookies. Your first thought is 'wow' followed by 'I really hope I'm at the right place.' You even check the address Sans gave you for the third time before nodding to yourself and walking up the steps of the porch. The home is of medium size, made of brick, and has a white picket fence around it. In the setting sun the flowers look beautiful, and you can hear the faint hum of voices behind the door. After taking a deep breath, you give the door a couple of knocks.
In a matter of seconds it swings open to reveal a tall, blue skinned (well, scaled) monster. You assume this is the Undyne you've heard about, and offer her a smile before trying to introduce yourself. Trying being the keyword there.
"You must be the nerd Sans was talking about! Don't just stand there Short-stack, come in!" She exclaims, pulling you through the door by your elbow. She's not quite as loud as Papyrus, but certainly could rival him in enthusiasm. You follow her through the hallway and into the living room, still clutching the plate of cookies as if your life depended on it. The chatter stops as soon as you walk through the door.
There are several monsters in the room, but none that you recognize. One of the monsters steps forward and stretches out a hand to you. "Hello! You must be (y/n). We are all so glad you could make it. My name is Toriel." Her voice is so warm and welcoming that you can't help but smile.
"It's nice to meet you, Toriel. Thank you so much for allowing me to come!" You attempt to shake her hand, but nearly drop the plate of cookies in the process. She helps you catch the plate just before it falls, and laughs with you before taking it gently.
"You didn't have to bring these, dear. Your presence is already such a treat," she teases as she walks toward what you assume is the kitchen. It took you a second to realize she made a pun, to which you chuckle lightly.
"You know, Sans didn't mention how short you are!" A hand is roughly placed on your head, causing you to flinch. You look up slightly to see Undyne staring you down. For a second you two stand there in silence, until she starts ruffling your hair and lets out a hearty laugh. "Hey Frisk, get in here! I want to see how close you and Short-stack are in height." You already know what the results are going to be, since Sans has teased you several times about being shorter than a twelve year old, but you decide it's best to humor Undyne (see note at end of chapter).
A young girl comes out from the kitchen, and smiles when she sees you. When she comes to stand next to you, she is indeed about two inches taller than you which puts her at 5'5". Undyne howls with laughter, with several of the other monsters joining in. You turn to Frisk in hopes of striking up a conversation. She smiles at you, and makes a gesture with her hands causing you to be confused before you catch on. Undyne seems to notice, and starts to explain.
"Frisk doesn't talk with words, but with her-" she trails off when she sees you signing back to Frisk. Frisk is taken aback for a second, but starts to sign back to you excitedly. You're a little rusty, but you manage to keep up. The two of you talk about her day for a little while, not noticing Toriel returning to the living room with Sans and Papyrus in tow.
You jump when Sans brushes his hand against your elbow, catching your attention. "You never told me you knew sign language."
You smile mischievously before replying: "Yeah, I'm glad I took sign language in high school. It's coming in rather handy."
There's a pause in all conversations before Papyrus lets out a groan, and cries out: "NO, NOT ANOTHER ONE!" A few chuckles follow his outburst, and you return your attention back to Sans and Frisk. You notice that she's slowed down her signing, and is being much less intricate. 'Ah,' you think to yourself, 'I bet Sans is learning how to sign.' You smile at how focused on her hands he is. Not wanting to listen in (or look on) their conversation, you turn and walk to the couch. There's a vacant spot next to a monster who looks similar to Toriel, only bulkier and taller.
"Is it okay if I sit here with you?" you ask the monster. By appearance, you assume this monster is a male, and your theory is confirmed when he answers you.
"Of course! It's nice to meet you, (y/n). My name is Asgore." You shake his outstretched hand before sitting down next to him. The two of you chat for the next couple of minutes, and you learn that he works as a gardener at a nearby school. He tells you of how it's one of the few public schools that teach both human and monster children. The pride he shows when he tells you of how great a teacher Toriel is causes you to smile. Speaking of Toriel, you look up to notice her making her way to the couch.
"I'm sorry to interrupt, but I was hoping I could borrow you, (y/n). If you wouldn't mind, I could use some help in the kitchen," she explains softly, smiling down at you. You tell Asgore 'bye' for now and stand to follow Toriel as she navigates through the crowd and into the kitchen. It's a pretty decent size, and opens up into a dinning room that has a table of which is currently covered in plates of different sizes and contents. You help Toriel arrange the plates so that it's a buffet style, where people can grab what they want before returning to the living room. She tells you that there's about ten people total, including the two of you, which means there's not enough room in the kitchen to sit together comfortably. Instead, you all will sit in the living room when it comes time to eat.
"(Y/n), dear, can I ask you something?" Toriel suddenly speaks up, sounding rather solemn. When you nod apprehensively, she continues. "Please know that I mean no disrespect when I ask this. However, I need to know the answer. Do you truly support our cause?"
Her question surprises you, and you try to keep the shock from spreading on your face. You keep eye contact, and answer firmly; "Of course I do. I wouldn't be here otherwise, Miss Toriel." Her somber look lets up slightly, and she nods. You feel as if she needs further convincing, so you continue. "I know you guys have met a lot of opposition since you've surfaced. And I know most of that opposition comes from the humans who live in the heart of the city, like myself. But I can promise you that there are several humans there who believe that monsters deserve to have the same rights humans do."
She smiles at you a little more warmly, but you can tell she's still a little apprehensive. "Thank you, dear. You seem very genuine. Please forgive me for being suspicious. When Sans told me about you, I wasn't sure if you had some ulterior motives. We've had a lot of troubles with those silly gangs, and my first thought was that perhaps they were using you to get to us. I'm sure you can understand that I want to keep us all safe."
"I do understand. I'm sure I would do the same if I were in your position," you assure her, giving her a warm smile. "There's nothing wrong with being careful. And I promise, I have no intentions of hurting any of you in anyway. In fact, I don't think I have a mean bone in my body!"
She laughs at that, and the atmosphere returns to being light and warm. After making sure all was arranged properly, Toriel heads into the living room to let the others know the food is ready. In a matter of minutes you're holding a plate of various foods and sitting on the couch again. This time Frisk, who is currently talking to a monster child sitting on the other side of her, is to your left and Sans to your right. Everyone is chattering, with the occasional person congratulating Sans and Alphys. You quickly learn that Alphys is the reptilian monster who sticks close to Undyne, and doesn't speak up much. They occupy the love seat, which is opposite the couch you are sitting on. On the floor next to them sits Papyrus and what looks to be a giant calculator. Toriel and Asgore each sit in their own recliners, talking quietly amongst themselves.
Your attention is caught by Sans trying to sneak a cookie off your plate. You smack at his hand, and jokingly scold him. "Hey, you've had enough cookies! Keep your sneaky hands to yourself, bone-boy." He snickers at the nickname before flashing you the skeletal equivalent of puppy dog eyes. You roll your eyes and hand him the cookie while laughing. "You are terrible, do you know that?"
After the meal some of the others decide to play some games. You school Sans in a game of Smash Bros, only to get your butt handed to you by Undyne in the next round. She laughs at you and challenges you to another match. "Oh, it's on now," you grumble, clutching the controller with determination. You still get owned, several more times in fact, but you have a lot of fun. Between that and chatting with Toriel about work, time flies by way too fast. Before you know it she's winding everyone down, and sending Frisk to bed.
After hugging Frisk goodbye, and shaking Toriel's hand again, you walk outside to say goodbye to the others. As you're telling Alphys and Undyne goodbye, you feel a tap on your shoulder. Once you turn around, arms wrap around your middle before you're suddenly lifted off the ground. Papyrus crushes you in a hug while saying; "THANK YOU FOR COMING, (Y/N)! EVEN THOUGH YOU ALSO TELL TERRIBLE PUNS, YOU ARE GOOD COMPANY." You hug Pap back the best you could, but since your arms were pinned to your side you end up patting his back with your hands.
"Bro, don't crush (y/n). I sort of need her in one piece, you know," you hear Sans say somewhere from behind Pap, who "nyehs" softly before lowering you. Once you're placed back on the ground (and Pap moves to the side), Sans walks up to you and throws his arm around your shoulder. "Thanks for coming and hanging out with us monsters. We enjoyed having you here."
You lean into the hug and scoff softly before saying; "C'mon Sans, we both know you only wanted those cookies! Don't try to feed me your sugarcoated lies!" You try to keep your laughter in, but break down once Pap throws his hands in the air and stomps off yelling. Sans snickers while tightening his arm for a second before releasing you. After saying goodbye, he starts to walk after Papyrus. Still smiling to yourself, you turn and make your way to your car.
Unbeknown to you, a hooded figure was retreating further into the shadows angrily tapping at its phone. It raises the device to its ear, and waits a second before speaking in to it. "Yes, I'm through following her. Tell Boss the rumors are true: she's a sympathizer."
