I Wanna Be Yours

Word count: 3,936

Song: I Wanna Be Yours - Arctic Monkeys

/////////////////////////////////////////////////////////////////////////

"Secrets I have held in my heart are harder to hide than I thought. Maybe I just wanna be yours. I wanna be yours."

Flick. Your lighter lights with a simple motion of your thumb. You hold the lit cigarette to your dark colored lips and take a puff. You developed the nasty habit of smoking when you first became a part of the Royal Guard. Being a Guardswomen is tough, considering you actually had a kid fall down into the underground a day ago. You never thought it would happen to be honest, maybe you can finally get out of this hell hole and away from the insufferable assholes that inhabit it. Except for Sans. Sans has been your only escape, your safe haven. You met him through his brother, Papyrus. When you first became a Royal Guardswomen, you met Papyrus and Sans. After having a somewhat awkward conversation with the smaller skeleton, you both hit it off instantly. You two actually share a sentry station near the Ruins.

Both of you share puns and stories with one another. Stories about the good, the bad, and sometimes, the ugly. Sans isn't the most trusting person. It took you a while for him to open up to you about his past. About a year and a half to be exact. Once he told you a bit about his past, you felt so bad for him. Even though he doesn't want pity, you can't help but feel bad. His brother is a very verbally and physically abusive person, especially when things don't go his way. Papyrus usually takes his anger out on someone, and that someone is usually Sans. You want to take him away from this situation. You want him to live an abuse-free life. You want him to be happy. As soon as you leave the underground, you want to take him away with you, if he lets you, of course. But for now, you just have to be there for him when he needs you to be.

"Ay Y/n, you okay?" Sans says, waving his skeletal hand in front of your face. "Uh, yeah, I'm good, I just kinda zoned out." You mumble, taking another drag of your cigarette. Sans looks at you skeptically before returning back to what he was doing. Suddenly Sans turns to you "Ya wanna go to Grillby's?" He asks. "Yeah, I got nothin' else to do." You respond. He takes your hand and teleports into the small diner. You two take a seat at your usual spot at the bar. "I'll take my usual," Sans says to Grillby, you order your f/f. You and Sans just chill and talk while enjoying your meals. After cackling at Sans' story of Papyrus somehow getting his head stuck in a bucket, he goes quiet. You ask him what's wrong. "Can I ask you somethin' Bud?" He asks. "Shoot at me." You reply. "What would you do if you lost the person you love most?" He questions, you're a bit stunned at the serious question.

"I think I'd go crazy. I don't think I could live without the person I love most. Why do you ask?" You question the edgy-looking skeleton. "No reason, I'm just curious 's all." He says, shrugging. You nodd skeptically, you knew he was going to say something else, but then decided against it. After your meal, you realize it's actually pretty late. About six pm, to be exact, both of your sentry shifts ended two hours ago. "Shit! I gotta go, Papyrus is going to crucify me if I'm not back by six. Same time tomorrow, Dollface?" You chuckle, "Same time everyday, Sans," You retort. "I wish he meant to call me Dollface." Wow, that thought came out of nowhere. A blush spreads across your p/f/c (pastel favorite color) cheeks. You and Sans always call each other pet names, platonically, of course. Sighing, you begin walking to your apartment. There was a small apartment complex behind Grillby's that you live in. You used to live in Waterfall, but moved to Snowdin once you got paired with Sans to your sentry station. Even though sentry can change in an instant, you and Sans mostly stay in Snowdin.

Arriving at your apartment, you fish your keys out of your pants pocket. You open the door and sigh a sigh of content. After chucking off your boots near the door, you trudge to your bedroom and change into a pair of black sweatpants and a baggy blue shirt that says "Big Dick Is Back In Town" on it in Times New Roman font. You turn out the lights and collapse on your bed. Within seconds, you're fast asleep. At seven thirty am your alarm rings in your ear. You proceed with your morning routine, you shower, do your hair, put on some makeup, and get dressed. When you go to get dressed, you realise something. "Fuck I forgot to wash my work clothes yesterday!" You groan. You literally have four of the same pairs of pants and shirts you wear for work. You sigh exasperatedly, you have to wear the same ones you did yesterday again. Grabbing your phone, you set a reminder to wash your work clothes tonight at six thirty.

After that, you put on your boots and leave your apartment. Taking a few shortcuts, you arrive at your shared sentry station, cigarette in between your clawed fingers. You sigh, Sans isn't even at the station yet. Anxiously, you wait at the station. About ten minutes later, Sans finally appears at the station, panting and shaking. "Are you okay?" You ask, concerned. "Does it look like I'm fuckin' okay to ya'?" He snaps back. Shocked, you stay silent. You know he doesn't mean to snap at you when he's mad, it's best to give him some space for a bit. You excuse yourself from the station, saying you forgot your phone at your apartment. "Make it quick, I don't want Papyrus to catch you." He says, your breath hitches. Oh, so that's what happened this morning. "I'll be careful, I promise." You reassure, taking a shortcut through the woods to Grillby's. You go in, and order Sans' usual and your f/f to go. As soon as you get the food you leave for the station again. You pop out the same way you entered, right behind the station.

"I'm back." You announce, setting the plastic bag containing food in the front of the sentry station. "Where'd that come from?!" "Uh...Grillby's?" You say, "No-I mean-" sans sighs "I thought you had to go grab your phone from your apartment." He says, you chuckle. "Yeah, I lied. I thought you needed a little pick-me-up, considering the way you came to the station this morning." You explain, tail swishing a bit behind you at the uncomfortable subject. "Oh, well, thank you. I appreciate it, Doll." He says in a sincere manner. You love when he's soft with you when no one is around. In the Underground, it's considered "weak" to show genuine emotion outside of your home. You wish it wasn't like that, but sadly, this is the reality you have to live in for now. For now, you can only be there for Sans when he needs to show his emotions. He can't even show emotions in his own home, Papyrus will be a dick and judge him for it. It's not fair at all.

"Ya alright, Y/n?" Sans asks, pulling out of your thoughts. "Hm? Oh yeah." You respond, now realising how angry you must look. "Yeah, you looked pissed. Is somethin' up?" He asks, you sigh. You knew you'd have to bring this up eventually. "I'm just, so angry at your brother." "Why?" You look down at Sans. "Sans, he treats you like utter garbage! Why do you keep going back to him?" You sigh out exasperatedly. "Because I care about him, even if he doesn't care about me." He says sadly. Your e/c eyes widen. You get it now. He's the only one he has left that's his family. "Sans, I'm sorry. I know Papyrus is your brother, I'm just worried. All the scars he leaves you with. What if he damages you permanently?" You explain, biting on your black claw. Another habit you obtained from joining the Royal Guard. You look at Sans for an answer, you see a gentle red blush spread across his face. "I appreciate you caring Bud, I really do. But I can handle it myself." He says, looking you in the eyes. His red pinpricks aligning with your e/c irises. You sigh and avert your gaze down.

"Okay, if you say so. But if anything ever happens, call me, I'll let you stay with me, okay?" You say, giving Sans your number, witten down on a tiny slip of paper. He says he will. The rest of the day goes off without a hitch. You and Sans finish your shift (on time this time) and part ways until tomorrow. You almost kick your boots off at the door before your phone starts going off. You quickly pull it out of your pants pocket, you sigh in relief. It's just the alarm you set for your laundry. You take your bin full of laundry to the basement of the complex and throw your clothes in one of the cleaner looking machines. As you put your laundry bin down next to the washer, your phone starts to go off. You check and Sans is trying to call you. You immediately answer the call. "Hey dude, what's up?" You say into the speaker. "Y-y/n, could I come over?" You hear his raspy, pained voice through the receiver.

"Yes, of course! Do you need any help? You sound hurt?" You say panicked. "No Dollface, I got it." He says, you do not accept that. "Too bad. I'm coming over anyway." Before he could protest, you hang up the phone and speed out of your apartment complex. Thankfully, Sans' house isn't that far. After a short, speedwalk, you're staring down his front door. You rasp on the wooden door, waiting for a response. You were going to knock again, Sans opens the door, you let out a small gasp. Sans looks terrible, he was covered in his own blood. "Come on, you're staying with me tonight," you say, taking his boney hand. As soon as you start walking, you notice he also has a limp. If Papyrus were some random ass monster and not Sans' brother, you'd be covered in dust by now. You have a very motherly instinct, but only for Sans. You've never felt this way about somebody else before, you have no idea why either.

Once you and Sans reach your apartment, you bring him to your bathroom and seat him on the toilet (lid closed, of course). Grabbing your medical kit and some alcohol, you return to the bathroom and sit on the edge of your tub. "Could you take your sweater off? It'll be easier to clean your wounds." You ask, Sans slowly takes off his crimson red sweater. Suddenly, your bathroom gets really warm. You gasp at Sans' three cracked ribs, a bunch of cuts all over the others. You look up at him with concern written across your p/f/c face. "I don't want to talk about it right now." Sans mumbles, looking down. You take Sans' cheek bones in your hands, you tilt his head up to look at you. "That's okay, I'm just worried about you. You really don't deserve this Sans." You say, pulling your hands away from his face. You pour some alcohol on the washcloth and press it to one of the cuts on his ribs. He curses under his breath as you continue to clean him up. You'll have to call Alphys later about Sans' ribs, see what she can do about them.

"Alright Sans, just chill on my couch for right now. Uh, I gotta go real quick, I'll be right back," you say awkwardly, he gives you a thumbs up. Unlocking your door, you head down to switch your laundry. Once you come back up, you notice Sans wasn't sitting on the couch anymore. You panic and begin looking around your apartment, you stop in the entrance of your tiny kitchen, Sans was making something. "Sans, what are you doing?" You ask, he jumps a bit, then winces. "I'm making us dinner?" Sans says, the room starts to get warm again. "Sans, you don't have to do that. You should sit down and relax." You encourage, he shakes his head at your proposition. "Nah Dollface, this is the least I can do for you." He says, continuing to cook a mysterious food. You come up behind Sans, "Sans please, I appreciate the gesture, but you have three broken ribs, you need to sit down and chill out." Sans sighs "Fineeeeeee." He whines, you chuckle at him. "What were you gonna make anyway?" "Nothin much, just some Spaghetti and meatballs." "Okay, gotcha." You say, taking over the kitchen to make dinner.

Wiping your forehead of sweat, you finished cooking dinner. You walk into the living room, and set his and your plate on the coffee table in front of the couch. You sit next to him and start eating. "Holy fuck Doll, this shit's amazing!" Sans exclaims, shoving more pasta into his mouth. You chuckle and thank him, as you keep eating. After you both are finished eating you run down to the basement one more time to grab your laundry and return to your apartment. On your way. Back to tour apartment however, you notice that Sans has been calling you 'Doll' and 'Dollface' a lot more than he used to. You shrug it off as him being thankful for your hospitality. You return to your apartment for the last time with your laundry basket in your hands. "I'll be right back, I just gotta put away my laundry." You say, Sans looks over the back of the couch at you and gives you a nod of understanding. You quickly fold your clothes so Sans doesn't have to wait awkwardly on your couch. As soon as you're done, you put the basket in your closet and leave. When you return to your living room, you discover Sans asleep on the couch.

A small smile forms on your face as you go get him a blanket. After that, you change into a red tye-dye pair of sweatpants and a tank top. Soon after you lay down, you drift into a deep slumber. A few hours later, you are ripped from your sleep by a scream. You pull off your blanket and run to the living room. "Sans?!" You say worriedly and panicked. You see him tossing and turning on the couch, he's having a nightmare. Sans has told you about these haunting nightmares before, it usually happens after a bad day with Papyrus. Not really knowing how to deal with this situation, you sit on the edge of the couch and try to reach for him. As soon as your hand makes contact with his shoulder, he pulls away and curls up into a tiny ball. "Sans, it's just me." You say gently, scooting a bit closer to his trembling and sobbing form. You try to comfort him again, and he doesn't pull away this time. You pull him a bit closer to you. He rests his head on your chest and clenches his arms around you. You massage his skull with your fingertips and whisper sweet nothings to him.

After a while of comforting him, he falls asleep again. So you lay on the couch, Sans' head resting on top of you, blanket draped over your two sleeping bodies. After a few minutes, you fall back to sleep. You awake to one of Mettaton's shows. You were never interested in the performer robot that much, but this episode was a (what looks to be) a well made CGI human defusing a bunch of bombs. After a while, you forget about Sans laying on your chest, until he wakes up and jumps off of you like a startled cat. "Jesus! Just scare the shit outta me why don't ya?" You say, sarcasm lacing your tone. "Ah, sorry 'bout that Doll." "You're fine Sans." You chuckle. Looking up at Sans, you notice a light red blush across his cheekbones. Your heart skips a beat as you look at him, then you get up not wanting to make this any more awkward than it already is. Opening the fridge, you look for something to eat. You have eggs, bacon, and pancake mix in one of your cupboards, you take out all the ingredients you need for breakfast and start cooking. Sans insists on helping, but you tell him he needs to to relax because of his broken ribs.

After a half hour, breakfast is completely done. You fix you and Sans a plate and bring it to the couch. Sans looks very fixated on Mettaton's show. This was a rerun of a previous show. You set the breakfast down in front him, he immediately begins choking down food. "Holy shit Sans! Slow down your going to choke." You scold. "But we're gonna be late to work if we don't." He explains, scarfing down his meal. You give him a confused look. "Work? We're not going to work today, we have to call Alphys over to see what she can do about your ribs." You say, you can feel Sans look at you like you had just told him you had a death wish. "I can't, Papyrus would freak out-" "Papyrus can suck my dick!" You cut him off out of anger. "Your health is WAY more important to me than what Papyrus might do." You snap, Sans sits in shock. You've never snapped at him like that before. Looking at his face, you realise what you just did. "Sans I'm sorry. I didn't mean to snap at you like that, I just got to frustrated." You explain, Sans' face softens at your words. "Nah it's okay, I completely understand where you're coming from." Sans sighs, and rubs the back of his neck anxiously.

To defuse the thick tension, you tell Sans you have to call Alphys and you'll be back shortly. You shuffle awkwardly to your room to make the call. Pressing the contact "Weeb Lord'' with a picture you took off of Alphys' social media (it's a picture of a trash can with several red sparkly filters over it) and press the call button. "Yo Alphys" "What is it Y/n?" She says annoyedly. "So, I need you to come over to look at Sans' ribs." You say, "What? Why?" "Papyrus and him got into it yesterday and he's staying with me for a while." You explain, Alphys makes a noise of understanding from the receiver. "Alright, I'll be over in 10." She says, you can hear her shuffling around. "'Ight see you when you get here." You end, hanging up the phone, not really wanting to go back out and just awkwardly sit with Sans, you decide to have a smoke. Grabbing you cigarettes and lighter, you begin to head out of your apartment. "Where are ya going?" Sans asks, still staring at the T.v. "I'm just going to have a smoke, I'll be back soon." You reassure yourself as you leave the apartment. Maybe taking a smoke wasn't such a good idea. It's cold as balls outside, you shiver as you take drags of your cigarette.

After you're done, you are about to go inside, but a certain nerdy lizard shows up. She follows you up to your apartment and in through the front door. "Ay look what the cat dragged in." Sans teases, Alphys glares at him. "Nah I'm just joking with ya, how've you been?" "Okay, yourself?" She asks back, Sans shrugs. "Eh, could be better." "Yeah, I heard. Would you mind taking your sweater off for me?" She asks, he reluctantly takes off his sweater again. Alphys studies the three cracked ribs for a second. "Hmmm. I think the best I can do for you is to wrap you up. Other than that, there's nothing I can do." She explains, beginning to wrap Sans' ribs. "You'll have to not go to work for a few days, take it easy. No lifting, no fast movements, nothing." She drones on. "Your best option is to stay with Y/n for now so they can help you heal properly." She states, finishing up wrapping Sans' ribs.

You let out a relieved breath you didn't even know you were holding. You had hoped that Alphys would tell him to stay with you, Papyrus would probably just hurt him more in all honesty. "I'm going to give you some morphine to help ease the pain a bit." She says, handing Sans an orange pill bottle. "Take two when you wake up, and when you go to bed, if you notice the pain going away, then only take one per day." She explains. You and Sans both nod. "Thank you, Dr. Alphys." you say, Alphys nods. She takes her tote bag full of medical equipment, bids you and Sans goodbye, then leaves. You sigh, and sit next to Sans on the couch. You begin to think, why do you feel so nervous around him all of a sudden. Your heart skips a beat whenever he calls you "Doll" or "Dollface", his laugh gives you butterflies, you want him to talk to you forever, just listening to his New York accent makes you want to kiss him. You can't take hiding your feelings from him anymore, you have an undying love for Sans.

"S-sans, I gotta tell you something." You stutter out, Sans turns to you. "Yeah, what is it Dollface?" He asks, your heart beats faster and faster every passing second. "I think I wanna be yours, Sans." You manage to get out. As soon as those words leave your mouth, you regret everything. "Y/n, I...I think I wanna be yours too." Sans mumbles, scooching a bit closer to you. You move closer and closer to each other until your thighs are squished together. Sans cups your cheek with his hand, you place one hand on his shoulder and the other behind him. Sans sets his other hand on your thigh, you lean in and give him a smooch on his sharp teeth. You pull away before Sans' hand moves from your cheek to the back of your neck, pulling you into a more passionate kiss. The passionate kiss turns into a makeout session. Both of your mouths moving in sync, tongues sliding over each other, soft moans come from both of your mouths.

After a minute of missing, you two pull away, a string of clear and translucent red saliva connecting to your mouths. "Oh my god....that was amazing." You pant, leaning back into the couch. Sans nods his head in agreement. "I'm so glad you confessed to me, Sweetheart. I've had feelings for you since we were stationed at our sentry station together." Sans explains, your heart skips a beat at your new nickname. You blush. "I'm so glad I met you." You say, leaning your head on his shoulder. "Same here Doll." Sans responds, leaning his skull on your head. You're both finally safe and happy.
