Undertale AU x Reader (Requests welcome)

New Faces, New Friends.

No lemons today, heh.
I got a fluff for you guys.
With my little smol.
AsylumTale! Sans x Insane! Reader, meaning you and Sans are stuck in a room together, Sans being there for his whole life ever since Papy died and you, there for only a couple years, 3-5 to be exact, why? Because you mentally snapped and killed off your whole family and neighbors, you have voices in your head, you think they are real and they make you believe in 'resets'. So anyway yeah.

your nickname in this is button, dont ask.

ANYWAY, LETS GET TO IT.

Sans Pov:

It's really quiet today...A bit too quiet..Wait..Where's Papy? Where did he go??

I began to freak out as I clawed at my skull, making more scratches. I was mumbling to myself, where could he have gone?? We are trapped in this room together! "PAPYRUS! WHERE? WHERE ARE YOU?" I screamed, light green tears treaming down my face. That's when I heard Toriel's voice, I looked up and saw her with a worried expression, I smiled softly and ran to the glass, "T-Tori! I-I...I can't find Papy!!" I yelled through the glass to make sure she heard me, she sighed and took out the keys to my room and came inside. "Sans...We need you to calm down. I'm sure....Papyrus...Will come back momentarily, but for now, we need to care for your new scratches." She reached a hand out to me, I looked to her hand and back to her. I nodded slowly and took her hand, she pulled me close and pulled out some colorful band-aids...hehe, I like these ones. "You like the new colors?" She held them infront of my face and I nodded vigorously, leaning my skull down so she could bandage up my scratch marks. She chuckled and unwrapped the bandages and placed them on the wounds. "Thanks Toriel! I feel better now!" I squealed as I reached my hands up to my skull and pat on it, a big smile tugging at my teeth. That's when I felt a hand on my shoulder, I looked to it and followed the hand to behind me, it....It's PAPY!!

Tears once again forming in my eye sockets, I turned around and instantly hugged him, confusing Toriel in the process but she shrugged it off. "Seems like Papyrus came back huh?" I nodded and held onto tightly to him as she left the room. "Papy! Where did you go??" I released him and looked up to my brother, "I was just looking around, and I have some wonderful news for you Sans." His smile widened and my eyes sparkled as I jumped in excitement, "Tell me tell me tell me tell me teLL ME TELL ME!" Papyrus covered my mouth and I giggled, he slowly uncovered my mouth and crossed his arms. "Seems like you will be having a new buddy, they will be living in this room with you. Isn't THAT just exciting?" My face beamed and my eyes were shaped like stars by now, a new face? NEW FRIENDS? "Really?? I want to meet them now!! Who is it??" I was skipping around and squealing, this is exciting!!

(Y/N) Pov:

God, it's been 5 years now, stuck in this miserable hell hole. But, I guess it isn't too bad, because I had a friend, Sans and his brother Papyrus, Papyrus was see through really, meaning he was a ghost, he was a really nice ghost though! Better than the damn voices in my head. The voices appeared when I was around 8, telling me about the resets, flashbacks of monsters dying, their dust in my hands, now I'm 17 and they have gotten worse. I was 12 when I killed off my family and witnesses, the voices told me too, they wouldn't leave me alone about killing them so what other choice did I have? To be honest? It never phased me, my parents were the worst, they beaten me, blamed everything on me, and even stabbed me. But my siblings, that, is the one thing I regret, they only helped me through it all...ARGH! I have no time for this!!

It was feeding time, and Toriel brought us our trays. Same as usual, soup, mashed potatos, pb&j, and milk, I know they slip pills into the food, so I always avoided eating, but hell I was starving so I ate it this one time. I was finished faster than ever, Sans was surprised and finished not to long after me, Tori opened the small opening and took the trays, leaving us alone once more. I let out a sigh and felt a bit dizzy, damn pills, I held my head and brought my knees to my chest, "Hey, button? What's wrong?" Sans crawled over to my shaking form and tilted his head to see my face, I sighed softly and nodded slowly as the dizziness faded, "Yeah Sansy, I'm fine. I was just a bit dizzy is all." I gave him a reassuring smile, Sans was older than me by a whole 2 years but was still shorter than me, so I would always tease him. He nodded and stood up, reaching his covered hand out to me, I took his hand and he pulled me up. My legs turned to jelly and my body collapsed onto his, he stumbled backwards but stayed standing, he held onto me, "I don't think you're ok (y/n)." I nodded as he picked me up and laid me down on the bed that was glued to the middle of the floor of the plain room. I whined and curled into a ball as the sickness crawled to my stomach, what the fuck did they do to my food? "(Y-Y/n)? I-I think your sick, Papy we n-need to help!" He turned towards his brother and Papyrus nodded. He went to the other side of me and placed his hand on my forehead, his bone brows furrowed as he pulled his hand back, "She doesn't have a fever...It's probably what they did to the food brother, call for help." Sans began to tear up and nodded, he quickly stood up and ran to the glass, screaming and banging on the glass for help. Papyrus pulled the blankets over me, he rubbed my head and back to help distract myseld from the pain, I groaned and pushed myself against his touch. Not soon after, Alphys ran into the room with Sans next to her side, "A-Alright, let's see w-what is the m-m-matter.." Her usual stutter pulled me from my daze as she felt my forehead, no fever like Papy had said, she sighed and studied all my symptoms.

{|A couple hours later|}

"Al-Alright, she will b-be better soon." Alphys sighed, wiping her forehead from sweat, I smiled weakly as I curled into the covers, "Thanks Alphys!" Sans quickly hugged Alphys before she left, Sans crawled onto the mattress and snuggled up next to me, Papyrus next to us both. "Sans, you shouldn't be cuddling with me.." My voice was raspy, I cleared ny throat and tried to push him away, he only tightened his grip as he laid his head on my breasts, I sighed and just gave up. Wrapping my arm around the small skeleton, "I love you Sans.." I mumbled, and stared into the white ceiling, "I love you too my little button!" His cheery voice made me stiffen and a deep blush to creep onto my face, Papyrus chuckled and kissed the top of our foreheads. "I love you Papy.." I smiled softly and he nodded, heading over to a corner and watching us drift off to sleep. This is as close to a family and soon to be boyfriend, I will ever get..
