Not like them ~ A Sans x Reader ~

-One week later-

~Still Y/n's POV~

I still haven't gone to the store yet, I'm too embarrassed to be seen buying pregnancy tests. I laid next to Sans on his bed, I was late for my period which didn't help my nerves. What if I was pregnant? How would Sans react? Would he leave me? I tried to push the thoughts out of my mind, he wouldn't leave me... Right? I guess we'll see here soon. I got out of bed luckily not waking up Sans, I changed into some different clothes and headed out to the nearest store.

-A few minutes later-

[At Wal-Mart]

I looked at each pregnancy test, I wasn't sure which one to get. I kept on turning my head to look behind me in case somebody I knew saw me looking around at these. I was too busy debating between 2 tests that I didn't hear the footsteps behind me, before I could realize somebody spoke to me in an all too familiar voice.

"Y/n?" They asked

Oh god no.

Of all people I could run into it had to be her.

"U-Uh." I responded and slowly turned to face my sister. She gasped when she saw me. "Why did you run away from home?!" She nearly yelled. "None of your business and keep it down, will ya?" I said while giving her a glare. "Well I'll make it my business." She snapped back at me. "Fine. I got sick of everybody's hatred towards monsters." I answered. She looked like I had just said the worst possible word in the entire galaxy. "But, they're awful!" She tried to reason. "We miss you Y/n." She said sweetly. "I thought you just said monsters were awful and now your telling me you miss one of them?" I questioned letting my secret slip, she looked at me in confusion. "But... You're not a monster." She said. "Yes. Yes I am, I'm also dating one and might possibly be having a child with him." I replied, rage coating my voice. She gasped, her eyes then turned to utter disgust. "You sicken me." She insulted, as if it work. "That's the best thing I've heard come out of your stupid human mouth. Now leave me alone before I show you my monster abilities." I replied while giving her a death glare, but she did what I thought she would never do.

She freaking slapped me.

I held my cheek in pain, I then felt something burning within me. I sneakily looked up and saw security cameras watching the whole thing, I smirked. I then turned back to her. "Do that again, I dare you." I challenged. She complied and slapped me harder than before, she kept on slapping me until finally I was on the ground. "I am not related to a monster!" She exclaimed, some people noticed this and started to walk over to where we are. They all gasped at the sight they saw, then staff workers started coming. "What happened here?" One of them asked. I just groaned in pain, she could actually slap pretty hard. "I was just using self-defense! This girl right here tried to attack me!" My sister lied. The staff then looked at me, I looked at them. "Look at the security footage." I told them while nodding my head toward the camera. One of them left to go see while the other stayed there to make sure none of us got away. I looked to my sister, I was still on the floor in pain but I managed. A smirk came up on my face when I saw the horror in her eyes, she was so busted. The worker that looked over the footage came back. "She's lying." They said while pointing towards my sister. They nodded and called the cops, I got back up still holding my cheek in pain. "May I asked why she attacked you?" A female worker asked me. "Well, she despises monsters. I'm actually her sister and when I told her I was a monster and was dating one she snapped." I answered. "You're a monster?" She questioned looking me up and down for any unusual body parts. "Yep. I know I don't look it but I have the power to summon objects out of thin air." I replied. "That sounds so cool!" She excitedly exclaimed. I giggled at her reaction. The cops eventually came and took my sister away, and I finally decided to buy a reliable looking test.

 -A few minutes later-

I finally arrived home with a sigh of relief as I shut the door. Sans teleported in front of me suddenly and pulled me into a sweet embrace. "Where'd you go?" He questioned not letting go of me, I had hugged back at this point as well. "I went to buy a..." I trailed off thinking of how this could go wrong. "A what?" He asked. I swallowed the lump in my throat, I shouldn't be nervous about telling me. "Pregnancy test." I practically whispered. Surprisingly he didn't flinch or tense up in fact he hugged me a little tighter, but not too tight. "Just know I won't leave you, I'd be a numskull if I did that." He said, I instantly snorted as I let out some small giggles. We eventually broke the hug and I reached into my Wal-mart back for the pregnancy test box. "Sooner or later?" I asked Sans. "I think sooner." He said with a grin. I nodded in agreement and went into the bathroom to take the test.

-Once again a few minutes later-

I looked down at the test, everything seemed to stop around me as I stared down at the result. "S-Sans!" I cried out not looking away from the test. He opened the door, my back was facing him and he couldn't see the results yet. "So?" He asked excitedly, I turned towards him still not letting him see it. A grin then crept onto my face as I let the result sink in, tears started to flow from my eyes. I looked up at Sans with a stupid smile, he looked at me anxiously. "I'm pregnant." I breathed out, his face instantly lit up with joy as he picked me off the ground by the waist and spun me around. "Sans!" I exclaimed through my giggles. He then let me down and kissed me passionately. "I love you." He told me, for some reason this made me feel so much better. "I love you too." I said as we kissed again.

Wait until Alphys hears...
