Undertale: One Shots! [REQUESTS INFO ON LAST CHAPTER]

Psycho!Sans X Reader (Part 2)

I mustered all my strength and reached a phone that was lying on a desk nearby. I dialed 911 in hopes they would come fast. I wanted to get back at them...and fast.

I would get them back later tonight...

That much I was sure of.

As of today....I am no longer (Y/N)'s friend, but an enemy.

-

I opened the door to my house. Luckily, I had cleaned it right before he came! Sans took his time looking around the place, nodding to himself as he plopped down onto the couch and asserted himself.

"Nice place you've got here!" He exclaimed. I blushed at the compliment and shrugged it off. "Well, you can stay here till all of that's gone to pass..."

"What do you mean, 'gone to pass'?"

I was caught off guard by his sudden change in tone. I gave him a questionable look... "Uh, you know, till everything over the murder calms down and such. Then we can go back to our normal lives." I explained.

"..."
"..."
"...pfft."

Slowly, Sans began to laugh again, each one getting crazier. Then he looked at me with a funny face, and grinned. "None of this is going to pass! I killed for a reason you know. I plan to go through with all this. I thought you were going to join me...but...I guess not." He sighed, standing up and walking straight past me, without another glance.

"Wait! I-I can help you!" I said suddenly. I wanted some excitement, right? That's what I signed up for, right? Really, it was just the fear of going back to my old life that scared me so gravely...

"Hm~? Aha! I knew you would say that." He laughed and leaned in, giving me a kiss. "Mwah!"

I blushed and backed away from him, now a bit wary of what exactly I had signed up for. "Wha–?" I felt something, like a pill in my mouth, and accidentally swallowed it...

"No time for questions now! I have somewhere to be. I spent some time setting up a special...game, for me to play. Buuut~ if you want to be my partner in crime..." He snickered, heading out the door. "You can come with me to play it~?"

I gulped, and knew what I was doing was crazy...I knew HE was crazy. But I had gone too deep down the rabbit hole to back out now. So I grabbed his hand, and together we raced down the street, dead straight on towards my school. "There it is~!" He chirped, going over to a fence right next to the school and heaving himself over it.

"Eh..?" I asked and struggled to get over the fence. "Why are we here at my school?" I asked, following his tracks towards a shed. "And why so late at night?"

"I already told you, I have a game planned for us." Sans arrived at the door of the shed, and opened it carefully. "Wanna take a look?" He asked.

My heart was pounding...every one of my senses told me to run away now. I knew it was my final chance. Everything screamed at me not to do what he said, not to fall into his trap. But as I began to back away, I felt something tell me to go forward.

Something was...making me not think right. What was it? I couldn't think right, and I began almost sleep walking into the shed, where I saw a horrible sight...

Three students, who I was all friends with, we're all tied up back to back, fear shining through their eyes, I cried out in fear, and began to run away. But I didn't get far. I tripped over a rock and scraped both my knees and elbows on the cement. I wailed in pain, struggling to get to my feet, when I noticed Sans hovering above me.

"My my...you wanted excitement, right? Trust me, this is only the hardest part. After this is where the fun comes in~!" He sighed, pulling out his knife and holding it out towards me. I just stared at it...

"You can either kill, or end up like your friends. Doesn't matter to me. I tried to be partners with these three as well, but both tried to run and well...now their here. So I used something different on you." He said with a laugh.

I touched my lips. "Was it..?!"

"Yeah, that pill. It's supposed to make you crave excitement, and most of all crave killing. But maybe it didn't work...?" Sans asked, still holding out the knife to me. "So what do you say?"

--

I'm going to get (Y/N), tonight! I just tracked her phone and found out their at the school right now. Hopefully, with Sans as well. I had patched myself up and ran towards the school without a second thought, gun in my hand.

As I got there, I noticed a shed door opened behind the fence. It's like their not even trying to hide. Too bad for them.

I jumped over the fence and looked into the shed, expecting to see them, but....only finding a phone on the ground next to three dead bodies.

"No way!" I shouted angrily. They had tricked me! I sighed and walked into the shed, examining the three dead bodies, feeling sad I couldn't save them, when...

"ARG-!" I cried out in pain, as blood gushed out of my arm. Someone stabbed me!

I grunted in pain, turning my head to see...

"(Y/N)...? What...? Why...?" I asked in fear, noticing Sans was right behind them. They laughed crazily together, especially (Y/N).

"You wanna know why?" (Y/N) asked, insanity swirling in their eyes.

They lifted the knife up high, and I put my arm up to shield myself from the attack even though I knew it would do no good.

"Because I'm tired of every little perfect thing in my life. This is way more fun~"

The knife sliced down, and all you could hear was my own scream.

(( RUSHED ENDING but I actually liked this story! I tried to give it the effect I wanted it to have on the reader but idk if I actually accomplished that. Sorry for not updating in a while!! Hopefully this makes up for it!!))
