Not All Monsters are Bad (UF! Sans x Experimented! Reader)

~A Stalker?~

???? P.O.V

Heh... She still believe that her big bro is still good I could just laugh at her stupidity "This human is really something..." I thought to myself while following her.

You could call me her stalker but I'm doing this because there's something special about her like I've known her since the beginning of this whole crap.

She met a few monsters on the way but all she did was gave them 'MERCY' this girl won't fight them or anything to harm them she just gave them the 'MERCY' crap she will die if she keeps doing this....

But....

Why am I concerned about her? I don't know her that well and all her stories.... 

But....

Still she made my heart skip a beat like it never beat before every time I followed her, every step I take closer to her my heart beats like crazy like I'm having a heart attack.

Am...

I..

Falling...

In Love....

With a Human...?

Nah I won't but still why am I following her? Oh God it's getting late I have to go home before he beats the living sh*t out of me.

Your P.O.V

I have a feeling that someone was watching us I scout the area and saw no one Flowey looked at me confused.

"What are you doing?" He said and tilted his flower head.

"I thought someone was watching us but I guess it's just my imagination." I said and continued walking.

Flowey seemed to be active along the way he always check side by side non-stop and now I feel exhausted by walking for it seems like hours I looked at Flowey but he seems really active.

"Flowey can I take a nap for an hour or two?" I said.

"Of course you can Y/n no need to ask permission just sleep for tonight and I'll just stay up late to alarm you if a monster comes by okay?" He said.

"Good night Flowey" I said and kissed one of his petals he blushed.

"Good night too Y/n" He said I smiled and closed my eyes drifting myself to sleep.

~Nightmare~

"B-brother I-it h-hurts!!!" I said wincing in pain.

"It will be over soon Y/n..." He said I screamed in pain while he just stared at me smiling like a madman.

"BROTHER!!!" I said one last time and blacked out....

I woke up on a bed my hands being cuffed on the side of it and my mouth being shut by a cloth I tried to move but fail someone opened the door Infront of me and it revealed my brother he was holding a syringe I tried to move again but he just walked over to me and grabbed me in the throat I can't breath I just choked and he injected the syringe in my arm I screamed but it came out as a muffled.

"Don't worry sis it's ok the pain will be over soon" he said with a chuckle.

I was crying from the pain and he just chuckled at my sobs.

"Oh~ Y/n  did you really think that I'm the same brother that you've grown to love? Ha! Pathetic! You always believed that there's always good in everyone" he said.

"and that makes me sick!" He said disgustingly.

"But.... I love it to see you try and suffer in the end you'll just die and realize that you've been really good to them and they're the ones that will kill you slowly~ oh I wish the day will come~ So I can see you suffer~" he said and laughed maniacally he took off the cloth in my mouth.

"But... I still forgive you brother!" I said he just looked at me and stopped what he was doing.

"How?" He said in disbelief.

"I know that your still the brother that I know and loved your always there when I need you in the darkness of times...." I said he continued what he was doing and pressed the syringe harder in my arm I screamed-

~End of Nightmare~

I woke up from Flowey shaking me uncontrollably wait... He said he will wake me up if a monster comes by that means...

I shot back to my feet but stumbled back to the ground with a loud 'thump' but it was wood on the ground and not dirt I looked at Flowey and he seemed to be surprised as well I was sleeping on a couch I looked around and I was in a house.

"Flowey how did we get here?" I asked him questionably.

"I don't know but all I know was we were outside then I fell.... asleep" he said embarrassed.

"It's ok if you sleep but why are we in here?" I said confused.

"Maybe a monster picked you up and brought you here?" He said confused as well.

Just then the door swung open revealing a tall skeleton.

"AHH I SEE THE HUMAN IS AWAKE!!! TRASH BAG COME HERE!!!" He said and a small skeleton came in and it was the monster that shocked me and Flowey before.

"W-what is I-it br- I-I MEAN BOSS!!" He said nervously the taller skeleton smacks his head hard.

"DON'T CALL ME 'BRO' YOU PATHETIC EXCUSE FOR A BROTHER" The taller one said angrily.

"BY THE WAY MY NAME IS THE GREAT PAPYRUS AND THIS IS MY PATHETIC BROTHER SANS!!!" He said angrily and pointed to his brother Sans who waved his hand.

"WHAT'S YOUR NAME HUMAN!?!" He said shouting.

"I'm Y/n!" I said they seemed surprised?

"WHY AREN'T YOU SCARED HUMAN?!?!" Papyrus said

"I've met many monsters here in the underground they all seemed really nice!" I said the both of them just laughed at my reason.

"What's so funny about it?" I said.

"YOU THINK MONSTERS ARE NICE!?!? HA!" Papyrus said looking at me in disbelief I nod my head 'yes' and they both stopped.

"Hey human are you really sure about that?" Sans said his red pupils gone only darkness in his eye socket.

"Yes! I'm positive about it!" I said Flowey just shake his head 'no' to me.
