Demons Love [Underfell Sans x Demon-Reader]

Confessions

Your POV

I was on my way searching for a soul for the contract I made for the date.  All I need to do is kill someone, take their soul, and bring it back to hell.  It sounds simple, but it's actually pretty much difficult to kill someone without getting caught.   I went deep in the forest to look for some homeless guy to kill because their pretty easy to fight.  Not much luck.  Luckily there was a bunch of hunters who were searching for animals to hunt, they were all separated too which makes  my job easier.  I spotted a hunter far from all the others.  Just glike t to do this quick and easy.  I flew towards a tree that he was near and waited for the perfect moment to attack.  He heard the rustling I caused and looked around with his rifle in his hands.  He turned his back to me, then I jumped from my hiding spot and attacked.  Killing him was easy, just tear their skin a couple of times then rip off one of their limbs.  His soul slowly rose from his corpse.  I carefully took it and his body parts with me to hell.  

As I entered hell, there wasn't much cake going around as usual.  Everybody was probably eating lunch or something.  I left the body and its body parts on the floor and went to the Castle were I can give the soul.  The library was open and my contract was in the same place I left it.  The contract was in a glass container so nobody can do anything to it, I placed the would in the container with it and a beam of light shined from the container.  When I looked back, the container was gone which means that the contract was finished.  "That was pretty easy"  I'm sure another contract wouldn't hurt.  "That one over there"  The voice in my head directed me.  I looked in the direction she said.  I black scroll was on top a pile of other ones.  How did I  or notice that!?    The contracts allows me to love without the consequences of a demon for life.  But I can't pay any soul, I need to give a soul of someone that is really close.  "Fuck no"  There is no damn way I am doing that!  Maybe I'll come back later.

TIME SKIP

Turns out that guy I killed was the Mayor's son.  Shit...  why was he hunting in the first place!?  Cops are sending out a search party in he forest, but something tells me that they won't find him, or any of his body parts.  Hehe.  I'm probably gonna become a wanted criminal soon.  "So where were you an hour ago!?"  Amy asked from the kitchen.  "Bird watching"  I replied from the living room.  She didn't protest and continued cooking.  TIME TO DAY DREAM.  Yesterday was the best day of my life!  It was our first kiss!!!  I was screaming internally at the moment.  It was hard to believe that he kissed me.  But hay!  It was a kiss and that is all I care about right now!!    "You ok!?"  Amy snapped me back to reality.  "Yes!  I'm wonderful!!!" Yayayayayay!!!!  It's hard to get controll of my happiness right now.  "WHAT DID YOU DO WHILE I WAS GO E YESTERDAY!?"  Amy didn't sound to pleased, she sounded like I did a crime while I she was gone yesterday, but I did that today.  "Nothing!..."  I'm not very good at lying.

Amy jumped on me and inspected my face.  It wasn't creeping me out because of my own logic.  When girls are creepy it's normal, but when guys are creepy it's....creeeeepy.   "Tell me every single detail!"  I was in trouble.

After the interrogation!!!!

" I CANT BELEIVE YOU!?"   "

"Ok"

I told her about the kiss, the contract, and how I became a wanted criminal for killing the Mayor's son.  She didn't take it in very well.  After she flipped the coffee table, she went upstairs and screamed.  Normally people would scream in their pillows,  but....not for her.

Sans POV

It was 12pm and I just woke up from a nap.  "SANS!  WHAT WERE YOU DOING YESTERDAY!?"  "Nothing much! Why?!"   "AMY IS ASKING WHERE YOU WERE AT LAST NIGHT!"  Shit.   It's either somebody was spying on me and Y/N last night, or Amy was able to get Y/N to talk.  Both of those could actually happen.  "Tell her I was sleeping!"   "SHE ISNT GOING TO  BUY THAT AND NEITHER AM I!"   "I speak the truth!"  I said sarcastically "AND SO DOES Y/N!"  Shit, so she did say something.  Paps walked up to me and showed me his phone.  There was a video of Y/N confessing absolutely everything while being tied up to a chair in their kitchen.  "SANS!  IS IT TRUE YOU WENT ON A DATE!?!?"  "Maybe..."  I mumbled quietly.  "WELL THEN!  LEAVE ME OUT OF IT!"  He walked away to his room and left me.  I expected worse, but I guess he didn't really give a crap about my personal life.  Lets see how Y/N is holding up.  

I teleported to her house and the first thing I heard was screaming.  I looked around for Y/N,  she was still in the kitchen...tied up in the chair....surrounded by a bunch of broken items.  To my surprise, she was sleeping.  It didn't look like a very comfortable position to be sleeping in, so I untied her and took her to her room.  She was heavy, but I could handle.  While going to her room, I tried  it to get caught by Amy.  I placed Y/N on her bed where she lay asleep.  There wasn't much to do, so I looked around her room.  Of course she had a diary in abbot so guarded chest that was in her closet.

I'm pretty sure she won't mind me reading it.  

Page 1:  

Dear Diary,

Moving here was the best Idea ever!  New house, new friends, and new....stuff!  I can't believe Amy was friends with all these amazing monsters!

The first page was all about her first day here.  She has a lot of enthusiasm in her writing.  I flipped through more pages and saw one called not a dream.  It looked long...but why not read it.

 Not a Dream

JUST CAME BACK FROM A DATE WITH SANS!!!!!!  HELP ME I CANT BREATHE!!!  It was so magical, I felt like a dream.... A dream come true baby!! !   It's really complicated to take it all in right now!!  I can't stop thinking about that kiss....  it's very hard to believe that somebody in this world actually like likes me!

It went on and on.  She had  pretty tough past.  She also told me about that contract, but she never told me about taking somebody's soul.  The next page was all about her killing someone.  So she was the person who killed the Mayor's son.  It turns out that she teared him limb from limb.  Her diary should become an actual book.  I read all about her travel to hell and about another contract she decided not to take.  She has all these ingesting secrets.

"-yawn-  Sans?  Is that yo-  WHAT ARE YOU DOING!?"  Y/N woke up and she jumped on me, she grabbed her diary out my hands and hid in her closet.  "WHY DID YOU TAKE MY DIARY!?"  She yelled from the closet.  "I thought it was a book"   "Liar!"  I heard her sniffling in her closet now.  I opened the door and saw her in the corner crying.  Shit, now I gotta comfort her.  "Nobody is suppose to look in here!"  "Look...I'm sorry for reading it"  I sat down next to her and placed my hand on her shoulder.  "How much did you read?"  She was more calm this time.  "The whole thing..."  I softly said.  "ARE YOU KIDDING ME SANS!?"  Welp...she wasn't calm for long.  My hand on her shoulder started to burn, it felt like I was touching fire.  "HOW COULD YOU DO THAT!?  DONT YOU KNOW THIS IS MY PRIVATE BOOK!?!  IM GONNA KI-"  She paused her sentence and curled into a ball on the ground. "Sorry"  she whispered.  I guess it was kinda my fault....  I did just learn most of her life  by now.  I sat sat down next to her again and grabbed her hands.  "Nah, it's my fault princess."  She gave me one of her death glares and looked away, but she didn't let go of my hands.

We stayed there for a while.  It made me realize what a big closet she has.  "So you read all the pages in my diary?"  I nodded.  She burried her face in embarrassment.  "At least I have someone else to talk to..."  She looked up and sat next to me, still not letting go of my hands.  "I only had this diary to share my feelings with because books don't talk back."  The moment was getting cheesy, but I did t want to move.  She laid her head on my shoulder and I moved my arm so it was around her waist.  My other hand was still holding hers.  We stayed like that for a long time.  Next thing you know, we fell asleep in each other's arms.
