I Need Someone Too (Underfell!Sans x Demon!Reader)

Meeting the Feared Skeleton Brothers (3)

//just thought that video matched this story, doesn't affect the story//

I stepped into the cold climate and the snow crunched beneath my feet. The wind hit my face and body while I stood there, takeing in in in a stinging breath. I urged myself forward knowing I had a mission to do. After a few minutes trudging through the deep snow I saw a large branch. "...I bet I could break that. So at that I put my weight on the branch, making it splinter and snap. Just after that step I hear a man yelling.
"SANS YOU HAVEN'T RECALIBRATED YOUR PUZZLES! WHAT IF A HUMAN COMES AROUND!" as I look up a see figures about 30ft away. One the taller one, though even the shorter one had at least 2 feet in me, was the one making the racket. I feel the urge to hide but I don't. I could win a fight with them if I got in one right?

I continue walking, I go to walk past them when the shorter figure who I see now is a skeleton, says "hey, you, I've never seen you 'round here before." Which prompted who I assume is his brother to say
"YES, GIRL, WHAT US YOUR NAME! WHO ARE YOU?"
I sighed and said "Hello, my name is (y/n)"
"WHERE DID YOU COME FROM, THE UNDERGROUND IS QUITE SMALL AND I HAVEN'T SEEN YOU BEFORE!"
"Yes I fell."
"But kid, you're a monster"
"Really I hadn't realized."
"(Y/N)DO NOT SPEAK LIKE THAT TO MY BROTHER"
I was starting to get a little pissy now, this was none of their business! And they had the nerve to tell me what to do?! "What're you going to do about it bone head." I challenged Sans's eye faintly glowed red and I could feel power eminating from him but, I didn't care. "Are you going to kill me! Oh no I better stop its just, my mouth seems to have a mind of its own!"
"Kid you don't wanna do this." Sans threatened.
"Don't tell me what I do and don't want to do," I said with a sarcastic smile
"(Y/N) I CHALLENGE YOU TO A DUEL"
"Okay sir dumbass get ready to have your ass handed to you." Sans stepped back looking a little bit worried. I stepped towards the skeleton and put my hand out, firing boiling water at him with enough force to knock him at least eight feet back. He stood after a second, looking a bit less confident then before and fired a bunch of sharpened bones at me, but I dodged all of them. Both skeletons looked a little bit scared but the one I was fighting smirked then summoned a giant dog/dragon/wolf skull. He moved his hand down and the skulls mouth opened allowing a huge beam of light to fire at me. As soon as I felt it, I calmed down. This, was a fire blast and I'm pretty fire resestant from the account of, I'm a demon, who lives in hell, which is basically a fire pit. The blast finally stopped and I was in the middle of a circle of melted snow. The skeletons both stepped away from me and jumped when I said "are you done yet?" I looked over at the shorter skeleton and asked "What are your names?"
"I-im sans and my br-boss here is Papyrus."
"Alright, I apologise for my attitude and hope to have a better relationship with both of you." To make my point clear that I wanted to befriend papyrus as well I looked over to him but he was gone. Must have scared him a bit to much. Fuck. I'm not doing so well on making them trust me. Im not a very trustworthy person I suppose.
