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

//hey that meme is my favorite, check it out 😅//

I opened my eyes, groaning. Ugh why did everything hurt? Why is it so dark? Where am i- I was cut off by my memory's of falling into the pit. "Oh" I thought "better get going"
"I wouldn't do that if I were you." A mysterious voice rang out of the darkness.
"And why's that?"
"Monsters are mean out there, they will kill you"
"I think I can handle it, come out, let me see you"
" . . . . Okay"
He poked his face into a stream of light that came down from the top of the hole. And then looked at me asthough he just watched me kill someone.
"P-please don't hurt me, i-i just wanted-ed t-to help!"
"I wasn't planning on it but if you don't point me i-" I was interupted by a scratchy, deep voice.
"Child, are you talking to that horrible flower?" She came into view and she was terrifying (insert large detailed explanation of how torial looks)
"Yeah" I walked infront of of flowey, into her vision and protecting the scared thing "got a problem with that."
"You aren't a human!"
"Really, I haven't noticed!" At that she mumbled curses before throwing a fireball at me which didn't do anything of course because I'm a demon and we'll live in hell.
"What? How?!" Toriel stumbled back and ran back down the corridor. Well I guess I'm not doing such a great job of making them trust me. I look for flowy but it seems he has ran away.
I start down the corridor that I saw that goat woman go down. I fly over obsticals and finally get to a cute little house with a large tree in the front. This must be her house. It seems like this is the only way to go so I open the door to a dark house. No need to snoop so I go downstairs as this seems the only way I could possibly go. There is the goat woman. At the end of the corridor. She is blocking my path to a door, that must be to the rest of the underground. I've gotta get though there. "Please mam I need to go though."
"No I think I want a little free exp!"
"You know that you can't kill me, please I must get though"
"No, you won't kill the rest of the underground without going though me."
"Oh this is what this is about? I know I'm a little threatening but I'm not going to kill everyone. My plan is to free the monsters."
" . . . . Fine but please don't hurt them," she looked at me with teary eyes "they are rough on the outside but they are good people." I nod and walk to the door that she just moved from. I opened the door and was blasted with cold air.
