Rattled (Sans X Reader)

Saved

     My eyes fluttered open. There were a TON of blankets on top of me.
What happened? Had I passed out? I looked around. I was on somebody's couch, in somebody's house. Oh wow. I looked down in I saw I was wearing a blue jacket. I was so confused.
Just then, the lights turned off, and I heard footsteps. I saw a black siloette (HOW DO YOU EVEN SPELL THAT) and it walked towards me. I hid under the covers. I was understandably terrified.
A deep, male voice then said, "Is that any way to greet a new friend? Shake my hand," I uncovered myself and hesitantly shook their hand. Then I heard a farting sound. I started laughing like crazy. Wow.. I am an idiot. The lights turned on.
I was finally able to see him. He was a... skeleton, I guess? That defies so many physics. He had on a white t-shirt, black shorts, and pink slippers. For some reason, I wasn't scared. Probably because of the whoopee cushion prank.
"i'm sans, sans the skeleton," he said.
"I'm Y.N, Y.N the human," I replied. We both cracked up.
"BROTHER!! WHERE ARE YOU???!!!!" I heard a voice screech. (Yep, annoyed)
Sans whispered to me, "That's my younger brother, Papyrus. He's so cool! And loud," (I gave up on the all lowercase thing, too lazy)
"I can tell," I replied. We both silently laughed. Just then, a tall skeleton walked in the room, jaw gaping open. He had on a red scarf, a white chest plate, and what looked like... red underwear...? I'm not gonna question that. Too lazy. He was taller than Sans, which was weird, since he is theoretically younger.
"YOU CAPTURED A HUMAN, SANS!! I AM SO PROUD! I CANNOT WAIT TO TELL UNDYNE!" Papyrus exclaimed, "I SHALL FINALLY BE POPULAR AND HAVE LOTS OF FRIENDS! AND.. Mettaton, maybe..." I couldn't hear the rest. (I don't ship it, but I think it would make this book more interesting. So I shall torture myself) Papyrus began blushing orange as he muttered to himself.
What has happened to my life.
