Underfell!Sans x Reader (Title to be Decided)

~1~

                  

A grunt of pain rang out from the alley nearest to you. As much as you wanted to get home, you weren't about to walk away from a pained sound like that. Peeking around the corner, you were met with the sight of a tall, thin skeleton monster looming over a shorter, stocky one - who was on the floor.

"BLITHERING IDIOT!! That's got to be the millionth time you've failed me!" the taller one yelled, seemingly furious. His voice was growly, with a smidge of gravel and scratch.

"b-boss, listen i-"

SLAP

The taller skeleton whacked the smaller one in the head. "SHUT YOUR FACE, BROTHER!"

The small one shut up immediately. You were astounded. Why was this guy beating up his own brother?!

"All I asked of you was to stand guard outside my VERY important meeting, and what happens?! You. Fall. A-FUCKING-SLEEP!!"  the tall skeleton screeched, his voice raising as he got even more angry.

"'e-ey, to be fair, boss, i-"

"What did I say about speaking?!"

"..."

"That's what I thought, you fucking degenerate." Tall skeleton spat. "Because of your stupidity, Asgore was almost ASSASSINATED. He was lucky to have a proficient royalguardsman, such as myself, to protect him."

It was at that point you decided to step in, despite whatever threat was posed.

"H-hey!" you called, trying to sound assertive.

The tall skeleton whipped around to face you; the small one struggled to look up, and you could see a massive crack down his skull.

"Didn't your mom ever tell you not to hurt people?" you shouted, trying to sound intimidating.

The tall skeleton raised a bone-brow. "What gives you the right to approach me, puny human?"

"Oh, ya know. Freedom of speech, et cetera. I don't remember a rule saying humans can't talk to monsters." you stated, hoping he didn't see you quaking in your boots. "And anyways, I think your brother has had enough."

Tall skeleton marched up to you, his towering height becoming obvious. He grabbed you by the scruff of your neck and lifted you clean off the ground. "Obviously, you don't know who I am. I am the GREAT and TERRIBLE Papyrus, Head of the Royal Guard, and superior to a tiny, little human like YOU!" he declared. "I have clearance to obliterate interfering mites... which you just happen to be."

He was about to continue his rant when... SMACK! You were on the ground, and so was the "Great and Terrible Papyrus". Smaller skeleton had managed to get up and knock Papyrus out. You quickly sprung up and darted to Smaller skeleton's side. He was clutching his head, and didn't look too pleased.

"th' hell're you lookin' at?" he mumbled.

"Dude, you look like shit..." You said, worriedly.

"and you care, why?"

"uh-"

"yeah, exactly. now go away."

"I can't just let you bleed to death!"

Smaller skeleton looked shocked for a second, but quickly went back to scowling. "wow, didn't realise humans were this stupid..."

You were about to ask what he meant when he suddenly staggered up, still clutching his head with one hand.

Oh.

Jesus Christ.

He may be shorter than Papyrus, but this guy was a fucking tank. He was a head taller than you, and saying he was 'big boned' was probably an understatement. You would've shrank back, if he hadn't fallen down as quickly as he'd stood.

"Uh... are you ok...?" you asked.

"what part'a 'go away' don'tcha get?" Small skeleton snapped. He had a thick New York accent, the type you see in gangster movies.

"The part where you're injured. Badly." you responded. "I can help you, you know."

"what, and put my life in the hands of a human?" he said, sending you a sharp glare. "thanks, but no thanks."

You decided you weren't having any of his crap, and shoved a piece of monster candy in his face.

"Eat it."

He gave you a venomous look, but took the candy anyway, sniffing it. The expression on his face become one of genuine surprise, but then quickly turned to suspicion.

"...y'have monster food...?" he asked, a brow raising,

You nodded.

"who'd'ya kill ta get this...?" he pressed.

"Uh... no one? I bought a pack of them from the store near my apartment." You explained.

Small skeleton glowered at you with narrowed eyes, before cautiously unwrapping the candy and popping it in his mouth. You wondered how he swallowed it - being a skeleton with no oesophagus - but quickly decided that skeleton monsters must work differently from corpses, considering magic was involved. When he stood up this time, he didn't fall. He shoved his hands in his pockets and turned to face you.

"uh... I guess I should say thanks... for helpin', I mean." He said, rather awkwardly.

You grinned at him. "It's no problem... uh..."

"sans."

"Right, sans." You repeated.

"y'might wanna get the hell outta here before boss wakes up." Sans warned.

You were about to ask where he was going, but he vanished into thin air before you could say anything, leaving you standing dumbfounded in the alleyway.

Just who the heck is this 'Sans' guy...?
