Sans AU One-Shots

❀Killer❀ || until we drink.

Heavily inspired by the song Until We Drink ^

Pairing: Killer Sans x Female Reader
Prompt: The relationship between you and Killer is nothing more than friendship - until you drink.
Type: smut
Length: 4.4k words
Background: This is similar in a sense to 'bitter.' (the one with Killer and Dust) as far as the whole Nightmare situation since that feels both in character and somewhat canon - assuming I know my canon, at least.
Notes: I'm in a Killer phase rn so bear with me lmao (I was just minding my business and saw a particularly amazing piece of fanart of him and it hit me like a bullet, literally an 'oh no I love him' moment 😭) And yes, that means I wasn't a Killer girly before this - trust I've been converted lmao- | And the song lyrics I use do come from actual songs (part of my playlist as I wrote this)

We clinked our glasses together then threw the shots back, a gasp leaving my throat once the burn hit my throat, and I laughed. "Ack, that shit is strong." Killer rubbed my back as he hovered his shot glass over the kitchen sink, his hold on it anything but tight, and the next second, it slipped from his grasp and shattered in the basin.

"Good going, Kills," Dust grumbled, wiping his mouth with the back of his hand.

"Oh lighten up, Dusty. The Boss ain't around so you can take that stick out of your ass." Killer tried to clap Dust on the back but the normally silent skeleton ducked away from his touch, glaring daggers. His hood wasn't up for once so we could all see his irate expressions, but it wasn't like we weren't used to it. He was an angry drunk just like Killer was a happy drunk – he was normally happy, but the drinking made it astronomically worse. Horror typically opened up more the more alcohol was in his system, but today he was quiet, watching Dust and Killer's spat with a vacant gaze. It wasn't like it was interesting after seeing the same thing play out so many times.

I leaned against the giant as I held my shot glass up to him. "Could you pour for me?" My bright smile brought a chuckle from his teeth, and he reached for the bottle, the label I couldn't read anymore – but it wasn't like the type of poison mattered, especially not when I was plastered like this.

"You're not gonna be able to go home tonight, (Y/n)."

"Darn." I put a lot of effort into sounding disappointed but my laughter shatters the illusion I'm trying to cast. "You got room in your bed for me, then?"

"I'd crush you." The thought brought a worried frown to his mouth, and I reached up to pat his arm reassuringly.

"That's assuming I don't choke on my own vomit before then!" My words did nothing to soothe him, and in the back of my mind, I heard a little voice telling me to stop teasing him, he was an anxious drunk. "Don't worry, Killer takes good care of me, Hor." His teeth started to curve downward at the nickname – one he blatantly didn't like because Killer loved to call him 'whore' and play it off like it was just a shortened version of his name.

Dust scoffed, shoving Killer away and stumbling away from the sink in the process. "Yeah, it's a wonder he doesn't squeeze the life out of you while you're sleeping."

Killer gasped, feigning hurt as he put a hand on his sternum. "I take very good care of the human! Tell 'em, darling." He wrapped an arm around me, partially leaning on me to stay upright, and a laugh bubbled out of my throat.

"He takes such good care of me." I caught the subtle look Killer sent my way and I playfully shoved him, holding a finger to my lips while I shushed him and spilled some alcohol on the floor.

Dust rolled his eyelights, downing another shot before slipping his hands in his pockets. "I'm heading to bed, you guys are insufferable."

"Says the one who talks to himself!" Killer called after him, earning a glare from multicolored eyelights.
