(Au) Undertale One-shots!

Skeleton reader x posseive nightmare [part two]

You fel your eye twitch from utter annoyance at Sans's obsessive puns. 

Don't get me wrong, you liked them...mostly. But you had a limit , and that boy had far surpassed it hours ago. And it was taking every inkling of will power NOT to go down there, and wack him with a pillow.

But you also knew that one of the reasons he's been more, punny than usual is because of his nightmares. He was on the couch one night, silenly sobbing as glowing ecto tears trailed his skull as you tip-toed downstairs. You gotten the munchies and was planning on stealing some of Your older brothers' fries from Grillbys, when you had found, said skeleton on the couch. 

He was always more of a laid back kind of guy, so it surprised you a little seeing him cry openly like this. But, you being the sweet yonuger sister you were, strided up to him, and plopped your boney butt on the couch beeside him.

Sans had questioned you what you were doing up, only for you to sass him [lovingly lmao] and used reverse psycology on him. After prodding for  twenty minutes non-stop he finally confessed his nightmares.

A Human falling down, killing everybody in their sights. But the worst part according to him is they killed papyrus who still believed in them . And as he was about to be killed, you had apparently jumped in front of him, taking the critical hit, and turning to dust before him where as he had only found a dusty orange scar of papyruses.

you both agreed to keep it from the youngest skeleton and moved on.

But lately you've been gettting your own nightmares. Of a inky figure which you could never figure out. And a couple of different sans-es.

Oh yeah you knw of the timelines and stuff. 

at least you remmebered the other au timelines. lol..

Long story short, you were doing something in ya'll shed when a portal of black opened up, and out came a glitchy skeleton looking like your brother. You just stood there blinking in shock. Fortuqntely you had always been calmer to random things like this happening since you found papyrus that one fateful day and basically raised him, til sans popped outta nowhere like yourself and papy and ya'll became a family.

So you only rose your bone-brow as you returned the icy glare the black skeleotn shot you.

"Get out of my w-w-w-ay" he growled to you pissing you off but you kept your calm.

"Excuse you bud, but YOU're the one in MY shed. SO if anything, YOu get out of MY way." You crossed your arms sassily. "You're blocking the vaccum." 

Seriously, Sans made a mess per usual but this time in your room and u werent too pleased with him atm.

Before the glitchy sans-look-a-like could threaten you, another portal opened up , looking like the raimbow barfed in a single spot as another....sans??? popped out with a big ass paintbrush on his back and colorful shaped eyes.

"ERROR"

"f-fufck" the black one said before leaving through the glitch portal.

Before the colorful skeleton could escape you blocke it with a gasterblaster, with e/c light.
