{requests OPEN!} Undertale Au Characters x reader One-shots

Fell sans x Tech-Wizz!reader

A/N: ok. normal Underfell. lets see how this turns out. and in this, Underfell is the original, not Undertale. and you are a tech wiz, so yea.and i'm using this to...stall you...kinda...so i can get other requests done.

You had achieved every ending; pacifist, genocide and all neutral routes. This time, you were planning to delete some files. Which files?

0 and 9, of course!

As soon as you clicked 'delete' and reopened the game, you received the dirty hacker ending. you went to restart the game when the computer shutdown. you shook your head and did several things to bring it back. nothing

then, the computer restarted itself and the game opened as normal. you were confused, but brushed it off, recovering the 0 and 9 files. you played for a while, but as you made it to Snowdin, the game froze. you knew several tricks behind this, but decided to wait.

turns out the game wasn't frozen, but waiting for a certain character to appear. Sans appeared, and then your sprite disappeared. you went to close the game but-

"i wouldn't do that," you froze. "You're the one behind that route, and i'll give you a choice. play pacifist, and don't touch the game, or i'll drag the real you into this mess," the game closed. this message confused you slightly, but you reset the game. only, the player sprite wasn't there.

"what the..." you said. "this isn't...supposed to happen..."

"Have fun, player," said a voice. then, you fainted.

~time skip~

You woke up in a shed, a shock collar around your neck. you couldn't move, and found you were tied to a chair.

"took you long enough to wake up," said a recognisable voice. "didn't know the player would be so...pretty," you blushed at Sans' compliment.

"lemmie guess, Sans. you're gonna keep me hidden from your brother, and torture me, then drag my dying body to the king when you get board of a pretty playtoy like me," you say. Sans' breathing faltered.

"depends..." he says. "you were in control of Frisk, and so that tells me I should give you a good time,"

"true,"

"but i'm not going to,"

"wha-"

"shut it. i'm gonna go get Boss," he teleports, and you get to work on escaping. you have a screwdriver in your picket, and use that to cut yourself free. you had forgot about the shock collar, and as you went to leave, you got a harsh shock and fell to the floor, unconscious.

~time skip, Sans p.o.v.~

I left the kid to go get boss, who was probably still at Undyne's. either way, he'd be...ok with me finding a human. as I reach the edge of Snowdin, Boss comes to greet me.

"SANS! WHY ARE YOU NOT AT YOUR POST?!" he yelled, and I dodged a slap.

"well...I found a human and trapped them in the shed for ya'" I said, scared of being attacked. Boss ran off. 

~normal p.o.v.~

Sans and Papyrus reached the shed, and opened it to find your limp body on the ground, the collar delivering a small shock every few seconds.

"WHY IS THE HUMAN DEAD?!" Papyrus asked.

"they were shocked into a sleep. we'd have to get them inside," Sans picked you up, and went to leave, only to be met by his brother's harsh glare.

"YOU LIKE THIS HUMAN, DONT YOU SANS?" papyrus asks. Sans blushes and nods, taking you inside and putting you on the couch, covering you with blankets. Papyrus walks into the kitchen to male some spaghetti for you when you wake up.

"you really are a strange kid, Y/N," Sans whispers, stroking your hair. you seem to smile at this in your sleep. "you're really something to make me...like you,"

~later~

Papyrus had decided to let you live, despite you being human. You had woken up, and Sans was treating your injuries. you were both silent.

"HERE IS YOUR SPAGHETTI, HUMAN Y/N!" Papyrus hands you a plate of his spaghetti, which tastes...indescribable.

"thank you, Papyrus," you say quietly. Papyrus leaves the house, leaving you alone with Sans.

"How come you haven't killed me yet?" you ask. Sans stops for a second before answering.

"you're not what I expected," he says.

"there goes 'kill or be killed'..." you mutter. you finish eating and head to your room. maybe you could do something other than live in fear of death. grabbing a coat, you ran straight to Asgore.

"A...human? why are you here?" he asks. you hold back tears.

"i came here to give up my soul. so I can set free the only person who cares," you say. Asgore stays silent. "please...make it quick and painless,"

footsteps. and a scream.

"WAIT!"

~meanwhile~

monsters were making their way to the barrier. to the surface. Sans hadn't seen this, but when he went to go to Grillby's, he was met with papyrus.

"THERE YOU ARE SANS! THE BARRIER IS BROKEN, GET YOUR THINGS!" Papyrus ran inside to grab his things. it took sans a few seconds to realise what papyrus had said. he ran inside.

"Y/N?! Y/N where are you?!" sans did a quick search of the house before it hit him.

The barrier was broken. You were missing.

"no no no !" sans mumbled, teleporting to the castle. no monsters had made it to the castle yet. sans ran into where you would be. he could see your s/c soul glowing. he began to approach it, and soon saw you standing before the opening to the surface. you were alive.

"it...worked?" you whisper. "that was- AHH!" you were practically tackled from behind, but stayed upright. you tried to free yourself, but realised two things.

one, the person who was hugging you was Sans.

two, he was...crying?

"Sans...?" you whisper.

"i cant loose you or paps..." he whimpers. you hug him back, whispering consoling words. slowly, he calms down.

"there...better?" you ask. Sans only nods. "ok. lets make a quick stop home, then we'll go to the surface, and we can see the stars," sans eye's light up like stars at the word. you giggle.

~time skip~

"Y/N the computer broke,"

"did you turn it off and on again?"

"yes,"

"did you close all programs and restart the wifi router?"

"yes,"

"blast the computer,"

"ye- WHAT?!"

"hehe~ i'll fix it," you leave your (fave anime) playing and go to yours and sans' shared room. you go to ask what was wrong with the computer, but were met with a kiss. as he pulls away you are left frozen and blushing.

"can you fix the computer now?" he asks. you sigh, restarting the computer. it works normally.

"the computer was really fine, wasn't it?"

"smartie,"

"you just wanted a kiss, didn't you?"

"no..." he mutters. you kiss his cheek.

"love you too edgy," you say, walking off. you can almost hear him whisper something. something like...

"damit y/n...you sexy player,"
