Summary
404 and Error are sparring, but it escalates unexpectedly when Error tries to pin 404.
"D0n’T M0VE!? ArE yOU S3rioUS!? LEt G0, ASShoLE!"
"You little shit!" The larger Skeleton growled, gritting his teeth. Error barely had time to scowl in response before 404 was shaking his head and pulling him down harder as if to hold him still. "I said don’t move!"
"H-H3Y! YoU—!"
The Destroyer cut himself off with a sharp inhale, now able to feel very distinctly just how close they were. Error’s skull burned a bright yellow and he couldn’t stop the minute twitches of his body as he fully processed what was going on. He tried to yank away again, bracing himself on his mentor's chest, but 404’s tight grip kept him firmly stuck in place.
Why the fuck wasn’t he just letting him get up!? That seemed like the obvious solution to whatever this situation was!

Summary
When 404's heat is getting unbearable, but he has urgent paperwork to finish, he comes up with an idea for Error to help him— if only he could get him to sit still.
"Calm down, brat," the Overlord grumbled, fingers twitching as he held back the urge to reach out, "You said you wanted a day off, right?"
"YeAh, but—!?" His eyes flicked back and forth again, face gradually glowing brighter— spots of yellow appearing here and there. The contrast almost made it look like stars and, somewhere in the far back of his mind, he idly wondered how much it would take for the color to turn fully gold.
"Then why don't you help me take care of this," 404 spread his knees as if to show off the bulge, "And you can have your day off."
"I…" Error swallowed uneasily, a bead of sweat running down the side of his skull. His face scrunched for a second as he glanced away— but then the Destroyer seemed to gain some sort of resolve and took a shaky inhale. His eye-lights met his own for a split second, before they darted back down towards his lap. "…F-finE, PerV3rt!"

I don't know if it's the best way to get to know a character - after all I barely know anything about 404 lol, but I liked it, quite a lot I might add - it almost makes me wish it was a full story.
edit: Unfortunately I can't find any stories that have 404, Hate, Bill Sans or even King Multiverse, so that's it.
I only found two fanfics with Bill, one of them also having Hate, which is sad and disappointing. Besides that, I really wanted a story with 404 :(
I've only seen glimpses of him in one fanfiction or two, bruh.

Summary
After Error stumbles into a massive fight and gets invited to celebrate winning it with the Gang, he’s surprised to find himself spending the night in Nightmare’s bed.
"HnN…?" The destructive Skeleton shifted, brows furrowing even as he kept nuzzling back into the bedding. Why were there hands under his clothes? He squirmed sleepily, his mind slowly catching up with the events that had happened hours earlier.
The celebration, the drinking, the touching, the undressing—
He was in someone else’s bed.
Nightmare was the one behind him, half asleep and running their hands under Error's clothes, caressing him almost intimately. The realization should’ve made him bolt upright, should’ve made him upset, angry, or disgusted— but it didn’t. It wasn’t bothering him at all. That alone should’ve told him he wasn’t thinking straight and yet…

Summary
After a forced extended break from writing (crazy how like a week is considered an extended break to me rn 💀), I found myself having a hard time getting back into the rhythm of things; I've also come to take more notice into how I struggle to write flash fiction.
So, I decided to take a crack at the solution by writing flash fics to revive my pace! And what better way to show my appreciation to some frequent commentors than to gift them?
Probably will end up being a reoccurrence if I find myself slumping, so lets see how far it goes! :)

Summary
Nightmare feeds on too much Negativity and the only way Error can get them to calm down is by letting them use his body.
Error felt Nightmare’s whole body shift and ripple— and couldn’t resist taking a peek over his shoulder again. The destructive Skeleton froze in a soulbeat, eye-lights shrinking as he saw the corrupted Guardian fumbling with their own pants, mind not stable enough yet to undo them properly.
Eventually, the fabric tore— and Error’s eyes went wide as he saw what was underneath. S-stars, that was—! That was—!
Nightmare was currently over twice his size and full to bursting with excess magic, but Error hadn’t really thought about what effect that might have on their ecto!

Summary
Ink is bored of sex, and invites another person into his and Error's bed to spice things up— but he didn't expect Nightmare to use the opportunity to take Error for themselves.
"Hmm, you really are a fool, aren't you?" They chuckled, tilting their head and regarding him with a heated look. The Spirit leaned down over top of him, whispering into the side of his skull— low enough that Ink would have absolutely no chance of hearing them. "We've always had our eye on you, Destroyer. Inky is merely an excuse to get you underneath us."
The glitch went completely rigid, eye sockets blowing wide again as the words sunk in.
"You are the only reason We are here," Nightmare continued, their breath washing across his neck, "and you are going to put on a lovely little show so that your precious Inky will know exactly how much he screwed up by letting us into your home."
He didn't know what to say— he didn't even know what to think, much less how to react. The Destroyer simply lay frozen on the bed, staring up at the other with disbelief.

‘They say curiosity killed the cat. Some people forget the latter part of the iconic phrase. ‘And satisfaction brought it back.’ Error didn't know if he fully agreed with the saying. But he was putting it to the test today.’
Or
Error questions if tying people up like how he does with his strings is a turn-on and wants to try it for himself. But of course things don't go according to plan

Summary
When Error is the unfortunate one to stumble on the Star Sanses in heat, he finds himself dragged right into the middle of it.
He grunted, turning over onto his front, but didn’t get a chance to do anything else as his friend continued pulling on his Soul.
The Destroyer could only let out a confused shout, scrambling to get up even as he kept being dragged along the ground— repeatedly falling down onto his hands and knees again. What the fuck, what the fuck, what the fu—!?
Error cursed, hands reaching out to slam against Blue’s thighs when he got jerked even closer to the other.
He was barely able to stop his teeth from colliding with Blue’s dick, eye-lights almost crossing to stare at it. The darker Monster fought back a stunned gasp, mouth opening and closing with incredulity as glitches flared around him.

Summary
And it was enjoyable; all of it was planned out meticulously and discussed clearly to avoid any miscommunications. Safe words were chosen and the ability to step out days, hours, minutes before it even happened was always there and present. Precautions in place for if someone got hurt, plans in place for if Error crashed or went into a fit. And even with all of that preparation Error was still blown away (quite literally roughly 40 minutes ago) and left reeling after every twist and turn.
