Summary
Ink tilted his head, feigning innocence. Error was far worse at keeping secrets than he thought.
“Oh so you two are having a sleepover? C’mon gimme the details, whatever you two get up to is safe with me.”
“nothing happens.” Error sneered. “and nothing’s gonna happen. besides, i’m not gay.”
Or, Error and Ink make a bet

Summary
Error gets stuck when reaching through a hole for chocolate during a supply run and Nightmare appears before he can get himself out.
The hand trailed lower, and the glitch stilled, eyes going wide as phalanges played with his waistband under his coat. His Soul pounded in his chest, and suddenly Error found himself hyperaware of how vulnerable he was. "WhaT—?"
"Come on, think about it, darling. The poor defenseless maiden gets trapped and the big bad wolf comes along to take advantage."
"I-I'M Not A DeFEnSLess 'MaiDEn'!" He immediately sputtered, but that didn't stop his cheeks from turning bright gold as the idea was planted, "An-And DoN'T CaLL Y0uRSelF A WolF! ThAT's FuCKinG GrOss!"
Error squeezed his eyes shut, shaking his skull and trying to get the thought out of his head. Stars, he didn't like the implication there! He didn't want to think about it! And yet he couldn't help imagining what it would be like if the scenario played out— the position he was in, the teasing, the predatory gaze boring into him…
The glitch swallowed nervously, the heat spreading further across his face.

Summary
Error had really thought he was finally settled into his role as the destroyer, even finding little ways to enjoy it. But when he’s interrupted celebrating a job well done by his nemesis and natural opposite, Ink, things take an unexpected, world shattering turn for the worst, and someone he had thought of as perhaps a friend became someone he wished he’d never had the displeasure of meeting.

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!"

Summary
Error accidentally catches Ink cheating on him with Dream and vents to Nightmare, who recommends an unexpected method of revenge.
The glitch stifled a shocked curse, scooting back on the bed as his eye sockets went wide. "Wh— wH4T?" He sputtered, "You— YoU w4NNa kiSS m3 in FroNT of INk or sOMeTHin'?"
Nightmare snorted dismissively, rolling their eye-light as they pressed one of their hands right next to his head. "Darling, you're cute when you're dumb— but no. It's clear that those two morons likely got a little more… intimate than that. It wouldn't be proper revenge if you didn't go just as far, no?"
Error's flush went all the way down to his shoulders at their words, his Soul jumping into his throat. Were they really saying—? They wanted— with him—? "I-IsN'T th4T g0iNG a-A liTTle toO F4R? I-I kn0W you w4nT to Help m3 get Re-ReVEnGe, But—!"

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.

Summary
Ink and Error fight over the fate of a Universe, which ends unexpectedly after Error gets pinned against an alley wall.
He swallowed heavily—Soul pounding in his ribcage—and threw an elbow over his shoulder.
"Just stay still!" The Creator snapped, ducking his head to the side of the hit. He slammed his full weight into Error, firmly shoving his entire frontside up against the filthy wall as the glitch wheezed from the pressure.
Only this had one tiny consequence.
Both Skeletons froze in place, eye sockets going wide as they realized that Ink's hips were pressing right up against Error's sacrum. Error stared at the wall with small eye-lights, struck silent and mind completely blank with shock. What— What the fuck? Ink was… was…!

Summary
Ink ties Error up after he goes on a rampage, but Error didn't expect him to go further than that.
As if he'd jinxed himself, Ink let out a startled, "Woah! Is that...?"
The Creator walked around him to his lower half, Error feeling his face burn with embarrassment. He tried to turn over—to bury his frontside against the gray dirt of Waterfall—but then he felt a foot press onto his thigh. And he was turned right back over, legs pinned into the ground with the bulge in his pants facing straight up.
"M-MhGhFk!"
"Holy shit, you really are hard!" Ink blinked a few times—jaw almost hanging open for a moment—before tilting his head, eye-lights switching shapes rapidly. "Is this— is this turning you on?"
Error's eye sockets blew wide at the question, flush spreading even further up his skull. Stars, he couldn't believe Ink thought he was— he was—! He shook his head quickly, making muffled sounds of protest, and writhed against the pressure on his thigh in an attempt to turn over again. The other Skeleton only pushed harder on his leg, keeping him in place.

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
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 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.

Day 1: Teratophilia/Size Difference by Destiny_Of_A_Dragon

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!
