The Skeletons NOT in the Closet

Summary:

A collection of Undertale UTMV one-shots and small drabbles that I don't want to make entire stories for.

Chapter 1: The Honey Pot (Insomnia)

Summary:

Pairing: Dream x Error + (Implied! Error x Nightmare)
Rating: Explicit
Warnings: Explicit Sexual Content

Prompt: No longer able to withstand the threat Error and Nightmare make when working together, Dream decides to try a honeypot tactic to get between the two.

It worked a little too well. On himself, especially.

Chapter Text

"D- D- D- DReEAAh-!~" Error made a sound that was a mix between an early 2000s computer having a thermal meltdown and a cat having it's tail stomped upon as he came on Dream's cock.

For the eighth time in a row.

Holy shit-

"Er- Error...! I'msorryI'msorryI'msorryI'msorry-!" Dream was physically incapable of keeping his mouth shut at this point. It was either he kept babbling, or moaned out how much the Destroyer's tight cunt was driving him insane.

It wasn't even supposed to go this far...!

But now his hips were moving on their own, pounding away and away into the rich, black-blue ecto and throbbing every time Error’s insides clung around him. Molding itself to better fit his shape-! Squeezing him down with tiny little flutters that made his entire pussy clench...!

"FUCK-!~" He cried a little as he came, unbidden. Hissing in pleasure and apology as Error whimpered upon the fiercely hot magic pooling in his already stuffed womb.

It was so much...! He'd lost count of how many times he's released inside of the other.

Without thinking too hard about it, one of Dream's hands found the Destroyer's mandible and pulled him into a heated, sloppy kiss; a purr that he'd never heard himself make before - low, deep, and thick with something he couldn’t name - vibrated down within his core. It began to build up as the other skeleton's tongues lolled out in a lewd display once he pulled away, a cute whine leaving Error’s throat as Dream pulled away to loom over the other monster.

His cock never stopped pounding, only growing harder the more Error flustered and gave himself away to the pleasure. The more his face bloomed with that very charming golden flush and his intent sang.

Suddenly, the spirit realized why Nightmare was so possessive of the Destroyer in particular.

He knew his twin was territorial over the things he saw as his own- including his men. It never passed Dream's notice how furious and combative his counterpart would become whenever Dream tried reaching out to his subordinates. It made sense. Nightmare relied more on his thralls than Dream had his teammates.

But he never quite understood why Nightmare extended that same ferocity to the few times he's approached Error.

The two were allies, but anyone who knew either of them at least in passing, knew that Error took loyalty under no one. The glitch was as fickle as Ink- if perhaps not moreso with how his mood was in tune with a pendulum. It was a mystery to him how Nightmare could tolerate such attitude.

That didn't mean however, that the few times they have cooperated with one another didn't leave the Stars severely crippled. Error was a powerhouse all on his own, but with Nightmare and his gang?

Ink often had to portal them out of there while they still had all of their bones intact.

Which was why, in the wake of a particularly harsh blow, after the bad guys managed a power grab for FellDeep and Frozentale at once, Dream had resolved to find a way to put a rock in between his brother and the Destroyer.

"StARs- s- S! PlEeeaSE...!~ D- dREaM! DoN't sT- sToP!~" Error’s etchings radiated such a vibrant blue, only further accentuating the yellow dusting his entire skull, down to his shoulders where his ecto had burned intensly with Dream's marks.

He stared, transfixed and dazed from how fuzzy Error’s pleasure felt in his soul. The Destroyer was always such a heavy and powerful well of rage and bitterness. Just by him existing, Nightmare must've had several boosts to his strength.

But this...!

Dream made a wounded sound as Error’s cunt convulsed around him in another silent orgasm, massaging his length with such warm, velvety heat. He kisses away the tears that broke through, licking the messy magic streams away before they could coagulate into more silken textures.

To manage such positivity from such a blackened source like Error was intoxicating. Error’s fluttering feelings and sweetened intent was thicker than honey, it was lighter than clouds- was this what Nightmare felt when he fed from his negativity all of the time?

If Dream had known ecstasy like this sooner, he'd be hesitant to let it go, too.

"Error...!~ You feel so good!~ Oh my stars...! You're so good, Error!~ You f- feel amazing...!~" Dream didn't know what exactly he was even saying, but just knew he had to let Error know how good he made him feel, how wonderful he was being like this...!

Both of their thighs were splashed and soaked with a combination of their releases, causing a loud clap, clap, clap to bounce off the walls of the room. It made his head feel even more dizzy and heavy, knowing just how lewd the display must've been...!

Stars! Error was just so sweet and cute and his magic was just so warm and inviting...! He didn't want it to stop! He couldn’t stop himself...!

Dream was only planning on forging a truce of sorts. Maybe figure out how Nightmare earned Error’s favor so well.

Oh, he certainly found out how...!

He wondered how many times Nightmare managed to seduce the Destroyer like this. The thought made something burn inside of him, and he groaned in satisfaction when Error gasped, blurry eyelights flaring as Dream's pace excelled.

"You’re a natural, Error! Hah!~ L- Look at how well you're taking my cock...!~ It feels so hot and-! And ti- tight...!~ Fuck! I'm gonna cum again, Error!~" Dream felt his brain entering the last of it's processing. He was sure he could be forgiven the lack of creative dialogue, Error’s cunt was just so tight and sweet around him...!

Error was just too sweet like this, wrapped around him and letting his soul scream with such a pure need for love and affection and attention. Willing to accept such intimacy with just a few soft praises and reassurances!

It made the spirit go crazy!

The other skeleton said something, but Dream was already too far gone to catch it. He clung closer, wrapping his arms tight around his partner, fingers hooking into the back of his ecto as he jackhammered up into the sloppy, slick heat. Laying his claim to the body beneath him with a drive bordering on animalistic.

He couldn’t control himself! Not with Error's pussy gushing around him like he was the only lover he'd ever have. Not with his powerful, unyielding intent screaming with such vulnerable affection/desire/need!

Dream couldn't help his eyelights snapping into hearts at the sensation, from all of the sweet, fuzzy positivity clouding his head and stuffing it with molten desire. He watched Error sob from whatever look he was giving him, felt his pussy suck down and threaten to break his dick off.

That was it.

"ERROR...!~" Dream had the biggest orgasm of his life. Right inside the Destroyer of Worlds' pussy; filling the other god up with so much magic that he'd be feeling the aftereffects for weeks.

"HaAah...!~" A deep-seated satisfaction curled in his soul as Error moaned in delight, sockets blurring with glitches as he leaned fully into the other in his exhaustion. Legs shaking as his pussy convulsed around him brokenly.

As the pair slumped over and fell into a heap, Dream felt his heart skip a beat as his cock slipped out of Error’s pussy. Gaze unable to tear away from where his spend was now dribbling out, pooling between them as Error gave such a needy shudder.

He felt his mouth go dry, watching the liquid honey slosh out from between the other's fluttering lips in fat, lazy streams, with thighs trembling in phantom sensations of euphoria as the cum only prolonged his heat.

Distantly... Dream realized that maybe... just maybe, Nightmare was right to try to keep Error from him.
