Yayayaay I’m finally done!! Thank you guys for being so supportive, and giving me the motivation to actually finish something!!

So without further ado, my first fanfic on tumblr!

*How the polycule might’ve started* —————————————————————————

Nightmare tossed around in his bed, groaning and growling. He hadn’t been feeling himself that day, so he had stayed in bed.

But he was restless.

Nothing was comfortable, and he could barely even think.

He didn’t know what was wrong with him; this had never happened before.

Not this intensely.. not this bothersome.

Though, he had a pretty good idea of what it was.

He had pushed down his instincts for so long, and now it was coming back to bite him.

The only person he could think of that would be able to help was Dream- the only other person he knew who had such instincts as his own.

His brother.. for just a second, Nightmare considered going to him for help.

But no.

He wouldn’t stoop so low as to go to him.

He was a strong, powerful king of negativity- he was practically a god!

He’d just deal with this on his own.

He laid restless for quite a while, before giving up completely on “toughing it out”.

He couldn’t stay like that any longer.

There was only one person who knew what was wrong, and that was himself, right?

He just had to let his instincts take over.

He laid there for another moment, trying to let himself give up control. It was hard; he liked control.

But he’d rather be a backseat driver than deal with the unbearable discomfort in his bones.

He just needed to give into to his urges- he’d suppressed them for so long, he’d forgotten what they even were.

No sooner than he let his natural instincts back back into his mind, he felt the need to get up and make a nest.

He’d had the urge before, and he had plenty of bedding to use as materials too.

But he’d never actually done it.

It always seemed childish to him, especially when he already had such a big and lavish bed.

But he wasn’t going to question himself, not now.

He was just going to do.

So, he got right up and began the destruction of his bed.

He ripped off every single blanket and pillow, throwing them to the floor in one big pile- afterwards starting off to his closet on a mission to gather more.

He had an abundance of blankets and pillows in there as well, considering how frequently he needed to change his bedding in the summer.

He dragged them all out and almost started construction on top of the bed, before deciding that it was just too tall, and his room was far too open.

So back to the closet he went. It wasn’t a huge walk-in closet by any means, but it was still rather sizable.

The perfect size for a makeshift den.. that perfect place to build his nest.

He constructed the pillows in a large nest shape, before covering them with blankets and bulking it out. He packed them in, rolled them up, tucked them around the pillows.

And then he threw one or two over the nest for good measure- to cover up with.

After he was done, he practically collapsed into the nest of bedding, curling up and getting comfortable.

In the dark of his closet, and the coziness of the nest, he was definitely much more comfortable. He thought maybe he could finally sleep…

But no.

Something was still wrong, and the king was still without rest.

The nest felt empty.. far too empty to sleep in.

He needed something to fill it with.

And so, going with the theme of the day, he didn’t stop to think about it.

He just got up from the nest and left his room, going off to wander the halls of the mansion in search of what he needed.

He stalked the halls for a short while, before halting his tracks as he heard the faint sound of voices.

It came from the kitchen- but he was sure the boys were out right now. Who was here?

Well, there was only one way to find out.

He made his way to the kitchen, silent as a shadow as he peered into the room. It was Cross and Error, who were supposed to be on a grocery run.

Maybe they’d gotten back early? Maybe he’d just been in his room for that long? It didn’t matter all too much, Nightmare decided.

As he gazed in their direction, watching them chat and snack on their chocolate, something clicked in the king’s mind.

This was what he needed, cuddle buddies.

That’s why his nest felt so empty.

And they were only talking, too- he was sure they wouldn’t mind a change in location.

He crept closer, the two smaller skeletons oblivious to his approach as he made his way.

He remained completely unnoticed, until he was right behind Cross, one hand rested on his shoulder.

The poor knight jumped in surprise, causing Error to jump as well.

There was a quiet, tense moment where the two just looked up at Nightmare.

They looked anxious, and Nightmare knew they both thought they were in trouble.

He didn’t like that, despite his usual love of others negative emotions. He didn’t want them to be nervous- he didn’t know why.

After a while of standing there, Cross spoke up in a small voice.

He was so quiet, Nightmare would’ve thought he went back to when the knight first got here.

He was so shy back then..

“B- boss..? Is everything alright..? I- I thought you were sleeping-..” he stuttered, but was quickly silenced as the king grabbed him up by his armpits, and pulled him close to his body.

He had one hand on Cross’ ass, and one on his back as he held him like one would a small child.

The poor knight just stuttered and blushed, unable to process what was happening.

Error also looked surprised, but before he could question Nightmare’s actions he was grabbed up by a tentacle and pulled close as well.

He was place over the goopy king’s shoulder, held gently in place by a tentacle.

And with nothing of importance left in the kitchen, Nightmare started back to his room.

The two tried to talk to him a few times, but they got no response outside of a hum, or “everything’s fine”.

On the way they also bumped into Killer, who Nightmare could recall was left home from the mission (to his disappointment) in case Nightmare needed something.

He stared at the scene before him in confusion, before grinning at the three.

“Well damn, boss, if you were that needy you coulda come to me~!” he teased, laughing at his own crude sense of humor.

Nightmare just stared blankly at him for a few moments, before suddenly shooting a tentacle forward and snatching him up as well.

Killer yelped in surprise, completely caught off guard by Nightmare.

He got a bit huffy about it, but his questions were also left unanswered, with Cross attempting to soothe his concerns with a soft “just calm down.. boss wouldn’t hurt us..” as Killer was begrudgingly dragged behind them.

Once they arrived at Nightmare’s room, they were quite surprised to see his bed as bare as it was.

No pillows, no blankets- just the sheets.

Of course, the king didn’t give them a chance to question it, and just took them straight to his little “den”.

He placed them all into the nest, so gentle with them you’d assume they were made of glass.

He liked the look of them three in there, a mixture of fondness and amusement at the sight of their confused little faces.

Of course, he was rather annoyed that his little collection wasn’t complete.. but he’d just have to wait til Horror and Dust got back.

He closed the door halfway to make it darker, before climbing into the nest as well. He curled his body around the three, pulling them to lay against him.

Cross tried to get up once more, and attempted to question seemingly feral king.

“N- Nightmare..? What.. what are you doing..?” he stuttered, looking quite anxious, “what’s going on..?” He was nervous, and Nightmare couldn’t blame him. He didn’t want to scare any of them.. but his brain was so hazy, he couldn’t find a way to comfort them properly.

So he just pulled Cross back against his chest, and pressed a kiss to his forehead.

In his mind he might’ve whispered that it was okay, but he wasn’t exactly there enough to tell if he was talking or purring.

It didn’t matter, though, because soon enough the closet-den was filled with an aura of calm, and the three started to relax.

It was better not to question the odd things Nightmare did, anyway; they’d already learned that.

It wasn’t like this was anything harmful either.. why not get comfortable? It was so, so comfortable..

In the end, thanks to Nightmare’s comforting aura and embrace, they all fell into a comfortable sleep.

An hour or so later, however, the king awoke.

Alerted by the feeling of familiar magic entering the mansion, he knew that the last two boys must finally be home.

He crept out of the nest, careful not to wake the others as he slunk around the castle in search of Dust and Horror.

It didn’t take long, given how easy it was to sense their magic after a mission.

Heightened soul rate, adrenaline, excitement.. they must’ve had a good time.

He slunk into living room, finding them laughing with each other. These two had always been pretty close..

Nightmare found it quite sweet to watch.

They were talking about the mission, making fun of the Star Sanses- from what Nightmare could gather, the enemy had arrived far too late to stop the mission.

It didn’t matter too much to him at the moment.

“So do you wanna give the report?” He could hear Dust ask, “or should I do it?”

The reply was a soft, “I dunno.. we could probably.. just do it together.”

“But shouldn’t you start dinner?”

Horror just shrugged, chuckling to himself, “it can.. probably wait. If they were so hungry.. everyone would be bothering me by now..!”

Dust just laughed with him, “yeah, you’re probably right.”

Nightmare almost felt bad for cutting their conversation short. Really, they always seemed to enjoy talking to each other.

But he felt like he would explode if he didn’t bring them to his nest.. they’d just have to resume their conversation another time.

He finally made himself known, purposely approaching loud enough for them to hear.

They jumped slightly, having not been aware of him before then.

But they were quite used to Nightmare doing such things by now.

“Oh, boss,” Dust smiled at him, “we were just about to come find you.”

Nightmare didn’t really understand why Dust was smiling. Maybe he was happy they didn’t have to actually look for the king, maybe he was happy Nightmare finally got out of bed?

But he didn’t care, it didn’t matter.

Dust was smiling at him, and he wished to keep it that way.

They both started on their little report, Nightmare drinking in their cheerful voices and soft laughter.

It was the only positivity he would tolerate, from his boys..

However happy they were giving the report, though, he had to cut it short.

He would much rather this not take too long.

He walked closer as they spoke on about their mission, purring at their delicious laughter.

They didn’t seem to notice until he got a bit closer than he usually would’ve, confused by his behavior.

“Uhh.. boss?” Dust questioned, before being cut off by Nightmare scooping him up into his arms.

He gave a startled squeak, but didn’t squirm or complain like Cross or Killer. He just.. didn’t care.

The king grabbed Horror too, holding him gently in his tentacles as he carried them both back to his nest.

Dust tried to question him at least once more, but Nightmare already had such a calming aura in the moment that they didn’t feel the need to question.

Once back at the “den”, Nightmare happily placed the last two nest, purring at how wonderful they all looked together.

The two snickered slightly at the sight of what they were seeing, and Dust immediately got comfortable in the nest, prompting Horror to follow.

“So this is why nobody bothered us when we got back, huh?”

Nightmare thought he might’ve answered, but really his only reply was a soft growl as he clambered into the nest after them.

He curled up in the middle of them all, wanting them all against his body. He held them close with his tentacles, making a small exception for Cross, whom he cradled in his arms.

The first three might’ve stirred a bit, but they were quickly lulled back to sleep by Nightmare’s loud purring.

Dust and Horror were quick to join them.

Nightmare loved this; he couldn’t help but love this.

He’d never had them all so close before, and it was like heaven. It was soft, it was comfortable.. it was home.

He didn’t think he was letting anyone sleep in their own beds for a little while.
