"Kings Do Not Wear Diapers!"

It was just after midnight. King Sombra was beginning to feel tired and as such he was looking forward to climbing into his massive, king-sized bed and going to sleep. The ex-tyrant let out a tremendous yawn as he walked into his bedchamber, where he was happy to discover that his mistress, Rushing Winds, was already waiting for him.

“Hello, dear. Ready to go to sleep yet?” she glanced at him lovingly with her bright orange eyes.

“Yes, that would be wonderful…” Sombra replied softly, before yawning yet again and revealing his sharp white fangs.

“I can see that!” Rush giggled, “And I don’t blame you! Get into bed now.”

Sombra did, and the two ponies cuddled each other as Rush gently pulled the covers over Sombra, and then reached over to the nightstand and turned off the lamp.

Sombra felt Rush give him a kiss as he began to drift off. It made him feel safe and relaxed.

“Good night, dearest” the unicorn murmured before falling asleep in the mare’s embrace.

For a while, the two of them rested peacefully, until Sombra began having a terrifying nightmare. He saw himself as a young colt, back when he was still an orphan, and he could hear the mocking and jeering of all the other young ponies who would frequently torment him for being “weird.” As if he were still that same young foal, Sombra began to whimper. He felt so sad and so alone, and in his dream his eyes were beginning to fill with tears. He felt like there was no way out of the pain and humiliation.

But then the next thing Sombra knew, he was being shaken awake by Rush.

“Wake up! Wake up, darling! You were only dreaming!”

“Huh?” he said dazedly, before realizing he was still in bed, with Rush beside him. His eyes widened as he noticed the fear and concern in the blue pony’s eyes. “Why are you awakening me?”

“You… you were thrashing about and whimpering. I was worried something was wrong. And also…” she stopped abruptly as if there was something that she had decided not to say.

“And also what?” Sombra questioned, a little annoyed from being woken in the middle of the night. “Yes, I was indeed having a nightmare, but it has passed, so you have no need to worry about me. Just go back to sleep.”

But as Sombra attempted to turn himself over and get comfortable once more, he finally noticed what Rush didn’t want to tell him. The bedsheets surrounding him were freshly soaked, as if some pony had spilled a gallon of water on them. But where did the water even come from?

As the answer finally registered within Sombra’s half-tired brain, he was immediately overcome with sheer mortification and dread.

It wasn’t water.

He, King Sombra, former ruler of the Crystal Empire and one of the most powerful and feared ponies of all time, had wet the bed.

Rush noticed Sombra’s reaction and attempted to calm him down: “Hey, it’s okay, accidents happen sometimes, and it was only a little bit—”

Sombra, however, was not having any of it, and his response was exactly what you’d expect from a prideful pony like him.

“Auggh! How can this be?” he shouted with fury, “Me, King Sombra, urinating in my own bed like a tiny foal! This is hardly befitting of royalty!” He was shaking with rage, but he was clearly trying to cover up his feelings of shame and embarrassment, as evidenced by his flattened ears and quivering lower lip.

Rush put her hoof on Sombra’s shoulder. “Calm down, dear! It’s not the end of the world! We can clean this up and everything will be fine!”

“What do you mean, everything will be fine? How in Equestria can I, Sombra, be a bed wetter?” He hissed out the last two words, as if there was nothing he could possibly think of that could be worse than being a bed wetter.

“I mean you’re getting yourself worked up over nothing. You just had a really bad nightmare and you got scared. Every pony gets scared, sometimes. There’s no shame in admitting it.”

“But— but the sheets! Those were hoof-made in Canterlot, you know!”

Rush placed her hoof over Sombra’s lips.

“Forget about the sheets.”

“But-“

“Say no more. I’ll fetch some new sheets. Go get yourself cleaned up.”

As Rush left the room, carrying the pile of wet bedding with her, Sombra sat on the floor, utterly disgusted at the events that had just occurred. He cursed his incompetent bladder for failing him so egregiously, and he crossed his arms like a defiant toddler as he began steaming with rage and self loathing.

Sombra, you careless whelp! You let yourself slip like a foolish child. You have not wet yourself since you were but a little colt, and here you are waiting for your sheets to be changed! What sort of strange affliction are you suffering from?

Growling and muttering curses under his breath, Sombra furiously trudged into the bathroom where he cleaned himself up. After he finished, he returned to the bedchamber just as Rush arrived carrying fresh, clean bedsheets.

“There, all nice and changed!” Rush said as she finished making up the bed. “Now, why don’t we get some more sleep?”

Sombra was about to give in, as he was eager to go to sleep and forget that everything had ever happened, but he then became aware of another concern, which he brought up to Rush:

“I cannot sleep now! What if it happens again?”

"What do you mean?"

"I mean... what if I... have another accident?"

“Well, I do have a solution in mind… if you’d be, um, comfortable with it.”

“Is it a spell or some form of magical concoction that will cure me of this horrid condition?”

“No, I actually had something more... practical in mind.”

Then, seemingly out of nowhere, Rush opened her hooves to reveal a certain, particular garment.

It was all Sombra could do to keep himself from screaming in horror and revulsion.

“A diaper? Have you gone absolutely mad? Me, wear a diaper?” he said incredulously. He hoped that the entire thing was just another nightmare and that he would wake up in the morning, relieved -- and completely dry.
But deep down, the ex-king knew that simply wouldn't happen.

“It’s not a diaper it’s…” Rush stared thoughtfully at the white garment, “Okay, well maybe it is a diaper but it’s not like anypony will see!”

“So what if no pony sees? I am royalty! A king! And kings do not wear diapers!”

“Hmm, well if they don't then I guess you’ll have to be the first. But it’s your call. And your sheets.”

Sombra opened his mouth in protest and for a split second it seemed like he would explode with fury, but instead he just heaved a heavy sigh. She was right — he couldn’t risk having another accident. And it would only be for one night, until he could find some alternative form of treatment the following day.

But it would definitely be the most embarrassing night of his whole life.

Before slipping the diaper over his hind legs, the dark king narrowed his eyes and growled to his mistress in a low, menacing tone:

“If you dare speak of this incident to anypony, I shall personally have you slowly and painfully executed and mounted upon my wall. Do you understand?”

The little pegasus only smiled at Sombra's threat. “Don’t worry, your secret is safe with me, your majesty!”

Sombra felt his anger die away, but only because he realized just how tired he was.

“I’m going to sleep now.” he said glumly.

“Whatever you say!” Rush replied and then yawned as she hopped into bed.

“Mmmph.” Sombra huffed as he got in bed beside her.

“Aww, don’t be so grumpy about it. I promise things will be better tomorrow!” And with that, Rushing Winds gave Sombra a comforting hug.

“Mmmmm… very well.” Sombra grunted as his eyelids grew heavier. Strangely, he actually felt rather calm and soothed by Rush’s affection, even though he was still aware of his issue and the diaper he was currently wearing. But all of a sudden, Sombra felt that everything would be absolutely fine. Within seconds, he fell into a deep and peaceful sleep.

And he didn’t wet the bed again that night.
