Dental Hygiene

The door the frosting-caked pair had stepped through led to a long, narrow hallway. The floor was silver-gray, but the walls were paneled in alternating panels of bright pink and purple. The ceiling was white with a popcorn texture, set at regular intervals with fluorescent tubes that gave off a cold white light. The hall was so narrow that they had to go single-file. Celestia was therefore treated to a long view of Luna's tail as they walked.

The hall was long enough that they had been walking for what seemed like forever, and Celestia had rather thoroughly tuned out, so that when Luna suddenly halted, Celestia nearly ran into said tail.

"What is it?"

"The floor is about to become a conveyor belt," said Luna, gesturing ahead of her. Celestia peered over her shoulder and saw that the floor ahead of them was indeed divided into conveyor segments that slid steadily forward. "I suppose there is nothing to do but continue onward," added Luna with a sigh. "Ah well. At least it will be a rest from walking. I begin to grow tired." She stepped forward and let the conveyor carry her down the hall.

Once Luna was out of the way, Celestia did the same. The hall remained unchanging, the wall panels sliding slowly by, for some time. Suddenly boot-like objects slid out from beneath the conveyor belt and clamped over each alicorn's hooves, fastening them to the belt's floor panels. They both yelped and tugged at the boots. Celestia stopped after the initial surprise had passed. There was no point in struggling. If she got free, where would she go? The only way to rescue her friends was to go forward. Luna, though, continued to fight, thrashing her sticky wings and lashing her tail.

Panels on the walls some distance ahead of the sisters slid aside, and a set of massive roller brushes slid out of them. With a whir they began turning, and jets sprayed soapy water on the brushes. Luna and Celestia both froze, then, realizing what was about to happen, Celestia burst into laughter. They were going to be cleaned! In a very undignified way, but she didn't care. She wanted the caked on slime and frosting and everything else off.

Luna apparently felt differently, for she kept struggling. Celestia shook her head, bemused at her sister's continued fighting. What purpose did it serve?

"Yeep, cold!"

Celestia couldn't bite back a giggle as Luna reached the first brush and was pummeled with wet, soapy bristles. A moment later, though, it was her turn and she couldn't help but yelp a little bit. Luna was right, the water was freezing cold. She closed her eyes and braced herself as the brush rubbed over her head and down her back.

Others popped out of the walls and cleaned her sides. Smaller brushes joined them, pushing her wings around, getting all the frosting and goo from her feathers, though also leaving them in disarray, pointing every which way.

More brushes scrubbed her mane and tail. Then a giant padded clamp closed over her middle, while the boots on her hooves let go and another set of brushes scrubbed them too.

Her hooves were re-clamped and the conveyor carried her onward, through a rinsing shower of cold water that sprayed her from all sides, leaving her drenched and shivering, but much cleaner than she had been.

Finally a set of gigantic fans blew so hard that it might have knocked her over if she weren't clamped down, blasting water from her, leaving her merely damp rather than soaked.

The boots on her hooves vanished, and the conveyor slid on, finally depositing both alicorns at the end of the hall, in a square room, whose walls were still bright pink and purple but which was otherwise plain and featureless.

"All squeaky clean!" Discord popped into existence next to Luna and ran a finger along the latex clown suit she was still wearing, making it squeak.

Luna shied away from him with an oath, her horn glowing. She released the magic and sighed a moment later. "Discord. I suppose I should thank you for cleaning us, though I did not find the method particularly dignified."

Discord cackled with laughter. "You haven't even begun to experience undignified, Moony! But I didn't clean you for your benefit. I cleaned you so that I wouldn't have to taste all that muck on you."

Celestia's head whipped around and she stared straight at Discord. "Wait a minute. Taste?!"

Discord grinned, and suddenly the room seemed to fall away around them, while Discord grew massive, towering over them. His smile stretched wide and he swooped down, jaws open, and snapped them both up in his mouth.

Celestia and Luna found themselves enveloped in a warm, wet darkness. Both alicorns were braced for the moment when Discord would swallow, but it didn't come. Instead, after a long pause, he opened his mouth. Not all the way, but just enough for the two, now tiny, barely two or three inches high, to struggle to their hooves on the soft, fleshy surface of his tongue. His teeth were just parted around them, creating a jagged prison of ivory bars.

With a soft "paff" sound a pair of toothbrushes appeared in front of the two alicorns. One was blue and silver, the other white and gold. Given the teeth currently surrounding them, it didn't take much mental effort for the alicorn pair to realize what they were supposed to do.

Celestia picked up the gold and white toothbrush. Luna scowled, but picked up the blue and silver one.

"I'll take this side, you take the other side," said Celestia, jerking her head towards the nearest row of molars.

"I suppose if I must," said Luna.

Celestia found a little smile on her face. She wasn't really enjoying this either, but something about Luna's cranky dissatisfaction was just so her that it was amusing.

Unfortunately that was the only amusement to be found here. She held the giant toothbrush awkwardly in her hooves, her magic didn't seem to be working once again, and scrubbed at the massive molars. The yellowed ivory was caked with plaque and little food fragments. Discord hadn't provided toothpaste, so they just had to scrub and scrub and scrub with the brushes. They were too big to hold in their mouths, they had to use both hooves, and balance awkwardly while working away.

On top of that it smelled of halitosis, a disgusting fragrance that neither mare could escape for even a moment, since the whole mouth they stood in reeked of it. And of course they were standing on a wet, squishy, tongue the whole time. It was one more unpleasant, humiliating experience, piled on top of the others they'd already dealt with.

The only good thing about it was that it was relatively straightforward. It took what seemed like an eternity, as they scrubbed their way forward, and wedged themselves between his teeth and cheeks to clean the outsides, but there was nothing more to it. They scrubbed and scrubbed and scrubbed, their latex suits slick with saliva, and eventually they finally reached the single giant fang at the front of his mouth.

When that too was clean they sat back, surrounded by sparkling teeth, completely free of plaque and tartar. They set down the toothbrushes and waited, expecting some kind of door to open up.

"Very good," said Discord, his tongue tossing them around inside his mouth as he spoke, his voice and overwhelming booming all around them. "Now, down you go," he added.

"Down?!" said Luna, but they had no time for any more reaction before the jaws closed down around them, the tongue came up, pressing them against the roof of the mouth, and then it pushed them back until they were at the very back, where the uvula hung down. With one more squeeze, Discord's tongue pushed them further down. Then he swallowed, and they were carried down into the wet darkness below.
