Nightwear Moon has her own idea for how Celestia and Luna should spend her retirement. The idea is diapers.

After her retirement, Luna makes a dream memorial as a way to remind herself of what happened with Nightmare Moon.

One thing leads to another, and she ends up dealing with a Nightwear Moon corrupting her dreams (and Celestia's dreams) into silly crinkly shenanigans.

Still, at least it gives them something to do.

First Night - Diaper Dreams

Retirement was of course, entirely luxurious. And not in a "having 100 servants waiting to cater to my whims" sort of way. It was relaxing. Luna wasn't feeling the pressure of being royal, which was exactly how she liked it… a few years of ruling Equestria with her sister had been quite enough.

Celestia was idly looking over her sun glasses as they relaxed by the pool under the warm sun, but… none the less, she was just a little concerned when Luna mentioned her latest project.

"Luna, are you absolutely sure that this... project of yours won't backfire like the Tantabus did?" Celestia asked as she idly sipped on a lemonade, complete with the little umbrella and ice cubes. Celestia was still rather proud that she made the drink herself: after years of being royalty, doing anything herself felt like an accomplishment.

Luna huffed a bit at the question in annoyance. "Yes sister, as I told you a dozen times today, I made it very differently from the original. It's perfectly safe, I promise."

Celestia nodded, taking a long sip of lemonade.

"Still... until the mane six saved you, it was going to head into the real world... perhaps the night we could look at it together, just in case?" Celestia asked.

Luna sighed in exasperation. "It's going to be fine. Nothing is going to go wrong." She insisted.

"The alternative is I nag you about it every day for weeks," Celestia smirked, swishing around the ice cubes in her glass.

"...You know what, I'm sure we can look at it tonight after all," Luna said, conceding defeat. It wasn't like it would take long anyway... right?

After nightfall, when Celestia drifted off to sleep, she found herself with Luna in a swirling realm of mists.

“Well,” Celestia said, amused. “This seems like a good memorial.”

“That isn’t how it works,” Luna replied, with a tch. “It’s not meant to be some kind of big space where the statue is, the idea is that, when I dream, it’s there as a reminder. For the first dream of the night, anyway.”

She looked slightly evasive. “I think. I’m almost sure I got that right. But this isn’t actually a dream yet, so it’s not appeared yet. That’s how that works.”

“You think?” Celestia teased.

Luna nodded. “I think,” she agreed.

“Well, I can hardly argue with that,” Celestia replied. “So… this is certainly your department, not mine. How do we end up in a dream?”

“I can simply make one happen,” Luna answered. “But, since I don’t want to force it, I’ll just use a spell to prompt the dream that would normally happen…”

Her horn lit up…

...and the two retired royals were in a large, sumptuously appointed pleasure room, with tables and chairs made of slender metal and varnished wood, and with windows all along both walls that showed an amazing view of mountains below.

“Oh, very nice,” Celestia approved, picking up a wine glass in her magic and giving it a sniff. “Is this one of yours?”

“Nay,” Luna replied. “It’s simply the dream that one of us would have had naturally. I’m not sure if it’s yourself or me, though.”

The room rocked very slightly from side to side, and she stifled a smile. “Though this is a very nice zeppelin dream.”

Picking up her glass from the pair on the table, Luna had a drink of her own. “That is good,” she added. “Though I wonder if we should stick to rosewater after the first glass.”

“After the first glass?” Celestia replied. “I’d have thought we’d be on the lookout for your statue.”

“We should, but… dreams aren’t like normal places,” Luna pointed out. “If the point of the dream is that we’re travelling a very long way, it will seem like a very long way, but the time between the points of interest will be… diluted. So perhaps it will be that the statue is at the far end of the journey… I certainly can’t see it in this room.”

Celestia looked around, and conceded the point.

“That’s true,” she said. “As I’ve said, you’re the expert, Luna.”

A minute or so later, a pony with a dark coat came trotting up to them.

“Your orders, madames?” she asked.

“Rosewater, please,” Luna said.

“I think I’ll have lemonade,” Celestia selected.

“Of course,” the pony replied. “I’ll bring your refills shortly.”

As she trotted away, Celestia chuckled.

“The funny thing is, I don’t mind that on this kind of place,” she admitted. “Because everyone would be getting the waiter treatment. Even though we’re the only ponies there. Isn’t that odd?”

"I suppose when everyone is rich and important, nobody is," Luna said, the next few seconds and minutes drifting by as what in hazy dream logic was hours.

Luna blinked, realizing based on the pang in her bladder they'd probably drank way too many rose waters and lemonades in the hours that wooshed by.

"Erm, do you think there's a bathroom on this zeppelin?" Celestia asked as she felt a similar pressure in her bladder.

"Surely there is somewhere in this dream..." Luna muttered as she led them through the door the waiter had come through.

Unfortunately, dream logic was striking again: despite being well lit, the princesses were confounded by hallways and pathways that made no sense and all of the signs being blurry.

And there wasn't even anyone around to ask for help either…

"Are all dreams like this?" Celestia asked in confusion as they made it back to their cabin by mistake for the third time.

"Dreams can be... wishy washy on certain details. Like layouts that make any sense..." Luna sighed.

A moment later, there was a musical chime that echoed through the air.

“Attention please,” a voice announced. “Owing to difficulties, can all passengers report to the main lounge?”

“I wonder what that’s about?” Luna asked.

“You can’t tell me?” Celestia asked. “Should I point out that you’re the expert – again?”

“I’m sure you are the expert on ponies, but you can’t tell me every detail of what they’re all thinking,” Luna replied. “But if it’s in the dream it’s probably important, so we should go and see, I think.”

Celestia nodded. “You’re the expert,” she said. “So… lead on.”

“You’re assuming I know which way the lounge is,” Luna replied, wincing slightly.

Fortunately, their standard method of wandering around randomly worked within just a few minutes, and Celestia and Luna found their way back to the lounge.

The waitress from before was standing there with a pleasant customer-service smile, and had a rolling cupboard next to her.

“Good afternoon,” she said. “There are problems with the plumbing, and so we’ve made sure to provide a solution.”

“Yes, there are problems with the plumbing,” Celestia said. “It’s not there.”

“Exactly,” the waitress said, so matter-of-factly that Luna felt confused for a moment. “However, the comfort and convenience of our passengers is important, and we’ve provided a substitution.”

She opened the cupboard, and revealed a stack of… underwear?

“What are those?” Luna asked, lifting one out and inspecting it.

“They’re pull-ups, I think,” Celestia replied. “The kind of underwear a filly would wear.”

“Is this some kind of joke?” Luna asked.

Celestia sniggered.

“What?” Luna demanded.

“You’re the one telling off the dream manifestation!” Celestia replied. “What makes you think you’re going to get anything useful out of… her? It?”

Luna blushed.

“Well-” she began, then stopped. “I suppose-”

She stopped again. “This is a very strange dream, and I suppose it must be your idea, sister.”

“Why do you think that?” Celestia replied.

“You knew what these were,” Luna pointed out.

"Oh please, I knew what these were because I raised twilight and have been in daycares," Celestia said, rolling her eyes.

The waitress seemed completely unfazed by their bickering. "Please put these on or step out of the line. If you take up extra time in line I'll just keep making them thicker."

Celestia scoffed, then tilted her head. "Do we... actually have to worry about wet sheets if we do this? Or don't do this?"

Luna gulped, knowing this area of dream logic sometimes lead to... incidents.

"Erm, dreams can be strange about that... we could end up with wet bedsheets either way," Luna admitted. "But usually following warped dream logic is the safer bet."

"Your sheets won't be wet if you put these on so the line can keep moving," the waitress scolded.

"Nobody else is in line!" Luna protested, seeing the pull-ups were considerably thicker.

"It's just policy, ma'am," the waitress said, and Luna sighed.

"Let's just go along with it for now and see where it leads us," Luna said, putting on a blue pull-up with her cutie mark on the rear, while Celestia put on a white one with her cutie mark on it.

"We should have just put them on when we got in line..." Celestia blushed, the bulky pull-ups now forcing a bit of a waddle instead of being like thick underwear.

“Well, I’m… not sure how the dream is supposed to go at this point,” Luna admitted, with a frown. “Perhaps… we should check to see if we’re about to reach our destination?”

“Oh, yes, for that statue,” Celestia replied. “The whole reason we’re supposed to be here. I’d forgotten.”

She made a face. “I… hope we aren’t going to need to actually use these.”

“You can always replace them with new ones,” the attendant said.

Luna grumbled something, and waddled over to the window.

“Still no sign of anything,” she said, then frowned. “Except for a storm that we seem to be flying towards.”

“Is that a problem?” Celestia asked her. “Does that symbolize something?”

“Storms can be symbolic in dreams, but they don’t have to be,” Luna told her. “I will keep an eye on it.”

Time seemed to flow by, in that odd way it did in dreams, and possibly only moments later there was rain drumming against the windows as the zeppelin rocked back and forth in the wind. The sway made it harder still for both alicorns to move around, and the sound of the rain against the window created a continuous liquid sound.

Luna pushed her legs together, trying not to think about water and drinks, then staggered as the whole zeppelin swayed to the side.

She felt a sudden warmth – then, a moment later, they were back in the mists instead.

“...that was very embarrassing,” Celestia decided, eventually. “Why are we still wearing these?”

“I’m… not sure,” Luna admitted. “Maybe it was something to do with how we put them on in the dream… at least the need to, ah, use the bathroom has gone away.”

Luna didn’t say anything about whether she’d actually used the pull-up. She wasn’t sure herself, so she didn’t have to say anything about it, and it felt dry now.

“...we should probably try again,” she added.

“Really?” Celestia asked.

“What else are we going to do?” Luna replied. “That was one unfinished dream – I must have cast a spell to leave it, without realizing. So the statue should still show up in the next one, since we never ran into it in the first place. And it’s not morning yet.”

"So do we just cast another spell? Or just... wait?" Celestia asked.

"Well... the spell made things odd last time, so let's wander and wait a bit and see what we find," Luna said, leading the pair to crinkle around the fog in search for anything interesting.

Celestia frowned a bit... couldn't they take the pull-ups off?

Suddenly the fog parted, derailing that train of thought as they saw a big movie theatre looming in the fog, advertising on a big neon side a showing for...

"The Multiverse of Nightwear?" Luna said in confusion.

"I think you made the statue wrong, " Celestia giggled as they entered, snagging popcorn and drinks for both of them.

"I didn't put as much in the way of finishing touches on this one, perhaps I missed something?" Luna said with a slight blush as they took their seats. The ads began to roll, starting with a swirl of soda that swirled and sloshed around and around and around...

"Remember: the biggest fans have bigger butts, because they're padded to watch the movie without breaks. Get yours today!" the first ad said, all about different pull-ups. As was the next one. And the next one.

Luna and Celestia started to nod along... it made sense for movies, right?

And then the movie proper began to play, somehow fuzzy and out of focus as they only seemed to be able to focus on bits at a time...

Nightwear's Soothing Diapers

These thick, puffy diapers have Nightwear Moon's symbol on them. They automatically soak up and power up based on any feelings of affection or other positive thoughts towards them or towards Nightwear, producing a subtle but powerful mental influence which gets stronger with even a stray thought. They are especially amplified by actions of submission or surrender towards the diapers themselves, such as wetting – they clean themselves quickly, but the impact on the wearer is much more lasting than that.

As they grow more powerful, becoming stronger and thicker, the diapers may also start suiting up their victims. If the suit is of a particular character, their power-up and mental influence also includes taking on personality traits of that character. …

Then that section abruptly shifted, and shorter parts came up instead.

"Nightwear has many forms and iterations. Sometimes she just wraps you in a cuddly subby hug."

"Nightwear is usually the best friend of cute princesses..."

And so on…

The movie blurred in and out of focus, talking about Nightwear… about how corrupting she could be… how insidious… and both Celestia and Luna nodded slightly as they stared into the swirling effect that seemed to be ever-present on top of the screen.

There were… flashes of unimportant information and images that were just there to explain more about Nightwear, which flashed on the screen in between more of those swirly art patterns.

Neither of the princesses was sure of most of the details of what they were seeing, but then again, it was a documentary. They didn’t have to understand all of it, so long as they learned some of the things it was trying to tell them.

They didn’t have to know what it meant when the black alicorn shook her rump at them for several minutes a moment, so long as they absorbed what the documentary was trying to say when it explained that Nightwear was someone who knew a lot about Nights and Wearing things and so you should always consider carefully what she said.

It went on, and on, and Luna and Celestia lost track of time…

...then Celestia blinked, squirming slightly in her seat, and felt oddly wet and squishy.

For a moment, she thought the screen was pulsing with the words RELAX and WET and OBEY, but when she looked up they weren’t there and she decided she must have been imagining it.

At least she’d been wearing pull-ups, so it hadn’t really been an accident… and now the screen was just showing a black shape, with a coat patterned with stars, and wearing regalia that all-told made it obvious that this was where Luna’s memorial had been in the dream.

“You did a good job, Luna,” she said, and Luna jolted slightly.

There was a faint squish sound as she did, and Luna blushed before looking up at the screen.

“Oh!” she said. “Yes, that is… I did. Good!”

"That's right! You both did good!" the statue praised, the two princesses feeling strange and fuzzy for a few moments as they began to stir, the dream fading away as they woke up again...

Luna yawned as she woke up from her deep, restful sleep. She signed a bit at the warm, soggy squish between her legs… she really flooded that pull-up last night, and these were the thicker ones too. Well, handling dream magic sometimes had side effects. As did handling the strain of raising the sun... no doubt her sister's pull-up was as yellow as the sun like it was every morning.

With another yawn, she waddle-squished her way out of bed and to check on her sister, who was also waking up.

"Morning, Sis," Luna said, as she got a sippy cup of coffee – a convenient way to avoid spills. "We found the statue at least, but then we woke up. We're going to have to investigate again tomorrow."

"Oh that's alright, at least it didn't seem dangerous. But we should certainly make doubly extra sure it's not having any unknown effects on us," Celestia said, her pull-up sagging from her flank. "Now let's get changes done, we're both soaked, as normal."

"At least we can use the training potty when we're awake.. a shame being a royal means everyone else is better at potty training," Luna said with a sheepish blush as the duo waddled to the changing area to get into dry padding to enjoy the rest of the day in.

After all, they'd have lots to explore at night.

Author's Note

Nothing to see here, everything’s perfectly normal I’m sure...

Second Night - Dragon Dreams

The day passed in the usual way, with the two Princesses-Emeritus spending their time relaxing and enjoying their freedom to not be fully occupied with affairs of state.

Celestia had a book she was making her way steadily through. Luna was working on her paints. It was a cozy, relaxed day, and as the sun slipped down through the sky Luna was able to put a cloud on her training chart – not a sun, but not a raincloud.

“Not bad,” she said, out loud, then Celestia joined her. “And I know what you’re putting up as well, Sister.”

She sniggered. “Don’t you think that, as Princess of the Sun, you should be able to put a sun on the chart?”

Celestia stuck her tongue out, putting a cloud on her chart as well.

“Well,” she added, stifling a yawn. “How do you want to handle our night-time excursion?”

“I was thinking that perhaps I’ve been forcing it too much,” Luna said. “Trying too hard to make the dream happen. I’ll make sure to bring you along, but apart from that I’ll just… let the magic take us into whatever my dream would have been anyway. How does that sound?”

“You’re the expert, Luna,” Celestia repeated. “Now, let’s have some hot cocoa before bed?”

Luna’s fresh pullup crinkled a little as it held her hind legs apart slightly, and she yawned before focusing her magic. A weave of spellwork reached out to link her with her sister, and the two of them dropped slowly into dreams…

The foggy haze slowly came into focus, with Luna and Celestia finding themselves in... a classroom?

A university classroom in fact. It had been ages since either of them had been in such a place. In fact, they'd done a lot of teaching at them...

In front of them, wearing a professor's cap and with a Diploma above her head, hanging on the wall that said "PHD in Advanced Absorbency" was... Nightwear?

"Good, you two are just in time for your lessons in advanced absorbency!" Nightwear said, a projector flickering to life that drew in the eye with swirly shapes.

"Um... why are we in this class?" Luna asked, as her eyes were drawn in to the presentation, the first slide being on the optimal thickness of diapers.

"It's your dreams! I'm sure you can explain it better after you graduate class!" Nightwear said. "Now pay attention! We have a long lecture, and there will be a test at the end!"

"Not a test..." Celestia groaned, not feeling at all prepared, but she did her best to pay attention.

As much as they tried to watch the slides, going deeper and deeper into their thoughts into the material, it almost felt like their heads were being filled with big, poofy thoughts. Thoughts about diapers, and how comfy they were, and how thick they felt... but after the attempt to understand Nightwear explaining the volumetric absorbency of diapers, Luna felt even more fuzzy and confused than when they started, and they still had to pass a test.

And then, way too quickly, the presentation ended, making the two princesses blink.

"Alright, here are your tests!" Nightwear said, setting out two sheets of paper, pencils, and large bottles of milk. "You have two hours to complete the test. Begin!" Nightwear said, shaking her spirally pampered rear at the princesses to draw their attention… and use up most of their time.

Celestia found it hard to focus on anything else besides Nightwear's padding, idly suckling on a bottle as she tried to make sense of all the questions...

The only one that seemed to make sense was the second, optional section that said, "Instead of Section one, you can do a practical demonstration of absorbency..." but what did that mean?

Luna was confronting more or less the same problem, but as time came closer and closer to running out she began to blush and squirm for a different reason.

All that milk, and all that time – time that had flown past, not that she’d noticed – had made a certain problem more and more acute. She really needed… something, she couldn’t think of the word, and whenever she got close she found it harder and harder to concentrate.

“How are you doing?” Nightwear asked, and Luna blinked before looking down at her test paper – which was terribly blank.

“Oh dear,” Nightwear added. “Well, you still have a chance to complete the test on time.”

“How?” Luna fretted. “I don’t even know what a practical demonstration of absorbency would be!”

Nightwear chuckled, with a smirk warm smile. “I’m sure you know how to do one, though,” she said. “The information’s up there in your mind… you just need to relax a little, so there’s not so many thoughts filling your mind up and making it harder to focus on what you need to remember.”

“How can we do that?” Celestia asked.

“Listening in, are you?” Nightwear said, and Celestia blushed. “But, if I’m helping one of you out then I may as well help you both out… and what really matters here is that you learn something. So just look at something relaxing, to help you focus…”

Luna blushed, because the only thing she could see that would help her focus was Nightwear’s swirly diaper, but because she couldn’t think of anything else she just watched it go back and forth… back and forth…

“...and relax,” Nightwear said, her voice seeming to echo. “And let those thoughts go…”

Luna relaxed, then realized what a practical demonstration of absorbency would be as her anxiety and confusion drained away.

And blushed, as she realized she’d done one, but that it was also really embarrassing…

"Oh... I uh... think we can give that presentation now..." Celestia blushed, feeling the soggy, saggy, droopy warmth between her thighs from her soggy pull-up.

"See? Wasn't it much easier to relax and let all those thought go?" Nightwear beamed. "Now you can give those presentations!"

"Erm, how do we do that?" Luna asked, feeling a bit fuzzy and dizzy.

"How have I been giving a presentation this whole time?" Nightwear asked, which just made Luna and Celestia blush even more.

"O-oh..." Luna stammered, but seeing time was almost up, the princesses turned around and began to shake their rumps at Nightwear, showing off the faded patterns and saggy padding to their "teacher".

The time ticked down, two minutes, one minute, 30 seconds...

"Time's up!" Nightwear said, and the princesses gave little "Eeeps!" of surprise as their rumps were stamped. "That's an A+! You two can graduate to smarty pamps!" She giggled. "Lay down on my desk so you can get your Diaplomas!"

That didn't quite seem right to either princess, but they also needed changed, and after a lot of blushing and plenty of powder, the two were wearing their nice, thick Diaplomas with all sorts of tiny words on them that would fade when wet.

“There you go,” Nightwear said, with a smug happy smile. “Now you’re all set.”

“All set for… what?” Celestia asked, curiously. “I know this is a class, but a class in what?”

Nightwear winked. “For your dreams, of course,” she replied. “You need to know about this sort of thing to have a good dream, don’t you?”

“I…” Luna began. “I don’t think so?”

“But of course you do!” Nightwear replied. “How else can you absorb the experience of a dream if you don’t know about absorbency! Plus, you’re going to night school, because it’s in your dreams, and also about your dreams, so if you add that all up together you can see how this is a class that will help you learn more about how to do things in your dreams and also out of them. I’m afraid I can’t explain any further though, you’ll have to see what there is to experience in your dreams and see how the experience affects what you think.”

Luna was feeling confused and turned around and upside-down by that point, and Celestia didn’t feel much better.

“It’s okay, it’ll all make less sense later,” Nightwear added. “Why don’t you just sink down deep into sleep and have a dream?”

“But… we are…?” Luna began, then yawned.

She made a mrfle noise, and felt sleepy…

“...says we don’t have much further to go,” Celestia said, checking the chart. “And… look, yep, that’s the big swirly rock! That’s on the map, so it’s all smooth sailing from here!”

She turned, the plastic cover of her diaper squeaking faintly, then spread her wings a little as the ship rocked underneath her. “Turn to starboard!”

“There’s only two of us on the ship, sister,” Luna pointed out, adjusting her hat. “I know we both have captain’s hats, but that’s supposed to mean that neither of us can order the other around.”

“Right, right,” Celestia decided, then shook her head. “All right, then. Let’s turn to starboard! You do the wheel and I’ll set the sails! But we’d better be quick – we want to find that booty!

Luna turned the wheel as Celestia set the sails, sending them on a course to go around the swirly rock.

And around.

And around.

And around again.

"How many times do we have to go around, sister?" Luna sighed, looking at the map printed on the back of Celestia's diaper that looked like it was made with finger paint and markers a genuine pirate map! Every time she looked at the map though she felt a bit dizzy and sorta just did what seemed like the right thing.

"Ummm... I'm not sure! Maybe we need to watch the swirly rock for some clues?" Celestia asked as they turned to face the shimmery, sparkly, shiny rock as they went around and around and around and around, the sloshy sound of water and waves filling their ears.

Luna blinked after a bit, realizing something felt... off.

"Huh... we stopped going around," the dizzy, slightly ditzy pony noticed as they began to sail along the next course the map laid out.

"See? I knew we'd end up going the right way!" Celstia said, sounding a bit too confident. Or perhaps she was just more dizzy and ditzy. Luna couldn't quite tell.

Time flew by, or perhaps that was just how it seemed, as the two adventuring princesses sailed along towards the next landmark… though Luna couldn’t quite make out what it was.

“Stop squirming, sister!” she implored. “I can’t read it very well… ah… aha! I think it’s just over there. It’s called… Dragon Island.”

“Dragon Island?” Celestia repeated. “Is it shaped like a dragon, or is there another reason for that name?”

“It’s not shaped like a dragon,” Luna answered, picking up a telescope in her magic and looking closely at Dragon Island. There’s… let’s see… well, I can’t see a dragon over there, so hopefully there isn’t a dragon.”

“Why not?” a female voice asked.

Luna shrugged her wings.

“Well, because it would be very inconvenient to encounter a dragon…”

Luna slowed down, then stopped.

“Celestia?” she began. “Did you say that?”

“I didn’t say it,” Celestia answered.

They both looked around, at the dragon who’d landed on the deck behind Luna.

She was a big black dragon, much bigger than the two of them put together, and her wings were still half-spread to show a fascinating multicoloured ripple pattern on them that seemed to flow and change with every moment. It was very distracting, but not distracting enough to stop the two of them noticing that the dragon was also wearing a large, thick, poofy diaper.

“Ah,” Luna said, blushing slightly.

"So that's why it's called dragon island..," Celestia said, dazzled by the swirls that made her feel even more dazed and ditzy.

"Are you two pirates searching for the booty?" The dragoness asked with a knowing smile. "Pirates looking for the booty have to pass a little test to get onto Dragon Island to hunt for the booty."

She giggled.

"Y-yeah! We're the best pirates ever!" Luna said, suddenly feeling rather silly instead of ditzy and dizzy. "Show us the test, oh crinkly guardian!" Luna giggled, almost prancing around like a filly with all the silly energy she had!

"Then your challenge is to make your diapers as soggy as mine!" The dragoness declared.

The two sisters looked at each other, confused.

"But... you're perfectly dry?" Celestia asked, feeling dizzy and ditzy, but not that dizzy and ditzy.

"Watch and learn!" The dragoness smirked, leaning over the side of the ship with her padded bottom and dunking her diaper into the sea, making the ship leaaaaaan as the diaper got heavier and heavier before it was swollen to the max, the dragoness heaving her now extra swollen padding onto the ship with a plop.

"Oh... that's very soggy…" Celestia said, now feeling a lot less certain about beating this challenge…

“Well?” the dragoness asked, smugly. “Can you make diapers as soggy as mine?”

“I – I don’t think that’s possible, is it?” Luna said, glancing at Celestia. “Those diapers are so… so… big.”

“And soggy,” the dragoness prompted.

“And soggy,” Luna repeated. “But… how could we even possibly make our diapers that soggy?”

For some reason, the idea of just copying their challenger and soaking up seawater into her diapers just… didn’t occur to her. She may have had a plastic cover on, but that wouldn’t prevent it happening… but it was just an idea that didn’t pop into her head.

Instead her thoughts were spiralling around and around about how soggy the diaper was, and how she couldn’t possibly match it, and how pretty the dragon’s wings were as she spread them and flapped them to make them shimmer with all kinds of patterns…

“Luna, we need to… to… start making our pamps soggy,” Celestia said, a bit vaguely. “By, umm…”

“Well?” the dragoness asked. “You don’t seem to be even starting my challenge! If you don’t, then you must know that I can’t let you on Dragon Island… it’s me who has a say about who gets on Dragon Island. And I say that I can’t let ponies like you on unless you beat my challenge. But you’re not beating my challenge, are you?”

“No,” Celestia said, then tried her best to relax and make her diapers soggy.

She wet her diaper, a bit, but not nearly enough to compete with the dragoness. Not even when Luna did the same. They couldn’t hope to come close, not with the small amount of sog they’d managed so far.

"Looks like I can't let you two ponies on dragon island! Those diapers aren't nearly soggy enough," the dragon tutted.

"Can we pleeeeease come onto the island?" Luna whined. "That's where all the treasure is supposed to be!"

"Well... I can't let two ponies onto the island... but I could bring two dragons onto the island." The dragoness said with a grin, her wings shimmering and swirling some more as she pulled out a Night-Fury and Light-Fury plush suit. "I can train you two how to soak like a real dragon, then you can try the puzzle again~"

"That's... a good idea!" Celestia nodded as she started to wiggle into the Light Fury plush suit. "We can be on the island, learn where all the treasure is, and then come back here and pass the test!"

"Oh dear me! That would be a deviously clever plan! You two are already thinking like smarty pamps dragons!" The dragon giggled, helping Luna and Celestia into those thick, plushy dragon suits... and then layered a new, extra thick dragon diaper onto their already thick padding, just for some extra poofy waddling~

“Now, come along!” the dragoness added, spreading her wings, and the glowing pretty shimmery patterns drew the attention of both dragon-suited princesses.

They followed along obediently, like the kind of sheep that dragons tend to steal, watching as the swirly shiny wings beat up and down and up and down as they flew along with the dragon-suit’s wings beating up and down with their own wings beating up and down as the diaper in front of them swayed up and down… up and down… and down…

“… watch closely,” the dragoness said, spreading her wings. “And listen closely too, okay?”

Luna mumbled something, nodding as she watched the wings flap in front of her.

They were on the island, now, but she couldn’t remember quite how they’d got there… and as the pretty patterns swirled and danced in front of her, she didn’t much care about wondering how that worked.

“This is dragon island,” she said. “So you’re dragons. Just look at one another and you can see you’re dragons. Look at yourselves, and you can see that you’re dragons. I’m telling you you’re dragons, so you’re dragons. It’s obvious that the two of you are a pair of sister dragons.”

“Dragons, yeah,” Luna agreed, nodding her head again.

“A Night Fury and a Light Fury,” the dragoness said. “And those are dragons who know to listen to a big bossy dragon like me. You’re fascinated by my swirly wings. You need to obey and do what I say.”

“Obey…” Celestia mumbled.

“That’s good,” the dragoness told them. “Now, listen closely as I tell you the other things a dragon needs to know…”

Celestia and Luna scooted closer as the dragoness indicated.

Then she gestured for them to come closer, so they did.

Then closer.

And closer.

And clooooooser...

And they were so distracted by the swirly wings and diaper, they were completely unprepared to be sat on!

"All new dragons start as hatchlings! And you two are new dragons, so you must be hatchings!" The dragoness said, her squishy diaper soothingly warm to wiggle under.

"B-but we're big!" Luna protested.

"Yeah! We're not hatchlings!" Celestia whined.

"How long have you been dragons?" the dragoness asked pointedly.

"Um... a few minutes?" Luna said, drawn in again to another dazzling, swirly display.

"Then you must be hatchlings!" The dragoness said, neither princess hatchling able to refute that logic as they were squished, smooshed, nuzzled and coddled under the colourful, swirly hypno pamps...

“..uh?” Luna asked, eventually, squirming a bit and looking around.

She and Celestia were in a big plushy round pillow with a depression in the middle, and the princess hatchling shook her wings out before looking around.

“Um,” she added. “Celestia? Where are we?”

“I… don’t know?” Celestia replied, looking around. “This looks almost like…”

“What?” Luna asked her sister.

“Like a nest,” Celestia said.

“Of course it’s a nest!” a big pink dragoness said. “This is the nesting grounds.”

Celestia jumped, wings flapping a bit, then furled them and looked offended.

“Don’t sneak up on me like that!” she protested, blushing.

The pink dragoness tutted. “I didn’t sneak up,” she replied. “You just weren’t paying attention, silly hatchlings.”

She touched a necklace at her throat, which had a heart on it, and it looked pretty enough to distract both Celestia and Luna a bit as it sparkled.

“...uh,” Luna said, blinking and shaking her head a few times. “Then, um, how did we get here, and where’s the treasure?”

“Oh, you got here because you’re hatchlings, of course,” the pink dragoness said, matter-of-factly. “How else do you expect?”

Celestia blinked. “But… we weren’t here before?”

“And you’re here now,” the pink dragoness replied, then turned around and waved her tail instead – which also had a heart design on it.

And drew attention to the swirly-heart design on the massive diapers she was wearing. “And if you want to know where to go, then you should pay close attention.”

“Oh, are you going to show us where it is?” Celestia asked.

In reply, the dragon swayed her diapers back and forth.

Back and forth.

“Hatchlings being in the nesting grounds is where they should be,” the dragoness said. “So hold still...”

The two hatchlings stared, as the dragoness got closer. Then, suddenly (and in a way that the really should have expected) the pretty swirly-spiral-heart diaper went floomph down on top of them both!

“And remember to love diapers,” they were told.

"Love... diapers..." Luna mumbled as the two princesses were nuzzled, cuddled, caressed and crinkled... and did a bit of nuzzling back of their own!

Though after a bit, the pink dragon got up, looking suspiciously at a purple-black dragon that was approaching. And while neither Luna or Celestia could figure out why, the new dragon, a different one from the one they'd met on the boat, seemed like trouble.

"Oh good! Two little hatchlings here to watch my diabolical plot!" the sable dragon grinned, a collar around her neck with a shiny gem in the middle, and a matching gem on her tail that waved back and forward. "Prepare yourself! The biggest, poofiest diaper butt will win!"

The pink dragon gulped, her heart diaper not looking quite as thick as the purple dragon's gem diaper. The two turned to face their rears at each other, diaperbutts shaking in a dazzling display of swirly colors and poofy pamps that made Luna and Celestia all dizzy... and as they watched, the pink dragon's diaper began to slowly sag and yellow as the pink dragon's eyes became all swirly... she hadn't had the poofiest diaper butt after all!

"See? Subby soggy dragons get dominated by bigger, poofier dragons! And all dragons love diapers, so they have to look when their foe is shaking their butts casting powerful spells at them!" the purple-black dragon said, putting a leash on the pink dragon and tugging her along. "And, while you two were distracted, I added more diapers to you too~" She grinned.

Luna and Celesia gasped in surprise – their diapers were even thicker now, with a new purple diaper with a big gem shaped locked print on it now adorning their behinds as an extra layer.

"If you want to be rid of my evil diapers, you'll have to brave my Pillowfortress!" The black-and-purple dragon cackled, leading the soggy, subby pink dragon away by her new leash~

“Oh no!” Celestia gasped, sitting back on her haunches, and tried to take the evil diaper off – to no avail. “What do we do?”

“I know what we have to do,” Luna replied. “We need to… um… well, we need to get into that Pillowfortress!”

“Well, of course!” Celestia shot back. “But I mean, what do we do once we’re in the Pillowfortress?”

Luna thought about that.

“Why, brave it!” she replied. “Of course… admittedly, I don’t have any more details, but it’s not like I would have any more details. I don’t know what it’s like in there, so I can’t make any plans.”

“That is a good point,” Celestia conceded. “All right, sister… if you’ve got such a good plan and a good point, where do we go to get to the Pillowfortress?”

“Well… we could follow that dragon,” Luna replied. “Wait, uh… where did she go?”

She flew up into the air, hovering, but couldn’t see any sign of where either dragoness had gone.

Though she did spot something else, and flew down to look at it.

“Look!” she said. “This is very strange, but I think… Celly, I think this is a map!”

“It can’t be, can it?” Celestia replied. “It’s not on a diaper.”

“No, I guess not,” Luna admitted. “But it’s similar, right? Look here!”

She pointed with one of her clumsy dragon-paws at the Nesting Grounds, which had helpful little writing saying that Ember the Pink lived there. (That took both hatchlings a moment to think about, because they were sure they knew an Ember who was blue, but they couldn’t remember any details about her.) Then the sort-of-map also showed a Pillowfortress, home of Cynder the Evil, and a sheep pasture nearby which was an odd thing to have as the only other detail on the island.

“Well, we know where to go!” Celestia decided. “Let’s hurry there!”

"Right! I'll take the not-map with us so we don't get lost." Luna said as the two waddled (very slowly due to how thick their diapers were) towards the pillowfortress on the map!

After getting lost a few times and distracted by pretty swirly flowers and puffy powder pollen, they arrived at the front gate of the massive pillowfortress, the big, poofy pillows stacked up tall with big blankets over the top, and a heavy weighted blanket draped over the entrance so they couldn't waddle inside.

"Hmmm... we need to get in there!" Luna said, noticing some sort of lever with a big basket next to it with a sign that read "Put your sheep tribute here. Provide enough, and I'll let you in to admire my pampered butt - Cynder."

"So we need sheep... like those?" Celestia said with a slightly confused look, pointing at the packs of swirly diapers with the word Sheep nearby. They looked... odd, but neither princess could really explain why.

"I guess so... we just fly, scoop them up and drop them in the basket?" Luna said, taking shaky, wobbly flight she swooped to pick up the "sheep", trying to not get too dizzy and ditzy from all the swirls.

The first pack sheep hardly moved the lever at all! They were going to need lots of "sheep".

Celestia picked one up, then Luna, the two of them trying to ignore the swirliness on the ‘sheep’ to focus on what they were doing and make sure they caught the sheep as they tried to run away.

For some reason they kept overestimating how fast the sheep were moving, and tumbling over and over in a trip or fall which meant their diapers crinkling and their wings getting tangled up, but none of the crashes were bad enough to mean they needed a replacement tailfin or anything of the sort. Instead, they slowly got better at snagging the sheep from the air, without needing to actually land… and that turned into racing to see who could get more sheep first.

Into competition, over who could collect more swirls and more diapers sheep and who was being a more greedy dragon over getting their diapers sheep all collected together.

Back and forth they flew, delivering more and more tribute for Cynder, hunting down more and more sheep and getting more and more focused on picking up swirls and carrying them around and being weighed down by the thick padding of the… sheep.

“I’ve got twenty-nine!” Luna said.

“Well, I’ve got…” Celestia replied, frowning. “Twenty-eight? No, um, I’ve got twenty-nine too!”

“Are you certain?” Luna asked. “It sounds like you might not be certain at all! Or maybe like you just made up that number!”

“Well… shut up, that’s what!” Celestia said, grabbing two at once, and her wings strained as she carried them along. “If I put these in, I’ll definitely be in the lead!”

“Not if I carry two at once as well!” Luna replied, picking up threeswirly diaper packs sheep at once. Then Celestia picked up another one, and so did Luna in retaliation, and they staggered through the air before crashing into one another just when they were about to drop their prizes into the basket.

Meaning that they ended up buried in ‘sheep’, until the two of them squirmed their way out of the pile.

“That was your fault,” Celestia muttered.

“Was not,” Luna replied, then pointed. “Look! The blanket’s open!”

"I totally won!" Celestia said as the two started to waddle into the pillowfortress.

"Did not! I won! I carried the most sheep at once!" Luna protested!

"But I made more trips to get sheep!" Celestia argued, the pair more focused on bickering than on where they were going.

A few seconds later that proved to be a mistake, with both princesses dragons falling into a magic blanket pit with matching yelps of surprise, blanket snakes wrapping around their limbs to prevent them from flying or wiggling away!

"Aha! You fell into my trap!" Cynder giggled, waddling to the edge of the pit. "And now, to inspire an adequate sense of diaper doom to both of you, look at my diabolical trap in action!" she said, pointing to the side where a blanket divider fell down, revealing Ember getting tickled silly by feathers and blanket snakes as she squirmed and squealed in laughter, the poor dragoness getting soggier, sillier and subbier. For dramatic effect, Cynder waddled over and blew a big raspberry on Ember's tummy, making her even more silly and squirmy and giggly.

Only a moment later Luna and Celestia saw the tickly feathers and blankets heading towards them, sloooowly drawing closer as the diabolical but slow acting trap activated.

"Soon, I'll have two more subby soggy dragons in my hoard!" Cynder grinned.

"...Why is the trap so slow?" Luna asked. "Isn't this ineffective?"

"It's for dramatic effect and suspense!" Cynder said, sounding a bit miffed.

“Then… we might have time to get out of here,” Celestia decided, trying to flap her wings, then realized that those very wings were wrapped up in blanket snakes. “Oh, um… no, can’t do that… maybe… can we squirm free?”

“You’re talking about how to escape my trap in front of me!” Cynder pointed out. “That’s not very clever of you! That must just mean that you’re a silly victim!”

“That’s not how- how is that how it works?” Luna demanded. “Where else are we supposed to talk about how to escape?”

“You’re supposed to not escape!” Cynder said. “That’s why it’s an evil trap! I don’t have to give you a fair chance!”

She laughed, evilly. “Anyway – you’re as unable to escape as you’re unable to escape your diapers! Though, maybe it’ll help you escape if you watch my tail…?”

Turning, Cynder waved the dangly gem on her tail in front of them, waving it back and forth. And back and forth.

“Back and forth…” Celestia mumbled… then she squirmed suddenly, realizing that she’d been staring for too long!

It had only felt like a moment, but the feathers and blankets were almost there! If she was going to escape at all she was going to have to do it right now!

Celestia, getting a moment of inspiration, cast a spell that would make her "loose". If she was loose, then surely that would let her slip right out of the trap and take on Cynder!

She concentrated, wiggled her body to cast the spell and then...

Cunder's giggling and a rapidly warming diaper made a very blushy Celestia realize she should have been more specific in what she made loose when she cast her spell...

Luna on the other hoof paw tried to cast a spell that would make her very powerful, wanting to become so powerful she could just rip her way free!

Luna did her best to concentrate, but her spell took a bit longer to cast, and her concentration wavered as the tickling started just as she cast the spell...

Luna blushed as she felt her diaper growing soggy, ripping away any restraints covering her diapered rear, but unfortunately that wasn't quite what she wanted...

"Uh oh, looks like you were too slow!" Cynder grinned as the blanket snakes and feathers reached the two trapped princesses dragons, sending them squirming, squealing and soaking with silly tickles, and Cynder waved the dangly gem at them just so they didn't get any funny ideas about escaping.

“Subby, soggy dragons listen to bigger, poofy dragons, remember,” Cynder told them, with a smirk. “And clearly you’re subby and soggy, while I’m bigger and poofy! Isn’t that right?”

Both of the hatchie-furies were too busy giggling and staring to answer, but it was clear that they agreed anyway. They were soggy, obviously, and they were subby, and they were staring at the swirly gem, and they were trapped in Cynder’s evil diapers too!

It was all a kind of tangled up knot of obedience and giggles, wings and paws all snarled up and diapers squishing as they squirmed…

...until there was a thump sound, and something caught their attention. Not just Luna and Celestia, but Cynder as well.

Ember was too deep and dozy and ditzy and hypnotized to even notice, but both sisters gasped at the sight of a new dragon! A big, puffy diapersuit dragon, one with a purple and yellow hide and a pair of springy horns and a proper alicorn horn between them and a springy tail, and orange wings, and who had amused ice-blue eyes, and a massive diaper with a sort of night-time theme to it – including a crescent moon design on the front and the back.

“Gasp!” Cynder gasped. “Spyro the dragon!”

“That’s right!” the pony dressed as Spyro agreed. “I’m here to rescue these dragons from your evil ways!”

Cynder picked up one of her evil diapers, flinging it at Spyro, and he just stood there and let it wrap around him… then it glowed, and changed so it had the same design as the one he’d been wearing before.

“Nightwear diapers are better than any other diapers!” Spyro announced. “That’s because Nightwear is best!”

“Nightwear is-” Cynder repeated, automatically, then shook her head. “No, I didn’t mean to say that! You can’t beat me!”

Cynder went waddling over to another blanket wall and tugged it down dramatically, revealing a big, swirly, shiny gem swinging on a chain!

"Ha! You'll never resist my swirly gem trap! It turns heroes like you into soggy, subby dragons!" She declared, only to see that Nightwear Spyro... wasn't being affected.

"Silly hatch, Nightwear diapers make swirly gems traps stop working! Take a look for yourself, the gem does nothing." Nightwear Spyro smirked.

Cynder huffed and looked at the gem as it swung back and forward, making her feel all dizzy and ditzy.

"I-it seems to be working?" Cynder stammered, only to look back at "Spyro" and see them still unaffected.

Luna and Celestia kept looking between the silly swirly gem and "Spyro", getting more dizzy and confused every time to looked at the gem.

"No it's not. You can see it going back and forward, back and forward, shiny, sparkly, soggy." "Spyro" said, and Cynder bit her lip as she felt her padding grow damp.

"N-not... a..." She started to protest, only for Spyro to waddle over and give her soggy diaper a biiiiig squish.

"Subby dragons wear soggy diapers. This diaper seems veeery soggy. And that makes you a..?" "Spyro" asked.

"...Subby, soggy, squirmy dragon?" Cynder blushed, rewarded with more diaper pats.

"Very good!" "Spyro" praised, letting the dragons watch the sparky gem swing back and forward...

Celestia squirmed, as the gem and the words and the spirals all spiralled around and around and around in her head. Spiralling spirals making her dizzy, especially with how one of the things in the spiral was a spiral, and she absorbed the messages… subby dragons, soggy diapers, subby soggy squirmy dragons…

She was a good obedient dragon, and Nightwear was the best… the thoughts etched themselves deeper as Cynder’s trap fell apart, dumping her and Luna out in a tangle of plush-suit limbs and squishy diapers.

It took Luna three tries just to stand up, but before she’d got much further Spyro was padding over and putting down a pair of opened Nightwear diapers in front of her and her sister – big diapers big enough to go over their evil diapers from Cynder.

“Um…” Luna began, staring at the diapers, and her head felt dizzy and foggy. “Are… those for…?”

“Yes, they’re for you, of course,” Spyro replied. “The best way to not be controlled by evil diapers is to replace the evil diapers with Nightwear diapers so they can do it instead, of course. Then all you need to do is to make sure you’re less squirmy.”

Spyro stepped back. “But first, you should put your rumps over those Nightwear diapers, and sink your rump down onto them.”

Luna waddled forwards, nodding vaguely, and then let her padded butt sink down into the soft embrace of the Nightwear diapers.

Surrendering to them…

Once they had both sunk deeeeep into the Nightwear diapers, the tapes secured themselves so they had even thicker, poofier rumps.

Nightwear was the best... soggy dragons were subby dragons...

Celestia blinked as she looked around the room: for a moment, she though there was two Spyros in the room, one looking much more ditsy and dizzy then the other... then it was just one Spyro wearing the thickest Nightwear diaper of them all.

Nightwear was the best... subby dragons were squirmy dragons...

Luna found herself squirming around, feeling all blushy and huffy and squirmy and soggy as Spyro waddled up to her with his big Nightwear pamper. It had Nightwear's face printed on the butt and front, horn glowing with buzzy magic that was making Spyro all pokey.

Nightwear, now in her diaper form instead of wearing a plush suit of Spyro, smirked when she saw all the squirmy dragons.

"Good subby dragons know how to smooosh and squiiiish all the squirms away so they're just Subby and Soggy!" She declared as Spyro plopped his Nightwear diaper against Luna's rump and started to hump.

Nightwear was the best... Sink into the Nightwear pamps and hump the squirms away…

“...mrf,” Luna mumbled, squirming, then blinked a few times and blushed.

She felt… really soggy, and squirmy…

Her sleep-fogged mind had trouble focusing, or remembering… she’d dreamed about, something, she thought? But the details weren’t very clear…

Crawling out of her bed, past the diapered black-dragon plushies under the covers – one with pretty multicoloured wings, one with a collar, and one night-fury – she mumbled something, then yawned, and went to go and change herself.

Celestia got into the changing-room just ahead of her, her magic holding her own set of purple-and-pink-and-white diapered dragon plushes bundled up in her blankets, and Luna grumbled.

“I’m sure I should be first,” she said.

“You snooze, you lose,” Celestia replied. “Besides, I need a change after how soggy I got last night.”

“You think that’s unique to you?” Luna asked. “I find it hard to see how anypony could have a soggier diaper than this…”

"Oh fine, get on the changing table, soggy butt! Otherwise you'll leak over the floor." Celestia huffed, both of their diapers quite yellowed and saggy between their legs, the hefty, warm, soggy squishes reminding them just how soaked they were.

"Another rain cloud for the potty chart I suppose..." Luna grumbled, not even sure why they had a potty chart in the cottage nursery. It wasn’t like they ever made it.

After a bit of magic to get Luna changed and the princesses swapping places, the now clean and crinkly mares went to the pool to relax again, sipping on lemonade and enjoying the sun.

"You'd think the princess of the sun would have at least some sunshine stickers on her potty chart." Luna teased her sister, which made Celestia blush a bit.

"Oh shush you! You're still the queen of bedwetters," Celestia said. "That's why you wanted to go first on the changing table today, right?"

Luna blushed, having not expected a strong retort. "W-well that's because I'm trying to lead us through those dreams! We still need to find where Nightwear is, we only found clues last night," Luna pouted.

"Well little sister, I'm sure we'll find Nightwear sooner or later to figure out if they'll have any odd effects on us. Just be sure to order more of those thick nighttime diapers for us tomorrow before we run out. We don't want any puddles at night." Celestia said.

"Yes sister..." Luna sighed. Being a princess was hard… it was always so hard to potty train…

With guest appearances from various Spyro characters, plus an entrancing swirly-winged dragoness who’s appeared in a previous joint story (but which featured no ponies).

Third Night – Wonderbutt Dream

“All right, let’s try this again,” Luna said, once they were in the dream realm. “I’ll just link myself to your dream, and we’ll see where you end up going.”

“Why me?” Celestia asked. “Why not try to see where you end up going?”

“I am the Princess of Dreams!” Luna said.

Then coughed.

“Was, the Princess of Dreams,” she amended. “So I should be in charge… but if you insist, I’ll link you to me and then we’ll see where my dream ends up going.”

“Oh, so there actually wasn’t a reason?” Celestia said, with a shrug.

Her diaper crinkled, and Luna frowned slightly. Something about this was… odd. Unusual. It wasn’t quite what she was expecting…?

She shrugged her wings, unable to work out what the issue was, then linked the two of them together with a magical tether and cast a spell to shuffle them into a random dream.

Whatever it was, the Nightwear memorial should be there somewhere…

...Celestia trotted through the door of the school-house, then held the door open with her big crinkly diaper-butt to let Luna in after her.

“Ah, good,” the teacher said. “I’m glad to see you two have arrived on time. You were nearly late!”

“I wouldn’t want to be late,” Celestia admitted.

“Nor would I,” Luna agreed. “But we aren’t late, so we don’t need to worry about that.”

The teacher smiled. “That’s right,” she said. “There’s a lot of things you don’t need to worry about. In fact, that’s what this lesson is about…”

"Um... what lesson are we here for again?" Luna asked with a bit of a sheepish blush as she looked around to see what the lessons were about. The words on the chalkboard said something, but Luna was finding it hard to understand what it said...

"You're here for Wonderbutt training of course!" the teacher said, sounding suspiciously like Nightwear Luna didn't recognize the voice, the large alicorn was wearing a Wonderbutt costume and a big, poofy diaper, but the outfit prevented either princess from telling who the teacher was.

"O-oh... um, we're actually needing to look for a statue..." Celestia said hesitantly, not wanting to get drawn into a long class when they had a goal for tonight. Plus the name seemed a bit off from what she remembered..?

"That's why you're here to be a Wonderbutt! Wonderbutts learn how to travel fast in big, poofy pampers and show off their crinkly butts find things! You two are wearing thick, poofy pampers already, so you're clearly Wonderbutts in training!" the Teacher said. "Now get ready for class and put on your Wonderbutt uniforms!"

"Oh... well if it will help us be faster later..," Luna said, putting on the tight fitting outfit that left nothing to the imagination, her poofy padding included.

Celestia did the same, and the princesses hesitantly took their seats. "So... where do we start?" Celestia asked, just as their goggles started to turn shimmery and shiny and swirly.

"The first rule of being a Wonderbutt is to obey," the teacher giggled.

“S-so, umm… how do we…?” Luna tried asking, not sure if she should focus on the goggles or focus on what she wanted to learn, or even both. The goggles were so distracting, but… were they part of the lesson or not?

She wriggled back and forth a bit, settling in for the lesson.

“Oh, it’s quite simple,” the teacher told her, and by extension also told Celestia. “Actually, learning to obey is more about learning how to not do something. The simplest thing to do is to obey, to do what someone tells you to do. But to think about it is much harder, and that’s something you’ve learned to do for a long time… but to obey you just need to learn how to not think about something first. Just do it before you have time to think about it.”

Celestia frowned, through the swirling patterns. “But… isn’t, thinking about something good?”

“Not if you’re going to be a Wonderbutt,” the teacher said. “Imagine what it would be like if the head Wonderbutt told you to do something and everyone thought about it first! They’d all go in different directions and wouldn’t act in time, and it would be complete chaos… but low ranking Wonderbutts listening to someone who’s higher ranking than them makes sense, doesn’t it?”

She chuckled. “Of course, I understand it’s going to take a while to learn that. So we’re going to start with some simple lessons… if you’re having trouble thinking, just focus on the goggles and their patterns, it’ll help you stop thinking. But first, here’s what you need to repeat after me… Wonderbutts don’t think. Wonderbutts obey.”

“Wonderbutts don’t think,” Luna repeated. “Wonderbutts obey...”

"Wonderbutts don't think," Celestia said as she followed along, "Wonderbutts obey..."

"I'm a trainee Wonderbutt," the teacher said.

Luna and Celestia nodded along: that made sense after all, they were in class right now.

"I'm a trainee Wonderbutt," they repeated.

"Everyone outranks trainee Wonderbutts," the teacher said. That made sense: trainees were just learning after all.

"Everyone outranks trainee Wonderbutts," the Princesses Wonderbutt Trainees repeated.

"I'm a good Wonderbutt," the teacher said, making Luna and Celestia feel all fluttery. They were good Wonderbutts, right?

"I'm a good Wonderbutt!" Celestia and Luna said together enthusiastic, earning pats on the head.

"Good Wonderbutts Let Thoughts Flow Out," the teacher said, turning around to display her rump as she relaxed, a gentle pssssshhhhh letting the pair know their teacher was really good at letting all those pesky thoughts flooooow out, her Wonderbutt onesie uniform snaps popping open one after another to reveal a soggy swirly diaper that was getting bigger, soggier, squishier, swirlier... and the teacher began to shake her rump from side to side, drawing in Luna and Celestia's gaze as they felt their own diapers growing warm as they let the thoughts flow out...

Neither Celestia nor Luna was paying much attention to how many times they repeated their instructions. That would have been thinking, not obeying, and they knew good trainee Wonderbutts didn’t do that.

So there was just a haze of soggy dizzy obedience and repetition, over and over again, letting the lesson sink in…

...until there was a bright flash in front of them, as a TV turned on.

“Now, since you’ve been such good Wonderbutt trainees,” the teacher said, making both Celestia and Luna squirm with happy obedient thoughts… “...you get to watch the next bit of the lesson about what Wonderbutts do as a cartoon!”

She clicked the remote, and a colourful cartoon spiral appeared counting down until the lesson began.

A cheerful little cartoon-Nightwear appeared on the screen, telling them to listen closely like good Wonderbutts, because she outranked them, and the addled alicorns accepted that easily. Then the cartoon began talking about the duties of Wonderbutt trainees, and how they flew around and listened to anyone who outranked them and watched out for sneaky infiltrators who might try to steal Wonderbutt diapers secrets and obeyed and wore whatever they were told to wear and obeyed...

As they watched the swirly, shimmery show, Luna and Celestia gradually waddled closer and closer to the screen, letting thoughts flow out, listening like good Wonderbutts...

And just like that, they stepped through the TV screen and into the show itself! Above them, they could see the screen of the TV leading back into the class room, the view mostly occupied by a swirly giant Wonderbutt with a moon print on it that lit up the night, the shifting, soggy moon making the lighting and shadows dance ever more swirly, shifty and dizzy...

"Wonderbutts!" a voice said, belonging to Spitfire Soggfire, the commander of the Wonderbutts! Her Wonderbutt uniform had a thicker, poofier diaper then they did, clearly marking her as the leader. (Everyone outranked trainee Wonderbutts, after all.)

"Yes Ma'am!" Luna and Celestia said, trying to stand as much to attention as their swollen, sloshy diapers allowed.

"We've heard news that Shadowbutts, Pooffins, Sissybutts, Draaagons and Changlings are coming to steal our diapers secrets! Your task for today is to Submit guard the diapers secrets and obey repel anyone who comes to steal them!" Soggfire said.

"Yes Ma'am!" Luna and Celestia said, then Celestia paused.

"Um, what are Poofins and Draaagons?" Celestia asked sheepishly.

"Poofins are Poofy Griffins, and Draaagons are Diaper Dragging Dragons silly! Now go to the vault and look for swirls trouble!" Soggfire commanded, the two Wonderbutt Trainees heading to the easy to find super secret hidden vault to Soak and SubmitStand guard!

“So… how exactly are we going to be able to tell any of these infiltrators if we spot them?” Celestia asked after some minutes, frowning.

“I guess… that’s why we need to be alert?” Luna replied. “Uh, if it was easy to spot them then they wouldn’t need us on the case, right?”

“Right, but if it’s really hard then how do we know if we’ve spotted them at all?” Celestia replied.

Luna considered. “Well…” she began.

“And how do we know that there isn’t one creeping up on us right now?” Celestia added. “We can each only look in one direction at a time… what do guards normally do?”

Luna shook her head. “I don’t actually know,” she admitted. “I was hoping you had an idea?”

“I think guards normally… patrol, right?” Celestia suggested. “That sounds like something guards do. They go back and forth, and, uh, march around, so they can check everywhere. Instead of standing there and waiting for someone to show up.”

“That’s a good point,” Luna said. “But we don’t want to leave this place without anyone defending it… what about if we take turns?”

“Taking turns!” Celestia agreed. “That’s a great idea – let’s do that! So… who goes out on patrol first?”

One coin flip later (Celestia had picked ‘butt’), Luna was out on patrol, her horn lit up as she waddled back and forth down the corridors of the super secret hidden vault.

“I still don’t know what I should be looking out for,” she muttered, under her breath, turning left and then right as the glow from her horn lit up the corridors.

Then she saw somepony moving up ahead.

She almost shouted, but the other pony wasn’t moving very fast and they didn’t seem to have noticed her. So she waddled up more quickly, getting a spell ready, before seeing that it was a stallion in a Wonderbutt onesie.

“Oh, it’s… what’s your name?” she asked. “I was worried you were an infiltrator.”

“I’m Shadowy Secrets,” the pony replied, smirking and wiggling his butt. “And you don’t need to worry about that.”

“I’m not,” Luna said. “...should I be worried?”

“Not at all,” Shadowy Secrets said, wiggling his butt again, and the poppers holding the flap of his onesie strained… then popped off, revealing that he was wearing a second onesie under his Wonderbutt onesie!

This one was a much more sinister, purple-and-yellow, Shadowbutt onesie, and it had a swirly pattern on it as well!

"O-oh!" Luna said, knowing she had to submit guard the diapers secrets from being stolen! "Well, um, you don't look like a Wonderbutt! So you have to go!" Luna said.

"Of course I have to go~" Soggy Secrets said, relaxing as his diaper began to warm and swell, the Shadowbutt onesie looking bigger and bigger as the diaper underneath expanded until it popped open, hitting Luna with a dizzying puff of powder. "You have to "go" too. After all, my diaper is bigger and heavier then yours. How are you going to guard if you can't beat me in a bump butt contest?"

"Have to... go..." Luna mumbled, her diaper growing even warmer and soggier as she felt her diaper swell even further.

"That's right! Now your diaper is even bigger and heavier then mine! But you have to defeat all the Shadowbutts, right? How are you gonna defeat the Shadowbutts if they know a Wonderbutt is coming?" Soggy Secrets smirked.

"Um... I'll just defeat you and figure out what to do next!" Luna said, trying to butt bump Soggy Secrets with her saggy rump, connecting with a SQUIIIIISH that made Luna feel all subby and squirmy, letting Soggy Secrets easily sit on top of her.

"I think you'll be a more fun Shadowbutt then a Wonderbutt~" Soggy Secrets giggled, layering Luna into another, extra poofy Shadowbutt Diaper and her very own Shadowbutt suit, the goggles already making shimmery swirls…

By the time Soggy Secrets had finished diapering- and suiting-up Luna, he smirked. “Oh, but you’re going to need to make sure you don’t get noticed as a Shadowbutt by that Wonderbutt guard, aren’t you? So if you’re going to infiltrate, you need a Wonderbutt disguise!”

The swirly goggles made it hard to impossible for Luna to think of a counter for that, and within a minute Soggy Secrets had fitted her with a disguise as well – a clip-on name badge that said Not A Shadowbutt.

“Remember, don’t tell anyone you’re really a Shadowbutt!” Soggy Secrets added. “A secret Shadowbutt!”

With that, he rump-bumped Luna back down the corridor, and Luna waddled along with her rump and name badge swaying from side to side…

“Luna!” Celestia said. “I see you’re back from your patrol!”

She frowned. “Are you all right?” she asked. “You look… different.”

“Like what?” Luna replied, tilting her head.

“Well…” Celestia began. “Like a Shadowbutt, maybe?”

“But I’m obviously not,” Luna replied, sitting back in her Shadowbutt sleeper with its Shadowbutt cutie marks on her flanks and Shadowbutt colouring and swirly Shadowbutt goggles

She raised a hoof, and tapped the name badge with its reflective purple-yellow-black swirl background. “Look!”

Her hoof made it swing back and forth, and Celestia leaned closer to look for a minute moment.

“..well, that does say Not A Shadowbutt,” she conceded. “All right, so you’re not a Shadowbutt, but… keep an eye out for them, I guess?”

Celestia frowned, thinking about whether she should stay, then shook her head.

Obviously she needed to go out on patrol, now, and nothing was wrong, was it?

Not far away, another royal was... very confused when she looked around. Queen Chrysalis wasn't sure who's dream this was, but it didn't seem to be one of hers. And why was there a giant soggy diaper butt shaking back and forward and back and forward and back and forward...

Queen Chrysalis Crinklesalis blinked after a bit, realizing she'd gotten distracted from her mission! She had to steal diapers secrets from the Wonderbutts, and find Wonderbutts to turn into cute, rubber suited changeling drones!

So she began to waddle towards the totally obvioussuper secret vault, trying to find a guard on patrol she could pounce on...

"Halt!" Celestia said, spotting the Changeling Queen waddling towards the vault. "Um... go away! This is for Wonderbutts only!"

Queen Crinklesalis grinned, pouncing on Celestia and tickling her sides, making the Wonderbutt flail and squeal in laughter as her padding began to drooooooop from a heavy soaking.

"Looks like you're in need of a changing! And, because I'm a changeling queen, I get to change you!" Crinklesalis giggled, changing Celestia's pamp to a big, black, rubbery diaper that began to spread on Celestia's body.

“H-hey!” Celestia protested, in between giggles, as the diaper’s rubbery-crinkly coating spread out across her body. “That’s not – stop it – you’re not supposed to do this!”

“Really?” Crinklesalis replied. “Then how am I doing it?”

“That’s not…” Celestia said, then got distracted as Crinklesalis lit her horn and her eyes began to glow green.

The spiralling, entrancing green patterns caught her attention… and, also, Queen Crinklesalis’s attention, because she wasn’t actually immune to her own hypnosis. Just… resistant.

If Crinklesalis was dizzy, though, Celestia was entranced… at least, until she felt her hooves coated in the rubbery-crinkly material!

She waddled backwards, falling over and landing with a crinkly springy sound on her black-diapered rump, then got caught up in Crinklesalis’s eyes again and felt dizzy all over again.

“Listen closely,” Crinklesalis said. “You are a change-ling.”

“I’m a… change-ling,” Celestia repeated.

“Change-lings don’t think,” Crinklesalis told her. “Change-ling drones don’t think. Change-ling drones just obey.”

Celestia nodded, blushing, as the drone-suit finished forming over her.. encasing her eyes behind green swirls.

“But Change-lings can disguise themselves,” Crinklesalis went on. “They’re great at infiltrating and pretending to be someone.”

She pulled out a Celestia suit, frowned for a moment as she wondered where she’d got it, then caught sight of the moon mooning her and stared at it for a minute a few seconds. Then shrugged.

It wasn’t important, anyway.

The black rubbery suit covered Celestia from head to toe, the rubber squeaking and squeezing her, the poofy, rubbery diaper underneath filling the suit with dizzying powder.

Over the squeaky suit, Crinklesalis promptly put her in a Celestia outfit, the Change-ling drone underneath it now suffering from yet another layer of swirly goggles and big, puffy pink pampers that pooofed out pink powder with every step, making her even more silly and dizzy and obedient.

"Now my little Change-ling drone, go and steal the diapers secrets from the vault! And when your diapers are all soggy and soaked, waddle back to the Queen of Change-lings for changing," Queen Crinklesalis instructed.

Celestia could only give a little "mrfff!" in response, fully encased in rubbery, plushy suits as she was, but she obediently toddled towards the vault, try to remember how to steal diapers instead of how to be a big dumb diaper drone...

At least it would be Luna's turn to patrol next.

Luna was still looking at the vault, wondering how to open it, when she heard a squeaky, creaky noise from the left.

She looked up, and saw…

saw…

A blushy, poofy, squeaky rubbery suit wearing-

A bad Celestia costume-

...her sister, waddling up after finishing her patrol.

“I wasn’t trying to get into the vault!” Luna said, jumping.

“Mrf,” Celestia replied.

Luna tilted her head a little, not sure why her sister wasn’t saying much, then shrugged.

“Well, I’ll… go on patrol,” she said. “And, definitely not try and work out how to get into the vault!”

“Mrf!” Celestia nodded, head wobbling a bit, and squeezed her diapers with her hind legs.

Satisfied, Luna trotted off.

“...what?” Luna asked, some minutes later.

She looked around.

No mistake, this was definitely the route… but it went through the water?

And if Luna went though that water, she wouldn’t be a Wonderbutt who was really a Shadowbutt who was really a Wonderbutt who was really a Princess. She’d be a Soggybutt.

Then she heard a shout, and saw a hippogriff with a pink coat and blue mane do a perfect swan-dive into the water.

“Wahoo!” the hippogriff announced, splashing to the surface again, and shook herself out. “Diving’s great! And, get this – there are stairs up to the diving platform!”

“...do I know you?” Luna asked.

“Oh, probably not,” the pink hippogriff replied, sitting down on her moon-themed diaper. “I feel like I should know you! But when I look at you, all I can think of is the moon?”

Luna looked up at the mooning moon, and so did the hippogriff, and a few minutes seconds later Luna shook her head in confusion.

“Oh, I’m Silverstream!” the hippogriff added. “I’m sort of a princess, only it’s because the queen is my aunt, not my mom. So my mom’s a princess and so am I. Funny, huh?”

She shrugged. “Anyway, you have a problem, right?”

“Yes,” Luna agreed. “There’s water across the path I was taking.”

“Oh, that’s super easy to deal with!” Silverstream told her. “See, hippogriffs are also seaponies!”

She giggled. “And that means, all you need is to disguise yourself as a seapony, meaning a hippogriff, and the water will know not to get into your diaper!”

Luna was nodding along. If she wore the outfit, she'd be extra under cover! No-one would realize she was a Shadowbutt! So when Silverstream offered the suit, Luna wiggled her already poofy and suited bottom into the new puffy suit and diaper... and almost immediately started to potty dance a bit.

The new suit was all slick and squeeezy, and it was squeezy right on her bladder, and it filled her head with Soggybutt thoughts as the head began to glow with more hypnotic swirls.

"So I just... go across the water?" Luna asked, even more dazzled then before.

"Yup! It's easy!" Silverstream said, guiding Luna to the water.

The suit immediately got even puffier and poofier and squeezier as it inflated to keep Luna above the water, the inside filling with powder as Luna was filled with silly, sloshy, ditzy, dizzy thoughts.

After idly paddling around, she sorta washed up on shore, and in a bit of a daze (and much soggier) she waddled to swap out patrol with Celestia…

Celestia-drone hadn’t had much luck thinking of a way to get in to steal… whatever it was she was supposed to steal.

She hadn’t had much luck thinking in general, really. But she did see when her sister arrived, and looked up in vague confusion.

She didn’t remember Luna being that shiny. Or sloshy.

“I’m, mrf, back,” Luna said. “So… your turn to go and patrol.”

Celestia nodded. “Mrf,” she said, trotting out to go on patrol herself, not questioning the instruction because it was like an order and… it was easier than thinking of what to do herself.

As she waddled along, Celestia looked back and forth, then nearly ran into a pink poofy diaper.

The pony wearing the pink poofy diaper turned around, then sat down with a puff of foal powder. “Oh, good, you’re here! Auntie Celestia, I had some new diaper designs for you to try out – say you’ll try them on!”

“I’ll try them on,” Celestia agreed, automatically, the pacifier falling out of her mouth as she opened it for the first time since meeting Chrysalis, then blinked a few times as she tried to focus. “Cadance, what’s-”

“Oh, I’ve been thinking about making my own Butts team,” Princess Cadance replied. “The idea came to me in a dream… last night? Or maybe it was tonight? I’m not really sure…”

The pink princess shrugged her wings. “Anyway, the idea I had was, if you have the Wonderbutts and Luna has the Shadowbutts… I think that’s right?”

Celestia was sure there was something worrying about the Shadowbutts, but Cadance kept going. “Anyway, I tried to think what mine should be, and of course I’m the alicorn of love so it only seemed right to call them the Sissybutts. But I trust your opinion, so could you try this on and see how comfy it is?”

"Of course," Celestia said automatically before realizing she may have spoken too soon... but what was the worst that could happen?

So she waddled over to the Sissybutt uniform Cadance had laid out, and started with the big, poofy pink diaper. By now her padding was becoming absurdly thick and clumsy to move in, and the cute puffs of pink powder made her feel all subby princessy.

"The diaper is very soft and comfy... it makes me feel more like a princess," Celestia said with a blush hidden by her many uniforms as she moved onto the suit. The suit was an even more frilly and pink addition to her outfit, covered in cute ribbons and bows that made her want to wiggle shyly from just how over the top and cute it was. In fact, she did wiggle shyly, making her outfits and diapers crinkle and rustle adorably.

"Do you think it needs more frills and bows?" Cadance said in concern.

Celestia shook her head again. "Um, no, this one is already cute and plushy and soft enought I think..." She said as she put on the swirly mask, knowing the booties would make doing anything harder.

Immediately she was bombarded by more pink Subby, horny princessy swirls that made Celestia feel all flustered and even more squirmy... and when she added the booties, she blushed even more about the fact the hind legs were slippery, and kept her legs spread apart so every could see her humpable royal behind.

"I-I think this uniform will be perfectly cozy and comfy for the Sissybutts…" Celestia said, getting rather dazzled by the all the swirls in her many uniforms…

“Excellent!” Cadance replied. “Which means that, since you’re wearing a Sissybutt uniform, you must be one, yes?”

“...um,” Celestia said, confused, but the swirls on top of swirls on top of swirls were confusing her a lot.

“Yes,” Cadance went on. “You’re a Sissybutt, and Sissybutts do what I say! Because I’m the Princess who’s in charge of them.”

Celestia nodded, a bit confused, but Cadance seemed to know what she was talking about and good… drones?Wonderbutts?Sissybutts did what they were told.

“So, to make sure my Sissybutts are as good as they could possibly be, I order you to go and steal the diapers secrets from the vault! That way I’m sure that the Sissybutts will be as good as I need them to be!” Cadance finished.

“Yes, Ma’am!” Celestia said, saluting, then fell over onto her rump as she slipped on her slippery booties.

Trying to get upright led to her slipping over again before she finally got all four hooves under her, and she waddled off uncertainly.

And giggling.

“How come this isn’t… working?” Luna asked, then heard a giggle and turned quickly away from the vault.

Celestia was waddling-and-blushing her way towards her, and Luna tilted her head, because… something about her sister seemed different?

“Hmm,” she said, focusing on Celestia’s pink ruffly frilly padded outfit with bows and booties and a tutu and swirls and spirals perfectly normal outfit. “Did you… get your mane styled?”

“Yes!” Celestia replied, then giggled. “That’s what happened! I’m definitely not being all sneaky!”

She wiggled her rump, giggling again.

“Well… good!” Luna said. “Right, uh, my turn to go out patrolling…”

Luna was soon waddle sloshing her own way around the vault, trying to not go too far with how slow and waddly her gait had become.

She... quickly became confused when she found a second vault somewhat nearby their super secret vault... did everyone know about the super secret vault?!

Huffing in annoyance, Luna waddled up to the vault and opened up, surprised to see... stacks of diapers. And in a big, poofy diaper of her own, Diaper Lord Ember sat on her pampered throne, grinning at Luna.

"Ah! A worthy servant to join my cause! I needed someone to take the diapers treasures from the super secret vault for me, and you will do nicely." Ember said, her own padding so poofy she could hardly move. "I'm, erm, a bit stuck..."

"Um... I'm supposed to guard the diapers treasure..." Luna said, though she was also supposed to steal them, so perhaps stealing them some more wouldn't be bad?

"That's why you're the perfect agent!" Ember said as a plushy and somehow familiar Night-Fury outfit bounded out of the diaper pile and pounced on Luna, jaw opening to nom her down in a single move that somehow ended up with her suited up properly wearing it the right way around, and then diapering her up in an extra thick dragon diaper as the eyes became swirly...

"Now Pamp-Fury, waddle along and get my diapers treasure!" Ember demanded, waving her rattle staff of entrancing light around.

"Yes, Diaper Lord..." Luna nodded, waddling back towards the vault, more ditzy and dizzy then ever…

Poking at the vault with her bootied hoof, Celestia wondered how exactly she was supposed to open it and get at the contents. It had all sounded very simple when she’d been ordered to open it, by…

...whoever it was, again? She couldn’t remember…

...but whoever it was, right now it was impossible to see how to open it. And she wanted to make sure she did what she was told.

Even if, right now, she was mostly feeling blushy.

Then she heard a sound, and looked around to see a dragon Luna waddling towards her.

“Are you trying to mess with that, uh, hoard?” Luna asked, suspiciously.

“No!” Celestia replied. “It’s not a hoard, I mean, I’m not trying to mess with it, I mean, it’s not something I’m trying to mess with! What do you mean, hoard?”

“Oh, um… good question?” Luna answered. “I wouldn’t say hoard because I’m totally not a dragon and I don’t obey Diaper Lord Ember!”

She blushed a bit. “Obey Diaper Lord Ember… um, t-that is, isn’t it your turn to go out on patrol and let me try to work out how to open this?”

“Right!” Celestia replied. “I, uh… yeah, I’ll go out on patrol! But you’d better not open this! Not while I’m not around! I mean, um…”

She blushed, squeezing her diaper with her hind legs. “I mean, you’d better not open this, because…”

The sentence trailed off, and the two sisters looked awkwardly at one another.

“Patrol!” Celestia said, eventually, and waddled off – leaving Luna to poke awkwardly at the vault with her plush-dragon-pawed hoof.

Celestia waddled her sissy, poofy and powdery butt in the only other direction left to patrol, hoping that she could sneak back later to open Guard the vault for Queen Crinklesalis, Queen Pampdance Soggfire.

At least, she thought she was supposed to be doing something like that, involving diapers treasures and secrets. It was hard to remember with her feeling so dizzy and ditzy...

"Hey dweeb!" A familiar voice said, belonging to none other then Gilda the Griffon Poofin representative. And this Poofin looked extra regal in her pink princess dress and frilly pampers, and the grumpy look on her face told her she didn't exactly like being royal. Or pretty.

Even though, in Celestia's totally unbiased opinion, she pulled off the look.

"Oh, are you joining the Sissy butts too?" Celestia asked, which earned a snort from Gilda, who was about to retort when they were both distracted by a faint "Clunk" from the sky as the full moon mooning them pressed against the glass, giving them an extra distracting show for a few minutes seconds.

"No! I'm supposed to be finding someone who can get into a dumb super secret vault," Gilda said as the wind in the dreamscape shifted, all the pink poofy powder from their pamps rolling over her and making it harder to remember why she was annoyed as she felt dizzy and ditzy. "Say... I'm sure you'll do!" Gilda perked up, flying up in the air a bit in a fit of silly inspiration before butt slamming down on Celestia with a big POMPF of thick diapers and silly filly power that had both "princesses" giggling.

"Now I just need to dress you up... where did I get..." Gilda frowned, the idea of playing dress-up seeming rather dorkish before her gaze was drawn to the moon swaying across the sky, leaving Celestia squirming under her pamps for a few minutes seconds before Gilda remembered what she was supposed to be doing, swiftly dressing up Celestia into the pink, powdered pink griffon suit.

Celestia saw the swirly, shimmery goggles activate on the griffon suit, and giggled as she saw even more swirls fill her vision, every flap of the wings of the griffon suit spreading silly filly powder and making them all giggly and squirmy and soggy~

“Now, you… hee,” Gilda giggled, then shook her head, and tried to get a more serious expression.

Then she looked embarrassed, before remembering what was supposed to be going on and fixing Celestia with a glare.

“So, listen up!” she said. “I’m a bigger Poofin than you, which means I’m in charge!”

Celestia looked back at her suit, which certainly seemed bigger, then Gilda shook her head.

“No, I mean, I’m in charge!” she insisted. “I’m a more important one than you! I’m the head Poofin, okay! And that means you do what I say!”

Celestia was still confused, with swirly patterns going across her vision, and Gilda glanced around at the mooning moon again before pouncing on something.

“Aha!” she said, and put on a giant mascot griffin-head several times bigger than her own head, which had a hole for her actual head to look through and which had a pair of already-swirly eyes.

“There!” Gilda declared. “See? I’m the head Poofin! That’s why I’ve got such a big head!”

Now Celestia couldn’t argue, and it was a lot less confusing.

“So go and open that vault!” Gilda added. “I’m sure there must be something silly valuable in there! That’s an order from the head Poofin!”

Celestia giggled, nodding. “Got it!”

“Good!” Gilda said. “Now, go back there quick! I want those diapers that treasure!”

Celestia sat down on her rump, making a big poof of powder, and tried to salute, but it took her three tries with how much they were both giggling.

As the hypnotized princess pony changeling sissybutt poofin left, Gilda reached up to feel the big plushy head she was wearing, and frowned.

“Why am I wearing this stupid thing, anyway?” she asked, reaching up to pull it off, but the swirly eyes glowed.

Her forelegs relaxed, dropping away from the big plushy head, and Gilda Frillda giggled.

“Oh, of course!” she said. “Because I’m the silliest of all the Poofins, as their Princess!”

Once Celestia got back to the vault, she found it was a little crowded. It seemed the secret about the vault was well and truly gone, or all the other princesses had gotten bored of waiting and had come over to see how their agents were doing, and now there was a three way argument between Embutt, Soggystream and Soggy Secrets over who's agent Luna actually was, with Soggfire trying to chime in and argue Luna was a Wonderbutt, since clearly they hadn't broken into the vault.

"She's clearly a Wonderbutt! My vault is still locked up as tight as her diapers!" Soggfire declared, huffing needily as the royals patted her bottom and kept layering cute diapers on her and Soggy Secret's butts, arguing over which patterns were better.

"I'm a Wonderbutt!" Luna agreed.

"No, she's a Shadowbutt! She's got on the Shadowbutt uniform and everything!" Soggy Secrets said as Embutt layered another diaper onto Soggfire's rump, only for Soggystream to add one to his rump too.

"I'm a Shadowbutt!" Luna agreed.

"No, She's Seapony! She can swim in water!" Soggystream said, patting Luna's extra soggy diapers. "And she's soggy like one too!"

"I'm a Seapony!" Luna agreed.

"No, she's a dragon looking for treasure! She loves shiny, swirly things, and she flies!" Embutt declared as Soggfire and Soggy Secrets were layered up again.

"I'm a dragon!" Luna agreed, and the argument kept going around and around in swirly, silly, soggy circles... and when Celestia waddled up, the debate began anew between Soggfire, Queen Crinklesalis, Queen Pampdance and Princess Frilla.

"Well, why don't we just open the vault and see what the Diapers secrets are?" Soggfire declared, getting tired of trying to have two arguments at the same time. "Even I can't get into the vault, so we'll have to put our heads together..."

Luckily, they would get a helping hand: they'd been so distracted they didn't notice the freshly changed, still swaying and shaking moon pamp coming down from the sky...

It sat on all of them and the vault with a massive POOOOMPFFF of powder and crinkles, filling the air with more pink silly filly powder as they were preeeeeesed into the vault door, forced to see the big, swirly pamp in their faces.

Nightwear did have the best diapers after all~

After smoooshing and squuuuuishing them for a bit to help press out those big girl thoughts, the vault door suddenly opened, spilling them all into the inside of the vault…

Author's Note

There seems to be a lot more in the way of Princesses here than before, including at least one honorary one.

Not a sign of things to come, I think.

Third Night - Dreams Within Dreams

“...bwuh,” Luna said, squirming a bit and looking up.

She felt kind of sleepy, like she’d been snoozing and just woke up, which was embarrassing when she was in kindergarten!

She… was in kindergarten, right? Luna couldn’t remember a lot of details about it for some reason, or about her dream, but when she looked around she saw that she was definitely in a kindergarten room. With her classmates, like her sister, and Frillda, and Pampdance and Crinklestalis, and Soggystream and Embutt…

“I hope you were sleeping in class,” the diaper-clad teacher said.

Luna blinked, then recognized her as swirly-eyed Twilight Sparkle wearing a Nightwear plush-suit that was giving all the orders Miss Nightwear.

“I-” Luna began, ready to automatically deny that she’d been asleep, then stopped. “Um… Miss Nightwear, don’t you mean you hope we weren’t sleeping in class?”

“But if you’re going to learn your lessons in kindergarten you need to get a lot of sleep,” Miss Nightwear replied, pointing at the posters on the walls.

Naps Are Good, Nightwear Is Best, Sleep Your Thoughts Away, Dream And Sink, Sink And Dream… they were all kinds of super true and believable slogans, and they all told her the same sort of thing.

Just looking at them made her feel dizzy, the tired feeling she’d had before turning into a sort of easy suggestibility, and Miss Nightwear nodded approvingly.

“And you’re all wearing your Nightwear Diapers, aren’t you?” she added, and Luna checked just to be sure.

She was wearing a nice, super-big Nightwear Diaper, just like everyone else.

“Umm… miss?” Celestia asked, waving her hoof. “What’s the lesson today? I, um… forgot?”

“I’m glad you asked,” Miss Nightwear replied.

“How come we’re here, anyway?” Frillda asked. “I remember, uh… something dorky and dweeby, and now, uh…?”

“Why are all of you in the same class as me?” Embutt said.

Miss Nightwear ignored them both, instead using a chalk to slooowly draw a yellow spiral on the board. Then she used another chalk to slooowly draw a white spiral, and a blue one, then speckle it with stars, until the whole class was paying attention and the whole board looked like a multicoloured spiral… that looked like a spiral galaxy, speckled with stars.

“Today’s lesson is about going deep,” Miss Nightwear told them.

"Going deep? Like in water? I know all about that already!" Soggystream said as she looked at the spiral. "Should I make a presentation?"

"We're doing deep into dreams, not water, silly," Miss Nightwear said, pointing to the well padded Luna. "Luna will be our volunteer for today! Come up here so I can help you show the class how to go deeper!"

"Me? Um... I guess I do know about dreams..." Luna nodded, though it took a minute for her to waddle her poofy, powdery butt up to the front of the class, closer and closer to the swirls that were even more distracting thanks to the swirls on all the other diaper butts in the room.

"Now Luna, tell me about dreams. This is your dream after all!" Miss Nightwear encouraged. "Specifically, how to we go deeper and deeper?"

Luna squirmed a bit as she tried to not giggle from all the silly filly powder around as she tried to concentrate.

"Well... the deeper you go, the more your dream thoughts mix with your real thoughts. But it's hard to get that deep in a dream since dreams get more fragmented the closer you get to real thoughts, so you can only really see real thoughts if someone is getting hypnotized," Luna said absolutely getting hypnotized as clearly none of them were getting hypnotized.

"So for educational purposes, Luna, since this is your dream, could you summon a bunch of swirls so we could see what going deeper looks like?" Miss Nightwear asked, shaking her swirly, spirally pamp as Luna and making her even more dizzy and ditzy.

"Um... sure..," Luna said, trying to concentrate and finding that, with all the swirls, she finally couldn't concentrate anymore... and with that, the walls of the school room slowly turned in to great, big purple swirly spirals that drew everyone's attention…

“Well?” the giant sphinx asked, plush paws thumping down on either side of her victim. “Are you willing to admit defeat?”

Gilda Daring Do shook her head, blushing, and tried to flare her wings, but they were caught in plush softness.

For failing so many riddles so far the sphinx’s magic had trapped her into a plushy soft sphinx suit over her plush Daring Do suit, and worse, because it was about her clearly being a silly kitten, it had a massive silly diaper!

“I’m not going to admit defeat,” Daring Do replied, legs pressing together. “I’ll – I’ll answer one of your riddles and get free!”

“Just one?” the sphinx asked. “It’s funny you think just one riddle will help you, kitten. You’re far too deep in my power.”

Daring Do’s head swam, the words making her feel confused and vague…

“But, well… if you’re ever going to get free, you need to answer some of my riddles,” the sphinx added. “So let’s try a very simple one. So deep it can’t resist, never wants me to desist. With defiance it tries to persist, until I insist. What is it?”

“I, umm…” Daring Do said, trying to focus. Trying to think.

“Of course…” the sphinx said, slyly. “You’ve lost so many riddles already, there’s only one thing you have left to give up, if you fail this one as well. Your free will.”

“It’s…” Daring Do said, mind blank. “Is it… a diaper?”

The sphinx chuckled. “Oh, no, but I can see what you’re thinking about. Kitten.”

“But-” Daring Do protested, but the Sphinx raised her paw and made a little circle with it.

“Obey,” she said, and everything got hazy…

Ember the dragon lord royal guard was standing at her post near the royal treasure vault, wearing her royal armor, when Nightwear wearing a plush costume of Spike waddled in, wearing his big, silly poofy pampers that was apparently a new royal fashion statement.

"Ember!" Spike declared. "I need you to go into the royal vault and put on a new uniform! I laid out everything already. I want to see if it would be fashionable for the guards to wear."

"At once my lord!" Ember said, clanking into the vault, watching the dial spin with dazzling swirls for a few minutes seconds before stepping inside... and immediately blushing.

"My lord... are you sure this is the right outfit? It seems rather... silly." Ember whined.

Spiked waved his shiny rattle Dragon Sceptre from side to side, making Ember feel all silly and dizzy.

"Of course it's silly! You're a silly guard for not following my orders! Now try on the uniform!" Spike said.

Ember now felt very silly after that scolding, so she took off her armor and put on her new uniform... a diaper, then a cute yellow nightdress that didn't even half cover her thick pampers, then booties that made her a bit silly and wobbly, a paci-gag that made her blush even more as she suckled on it, then the mittens....

"Good job Ember!" Spike said, and Ember felt like such a good royal guard!

"Now come here so I can look at the uniform." Spike said, and Ember waddled over, eyes following the staff as it went back and forward, back and forward.

"Guards don't think. Good Guards Obey." Spike said, and as Ember watched the Sceptre, everything went hazy...

"You're such wonderful tribute!" The mighty sea serpent said, her shimmery scales dazzling the princess in her coils no matter where the sea pony looked. "Now little Soggystream, you've had a poor showing in keeping those diapers dry, so I made this one extra special for our last little game! If you win, you get to go free! If you add another diaper to the pail, I get to keep a princess as your new mistress~"

SilverSoggystream huffed, trying to keep sloshy thoughts out of her head as the waves pounded the shore, wearing a cute pink one piece swimsuit with floaties and a thick diaper with pretty runes that was already spreading her legs apart.

"You'll see! I'm... I'm going to win this game fore sure!"

"Oh good! It's the same rules as last time. Do you remember the rules~?" The serpent asked, her scales shimmering as she slithered around SilverSoggystream's little tropical island, setting out three colored bottles, one pink, one white and one brown.

"Of course I do!" The princess said, her head too fuzzy to remember the rules, but she didn't want to look silly. Princesses never looked silly!

"Then begin!" The Serpent said, smirking as Soggystream waddled right up to the pink bottle and began to drink it. Just like she'd been told throughout their little games.

Soggystream gasped as her diaper suddenly grew warm. "B-but how?!" She said in confusion before looking up, the shimmering frills of the head of the serpent filling her vision.

"Obey," The serpent commanded, and everything became hazy...

Cadance the princess diaper maid was waddling her poofy tush up the stairs towards a ringing bell from Nightwear in a Blueblood costume Blueblood, entering the room and putting on her best diplomatic smile despite her slight potty dance: she hadn't had a chance to use the bathroom all day, and she was considering using her standard issue pampers to get through the day...

"Ah, there you are!" Blueblood said, turning his regal, royal pamp with all the shiny gem and coin prints on it, with a big crown printed on the butt. "Come closer and inspect my diaper prints, I must know if they're perfect!" he demanded, his rump swaying the shiny, sparkly prints back and forward...

Candance tried to focus on the prints, but the wiggling and swaying made it harder to tell if the patterns were perfect... and it made her own squirming get worse too...

"Um... can you stop moving? It's hard to see the patterns..." Candance said as she followed the patterns back and forward...

"Then come closer!" Blueblood demanded, so Candace waddled closer...

"Closer!" Blueblood demanded, so Candace waddled a mere few inches from Blueblood's rump, the swirly patterns filling her vision...

"Closer!" Blueblood demanded and Candace put her face in Blueblood's padding with a faint poompf and a puff of powder. His rump stopped moving... but she was doing a desperate potty dance now, and couldn't focus on the patterns!

"Silly diaper maid, no wonder you couldn't see the patterns. Wet." He commanded, and Candace felt her padding growing warm and heavy, filling her vision once more with nothing but pretty, pretty swirls.

"Obey", Blueblood said, and everything went hazy...

“All right, you’re doing so well!” Nightwear Fluttershy said.

Chrysalis blushed, her thick plushy Manticore suit moving around her and the diaper under the suit crinkling.

“This is humiliating,” she said.

“No,” Fluttershy told her, firmly. “Manticores don’t talk.”

Chrysalis folded her forelegs, looking away.

“Manna,” Fluttershy said. “Look at me?”

Chrysalis looked, and Fluttershy’s eyes were suddenly captivating and intense and swirling.

“Manticores don’t talk!” Fluttershy insisted. “Now, um, I’m sure you’re going to do well with this next trick… roll over!”

Chrysalis Manna the Manticore rolled over onto her back, and Fluttershy gave her a tickle belly rub.

“See?” Fluttershy asked, as Chrysalis Manna giggled and squirmed despite her best efforts not to. “See how much better you can be when you’re a good pet?”

Good pet, good pet, good pet. The words echoed in Manna’s ears, and she blushed.

The idea of being a good pet was so insistently, powerfully attractive, pulsing in the front of her mind and filling her thoughts, and when Fluttershy stopped Manna rolled back over onto her front and wagged her plushy tail.

“Now, sit!” Fluttershy said, and Manna sat on her crinkly, plushy rump. “Good! And…”

Manna waited for the next order, the urge to be a good pet impossible to ignore.

“Obey,” Fluttershy told her.

And everything went hazy…

“Ready for your next lesson, Twilight?” Nightwear in a Celestia suit Celestia asked. “Remember, if you get this just right, you can get into Magic Kindergarten!”

“I, but-” Twilight began, confused, looking around the schoolroom. “Isn’t… I thought I didn’t want to go back to Magic Kindergarten!”

“Oh, but you do,” Celestia told her. “After all, you need to go to Magic Kindergarten to learn Magic, don’t you? That’s why it’s called that.”

Twilight blushed. “I don’t know if that makes sense, Princess?” she said.

“But you trust me, don’t you, Twilight?” Celestia replied. “After all, I am your teacher. And are you a good student?”

“I’m… a good student,” Twilight answered, blushing.

“That’s good,” Celestia said. “So here’s your first reminder of what good students do…”

She pressed on her own diaper, making a crinkly noise. “What’s this?”

“A… diaper, Princess?” Twilight replied.

“Good,” Celestia smiled. “I’m so glad you know that. And here’s your first instruction, so you can qualify for Magic Kindergarten. Wet.”

Twilight blushed again, then did her very best to wet. It took some concentration, then her diaper sagged a little.

“Hmm,” Celestia frowned. “I think you’re having to work too hard at this, Twilight. But that’s all right, I know just the lesson to help with that.”

Her horn glowed, and she made a little glowing, sparkly star appear in front of Twilight. “It’s a simple relaxation technique. This is your thoughts, you see.”

“My thoughts,” Twilight repeated.

“Your thoughts,” Celestia said. “Focus on it, pay attention to them. Watch as they get dimmer, and dimmer… and dimmer… and let your thoughts get dimmer, and dimmer… and dimmer…”

The star got dimmer and dimmer, with the only light in the schoolroom being the sparkly stars and the glowing patterns on Celestia’s diaper, and her voice lowered to a whisper.

“Without any thoughts, you don’t have anything to get in the way,” she said. “You just…”

The star winked out.

“Obey.”

And everything went hazy...

“Ready for this, trainee?” NightwearSoarin’ asked, looking at Celestia Rainbow Dash. “You’ve got to know how to do every part of being a Wonderbutt to be a Wonderbutt, you know!”

“Yeah, I’m ready!” Dash agreed, nodding at the plush-suit of her new superior. “Though, uh… I know about how everypony who becomes a Wonderbutt has to know all the bits of being a butt, but I guess I expected there to be less of… this?”

She waved vaguely around at the factory equipment and supplies.

“It’s to make sure you’re properly humble, of course!” Soarin’ replied. “And that means being willing to follow orders, of course. If we tell you to do something, we want to be confident that you’ll do it without being too distracted by how dull you think it is. Following orders without being distracted is the key here.”

“I get it!” Dash replied, her plush suit and diaper crinkling. “So, what do I do, then?”

“Well, you’re working with cloud fluff!” Soarin’ explained, pointing to a big big biiig bag of the stuff next to her. “And, first off, you need to stuff that diaper on the table!”

“Uh… right,” Dash said, remembering that she had to follow orders without being distracted, and began stuffing the diaper.

It was repetitive, routine, and Dash kept going. Kept stuffing away, filling one diaper with cloud fluff, and then another, and then another… then the things she was filling changed, and she looked up. “Uh-”

“You’re here to show you can follow orders without question,” Soarin’ told her, smirking. “Unless you don’t think you can hack it?”

“I can hack it!” Celestia Dash replied, blushing, and began stuffing the plush in front of her.

It was a Princess Twilight Sparkle plush, and she stuffed it full of cloud stuff, especially the head, making it nice and airy and puffy, and stuffing the diaper of the plush too until she’d finished stuffing the Princess Twilight Sparkle Damplight Soggle plush.

Then there was a plush of Silverstream, and she stuffed until she was done with the Silverstream Soggystream plush.

Then came Cadance Pampdance, and Gilda Frillda, and Ember Embutt, and Chrysalis Crinklesalis, and Luna Nightwear’s Special Daughter, but as she began to do the Celestia Celestinkle plush she blushed.

“Uh,” she began. “I’m feeling kind of, uh… fuzzy?”

“Of course you are, that’s fuzzy cloud material,” Soarin’ replied. “Better hurry or you won’t be cool enough to join the Wonderbutts!”

“Right!” Celestia Dash replied, filling herself the plush up with floaty soft clouds that left no room for thoughts, and felt lighter and more giggly as she did.

“Very good,” Soarin’ said, by the time she’d puffed up the Celestinkle plush to the point it was as big as she was. “Now, just put the diaper on it!”

There was a diaper there on the table, a Nightwear diaper of course, one of the ones she’d stuffed earlier, and Celestia DashCelestinkle put a Nightwear diaper around her own the plush rump rump.

“That’s very good,” Soarin’ said. “I’m glad you’ve learned to sink and obey.”

Celestinkle sank and obeyed...

“You understand, don’t you?” Nightwear Moon asked.

Luna blushed. “I don’t know what you mean?”

“Oh, but you do,” Nightwear Moon replied. “You’re wearing my symbol on your diaper. You know what that means.”

Luna looked back, and saw that she was wearing a Nightwear-diaper. It covered up her cutie marks, and she squirmed in embarrassment.

“That’s… it doesn’t have to-” she began, but Nightwear tapped a plushy hoof on the ground.

“Understand what it means, and sink deeper,” she said, and Luna wobbled as everything felt fuzzy around her.

She… did understand what it meant. It was a mark of the control Nightwear had over her, and because it was there so insistently in her dreams it meant that that control was strong.

“You’ve been enjoying what’s happening, haven’t you?” Nightwear asked, with a smirk. “You know what that means.”

“I-” Luna began, then stopped, trying to focus.

Did she like it because Nightwear had changed her preferences, or because she’d always wanted this to begin with? Was she so thoroughly corrupted, or was this something she’d always intended on happening to begin with?

“Understand it, and sink deeper,” Nightwear told her, and Luna felt the truth pressing in on her.

They were both true. One of them was true. Whichever one was more embarrassing, it was true, and it had to be at least one of them. And it could be both of them, making it harder and harder for her to resist Nightwear.

“Not harder,” Nightwear said, in a whisper. “Impossible. You can’t resist me. Understand that, and wet.”

Luna blushed, utterly unable to resist the command through the web of suggestions and commands and dream memories in her mind.

It was like every time she recognized part of it, it only made it stronger… but she knew that not recognizing the influence would make it stronger as well. It was a contradiction, but both things could be true at once, and Luna’s head fuzzed with the insistent reality of Nightwear’s total dominance.

“Now…” Nightwear added, getting Luna’s attention. “You know all of this, and part of you will never forget it. Never stop knowing.”

The Nightwear diaper was growing over Luna, swelling as her submission became more and more insistent, covering her over with a plushy-suit version of her younger self… and one that was, itself, wearing a Nightwear diaper.

A symbolic representation, and one that Luna was too fuzzy – too embarrassed – to protest.

“But apart from that… forget,” Nightwear told her. “Just remember that you have to obey me… and that you’re my special daughter. Obey. Obey.”

Luna sat back on her diaper, sinking deep into a fuzzy, hazy trance of total blissful obedience…

Epilogue – Waking Dreams

...Celestia yawned, shifting in her bed, then kicked the covers off and yawned again.

“Mrfphle,” she said, regally, then took her pacifier out of her muzzle and let it dangle on her necklace.

“What should I do this morning?” she asked.

Her horn lit up, and she moved the Nightwear plush sitting on her bedside table up and down a little.

“You should show me your diaper,” she said, in a different voice, then blushed. “Okay…”

Standing up and turning away from the bedside table, Celestia undid the flaps of her onesie, and her soggy Nightwear-diaper stuck out a bit.

“Wow, you’re soggy! That’s a good princess… go and get changed,” she said, making the Nightwear plush move again, and nodded before picking up the plush, putting it on her back and waddling for the door. “Yes, Nightwear…”

Luna had got up just before her, but that wasn’t a problem, because they had a big enough changing room in their house to change both of them at once… and, of course, easily enough Nightwear diapers to supply all the changes they could ever need.

It was funny how that worked out, but Celestia didn’t notice anything strange about the idea. She simply didn’t see anything unusual about having an infinite supply of diapers, because there was nothing strange about it.

Once they were freshly changed, into puffy new diapers (one of the best kinds of diapers, along with the other kinds of diapers), both sisters took their seats at the breakfast table and began eating tasty sugary cereal.

Luna wiggled her diaper in her seat, enjoying the feeling of it and blushing a bit, then looked up at her sister.

“Did we have a plan for today?” she asked. “I don’t recall precisely.”

“Of course we have a plan,” Celestia replied. “You remember how you enjoyed our game of golf last month?”

“You don’t need to remind me,” Luna blushed, remembering how she’d grasped the idea of hitting the ball very hard a lot sooner than she’d grasped the idea of aiming.

“Well, I’ve invited some of the other Princesses out to a game of golf,” Celestia reminded her. “Gilda, Ember and Chrysalis will be there… though I think we’re going to need to loan most of them golf clubs.”

Luna frowned. “I hope at least one of them isn’t obviously much better than me.”

“That’s for us to find out, isn’t it?” Celestia asked, winking, then took another mouthful of Sugar Moons.

"Can you get them the clubs?" Luna asked her sister as they finished breakfast. "I've got to see what Nightwear wants me to do today while you do that." She giggled bashfully.

"Of course!" Celestia said. "I'll get some cupcakes while I'm out too!" she added, always having a sweet tooth.

"Good idea! Extra sweetness can't be bad for Chrysalis, it's great she's turned over a new leaf lately," Luna beamed.

"I'll be sure to get plenty of sweets and clubs!" Celestia said as she waddled out to get the clubs and sweets, diapers crinkling the whole way.

Heading to her own room, Luna waddled up to her Nightwear plush. "What should I do today? We're playing golf!" She said.

"Make sure to bring lots to drink!" Luna said in a different voice, making the plush move. "And every time you get a ball in the hole, you need to have a victory wet."

Luna blushed, giggling. "Okay! Anything else?" She asked the plush before responding to herself in a different voice, "Of course silly! You need to wear your princess plush suit!"

"Sure thing, Nightwear!" Luna beamed, waddling to her closet to get out the Luna Plush suit with a big, bulky Nightwear diaper on it, and wiggled her way into it. She then did some chores to clean the house and sort the poofy diapers into nice neat piles at the changing table, just in time for Celestia to arrive, wearing her own Celestia plush suit with thick Nightwear diaper and carrying the extra golf clubs and cupcake treats.

"Perfect timing! I just got ready." Luna beamed, both princesses waddling towards the golf course.

Nopony even gave them a second glance. After all, it was normal for princesses to waddle around in puffy pampers and plushy princess suits.

And, as far as anyone was concerned, it always had been...

And there we go! It's been a while since I've posted something on here, but hopefully this has been a fun little read.

Prologue - Completely Sensible Decision

In the small hours of the night, a pony slept.

That didn’t actually stop her from doing something else with her time, something more useful, because the pony was Princess (emeritus) Luna. She had spent a thousand years on the moon after her indignation over not having enough of a role in Equestria’s government had boiled over… then, not long afterwards, she’d discovered that actually having a say was even worse and she’d decided not to have a role at all thank you very much.

But she still kept her powers over the dream realm, and that was why she was doing something useful with her time despite how late at night it was.

“Hmm,” Luna frowned, considering, then focused her powers, and an alicorn statue appeared in front of her. Made of onyx and speckled with faint stars, it looked a lot like the Tantabus that she had created in the past, but Luna wasn’t going to make that mistake again.

Instead of creating something to torture and punish her, she wanted it for something else. A simpler purpose.

The Tantabus had been to make sure she could never forget her corruption as Nightmare Moon, by reminding her of them every night through nightmares. This was… not going to be for that.

It was made up of her own memories of what she had done as Nightmare Moon, yes, but it was just going to be… there. In her dreams, as a memorial.

“I think that should do,” she said, trotting around the statue, then corrected herself by giving it the regalia she’d worn as Nightmare Moon.

Another tweak, and she added a flowing mane of stars.

Then she changed it a bit more, adjusting the eyes.

“...no,” she said, eventually. “If I keep changing it, I’ll never stop.”

Touching her horn to the statue’s horn, she pushed into it her memories of Nightmare Moon, then sealed it against any further tampering she might do in order to rid herself of the temptation.

Morning was coming, and Luna slipped away through the veil of thought to wake up along with her sister – to enjoy the retirement that Celestia had waited over a thousand years to enjoy.

And, in the dreamscape, the Nightmare statue smirked.

I’m sure that won’t have any negative consequences.
