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…
