Dream Cycle - Celly and Lulu

Celly and Lulu waddled back and forth, each trying to maintain their balance as the bulk of their yovidiaperhpones disappeared, turning into colorful vests for their school uniforms. Celly was the first to recover, looking down at Lulu's deep blue vest. “Oooh, Lulu, your vest is so pretty! Pinkie was right, night is the best!” She grinned, admiring her sister's uniform. Lulu shook her head, coming back to her senses.

“Oh um... I suppose it is. I still think yours looks better. It's so bright and colorful,” she replied. Celly shrugged, pulling out their schedule.

“Well, it looks like cooking is next. Maybe you can spill some frosting on your vest and make it brighter.” She teased, heading back down the hall. Lulu followed, both of them soon making their way into their next class. Rather than a standard classroom, this one was lined with miniature ovens and refrigerators. Standing in front of one of the ovens was another puffy pony, her orange rump shaking left and right as she pulled out a piping hot apple pie.

“Howdy girls! You're just in time for our sample for today! Ah've got just the thing for a couple hungry fillies!”

It was when the sweet aroma of the pie hit their noses that both ponies realized just how hungry they were, eagerly stepping up to take a slice.

“Well, now, looks like you like that there apple pie,” the puffy pony said, her smouldering red-and-yellow slit eyes watching with amusement as Celly and Lulu took their slices of pie – slathered with cream, of course – and sat down on the chairs with a crinkle to begin digging into them. “Name's Applejack, though if you feel like bein' fancy you all can call me Miss Applejack. I ain't gonna insist though.”

“This is… mmmf, wow!” Celly said, licking her lips. “I thought cake was better, but this pie is just… amazing!”

“Cake, hey?” Applejack asked, resting one hoof on the nearest counter and crinkling idly. “Well, ah might not mean t'boast, but there's some mighty fine cakes you can make here in home applenomics… just like y'all could fritter away the time making some right bewitching fritters, or any other kind of apple product that comes t'mind. Don't that sound like it beat all?”

“It… does sound really tasty,” Lulu agreed. “But… are they all apple?”

“Well, now, seems to me like that's a challenge,” Applejack smirked. “And if you girls want to have more after that sample, seems to me it's time that y'all get to cooking!”

Lulu looked down with disappointment to see that the pie was all gone, and licked her lips – quite ready to have another entire pie, let alone a slice.

“Don't worry none,” Applejack added. “If y'all do your work well, ah'll see about letting you have another slice while you work.”

Celly let out a soft burp as she finished her pie, patting her belly happily. “Ooh, if I could make something even half that delicious...!” She sat up straighter in her chair, watching Applejack attentively. The pony chuckled, clearing off the counter that the pie tin was on and lifting up two thick recipe books.

“Well then, we should get started 'fore you all think about gobblin' me up!” She handed the cookbooks to the ponies before she began to retrieve several ingredients from the cupboards. “We'll start with a visual demonstration, so y'all get an idea of how to bake 'fore we throw you in the deep end.” She dropped the ingredients onto the counter, picking up her own copy of the book. “We'll start with some baked apple, and make sure you pay very close attention!” She urged.

Lulu flipped to the appropriate recipe, looking very closely. The recipe seemed simple enough to start with. Just some cored apples, peanut butter, chocolate chips, and cinnamon for flavoring. Each step was accompanied by a photo to show how one should cook the apples, filling the cores with the peanut butter, chocolate, cinnamon mix, and how to serve them as well.

As Lulu read along, she realized she hadn't really been listening to Applejack's explanation, so she quickly looked up to see her holding a tray of neatly cut apples, offering out more samples. Celly and Lulu took some, finding them to be just as good as the pie they had eaten. “I hope you got all that, it's your turn to make some sweets for each other to try!”

Celly huffed slightly, then sighed and shook her head.

“I suppose I can live with that if Lulu is making sweets for me… even if I'm going to be making treats for Lulu,” she teased.

“It seems fair to me,” Lulu agreed with a chuckle. “Now… what are we going to be doing, Miss Applejack?”

The plushy farm-pony turned over a few pages in her cookbook. “We're making these here apple cinnamon pastries, right enough – you'll enjoy 'em good!”

Celly turned to the same page in her book, and blinked a few times – the picture was nice, and looked very tasty, but it was a little hard to focus on the words.

“What you got to do is to take some cinnamon and sugar, and mix them together,” Applejack went on, demonstrating with a bowl. “Around and around, mixing in the cinnamon and the sugar… isn't that right, sugar? Mixing in sweetness by going around and around… then adding in the apples, mixing them around and around in the sugar too… don't that sound so tasty?”

“It does sound tasty, yeah...” Lulu said, copying Applejack's movements. Around and around…

“Then you take the pastry, and you fold the apples into them,” Applejack explained. “Trapping all that sweetness in, so when it goes in the oven it'll melt a little and turn into lovely apple filling...”

Celly yawned, feeling more than a bit dizzy.

“And they're done!” Applejack said suddenly, taking the tray out of the oven.

Celly blinked.

Had they really been in here that long?

That question was washed away by the sweet taste of the first pastry, and it didn't really come back.

“Alright, now get to your stations. You can't stuff yourselves all day. At least not until you've made them yourselves.” Applejack teased. Lulu and Celly stepped out of their chairs, each one reluctant to leave behind the sweets and taking a few with them.

They waddled over to their cooking stations, opening their books to the appropriate page. Celly started by imitating what Applejack had done by mixing together the cinnamon and sugar. While doing so she was looking through the rest of the recipe, which was now telling her how to mix together the yeast to make the dough.

Dough?

Celly paused. She didn't remember seeing Applejack making dough for these pastries, she thought that was already done for them. She dug around in the cupboard, looking for the yeast.

Meanwhile Lulu was already attempting to prove her dough. She was kneading and squishing it about. She poured the cinnamon and sugar into the mix, and watched as everything swirled together. She giggled a little as she enjoyed the plush doughy texture in her hooves. It squished and smushed around, and she could feel like she could just flop down into a bit mass of warm puffy dough.

Celly switched on her oven, starting to heat it up and swishing her padded rump in front of it to keep her padding toasty.

The cooking process passed in a kind of slightly dizzy blur. The bits which each student alicorn found boring passed quickly, almost without their needing to pay attention, but the bits which sounded nice or tasty or pleasant stretched out for Celly to wiggle and fluff her rump or mix dough or for Lulu to swirl her ingredients and fold her dough together.

“That's right,” Applejack said, crinkling a little herself. “You just get you into a rhythm, right enough, and the cooking goes right by… just let it take over, no need t' think...”

“Mmhmm...” Celly agreed absently, nodding as she baked and baking as she nodded, and time seemed to swim by as ingredients became dough became pastry.

“Yep,” Applejack went on. “The oven's makin' the room so warm, so easy to get drowsy… warm an' all… like a lovely summer day...”

Lulu pulled the tray out of the oven, tasting one of the apple treats and gasping at how hot and tasty it was, and sat back with a flumph on her padded rump.

“But you gotta test out the drink, too,” Applejack reminded them. “What kind of drink would go best with apple pastries like this?”

“Well, uh...” Celly began. “I guess… hot chocolate? Or spicy apple mead?”

Applejack snickered poking Celly and making her rock back on her rump a little. “Cider, silly! Everypony loves apple cider, after all.” Applejack produced two bottles of cider, handing one to each of the princesses. Celly popped the bottle into her mouth, letting out a sigh as she began to drink the cider down. She leaned backwards, the cider warming her up just as much as the oven warmed her rear. The bottle seemed to hold much more cider than Lulu expected, but that thought was quickly washed away with another drink. She rocked back and forth, leaning further and further back with every drink. Applejack waddled over to her, leaning down to see some dough that had splotched onto her padding. She gave it a poke, smirking a bit.

“Oh dear, Lulu, I think your dough's still a bit under done! They'll need to be put back in the oven!” She bounced her rump into Lulu, knocking her into the oven. Lulu squeaked as she was enveloped in warmth. She let out a sigh, finding it only pleasantly warm.

She closed her eyes, wiggling her rump as her padding began to slowly rise...

Celly was still gobbling up apple treats and drinking cider, patting her gut as it slowly filled with sweets. Her belly stretched outwards, sloshing as it grew bigger and bigger.

Cozy warmth and happy eating both filled the next several minutes, or hours… neither Celly nor Lulu could have told any-pony how long their class with Applejack went on for.

The plushily plump earth pony happily told them about how good it felt to eat food you'd prepared for yourself, and how much easier it was to relax with your hunger sated on a warm summer day, and how good the sun was, and how much better days were than nights… it all faded into a warm, cozy blur and drifted past…

“...and you'll find your lunchboxes full of extra treats from class,” Applejack said, her words drifting out of what seemed like nowhere. “So you'd better get goin' to your next lesson, or y'all are gonna be late!”

“Late?” Celly replied, blinking. “I… r-right, yeah!”

She glanced over at Lulu, whose padding was still puffed up from her time being cozily warmed in the oven. “But… wait, shouldn't there be lunch at some point?”

“After all those pastries you still want lunch?” Lulu giggled.

“I – well, um…” Celly blushed. “Never mind...”

“That's right,” Applejack agreed. “Y'all next lesson is Fluttershy's class about animals. Don't forget, the sun's better!”

“The sun's better,” they both mumbled, eyes blurred for a moment as the odd greeting sounded just right to repeat.

The two waddled off to their next class, no longer needing to check their schedule or the map of the school to find where they were going. Instead they just wandered through the halls, ever turn seeming to bring them to the right place, even if they weren't entirely sure where they were meant to be going.

They soon came to a classroom with several large tanks set up within it. Most were filled with small critters, one had a snake coiling around a stick, another with a rabbit munching on some carrots, but a couple were filled with water, fish swimming around within, shrimp cleaning the tank walls, and a few octopuses hiding among the rocks.

Lulu stared up at a bird on a swing which cocked its head to stare right back down at her. “Hello! You're just in time for class!” A quiet voice could be heard from the front of the room. A yellow pegasus was standing by a desk, although she didn't seem to command quite as much attention as the others had. She gave a slightly nervous smile as she trotted up to Lulu. “I see you like Cerulean here. Do you know what kind of bird he is?” She asked.

Lulu looked back up, scratching her head as she tried to think of the name. It seemed like it should be obvious... it was a bird... and blue... but…

“I… I'm not sure,” she admitted, blushing a little.

“That's all right,” the pegasus told her, blinking her cool, slitted blue-green eyes. “If it helps, I'm fluttery, and a bit shy, so I'm Fluttershy. And he's blue, and a bird, so...”

“...oh!” Lulu realized. “A bird-blue!”

“That's close enough,” Fluttershy told her. “A bluebird, but you were very close. And, as a reward, you get this!”

She passed Lulu a piece of bluish cloth, the colour of the late afternoon sky, and Lulu examined it. It looked sort of like a wing, but very plushy and thick.

“I… well, thank you?” she said. “What is it?”

“It's your reward for answering a bluebird question,” Fluttershy told her. “You put it on your wing.”

As Lulu began to do so, still a little confused but unwilling to question it, Fluttershy turned to Celly. “And what about this one?”

Celly examined the tank Fluttershy had indicated, and brightened. “Oh! I do know that, that's a lobster.”

“You're right, but that's not the question,” Fluttershy said. “If that's alright, I mean?”

“Of course,” Celly assured her. “You… are the teacher?”

“I don't want to be a bother,” Fluttershy said quietly. “But… well… I wanted to ask if you knew what was different about the claws a lobster has.”

“What's different about them...” Celly repeated, and looked at the lobster in the tank. She crouched close, her butt wiggling in the air as she tried to get a good look, then realized. “Oh! They have two different claws, they don't have the same one twice!”

“That's exactly right,” Fluttershy praised her. “So you get a lobster claw for your leg.”

She passed Celly the plushy costume piece, and returned her attention to Lulu.

“How about him?” Fluttershy asked Lulu, pointing to the noodly fuzzball beside the rabbit. Lulu pondered the peculiar animal in front of her.

“I think it's a ferret.” Lulu said, watching as it spun around in place excitedly.

“Very good!” Fluttershy praised Lulu, giving her a push paw to slip over one of her legs, which she promptly did. “Can you tell me where they like to live? For extra credit, that is. I, um, don't mean you won't get your normal credit...”

Lulu watched as the critter slipped into a small tube, poking its head out to look back at her.

“Uh, the woods? Where they can play in logs and stuff?” Lulu asked. Fluttershy smiled warmly, patting Lulu's flanks. With a puff, her padding fwoomped up slightly, swallowing up the base of the sleeve of Lulu's ferret stocking.

Celly was playfully waving a hoof around in the snake terrarium, the small animal's tongue flicking out occasionally to lick her. She giggled, watching as it slithered up around her hoof.

“Oh, careful, Celly!” Fluttershy said, hurrying over. “A cottonmouth snake's awfully dangerous! Don't you know that? Oh, well, I guess you wouldn't, that's the whole point of the class...” Fluttershy let out a nervous giggle.

“What's so dangerous about them?” Celly asked.

“Well, if they bite you, you'll feel all numb and cottony, and you'll turn big and plushie too!”

“Oh!” Celly said. “So… I should be careful?”

“That's right!” Fluttershy agreed. “You should watch out, because if you make a mistake and startle it...”

Celly gasped slightly.

“Oh, dear...” Fluttershy simpered – rolling her eyes, though neither Celly nor Lulu noticed. “You've been bitten! Now you're going to get all big and plushie, oh dear...”

“It doesn't feel all that bad,” Celly said, examining her leg as the snake slithered back down it. “Well, I guess it does feel kind of numb?”

“That's because of the bite,” Fluttershy explained. “Um… you're going to just feel all numb, but you'll start to swell up… oh no, there it goes...”

Celly began to get larger and plusher, the lobster-arm she'd already earned growing with her, and her diaper seemed to flow outwards – covering her in plushy material at speed, leaving her looking snug and warm and huggable.

“I, um...” she protested. “This is… uhh...”

As she tried to put together the words for what was happening, Lulu was making friends with a raccoon – answering Fluttershy's question about how raccoons had good manners, and earning a nice plushy pair of raccoon paws for her forelegs. Then she noticed what was happening with her sister, and blushed. “Celly! What happened?”

“W-well, I… think we should still do the lesson,” Fluttershy told them both. “Perhaps Celly would like to do a question about a bird? I've got a nice bat called Shade, but that seems more like one for Lulu...”

Celly flopped onto her thicker rump, a cloud of foal powder puffing into the air as she did. “I guess I can talk about some... birbs...” Celly shook her head, the plush fuzzy feeling spreading over it as she became a little dizzy. Fluttershy smiled, drawing the thickening filly's attention to a different cage where a brightly colored bird bobbed up and down, peering down at them. It puffed out its chest, flashing its wings and tail at Celly.

“Can you tell me what this bird is?” Fluttershy asked as the bird continued its fancy display.

“Oh, I know this! It's a bird of paradise!” Celly said, eagerly getting back to her hooves. Despite her bloated form, she attempted to replicate the bird's movements. She giggled, shaking her butt around just like the bird did, puffing her chest out and bouncing in place.

Fluttershy giggled, handing over a bright tail to slip over Celly's so that she could better frame her bottom for the bird.

As Celly continued her mating display, Lulu bounced over, polishing an apple she'd swiped off of Fluttershy's desk with her raccoon paw. “Who's Shade?”

“Oh, he's Shade!” Fluttershy said. “He's a vampire bat! Oh, wait, I was supposed to let you guess... oh well, you know what vampires do, right?”

Lulu looked up to see the bat hanging from the top of a cage, flashing fangs at her.

“Well, they… I think they suck something?” Lulu asked.

“That's right, they suck things,” Fluttershy agreed. “And it's good you have that apple with you, that'll be a great help!”

“It will?” Lulu blinked. “Oh! So they suck fruit, I see!”

“No, um… n-not exactly,” Fluttershy corrected. “Um… if you want to see, then Shade can demonstrate...”

She opened the cage door, holding out her soft-looking forehoof, and Shade came fluttering down to rest on it. He showed off his fangs, and Fluttershy petted him gently on the top of the head.

“Who's a cute little chiropteran?” she asked. “That's right, it's you!”

Shade preened, then took off and nommed on Lulu's ear.

“Ah!” Lulu said, surprised, and nearly dropped the apple. “Hey, what was that for?”

“Well, it's what they do,” Fluttershy explained, as Celly continued to shake her butt in the background with the colourful feathers waving back and forth. “They drain fruit from ponies, and then the ponies drain fruit from fruit.”

Lulu blinked, wobbling to the side a little, then bit into the apple and sucked all the succulent juice out of it.

“There you go, see?” Fluttershy giggled, giving her a plushy bat-wing to go with her bluebird-wing. “Isn't nature wonderful?”

Lulu couldn't help but agree, seeing nothing wrong with such a silly intermediate step as her cheeks filled with apple juice. She gulped it down, humming happily.

With both ponies distracted, it wasn't hard for Fluttershy to continue rattling off questions for the two. Celly correctly identified a hare (though that was certainly one of the easier questions), while Lulu knew about the intricate relationships between manticores and dragons, and earned herself a large claw as well. Celly was sent running around the room in panic when Lulu slipped a millipede down her padding, only for Celly to retaliate by spraying Lulu's rump with a squid's ink.

Soon the ponies were an amalgamation of animals to put Discord to shame, Fluttershy praising them with every new animal part they earned. “I think you've truly gained a new appreciation for animals!”

Once they were fully re-dressed, Fluttershy gave them both a hug and sent them on their way to their fashion lessons – but not before telling them both to love the night, which made both Celly and Lulu smile at the very kind greeting.

“I learned a lot!” Lulu announced, as they waddled through the corridors of the school and she flapped her mismatched pair of suit-wings. “There's so much about animals that's fascinating, isn't there?”

“You're right, Lulu,” Celly agreed, her tail bouncing a little as she walked. “But, hmm… I wonder who's going to give the fashion lesson?”

“It's going to be Rarity, isn't it?” Lulu said. “We've seen her already, she got our uniforms sorted out… though I suppose we're not really wearing them very visibly now. I hope she won't be upset.”

“I'm sure she won't mind,” Celly decided. “Though I wonder what the lesson's going to be about… and where the lesson is, actually...”

She frowned, losing focus a bit, then turned the corner. Left, right, and she was standing in front of the door to the room.

“Oh!” Lulu said, impressed. “Good work, Celly!”

She pushed the door open.

“Ah, good afternoon, darlings!” Rarity said, adjusting a pair of novelty glasses balanced in front of her slit orange eyes. “I'm glad you're on time to your fashion lesson!”

Celly and Lulu stepped into the classroom, looking at the bundles of fabric on display in one corner, while several dresses hung in another. As they entered however, Rarity's look of excitement turned to one of modest disgust. “Ah, and it's a good thing you've arrived too. We'll have to get you out of those ghastly night attire and into something more fitting for the day.

Lulu looked down at her suit, tugging on one of the legs a little. “What's wrong with them? They're warm and comfy, aren't they?” She said.

Rarity nodded, floating a measuring tape over as her horn glowed, “Well, yes, comfortable is always a good quality to have, but you want to be in something that properly shows off your padding too, don't you?”

Celly nodded, supposing that made sense. There was the sound of the suits unzipping, and Celly and Lulu found them slipping easily off of the other before being stuffed into respective cubby holes as Rarity walked around them. “And you don't even have your old uniforms on under them? Goodness, it's a very good thing you've got fashion lessons! Don't you worry, you'll be making some lovely outfits for yourselves soon enough!”

Rarity handed them each a roll of tape before trotting back to the front of the room. “First things first, you'll have to take your measurements to make sure your dresses will fit! You don't have to be perfect, if something is just a bit too small we can always add some puff to get it to the right size, and if it's too big, that will work just as well too! Puffiness does tend to solve a lot of problems like that.”

“Are you sure we'll have enough time in the lesson to do that?” Lulu asked, a bit uncertainly. “That sounds like quite a lot to do in one lesson...”

“Of course you will!” Rarity replied firmly. “Who's the teacher here?”

“Y-you, Miss Rarity,” Lulu said, abashed. “Sorry...”

“Well, it's not a big problem,” Rarity told her, relenting a little. “Now, since it's harder to take your own measurements, you'll be measuring one another.”

“Okay, um...” Celly began, using her horn to hold out the tape. “So… what bits do we measure?”

“Anything you think seems important,” Rarity waved her hoof airily. “Just go ahead and do it, see how it works out!”

Thus advised, Celly began by measuring the length of Lulu's horn. Then she measured how long each of Lulu's legs were, one at a time, and Lulu started trying to help by measuring the same places on Celly at the same time.

Things quickly got confusing, especially when Rarity pointed out that they'd need to model diapers of the right thickness and both sisters understood that to mean much thicker than the ones they were wearing right now, and after about ten minutes Celly was hopelessly tangled up in measuring tape and her only solace was that Lulu was also tangled up in measuring tape underneath her.

“This has not worked,” Lulu mumbled.

“But it seems as though you have quite enough measurements!” Rarity said brightly.

Rarity's horn glowed and encompassed both fillies before suddenly yanking the measure tape out. The two spun around and around as the tape untangled itself, Celly rolling off of Lulu before the two were left wobbling in place as Rarity rolled up the tapes neatly and placed them back into her desk drawer. “Now that you've got your measurements, the next step is picking out the fabric you want. There's lots of choices, each with lovely little perks. There's smooth, flowing silk, soft, cushy cotton, or if you're feeling brave, squeaky vinyl gives a marvelous shine to anything that it lines.”

Spools upon spools of fabric floated and unraveled themselves in front of Celly and Lulu, each one having difficulty deciding. “And that's just one fabric! The best kind of clothes mix and match a couple for a multitude of wonderful comfortable styles! And we haven't even gotten to patterns yet either! Stripes, polka dots, plaid, checkerboard, stars, diamonds, anything you could possibly wish for!”

Celly's eyes spun as she tried to keep track of all the fabrics, Lulu not faring much better as she raised a hoof to point something out in the swirl of color in front of her, only for it to be lost in the blur.

Eventually Lulu gave up trying to make sense of it, hoping that whatever she chose would be good to work with. Two spools landed on her desk, one a dark blue and black checkerboard vinyl, another smooth and silky gold.

Celly was gifted with pink cotton, not unlike that of a plush toy, and something red and white striped which crinkled as she poked at it, looking a little like her own diaper.

“Excellent!” Rarity said with a broad ~~fanged~~ smile. “Now you've got the fabric, which is the second step! You need to use these scissors, these needles, this thread-” her horn glowed as she levitated over one piece of equipment after another to each of the duo, and the list of tools sort of blended together into a drone which neither Celly nor Lulu actually remembered all of.

She kept talking, explaining how to cut fabric and pleat it, how to sew and stitch and crimp and darn, and Celly worked away on the pink cotton to make big ruffled shoulders… a section for her body barrel… four trouser legs… the big overhang for her diaper, and the bit which went up her front and her neck as well. As she did, Lulu was putting together something similar using the blue-and-black checker pattern – something making her want to put it together in ways which confused the eye, switching the checker back and forth every few rows so a pony's eye would get mixed up as they looked at it.

Lulu went on to add the ruffles, using the silky gold, and then the petticoats as well – four layers of them, which lifted up the back of the ball-gown she was making to frame her diaper in gold without actually concealing it.

“Excellent!” Rarity repeated. “You should always draw attention to your best asset, girls, and that is definitely your best asset!”

Celly and Lulu added their finishing touches, Celly tugging tightly on the thread to stitch together the red and white striped diaper cover where her diaper would be under the skirt, while Lulu was finishing sewing together matching stockings for her dress. “Marvelous work darlings! Now go try them on so we can see how you look in your new outfits.” Rarity urged, pulling curtains over to give them a bit of privacy.

The pair excitedly pulled on the dresses, Lulu's dress squeaking with every tug and movement. She wiggled her hips as her diaper slipped into place, presented proudly under her creaky skirt. Celly admired herself in the mirror, the ruffles of her shoulder pressing into her softly. As the two looked over their dresses, however, they felt just a little embarrassed. Despite how much fun they had making them, they hadn't given much thought to what exactly they would look like once they were on, and now that they were, they were even more silly and frilly appearing than they could have imagined.

It didn't help when their curtains suddenly disappeared, revealing the princesses to Rarity. She gasped, squealing ever so slightly as she looked them over. “Darlings, you're absolutely adorable! Why I don't know if I could do better myself!”

Celly blushed, though her embarrassment was offset a little as she giggled a little at Lulu's own appearance. “Hehe, are you sure you couldn't do better?” She asked.

“Well, since you ask...”

Rarity's magic picked up in a swirl of needle and thread, and several more strips of fabric came rising up out of the collection to the side. Celly saw red, yellow, blue, violet, orange, green, indigo, and then they all sort of merged together into a swirl as the white unicorn ~~with little bulges where wings would be~~ worked her art.

It was hard to focus on what was going on, especially as the wind picked up and lifted up the hems of their already-revealing ball gowns, and Lulu flushed brightly – then blinked a few times, losing focus as the swirl of fabric and gems cascaded around her.

When the spiralling material faded some time later, both ponies blinked – then did a double-take at the mirror.

Any hint of subtly hiding their diapers or their infantile dress was definitely gone, replaced by little touches and not-so-little ones which made the situation incredibly obvious. Celly's diaper had grown to at least half again the size, bulging up the whole gown, and she was wearing big Sun-patterned booties around her hooves which made it difficult to even stand upright consistently; Lulu's had a moon-pattern, but were otherwise the same, and she also noticed that she had a pretty little cover on top of her horn with a moon motif – matching Celly's sun-motif horn cover.

Lulu tried to use her magic, but the cover glowed, and her eyes went a little vague.

“Now, now, proper ponies don't disagree with the sartorial decisions of their dressmaker~!” Rarity said, as Lulu fell backwards onto her diaper with a loud crinkle.

“But these make us look really foalish,” Celly complained.

“Of course,” Rarity agreed matter-of-factly. “That's the in look this season!”

“Oh, I suppose that makes sense,” Celly said. Royals always wanted to retain their youth, after all, and what was more youthful than a foal? She didn't give it much thought beyond that, trying to waddle back to her seat, though the added bulk in her padding made that even more challenging. Not to mention her hooves slipping on the polished floor, forcing her into an awkward waddle and crawl to maintain her hoofing.

“And for the last part, the photoshoot! That way you can see how far you've come from just your first lesson!” Rarity said, producing a camera. She started to snap several photos, Lulu and Celly blinded by the flashes. They shook their heads, and when their vision returned, they were greeted by several snapshots of them flaunting their rumps and dresses, which Rarity was pinning to a cork board, and which only covered a worryingly small corner of the display.

“Now hurry off, the day's almost over. And you'll want to get as much sun in your life as you can!” Rarity smirked, hurrying the two out the door.

Lulu looked up to Celly, still a little discombobulated from the camera flashes. “Oh, uh... where are we now? Was that all the classes for the day?”

“I… think maybe?” Celly replied, trying to remember the timetable. It was always confusing for her to try and think about it, like it wavered in and out of focus, then she gasped. “Ah! I remember now, there was something else!”

“Oh, okay,” Lulu said. “So… what is it?”

“It's something that confused me,” Celly said. “Something about, um… oh, that's right, it confused me because I wasn't sure if it was a lesson or not. It's with Twilight, so it could be a closing speech or it could be a lesson.”

That made sense, and Celly nodded to herself in satisfaction – glad she'd worked out what it was. Then she began waddling along, Lulu hurrying behind her, through the school corridors.

After so many lessons, a lot of things which they might have noticed before didn't show up on their radar at all. The complete and total lack of any other students didn't seem suspicious, the large number of rooms for a school with so few students wasn't worth thinking about, and the way that they didn't actually follow a path through the school – just had a long perception of walking, before ending up at the lecture theatre for Twilight's timetabled slot – was perfectly natural.

“Ah, good evening,” Twilight smiled. “Isn't evening good?”

“I… yeah, I guess evening is good,” Celly said, taking her seat.

“That's right, that's very good of you to notice,” Twilight told her. “Now, your final lesson today is going to be on your test, so you'd better pay a lot of attention.”

Behind her, the chalk levitated up to draw on the board. “The lesson is all about different types of hypnosis.”

“Now, the most well known type of hypnosis involves somepony watching something, usually a small, shiny object, move in some sort of pattern.” Twilight pulled out a pocket watch, pretending to search the empty audience before focusing on Celly. “Would you mind coming up? I could use a volunteer to better explain this.”

Celly nodded, walking around to the steps at the end of the stage to hurry up to where Twilight was standing.

“If you'll just focus on this, you'll see what I mean. How the metal shines and sparkles, drawing your attention and blocking out anything else that might be going on.” Twilight began to swing the watch back and forth in her magic, Celly's nodding slowly as she focused in on it, completely unaware of the fact it would be hard for her to learn this hypnosis if she was supposed to be the target.

“Now, this hypnosis technique does have its drawbacks. It's fairly obvious and cliché, so anypony who knows about hypnosis will probably be unaffected, but this can easily be circumvented by attempting to hypnotize somepony when they're tired or focused on something else.”

By this time Celly was wobbling on her hooves a little, swaying back and forth along with the watch.

“Once the pony has been properly hypnotized, then you can start giving them suggestions, or implanting triggers. Do you know what those are, Lulu?”

“Oh, uh...” Lulu began, shifting a bit in her chair – her crinkly diapers rustling. “Suggestions sounds like they're saying things the hypnotized pony could do? Or will do?”

“That's very good,” Twilight agreed. “And triggers?”

“I… no, sorry,” Lulu admitted.

“Triggers are things where you give the pony an instruction, but it doesn't happen right away,” Twilight explained. “It happens later, or it stays in place. What do you think would be something that would be a good trigger or suggestion for Celly to have?”

Lulu frowned, trying to think of something which would be a good demonstration of hypnosis.

Naturally, something that was a good demonstration of hypnosis had to be something which would show that Celly really was hypnotized, rather than faking it… that seemed to make sense. Then Lulu giggled, as she realized there was a chance here to have Celly do something silly.

“Oh, I know!” she said. “What about a trigger so Celly thinks the right name for diapers is rustle-pamps?”

“That's a bit like a mixture of a trigger and a suggestion,” Twilight corrected. “But what would make it a trigger is if it was more like this.”

She continued swinging the watch. “Celly, if somepony asks about what you're wearing, you will tell them that you're wearing rustle-pamps. You won't think of them as diapers, you'll think of them as rustle-pamps, and you'll proudly explain why you're wearing them if anypony asks.”

Lulu watched as Celly nodded a little hazily, and could barely contain her giggles.

Twilight stopped swinging her watch back and forth, though Celly continued to sway a little bit on her hooves. “Now, once you end the hypnosis, they won't remember receiving their triggers, but they will remember them.” She turned back to Celly. “Now when I stomp my hooves, you'll head back to your seat and we'll continue with our lesson.” Twilight lightly stomped on the stage, Celly blinking and shaking her head.

“Oh... I hope the demonstration went well.” Celly said, her senses slowly coming back to her. As she turned to trot back to her seat, Twilight spoke up.

“It went very well. You did a good job showing off your... what do you call those again?” She asked, pointing to Celly's diaper.

Celly looked over her shoulder at her padding before grinning widely. “They're my rustle-pamps silly! Thick, crinkly rustle-pamps! They're the best things for keeping your butt comfy no matter where you sit!” She said excitedly, shaking her butt left and right.

Luna fell into a fit of laughter, trying not to fall out of her seat at Celly as she waddled back to her seat. Celly stuck out her tongue at Lulu as she sat next to her, her padding crinkling loudly as she flopped down.

“Very good, Celly, now you can see some more hypnosis. For example, you can implant triggers without the pony even noticing they were hypnotized, isn't that right, Lulu?”

Lulu's laughter died down as she tried to pay attention to Twilight's lecturing again. “...huh?”

“I hope you're paying attention, Lulu,” Twilight chided gently. “Now, as I was saying, you can give a pony a trigger without them even noticing they were hypnotized. It might be that they think the hypnosis session was a simple conversation, or a lesson, or they might not remember it at all.”

“Oh, I… I didn't know that,” Lulu said, blinking. “That's… huh.”

Celly giggled.

“What is it?” Lulu asked, looking over at her. “Is something wrong?”

“Oh, nothing~” Celly replied, still giggling. “It's just kind of funny that you didn't know that, that's all...”

“Why is it funny?” Lulu asked. “I don't get it, did I miss something? I thought we'd only just started the lesson…”

Celly giggled again.

“I'm surprised you're having so much trouble concentrating,” Twilight said. “Maybe it's because of the sound of the rain?”

Lulu blinked. “I… can't hear any rain,” she said.

“Can't you?” Twilight replied. “But there were definitely rainclouds outside.”

“I, um...” Lulu began to protest, but only a moment into talking she flushed suddenly – feeling a sudden urgent need, before sighing and relaxing. “Rain clouds mean things get wet...”

“That's right,” Twilight said, nodding – her eyes flashing a little. “So, you can see how a pony can have a trigger put in without their being able to remember it.”

Lulu frowned, not sure how what had just happened was relative to the lesson, then blushed suddenly as she realized how wet her padding was. She poked her diaper, ears going flat at the squishy noise.

“Um… sorry, Miss,” she said.

“That's all right, Lulu,” Twilight said. “It's what they're for.”

“It's what they're for,” Celly and Lulu repeated automatically.

“Now, let's talk about mantras,” Twilight added. “A mantra is something which a pony is given to repeat, sometimes as a hypnotic trigger, which makes it so they believe that thing more strongly. It's a good way to reinforce a hypnotic suggestion. Let's try something about how lovely the night is as an example.”

“The night is lovely.” Twilight said.

“The night is lovely.” Celly and Lulu repeated.

“The night means cozy diapers, and warm blankets.”

Celly and Lulu dutifully repeated this, finding everything Twilight was saying to be true.

“The more you repeat something, the more it sticks in your mind, making it easier and easier to simply find what you're repeating to be right. The night is lovely.”

“The night is lovely.” They repeated.

“And, something which ties in well to mantras is subliminal messaging. Not only are you repeating your thoughts, you don't even have to think about it! This is best done with quick flashes of messages, either audio or visual.”

As Twilight talked, Lulu and Celly thought they heard something about swelling padding and thick diapers, but they really couldn't be sure. They just kept thinking about how the night was good and lovely.

“Bah, but the better mantra, the better the hypnosis!” Another voice could be heard. A second Twilight was trotting up onto stage, looking equally as puffy as the first, though she was levitating her chalk in a soft orange glow.

“And everypony knows that the day is truly best! It means more light to show off your rustle-pamps!”

The two fillies nodded, Celly slightly more so than Lulu.

“And don't forget the classic spirals for hypnosis. The way they make you feel like you're slipping deeper and deeper into the suggestions!”

“Of course, any kind of conditioning can work,” the first Twilight said, sounding slightly miffed. “But everypony knows that the best kind of conditioning is the kind which mixes in triggers, so good little fillies can learn just how wonderful the night is.”

The sisters went all fuzzy when the first Twilight called them good little fillies, any lingering confusion about why there were two Twilights going away in a flash of swirly feelings and vague thoughts.

“But triggers can sometimes be used by a different pony to the hypnotist who first put them in,” the orange-magic Twilight countered. “So good little fillies would be able to learn how amazing daytime is as well.”

The blue-magic Twilight drew a series of spirals on the board. “Though it's night-time which is good for sleep-learning, subliminal learning which happens while the subject is a good sleepy filly and can't possibly resist anything which their hypnotist tells them.”

Lulu yawned at the words, imagining being all snuggled up while a nice voice whispered in her ears about how she was a good sleepy filly who loved the night.

“But there are other kinds of hypnosis which work best in the day,” the second Twilight said, drawing her own spirals with a different colour chalk. “A pony who's asleep can't watch a hypnotic film, or read a hypnotic script about how the day is the best.”

Celly giggled, following the chalk around and around in circles with her eyes and feeling fuzzier and blanker with every revolution.

The two Twilights continued to glare in each other's direction, each of the fillies watching fixated on a singular color of spirals. “But at night time one can dream, and dreams can be filled with whatever the hypnotizer wishes the fillies to see! Ah, not that you need to worry about dreaming, of course.” The blue eyed Twilight chuckled a little to herself as she addressed her audience. Neither Celly nor Lulu seemed to have picked up on what she had meant by that, instead thinking about dreams filled with fluff and puffiness.

“Bah, and surely you've heard of daydreaming too! When you're no longer paying attention to what you're being taught, so they can slip in whatever they wish. Then they get to decide where you take your adventures so that they remain just as fuzzy as blank as the dreamer is too...”

Eventually both ponies had filled their respective sides of the board with their spirals, now attempting to cover up the other's side.

Eventually the golden Twilight straightened up, smoothing her puffy chest out a bit. “Perhaps now would be a good time for a pop quiz. To help the fillies show that they've learned the day is the better time.”

The other smirked, pulling over some papers. “If you insist, but I do believe you'll find they know the night is the best.” The two began to scribble down questions, with Celly and Lulu's trance finally broken as their vision was filled with a questionnaire rather than the spirals of the chalkboard.

“Oh, um… I didn't study for this,” Celly protested.

“That's the best kind of test, of course,” the golden-magic Twilight said, her eyes flashing. “That kind of test tells you what you really know, not just what you read five minutes ago and forget five minutes later.”

She chuckled. “Not that remembering things should be something you should concern yourself with. Just answer the questions with what makes sense, and you'll be fine...”

“R-right,” Celly said, and looked down at the paper.

It seemed to swim a little in front of her as she blinked, trying to focus on the words.

There was a question about whether repetition helped hypnosis, and Celly thought about it before nodding – writing a 'yes' in the answer box.

Then there was the same question again, and Celly raised her hoof.

“Yes?” the turquoise Twilight asked.

“Oh, well… are all these questions right?”

“All the questions are right,” the golden Twilight told her. “Just answer them all.”

“Okay...” Celly said, and returned her focus to the questions.

As she did, Lulu turned over to the second page of her paper.

There seemed to be an awful lot of it, like one about which swirl was better, and she thought about them as she wondered how to answer – imagining both spirals at once, one red-and-gold and the other blue-and-green.

After several long seconds staring into space, she wrote down her answer and kept going.

Lulu looked to the next question, only for her eyes to glaze across it and not even realize where the answer was supposed to be put, let alone what the question was asking. She read the question, then read it again, then looked back over it once more to be absolutely sure she understood what it wanted. She finally came to some sort of conclusion, and wrote down 'gold' before moving on to the next question.

Celly was on the essay section of the quiz, though rather than writing anything down she blinked and found she had been half dozing off and doodling in the space provided. A series of spirals, stripes, criss-crossing and hatchwork to form a magic-eye picture was staring back up at her from the paper.

She glanced back to the question, then shrugged and moved on, finding that her doodle seemed to provide all the relevant information and anything she wrote down wouldn't do her answer justice.

She chewed on her pencil as she flipped through the packet, continuing her slow work. A lot of the questions seemed more like opinions than actually facts. But perhaps the questions were just the kind where one answer was 'more' right than the other. One Twilight flipped over an hourglass, announcing to the two fillies that they only had 5 more minutes before they would turn in their papers about how good the night was, only for the other to interject they were writing day essays. Neither filly paid much attention to their squabbling, as they were sure in their answers on which one was truly superior.

“And time's up!” one Twilight announced. “Were you good fillies?”

“I was!” Celly called, waving her hoof in the air, and Lulu nodded as well – proud to be a good filly like her sister.

The other Twilight collected the papers with magic, and they began looking through them – bickering back and forth about the interpretations of the marks, contesting whether an answer was a day-answer or a night-answer.

Lulu fidgeted a little as she waited to hear how it had gone, bouncing in her seat with a crinkle-squish sound. She could hear the two purple alicorns arguing over marks, but she wasn't even able to recognize which of the answers they were quoting to one another was from her paper – the whole thing was all fuzzy and kind of blank, and she wasn't really sure how she'd done or what it would mean.

Eventually, however, the flame-eyed Twilight and the cool-eyed Twilight seemed to reach a conclusion, though not without some grumbling.

“All right,” one said, taking a paper. “This one's mine, because she showed how much she agreed the night is the best!”

“Well, this one's for me, because she wanted the day,” the other one countered. “So there.”

Almost in unison, both Twilights flipped back to the front page of the paper, and paused.

“Huh,” one said, eventually, a smirk spreading across her face as she held the paper in her orange magic. “Who knew. Okay, Lulu, it's time for extra credit...”

Lulu jumped out of her chair, radiating excitement as she hurried after the orange magic Twilight. Celly instead followed the other Twilight, who was looking equally pleased with the results of her test. “I'm rather surprised, Celly, I didn't know you enjoyed the night so much,” she said.

“But it's so wonderful! The beauty of the stars, and especially the moon! Being wrapped up in covers and pillows and lots of fluff!”

Twilight laughed. “Oh, don't you worry, we'll get you plenty of fluff to wrap yourself in. And a very pretty moon to match it.”They soon stepped into a small private room not unlike the changing rooms where they received their uniforms at the start of the day.

“First we'll get your your new padding.” Twilight said, her horn aglow as she pulled open a drawer. Several thick diapers puffed out of it, each stuffed snugly into place. She slipped out one of the midnight blue diapers, a splotch of black on the rump with a bright crescent moon in the center.

Celly eagerly took the padding, sitting down atop it and wrapping it around her school padding before securing it to her waist. She rocked back and forth, her hind legs spread wide by the crinkly puff.

Lulu was admiring her new crimson sun emblazoned diaper as she waddled about, Twilight giving her a few comforting pats. “Now for the next bit, your new suit.” She pulled out a thick plush suit, one which looked an awful lot like her sister, but taller, more aggressive, and far, far puffier. These details only made Lulu giggle as she took the suit in her hooves, however, quickly unzipping the back to climb in.

It felt all snug and warm and plushy as she squeezed in – warm especially, as each hoof slid into the end of the matching leg of the suit and touched the area around the costume-plush shoe on the outside. Lulu felt a kind of hug, and a tingle spread up through the plushy costume, and she couldn't stop focusing just how bright and warm it all felt!

She giggled as Twilight helped her fit herself into the muzzle of the suit, then threaded her wings into the suit-wings, and as a faint crinkle-whisper filled her ears.

“There we go!” Twilight said. “You look much better now! You look like a true day-lover who knows that diapers by day are the best!”

Lulu smiled happily as the suit was zipped up, and only barely noticed the lenses in front of her eyes – lenses that were red and orange and gold, and that swirled faintly in her vision.

“But you know what the right name is for an alicorn who loves the day and the sun...” Twilight added, slyly. “It's not Lulu at all, is it?”

She blinked, unsure what Twilight meant, then a new name came to her.

“Of course!” she realized. “I'm Daybreaker! Or Daydiaper – or both!”

“That's right,” Twilight agreed. “You love the day, and you're so confident about that that you want to make sure as many other ponies as possible love the day and wear diapers as they love it. It's the only thing that's important to you, especially because it lets you show up Nightwear Moon...”

“...and Nightwear Moon is by far the better of the sisters, as you know. Much more comfortably plump and plush than that flat Daydiaper!” Twilight continued as she trotted around Celly to admire her new look. “You'll show everypony that the night is the best, and that they'll all enjoy the thick pampers that come with sleeping soundly and snug to keep them warm throughout the night,” she continued. Nightwear stood proudly in front of Twilight, a look of smug confidence crossing her face as she gazed upon herself in the mirror. “There's nothing to worry about, Twilight. I'm sure I can show everypony how much grander the night is.”

“Then the last thing to do is for you to greet your incoming students!” Twilight said to Daydiaper, leading her back out of the hall. The two regal puffy sisters followed their respective Twilights back to the auditorium. Several ponies were now crowded into the seats, each one looking equally confused as to how they arrived in their location, and why there didn't seem to be anypony at this school. Daydiaper and Nightwear Moon stepped up to the podiums, each smirking and doing their best to look all the more impressive than their sister.

“Welcome, new students! This year is going to be quite a fun one!”
