Author's Note

First half of the double update for this month. Since none of the votes were for combined chapters (back to back stories in each), they're being worked on separately. And this is the first one to come out. This also means that Rainbow Dash now can only be done with Wonerbolts other than Soarin, or with other members of the mane six/seven (Starlight is ineligiable for consideration under any circumstances).

This time around, it was actually superfun who proposed the idea. He (or she) specifically proposed Rainbow Dash first and Soarin second, and Soarin being mentioned as part of the duo elevated Soarin above the competition. The idea was that Rainbow Dash needed a break from leading the Wonderbolts (in this AU she was made captain much sooner), and wanted Soarin to do it with her with her in the role of big sister and Soarin as the little brother.

Seeing as this is in an AU around Season 5/Season 6, Rainbow Dash's parents aren't necessarily canon to this continuity, but I did still want to elude to them indirectly since I imagine their parenting style might indirectly affect how Rainbow feels about being pampered and treated like a foal again. As for Soarin, I mostly went with the headcanon of his mother being Amy Keating Rogers' OC pony, seeing as Amy said she named Soarin after her son.

I'll update the voting totals once the Sunset Shimmer chapter is also uploaded.

Princess Celestia now held aloft in the glow of her horn something special that she wanted to give Twilight. Something she had specifically asked Rarity to design, and something that she had first started thinking about after seeing Moondancer wear one. It was a lavishly detailed, highly stylized onesie that was a bright hue of baby pink. It featured plenty of room to fit Twilight's diapered rear, and had a zipper pouch in the back to make diaper changes much easier.

Twilight all but jumped up and down in excitement when she saw the aforementioned onesie be presented to her! "Oh thank you, Mommy!" She giddly remarked, leaping up and nuzzling the sun princess in the chest the same way an actual foal might hug its mother.

Celestia smiled, returning the display of affection full force, even draping a wing over her fellow alicorn in the process. "You're quite welcome, Twily. It was my pleasure. It was the least I could do after how well behaved you've been recently. Plus, now you'll have a way to keep your secret safe from prying eyes," She carefully floated the onesie into Twilight's hooves and clapped her hooves while cooing. "Go ahead, try it on. I need to know whether it needs to be sent back for some..." She coughed into one of her hooves. "Adjustments."

The padded princess didn't hesitate to slip the aforementioned pink garment over her padded posture, delighting in how it seemed to make her rear sink even further into the crinkly undergarment hugging her bottom, and how it seemed to push her legs apart even more and make her waddle about the way an actual foal would do. She giggled as she gave her now covered padded plot a shake, and then patted the seat with a hoof. "It's perfect, Mommy! I'll do my best to keep it from getting dirty." She said as she gave something of a cute salute.

The sun princess smiled. The affection from Twilight felt only slightly exaggerated, and that absolutely warmed her heart. She knew it was probably not what Luna might want, to get even more attached to Twilight in this role, but Celestia just couldn't help herself. When Twilight was all padded up like this, she was just too cute. Who in their right mind could refuse or say no to her without a great deal of effort?

Princess Celestia, however, then opted to use her magic to carefully remove the new onesie and set it aside. "Well, I'll need to wash it first so it's nice and clean for you, Twily," And she was quick to warn. "It can still be taken away if you act up, so please remember that."

Twilight nodded. "Uh-huh, I'll be good, Mommy."

The elder alicorn smiled back, satisfied that Twilight would sincerely keep her word. And that allowed her to turn her thoughts to other matters of importance: Namely, who would be the next playmate for the padded princess in her care. By chance she turned and gazed out of the bedroom window, looking to the skies above.

The diaper wearing princess slowly waddled over (even though she had no real need to do so). "Is everything okay, Mommy?" She asked her fellow alicorn.

Celestia, for her part, kept watching the skies. "Well, there are some ponies I was expecting to see by now. But it seems they either got lost or were delayed in departing," She shrugged her hooves and turned slowly away. "Oh well. I suppose I shouldn't be surprised, they are rather busy right now."

Yet no sooner had the two alicorns turned their gazes away from the windows, then did there come what sounded like thunderous roars, followed by audible screeches, and then thuds! Two pegasus ponies clad in navy blue flight suits and flight goggles had impacted the bedroom window, and were now slowly skidding downwards towards the ground below.

Thinking quickly, Princess Celestia opened the window and used her magic to pull the pair of pegasi inside, before shutting the window again (after making sure nopony had their gaze fixed on said window, they would surely think something was up if they saw her snatching ponies through windows). She quickly checked them over to see if they were hurt, and breathed a sigh of relief when she saw that they both appeared to be dazed but not harmed to any meaningful extent.

"What was the big idea, Crash?!" A goofy, male sounding voice complained as an azure colored hoof then lifted up the flight goggles on one pony to reveal a set of moderate emerald green eyes. "I told you we didn't have to fly so fast!"

A familiar, feminine and somewhat raspy sounding voice retorted. "First of all, Clipper, we had to fly fast because I didn't want us to be late for the princess," Then as a familiar light blue colored hoof lifted up the flight goggles on the other pony and revealed a set of moderate purple eyes. "We were late because of all that paperwork I had to sign. And for the record: I told you not to call me Crash, especially not in public! I'm your captain now, you're supposed to do as I say."

"'Crash'? 'Clipper'?" Twilight blinked in confusion. She knew for sure the identity of one such pony speaking, and was certain she'd heard the other voice somewhere before. But the names were confusing her.

The feminine sounding pegasus pony groaned and sighed, looking across to the goofy, masculine sounding voice. "Great, see what you've started?" She turned to the padded princess and cleared her throat. "Whatever, let's just get these introductions over with. I still can't believe I agreed to this, even if I did need a break." The two pegasus then promptly pulled the navy blue flight suits right off their bodies, allowing the sweaty, smelly spandex to crumple to the floor. Now standing before the two alicorns was a very familiar looking rainbow maned pegasus mare, and a pegasus stallion with an azure coat, a very dark grayish-blue mane and tail in something of a buzz cut, and a cutie mark depicting a lightning bolt going through a cloud.

However, the cutie marks on both pegasi were only faintly visible through the very thick diapers they were wearing, both of which looked like they'd gone through a good soaking given the damp patches on them. Yet neither pegasus seemed to be bothered by the added bulk, or by the damp feeling they were undoubtedly experiencing right now.

Twilight's eyes went wide as she let out a gasp! She'd heard about these two from Spitfire, and had even interacted with one of them before then! She was now face to face with Rainbow Dash and Soarin, both of whom had been wearing diapers underneath their Wonderbolts flight suits, almost as if they'd flown straight over from the academy itself.

Soarin giggled, swishing and shaking his padded posture. "Well, I'd say she's taking it pretty well, huh Crash... I mean Dash."

For a moment or so, the padded princess found herself at a near loss for words. "How... I mean what... I mean..." True, she could already pretty much piece together why the two were here, but she was still surprised to see them all the same, in diapers no less.

Soarin was the first one to answer the princess' puzzled pronouncement. "Come on, Twily. We're here to be your playmates. Your mommy told us already."

Rainbow Dash groaned, putting her hooves to her face. "That's only partially true, Soarin. She'd been begging and pleading with me to come back and play with Twily some more because she had to trick me and regress me against my will last time," She let out a sigh, plopping onto her padded posture whilst ignoring the squishing sensation that came as a result. "I didn't really want to. But then I started thinking about it more: And it was kind of relaxing. Plus, ever since I got promoted to captain of the Wonderbolts, I've had so much on my plate that I could really use some downtime."

Soarin, meanwhile, adopted a goofy grin. "Yet she would only agree to do it if I went along with her. She asked me to do it because I'm still second in command, whereas Spitfire's basically stepped aside and only comes in to fly with the team as needed. I'll give Crash... I mean Dash credit, she's proven to be a much better captain than a lot of the other Wonderbolts were expecting."

"Soarin, how many times are you gonna keep calling me that?!" Rainbow complained in an annoyed tone of voice. "I thought I made it clear when I took over that that was a Wonderbolts tradition we didn't have to keep doing, like what you used to use the 'special academy bathrooms' for when punishing certain cadets."

Soarin quickly whispered to Twilight. "You don't wanna know, it's not pretty," Then he was quick to apologize to his superior. "Sorry, I guess old habits are hard to break. Still, it means a lot that you'd ask me to do this with you. Not that I have a problem with being back in diapers. Don't see why so many of the other 'bolts complain, it beats having to wait in long lines for the bathrooms before and after shows," Poking his padding with a hoof, he said with a smile. "Instead, you just keep on flying and let it all out, and nopony's ever the wiser."

"Until you have to change yourself," The rainbow maned pegasus mare groaned and gagged. "It's really not pleasant. That's why I made Lightning Dust our official team changer: Figured it was the best way to keep her out of trouble until I know I can trust her not to go overboard. It may not be pretty but... well, somepony's got to do it. And for some of the Wonderbolts, hiring a designated changer was the only way they'd agree to stay on the team. It was either that, or I made bathroom breaks mandatory for long flights. I went with what I felt was the lesser of two evils."

The Wonderbolt co-captain just giggled in reply. "Aw come on, Rainbow Dash. You don't have to lie. You could've tossed that diaper rule as soon as you became captain, but you kept it on because you saw as well as Spitfire and I did how diapers could have their uses."

Twilight giggled back in a playful tone of voice. "Oh I know. I mean, using the potty can be great too. But having a potty you can take with you anywhere and not have to worry about it is such a huge relief."

Rainbow simply sighed. "Well, whatever, the whole team's on break now. Spitfire can handle any emergencies that might pop up," She then turned to Soarin. "We both agreed this stays between us, Soarin. I'm the big sister this time, you're the little brother. So what I say goes!"

Princess Celestia came trotting up at that very moment. "Careful now, Rainbow Dash. Don't think I've forgotten how much of a hooful you were the last time you were, playing with Twily. You have to agree to do whatever I say," Her tone of voice briefly took on a more serious undertone as she warned. "And you know what will happen if you act up."

At that, the brash speedster swallowed hard and shrank from the sun princess' gaze with a faintly audible "Eep".

Celestia quickly went back to her gentle, motherly sounding tone of voice as she cooed. "Good, seems we understand each other," She then trotted over to Twilight and inspected her fellow alicorn's diaper. "Now, let's just see if you need a change too, Twily. We wouldn't want anypony here to get a rash before play time has even started."

"Don't worry, Mommy. I'm dry." Twilight insisted as she allowed her diaper to be pulled back and examined quite carefully.

The alicorn mare with a white coat the same pristine white as the diaper smiled upon seeing that her charge was telling the truth. "Well done, Twily!" She showered the diaper wearing princess with exaggerated praise, even playfully patting her head. "Why don't you go keep Smarty Pants company while I take care of your new 'big sister' and 'little brother'?" She proposed as she then trotted over to the two padded pegasus sitting before her.

Twilight nodded and playfully waddled away. "Okay, Mommy. I can do that."

Satisfied that her fellow alicorn would stay out of trouble (and out of sight of prying eyes), the sun princess approached Rainbow Dash and Soarin, quickly taking hold of both of them with the soft, golden glow of her horn. "Alrighty, then. Let's get you changed out of those soggy diapers. Don't worry, Twily has plenty of spares for you two to borrow."

"I just hope they're as absorbent and poofy as the ones we were wearing under our flight suits," Soarin commented. "Thick and poofy diapers are the best!"

"Whatever, it's not like I'm gonna actually use them again. If Soarin hadn't insisted we rush over here, I would've gone to the bathroom before we suited up." Rainbow grumbled. Nevertheless, she didn't make a fuss or try to fight back as she was floated onto the changing table next to Soarin. She and her co-captain were soon stripped of their diapers, which were bailed up and tossed aside without fanfare. Then their rumps were thoroughly wiped and powdered, before two new diapers were floated on and strapped to their bottoms.

"There we go, all nice and clean again," Celestia cooed as she lifted both off-duty Wonderbolts off the changing table and set them gently upon the floor. "Just remember to ask me if you need anything. And be nice to Twily. If you play your parts well, I'd be more than happy to give you both a reward."

Rainbow shrugged her hooves. "Eh, I'm pretty happy as it is. Even being captain is pretty awesome: It's just all the little things that I really don't like bothering with. They seem so unnecessary. I don't know how Spitfire could do it all and make it look so easy."

Soarin waddled over and draped a wing around his teammate. "Hey, don't worry about it, Dash. You'll get the hang of it eventually. Even if the other 'bolts are still getting used to it, I'm glad to have you as a captain. Spitfire made the right choice."

The brash speedster slowly nodded. "Yeah, I guess she did. And it's not like she's gone forever. She's still on hoof to help out. Plus," She put a hoof to her face and couldn't resist letting out a giggle. "She's been getting pampered a lot too from what I hear."

The alicorn mare with a majestic white coat just flashed a knowing wink. "Well, I felt they would both appreciate a chance to feel young again," Then she ushered her charges towards Twilight. "Now then, my little ponies, what do you feel like doing today?"

The rainbow maned pegasus fiddled with her hooves as she sat on her newly powdered and padded posture, deep in thought. She thought, and thought, and thought some more. Just sitting there, tapping a hoof against her chin. But after a while, she stood up and let out a groan. "I've got nothing! I've been so busy just thinking about the diapers and stuff that I haven't had time to think about anything fun to do. Is it any wonder why I decided to do this? I've been so frazzled lately! I just don't do well when I'm all cooped up in some office somewhere, filling out paperwork, signing autographs, and doing all the boring but important stuff I know a captain's supposed to do."

"Sounds a lot like what Mommy does on a day to day basis," Smarty Pants chimed in. "Or what Princess Luna sometimes has to do."

Twilight just grinned and giggled. "Well, that's why she's here now. Dashie needs to take a break from all that no fun grown-up stuff and just have fun, like you and I, Smarty Pants."

Smarty Pants nodded back. "Exactly, Twily. Grown-up stuff is boring, it's not for little ponies like you and I. It's for mommies and daddies and other big ponies to worry about."

Soarin, meanwhile, seemed to be absent mindedly sticking his hoof into his mouth and suckling on it. It was clear that he was more or less trying to "get into character" as it were. And it didn't seem to bother the azure coated stallion that he was starting to drool ever so faintly as he did so. Yet suddenly, he pulled his saliva covered hoof out of his mouth and proclaimed in a childish sounding voice! "I know, we should all go for a fly together! I find that there's nothing more relaxing and stress relieving than going on a long fly somewhere. Plus," He once again patted his padding. "We're already wearing protection."

But Twilight flinched at the suggestion, and so did Rainbow Dash. Their eyes went wide with what seemed like horror!

"Ooh, I don't think that's a very good idea, Soarin," Smarty Pants chimed in with her own sentiments. "Ponies might see you in your diapers. And I don't think Twily would want that."

The pie loving stallion blushed as the realization struck him all of a sudden. "Oh yeah, guess I kind of forgot about that," He started thinking again. "Maybe we could just fly around in this bedroom? We could pretend to do our own little Wonderbolts show."

Celestia shook her head from side to side, voicing her disapproval. "Absolutely not! The ceiling is too low and there's far too many obstacles lying around that you could bump into."

Rainbow protested. "But we can't fly outside, not even if we put on our uniforms. Twily won't have anything to cover up her diaper. If anypony saw it or took pictures, everypony would find out. They'd never take her seriously again."

The padded princess shut her eyes and shuddered, picturing just such an image in her mind. She could already hear the jeers, the taunts, and the cruel laughter from all those stuffy nobles and delegates.

"Twily, it's okay!" Smarty Pants moved to quickly reassure the frightened princess, slowly moving a hoof out. "That will never happen. Mommy will never allow it!"

Twilight opened her eyes, sniffling slightly. "I know... but still..." She trailed off, deciding it best not to dwell on the matter.

Luckily, it was Princess Celestia who came up with the solution. "Well, I believe I know of a place within the castle that should suit all of our needs: It's big enough to have plenty of room for you to all fly around. But it's also secluded, so nopony will come barging in uninvited. We'll have total privacy, and Twily's secret will stay a secret."

"And where would that be?" Rainbow Dash pondered.

The sun princess quickly explained. "I was referring to the royal observatory. It hardly ever sees use anymore, aside when Luna wants to look at the stars more closely. Even then, she only ever uses it at night or in the early morning. The rest of the time, it just sits there unused. I will obviously have to move some of the heavy equipment, but that shouldn't take long," Turning to the three padded ponies in her care, she sweetly inquired of them. "Would that be okay with you, my little ponies?"

All three nodded back, Celestia taking nods as a yes. "Good, it's all settled!" She declared as she brought her hooves together. "But before we worry about that, let's get you all fueled up. I'm sure you all must be hungry by now."

As if on cue, a trio of rumbling stomachs reached the trained ears of the elder alicorn. And so it was that she quickly teleported them all to the royal dining room.

Once in the dining room proper, Celestia quickly fixed bibs around the necks of Twilight, Rainbow Dash, and Soarin. She was especially pleased that Rainbow wasn't trying to fight her, and was being more cooperative about the whole thing in stark contrast to her behavior from last time (Rainbow still having her adult mind certainly helped). "Alright," She said afterwards. "You all stay here. Mommy will be back shortly with the num nums." And then she disappeared into the kitchen.

Soarin, for his part, just leaned back in his chair, letting his rear slowly sink deeper and deeper into his padding. He seemed to be having the time of his life. "You know, this really takes me back." He said in such a casual, unconcerned tone.

"It does, does it?" The currently off-duty captain of the Wonderbolts questioned. She sounded genuinely curious about such a statement if the odd look on her face was any indication.

The azure coated pegasus stallion nodded. "Yup. I'm not ashamed to admit I probably took a little longer to fully get out of diapers than most ponies my age. My dad was almost always away due to work, so Mom mostly stayed home and raised me with love," With a chuckle, he boasted. "I had her practically wrapped around my hoof. There was almost nothing she wouldn't do for me," Then he sweetly smiled, closing her eyes. "But what I remember most about her was her singing. She had the most beautiful voice."

"Like how when I used to sing to Twily?" Smarty Pants asked.

Soarin shrugged his hooves. "Maybe, I guess. She would sing to me every night to help me fall asleep, or when trying to get me to take naps," He fondly recalled. "The only thing that ever came close to topping her singing was her cooking. She could make anything yummy, especially pies," He licked his lips and started to drool. "Oh yes, I LOVED her pies! It's why pies are my favorite food: They remind me of her. And being back in diapers like this," He fondly sighed. "It's like I'm a little foal again, entirely in her care: Safe and secure."

Twilight happily nodded. "That's what any good mommy should do for her babies. My first mommy always told the best bedtime stories, because she used to be a writer and an author. And she always did the funny voices too. Then of course, there's my other mommy," Her tone of voice changed as it became clear who she was referring to. "She's even better. She's always there for me no matter what, she even lets me drink her milkies."

At that Rainbow Dash's eyes went wide with shock! "No way! She does that?!"

"Hey, that's what mothers do for their foals, isn't it?" The Wonderbolt co-captain pointed out.

The brash speedster's cheeks flushed pink as she realized how overly dramatic her outburst had been. "Sorry, that just... caught me off guard, was all. I wasn't really expecting to hear that."

Soarin then saw fit to ask. "What was your mommy like, Rainbow Dash? You did have one, right? And probably a daddy too?"

Rainbow's response took her fellow padded ponies by surprise. She gulped and swallowed hard, suddenly trying to adopt a faraway look. "W-why do we need to talk about that? I... I don't see why we should. I mean, yes, I have parents. But we just have a..." She paused, trying to think of a good word to describe her bond with two ponies she hadn't seen or spoken to in many years. "A-a delicate relationship, that's all. I don't hate them. I just... don't really feel the need to talk about them: You know. We stay in touch more or less."

"Really?" The pie loving stallion pondered. "Then how come I haven't seen them at any of our shows since you became part of the team? Seems like everypony else's parents have been to at least one show."

The rainbow maned pegasus mare swallowed hard once again. "W-well... they're just... really busy with... their interests. I did send them a letter about making the team," She fiddled with her hooves and tried to adopt the most innocent looking expression possible. "I-it must've... gotten lost in the mail... or... or something." It seemed clear that she wasn't telling the whole truth for some reason.

Before either Twilight or Soarin could press Rainbow Dash on her suspicious skirting of the issue, however, the dining room doors were flung open. Princess Celestia came strolling in, carrying several gleaming trays piled high with fresh, steaming vegetables. And the aroma from them wafted through the air, making the mouths of her charges all collectively water at once.

"Alright, everypony," Celestia cooed as she sat down in a seat, Twilight seated off to her left and Rainbow Dash and Soarin off to her right. "I've brought the most high quality vegetables, all cut up just for you. If you're going to be flying through the skies and doing daredevil stunts, you're going to need your nutrition," She then warned. "And none of you are leaving the table until you eat everything on your plates: No ifs, ands, or buts."

Both Twilight and Rainbow seemed satisfied with the offerings (though one was more enthusiastic about it compared to the other appearing to be more or less resigned and reluctant). But Soarin took one look at his plate and frowned, pushing it away. "Can't I have something yummier?" He asked. It was hard to tell if he was just playing, or if he really meant it.

The sun princess shook her head from side to side in disapproval. "I'm afraid not. This is all you're going to get," She eyed the pie loving stallion and warned. "That's not going to be a problem for you, is it?"

The diapered stallion with an azure coat hesitantly replied. "Even when my mom made me eat them as an actual foal, I hated vegetables. I just don't care for how they taste. I'd rather eat almost anything else, really."

The alicorn mare with a majestic white coat then offered. "Well, how about this? If you cooperate and eat all your vegetables without making a fuss, I'll see about asking the chefs to whip up something sweet for you and for your playmates: Deal?"

After hesitating for about a minute or so, Soarin flashed a toothy smile as he said quite eagerly! "Deal!" And just like that, any reluctance on his part completely disappeared as he began to chow down on the vegetables, crumbs flying everywhere in the process.

The rainbow maned pegasus couldn't resist laughing herself silly at such a sight. "I thought he just did that when he eats pies. But apparently, he's always a messy eater!"

"Good thing you're not like him, Twily." Smarty Pants commented.

Twilight and Rainbow Dash then ate their vegetables in much more orderly fashion, though their faces still got a few crumbs here and there by the time they were done.

Rainbow leaned back in her chair afterwards and patted her belly, delighting in how nice and full it felt. "Oh, that hit the spot!" Then, almost as if by instinct, she let out a loud belch. "Excuse me." She managed to force out.

Celestia, for her part, just chuckled while using a wet rag to wipe off the trio of padded ponies' faces. And to Soarin she then said. "A deal is a deal, I'll tell the chefs and see what they can do."

"Can it be a pie?! Preferably an apple pie?! Apple pies are the best!" Soarin firmly insisted as he wiggled around in his seat, shifting his weight as his bottom had by now sunk fully into the rear of his diaper.

The sun princess nodded. "Okay, an apple pie it shall be. In fact, I'll make it three apple pies: One for you, one for your captain, and one for Twily of course."

"But what about you, Mommy?" The padded alicorn asked. "Don't you want an apple pie too?"

Princess Celestia sweetly replied. "Oh no: I'm really more of a cake mare than a pie mare," Then she rose from the dining room table. "I'll just pop in to have a word with the chefs. Then I'll ask you all to remain in the bedroom while I get things set up for your little Wonderbolts show." And she was as good as her word.

Afterwards, time seemed to pass in agonizing slowness as the three padded ponies stayed in the bedroom and waited for Princess Celestia to return.

"Ugh, what is taking her so long?!" The brash speedster mare complained. She even went so far as to put her hooves up to her face as she groaned. "This is so boring sitting around here, waiting."

"It's just like when Mommy makes me sit on the big potty, even when I don't want to." Twilight remarked as she started pacing back and forth.

Soarin didn't seem bothered. "Hey, come on, now. We promised her we'd be good and would wait for her. Let's just find something to do to pass the time until she gets back," He quickly proposed. "I know: Let's play tag! This room's big enough for it!"

Rainbow immediately spoke up! "Great idea, Soarin! And since you proposed it, why don't you be it first?" She then took off, flapping her wings and zipping away! "Can't catch me!" She taunted in the most childish tone of voice imaginable.

The azure coated stallion whined only somewhat playfully. "Hey, no fair!" He quickly flapped his wings and tried to chase after her.

Twilight giggled, patting her padded tush and taunting! "Can't catch me either, slowpoke!" And she ran away too!

"Aw come on, I am not slow!" Soarin complained! Yet he decided to focus his efforts first on trying to catch Rainbow Dash, determined to pay her back.

The currently off-duty Wonderbolt captain delighted in making her co-captain and fellow Wonderbolt chase after her. "Come on, Soarin! You needed the exercise! Otherwise, you'd get all slow and fat!"

"Make another crack about my weight, Dashie!" The co-captain snorted. "See what happens!" He then narrowed his eyes and lunged forward, ultimately succeeding in tackling his "big sister" to the floor. Then he sat down right on top of her, planting his padded posture firmly upon her body. "Now take back everything you just said, or you can forget about getting up."

Rainbow Dash growled and groaned. "Now you're the one not playing fair, Soarin. Get off of me, or I'm gonna make you sorry!"

Soarin playfully taunted. "Nu-uh." And he pressed the full weight of his diaper down further, whilst also leaning down to tickle his fellow padded pegasus with his hooves.

The rainbow maned pegasus mare howled with laughter, kicking and screaming about with tears in her eyes. "S-stop it! Please!" She pleaded in between fits of hysterical laughter, trying in vain to break free. When she saw Twilight off in the distance, she pleaded. "Twily, help me! Soarin's being a poopy head!"

Twilight waddled over, adopting a cheeky grin as she decided that instead of helping her friend she would join Soarin in tormenting and tickle torturing Rainbow for a bit. After all, she still had a little bit of pent up frustration from when the brash speedster had gotten them both into trouble the last time she'd been Twilight's playmate. "Say you're sorry, Dashie!" She demanded.

"Nu-uh, not gonna do it!" Rainbow Dash insisted. As much as it was now hurting her to laugh, she would not give in.

So it was that the tickling and the teasing went on for what felt like a good while. Neither Twilight or Soarin showed any signs that they were going to yield or cease.

Yet suddenly, an ominous sensation made itself known to the rainbow maned pegasus! Almost on instinct, she shot up, pushing Soarin and Twilight off her and sending them both stumbling to the floor! She clutched her stomach with a hoof as she struggled to keep her legs from spreading apart and adopting a squatting posture. "No no no no no!" She said again and again with a strained look on her face.

"What's wrong Dashie... I mean Dash?" Soarin was the first one to ask upon noticing his teammate's troubled expression.

The brash speedster didn't answer with words. She instead made more or less a mad dash across the room until she reached the bathroom door, frantically pawing at it and trying to get it to open! "Come on! Come on!" She whimpered as her face seemed to turn red.

The padded alicorn trotted up to her friend, telling her. "Sorry, Dashie. Mommy locks the bathroom door when she's not around. We're not allowed to go in there without her or another trusted grown-up."

"You gotta be kidding me!" Rainbow complained and moaned. "I really gotta go!"

Soarin tried to reassure his frightened fellow pegasus. "It's okay, Rainbow Dash. Just let it all out. My mom always used to say when she was potty training me that it's not good to hold it in all the time."

Twilight nodded. "Uh-huh. B.B.B.F.F. and Mommy always say the same thing. And you know foals can't use the potty anyways without an adult to supervise them."

Realizing that there was no choice, Rainbow sighed and resigned herself to the inevitable. "F-fine," She forced out. "But I'm not changing myself! That's the one thing I hate most of all about this, even more than what I'm about to do," She spread her hooves out and began to adopt a squatting posture. As she did so, she asked her fellow padded ponies. "Uh... c-could you... look away, please?"

Soarin nodded. "Sure thing, Dash." He quickly turned his head, and noticed Twilight doing the same after making sure Smarty Pants had a hoof thrown across her eyes so that the doll wouldn't be able to see what was about to happen either.

The rainbow maned pegasus felt her tail hike upward as she grunted and began to push! Even with all her time as a Wonderbolt, she had yet to actually do this in her diapers. It took her a long time to go against years of potty training, but finally her efforts were rewarded with the sound of crisp crinkles as she relieved herself: Her body feeling empty afterwards and her diaper feeling nice and full. Within seconds, however, the stench of manure reached her nostrils and made her want to gag. It was so overwhelming and overpowering!

Twilight and Soarin, without saying a word, looked to each other and then did the same thing they'd seen Rainbow just do. Unlike her, they had very little trouble getting their bodies to cooperate. And soon, their diapers were full too.

"You guys didn't have to do that for me, you know." Rainbow pointed out afterwards.

"Hey, when you gotta you gotta go," The azure coated stallion replied as he ran a hoof through his mane. "Don't you feel better now that you've gotten it all out? And wasn't that better than having to run to a toilet?"

The brash speedster sighed deeply. "I... guess so. But still... this is so gross!"

Luckily for the three padded ponies, Princess Celestia reappeared in the bedroom at that very moment. And as soon as she caught a whiff of the air, she knew what had happened. "Oh my goodness!" She exclaimed, dramatically fanning a hoof across her nose as she hastily summoned up a clothespin and put over her nostrils to block out the stench. "It seems I have three very stinky foals to deal with."

Fortunately for all involved, Celestia had the dirty diapers changed in a matter of mere seconds. She even made sure to double bag the trash bin she threw said dirty diapers into. "Perhaps I should look into getting a diaper pail," She thought aloud as she then wiped her charges clean, thoroughly powdered them, and then put new diapers on them and helped them to stand. "Sorry for being gone for so long, my little ponies. There was a lot more stuff that needed to be moved out of the observatory than I thought. I should probably have a talk with Luna about not leaving things just lying around so much."

"So, is everything ready for us now, Mommy?" Twilight asked after the diaper changes were complete.

The sun princess happily nodded. "Indeed it is," She then floated over a special pair of pajamas intended for a full grown pony like Twilight. They were designed to resemble the flight suits worn by the Wonderbolts, but had room in the back to fit the extra weight of a diaper. "And what Wonderbolts flight show would be complete without the uniforms? Now you can look the part just as much as you'll act the part, Twily!"

Twilight giddly jumped up and down, kicking her back legs in excitement! "Oh thank you, thank you, THANK YOU, Mommy!" She hastily snatched up the pjs and somewhat clumsily slipped into them as best she could. She giggled afterwards as she "pretended" to pull down her flight goggles and zip up her suit.

Rainbow Dash and Soarin, meanwhile, went and put their flight suits from their earlier flight to the castle on. "Knew we were forgetting something," Rainbow muttered under her breath. "Maybe we should've had these washed."

"We'll definitely have to take care of that when we get back to the academy," Soarin agreed. "Otherwise, Spitfire's gonna chew us out for sure."

"Okay, everypony, are you ready?" Princess Celestia asked once all three padded ponies had gotten properly suited up.

The three suited up fliers all nodded together. "Yes we are!"

The alicorn mare with a majestic white coat smiled, beaming happily. "Good! Let's get the show underway, shall we?" Then, with a quick flash from her horn, she teleported them all to the now cleared out and vacant royal observatory. The whole place was essentially a wide open dome, with plenty of room for three ponies like Twilight, Rainbow Dash, and Soarin to fly around to their hearts' content.

Rainbow, pretending she had her whistle on her, gave a shout! "Alright, Wonderbolts, follow me! Do exactly what I tell you to do, do I make myself clear?!"

"Ma'am, yes ma'am!" Soarin and Twilight sharply rapped as they fired off a quick salute to their designated leader. Then, flapping their wings, they followed the brash speedster as she flew up all the way towards the roof of the observatory. Then she dove back down, and pulled up again seconds before she would've made contact with the ground!

What followed was a series of rapid dives, climbs, turns, spins, and other impressive aerial tricks that were almost too fast for the naked eye to see!

Princess Celestia watched the whole thing unfold, occasionally clapping, cheering, and adding her own sentiments to break what was otherwise silence.

Occasionally, Soarin or Rainbow Dash would break off to do their own little thing independent of the others. But Twilight never once deviated from the standard routine, imitating whatever she saw her fellow fliers doing.

The grand finale for the impromptu flight show saw Rainbow fly up as high as she could, practically touching the ceiling. Then, gritting her teeth, she pushed herself down as fast as she could! A rainbow colored shockwave soon shot out from behind her, accompanied by a deafening roar! The shockwave itself faded after just a moment or so, lacking any sort of sky to stay in. But the performance was still a sight to behold for the brief amount of time it had been there.

Celestia waited for her charges to slowly fly back down to the ground afterwards, watching as they all lifted up their goggles one by one. "Bravo! Bravo!" She applauded. "What brave little ponies you were. Never have I seen such daredevil displays of dazzling daring do. That was the best Wonderbolts show I've ever seen!"

"Aw, thanks. I'm always happy to delight the fans," Rainbow insisted as she tried her best to be modest. "To be honest, even I'm surprised at how easy it is for me to do a sonic rainboom now. I guess that's just how good I've gotten at pushing past my limits."

"Being on a team like the Wonderbolts'll do that to you," Soarin pointed out. "And it's performances like that prove you'll be just as good a captain for us as Spitfire was, maybe even better."

The brash speedster and off-duty captain just replied. "W-well, don't forget that if it wasn't for your encouragement, Soarin, we wouldn't even be here right now. I never could've worked up the courage to go back to diapers again without knowing I had somepony as trustworthy as you to go through it alongside me," She sighed. "It's funny, now I feel like what I went through with my parents growing up actually wasn't that bad, even if they could go too far sometimes."

"Oh?" Smarty Pants asked (she had been brought to the observatory with Twilight, but had remained a silent observer).

The rainbow maned pegasus began to fiddle with her hooves as she confessed. "Well, like Soarin and Spitfire from what I can piece together, I was an only child growing up. I don't know if my parents just never wanted to have another foal, or if something happened that made them unable to. Whatever it was, they were really affectionate with me. Too affectionate, to the point where it stopped feeling sincere. It felt like deep down, if every little thing was worth celebrating, they were really saying that nothing would ever be good enough for them."

"So they took it too far in praising you?" Smarty Pants inquired. "Like celebrating every time you so much as talked or used the potty?"

Blushing a bit, Rainbow admitted. "Something like that. They didn't really start doing it until after I was out of diapers, not really sure what changed then. Anyway, I tried to talk to them, but they just wouldn't listen. And so, as soon as I was old enough, I moved out and moved away," She nervously went on to add. "Until now, I thought it was the right choice to make. But after today... I'm starting to wonder if maybe I didn't make them see how much I appreciated what they were trying to do: Even if it was misguided."

"My own relationship with my dad was complicated," Soarin stated as he put a hoof around his superior. "Still, complicated as it was, there were times when I knew I was making him proud. And even when I wasn't, that just made the affection and praise I got from my mom all the sweeter," Then he licked his lips. "Speaking of sweeter, I think it's about time for me to help myself to that apple pie!"

"Indeed," Princess Celestia agreed. "A deal's a deal." And she teleported her charges back to the dining room so as to let them enjoy the apple pies they'd been promised.
