When Luna can't let something go, she decides she needs to get a little revenge on her sister.

Taking her sister's snide remarks to heart, Luna is dejected, frustrated, and most of all, angry. She feels a little revenge is in order. Nothing serious, just enough to show Celestia was real "foal's play" is.

And Eating It Too

Luna slammed her bedroom door, sending a thunderous clap throughout her room. Her anger not dispelled, she ripped it open again with a burst of magic before bashing it closed again and again and again.

Stopping just before she splintered the wooden door into a million pieces, Luna flopped onto her bed. She grabbed her pillow and pressed her face into it, letting loose a muffled scream of rage.

It was a solid minute before she came up for air, turning her head to the side as she huffed and pouted. “Stupid Celestia.”

What did she know anyway? “Oh Luna, the night can’t possibly be difficult to manage,” Luna reiterated her sister’s words, with a snobbish and nasally impersonation. “All you have to do is raise the moon and dream. That’s foal’s play compared to what I do.”

She kicked her hind legs furiously. Was that really all Celestia thought of her hard work? She wasn’t just talking about the changing of the lavenders every night; she worked her flank off patrolling every dream of every citizen of Equestria! And even Yakyakistan, now that their nations were on more friendly terms, come to think of it. It was exhausting work: battling nightmares, helping children overcome their fears, ensuring restful slumber for hundreds upon thousands of dreamers...

Luna pulled her pillow close to her body, squeezing it. “Foal’s play, huh?”

A thousand years ago, a fight like this had caused her to become Nightmare Moon. While Luna was nowhere near on the verge of something that angsty this time, she felt a similar sting of inferiority that she had all those years ago. If only there was a way to make Celestia value her night without getting banished to the moon this time around.

Suddenly, she sat up, an idea springing into her mind. Perhaps she could call upon something rather… nightmare-ish to make her sister respect her once again. Or at the very least, make her understand the importance of her dream walking duties.

She rubbed her hooves together, mischievously. A scheme took shape in her mind, one so harebrained that it actually made her giggle with giddiness. “I’ll show you foal’s play, dearest sister.”

In the ethereal realm between dreams, Luna paced back and forth anxiously. Before her stood tall, double doors. Intricate designs were carved into the gold material it was made out of. Flanking both sides were two marble columns.

It was the gateway to Celestia’s dreams, and it was just grandiose and decorated enough to make Luna hate it.

Of course, Celestia had such an elaborate dream door, one that she knew only Luna could see. It was like she kept rubbing it in Luna’s face how much better she fancied herself to be.

Luna squinted at the door, finally drawing her pacing to a close. “That should be long enough.”

Before falling asleep, Luna had cast a spell in the real world, one designed to morph the contents of Celestia’s room. It was effective but maddeningly slow. If Luna had been too impatient, her plan could have fallen apart in its second phase.

But now, she’d definitely given it long enough. By the time she got through with her sister in the dream-world, everything would be more than ready for her in reality.

“Phew,” Luna exhaled, shaking her shoulders to loosen them up. Her eagerness was making her too tense; she couldn’t have that getting in the way of her plan.

Finally, she turned the knob to Celestia’s stupidly designed dream door. As it opened to white light, Luna felt herself enter her sister’s dream. Goosebumps crawled along her legs, and her spine tingled as the sensation of dream walking washed over her. She’d felt this a million times before, but it had never made her so excited before.

As the light faded, Celestia’s dream took shape before Luna.

And it was just a bunch of cake.

Seriously. When Luna landed in the dream, her hooves sank into the ground. The white, creamy substance she stood on was obviously vanilla icing. Far her left and right, Luna saw massive strawberries, the size of mountains. Looking out, she saw more gigantic strawberries, dotting the horizon. They seemed to form a large ring around the frosting floor.

No doubt about it, Luna was standing on the top of a decorated, continental-sized cake.

“I’m beginning to understand why the phrase ‘Sweet Celestia’ is a thing,” Luna quipped.

Speaking of, Luna could tell her sister was nearby. The gluttonous sounds of someone scarfing down food was a dead giveaway.

Following the noise, Luna walked along the edge of Strawberry Mountain, leaving hoof prints on the frosting ground as she went. The chowing down sounds grew louder, and Luna finally caught up to her sister on the other side of the strawberry.

There was no other way to put it: Celestia was pigging out.

Luna almost did a double take when she saw it. Her sister stood amidst stacks and stacks of treats. She was surrounded on three sides by cakey towers, her back to Luna. The scores of junk food had every conceivable variation in them. Chocolate icing, strawberry icing, hot fudge sauce, sprinkles, no sprinkles, powdered sugar, chocolate chips, pound cake, coconut cake, coffee cake, cake cake cake.

Luna worried she would get diabetes just from looking at such a display. She almost wanted to turn away.

But she didn’t, because this was too perfect.

Celestia was so engrossed with her decadence, that there was no way she could focus on anything else. She dipped a slice of her current cake into the icing ground, and shoved it into her mouth, making euphoric moans as she chewed.

As… invested in the cake as Celestia was, there was no way she would notice changes in her environment. Not gradual ones, anyway. So long as Luna was careful, she would easily get what she wanted out of this.

Her horn buzzed alight, and the fabric of the dream began to distort.

“Such a messy eater,” she cooed. Celestia didn’t even look up or pause. Luna’s voice shouldn't even register to her right now. Rather, Luna spoke directly to Celestia’s subconscious, incepting an idea into it.

“Can’t afford to be so unclean,” Luna continued. Her magic warped a bib into existence, just below Celestia’s chin. Even from this angle, she could see her sister’s pristine white coat was already soiled with crumbs and icing, but that didn’t matter. So long as Celestia believed she needed to prevent a mess, it didn’t matter if one had already occurred.

The baby blue bib fastened itself to Celestia’s chest, strings looping around her neck and tying in place. Though Luna couldn’t see the front from here, she giggled prematurely at it anyway. She knew what was written on it: the phrase Pouty Poopy Princess, complete with a cartoon pony princess with stink lines above its diaper. Celestia didn’t even flinch at the sudden addition to her wardrobe. She barely acknowledged it.

“There we go,” Luna praised her sister’s accepting subconscious. “Hooray! Now you can eat even more cake!”

“MMMmmm!” Celestia happily chanted, mouth stuffed with half a cookie cake already.

Luna grinned wickedly. “What are you doing lying on the ground?” she cooed. “Princesses aren’t supposed to do that.”

Celestia actually paused as her mind relayed the question to her. She looked around at the frosting-coated floor in confusion.

“Have a seat, Princess” Luna suggested, a familiar chair ripped straight from the palace dining hall faded into view. As it appeared, Celestia leaned her body back, easing into it.

Luna was kind enough to levitate Celestia’s next cake to her so she wouldn’t need to reach for it. Her sister grabbed it gleefully, ready to begin her gorge session once more, but the cake slipped from her hooves and crumbled into her lap.

Luna had to snicker at her sister’s whimper in response. She was usually such a regal and stuck up pony. To see her so lax and carefree about her appearance was a rarity indeed.

“Oh no, that won’t do,” Luna said. “Let’s fix that, shall we?”

The armrests of the chair jutted out, morphing into a little table in front of Celestia as it pushed the ruined cake from her lap. The formation of the table pinned Celestia’s forelegs to her sides, but it seemed her sister didn’t mind. A new cake plopped down on the table, and she happily shoved her snout into it instead.

Luna laughed at the display of debauchery. Celestia was so engrossed in her cake that she didn’t even notice her seat slowly transform into a high chair.

Risking it a little, Luna went ahead and added baby blue booties to each of Celestia’s hooves to match her bib. They were all out of sight thanks to the table, and without a consistent sense of touch, Celestia didn’t even wiggle in protest as the fluffy garments encased her hooves.

“Uh oh,” Luna gasped. Celestia froze face deep into the cake. Her ears lowered as a sudden sense of worry reached her mind. “You don’t want to have to take breaks while you’re eating, right?”

Celestia shook her head, not thinking hard enough to question why she was hearing a disembodied voice.

Luna grinned, but with reservation. This would be the real test; failing to incept this idea could collapse the whole dream and ruin her plan.

“What if you need to go to the bathroom while you’re eating?” Luna inquired with a motherly tone.

Celestia crossed her legs, as though the thought hadn’t occurred to her. Her dream reacted to the distress, and an outhouse appeared about a dozen feet away from her.

“Oh, you don’t want that,” Luna cooed. “It’s so far away. And you can’t take your cake there.”

Celestia whimpered. Her dream lacked a fair deal of her usual critical thinking skills, existing mostly just to serve her own gluttonous desires. Luckily, Luna was here to help her out.

“I know,” she whispered softly. “What about…”

She let the thought go unfinished, as a thick, fluffy diaper appeared under Celestia’s rear end. Celestia kicked her legs, resisting. Even her subconscious could get embarrassed, it seemed.

“Now now,” Luna cooed, her voice motherly and soothing. “You want to eat your cake right?”

The kicking slowed.

“You don’t want to stop eating your scrumptious, delicious, mouth-watering cakey-wakey, do you?”

Celestia’s legs lowered, relaxing. The diaper wrapped around her waist, taping itself snuggly in place. She’d accepted.

“YES!” Luna cheered, hoof pumping the air. She’d done it! She’d all but won at this point.

Now… now she just had to let the dream play out a little. Then the real fun could begin.

“Good job, Celestia,” she murmured. “You enjoy your cake now, you hear? Eat as much as you want… because you deserve this.”

Thank goodness no one can see me right now. That thought had been running through Celestia’s mind for what felt like hours.

She ripped into the next treat before her, a chocolate cake with chocolate icing and chocolate sprinkles. Nothing too wild, but delicious nonetheless. Her head dipped back down for another bite before she’d even finished swallowing her first. And another. And another.

This was never something she could get away with in the waking world. A Princess couldn’t afford to stuff her face so… thoroughly. Not even just because of how many pounds she would pack on, too. It was simply a matter of keeping her image intact. If the general public saw her doing something like this then, well, it would be outright shameful.

But it was still disappointing that the sweet, sweet taste of chocolate that swarmed her mouth right now was nothing but a figment of her imagination. Not that she really cared; cake was cake, and that was all she needed to enjoy it.

As she polished off the last of the triple threat of chocolate, Celestia finally came up for air.

Aside from the pile of crumbs that sat below her chair, her surroundings were bare. The stacks upon stacks of cakes she’d summoned had all been devoured. She licked her lips, satisfied at the monumental task she’d overcome.

And I didn’t even need to use the bathroom once, she thought cockily.

Wait… why would she need to use the bathroom? This was a dream, right?

Celestia blinked out of curiosity. That’s right. But then why…?

Why in Equestria had she believed she might’ve had too?

She shifted in her seat, feeling the soft hug of a diaper around her waist. She’d let that be put on her… but why?

Suddenly, her cheeks flushed red. Wait, I’m wearing a diaper? The full ramifications of what that meant suddenly struck her. For some reason, she hadn’t allowed it to click that wearing a diaper and not fearing bathroom breaks meant she’d been prepared to…

“Uuugh!” Celestia cried. She kicked her hind legs, struggling in her seat. The table of her highchair kept her pinned down, however. She couldn’t even raise her forelegs up thanks to it.

“Wait…” Celestia wondered allowed. “Why am I in a highchair?”

Now that she was really thinking about it… what had she been thinking? A diaper? A highchair? A bib?

A bib? Celestia looked down at her chest. Sure enough, in place of her usual regalia there was a baby blue bib wrapped around her neck.

“Why am I wearing a bib?!” she cried out. How had this been allowed to happen? Just because she’d been lost in a cake-eating induced trance didn’t explain it. There’s no way she would have dreamed these things to happen to her, right?

The more and more lucid Celestia became, the more and more confused she got. What had she been getting up to? Why would so many foalish things happen to her in her own dream? Why couldn't she get out of any of it?

That was the most concerning part. Despite coming into awareness of her dream, Celestia found she could still not escape the highchair. Her hind legs kicked higher, and she caught sight of booties on her hooves.

Booties?

“This is ridiculous!” she cried. There was no way this could be happening.

After a sustained flurry of kicks and diaper crinkles, she stopped her struggle. Grunting in frustration, she leaned her back against the high chair, breathing heavily.

“Okay… okay…” she exhaled. “This is still just a dream, no matter how many weird things are happening. All I’ve got to do is wake up. Just wake up…” She closed her eyes, cutting off the bizarre cake world she’d created and focused her mind to stir some activity. “Just waaaake up…”

Slowly, she could feel herself drifting. Keeping her eyes sealed, Celestia remained focused on her one and only goal: waking up and escaping this freaky, padded nightmare. Faintly, she thought she heard laughter, but it was easily ignored. She was completely and utterly focused on getting back to her room, her bed, her regular clothes.

Just...

Wake… ...

Up… … …

She opened her eyes.

Celestia was lying down now. It was a promising start, much better than sitting in a high chair. She saw the familiar sight of her ceiling and sighed with relief. She was awake.

She started to sit up, only to freeze. Cushiony padding pressed against her rear and rubbed her inner thighs. Her hooves felt surrounded by soft, silky fabric, and she could feel a similar presence against her chest. Startled, she looked down.

Bib. Booties. Diaper.

Nothing had changed. With a groan, Celestia realized she was still dreaming. A look around only confirmed her suspicions.

What she had thought was her room actually only barely resembled it. Instead of her bed, Celestia was lying down in a giant crib, pink bars stretching up and way over her head. Her nightstand was now a changing table, where her dresser used to be was a giant playpen, with blocks and rattles scattered about within. Her royal blue carpet was now an assaulting shade of magenta, and her walls sported cutesy wallpaper dotted with red, pink, and white hearts.

It may have been the general layout, but there was no way this was her room.

Celestia groaned, hooves to her head. It couldn’t even hide the sea of red the flooded her face.

Honestly, what is going on with this dream? I feel as if I don’t even have control. But she was completely lucid! Being aware this was a dream should give her at least some modicum of control, right? So then why did it feel like somepony else was pulling the strings here?

Click.

Celestia’s ears flicked. Looking up, she saw the door to her nursery-room opening.

Luna strolled into her sister’s room with a confident swagger and a smirk wider than the sun. She hummed a catchy tune as she shut the door behind her, relishing the look of utter terror on Celestia’s face.

As recognition took hold, that terror quickly morphed into bright pink humiliation, followed up with a scowl of annoyance. “Luna!”

She laughed. “Hello there, my big sister. Or… is that my baby sister now?”

Understanding quickly dawned on Celestia’s face, and her blush subsided slightly. “Ah, now I see. So you’re the one responsible for making my dreams into…” she gestured to the nursery at large. “...this.”

Try as she might, Luna could not stop a mischievous grin from crawling up her cheeks. Yes, just your dreams. She giggled. “Yes, well, I suppose I’ve been found out now, haven’t I?”

She could barely contain her laughter. Any second now, Celestia would explode with anger. A temper tantrum, whining, perhaps even crying… she could see it all now. Her sister may act big, but now Luna was going to prove she was nothing more than a bratty little foal deep down.

“Oh, Luna.” Celestia tsked at her, a sickeningly disappointed tone dripping from her voice. “Is this about what I told you earlier?”

Luna’s jaw slowly opened, but no sound came out. Her eyelids pinched upwards in confusion, and worry.

Really?

Not even a whimper? Not even one modicum of embarrassment? The blush on Celetia’s cheeks had all but faded now. As the white alicorn sat up in her crib, she didn’t even try to use her magic to escape her predicament. (Not that it would matter, given the inhibitor ring surreptitiously slipped on her horn.)

“I’m afraid you’ve only proved my point, dear sister.” Celestia smirked, as if she was winning. “If you have time for a childish prank such as this, your duty of guarding dreams simply can’t be as difficult as you make it out to be.”

Oh my stars… is she actually… Luna’s blood boiled. Her concern gave way to frustration. “Are you serious?”

“Quite,” Celestia gloated from her crib. “Or were you honestly expecting such childish antics to prove a point?”

Luna clenched her jaw hard enough to shatter diamonds. This hadn’t been enough? Celestia wasn’t going to let being stuck in a diaper or a crib get to her in the least? Couldn’t she see she was supposed to be humiliated right now? This wasn’t enough to make Celestia understand not to treat her so… so expendibly?

Luna tensed up, feeling her seething anger compound. A litany of taunts and insults were on the tip of her tongue, but she had to bite them back. Celestia was reclining against the bars of her crib, and almost expectant smile on her face.

This was no good. Now Luna was on the verge of being the one to throw a hissy fit. She’d never prove anything to Celestia at this rate.

I… I can work with this, Luna through, slowly. I still have my trump card, after all.

She cleared her throat, taking the chance to push down her feelings. Wryly she said, “I just wanted you to know what real foal’s play was like, that’s all.”

“Honestly?” Celestia put her hooves behind her head as she got comfortable in her crib. “It’s still probably more work than you have to do.”

Luna saw red. “O-Oh yeah?” she challenged, barely keeping her cool. If she thinks getting under my skin will be enough to stop me, she’s got another thing coming.

Right now, Celestia was confident, and that was all. Luna knew she believed herself to still be in a dream, which was perfect. So long as she felt like nothing held much consequence, she wouldn’t put up a fight. In fact, if Luna played things right, she might just have a willing victim on her hooves.

“Then what do you have to say about…” she charged up her horn, a spell blinding the room. “This?!”

When the light faded, a pale blue pacifier was sticking out of Celestia’s mouth. Her eyes widened with momentary surprise, but her mouth seemed to grow familiar with the rubbery presence. She gave it a suckle of curiosity, and then chuckled.

“Oh no,” Celestia feigned with atrocious acting skills. “Dere’s a pacifiwer in mah mouth. Wha’ eva shaww I do? I simpwy mus’ admit dat you hab da hawder job now.”

She spat the pacifier out onto the crib bed, and raised her eyebrow at Luna. “Satisfied?”

Luna rolled her tongue in her mouth; she had to carefully select her next few words. “What, the almighty Celestia is too afraid to suckle on a wittle pacifier? I thought this was supposed to be on par with what I do every day. Are you saying you can’t handle it?”

Celestia’s raised brow lowered into a furrow. “I see what you’re trying to do Luna.”

Luna forced an innocent smile on her face. Oh, do you now?

Despite supposedly seeing through it, Celestia still took the bait. Her hoof reached down for the pacifier. The bootie caused her to awkwardly fumble with it, but eventually she managed to shove it back in her mouth. “Bu’ fine. If woo weally tink woo can pwove a poin’ wiff dis, go wight ahead an’ twy.”

Yes! She got her. Celestia wouldn’t back down now; not as confident as she was now. Luna was willing to bet Celestia felt she could handle anything her ‘dream’ could through at her in exchange for gloating rights the next morning. So long as she didn’t give up before Luna, then the argument was hers. And why would she need too? Considering none of this was real or anything. She might even try playing along just to show Luna how futile this all was.

Let’s see how above it all you are after this, Luna snickered to herself. “Well, well, well, look who’s being such a good filly now.”

Celestia rolled her eyes, giving the pacifier an obligatory suckle. “Yeah, yeah.”

“Well, behaving or not, you still have a job to do, Miss Princess.” Luna cast a new spell, teleporting a large stroller right in front of her. Another flash, and a single-strapped, black bag appeared around her. She gave it a pat, smiling as she felt the prepared supplies inside.

Celestia didn’t even flinch at the sight of the stroller, let alone blush. In fact, went so far as to fake a yawn at the sight. “O’tay, Wuna. Wha’eva woo wanna do.”

Just a little longer. Luna forced herself to think as she pushed the stroll by the crib. You won’t have that attitude in just a bit, dear sister.

She levitated Celestia up and out of the crib, and set her back down into the stroller. Her telekinesis snapped the straps of the stroller over Celestia’s body, making sure to pin her fore legs down by her sides. Celestia gave a cursory push against the straps as they buckled, but they didn’t so much as let her bend her legs.

Luna knelt down to be eye level with her sister, and gave her a boop on the nose while grinning madly. Celestia rolled her eyes, unimpressed.

“Now then,” Luna whipped the stroller around with her magic, grabbing the front. Celestia grunted at the sudden shift but stayed in place. “Let’s get you ready for Day Court, shall we?”

“Hmmpf.”

Luna pushed the stroller forward, aiming for the door as her telekinesis flicked it open.

Two guards always stood on guard outside of Celestia’s room, and today they were the lucky first ponies to witness the filly-fication of their ruler.

Heads turned as Celestia was wheeled out of her room. Luna hummed the same catchy tune she had when she entered, not minding that she flew completely under the radar. All the guards attention was right where it needed to be.

Their pupils shrank, eyebrows nearly leaping off their foreheads as Princess Celestia passed them by in all her diapered glory.

“Oh come now, Tia,” Luna cooed. “At least say hi to the nice guards.”

“Hewwo,” came Celestia’s unenthused response. Luna had hoped her sister would at least let a little embarrassment slip out here, but considering how convinced she was that this was a dream...

“Sorry,” Luna winked to the guards. “She’s being such a bratty little foal this morning.”

They pushed on, not lingering with the guards long.

As they made their way down the hall, Luna angled Celestia away from the windows as best she could. The moon had been lowered, but the with the Princess of the Sun a little preoccupied right now the morning was stuck in a perpetual dawn. She certainly didn’t need Celestia to catch on to that.

Luckily the curtains were drawn just enough to kind of hide it, but Luna still tugged the bright pink canopy of the stroller down, obscuring Celestia’s peripherals.

Now all her sister could focus on was the waves of castle staff before her. Guards changing out for the morning shift, maids lugging cleaning supplies around, the odd assistant rushing to find a cup of coffee before starting the day.

All stopped and stared when Celestia came their way.

Luna slowed their pace to a crawl, ensuring everyone they ran into got as long as possible to drink in Celestia’s appearance. None spoke up about it, though hushed whispers chased Luna’s ears when they finally moved on.

“Seems your new look is quite the attention grabber,” Luna remarked. Celestia grunted in return.

Luna had no doubt her sister was struggling not to be embarrassed by now. No matter how sure of herself she was that none of this was real, it was still quite a feat to survive so many prying eyes without a single blush.

As they made their way to the throne room, a new noise drew Luna’s attention: the rumbling of an empty stomach.

Right on schedule. “Aww, is wittle Celly hungry? And after pigging out on all that cakey-wakey, too.”

There was a rustling as Celestia shifted about, no doubt a touch uncomfortable. “Stop it,” she accused.

“Don’t worry.” Luna stopped pushing, walking around to the stroller’s front as her magic dipped into her shoulder bag. “I’ve got just the thing for you.”

She withdrew a baby bottle, filled to near bursting with warm formula. Luna popped the pacifier from Celestia’s lips, and offered the amber nipple to her instead.

“Really?” Celestia pressed her lips together. Even she couldn’t hide the faintest twinge of pink on her cheeks, however.

“Oh, is that a blush I see?” Luna asked, nudging the bottle forward a tad. “Don’t tell me you can’t handle this of all things.”

“Why, it’ll be a simple as raising the moon always was,” Celestia quipped. She parted her lips and Luna slid the rubber nipple between them.

She waited just a moment, making sure her sister actually started suckling before returning to the back of the stroller. Her hoof just barely covered her mouth in time to stifle a laugh. If Celestia knew what was really in that bottle, she wouldn’t be drinking it down so greedily.

They resumed their stroll of shame. With cutesy suckling sounds now come from the stroller, Luna didn’t feel the need to hum over the silence. Even more aghast looks were thrown Celestia’s way now, and Luna sincerely hoped her sister was committing each one to heart.

She was having so much fun, that she decided to take the scenic path to the throne room. Making a point of it, Luna rolled her sister past every patrol route she knew, encountering at least half of the castle’s guards on the way.

Once she felt she’d given Celestia ample time to finish her breakfast, she finally guided them to the throne room.

She came to rest just on the outside of the tall, looming doors and maneuvered to the front of the stroller once again. She could hear confused murmurs just barely eking through the thick doors. The ponies inside were getting antsy.

She saw Celestia was holding the now empty bottle in her mouth. Her sister averted her gaze when she saw Luna’s face, but seemed to remember she shouldn’t show any embarrassment and rushed to stare her down.

“Not so hungry anymore?” Luna asked. She plucked the bottle from Celestia’s lips.

“Had enough fun yet?” Celestia dryly replied.

“Aww, what’s the matter? Can’t take it anymore?” Luna smirked. “Cause you’d never survive my job if foal’s play like this is too much for you.”

“Sure, sure,” Celestia rolled her doubtful eyes as the pacifier found her mouth again. “Awwow me to show woo wha’ a weal day of wowk wooks wike. Assuming woo couwd even make a dweam out of it, dat iz.”

“I think you’ll find it to be fairly… accurate,” Luna snickered. “Here, let’s get you too your throne.”

She fluttered behind the stroller once more, excitedly pushing the doors to the throne room open as she began to wheel Celestia inside.

Celestia simply suckled on her pacifier as Luna pushed her inside the throne room. She wasn’t going to give Luna the satisfaction of having this get to her, after all.

Heads turned as Celestia’s ride into the room began. Ponies eager to meet with her had all crowded inside already, and had been eagerly awaiting her arrival. Commonfolk and nobles alike were ready to see Princess Celestia’s regal entrance. Which it was why it was no surprise when they were all surprised.

So many jaws hit the floor that it felt like a mini-earthquake. Ponies stood frozen at the sight, so much so that they almost forgot to part the crowd and let her through. The few that did shuffle out of her way were no less shocked than the rest, they just probably didn’t want to get too close.

Luna wheeled her forward as space was made, but at a snail’s pace. Celestia practically groaned as she did, impatient to just get this over with.

In fairness, Luna had conjured up a pretty accurate depiction of her morning. The throne room was no less packed than it usually was on a busy day, which was every day, come to think of it. Though a few out of the ordinary touches had been added.

Celestia looked past the figment ponies and up at the stain glass windows as they rolled. In an impressive attention to detail, Luna had systematically replaced all of Celestia’s immortalized feats with new depictions. There was one were Celestia was stacking blocks in a playpen, one in which she was relaxing in a baby bouncer, one where she seemed to be throwing a rattle around in a tantrum, and even one of her at what appeared to be a Summer Sun Celebration. Only in it, she wasn’t raising the sun, but instead her plot, for a feat she didn’t have to speculate about.

All of which, of course, had her decked out in her current attire of a bib, booties, and painfully large diaper.

Cute, Luna. Celestia still didn’t get what this was supposed to accomplish. Maybe Luna was just enjoying her time on top, despite Celestia consent. Who knew, if this dream would get her sister to stop prattling on about how tough and exhausting her job of sleeping was, then it would be worth it in the end.

The last of the ponies finally parted, as bug-eyed and horrified as the rest, and their journey finally concluded.

But Celestia was not rewarded with the shining sight of her usual golden throne. No, that was gone. And in its place sat Luna’s next little alteration: a pink, plastic training potty.

Ugh. At this point, Celestia was just annoyed. Her grumpy demeanor was not helped by the fact that she’d begun to feel a sharp pain in her stomach, too. She chalked that up to Luna’s doing as well, certain her sister was twisting this dream in as many ways as possible to get on her nerves.

The straps unbuckled thanks to Luna’s telekinesis, finally freeing Celestia’s forelegs. She left the stroller, standing up for the first time in what felt like forever. Never mind all the ponies she just gave a great view of her padded plot, they didn’t matter anyway.

“Well, go up to your ‘throne’, little filly,” Luna mocked. “Show me how tough your day always is.”

“Hmmph.” Celestia suckled on her pacifier as she approached the scaled up training potty. As if. Why should I work my flank off for nothing but a dream?

“Sorry everypony, I know Princess Celestia is rather late today,” Luna said, addressing the crowd. “She’s been such a cranky foal lately. I’m sure you all understand.”

“I naw cranky,” Celestia snapped back at her, annoyance reaching a tipping point.

Murmurs of discontent rippled through the crowd, but nopony spoke up. Celestia turned around and awkwardly tried to position her plot over the bowl of the training potty. She lowered herself, needing to sink far further than usual just to sit. Her diaper crinkled noisily as it touched the potty, pushing against her pelvis as she sank deeper into it.

Finally. “We wiww now howd Day Couwt,” Celestia called out through her paci. “Stewp fowwawd wiff any biffness.”

Silence.

Heads looked back and forth, hooves shuffled. Nopony wanted to be the first to address the filly princess, it seemed.

While waiting, Celestia stomach gurgled, the pain becoming more acute as it now shifted a little lower. Of all things, that was the most uncomfortable thing about her situation. The vacant gazes of dream ponies she could get used to, and the diapers and booties were at least soft. But whatever Luna was doing to her stomach was just plain aggravating.

Finally, Fancy Pants stepped forward and cleared his throat. “Ahem, Princess? Do you really think it’s appropriate for you to be holding court dressed like… well, that?”

Celestia rolled her eyes. Somehow, Luna had nailed his snobbish voice perfectly. “Shuddup,” she barked at him.

Fancy Pants blinked in shock. “I beg your pardon?”

Off to the side, Luna snickered to herself, only making Celestia narrow her eyes. “Woo heard me, shuddup. Go be stupid somewhere ewse.”

Fancy Pants gasped. “My word!”

A yellow unicorn mare, Upper Crust, came to his defense. “Your Majesty, with all due respect, do you honestly believe you’re in a position to refer to others as stupid?”

Her stomach gurgled again. Celestia winced; Luna was definitely playing up the annoying side of the crowds. The nobles were usually the worst.

“I can tawk any way I wanna,” she declared, glaring down Upper Crust.

“Maybe she needs a time out,” came a tentative quip from somewhere in the crowd. Nervous laughter rippled across the room.

Celestia actually blushed to that. She knew she shouldn’t let the figments of this dream get to her, but she hadn’t expected back talk.

“Be quiet!” she pouted, kicking her hind legs against the sides of her plastic training potty. It only served to fuel the rising chuckles.

Celestia frowned, biting down hard on her pacifier. Her stomach gurgled again, a pressure now mounting in her bowels. Realization at what Luna was trying to make her do finally struck her.

This is stupid. This whole thing is just stupid.

“Princess,” Fleur de Lis hesitantly stepped forward. “Please stop this ridiculous display. You need to do your duty.”

Celestia’s eyelid twitched, her bowels rumbling. She’d had just about enough of this whole stupid dream debacle. But at least it gave her a chance to show all these nobles exactly what she thought of them.

“Woo wanna see me do my duty?” She stood, kicking the plastic training potty away. “Fine.”

She turned, raising her plot into the air and hiking up her tail. With a grunt, she forced the pressure in her bowels out.

There were mortified gasps and screams. Some ponies swooned and fainted. Luna cackled.

Princess Celestia filled her diaper before the royal court.

She shuddered as a slimy mess burst free and hit her padding. The diaper was thick, but still had to sag to compensate. As Celestia dumped her hot, steaming load into it, she grunted and moaned, suckling her pacifier for all it was worth.

The rancid smell permeated the air, chasing away the few ponies who hadn’t already been scared off. A few dragged off their unconscious friends in a valiant effort to leave none behind to face the Princess’ dirty behind.

When it was over, she gasped, not realizing how she’d been holding in her breath the whole time. A blush rested on her cheeks, despite her best efforts, but she supposed it was fine. The stinky mass in her backside had no doubt stained her other cheeks a different, far worse color. But hey, at least she’d lived up to the label on her bib.

Luna clapped off to the side, face racked with an ear-splitting grin that almost seemed painful. “Well, it looks like you managed to clear out the Day Court in no time, sister,” Luna snickered. “And here I thought your job was supposed to be hard.”

“Yes, yes, woo’ve had wour fun, Wuna,” Celestia spat out the pacifier. A chill ran down her spine at the sensation of the sticky mess coating her undercarriage. “If you’re satisfied, then how about you allow me to wake up now. Some of us actually have to work come morning.”

Somehow that ear-splitting grin grew wider. “Wake up? Oh sister, you must be confused.”

Those words made Celestia’s heart stop. “What?”

Luna looked high as a kite. “Don’t you remember? You already woke up. Back in your room.”

“...No...”

Luna’s magic withdrew a new diaper from her bag. “Now now, don’t be such a cranky filly. Here, I’ll get you a nice changie-wangie, how does that sound?”

Celestia doubted her face had ever been paler in her entire life. A cold, burning rage filled her, but she was too stunned for it to go anywhere. Luna gleefully trotted up to her, diaper teasing her as it wiggled in the air.

Leaning in, Luna whispered into her ear. “If it’s any consolation, I’ll admit your job is going to be much harder than mine from here on out.”

Celestia pressed her hind legs together with worry, inadvertently squishing around the mess in her diaper.

All of the new stain glass windows shattered from what came next. Celestia’s shout thundered across the entire nation of Equestria, decimating eardrums and sending Pegasi falling from the sky.

“LUUUUUUUUUNNNNAAAAAAAA!”

Meanwhile, all the way over in quiet Ponyville, hundreds of citizens were torn from their slumber by a shout many would later assume was a dragon’s call and start a panic over. Though, when the news of what had gone down in the Princess’ throne room earlier that day hit the papers, the whole thing suddenly made a lot more sense to them all.

Extra! Extra!
