Starlight's Padded Princesses
Starlight sighed as she leaned over the arm of her new shiny throne, resting her chin on one hoof while gazing down the length of the impressive hall in front of it. She lazily eyed the many large stain glass windows built into the walls. Most had already been replaced at this point, though some stragglers still remained. At the other end of the long chamber, two guards stood at attention by the large doors with wide happy smiles constantly stretched across their muzzles. A set of equal sign cutie marks adorned their flanks, peeking out slightly underneath their armor.
She'd finally done it. She’d won.
At first, Starlight hadn't been too sure Starswirl's spell would actually work, especially not as well as it had. But in the end, her plan was just what she needed to finally rid Equestria of 'Princess Twilight' and the rest of her meddlesome friends. Even now Starlight hadn't decided on what to do with them now. With time re-written, they likely had no idea that they used to be such irritating thorns in her side...
An irritated grumble lured Starlight's gaze down where she chuckled at the two ex-princesses of Equestria chained to the base of the marble throne. Luna glared back at her, a defiant look in her eyes, whereas her sister refused to so much as look up from the smooth marble floor beneath her hooves. Mane cast down over her eyes, the alicorn had remained mostly silent since the takeover. The two princesses’ once-famous cutie marks had been replaced as well, and their manes no longer flowed with the same majestic elegance they once did.
The two had put up quite the fight, though while they certainly used to have more magic power than Starlight herself, the wave of revolution that swept over Equestria was far more powerful than either of them could ever hope to become. There would be no help from up north either. A recently returned King Sombra had been seeing to that.
Unfortunately for Celestia and her rebellious little sister, Starlight couldn't just let the two alicorns wander the streets of Equestria with the rest of the nation’s broadly smiling populace. Equality was a fragile luxury and she refused to let even the sight of the old rulers cast doubt into the minds of her new citizens. Unfortunately, neither had yet to fully submit, and it didn't seem like they would be any time soon. At their current rate, Tartarus was looking to be the safest option...
That said... there was one thing she wanted to do with them...
Celestia remained silent as she was led along in chains through the long empty halls she herself used to freely roam. Double Diamond, Starlight Glimmer's second in command, was leading her and Luna towards the dictator’s quarters. There was no telling what deranged ideas the mare had planned for them this time.
Celestia could still remember the horrible sight of a massive army of her own citizens marching on Canterlot, demanding that they step down and be replaced by the one unicorn behind their movement. If it had merely been a lone power-hungry villain, then perhaps they could have fought back, but not against so many misguided, and ultimately innocent, ponies. Though she’d held the power to control the heavens themselves, once her ponies had been turned on her, she had nothing.
"Alright you two, we're here!" Double Diamond suddenly announced with his usual unrestrained enthusiasm, contrasting starkly with the depressing aura that surrounded the two alicorns behind him.
The door to Starlight's quarters, Celestia’s old room, opened after Double Diamond's proud declaration, revealing the purple tyrant standing on the other side. She looked down at the two princesses with a sinister smirk before looking up and speaking to her right-hoof stallion.
"Thank you, Double Diamond. That’ll be all for now. I believe I have finally found one last technique that will finally show these two 'free-thinkers' the error of their ways." She explained to the brainwashed stallion, who looked downright elated at this wonderful news.
"Yes mam! I can't wait to welcome two brand new friends to our proud nation!" He replied with a cheery grin, raising his hoof to salute before trotting back the way they’d come.
Celestia cast a sideways glance over at her sister as they both shared an anxious look. Just what did Starlight have in store for them this time? They weren’t given long to ponder this, however, as a moment later they were both yanked forcefully into the room by their collars. With a flick of her horn, Starlight slammed the door shut behind them.
With a confused scowl, Celestia and Luna turned to face the mare, only to be met with a blinding flash of light...
Luna's eyelids felt heavy as they slowly fluttered open. Shaking her head, she tried to clear her jumbled and cloudy mind as she felt the familiar floor of the throneroom beneath her hooves once again.
'W-what happened?' She thought, trying to piece together her memories.
The last thing she could remember was being dragged into Starlight's room with her sister... and then everything after that was blank. Had the mare done something to them?! Or perhaps it was all just a strange dream?
Looking up as her vision cleared, Luna found that she was indeed back in the throne room, still sitting at the foot of the throne with a collar tightly secured around her neck. Looking over for her sister, Luna gasped. Completely befuddled, she stared at Celestia, her eyes trained on a very peculiar object that now adorned her flanks. Was she wearing a... diaper?
Luna almost didn't believe what she was seeing until Celestia turned and met her sister's baffled look. A subtle blush rose on the other alicorn's cheeks as she glanced back anxiously at her newly padded posterior. Shifting on her hooves, the diaper crinkled.
"S-sister?! What has happened to you? W-why in Equestria are you-" Luna started to say as she stood up, only to pause mid-sentence as she heard more crinkling and felt something soft and tight wrapped around her hips.
She was wearing one too. Incredibly confused, and understandably embarrassed, she turned to glare up at the throne where Starlight was indeed watching them with a look of amusement.
"W-what have you done to us?! W-why have you put these... these t-things on our flanks!?" Luna demanded, certain that this had to be some kind of trick.
Celestia remained silent as she found herself instead staring back at her sister's padded rear. Starlight didn't immediately reply to Luna’s question, merely chuckling to herself as if laughing at an inside joke.
"Hmm, you know, I think it's about time I took the two of you on a tour of the new and improved Canterlot." Starlight abruptly stated, disregarding Luna's demands for information as she stood up and took ahold of their chains with her magic. "Now come along, I believe it's about time that your little ponies saw what has become of their previous rulers~."
Dragged to her hooves by the chain around her neck, they were forced to follow the mare towards the exit. Meanwhile, Luna continued to pelt the unicorn with questions to no avail. All the while, she remained unaware of the strange looks Celestia had been giving the new padding wrapped around her flanks. There was just something about seeing Luna wearing a diaper that was... strangely alluring...
Luna's face burned with embarrassment as she stared down at the road beneath her hooves. She refused to meet the curious eyes of the many ponies that filled the street around them. With an awkward gait to each of her steps, she cringed at the loud crinkling that constantly arose from her diaper. Celestia waddled alongside her in a similar manner, though her blush wasn’t quite as prominent.
Starlight trotted along just ahead of them, parading the two padded alicorns through the busiest city streets of downtown Canterlot. With whispers and hushed gasps, ponies watched them go by, with hardly a single one crossing their path that didn't at least turn to look at the diapered princesses.
‘Is this really all she wants? Is Starlight really just trying to destroy our public image by... making us wear diapers?!’ Luna thought to herself, gritting her teeth.
"Hmm... you know, I'm feeling a bit peckish I think. How about I show you two how the dining district is fairing, hmm?" Starlight offered with an innocent smile, abruptly changing direction as they were both yanked down through another street.
But before they could get very far, a curious little filly from the growing crowd approached Starlight with a nervous look on her face. Hesitating for a moment before opening her mouth, she asked the question that just about everypony was thinking.
"Um, Miss Starlight Glimmer? Why are those two wearing diapers?"
"Hm? Oh, hello there little one~. Well you see, its simply because they’ve always worn them!" Starlight replied, reaching down to pat the little filly’s head. "I'm afraid to admit it, but these two, for as powerful as they claimed to be, were lacking in even the most rudimentary of toilet training. They’d been hiding it from you all for generations, but without their powers, they are no longer to hide the truth of their weakness."
"W-what?!" Luna suddenly roared, utterly outraged at the very notion of what Starlight was trying to suggest. "We have no such-"
"Now now, little Lulu~.” Starlight quickly interrupted, raising her voice sharply. “You know what happens when you get fussy with me like that. Sometimes, you just can’t help but end up making a big mess."
"S-silence, tyrant! You will not talk to us like we are some l-little- g-guah?!" Luna suddenly gasped as she began to fumble her words, her right hoof still outstretched in an accusatory fashion towards Starlight as her pupils shrunk.
*Prrrraaapfpt~!* *Crackle~*
An intense blush erupted onto the alicorn’s face as what felt like a literal avalanche of semi-solid waste rushed out into the seat of her diaper. All around there were gasps of shock from the crowd as they witnessed the back of Luna's diaper rapidly expand. Wet crackles from within the bulging padding dominated the silence that followed as it soon reached maximum capacity.
By the time it was all over, a nearly watermelon-sized lump hung down from the seat of Luna’s diaper, sagging just a few inches over the street. The tough fabric turned a murky brown color, ensuring that everypony watching knew exactly what had just happened. Having stepped back in shock as the spectacle started, Celestia held a hoof over her mouth as she witnessed the last of her sister’s bowels empty into her diaper. Heart pounding in her chest, she couldn't help but find herself completely entranced by the incredible mess.
"Uh oh, it looks like somepony has had an accident~.” Starlight cooed before grinning smugly. “I told you not to get all fussy with me, missy." Starlight scolded, turning to face the many disgusted ponies in the crowd who’d already reached up to shield their nostrils. “I’m terribly sorry that you all had to see that everypony, please excuse us.”
Luna’s hoof finally landed back onto the ground as any and all words in her throat had died, leaving her eyes wide and her cheeks flushed red like a ripe tomato. Her brain struggled to even comprehend what had just happened. It was as if she hadn’t even been in control of her own body. But even as hot embarrassment dominated, she couldn't ignore the immense feeling of relief that was quickly overtaking it. It was as if she’d been holding it in for weeks, only to finally clear out her entire system in one fell swoop.
“Oh well, I suppose I’ll just have to get you changed when we get back home, hm?” Starlight giggled, admiring the conflicted look on the night princess’s face. “I’m afraid nopony will want us eating in their restaurant after that, but I still have one other place for us to visit before we head back.”
Yanking the two of them forward again, Starlight weaved them through the stunned crowd, many of which were finally beginning to disperse once they were caught downwind of Luna’s immense load. Forced to waddle due to the padding’s inflated girth, she half gasped as the contents of her diaper sloshed and squelched into every nook and cranny against her and spread across her flanks...
“Ah, here we are then.” Starlight sighed, gazing up at the front of a rather peculiar looking store. Adult diapers and various other items of a similar nature were hanging in the front windows.
Celestia managed to tear her eyes away from the bloated seat of her sister’s soiled diaper at the unicorn’s announcement, blushing as she realized what she’d been doing. For the life of her, she hadn’t been able to keep herself away from Luna’s messy diaper for longer than a minute. The sight alone, much less the noxious smell should’ve disgusted her... but it didn’t... not even a little bit.
A small portion of the crowd from earlier was still following them through the city, though their eyes almost never left the seat of Celestia’s padded behind. After Luna’s sudden accident, they almost seemed eager to find out if she’d end up doing the same. However, at least for the moment, her diaper had remained clean. Though after what Celestia witnessed, that could apparently change in a matter of moments.
Luna herself had not said a word since filling her own diaper. Even now she kept her head low in front of her, with both wings doing their best to shield her face from the public eye. Celestia could practically feel the heat coming off her face from where she stood.
“Well, lets head on in, hm? I’ll especially be needing more diapers after what Luna- Oops!” Starlight yelped, having narrowly stepped right into a small puddle of water gathered amongst the cobblestones in the road.
Yet, as she looked up from it, a sinister grin spread across her muzzle. Stepping gently around it, she gestured for the two of them to do the same, locking her gaze primarily at Celestia.
“Careful you two. You definitely don’t want in and get... wet, right?”
Celestia was a little confused as to why Starlight was making such a big deal out of a mere puddle. In fact, with the way she was speaking, it was almost as if-
*Hissssss*
But then, before the princess could complete that thought, a faint muffled hissing sound filled the air. As it slowly grew more audible, Luna’s head shot up from where she’d been hiding in her own mane. Glancing back at her own diaper fearfully, she was puzzled to find it still merely bloated with poop. However, it then became apparent that it was, in fact, not her own diaper that was now being flooded.
A sharp gasp from Celestia confirmed it as the alicorn slightly lifted one of her hind legs and peered down beneath her barrel to watch as the underside of her diaper started to sag and turn yellow. A few exciting murmurs could be heard from the other ponies watch as they too picked up on what was happening. Soon the blood rushing to her face matched that of her sister as Celestia continued to uncontrollably soak her diaper.
“Oh my, It seems that Luna wasn’t the only one who needed to go potty~.”
Starlight chuckled quietly to herself as she noticed a scrawny stallion mostly hidden in the crowd, snapping several photos of the scandalous scene before him. No doubt the next issues of the national newspaper would be spreading like wildfire all across the country, telling the tragic and embarrassing story about Equestria’s old rulers and their secret.
“Make that at least two packs of diapers I’ll need to buy for you two then. I’m going to need a bunch at this rate~...”
As they finally made it back to the castle, Luna’s and Celestia’s diapers had both swollen dramatically. Though, Celestia had yet to actually mess herself. Packed with a second even bigger load of pony manure than before, Luna’s diaper was twice the size it had been at the store. The alicorn seemed to tremble with every broad step she took, however, all signs of embarrassment were strangely no longer present. Instead, it had been gradually replaced with an emotion that Starlight had not anticipated seeing... arousal.
As she led the two sisters back towards the throne room, Starlight no longer looked quite as smug as did before. Turning back to the two mares with pinched eyebrows, she couldn’t help but be a bit confused. At the very least, her plan to humiliate the pair had gone pretty much perfectly. Even the trigger words she’d enchanted their minds with had so far worked exactly as intended. However, there seemed to be some... unexpected side effects.
The princess’s increasing eagerness and acceptance for their soiled padding was not something she anticipated. Ever since messing herself for a second time, Luna in particular had been taking any and all opportunities she could to sit and grind her shit-filled diaper against herself. It started as a just a subtle squirming but quickly devolved into a clearly lust-driven pursuit of perverted pleasure.
Celestia, though not quite as far gone as her sister yet, was on the verge. If nothing else, her infatuation with Luna’s messy behind had become very obvious. She clearly didn’t mind seeing her sister like this. If anything, she almost looked envious.
Once back in the throne room, Starlight had originally planned to force them to sit in their own filth as further humiliation for the rest of the day... but they likely wouldn’t be objecting to that notion now. Honestly, if it weren’t for the scent-containing bubbles she’d recently cast over them, she would’ve already changed their diapers.
Though, to be honest, it was kind of amusing to watch them try to pleasure themselves with their own waste. She decided to let them be for now. As she sat in her throne, watching the two alicorns moan as they aggressively swapped saliva, she smiled. The spells she’d cast on them this morning were only temporary... though that could certainly be changed...
“L-luna~!” Celestia cried, gasping as she felt her sister’s hoof push down into the back of her diaper, rubbing the soaked padding up against her burning marehood.
Behind her, Luna panted as she tended to her clearly desperate sibling, all while slowly moving her hips up and down as she ground her own mess into part of Starlight’s throne. She moaned as the mushy filth inside squished and spread all over her backside, though at this point there was little left that it hadn’t already permanently stained.
Standing at the bottom of the throne’s marble steps, a blushing advisor tried his best to ignore the pair as he reported to Starlight. The unicorn listened attentively, despite the messy display just a few feet from her hooves. A stray whine from Celestia did finally get her attention.
“P-please, I need it Starlight!” She cried out, gasping sharply as Luna’s hoof pressed into her soaked diaper again.
“Now now, Celly, I’m busy with somepony very important right now~. I’m sure you’ll be all too satisfied before the ah... ‘sun’ goes down tonight~.” She replied casually, turning back to the advisor as Celestia’s pupils shrunk.
*Pfrrrraaaarptchk~!*
Suddenly, the indent of Luna’s hoof was overwhelmed as Celestia's padding bulged around it. She could feel the weight of her sister’s load emerging as it contorted and bled through the durable padding. Celestia’s eyes began to roll upwards as her whole body shuddered, barely keeping conscious as the feeling of poop reaching her pussy finally made her climax.
“C-celestia!” Luna cried shortly after, finally driven over the edge herself as she let her face press up into the mushy seat of her sister’s messy diaper.
Starlight hummed as she watched the two collapse out of the corner of her eye, finally passing as they embraced each other’s backsides, resting their faces in each other’s messy padding. She smiled, satisfied with keeping them like this for the rest of her rule...
