Chapter One

The Padded Shapes of Nightmare
By Scribe Feather
✶✶Chapter One✶✶

Twilight sat there in the middle of the enchanted nursery, mouth hung open as she stared in utter disbelief. Stretching before her opened up a long stoney hallway, the perfect hiding place for a magical relic that would fix all this chaotic diaper stuff. Only much to the unicorn’s shock, the place was completely empty, containing only an empty display stand at its center.

“It’s gone,” she muttered to herself, “how could it be gone...?”

She just couldn’t believe it. Sitting in the middle of a large nursery that was once the large catacomb found deep under Canterlot, Twilight felt the last bit of her normality slip away. Her mouth hung open as she just stared at the empty hall. Gone. Whatever she and her friends came here for was gone. Tears began to well up in her eyes as crying seemed to be the only thing the confused and baffled unicorn could do.

Meanwhile her friends around her continued to be part of the chaos in the nursery, falling victim to their own unique fates in the various corners of the room. Pinkie continued to have her diaper changed over and over again by the large stone golem that guarded the chamber. Applejack and Rainbow Dash continued their childish competitions to see who was better potty trained. Fluttershy grinded away at the soft stuffed animals that surrounded her, each one eagerly awaiting their fate. Rarity busied herself with playing dress up with an ever expanding wardrobe. Each one of them remained completely unaware of the strangeness of their new reality. Even as the world began to solidify in its new, twisted state, such drastic changes remained unnoticed by its denizens.

Moments later, Princess Celestia entered the scene with her head held high and dressed in only a thick, frilly diaper and a pink diaper attached to her crown like some sort of headdress. She wore a familiar, regal smile as she walked with patient grace into the catacombs. She remained unphased by the strangely brightly painted stone walls or the lingering stench of fresh linen and baby powder. All was normal for the princess and nothing was out of place.

She first spotted Pinkie Pie who was still stuck on the table with the huge stone golem changing her diapers. A large pile of yellow diapers sat beside the changing table, each one saturated well beyond their limits of absorption. The golem continued grinding away, changing Pinkie’s diaper the moment she got it full enough.

“Hi Princess Celestia!” Pinkie called out with a big smile as she finished up using yet another diaper. Her words only quivered a tiny bit as she expelled a rapidly filling bladder’s worth of urine into her diaper, sighing with relief once she finished.

Celestia closed the gap between the two, smiling softly down at the urine soaked changing table. The plastic padded top of the table had become shiny and slick as dozens of dribbling diapers left their mark all over the furnishing. She hardly batted an eye at the strong stink. “Hello again, Pinkie Pie. I see you’ve made a new friend down here.” She nodded acceptingly to the large stone golem who towered over her, but hardly broke away from its endless diaper changing.

“Yep! When we came in here lookin’ around Stony came up and offered to change my diaper!” Pinkie smiled up at the golem, but the stone being didn’t react, simply rolling up her old diaper and sliding a fresh one underneath. “He’s really good at it!”

“What could you girls possibly need down here?” Celestia asked as she examined the cold stone walled room, “we have nurseries in the castle.”

Pinkie opened her mouth to answer what she initially thought was an easy question. “Well yeah, but we were down here because...” Only the answer didn’t come as simply as she would have hoped, “b...because...” Suddenly she couldn’t remember a thing.

As she racked her brain for the answer, her bladder loudly sprayed into the waiting diaper. Just before the golem could finish taping up the new one, Pinkie had already soaked it.

Princess Celestia knew the answer right away and smiled, “because after going through so many diapers, you wanted your own caretaker to be around to change you!”

Pinkie’s concentration fell to the wayside when she heard Celestia’s suggestion. It was a brief distraction, but just enough to make her deep thought disappear. Suddenly the princess’s suggestion seemed so believable. “I...guess that’s it...” Pinkie answered, her lower half being lifted into the air as yet another soaked diaper was removed from under her.

“Well then it seems that you’ve found the perfect pony for the job,” the white alicorn smiled, motioning towards the golem. “Ah, but Stony might be more useful after we make a few adjustments.” Celestia’s horn glowed for a second, masking the golem in a bright, yellow light.

The light made the golem glow, enveloping it in a blindingly white flare. The ball of light pulsed before shrinking to half its size. Inside the spherical casing of light a magical metamorphosis was occurring, transforming the golem into something new. When the light finally dissipated it left a bright white earth pony with a silver mane. The pony’s features now had a soft curve to them, heavily contrasting the jagged cut edges of the golem’s stoney shape. In fact, the pony seemed completely different from the stone golem save for its piercingly blue eyes that resembled the golem’s gemstones.

“For a more travel sized diaper changer,” Celestia added, presenting the newly transformed pony like a prize.

Pinkie was beside herself in disbelief. She looked up from her spot on the changing table at her newly formed caretaker. “Stony? Is that really you?”

The white pony remained mute, barely making a different expression to reflect his mood. He just looked at the pink pony, apparently recognizing the name as his own now.

“Why yes, this is Stony through and through,” Celestia started, “he will be there to change you whenever you need it. And since you can be quite the piddle pony, I think you’ll like what else your little friend can do.”

The golem pony blinked for a moment before walking over to a urine puddle on the floor. When he placed a hoof into the liquid, his white coat soaked it up, causing some of the yellow coloration to leech into it like a sponge. Once absorbed the moisture remained trapped in his hoof with neither a drop or dribble falling from it.

Pinkie’s eyes lit up and her mouth hung open. In her absolute astonishment she even failed to notice her newest diaper had begun to leak over the edges of the changing table. “And his WHOLE body can do that?”

“But of course,” Celestia answered, “his legs, his body, his head,” she continued rather proud of her work, “everything is absorbent and will dry back to normal a few hours after use.”

“He’s perfect!” Pinkie cheered, hopping up in place, causing a smattering of urine to dribble out of her soaked diaper.

“Now why don’t you take your new friend up to the castle and show him around,” Celestia suggestion, magically lifting Pinkie off the changing table, ”its too nice of a day to be cooped up down here in the dark.” Celestia gave the two ponies soft pats on the head, “I’ll be up in a little bit with your friends.”

“Sounds like a party!” Pinkie squealed, hopping up onto Stony’s back. She landed with a padded thump as her diaper squished against the stallion’s back. Any urine that leaked out of her overflowing diaper was quickly soaked into the stallion’s coat, leaving a faint yellow stain around the area.

Stony was emotionless through the whole thing, loyally taking Pinkie’s padded weight like a champ. He seemed to retain his golem strength despite now being mostly made up of soft diaper padding.

“What are we waiting for, Stony!?” she loudly exclaimed, nudging Stony’s padded sides with a kick of her heels. “Let’s go!” And with that said the two were off, Stony galloped out of the room making rustling sounds like a diaper with every move he made.

Celestia chuckled at the happy pony as she ran off with her new friend. After adjusting her new headdress, she walked deeper into the catacombs and into the nursery proper. Immediately the scents of the nursery intensified, hitting the princess with smells of lavender and old diapers. She scanned the room, eyeing the group of ponies who lied scattered across the area while being involved in various activities. An otherwise absurd and shocking sight for a normal pony, but Celestia took it all in plainly, casually walking through the room like it was an everyday occurance.

The closest of the ponies was Fluttershy, who was much too involved in her lewd playtime with the piles of plushies to take notice of Celestia walking up to her. The yellow pony grinded her slick diaper against a dog plushie, moaning and whimpering between humps. Occasionally she would pause, only to grunt or sigh filling up her diaper a little more. The squishy back of her stinky diaper seemed to only entice the pony to change to another plushie and grind against it for a little bit.

A rough circle of sentient plushies stood around the sex crazed pony as she had her fun. Despite having stitched on smiles and unmoving black bead eyes, the plushies seemed to enjoy the sight, waiting patiently for their turn with the diapered Fluttershy.

When Celestia finally caught up with the yellow pegasus, she was taking a break from her endless grinding, panting on top of a large rabbit plushie as beads of sweat soaked into the big stuffed animal. A diaper filled with a lumpy mess and slick juices bellowed grossly between her legs.

“Aww, you were having fun with your plushies?” Celestia smiled, “well we certainly can’t let you play down here in a dingy nursery like this.” The plushies around them nodded in agreement, each one drawing the conclusion that playing outside the nursery would be much more fun. “Why don’t you pick out some of your favorites and head on upstairs. There’s plenty of room up there for you to have fun with your new fluffy friends.”

Fluttershy gasped happily before grabbing the large rabbit plushie out from under her. She gave the plushie a big squeeze before waddling off. A handful of other plushies followed her out, walking in a single file line. It was like a tiny parade out of the nursery, with Fluttershy’s sagging diaper leading the way.

Celestia chuckled at the adorable sight and watched to make sure the group left the room safely before continuing on her way. Her eyes lingered especially on Fluttershy’s diaper that so cutely sagged behind her as she trotted out of the room with her fluffy friends.

Next up in her travels were Rainbow Dash and Applejack who were still in the midst of their overly competitive potty training. The two diapered ponies had spent the entire time fighting over the single training potty that sat between them, yelling at each other and calling each other the meanest insults their toddler minds could think of. Quite often when one did manage to win a spot on the plastic potty, they wouldn’t even bother taking off their diaper before showing the other just how better they were at using the potty like a big pony.

“Baby!” Applejack yelled, trying her hardest to push Dash off of the potty.

“You’re a baby!” Rainbow Dash so cleverly responded, pushing back at the other pony.

“You’re a BIGGER baby!” Applejack screamed back.

“Girls, girls, now settle down,” Celestia slowly waved a hoof, “neither of you are babies.”

“Then how come we got no suns on our potty charts?!” Applejack huffed. She held up her chart with a big pouty face. The piece of paper kept track of a month’s worth of failed potty attempts with each day marked with a storm cloud or raindrop. Rainbow Dash had her own potty training chart with similar results, though she would claim that she was more potty trained because she managed to make it to the potty today. And the fact that her diaper was thoroughly used was completely missed by the cyan pegasus.

“Oh Applejack. You don’t need sun stickers to show how good you are. You use your diapers and that’s all that matters.” Celestia gave the pony a pat on the head. That seemed to make Applejack smile with pride.

“But I use my diapers DOUBLY!” Dash swooped in between the two, practically pushing Applejack aside with her swollen diaper.

“You both try so hard,” Celestia assured, “I think both deserve a star sticker on your potty charts for trying so hard.”

“A star!?” Applejack and Dash exclaimed with the biggest smiles.

“Yes, but only if you can get back up to the castle together,” Celestia smiled, “and I want to see the fullest, biggest, most well used diapers around your waists when I get up there.”

The two ponies practically tackled each other as they dashed for the nursery exit. Celestia watched their diapered rumps waddle off into the distance, disappearing past the hallway. They ran with such excited energy with their legs hardly able to keep up with them.

Celestia chuckled to herself and shook her head in such a motherly way. It was only a matter of time before the competitive pair of ponies went back to their old ways, yelling and clambering for every opportunity to prove they were more grown up than the other. Probably cause quite the ruckus for everypony around them too.

She turned her attention back to the nursery, scanning the room for her next mark. A pouty Rarity came waddling into view. A big, fluffy pink dress ballooned around her waist, covering her body in ruffled layers. A large, pointy princess hat stood on her head as she sat there feeling down in the dumps. She let out big, audible huffs every so often. Attention grabbing sounds of displeasure she had hoped somepony else would hear.

“Oh my! What a pretty dress, Rarity,” Celestia chimed in, fawning over the outfit like an encouraging mother.

“I guess so,” the white unicorn huffed, “but it’s still not quite right. I need to keep looking.”

Scattered around the unicorn were a number of outfits all thrown into sloppy piles on the floor. Onesies and dresses, costumes and coveralls all laid discarded after a brief moment when Rarity tried them on. Hundreds of outfits she had gone through in such a short amount of time and none of them seemed to be quite right.

“You know, I heard Princess Cadance is looking for somepony to help her pick out the perfect dress,” Celestia started, “says that every dress she tries on ‘just doesn’t look right’ too.” Rarity raised her head, the mention of dresses catching her attention. Celestia continued, “I want you to help her. You’ll have an entire kingdom of crystal ponies to try your dresses on. Hundreds of ponies to choose from!”

“You really think I’d do well?”

“I couldn’t think of a better pony,” Celestia happily answered, “the crystal ponies might even enjoy your used diaper fashion line as well!”

That made Rarity’s eyes light up, “oh yes! I could show them some true Ponyville culture with my latest project!” Already her mind swarmed with ideas she wanted to try out. And with the promise of a whole city’s worth of ponies to try stuff on, she had a seemingly endless supply of test models.

“I’m sure they’ll just love it,” Celestia answered.

Rarity beamed, struck with new found artistic drive and passion. She happily trotted out of the nursery with her chin held high. A rack of dresses came floating out with her as well as a diaper pail filled to the brim with used diapers. Raw materials for her clothing project. Celestia waited at the side as Rarity’s caravan of fashion supplies rolled out of the room. She smiled at the opportunistic pony and waved an encouraging hoof as she departed.

Last, but not least, Twilight Sparkle remained in the nursery, sitting off to the side next to a row of cribs. Tears streaked down the pony’s face as sniffles and sobs could be heard echoing in the quiet room.

“Twilight?” Celestia walked in beside the diapered pony, “Twilight, what’s wrong?”

The purple unicorn sniffed and turned to face her mentor. She wiped some moisture out of her red eyes before answering, “I...uhm...I don’t remember...” She was crying for so long she had completely forgotten why she started to in the first place.

“Don’t remember?” Celestia answered with a concerned tilt of her head, “so you’re sitting here crying about nothing?”

Twilight paused, already she could feel her tears begin to dry up, “I guess so...”

“Well we can’t have that,” Celestia said as she wiped a tear off of Twilight’s cheek, “why don’t we go upstairs and I’ll change your diaper.”

That seemed to catch Twilight’s interest. The purple pony pulled herself off the ground, her well used diaper sagging grossly between her legs. She wiped the few last remaining tears out of her eyes. “Can I have the one you’re wearing now?!”

Celestia looked down between her legs. Her diaper was almost completely soaked and tinted yellow from front to back. She had been putting off her own diaper change for awhile now, seeing her princessly duties were more important at that moment. “Well,” she knew her answer right away, but she wanted to tease Twilight a bit. “I don’t know...”

“Please, Princess Celestia! Please!” Twilight was now on her knees begging, grabbing one of the white alicorn’s front hooves. “I want to wear your warm, squishy diaper! Please!”

Celestia smirked, she couldn’t say no to a face like that. Her horn glowed a mystic yellow as her diaper and Twilight’s started to glow as well. The diapers were effortlessly untaped and slipped off of their waists. In one aerial dance, the two garments floated through the air, switching places with one another. Celestia’s soggy diaper looped around Twilight’s waist, taping itself around her snuggly with expert precision.

Twilight wore the biggest smile as she felt Celestia’s warm diaper press against her. The diaper was thoroughly used and would likely need a change once Twilight went back up to the castle. “Mmh! Thank you, Princess Celestia! Thank you!” The excited pony swooped in for a big hug, squeezing Celestia’s leg tightly with a smile.

Celestia chuckled softly as she carefully slipped Twilight’s diaper around her own waist. The diaper felt clammy and cool once taped on. It seemed that her pupil didn’t wet it as much as she wet hers. “Oh you’re quite welcome, Twilight. You’ve earned it.”

She then suddenly felt plastic rustling rubbing against her leg. Peering down she saw Twilight rubbing against her with her eyes closed. The naughty purple pony was humping her mentor’s leg.

“M-mph! Your diaper feels so good,” Twilight murmured as she panted. She had grown energized by the scent of her mentor’s diaper, even more excited seeing Celestia there with her. “I-I wanna wear your diaper forever!”

“Oh don’t worry, Twilight. There’ll be plenty of time for that,” Celestia chuckled as her horn began to glow. “But first,” Celestia began to say, lifting Twilight up as she humped empty air, “let us get out of this dingy place. All your friends are waiting upstairs.”

Twilight moaned, dry humping the air a couple times as her soaked diaper just barely stayed in place around her waist. “Okay...” she answered, only briefly holding off her pelvic thrusting for a moment, “can I ride on your back?”

“Oh I guess you’ve been well behaved. Sure,” Celestia chuckled as she floated Twilight over onto her back. Twilight’s diaper squelched loudly against her, becoming dangerously close to leaking out onto Celestia. The risk of springing a leak however didn’t concern the purple unicorn as she quickly slipped back into humping not moments later.

“S-so w-warm!” Twilight groaned, leaning in close to Celestia’s back. Her overly saturated diaper molded around the princess’s back, keeping Twilight in place as she slid the crinkly plastic up and down her length.

“Oh yes, we’re gonna need a diaper change very very soon,” Celestia chuckled with her motherly tone of voice. She pivoted on a hoof and began trotting out of the room. Her jaunty stride inadvertently bounced her passenger, driving Twilight wide with each bounce she had in her step.

Every so often Celestia’s bouncy walk caused her old diaper to dribble onto her back, soaking into her coat and cooling the fur around Twilight. What the purple unicorn didn’t rub against with her warm and soaked diaper became chilly in the dank cave air.

“And a bath,” Celestia added, “the both of us.” But Twilight didn’t hear a word of it, she was much too busy moaning and panting, carelessly slapping her soaked diaper front against Celestia.

And with that the last inhabitants of the enchanted nursery left, leaving behind discarded clothes, toys scattered across the floor, and of course a fair amount of diapers, both used and new. The condition of the catacomb nursery foreshadowed the inevitable fate of Equestria itself that even now sank deeper into the diaper obsessed reality that had taken shape.
