✶✶1✶✶

The bedroom was humid, filled with naughty scents of taboo as two bodies coiled around each other in passionate embrace. The two loving bodies remained covered up by a warm blanket with a limb or two momentarily sticking out of the cover. A rainbow tail flicked in the thin ribbon of moonlight that seeped through the parted window curtains. A purple wing stiffened tightly and twitched against the springy mattress. Heavy pants and shivering breaths could be heard from the two as they continued their sexual dance.

Pants became louder and moans became more frequent as the intimacy accelerated to it's breaking point. Heart beats quickened as their bodies flared up in temperature. The two blanket covered bodies quickened their hot embrace, rubbing against each other faster and faster. In one, carefully synchronized thrust their bodies shivered and the two ponies moaned loudly. The sought after climax was finally reached, leaving their bodies satisfied and their love for each other even stronger.

For the next few moments, the two body lumps remained still. Only the sound of panting could be heard in the room. Soon after, a rainbow maned head poked out of the cover, the pony taking in a deep breath of the cool air.

"W-wow," the pony said, still catching her breath as her insides cooled by the nightly air. "Twilight...That was wonderful."

A second purple maned head peeked out of the bed as well, resting her head against the other. "I'm glad I'm not the only one who enjoyed it. Glad you don't save all that energy for your tricks, Dash."

It had been two years now that Twilight Sparkle and Rainbow Dash had been dating and things couldn't have been better. Tonight was an important night filled to the brim with romantic gestures and passionate events to celebrate their two year anniversary. A quiet walk in the park, a candlelit dinner where they got lost in each other's eyes, and finally sensual sex to wrap the entire night together in a neat little bow.

With all those fanciful details behind them, the two ponies were now left in the warmth of each other's embrace, cuddling under the warm bed sheets.

"Have you been practicing?" Dash prodded a hoof into Twilight's side.

"What? No no no, of course not," Twilight bashfully shooed the hoof away along with the teasing, "I just uhm...found this book."

"You and your books," Dash said with a roll of her eyes.

"It was just a silly ol' book that I found in the library's private section."

"The section you don't let Spike snoop around in?"

Twilight nodded with a blush, "a-and for good reason."

"I would say so."

There was a natural pause in the conversation as it naturally transitioned to another topic,

"This was a lovely night, Dash. Thank you," Twilight started.

"Hey, don't mention it, Twi. I enjoy spending time with you."

"No, but I mean it. Everything was lovely," Twilight sighed, nuzzling her head underneath Dash's chin. "Didn't think the restaurant would be so crowded though."

"Didn't think such a fancy restaurant would have that kind of problem on a Tuesday. A lot more kids there it seemed."

Again, there was a natural pause as the two enjoyed each other's company.

"Hey," Twilight started again, resting her head on Dash's shoulder, "what do you think about adopting a foal?"

"Heh, a foal?" Dash smirked, "Come on, I can barely take care of myself!"

Twilight chuckled and rolled her eyes. "Oh you're exaggerating."

"I don't even know if I'd be good at it," Dash added. "I mean...I can't even change a diaper..."

"Never learned how?"

"I don't see how I could have. I mean it's not exactly a skill everypony picks up."

"I suppose so..." Twilight added.

The conversation seemed to die off after that. Rainbow Dash thought nothing of it, seeing the talk about changing diapers as idle blather. After awhile she decided to call it a night and turned off her bedside light. She slipped under the bed covers and slowly drifted off to sleep.

Twilight, on the other hand, was kept up at night, thinking things over. She reviewed the events of the evening before. The articulate pony looked over all that happened that night. She smiled at the romantic dinner that Dash surprised her with. She shivered at the passionate sex they had not hours ago. All in all, it was a wonderful evening that would go up in her memory with all the other good times she's had with the mare.

One constant that remained strong in her thoughts was Rainbow Dash's response to her foal adoption suggestion. She never realized how little Dash knew about taking care of children, but now that she was looking back, it only made sense. It was never an issue before because foal talk never came up before. Now that it was out in the open however, Twilight felt a worried voice call out from the back of her head. She knew Dash would make a wonderful mother...but now the voice sounded louder and more prominent.

✶✶2✶✶

Morning dawned as the cloudy spring sky was brightened by the rising sun. Dash groaned as the sun shined in her face, forcing her to get out of bed. Her eyes squinted as they adjusted to the morning light, her limbs popping as she moved about. In her half awake, fuzzy vision, she noticed that Twilight was already up and gone and her spot in bed was left empty and unmade. The studious alicorn was always more of an early bird anyway.

Dash mumbled some incoherent sounds that sort of sounded like words as she forced her body to move. Step by step, she pulled herself away from the warmth of the bed, to the hallway outside the door, and then slowly down the steps leading to the ground floor. Occasionally her mouth would open for another yawn as she shook her head awake.

The ground floor of the Golden Oak library was quiet and oddly empty when she arrived. A quick scan of the rooms resulted in not finding anypony else. Spike was no where to be found and Twilight was missing as well.

A flutter of worry tickled the back of Rainbow Dash's mind seconds before the library's front door started to open. Much to her fleeting relief, it was Twilight. "You're up early," Dash commented sleepily, eyeing the various paper bags that floated around the alicorn.

"I wanted to get some shopping done," Twilight answered as shopping bags levitated through the room and to the far wall. The brown paper kept whatever items that were inside hidden from sight. The only thing Dash had to go on was the various shapes that the bags took.

"Were we...out of milk or somethin'?" Dash asked inquisitively, looking over the four or so bags that sat on the ground.

"Well...no...I had to get a few more...things..."

"You're bein' awfully twitchy, Twi. Is something wrong."

"I'm just nervous you might say no..."

"No to...what?"

Twilight took in a deep breath of air. "You know how...last night you said you couldn't change a diaper?"

"Oh that? You're still hung up about that?" Dash shrugged as she started to walk towards the grocery bags with the intent on putting whatever they were away. "It's no big deal if it means that much to ya. I can take like a parenting class or somethin'-"

"What if we changed each other?" Twilight quickly interjected.

Dash paused, taking off guard by Twilight's interruption. She looked at the other pony with a raised eyebrow, unsure how to process the comment. "Change each other's...diapers?"

"I was just doing some thinking," Twilight said, "if we had each other to experiment on we'd be able to tell each other right away what the other's doing wrong or doing too much of or forgetting..."

"Change each other's...diapers?"

"I've already planned things out, it's simple. We spend three days in diapers together, use them whenever, and then change each other whenever needed."

"But what about work? Spitfire'll wonder about me if I miss too many days of work unannounced..."

"I've already thought of that. I'll call off work for the both of us, get the days free so we can learn."

"And Spike?"

"Already out visiting Princess Cadence and Shining Armor," Twilight explained, "they're doing a little ceremony for the anniversary."

In Twilight's eyes, this plan worked out perfectly in their favor. Among the two of them they would be able to learn helpful information. She rationalized that doing this during the time Spike was away to attend a ceremony celebrating the day he saved the Crystal Kingdom would be the best chance they had. That, paired with the days off their respective jobs was a perfect recipe for this rare opportunity.

Dash paused as she mulled it over. "I don't know...I mean...changing each other?"

"Well...How about we make it a bet?"

"A bet? Hmph! You don't do bets."

"Yes, but you do. I bet you can't last three days in diapers."

"Only three days?" Dash scoffed at the insultingly easy bet. "What do I get if I win?"

"Well...If you win," Twilight tapped her chin as she did some quick thinking, "you win...My autographed copy of Daring Do and the Golden Time Piece. First edition."

"The Golden Time Piece? But you love that book!"

"I think it's fair considering what I'm asking from you."

Dash smirked as she nodded affirmatively. She extended a sure hoof towards the other pony with a confident expression. "You got yourself a deal. Three days in diapers!"

"It's a bet," Twilight said, shaking Dash's hoof with her own.

"Guess I know what's in the shopping bags, huh?"

Twilight nodded, her horn glowing as the grocery bags started to glow as well. Out from the four bags floated out an array of items that they would likely use in the next three days. Most predominantly was a small case of adult sized diapers, the words 'Dry Clouds: Adults' and 'Extra Absorbency' blazoned across it's main face in eye catching, white text. Alongside the pack floated a tub of wipes, baby powder, a plastic changing mat, and an empty diaper bag.

Dash watched the items float closer to the two, paying extra attention towards the pack of diapers. "So do you just wanna change each other...Or..."

The question made Twilight blush. Despite her imminence excitement to put Dash in a diaper and vice versa, something in her mind suggested to keep those thrills under wraps to avoid scaring the pegasus off. "Well I guess if you wanna...just put on our own then I guess we could always..."

"Let's change each other!" Dash quickly interjected, suddenly back pedaling her words, "you know...for...for practice. You know?"

"Sure!" Twilight said with a blush, "for practice."

With that said the plastic changing mat was gently laid on the middle of the library floor. Twilight volunteered to be changed first, laying her body down on top of the crinkly mat as Dash prepared the needed supplies.

A fresh diaper was slipped out of the package, crinkling ever so faintly in Dash's hooves as she tested it's texture. The diaper's design did it's best to emulate a child's underwear which was a bit strange considering it was made for adults with incontinence. Each pair had a slight variation of design with little shapes of flowers, stars, and baby animals decorating their surfaces. Dash dwelled on the diaper's design a bit longer than one normally would as she examined it from different angles and took in the faint sounds of it's plastic shell.

Dash wasn't sure how long she spent staring at the object before her mind snapped back to reality. She looked up to find Twilight still patiently waiting on the changing mat. "U-uhm...lift your legs for me, will ya?"

Twilight complied and Dash proceeded with the diaper change. Her novice approach lead to a couple fumbles as the changing progressed. A moment had to be spent to decode which end was the front end of the diaper and she would frequently ask Twilight to lift her rump once more to readjust the length of the front part of the diaper. Once the area was powdered with a rather generous amount of baby powder, Dash taped the garment around Twilight's waist a bit loosely. In her eyes, as long as it didn't slip off Twilight's butt, she did her job.

With the change officially concluded, Dash helped Twilight up to a sitting position as the diaper crinkled loudly under the alicorn's weight.

Twilight blushed, finding a whole medley of emotions swimming in her body. A special warmth and happiness filled her heart as she took in the new pillowy sensations that came with the diaper. It awoke a new sensation of embarrassment, child like innocence, and in a faintness of the word, arousal.

A shaky hoof lowered itself onto the cushy diaper, pressing into the fluffy, flower printed diaper. She slowly ran the hoof across the front, starting from the base and ever so gently running it up to the tape landing panel.

Dash broke Twilight's daze with a quiet clearing of her throat. "I should...probably get changed too, right?"

"O-oh yeah...right..." Twilight tensely cleared her throat as well, scurrying off the pad to make way for the cyan pegasus.

Twilight quickly went to work and changed Dash into her first diaper. Much like Dash's attempt, there was a lot of trial and error, frequently leading to her readjusting the tapes a couple times before she was satisfied with the fit.

"Alright...now what?" Dash asked, prodding the thick diaper between her legs to test the fluffy material.

"Well now...we just...go I guess," Twilight stated, blushing a tiny bit as her mind teased her of what was to come. She did her best to remain calm as the ideas excited her.

Dash nodded, holding back a big smile as she hopped into position. It was alien to her to just decide to wet herself in the middle of the library, but her spine tingled with anticipation. Her forehooves spread out wide, causing her diapered rump to stick up in the air as she focused. The diaper crinkled softly as she concentrated on letting her bladder go.

Twilight joined in, holding back as much excitement as Rainbow Dash. Rather than approaching the task with brunt force, she decided to help coax her body into cooperating. She attempted to use some mental imagery to help work past her years of solid potty training. She tried to imagine herself in the bathroom, in front of the toilet to ease her bladder's resistance.

The two ponies stood in the middle of the open room like two silly statues, both with their eyes slammed shut and focused on wetting their diapers. Countless minutes passed with them in this pose, yielding no results.

Twilight finally huffed, annoyed at her failure as she broke her pose. "We should have wet ourselves by now!"

"I'm trying, alright?!" Dash huffed as her face reddened. "I need to go, it's just...kinda hard," she added as her eyes moved from her diaper to Twilight's. Her eyes hovered on the other pony's thick diaper, momentarily forgetting what she was trying to do.

"I didn't think it'd be this hard to use a diaper," Twilight stated as she tried to focus on going. "I mean, we go to the bathroom all the time."

"It's harder than it looks," Dash added, grunting occasionally as her bladder wouldn't listen to her. As happy as she was to stand there and piss herself like a foal, her body just wouldn't cooperate. Her face reddened as she began to push, resulting in only a headache and a frustrated huff. "Oh I give up!" She plopped down onto the ground, her still dry diaper cushioning her rump.

"Well there is one thing we could...try," Twilight suggested, blushing a little bit at the thought.

"What, pour water in the things?"

"I was thinking more so an...incontinence spell."

"Maybe," Dash answered back, not at all surprised that Twilight would have a spell or two about anything up her sleeve. "Not...permanent...Right?" She cautiously asked.

"No no. It's just a simple spell that will help us go," Twilight recalled as she remembered the spell. It was an old and under used spell that she once found in a dusty tome one day. It had always been a fantasy of hers to try it out, but could never find the right opportunity.

"Alright, lay it on me!" Dash extended her forehooves, squinting her eyes to brace for the impending spell.

Twilight stood up straight, spreading out her legs in a wide stance as her horn began to glow. She closed her eyes as the magical energies gathered, a growing pressure bearing down on her forehead.

A tingling sensation quickly rushed over the two ponies, starting at their chests and then flowing down their bodies until it reached their waists. The sensation seemed to hover around their bottom halves, penetrating their thick diapers as the magic worked away with it's effects. After only a few short minutes, the tingling faded away. Twilight's magical aura slowly faded. Somewhere in the library a wall clock dinged seven o'clock.

"Hmm, well I don't...feel any different," Twilight looked at her body with an inquisitive expression. Her partner however was silent, causing her to look up. "Did it work for you?"

Rainbow Dash didn't say a word and instead looked at her crotch with wide eyes and a pale face. Her forehooves dug into the padding, pressing deep into it's thickness as it began swelling beneath her. Her thighs squeezed together in a last desperate attempt at hold off the offending sensation that every part of her brain said was wrong.

The two sat there in silence as a faint hissing sound could be heard from Dash's diaper. Twilight watched closely as the padding turned yellow and began to sag. She felt her wings quiver as her eyes intently watched the entire thing.

"I...I..." Dash was completely blindsided, unable to fully explain how she felt when her bladder was taken out of her control. She would have likely been enjoying it however, if it wasn't for the sudden surprise.

"Guess it did work," Twilight chimed in with a little chuckle. "Don't worry, Dash. I'll change you!"

Dash bashfully looked up from her spot on the floor. She felt a small smile grow on her face at the offer. This was going to be an interesting bet.

✶✶3✶✶

The three days Twilight and Dash spent in diapers went by before they even realized it. It felt less like a challenging bet as time went on. In fact, the two seemed more than willing to change each other and jumped on every opportunity to do so. Diaper changes were done efficiently, but not always quickly. It seemed like the two deliberately took longer than necessary to complete the diaper change. Not that either of them complained or anything.

"The time's almost up Twi! In only a few short hours, your book's gonna be mine!" Rainbow Dash lounged on the couch with a smug grin on her face. "I don't know what I was so worried about at first. Wearing diapers is easy and I gotta say, not having to get up to go pee is great! I almost hate to see it go..."

Twilight loudly gasped, interrupting Rainbow Dash's tangent. A heavy mass could be felt pushing out the back of her diaper, freezing her in place. The squishy load forced itself into her diaper, pulling it down with it's weight.

"Twilight?" Dash raised an eyebrow, looking down at the large lump that grew in Twilight's diaper, "Did you just-?"

"I-I didn't even feel it coming!"

"Well it WAS an incontinence spell. Kinda not surprising, right?"

"It was suppose to just do our bladders! I-I didn't think-"

"Didn't think you'd make a big stinky like a widdle bitty diaper baby?" Dash interrupted with a teasing snark.

"Dash! This is no time to kid around!"

"Relax, don't have a cow. No biggie!" Dash said as she hopped to her feet. "I'll get you a new diaper, we'll get you changed, and it'll be over with." And with that the cyan pony trotted to the bedroom closet.

Twilight's legs heavily bowed out as her cheeks still burned red from the embarrassment. She never expected to mess herself so suddenly, especially in front of Rainbow Dash. Her steps were carefully placed, avoiding any slip ups or obstacles to trip on. "If the intensity of the incontinence is off then surely the duration is as well," she mused to herself.

Meanwhile, Rainbow Dash dug through the discarded coats that acted as the makeshift camouflage for their diapering supplies. She tossed the pile of clothes off to the side revealing the plain cardboard box that served as their diaper storage.

"Uhm...Twilight...Is this ALL the diapers you have?" Rainbow Dash called out, looking over the box's contents.

"Of course they are. I had to keep them hidden so one hiding spot is easier than two." She then paused, before raising an eyebrow of uncertainty. "Why?"

Dash held up two white rectangles. "These...are our last two diapers."

"What?!" Twilight was stunned, she never thought they were going through THAT many diapers. "That's impossible!"

"I looked everywhere. This is all we got." Dash tried to convince Twilight, but the moment she was told, Twilight dashed into the closet, digging through the various coats and boots in there.

"There's gotta be more!" Twilight called out as coats and jackets were pulled out of the closet and thrown into a pile.

"You know what we gotta do, don't ya?" Dash said as she watched Twilight's sagging rump crinkle about as she hastily dug through the closet. "W-we gotta go out in public to do some shopping..."

Twilight pulled herself out of the closet, taking a heavy sigh. "I was afraid you'd say that..." She then looked back at her smelly diaper that sagged grossly between her legs. "I'm not going until I get a change though."

Dash smirked, "wouldn't dream of it!"

After Twilight gingerly laid herself down on the ground, the diaper change proceeded as many of the diaper changes had in the past three days. The big different for this change however, was coping with the foul smell that quickly filled the room once Dash opened up the diaper. She cringed as she held her breath, carefully wiped Twilight's butt clean of the brown mess.

The dirty deed was taken care of as quickly as possible as Twilight stared at the ceiling with flushed cheeks. The alicorn laid absolutely still as Dash continued to take care of her messy accident. Dash would have likely made some teasing comment about how foalish Twilight looked or how cute she looked in a mess diaper, but the strong stench kept those comments silent, not wanting to waste good oxygen as she continued. Once the diaper change was finished, Dash quickly disposed of the messy diaper and Twilight gathered her things, mentally prepping herself for the public exposure ahead.

The two traveled to the Ponyville Supermarket, the town's one stop shop for almost anything a pony could need. The newly added store took up a large lot in the new part of town, attracting large crowds since the day of it's opening.

The supermarket was a large building standing roughly two stories tall. It contained a large, open expanse inside, providing plenty of space for shelves and a multitude of products all lined up in neatly organized aisles. Quiet muzak played away on the market's overhead speakers as ponies did their shopping. The numerous aisle contained a wide variety of items that attracted shoppers with their trusted brand names and vibrant packaging. Ponies pushed along metal carts as they journeyed through the store, piling in the items they came for.

Dash and Twilight joined the masses and did their best to blend into the crowd. They kept their heads down, too embarrassed to look at anypony in the eye as they made a beeline for the diaper aisle. The two most likely attracted attention with their exposed diapers loudly crinkling everywhere they went, but the two were too terrified to notice. Dash especially grabbed a couple stares from other patrons as her lumpy diaper butt waddled past them as they shopped.

The diapers shared aisle space with foal care products such as bottles, wipes, and teething rings. The variety of items lined the two shelves with a wide array of brands catching the buyers’ eye with their buzzwords and brand names. The diverse brands of diapers lined the walls with their various sizes and steadily ranged from infant to adults with a multitude of absorbency options to choose from.

The two diapered ponies quickly found their brand of diapers and tossed a bunch of packages into their cart. "Okay, next we gotta get the wipes," Twilight said as she looked over the piles of diapers that occupied their cart, counting them to be absolutely sure they had enough for a worst case scenario. "Dash?" Twilight turned around and saw Dash frozen in place.

Dash stood in the middle of the diaper aisle, legs spread out as her face grew red. Surrounded by the infantile scents of the many brands of diapers on the shelves, Dash began to grunt quietly.

"D-dash...Are you?..."

Dash only nodded, shutting her eyes tightly as she continued to push. Faint farts seeped out of her diaper as she began pushing out a heavy load. Her bowels slowly emptied into the waiting diaper, pulling at the soggy garment with it's weight and leaving faint lumps in the back. Her cheeks flared in embarrassment as she publicly filled up her diaper where she stood.

Twilight blushed as well, trying her hardest to look away from the spectacle. No matter how hard she tried, she found her eyes trailing back to the squatting pegasus, locking on the ever so faint bulge of her diaper. Dash looked so cute squatting like that like a toddler, Twilight could just barely keep her own legs from quivering at the sight.

The two stood there frozen in the middle of the aisle, attracting a few passing glances of other shopping ponies. Dash was the first to move again, closing her nervous legs as much as the full diaper would allow. She looked up at Twilight with a red face as a signal that she was finished. "Tw-Twilight?"

Twilight just stared for a little while longer, her mind conjuring up fantasies and brief daydreams about what she just witnessed. "O-oh! R-right...Uhm...Wipes!" Twilight took a nervous gulp, hoping Dash didn't notice her staring. "C-could you grab a tub of them? They're right behind you."

Still blushing up a storm, Dash turned around to face the handful of moist wipes that sat on the shelf next to her. She quickly grabbed the first contain she saw, wanting to get out of here as quickly as possible. She waddled back to the shopping cart and tossed the wipes into it, "I got the wipes! Now can we just get out of here?!"

Twilight blinked, shaking her head. "Y-yeah yeah, sure. Let's go and pay."

The two quickly waddled out to the registers, the faint stench of Dash's accident quietly trailing behind. During this busy day, the shortest line they could find was one with five or six ponies already waiting. No matter how full their diapers were, it looked like a wait was unavoidable. They hopped into a line that appeared the shortest and did their time.

The smell of Dash's diaper surrounded the two as they nervously waited for the line to move. Slowly but surely, ponies got their items paid for and went off on their way with minimal stares back at the two diapered ponies. The middle aged mare in front of them sniffed loudly and turned around for a moment. She only looked at the two for a moment and then looked at Dash's diaper that now darkened in the back from her mess. She didn't say anything and simply raised an eyebrow and turned back around.

Dash kept quiet, finding it difficult to be snarky and loud when she had the messy diaper tugging at her waist. She continued to look away and cover her full diaper for the entire time they stood in line. Twilight handled the transaction, stuttering only a tiny bit as she exchanged looks and payment with the cashier. The cashier didn't say anything about her diapers or even the strong stench that came with the two. He simply completed the transaction, praying that the smell would leave shortly after the diapered ponies did.

At the end of it, the two waddled quickly out the front doors of the store, diapers crinkling behind. Dash felt a wave of relief flow over her once they left the populated store, happy that they were finally heading home after that unusually long shopping trip. Oddly enough, deep down in the back of her mind, there was a quiet sense of excitement from the experience.

Once the two were safely back home, Dash took in a big sigh of relief, plopping down on the floor the moment they returned. She laid down ever so carefully, meticulously minimizing any unnecessary movements that might lead to spreading the mess in her diaper more. The smelly mess squelched under her weight, now showing through the white padding as a dark brown spot.

Twilight proceeded to levitate their shopping bags over to a wall for future sorting. "Alright, we have all the supplies we need," she said as she pulled out a fresh diaper from the new package, floating the container of baby powder and wipes along with it. "It should keep us from wandering out until I have this spell figured out."

Dash looked up between her legs, "meaning...?"

"Meaning we might be in diapers for a little longer then expected," Twilight answered back, carefully placing the diaper changing supplies beside her as she kneeled down between Dash's splayed out legs. Making sure to breath through her mouth, she slowly began to pop the tapes of Dash's bulging diaper.

"You know how long?" Dash asked as stared up at the ceiling, cheeks flaring up as her voice shook a tiny bit.

"Tough to say," Twilight simply responded with a similar shaking voice and blush. "It may be permanent, I don't know," Twilight continued talking as she floated the scented wipes over to Dash's exposed nether regions. She found that these diaper changes went by easier if they busied themselves with some distracting conversation. "I'll have to work on fixing this. In the meantime we need to take care of the more...difficult part."

"Difficult?"

"Spike's still out. Which means we can't send letters," Twilight sighed, swapping the messy diaper out for the clean one. "Which means we'll have to show up in person to get more time off work."

"Well...Look, we can split it up and make it easier for both of us," Dash commented, still staring up at the ceiling while, for a moment, forgetting that she was getting her diaper changed. "I'll talk to Spitfire, beg her for more time off and you can go to Celestia and try to see if she'll excuse you from...whatever you do..."

"I guess that's the best chance we got," Twilight said as she finished up the diaper change.

"Don't forget the powder," Dash quickly added.

✶✶4✶✶

Rainbow Dash hiked up into the skies to the Wonderbolt's headquarters. While Twilight dealt with her embarrassing ordeal of meeting with the princess, Rainbow Dash mentally prepared herself for the humiliation that would soon come to her. She never thought she'd be flying up to the Wonderbolts, ponies who practically idolize her as one of their best fliers, in a diaper.

The Wonderbolt’s central base of command sat on top a tall plateau that stood among the fluffy clouds of the sky. Without a hot air balloon or some sort of accurate teleportation spell, the area was almost impossible to reach for unicorns and earth ponies. The flat area was large enough to hold a runway, a small group of sturdy buildings, and a medium sized courtyard where pegasi frequently did their morning stretches in. There was no visible vegetation save for a bluish mountain grass and small berry bushes that could withstand the high altitude and cold.

Dash landed softly outside the main office building, drawing the attention of a couple staring ponies who gawked at the thick, crinkling garment that hugged the cyan pegasus's rump. On the outside she seemed calm and focused, but on the inside she was panicking and worrying, bashfully aware of every set of eyes that even glanced in her direction. Her nervous bladder decided to take this moment and leak a tiny bit into the diaper, causing the padding to swell up a tiny bit as she walked. She quickly scurried inside, making a beeline for Spitfire's office.

Spitfire was hard at work in her office, buried deep in piles of paperwork and forms that required her signature and thorough inspection. The tedious work was time consuming, but a necessary evil when commanding the Wonderbolts. Tall stacks of paper and books piled up high around Spitfire, the busy mare slowly picking away at the large workload.

Suddenly there was a knock on the door.

"Come in," Spitfire said, not even looking up from her work.

Nervously, Dash slowly opened the door, peeking her head into the office. "U-uhm, Spitfire?"

"Ah, Rainbow Dash. I was wondering when you'd show up. Back from your vacation?"

"Y-yeah about that," Dash’s cheeks reddened as her words struggled. "I was wondering if I could...extend my vacation"

"Extend it? I feel I’ve already been very generous giving you what you got on such short notice,” Spitfire explained, "what could be so important that you need to request an extension? Did a loved one die?"

"I-I just figured I would need to extend it for...business."

Spitfire scowled at the answer, "either you give me a good reason or I expect you back in the ranks tomorrow."

Dash let out a heavy, defeated sigh. She reluctantly pulled the rest of her body into the room, her diaper squishing faintly between her legs.

Spitfire simply raised an eyebrow, her eyes locked on the diaper. "Dash, if this is some kind of joke..."

"I-it's not! Trust me, I wouldn't even THINK to wear...well..." Rainbow Dash's words trailed off before she began again. "D-do I have your permission or not?"

The other mare let out a sigh. "Well, considering the circumstances and your current ahem condition," her eyes trailed back down to Dash’s diaper, "I'll give you another three days."

"J-just three?"

"You're really pushing it, Dash."

"Sorry sorry. Uhm...Thank you..." And with that, Dash bowed her way out of the office, just barely holding back a straining bladder as she left. Once she was out of the stern, watching eyes of Spitfire, however, her bladder instantly cut loose, loudly hissing into her diaper. She leaned against the door and let out a sigh of relief. "Least the worst part's over." Dash simply stood there and waited for her misbehaving bladder to empty itself, figuring there was no sense trying to stop it now.

The diaper swelled between her legs, warming up her nether regions as the padding soaked up her urine. A small tingle down her spine persuaded her to watch the diaper as she peed in it, eyes locked on the growing yellow spot. After what seemed like hours, her bladder finally emptied, leaving her with a delightfully warm diaper.

Dash tested the diaper with a shaky hoof. She pressed her hoof deep into the swollen padding to test it’s soggy state. The diaper check slowly turned into a rub. That sensual rub was shortly followed by another rub and before she knew it, Dash was rubbing gentle and slow circles into the crotch of her diaper. The world melted away as she leaned her head back against the door, feeling her body tingle with naughty sensations.

The primitive part of her brain kicked in, urging her to continue and ignore everything else around her. She licked her lips as she dug her hoof deeper and deeper into the urine soaked diaper. Her breathing became shaky and shallow as the diaper sloshed about beneath her rubs.

“What are you doing?” a voice said out of nowhere, breaking Dash’s daydream.

Dash’s eyes suddenly shot open, her hoof quickly swinging away from the yellow diaper in a millisecond. She was caught! She looked to her captor, a Wonderbolt cadet who just stood there and stared at the mare. The other pony wore a shocked and disgusted expression on her face.

“I...I was just uhm,” Dash stammered with her words, looking down at the bulging diaper that hung between her legs. “J-just about to change!” And with that Dash turned and ran the other way down the hall, her wings doing their best at covering her swollen diaper that bounced around her waist.

Her ears and cheeks became hot with embarrassment as she scurried off as quickly as she possibly could. Her pride and ego burned under the public humiliation that she allowed herself to be caught up in. She moved as quickly as her legs would take her, her gait bowed out by the thick diaper.

The diaper attracted a lot more attention now that it was fully yellow and obviously well used. Many Wonderbolts of varying ranks could catch a glimpse of the diapered pony as she dashed through her walk of shame. Not that Dash would have noticed. She was much too busy staring at the ground with wide, petrified eyes.

Things got much easier once she lifted off the plateau, soaring far away from the prying eyes of the other pegasi. She flapped her wings and flew up into the clouds, hoping the clouds would help hide her diaper.

✶✶6✶✶

Dash returned home after her errands as quickly as her wings could carry her. She rushed into the library in a blur of color, slamming the door behind her. The leaky diaper between her legs swayed about as it lagged behind her movements.

"Sweet Celestia, that was embarrassing," Dash stated in a heavy breath, her back leaning against the closed door. "I tell ya, Twilight, Spitfire is an intimidating mare to work for." It was then she looked up and examined the room. Twilight was nowhere to be found. "Twilight?"

The library was completely silent as Dash looked around. Her ears strained for any sign of activity. She slowly made her way upstairs to the second floor, searching each room in search for Twilight.

Her ears then picked up some rhythmic crinkling coming from the bathroom. The bathroom door was left open just a crack, allowing quiet sounds to leak into the hallway. With perked curiosity, Dash walked in closer to the noise and peeked in through the crack.

Twilight was seen kneeling on the tiled floor, both forehooves digging deep into the crotch of her soggy diaper. The yellow diaper squished and crinkled under the pressure. Her wings remained erect as she sensually rubbed her hooves up and down the swollen front of the diaper. She bit her lip with half closed eyes, her wings fully erect behind her. Occasionally a quiet huff or shaky moan slipped past the aroused pony’s lips.

The pony pleasured herself through the diaper. Her hooves slid up and down the length of the diaper ever so slowly and sensually. Her crotch warmed underneath as it tingled with orgasmic electricity.

For a minute or two, Dash just watched through the crack of the door. She even had half a mind to stick a hoof down her own diaper and begin masturbating right then and there. But she knew it was morally right to make her presence known. She slowly peeked her head into the room. “T-Twilight?”

"Dash!" Twilight exclaimed, scrambling about a bit as she struggled to get back to her feet.

The cyan pegasus blinked a couple times, slowly processing the surprising sight. "Twilight, I..."

"It's not what you think!” Twilight hastily replied with a squeak “I was just in here to make a few adjustments! The diaper was a little loose!"

Dash looked down at the swollen garment that sagged between the alicorn's legs. The padding was bunched up tightly in the middle, it's plastic shell wrinkled from rapid movement.

“Were you...masturbating in them?” Dash bluntly asked.

“N-no, I was just...” Twilight exhaled a defeated sigh. "It's true. Diapers really turn me on..." She couldn’t look Dash in the eye, failing to even raise her eyes off the floor in shame. "There's just something about how they hug your waist and crinkle and...s-swell up when you...I'm sorry you had to see me like this. I shouldn't even BE in here! What was I thinking!"

Dash quickly intervened Twilight's rant with a swift kiss on the lips. "Twilight, it's alright," Dash gave her lover a trusting hug. "I couldn't be happier."

Twilight blinked, unable to comprehend the response. "What do you mean?"

Dash smirked, "You're not alone, miss crinkle britches." Dash smirked as her forehoof shot up and dug deep in between Twilight's thighs. The warmth of the alicorn's diaper squished against the invading limb. In that same moment her back legs began to bow out, her tummy tightening as she pushed. Her diaper began to sag between her legs as a new, smelly load filled it. "Think you're gonna have all the fun?"

"Oh Dash!" Twilight leaned in with a big kiss on Dash's lips.

The kiss slowly devolved into moans and sensual rubbings. Dash’s hoof dug into Twilight’s warm diaper front as Twilight’s forehooves found their way near Dash’s lumpy diaper butt. Her hooves sunk into the lumpy padding, squishing the stinky lump around inside the other pony’s diaper. Their bodies laid close to each other and twisted against one another on the cool tile floor.

Both of the ponies vibrated with arousal as every inch of their body screamed with pleasure. Their hooves moved about each other’s diapers as their mouths continued to kiss. Their diapers began to grind against each other, smushing the thick padding between the two.

Slowly the two slipped down to the cool floor, remaining coiled around each other in aroused bliss. Dash’s diaper squelched loudly under her as her butt pressed against the bathroom floor. Her wings became stiff as she felt her smelly mess squish around inside her dirty diaper.

Twilight fed off of the other pony’s arousal, grinding her swollen diaper front against Dash’s diaper. She began to bounce on top of Dash’s padded front, biting her lip as arousal bubbled up in her body. Dash panted loudly as the bouncing caused her butt to bounce on her smelly mess, further fueling her arousal. The bouncing and crinkling grew louder and louder as both ponies felt their wonderful climax build up as well. Heated panting grew louder as time quickly went on.

Finally, in wonderful synchronized pleasure, the two diapered ponies gasped loudly. Their bodies shivered as electric orgasms jolted their bodies, filling their diapers with a third kind of mess. Twilight bounced on top of Dash a few more times, steadily growing slower as they slowly eased themselves down from their diaper fueled frenzy.

Twilight slowly moved her warmed body down close to Dash’s side in the afterglow. She hugged the cyan pony’s side as she smiled. Dash gave Twilight’s head a light kiss, smiling just as much.

Their diapers would surely need a change, but for now the two laid there in post orgasmic bliss, barely even noticing the cold tiled floor under them. And for the next half hour, the two just cuddled on the floor, surrounded by the sexual stench that hung heavily in the room.

Dash finally broke away from the cuddle, giving Twilight a sensual kiss on the lips. “Let’s go get you changed, little miss frisky,” she lovingly said as she pulled herself up. She noted the heavy weight that tugged her diaper down, the seat of the garment growing a dark brown spot in it’s center.

“After you, stinky britches,” Twilight smirked back, pulling herself back on her feet. She gave Dash’s sagging diaper a firm smack on it’s lumpy back as they filtered out of the room.

The two slowly made their way into the bedroom where Twilight made herself comfortable on the floor, ready for her diaper change. For the past few days the two ponies always changed their diapers in the bathroom. Now that they knew that both of them enjoyed it, the diaper change felt more romantic. The floor the bedroom seemed more personal and was noticeably more comfortable.

Dash didn’t mind changing Twilight first and in fact took her time gathering the needed supplies so that she could stay in her heavily used diaper for a little longer. Twilight laid on the carpet covered floor patiently as Dash slowly trotted to the closet, pulled out a new diaper, gathered the wipes and baby powder, and then finally returning to the alicorn.

Rainbow Dash started by giving the warm front of Twilight’s diaper a sensual rub or two. “Looks like you this diaper up good!” She grinned.

“You’re one to talk,” Twilight teased back, eyeing the sagging, brown padding that hung between Dash’s thighs.

“I’m not on trial here,” Dash replied, slowly untaping the swollen diaper’s tapes. “Besides if I remember correctly, somepony rather enjoyed my little ‘accident’.” She continued to tease Twilight, wiping her urine soaked crotch with some wipes as she talked.

Twilight grinned before leaning her head back. She contently stared at the ceiling as Dash lovingly changed her diaper. She smiled to herself, feeling a warm flutter in her belly as she was cared for.

Dash then carefully lifted Twilight’s legs into the air, pulling the used diaper out from under her and replacing it with a nice and fluffy one. A gentle layer of baby powder quickly followed after that.

Twilight couldn’t help but wiggle her legs a tiny bit as a new diaper was taped around her waist. There was something refreshing about a new diaper, so dry and fluffy inside. She wondered how long the diaper would actually last.

“Okay, crinkle butt, get up. It’s my turn,” Dash nudged at Twilight with a hoof. After the alicorn rolled out of the way, she plopped down in her place, diaper sagging obscenely between her legs. “I must warn you though, it’s preeeetty stinky!” Dash covered her nose with both forehooves, stifling a giggle as she played.

Twilight played along by plugging her nose with a hoof and sticking her tongue out in mock disgust. Ever so carefully she began to untape the diaper one tape at a time. Once released, the heavy diaper fell open, revealing Dash’s dirty deed inside. Her magical carefully wiped Dash’s butt clean, steadily making a pile of dirty wipes in the middle of Dash’s old diaper.

Dash put on a cocky smile, not even trying to hide the fact that she was enjoying herself. It was rather exhilarating to make such a smelly mess and have somepony else change her. It was hot in it’s own special way. She confidently laid there with her forehooves behind her back.

The wipes and Dash’s well used diaper was rolled up into a ball and tossed into the diaper pail alongside Twilight’s. A new diaper was expertly taped around Dash’s waist after a rather generous amount of baby powder was sprinkled on her butt.

With their diaper changes concluded, Twilight slowly lowered herself down on top of her freshly diapered mate. She gave Dash a big kiss on the lips.

“I love you, Dash,” she affectionately said.

Dash embraced Twilight in a big hug, pulling her down closer to the ground. “Love you too, Twilight,” she responded with mutual feelings.

When night fell, the two cuddled up close in bed. The cool night air was kept at bay by their conjoined warmth. It almost felt like they snuggled closer than they ever had before. Diapers crinkled quietly under their bed sheets as they slowly drifted off to sleep with smiles on their faces.

✶✶7✶✶

The next day the two ponies slept in, spending a good part of the morning just snuggling with each other in bed. Their diapers crinkled under the bed sheets as the two basked in each other’s embrace, hugging close to each other’s body. They loved each other deeply and it felt refreshing to cuddle.

Ever since they started wearing diapers, the two nervous ponies started to drift away from each other in bed. Their worries kept them apart at night, keeping them from enjoying each other’s company.

Twilight especially would always worry that she would begin playing with herself at night, only to wake up to Dash scowling at her. She worried that if she was ever caught rubbing herself in her diapers Dash might think less of her or assume she wasn’t satisfying enough as a mate. The purple pony just could never work up the courage.

But once they discovered each other’s strong diaper fetishes, their passion drew them closer once more. Now they fell asleep with their diapers firmly pressed against each other and woke up to the intoxicating scent of wet diapers and muffled squishing. Despite the curse, things couldn’t have been better.

Dash was the first to wake from their half awake snuggling, rubbing a tired eye as her mouth opened up for a big yawn. She gave her diaper a long rub starting from the base of her tail, up between her legs, and up to her crotch. Quite wet.

Twilight slept soundly next to her, curled up in a light ball as she snuggled a pillow. The pillow was deeply wedged between the purple pony’s legs, pressed firmly into her diapered crotch as she laid there. Her diapered rump was facing Dash, beckoning to the pegasus to give it a check.

By checking Twilight’s diaper Dash found it wet and had a sizable lump in the back from a recent mess. The diaper check woke Twilight up, making her roll around in bed to face her lover and inadvertently squishing the mess inside her diaper. She didn’t seem to mind and instead smiled up at her diapered mate.

Dash gave Twilight a deep kiss on the lips. “Good morning, diaper butt,” Dash said, leaning over to the other pony. “Sleep well?”

“Like a baby!” Twilight exclaimed, pleasantly stretching her limbs out as she smiled.

Dash took this opportunity to press a hoof into Twilight’s soaked diaper crotch. She slowly squished the padding, fondling the alicorn through her diaper. “Another wet night for the pee pee baby?” She teased.

Twilight’s wings stiffened underneath her as she moaned subtly. “Mph, I’m not the only one,” she said confidently, pushing a hoof of her own straight into Dash’s diaper.

Dash playfully squeezed the hoof inbetween her thighs, thrusting it deeper into her full padding. “What? Are you going to punish me?”

“Mmm, I just might,” Twilight grinned as she gave Dash’s diaper a rub or two. “Maybe some corner time or maybe I’ll pull you over my knee and give you a good spanking.”

“Good luck trying to do that without your hoof,” Dash smirked proudly, keeping her thighs tightly squeezed around Twilight’s invading hoof.

Twilight tugged at her trapped hoof, but it wouldn’t budge. She then felt a growing warmth creep around her limb. This just sparked another impish idea, “or I just won’t change your wet diaper. Make you sit in it.”

This made Dash’s wings stiffen as she slowly lowered her body down onto Twilight. Her thighs released the hoof as the diaper pressed deeply into the other squishy garment. “Oh? But then it’ll get all stinky and you’ll have to-”

"Knock knock!" A familiar voice echoed from downstairs, freezing the two playing ponies instantly.

Twilight was the first to look up, gasping in surprise. "It's Pinkie! What's she doing here?" She harshly whispered.

"How am I supposed to know?!" Dash responded with the same whispered tone.

"We haven't heard from ya in awhile and wanted to check on ya'll." A second voice could be heard as well.

"Applejack too?!" Dash hissed in shock.

"Everypony must have come over," Twilight concluded, "we're going to have to say ‘hey’."

"But we haven’t even...finished...” Dash tilted her head towards her heated crotch that burned with itching arousal.

"N-no time! Let's go." Fighting back the same sexual urges as Dash, Twilight nudged her mate out the bedroom door.

Composing themselves and shaking off the sexual burning that had built up in their bodies, Dash and Twilight hastily climbed downstairs. Suddenly the diapers that they had filled up for their sexual play turned into objects of their humiliation.

Their friends were waiting in the main room when they finally appeared. Applejack was the first to spot them, pleasantly smiling. “There ya’ll are! We were beginning to worry about...you...two...” Applejack’s word trailed off to silence as her head slowly tilted to the side. Her eyes focused on the swollen diapers that the other two ponies wore. The orange pony stared at the well used diapers for a few moments with a look of distaste and puzzlement.

“Y-yeah...S-sorry we haven’t talk to ya guys in awhile,” Dash blushed, trying to keep her mind off the diaper. “We’ve been kinda...busy...”

“I...Guess that explains why ya’ll disappeared this whole time,” Applejack didn’t change her expression, unable to properly process what she was looking it. Dash could feel the other pony’s stare burning into her diaper. She tried to cover it up with a wing, blushing with embarrassment as she could hardly look at Applejack in the eye.

“I brought you two some special cake!” Pinkie Pie appeared out of nowhere, holding up a delicious looking chocolate cake. Twilight did her best to smile in appreciation, but the nervousness of having her friends seeing her and Dash diapered was too much for her to speak.

She couldn’t imagine how long she could have kept it up if Fluttershy didn’t suddenly intervene. “Should we come back later?” Fluttershy meekly added, blushing a tiny bit as she tried not to stare.

“No no, it’s fine,” Twilight quickly responded with a shaky voice, “this is just a result of a small...spell I accidently casted on both of us a few days ago.” Twilight’s voice continued to reflect her nervousness, but the studious pony did her best to remain calm. These were their friends after all. “I’ve been trying to figure out a cure for a few days now.”

“So, you two have spent the last few days in...those?” Rarity spoke up, avoiding the word ‘diaper’ like it was profanity.

“W-we’ve changed inbetween accidents!” Dash quickly added. It was very likely that Rarity wasn’t implying that, but the nervous pegasus felt it was necessary to emphasize that fact. “I-in fact we were just about to change out of them when you guys arrived.”

Seemingly out of nowhere, Pinkie Pie hopped in front of the visiting group with a happy spring in her leap. "Ou! Can I help!"

"No need, Pinkie. It's fine. We can change each other just fine," Twilight tried to dismiss Pinkie’s offer, but before she knew it the pink pony was inches from her, prodding her messy diaper with a hoof.

“You’ll leak all over the place if you keep taping those on so loosely,” Pinkie stated, “I can show ya how to do it right. I changed the Cake twin’s all the time when they were a foal!”

“B-but we really don’t-” Twilight tried to decline, but in an instant Dash and she was pulled up the steps by the excitable pink pony.

In one smeared blur, Pinkie pulled the two ponies into their bedroom, closing the door behind her for privacy.

“Now who wants to get changed first?” Pinkie asked with a happy chirp.

The other ponies stood there frozen. Their minds still hadn’t caught up with the hyperactive pony, paralyzed among all the confusion.

“Let’s see,” Pinkie said, tapping her chin with her hoof. “Eeny, meeny, miny, Dash!” Pinkie pointed a hoof towards Dash and giggled.

“M-me?!” Dash’s voice cracked, “b-but Twilight’s-”

“Your diaper’s looser. You’ll leak if you wet yourself again.”

Pinkie moved quickly and before Dash knew it she was already on her back in the diaper changing position.

Pinkie gave Dash’s swollen diaper a quick, professional pat to check it’s dryness level. “Soaked!” She simply exclaimed before turning her head towards Twilight, “you can sit down while you wait, Twilight. Should only take a minute or two!”

“No no, you’re already being more than generous. I can just go into the other room and change-”

In a split second Pinkie Pie zipped up to Twilight. “Sit doooown,” she said as she pulled Twilight down with a pull of her hoof.

Twilight forcefully plopped squarely on her messy diaper. She was just relieved Pinkie didn’t see her wings stiffen to the feeling.

Dash’s tapes were carelessly ripped off of her soaked diaper and the diaper change began. Pinkie proceeded with the usual steps, handling each one like a routine rather than an embarrassing ordeal that Dash made it out to be. Dash stared at the ceiling during the whole thing. Her cheeks flared bright red as Pinkie expertly wiped her crotch clean of urine. she glanced of at Twilight as the wiping continued and their eyes met.

Twilight bashfully smiled and Dash smiled back. She then motioned towards her semi stiff wings and shyly grinned. She even implishly lowered her hoof and gave her diaper crotch a couple naughty squeezes, all to simply tease the pegasus. If she hadn’t been lying on her wings at that very moment, Dash would have probably popped a wing boner too.

“Next we slip a fresh diapee under Dashie’s rump!” Pinkie happily chirped, replacing the cold, calmy diaper with a fresh and fluffy one. She then gave the area a rather extravagant amount of baby powder, nearly turning Dash’s cyan coat a pure white. The diaper was then pulled up over Dash’s crotch, taped on snuggling around her waist with just the right amount of tightness. “See? Easy peesy!”

Dash’s cheeks wouldn’t stop blushing as she finally closed her legs. The new diaper crinkled loudly as she scurried back to her feet. Her face burned with embarrassment as she bashfully looked at Pinkie. “Th-thanks,” she forced out, completely red faced.

“You’re welcome! Now off you go!” Pinkie said as she gave Dash’s diaper a firm pat on the rump causing a large cloud of powder to ploom out the leg gatherers.

Dash pulled herself away from the sight, her legs feeling like jelly as she fought back the instinct to touch herself. Conflicting emotions of arousal from the diapers and embarrassment from Pinkie changing her left the pegasus conflicted and confused. At the moment, her body could only cope with it by keeping her emotions neutral, unable to react loudly in either direction.

“Alright Twilight, it’s your turn!”

Twilight reluctantly laid herself down, carefully arranging herself to avoid any unnecessary squishing. With Pinkie Pie around suddenly a big stinky diaper was extraordinarily less fun.

Pinkie seemed unphased by the lumpy diaper that stunk up the room once it was opened. She carried through the diaper change much like Dash’s, working efficiently through each step.

Twilight could hardly watch as Pinkie Pie happily changed her diapers. She kept her eyes covered throughout the whole thing, too embarrassed to look her friend in the eye. To make matters worse, Pinkie walked her through each step of the change like she did with Dash’s paying careful attention to the details to ensure she didn’t leave anything out.

She kept quiet through the entire thing, occasionally nodding to Pinkie to insure that she was following the diaper changing tutorial. Pinkie finished up after the same amount of time as she did with Dash, helping the embarrassed Twilight back up to her feet and punctuating the end of another successful diaper change with a couple firm pats to the alicorn’s rump.

“There we go! Now our didees are all clean!” Pinkie hopped in place with a happy chirp. She then hastily guided the two ponies back downstairs.

The other three ponies had already made themselves comfortable for better or for worse.

Much to their embarrassment, Rarity had stumbled across one of their onesies and was closely examining the garment. The white unicorn thoroughly inspected the onesie, making mental notes on how one would make improvements to such a simple piece of clothing.

Applejack took her seat closest to the main door, awkwardly sitting down on a cushion while thoroughly inspecting the area to make sure she didn’t sit on or next to anything unpleasant.

Fluttershy sat awkwardly as well, but for different reasons. The meek pony shyly stared at the floor, periodically looking up to examine her surroundings. Seeing Twilight and Dash in diapers brought forth a vicarious embarrassment, making her quieter than usual.

Rarity was the first to notice the other ponies’ return. “Ah, lovely! You’re back!” She smiled at the freshly changed pony, finding it much easier to tolerate the smell of baby powder more than urine. “I was just looking over this lovely onesie and I must say it’s sparked a ”

“Wh-where did you find that?” Twilight nervously asked, with a blush.

“It was just draped over a table,” Rarity plainly explained.

“Oh is that so?” Twilight shot a glance to Dash. The pink onesie was something of a private matter, usually kept hidden away inside a dresser drawer. She distinctly remembered that Dash stated that she’d take care of the garment earlier.

“Anyway, I do believe I can make a few adjustments.”

“O-oh that won’t be necessary,” Dash added with a nervous quiver in her voice.

“Darling! I insist!” Rarity added, “besides, I’ve been working on Gala dresses for the past month. It’ll be nice to break it up with another project.”

“Guess it wouldn’t hurt,” Dash commented, inwardly excited about the possibilities.

“Hey! Now that you’re freshly changed, you can come with us to Sugarcube Corner!” Pinkie happily hopped in place. She held up her chocolate cake as an enticing example. “There’s an awful lot of sweets there that need to be eaten!”

“I wish we could, really,” Twilight started, “b-but me and Dash need to find a way to fix this thing.”

“Well at LEAST have a slice of my delicious, super special chocolate cake I brought!” Pinkie shoved the plate into Twilight’s face, nearly squashing the sugary mess into Twilight’s nose.

Twilight let out a heavy sigh, “fine!” She leaned in and gave the cake slice a big bite, chewing the hefty mouthful before swallowing, “there. Happy?”

“Yep!”

“We kin help ya’ll look if that’ll help,” Applejack chimed in.

“Well...I suppose more eyes would help,” Twilight reasoned.

With the extra set of hooves, searching through the countless stacks of books was much more manageable. The six ponies were able to sort through the various books in record time, cutting Twilight’s projected workload in half. In their library wide search, the ponies searched for anything that could be used as reference material. They even went as far as regression spells and curses.

Books scattered across the floor, some open to random pages as the search continued. Before long the group made noticeable progress. Each of them searched through hundreds of books, quickly sorting out anything that was unrelated to the cause. A small stack of books of promising titles gathered near the center of the room as others were quickly cast aside and replaced on the shelves.

However, the group’s efforts only lasted a short half hour before Twilight suddenly tensed up. Her cheeks flared up as her wings started to droop to the side, covering her bottom half.

“I-I think me and Dash can take it from here,” she finally said, her words shaking as she did her best to keep her cool.

Applejack was the first one of the group to look up from the many open books that covered the floor. “But we jus’ barely started-”

Her words were swiftly interrupted by an abrupt shove by Twilight. “I-it’s fine! It’s fine! You’ve been very helpful!”

Rarity, Fluttershy, and Pinkie Pie were quickly corralled up along with Applejack as they were shepard towards the front door. The group only had time to say a few words of protest before they were magically nudged out the main door. Twilight quickly shut the door behind them, leaning against it with a heavy sigh.

“Is everything alright, Twilight?” Dash soon asked.

“Well uhm...it would seem that Pinkie’s cake kind of...made me need to go...” Twilight raised a wing, revealing a well used diaper that hung heavily between her legs. The heavy mass was visibly dark brown in the back.

“O-oh!” Dash blushed, “then let’s go get you change, you naughty diaper butt.”

“Then,” Twilight started again, “we best go back to our research. We don’t want to be in diapers forever, right?”

Dash paused for a moment, “Oh...yeah. Right...”

✶✶8✶✶

Every free second of the next day was spent in research. Their time frame was coming to an end and Twilight knew they wouldn’t have long before the effects of the spell became permanent.

Twilight dug straight into whatever research material she could find. Stacks upon stacks of books scattered across the main library floor as many books floated about with a magenta glow. She scribbled notes and cross referenced different spells and curses of similar attributes to find a cure. She felt like she was back in school, cramming for a big exam.

Dash did her best to help the busy alicorn, but the best she could do was retrieve specific books or make sure she had enough reading light. She even would occasionally check Twilight’s diaper in case the studying pony forgot to change.

As the afternoon drew close, Twilight’s princess duties came knocking. Tonight was the night of the Summer Sun Ball, a celebratory occasion that marked the longest day in the year.

The Ball’s importance certainly didn’t come close to the actual ceremony which took place in the morning of that same day, but it still remained one of Canterlot’s biggest and most celebrated events. Any excuse for the prim and proper locals to have a party was good enough for them.

Twilight was very close in her research, but Celestia was insistent. As a princess, Twilight needed to keep up appearances and there was little Twilight could say in objection. And as her mate, Rainbow Dash was forced to attend as well.

A carriage was arranged to pick the two ponies up in the evening before carrying them to Canterlot Castle for the event. Until then Dash and Twilight prepared. Twilight took advantage of every second she could to cram in some last minute studying.

In the midst of their preparation there was a knock on the door. Twilight could hardly pull herself away from the stacks of books that surrounded her so Dash answered it for her. Carefully peeking her head outside, Dash used the wooden door to shield her thick diaper from whoever was on the other side. “Oh hey, Rarity...?”

The white unicorn stood outside with a white box floating beside her. “Oh wonderful! I worried you two had gone off to the Summer Sun Ball already!” Rarity chirped before letting herself in.

“We-,” was all the pegasus could say as Rarity slipped inside, not at all phased by the thick diapers now. “What are you doing here?”

“Well I wanted you to have something to wear to the Summer Sun Ball, I worked tirelessly on a new design I had in mind!” Rarity explained as she untied the little string that held the box together. “I took the design of the onesie and added my own flare to it!”

Rarity levitated two elaborate and lavish dresses out of the box. The delicate garments were lovingly tailored with an exact eye for detail. The two were similar in their ball gown like design, but contained colors that lovingly complimented each other.

For Twilight, Rarity made a dark blue gown that was tastefully accented with shades of light blues and whites. The fabric twinkled in the light, shimmering like a cloudy, night sky. Each layer of fabric was carefully set upon the others to create a blooming plumage at the back.

As for Rainbow Dash, Rarity knew she wasn’t much of a dress wearer, but for an event as important as the Summer Sun Ball it was necessary for her to have one. Her dress contained less variety of color and focused more on subtle design that etched patterns in its white layers of fabric. The edges were trimmed with bands of gold, splitting the dress up into large sections.

Dash examined her dress with invasive hooves, digging through the many layers to understand the garment. The inside of the dresses was made of a soft, almost pajama like material, cleverly hidden underneath the layers of expensive fabric. Digging underneath the many layers of the dress’s skirt revealed a onesie like cover that could be snapped over a pony’s diaper to keep it snugly against their rump.

“U-uhm...Thanks,” Dash said with a puzzled tone.

“Well go on, try it on!” Rarity exclaimed. “I had to make an educated guess about the crotch snaps. I didn’t know how much...ahem, padding to account for.”

At first, Dash hesitated, looking to Twilight for some kind of support or excuse to leave the excitable unicorn. Unfortunately Twilight was much too involved in her research to notice. With a reluctant sigh, Dash began to wiggle into the new dress. The multiple layers required some creative shimmying and some assistance from Rarity, but soon Dash was eventually dressed.

“Ah, you look absolutely dashing!” Rarity chortled with a smile. “How does it fit?”

Dash shifted in place, bothered by the alien sensation of wearing such girly clothes. “It’s...nice, I guess...Thanks,” Dash bashfully murmured. At least it covered the diaper.

“Well then Twilight shouldn’t have a problem with hers!” Rarity exclaimed with relief, “I’m afraid I must be off. I have an upstanding appointment that needs my attention.” Her horn glowed a powdery blue as the main door effortlessly opened. “Do let me know how the Summer Sun Ball was, won’t you darling?”

“Y-yeah, s-sure,” Dash blushed.

Rarity’s timing was impeccable because at that very moment a royal carriage came rolling by the front door. Dash’s eyes met with the armor clad ponies who pulled the vehicle.

“J-just a minute!” Dash hastily exclaimed before ducking back into the building.

Now having to cope with the bulky dress, Dash’s stride had an even more noticeable waddle then usual. Feeling the fabric brush against her body just felt so off to her and would take some getting use to.

With haste, she helped Twilight quickly get ready for the ball. The alicorn’s dress slipped on effortlessly and the onesie snaps on the crotch closed without issue.

“Don’t forget to pack a diaper bag,” Twilight reminded.

“O-oh yeah, right,” Dash answered with a heavy blush. She had almost forgotten.

Canterlot Castle was only a short trip away from the two dressed up ponies. The place was already teeming with activity as A-list ponies from all over Equestria gathered for the grand ball. Elaborate and rich looking carriages lined up near the castle’s entrance, slowly filtering out regal ponies with eye catching dress.

Every inch of the Great Hall was decorated for the occasion. Streamers and banners of red and gold dangled from the tall marble columns around the room. Table cloth covered tables with large bouquets of yellow flowers bordered a wide open dance floor as live music was played by a dapper quartet. Clean dressed waiters carried around platters of tiny food samples on toothpicks to the various groups of ponies that populated the expansive room.

Twilight was quick to make conversation with the first few ponies she met. She would make small talk with the party guests with a well rehearsed, princess smile before moving on to the next group. Dash hastily followed behind as they moved through the dense party crowd.

"Rainbow Dash,” a familiar voice chimed in, stopping the pegasus dead in her tracks. She turned to face Spitfire, dressed in her Wonderbolt dress uniform. “Fancy meeting you here," Spitfire commented casually. "I thought you'd be home considering your...condition."

Dash forced up a big grin. "Heh, well y-you know. Life as a princess's girlfriend," she said as she pulled Twilight close to her with a one hoofed hug. "Gotta be where she is."

"I suppose so," Spitfire answered back, “I hope you’ll be ready for work once your three days are up. I expect you there first thing in the morning.”

“Of c-course! I’ll be there,” Dash quickly said. If everything went as planned, she would be out of diapers by then and everything would be back to normal.

“Good,” Spitfire answered, “just be sure to bring any...extra items if your condition doesn’t clear up by then.”

“Y-yeah s-sure yeah! Got it!” Dash nervously stammered. “S-so I’ll talk to you later. Twilight wanted to try some of the h’orderves before they’re all gone.”

“I did?” Twilight questioned.

“Yes!” Dash answered with a look, “you did...remember?”

“O-oh yes...Positively starving,” Twilight quickly added, “please excuse us, Ms. Spitfire.”

The two quickly slipped away from the situation, practically running in the opposite direction. They moved over to the buffet, a long string of tables that were filled to the brim with platters of food. They sampled the various foods, gathering tasty morsels on their plates before carrying them back into the crowd.

Twilight mingled with various groups of ponies that attended the fancy ball. As a princess of Equestria so tried her hardest to keep appearances up despite the extra padding that hugged her rump. She had a bit more confidence talking to other ponies with the lovely dress cover it.

As she chattered along with Canterlot’s social elite, Twilight sampled the tasty fare that the royal ball had to offer. Only the finest ingredients were used in the large spread of tiny sandwiches, salads, and little cupcakes, resulting in some of the best food she had eaten for awhile. Despite not being hungry at first, the mouth watering morsels definitely perked her interest.

One unfortunate side effect of all the sampling came in the form of a subtle pressure in her belly. She was quick to recognize the feeling after spending so long in diapers. Before too long, she felt her bowels involuntarily push out a hefty load into the waiting diaper.

There was something cute about eating and filling her diapers at the same time. As long as she kept her composure, Twilight was able to enjoy the subtle sensations that came with filling up her diaper. She was in her own little world and didn’t realize it until she noticed Dash giving her a knowing look from across the table.

Twilight cleared her throat. "Dash, could I speak to you in private." She gave Dash a subtle look, motioning with head towards the bathrooms. "I have something I need you to help me with."

"Right right," Dash nodded, "uhm, please excuse us." Dash gave the group a small bow before scurrying off with Twilight.

The two ponies hid away in a nearby bathroom, one of the few that actually locked from the inside. The royal bathroom had all the lavish accommodations for a single pony, containing a sink and toilet of equal regality.

"Let's see the damage," Dash said as Twilight horn began to glow.

The hem of Twilight's dress began to glow, lifting up into the air and folding up on her back. The plastic snaps of the inner onesie strained to hold back the mass of padding that bulged behind it. The diaper sagged low once Dash had unsnapped the garment. The hefty padding weighed down Twilight’s waist, only a few drops from leaking with it almost completely tinted yellow.

"Wow, you really did a number on this one," Dash commented, running a hoof across the squishy diaper.

"I know I know, I shouldn't have waited so long," Twilight rushed, "now can you PLEASE help me change?"

"Little baby wanna change?"

"Dash, this isn't the time."

"I think this is the perfect time. I got a wet little filly here who couldn't make it to the potty."

"Dash-"

"And you said you could hold it during the party like a good girl."

"Dash I..." Twilight then blushed, looking at Dash over her shoulder. "I...I'm a naughty filly."

Dash grinned at this response, feeling a chill slither up her wings. “What do you think we should do to you for filling your little diaper?”

“Oh I don’t know,” Twilight innocently replied, fibbing as a million different ideas instantly filled her mind.

“Don’t know?” Rainbow Dash played along, “well let’s see...” She examined Twilight at all angles, circling her slowly. “Maybe make you go to bed without dessert because you’re so naughty,” she teased, “we could make you write an apology note to everypony who smelled your stinky butt.”

Twilight’s eyes slowly closed as her legs shivered with arousal. “Mmh, please don’t punish me. I’ll be good.”

Dash pulled herself close to the alicorn, hugging her close so that their diapers touched. She could feel Twilight’s mess squish against her own diaper, making sparks fly through her body. “Maybe take you outside and give you a spanking in front of everypony?”

Twilight could only gasp and shiver, pressing her diaper deeper into Dash’s. She let out a long, steady moan. She grinded up against Dash’s body, against her soggy diaper.

Dash responded to the grinding with some of her own humping. The sound of their diapers squishing bounced loudly against the quiet bathroom walls as urine soaked padding pressed against each other. Dash leaned in for a sensual kiss as her hoof stealthily hooked around and pressed into Twilight’s lumpy diaper. Their lips connected, stifling a surprised and aroused gasp from Twilight.

Grinding and humping gradually intensified as their bodies warmed up with arousal. Their limbs twisted around each other, fondling each other’s diapers and kissing eachother so deeply. Moans rumbled from the two diaper ponies’ mouths as each second passed by.

With each hump the two ponies slowly got closer against each other. Their diapers squelched between them as the saturated gels of the diaper shifted about. Dash would punctuated every other hump with a firm spank that smacked Twilight’s lumpy diaper bottom. Twilight could only moan and shiver in response, too aroused to intervene.

Twilight’s moist sex was the first to go, erupting her body into a powerful orgasm as she let out a forced moan. She squeezed Dash close as she flared up with heat and blush. All of the mess was kept inside her diaper that freely swayed beneath her dress.

Dash followed shortly after, growling low as the primal part of her brain screamed in sweet release. Her moist diaper hungerly soaked up the juices that sprayed out of her aroused sex.

Twilight dropped to the floor exhausted. Her limbs splayed out across the floor, exposing her thoroughly used diaper.

Dash took this moment to change the alicorn’s diaper, a skill she was getting rather efficient in. The diaper change took no time at all with each step moving seamlessly into the next one. Twilight was wiped, powdered, and taped into a new diaper before her afterglow could fully fade.

Dash punctuated the end of the diaper change with a kiss on Twilight’s muzzle. "That's not coming off until you've made a big stinky in it," Dash whispered into Twilight's ear with an impish grin.

Twilight simply smiled in her dazed afterglow. That command was just fine for her.

The two rested for a moment or two, allowing their bodies to recovered from the powerful climaxes. Once they were able to stand up without their legs shaking, Dash resnapped Twilight’s dress onesie closed. Her own diaper was dry enough, not requiring a change just yet.

The two slipped out of the bathroom, melting into the party crowd that still bustled with activity. Dash felt a hoof firmly squeeze her butt through the diaper.

"Don't think I forgot about you, diaper butt," Twilight grinned behind her, walking so casually past her.

Dash smirked at the teasing, feeling her cheeks flare up just a tiny bit. Maybe wearing diapers wasn’t so bad.

✶✶9✶✶

The next day Twilight had assembled the required components to her counter spell and not a moment too soon. In mere hours the spell would become permanent.

Spell books and research notes spiraled around the alicorn as she read through dozens of them in rapid succession.

"I got everything we need and not a moment too soon," Twilight chattered, leafing through three books that floated around her head, hastily flipping their pages for her. "Stand still and we'll be back to normal in no time."

"Wait, what if we...didn't cast the spell in time?"

"Then we'd stay incontinent, probably have to re-potty train ourselves all over again."

Dash leaned into Twilight, kissing her deeply on the lips. Her kiss lingered, causing Twilight's magic to fade. Twilight closed her eyes and embraced the other pony with a long breath of air.

Dash then broke the kiss, looking into Twilight’s eyes. "And would that really be a bad thing when we got each other?"

Twilight wrapped her hooves around Dash, cuddling her close as the books around her dropped loudly to the ground. The nearby wall clock struck seven and a tingly feeling rushed over the two. The incontinence was now permanent.

"I think we're ready for an adopted foal now. This week has taught me a lot." "Funny how we'll all be going through potty training with our new foal."

Rainbow Dash shrugged, "thinkin' it'll just be our foal doing it."

Twilight smirked and rolled her eyes, “oh we’ll just have to see.” Her nose then began to twitch before her horn began to glow. Dash was suddenly lifted up into the air, diaper sagging profusely between her legs. “You’ll be needing a change before you go back to work.”
