Reluctant Regression

Though I have done stories that include diapers before, this will be my first attempt at something with more of an ABDL focus. I hope those of you who like that kind of thing enjoy!

Reluctant Regression

"Ah still refuse to believe this..." Applejack murmured grumpily to herself as she squinted up at the underside of a familiar cloud home that hovered over the northern end of Ponyville.

"*Sigh*, Me either darling, but I suppose we did agree to follow through with our end of the agreement." Rarity said, trotting up next to the irritated farmpony as the two of them shared a look of mutual anxiety.

'How in Equestria did she finally do it?!' Applejack thought, still in disbelief that she somehow lost this bet. 'That little pegasus has never come close to winnin one of these bets before!'

Midnight, Roughly Two Days Prior[/i

Applejack gasped for air as she lowered a mug from her muzzle, having just drained it of cider in one long swig. She glanced down to see how the other two were doing, a cocky smirk spreading across her muzzle. Both Rarity and Rainbow Dash were struggling to down the same round she just finished.

And while they were eventually able to pull it off, with Dash slamming her empty mug down on the table in triumph, Rarity looked like she were on the verge of losing her lunch. Her head was continually wobbling and rolling around atop her shoulders, threatening to topple the mare at any moment if she weren't careful.

"Heh, are ya'll sure ya wanna keep this goin?" Applejack snickered, leaning confidently against the large keg standing next to them.

"H-hell yea! Give me a-another!" Rainbow shouted, cheeks permanently tinted red as she then proceeded to try drinking from the same empty mug again.

"One for -HIC!- me too, d-darling!" Rarity giggled hysterically, propping herself up against their table in an effort to stay on her shaky hooves.

The three of them had initially come out to the barn in order to party and celebrate one of the most successful cider seasons the Apple Family had seen in years. But, at some point during the night, after most of their friends had already gone home, somehow the three of them had gotten into a drinking contest. Granted, this was nothing particularly unusual for Applejack and Rainbow Dash, the abnormal addition of Rarity to the mix had been a pleasant surprise. She usually wanted nothing to do with these little competitions.

Colorful bits of confetti still decorated the floor of the barn and a banner was strung across the open barn door. It was the aftermath of your typical Pinkie party, just with a large amount of alcoholic cider thrown into the mix once both the sun and all the youngins had gone down for the night.

"I really don't think ya'll should be pushin yourselves so hard like this. It ain't like either of ya have ever lasted longer than me!" Applejack boasted, though admittedly, she was starting to feel a bit woozy after that last mug full.

"Oh, -Erup- Y-yea?!" Rainbow blurted, nearly falling over as she pointed an accusatory hoof.

"Heh, try as you might Rainbow, you've never been able to pull it off, ya lightweight. Just give up now and spare yourself an even worse hangover in the mornin." Applejack replied with a chuckle.

But before Rainbow could even deliver a retort, some incoherent mumbling got both of their attention. A rather silly expression was stretched across Rarity's muzzle as she braced herself up against the table. Her tongue lolled out the side of her mouth like a dog, letting out a moan of relief as she spread her hind legs slightly.

Suddenly, a forceful stream of light yellow liquid shot out from underneath the fashionista's tail. Most of the mare's urine stream arced down to the ground, but the rest crashed into the underside of her tail and dribbled down the back of her legs.

As a small puddle began to form in the dirt around her hooves, Applejack couldn't hold back her laughter as she watched the fashionista doing something that she'd probably find incredibly humiliating under less delirious and drunken circumstances. Amidst her hysterical cackling though, she failed to notice that Rainbow wasn't joining in on the hilarity.

Instead, Dash was concentrated quite intensely on the small trails of urine that were running down Rarity's hind legs, dampening the mare's pristine coat as they went. Fueled by the alcohol in her system and a pleasant tingling that rose between her flanks, Rainbow Dash suddenly had an idea.

Once Rarity had finally finished unceremoniously emptying her bladder, she rose an eyebrow and looked at the two of them with a dumbfounded look.

"W-why are my legs feel so w-wet?" She stammered, letting loose a very unladylike burp as soon as the words were out.

As Applejack slowly regained her composure, blinking the tears from her eyes, she opened them to find a surprisingly determined pegasus waiting eagerly.

"Wanna m-make a bet?" Dash suggested, much to Applejack's further amusement.

"A bet? Really now? Well hey, if ya wanna lose another drinkin bet, then by all means!" Applejack chuckled, supremely confident that neither of them would last at most two more mugs before passing out. "So, what exactly're we wagerin, Dash?" She asked curiously.

"Whoever l-lasts longest gets to make the other do whatever they say, no matter how weird or e-embarrassing, for a whole d-day!" Rainbow declared, spitting down into her open hoof and holding it out in a familiar gesture the farmpony knew well.

"Heh, sounds good to me!" Applejack laughed, repeating the gesture as she began to ponder what she was going to have Rainbow do.

As their hooves met, the mixing of their saliva officially sealed the bet. But then, before they could separate, a third hoof suddenly joined in on the action, jumping out from the side.

"M-mee too~!" Rarity drunkenly sang in a silly sing-song voice, snorting as she was overcome with a giggling fit due to her dramatic entrance. It also seemed like she'd stuck her entire hoof into her mouth as it was absolutely slathered with spit.

"Uhh, Rarity, are you sure you wanna-"

"YES!" Rarity boomed, cutting Applejack off as she then turned and used her magic to quickly fill up her mug.

Rainbow grinned as the fashionista tilted the mug back, gulping down about half of it before immediately collapsing. Her mug fell to the ground as she was rendered unconscious, snoring loudly with her face down and flanks up in the air.

"Ha, one d-down already!" Rainbow chuckled, turning back to Applejack who seemed a bit concerned for the mare's health. "Now, it's just you and m-me!"

"Hmph, fine then. Are you ready to lose once again, Rainbow Dash?" Applejack asked with a grin, tipping her hat down, unaware that it had gotten swirled around during her laughter.

"I was b-born ready, Applejack!" Rainbow replied, not quite hearing the farmpony's question correctly.

As the two competitive mares turned to fill up their mugs, not too far away, a large red stallion was keeping an eye on their shenanigans. He shook his head as they downed mug after mug of cider, slowly but surely draining the large keg that they'd been provided for the party.

Eventually, one of them did fall. Though, to be honest, it wasn't who he'd been expecting. However, only a few seconds into her triumphant victory cheer, Rainbow was out as well.

Wandering over so he could take them all back to the house, he blushed upon seeing Rarity's embarrassingly exposed position, her tail flicked up over her back.

"...Yep..."

"I still don't get it, how did she win?!" Applejack growled, stomping her right hoof angrily as she refused to believe what Big Mac told her that following morning. Though at the same time, she knew him well enough to know that he hadn't been lying.

"Well, while I myself cannot really remember much of this 'bet' of ours, nor most of that night as a whole, I suppose I did agree to it according to your brother." Rarity sighed. "Oh, but I'm sure this won't be all that bad. She is one of our friends after all." She assured though Applejack wasn't entirely convinced that this would be so simple. Who knew what that mare would have ready for them after finally winning a drinking bet after all this time...

Up above, the front door of the large cloud home suddenly swung open as a Rainbow haired pegasus stuck her head out over the edge of the floating abode. Grinning as she spotted them waiting for her down below, with a flap of her wings, she glided down.

"Bout time the two of you slowpokes got here! I was beginning to think you might've chickened out!" Rainbow chuckled.

"Yea, yea, whatever. Now would ya kindly tell us what nonsense you want us to do for you?" Applejack grumbled, hoping to get this over with as soon as possible.

"Heh, alright. Here, both of you need to drink these first." Rainbow said, holding out two small vials of shimmering blue liquid.

"And... what are these things for?" Applejack questioned, not trusting the strange concoctions.

"I... I do believe that these are the same potions Twilight makes to let us walk on clouds?" Rarity explained, recognizing the vial's contents as she squinted down at one of them.

"Yep, cus the two of you are coming up to my place for the first part!" Rainbow confirmed.

"First part of what?" Applejack inquired with a risen eyebrow.

"Oh, you'll see, hehe~..."

"You want us t-to do WHAT?!" Rarity exclaimed, eyes wide as saucers as she refused to believe what she just heard.

"That's right! The two of you are gonna be my cute little foals for the rest of today!~" Rainbow repeated with a grin as Rarity struggled to form words.

"What do you mean 'little foals"? Applejack asked, dumbfounded.

"I mean that, well... First of all, the two of you are gonna need these." She explained, darting over to one of her dressers before yanking out two large crinkly objects from the bottom drawer. Two adult diapers to be precise.

One was bright orange in color with red frills while the other was white with a purple trim that ran around the leg holes. More noticeably, however, were the two cutie marks prominently displayed over each of their seats, a large red apple, and a cyan diamond. As the owner of the former sudden realized what Rainbow was implying, she felt her face turn red.

"There is absolutely no way that you're makin me put one of those things on!" Applejack boomed, stomping her hoof silently on the cloudy floor of Rainbow's bedroom.

Rarity, meanwhile, was still staring at the foalish undergarments in a stunned silence, blushing deeply as she eyed the padding that was clearly made with her and Applejack in mind. Despite what she was being told to do, she found herself wondering who exactly Rainbow had gotten them from in the first place.

"No worries AJ, cus neither of you are gonna be the one putting them on you," Rainbow said with an almost evil grin.

She gestured back towards her bathroom, it's a door ajar, revealing what appeared to be some kind of supersized changing station which jutted out from one of the walls. A sense of dread washed over Applejack as she gulped.

"Now come along AJ, it's about time I got you all padded up~"

Applejack glared up at the ceiling, doing her best to not acknowledge her current situation. Unfortunately for her, that didn't stop Rarity's whining from reminding her.

"Ugh, these things are far too tight around my hips! And why in Celestia's name do they have to be so big?!" She complained, having just emerged from the bathroom now wearing a diaper of her own.

"Alright Rares, go play with your little friend in the playpen over there," Rainbow instructed her, talking as if she were actually speaking to a foal. "But don't tire yourself too much, we've got a big day planned..."

With that, Rainbow turned and flew out of the room, leaving Applejack glaring at the doorway she'd disappeared through as a grumbling Rarity waddled her way through the open baby gate of their 'playpen' which Rainbow had apparently built for them ahead of time. Various colorful toys and large-eyed stuffed animals filled the small enclosure.

"I cannot believe this is what she's makin us do." Applejack groaned as Rarity slowly sat down. Their every movement was punctuated with more crinkling from their diapers.

"Me either, though she could have at least gotten a larger size. For Celestia's sake, she could barely fit my tail through the hole!"

Applejack rolled her eyes as she tried not to think about the embarrassing process she'd been forced to undergo herself not long ago. There was something so wrong on so many levels about letting one of her friends, especially somepony like Rainbow Dash, diaper her. She wasn't looking forward to whatever bizzare things Rainbow inevitably had in store for them next.

"Hm? Oh my, I can't believe it!" Rarity suddenly gasped, getting AJ's attention.

She'd floated over a few of the toy blocks that were stacked over in the corner of the pen and was spinning one around in the air in front of her.

"Sweetie Belle used to have a million of these, oh aren't they just adorable!" She gushed, bringing over a few more. "I used to play with these with her all the time when she was little... though back then she was always trying to hog them..."

Applejack rose an eyebrow as Rarity began to stack them, starting to construct something as she floated over the rest of the wooden cubes.

"Are you seriously playing with those things?" Applejack asked incredulously, surprised that the mare had so quickly gotten over the whole diaper thing.

"Shush Applejack! I'm concentrating!" She replied, leaning in as she tried to balance one of the blocks at a particularly precarious angle off another.

"Alright, my two little angels, Mama's got something very special cooked up for you~!" Rainbow announced as she returned, carrying a small tray atop one of her hooves. "Oh? I see somepony is already having fun with their new toys." She chuckled, seeing the tower that Rarity was meticulously crafting.

"Yea, she certainly is." Applejack grumbled, crossing her hooves defiantly as Rainbow touched down inside the pen.

"Aww, is somepony feeling grumpy wumpy?" Rainbow cooed, though she was unable to hide a cocky smirk from showing itself for a moment. She was clearly enjoying this. Applejack just glared back at her, much to the pegasus's amusement. "Well, I've got some fresh refreshments for both of you that I'm sure will make you feel all better."

She lowered the tray to reveal two large baby bottles, filled to the brim with milk. Applejack blushed at the sight of the one with three apples on it.

"Ehm, Rainbow, do we really have to drink out of those?" She asked, looking to the side awkwardly as she eyed the large nipple at the top of the bottle.

"Well duh, now get drinking! Little fillies like you need your energy~," Rainbow said, handing them their bottles before turning and flying out of the room again.

Both Applejack and Rarity took their bottles, though neither were particularly keen to start drinking from them yet. Though, much to her dismay, a rumbling from her stomach caused Applejack to debate just getting it over with it now. At least Rainbow wouldn't be here to see it. It didn't help that she hadn't eaten or drank anything yet today...

"Well, I suppose there isn't any harm in at least trying it?" Rarity sighed. "To be perfectly honest, I've always wondered what it would be like to drink from one of these things again." She admitted, lifting her up bottle between her hooves. "Oh my, it feels rather warm..."

Applejack watched as Rarity tilted the bottle up to her muzzle. Hesitating for a moment, she eventually opened her mouth and inserted the nipple. Applejack could hardly believe what she was seeing. Never before could she have imaged Rarity of all ponies not only wearing an adult diaper but also drinking from a baby bottle.

"Mhmm!" Rarity suddenly moaned through the bottle, apparently surprised by how the milk tasted. Popping it back out again, she smiled. "Oh, my, whatever she has added to this, It tastes absolutely divine!~"

"Be sure to drink it all gone! That means you too Applejack!" Rainbow called from outside the room.

"Ugh, fine!" Applejack groaned, finally giving in as she snatched the other bottle, sticking it into her mouth.

However, she quickly found some difficulty. As she bit down on the end, she'd been expecting the milk to just come pouring out, only for a few small droplets to drip out onto her tongue.

"You really have to suck on it if you want to get anything, darling," Rarity explained, having already drained about half of her own bottle as she immediately dove back in for more.

Applejack stared down at the bottle jutting out of her muzzle. This was so humiliating. With a great amount of hesitation, she eventually gave it a tentative suckle, not expecting for the milk to suddenly squirt out. Almost spitting out the bottle from surprise, she froze as her tongue finally registered the white liquid. It was... delicious."

Crossing her hooves in hopes of maintaining some form of dignity, she began suckling on her bottle, trying to hide how eagerly she was trying to drain its contents.

'Well... at least It can't possibly get much worse than this...' She thought, praying that she was right as she turned to see Rarity once again playing with her new favorite toys.

'Right?'

"Look, ahm tellin you, put that block right there." Applejack tried to point out, gesturing to a part of Rarity's block tower that was on the brink of total collapse. "I've built enough barns to know a structural weak point when I see one."

"I know what I'm doing Applejack, I'm not a toddler you know!" Rarity replied harshly, quickly placing a few more blocks precariously on the top.

"Hmph, ya coulda fooled me." Applejack grumbled, looking down at the fashionista's diaper.

'What's gotten her so bothered?' She wondered, having noticed that the fashionista's attitude had taken a sharp turn during the last few minutes ever since she'd finished her bottle. She seemed determined to keep moving around.

Rainbow Dash had returned and was relaxing in a chair next to their playpen, looking over a series of kids books that she'd brought in from somewhere. No doubt they'd be read to them soon. Somehow since then, Applejack found herself getting dragged into the construction of the impressively tall tower Rarity had been working tirelessly on. The mare had found a bunch more blocks in a plastic tub that was buried under a few stuffed animals and ever since had been determined to break some kind of fillyhood record set by her little sister.

"No fighting you two," Rainbow warned in a surprisingly authoritative tone from her chair.

Suddenly, following a sharp gasp, there was a tremendous crash. Swirling around, Applejack found Rarity standing there with one of her hooves hovering in the air over a messy pile of blocks that had once been her glorious tower. It seemed to have fallen directly on top of her too.

"I told ya you should've put something there." Applejack huffed, turning back around as she looked for some kind of clock that might tell her how much longer she'd be stuck in here like this. She failed to notice the almost silent hissing sound that accompanied Rarity's shocked expression.

Applejack's ears quirked as she eventually picked up the muffled sound of liquid splashing up against fabric, glancing back only to discover that Rarity’s diaper was slowly expanding, turning a pale shade of yellow. Suddenly the sound stopped as Rarity forcefully clenched her hind legs around the now wet padding, her cheeks blushing bright red. There was a long silence as the fashionista slowly turned to look back at Applejack with shame in her eyes.

"Rarity d-did you just... wet yourself?" Applejack asked, hardly able to believe what she just witnessed. Rarity didn't respond, rear legs trembling and making it clear that she very much still needed to go.

"Aww, was somepony having a little accident over there~?" Rainbow cooed, looking up from her chair at Rarity's tinted diaper with a knowing smile.

“I-I, c-couldn’t…” Rarity choked, the tears welling up in the corner of her eyes as she swirled around to face them and to hide her shame.

“Hmm, well, didn't look too bad. I don’t think you need a change just yet from just a little one like that.” Rainbow promptly decided, turning away again.

“N-not too bad?!” Rarity scoffed. “Rainbow Dash, I just u-urinated on myself! I demand that you get this thing soaking thing off of me this instant!” Rarity yelled, blushing as her every movement caused the wet padding to brush up against her delicates.

“Ah, ah, no yelling young lady! I'm not wasting another diaper if you've only used the one you're wearing a tiny bit.”

"Wait a darn second, Rainbow, are you trying to say that you're expecting us to actually use these things?!" Applejack asked.

“B-but, it's so-“ Rarity stammered, only to be quickly interrupted by Rainbow.

“No buts missy! Else you’ll be going straight to time-out!”

To Applejack’s surprise, Rarity went quiet almost immediately, seemingly intimidated by the same threat she’d likely been given when she was actually a little filly. And strangely, as much as she wanted to give Rainbow an earful herself, she was feeling equally submissive under the pegasus's glare.

Looking back at Rarity who shifted uncomfortably, she cringed as she wondered what it must feel like to have the thick padding that was taped around her flanks to be pressing up under her tail while also soaked with warm urine. It was a thought that sent confusing feelings through her mind.

She watched as Rarity wiped away her tears and then turn back to stare at the pile of blocks which had triggered her accident. She didn’t dare to sit down, though she was clearly too jittery from holding whatever she had left in her system to start rebuilding. She glanced back at Rainbow, biting her lip as she seemed to be deciding something.

Then, to Applejack's immense surprise, she spread her rear back legs and let out a sigh of relief. Immediately the sounds of urine flooding her diaper resumed, causing it to expand even more. Rarity glanced up at the slackjawed farmpony, giving her an awkward conflicted smile. It seemed to take forever for the mare's bladder to fully empty, finally going silent as the diaper sagged down between her legs.

"Rainbow Dash, I've had another a-accident." Rarity quickly asked, clearly hoping to avoid being stuck in her current state any longer than necessary. "Could you please c-change me now?"

Rainbow peered back over again, grinning as she saw how much Rarity's diaper had absorbed.

'Just as planned' She thought, pretending to act surprised.

"Alright, it looks like you've soaked your diaper well enough for a change~." She hummed.

With a surprising burst of speed, she swooped over, picking up Rarity who yelped as her hooves left the ground. It was easy to forget how strong the mare really was.

"Now, that wasn't so bad, hmm?" Rainbow consoled, playfully patting the rear of Rarity's diaper, causing her to squirm uncomfortably as the soaked padding squished up against her marehood. The blush in the fashionista's cheeks brightened as she tried to ignore how nice it had actually felt.

Flying into the bathroom and closing the door behind her, Rainbow left a shocked Applejack sitting alone, stunned by what she just witnessed. Never before did she imagine that she'd ever see Rarity actually wetting herself on purpose. Especially not in an adult diaper...

Truth be told, she was feeling a slight need to go herself for a while now. Though she had no such intentions to go in her diaper anytime soon... would it really be so bad?

“Aaaaand, there! Haha, I've done it! Take that Sweetie Belle!” A newly changed Rarity declared proudly, taking a step back from her finished creation.

“I gotta say, that ain’t half bad for being made of toys...” Applejack replied, looking up at the extravagant and now quite tall tower Rarity had just finished rebuilding. She'd done it much faster this time around too.

“Well, to be honest, I was a bit 'desperate' before, which may have hindered my efforts just a little..." Rarity explained, sounding surprisingly despite what she recently went through.

"Nmf..." Applejack quietly grunted, tensing her back legs as she resisted another brief wave of urgency.

Up until this point, she’d been able to keep her own diaper completely dry, something she was originally hoping wthat way until this was all over. Unfortunately, however, the need to empty her own bladder had been growing increasingly urgent and at an unprecedented rate.

She tried to hide her desperation, but it was becoming difficult. Unfortunately, it seemed like Rarity had already recognized what was wrong

"You know, it really wasn't all... that bad." Rarity said passively, looking off to the side as she pretended to idly play with one of the stuffed animals.

"Huh? W-what wasn't?" Applejack asked, wondering what the fashionista was getting at as she repelled yet another wave of urgency.

"W-wetting myself... It wasn't as bad as I was expecting it to be..." Rarity hesitantly admitted.

"Oh, uh, good?"

"You know... you'll probably feel a lot better if you just... let it happen Applejack-"

"Not gonna happen." Applejack quickly interrupted, stubbornly clenching her rear legs together. She was determined to not give in and bring herself down to that level.

Unbenounced to either of them, Rainbow had been watching closely from over the rim of one of their 'bedtime stories'.

'It seems we're gonna have to do this the hard way,' She thought, grinning evilly.

"Alright, you two" she abruptly announced, getting both of their attention. "We're going on a little trip for lunch."

"A t-trip?" Rarity worriedly asked, praying to Celestia that she didn't really mean...

"Yep, we're all going out to eat, while you're wearing your diapers," Rainbow confirmed, much to their horror.

"What?!" Both Applejack and Rarity gasped at the same time, aghast at the very idea of being seen in public in their current state.

"That is... unless one of you need your diaper changed first?" Dash continued, glancing over at Applejack knowingly.

Applejack had never felt more embarrassed in her life than she did at this moment, forced to waddle through the dead center of the Ponyville market, wearing a diaper and ready to burst. Rarity trotted right alongside her and had been staring straight ahead ever since they entered the town, her muzzle growing redder and redder with each confused pony that they passed.

Rainbow Dash led them through the market with a constant cocky grin, parading them behind her. As they got to the more dense parts of town, they were met with mostly confused looks, though there were a few suppressed giggles and even a few blushes here and there. Though none knew what was really going on, most correctly assumed that this had to be the result of some kind of bet being lost. With Dash at the helm, it was a safe assumption to make.

It didn't help that Applejack had been practically stumbling as she constantly fought to keep her rear legs pinned as close together as she possibly could.

"R-rainbow Dash, how much longer are we gonna be out here," Applejack asked, practically shaking as she struggled to keep her almost bursting bladder from making this any more humiliating.

Rainbow didn't respond, merely wandering up to the one stand she'd come all the way out here for. Granted, she'd decided to take the scenic route.

"Hey there Clover" She called out to a mare ducked down behind the stand. A dark green maned mare with a lighter green coat poked her head up over the counter, the corner's over her mouth turning up as she saw the three of them approach.

"Ah, Rainbow Dash, I see you've brought two adorable little foals with you~" She giggled, looking over at AJ and Dash with a knowing smile that caused both of them to blush.

"Yep, told ya I'd happen one of these days." Rainbow laughed.

"Well, they are a pair of cuties~. So, what brings you all the way out here today?"

"Lookin for some 'lunch', if you know what I mean," Rainbow replied ominously.

"Ohh~? Really? Takin it that far, huh? Well, I'm sure they'll love the surprise." Clover giggled.

'Why do I get the feeling I'm not gonna like whatever this is...' Applejack thought, gritting her teeth as the pressure in her bladder was becoming almost unbearable. As much as she hated to admit it, there was no way she'd be able to last until the end of the day like this. But she refused to wet herself out here, while everypony in town was watching.

"Well, that'll be 2 bits then," Clover replied, reaching down and fetching a case of small bottles from behind the stand. Each bottle was filled with some kind of milky white substance. Rainbow gave the mare the bits before stuffing all the bottles down into one of her saddlebags.

"R-rainbow..." She suddenly heard Applejack whisper, voice strained. This drew both her and the shop pony's attention. The padded farmpony was blushing intensely as her whole body looked like it trembling. "I r-really gotta g-go. P-please, can we g-go now?" She begged, her hind legs narrowly touching each other as she was barely holding her bursting bladder at bay.

"Not just yet 'little one', we've got one more stop before we can go back home," Rainbow explained, pretending not to notice how desperate the mare was. "Why don't you just relax?"

"R-rainbow Dash, if we don't g-go now, I'm gonna- I'm- I-i c-can't-!" Applejack sharply gasped mid-sentence, her head shooting up and eyes widening in alarm as she felt the dam finally give way.

*Pssshhh!*

Applejack was left frozen in shock as she was no longer able to hold her bladder for any longer. Staring straight ahead with burning cheeks, she didn't dare look at anypony as a mighty torrent of piss began flooding from her marehood. Though she couldn't see it, she could feel the padding around her flanks expanding as it absorbed her urine, widening her gait little by little. She almost couldn't believe this was actually happening. She was really wetting a diaper in the middle of town, right in front of everypony.

Rarity watched Applejack's diaper swelling from beside her, a hoof held up over her mouth as she could almost feel the intense embarrassment practically radiating off of the country mare. Though, even as AJ was soaking her diaper, Rarity couldn't help but feel strangely... jealous?

Clover could be heard muffling a fit of giggles as the constant splatter of liquid against padding slowly but surely came to end. Though even as Applejack finished, she did not move another muscle. However, while this was initially due to the intense shame she was feeling, the immense sense of relief that washed through her body was truly something else.

"Feeling better now, hmm?" Rainbow asked, giving Applejack's soaked diaper a playful pat with one of her wings and finally startling Applejack from her trance as she felt the soaked padding press up against her rear. "Now, come along you two, the faster we get this last chore done, the sooner we can go home so I can get you changed~."

With that, Rainbow casually waved to Clover before turning and guiding the two padded ponies towards their next destination. Throughout all of this, Rarity remained speechless. It wasn't until she noticed an odd twitch in each of Applejack's steps that she spoke.

"So, um, A-applejack, how are we feeling?" Rarity whispered as she walked alongside, stealing a glance back at her soaked diaper.

"I-im... Im fine," Applejack answered, stuttering for a moment during one of her wider steps.

"So, ah, It wasn't so bad after all, r-right? I-im mean sure, a few ponies can see us wearing these diapers... and you using yours, but I'm certain that this could be far worse!" Rarity laughed anxiously, trying to assure herself just as much as Applejack.

Applejack remained silent as they made their way towards another stall at the other end of the market. As they made their way around town, slowly but surely the many baffled eyes that had been staring at them all this time started to dwindle. Though some, specifically those who had been blushing beforehand, were still watching attentively...

"Ahhh, home sweet home." Rainbow Dash let out a content sigh as she hovered through the front door of her cloud home, followed by two padded ponies that waddled closed behind her. "Now, you two can go play in your playpen for a little bit while I fix you up some dinner!"

With that, the pegasus darted into her kitchen, disappearing from sight along with her saddlebags. Without saying a word, Applejack waddled into Rainbow's bedroom. Rarity followed anxiously as they approached their playpen. Ever since they'd left town, the AJ had been acting surprisingly calm and nonchalant about what happened.

Rarity had been expecting her to demand that Rainbow change her soaked diaper the moment they got back, but now she seemed to no longer really mind the wet padding taped around her flanks.

"So, ah, feeling better I assume, Applejack?" Rarity inquired curiously.

"I... I guess so." Applejack mumbled, tilting her head down. "It... it wasn't quite as bad as I was expectin anyways..."

"Well, that's wonderful..." Rarity replied optimistically, leaving the two in awkward silence as they found their way back inside Rainbow's special playpen. "Though, from what I recall the, ah, wet texture did feel rather strange after my a-accident." She continued, searching Applejack's blank expression for any hint as to what she might be thinking.

"Yea... it does..." She eventually replied, face blank as she was deep in thought.

"Alright you two, after you finish your dinner, it'll be about time for your naps," Rainbow announced, entering the room while carrying both of their milk bottles from earlier, now refilled with milk and surprisingly appetizing to look at. "Here, have one more bottle before bed while I go set up your crib~." She continued, handing them their baby bottles.

Remembering how good the milk had tasted before, Rarity eagerly grabbed the bottle, practically shoving the nipple into her muzzle as she downed the delicious concoction. It was just as good as before, maybe even better. Though... she couldn't quite shake the feeling that there was something slightly off about it at the same time. Applejack glanced up at her and sighed again before starting to drink from her own bottle.

The two watched as Rainbow Dash opened up her closet and started pulling out the pieces of what eventually became the biggest crib either of them had ever seen. Almost as big as Rainbow's own bed, it could easily fit two ponies comfortably. It had never really occurred to Rarity until now that they'd be sleeping in a literal crib, though, it was hardly worse than anything else they'd done today.

"Alright, done, have you two finished your milkies?" Rainbow cooed, hovering over to them.

Much to both Rarity and AJ's surprise, they had actually just finished draining her bottles only a few moments ago and had been just absentmindedly suckling on the tip ever since.

With two mutual nods, Rainbow swooped over and hefted the two adult foals into their crib. Sinking down into the mattress which was decorated colorfully with fairies and tiny baby ponies, Rarity couldn't help but feel safe and surprisingly cozy. Looking over at Applejack, she found the farmpony wearing a conflicted expression as she sat in her wet diaper. Rarity's eyes eventually drifted down to the soaked padding, biting her bottom lip a little as she squirmed in her own dry diaper.

Rainbow Dash flew over to the stack of books that she'd been looking through earlier. Apparently deciding on one of them, she returned, smiling as she opened the colorful cardboard book to its first page.

"Alright, you two ready for your bedtime story?" She asked.

They both nodded, both feeling surprisingly eager to hear it. So much so that neither of them even noticed the subtle rumbling coming from their stomachs as the milk's secret ingredient began to take effect...

As the story was progressing, Applejack found herself starting to slowly rock back and forth, squishing and rubbing her wet diaper against herself. She wasn't sure when it started, but as much as she hated to admit it, she was really starting to enjoy the way the urine-soaked padding felt against her flanks. Her cheeks blushed a little as a tingly warmth was blossoming from the constant stimulation.

Rainbow's chosen story was that of two brave mares who were on a quest to rescue a stranded princess from the depths of an evil castle, a classic fairytale-type plot it seemed at first. Well, there were a few fairly significant differences. Namely, the fact that not only did the two main characters 'happen' to share very similar names to their own, but they also wore diapers. Applejack continued to roll her hips in place as Rainbow read, listening attentively as the two mares entered the grand evil castle.

"But then, just as Raret turned the corner, she was met with a terrible, terrifying sight!" Rainbow proclaimed dramatically, actually managing to startle a gasp from Rarity who at this point was fully invested. "It was a ferocious dragon! With long spikey spines all over its scaley body and razor-sharp teeth that could tear a cute little pony like Raret to pieces if it got its long claws around her." She read, occasionally looking up at Rarity.

As Rainbow continued to describe the fire-breathing beast in more gruesome detail as it turned to look at 'Raret', Applejack suddenly picked up on a familiar sound. Looking over at Rarity she found the mare with a fear-stricken look on her face, mouth hanging open as a telltale hissing emanated from within her diaper. Applejack blushed as she watched her friend wetting her diaper for the second time today, suddenly reminded of the immense relief she herself had felt when doing the same at the market. She started rocking a little faster, suppressing a little gasp as she felt a small tingle of pleasure jolt up as the padding worked its way between her flanks.

As the story progressed, 'Raret' and 'Appel' battled the dragon, with Rarity's favorite character also wetting herself not long after she herself had. Applejack couldn't help but be drawn in by the action, eyes widening as Rainbow described the dragon turning its sights on Appel.

"The beast glared down at the small diapered pony, grinning and showing off its many rows of sharp teeth. Darting forward before she could dodge, it seized Appel in its clutches, squeezing her tightly with its long claws."

Despite this all being just a story, Applejack was surprised at how fast her heart was beating, so much so that she didn't even notice as the tightness she imaged started to manifest in her bowels. As the beast tightened it's grip, even more, Applejack suddenly felt the immense pressure pushing from within her rectum that almost went unnoticed. Though part of her wanted to interrupt Rainbow's story and demand that she be allowed to use the bathroom, she knew all to well what her answer would be.

Hearing a quiet gasp, Applejack glanced over at Rarity who seemed to share a similarly urgent look upon feeling a similar sensation. Her legs were tensed up, a sigh that she was also struggling to hold her waste at bay. Wetting her diaper was one thing, messing herself, on the other hoof, seemed to be something Rarity wasn't quite ready for.

Applejack, however, was actually... not too against just letting it happen. Sure, it would probably feel pretty gross, messy, and certainly pretty embarrassing, but... what if it made her feel even better? She hadn't been expecting her wet diaper to feel good at all, yet now most definitely did.

Still feeling a bit cautious, Applejack gently started to ease the tension she'd instinctively been holding on her anus, blushing profusely as she felt the mushy substance trapped inside her rectum take advantage of every inch she gave it. Biting her lip, she looked up at Rainbow, only to receive a subtle knowing nod as she continued describing the tightness of the dragon's hold on her. Letting out one final anxious sigh, loud enough to garner Rarity's attention, she fully relaxed her lower body.

Immediately there was a rush of semi-solid ooze pushing through her anus, leading the flow to slam into the inside of her wet diaper. Still sitting down, Applejack's diaper didn't budge much at first as copious amounts of messy brown goop began filling every empty space and crevice within the padding.

'Im actually doin it.' She thought, her breathing quickening.

Pleasure rippled through her body as she continued pooping in her diaper, intensifying as the warm sticky muck covered her marehood with a layer of slick muck. Though usually she'd be appalled to feel something so dirty touching her like this, now it was enough to force a low moan from her lips.

Rolling her hips back and forth eagerly in an effort to further the feeling, she made an effort to spread the mess around as much as possible. Her cheeks brightened as she could no longer hold herself back, reaching down to press one of her hooves down into her soaked and now quite clearly messy padding. Taking on a brownish hue and starting to really bulge beneath her tail, there was no hiding it.

Rarity watched with a slack-jawed expression as the farmpony began to pleasure herself while still unleashing her bowels, only to suddenly realize how hot she was feeling. Truth be told, she had been feeling a bit 'intimate' ever since re-wetting her own diaper, but seeing Applejack like this was taking it to a whole new level.

"Finally, the dragon released Appel, dropping her back on the ground as a flustered mess of poop and pleasure." Rainbow continued reading, though it was pretty clear she was not actually going by the book anymore at this point. "With the earth pony sitting in a pile of her own poop, the dragon turned to Raret next."

Rarity gulped as she imagined a massive scaley beast towering over her, it's jaws brimming with dagger-like teeth as it licked its maw.

"O-oh m-my" She stammered, an almost real sense of fear manifesting in her mind at the thought.

It was just enough to momentarily loosen her control, only to shake her out of it just in time to pinch off the first few inches of a soft log that took the opportunity to start slithering out into her diaper. Her breath hitched as she felt the chunk squish between her cheeks, spreading across the interior of her padding.

"I-i just..." She gasped quietly.

Blushing intensely, she tilted her head down in shame. She wasn't sure she liked how much she enjoyed the way the gooey chunk felt mashed between her flanks.

'I suppose there's no point in holding back now is there?' She thought, steeling her nerves as she hesitantly started to release her hold over her anus.

Much like Applejack, she was startled by the suddenness of the resulting mudslide. While the first part of her bowel movement had been relatively solid, almost pure goopy diarrhea poured out behind it. Immediately the inside of her diaper was filled with the filthy much, no doubt staining her pristine coat and sullying her privates with a thick layer of poop.

And though she was appalled at how gross it felt initially, her disgust was quickly replaced by pleasure as she felt her soaked and messy padding rub up against her vulva. She gasped loudly and her leg twitched from the unexpected jolt of pleasure, causing her to lose her balance and fall back. A shiver ran up her spine as the mess in her diaper shifted as she rolled back, pushing the mess further up through her butt crack until she felt it gush around the dock of her tail.

"R-rarity!" She heard Applejack gasp, turning to see the mare staring down with wide eyes at her bulging diaper, her hoof digging down between her hind legs and stroking at a rapid pace.

"A-applejack!" Rarity cried, unable to keep herself from doing the same.

Both got so caught up in their messy diapers that neither noticed as Rainbow was pleasuring herself a little as well, cheeks blushing warmly as she continued reading the book out of one hoof.

"But suddenly, as he breathed in to deliver a plume of flame, the dragon gasped and coughed, having inhaled the noxious fumes from the two mare's full poopy diapers. Not able to stand the stinky stench, he took to the air and fled the castle!" Rainbow declared, finching as she rubbed a hoof of her own between her hind legs.

Though at this point, neither of the two padded ponies were listening to the story, currently overwhelmed with ecstasy as they masturbated through their messy diapers.

"A-applejack, I-im about to-" Rarity panted breathlessly, her back arching.

"M-me too!" The farmpony grunted, gasping as she felt one last little squishy chunk of poop get squeezed out from her filthy anus to join the mess already inside her diaper.

"Y-you naughty little foals~!" Rainbow grunted from just outside the crib, her hoof's strokes speeding up as all three of them raced towards a peak.

"Gaahh!!!" They all cried out together, legs twitching and marehoods gushing as they all came together.

They rode the enormous pleasure high hard, lasting for what felt like almost a minute before finally going limp. Breathing heavily, Rainbow slowly looked up, her inner thighs soaked with her juices. Ears perking up, she smiled upon detecting the sound of tiny snores coming from within the crib. Both Rarity and Applejack lay cuddled up to each other, sleeping soundly from their post-climax bliss.

'Oh yes, we will so be doing this again' She thought, confident that she wouldn't need to win a bet for it next time~.
