Pinkie's Fun

Author's Note

This first chapter is a revised version of a previous stand-alone story. It has been edited so that the characters are ponies instead of anthro in addition to a number of changes to the story text, though the overall narrative remains the same.

Pinkie's Fun

The soothingly rhythmical clatter of the Canterlot Express steadily making its way down out of the mountains and into the Celestial valley towards Ponyville was usually something that tended to lull Rarity into a pleasant, though typically brief, sleep. Especially if on days like today when she was returning more toward evening after a long and exhausting trip full of business deals and arranging her appointments as one of the single most favored and trusted of royal courtesans.

Tiring though these activities may be, there was a reason Rarity was now able to afford having her own private train car on these increasingly more common excursions to and from the capitol. There was a time, now several years gone, when she had bemoaned the cost of a single spot on a bench in the standard passenger cars. The jostling and stress of the journey never seemed to do any favors for her carefully maintained outfits or fur. Now though, she thought little of paying a hundred times as much for a bit of privacy, quiet, and most importantly, a personal rail car with better quality suspension.

Looking up from her consideration of one of her many personal clothing sketchbooks, this one featuring ideas for a new line of thong underwear, Rarity smiled at the orange glow of the setting sun, now just sinking below the snowcapped jagged ridges of the Western Ranges. The warm light playfully interacting in unexpected ways with the reflective ice and dark rocks of the pinnacles to form quite dramatic shadows in chasms and glinting surfaces from the sheer walls soaring up into the thin clouds about their summits.

Mentally returning to her immediate surroundings, Rarity turned her head to regard the oh-so-convenient private bathroom of her rail car, its walls made of finely polished hardwood panels, just the same as all the rest of the interior. She considered, not for the first time, how much extra the additional luxury of her own bathroom added onto the price she paid at least once a week for the use of this car. She smiled slightly at the irony of repeatedly paying for something she never seemed to use. After all, on these trips she usually had a thick diaper taped tightly between her legs that was even more convenient and, to be honest with herself, far more enjoyable to use. Of course, simply wearing a diaper was for more than the fun of it. No, she had practical reasons as well. After all, the diapers she regularly wore were of her own design, and Rarity felt that it was a borderline sacred commitment on her part that she personally test everything that she sell, whether it be ball gowns or butt plugs. Therefore, whenever she had a new design of diaper in the works, she had to find the time to try it out. The hour-long train ride between Canterlot and Ponyville made for the perfect opportunity to do just that. Not only could she have privacy, but she could try out her newest diaper in just the sort of situation in which many of her customers might well use it. After all, no one had yet seemed to figure out a good way to make using the bathroom on public transportation a relaxing experience without an unfortunate amount of money being required. Her diapers, she hoped, would help solve this problem for many.

This particular train ride was, however, an exception. Rarity was not in fact wearing a diaper at the moment, mostly due to plans she hoped to pursue later on in the night. Though truthfully, the pressure between her legs was beginning to make her wish she was diapered. As much as Rarity longed to simply spread her legs and go where she was, her present outfit made that a difficult prospect. She was currently wearing one of her favorite pairs of black pvc shorts, designed by herself of course. Not only did the smooth and shiny, thick plastic-like material compose the outside of the shorts, but unlike many other, cheaper garments, these had the same material on the inside as well. The tight smooth feeling of the pvc plastic hugging her butt and hips, to say nothing of how it pressed into her pussy and held her long thick dick firmly upright could keep her hard just thinking of it. Despite the shorts being somewhat high-wasted, Rarity was big enough that a good inch of her cock had a habit of sticking past her waistline when she was ‘in the mood’. Her current clothing choices did little to hide this embarrassing side effect of her arousal.

Her choice of outer shirt was a thin translucent, white, nearly sleeveless blouse designed to show off her tank top underneath, a belly-shirt made of the same slick and shiny pvc material as her shorts, and as they really did nothing to hide anything past the top of those shorts, it would make for an awkward situation if she let herself get too hard with many others to see. It wasn’t really as though she was trying to hide the fact that she currently boasted a fine male member in addition to her well looked after natural sex. After all, the clothes she wore never did do much to conceal her typically excited state, it was just that she was not in the habit of trying to push the bounds of public decency too far. Yes, Equestria was a very tolerant nation in such respects, but there were limits, especially where male sex organs were involved. However, as Rarity was arriving home at a time when most ponies had already returned home, she was not overly concerned.

‘Perhaps just a little piss…a small trickle won’t hurt.’ Rarity thought, as, inevitably, she grew more excited at the idea of wetting in such a hot outfit. The sudden short burst of hot urine from her pussy, (oddly enough she could choose which sex organ her pee came out of) made her giggle for just a second as it immediately pooled between her butt cheeks as it found little fabric to absorb into. For some reason, this wetness made Rarity even more aware of the tight, thin strap of shiny blue fabric her t-back thong was made from. She loved how its tightness made the thong pull up along her butt as she walked. Sexy clothing was about so much more than just how they looked. It had to feel amazing as well. A good outfit could make Rarity horny with her eyes closed.

She dared not pee any more, as if she did it would all run right down her legs the moment she stood up, and make for a hard to explain mess on the floor. Plus, Celestia only knew what it would do to the expensive varnish on the wood. No, Rarity would just have to wait to do what she wanted in her smooth, shiny shorts.

The distraction of the warm dampness under her butt was interrupted by the realization that the train was beginning to slow and the lights of the station were becoming visible from just out of sight. Shaking her head to get herself fully back to the present situation, Rarity hopped up, and began collecting and packing her things into her small wheeled suitcase. Once upon a time she had liked to travel with a much larger bag, as she preferred to maximize outfit options at her destination, but improved common sense and her business and apartment location in Canterlot had released her of that burden. A bit of swift work with her horn had her sketchbook, notebook, and various pencils and pens stacked neatly on top of a white hoodie which she had learned was useful in the cooler mountain summers of the capitol. Under that were two emergency diapers, which could either be used for on-the-spot demonstrations for potential customers, or for her own pleasure if she suddenly found herself craving a diaper between her legs. Under the diapers was hidden a balled up double-strap v-string thong that Rarity had dug out of Sweetie Belle’s dirty clothes pile before going on her trip. Rarity loved to go to sleep with the comforting smell of her little sister by holding her thong up next to her face when going to bed. Though of course she first liked to rub it over her hard dick until she came.

Rarity stood next to the window of her private car as the train pulled up alongside the station platform. As this car was the second to last of the train, in font of only the caboose, where it finally pulled up was at the far northern end of the station where the lighting was dim and, hopefully, few others would get out.

Rarity was a bit surprised, though happily so, to see that there were not one but two mares waiting to greet her. There was her twelve-year-old sister Sweetie Belle standing there, looking to Rarity like an angel in the dim light, wearing tight light blue denim short-shorts with a clear plastic belt and nothing else. Apparently, Rarity was glad to see, her lessons on only wearing one item of clothing at a time to help focus attention to it even more had sunk in. Sweetie Belle’s curly violet and pink mane was brushed well and tied back into a ponytail, a new style of hers, and the short white spike of her horn jutted from the top of her forehead added to the look. All this Rarity noted in an instant thanks to her years as a fashion designer and general expert on her little sister.

Equally scrutinized was the larger mare with long wavy, almost curly bright pink hair standing, Rarity was quick to note, very close next to her sister. Pinkie Pie was wearing a light green skirt of some material that shimmered slightly in the light of the nearby platform lamps. This was unusual as Pinkie Pie, like most ponies didn't typically wear anything when out and about. Though it didn't take Rarity long to determine the cause of this unusual behavior. The tell-tail bulge of a thick diaper, while partially concealed by the skirt was nonetheless noticeable, and even if it hadn’t been the half inch of white plastic poking past the skirt’s waistband would have given up the game.

“Hmm… Pinkie in a diaper…again… I’ll have to ask her about this new habit of hers.” Rarity mumbled out loud to herself, smiling.

As soon as the train came to a stop Rarity was on her way out the door. When she had first began to use this luxury service the station had thought to have a personal greeter meet her on the platform as soon as she got off every time, after all, the Canterlot elite always demanded as much, someone had to be there to attend to all their ‘needs’. Rarity had swiftly put an end to that nonsense, she did not like to be carefully watched over by strangers when greeting her sister on the platform. Besides, she was not a needy little poof from the capitol who didn't know a diaper from a dish rag. She very much preferred her independence, thank you very much.

Rarity hadn’t managed three paces across the wooden planks of the station platform before the sound of a filly running and a flurry of violet fur ended with being glommed onto by Sweetie Belle who threw her forelegs about her neck as Rarity nuzzled her back forcefully. In sum, this was admittedly a rather overly dramatic hug as they had only been apart for a day and a half, yet it was a fun little tradition between the two of them nonetheless.

“Hehe, I missed you…” Rarity said as her sister lowered herself back to the platform while the two of them touched horns.

“Missed you too! Was it a fun trip? Better than last time?” Sweetie asked staring up at her sister with those beautiful wide violet eyes.

“Oh yes, much better! More time with the Princesses, less time with the nobles. Plus, I got to finalize a few important business deals. I might buy you something special in celebration. What do you say to that?” Rarity asked Sweetie Belle who was still pressed up next to her.

“Really! Like what?” Sweetie asked with all the unabashed excitement of a filly half her age.

“Patience sis,” Rarity said smiling, “You’ll get to see, I’ll come up with something, something…exciting.”

As Rarity spoke, her right foreleg pressed gently but firmly against Sweetie Belle’s butt cheek through her tight shorts. Rarity felt her already stiff cock grow even more firm and begin to slide above her waist line. Rubbing her sister’s butt was one of Rarity’s favorite secret pass times and never failed to excite her.

As Rarity held her sister against her and gently rubbed her leg against Sweetie’s butt she looked up to see Pinkie Pie still standing there only a few meters away smiling happily and perhaps a tad lustily at the pair of them. Rarity gave her a wink, which Pinkie returned with a little giggle.

As Rarity looked back down a sudden realization struck her.

“Sweetie dear, I don't recognize these shorts you’re wearing, or rather I do, but not from you. These are Applebloom’s aren't they.” Rarity stated more than she asked.

Rarity never missed an opportunity to watch Sweetie Belle and her friends if she could help it. Though most days the three of them didn't wear clothing at all, they were getting to that age when young fillies started to realize that certain types of clothing attracted attention to certain parts of the body. Applebloom with her sexy daisy duke short shorts, Scootaloo every now and again with tight denim overalls and her own sister often in very short denim skirts were enough to make her hard within seconds. Even better were the days when Scootaloo would show up with a diaper on under those little overalls. Rarity knew whenever she saw that, that Scootaloo had been with Rainbow Dash earlier in the day as putting the purple maned filly in diapers was one of Rainbow’s ‘things’ she liked to do with Scootaloo when they had their ‘fun’. Over time, Rarity had made a rather complete mental encyclopedia of all the various items of clothing the three fillys wore. Sweetie Belle was obviously much easier to figure out than the other two due to living under the same roof.
Therefore, it was not surprising that Rarity had not taken long in figuring out that the shorts now gracing the cute butt of the filly wearing them, while similar to several pairs that she herself owned, were not actually hers.

“Um…yah, A.B. let me borrow them yesterday. She said she wanted to see how I looked in them. She said I looked real nice and wanted me to stay in them for the rest of the day… I guess I never took them off.” Sweetie said while looking down, and though Rarity couldn’t see it, blushing as well.

“You said this was yesterday and you never took them off? Did you sleep in them?” Rarity said smiling all the more.

“Kinda…” Sweetie said reluctantly.

Rarity took the opportunity of her sister’s embarrassed silence to change from rubbing Sweetie’s butt to running her hoof down the back seam of her shorts between her butt cheeks and between her legs. Rarity hadn’t gone far before her hoof began to encounter a dampness in the denim. Instead of stopping, Rarity went on further and began to press the end of her hoof upward. The area of moisture encountered was too big to be simply from a wet pussy, especially at Sweetie Belle’s age, no, this was from pee. Lifting her hoof to her nose confirmed what Rarity had already known. Her little sister had wet in her friend’s borrowed shorts, and from the relative lack of moisture and smell, she had done so some hours before and yet chose to stay in the wet shorts anyway.

“Well, aren't you a brave filly, not only did you wet in your friend’s shorts, but you did so knowing there was a good chance your sister would find out. I’m actually rather proud of you, it’s good to know what excites you and to not be embarrassed by it, don't you agree?” Rarity said looking down at her little sis while smoothing the fur around her ears.

“Thanks Rarity, um, actually I was going to change before coming here but Pinkie said I should stay in them…so yah. I did.” Sweetie said trying her best to sound confidant.

“That’s very good advice on Pinkie’s part, you should thank her for it. Though I have to ask, what were the two of you up to earlier then?”

An uncomfortable silence from Sweetie followed that question and when Rarity looked up at Pinkie Pie, still standing nearby watching the two of them all she got was a somewhat sheepish smile and a slightly embarrassed look, an uncommon thing from that mare. With one eyebrow raised Rarity looked back down at her sister who, fidgeting slightly, looked like a dog that had knowingly been slightly too aggressive with the newspaper. Instead of increasing her sister’s discomfort Rarity decided she would just get the details out of Pinkie later.

“In that case, I’m sure that whatever it was, you two had fun. Now Sweetie, stand back and turn around and let sis get a good look at thoes shorts. I want to know how well I agree with Applebloom.”

Doing as she was instructed, Sweetie Belle removed herself from Rarity’s side, stood back a step, and turned herself around. The lighting was dimmer than Rarity would have liked but she could see well enough, and in fact the long shadows in some ways helped to enhance Sweetie Belle’s curves. The denim shorts certainly were wonderfully tight, hugging her hips and skinny yet round butt beautifully. The overall look was in fact rather basic. There were no fancy designs, ornamentations, or unnecessary flaps and frills. There weren't even any back pockets at all. Even the seams were smooth and the light blue denim was worn and faded but nowhere torn. In all, they were perfect for showing off a filly’s curves without distracting from the pony herself with their own flashiness. Perfect shorts for a perfect sister. The, by now, mostly dried urine stain covering the crotch of the shorts and migrating a way back up underneath Sweetie Belle’s tail made Rarity’s dick throb. She wanted nothing more right then than to rub it all over Sweetie’s hot twelve-year-old ass until she came.

Collecting herself, Rarity decided that the best way to continue on without exploding was to keep up the conversation.

“I must say, Applebloom sure was right, you look stunning in those shorts. You should be proud of yourself for looking so nice, and be thankful you have friends who know you so well, you’re making me a very happy sister.” Rarity said as she pressed the bulge in her own shorts with a hoof while contemplating Sweetie’s butt.

“Aww, thanks Rarity! I knew you would like them too, they feel so nice to wear. Applebloom is the best!” Sweetie Belle said happily as she thrust her butt out a bit and wiggled it playfully against Rarity’s left foreleg. Rarity closed her eyes and took a deep breath, promising herself that before the night was through she would have a ‘discussion’ with her little sister about the consequences of teasing her so. Unfortunately, that would have to wait.

“Mmm…that makes your sis feel very good, you know that, don’t you?” Rarity asked bending over Sweetie Belle to whisper in her ear. At the same time she put her hoof up on Sweetie’s hip over where her cutie mark would one day appear as she gently began rubbing her stiff shaft with the other front hoof, sitting back on her back legs as the only way to maintain balance.

“I know you like how this feels too but we need to wait until later if you want to keep having fun. Also, we are keeping Pinkie waiting, which isn’t very nice now is it?” Rarity said, being aware of even her own hypocrisy as she was the one doing the rubbing.

“Ok, ok, I know, but you’re the one who- “

“Yes, I know sis, I’m sorry, I should be better at controlling myself in public, shouldn't I?” Rarity said to Sweetie Belle giving the filly one last forceful push in the butt as a response to Sweetie’s halfheartedly suppressed laugh.

Reluctantly releasing Sweetie Belle, Rarity strode the few quick steps to Pinkie Pie and gave her a light hug. This was immediately returned by another hug from pinkie with about five time the strength, nearly enough to pick Rarity off the ground entirely.

“Ooo! I Missed you so! Lest celebrate your return with-“

“No need Pinkie! Whatever it is, it won’t be necessary.” Rarity said cutting her off. She had enough ‘parties’ to attend the way it was; she was not enthusiastic about the prospect of even more.

“Oh, all right silly!” Pinkie said as she released Rarity from the bear hug.

“Though I’m sure there is something you would like to do, considering the outfit you’re in.” Pinkie said with a hot smile as she slid an oddly dexterous hoof under Rarity and over the still firm shaft of Rarity’s cock through her pvc short-shorts.

Shuddering slightly and considering that as much as Rarity liked where this was going she had to do something to intervene.

“Really Pinkie, not here!” Rarity said making a show of looking around. Nopony seemed to still be anywhere near anymore, but anyone could wander by at any time.

“I think it’s time that we headed home. I have no intentions of staying at this station forever. Come, Sweetie, let’s get going” Rarity called back to her sister.

On their way out of the station, the station master made a small show of bowing to Rarity when he saw her from the windows of the office and coming out to thank her for her continued patronage of the Ponyville Express. While she graciously accepted the thanks, and promised that she had every intention to continue using the train service, she was just a bit annoyed at the unnecessary attention. All she wanted was a quiet walk home in peace, though admittedly it was always nice to be recognized and appreciated. Fortunately, though, the encounter was brief and within a minute they had left the station well behind.

The three of them walked in silence for a bit. The sun had set, and the deep purples and blues of the oncoming nighttime sky were overhead with the planets and brighter stars just becoming visible. The air was warm and still, and the occasional beetle hummed about its business. Rarity kept close to Sweetie Belle’s side as they walked. The love they shared didn’t always need words to be expressed, they simply enjoyed being next to each other. Pinkie Pie for her part hummed to herself and strode happily just in front, swaying her hips a bit more than was completely necessary Rarity thought. However, it was not Pinkie’s hips strictly speaking that held Rarity’s attention.

The bulge around the pink pony’s hips and butt was made plainly obvious to Rarity thanks to the tight glittery skirt the mare in front of her wore. Perhaps to somepony else it would have not been so immediately recognizable, but Rarity knew what she was looking for. If the bulge were not obvious enough, about a centimeter worth of white plastic stuck up above the waist line of the skirt, and sometimes the thick crotch of a diaper could just be seen below the hem of the skirt, though it was too dark to make out if the color of the diaper had been changed. Pinkie obviously wanted Rarity to see what she was wearing with all the subtlety of an earthquake. Even if Pinkie had been working harder to conceal the diaper, Rarity was sure she would have figured it out from the smell. True, it was not strong, and Rarity had not noticed it until being hugged so forcefully back at the station, but it was there. Walking behind Pinkie, Rarity could pick up on the faint stench of a dirty diaper whenever the breeze blew the right way. It was interesting to watch the pink mare as she walked, Rarity had seen a number of her customers come to her to purchase a new set of diapers while wearing an already wet one themselves. Often, there was a bit of a waddle to their movements, almost a natural reaction to the thick padding between their legs. Pinkie however, showed no sign of caring whatsoever. She walked quite normally, aside from the sexy hip motions, she might have been wearing a thong for all the restriction to her movements she displayed.

Rarity glanced down to her sister trotting alongside to the left. Was she watching too? She must be able to smell Pinkie. Heck, they had probably been together for hours already, she had to know. To her surprise, Rarity caught her sister staring at her, or more specifically at her hip, or butt, it was hard to tell. She could understand why, as she walked, the dim light of the occasional lantern and the whiter light from the rising moon made her slick pvc jeans-style short shorts reflect that light in beautiful undulating ways showing off the roundness of the healthy mare’s body tightly enclosed underneath. Glancing quickly behind to make sure no one was anywhere in sight Rarity spoke quietly to her sister.

“Looks like you are enjoying what you see.” Rarity said, making Sweetie Belle start a bit and then look away apparently embarrassed.

“Don’t be shy now, I’m your sister, not some mare off the street. Here let me help you.”

Rarity halted her walk briefly and hooked one of Sweetie Belle’s legs with her own and lifted it up and behind her. She then placed that hoof firmly on her butt and held it there. After a few seconds of Sweetie holding her hoof in place the two of them resumed walking onward in silence, Pinkie having not seemed to notice her companions momentary pause. Still without a word, Sweetie Belle soon moved to walk even closer to her sister and pressed her cheek up against Rarity’s thigh as they continued walking. Due to the wonderful ability for pvc plastic to easily transfer heat, Rarity could immediately feel the warmth of Sweetie’s cheek on her thigh as it gently bumped against her as she walked. The feeling was subtle, yet so full of enjoyment that Rarity had to keep herself from stopping right there and making out with her lovely little sister. But the quiet sexiness of the situation was a joy to experience in its own right.

It didn’t take more than a minute or two before Rarity saw out of the corner of her eye a soft green glow form around Sweetie Belle’s horn and a slight tingling sensation just below her waistline in back. Su re enough, as she had guessed she would, she felt the magical pull hook onto the back of her thong just where the straps made a ‘T’. Just a few small tugs made Rarity shiver and she looked down ruefully as she heard a small giggle. She paused in her trot once more and reached her front right leg around Sweetie Belle’s shoulder and hugged her close to her side as the inquisitive magic went back to roaming over her butt. Rarity couldn’t help but briefly muse on the fact that her little sister got to do for free what many mares in Canterlot and a few other cities paid hoovesomely for.

Lost in their mutual fun, Rarity was almost surprised when she suddenly realized that they were getting quite close to Carousel Boutique, the original home of Rarity’s expanding business empire, having walked nearly all the way across Ponyville, not that such a walk was a particularly long one however, as Ponyville was still lost somewhere in that nebulous realm between being regarded as a large village or as a small town.

Rarity also realized that Pinkie was still with them, having led them the whole way. Apparently, they had business to discuss before parting ways she decided. Otherwise the pink pony would have mysteriously vanished somewhere along their route as she had an occasional habit of doing.

“Go on inside Sweetie Belle, Pinkie and I have grown-up stuff to talk about. I’ll be along in just a minute.” Rarity said, detaching herself from her sister.

“Aww… I wanted to watch…” Sweetie Belle said, somewhat under her breath.

A raised eyebrow from Rarity was all the motivation Sweetie Belle needed to do as instructed. Perhaps though, someday, maybe someday soon, she could watch. Rarity considered this, looking on as the small form of her little sister ran up the steps and opened the front door, Rarity smiled with love for the young filly. Soon enough warm light was spilling out from behind the front curtains and onto the porch where the two stood.

“You and I have a thing or two to discuss, Pinkie.” Rarity said with a sly smile.

Pressing her hips up against pinkie’s in a similar movement to what she had recently done with her sister, Rarity led Pinkie around the circular porch of the structure to the back of the boutique and to a back door that led directly into Rarity’s private work room, in which she always kept a light on. Unlocking the outside door for the both of them, Rarity looked inside and noted that she had locked the inner door as well, the one that led into the boutique proper. Out behind them stretched several acres of farm fields and behind those, the dark outline of a forest. That was one of the nice things about living on the edge of town in Rarity’s opinion. Fewer folks to always be watching you.

As soon as the two mares came inside and the bolt on the door was securely fastened, Rarity immediately turned and kissed Pinkie hard, pushing her tongue between the mare’s teeth and licking every crevice she could get to with it. Pinkie of course, happily accepted the intrusion and returned the favor. She also grabbed Rarity’s slick pvc covered butt and squeezed excitedly. Almost as soon as Rarity began she pulled away. And set pinkie with a stern look.

“So what exactly is it that you are wearing under that skirt of yours?” Rarity asked in mock anger.

“I’ve been able to smell it ever since I laid eyes on you this evening.”

“Hehe, they’re my favorite kind of underwear Rarity! Would you like to see? Diapers are the best, most wonderful thing ever! Here, what do you think?” The pink mare asked excitedly.

For a brief second Rarity mused that in this statement Pinkie was, as the saying went, preaching to the choir.

Lifting the back of her skirt, with a foreleg Pinkie treated Rarity to a very naughty sight. A thick disposable diaper, heavily swollen with pee, yet taped tight enough so as to not sag much was covering all of Pinkie’s round butt. The diaper was large enough and Pinkie still slim enough that the padding even wrapped over most of her thighs partially obscuring her cutie marks. It took Rarity no time at all to identify the diaper as one of her own manufacture with its subtle classy design of silver lines running around the leg holes and the front clear plastic tape guard or ‘landing strip’ with its small silver star pattern, along with the light pink of the sides of the diaper, which were designed to accentuate the white front and back. Or rather, a front and back that would have originally been white.

Upon closer inspection, the front was not discolored just by urine but there was actually a slight brown hue to it. The first question to Rarity’s mind was how long had Pinkie been in this diaper and how much had she used it? Without thinking Rarity brought her leg up and pressed a hoof into the thick, soaked and apparently messy padding of the back of the diaper. Feeling the warmth of the diaper combined with the smooth plastic of its surface seemed to send a direct message to Rarity’s member making it stand to attention. Pinkie simply smiled over her shoulder at Rarity’s hoof and wiggled her diapered butt in a non-verbal attempt to get Rarity to move her hoof about more.

“I need to see what’s inside that diaper, Pinkie. In fact, what I really want… is to be inside of that diaper.”

“Oh, Rarity! I thought you’d never ask!” Pinkie said with her customary delight.

“Diapers are the best thing ever! I know I already said that but it’s so true, I love wearing my very own toilet and peeing in it! And pooping in it! And squishing it all over! And they are even better when you get to have sex in them!”

Pinkie continued without pause while already in the process of tugging off her skirt and laying it out on the polished wood floor of the small room. It hardly made for much protection from the hard wood due to its thin material but neither Pinkie nor Rarity were in munch of a mood to care about such trivial matters.

As soon as her skirt was laid out Pinkie Pie sat down heavily on it with an audible squish and a moan of pleasure. Now Rarity was desperate to find out what all Pinkie had done in her diaper to cause such a sound. She began to peel off her tight pvc shorts now that she was sure that whatever was going to happen over the next few minutes her rock-hard shaft was going to require unrestricted motion. Though Rarity couldn’t help feeling slightly disappointed as she peeled off the smooth plastic shorts. She did love how they felt on her. But unfortunately, this was not a ‘have her cake and eat it too’ situation.

Pinkie watched with interest as Rarity’s dick was freed from its confines and bobbed about enticingly. Rarity’s skimpy thong, though doing nothing to contain her shaft did still cover her two heavy, smooth balls, and her dripping clit. As Rarity carefully folded her shorts and laid them carefully on a nearby table (she refused to treat them without respect no matter the situation) she decided to keep her thong on, after all, she liked how it felt running up her butt.

Soon Pinkie began to tug at the tapes holding the diaper firmly in place about her body, but Rarity decided she wanted more control over the situation.

“Here, let me do that, you just lie back and relax, Pinkie, let mommy do the work.”

“Ooo… Ok, ‘mommy’, come check out Pinkie’s messy diaper!” Pinkie said as she lay back onto the floor with her diapered butt positioned directly over the skirt she had laid out

“My pleasure pinkie, I see you have on one of the diapers I gave to you a while back and I want to see how well it has stood up to some obvious heavy use.”

Rarity could have used her horn for such a task, but when it came to diapers she was very much a hoofs-on kind of gal. Sitting down right in front of Pinkie, Rarity first laid both her fore-hooves on the front of the stinky bulging diaper and enjoyed the warm smoothness of the plastic. She was proud to see that even though obvious brown stains had appeared all around the leg holes of the diaper and were creeping up and over the front, there had been little to no leaking. Perhaps there was a bit of poop visible in the fur between Pinkie’s inner thighs and the diaper, but not much. Unable to help herself, Rarity leaned forward and kissed the front of the diaper, reveling in the smell it gave off. This made the mare wearing the filthy thing giggle playfully as she gave Rarity’s head a quick squeeze with her legs.

Slowly pulling on the fastening tapes so as not to damage them in any way Rarity released the front of the diaper and pulled it off of Pinkie letting it plop down heavily in front of her. The sight of most of the diaper, along with the majority of Pinkie that had been under said diaper coated in a slick layer of brown paste that glistened in the lamp light made Rarity grin wickedly. This was even more messy than expected, and she had expected a lot. Furthermore, it occurred to her sensitive nose that the smell from the diaper was perhaps not just from a recent mess but from poop older than only a few hours.

“Oh, my. Pinkie…tell me dear, how long has it been since you changed into this diaper?” Rarity asked. Expecting, and honestly hoping, she was correct in her assumption.

“Umm, let’s see now, I put this one on late on Wednesday night before going to bed.” Pinkie said, making a show of being very thoughtful about it.

‘A day and a half! In the same messy diaper! Pinkie must be immune to diaper rash.’ thought Rarity, somewhat enviously. Though, she considered…had she ever tried staying in a messy diaper quite that long? She decided she had not. Perhaps and experiment was in order.

“And, uh, how many times have you messed it?” Rarity asked while placing her other hoof over the shaft of her cock while staring at the outline of the pink mare’s pussy, now slick with poop.

“Well, I made a big runny poop right after I put it on before going to sleep, then another one after breakfast yesterday, then again last night, and again earlier this afternoon… So four times I guess? And I always made sure to squish it around lots and lots to make room for the next load! That's why I like your diapers so much Rarity! They can hold so much! I’ve lost count of how many times I wet it too,”

Rarity shook her head in amazement. And she thought she stayed in her messy diapers a long time, sometimes most of the day, but here was a pony who was taking things rather further.

And that made her incredibly horny.

“Pinkie, please let me fuck you, please?” Said Rarity almost desperately.

“Silly! What do you think I’m laying here for! Dirty diaper sex is what every filly needs!”

Without even bothering with a verbal reply to such a statement Rarity slid her legs under Pinkie’s, pressed the head of her leaking shaft against the shit smeared pussy before her, and with a single swift movement she was suddenly all the way inside the dirty mare, to the point that her balls were pressed up into the poopy mess coating Pinkie’s crotch, and her own pussy was squished into the messy padding of the diaper below her.

A pair of deep moans sounded out through the walls and into the still night air of the countryside behind the boutique. Articulate comments were hard for either of the mares to express as they worked at adjusting their positions.

“Ohh… Pinkie, how do you stay so delightfully tight?” Asked Rarity as she began to pull herself about halfway out of Pinkie Pie before thrusting herself back in, the warm shit coating her slick shaft making for an excellent lubricant.

“I’m not that tight silly! You’re just so big!” Pinkie said laughing, as Rarity’s thrusts made wet squishing sounds.

“Perhaps I am, but I still think you’re tight anyway, which is amazing considering how often you have things inside of you.”

Pinkie’s response to that statement disappeared in a series of grunts and moans as she lost her desire, or ability, to continue the conversation. Her body was now glistening with sweat as she repeatedly took in the full length of Rarity’s wonderfully large member, the same member that had been granted to Rarity by Princess Cadance and subsequently used on half the mares in Canterlot, if any of the stories were to be believed.

Even Rarity had given up on trying to carry on with the conversation, lost as she was in the feel and sight and certainly the smell of having hot, wet sex with a mare in an overly used diaper. The sensations reminded Rarity vividly of her experiences being babysat as a young filly by a teenage mare who thought it fun to let Rarity simply stay in her diapers, which she wore until she had been almost nine, long after she had both wet and messed in them. Far from trying to be cruel, the babysitter, who’s name Rarity had embarrassingly forgotten, had realized that she liked how her diapers felt when used, and decided to not interfere with the filly’s pleasure. Even going so far as to let young Rarity bounce her poopy butt on the young mare’s back, spreading her mess all over in her diaper. Even today, Rarity still got horny remembering the way the poop felt being squished around between her legs as she ran around her parent’s back yard. She could also remember how the babysitter would occasionally come around and put her hoof on the front or back of Rarity’s diaper and thoroughly feel all over the outside to check if Rarity had used it or not despite knowing full well she had used it some time ago.

None of these memories however, were being consciously recalled as Rarity swiftly headed towards orgasm. It was embarrassing really, how fast she was ready to cum. After all, she was a practiced expert at making sex last precisely as long as she wanted to and not a second less. However, she usually had not just spent the last half hour doing sexy things with her little sister or fucking a mare who had been in a poopy diaper for two days straight. Plain sex was far more easy for her to deal with in terms of still being able to think logically. This situation however, was simply too much to take. Her cock had been desperate ever since she had first saw her sister and Pinkie on the station platform, and since, in Rarity’s opinion, her sister’s body was still too young to take her inside, Pinkie had been the logical eventual partner of the night.

Giving up on her thoughts of trying to control herself, Rarity simply erupted deep inside of Pinkie, her cum a hot gooey torrent, each ejaculation accompanied by groans from both mares and eventually a yell from Pinkie as she herself came, spraying clear fluid all over Rarity’s poop smeared balls. Rarity didn’t let that be an excuse to stop, instead she simply used the new slimy feeling of her own cum, now helping to fill Pinkie, to bring herself to orgasm a second time in as many minutes. Pinkie, for her part, happily went along for the ride, moaning for all she was worth, while Rarity’s deep thrusts repeatedly squished the pink mare’s butt back and forth in the mess of her diaper.

Having finally spent herself, Rarity lowered her body down onto Pinkie Pie, the both of them still breathing heavily.

“So, I’m guessing you liked that.” Rarity said before parting Pinkie’s lips in a short but deep kiss.

“Oh, just a little!” Pinkie said laughing.

“But maybe next time you should be the one in the diaper and I’ll have the cock!”

“That does sound marvelous dear, but you’ll have to ask Cadance or, if you’re brave enough, Luna, if you want a member like mine. I’m afraid I don’t have the magical ‘finesse’ as it were to create my own.” Rarity replied seeming almost disappointed.

“Oh, don’t feel bad Rarity, just be glad you have one to stick inside so many ladies anyway! I don’t care who made it, as long as it fills me up!”

“Stick inside…” Rarity repeated, thrown off her train of thought by the crassness of the comment.

“Well, so much for expecting elegant comments from that one.” Rarity mumbled to herself, though loud enough for Pinkie to hear anyway.

“So um, Rarity, assuming you’ve blown you’re load in me as much as you wanted to… could you tape me back up in my diaper? Please?” The Pink haired mare asked, looking as innocent as it was possible for her to do.

“Really Pinkie?” Rarity asked staring down at the mare under her, watching as a goopy stream of her own white cum seeped out of Pinkie’s pussy and pooled into the brown muck coating the insides of the diaper.

“You still want to stay in that thing?”

“Well of course silly pants! It’s not like its falling apart yet or anything, and it’s not leaking either! Well…very much. Anyway, the more I use it the better it feels.” Pinkie stated quite matter-of-factly.

Shaking her head, Rarity sighed and, again, preferring to use her hooves for such things, lifted the front of the diaper, which she found to be surprisingly heavy, and folded it over back onto the mare lying on it. Pinkie groaned and wiggled herself around a bit as the now cooled squishy mess came back into contact with her crotch and lower stomach. Rarity made it a point to pull the tapes as tight as she thought the diaper could take. After all, if Pinkie was going to keep on wearing the filthy thing, then it might as well be taped up right.

“Pinkie! Hold still.” Rarity admonished as the diapered filly wriggled her hips about trying to get as much sensation as possible from her movements as the messy diaper was pulled up tight around her.

“Sorry Rarity, it just feels so good on me, especially feeling all your cum mixed in with my mess!”

Sighing, Rarity admitted to herself that Pinkie’s actions, despite being frustrating at times, and, no doubt her words, were making her get hard again.

‘Too late for a third time, I need to get ready for tonight.’ Rarity thought.

“There! All done. Now you can enjoy your, ah, old and extra dirty diaper…again.” Rarity said somewhat dryly. As she finished getting Pinkie back in her quite well used padding.

“Oh, thank you so much Rarity! I feel great inside and out now, thanks to all your cum squishing around deep inside my pussy!” Pinkie said standing up and stretching.

Rarity had to admit that the way the diaper’s smooth plastic wrinkled around the tight tapes and the way the discolored diaper bulged out so full of pee and mess really was rather enticing. It was a sign of how well the diaper fit Pinkie no matter how thoroughly it had been used.

“But I gotta get going, it’s about bedtime for the twins now and they always sleep better when they can sleep with me.”

“Don’t tell me you’re going to sleep with those two while wearing that thing. Won’t the Cakes be angry? You won’t be setting a good example if the twins’ potty training is supposed to stick.” Rarity said with mild concern.

“Ok, then! I won’t tell you then!” Pinkie said, while a mischievous smile spread over her face.

“Anyway the twins wear diapers at night besides, so they might as well learn to enjoy them, right?” Pinkie continued.

“Just…don't do anything too, I don’t know…dirty, with them.” Rarity said, wondering at the double meaning in her own statement.

“Rarity!” Pinkie exclaimed in mock offense.

“I’m the most trustworthy and diaper-experienced mare you could hope for!” I’m perfect for the job!”

“Of course you are Pinkie.” Rarity said, smiling, white doing everything she could think of to not roll her eyes.

“Thanks again Rarity, you’re the best! And next time…” Pinkie said taking one of Rarity’s hooves and pressing it firmly against the back of her diaper, which made a wet squelching sound, while reaching out her own hoof and firmly taking hold of Rarity’s still exposed and still quite stiff dick.

“I want you up inside my butt as far as you can go while I try to poop at the same time. I want to see if I can still use the bathroom during anal sex. Have always been curious ‘bout that!” Pinkie said, suddenly shifting from sounding sexy to her more typical, bubbly personality.

“Bye now!” Pinkie said, quickly turning and heading out the same back entrance they had come in only minutes before while at the same time pulling on her skirt.

Rarity, suddenly standing alone in her private work room could only shake her head at the amazing, though so very odd friends she had made over the years.

As she strode over to retrieve her shorts from the counter she had placed them on, Rarity was suddenly struck with the realization that she had to pee, and quite badly at that.

‘Damn, of course I’d only have to pee after Pinkie left. If that crazy pony had only stayed two minutes longer I could have gone in her diaper or even insider her…’ Rarity contemplated.

‘Ah well, no use thinking on it now…’ Rarity decided, somewhat frustrated.

Leaving her workroom, now with windows open to let it recover from the stench of Pinkie’s diaper, Rarity quietly padded barefoot through the darkness of her boutique. The mess she had acquired from the diaper of the mare she had just fucked formed a thin slick layer over her cock and between her legs, which she found herself quite enjoying as the night was a tad muggy and the wetness between her legs was helping her cool off. As she turned and was about to ascend the stairs up to her private rooms on the second floor of the circular structure the silhouette of a still, curved form laying on the sofa under the far window caught her eye. Pausing, then changing direction towards the sofa, Rarity, on silent feet, went to investigate. The soft silver moonlight through the window reveled the sleeping form of Sweetie Belle. She was lying on her side, with her legs tucked in next to her. The filly must really have been tired to have gone to sleep so quickly after getting back despite her knowing, to some degree, what her older sister and Pinkie were up to. Her eyes slightly damp from gazing down upon the innocent beauty of her little sister, Rarity was quick to realize that the filly was still wearing the same faded jeans shorts that she had been in all evening. Apparently being wet in her friend’s shorts was just as pleasant of a thing to do while sleeping as it was while being awake.

“What’s this?” Rarity quietly asked herself, leaning over her sister. The moonlight, while dim, did a good job of showing Sweetie’s skinny, but nicely rounded butt being hugged tightly by Applebloom’s shorts. Now however, there was much more than a faint damp patch between her legs. Half of her butt was darker than the other half, having been recently wetted, with the filly’s urine no doubt. Rarity, intrigued, considered this a moment. If Sweetie Belle had wet them while laying on her side, that would account for the uneven dampness, meaning she had peed after laying down.

“I wonder if she wet on purpose or legitimately ‘wet the bed’ so to speak?” Rarity mumbled to herself, considering the implications. Either way the sight before her, while adorable, somehow made Rarity’s member stand to attention once again.

Along with her newly returned sexual vigor, Rarity was also painfully reminded of her need to urinate and soon. Returning her stare to her little sister and noting the thick clear plastic sheet protecting the sofa from just this sort of occurrence, a wide smile split the mare’s face. Rarity was a mare that liked projects and chores to be completed fully and without parts left undone. Therefore, while seeing half of Sweetie Belle’s butt newly soaked with pee was a very adorably sexual thing for Rarity, it was also somewhat frustrating. It seemed a job incomplete somehow.

Fortunately, Rarity had just what she needed to complete the task, and if Sweetie Belle did wake up because of it, Rarity doubted very much the filly would mind.

Positioning herself properly, Rarity held her now quite hard shaft over her sister and aimed it at the part of Sweetie’s butt that was more or less dry. She leaned over her little sister to get the head of her cock only inches from the smooth denim-covered butt before her. Rarity did not want a long arc of piss that would splatter everywhere and potentially get the walls or floor dirty. She was not in a mood to clean up anything more aside from herself tonight.

Relaxing with a soft sigh, Rarity released her hold on her bladder and let the stream of piss shoot along the length of her cock to spray forcefully onto the cute booty laying just below. The amount of piss in her stream almost immediately soaked Sweetie’s left butt cheek and then began to seep down over her thighs and in between her legs. Soon enough the wetness of her butt was quite equally distributed, much to Rarity’s pride. Despite having accomplished her immediate goal, Rarity wasn’t done pissing and so moved her stream directly to the center of Sweetie’s butt and continued to let it flow for as long as it would.

As her stream finally dribbled to an end, Sweetie’s borrowed shorts glistened in the moonlight from all the pee soaking them. Rarity could also see the small pond of pee that the filly was now laying in. As Sweetie had not apparently awoken from Rarity’s activities, Rarity wondered if the filly would sleep in it all night. Before Rarity recognized she was going it she had her hoof firmly holding onto her shaft and was rubbing up and down along it length.

‘Just like a horny colt’ Rarity thought, bemused at the act of what was effectively simple masturbation. Something that actually she vary rarely ever did as it was not difficult for her to arrange an actual sexual encounter when she found herself horny enough to need release.

Having admitted as much though, the sight before her that had brought her to this sudden strong need to cum, and cum now, was, indeed quite impressively sexy, and worth the private embarrassment.

With humiliating swiftness, Rarity’s slick, sliding hoof caused a thick shower of cum to burst forth and splatter all over Sweetie Belle’s soaked butt, the drops of cum on her upper back sparkling in the moonlight. Sighing, Rarity knelt to gaze at Sweetie Belle’s face in the near darkness.

“You're the best sister anyone could possibly hope for, and I love you so much.” Rarity said quietly to the sleeping filly. After a second, one eye opened just a little to peek out at Rarity.

“Thanks Rarity, You’re awesome too…” A sleepy filly’s voice said.

Rarity, surprised and yet in a way not, at the revelation that the filly was indeed awake if only just, slowly retreated while grinning with both love and amusement.

Before turning and leaving the drenched filly to her wet sleep, Rarity reached out a hoof and gently rubbed the soaked jeans shorts on the butt of the greatest little sister in the world.

Author's Note

These next set of chapters are derived from another stand alone story I only had published for a short time. Unfortunately I needed to take it down and have it edited to comply with FIMFiction story publishing guidelines. I decided to break up the story into sections and make those sections chapters in a larger narrative. The text for these chapters has been edited, like the first chapter, such that the characters are ponies and no longer anthro. Also various other edits have been made to the text. These chapters are written in what I hope is a more "conversation heavy" style so might read a bit different from the first chapter. They are also based loosely on what I remember of a non-pony diaper story I read years ago.

A Look Back pt. 1

*** 3 years before chapter one***

Nine-year-old Scootaloo lay on her stomach atop one of the living room’s large soft cushions reading a comic book, one of the new issues from the Three Worlds series. One hoof is holding the comic book open while the other is under herself pressing against her crotch.

Rarity enjoys seeing the filly’s little round butt in the pair of tight denim overalls Scootaloo is wearing. Though it’s an unusual thing for a filly or even an adult to wear anything at all, Rarity likes to see the fillies she sometimes babysits in cute clothing. Perhaps that way they will grow up to enjoy it just like she does.

Rarity walks by keeping an eye on Scootaloo knowing that the young filly has to pee but is holding it in.

“Why don’t you go outside and play Scoots, it’s such a nice summer day. Every day you spent here over the winter you wanted to be able to go out as I recall.” She says.

Scootaloo turns around and looks at Rarity but without moving her hoof from her crotch.

“Yes, go out and get some exercise, it’ll be good for you.” Rarity continues.

“Okay… I’ll go,” replied Scootaloo as she stood up, knowing that once her babysitter has made up her mind on this sort of thing she won’t be persuaded otherwise. She proceedes toward the back door at the rear of the kitchen but is stopped halfway by Rarity who kisses her forehead and hugs her tightly.

“Love you.” Is all Rarity says giving Scootaloo a quick rub on her butt.

Though being forced from her comic, Scootaloo’s mood is good enough that she trotted to the door on her way out to the backyard and continued trotting over to the swing set. She decided on the middle of the three swings, a place she usually doesn’t get when Sweetie Belle is home, and begins swinging gently, feeling more relaxed and content than hyperactive. Lost in her gentle motions she watches birds fly about overhead and listenes to the leaves rustling in the trees.

Despite these distractions, after a while her need to go to the bathroom and pee becomes too strong to simply ignore any longer. She stops her swinging and looks down at her crotch wondering what to do.

“Jeez, I have to go pee, but I just got out here. And I’d like to keep on swinging… so I’ll just try to hold it some more,” Scootaloo says to herself.

Though after a bit more swinging, Scootaloo took notice of her model carts and wagons in their sandbox and decided to play with thoes instead, having quickly lost interest in the swing set as something new caught her attention in the way of most foals. She hoped off the swing and walked over to them, feeling her full bladder the whole way. Getting down on her butt she moldes the damp sand of the sandbox in front of her into miniaturized, if rather imperfect, replicas of various roads and building from nearby Ponyville, or from what she could recall of her trip to Canterlot the year before. She uses this cityscape as a place for her imagination and her toy carts to run wild.

After a few minutes, her body again tells her it wants, no- needs,
to pee.

So she again lookes down at her crotch and thinks to herself; “Why do I always have to stop playing just to go inside to pee. What would happen if I just keep playing and didn’t go back inside? I bet I’d wet my pants? Would that really be so bad? Would I get in trouble?”

Scootaloo’s not to sure of the answers to her questions without actually trying anything and turns back to her sand and model cart city, not ready for any commitments.

A few more minutes pass, and Scootaloo’s body continues signaling her it is time to pee with ever increasing force. She obstinately ignores the message and continues playing. Even more minutes pass, and this time her body, now quite fed up with an overfull bladder, starts releasing urine. Of course, it had no place to go but into Scootaloo’s overalls. She feels the wet warmth as her pee as it began to moisten her crotch. She sat up and looked down at her crotch, watching it get wetter and warmer.

Scootaloo’s rather surprised with herself, she’s doing it alright; she’s wetting her pants!

Her peeing rate increases as whatever pressure she had left to hold it in is relaxed. The front of her light blue overalls is shining with wet pee as Scootaloo continued to watch herself wet them. The overalls, quickly soaked with urine, began dripping onto the grass and down her back legs. Scootaloo just stays there on her butt, and watches herself as she wet her pants.

She likes it.

She liked that she is still playing outside and didn’t bother to stop and use the bathroom at all. As her bladder emptied itself, the flowing pee finally stopped and she sighs.

“Good, no more having to go to the bathroom! I can just stay outside.” So she did just that and kept right on playing.

After a good half hour of building roads, bridges, houses, and even attempting a castle on a mountainside for her toys to interact with, she realized that she is becoming somewhat thirsty. She finally got up, now having a better reason to return to the house.

“Hey Rarity, I’m thirsty. Can I have some water, please?” asks Scootaloo as she came walking back into the kitchen.

She sees Rarity at the kitchen table, reading something, another magazine probably. Rarity looked up at Scootaloo and immediately notices the color of her shorts. The crotch area, all the way to the hem, is much darker than the denim on the sides. She knows what happened and decides Scootaloo should at least explain herself. Rarity decided also that she will do what she can to get Scootaloo to wet herself even more.

“Okay Scoots, you can get some water. Pour a glass from one of the jugs in the cellar, I just filtered some more from the rain barrel. Then come on back over here.” Replied Rarity.

The filly in her wet overalls walks down the creaky old steps to the cool cellar under the house with clean glass held in a curled wing and pours a glass of water, careful not to break the heavy ceramic jug in the process. Returning up the steps, she walks to Rarity’s side sipping at it all the while.

Rarity waits patiently as she finishes off half of the glass and eventually sets it down on the table.

“Goodness, you sure are thirsty alright. You must have actually played pretty hard to get that way in under an hour.”

“I sure did! It was really fun, now I just want to go back and play some more.” Says Scootaloo.

‘I was right; it was a good thing for her to get out on a day like this.’ Rarity thinks to herself.

“Well, before you go back, please explain yourself,” says Rarity.

“What do you mean? I was playing a lot and got thirsty,” replies Scootaloo.

“And you were having so much fun that you forgot to come in and use the bathroom?” Asks Rarity, the corners of her mouth threatening to twitch up in a smile.

Scootaloo suddenly realizes what Rarity is talking about. She looks down at her overalls and sees the large wet area covering their front, clear evidence that she wet them.

“Oh, this…” she says still looking at her wet pants. She looks up at Rarity with a fillyish grin and a smile.

“Yes, Scootaloo, those,” says Rarity pointing a hoof at her wet shorts.

“So, what happened?”

“I told you, I was playing a lot,” said Scootaloo.

“And what happened then?” askes Rarity.

She was now definitely smiling to herself, at least on the inside, thinking about this filly she is looking after this week and how wrapped up in her own world she could get. Though since Scootaloo hadn’t played this much and ended up with wet pants before Rarity couldn’t help become curious to find out what was so different about this time to result in the peed in overalls.

“Oh, well, I was just having such a good time playing that I didn’t want to stop and come it to use the bathroom,” Scootaloo said in reply.

“So you knew that you had to go then?” asked Rarity.

“Yeah,” replied Scootaloo with a slight blush and a sheepish look at the floor.

“Well then, what happened?”

Scootaloo looked back up to Rarity.

“Well, I just kept holding it in and it finally started to come out. I felt it coming out and then looked down and saw that I was going pee. So, I guess I was wetting my pants and when I was all done, I went back to playing until I got thirsty.”

“I see, so you wanted to keep playing, knowing that you had to go to the bathroom and decided to wet your pants instead, is that about right?” asked Rarity.

Still looking at Rarity, Scootaloo replied, “Yeah, that’s about it, I decided to wet my pants instead of having to stop playing.”

“And you are okay with that?” asked Rarity.

“Yes Rarity, I’m fine. I didn’t mind it at all,” said Scootaloo.

“Even if fillies your age usually go to the bathroom and not in their pants when they feel the need to go?” Rarity asked.

“Well, I suppose so; I just didn’t want to stop and come in. I knew what I was doing and that I might get in trouble for going in my pants, but… I just wanted to, I guess,” replied Scootaloo, looking like she expected to be reprimanded.

“I see. Well, you’re not in any trouble, I just want to understand why you decided to wet your pants. Do you think you might do so again? asked Rarity.

“Well, not if I get into trouble, that’s for sure,” replied Scootaloo.

“So if you do get into trouble then maybe you won’t, is that right?” she asked.

“Oh, I don’t know Rarity. I definitely don’t want to get into trouble, but I might not want to stop playing and I might end up wetting my pants again.” Said Scootaloo.

“I see; well, you’ll not be in trouble if you end up wetting your pants again. I want you to know that. I also want you to know that I’ll take care of you no matter what happens, wet pants and all. We’ll just see how things go from here on, okay?” said Rarity.

“Thanks Rarity, I love you!” Scootaloo smiles and hugs Rarity before going back outside to continue playing, having never bothered to take off her still quite damp overalls.

Rarity watches Scootaloo go back outside and smiles to herself. She’s sure that within the next week, if not sooner, she’ll wet her pants again. She’s not quite sure she understands why, just that Scootaloo was so sure of herself when discussing her actions that she’ll do it again. She’s apparently not even bothered by wearing her pee-wet clothes. Rarity begins to think of how she’ll respond and what she’ll do when it does happen again.

Scootaloo plays some more that afternoon without another pants-wetting incident. She comes into the house after a few hours to use the bathroom and change out of her overalls. Rarity smiles at her each time she comes in and she simply smiles back. It’s as if they both know what the other is thinking, and are just waiting for the next move in this chess game of sorts.

The same scenario plays out over the next three days. Causing Rarity to rethink her previous conclusion that Scootaloo would wet herself again within a week. Maybe it was just a one-time occurrence? Meanwhile, just in case, she acquires a few items from her boutique that might perhaps become useful to Scootaloo if she decides to continue to wet herself more.

Only time will tell.

Scootaloo thinks about what she did when she stayed outside to play and ended up wetting her overalls every time she goes to the bathroom. As she watches her urine stream flow into the toilet, she remembers how she felt when it was going into her pants. Each time she urinates she thinks about wetting herself again, but is not sure how Rarity will react.

Rarity said she wouldn’t be in trouble if she did wet herself again, but Scootaloo’s doubts linger.

She admits to herself that she really did like doing it, even though she knew she shouldn’t. The excitement of doing it anyway itself is what excited her she finally realizes.

After eating a good breakfast, Scootaloo goes to read another comic book she’s been looking forward too. Today Rarity’s dressed her in only a pair of faded denim short shorts, a size too small, but oddly more enjoyable to wear because of that.

Lying on a cushion and again with a hoof to her crotch, Scootaloo got back to reading. Rarity kept an eye on Scootaloo throughout the process. She’s done this same routine over the past few days, but today, she seems somehow different, quieter and withdrawn but subtly so. She hopes that Scootaloo is alright and wonders what is on her mind. Is she thinking of doing it again? Rarity wonders to herself.

After an hour of reading and several more comic books, Scootaloo gets up and goes into the kitchen where she finds Rarity. She walks up to her and gives her a hug.

“Thank you honey,” Rarity says.

“Are you okay, you seem quiet this morning?”

“Yeah, I’m okay Rarity, just thinking. I’m going outside to play. I’ll be back in a while.” Responds Scootaloo.

“Well okay then, you have a good time outside.”

Scootaloo hugs Rarity again and runs back out to the yard. Rarity watches for a minute before going to find her earlier purchases for Scootaloo, just to be prepared. She’s sure that Scootaloo will be wetting her pants today and she’ll be ready for her when she returns.

Outside, Scootaloo goes swinging again, a favorite activity for her. As she builds momentum her bladder signals her that it’s getting full. She’ll need to pee soon but she smiles and keeps on swinging.

“I wonder if I can pee while swinging,” Scootaloo wonders to herself.

It is as if she’s already decided she’s going to wet this morning, the only task left is to just figure out where.

“I’m going to do it.”

“I’m going to wet my pants…” Scootaloo says to the otherwise empty yard.

As she swings she looks at her crotch, relaxes herself, and waits. She feels nothing coming out, and so decides just to keep swinging and see what happens.

After a few minutes the urge from her bladder signaling its need to empty itself returns. She decided not to fight it and tried her best to stay relaxed even though she began to feel excited by the prospect of wetting her jeans. She kept swinging and tried pushing her urine out a bit. Finally, her body began to respond and as she watched her crotch, a wet mark began to appear. Scootaloo’s excitement increased as she began to feel her urine travel down her penis and into her tight jeans shorts.

‘The feeling really is nice’; she thinks to herself.

She pushes more and the mark grows larger. She watches as urine enters her shorts and spreads out, darkening the otherwise light blue fabric.

She slows down her swinging and finally comes to a stop, watching the wet mark grow larger as she continues to pee into her shorts.

“Yes, I’m doing it, I’m wetting my pants!” She says out loud.

Scootaloo’s bladder is now in full discharge and her shorts tell the story. Her urine is covering the front of her shorts, flowing underneath her to soak into her butt, and begins to stream down her legs, eventually dripping down onto the lawn as the flow continues. She feels excited and happy with what she’s doing in her shorts.

As her bladder empties, Scootaloo starts up swinging again; this time with even greater intensity. Excitement flowing through her body, she’s very happy with herself and her wet pants.

Rarity has been watching Scootaloo this entire time and smiles. She can tell Scootaloo is happy with herself and her wetting. She knows what to do when Scootaloo comes back inside, though she still doesn’t understand quite why Scootaloo has done this again but she knows that Scootaloo is happy with herself and that is more important.

Scootaloo stops swinging and goes over to the patio and begins playing with her wagon and the large wooden blocks her dad cut and sanded for her that she had brought over for her stay in Rarity’s house. She keeps looking down at her wet jeans; she’s intrigued by them and how they feel. After about an hour more outside Scootaloo gets tired and decides to come back into the house. She smiles at Rarity as their eyes meet in the kitchen.

“Hi Rarity,” says Scootaloo.

“Hi there yourself, having a good time outside?” Rarity asks.

“Yes, a great time. I’m tired though,” replies Scootaloo as she walks to the pantry for something to eat.

“Well good for you,” replies Rarity as she reaches out a leg to Scootaloo.

Scootaloo walks to her and she gives Scootaloo a hug. She then kisses her forehead.

“Feeling better now?” asks Rarity as Scootaloo munches on a kiwi fruit.

Scootaloo looks into her eyes and smiles.

“Yes Rarity, I feel much better!”.

“And why is that?” asks Rarity, with an eyebrow raised.

Scootaloo looks at her sheepishly, knowing what that expression is referring to.

“Because I wet my pants.”

“Well, if that’s how you feel, and you are so okay with wetting your pants, then I think it’s okay to let you wear something more appropriate to your desires. In this case that means diapers I think.”

“Come with me to the bathroom,” says Rarity as she stands up and presses a hoof to Scootaloo’s behind, leading her towards the back of the house.

Scootaloo says nothing and follows Rarity, she’s not sure of what to feel now. ‘Diapers? Where had that idea come from?’ She wonders.

In the bathroom, Rarity has Scootaloo remove her tight shorts, which have by now partially dried out. Rarity can’t help glancing down to see how the still wet, thin fabric of Scootaloo’s tight panties molds itself over her penis, which seems to grow more erect as its exposed to the cool air, and the hairless, smooth pussy below it. Rarity smiles at how cute both organs are. After Scootaloo removes her panties as well Rarity has her place everything on the edge of the bath tub.

“I’ll get those wet clothes cleaned after I take care of you first,” she says.

She gets a washcloth and gets it wet with warm water, and proceeds to wipe Scootaloo’s crotch and butt, getting them all clean from her urine.

“Now let’s get you dressed so you can go back out and continue playing, I want you to be outdoors as much as possible on days as nice as this one. Only this time without having to wet your pants. You can pee in your diaper and still keep playing. Only you and I will know that you have a diaper on because only you and I know that you like to wet your pants. Does that sound okay Scootaloo?” asks Rarity.

Scootaloo looks up at Rarity with a young filly’s smile.

“Yeah that sounds good.”

At her Rarity’s instruction, she races out of the bathroom and into her bedroom, where she jumps onto her bed; showing off her cute butt to Rarity as she leaves the bathroom.

Rarity smiled to herself.

“Well, diapers it is for that filly. She’s obviously not bothered at all by the prospect of wearing them. If she’s okay with them, then so am I.”

She finds Scootaloo on her bed, hooves touching herself, and in a very good mood. She goes to her closet and takes out the diapers she recently purchased for this occasion. Walking back over to Scootaloo. She looks down at her seeing that she’s again anxious to get back outside, and to probably play with herself.

“Okay my little filly, any filly that has that much fun playing and ends up wetting her pants needs a diaper, and that's what I plan to give you. Now lift that cute bottom of yours so I can diaper you,” says Rarity.

Scootaloo eagerly complies and Rarity quickly places the diaper beneath her butt.

I’ll have you diapered and back outside in no time,” says Rarity.

After sprinkling a little powder on her crotch and rubbing it in, she brings up the thick disposable diaper between Scootaloo’s legs where she snuggly fits it on Scootaloo and tightly fastens the tabs. She then shakes open a pair of clear pink plastic panties and places Scootaloo’s back legs through them and pulls the plastic panties up to her diaper. Scootaloo lifts her butt up so Rarity can bring the panties up over the diaper. Rarity then goes over to her dresser and gets a pair of denim overalls, and returns to put them on Scootaloo. Scootaloo stands up and Rarity adjusts the plastic panties to completely cover the diaper. She then has Scootaloo step into her overalls as she brings them up to her waist and pulls the straps over Scootaloo’s bare shoulders.

“There you go, my little filly, all freshly diapered,” says Rarity.

“Thanks Rarity, you’re the coolest. You didn’t even get mad at me or spank me ‘cause I wet my pants, you just put me in a diaper.” Scootaloo says looking up and smiling.

Rarity leans down and kisses Scootaloo on top of her head

“You’re welcome Scoots, I told you that you would not be in trouble if you wet yourself again. I think that diapers are what you need right now so that is why I got you some. You may use them as your toilet as this seems to be what you want. I’ll change you if you really need it. Now go out and play away,” she says as she gently swats Scootaloo’s diapered butt as Scootaloo races away.

A Look Back pt. 2

“Wow this is just the best,” Scootaloo says to herself.

She notices this pair of overalls are rather a bit snug over her new diaper and she can hear it crinkle softly as she walks. She goes over to her model cart and begins stacking logs in it, in preparation for yet another playtime adventure.

Rarity smiles as she watches Scootaloo. She has her wet shorts held in her magic field as she takes them and other items of clothing to the laundry room for washing.

Scootaloo is again lost in her own world while playing when she feels another urge from her body. This time her bottom feels a growing pressure and she knows what’s to come next. Scootaloo stops playing and looks down at herself and then over to the house.

“Well, Rarity told me I can use my diaper as my toilet… so here goes.” Scootaloo says quietly to herself.

She gets onto her knees and begins to push, and is quickly rewarded with lots of soft poop filling her diaper. The more she pushes, the more poop comes out. It feels wonderfully warm and squishy against her butt. She quickly finds herself liking the feeling and pushes even more, as she wants to fill her diaper as much as possible.

‘Oh wow! This feels great! I’m going poop in my diapers and I like it, I love to go poop in diapers!’ Scootaloo thinks while smiling to herself.

As she empties her bowels, her bladder opens up and she just relaxes where she is and wets herself. Her pee comes out strong and steadily. Scootaloo just stands there while pissing and messing herself in her new diapers. She really likes this feeling and rubs herself to feel the fullness of her diaper.

Her diapers feel so good between her back legs!

Now, with the diaper very full and pushing against her overalls. She sits down on her cart, feeling her poop squish around her bottom and up the front of her diaper. She rubs her butt back and forth on the wood planks and leans forward with her back legs spread, further spreading her poop around so that it’s smeared all over her pussy and base of her young penis. Scootaloo sighs with pleasure after a few minutes of this activity before going back to playing.

She’s very satisfied with herself and with how much fun and use she’s getting out of her first diaper.

Rarity keeps an eye on Scootaloo during this period and realizes after a bit of careful watching that she’s just pooped herself and seems to be quite enjoying it.

‘Well my little filly has certainly adapted to her new diapers quickly. She’s not at all bothered by messing herself and I guess she actually does want to be back in them. I can and will go along with this if she continues to feel the need. It’s a good thing I bought a fair amount of diapers for her. She’ll be wearing them all the time now,’ she thinks to herself.

Two hours have passed since Scootaloo pooped herself. She’s also peed in her diaper again, making it feel even more full. She likes the full diaper feel as it encases her crotch and butt. Several times while playing she presses a hoof to her crotch, feeling the full diaper. She thinks to herself that maybe she should go and get her dirty diaper changed, but she likes how it feels and the mess that covers her butt and between her legs. Now peeing again, she sighs as the urine flows through her penis and gushes into her diaper.

“I love doing this,” she says to herself.

As she finishes wetting, she looks across the yard back toward the house. There she sees Rarity looking at her from the back door. She opens it to call Scootaloo back inside.

“Scoots, please come here so we can talk and see if you need a diaper change.”

Scootaloo is surprised at Rarity’s openness about changing her and saying those words so loudly, slightly afraid any passing ponies might overhear. She starts walking back to the house feeling how her wet and messy diaper feels slick and squishy against her crotch. Rarity smiles to herself as Scootaloo approaches, and her full diaper becomes even more obvious with the way she walks.

As she gets to the door that Rarity holds open, Scootaloo walks on into the house.

Once in the kitchen, Rarity asks; “Well then, how is your day going so far? Are you having fun?” She smiles as she smells Scootaloo’s poopy diaper.

“Yah, everything is just great. I’m having fun today too.”

“I’m glad, that’s good to hear. I can tell that you’ve made a mess in your diaper. It smells. How are you feeling about that?” asks Rarity.

Scootaloo looks up at her and smiles.

“I’m fine with it Rarity, I just felt the need to go and you said that I can use my diaper as my toilet… so I did!”

“And wearing your messy diaper for all this time was okay?” Rarity replies.

“Yes Rarity, I didn’t mind it at all, it… kind of felt good to me too,” Scootaloo says as she blushes.

“You’re such a funny filly Scoots, come on, let’s see if that diaper is messy enough to require a change.” She says.

Rarity takes the lead to the bathroom with Scootaloo following just behind. Once there, Rarity has her remove her overalls so that the diaper and plastic panties are again the only thing Scootaloo has on, before having her lie down on her bed.

“I’ll need to get you a changing pad for your changes one of these days, so you
won’t get the bed or other furniture dirty, but for now, we’ll just use a towel. Now lay down here so Rarity can see her diapered filly.”

Scootaloo gets on the bed as asked and looks up at Rarity as she prepares to open her diaper. Rarity places her hoof on the front of Scootaloo’s thick diaper and slides it down to her crotch in an effort to feel its fullness.

“Goodness me; this little filly has truly filled her diaper this morning. It’s wet and messy and very full,” says Rarity as she continues to rub her crotch through the thick diaper and smooth plastic panties.

She removes the panties, pulling them down Scootaloo’s legs and then pulls the diaper’s tabs gently before pulling back the diaper between her spread legs exposing her very messy crotch, now covered with poop made even more slimy by her pee. The smell of her mess hits them both.

“Well, Scootaloo you’ve filled this one very well so far,” says Rarity as she smiles down at the filly.

Scootaloo returns the smile with her own, saying; “Yeah Rarity, I did, I filled my diaper good!” She then can’t help but giggle with amusement at her own statement.

“Yes you did, Scootaloo, and it’s okay with me, too. You’re a diaper filly, one that must wear diapers because you like your pee and poop filling your pants,” replies Rarity.

She notices that Scootaloo is a bit aroused as Scootaloo’s poop smeared penis is erect. “And it looks to me that you really are enjoying all of this, my little diaper filly.” Rarity says.

Scootaloo blushes again and just nods her head yes.

Rarity decides it’s time to give Scootaloo a bit of sex education during this opportunity, since she sees Scootaloo is erect. She explains to her that when her penis is hard as it is now, that means she must be aroused and excited. She says that getting hard is a very normal thing for colts and also for fillies who have a penis as well, and that she is not at all mad at her. She explains to Scootaloo that her wearing and using diapers excites her and that she is okay with this and so should Scootaloo.

“Also having your wet and messy diapers being touched by somepony else like I was just doing when you wear them will also help you become aroused.” Rarity ads.

“I just want you to know this Scootaloo; it is okay for you to be excited with diapers. Fillies get excited over different things, and diapers are one of thoes things. Don’t feel guilty or weird because of this Scootaloo, you are a wonderful pony, and even better as one that likes diapers,” says Rarity with a reassuring sound in her voice.

“Thanks for telling me Rarity, I do like diapers, and I love using them,” replies Scootaloo.

Rarity leans down and kisses Scootaloo again but this time on her mouth instead of her forehead.

Seeing that Scootaloo likes wearing her used diapers so much, and that the diaper has not yet leaked very much, Rarity decides that Scootaloo should be able to enjoy wearing them for a while longer before needing a change.

Scootaloo grins up at Rarity as Rarity pulls the thick disposable diaper, its inside smeared with poop and heavy and pee, back up between her legs and over her crotch covering her thin light pink pussy and smooth penis, and once again taping it tightly in place.

Rarity can’t help but spend a minute rubbing Scootaloo’s erection through the bulky diaper as the smell of poop continues to fill the room.

“Now, stand up so I can get your plastic pants to cover all of your diaper. We don’t want any leaks escaping into your pants, do we?” asks Rarity.

“No Rarity, no leaks from my diaper,” says Scootaloo as she complies with her request.

Rarity gets the plastic pants to cover all Scootaloo’s diaper again and then lifts her off the bed and onto the floor, a task that is not nearly as easy as the last time she looked inside Scootaloo’s diaper. She then hugs her and gently rubs her messy diapered butt.

“Now get your overalls back on and get back to playing. Stay close to the house so I can find you when it’s time for me to check on the state of your diapers again.”

“Okay Rarity,” replies Scootaloo as she puts on her denim overalls back over her heavily used diaper. She looks down at her diaper and then up to Rarity.

“Thanks for looking inside my diaper Rarity, I like when you check it!”

“I like checking your diapers too Scootaloo, even though you are nine years old and
using them again. It’s okay with me because you are okay with wearing and using them,” she says.

“Yep, I sure am!” Says Scootaloo as she scampers from her room, her un-changed diaper and its contents squishing pleasurably between her legs as she runs.

Rarity smiles as she watches the diapered filly leave the room.

“Yes.” She says to herself, “That filly will be in diapers for a while. I wonder if Sweetie Belle would like to wear diapers with Scootaloo when she returns from that summer camp.

A Look Back pt. 3

With Scootaloo wearing and using her diapers more over the past few days, Rarity realizes that Scootaloo is going to need some new clothes; clothes that are big enough to cover her bulging diapered butt.

So, after having breakfast, Rarity says, “Well, Scootaloo, we’re going out now to get you some new clothes. After that, we need some more diapers since you are now wearing them all the time. How does that sound?”

“That’s cool Rarity. I’d like that, most of my shorts and jeans are too tight over my diapers.”

“I see. Scootaloo, are you are still okay with wearing and using a diaper as your toilet?”

“Yes Rarity, I like being in diapers; there’re cool and they make me feel good, too.”

“Okay, diapers for you, so let’s get you some new clothes.” Says Rarity.

Rarity grabs her purse, Scootaloo’s diaper bag, and they go out through the front door and head on down the cobble paved road into Ponyville.

When they arrive, they find a small filly’s clothing store that Rarity usually never goes to as she likes to make Sweetie Belle’s clothes herself if she can. There, Rarity finds potential shorts and skirts for Scootaloo. She leads her to a changing room, and proceeds to have Scootaloo try them on to see which ones are the proper size. Scootaloo steps in and out of the new clothing with her diaper on while Rarity checks for the proper fit. They have decided on several new pairs of jeans shorts and two skirts. Rarity wants to go and see what other ones are available, now that she knows the size.

“Come with me, let’s go and see what other options are here for you, okay?”

“Sure Rarity, I like these ones a lot.” replies Scootaloo who is still wearing the last shorts she tried on. She looks down and rubs her crotch through the shorts and diaper.

They both leave the changing stall to go check out some more clothes. Going over the racks, Scootaloo and Rarity chat about various colors and prints of the items they come across. They agree on two more pairs to try on and begin to return to the changing stall.

“Hi there Scootaloo!” Comes a call from nearby.

The two look around to see the source of the voice and see Twist, a friend of Scootaloo from school, and Rarity sees her mom, Cookie.

“Hey there Twist!” Scootaloo replies first, followed by Rarity, “Nice to see you Cookie, and Twist. Seems you’re in need on new clothes as well?”

“Yes we are.” replies Cookie. “Twist here is growing so fast out of the few clothes she owns.”

“Same for Scootaloo.” says Rarity as she looks over and smiles at Scootaloo.

Scootaloo returns her smile with her own and a bit of a blush. The two older ponies chat a bit about what Sweetie Belle is up to and how Scootaloo is doing while Scootaloo and Twist exchange their own news of their lives. After a bit, Rarity tells Cookie good-bye and leads Scootaloo back to their stall.

“That was nice getting to see and chat with Cookie and Twist, don’t you agree?”

“It was nice Rarity. We had a good chat.” replies Scootaloo.

“Well that’s good, I want you comfortable and confident when you’re out and running into your friends. You see, your diapers have no effect on how you behave or how others respond to you. I’m glad that you’re okay with wearing them all the time, and your new shorts cover them well so it’s not so obvious you are wearing a diaper either.”

“I’m fine with wearing them on errands, I thought about them for a second when we were talking with Twist and Cookie, but quickly forgot about them.”

“That’s good to hear. I’m happy that you are so comfortable with them. What will you tell Twist or Sweetie Belle if they find out that you wear diapers?” Rarity asks as she opens the stall door and brings Scootaloo in.

Scootaloo stands there with a questioning look on her face that slowly turns to confidence, as if Scootaloo had just gone through in her mind the series of events and her response.

“Oh, I’d tell her that I have wet myself a few times lately and that you feel I should wear diapers until the wettings stop. I’d say that it’s okay with me because I’d rather wear a diaper than wet pants at school. After all, accidents happen and diapers are just a different
kind of underwear, that’s all.” replies Scootaloo.

“Well good for you Scoots. I’m glad you thought about this and I don’t mind taking the credit for putting you back into diapers, even though we both know you like wearing them and like wetting your pants too. Now, let’s see how these other clothes fit you.”

Scootaloo tries on the other new shorts and tells Rarity which ones she likes best. After this activity Scootaloo is left in just her diaper.

Scootaloo looks down at her diaper as she sits on the bench in the changing room.

“Hey Rarity, look here.” As she speaks, Rarity looks down at Scootaloo and then to her diaper where she sees the thick disposable diaper begin to change colors from white to light yellow. She watches as Scootaloo stares down at her diaper and brings her hoof up to Scootaloo’s crotch and holds her there, feeling the warmth of her pee and the force of it as she wets her diaper.

“You go filly!” she says.

“I can tell that you really enjoy being in a diaper. You just love using them.”

“Oh yes, they are just the best.” replies Scootaloo as the two make eye contact. “I’m wetting myself and I like it, Rarity.”

“Yes, I know you do, and it is okay with me that you do. Just let go and get all your pee out into your diaper. I think you should wear a pair of new shorts from here on, now that your diaper is a bit larger with all the pee in it.”

As Scootaloo’s urine flow finally tapers off, Rarity removes her hoof from Scootaloo’s crotch, but not before continuing to rub it several more times.

“You did well to wet yourself right here in the stall and not be embarrassed. Which pair of shorts would you like to wear?”

Scootaloo smiles at Rarity and sighs with relief from her wetting and chooses a pair of jeans shorts. Rarity smiles at her and helps her get the shorts on.

Their shopping done and everything in bags, Rarity asks; “Well, are you hungry? Because I am. We spent a long time shopping for you today. What do you say?”

“Oh yeah Rarity, that sounds good to me too.”

“By the way, how is your diaper? Are you in need of a change before lunch?”

“I don’t think so, I only wet it some more.” says Scootaloo as Rarity feels her diapered butt and crotch to see for herself the extent of its wetness.

“You’re right, I don’t think you need a change yet, we can deal with that after lunch.”

“Thanks Rarity, I like wearing a wet diaper.” Says Scootaloo, smiling while rubbing her diaper through her shorts.

“I like you in wet diapers too, Scootaloo. I know that you like wetting your diaper, and that first pee you did in the stall was a big one. I figured you’d wet yourself again before lunch as well, but that the diaper could hold it.”

Scootaloo blushes, “Yeah Rarity, it feels good and I get excited knowing that I am wetting my diapers. I like them and I like you feeling them too.”

“Well, I like that you like wearing and using diapers too and I enjoy feeling them as you do so.” Rarity says trying not to laugh.

“Even if I do a big stinky poop in them too?” asks Scootaloo.

“Yes Scootaloo, even when you do a big smelly poop in them too. I love you and want you happy, you just keep wetting and messing your diaper and I‘ll keep changing them whenever they get too full to keep the mess inside, deal?”

“Deal, Rarity.” replies Scootaloo as a big smile appears on her face. Rarity smiles back at her and then pulls up Scootaloo’s plastic panties and shorts. After checking on Scootaloo’s wet diaper again they leave the clothing shop and head for a nearby restaurant for some lunch, side by side.

After their mid-day meal, they head to Rarity’s own store, the Carousel Boutique, which while generally specializing in adult mare’s clothing, also stocks an assortment of diapers for all ages except for infants. Incidentally, the same place Rarity got Scootaloo’s first set of diapers two weeks ago.

“Hey Rarity, these diapers are cool looking.” Scootaloo says, holding a package of 24 thick disposable diapers with a light pink plastic surface.

“Well, let’s see if they’ll fit you then.”

She sees that the package Scootaloo chose is the proper size for her.

“You’re in luck, these diapers will fit you just fine. We’ll need another package or two since you use them so much.” She says as she looks to Scootaloo. Scootaloo returns the smile, but then Scootaloo’s expression changes to one of concern. Her body is saying that it’s time to poop right now. She grunts a bit and then looks to Rarity, who knows immediately that Scootaloo needs to use the bathroom from her experience with Sweetie Belle.

“It’s okay, you just do what your body wants, don’t worry about anything, you just let go and use your diaper. You know that you want too and I am okay with that. Just do it Scootaloo, pee and poop your diaper right now.” Rarity says with encouragement in her voice and her
hoof on Scootaloo’s shoulder.

Scootaloo looks up at Rarity and then begins to open her bowels. She keeps looking at Rarity as her poop begins filling the back of her diaper and she pushes and pushes her poop. Her body responds and begins filling the diaper, and the smell is noticed by them both.

“That’s great Scootaloo, don’t worry, just do it in your diaper. Get all that poop out now, you can do this, I know you can.”

Scootaloo continues pushing her poop, she’s not holding back anything. As her diaper fills up, her bladder opens and she beings to wet her diaper too. Scootaloo’s expression changes to one of satisfaction and contentment. She’s doing it, she’s pooping and peeing her diaper with Rarity, in public, in her own store. “That’s my good diaper filly.” Rarity says as she notices Scootaloo’s expression. She’s happy for her that she’s using her diapers just the way she wants.

As Scootaloo finishes emptying her bladder, Rarity places her hoof on Scootaloo’s butt and feels the massive bulge there. She them does the same for her crotch area and feels the warmth of her urine and her erection inside the diaper.

“You did a good job, you filled your diaper and it didn’t leak, you can’t even tell that you’re wearing a wet and messy diaper with your new shorts. Though, if Rarity is honest with herself this is a bit of a white lie.

"How do you feel?”

“Oh, wow Rarity, it was so good to just let go and use my diaper for everything. I didn’t have to run to the bathroom or hold it, I just did it in my diaper. It feels good Rarity; it feels really good.” Scootaloo says with relief.

“That’s great to hear, it’s so nice that you like using your diaper anywhere you are. I’m glad that you like them and like pooping and peeing in them too; after all, you are my diaper filly.”

They finish selecting some more diapers and Rarity also gets some powder and wipes for the occasional diaper change.

This time, instead of walking back home, Rarity hails a taxi carriage for them and their bags of clothing and diapers.

As they get into the cab, Scootaloo enjoys the feeling of sitting down on the hard wood slats of the carriage’s bench, making her poop squish up the front of her diapers, especially when she leans forward to adjust the bags at her feet. The warm, slimy poop just feels so good as it works its way up and over her pussy and penis inside of her thick diapers.

“Well I must say that you did a good job stinking up the store.” Rarity comments.

“And that’s ok, diaper fillies do that sort of thing; they can’t help it; they just need to use their diaper.” She laughs a bit as she looks at Scootaloo.

“Thanks Rarity, it felt so good to let go in there and poop myself. I really liked doing it. As for the smell, oh well, it doesn’t smell that bad.” says Scootaloo followed by her own little laugh.

Once home, they both unload the purchases. Scootaloo helps Rarity bring the stuff to Rarity’s bedroom where they put things away. Neither of them minds the smell from Scootaloo’s diaper or the fact that she’s still in it. She’s in no hurry for a change, and Rarity can sense this. She checks Scootaloo out as she walks and smiles to herself that her new shorts do a very good job of concealing her diaper and all that she’s done in it.

She leaves Scootaloo in her room so she can put her own things away. Scootaloo is content with herself and her wet and messy diapers and begins playing with the toys in her bedroom.

An hour or so later Rarity calls up from the kitchen, “Scootaloo, Cookie just dropped by and said Twist wants to know if you want to come over and play in a while. Scootaloo comes down the stairs with a smile on her face.

“Yes please, she’s a neat filly and I always like playing with her! But um, before I go though, would you please change my diaper?”

A Look Back pt. 4

Rarity leads Scootaloo to her bedroom and places the new changing pad she bought on her bed.

“Come here you big filly, let’s get your diaper changed.” She says as she pats the changing pad.

Scootaloo smiles and climbs onto Rarity’s bed, lying down on the pad Rarity removes Scootaloo’s shorts and plastic panties. She looks at Scootaloo’s very wet and messy diaper and begins to gently rub the diaper’s front.

“Well, you sure do need a diaper change. Had you wet once more, you would have leaked all over into your new shorts for sure, even with the plastic panties. Rarity can see the brownish fluid that had already seeped into Scootaloo’s plastic panties from the over full diaper and knows that another heavy wetting would have been too much even for them.

Scootaloo again smiles.

“I just can’t stop using my diaper Rarity. It feels so good to just let go in it and feel how warm and squishy it gets. I knew I needed a change and that’s why I asked you for one, before I go to Twist’s house.”

“Well, I’m glad that you are aware of how much you use your diaper. As long as you’re staying at my house I’ll be here for you to change you, whenever you have the need. Now let’s get this super stinky one off you, okay?”

“Okay Rarity,” replies Scootaloo.

She proceeds to open Scootaloo’s diaper exposing its contents and Scootaloo’s
erection to her.

“Here Scootaloo, let me show you a new way to enjoy your diapers. It might help you work out some of your extra energy.”

“Um, ok Rarity. What’s that?” She asks.

Gently pushing on Scootaloo’s poop smeared erect penis with the tip of her hoof, Rarity begins to rub it up and down its length, slowly at first, but then with increasing intensity. The warm slimy poop helps to lubricate her hoof and adds to the pleasure Scootaloo begins to feel.

“Wow Rarity, this feels so good! It felt nice before, when it was in my diaper, but this feels even better.”

“I know it does Scoots, I want to show you how to enjoy your poopy diapers as much as you can, and this is one of the best ways there is. Honestly I probably should have shown you how to do this earlier, even before you began to wear diapers.”

Scootaloo begins to breath heavily and close her eyes, and in under a minute she groans and her body shudders and a bit of clear fluid leaks out of her penis and mixes with the poop now covering Rarity’s hoof.

“Oh wow Rarity, that was so cool!” I’ve never felt so good; I’m going to do that every time I use my diapers from now on!

Rarity laughs as she uses a baby wipe on her hoof.

“Oh, I’m sure you will. And I’m sure that you’ll become very good at learning how to make yourself feel good. Perhaps next time I’ll show you how to make yourself feel even better by touching your pussy too.”

“You mean this here?” Scootaloo askes pressing a hoof to the poop smeared pink folds right below her penis.

“Yes, that there. But that can be dealt with later, right now, it’s time to get you into a clean diaper.

After sprinkling her crotch area with baby powder as the last step in the cleaning process Rarity brings up the front of the diaper between Scootaloo’s legs. She then securely fastens the tabs in place. Since Scootaloo had worn the same plastic panties since last night, Rarity goes to her dresser and gets out a fresh pair.

“Here you go my cute big filly, a fresh pair of plastic panties for your diaper. This will help keep you from leaking while at Twist’s house.”

She then pulls the plastic panties, green ones this time, up onto Scootaloo’s diaper as Scootaloo raises her butt so that Rarity can perform the task. She then puts Scootaloo’s new shorts on her and asks her to get up and onto the floor. She then adjusts the shorts to cover her diaper and gently pats Scootaloo’s butt.

“There now, diaper filly, what will you do at Twist’s when you’ve wet yourself? Will you be careful not to pee too much and have your diaper leak? You wouldn’t want to leave a wet mark on her furniture, would you?”

“No Rarity, I won’t do that at all. I’ll be careful and come home for a change before it gets too wet.”

“Okay then, you’re all set to go play.” Scootaloo hugs Rarity and thanks her for the unexpectedly nice diaper change. She then runs out of Rarity’s room to go to Twist’s house.

Upon arriving, Scootaloo knocks on the door. Within a few seconds she hears a pony approaching and the door opens.

“Hi Scootaloo, come on in.”

She walks in and sees Cookie, Twist’s mom. She says hello to her as the two fillies race off to Twist’s room. When they get there, Twist shows Scootaloo her new toys and new school supplies for the upcoming year and the two of them settle down on the floor next to Twist’s bed and chat about random things while absently playing with various toys.

Scootaloo wound up being distracted enough by being in her friend’s room that she didn't consider the fact that at times she leaned far forward enough that the top of her disposable diaper would show.

It appeared to Twist that her friend was wearing some very different panties, or something. Twist could also see up Scootaloo’s shorts a bit and saw what she thought was plastic-looking material. She also noted that her friend’s shorts looked stuffed and puffy on her.

‘Is she wearing...a diaper?’ Twist thinks to herself.

‘Why would she be wearing that during the day? Does she get put in diapers at night like I do? I wonder if she would tell me if she did?”

Scootaloo finally notices Twist’s attention on her and not what they are talking about. She becomes a bit self-conscious at first and blushes a little before she brings herself back under control.

Twist doesn’t see any of this and Scootaloo thinks about how she can bring up the subject of his diapers.

“I um, sort of noticed that I can see inside your shorts, I wasn’t looking on purpose, it’s just that sometimes when you moved around, I could see up inside them… It looks like you’re wearing um, a diaper, or something” Twist says hesitantly.

“Well, you’re right, I am wearing a diaper, and plastic panties on over that.” Scootaloo says.

“Wow, I never would have thought that you would be wearing one of those.” Twist holds back on saying ‘as well’ for now.

“What for?”

“I’ve just had some accidents lately… you know, wet pants accidents; so Rarity thinks that diapers will help me until I get through this and regain control.” Scootaloo tries to keep her answer simple as possible and not go into why she was wetting her pants in the first place.

“Um, do you pee in it?”

“Yes, I pee in it.”

“Wow…” Twist says, not sure what else to say. She can’t tell if her friend likes being in her diapers or not, and until she knows one way or another she is too embarrassed to discuss her own diapers with Scootaloo.

“I’m not sure I get it, but if Rarity thinks it will help…” Twist finally adds.

“Its ok, I don’t expect you to understand. I know, fillies our age don’t usually wear diapers, but that doesn’t mean that they can’t. Well, I hope you will keep this a secret between us.”

“Yah, of course.” Twist says and smiles.

She wonders if she can spend more time with Scootaloo in the future and see if her friend really does like wearing diapers like she herself does.

The two fillies play together and as expected Twist leaves to use the bathroom while Scootaloo pees in her diaper. Though Twist secretly wishes she could be wearing her own diaper during the day. Neither filly speaks about what they are doing to the other so Twist has no idea if Scootaloo needed to pee or if she has done so in her diaper. She’s too hesitant to ask that kind of question for now.

Scootaloo soon feels the need to pee again and this time she lets a little out at a time. She thinks to herself how good she feels when she urinates. She likes the feel of her pee as its works its way through her penis and then out into her diaper. Peeing, to Scootaloo, is just a wonderful feeling. The fillies play for about an hour and Scootaloo decides that she better leave soon and get her diaper changed. She’s been wetting it off and on for several hours now and can feel its fullness.

“I’ve had a great time playing, but I need to be going. I’d like to come back sometime and play more,”

“Really? I’ve had a good time too. I’d like you to come back soon,” replies Twist, happy that she might have a chance to see her friend again, and maybe ask more about her diapers.

“Thanks Twist, and you’re invited to my house anytime too, once my mom gets back in a few days.”

“Cool, I’ll be sure to ask my mom when I can come over.”

Scootaloo and Twist get up and walk out of Sweetie’s room to the front of the house. There, they meet Cookie again and Scootaloo says goodbye and thanks her for letting her come over, she thanks Scootaloo for coming over in turn and for being such a good friend of Twist. Scootaloo leaves the house and begins her walk home.

While walking home, she begins to feel the urgent need to poop. She stops walking and looks down at her diapered crotch. She contemplates what to do; should she hold it or should she use her diaper? What will it feel like to walk home in a poopy diaper? As she looks around at her diaper, her bowels again moved their contents and Scootaloo decided that why wait. She would need a diaper change eventually anyway. Rarity had said that she could use her diaper as her toilet anytime she wanted.

Convincing herself that it is okay to do so, Scootaloo relaxes her bottom and her bowels respond and she begins to poop herself. She grunts and pushes even more and poop begins to quickly fill her diaper. It feels warm and soft on her bottom and makes her diaper bulge out even more. The bulge is already large and it expands further as more poop finds its way into her diaper. Scootaloo likes what she’s doing. She likes the feel of pooping herself out in public and how her diaper is bulging with it. She begins walking again and continues pooping herself. She pushes and pushes to empty her bowels and relieve herself of the pressure on her bottom. After about a half block, she stops again and has a final push. She’s convinced that she’s pooped all she’s going to this time. She again places her hooves on both her front and backside to feel her bulging diaper. As she does this, her bladder signals that it again needs to be relieved and she gladly lets go and further pees herself. She feels the warmth of her urine flow into her already soaked diaper. She likes this feeling too. She likes that her diaper is holding everything inside and that it feels so big. She rubs her bottom and feels her poop move around against her butt and over her pussy and balls.

“Wow.” Scootaloo says to herself.

‘This is just so cool. I’ve wet and pooped my diaper right outside and it feels so good. My diaper feels great being so full, this is just the best. Maybe I am like a baby after all, I just love my diapers so much.’

Convincing herself that she’s okay with these feelings, Scootaloo begins walking the rest of the way home. Her poop finds ways to move around with her steps. Scootaloo can tell that she’s walking with her back legs spread a bit wider than usual but she just smiles to herself.

“I’ve just pooped my diapers; I am a big diaper filly and I like it.”

As she walks, she smells the first scent of her poopy diaper. She likes how she smells and feels good with what she’s done in her diapers.

Rarity is in the family room when she comes in the front door.

“Hi Scootaloo. Come here and tell me all about your day at Twist’s house,” she says.

Scootaloo walks to her and Rarity sees that Scootaloo is smiling from ear to ear.

“Well she must have had a great time judging from her expression,” Rarity says to herself. As Scootaloo hugs her, Rarity smells her poopy diaper but decides not to bring it up just yet, she wants to hear what Scootaloo has to say.

“So then, what did you say to her about your diapers?”

“She saw them when I sat down and then asked me about them. I said that I was having accidents wetting my pants and that you felt that diapers would help me through this. I said that other ponies sometimes wear diapers too. We didn't talk about them for very long.”

“Well that’s right Scootaloo, you explained yourself well. I’m glad that you are okay with Twist knowing that you wear diapers. We both know that you’re not a baby even though you smell like one right now.”

Scootaloo again smiles at Rarity, knowing that she too smelled her poopy diaper.

“I can see that they make you very happy, which is good. So, when did you poop yourself?”

“Oh it was when I was walking home. I felt the urge to go and I thought about it and that you said that my diaper is my toilet, so I did it. I just pooped my diaper.”

“Well that’s right, you did just fine. Let’s go and I’ll change you.”

“Oh Rarity, I’d like to stay in this diaper for a while. It feels really good all full and everything,” says Scootaloo.

“Well let’s see how messy you are; stand here and let me check you out.”

Scootaloo come over and Rarity unzips her shorts and drops them down to the floor. Rarity feels her diapered bottom and front making sure to squish the big soft bulge of poop in the back several times.

“Well, your diaper is not quite yet full of pee but you sure do have a large load of poop in it. How many times did you wet yourself?”

“Twice at Twist’s house, and some more after I pooped myself walking home.”

“Well, you can stay in this diaper until you wet it some more. Then I am going to change you. I don’t want you to get any nasty rash on your bottom but you seem so excited having filled your diaper that you can stay in it. Okay?”

“Thanks Rarity!”

“You be sure to tell me when you wet yourself again, and get a towel from the bathroom to sit on. I don’t want any stains on the furniture or carpet. Okay?”

“Will do Rarity, thanks again, I love you!” says Scootaloo as she scampers off to her room, via a stop in the bathroom for a towel.

Rarity smiles to herself as the diapered filly she’s been caring for this last week disappears down the hall.

“That filly certainly is happy in diapers, wet and messy ones at that.” She says while shaking her head in amusement.

A Last Look Back

With a towel spread out on the floor, Scootaloo sits down on it and proceeds to squish her poop all over her bottom. She places her hooves at her crotch and pulls her poop up, rubbing it all around her pussy and penis.

She enjoys this behavior and thinks to herself, “Maybe I am a baby… I bet they play like this with their poopy diapers too. Diapers are just so good to wear.”

Now content and satisfied with her diapers, Scootaloo continues rubbing herself and squishing her poop all around under her diaper. She likes this very much, including the smell of her poop.

Her penis has been erect since she pooped her diaper on the way home from Twist’s house and remembering what Rarity did during her last diaper change she puts special effort into putting her hooves over her stiff penis and squishing it into the poop that surrounds it inside her diapers. The warm, squishy and slimy feeling eventually makes her young body shudder.

After a short time, while she lays on her back recovering from her exertions, Scootaloo gets some toys with which to play and returns to her towel. She stays there for some time more enjoying herself, and lost in her imagination.

In the kitchen, Rarity thinks about Scootaloo and her desire to wear and use diapers. She accepts that she likes this behavior very much and further decides that she will support and encourage it as long as Scootaloo wants to behave this way. She is pleased with Scootaloo and can’t get over how confident and happy she is when wearing and using diapers.

‘I bet that filly has wet herself by now. Her diaper must be a sight. I should go check on her and see.’ She thinks to herself.

Scootaloo did in fact wet herself several more times and watched as her diaper became wetter and wetter. She also rubbed herself more, remembering what Rarity had said Scootaloo began to pay attention to the fact that her penis was not the only thing that had begun to feel good when she pooped her diaper. Scootaloo began to rub herself a bit lower down in her diaper and enjoyed squishing her poop into the area below her penis where her pussy was.

In the process, she also realized that within her plastic panties, the wetness had turned brown and was leaking onto the towel, due to her playful actions and her third and fourth pee.

She was staring at her crotch as Rarity walked into the room.

“Well, how is my diaper filly doing? Did you wet your diaper more?” she asks with a smile on her face.

“Oh yes I did Rarity, I just peed a little while ago and was playing and….” replies Scootaloo. Rarity can see Scootaloo’s diapered state and the leaks on the towel.

“That’s okay. I can see that you were playing with yourself in your diaper and it’s fine That’s why I had you use a towel. I had an idea that you would like to play in your poopy diaper. Fillies do that, you know. Let’s get you changed now and into a fresh diaper, alright?”

Scootaloo just smiles and lies down.

“Thanks Rarity. I just had the best time playing in my diaper. It felt so good and all.”

“And so you should honey. Acting this way at nine is not a bad thing. It is just different and I want you to know that it is okay with me that you like playing with yourself in your messy diapers.

“No matter how messy and smelly I get in them?” asks Scootaloo, a grin on her face.

“Especially if you get all messy; that’s what I’m here for, to take care of you on the days your parents have to go on trips. Now let’s see how good and messy you got yourself,” she says.

“Oh Rarity that is so cool. Thank you so much,” replies Scootaloo.

Rarity then goes and gets her diaper changing supplies and a fresh diaper and plastic panties. She pulls down Scootaloo’s plastic panties, exposing a very wet and messy diaper. She sees that Scootaloo has got poop all over her crotch and up the front of the diaper.

“Well, my diaper filly sure did get herself messy while playing in her diaper. I am glad you had such a good time doing so.”

“Thanks for letting me be a diaper filly. I really like it a lot and it feels so good.”

“I know it does honey and that’s why you can wear and use them all you want. She then un-tapes Scootaloo’s diaper and pulls it down.

Scootaloo’s poop smell fills the air as Rarity opens up her diaper. They both smile as they smell it.

“You are a very stinky filly, Scoots.”

Scootaloo blushes a bit at her comment.

“Yeah Rarity I sure am, aren’t I?” She giggles out loud.

Rarity does the same, “And that's fine with me, I don’t mind at all. You’re kind of cute this way.”

Scootaloo’s penis begins to grow again as its exposed to the air. Rarity smiles seeing this.

“My, my; this diapered filly does like getting her diapers changed. And so she should. Feeling good in diapers is a good thing, and we both know that you enjoy them very much. I enjoy you in them too, and changing them, Rarity says as she again holds Scootaloo’s messy erection in her hooves.

“Oh Rarity, you are just the best. Thanks,” replies Scootaloo.

“You are very welcome,” she says.

To Scootaloo’s surprise, Rarity pushes her penis forward exposing her poop smeared pussy even more and then bends down and begins to lick it. Scootaloo is amazed at how good this feels but is confused by Rarity’s behavior.

“Uh, Rarity, why are you licking me there, I’m covered in poop…” Scootaloo says while at the same time arching her back up off the changing pad slightly to press her now very sensitive pussy against Rarity’s wet tongue.

“The taste isn’t great, but that’s not the point. This is one of the best ways to make a filly’s pussy feel good, and your poop also helps. Whenever your pussy begins to feel good you can either rub it with your own hooves or ask me to lick it for you. I’ll always be happy to help you with this.”

“Wow, um, thanks Rarity!” Scootaloo says, though she is still a little unsure about this new development. She has never been licked anywhere by Rarity before. But it feels so good that she can’t think of anything wrong with what Rarity is doing.

Soon Scootaloo’s body arches further off the floor in a surge of pleasure even greater than when her penis was being rubbed. She had no idea that the parts of her body that were being covered by her poop inside her diaper could make her feel so good.

Breathing hard, as though she had just run around the house Scootaloo lays back and sighs.

“So it seems my little diaper filly enjoyed that quite a bit. I hope you will let me help you again when you get messy.” Rarity says, licking the mixture of young filly cum and poop off her lips.

And perhaps in not too long some of your friends will be interested in doing the same thing for you, like Sweetie Belle perhaps.

“Really? You think Sweetie Belle would do what you just did?” Scootaloo askes in surprise.

“She just might, time will tell though, it’s not something to rush.”

For the moment though, let’s just keep our fun between the two of us.”

Scootaloo feels so good about everything Rarity says and also with her licking and then cleaning of her messy crotch. Her penis is still fully erect with all that was going on.

Rarity finally got Scootaloo clean and went and got a fresh diaper. She brings the diaper up between Scootaloo’s legs to fastens it securely onto her cute butt. She then places a fresh pair a plastic panties on her, light blue this time. Scootaloo stands up and Rarity checks out her work to make sure the diaper is completely within the plastic panties. She then hugs Scootaloo and swats her diapered butt.

“You’re all set to go and play honey. You don’t have to wear any pants if you don’t want too. It’s okay with me if you play in just your diaper.”

“Thanks mom!” Says Scootaloo, her young filly’s body looking so cute in just a thick disposable diaper and plastic panties.

Rarity picks up the messy diaper, supplies, and towel and takes them out of her room and into her bathroom. She is very pleased with how Scootaloo’s diaper change went and the continued education she was able to provide.

She smiles to herself, thinking about the state of Scootaloo’s crotch when she removed her diaper.

‘That filly does enjoy her diapers. She had poop all over herself!’

She looks at the messy diaper being held up in her magic field, still warm from the time it spent on Scootaloo’s body.

‘Perhaps…yes, perhaps this diaper has not ended its usefulness quite yet.’ She decides as she locks the door to her bathroom. Scootaloo has already gone outside she can tell by the sound of the back door opening and then closing. Without hesitation, she opens up Scootaloo’s poop smeared diaper and squishes is firmly up against her own wet pussy.

Moaning in pleasure as quietly as she can while smearing friend’s daughter’s poopy diaper all over between her legs, Rarity decides that having a diaper filly around the house will make her happier than she ever realized it could. Scootaloo will be back with her parents the day after tomorrow, but Sweetie Belle, who is already wearing diapers at night and seems to like them, will make a great diapered partner, if only she can get her little sister to enjoy her diapers as much as Scootaloo now does.

She moans even louder at the thought.

Epilogue

**** 1 year after chapter 1 ****

Rarity stared out the narrow bathroom window of her parent’s house with growing interest. Being on the ground floor allowed her to look directly out onto the side yard of the property, it wasn’t particularly wide, and was bordered by a weathered and sun bleached wooden post and rail fence, the kind more commonly found further south in the prairie lands. But beyond that was two hundred meters of open grass and young trees to pass through before arriving at the nearest house, making the property seem considerably larger than it actually was. As pretty as the small yard appeared with its beds of lush hostas and ferns, none of this was what had caught Rarity’s undivided attention.

Just after she had slipped on a cute red thong over her wet diaper and just before a shiny black pvc skirt that barely hid said diaper was planned to be put on, a young filly had appeared outside the window. Rarity had known that Scootaloo was planning on coming over this morning thanks to a quick word from Sweetie Belle, so apparently, she had arrived. Scootaloo, as much as the filly resisted admitting to it, was quite cute, in a tomboy sort of way. She was wearing a pair of light faded denim overalls that looked a size too small to Rarity’s trained eyes and that came no farther down her legs than short-shorts would have. Under that was an even tighter orange t-shirt which Rarity could see ended a good five or six centimeters short of her waist line. The outfit did quite a lot to cause Rarity to reminisce about the kinds of outfits she had Scootaloo wear years ago when she was getting the young filly into diapers in the first place. Scootaloo had her mane cut short for a filly, so it was never more than five centimeters long. It gave her something of a pixie look that Rarity found rather attractive. However, what Rarity found most interesting was the way in which the butt and crotch of the overalls were stretched tight over what was underneath.

A diaper, she could easily tell, and a decently thick disposable one at that. She could see it was disposable because a bit of white plastic was poking up above the side of the overalls. Scootaloo obviously wasn’t too interested in keeping her diaper a secret from Sweetie Belle, or Applebloom for that matter, who had arrived through the front door not ten minutes ago. Rarity hadn’t heard anypony coming through the door since then and could only assume that Scootaloo had just arrived and was heading towards the side yard.

“Why would she go that way?” Rarity mused to herself.

It was much faster to go through the house and Scootaloo knew she was welcome inside anytime. Rarity’s question was almost immediately answered when Scootaloo stopped and without looking around too much, thankfully for Rarity, spread her legs and turned around so her bulging butt faced Rarity. Rarity could see Scootaloo straining slightly and thought she caught a hint of motion, a slight expansion between the legs, under the tight overalls, though it had been hard to tell. Keeping her legs apart but bending upright again Scootaloo proceeded to place a hoof on her crotch and close her eyes. She must have stayed like that for nearly a whole minute before opening her eyes and looking down at herself. She rubbed her crotch a bit and patted her butt, then went over to a small ornamental cement garden bench and sat herself down on it with a little plop. Her eyes immediately closed again and as she smiled she scooted her butt back and forth several times while leaning back with her hooves out behind her, keeping her upright. Rarity knew exactly what the filly was doing and as a result had become quite hard in her own diaper.
When Rarity looked up from her brief glance down to the bulge in the front of her soaked diaper she found herself staring right into the purple eyes of Scootaloo who was looking at her across the narrow yard with a slightly embarrassed expression on her face and a bit of an awkward smile. Before Rarity had a chance to react Scootaloo stood up swiftly from the bench, a slight blush on her cheeks, and walked off confidently towards the back yard while brushing herself off.
