Author's Note

It took wayyyyy to long to make real progress on this story again. I apologize to my readers for not posting anything new in months. But, Faust! my life can be busy. Anyway, worry not! I will be posting even more new stuff over the coming days and weeks, You won't have to wait months more for it.

Ch 2: Friendly Interactions, or, Love in the City

For anypony who had any intention of publicly enjoying their fetishes, even subtly, confidence is a critical trait and its usefulness cannot be overstated. This, Rarity believed wholeheartedly. Having said that though, confidence is not an excuse for taking unnecessary risks or engaging in behaviors that might have unduly unpleasant consequences for a pony’s social standing. This is why she had made two decisions before she and her little sister had left her penthouse before their night on the town. The first had been to get Sweetie Belle to wear a very cute pair of light blue denim short shorts over her new pvc plastic thong and under the transparent plastic of the skirt. The shorts had no back pockets and fitted themselves to her round little butt amazingly well. Paradoxically while revealing less than the thong alone, they somehow managed to make the twelve-year-old mare even more enticing. Rather like a Christmas present with two layers of wrapping. It had been a good fashion decision, the only kind Rarity made anymore these days. Usually.

The second decision was to forego any sort of dress of her own as originally planned and instead put back on the skin tight black pvc plastic bodysuit she had begun the afternoon in. The advantages to this were several. Not only did it look and feel great to walk around in as she strolled down the twisting avenues with the soft warm light from street lanterns and open-till-late establishments spilling over the smooth cobbles and causing reflections to dance across the shiny plastic as she strolled by, but it made her thick diaper visible to everyone in a way that revealed no details about it. Even more importantly the material of the bodysuit went quite a way toward containing the smell. Thus she could be known by thoes who understood what they were seeing as a diaper wearing mare but only the ponies she knew the best would ever get a chance to see inside the bodysuit and know the full extent of her perversion.

An additional benefit was that the tightness of the garment kept the big bulky diaper and its wonderfully disgusting contents constantly pressed firmly against all the important areas inside it. If she had been so inclined Rarity could probably have made herself cum simply by galloping. It felt that good. Though the diaper was so well made that despite now showing a very visible light brownish stain all the way from right under her tail to almost the top of the front it would not have sagged much even without the bodysuit. As it was the diaper could hold its shape indefinitely under the tight pvc.

So this was the state of the two mares as they confidently strode down the narrow shopping street now a block from the ornate stone building whose top two penthouse floors had been witness to all manner of sexual misadventures.

“So, how are you feeling Sweetie?” Rarity asked, deciding she had enough of the attempted small talk and awkward silences she had endured since leaving home. It was time to get the filly a bit more confidant in herself. They turned a corner onto an even smaller side street angling in the general direction of Canterlot Castle itself providing a good opportunity for renewed conversation.

“Uh, I feel nice- um fine, I guess.” Sweetie said still looking around a bit nervously.

“Come now dear, that's not really an answer and you know it. What exactly are you feeling? I know it will make you feel good talking about it. Besides, not many ponies are going to hear you, and the ones who do will probably enjoy what you have to say considering the time and the district we are approaching…”

“You feel sexy don’t you.” Rarity added after a pause, and watched as Sweetie Belle started slightly at the blunt remark.

“How do you do it?” Sweetie Belle said looking up and directly at her big sister for the first time since they had begun walking.

“How do you just go about like this and not feel embarrassed? I mean, yah, ok, you’re right I do feel sexy, I love this outfit! And it makes me, um, well, it feels good between my legs and… and the plastic of the skirt feels good on my fur. But it’s still embarrassing -and I’m not even wearing a diaper.”

“Well, let me say this Sweetie dear, if you didn’t feel a bit of embarrassment about your situation I’d be a little worried. We both know you’re not new to intimacy, but those experiences have only ever been in private with ponies that you know very, very well. Being out in public and being ‘on display’ so to speak is another matter entirely.” Rarity replied, keeping an eye on Sweetie Belle’s dubious expression.

“Keep in mind that I have been doing this kind of thing since I was even younger than you, and all that experience builds a lot of confidence. You can’t be expected to be as sure of yourself as I am on your first night ‘out on the town’. I certainly wasn’t at your age.” Rarity continued.

“Simply remind yourself how good you feel and how happy that pleasure makes you. That enjoyment will ultimately overcome any self-doubt or embarrassment you may have. It’s hard for anypony to make fun of you when you are so obviously enjoying yourself after all!”

“So you’re saying I should just enjoy being myself and everything else will work out?” Sweetie Belle inquired.

“Well, I guess I am, aren't I.” Rarity replied. ‘Wisdom from the mouth of babes…’ she thought.

Seeing her little sister perk up at this confirmation allowed Rarity to relax again, the last thing she wanted was to have Sweetie Belle not enjoy herself on this special night. Rarity hadn’t picked this night specifically, but she was glad it had turned out the way it did. Even though it was still early October the nights were beginning to cool down up here in the mountains. Two thousand meters below them in the Celestial Valley, Ponyville would still be comfortably warm and the trees wouldn’t start to turn for weeks yet. Here though, the aspens were beginning to transform into their characteristic brilliant yellow and the maples were showing hints of fiery oranges and reds. None of this was apparent in the dark and dimly lit, but blessedly clean, alleyway they were winding their way through, but what was becoming visible however, were the occasional decorative pumpkin or gourd collection set out in anticipation of Nightmare Night. Instead of being creepy though, the occasional warm window light and the old stone shops and houses packed so close together made for a very cozy atmosphere in Rarity’s opinion.

Though of course it wasn’t so much the delightfully rustic urban surroundings that had Rarity in such high spirits. The warmth of the slippery mess coating the inside of the diaper currently residing happily between her legs was engendering a second more specific source of heat. That, and watching her little sister’s round butt and slim legs as she walked alongside made for quite the distraction. If there had been any obstacle present in the middle of the street just then Rarity probably would have smacked right into it. She was that distracted.

Fortunately for the both of them, she was so familiar with their destination that her ability to find it was nearly instinctual and it took little to no couscous thought to successfully arrive without incident. The building Rarity led her little sister to was not particularly remarkable, at least by the standards of the neighborhood it was in. Most other districts of the capital, perched at various levels along the eastern side of the Celestial Valley, would have considered the seven story rough cut marble and heat-hardened oak timber structure to be ostentatious and imposing. Here however, only a block and a half from the outermost walls of Canterlot Castle itself where the buildings became ever taller, more expensive, and in some cases quite historic, this particular structure fit right in.

If an enterprising pony were to go to the bother of looking up the building permits, structural application contracts, or even the city residency listings for the old and ornate edifice they would find it to be defined as a residential structure with each floor, besides the ground floor, which was taken over by a collection of high end retailers, laid out as one large, single apartment. Each floor occupied by either some wealthy merchant or various aristocratic family member -the type who wouldn't balk at the ten million bit per unit asking price. All in all, not so different from the building Rarity herself lived in. Though her place had merely cost half of what these flats supposedly went for due to the greater physical distance from the Castle. But Rarity was in no way envious of the residents of this tower or of their posh apartments, because in reality neither actually existed.

The idea had originally been Celestia’s. Whether or not this revelation proved shocking said much about how well a pony actually knew the princess in question.

Rarity had never risked prying into the original legal details too heavily but from what she had uncovered, she knew that around eight hundred years ago, near the beginning of an era of increased population growth and civic expansion that would ultimately lead to the founding of other relatively nearby communities such as Ponyville, there was also the start of an overall decrease in cultural prohibitions on sexual activity in part brought about by Celestia herself beginning to publically display a more liberal attitude, a sign that she was recovering emotionally from the admittedly temporary, yet still long term loss of Luna. This upturn in the number of ponies finding new ways to pleasure themselves and others, inevitably resulted in a dramatic increase in the number of brothels popping up in and around the capitol like so many woodland mushrooms. While the idea of sex for money itself didn't bother Celestia too much, the ponies who came to control the business did, and very much so at that. A new breed of pimps and unscrupulous brothel managers began to acquire money and influence at an alarming rate while at the same time making life increasingly worse for the ponies under their employment. Celestia knew that if she tried to shut them all down she might have temporary success, but sure as shit falls downhill new managers would creep in to fill the gaps and the only thing she would accomplish would be to drive the whole industry underground, and in the process make the lives of the poor mares involved even worse.

So, in an excellently played and completely unexpected move, Princess Celesta pulled off one of the finest instances of ‘If you can’t beat em’, join em’. That Rarity had ever heard of. Instead of shutting down the brothels she quietly took them over, using her political astuteness, myriad of contacts, and vast wealth, she bought buildings, payed off district managers, legalized new forms of business practices, and organized an iron-clad hierarchy of new loyal, honest, and most importantly, caring managers for every brothel in the whole of Canterlot. All of them mares. After all, it was now illegal for any male pony to operate a business that employed female sexual workers. From the point of view of the bewildered and suddenly disenfranchised stallions who had just the day before been making millions with the sexual organs of other ponies, the entire industry had simply vanished from reality as a business opportunity. If they tried to complain, nopony would listen as there was little moral or legal sympathy to go around. If they tried to set up an illegitimate business, nopony would work for them because they could make more money in better working conditions while remaining legally employed having sex under the watchful and caring gaze of Celestia herself. Effectively they were stonewalled no matter what direction they turned in. And as their monetary gains were accumulated from what was for them now an illegal practice they found to their horror that all their business assets and bank accounts had been possessed by the government and the funds and material goods redistributed to the mares who had been taken advantage of, to a variety of charities, or in the case of fancy furnishings, to line the halls and decorate the rooms of the castle and surrounding government buildings. By the end of the week Princess Celestia had become the Madame of the largest and most pleasant to work for sex industry in Equestria’s history. But for the average pony trotting along any one of the smooth cobble streets of Canterlot, not a clue of any of it was to be had.

As so it was, 789 years later, Rarity had gone to the Ministry of Public Welfare office and after a brief interview, had signed her name on a nondescript roll of parchment officially noting her as a public health worker in the direct employ of the City of Canterlot.

Of course, Rarity mused, as she led her little sister down a narrow street and up to a small door painted a deep blue located on the side of the grand structure, that original job would never have payed anything like what her present lifestyle required. But being a leading fashion designer and getting to know (and pleasure) the princesses personally resulted in a not insignificant income.

Pausing at the door Rarity turned to Sweetie Belle.

“By any chance do you know what this building is? Why I’ve brought you here?” Rarity asked.

“Uh, not really… is it a club or something that you like?”

“Hehe, well in a way I suppose your right, but not quite. You’ll see.” Rarity replied as her horn glowed faintly in the darkness of the alleyway, lifting a large brass knocker bolted to the middle of the door.

Rarity privately enjoyed her sister’s slight confusion at how she knocked on the door precisely once and then waited patiently a few seconds before the thick door slowly swung inwards silently with nopony visible on the other side. All very dramatic she thought. Typical of the ponies who had originally set this place up so long ago.

“Come on then dear, in we go!” Rarity said, smiling back at Sweetie Belle who was staring down the dim corridor, lit only by a few deep red light bulbs attached at regular intervals along the walls.”

Rarity had to admit, she didn’t remember it looking quite so spooky the last time she had visited. Perhaps they were toying around with another Nightmare Night theme. Wouldn’t be the first time, she mused.

“No need to be afraid darling, believe me, this is actually one of the safest places you can find in the whole city. After all it’s not unusual for one of the princesses to come here.” Rarity said watching Sweetie Belle’s face change from a dubious expression to one of hope and curiosity at the mention of an Alicorn.

“You never know, one of them might be here tonight.” She continued.

That seemed to do it, with renewed confidence Sweetie bounced up the two steps leading to the door and came in alongside her sister.

It wasn’t long after Celestia’s private coup in the world of physical delights, that she realized that having the Castle itself being used as the headquarters of every brothel within the kingdom might lead to some awkward difficulties. No, that wouldn’t do. Not at all. Which is why, under the pretext of building a new seven story condominium tower right next to the castle for the ultra-rich, the Highgarden real estate company, secretly owned by the Crown, commenced construction of Celestia’s new Sex Workers of Equestria headquarters building. A name that would only ever be printed once, on one scroll, and then sealed away permanently. Every other pony who ever saw it would have no idea what it was ever called or even what its official address was.

It wasn’t until after meeting a certain violet unicorn that she was privately informed by Celestia of the building’s existence and that she might well find herself a highly respected position there if she were ever to pay a visit.

The very building that she was now leading her little sister deeper into.

Rarity did her best to remain silent as she trotted down the hallway, sister in tow, towards one of the main stairways that would lead her all the way to the top floor. The prospect of climbing fourteen flights of stairs was always a bit frustrating to her, but the building had been built well before the mechanical elevator had been invented and as such including one would have required quite the remodeling effort. Something not looked favorably upon by thoes who wished to limit the number of ponies who knew the true purpose of the facilities contained within as much as possible.

However, Rarity admitted to herself, there were two benefits to the stairs. The first being simple good exercise. The second was that the act of climbing stairs in her messy diaper would prove...enjoyable. Especially as her cock had begun to harden again at the prospect of arriving at her destination.

So, up she went, feeling her hardening dick squishing further into the warm semi-liquid gooey poop spread around inside her diaper. The tight shiny catsuit making sure the diaper was held tightly in place. The same slimy mixture was being spread liberally over her pussy lips at the same time making it difficult to not moan the farther she climbed. All the while the more rational part of her mind was enjoying the idea that her little sister was currently able to enjoy the sight of her diapered backside as they ascended.

They encountered their first pony on the landing between the fourth and fifth floor. She was a unicorn, still the most common race to be found in Canterlot, and seemed to be angling for a mild goth look. Her light greyish blue coat and dark navy blue mane, almost a very deep purple, certainly helped that look along. She wore an extremely thin purple thong and socks on all four legs that matched her skimpy choice of underwear in color if not fabric type. A black leather choker and black eye liner completed the simple yet effective outfit. Rarity had seen the mare once or twice before, though she had been a member of The Organization for only a year or two. If Rarity recalled correctly she had a sister her own age.

“Hello, Moonlight.” Rarity said softly with a quick smile as she and Sweetie went past, praying to Faust the whole time that she had remembered the pony’s name properly. Perhaps in keeping with the moody goth character the mare didn’t reply with words but simply speared Sweetie Belle with a predatory grin that would have done a Griffon proud. Sweetie Belle for her part flinched slightly while trying not to do a double take.

Were those teeth…sharpened?

Sweetie hurried off after her Sister with the fur along her back standing on end.

A minute later Rarity, now slightly winded, arrived on a wide landing at the top of the stairs in front of a wide set of double doors made from some hard wood of great age. Centuries of polishing had resulted in a deep gleam off the smoothed surfaces. The doors themselves were inlaid with finely detailed reliefs that when properly examined showed a multitude of ponies, most of them mares, engaged in a great variety of sexual acts.

Finally, Rarity turned to Sweetie Belle and spoke to her.

“What you are about to see may surprise you to a greater or lesser extent depending on who has decided to drop by this evening. But I rather think you will not be too shocked seeing as we have the relationship that we do. And just remember everypony will be quite happy to see you here, I assure you.”

Rarity was pleased with her sister, despite feeling obvious trepidation she was remaining calm and quiet. Well, quiet at least. Turning back to face the doors she channeled energy into her horn and lowered her head until the tip was aligned with a hole in the door’s lock conveniently just wide enough to accept it. As soon as the magic contained within the lock was satisfied that it recognized the magical field being inserted belonged to a pony it knew and trusted, a couple of dull thuds emanated from within the door itself as the locking mechanisms disengaged.

The heavy doors swung slowly inwards to reveal…a small vestibule.

Sweetie Belle silently puffed out her cheeks in minor exasperation behind her older sister at the anticlimax but quickly came forward as Rarity ushered her in to the small space while the outer doors began to swing shut. As soon as they had the lighting of the vestibule changed from the dim red that had been all pervasive in every other part of the building they had come through so far to a much more comforting warm yellow-orange glow. Only then did the plain inner doors swing outward without Rarity having to do anything at all.

She immediately knew they were in luck.

More ponies than she had been expecting occupied the room. Her gaze was instantly drawn to the centerpiece of the action. Right in the middle of all the expensive oak paneling and trim and the high backed furniture upholstered in what she dearly hoped was fake red leather was Princess Cadance clad only in a pvc bodysuit not unlike the one Rarity had on but colored a light pink. Cadance was hard at work fucking Twilight Sparkle with long powerful thrusts of her glistening cock, whom she had bent over what looked like some sort of cheap inflatable bean bag like object made of soft bright green material utterly at odds with the decor of the large yet cozy feeling room. There was a thick and heavily wet disposable diaper laying open on the floor between Twilight’s rear legs. It was easy enough to surmise that it had been doing its job as Twilight’s personal bathroom right up until Cadance had decided that what lay buried under all that warm wet padding was more important.

Rarity had seen enough alicorn sex by now that the sight, as beautiful as it was, could no longer hold her transfixed if she didn't wish to be. And though the ongoing spectacle of raw Princess into Princess action was certainly hard to resist, there was another pony among the dozen odd others in the room, some she immediately recognized, some not as easily, that caught and very much so did hold her attention.

Fluttershy was sitting slumped down in one of the oversized high backed chairs in the back left corner of the room not far from the large marble fireplace and the merrily flickering fire therein. She had on only one thing, a very thick and very wet disposable diaper. She was staring at the two rutting mares in the middle of the room with a forehoof slowly rubbing circles around the front of her diaper and a somewhat glazed over expression on her face. If she had noticed Rarity and her sister’s arrival she hadn’t made any sign of it. Watching the yellow pegasus enjoy herself in such a manner with a dozen other ponies around her said much about how friendly and accepting of a place this was, assuming you had the right connections to know about its existence at all.

Rarity knew that this was not the first time Fluttershy had been here because she had been the one to bring the shy pony here in the first place a few years back. But this was the first Rarity had seen of Fluttershy coming here on her own without Rarity leading the way. She smiled at herself, seeing that Fluttershy was obviously working on independently expressing her sexuality. Always a good thing for a mare to work at.

Despite her concentration of Fluttershy, Rarity was distracted by a scream and a groan as Cadance came hard deep inside Twilight. The smaller alicorn shuddered as pulses of hot cum splashed into her and Cadance strained hard the whole time burying herself into her partner until nothing of that glorious dick could be seen. Rarity wasn’t sure she could take Cadance herself. That pony was…large. Twilight could, only just, and she was physically a bit larger than Rarity.

A spray of clear mare cum erupted out around the base of Cadance’s shaft, while the last of Cadance’s own was released, as Twilight came. Cadance slowly withdrew herself the tight muscular passage allowing the full length of her glistening shaft to be revealed to Rarity. A thin strand of something clear and sticky bridged the gap between the stiff head and slick pussy lips in front of it for a second or two before breaking into droplets. Twilight slid sideways off the green cushion to plop unceremoniously onto the floor breathing heavily with a look of bliss on her eyes. Some of the surrounding audience even clapped a bit. Rarity had to smile at that, the Princess of Love was a force to be reckoned with when she was horny. Cadance bent low and whispered something unintelligible into Twilight’s ear, which twitched, and made Twilight look up at Cadance and quickly lick her nose. Twilight grinned at Cadance’s startled expression. Rarity for her part had to look away for a bit while stifling a laugh.

When she looked back, Cadance, horn aglow, was busily taping Twilight back up in the diaper she had been wearing before things had gone all hot and heavy. Rarity was not particularly surprised that she instantly recognized the brand as it was from her luxury Padded Fillies line of teen and adult disposable diapers. The one Twilight had on was white down the center with the leg guards and sides colored blue, green, and pink in the style of Princess Celestia’s mane. Or rather, it would have been white but for the obvious heavy wettings the diaper had soaked up. Rarity was pleased to see that despite swelling to nearly twice its original thickness by all the warm urine, its padding was holding together perfectly and the tapes had been pulled quiet tight with no noticeable sagging. Even after having been taken off at least once. A diaper worthy of an Alicorn, Rarity thought.

And Twilight did look spectacular in it. The soaked bulk was gracefully hugging that toned butt and athletic body. Twilight was in amazing shape for a pony so nerdy. Rarity chided herself for the stereotype comparison, but really, it was sometimes difficult to associate this pony with the same one who once lectured to her for half an hour on the implications behind quantum to classical information decoherence before realizing her audience of one had no idea what was being said.

“So? What did you think?”

Rarity jumped at the sudden and unexpected intrusion into her reminiscence.

“You looked like you were enjoying the show there, though of course so was everypony else…” Cadance continued with an almost private smirk.

“Oh! You were amazing, and so was Twilight at that! It’s not just anypony who can impress me that way. Ah, I wasn’t aware you were in town so to speak, you seem to be here more often than you used to.” Rarity said with a hint of inquiry in her voice.

“Hm, yes, well the Empire is so much more stable than it used to be, and Shining does so love to play at being a prince…Really though, the country practically runs itself so far as day to day concerns go. I know I’m the ruler and all, but my role is more figurehead and ambassador now than it was before.”

“Did you know we’ve gotten so much better at learning how to grow Chrystal structures, thanks in part to Twily there? The Chrystal Palace isn’t even the tallest structure in the city anymore! Just think where we’ll be in a few more decades!”

Rarity had to smile at that, even in a place like this, even just after having hot sex, Cadance’s enthusiasm for the small but swiftly growing nation she ruled over shown through like the sun.
“Really! I had no idea! And it’s only been a year since I visited. I really should do something about that. It’s just there’s so much to do here every day, time just seems to slip by. Well, you know how it is.” Rarity said looking a little embarrassed.

“Oh, don't worry about it, I’ll arrange a trip soon for the both of us then. We’ll work out something, it’s as much my fault for not having any plans myself. But, for the moment…I’m more interested in what you’re wearing, Rarity. Cadance said changing the subject in a way Rarity was half expecting.

“You know… about that, what we’ll get into might not be for everypony here, perhaps a private room would be better.”

It wasn’t that Rarity was trying to hide her diaper from all the other ponies, it was more a combination of understanding that opening up her diaper in its current state might not be agreeable to everyone in the room and also by hiding herself away with only a few mares she enhanced her image as a more exclusive pony who didn’t just put on shows for free to everyone. Not even here. Let the other ponies use their imaginations! She though, that way they would be even more eager to see her perform in the future.

“Oh, that nasty huh? I thought I smelled something coming from over here…” Cadance said nearly giggling.

“One of the side rooms should do nicely then!” Cadance said turning towards a door on the right side of the lounge.

“Ah, Cadance, there was actually somepony I’d like you to see.” Rarity had to say quickly before Cadance rushed off.

“Who is that, is it Sweetie Belle? Did she come here with you?”

“Yes, actually! I know you two have met before but it’s been quite a while. I thought, well, she’s twelve now you see, and quite old enough to take part in certain activities now, so…” Rarity trailed off.

Cadance smiled brightly at Rarity. “Well of course! Do you want her to watch us then?” Cadance asked with a grin.

“Hehe…well more than watch actually.”

“Oh really…that will be fun then. Does she have much experience?” Cadance asked.

“From me yes, and probably from Applebloom- her marefriend, but not any other ponies that I’m aware of.”

“Thank you for bringing her here then! I consider it part of my duties as Princess of Love to help instruct fillies in the ways of pleasure. So, I have to ask then, you, and her, and…messy diapers? Cadance asked hopefully.

Rarity had the presence of mind to seem slightly sheepish. “Yes, on several occasions. Actually just a few hours ago in fact.” Might as well be honest Rarity thought.

Smiling while raising an eyebrow Cadance turned to regard the filly, who Rarity now saw had taken it upon herself to go over to talk to Fluttershy, who seemed slightly embarrassed to be seen in such a place by a filly from her own town. Though Rarity suspected that thoes feelings were superseded by seeing a filly from her own town in this place to begin with.

Sweetie Belle for her part seemed to be chatting away quite contentedly, apparently happy with being able to find a familiar face in this new environment. A few of the other mares were eyeing her quite openly. Obviously considering what fun could be had with a sexy filly in a sexy outfit. Rarity was privately smug that Sweetie Belles clothes were sexier than the majority of the other mares.

The two of them trotted over to the corner where Fluttershy had now gotten up from the chair and was standing between it and the fireplace. Rarity had fun watching the procession of emotions running across the Pegasus’s face. First came surprise at the new attention from both ponies, then embarrassment and a quick backwards glance at her diaper, then a blush and an almost hopeful expression as her mind computed what was likely to occur over the next several minutes considering the place and the ponies involved.

“Fluttershy! Darling, I’m so glad to find you here! I would’ve come straight over but I was rather distracted by the activities on display you see.” Rarity said in as much gentile happiness as she could convey as she gave the yellow pony a hug and a quick kiss on the cheek.

“Oh, Rarity, I’m glad too, it’s so nice to be here with friends…I don’t know if I would have come myself if I hadn’t known Twilight would be dropping by this evening. If you don’t mind my saying so you, um, look very nice in your outfit. I assume there is a diaper under there as well? Fluttershy said glancing quickly at Rarity’s flank.

“Why thank you! And yes, I am diapered, how could I not be with such promises of fun to be had on a night like this. If I may say so, your own diapers look fabulous on you! They fit you perfectly and well, the wetness makes the diaper go well with your coat color, its practically a fashion statement in of itself!”

“Goodness! Um, if you say so Rarity.” Fluttershy said blushing, but looking quietly pleased with herself.

“I uh, do love this diaper, it feels so, so very good on me. And it’s nice not having to go looking for a bathroom all alone in a building like this. Thoes hallways…” Fluttershy said with a slight shudder. Rarity smiled at her friend, Fluttershy would use that as an excuse to wear a diaper. Though to be fair, perhaps in her case it wasn’t always so much of an excuse.

“So Cadance and I, and perhaps Sweetie here are going to take a little trip to the side parlor for a bit more fun and we were wondering if you might just be interested in watching or even… maybe getting involved? After all, you did seem to be enjoying that diaper earlier when we came in.” Rarity couldn’t help herself from adding.

Fluttershy, looking embarrassed while rubbing one foreleg against the other did manage to nod vigorously in the affirmative.

“Oh good that makes three then, by the way where did Twilight go off to? She was here just a minute ago.” Rarity asked, looking around.

“I think she went back to the castle,” Cadance replied, “she mentioned something about having some further study project to attend to there.”

Rarity had to work hard to not roll her eyes at that, though…on second thought, Twilight was just sneaky enough that maybe this time “study project” didn’t exactly mean what it normally would have. Now she was having to work hard at not smiling while contemplating exactly what kind of “project” she was “studying”. Rarity considered that perhaps a late night trip over to the castle may well be in order, assuming everything went well here first. After all, she could hardly allow the Princess of Friendship, and her good friend, to get away with those sorts of clandestine activities without her at least knowing something about it. But first things first, there were ponies counting on her in the here and now and it would take her full concentration to not disappoint them. Twilight and her nocturnal activities would just have to wait.

“So, Rarity, is this sexy little filly standing here Sweetie Belle? She really is something!” Cadance said smiling at the filly.

Rarity had to roll her eyes at herself, how could she have become so distracted by Fluttershy that she had forgotten to introduce her own little sister. ‘For shame’ she silently chided herself.

“Goodness yes, Sweetie Belle? This is Princess Cadance, you remember meeting her a few years back don’t you? If nothing else, I know you were at the wedding ceremony.” What a lot of overly politicized bullocks that was. Rarity added to herself.

“Oh yes, of course I remember, you were so beautiful! I mean, you still are of course!” Sweetie Belle added hastily, blushing, and remembering enough formality to bow slightly.

Rarity had to wonder if formality had any meaning left in a place like this.

“Why thank you, Sweetie Belle. I think you are beautiful too. In fact, I think you’re rather hot. May I kiss you?” Cadance asked.

Rarity was amused by watching her little sister’s mind desperately hurrying to catch up with this sudden intensification to the conversation.

“I, uh…yes! Um, please?” Sweetie Belle managed to squeak out. Cadance laughed softly and lowered her head down and immediately locked her lips with the filly. It hadn’t taken but two seconds before the ponies were making rather erotic sounds as their tongues fought for dominance. Cadance soon followed up by pressing a hoof under Sweetie Belle’s skirt and onto her soft round butt. Just as the filly began to moan, Cadance broke off the kiss and pulled back her leg.

“So then, weren't we going to have a bit of fun with whatever it is Rarity is wearing under that hot outfit she has on?” Cadance asked directly to Sweetie Belle.

“Perhaps we will continue our little session afterwards?” She continued, still addressing the filly.

Wide eyed in admiration all the star-struck filly could do was nod.
