RalphKenneedy756 contacted me some time after the prequel of this story was published, wanting to do a story about Moondancer's birthday party at The Fountain of Youth. We worked together on it, and eventually I published it on Fanfiction.net. It is the same story that is now being brought over to you here.

I would strongly recommend you check out the unofficial prequels to this fic's prequel first, so as to get a better idea of the setting and universe this takes place within. It's not an absolute requirement, but familarity with them will go a long way towards explaining things you might not otherwise know.

When I did the prequel a year ago, I was unaware that "Photo Shoot" had a sequel. After learning about it, I knew I had to incorporate that sequel's events into here.

Birthday For a Big Foal

Moondancer was feeling giddy, full of excitement! This was going to be a birthday party to remember for sure. She still couldn’t believe her stroke of luck in getting her friends to agree to hold her birthday party at The Fountain of Youth, but they’d all agreed while apparently suspecting nothing. Even Minuette (who had confirmed that she was indeed an adult foal) had no idea what the club was or what it involved.

Boy were they going to be in for a big surprise! After all, there was a reason why The Fountain of Youth was an underground club. For its clientele, the fact that it was underground was important and very reassuring. Nopony who worked there or attended there openly admitted to knowing anything about it, but it’s not like they denied its existence either. You just needed to know the right ponies in the right circles.

The club owner’s, Pacific Glow, had been all too happy to allow Moondancer to book a reservation in advance that involved the VIP experience. “I’ll make sure the entire club knows about your little birthday gathering,” She’d told the unicorn with a smile and a wink. “We might just have to do something extra special for the occasion.”

“You mean, besides a shoutout from DJ Pamps?” Moondancer had questioned.

“Yes, besides that,” Pacific Glow had replied. “We’re still working out the details of the VIP treatment and what to do for special guests. In fact, I’m kind of hoping to hire a few more ponies. I’ve heard about some possible ponies of interest in Ponyville that might be a good fit for the club.”

Moondancer had just smiled. “Well, I know a friend who might be willing to help with the club a little. But I’ll have to talk it over with her first once she’s had a chance to see everything that makes this club special.”

And so it had been arranged. All of Moondancer’s friends had replied, even Lyra, with whom the group had indirect contact with. The days leading up to the big birthday bash then passed quickly. Before anypony knew it, the day (or night rather) of the party arrived.

Moondancer was all too happy to take the lead on that night, taking her five friends through the heart of Manehattan until finally coming to a rather unsuspecting looking building. It hardly seemed distinguishable from the countless other plots of land to either side of it. But of course, it was what was inside the building or more specifically underneath it that was important.

The unicorn with a creamy yellow coat adjusted her glasses and plucked up courage as she led her friends inside and down the staircase leading to the club. “Uh girls,” She suddenly hesitated, realizing that she likely should’ve talked this over with them in secret a little bit sooner, just in case any of them might have second thoughts or want to back out. Alas, it was too late now. “There’s something you probably should know about the club. There’s a reason why it’s underground and why its usual patrons are… secretive.”

The four other unicorns and the lone alicorn all blinked in confusion, and Twilight took the liberty of asking the nagging question on everypony’s minds. “You mean there’s a dress code or something? You didn’t say anything about a need for formal attire.”

Minuette only sheepishly replied by shuffling her hooves. “I don’t think it’s formal attire that’s the issue. An underground club wouldn’t be so uppercrust. I think it’s something else about the dress code. And if I'm right, I know what it is.”

Moondancer then plucked up courage as she brought a hoof up to the door leading to the club proper. “Maybe it’s better to show you rather than try to explain it. Just… don’t freak out or anything. I already booked an experience just for us, but I’ll understand if some of you might wanna back out.”

And then the door to the club was pushed open. The circle of friends trotted in, with only Moondancer truly aware of what they were about to see. “Welcome… to The Fountain of Youth!” She declared in grand fanfare as she waved a hoof. The looks on the faces of her friends was that of stunned silence!

It took a while for the shock to wear off and for the five friends to realize that what they were seeing was indeed real. The Fountain of Youth was truly a club like no other.

The entire floor of the club was covered with a soft but pale colored pink carpet. It seemed like one’s hooves practically sank into it if one didn’t try hard to keep them from doing so. Pink and white striped wallpaper adorned with red hearts lined every wall and even the ceiling, creating a gentle and relaxing atmosphere. Stuffed animals lined up against the left wall in a variety of sizes, with a few clumsily scattered about the entirety of the club.

The main dance floor had all the usual trappings of a dance floor, despite the carpet that covered it. And beyond it, at the back center of the club, was the stand for the DJ. A stand surrounded by large pink bars that made the stand look more like a make-shift crib. And this was despite the very hi-tech sound equipment that was unlike anything seen at any other club, it was even set up in a way that the DJ on duty had no need for earplugs or noise cancelling headphones.

There was a bar not far from the dance floor and DJ stand, which would’ve probably blended into the background if not for two features: One was the mesh netting like buffers that blocked off either side of the bar, requiring one to straddle over them to reach it. And the other was that instead of bar stools there were high chairs, including a set of six finely polished ones that had a sign on them saying “Reserved”.

Last but not least was a set of brightly colored change mats at the opposite end of the club from the bar and just off to the side of the main dance floor. Accompanying them was a large, wooden supply cabinet and two giant trash cans. There was little doubt as to what any of those were for.

In short, The Fountain of Youth was made to look like a giant nursery. And any doubts about that could be quickly erased when one saw what everypony in the club was wearing, not just the attendees but also the club staff: Diapers. Heck, some had pacifiers dangling from strings and others wore colorful onesies that barely covered up their padded postures. The sound of crinkling could be heard everywhere, even above the loud music and the sound of ponies doing what they normally did at clubs.

“Hi, welcome to The Fountain of Youth!” A light pink coated earth pony with a pacifier dangling from a string around her neck greeted. She strolled over to greet the gathered party, apparently unconcerned that she was blatantly padded for all to see. “My name’s Pacific Glow,” She extended a hoof in greeting. “I’m the owner and the manager of this place. You must be the friends of Moondancer, the birthday girl.”

Minuette smiled as she shook Pacific’s hoof. “Yes we are. Oh, I can’t believe I never heard of this place before! You’d think it would be all the rage in the adult foal world.”

Pacific blushed and “glowed” brightly. “Well, we’ve only just been set up for about a month or so at this point. We aren’t as well established as some of the bigger clubs like this: We’re certainly no Royal Canterlot Kindergarten or Pamp My Flank.”

“Oh, I’ve heard stories about them!” Minuette cheerfully beamed. “And there’s also Crystal Cuddlers, Forever Filly and Little Pilots. It’s really too bad there’s nothing in Ponyville, that feels like a prime market for a club like this.”

Twilight then saw fit to ask. “Wait, how do you know all of that, Minuette? If this club is so underground that even you didn’t know about it, how the hay could you know about other clubs like this?”

The aqua blue coated unicorn with a toothpaste like mane and tail blushed a bit as she decided to confess. “Well, there’s something you probably didn’t know about me before. I’m… well, an adult foal model. Have been for a long time. I’m actually pretty famous in the adult foal world for all the magazines I pose for.”

“No way!” Twinkleshine gasped as her eyes widened in surprise! “Here I’ve always wanted to open my daycare and care for foals, and you mean to tell me that you’re basically a foal but all grown-up?! I could’ve been getting in tons of practice by this point if I’d known!”

Twilight proceeded to speak up. “‘Adult foal’ huh? I believe I’ve read about that somewhere before, can’t remember where,” And she then commented to Minuette. “I guess it’s no surprise you would have that… interest. You always were the most child-like among us, even when we were fillies.”

Minuette smiled and swished her tail. “Well, I’m not the only one who’s been living this secret life,” To Moondancer she then declared. “I think it’s time you came clean about your intentions, and about why you insisted on us celebrating your birthday here.”

This was it, the moment of truth! Moondancer knew that sooner or later a conversation like this would have to happen. So, summoning up all the courage she could muster on such short notice, she looked her friends deep in the eyes and admitted. “Girls, I’m an adult foal too. Have been for a while now. Maybe not as long as Minuette, but long enough to really feel comfortable being one. And this club here… it helped me to feel more secure about being one.”

The glasses wearing unicorn just stood there in silence as her words slowly sank in. She knew Minuette would have her back no matter what, but how the rest of her friends would feel was a complete mystery. Would they really accept that their friend, one they’d known since they were just fillies, liked to dress up like and act like a big foal? To wear and even use diapers for their intended purpose?

Ultimately, the silence was broken by none other than Lyra Heartstrings, who was the first to find her voice. “What exactly brought on this interest? Does it have something to do with your childhood?”

“You… aren’t mad or upset about my confession?” Moondancer nervously questioned. “You’re really okay with… the diapers and everything? Even knowing what they’re for?”

Lemon Hearts nodded. “It is a lot to take in, admittedly. But that doesn’t change the fact that you’re our friend. After everything we’ve been through, you think something like this would tear us apart? Even if we may not all agree with it or fully understand it, it doesn’t mean it has to come between us. If you still wanna be friends with us, we’re happy to still be friends with you. And with Minuette if she’s also one of these big foals.”

“I have to agree with what the others have said, Moondancer,” Twilight spoke up as she draped a wing over her friend. “It took a lot of courage to open up to us about this, just like it took me a lot of courage to realize I wasn’t a good friend to you when we were fillies. It’s not surprising that you might develop an interest like this, wanting to go back to a simpler time when you didn’t have to worry about things.”

Twinkleshine then declared. “We’re here now, as friends. And this is what friends do for friends. It doesn’t seem like being an adult foal has any negative effects. You’re still the same Moondancer we all know and love, and the same holds true for Minuette. We’ll just have to do our best to accept the fact that you two are a part of this unique culture.”

“See, Moondancer?” Minuette chirped. “I could’ve told you the girls would understand. So throw those troubles away, leave all those big pony worries behind! We’re here tonight to have some fun, and diapers just happen to be part of the process. I for one wouldn’t miss a party like this for the whole wide world of Equestria!”

“Oh girls, thank you! Really!” Moondancer smiled as she hugged all her friends tightly. “You don’t know how much this means to me! And I’m sorry for not being honest with you up front. I just wasn’t sure if you’d agree if I told you what tonight would involve.”

Pacific Glow simply twirled her pacifier around as she spoke up. “Well, not that I mean to interrupt this touching moment, but if the six of you are going to have Moondancer’s birthday party here, you’re going to need to get changed into proper club attire. After all, we do have a bit of a dress code.”

Minuette only giggled. “Oh of course, silly us! Here we are talking when we could’ve been spending that time getting all padded up!” And she all but leapt into the air! “Come on, girls! Let’s get fitted for the evening! This is sure to be a birthday party to remember! Trust me, the diapers are the best!”

And so the five unicorns and the young alicorn were led by Pacific to the back of the club, to a part of the club that usually only the staff got to see. It was a lounge, albeit one that was massive and had the same foalish decoration theming to it as the club proper. It had a well worn, velvet-red couch that had seen better days giving the hoof markings on it. In the center of the lounge was a mini-fridge that seemed fully stocked. And there was an unlit closet all but bursting with foalish outfits and onesies.

The show stopper, however, was the massive plastic changing table. It was all sized up for the biggest of big foals, it looked like it could even support the weight of an alicorn princess or two. It had a lovely bright baby blue coloring to it, and had several drawers that included one filled to the brim with diapers in various packages of packed padding.

“Now then,” Pacific smiled while her guests took in the sights surrounding them. “Who would like to be first?”

Perhaps unsurprisingly, Minuette was the first to volunteer. She practically bounced over to the changing table and lay down upon it. “I hope you have some good brands,” She told Pacific as the earth pony approached. “As a diaper model, I can be very picky about what brands I wear.”

Pacific simply replied. “I think you’ll find our selection to be the finest in the land, something for even the pickiest of adult foals: From super absorbent, to extra poofy, to just plain white for those just dipping their hooves into the water.” She quickly settled on a tried and true classic: A Silly Filly adult brand custom deluxe in large size. And it wasn’t long before she taped the diaper up around the unicorn’s rump.

When the diapering job was done, Minuette hopped down from the changing table and wiggled her padded plot around. “Ah yes, good old Silly Filly. You really can’t go wrong with them.” And without even being prompted to, she wandered over to the closet to pick out a onesie to go with her new wardrobe.

“Guess I’ll go next,” Lemon Hearts volunteered while hesitantly trotting towards the changing table. Even though she wasn’t wearing a diaper, she was still waddling about in a clumsy fashion. “You know, it’s funny. If not for how well read Twilight was, I’d probably have been the first among our group to be fully potty trained. And for years I was proud of that fact. Never imagined I’d be getting back into diapers.”

“Well, there’s a first time for everything!” Minuette giggled as she waddled out of the closet with a onesie almost the same shade of aqua blue as her coat. It had cartoon ponies stitched all over it to give it the feel of a sized up sleeper, even down to the little zipper hatch to make diaper changes easier.

One by one, Lemon Hearts, Lyra, Twinkleshine and Twilight were all promptly padded too. Lemon Hearts favored a brand with built in wetness indicators that took the form of little smiling faces that would fade to frowny faces, and she took a cream yellow onesie that barely covered her rear so that she could easily tell if and when her diaper needed to be changed.

Lyra was given a diaper that had musical notes printed all over it, even on the seat and on the tapes. Her onesie was similarly musical themed and was the same golden yellow as the lyre depicted on her cutie mark. “Bon Bon would never believe me if I told her about this!” She giggled. “Although, maybe she could come here if she ever needs to do some ‘undercover work’.”

Twinkleshine got a plain white diaper with nothing special, and picked out a pink onesie with a similarly plain design that effortlessly covered her diaper up (aside from the obvious bulge in the back). Just walking around proved to be a challenge for her due to how much her legs were pushed apart. “This is gonna take some getting used to.” She admitted with a raging blush on her cheeks.

Twilight decided to get a special limited-edition diaper made by Crinkle Clouds that allowed the user to manually adjust the poofiness: Either with hooves or with a magic spell. “I wonder if there’s an optimal amount of poof and crinkles: Not so much that you can’t walk or move, but not so little that it’s like you don’t have a diaper at all,” She explained to the others as she was then delighted to find a lovely night blue colored onesie with yellow stars and moons stitched onto it. “This looks just like my Starswirl the Bearded costume!” She exclaimed! “Oh, I wish I would’ve thought to bring Smarty Pants with me! I’ll have to remember her for next time if we ever do something like this again.”

Moondancer was thus left as the one to get padded up last. But that was to be expected since she was the birthday girl. It had been her idea to come here, and she’d signed up for the VIP treatment. So she knew what was coming next.

Yet even the cream coated unicorn could not have anticipated what was presented to her! It was an obvious jumbo sized diaper package in lime green coloring. It was so big it was a miracle it had fit into the drawer from which it had been retrieved. It was placed on the ground with a thud, drawing attention to itself!

And the diapers inside of the package were extremely colorful: Hues of yellow, blue and pink that looked as if a foal had been painting them on with the way there seemed to be no pattern at all. Then there were the little things stitched all over the padding, even the tapes and the seat: Little suns, moons, crystal hearts and six pointed stars. The inspiration seemed painfully obvious.

Pacific explained to all. “This is what we have for VIPs, it’s the Super Royal Deluxe Padding: Padding fit for a princess. I know they must seem really big, but believe it or not they’re not misleading when they say ‘One size fits all’. You just put them on and… well… you’ll see it with your own eyes soon enough.”

“Hey, wait a minute!” Twilight all but gasped when she saw the diapers. “Why do these diapers have the same colors as Princess Celestia, Luna and Cadence’s magic? And why do they have their cutie marks as well as mine? I don’t recall ever being told about this.”

Minuette laughed and kicked about in her pampers, sending up a shower of foal powder in the process. “Oh Twilight, of course you didn’t. Haven’t you learned yet that being royalty means your face and likeness can be used for just about anything? You obviously signed the paperwork agreeing to let diaper companies use your likeness for their brands.”

“W-well, yes,” Twilight admitted with a blush and a look of embarrassment. “But I just thought they were meant for little ones. You know, like actual foals. I didn’t think they’d use them for… bigger foals.”

“It’s alright, I don’t think any less of you or the other princesses for it,” Pacific Glow reassured the young alicorn. “Besides, I’m sure Princess Celestia and Princess Luna know about Royal Canterlot Kindergarten, and Princess Cadence knows about Crystal Cuddlers. Kind of hard to set up shop in Canterlot or the Crystal Empire and not have the princesses know about it. Obviously, nopony thinks any less of them for knowing about our interests.”

Moondancer then encouraged. “If it makes you feel better, Twilight, I know a few ponies who saw this padding and didn’t even bat an eye at the princess theming. Ponies come to places like this to have a good time and forget about their troubles. Besides, shouldn’t the birthday girl get only the best that a club like this has to offer?” She promptly lay down and told Pacific. “I’m ready when you are.”

“Okay,” The earth pony grinned and smiled. “All of you better watch closely, don’t even blink. You are NOT gonna believe what you see!” In a matter of seconds she had the padding taped up around the unicorn all nice and snug. Then she helped her charge up, watching as the unicorn struggled to get her bearings due to the massive weight underneath her.

And then, before everypony’s eyes, there was a faint glow of magic the same colors as the auras of all the alicorn princesses (the fully grown ones anyway). It faded as quickly as it had arrived, and when it had done so the padding had now shrunk considerably so that it now fit Moondancer perfectly.

“Ah, the Super Royal Deluxe Padding. Still can’t believe how lucky we were to stumble across it,” A voice familiar to Pacific (and to an extent Moondancer) but unfamiliar to the rest called from the other end of the room. “Between it and the hiring of DJ Pamps, this club has been practically swimming in bits.”

All eyes turned to see an earth pony mare of medium build standing before them, wearing a thick, white diaper that she seemed to have no trouble trotting about in. Her coat was a pale, light grayish mulberry pink in color, her eyes were a modest shade of purple, and her mane and tail were somewhat bushy in style and sported locks a pinkish-raspberry in color. Her cutie mark depicting grapes and a strawberry could be seen even with the diaper she had on her.

Pacific happily gestured a hoof as she proudly introduced to her guests. “Everypony, meet our bartender: Berry Punch. She was the first pony I hired after I opened up this place. Without her help, I wouldn’t have a club at all.”

Berry only replied while swishing her tail. “It was nothing, really. Pacific needed a bartender and I needed a job, so it was beneficial to both of us to go into business together. Honestly, the wardrobe requirement wasn’t that bad once I got used to it. No more having to worry about toilet hunting with half a dozen or so other ponies all competing for the same thing.”

“You need something, Berry?” Pacific said to her fellow earth pony as she trotted over for an abrupt diaper inspection. “Nope, still dry. Is the bar out of stock? Do we need to empty out the trash cans?”

Berry shook her head. “Nah, everything’s fine. Just figured you should know that DJ Pamps is here, fashionably late as always. But hey, at least she’s embracing her reputation around here,” Then she looked at Moondancer and what the unicorn was wearing. “I take it this is the VIP for that birthday party you told me to reserve seats for, Pacific?”

The pacific on a string wearing earth pony nodded. “Yes: She and her friends. By the way, her name is Moondancer.”

“Ah, Moondancer,” Berry seemed to smile. “Splendid to see you again. You’re becoming a club regular at this rate,” She bowed her head and then said to the others. “Well, whenever you’re ready for the big birthday bash, just swing by the bar. I’ve got everything all set up: Cake, party favors, party hats, you name it.” And then she strolled away with the greatest of ease, her padded plot swaying back and forth in a projection of confidence.

“Isn’t she that pony with that unicorn filly that she raises by herself?” Twilight pondered upon seeing Berry Punch exit.

“You must mean Ruby Pinch,” Lyra spoke up with a bright smile. “Nice kid, really. Sometimes Bon Bon and I foalsit her when her mom’s out of town. Good thing Bon Bon’s good with foals on her own, or I wouldn’t have been able to come here to be with you girls.”

Twilight was still a little bit concerned. “You think Berry’s told Ruby about this place?”

Pacific just twirled her pacifier on its string. “If she has it’s nothing that concerns me. You mustn't worry though, we have a strict age policy. We are still a club after all, no minors allowed under any circumstances. Those are the rules.”

Twinkleshine then spoke up in reassurance. “I don’t think any foal would know how to find this place unless somepony specifically told them. This club seems really underground in more ways than one.”

“Hey! Enough chit chat!” Minuette clapped her hooves together while prancing about! “I am itching to see everything this club has to offer! I don’t know about the rest of you girls, but I just have to see who this ‘DJ Pamps’ they keep talking about is! Doesn’t sound like anypony I know.”

Moondancer smiled and nodded in agreement. “I wholeheartedly agree. Let’s get out there and shake our groove things, or however you’re supposed to say it. Sorry,” She sheepishly and shamefully admitted. “Still kind of new to the whole ‘clubbing’ thing.” Yet she still took the lead in leading her friends back out to the club interior.

“If there’s anything you need, don’t hesitate to tell our bartender or our DJ,” Pacific encouraged to the six padded ponies. “And don’t be surprised if you happen to see me out on the dance floor or even hanging by the bar. I make it a habit to oversee daily operations myself, that way I know everypony who comes here can leave feeling satisfied.”

Moondancer and Minuette strolled and swanked about in their padded flanks with the greatest of ease as they led the rest of their friends to the dance floor. That would be the easiest way to get a look at the DJ currently on duty, or at least that’s what they thought. The cake and the celebration could wait.

Moondancer especially wanted her friends to meet the DJ to whom she owed her positive outlook on this new side of her. And she had a feeling that some of them might even recognize who it was. Just another little secret she’d been holding onto.

“Oh, how do you girls make it look so easy?” Lemon Hearts grumbled as she struggled to her hooves after falling down on her padded plot yet again. “It’s like every time I take a step, my hooves betray me.”

“It’s your own fault for getting something so poofy,” Twinkleshine teased. “At least I went for something simple.”

Minuette, however, offered up some support. “It’s okay, you’ll get used to it eventually. Just take it one step at a time. Besides, if you fall down you’re not likely to hurt yourself with everything being so soft.”

“Thank goodness for small miracles.” Lemon Hearts replied while trying to keep her face from flushing red.

At last, the group as a whole reached the dance floor. And just in time too, because a new song was starting up and it seemed like everypony was getting into the groove. They bounced, shook and swayed all about without regard to rhythm. Some were even openly flaunting their padded flanks or letting their pacifiers swing freely from strings tied to their necks. Yet from the way the sound system had been set up, the music wasn’t actually as loud as one might have expected it to be for an underground club.

Amidst the cacophony of crinkles and the parade of padded plots, Twilight seemed to just make out the outlines of the club DJ. Although she couldn’t put her hoof on it, the young alicorn princess was certain she’d seen this particular pony before somewhere. The white coat almost blended in with the plain white diaper the mare was wearing, which looked super thick for some reason.

Lyra strolled over towards Twilight as she asked. “What’s the matter, Twilight? Something on your mind?”

“Tell me, Lyra,” Twilight spoke up in response while squinting her eyes. “Am I seeing things, or does that DJ look familiar? Haven’t we seen her around town somewhere?”

Lyra looked in the general direction that Twilight was looking, and slowly but surely she began to see some details that stood out to the unicorn with a mint green coat. The DJing pony was a unicorn as well, and her eyes were hidden behind an unmistakable pair of black shades with purple lenses. Then there was her two toned cobalt and cyan blue mane and tail, where the mane had a buzz cut on the sides, and the tail hung in a loose style.

At the same time, Twilight and Lyra realized who this pony was and they exclaimed together! “That’s DJ Pon-3!”

“Who?” Twinkleshine questioned as she trotted over to her two seemingly starstruck friends.

Twilight was quick with the explanation. “DJ Pon-3 is the biggest DJ on the music scene. At least, that's what I've come to understand. She’s been at so many big social events over the years: Shining Armor and Cadence’s wedding, the castle warming party after my victory over Tirek, Cranky and Matilda’s wedding, she’s even booked for my coronation when I take the throne.”

“I can’t believe it!” Lyra exclaimed in disbelief. “All this time I’ve seen her in town, bobbing her head to the beat in her headphones, and I never knew she was DJing for a club like this. I always assumed she’d care too much about her reputation to be caught dead in an underground club of any sort.”

Moondancer smiled as she happily trotted over to her friends. “Ah, I see you met her. That’s right, DJ Pamps and DJ Pon-3 are one and the same. Believe me, I was just as shocked as you were the first time I laid eyes on her. But she saved my life on my first night at the club, and thanks to her and her musician friend, I felt confident enough to embrace my inner foal.”

“Wow!” Minuette exclaimed as she and Lemon joined the others in the center of the dance floor. “She sounds like quite the pony.”

“Yup,” Moondancer nodded and then got an idea in her head. “In fact, why don’t I introduce you all to her properly?”

“I thought she wasn’t one for talking. I’ve never heard her talk once.” Twilight replied with confusion.

The glasses wearing unicorn only smiled even more while not so subtly pushing her friends towards the DJ's stand. “Well then, you’re in for a real treat, girls. Are we sure I’m still the birthday girl? Because it feels like I'm the one doing the surprising tonight.” And she giggled with foalish delight at that thought.

Eventually, all six mares were brought close enough to the stand for DJ Pamps (a.k.a DJ Pon-3) to see and hear them. And as they approached, the DJ’s expression clearly changed from one of stoicness to a pronounced smile. She waddled close (though not before flicking her horn to put a record of a nice, long song onto the turntable so as to give her plenty of cover) until she was almost leaning over the bars. It was then that she cleared her throat and began to speak. “Heya, Moondancer. So good to see ya again.”

“Hi, DJ Pamps,” Moondancer tried not to giggle too much as she said that phrase. “Just brought a couple of my friends by to say hello. It’s my birthday, and we’re celebrating it here.”

“Is that so?” DJ Pamps asked and received a confirming nod in reply. “Well happy birthday, Moondancer. How’s about I get on the mic real quick and give you a shout out?”

“Sometime later, maybe,” Moondancer offered before gesturing a hoof to her friends. “These are my friends: Lyra, Lemon Hearts, Twinkleshine, Minuette, and of course Twilight.”

DJ Pamps let out an audible gasp upon seeing the alicorn before her! “No way! The Princess Twilight?! We have royalty in the club tonight?! Why didn’t anypony tell me? I would’ve gotten something a tad more suitable for royalty than just this plain white diaper. I at least would’ve swallowed my pride and got a nice onesie for the occasion.”

Twilight sheepishly grinned. “Really, DJ Pon-3, it’s not that big a deal. I’m just a pony like anypony else, even if I am a princess.”

“Just call me DJ Pamps, that’s who I am around here,” The DJing unicorn replied with a swish of her tail. “Honestly, it’s better if DJ Pamps and DJ Pon-3 are kept separate. DJ Pamps brings in the money with her gigs here, so DJ Pon-3 can stay silent and stick to all the places you expect to see her. I’m mostly just here for Moondancer’s sake. If there’s one thing you gotta know about me, it’s that I never want to disappoint a fan no matter who they might be.”

“Moondancer says you saved her life, is that true?” Lyra Heartstrings questioned.

DJ Pamps slowly nodded. “Yeah, it’s true. No need to go into details. A DJ’s gotta do what a DJ’s gotta do. What kind of a pony would I be if I didn’t look out for the ponies who come to see me? Besides, it’s no big deal. It’s not the first time I’ve saved a life at one of my gigs, and I doubt it’ll be the last. There’s always gonna be those who go a little too hard when they party,” She then blushed as she sheepishly admitted. “Hay, even I’ve had a few ‘accidents’ here and there.”

“It still means a lot to me that you would do that, even when you weren’t sure you would stay,” Moondancer replied as she leaned close and gave the padded DJ a hug. “Really, I can’t thank you enough for what you did. Without your help and reassurance, I don’t think I would’ve come back here. And I certainly wouldn’t have worked up the courage to invite my friends here.”

“Yeah? Well just make sure mum’s the word about me playing here,” DJ Pamps insisted. “The fewer ponies that have to know about this, the better. I may not mind playing here, but I still do have a reputation to keep up. No need to let the tabloids have a field day. I'd never live it down! Bad enough I've got a roommate who teases me for this.”

Lyra just gave a knowing wink. “Hey, your secret’s safe with us. Especially with me. I know a thing or two about keeping secrets.”

“But I think I like you better as DJ Pamps,” Minuette said with a smile. “Just one adult foal to another.”

“Oh no, that’s not me,” DJ Pamps insisted. “I mean, the diapers aren’t bad or anything, but for now I’m just content with them as part of the dress code. Still, thanks for not freaking out or anything,” Then she cleared her throat. “Now, I’d better get back to doing my job before this song ends. I’d rather stay on Pacific’s good side. I don't know what she's like when she's angry, and I don't wanna find out.” As she trotted back to her turntable, she didn’t seem to be aware of the faint hissing sound she was making, or the fact that her diaper was starting to swell up.

Twinkleshine gulped as she turned to Moondancer and nervously asked. “I suppose now would be a bad time to ask if there are any bathrooms in this place? Even just one or two for emergencies?”

Moondancer shook her head from side to side. “Nope, there aren’t any. The changing stations aren’t just for decoration, you know. But honestly, with how many ponies that are frequenting this club, toilets don’t sound very sanitary. With diapers, there’s no mess, no fuss, no holding it in, and no really long lines.”

“Well, I guess I’ll just hope I can keep my pampers dry for the evening.” Twinkleshine gulped anew.

“Hey, it’s not that bad. I’ve done it a few times,” Minuette reassured her worried friend. “The first time’s always the hardest. Just try not to think about it, focus on having fun.”

“Besides,” Twilight spoke up. “Using diapers and getting changed sounds like it’s all part of the experience here. You very well can’t expect foals to change themselves whenever they feel like it, that would defeat the whole purpose,” She then whispered to Twinkleshine. “If worse comes to worse, we can always try to teleport to a bathroom somewhere else. Might be a bit tricky to attempt it while also holding it in, though.”

Lemon Hearts then declared. “Guess we’ll cross that bridge if and when we come to it. For now, let’s just enjoy ourselves.”

The six big foals returned to the dance floor a moment later, and spent a good deal of time dancing about. Sometimes they danced together, sometimes they split off to pair up with other ponies, and sometimes they all danced alone in their own little section of the dance floor.

Twilight in particular attracted a lot of attention for her “unique” way of dancing. “Note to self,” She thought in her head as she tried to keep from breaking out into a blush. “Consider those dancing lessons Rarity wanted to sign you up for.” Oh well, if it helped her friends feel more relaxed and drew attention away from them, she would dance the way she knew best.

Eventually, however, everypony in the group got tired of dancing. And they also found themselves working up quite a thirst. So they took advantage of a slower song to leave the dance floor and head over to the bar. The time had come for the birthday girl to enjoy her cake and presents, as well as maybe partake in some party games. It would be just like old times, just like the birthday parties they’d had as little fillies.

One by one, Minuette, Lyra, Lemon Hearts, Twinkleshine, Twilight and last but certainly not least Moondancer all clambered over the mesh netting on the left side of the bar. And then they all made their way to the highchairs that had been reserved for them. It was now that they got to see just how well stocked the bar was. It was truly a bar of the highest caliber, but one also well suited to the theme of the club considering it had been baby bottles and sippy cups instead of the usual bar glasses. They even had formula on one of the taps, along with such options as chocolate milk and apple juice on other taps.

Berry Punch was whistling a little tune to herself while rubbing down the bar top with a rag as the group approached. “Finally ready for some drinks are we?” She asked without looking up.

Moondancer nodded her head up and down. “Yup. It’s time for the main event.”

“Sure thing, Moondancer,” Berry said with a smile as she got out a notepad. “Just let me get the drink orders taken and then I’ll bring out the cake. I’m afraid we still don’t have any specialty drinks at the moment, still working on that. It’s hard to mix beer with stuff like formula or chocolate milk, it just doesn’t wanna work out.”

“Oh that’s okay,” Minuette smiled. “Whatever’s good enough for Moondancer is good enough for me.”

“So, two beers then?” Berry asked and received a confirming nod. “Okay. And for the rest of you?”

“Just formula, thank you,” Twinkleshine insisted in a nervous and cautious tone. “Don’t want anything that’ll really overtax my system.”

“I’m good with formula too,” Lyra insisted as well. “Bon Bon would kill me if I came home drunk. I swear, it’s like she’s afraid to let me live my life. Oh well, you can't help who you live with. Bon Bon is Bon Bon and I wouldn’t want her to be anypony else.”

Lemon Hearts spoke up. “I could really go for some genuine Sweet Apple Acres cider if you have some.”

Berry nodded back. “Sure do, just got a barrel in this morning because ponies kept asking for it. Cost nearly an arm and a leg, but I reckon with the demand it’ll be easy to make it back at least ten times over,” Then she turned to Twilight. “And for the princess?”

“One beer shouldn’t hurt,” Twilight decided after a bit of hesitation. “As long as it’s not anything too strong.”

“I’m the wrong pony to ask, my tolerance is pretty high,” Berry Punch replied as she jotted down the orders. “But DJ Pamps and Pacific both seem to have no problems with just one round. It’s only when you start drinking two or more that you tend to have issues,” Quick as a flash, she produced six baby bottles and worked the nozzles on the taps to fill them up with the ordered beverage of choice for each customer. “Here you go!” She hoofed the beverages over.

Soon afterward, Berry ducked beneath the bar top so that only her padded rear was showing. After a bit of fumbling around (which caused her padding to swish and sway, creating quite a show for everypony), she produced a cake that seemed positively massive! The only thing more impressive than it were the number of candles and the way they were arranged to create the number representing Moondancer’s age.

After carefully lighting the candles and setting the cake down, Berry joined Moondancer’s friends in singing “Happy Birthday” to her.

And just as the singing was dying down, everypony’s ears picked up the faint sound of a speaker crackling to life. Soon, the energetic voice of DJ Pamps could be heard throughout the club. “What’s up, everypony?! DJ Pamps on the mic with a special shoutout to tonight’s VIP: Moondancer! She’s here celebrating her birthday with all her friends, so let’s give a big old shoutout to the lucky birthday girl! Maybe somepony will finally be ready enough for her big filly pants!”

A chorus of cheers, applause and whistles rang out like clockwork throughout the entirety of The Fountain of Youth. The attention was enough to make Moondancer blush with a ferocity she had never known! It really did make her feel little, not since her third birthday party had she felt almost embarrassed by the attention she was receiving (and that had been the party where her parents had practically forced her to demonstrate her “big girl” status to all her peers).

“Go on, Moondancer!” Twilight encouraged in a tone of voice that sounded not unlike a little filly. “Make a wish and blow out the candles. Everypony’s waiting, and we’re not getting any younger you know.”

The glasses wearing unicorn took a deep breath and closed her eyes, thinking hard about the wish she wanted to make even if it would remain a secret. At last she opened her eyes back up, let out that deep breath, and extinguished the candles in the blink of an eye as her friends all clapped and cheered.

“Alright! Now who wants cake?!” Minuette encouraged as she used her magic to carefully cut the cake into several enormous slices.

“Aha aha aha, Minuette!” Lyra playfully scolded. “You know the birthday girl always gets the first slice.”

Moondancer nodded her head in agreement as she used her magic to grab the biggest slice of cake she could see. And then, with no thought to table manners or anything similar, she began to greedily devour the slice without a care in the world. She didn’t even seem bothered by the fact that she was getting flakes of frosting all over her cheeks.

The birthday party was in full swing by the time the cake devouring had ended (with everypony in the group having consumed at least two whole slices, and Moondancer certain she had polished off two more all by herself). All six mares had already consumed their drinks and gotten refills (in Twilight’s case she insisted on having her bottle be refilled with formula instead of beer, not wanting to test her limits).

Moondancer only just thought to wipe her face off with a rag before leaning back in her high chair, letting her rear slowly sink into her padding. Seconds later, she let out a hearty belch that seemed to echo for miles around.

“Good one, Moondancer!” Lemon Hearts encouraged with a snicker. “Oh, this was such a good idea! Best birthday party ever!”

“Well you know it’s not done yet,” Twinkleshine spoke up. “Now there’s the matter of presents. After all, what’s a birthday without presents? A really bad birthday if you ask me.”

And before long, Moondancer found herself facing down a series of five delicately wrapped presents in varying colors of wrapping paper and bows. “Oh girls, you shouldn’t have!” She exclaimed with tears in her eyes. “Really!”

Twilight smiled as she looked at her padded friend. “Hey, just because you got to do the surprising doesn’t mean we had to abandon our plans to surprise you. It’s too bad we didn’t know about this place, because maybe we could’ve gotten a gift certificate or something.”

“Enough chit chat!” Minuette encouraged! “Come on, Moondancer! Open your presents! I’m sure you’re just dying to know what’s inside ‘em!”

Moondancer grinned. “You know I am!” Then she began to rip open the wrapping paper on her first present, the one from Lyra Heartstrings (she specifically wanted to save Minuette’s present for last, seeing as she had a good feeling about what it was).

All of the presents were soon opened, and each one was an absolute delight to the big foal celebrating her birthday: Lyra had gotten her a lovely baby blue sleeper that was just the right size for her, even if the diaper would be a tight squeeze. Twinkleshine gave Moondancer some new bedsheets to replace her old, admittedly worn out ones. Lemon Hearts’s gift was a free pass to the Canterlot Archives that was valid for at least two months. And Twilight had seen fit to give Moondancer a scroll that explained in detail how to perform Hayscartes’ Method.

But just as the padded, glasses wearing unicorn had been expecting, it was Minuette’s present that absolutely stole the show! It was an entire package of Silly Filly adult brand custom deluxe diapers, just like the one Minuette herself was currently sporting (and absolutely rocking if Moondancer was being honest). “I had a few lying around from my modeling sessions,” She explained. “They always have more, so they don’t mind if I take one home every now and then. Trust me, these are the highest quality brands you can find on the market.”

Moondancer leaned over in her high chair to hug Minuette tightly! “Oh Minuette, it’s perfect! Thank you! Thank you all! You girls are the best friends a pony could ask for!”

“Hey, what are friends for?” Lyra chipperly replied. “Honestly, we should be thanking you, Moondancer. This puts anything we could’ve come up with for your birthday party to shame. We should do this again sometime. Maybe make it a girl’s night out or something.”

“Maybe once in a blue moon or something,” The glasses wearing unicorn agreed. “If we did it all the time it wouldn’t be special.”

“Well, the night isn’t finished yet,” Berry Punch spoke up as she interrupted the conversation. “We’re not closing up shop for at least another hour or so, and DJ Pamps always stays until everypony’s gone home. So why not enjoy a few more dances, and maybe come back here for a few more drinks?”

Twilight and the unicorns all got out of their high chairs very slowly, feeling very full from the cake they’d eaten and various drinks they had consumed. “Guess we can stay until close. Right girls?” Everypony nodded in agreement.

However, Moondancer had barely taken five steps when she felt an ominous gurgling in her stomach and put a hoof up to it. She froze and stood still.

“What’s wrong, Moondancer?” Twinkleshine asked with concern. “You feeling okay?”

Minuette seemed to realize what the trouble was in an instant. “You have to go, don’t you?” She asked her fellow padded unicorn, and received a rather shameful nod in response. “Let me guess, you’ve never done that in your diapers before.”

“Uh… I think we’ll just leave you two alone for a while. You know, so as to respect your privacy.” Twilight quickly spoke up as she seemed to realize where the conversation was headed, and directed Twinkleshine, Lemon and Lyra away.

Now alone with just Minuette by the bar, Moondancer struggled even as the pressure was building up in her rear. She knew there were no toilets in the club, and she doubted she could’ve made it to one in time even if there were. But the simple solution to her aching gut was something that greatly troubled her. “Have you ever… you know?” She asked Minuette while looking her fellow unicorn deep in the eyes.

The unicorn mare with an aqua blue coat slowly nodded. “Never on camera, I’m not one of those kinds of models. But every now and then I’ve done it, mostly by accident but sometimes just to see what it’s like. The first time’s always the hardest,” And she offered. “If it makes you feel better, I could do it too. I don’t really have to go as badly as you do.”

“You’d do that for me?” Moondancer hesitantly asked, ashamed that one of her friends would intentionally do anything in their diapers just to make her feel less uncomfortable about doing the same.

“Whatever helps you to relax and let it out,” Minuette encouraged as she grabbed one of her friend’s hooves. “We’ll do it on the count of three, okay? Just shut your eyes, take some deep breaths, and push. Ready?”

The glasses wearing unicorn trembled, squeezing her friend’s hoof tightly for comfort almost like a little filly holding onto her mother’s hoof. “As ready as I’ll ever be, I guess.”

The two unicorns closed their eyes, holding each other’s hooves. Minuette took the lead. “Okay then. Here we go: One, two, three.” With practiced precision, she began to push.

For Moondancer, it took only a few seconds for her body to comply with the instructions she was giving it. But the few seconds it took her gut to empty itself out felt like an eternity. At last, however, the deed was done. The smell was definitely noticeable, as was the “full” feeling in the diaper. But all in all it actually didn’t feel as bad as she had been dreading. It actually felt sort of good, now the pressure was gone and her body felt much better.

“See?” Minuette spoke up, apparently not bothered in the least by the smell. “That wasn’t so bad, was it?”

“I… guess not,” Moondancer commented. “Thank you, Minuette. I really needed that.”

The unicorn with a mane and tail like toothpaste just grinned. “I’m sure you did. I’m always happy to help a fellow foal in need. Now come on, let’s enjoy the feeling while we make our way over to the changing station. Then we can rejoin our friends like it never happened.”

“Fine, but let’s not be hasty. I’m gonna need some time to adjust to the extra weight.” The cream coated unicorn replied, and intentionally took as small a step as possible. She really didn’t wanna fall down now for fear of what might happen. Besides, the smell wasn’t bothering her as much as she thought it would. Perhaps that was another enchantment on the diaper, if so it was one she was extremely grateful for.

The two stinky padded unicorns eventually made their way over to the changing station in a clumsy fashion. Fortunately, Pacific was on hoof to make the changes go smoothly and quickly. “My goodness!” She teased when she tossed the dirty diapers into the trash can. “What did you fillies eat?!”

“Honestly, I think it was the beer more than the cake,” Minuette giggled while pointing a hoof to Moondancer. “Although, maybe a certain somepony shouldn’t have been eating so much birthday cake.”

“Hey, it’s my birthday and I’ll eat and drink as much as I like!” Moondancer giggled back. “Besides, I was nowhere near as stinky as you were.”

Pacific Glow simply ignored the playful back and forth and got both mares wiped clean, and then strapped them up into new diapers that were nice and fresh. “Glad to see you’re having a good time. That’s just what I like to see from everypony who comes here.”

By the time the two unicorns joined back up with their friends, a rather embarrassed looking Twilight was not so subtly waddling away toward the changing stations. It was possible to see a rather big (alicorn sized, you might say) damp patch had spread across her diaper. “I guess a certain princess piddled her pampers.” Moondancer teased with a wink.

“To think, she always boasted about being the most mature and responsible among us,” Twinkleshine giggled and grinned. “Guess she’s not as big a filly as she liked to think she is. Or maybe she secretly was a bedwetter all along and never told us.”

Nopony said a word when Twilight rejoined the group a short time later in a freshly powdered diaper. “Sorry, everypony,” She apologized. “At least I can say with confidence that all the diapers here are extremely absorbent, which is a good thing.”

Moondancer then took notice of what Twilight was wearing. It didn’t look like the diaper she’d worn before, it looked similar to the one Moondancer currently had on herself. “Hey, is that the Super Royal Deluxe Padding?” She questioned.

A ragging blush broke out across Twilight’s cheeks. “I guess Pacific wasn’t really paying attention when she changed me. Either that, or the diaper brand I originally had was a prototype. Guess now there’s two VIP foals in the club.”

“How do they feel?” Minuette asked. “I almost feel like changing into one myself.”

The young alicorn admitted. “Like Flurry Heart’s diapers, actually. I mean, not exactly the same since Flurry’s diapers are nowhere near as big and thick as these, but surprisingly similar all the same.”

“How would you know that?” Lyra questioned with an arched eyebrow. “I thought Minuette and Moondancer were the only adult foals among us.”

Twilight was quick to explain. “I’m not an adult foal. Flurry Heart is my niece and I foalsit her from time to time. Like any good aunt, sometimes that means having to change her diapers. And the first time I did it, I kind of underestimated Flurry’s magical abilities and overestimated my own skills. Changing her wasn’t as easy as it was changing Spike when he needed diapers, I ended up getting one of Flurry’s diapers stuck on my rump by accident. And she decided to make it so that they’d fit me.”

Twinkleshine giggled. “You should’ve asked somepony for help. That’s one of the most common mistakes any inexperienced foalsitter can make.”

“Yeah, I learned that lesson the hard way,” Twilight commented. “At least now I know how Pinkie Pie probably ended up with a diaper on her head and another on her butt all those years ago. Although, in my defense, Flurry is a bit bigger than your average foal.”

“Must be an alicorn thing,” Lyra couldn’t help but tease. “You certainly got a lot taller when you became the Princess of Friendship, Twilight. Although size doesn’t always equate to age, considering what a certain potty pants princess did.”

Twilight blushed. “I’m not a potty pants! It was only one accident.”

Minuette just smiled. “It’s okay, Twilight. Even I have accidents sometimes. You can’t help it when nature calls and there’s no toilet.”

The rest of the night passed quickly after that, especially for Moondancer who couldn’t remember a time when she had felt more carefree and comfortable than she was feeling right now. This birthday party at The Fountain of Youth had been a complete success, it had even given her a chance to see a new side of her friends much like they had seen a new side of her. And with all the presents she had received, she would most certainly remember this night and this party for years to come.
