Author's Note

Tiber Septim II, when he (or she) voted for Octavia, specifically suggested the idea of Octavia and Twilight playing, listening to, and singing music. So when Octavia (and Vinyl Scratch) won the first round of voting for this fic, I decided to go with that idea for this chapter.

Octavia's punishment is a reference to another padded pony work, Indiscreet Shipping, as well as to its much more NSFW sequel The Best Week Ever. I highly recommend the former, it's one of the all time best padded pony works in my opinion. I also threw in some references to Deviant Art user bobthedalek, who's done lots of fan art involve Octavia and Vinyl, as well as his own O.C. parents for Octavia.

Now, since Twilight Velvet, Spitfire, and Moondancer were all voted on in the first round, I'm going to count each of them as having received half a vote here. That way, if other characters that have not been deemed ineligable are voted on that weren't voted on in the previous round show up, they'll be favored. But you can vote for those three characters mentioned above if you want. And as always, be sure to suggest any ideas for what you might like to see Twilight do with her next playmate/playmates. Like last time, voting lasts a month from when this chapter is uploaded.

Octy and Vinyl (Octavia and Vinyl Scratch/DJ-PON-3)

Twilight had thoroughly enjoyed playtime with Shining Armor, it had really made her feel young again. Well, younger than she normally felt going through all of this with Princess Celestia. She was a little sad her big brother couldn't stay and play longer, but he had his grown-up responsibilities to tend to.

Fortunately, the padded alicorn wouldn't have to wait long for her next playmate to show up. The very next day, she was awoken from her slumber by the sound of a crash. It wasn't a particularly loud or violent crash, but it still startled her due to being so unexpected!

An unfamiliar, posh sounding voice suddenly spoke up. "Sorry, I didn't expect my cello to be so heavy. In my defense, I was not expecting to be called here so soon. I thought I wasn't scheduled to perform for at least another day."

And a far more laid back voice chimed in. "Really, Octy, you didn't have to bring it here. Foals shouldn't be handling such heavy things. You could've gotten a boo-boo."

Twilight spun around, suddenly finding herself face to face with a brownish-gray coated earth pony with a blackish-brown mane and tail, and a lilly white coated unicorn with a cobalt and electric blue mane and tail. Their cutie marks were music related, both depicting musical notes and symbols. And (much to the alicorn's relief) both of them were already wearing diapers. Pretty thick diapers from the looks of it.

A slight blush formed on the earth pony's face despite the fact that she was not the only pony in the room wearing diapers. "Oh... Princess Twilight!" She exclaimed as her eyes widened. "My apologies, I thought I was being called to the castle for a private performance for Princess Luna. Her birthday is coming up, after all."

"Guess it's a good thing I decided to tag along today, huh, Octy?" The unicorn said with a smile as she swished her padded rump around. "Something tells me that we're not here to give a performance."

"Indeed you are not," Princess Celestia declared as she came trotting up on the scene with a motherly smile. She looked to Twilight and happily told her in that motherly tone. "I hope you don't mind, Twily. I was thinking about who to invite for your next playdate, and I just happened to remember a certain..." She coughed into a hoof. "Incident in Ponyville not too long ago."

Twilight's wings went wide with shock! "Really?! What happened?!"

The unicorn chuckled. "All you need to know is that Octy here," She gestured to the earth pony. "Gave a certain no good jerkface what he deserved. Obviously, his mommy never taught him manners. I just wish I could've been there in pony to see Octy put that guy in his place."

Princess Celestia coughed into a hoof as she cleared throat. "Yes, well, after... that," She explained. "I still reluctantly had to punish Octavia Melody here," It was possible to see the earth pony mare blush anew. "She was to perform for my sister's birthday party, and as punishment she was to wear a diaper until after said party. Since she was already here in Canterlot, I thought it wouldn't hurt to invite her here to be your playmate for today."

"And don't forget me!" The unicorn eagerly chimed in with a toothy smile. "You probably know me as DJ-PON-3, but today I'm just Vinyl Scratch, or Vinyl for short. I'm Octy's roommate and best friend. If it weren't for me, Octy would've probably never gotten in diapers: Wearing 'em and using 'em."

Octavia looked down at her padding. "Well, I must admit they are cheaper and far less troubling than other methods of stress relief. And not having to worry about needing the washroom is helpful, I suppose."

Celestia then chimed in. "I'm glad to hear that, seeing as the bathroom will be off limits without adult supervision. I very well can't risk any mishaps or other accidents. But it's okay, I don't mind changing anypony. I'm more than used to it with Twily."

Twilight then happily threw her hooves around her fellow alicorn, hugging her tightly. "Oh thank you, Mommy! I get two playmates on the same day! I'm so lucky to have you!"

Princess Celestia just smiled, stroking Twilight with a hoof not unlike the way a mother would with their child. "I'm the lucky one, Twily. You are the cutest, most amazing foal I've ever known. I'm proud to be your mommy for as long as you need me."

"Ooh!" Twilight suddenly got an idea as her eyes lit up! "I have to tell Smarty Pants about this! Boy will she be surprised!" She promptly raced over to her bed, and retrieved the well worn stuffed donkey. "Hey Smarty Pants, guess what? Mommy's brought two new playmates here today. And they're both into music."

Octavia and Vinyl were more than a bit surprised at first to hear Smarty Pants actually talk (even if it was more or less just through Twilight throwing her voice). "Oh, that's cool. That means we can do all sorts of fun things with music: Listen to it, play it, even sing along to it. Did you know I used to sing to Twily all the time when she was on the potty? Without my singing, she couldn't even tinkle."

"Smarty Pants!" Twilight playfully whined. "Don't tell them that, they don't need to know. Besides, I don't really use the potty anymore. I like my diapers better."

Vinyl Scratch just chuckled. "Hey, it's okay. Octy sings in the shower all the time, so singing in the bathroom isn't a weird thing at all if you ask me," Then, poking her padding, she added. "And I agree with you, Twily, diapers are so much better than potties. Once I started wearing diapers at my gigs so I didn't have to worry about bathroom breaks, I never looked back. Trust me, the public bathrooms at some of the clubs I've gone to have been really bad."

"So, how long have you and Smarty Pants been like this, if I may ask?" Octavia questioned in uncertainty. "Obviously, I don't have as much experience in all of this stuff compared to you and Vinyl. I only attended my first playdate about a day or so before that... event in Ponyville that got me in trouble."

Twilight smiled as the padded alicorn proclaimed! "Oh, I've been doing this with Mommy for quite a long time now. I don't know exactly, I've lost count. But every day I've been doing it has been the best day ever! I can't wait to have another day of fun with you both: Octy and Vinyl."

Smarty Pants then saw fit to ask. "So, what was that noise Twily and I heard earlier? I know it startled us. I'm honestly surprised Twily didn't pee-pee herself in fright."

Octavia broke out into a raging blush as she gestured to a well worn case lying on the floor behind her. "That's my cello. I brought it here because I thought I was going to be performing for Princess Luna. Although now, I suppose I could get in a little bit of practice with you and Vinyl. My cello is a bit big, but I actually learned how to play it when I was an actual foal. My mum made me take lessons when I was just two years old. Potty training came along a little later."

"Meh, potty training's overrated," Vinyl shrugged. "But I'm glad I brought along some of my old tapes. They've got all the songs I loved to listen to as a foal. Figured they might help Octy find some inspiration, or just help her get into the mood."

"Can we listen to them?" The padded alicorn princess inquired in a hopeful tone of voice.

"Well, how about we have breakfast first, then you three can do whatever you want," Princess Celestia proposed to the three padded ponies in her presence. "I got so much work done at my day court yesterday that I don't actually have to go back if I don't want to."

Octavia seemed to nod in approval. "Breakfast does sound good. I didn't exactly have a chance to get something to eat this morning since I was in such a rush."

"I'll say!" Vinyl chuckled and snickered as the off-duty DJ pointed out. "You were in such a rush you didn't even notice when you'd piddled your pampers. Good thing you had me to change you. Wouldn't have wanted the entire castle staff to know about our little secret." She delivered the last line with a knowing wink.

"You were wet too, Vinyl." Octavia protested, but to no avail.

Princess Celestia led her charges to the castle's main dining room, which was thankfully void of other ponies at the current moment. "Get comfortable, my little ponies," She cheerfully told them. "There should still be some breakfast leftover from this morning. And if not, I'll happily make it for you myself."

Twilight sat at one end of the large table, giggling as her diaper crinkled and compressed as she wiggled about in her seat. Smarty Pants was seated right next to her. "Whoa! This chair is super soft!" She exclaimed to the stuffed donkey.

"Everything feels soft to me, Twily, remember?" Smarty Pants reminded the alicorn.

"I know. I wish you could feel things like this. This is probably softer than anything you're used to," Twilight commented with a dreamy sigh, occasionally using her hoof to poke at her padding. "How about you two?" She asked the two padded musicians.

Vinyl was leaning back in her chair at the other end of the table, allowing her rear to sink into the seat of her diaper. "I wish it was a high-chair, that would really make the experience feel authentic."

"Do they even make high-chairs for big foals such as us?" Octavia pondered as she sat next to Vinyl, still looking a bit uncertain. "Are we sure we should be doing this? That we're not intruding on what the princesses have going on between them?"

The padded unicorn reached out a hoof as she leaned over, reassuring her friend. "Hey, don't be nervous. Twily obviously doesn't mind, and neither does Princess Celestia. Just relax, Octy. Think of this as a much needed vacation. We can use this time to take a break from all those big pony responsibilities that keep us up at night."

The earth pony mare reluctantly agreed. "If you say so."

Just then, the dining room doors swung open. In trotted Princess Celestia, pulling a large cart behind her with her magic. She was also levitating over some bibs, tying one each around the necks of Twilight, Octavia, and Vinyl Scratch. "Wouldn't want anypony making a mess of themselves." Then she floated over three large bowls that had steam rising from them.

"Is that what I think it is?" Twilight asked as she eyed her bowl with excitement.

The sun princess happily nodded. "Yes indeed, it's oatmeal. And it has honey, cinnamon, and fresh strawberries. Just the thing for growing foals to get their nutrition," She proceeded to float over three red colored plastic spoons. "Now, can you feed yourselves, or do you want Mommy to feed you?"

Immediately, the padded alicorn threw up her hooves. "Feed me, Mommy! Please!" She adopted the best pair of pleading puppy dog eyes imaginable.

Celestia couldn't say no to such an adorable face. She trotted over to Twilight's position and sat down next to her, ready to begin the spoon feeding. As she did so, she could see Vinyl Scratch already tossing her spoon aside and using her hooves to eat the oatmeal. Octavia, after some noticeable hesitation, did the same.

Twilight, for her part, happily cooperated with her fellow alicorn on spoon-feeding. She opened up her mouth as wide as possible, allowing the sun princess to deposit spoonful after spoonful of yummy oatmeal onto Twilight's tongue. The honey, cinnamon, and fresh strawberries all created a delicious blending of flavor! Oatmeal had never tasted so good!

Sooner than either princess would've liked, however, the spoon-feeding came to an end as the bowl was depleted completely of its contents. Still, it had been fun while it lasted.

"Now, how about some milk to wash it all down?" Princess Celestia proposed to her fellow alicorn.

Twilight knew what her fellow alicorn meant, but it was a bit hesitant. "Are you sure we should do that in front of Octy and Vinyl?"

The sun princess looked across to the other two padded ponies, who seemed fully occupied licking the last bits of flakey oatmeal from their hooves. "I don't think they're paying any attention to us. We'll have to make this quick, though." And she exposed her teets.

Twilight, with practiced precision, latched onto one of Celestia's teats and began to suckle. It wasn't long before the taste rich, creamy milk was on her tongue. She closed her eyes, listening to the rhymtic sound of Celestia's heartbeat as she timed her suckling to it.

"Okay, Twily," Princess Celestia said after almost a whole minute had gone by. She gently weaned the padded alicorn off the teat as she said in that motherly tone of hers. "That's quite enough milk for you for now. We don't want to upset your tummy."

The padded alicorn, though disappointed that the breast feeding had been so brief, reluctantly agreed. "Okay, Mommy. But your milk was really, really good! It tasted like cake!"

Celestia chuckled. "Oh, it did, did it? How odd. I didn't know my milk could have that kind of taste to it. Perhaps it's the lactating pills I've been taking to help me produce milk more easily."

"Mommy take medicine?" Twilight questioned with concern.

"Just for breastfeeding," The sun princess reassured her charge. "It's what mommies do for their little ones sometimes," Then she turned her attention back to Octavia and Vinyl. "Now, if you'll excuse me, I have a few messy fillies I need to clean up. Just sit right there until I get back, Twily." And she then rose from her seat at the table in order to go wipe off the faces of the two padded musicians.

After breakfast was over, Celestia led her padded charges back to the guest bedroom Twilight was staying in. She made sure to lock the door securely behind her so that nopony could barge in unexpectedly. Then she encouraged the trio. "Go ahead, go play your music. I'll be right here if you need anything."

Vinyl smiled, allowing her violet eyes to grow big as she took hold of both Twilight and Octavia by the hoof. "Come on, I've got so many tapes I wanna show you!" Soon, she had brought them before a brightly colored box. Opening the locks with her magic, she revealed a wide variety of colored cassette tapes. There was also a bright red tape player/recorder, and a pair of matching headphones.

"I can't believe you actually held onto those old tapes, Vinyl," Octavia commented in an odd mix of surprise and light mockery. "Tapes like those haven't been used in ages. These days, it's usually records, though CDs are also popular."

The off duty DJ's smile just grew bigger and brighter. "Well, these tapes were all the rage when I was a foal. I remember my parents used to play them for me all the time: When I was being put for naps or going to bed, when I was being too much of a hooful and needed to calm down, or even when we went on really long carriage rides together," Lighting up her horn, she soon settled on a bright yellow colored tape. "And guess what? This old tape player still works. Sometimes, I'll pop in a tune or two to get me in the mood." She promptly popped the tape into the player and pressed the play button.

The player clicked and came to life. Soon, music could be heard emerging from the speakers near the bottom of the device:

Row, row, row your boat,

Gently down the stream.

Merrily, merrily, merrily,

Life is but a dream.

"Think that's cool?" Vinyl said with a grin. "Check this out!" She used her magic to press the fast forward button on the player, then stopped it on a whim. A different tune started to play:

Ninety nine buckets of oats on the wall,

Ninety nine buckets of oats.

Take one down, pass it around,

Ninety eight buckets of oats on the wall.

Ninety eight buckets of oats on the wall,

Ninety eight buckets of oats.

Another press of the fast forward keep, followed by another sudden stop brought yet another tune on:

The wheels on the cart go round and round,

Round and round, round and round.

The wheels on the cart go ground and round,

All through the town.

"Vinyl, these are basic foal songs!" Octavia seemed to blush ever so faintly. "Don't you have anything less... kiddie?"

"I told you, these tapes were really popular when I was a little filly," Vinyl replied as she shrugged off the comment. "This is actually one of the special tapes my parents made for me," She proceeded to use her magic to stop the tape, pull it out of the player, and present it to both Octavia and Twilight. "See?" Scribbled in barely legible black letters were the words "Vinyl's Special Tape #1: Vinyl's Favorite Songs"

Twilight grinned. "My first mommy didn't really do songs for Shining and I when we were little, but she did have stories she used to tell us. They were always so wonderful: Stories about things like a rainbow of darkness, and witches, and ponies going on adventures to distant lands," A lone tear came into her eyes as she recalled. "I should've asked her to write them down somewhere so I'd always have them. I can't remember the last time I heard them, but it has to be have been years."

Octavia reached out a hoof to calm her fellow padded mare down. "Hey, it's alright. I'm sure your mother still recalls them to some extent and would be happy to write them down for you if you asked," She then commented. "My mother actually kept a lot of the things I had when I was a foal. Apparently, the doctors told her that after she had me, she couldn't have another foal again. That would explain why she's been almost over eager to see me have foals of my own."

Vinyl giggled. "Your mom's pretty weird, Octy. But hey, moms are like that. My mother and father made the tapes for me because they were always busy with their work, my big brother had to care for me. He was the one who got me into music in the first place. He was a DJ too, and he still performs for special occasions sometimes."

Smarty Pants, meanwhile, was rummaging through the collection of tapes the off duty DJ had brought with her. "Wow!" She commented as she carefully set various colored tapes aside. "Seems like your parents made a lot of these tapes, Vinyl! There's a tape of your favorite sounds, a tape of your favorite lullabies, even a tape of some potty training songs. I wonder if any of them are like the ones I used to sing to Twily."

Now it was Vinyl's turn to look embarrassed. "How did that get in there?!" She exclaimed in shock as she hastily snatched up a bright white colored that had the words "Potty Time" written on it. "Ugh, that's the one tape I didn't wanna bring with me!"

Octavia donned a goofy grin. "Now I'm quite curious as to what sort of songs your parents could've had recorded for you on a tape like that. I don't recall songs being a part of my potty training experience."

Vinyl quickly sought to change the subject. "Well, there's plenty of other tapes to listen to. I've got taped recordings of some of the biggest musical acts from when I was growing up. Some of these songs haven't been re-released in years!"

But Twilight got an idea! "How about, instead of just listening to tapes, we make our own tape for my mommy?"

"You mean, for Princess Celestia?" Octavia questioned, and got a confirming nod in return. "Sort of like a private concert? We make a tape of us performing a song?"

"Why not? You still have your cello with you, right?" Vinyl pointed out, gesturing to the case the aforementioned instrument currently resided in.

"But we don't have any other instruments," The earth pony mare protested. "We can't have a concert with only one instrument."

Smarty Pants then giggled. "We have all the instruments we need right here."

Octavia blinked in confusion. "What are you talking about? I don't see any instruments besides my cello."

Twilight chuckled as she waddled over to Octavia. "Duh, the instruments exist in our imagination. We can play any instruments we want. We don't even need to practice," Then she giddly proclaimed! "Ooh! I have an even better idea! Instead of taping our concert, we do it live for Mommy! She'll love it!"

Vinyl began to beam from ear to ear. "Hay yeah! Now you're talking, filly! The only thing better than taping your own music, is playing your own music yourself!" Then she put a hoof to her chin, deep in thought. "But what song should we do? It's got to be something that'll sound good with Octy's cello. Too bad foals don't know how to use turntables, because if I had my turntable I could mix up some really sick beats for us."

Octavia, meanwhile, had trotted over and opened up her cello case. With a fair bit of effort and clumsy waddling, she was able to drag the heavy instrument over to where Twilight, Vinyl, and Smarty Pants were all seated. She managed to catch the tail end of their conversation. "You know, all this talk about foals and foalish things has actually gotten me thinking. I do seem to remember this one incident at a certain gala a few years back."

At that the padded alicorn's face became flush with shame, it was even possible to hear a faint hissing sound as she peed a little bit from the sudden embarrassment. "That was Pinkie Pie, not me!"

"I know, and I'm not mad," The cello playing earth pony reassured the padded alicorn princess. "It did liven things up a bit. I believe that song was called 'The Pony Pokey' if I'm not mistaken."

"Oh, 'The Pony Pokey'," The unicorn mare commented in amazement. "I'm impressed you remember a song like that, Octy. As a matter of fact, I helped bring that song back into the mainstream with a rocking club remix. And your gala incident was just the inspiration I needed," She smiled, looking at Octavia. "What would we ever do without each other, Octy? Feels like we were meant to be. Heck, now we can even say we've been together since we were in diapers."

Octavia waved a hoof, playing off the compliment. "Oh Vinyl, it's nothing, really. I'm flattered you could find inspiration even from something I found rather embarrassing at the time," Then she happened to notice the off duty DJ's flanks, and a noticeable detail about the diaper currently wrapped around. "Speaking of diapers, did you know you just wet yourself, Vinyl?"

The off duty DJing unicorn looked down, noticing a faint yellow tint to her previously pristine white diaper. "Guess that just goes to show how much I've gotten used to wearing and using my pampers. Didn't even realize I'd opened my floodgates," She then sat down, causing her diaper to squish. "Wow! I must've soaked it more than I thought!" She looked across to Octavia. "Well, what are you waiting for? You know we're not allowed to use the potty. Aren't you gonna feel weird being the only one not getting changed?"

"Come on! It's easy!" Twilight declared as she patted her soggy diaper. "Just let it all out!"

"It's okay, Twily was just as nervous about it the first time she decided to do it," Smarty Pants reassured the earth pony. "I promise, we won't look." She covered her button eyes with a hoof and turned her head. Twilight and Vinyl promptly turned their heads too so as to give their friend the privacy they felt she needed.

Octavia sighed deeply. She didn't have much experience using her diaper, and unlike last time she didn't have the luxury of being distracted by a playtime fantasy. She shut her eyes, trying to remember the trick she'd read once about imagining a waterfall (despite not having the sound of running water that had been recommended). She spread her legs out almost involuntarily, hoping that if she relaxed her posture her body would be less likely to fight against her. It took a long time as the cello playing earth pony stood there in silence, why was she so pee shy all of a sudden?

Finally, however, the proverbial dam burst. Octavia's bladder finally emptied itself in a steady stream, the hissing became rather audible as a result. Her diaper subsequently swelled up as it absorbed the pee as best it could, soaking it all up like a sponge. Slowly but surely, the stream died down until it was a faint trickle. And then it stopped for good. She sighed in relief, taking in the feeling of a wet diaper. Sheepishly, she declared. "I'm... I'm done, I think."

Vinyl was the first to take notice of her friend's deed. She grinned and winked. "See? That wasn't so bad, was it?"

"N-no, it... wasn't." Octavia seemed to reluctantly agree.

Twilight smiled. "Now we can all get changed, and then we can start practicing for our concert for Mommy. She'll love it!"

A trio of diaper changes soon followed, and then the three freshly padded ponies went back to preparing for the concert they had agreed to put on.

Of course, Princess Celestia had overheard everything and knew about the concert. But she feigned ignorance all the same. "Twily wants it to be a surprise, so I'll be surprised. It's just like the other stuff we've been doing together as mommy and child." She thought to herself with a smile on her face.

Eventually, Twilight, Octavia, and Vinyl Scratch (and of course Smarty Pants even though she couldn't really play any instruments) believed they had practiced enough. They had no stage, but that didn't matter, much like the instruments they would create the stage with their imagination.

Twilight waddled over to Princess Celestia with an exceptionally bright smile, trying to hold back her excitement so as to not give away the surprise. "Hi, Mommy." She chipperly greeted.

"Hello, Twily," Celestia replied in that motherly tone of hers. "Are you enjoying your playdate with Octy and Vinyl?"

The padded alicorn princess nodded and then proudly said. "Yup. And we decided to do something extra special. We're gonna do a little concert for you."

"Oh? For me?" The sun princess commented as she again feigned ignorance. Sure, it might be fairly obvious given her lack of acting experience, but it was the thought that counted.

"Uh-huh!" Smarty Pants chimed in. "We're going to do a song called The Pony Pokey. And you can join in too if you want. You don't have to sing, just do what Twily and I do while we play our instruments."

Octavia then cleared her throat, cello at the ready. "And now, Princess Celestia, we are pleased to bring you..." She paused for dramatic effect, then declared. "The Pony Pokey!" And she, Vinyl, and Twilight (and Smarty Pants too) all started singing in unison. As they sang, they performed various gestures in time to the music, which went like this:

You reach your right hoof in,

You reach your right hoof out.

You reach your right hoof in,

And you shake it all about!

You do the Pony Pokey, meeting lots of folks with clout.

That's what I'm talking about.

You step your left hoof in,

You pull it right back out.

You step your left hoof in.

But you better help him out!

You do the Pony Pokey but should find a different route.

That's what it's all about.

You kick your back left in,

You pull your back left out.

You reach your back left in,

Just be brave and have no doubt!

You do the Pony Pokey, feeling like you're gonna pout.

That's what I'm singing about.

You tilt your head in,

You tilt your head out.

You tilt your head in.

Then you shake it all about!

You do the Pony Pokey even though your date's a lout,

You're better off without.

You stomp your whole self in,

You stomp your whole self out.

You stomp your whole self in,

And you stomp yourself about!

You do the Pony Pokey and you give a little shout,

That's what I'm talking about!

You do the Pony Pokey,

You do the Pony Pokey,

You do the Pony Pokey,

And that's what it's all about!

About midway through the song, Princess Celestia couldn't help but notice Twilight adopting a most unusual expression upon her face. She was about to ask what it was, before she saw her fellow alicorn spread her legs apart and lift her tail. Celestia's trained ears could hear the sound of muffled grunts even over the sound of the music.

In a matter of seconds, Twilight gave one big push and her diaper noticeably bulged in the back. A faint scent of methane began to waft through the air. Yet the alicorn went right back to singing and dancing as if nothing had happened, and nopony else seemed to notice yet what Twilight had just done.

When the song ended, Twilight still didn't seem to be aware of the fact that she had messed herself. She instead smiled as she looked upon Princess Celestia, seeing the sun princess clap her hooves in approval. "Oh bravo! Bravo!"

"Did you like it, Mommy?" The padded alicorn asked in a hopeful tone of voice.

Celestia happily nodded in confirmation. "I loved it, Twily! You and your playmates were wonderful!" She wiped a lone tear from her eyes. "You continue to make me so proud of you!"

The young alicorn princess beamed with pride. "Thank you, Mommy!"

Celestia then cleared her throat. "Well, now that your concert is over, Twily, there's something we need to discuss."

"What do you mean, Mommy? Is something wrong?" Twilight asked with concern, still apparently unaware of her dirty diaper or the stench coming from it.

The sun princess was perplexed by Twilight seemingly not knowing about having messed herself. "Does she really not know she made a poopy? Or is she just pretending like that other time?" She thought to herself, remembering her conversation with Luna a while back. But she quickly pushed those thoughts and concerns to the back of her mind as she did her best not to adopt a goofy grin, all the while she said to her former student. "Yes, something is most certainly wrong, Twily. You have a messy diaper. And it really stinks!"

"What?! Why didn't anypony tell me sooner?!" Twilight blinked in apparent disbelief as she looked to her diaper and saw a very obvious bulge spread across the back.

"I was actually just about to say something myself, but I was so caught up in my performance that I forgot," Octavia admitted in a somewhat shameful tone. "As for Vinyl. Well, I guess she's gotten used to such smells after all the late night gigs at clubs. I've never been to any myself, but they do have a certain reputation."

Vinyl just replied. "When you gotta go you gotta go."

Smarty Pants then teased. "Goodness, Twily! You sure are a stinky baby. You should hurry up and get changed before you make the whole castle smell bad!"

Celestia then levitated Twilight into the air and carried her away. "You're definitely in need of a change, Twily. And probably a bath too."

The rest of the day was a blur of fun for Twilight, who enjoyed her two musically talented playmates and playing with them just as much as she'd enjoyed all her prior playmates. The day of fun tuckered her out, and she slept soundly that night under Celestia's watchful eye.

Octavia and Vinyl Scratch both agreed to keep Twilight's secret to themselves, and they too slept soundly that night. They woke up the next morning in the private suite in the castle that had initially been reserved solely for Octavia as part of her "punishment", both feeling refreshed.

Vinyl was just packing up her tapes and getting ready to catch the train back to Ponyville, when she happened to notice something taped to the door of the suite. "What's this?" She wondered aloud as she took it off the door with her magic. It was a letter, and she read it aloud:

Dear Octavia Melody and Vinyl Scratch,

Thank you ever so much for agreeing to be Twily's playmates, and for agreeing not to tell others about her secret. It makes me happy to know that Twily can be herself around ponies like you without fear of being judged or made fun of.

I do hope you will consider coming back for another playdate some time, Twily really enjoyed spending time with you two. And the little concert you helped her stage for me was most appreciated. It was adorable.

As I promised before, you will be greatly rewarded for your services. I hope you'll both appreciate it. And Vinyl, don't worry about Octavia, I assure you that word of her private performance for my sister's birthday and what it means will not be leaked out.

Sincerely,

Princess Celestia
