First piece of My Little Pony fanfiction I've done.

--

“Where the hay is that speaker?” Vinyl Scratch stomped through the apartment, gritting her teeth as she searched. Normally laid back, the DJ was at the tail end of the three hour search for one of her speakers. An hour and a half of that time had been spent in her own room, of course, and the usual mess was somewhat more...messy as a result.

Now at last she had gone through every other part of the apartment and that left her with one, final option. A place she rarely went and when she did never alone. A place of evil and boring, mind-crushing Classical music.

Octavia’s room.

She cautiously pushed the door open. Her friend and flatmate was still at least an hour away so there was no reason for Vinyl to keep looking over her shoulder as though the earth mare would materialize and start scolding her in that prissy way she had. Stepping into the room she looked around it. All boring and fancy, like Octavia was making her room as prissy as herself. Not that Vinyl minded, really. She rather liked that a prissy pony like Octavia was friends with her and really quite down to earth when you got to know her. Her head was full of silly things like ‘decency’ and ‘common sense’ Vinyl had no time for.

The speaker didn’t seem to be there anywhere she looked but Vinyl Scratch was nothing if not determined. She looked under Octavia’s perfectly made bed and crossed the room, almost amazed by the fact she didn’t have to dance over any number of discarded items like in her own room. It was alien to her.

Grumbling Vinyl went to the last place left; Octavia’s closet. Why her friend got a walk in closet in her room and she didn’t was a mystery Vinyl couldn’t be bothered solving. Besides, how much  space did you need for bow ties? Looking in there were a number of fancier outfits she knew Octavia needed occasionally, some she didn’t but kept because her family kept sending them to her and a locked chest at the back, nearly hidden.

‘Wait, locked chest?’ Vinyl trotted in and brushed the draping dresses off the chest. It had a huge padlock holding it shut, the chest itself was made from tough looking oak and was nearly as big as Vinyl. ‘Now isn’t that interesting...’

Vinyl didn’t often stick her nose into things that didn’t concern her, despite what Octavia might say and give a number of examples to support. She was also very much about respecting another’s privacy, even if Octavia said she wasn’t and could bring up five incidents in the last week where she showed a complete lack of said respect. But now she was curious.

Leaving the chest for the moment Vinyl ran back to her room and spent twenty minutes searching for a bag a friend of hers in high school asked her to look after five minutes before the guards came by to arrest him. She had kept it because hay, why not? He had shown her how to use some of the little tools in it and she made had use of those skills for many purposes. Mostly breaking into Octavia’s stash of expensive, high quality cookies.

While looking for it she found her speaker, under her bed.

‘Too bad I never thanked Open Lock for his lessons.’ Vinyl thought as she lifted the lockpicks out with her magic and set to work.

After half an hour the padlock popped open and dropped. With a grin Vinyl pushed the lip open. She couldn’t wait to find out. If she had just ignored this it would have bugged her for weeks. Her grin died as she looked at the revealed contents. Lifting some she inspected them with a confused expression. She had been expecting any number of things, like a stash of stolen gold bricks, a Vinyl Scratch shrine, sex toys, anything but not this. Actually, she had been hoping for a shrine to herself. She had NOT been expecting this.

Looking at the chest, an idea popped up inside her confused thoughts. 'So, Octy's into this stuff huh?'

<-->

Octavia sighed in relief as she entered her home, setting down her instrument’s large case. Her usual rehearsal with her ensemble had been rather tiring recently and she was happy to be home. Time to relax and renew herself. It was just a pity Vinyl was home at the moment or she could have indulged..

‘No, no I mustn’t think like that. I like spending time with Vinyl, she’s my best friend.’ Octavia scolded herself. Still, she enjoyed it when she had the apartment to herself.

Stepping into the living room she gave Vinyl a tired nod. The unicorn was laid out on the couch, her trademark glasses pushed up onto her forehead. She grinned at the earth mare.

“Hey there Octy, how was practice?” She asked casually.

Too casually, thought Octavia. She narrowed her eyes suspiciously. “Rehearsal, Vinyl, as I have told you a hundred times before. It went well, although I must admit there were a few stressful moments.” She pressed a hoof against the back of her neck and rolled her head. “Oh, I really do need to relax.”

“Yeah, relax.” Vinyl grinned at her. “You do need to relax, don’t ya? Lots of different ways to relax, aren’t there? I like to listen to some mixes, maybe veg on the couch.”

“Let’s not forget to add bothering me to that list.” Octavia said with a roll of her eyes. Something was off with this conversation.

The DJ nodded. “What do you do to relax Octy?” She asked, something about her grin cheeky.

Octavia pursed her lips as she stared at her friend. “You already know my hobbies Vinyl, we live together. Why do you ask?”

Shrugging Vinyl got up and circled the couch until she was on the other. “Oh, just curious. After all we’ve been friends for ages but sometimes I feel like there’s some big, secrety-secret you’re keeping.” Her legs and half her body were hidden by the back of the couch but she put her hoof on something. Something wooden.

Octavia tilted her head to the side as she considered her friend’s strange words. She did have a secret, a very big one she had long kept hidden. Was it obvious she was keeping a secret though? She had been cautious and careful, indulging only when she knew Vinyl was in another city or too far away to arrive unexpectedly. The topic was still making her slightly worried.

“A secret? Nonsense Vinyl, what sort of secret do you think I might have that I would keep it from my best friend for so long?” She asked, keeping her voice clear, confident and as firm as possible. Her unicorn friend would pounce on any sign of weakness.

“Dunno.” Vinyl shrugged. “A little secret like, say,” Her magic lifted the long chest up and dumped its contents on the couch, “this one?”

Silence filled the room as Octavia stared at the pile of thick cloth diapers and just as thick, crinkling disposables, her cutie mark emblazoned on the front of many cloth diapers and others decorated with childish patterns. Plastic pants littered the piles, some frilly and foalish, others plain and some covered in yet more child’s designs. A few folded up items opened as they fell to reveal oversized onsies.

Vinyl grinned at her over the couch. “Spot on, right?” Her grin shrunk as she watched Octavia. The earth mare shook as she stared at the pile.

Her secret had finally been discovered. Vinyl knew she was a freak, knew her humiliating little secret. She was going to kick Octavia out for being weird. Years of worrying about her secret and fear of being revealed burst free as tears slid down her cheeks. With a sob she galloped from the room, running to her room and slamming the door shut.

“Octy, no, wait!” Vinyl jumped over the couch too late and her friend’s door slammed shut before she could stop it with her magic. “Damn it, open up!”

“No!” The shriek came back. “Y-you know I’m a f-freak! I’m w-weird and you p-probably hate me!”

She could hear the sobs in Octavia’s voice and Vinyl found a dagger of guilt jabbing her in the heart. She hadn’t meant to do that! Octavia was meant to blush and stammer responses, not run away crying.

Looking at the door, Vinyl grit her teeth. She had seen a lot in various clubs and while it was odd, she had nothing against Octavia being an Adult Foal. But the earth pony could be stubborn. Vinyl was going to have to show her friend exactly how fine she was with it.

Her horn lit up and things began to float over.

<-->

Octavia buried her head in her pillow, crying into it. Her life was over. Nopony was supposed to know about her secret. She would be a laughing stock if it ever got out. She knew she should have stopped but she could never bring herself to get rid of it. The longest she had been able to resist the temptation had been a month and in the end she had spent an entire day in diapers, suckling on her favorite pacifier.

So busy recriminating herself Octavia didn’t hear the metallic clinks of Vinyl’s work on her lock or the sound of her door opening quietly. Her ears flat and covered by one of her pillows the first sign that she wasn’t alone anymore was the tug of magic pulled her away from the top of her bed and flipping her onto her back.

“Yo, Octy.” Vinyl Scratch greeted her. “Before you say anything, sorry about that. I just wanted to see you blush, not make you cry. That would be totally uncool.”

Blinking in confusion Octavia opened her mouth to say something. Before she could get a word out something familiar filled her mouth. The largest of her pacifiers squeezed into her mouth and she began to work it without thinking.

Vinyl grinned at the bobbing pacifier. “Just so you know, I’m fine with this. I mean damn, I never would have guessed you were into all this Adult Foal stuff. Legs up Octy.” She instructed before using her own magic to lift Octavia’s legs up before she could move. A thick diaper floated up and settled under her. Octavia let out a muffled gasp of surprise as she felt the soft material and seconds later powder being applied. “This is just me showing you that I don’t care. You’re still the same prissy, boringly sensible, awesome Octavia you’ve always been.”

The diaper fastened around Octavia’s hindquarters and was pinned in place. Still in shock Octavia just lay there for the moment, feeling the blissful warmth and comfort of a diaper. Eventually Vinyl stepped closer, looming over the bed and giving her friend an uncertain look.

“Uh, you okay Octy?” For a second she looked slightly nervous. “I just wanted to, ya’know, show you that I’m fine with it. I did a gig in a place where a few ponies into this stuff came pretty often, so not like the first time.”

Slowly Octavia lifted her head and with one hoof removed her pacifier. “I...Vinyl...” She croaked, not sure what to say. Her best friend, the friend she lived with and often had slightly worrying dreams of, had just diapered her and was saying she didn’t care. She didn’t care that Octavia liked to dress like a foal. She didn’t care she liked to wear diapers and suck on a pacifier. She was still her friend.

Eyes burning with tears again Octavia all but leaped at her friend, catching the unicorn in a bone crushing hug.

“Thankyouthankyouthankyouthank!” She hugged the white mare to her and buried her head against the DJ’s shoulder, overcome by emotions in an uncharacteristic fit.

A hoof wrapped around her shoulders, rubbing her back. “Hey, it’s no problem. Come on Octy, don’t cry.” Vinyl, her voice surprisingly gentle, urged her friend.

She gasped for breath so she could reply, slowing her babbling down. “Nopony has ever found out, its always been such a secret. Oh I was so worried and I thought you were going to kick me out for being a freak-”

“Whoa whoa whoa. Whoa.” Vinyl pulled back slightly so she could look Octavia in the eye. “Octy, babe, you aren’t a freak. Well, you’re a neat-freak and kinda a control freak sometimes but you’re not a freak for this. Stop saying that.”

“B-but I am.” Sniffed the musician, looking down slightly.

Vinyl’s mouth pressed into a flat line. She hated to see her friend thinking of herself like this. “No, you aren’t. If you say that again Octy I’m gonna be real annoyed because I hate lying. It’s kinda odd, yeah, but you’re not a freak. If anypony says you are I’ll buck ‘em to the moon, you got me? Right to the moon! They’ll land so hard they’ll make a crater!” She said firmly.

The amount of times Octavia had told her friend violence was a bad way to solve a problem was beyond count. But this once she just hugged her friend again. “V-Vinyl...”

They stayed like that for a while, just holding each other close. Eventually Octavia pulled back, drying her eyes. She collected herself, drawing on her long practice of being dignified as Vinyl did something stupid.

“This really means a lot to me Vinyl.” She said at last, sitting back on her diapered rear. It landed with a loud ‘bomfph’ and she actually giggled before blushing and looking at Vinyl uncertainly. To her surprise the DJ was grinning widely.

“Wow.” Vinyl Scratch said, her eyes bright. “You just giggled. Damn Octy, you should have told me. You put those ponies I saw at the club to shame in terms of cuteness.”

Her blush growing Octavia looked down. Vinyl made a habit of flirting with her and while she could ignore it normally right now it was making her flustered. “Um, t-thanks?” She took a deep breath. “Vinyl, we need to make sure things are clear. I do not want this to change anything between-”

Her pacifier was shoved back in her mouth. “Hold on a sec Octy.” Vinyl said with a snicker, enjoying the look of annoyance Octavia was giving her. It looked so cute with the pacifier. “There’s something wrong with this picture, let me fix it.” She had what could only be called a wicked grin.

Octavia’s unheard question about what she meant was answered when she felt her bowtie unsnapping from her neck. She stared at it and looked back at Vinyl as it floated away, slightly confused.

“What? You ever seen a foal with a bowtie?” Vinyl rubbed her chin. “Actually now I think about it I wouldn’t be surprised if you were born with one. Popped right out with a little bowtie, looking at the hospital room with a frown for being so messy.” She snorted with laughter, the glare her prissy friend shot her making her laugh even harder.

Taking her pacifier out Octavia tried to regain the seriousness of the conversation. “Very funny. Now, I assure you I will still keep this out of the way and to myself-” She began.

“Oh no no no!” Waving her hooves Vinyl cut her off. She looped a hoof around Octavia’s neck. “Keep it out of the way, are you kidding? Please, I saw how much stuff you had in that chest and that’s when you were trying to keep it secret. I’m betting you indulged when I was out on gigs, right? Knowing you, you probably didn’t even risk it unless I was out of town, am I right?”

Octavia’s blush was all she needed to know she was right.

Vinyl grinned. “Well that’s not happening anymore. I scream music whenever I want despite the fact it annoys you all the way to Tartarus and back. You like your diapers, which is totally fine with me, and you think I’d be annoyed if you did it more?” She smacked her friend on the shoulder. “No can do babe.”

What Vinyl meant took a few seconds for Octavia to absorb. Was...was Vinyl telling her she could do this...whenever she wanted? Her heart beat excitedly but she forced it to be calm. There was no way she could do that, there was no way Vinyl could really mean that.

“What? Vinyl, you cannot be serious!” She exclaimed, drawing back. “You don’t even know how far I go with it. For all you know I soil them too and that would be unacceptable.”

Scratch gave her a look. “Do you crap in ‘em?” She asked simply.

“No! Well...I mean, no! That would be gross.” Octavia snapped with a blush.

Grin growing slightly, Vinyl leaned in. “I’m getting the feeling you’re still hiding something...let me guess, you DO use ‘em though?”

Opening her mouth to deny it Octavia snapped her jaw shut as she looked her friend in the eyes. “Y-yes.” She finally admitted. “Just the disposables and just...just wetting.  I know it’s horrible and gross and undignified but....”

Vinyl rolled her eyes. “Babe, you really should get over that whole ‘dignity’ thing. It’s boring. Ever use the cloth ones?” She asked suddenly, patting the one Octavia was wearing.

“N-not really. I was too worried about having to clean them and risking you finding them.” The musician replied nervously.

“Right, gotcha. What else is there? Do you act like a foal? Got a pacifier already and I found a few more little toys in that chest. Let’s see, a bib, some bottles, more pacifiers, you even had a rattle in there.” Dragging Octavia out, Vinyl pulled her towards the living room. The pacifier floated out in Vinyl’s magic behind them.

The earth pony nodded slowly, her blush still in full force. “Sometimes. Not always. It-it was just relaxing. I feel...safe.” She explained. “I used to do solo rehearsal here with a diaper on and my pacifier when you used to do a lot more work further away.”

“Wow, I was missing out.” Vinyl teased as they arrived.

Seeing the chest, something occurred to Octavia. She gave Vinyl a narrow, much more usual look. “Vinyl...how did you find the chest anyway? It was in the back of my closet...locked.” She added darkly.

Vinyl grinned nervously as she levitated the collection back into the chest. “...I tripped over it?”

“...sometimes I hate you.” Octavia sighed, as she finished packing. “I do wish you would just pretend you never found out.” She complained.

“Oh?” Vinyl’s eyebrows rose and she gave Octavia a skeptical look. “Do you really? You’d rather you were still guilty doing this in private and being worried whenever you did that I would find out and think you were a ‘freak’?” She snorted. “Yeah, no, not buying.”

Put that way the gray mare couldn’t really deny that maybe this was better. She knew she was going to be subjected to a lot of good natured teasing but...but maybe this wouldn’t end badly. Vinyl had basically told her to wear her diapers whenever she wanted.

“You’re right.” She conceded. The look of surprise Vinyl wore was worth it. Clearly she hadn’t thought Octavia would agree so quickly. “I’m glad you found out, I think. Just knowing you don’t mind is...reassuring. But I do think we need to establish some ground rules.”

She wore the look of surprise this time when the DJ nodded. “I agree completely. But you don’t get to make them all. For every rule you get to impose, I get to make one. How’s that sound?”

“Why do you get to make rules?” Octavia asked indignantly.

“Because if it weren’t for me you wouldn’t get to be wearing that snug little diaper of yours at all and we both pay the rent.” Answered Vinyl with a grin. “You can make the first rule.”

Rolling her eyes but realizing there was no other way to go, Octavia went ahead with it. “Rule one; no telling anypony else, not under any circumstances.”

Vinyl shook her head and she almost looked offended. “Really Octy? You really think I’d tell your secret? Well, your rule to waste. Rule two; whenever you wearing a diaper you have to use it. For pissing at least.”

“What?” Her cheeks red Octavia shook her head. “No, we’re not making that a rule. Just because I lik- I do not mind....peeing in these does not mean I always do.”

Lifting the chest in her magic Vinyl just laughed. “Too late babe, it’s the rule. Feel free to make your next one.”

Grumbling Octavia decided she would just ignore the more crass ‘rules’ Vinyl imagined she could come up with. “Rule three; you will never take any form of picture or recording of me in any of my, uh, foal wear.”

“Rule four; when you use your diaper and I’m home, I get to change you. I also get to do any diapering you need.” Vinyl said, her grin growing even wider as Octavia processed the rule.

Her cheeks redder than ever she shook her head with greater force then before. “W-what, Vinyl, y-you can’t be-”

“I am.” Scratch overrode her. “It might surprise you but I foalsat when I was younger and come on, how awesomely did I do your diaper before? Make your rule.”

Hesitating and wanting to argue Octavia’s protests died. She had always wanted to have another pony change her, a secret little fantasy she had been certain she would never realize. A lump in her throat she just nodded.

“O-okay.” She agreed quietly, looking down. “Um...rule five...I...I can wear...” she hesitated but pressed on, “I can wear my diaper even if you change your mind about it being alright.”

“Wow, it’s like you’re making redundant rule on purpose.” Vinyl rolled her eyes. “Rule six; Vinyl gets to make the rest of the rules because Octavia keeps making up stupid, pointless rules.”

Octavia’s hesitation vanished. “What? You can’t-” Her pacifier was jammed back into her mouth and her words were lost as the unicorn’s magic left it adhered to her lips. “Mmph!”

“What was that? No objections?” Vinyl turned an ear towards Octavia as she tried and failed to the pacifier out. “Great! Rule seven; whenever you’re wearing a diaper I get to put your pacifier in whenever I want. Rule eight; you have to wear your bib for every meal when you’re wearing a diaper.”

The silenced earth pony continued to try to protest while Vinyl went on. Eventually an idea occurred to the unicorn and she vanished, returning with a whiteboard and marker. Bringing her friend back to the couch she set to work writing down all the rules. Octavia finally gave up. Vinyl had already realized quite well that the chance to indulge in her secret hobby meant Octavia was willing to put up with a lot.

The result of their one-sided ‘discussion’ was written out on the board:

Octy’s Foal Rules (or ‘whenever Octy is wearing a diaper’)

1: Octy must use her diapers for peepee.

2: If Octy has to go poopy, she has to ask Vinyl to let her use the potty.

3: Vinyl won’t take any pictures of Octy in her diapers (unless she’s looking super cute)

4: Octy isn’t allowed to change her own diaper, unless Vinyl is more than an hour away from home.

5:  Vinyl is allowed to put Octy’s pacifier in whenever she wants.

6: Octy isn’t allowed to remove her pacifier without permission.

7: Octy has to wear her bib for all meals.

8: Vinyl gets to make up any more rules she wants.

9: Disobeying any rule means Vinyl gets to punish Octy however she wants.

Looking proudly at her list of rules, Vinyl sent Octavia a cocky smirk. “So, how’s that sound?”

Octavia facehoofed. Maybe Vinyl finding out hadn’t been such a good idea.

<-->

“Welcome back!”

Octavia had taken one step into the apartment on her return from today’s rehearsal and there was Vinyl Scratch, DJ extraordinaire and frighteningly happy about the fact Octavia was an Adult Foal.

“...thank you.” Octavia trotted in, looking around suspiciously. “How has your day been Vinyl?” She asked politely instead of demanding to know what was being planned. It had been a week since Vinyl had found out and life had continued something like normal. She had shyly worn a diaper a time or two but mostly she had kept it under wraps. She had also avoided the need to use her diapers.

“Great, great...hey, Octy, wanna make a bet?” The unicorn asked completely out of the blue.

Octavia gave her another suspicious look. This was highly unusual but she had learned a time or two that Vinyl made bets either a) when the odds were completely in her favor or b) she thought it would be funny either way.

“A bet on what?” Octavia asked worriedly. Vinyl followed her as she went to her room and put her instrument case down.

“Oh, nothing. I’ve noticed you only wear your diapers for a short time if at all. How about this; I bet you can’t go an entire evening, from now to your usual bedtime at ten without using your diaper.” Vinyl challenged.

Octavia gave her another look. She had used the bathroom before leaving to come home so she knew it wouldn’t be a problem. But she had to wonder why.

“Even if I did agree, what would you get out of this?” She asked with narrow eyes.

Vinyl’s grin showed she was not at all bothered. “If you do you use it, you have to wear diapers when you’re home from now on. Unless there’s company, obviously.”

Octavia frowned. “Why in Equestria would you want me to do that?”

“Duh.” Vinyl rolled her eyes. “Because you want it, you’re just too embarrassed. And...I have to admit, you look pretty damn cute with that big padded behind of yours.” She grinned nervously. “So, whaddya say?”

“What do I get if I win?” No reason to give Vinyl wriggle room when she inevitably lost.

The unicorn shrugged. “Let’s go with a classic; I’ll be your slave for a week. Sound good?”

It took Octavia seconds to decide. “You, Vinyl Scratch, are on.”

Both mares smirked, certain they were about to win. Only one of them could be right.

Chapter 2

Octavia trotted into her room, Vinyl at her tail. The musician rolled her eyes at how eager her friend was to get started. It made her feel a little warm inside as well, although she would never say that out loud. It did make her feel a little happy that her friend was so accepting, even if it was odd that she was also getting into it so much.

“Vinyl, I can do it myself.” She said as she went to her closet. The unicorn cut her off, jumping over her and heading in first. “Vinyl...”

“Nope!” Vinyl’s magic helped her lift the chest out easily. She grinned at Octavia, who just rolled her eyes. “I get to do it! It’s in the rules, remember, and I know how much you love rules.”

Octavia just sighed although a smile tugged the edge of her mouth. She did her best to smoother it but from Vinyl’s grin she failed. “Fine, if you insist.” She said, doing her best to look and sound reluctant. Neither of them was fooled.

A diaper floated out of the chest and Octavia could tell the thickest of her cloth diapers had been chosen. At Vinyl’s urging she lay on her back and waited, blushing slightly. Her best friend was about to diaper her after all. What part of this wasn’t weird?

“Legs up!” Vinyl crowed eagerly, tapping the gray mare’s side until she did it. The diaper was slid under her rear and the bottle of foal powder floated over in Vinyl’s magic. She happily powdered the earth pony mare, giving her a thorough coating. “For when you wet your diaper.” She said confidently.

Octavia rolled her eyes, giving her a confident smirk back. “We’ll see Vinyl, we’ll s-” Her pacifier suddenly filled her mouth and she glared at Vinyl for the interruption.

Chuckling Vinyl finished the diapering as she pinned the garment tightly on. “The rules.” She sung gloatingly before looking back to the chest. “Now, which pair of plastic pants do you want? Let’s see, a boring clear pair or this pair with the frills along the top and your cutie mark?”

“Mmf mpht!” Octavia mumbled, crossing her hooves and glaring at the DJ.

“The frilly pair? Just what I was thinking.” Vinyl said with a laugh, levitating the pair up Octavia’s legs and stretching it over her diaper, ignoring her friend’s adorable pout. She patted it, the plastic cover crinkling loudly. “How’s that?”

A blush came to Octavia’s face at the pat. It was...nice. Vinyl’s surprise diapering the night she found out had been the first time anyone else put her into a diaper and since then she had been yearning to experience it again. But a proper Canterlot mare’s dignity held her back.

She reflected on the dignity a Canterlot mare should have as she sat up and pulled the pacifier out, her plastic diaper cover crinkling loudly with every movement. “Did you have to do that?” She asked dryly.

Vinyl grinned. “Yep. See, look how awesome I did it.” She stepped back, pushing up her shades to look Octavia up and down. She whistled. “You know Octy, I never thought a diaper could look so hot. On you though....”

Sighing at her friend’s words Octavia got onto her hooves and looked back. She blushed slightly at the sight of her thick diaper and its cover, feeling and seeing her back legs spreading slightly at the thickness. She had gotten these ones specifically because they were big enough to make her waddle slightly.  Walking a few steps she nearly smiled at the waddle she was forced into.

She only realised Vinyl was still watching her when the DJ let out ‘d’aww’. Octavia blushed brightly, still embarrassed about doing this in front of her friend.

“N-now remember Vinyl, just because I’m wearing a diaper is no reason to act differently than nor-” Octavia began.

“Don’t treat you differently blah blah blah, what’s the point then?” Vinyl interrupted. She began to pull the earth mare out to the living room. “No hiding in your room. You’re spending the evening having fun with me.”

“Oh joy,” was Octavia’s dry response as she waddled out. “Will we start with the mind-numbing techno loud enough to break ear drums or is that just going to turn on at random and make the neighbours hate us some more?”

Vinyl rolled her eyes. “Oh ha ha, Octy, you’re the wittiest foal I’ve ever met.” She grinned at the blush that got from her friend. “You’re a lot more fun like this you know.”

“No, I do not know.” Octavia grumbled. She took a seat on the couch, trying not to smile at the sound of the crinkle. It was undignified. It was still hard not to smile. She loved her diapers, and the plastic pants and her onsies and pacifier and all of it! She had spent most of her teenage years embarrassed and ashamed, thinking there was something wrong with herself. Octavia winced, remembering the time she had been worried it was a sign that she had some far darker fetish but that fear had soon faded.

She suddenly realised a white hoof was being waved in front of her face and she jerked back in surprise with a yelp.

Vinyl was giving her a slightly concerned look. “You okay there Octy? Ya kinda zoned out for a minute.”

“I-I’m fine.” Octavia took a deep breath to calm herself. She had long made peace with her unusual desires and there was no point digging into the past.

“You didn’t look it.” Vinyl’s voice was low as she looked at the gray mare uncertainly and Octavia cursed her friend’s awareness. Vinyl wasn’t stupid and if she didn’t notice things it was because she was focused on something else. With just the two of them here and nothing else happening her full attention was on Octavia.

“I am fine, Vinyl, please.” Keeping her voice steady she looked down at her diaper, poking the cover. The crinkle brought a small smile back to her face and without thinking Octavia let out a giggle. She blushed, aware of how odd this was compared to her normally reserved behaviour. But when she looked up Vinyl was....smiling?

“You have a nice laugh, Octy, you don’t use it enough.” The DJ said happily. Her horn glowed as she finished levitating a few things out and Octavia finally saw on the carpet in front of the couch a blanket now adorned with a number of the toys taken from her chest. “I’m gonna whip up something for dinner, you relax. Play a little.” She suggested cheerfully before trotting out.

Left on her own the musician stared at the toys. She had played with them before, always feeling slightly self-conscious even on her own but unable to deny how much she enjoyed it. It was all so...simple. Simple and easy. She didn’t have to worry about her appearance, about doing something wrong, about anything but relaxing and enjoying herself. Like the days when she had the apartment to herself and she could just play whatever she wanted.

Octavia loved her ensemble but there was always a pressure they all felt. Classical music in Canterlot tended to be listened to largely by the elite and their preferences for musicians were strict. A single mistake could see not only her but her friends blacklisted. Only the Princess’s own quiet words into a few important ears had kept that from happening after the Gala incident.

Looking around to make sure Vinyl was gone, Octavia slowly got off the couch. She approached the square blanket and its toys cautiously, as though it might be a trap, until finally she stepped onto it and sat down in the middle. For the moment she was content just sitting there, looking at the toys around her. She could hear Vinyl in the kitchen, getting something ready to eat. Maybe she could just...try it. Vinyl wasn’t going to see. She would be fine. She just had to....reach out. Right now. Now. Just about now. She was going to reach out now. Now.

How long she spent trying to convince herself to reach to the toys, Octavia wasn’t sure. Long enough for Vinyl to poke her head out and announce that dinner would be ready in a bit and absolutely nothing melted and would need to be replaced, nothing at all. The earth pony mare just nodded and when her friend left, finally worked up the courage.

With a hesitant hoof she reached out and picked up the closest toy. The rattle made a little sound in her hoof, rough and ugly to her musician’s ear but still somehow not that bad. She giggled slightly, shaking it again. With one hoof tapping the rattle against the floor and giggling at the sound Octavia reached for another toy with her other hoof. She had enjoyed this one in private, and Vinyl was in the kitchen anyway.

Peeking around the corner that turned into the kitchen Vinyl grinned. Her friend only stopped her playing for a moment to reclaim her pacifier before starting again and the sight made the unicorn want to grin wider than her face could handle.

It was an amazing change coming over her normally reserved friend. Being ‘proper’ was always so important to Octavia that when they had first met Vinyl had wondered how she managed to go to the bathroom without feeling ‘improper’. Apparently the answer was ‘by using a diaper’. Sometimes it felt like Octavia was denying herself things, making herself miserable because if she didn’t she wouldn’t be acting the way she had been raised.

The sight of her just enjoying herself was amazing in its rarity. Vinyl wasn’t a psychologist but she guessed her personal repression and apparent enjoyment of regression could be linked. Or something. She wasn’t a psychologist. The closest she had been called was a psycho and that was by the pony currently shaking a rattle.

Vinyl Scratch grinned widely as she went to work, finishing the simple meal. Spaghetti with tomato sauce, somewhat out of a can since she didn’t have any handy homemade recipes from ‘Mama Scratch’ or anything so quaint.

She stopped for a second and thought about that. Mama Scratch...she wondered if it was weird that she wanted to get Octavia to say that. It probably was, but she never concerned herself with worrying about being weird. Normal was boring.

“Octy, dinners is served!” Deciding to be nice Vinyl gave her friend nearly two whole seconds after the announcement before looking into the living room.

Octavia was in the process of throwing the rattle far away and her ears went flat when she realised she hadn’t been quite fast enough. “U-uhm...” She looked nervously at her friend.

Vinyl just smirked. “Dinner time. You can play again after.” She didn’t try to keep the amusement out of her voice. Every time her friend blushed felt like a small victory for the DJ, although she wasn’t sure way.

Forcing her blush away Octavia followed Vinyl into the kitchen and the small table they used for eating. On it were two plates, both piled high with spaghetti. One of the plates, Octavia finally noticed, was a plastic child’s plate with small plastic utensils. She looked at Vinyl, who was fighting back giggles.

“You seem to have prepared awfully well for this, haven’t you?” She asked rhetorically, after removing her pacifier and taking her seat. “I suppose no proper utensils would be in the cards?”

“Not even in the deck.” Vinyl answered as she took her seat opposite her. “Wait, don’t start yet. Can’t forget this.” She levitated a bib over to Octavia. The earth pony mare just rolled her eyes as it was tied on. It was one of her own, with her cutie mark on it.

“I guess I should be glad you’re not trying to feed me.” She grumbled half-heartedly. Octavia was definitely glad she got to eat on her own. Not even a little bit secretly disappointed. Not at all.

Vinyl just grinned even wider. She began to eat, using her natural levitation to keep from making a mess. Octavia began to eat as well, managing to hold the small utensils in her hooves. After all, everyone knows ponies can hold things in their hooves without needing it explained or anything.

The small knife and fork made things a little harder. She used the knife to keep the amount of spaghetti she had around her fork at one time from getting too much, not that there was much room on the fork. It was a child’s, and with soft, rounded tips. Much to her displeasure Octavia found stray ends of spaghetti getting sauce on her chin. By the time she had finished her plate her chin and the sides of her mouth had a sizable amount of sauce on them. Throughout it all she felt Vinyl’s eyes on her but Octavia refused to look up.

“There, done.” Octavia announced, pushing her plate away. “Now, can you please hand me a napkin?” For whatever reason the only napkins were out of Octavia’s reach, near Vinyl.

Vinyl pretended to consider it for a few seconds before shaking her head and grinning. “I’ve got a way better idea.”

Before she could ask what it was Octavia felt her bib began to move, Vinyl’s magic lifting it up to wipe at her face. She blushed at the blatantly childish gesture until her face was clean and the bib was removed. It bounced in front her, displaying the amount of sauce she had gotten on her face.

“Not so prim and proper now, are ya?” Vinyl said. She chuckled, collecting the plates and leaving them in the sink for later.

“Because you gave me tiny utensils.” Octavia pointed out, giving her a narrow a look. “You also chose food you know is hard for anypony who isn’t a unicorn to eat cleanly.”

Shrugging off the reasonable points Vinyl just smirked. “Excuses, excuses. You can go play now, I know you were having lots of fun.”

Octavia opened her mouth to reply but was cut off by a certain feeling deep inside. It was just that little feeling telling her she was going to need the bathroom later, the weakest feeling of needing the bathroom.

‘I...I used the bathroom before I got home!’ She thought frantically. ‘I can’t have been drinking that much today.’

Something about her expression must have alerted Vinyl to what was going on. Her smirk grew.

“Hey, Octy, did you wonder why I decided to do this today, out of all days?” She asked with a smug look, one she knew Octavia hated.

The classical musician looked at her friend suspiciously, distracted from her worry. “Not particularly. But I am curious, now you ask.”

“It was pretty warm today, wasn’t it?” Vinyl asked.

Octavia blinked at the random question. “Uh, a bit. It wasn’t too bad.”

Vinyl nodded, her smirk not wavering. “But that place you practice at with your band-”

“Ensemble.”

“-whatever, that place you practice gets kind of hot, doesn’t it? Not good ventilation and all.” Vinyl went on, not disturbed by the interruption. “When it gets hot, I kind of tend to fan myself with random papers without thinking about it. Do you know what you do?”

It took Octavia a moment to follow where she was going. “I, uh, never gave it any thought.” She admitted.

“You drink a lot of water. You never think about it, you just sip away constantly.” Explained Vinyl with the same smirk. “A little bit each time. Just a little sip but you do it so often, you just drain away at your drink until you need to refill.”

Octavia was starting to get a little nervous. Vinyl was wrong. She didn’t do that....although, thinking back....

‘No! No thinking back, or you’ll realise she’s right and – oh, damn.’

Vinyl smirked at the look of realisation on her friend’s face. She wished she had a camera. “Want a drink?” She asked with a smug smirk, levitating a sippy cup over to Octavia.

The earth pony gulped as she came to understand that this was going to be a lot harder to win than she had thought. And she wanted to win.

...didn’t she?

Chapter 4

Octavia was nervous. Like, super nervous. She waddled along, feeling foalish and infantile as she was led along by the hoof by her best friend. A best friend who she suspected she was going to be calling something very different from now on. A best friend who was taking her to get her wet diaper changed. She blushed at the thought. Vinyl was going to change her wet diaper. She kept thinking that sentence over and over. She found herself liking it more with each repetition.

Looking back at her friend turned foal Vinyl couldn’t help grinning. She could tell Octy was warming up to this, if the way she had wet her diaper hadn’t been a big enough sign.

“First, here’s something I prepared earlier.” A bottle came floating out of the kitchen in Vinyl’s magic and she grinned, replacing the pacifier with the bottle and using her magic to keep it in. “A little drink before bed.”

Suckling on the milk, Octavia smiled hesitantly.

“I’m gonna change your diaper now, and then it’s bedtime. You already go to sleep around now, and foals need plenty of napping,” Vinyl told her.

Octavia nodded, nursing her the nipple of the bottle as she as led to her room. It was comforting and reassuring to her. Keeping that in her mouth helped her come to terms with the sudden change, slowly suckling down milk. She was left standing in the middle of the floor for a few seconds while Vinyl retrieved the large plastic changing mat.

The unicorn laid it out and patted it. “All right Octy, on the mat for mommy.”

The ‘mommy’ made Octavia blush again but she did as she was told.

“Good girl.” When Vinyl said that she blushed again, feeling magic undoing the bottom of her onesie and peeling it up to expose her frilly plastic pants. “Off comes the protection...”

Vinyl’s magic tugged the crinkling plastic down, leaving the sodden cloth diaper to sag. They slipped down her legs until they came off. It was obvious that Vinyl had been planning on this, or hoping at least, since she had foal wipes ready to go once she had the diaper unpinned.

“Whoa, that is one soaked diaper.” she said with a chuckle, getting a whole new blush from Octy. “But nothing mommy isn’t prepared to deal with.”

The assurance helped and Octavia smiled at her shyly. They seemed to push things a bit further, going from a dry diaper change to her actually wetting one. The chance to call somepony ‘mommy’, somepony she lo- trusted with everything.

Although she remembered a moment later that Vinyl found her out by violating her privacy. The touch of a cold wipe on her lower area surprised the distracted mare and she eeped at the chilly touch. She kicked her back legs to get the cold away.

Vinyl laughed again, light and happy. “Calm down Octy, it’s just the wipe. Won’t take long, but can’t have you getting a rash.” She snickered. “Hah, I would love to see how you explained having a diaper rash to your band. Oh, fine. you’re still a huffy little foal. Nearly done.” She said when she saw the sour pout.

A few seconds later Octavia broke her pout and giggled. “Gotcha.” she laughed, her fake pout gone.

Vinyl blinked. ‘Did Octy just make a joke? Play a trick?’ She asked herself. She began to laugh again as well when she realised yes, Octy had played a little trick on her.

“What a smart foal.” She said through her laughter, reaching down to Octavia’s stomach. She glanced at Octy’s face, wondering if she could just touch her like that. All she intended to do was rub her stomach a bit, and compared to changing a diaper it didn’t seem much.

With a happy nod from Octavia, the DJ gave her a rub and to both their surprise lowered her head to blow a raspberry on it. This prompted a chorus of giggling and squealing from the normally dignified mare. That dignity she tried to hold on to was slipping away faster and faster but she just didn’t care.

As she was sent into hysterics by the raspberry Octavia felt free, more than she had in a long time. She loved just how openly she was able to laugh. She could laugh openly most of the time, but she was always doing it in a restrained, controlled way. Control was what being sophisticated was all about. Half of her job was looking fancy and completely in control. Her instrument required more finesse and control than most ponies needed, being an earth pony. She had wondered before if part of that was why she fantasized about being looked after.

She was distracted by the wipes touching her again, wiping away the last of the urine that had dampened her coat. She blushed as she realised exactly what Vinyl could see from this position.

Vinyl grinned down at her, loving the way Octy squirmed as the old diaper was pulled away.

“And up go your legs.” Vinyl gently nudged Octy’s legs up, the earth pony mare doing most of the work with that. The soaked diaper was completely freed and, lifted by Vinyl’s magic, a new one replaced it. It was just as thick as the last.

The foal powder floated over and Vinyl began to cover Octavia thoroughly, enjoying it every time her big foal squirmed at the strange feeling of being diapered again.

“V-Vinyl...” Octavia began, stuttering slightly.

Her pacifier floated over and she took it into her mouth almost without thinking.

“That’s ‘mommy’ to you Octy,” Vinyl told her off gently. “At least when you’re being changed. Or doing something foalish. Outside, and when we’re just hangin’, you can call me Vinyl. But right now it’s mommy, ya got that?”

Octavia nodded, eyes wide. Vinyl really meant it. She really, really meant it!

“Or momma. Mama. Ma. Any of those,” Vinyl went on as she finished powdering Octavia. That done she began to do the diaper up, pinning the thick cloth on with her plastic pants wrapping it in crinkling protection. The onesie was refastened and Vinyl helped Octavia up. “Right, bedtime. I know you like to get to bed on time. Come on, up ya get.”

With Vinyl prodding her Octavia climbed into bed, blushing when Vinyl pulled the sheets back for her and began to tuck her in. It was making her feel very odd. She hadn’t been tucked by somepony in....

‘Wait, have I ever been tucked in?’ She wondered as white hooves pulled the bed sheet tight around her. Eventually she realized Vinyl was looking at her, somewhat uncertainly, so she smiled.

Vinyl smiled back. “Tucked in by mama. Bet you love that. Sleep well Octy, mama will wake you up in the morning.” Vinyl leaned forward, hesitated for a moment, then kissed Octavia gently on the forehead. The now empty bottle was replaced by one of pacifier and Octavia worked it automatically. Both mares blushed as Vinyl drew back. “Night Octy.”

Just as she flipped the light switched and stepped through the door, Vinyl stopped at Octavia’s quiet call.

“Good night...mama.”

Vinyl waited a moment, turning so the light would show her face. She gave Octavia a grin and stepped out, closing the door behind her.

Both mares let out great sighs at the same time, and both kept on smiling until they fell asleep.

Octavia was certain she would be up late into the night, warm and comfortable as she was snuggling down in her bed, her onesie tightly covering her and bed sheets tucked in around her.

She was surprised when she woke up the next morning. She could not remember falling asleep, but judging by how well she slept she must have drifted off almost immediately. Yawning, Octavia turned over, idly remembering Vinyl’s promise to wake her up. Her pacifier had stayed put throughout the night, gently suckled on by the happy mare.

Her clock, analogue of course, ticked in front of her.

‘How odd, that clock almost looks like it says ten to eleven in the morning.’ She knew that could not be right. After all, she always got up at eight in the morning, cooked herself a nutritious if somewhat boring breakfast, woke up Vinyl, had a shower, woke up Vinyl, prepared her appearance, as was befitting when going into dignified company and woken up Vinyl the final time before leaving at half past ten. There was no way she could have slept in until ten to eleven.

Octavia stared at the clock, her smile slowly dying until her mouth was flat and her pacifier went still. She blinked, trying to clear her vision. The clock remained stubbornly at ten- no, nine to eleven.

The warmth and pleasantness of her waking slowly drained away, replaced by growing horror.

This was replaced by embarrassment when the first thing she thought was;

‘Mama didn’t wake me.’

Octavia blushed, immediately telling herself to stop that. It was all well and good for Vinyl to tell her to call her that, but after a night to think things through Vinyl was doubtless going to have realized how silly an idea this was and the whole thing would be-

“Mornin’ Octy! Mama’s got breakfast all ready to go!” Vinyl barged through the door, grinning. She still looked tired, probably since she was up before midday, but she was cheerful. “Come on, up ya get.”

“Vi-” Octavia began to say, staring at the unicorn as she drew back the covers.

Boop.

The earth pony mare jerked, cutting herself off, at the gentle boop on the nose from Vinyl.

“That’s mama to you.” Vinyl grinned. “You get a few chances today Octy, but you better learn when to call me that or my wittle musician is gonna have a red plot to show off at band practice.

“Weheawsaw.” Octavia mumbled around the smaller pacifier. She blushed and took a deep breath “...Mama, I hab weheawsaw in an houw!”

Vinyl grinned at getting Octy to call her that again. “Good girl, no spankies today!” She cheered. “Don’t worry, you’ve got plenty of time. I made breakfast this morning. Try not to be too impressed.” She said modestly.

Octavia found herself...calm. She was totally, utterly, calm. She was not sure why. Letting Vinyl pull her out of bed, Octavia had started to think about how strangely reassuring it was when she called VInyl ‘mama’ when she realized something important.

She had to pee. Crossing her back legs Octavia looked at Vinyl pleading. Cheeks red, she suckld on her pacifier to build up the courage she needed to say it.

“Mama...I needa...needa go peepee.” Saying such a foalish thing was a little shocking. She had played around with saying things like that to her reflection before but never to another pony.

As happy as she was to hear that Vinyl just smirked at Octy. “So?”

“So....” Octavia stared at her in confusion for a few seconds until she finally realised what she meant. Her cheeks went red. “Vinyw! Uh, I mean, mama, wo wan’ me ta go...in my diapuh?” Octavia lisped around her pacifier, frowning - pouting - at how hard it was to talk. “Can I habe an smawwer paci?”

Vinyl levitated one of the smaller bulbed pacifiers up in front of Octavia. “Hmmmm.....” She rubbed her chin with a hoof thoughtfully. “When little Octy goes peepee in her diapees, then I’ll let you have a smaller pacifier.”

Looking at her friend it was clear she was not going to back down and Octavia was fully aware of how determined she would be to see it through. Still, even after last night it was hard for her to just go ahead with it again.

Face scrunching up, Octavia closed her eyes and just...let go. Her diaper drunk her liquid waste thirstily until it was turning yellow as she continued to let out all of the bottle from the night before.

Her diaper was wet. The classical musician’s cheeks went red and she sucked on her pacifier like she was taking calming breaths. Peering at Octy over the top of her sunglasses Vinyl realized what it was as well and grinned.

“Your diaper is wet, isn’t it? Oh, good girl Octy, good girl.” She gently led Octavia around to the plastic diaper mat laid out on the floor next to the bed and pushed her onto it. “Your changing mat is staying right there, unless we have guests.” Vinyl said, getting to work.

Octavia didn’t say anything, still blushing and meek from wetting her diaper in front of Vinyl for a second time, while her onesie was opened among the frilly-rear and her diaper unpinned. The fact Vinyl praised her for it made it even more embarrassing. Being called ‘good girl’ by Vinyl should not make her giddy with excitement.

Vinyl removed the crinkling diaper-cover, followed by the diaper, and began to clean her up, using wipes to clean away most of the urine that got on her coat. She removed the onesie next, to Octavia’s unhappiness. She let out a whine of protest, blushing and covering her mouth the moment she made the wordless, foalish sound. The DJ just laughed.

“Sorry babe, as you reminded me so angrily you have band practice to get to. Mommy’s little musician needs to keep up with practice, so you go have a shower and I’ll finish breakfast. Then I’ll show you how to get from one end of Canterlot to the other in less time than it takes you change your diaper.” Vinyl grinned, replacing Octavia’s larger pacifier with a smaller one.

The classical mare suckled on it, pouting slightly but nodding in agreement as she headed to have a shower. She slipped into the bathroom and hurried into the shower, the sound of water cascading over her soon filling the flat. Vinyl whistled as she put away the foal things and went back to the kitchen.

When Octavia emerged from the shower she could smell the pancakes, the scent filling their apartment. She would never admit it but Vinyl made delicious pancakes. She credited herself somewhat with that, since without her badgering Vinyl would never have taken that cooking course and would probably still be leaving on vacuum packaged and canned foods. When she wasn’t eating horrible greasy fast food that is.

Pacifier bobbing in her mouth Octavia trotted out to the ktichen just in time to see Vinyl lay the plate of steaming, syrup covered pancakes in the table. She glanced at the clock almost as an afterthought. Not long had passed and she knew she should be panicking. Even if Vinyl had promised to get her there on time. Especially so. Vinyl followed through on her promises, unless she forgot, but not always in a conventional way. For all Octavia knew, Vinyl was going to try to use a time machine. She’d probably break space-time, knowing her, and everypony would have two heads and fifteen hooves.

Removing her pacifier Octavia realized quite unhappily the problem. “I’ll need another shower.” She grumbled, shooting a look at Vinyl. “You should know how messy eating pancakes with all this syrup would be for an earth po...wait, you do know...”

Vinyl answered with a grin, levitating a bib up on one side and knife and fork on the other. “It’ll be faster this way.” She said, rubbing her forehooves together at how her plan had gone. The bib wrapped around Octavia’s neck before the earth pony mare could reply.

“Oh, very well.” Octavia sighed loudly, to make her annoyance clear, as the magically levitated cutlery began to slice up her pancakes. That annoyance didn’t extend to not opening her mouth widely to be feed, blushing cutely when the first slice was slipped in.

It was quite the effort of Vinyl not to openly giggle at Octy’s easy acceptance of being fed. Unfortunately she couldn’t make this go for as long as she wanted, slightly rushing through the meal. Only a bit of syrup got on Octavia or her bib, which Vinyl whisked away once they were done. She let Octavia clean herself off.

“So...Vinyl, how do you propose to get me to my rehearsal in fifteen minutes?” Octavia asked, frowning. She wanted to trust Vinyl, but, well, she was....Vinyl.

Vinyl opened the door, backing out as Octavia trotted out with her large instrument on her back. “Just me Octy, you won’t even have the words to describe how awesome it’ll be.”

}-{

Fourteen minutes later, a frazzled Octavia trotted into the room reserved for her quartet. She refused to answer what was wrong, simply vowing ‘never again, never again’.

}-{

Vinyl Scratch whistled, flipping through the magazine she had. It was a local mall’s weekly catalogue, one of the larger shopping complexes. Rather than electronics, fizzy drinks or anything she usually checked it for, she had turned to the foal section. Not for actual purchases so much as ideas.

“Finally made passionate love to your roommate and thinking about starting a family, right?”

She yelped, nearly knocking over her drink. Catching it with magic she glared at the pony who had surprised her. “First off; what are you talking about?  Second; what are you talking about?”

“You’re looking at the foal section of the catalogue. I mean, I am a bit confused about how you managed to knock her up without a wang, but I guess you’re just that good. Or did she knock you up?” The pony, responsible for the wiring at the club she worked at most frequently, laughed as he was warded off by a banishing wave of a rolled up catalogue.

Grumbling to herself Vinyl gave it another look. Yeah, there were a few good ideas in there. Now she just had to find them in a larger size. She grinned as she left the empty club, whistling a tune most ponies needed electronic assistance to make. She was pretty sure where to start looking. Octavia was pretty anal about stuff like receipts, and it wasn’t like she hadn’t invaded her privacy already. How much harm could doing it again do?

}-{

Octavia gulped, staring at the door to her own home. Their shared apartment was not, in general, a door she hesitated to open much. When there was painfully loud music she in fact usually entered it at a gallop, growling and preparing to shout at Vinyl for violating the local noise pollution ordinance.

But here she was, gulping. After a few seconds of hesitance, she sighed and used her key. She hadn’t been at her best today, understandably distracted by the events of last night and the morning. Her bandm- ensemble had asked her a few times if she was having trouble sleeping. As bad as she felt for lying to them it was that or tell them the truth. As good friends as they were she wasn’t about to tell them her best friend and roommate had changed her wet diaper.

She briefly entertained the image of the look on their faces if she did but suppressed it. She was not Vinyl, doing things on a whim and...

She stopped thinking, freezing mid-step as a grinning Vinyl appeared in front as if she had summoned her by thinking her name too loudly.

They stayed like that, staring in each other’s others for a few seconds.

“Heeeeeeeeey Octy....” Vinyl’s grin carried into her voice. Her shades were pushed up, exposing her eyes and all the eager glow in them. “Guess what I found?”

“Your common sense?” Octavia’s mouth answered for her. “Oh, silly me, its been years since you lost it.”

Vinyl was not one to be put off by snark. She laughed. “Nope! I found your receipts!”

“...” Octavia looked at her quietly. “Did you invade my privacy again?” She asked.

“A bit.” The DJ admitted with a sheepish smile. “Hey, its worked out so well the first time I didn’t think it would do any harm. And look, now I know where you got all that stuff, and we can go get more. It's saturday tomorrow.”

Sighing, Octavia carried her instrument case to her room, trying her best to ignore Vinyl’s pestering. She had made sure not to forget anything this time, and had fortunately managed to avoid running into Lyra. It was only a matter of time, but she was happy to make that time far, far into the future if she could manage it.

Vinyl trotted along behind her, practically bouncing. “You need to learn how to hide things better, I found those receipts after only like ten minutes of looking!”

“Yes, I will do my best to remember to conceal receipts of purchase in my own room, just in case anypony else decides to violate my privacy.” Octavia said icily, biting back a sigh. “Why are you so excited about my receipts anyway? I am positive purchases of new bow strings is not that interesting to you.”

They entered her room and she did her best not to look at any of the places her adult foal items were hiding, just out of sight. No need to look too eager, after all. Fortunately she very, very rarely had others over, so there was little fear of them being found.

Vinyl still caught the way Octavia’s head turned slightly, guessing what she was looking at. “Well, a receipt for the, ahem, All-Ages Nursery Store kind of suggests its where you got your favorite underwear.”

Octavia stopped what she was doing. She sighed. “Where did you find that?” She asked wearily. “I ripped up all the receipts from there, just in case they were ever found.”

“Wow, that’s kinda paranoid.”

“Its almost like my roommate lacks a sense of personal boundaries, isn’t it?”

Vinyl laughed. “No, I have a sense of them. Just not a very good one.” She said cheerfully.

“Oh of course.” Octavia grumbled. She stood there, her bowtie removed, not saying anything. Vinyl was just as silent, grinning at her.

About a minute passed in silence.

“...you’re going to make me ask, aren’t you?”

“Yep!”

Octavia sighed, feeling her odd nervousness return. It was like stage-fright, which she had gotten over a long, long time ago. She knew Vinyl was fine with it, she had made it clear she was more than just fine with it, but some frightened little corner of Octavia was afraid that if she asked, Vinyl would say no.

“Vinyl, can you....can you diaper me?” She asked, cheeks glowing red through her grey fur.

Vinyl didn’t seem to hear. She cleaned out one of her ears. “I think I almost heard something there, but it didn’t sound like my little Octy asking for her diapee.” She teased.

Her blush intensifying, Octavia understood what Vinyl wanted. “M-Mama...” She squeaked “C-can I have m-my diapee?”

White hooves pulled her into a hug. “Sure thing! All you had to do was ask.” Vinyl answered, her horn lighting up and rapidly pulling out the changing mat. She gently nudged Octavia onto it and began to bring out the rest of the supplies. A thick diaper was slipped under her, grey legs lifted up and powdered before settling back on the comfy layers of cloth. Humming as she worked Vinyl took the time to thoroughly powder her foal, making sure not only that she was covered properly where her diaper would go but also that she would smell like foal powder. Octavia knew what Vinyl was doing, but kept silent. She did open her mouth to protest, but hesitated and closed it.

Her pacifier was her reward, one of the smaller ones that wouldn’t impede her speech. Octavia suckled on it as Vinyl put away the powder and began to fold the diaper up, tugging her tail through and pinning the diaper firmly in place. The same crinkling plastic pants slipped up her legs next, the cold plastic sending a shiver through the earth pony mare.

“Sssh.” Vinyl murmured softly, patting her tummy. “You’ll be all warm and cosy in just a sec, promise.”

The pacifier suckling mare just nodded. A onesie was brought out, but not the one she had worn last night. This one was white with purple trim accented it, made with rather more lace and frills. The shoulders were puffed up balls, short sleeve orbs trimmed with purple lace that matched her eyes and cutie mark. Around her neck a sewn-in bib covered her chest, a square of shiny satin lined with musical notes embroidered along it. Four rings of the same purple lace circled around her back and front, a final tuft of lace around the hole hugging her tail.

Octavia started to get up but Vinyl pushed her back down before she was halfway up. “Uh uh uh.” She warned, shaking her hoof at Octavia with a smirk. “Mama ain’t done yet Octy. Sit down until I’m done.”

She obeyed, cheeks red at how she just complied without thinking about it. A meek “yes mama” was all she said.

Vinyl’s smirk became a smile when Octy called her that. “Good girl.” She patted her foal’s diaper, horn glowing. Four little matching booties floated over and a bonnet. “I don’t know where you got this stuff - oh, right, I do! Haha, I forgot. Got caught up dressin’ my little filly.”

Hearing Vinyl coo, especially towards her, was new and odd to Octavia but she found that she liked it. It was uncomfortably close to being talked down to, which she utterly couldn’t stand, but Octavia would be lying if she said she didn’t enjoy it when Vinyl spoke to her like she really was a little filly in her thick foal’s diaper.

Being so casually addressed by Vinyl as hers made her heart warm up. It wasn’t romantic, as far as she could tell, but she loved it nonetheless. She was Vinyl’s little filly and she liked that. It made Octy smile.

She blinked, realizing she had missed a lot of something Vinyl was going on about.

“-so tomorrow, we’ll swing by so I can have a look and decide on what else you need.” Vinyl was saying, her attention on the last of the booties she was tying on. The bonnet floated up, laces slipping under Octy’s chin and tying into a tight but not uncomfortable knot.

The grown foal didn’t have to look to know the knot was tighter than any she could undo even if she could have gotten at it. Like the booties, her bonnet would need Vinyl to take off. She suckled, her shy smile growing.

If she was Vinyl’s little filly, than meant Vinyl was her mommy.

Her mommy’s hoof tightly smacked against her diaper to get her attention. Vinyl grinned and pulled her up, settling her overgrown foal onto all fours again.

“Spacing out? Yeah, I guess I am pretty awesome.” She said modestly, laughing. To her surprise, soft giggling joined her. “Well well well, looks like my little girl can giggle after all. And here I thought the stork dropped you off without a sense of humor.”

Giggling gently, Octavia’s smile grew. She relax, going from her normal tense, high-strung stance to something more lazy. Foals didn’t need to walk like a proper mare. Foals only had to waddle, and sometimes not even that! That secret delight she got from rebelling against her prim and proper upbringing began to bubble up and as she waddled a few steps, throwing her bootied hooves around Vinyl’s neck.

“Fanks mama.” She lisped, this time by choice rather than because of a big pacifier.

The unicorn was surprised by the sudden hug but hid it well, throwing her own around Octavia. She stroked the lenght of the black mane that wasn’t covered by the bonnet.

“Hey, only the best for my foal.”

Octy’s hug got tighter and they stayed like that until a loud grumble ruined the peace and quiet.

Vinyl pulled back slightly, giving Octavia an amused look. She knew she hadn’t done it herself, so it just left the now blushing earth pony filly in front of her.

“Sounds like Octy is hungry.” Vinyl cooed, rubbing a hoof against the big foal’s tummy through her onesie. “Octy want yum-yums to fill her belly?”

The delightfully childish way her friend....her mama was talking to her just made Octavia giggle uncharacteristically through her blush. She nodded, holding out a hoof expectantly.

Bemused, Vinyl took it and turned, leading her foal out to the kitchen. It was slow going in the thick diaper and the booties which reduced her traction somewhat. They forced Octavia to make slower, more careful steps with some of her weight balanced on the hoof being held by Vinyl. The end result was Octy waddling along like a foal learning to walk, her hoof held the whole way by her mommy as she took wobbly steps.

“Almost there.” Vinyl promised her, the wood-polished timber floor that went from the front door in a straight line down the hall which their rooms and the open, carpeted lounge room all surrounded. “Come on Octy, nearly to the carpet, it’ll be much easier there.”

Being led along by a pony whose posture she had been openly criticizing since they met, each step treated like it was an achievement she should be proud of rather than something perfectly normal, did nothing to diminish Octavia’s delight. In fact it made her enjoy it more. Right now she didn’t feel like Octavia, perfect paragon of manners and propriety. She felt like Octy, Vinyl’s waddling little foal who needed her mommy to help her walk down the hall without tripping.

“Theeeere we go.” Vinyl eased her onto the carpet and gave her a wide, proud smile as she took her first waddling steps off the hall’s polished hardwood floor. She gently patted Octy’s padded rear, enjoying the feeling of the thick padding around her friend’s rear-end. The way Octy squeaked when she did it was adorable.

Adorable. She hadn’t used that word much until this whole thing came out. Now she couldn’t go two seconds without thinking about how cute or adorable Octavia was. It was impossible not to. For a mare who preferred to keep things cool, awesome or radical she was getting used to a lot of cuteness. She had never been a mother before, to a real foal or a bigger than normal one, but she was feeling more like one than she had in her life. It was comfortable to think of Octy as her foal, as her little filly. Because she was.

She smiled at the big foal, who was getting her big diaper on the floor with her back legs spread limply and her fore hooves resting on the ground without much weight to them. Octy smiled back, her pacifier constantly moving as she suckled on it.

“You’re pretty good at that Octy. Waddling along like a happy lil’ foal. Whose mommy’s little waddler?” Vinyl sat next to her, one hoof stroking mane and the other giving the front of her diaper and affectionate rub.

Blushing bright, Octy spoke up in a foalish lisp. “M-me mama!” That waddle had released her and now she felt nothing keeping her from acting the way she really, deep down, wanted to. “‘m mama’s widdle wad-dal-ah!”

Vinyl chuckled at the way her big foal carefully pronounced the word, as though she was unsure how to say it properly and doing her best to copy her mommy. “Yes woo are.” She cooed, shifting the bonnet to plant a brief motherly peck on Octy’s forehead. “And your mama is very proud of you.”

With a giggle, Octy pressed her bootied forehooves to her blushing cheeks and looked away. “F-fank woo mama.” She lisped shyly.

A smile tugged at Vinyl’s lips as she heard her normally carefully enunciating friend lisping. But really, this wasn’t her normally carefully enunciating friend lisping. It was her cute, helpless little foal rocking back and forth on her diaper with a wide smile on her face, framed by a soft purple lace. Her friend had gotten home for the day and retired, leaving just Vinyl and her foal.

“Maybe one day, you can walk all the way on your own. Maybe. But not for a very, very long time.” She told the filly as she took her hoof again and pulled Octy over to the square blanket, toys laid out around it. “Mama is gonna get some din-dins ready, so you be a good little girl and play here, okay?”

Octy nodded, looking at the selection of toys. Her entire world was framed by lace and maybe that was why the lacy, frilly dolly was the first toy she picked up. She plopped down, binkie bobbing in her mouth as she began to play, frilly hooves bouncing the doll along.

Vinyl stopped at the open entrance to the kitchen, her smile soft and warm, not like her usual wild grins and smirks. It was certainly not her perfectly poised flatmate slouching on the blanket over there, surrounded by stuffed toys and blocks. It was her wonderful, cute filly. Of course, if she was Octy’s mama, that made the earth pony filly her daughter.

Humming a song she didn’t realize was a nursery rhyme, Vinyl began to get dinner together. She hadn’t given it much thought before now, but she was confident she could get something together. Checking on Octy every five minutes, and deciding to get a set of foal monitors as soon as she could, Vinyl proved that just because she was a mad-house rocking DJ didn’t meant she couldn’t cook.

It was pasta again, but with some more vegetables thrown in so she thought it counted as a different meal. Now she was going to need something way better to make up for it tomorrow night, but she would cross that bridge when she came to it.

Octy was engaged in a very important game of ‘making Miss Frilly dance’ when her mommy interrupted, saying her din-dins were ready and her doll had to stay out here or she might get messy.

To Vinyl’s surprise, Octy protested. She made a loud whine, not moving from her spot and hugging her doll.

“Dun’ wanna weave her.” Octy announced with a pout. “Get wonwey.”

“I’ll be at the table with you Octy.” Vinyl pointed out.

Octy shook her head. “No, she be wonwey.” She said, holding up the toy.

Giggling slightly and trying to sound authoritative anyway, Vinyl gave in to the cute foal’s expression. “Okay, but she has to sit on the table where I put her so she stays clean. Will that make you happy?”

Apparently it did and Vinyl led her filly to the kitchen, wondering at how dedicated Octavia was to being like a foal. It was astonishing how easily she was slipping into the role, acting it out without actually really acting.

On the inside, Octavia was squirming and blushing in both thrill and embarrassment. She was being so very childish and she loved it. It was just so easy to do, without even thinking about it. She beamed as a bib was tied around her neck and the first fork of pasta was levitated up to her. Mouth wide open, some still managed to get smeared on her cheek and lips. She didn’t mind, not even when some got on her nose. It just made her giggle.

“Open wide, here comes the Friendship Express.” Feeding herself as she fed her foal, Vinyl relaxed and enjoyed the simple meal. Getting the food into Octy’s mouth when the filly seemed intent on trying to lean forward and get it when she least expected it, throwing them both off and risking a mess, just made it more interesting.

But the meal was eventually done and Vinyl had to wipe Octy’s face clean with her bib, removing it and ushering the big foal back into the lounge room with her dolly.

“Mama!” Octy cried not half a minute after she had been left there. Vinyl’s head came through the kitchen door. “Watch me make Miff Fwiwwy dance!”

“Mama’s gotta clean up, then I’ll watch you play.” She promised, suppressing her amusement. Pulling her head back in, Vinyl sighed but smiled. Looking after Octy was requiring more effort than she put into most things aside from her music. After another few minutes, and a whine from Octy, Vinyl was done and she trotted out. Vinyl patted her on the head and got on the couch. It gave her a height difference that pleased Octavia’s desire for foalishness and the earth pony filly began to show her mama how her doll could dance.

It was one of the cutest thing Vinyl had seen and she was worried she might somehow get some sort of magical cuteness overdose. There had just been so much. If cuteness could be weaponized, Octy would be a deadly.

When the show was done Vinyl gave her a loud clap, hooves knocking together.

“Mama’s little girl is quite the talent filly, ain’t she?” Vinyl got off the couch and gave Octy a hard hug. “I think we’ll get you another dolly tomorrow when we visit this store of yours. How’s that sound?”

Octy nodded her eager agreement, hugging her mama. “Gweat!”

“Awesome.” Releasing the overgrown foal, Vinyl left her to play for a minute. She came back with a book. Octavia noticed this oddity and watched Vinyl as she lay on the couch, book spread out in front of her.

After a minute of feeling like she was being stared at, Vinyl looked up. She could tell what her friend was wondering.

Vinyl sighed. “Oh come on, its not that weird to see me reading a book!”

Octavia said nothing, just looking at her.

“....fine, yeah, shut up.” Vinyl grumbled. It was unfair that even dressed like a foal with a thick diaper on her butt and a doll in her hoof, Octavia could give those looks. “I’ve been reading it before bed in my room, okay? I was kinda embarrassed to be reading such a trashy, ugh, romance novel like this and didn’t want you to see.”

The diapered mare binked, clearly not expecting that answer. She focused on the book. It was a romance novel, of a rather mushy sort if she remembered right, and her surprise grew. Vinyl liked reading books like that?!

The DJ chuckled. “Yeah, I know. Totally didn’t expect it, did ya? Well, more to this mare than meets the eye. I figured if you could sit in a diaper and play with foal toys in front of me, I could read a mushy romance novel in front of you.” She explained.

Octavia nodded slowly, smiled without saying anything, and just like that Octy was playing with her toys again. Watching her filly for a few more seconds, Vinyl eventually went back to her book. The clock ticked, time passed as they enjoyed a simple, pleasant evening.

Yawning, Octy was glancing at the clock and worried mama would forget her bedtime (even if it was a friday night) when the first feeling hit her. The first strong feeling, since she had been ignoring the grumbles and rumbles in her gut for at least the past hour as she played. Now she felt it really hitting her. Octy hunched over, trying to hold it in as the pressure began to grow. She kept herself from making any noises, focusing on containing her suddenly unignorable bowels.

Vinyl looked up quickly once she realised Octy had stopped moving. When she saw her big filly hunched over she was off the couch and gently lifting Octy’s head up to look at her in seconds.

“Octy, what’s wrong?!” She asked, eyes darting around as she tried to figure out the problem. “You’re not sick are you? Stomach ache? Cramps? Hemorrhoids?”

Octavia gave Vinyl a dry glare for a moment at the last one. Octy shook her head. “N-no mama.”

Vinyl gulped, worried she had done something wrong on the second night. First, if you didn’t count the night before. “Okay, so, none of those. What’s wrong then?”

A gassy release, just hearble by Vinyl through the thick padding, told her.

Octy said it anyway, blushing brightly. “Mama, g-gotta go poopy.” She squirmed, trying to get up. With a squeak she went back down, feeling her control slip. She really shouldn’t have ignored it all night until now.

It was fairly obvious why Octy was staying put, and Vinyl gulped. She had been hoping to avoid this, but one look at the grey mare’s face told her she had to do something. She could see the fear in Octavia’s eyes as the mare sniffled. Surely this, surely a messy diaper was beyond Vinyl’s limits. It was disgusting, wrong, foul-

Vinyl patted her on the shoulder. “Sssh, its okay Octy, mama’s here. Just...let go, and I’ll clean you up clean.” She promised gently, reaching down to rub the back of her play-daughter’s diaper.

Sniffling slightly, looking at her disbelievingly, Octavia opened her mouth. A white hoof nudged her binkie back in as it started to fall out, silencing her before she started.

“I said I’m here.” She repeated, her other hoof still making a circling motion on the back of the thick diaper, pressing against it through the onesie. “I’ll deal with it, I promise. All you gotta do is trust me.”

Gulping, Octy nodded and stopped trying to hold it in. Once she did, it was actually slightly hard to get it out and she lifted her rear up into the air. She shuddered, gassy fart sounds coming from her diaper as she filled it with the mess two nights of pasta had given her. Her cheeks were even redder than ever and Octy looked down, staring at her bulging rear. She shuddered again, feeling the warmth of her messy against her rear. At least her weight wasn’t mashing it against her, and when Vinyl gently helped her up the unicorn made sure to keep her from tipping onto her butt.

They walked back towards Octavia’s room, and this time they were truly very careful. Octy waddled along, sniffling as her mother held her steady and kept from falling on her messy behind. Vinyl knew tears would result if that happened and she couldn’t stand to see her little girl crying. She cooed and murmured reassurances, her attention never wavering from Octy as the big foal waddled carefully along.

Just as they reached the door Octy put her hoof down with just the wrong weight behind it and she slipped. A whimper escaped her pacifier covered mouth, the shield covering her lips but not stopping the sound. She closed her eyes, expecting to feel her mess squish against her rear. She was almost going to cry before she actually hit the ground.

Except she didn’t.

“Sssssh, its okay, mama’s here. Open your eyes Octy, mommy’s got you.” Vinyl’s reassuring voice cooed to her in the gentle tone that seemed reserved just for her foal. “Gotcha, come on, up we get.”

Gently she eased Octy back up, her horn’s glow vanishing once she was stable. She helped Octy through the door into Octavia’s spotless bedroom, nuzzling her. Octy returned the gesture, cooing non-sensibly as she just pressed against Vinyl, hooves around her neck in a tight hug.

“Hey, I told you I was here, didn’t I?” Vinyl grinned, easing out of the hug to get the changing mat. She patted it and helped Octy lay down, making sure to do it softly and keep the foal’s weight off her diaper.

The onesie’s rear was opened and rolled back, then down came the plastic pants. The smell was contained by the diaper, one of the perks of the high quality that came from Amber’s All-Age Nursery, until Vinyl popped it open.

“Wowsa!” Vinyl rocked back, waving a hoof in front of her muzzle, trying to get the small away from her nostrils. “Octy’s a stinker all right!”

Octy blushed but a reassuring smile from mama told her it was just a joke. Vinyl made sure she didn’t give any sign about how icky it was right now, as she magically lifted up the wipes. But she had cleaned up messes as bad as this, and possibly worse, after big parties and a gew gigs that had gotten out of hoof. A lot of wipes were used. A lot. Vinyl was just glad they were going to the store tomorrow, because they were definitely not stocked up enough to survive another stink-bomb. The bulk of the mess was thrown in a plastic bag, summoned by Vinyl from another room, along with the wadded up wipes. She had been thorough, wiping up every trace and using a warm, moist hoof-towel to make sure Octy was clean but tomorrow Vinyl decided she was giving her little girl a bath before they went out. Octavia would have her head if she let her go out, all prissied up with her bowtie and all, with some crap on her butt.

The squeal when she started with the hoof-towel was worth any annoyance from Octy. She was perfectly clean now, but a bath never hurt. But right now it was bedtime.

Octy was soon wrapped in a soft, clean diaper and it was like heaven to her. She patted it through her onesie, smiling as she bounced on it while mama went away to dispose of the mess and put the diaper in the tiny laundry room. A room with just enough space for one pony, a washing machine and a clothes dryer were worth their weight in gold, at least to an Adult Foal. She was still playing with her diaper when Vinyl came back, the unicorn grinning.

“Guess that’s tonight drama done. Last night it was Lyra Bitchstrings, tonight it was this,” Vinyl chuckled. She patted the bed and let Octy get it before pulling the covers up. The doll Octy had been playing with appeared, Vinyl having grabbed it on her way back. She tucked it with her foal, enjoying the happy squeal she made and the hug Octy gave the toy as she beamed at her play-mother.

“Vinyl...” Octavia said around her pacifier, her smile wider than ever. “Thank you. So much.”

Smirking, Vinyl shrugged. She tried to pretend she wasn’t blushing. “Hey, it’s nothing. I enjoyed it too ya know, so it’s not like it’s all for you.” she teased, making sure the covers were tucked in tight before leaning forward and placing a motherly kiss on Octy’s forehead. “Night night Octy, mama will see you in the morning.”

Octy smiled back. “Night-night mama.” she cooed, snuggling down with her toy. She closed her eyes, only reopening them when the light was turned off and Vinyl was just visible in the light coming throught the door.

The mares exchanged smiles, both happy and both thankful for what they got to experience.

}-{

Several blocks away, Lyra wiped tears from her eyes. She shoved the box back into its spot, a wet cloth in her magic wiping from her rear the clinging powder.

“No no no no no!” she ranted, panting and shaking her head. “G-gotta be normal.” The unicorn sniffled, throwing the wet cloth away. Guilt ate away at her for what she had done, for what she had just spent the evening enjoying. It was wrong, she knew it, just plain wrong. Her desires were wrong, her wants were wrong, she was wrong.

Sobbing to herself Lyra curled up in bed. She knew even as she called herself names that she would go there again tomorrow for more. She had used up the last one, ripping it apart in a frenzy of guilt and self-loathing built up over years. Pillow over her head to muffle her sobbing, Lyra eventually fell asleep. Even in her dreams she heard the giveaway crinkling of them, and she hated herself for it.

Chapter 5

Octavia yawned as she sat at the kitchen table, her mane uncharacteristically tangled and messy. She rubbed her nose tiredly with a hoof, blinking slowly as she suckled on her pacifier.

“Mama!” She whined suddenly, the word coming out nasally and foalish.

“It’s coming! Impatient, aren’t ya?” Vinyl snickered, flipping the pan and sending the pancake flipping into the air. “Oh yeah, style!”

The big foal giggled, slumping on her seat and yawning cutely again. She ran a hoof over the bib around her neck, the only thing she was wearing other than her diaper. Her hoof banged on the table top. “Hungwy!”

Rolling her eyes at the foalish demand, Vinyl Scratch flipped the pancake a final time, landing it on the plate of other pancakes next to her.

“Pancakes for breakfast two days in a row, I’m spoiling you,” she grumbled with a small smile as she put some on Octavia’s plate and some on her own. “Now, can Octy feed herself or does she need Mommy- ”

Octy had already opened her mouth, sitting there with it gaping wide open expectantly.

Vinyl laughed, grinning widely at her. “I guess that answers that. Alright Octy, here comes the wonderbolt!” She sliced a piece of pancake up and the fork lifted into to her foal’s mouth. She chomped down on it happily, devouring each portion as it was fed to her.

I gotta remember this, Octy is better at being a foal when she’s still sleepy, Vinyl thought as she fed herself at the same time. She’s loosening up.

It was a warming thought, that Octavia was beginning to get more used to this. It was still a bit awkward at times, like when Vinyl had woken her and Octavia had looked all cutely embarrassed and flustered as Vinyl ‘hinted’ that if she needed to go potty, she should do it in her diaper before Vinyl pulled away covers.

“I hope when I see your diapee that little Octy has gone pee-pee in it, or Mommy might start doubting her foal’s enthusiasm,” had been her exact words. They had worked too, after a look of nervous anticipation on Octavia’s face. She had scrunched up her cute face with the most adorable look of effort as Vinyl got her out of bed, and lo and behold when her onesie was opened a warm, yellow diaper was waiting to be removed.

Octavia flushed as she let her friend turned caretaker feed her. She didn’t need to be fed, but with nothing pressing her time, she found it easy to relax and let Vinyl handle it. Some maple syrup drinked down her chin, onto her bib. Rather than politely wipe it up with a slightly embarrassed expression, as Octavia knew she would have done normally, Octy extended her tongue down, licking it up. A giggle distracted her, and she looked up to Vinyl’s amused expression.

Smiling, Vinyl kept feeding Octy as she began to eat her own serving. It really was a shame they didn’t have a more appropriate chair for Octy, that would make her look even cuter. She mentally added that to the list of things to look for at the store today.  This ‘All-Ages Nursery’ would, she hoped, helped shorten that list. If they were going to do this long term, they were going to do it right.

“Don’t forget Octy, mama’s taking you to your favorite store later. So after breakfast we need to get you cleaned up. Can you take a shower on your own, or do I need to give my little foal a bath?”

Octavia chewed her mouthful for a bit, trying to decide. A blush lit her face as Octy answered, “I-I’d wike a baff pwease.”

The adorable lisp Octy had would have made a lesser mare squeal, but Vinyl just grinned. She was building up a resistance to Octy-based cuteness.

With a giggle of her own, Vinyl fed her another piece. “Well, what goes in gotta come out, so you’re the one who’s gonna be pooping it all out later. Just make sure you tell me before you need to go, okay babe?”

“Y-yeah Mommy,” Octy agreed, spraying bits of pancake over the table. “Gonna tewl Mommy when gotta go potty.”

Talking with her mouth full was horrible manners, Octavia knew that perfectly well. But a foal like Octy would have no idea, so she giggled as Vinyl wiped her face clean of pancake shrapnel. It was so liberating to be free of things like that. She could talk with her mouth full and all Vinyl did was give her a half-hearted warning around her own mouthful, not quite realising why when Octy burst into giggles again.

“Wha? Wh’s funny?” Vinyl asked. She was meant to be the one with a confusing sense of humour. That was part of her charm, finding funny in things Octavia didn’t. Heck, she’d pretend to be laughing at some joke Octavia didn’t get just to annoy her friend sometimes, which fittingly was quite funny.

 Shaking it off as some private foal’s joke, Vinyl kept up the feeding until both plates were clean. Cleaner than Octy, at least. The big foal’s chin and bib had syrup all over them, which she was happily trying to lick up. Taking away the plates to rinse, Vinyl snickered at the foalish mannerisms her friend was managing now. More syrup she licked up, less work for the only adult there.

“Alright, let’s get you cleaned up. Up ya get Octy, come on,” Vinyl urged her. She took her foal’s hoof when she was standing, leading Octy to the bathroom. Leaving the messy faced foal to sit and wait, Vinyl start running the bath. Warm water, hotter than she’d use for a real foal of course, that she let only slightly fill before turning off the tap.

Striping off Octy’s diaper and bib, Vinyl helped her into the water.

“Now, sit down and let your Ma clean ya, got it?” Vinyl ordered. Octy nodded, fidgeting in the water that came up only to just about her cutie mark as she sat in it. A cloth floated up in Vinyl’s magic, a bottle of liquid soap squirting it before she put it down. Standing at the tub’s edge, she took the cloth and began to clean the foalish mare.

Being cleaned by somepony else was just one more thing for Octavia to add to the list of strange, wonderful new things she was getting to experience. She was happy to relax and let Vinyl clean her, closing her eyes and sighing happily as the cloth was run over her face. It felt so strange, being touched like this. Another pony was the one holding the cloth that was cleaning away the syrup on her face. There was such a difference between cleaning herself and this, like there was with diapering herself and having somepony else do it. It changed the act in some very special way.

All too soon, Octavia found herself being rinsed off by another cloth and being drawn out of the bath. She whined foalishly, shivering slightly until a towel was brought over.

“Hey, calm down, nearly done,” Vinyl soothed, nuzzling her. “Let’s get you dry, and then-”

“Diapee?” Octy gave her a pleading look.

Vinyl shook her head, chuckling. “No can do Octy. We’re going shopping, remember? You’re gonna have to be a big filly, at least until we get to the store, okay?”

Pouting like the foal she was happy to be at home, Octy nodded and let her mommy finish drying her. She didn’t have to worry about going out to the store with Vinyl right now, because so long as she was a foal her Mama was making decisions. All Octy had to do was sit there and let them happen.

So when she stepped from the apartment, both wearing saddlebags, and she went from being Octy to being Octavia, she got to have all those worries come crashing down on her. It was so much easier when she could just stop thinking and stop worrying about

“Maybe this isn’t such a good idea,” she said nervously, coming to a stop.

Vinyl rolled her eyes. She had been expecting this. She wasn’t worried, for a very good reason.

“You know, maybe it’s not. But then again, even if you don’t go I still will,” the DJ said. She smirked. “Hey, ‘Tavi, did you remember to get your key for the apartment?”

Octavia scowled. “Of course I did, it’s right-” she shut her mouth as she realised she had let Vinyl do all of that. The unicorn grinned widely at the look her friend gave her. “Cheater.”

“Ain’t cheating if you never told me not to. Since we’re out, and I’m gonna go anyway, you might as well come with me,” Vinyl pointed out with a fiendish chuckle. “After all, this way at least you can certain the stuff I get you fits properly.”

Letting out a sigh of defeat, Octavia nodded. “Fine, fine. If you really must lower yourself to such crass tactics-”

“I must!”

“Be quiet! If you must do so, I suppose my only choice is to accompany you and keep you out of trouble. I can see it now ‘DJ causes disaster at Adult Foal Store - Classical Musician’s secret revealed!’” the fancy mare grumbled.

Vinyl grinned at her as they set off. “Come on ‘Tavi, if that happened why would you get caught up in it?”

“Because I always do? Honestly Vinyl, it’s like you can’t cause chaos without somehow dragging me in.” With each step, Octavia felt more and more like, well, Octavia. A full grown mare. An adult. An adult who could give her best friend a quite serious talking to.

“What about that time in Las Pegasus? You weren’t dragged into that, and I had a hoof-fight with that drag queen in front of the hotel owner,” Vinyl argued, although she wasn’t exactly making a good case for herself in general.

“I had to come and pay bail.”

“Huh….so you did.”

They trotted languidly through the city, enjoying the warm, bright summer’s day. The air was fresh, the ponies around them were colourful and polite. They were getting closer and closer to one place Octavia could find things to add to her fantasies. Nothing, Octavia was certain, could ruin this day.

}-{

Lyra ate alone in her tiny apartment, eating her breakfast. Normally she loved Apple Jacks, but one glance towards the bin reminded her of where she was going. Of what she was going to do. The bin held the torn remains of her curse. It had to be a curse. Lyra dropped the bowl in the sink when she was done, rubbing a hoof across her forehead.

I don’t have to go, she thought to herself. I don’t need to go...

One look towards the bin and Lyra knew she would give in. Maybe not today. Maybe not tomorrow. She had gone a month once before giving in and restocking. But that didn’t matter. It didn’t matter how long it had taken, she had given in. She had given in and bought more, to her shame.

Once she had admitted to herself she would go back again, Lyra had no trouble deciding to get them today. It always made her anxious, wondering if she’d get caught on the way there, or the way back. She might as well go now, she decided, and get it over with. Once that was done, she could lock them away. Lock them away and forget about them for as long as she could.

Besides, she rationalised, she could control it better like this. She could prove to herself that she wasn’t doing it, that she was choosing not to be a freak, if she had them but didn’t use them. It all made perfect sense. If she didn’t have any, not wearing them didn’t mean anything. But if she had them she could prove to herself she was stronger than her addiction.

Her decision explained to herself far more than she should have needed, Lyra quickly pulled on her saddlebags and left her apartment, locking it. She stepped out in the light and winced, finding it too bright after her low light home, before setting off. She almost subconsciously kept to the shadows, feeling as though anypony who looked at her would somehow know what she was doing. That they would know what she was. It was irrational, but the idea that her strangeness somehow showed was one she just couldn’t shake.

Torn between her desire for that soft, reassuring padding and her desire to be normal, Lyra trotted through the city, trying to work out how she felt.

}-{

Octavia fell silent as they approached the store. It was normal on the surface, a pharmacy tucked into a normal, entirely ordinary street. Inside it seemed only to contain a range of items for your every medical need. Well, not every, but a lot. Amber’s Pharmacy supplied what you needed with experienced advice and helpful hooves. For those with embarrassing needs, Amber guaranteed privacy and discretion.

Privacy and discretion were very important, especially where her other store was concerned. Through a door at the back of the store, Amber All-Ages Nursery Store provided everything any adult foal could need. The owner’s understanding and cheerful nature helped many who found it an ordeal, although some more than others.

Vinyl went in first, glancing back at her friend. Just outside the door, Octavia hesitated. Her nervousness returned. Their bantering and bickering had made it go away, letting her relax, but now the grey mare found her nerves coming back.

“Maybe we shouldn’t-” she began.

“Too late!” Vinyl grabbed her by the hoof and yanked Octavia in.

“Welcome!” A cheerful orange pegasus greeted them as they stepped in. Well, Vinyl stepped in. Octavia was dragged in, but that was close enough. “Is there anything I can help you with- Oh! Octavia! Hi!”

Blushing, Octavia gave the pegasus mare a remarkably timid greeting for her. Having no compunctions, Vinyl was much more willing to meet this new pony.

“Hey, nice to meet ya. Octy and I are here for…” Vinyl glanced around just in case, but the sore was otherwise empty, then nudged Octavia. “Go on, tell her.”

The blue-maned pharmacist cocked her head to the side, looking at Octavia. She was not an adult foal herself, but she knew most in Canterlot. Her store was the only one there, and she went to great pains to reassure her customers.

“Uh, we, ah, we’re here to…” Octavia cringed, looking away with a flush under her grey coat.

“It’s okay dear. Do you want me to show you to the back store?” Amber asked gently.

Octavia nodded in relief. She didn’t have to say it. “Y-yes, please-”

“Hang on a sec! ‘Tavi, come on. There’s no reason to be embarrassed,” Vinyl said, putting a hoof around her friend. “I know it’s hard, but it’ll help. You’re acting all, you know, prissy about it. Just say it, there’s nothing wrong with it.”

Taking a moment, Octavia sighed. “I...suppose you have a point. Amber, we’re here for the...the back store.”

It wasn’t much, but it was more than she had managed. The first time, Amber had recognised the blushing, stuttering mare’s purpose and gently helped her.

“Well, alrighty then! Come on!” Amber said brightly, beaming at them and leading them back. A pale pink door led to a short staircase with a baby blue door. “Will you need any help?”

“Nah, Octy knows what she wants,” Vinyl said, grinning widely. “We should be fine.”

“Okie-dokie! I’ll be upstairs if you need me, just ring the bell if you want to make a purchase,” Amber smiled and went back up as her customers went into the back store. Octavia’s visits had been less frequent recently, usually only every so often to get more diapers. She hadn’t bought any clothes in ages either, which was such a shame considering some recent items. Amber hoped she and her friend found the dress, it matched the white and purple onesie Octavia had purchased.

Vinyl whistled as they stepped into the All-Ages Nursery store. It was like a foal store, except...bigger. Everything on offer was bigger. There was a sign with helpful directions, describing products and showing which aisle they were on. Amber had done her best to ensure customers could browse to their pleasure without feeling like she was watching them. A tug of the rope marked ‘bell’ would let her know they wanted to make their purchase, and it could all go ahead without customers to the upper store being the slightest bit aware.

“Wow, there’s a lot here! Diapers, diapers, diapers, disposable diapers, cloth diapers, foal powder, clothes, toys...seriously, damn!” Vinyl was clearly impressed, and trotted about the store looking. The fact it was an adult foal store, a place she had never stepped hoof in before, was ignored because Vinyl scratch did not let things like that stop her.

Octavia watched, looking around uncertainly. With just Vinyl, the mare who had changed her wet diaper, fed her and bathed her, she began to relax.

“Yes,” she agreed. “Amber does have quite the wide range of items. I’ve been coming here for quite a while, and she is constantly trying to get better quality and more options.”

“Cool, is she an adult foal too? Hey, this dress matches your onesie!” Already looking around, Vinyl floated over a dress in a purple that matched Octavia’s cutie mark, accented with white frills and trim. “Come on, try it on! I saw a changing stall over there!”

Giving a sigh that was mostly for show, Octavia agreed. It fooled nopony, Vinyl grinning at how eager Octavia was. Stepping into the changing room, she held out a hoof for the dress. Instead she got a whole pony.

“Not expecting me to let my little filly dress herself, now are you?” she asked cheerfully.

“Of course not,” Octavia blushed but stepped aside for Vinyl to come in. She had forgotten about her bowtie, so there was nothing to remove. It took her a moment to realise there was another dress, a soft pink foal dress. It was shorter, its color close to her bowtie’s, and decorated with a number of bows. “Really?”

Vinyl just gave her a cheeky grin in answer. “Never go in with just one thing to try on, Octy, keep up.”

The use of the foalish nickname sent a warm flush through Octavia. She let Vinyl slip the purple dress onto her, buttoning it up behind her. A sash just below her ribs was pulled up and tied into a bow on her back before she was turned to look at herself in the mirror. Octy didn’t have any foal dresses yet, but she was entranced by her reflection. She could just imagine her thickly padded rear framed by the frills of the hem.

A white leg curled around her neck and Vinyl grinned at the mirror. “How’s that? Love it?”

Octy nuzzled Vinyl, the sudden affectionate gesture taking the DJ by surprise. After a moment the unicorn laughed happily.

“Yep, you love it.”

Preoccupied with playing dress up, they didn’t hear the door to the upper store opening.

Amber gave the mint mare a warm smile. Lyra’s visits were always a bit sad. She just hated to see somepony looking so guilty when they were here. The best she could do was offer a kind smile and a non-threatening presence when she came in to get more supplies. Amber only knew her name from seeing a performance in one of Canterlot’s many parks where Lyra played quite beautifully. She hummed the tune to herself, going to the counter. This time it was just diapers, it seemed. She knew it was just diapers, given the way Lyra hurried straight to the diaper aisle. There were many patterns of behaviour with her customers, and when she was here for more supplies Lyra went to the diaper aisle last. It was delicate science.

Lyra looked up and down the range of brands. Amber had the best and the widest range of adult foal diapers. Being surrounded by this treasure trove of foalish items let her ignore the inevitable self-recriminations and guilt, at least for a little while. She could sink into the bubble of safety and relaxation. Perhaps she could get something to wear while she was here...

No! No, just new diapers, that’s all, Lyra thought, shaking her head in silent denial. She grabbed her favourite kind, the very thickest available. They were almost ridiculously big, and she could barely walk in them. Looking them over, she couldn’t help letting out a little squeal. The thicker they were, the longer she could use it. If she could use it longer, she would be able to space them out longer until she needed to get more. Not that she would, Lyra hastily reminded herself. She wasn’t even going to wear them.

Carrying two large packs out to the counter, Lyra thought about that. It really didn’t make any sense, spending all these bits and then not even opening them. For one thing, how could she know she got what she paid for? Yes, she didn’t intend to use them, but that wasn’t the point. It was the principle of the thing! As much as she trusted Amber, she still had to check the product.

By the time she reached the counter, Lyra had decided that she would at the very least open one of them. Not to use them, but to check. She had to make sure she got what she paid for, and not a lot of...of...of paper, or something. Lyra pulled out her bit purse and counted across the coins, and the thought struck her that, well, even if they looked right, she couldn’t be sure they would do what they were meant to. The lyrist nearly nodded to herself. That was just obvious. If she was going to open it, she was going to have to check to make sure at least one worked. The only way to do that was to, well, to wear it. There was nothing for it, Lyra decided. She would have to use one, just one, to make sure she had got what she paid for, and she might as well do it promptly when she got home. Strike while the iron is hot, really.

It was just the sensible thing to do.

Lyra was just deciding she would have to check both pack of diapers to really be sure, one pack stored in her saddlebag and the other levitating over to her other side’s bag, when the sound of a familiar voice became audible. She thought nothing of it, lost in her rationalising her desires to herself, until a moment too late.

“-need that much, really,” Octavia was saying as she stepped from between the aisles. She turned her head, looking to the counter where Lyra stood.

Lyra froze. Her magic just went off, the thick pack of diapers dropping to the floor. Their eyes met. Octavia froze too, her eyes going wide and her mouth dropping open in shock as they stared at each other.

She wasn’t sure exactly what happened. All Lyra remembered when she got home was the sound of her life crashing around her. Everything she loved falling apart. Everypony she loved rejecting her. She remembered the sting of tears in her eyes, but for all she knew that might have been something that got into them on her heedless, headlong gallop from the store. One moment she was staring into Octavia’s eyes, the next she was at home, curled up on her bed. A diaper so thick her back legs had no chance of meeting cuddled her rear, holding her in its tight embrace as she suckled on a pacifier and cried into her pillow, convinced her life was over.

I’m ruined...Bonnie...

}-{

“What the buck was that?” Vinyl blurted, dropping the many things her magic held. “Was...was that Lyra?”

Octavia wasn’t sure what to say, but she did manage a nod. She couldn’t believe it. Lyra. Lyra had been here, at the adult foal store. What could Lyra, who had hurt her so badly when she found out just this very secret, be doing here? Had she followed them, seeking something to hold over Octavia?

No, that makes no sense. She just ran from us, and...and I think she was crying! Octavia’s mind worked furiously, trying to work out what the flying feather was going on.

“What was she doing here?” Looking around in confusion, Vinyl’s sought sign of other ponies. Aside from them, the only other pony was a very surprised and distressed Amber.

The answer was sitting on the floor, the shiny plastic package emblazoned with Fluffy Foals Adult Diapers. Octavia approached the package of diapers she had seen Lyra drop. She stared at it, and started to tremble.

“How….how dare she…”

Vinyl looked up, staring at Octavia. She was even more confused. “What?”

“How. Dare. She,” Octavia snarled. “That...hypocrite! That dirty, filthy hypocrite!”

The door slammed shut as Octavia stormed out. It was a mistake to call her just angry. She was furious.

Vinyl stared after her friend. She looked down at the diapers Lyra had dropped. An idea slowly occurred to her as she stared at it. Hypocrite. She understood that. Octavia had been so hurt by how Lyra reacted when she found out, finding out that Lyra herself was into it must surely hurt even more!

...except... Vinyl took her purchases, along with Lyra’s diapers, to the counter. She reassured Amber but she was thinking about something else. She couldn’t help but feel this wasn’t so clear cut.

One way or another, Vinyl decided that she was going to find out exactly what was going on. Lyra and Octavia were both adult foals, or at the very least into the whole diaper thing. It was something they shared, and as shocking as that was, Vinyl did wonder one thing; If they shared this secret without knowing about it now...how long had they done so?

Chapter 6

Vinyl stared at the door she knew was all that separated her from the home of Octavia’s...well, nemesis. That was how they acted, at least. Like soap opera arch-rivals or enemies or something. Frankly, she thought it was ridiculous and overly dramatic. She stared at the door, unsure if this was the right thing to do. It wasn’t like she was worried about Octavia catching her visiting her apparently hypocritical enemy. The prissy pony had left the store in such a state that Vinyl was nearly completely certain Octavia was home, padded up and punching a pillow. Or maybe punching the whole bed. Hopefully nothing was damaged by the time Vinyl got home.

I better do it now, she thought, sighing. Strike while the iron is hot and all that jazz.

What exactly she was here to do, she was still unsure. Vinyl mostly just wanted to get Lyra’s side of it. There was a possibility here that everything had gone wrong from something that wasn’t nearly as bad as Octavia believed. As much as she wanted to believe her friend, Vinyl knew that Octavia could be unintentionally exaggerating or not remembering clearly thanks to the hefty amount of anger simmering away inside her.

Knocking loudly, Vinyl jerked back in surprise when the door swung open an inch. Checking to make sure she hadn’t just arrived while Lyra was being robbed, Vinyl decided the other unicorn had just left her door unlocked. It wasn’t like Canterlot was all that dangerous, but it wasn’t a town like Ponyville where everypony felt safe leaving their homes open and unlocked. Peeking in, Vinyl looked around. She revised her decision that this wasn’t a robbery when she saw the broken vase in the just inside the door. The stand it had probably been on was next to it, fallen as well.

If it was a robbery, and she really hoped it wasn’t, Vinyl Scratch couldn’t just stand there and do nothing, even if this was Lyra. Pushing the door open and stepping in, she walked around the vase, stepping over the puddle it had left. The apartment was pretty small, reminding her exactly why she had gotten a roommate in the first place.

“And now I’m changing her diapers,” she muttered to herself with a giggle. Quieting herself, Vinyl kept up her search. Nothing else was damaged, the small living room with its kitchenette looking pretty peaceful. Nothing out of the ordinary, just stuff about classical music, books, sheet music, that sort of thing. There was even what Vinyl was pretty sure was a lyre….or a harp. It was a stringy thing that made fancy music. Shaking her head, Vinyl continued her search. The whole time, the apartment was quiet. Too quiet.

“Okay...creepy,” she muttered. There was only one more door, so she crept towards it.  She knocked quietly. “Lyra? Yo, its Vinyl Scratch, you here?”

Silence answered her. She tapped the door again.

“Just wanna talk, you know, about...stuff and...things.”

Okay, that was lame. Come on Scratch, just open it up and check. If she’s here, we can talk. If she’s not, well, I better get out before I get accused of trying to break in.

She grasped the handle and slowly opened it, peeking in. It was dark inside, the only light streaming in from behind Vinyl. It wasn’t completely silent though, and the sound reminded Vinyl of Octy and her favourite pacifier.

Thuckle, thuckle, thuckle.

“Huh?” She squinted and pushed up her sunglasses, making out the form curled up on the bed. Pushing the door open enough to step in, Vinyl’s hoof hit something heavy and plastic. It was, it turned out, a large pack of diapers identical to the one Vinyl had picked up. Fluffy Foal adult diapers, the thickest on the market. Lighting her horn, Vinyl saw the packet was open, the plastic torn messily open, like some animal had ripped it open.

Her magic light revealed the mare on the bed. Lyra didn’t react to the light. She was just curled up, a hastily-taped diaper on her bottom, legs clutching something tightly her chest. The source of the suckling sound, so much like Octy, was the pacifier the musician was suckling on.

Thuckle, thuckle, thuckle.

‘Well, I guess that puts any doubt to rest...why isn’t she doing anything?’ Vinyl wondered. The light should have gotten some reaction out of Lyra.

“Lyra?” She waited, but got no response. “Lyra, stop ignoring me, I just came here to talk. I’m not gonna make fun of you or anything, come on.”

Still Lyra did nothing. She just lay there, hugging what looked like a soft toy and suckling on her pacifier like it was the last one in the world. Vinyl frowned. She cautiously approached the bed, until she was right in front of the other unicorn, who just stared straight through her.

“...okay, this is definitely weird.”

She finally went for her patented perfect pony prodding technique; she poked Lyra. When this didn’t work, she poked her again. Vinyl frowned, reaching over to poke her again.

“Lyra, stop ignoring me. We need to talk. Come on,” she urged, poking her again. Poke. Poke. “Damn it, stop playing games!”

To her frustration, Lyra didn’t do anything but suckle. She was staring at the wall, her eyes red and damp, lines painted on her cheeks where she had been crying at some point. Clearly just poking her and shouting weren’t going to do anything. By now, Vinyl was starting to worry. This was weird, really weird. Not the diapers, but the way Lyra just seemed to be completely gone.

‘Okay, gotta think of something. She’s totally out of it,’ Vinyl thought, rubbing her forehead. She scowled, trying to work out what to do. ‘At least I know she really is into this stuff. I mean wow, look at those diapers, they’re huge! She must really like them.’ She laughed quietly. ‘She’s just like Octy, despite how much they hate each other.’

She stopped, blinking a few times. Just like Octy. Vinyl grinned suddenly, an idea coming to her. Lyra really was just like Octy, and if Vinyl wanted to make her come back from wherever she had gone in her head, all the DJ had to do was do what she did for Octavia. A quick search under Lyra’s bed found a foal bottle, left far out of sight and out of reach for anyone but a unicorn.

Taking it to the kitchen, the unicorn thought more about her idea. Lyra had checked out. Since she wasn’t a doctor or a psychologist or anything, Vinyl couldn’t be sure. But if Lyra had checked out, maybe that meant there was another way to get something out of her.

“Ly-Ly,” Vinyl cooed when she got back, sidling up to the side of the bed. She pressed a hoof against the diaper, feeling it squish slightly. “Looks like somepony wet her diapee. Do you need a changey-wangey?”

Vinyl saw a tiny movement. Lyra twitched, her forelegs shifting slightly. The DJ grinned.

“Or maybe you’re not wet enough, huh? It can wait.” Her magic carried the bottle of warm milk, bouncing it in front of the zoned out unicorn. “Come on sweetie, open up.”

Lyra stirred as her pacifier was pulled out, lifting her head instinctively trying to get it back. But Vinyl’s magic kept it out of reach, replacing it with the bottle. A little squeal left Lyra’s lips as the soft plastic nipple pressed into her lips, but with something to suck on she let her head sink back onto her pillow. By the time she had done that, Vinyl had already hopped onto the bed.

The green unicorn lay there, head in Vinyl’s lap, bottle in her mouth. Her soft, gentle suckling brought warm milk into her mouth as she stared up dully. Vinyl ran a hoof through the overgrown foal’s mane, smiling reassuringly at her.

“See, not so bad. Just relax and let Auntie Vinyl help. The~eeere we go,” she cooed. She let it stop there for the moment, giving Lyra a moment to drink from the bottle.

Slowly, the foalish unicorn began to relax, still staring off without seeing Vinyl. Some part of Lyra still heard her, still knew what was going on. Her forelegs remained tightly clutching what Vinyl could now see was a stuffed toy. Reaching down, she tried to gently loosen Lyra’s grip so she could see what it was. She got a whine from the filly, a wordless, foalish sound of complaint.

“Okay, okay, I’ll stop, calm down.” Vinyl patted her on the head and the suckling started again. She smiled.

 Lyra wasn’t so bad, not right now. For all Octavia’s frequent rants about some frustrating encounter with her, at the moment Lyra was pretty adorable. Her messy mane, foalish suckling and toy, not to mention the thick diaper spreading her legs, added up to one cute foal.

“Gah, you’re adorable. Has anypony ever told you that? You’ve gotta be one of the cutest little foals I’ve ever seen,” Vinyl chuckled. A blush spread under Lyra’s furred cheeks, making the DJ grin. Lyra was coming back, even if it was slowly.

Gently rocking the mare, Vinyl didn’t say anything else. She just relaxed, and Lyra relaxed in turn. She wasn’t sure how long they stayed like this before a quiet, timid voice spoke up. ‘Spoke up’ was really not quite accurate; it was a barely audible mumble.. She looked down at Lyra, cocking an eyebrow down at her. The unicorn flinched and looked away, but didn’t try to move.

“Gonna have to speak up, can’t hear ya. All the loud music, heh,” Vinyl chuckled. She lowered her head to make easier to hear, ears flicking towards Lyra.

“P-please…” she heard Lyra whisper. The mare hugged her toy harder, refusing to look up. “P-pleasedon’ttellanypony.”

“Eh? What’d you say?” Gently shifting the big foal’s head, Vinyl tried to get her to look her in the eye. “Tell anypony? How lame do you think I am?”

Lyra didn’t say anything in reply, she just suckled on her pacifier, staring off at the wall with a blush showing through her fur. The mare fidgeted, eyes flicking up for a moment before going back to staring away. With patience she only displayed for Octy, Vinyl stayed silent, letting Lyra take her time until she was ready.

“Why…?”

“Why am I cool with this? Why did I follow you?” Vinyl asked. She didn’t wait for an answer. “I followed you because I wanted to talk to you. Octavia might have been too angry to care, but it’s kinda hard to just go ‘Oh, Lyra ran crying because we ran into her in the adult foal store, oh well’.”

Cringing, Lyra began to squirm. She stilled when a hoof was put on her shoulder. Vinyl didn’t push her down, just rested her hoof there and Lyra stopped moving.  She gave her toy a squeeze.

Keeping her voice soothing and calm, Vinyl attempted to coax more from her; “Octavia told me a story. It was about the two of you, and you parted ways angry and hurt. Except I don’t think Octavia knew the whole situation.” She waited until Lyra peeked at her again and held her gaze. “Octavia found you with a pack of diapers, didn’t she?”

Blushing, Lyra nodded weakly. Her eyes shiny with unshed tears and she whimpered, “P-please don’t...I-I don’t want to…” She sniffled.

“Do you know why Octavia was so angry with you?” Vinyl went on. She hated to see anypony like this, and with the caustic, razor-tongued Lyra it was even worse because it was just so different from how she normally was.

Tears finally burst from Lyra’s tears. “Because I’m a freak! She found me and my diapers, and she knew I was a freak!” She wailed, covering her face. “S-she’s right, I-I am a freak!”

“Whoa! Freak? Calm down, you’re not a-”

“I AM!” Lyra pulled away, curling up on the other side of the bed. She threw her toy across the room, spat her pacifier out and reached down, tugging at her diaper. “Look at me, wearing a freaking wet diaper, what the hay is wrong with me? Wrong wrong wrong-”

She was cut off by her pacifier. It had stopped halfway to the floor, held in Vinyl’s magic, and rocketed back up to plant itself in her mouth. She turned to glare at Vinyl, wiping futilely at her wet eyes, and the DJ caught her in a hug.

“Shhhh,” she soothed, patting her on the back. Lyra pushed at her for a few seconds before going limp. The diapered unicorn sobbed against Vinyl, going from angry to tearful in seconds. “You’re not a freak.”

“I-I am!” Lyra cried, whimpering around her pacifier. “Octavia f-found out and she hates me!”

Vinyl cringed. “No, Lyra...she thought you had found her diapers. She felt just as embarrassed and ashamed as you do! She thinks you found hers!”

Pulling her head back, Lyra stared at Vinyl in shock. “Y-you’re….you’re lying...she wouldn’t, I mean, Octavia’s not…” She shook her head.

“What do you think we were doing at that store?” Vinyl asked her. She smiled warmly and reached up to wipe away Lyra’s tears. “The same thing you were. Me and Octy were getting her some more stuff.”

Lyra sat there, staring at her in numb shock. Her mouth twitched but she didn’t say anything. It looked like it was too much for her to handle. Years of verbal dueling and sniping were suddenly given a whole new subtext. Octavia hadn’t been trying to belittle and bully her; she had been doing the exact same thing as Lyra, trying to show the other she wasn’t an easy target. They had both been afraid their secret would be revealed.

“Celestia…” she whispered. “She...she’s really…” Her lip trembled. “She...she didn’t think I was a freak?”

Vinyl’s smile became a grin. “Nope! She thought you thought she was! You’re not a freak, Lyra. I promise you, and you know I’m the coolest pony in this city. If I say you’re not a freak, you’re not a freak, got it?”

Dazed by the revelation, Lyra just gave a weak nod. “I- she-....oh Celestia, she must hate me! She must think I’m such a terrible pony!” She trembled, suckling on her pacifier urgently.

“Eh, a bit...okay, okay, calm down,” Vinyl hurriedly tried to take back her words. “We just have to explain this to her. She was pretty steamed after she saw you.”

Sitting back on her thick diaper, Lyra stared at the other unicorn. She shook her head in confusion, uncertain and afraid that a terrible, terrible mistake could never be fixed. She was a freak. She knew that. She told herself every day she was wrong and freakish and...and Octavia liked diapers as well. Prim, proper, always-in-control Octavia!

“I...I always felt so jealous of her…” she hung her head, sobbing quietly. “S-she wasn’t a freak. She wasn’t wrong like me. She was normal and p-proper and she hated me because I’m a freak…”

Vinyl felt like slapping Lyra for being so damned dense. She settled for hugging Lyra even tighter. “Stop it. You are not a freak. You might not be normal, and Octy ain’t either, but there’s nothing wrong with either of you, except you’re both as thick as cement.”

The mint green unicorn tried to nod, but she just couldn’t bring herself to. She pressed her face against Vinyl’s shoulders.  Vinyl stroked the back of the mare’s mane, thinking about how she in no way expected this situation before a week ago. Hell, she hadn’t been expecting it this morning.

“You both need to realise just because you like something a little odd, a bit outta the ordinary, you aren’t freaks. In fact, I bet once the anger wears off Octavia is going to be as afraid as you.” Vinyl sighed, rubbing her forehead. “So, you know what I want to do?”

Lyra gave a little head-shake.

“I want you to come with me to see Octy. Shh, shh, calm down,” Vinyl cooed, trying to soothe Lyra’s fearful whimper. “I won’t let her shout at you, and you won’t shout at her. You’re both going to sit down and talk.”

She was close enough to easily hear Lyra gulp loudly and her low, quiet question; “W-what if she...hates me? E-even after she knows. I’ve been…”

“Yeah, you’ve been a bitch, but hey, so has she! It kinda cancels it out for both of you, since you were both acting mean to each other.” The grin Vinyl gave her assured Lyra that this made complete sense.

Lyra looked at her nervously, biting her lip. “That...doesn’t really help…” Vinyl dipped her head and sighed, but Lyra put a hoof on her shoulder. “But I’m glad you’re trying.”

Vinyl nuzzled Lyra a bit. “Hey, you may be thick as a brick, but that doesn’t mean I can’t try and knock some sense into you.”

“Gee, uh...thanks? I think?” Lyra’s brow furrowed in confusion. She wasn’t sure if Vinyl was being mean or nice.

“So that’s why I’m gonna make you come with me if I have to,” Vinyl went on, the same confident grin on her face.

Lyra looked at her in horror. “Wait, what? No! I can’t… I mean… “

Vinyl wasn’t taking no for an answer. She grabbed Lyra by the hoof and stood her up, making sure she was pointed right at the door. “That’s it, put one hoof in front of the other.”

Mint green hooves dug into the carpet, forcing Vinyl to pull even harder. “No! I-I can’t! What if she still hates me? She’s gonna…”

“If she does or says anything, I promise I’ll get on her case about it.”

“But what about…” Lyra didn’t finish her sentence. She just looked behind her at the poofy padding still adorning her flanks.

Vinyl saw it as well, and sheepishly chuckled. “Um, I guess I should take that off you.” Lyra started to thank her, but found herself lifted up into the air and then laid on her back. Her face screwed up in confusion, but then Vinyl used her magic to undo the tapes and then gently peel back the soggy diaper. Then she looked around and spied a small package of foal wipes. She pulled some out to clean the big foal off.

“I-I can do it myself,” said Lyra.

“I know, but I figured you’d probably like this part anyway. Octy does.” Vinyl’s grin didn’t falter and she was happily candid about Octavia’s foalish fun.

Lyra didn’t say anything, but she admitted to herself that being cleaned by somepony else was a nice feeling. The gentle caress of the wipe on her bottom was soothing, and she found herself smiling at the bliss the small moment was creating.

When Vinyl finished cleaning Lyra’s rump, she looked over at the mare and saw a big, happy grin on her face. “That’s the happy little foal I wanna see,” she said, nudging Lyra’s chin.

Her grin grew even wider. “Thanks, Vinyl. For… for all this.”

“Don’t mention it,” said Vinyl, then she tugged on Lyra’s foreleg again. “C’mon, let’s go.”

Lyra hesitated, her eyes betraying a deep-seated fear that Vinyl attributed to years of thinking she was some sort of monster or something for liking diapers. Vinyl was about to tug a second time, but then Lyra gulped and started to slowly walk forward.

Vinyl’s magic scooped up her saddlebags, dropped when she’d arrived. The package of diapers she had brought to return to Lyra was still in there, and she grinned as she opened the door for Lyra.

Octavia rolled her head over so the tears staining the pillow would stop soaking into her cheek fur. She sniffled a bit and wiped her nose, her forehead feeling sore from the amount of angry frowning she’d been doing. She stared up at the ceiling, her mind still racing and thinking about that… that bitch who had given her so much crap.

An angry, feral cry of pain burst from her. Octavia covered her face, her muffled snarl continuing on as she let out her emotions.

She was furious. Octavia had never been so angry. Pure outrage filled her. Her life since those years long ago had been fraught with bouts of guilt and self-loathing for her strange obsession. Lyra’s reaction had been how any normal pony would react, she had been so certain, and it had justified so much anguish Octavia had inflicted on herself.

Except Lyra was a hypocrite. A lying, filthy hypocrite. That unicorn had insulted her, had argued and bickered and been her enemy all over something Lyra did as well! Octavia’s hoof slammed down down into her mattress, rising and falling again as she tried to let out her feelings.

“I hate her!” she snarled weakly. “H-hate her. D-damn it!”

What right did Lyra have, to treat her like she had? To reject her friendship over something she herself was just as guilty of? How dare Lyra indulge in diapers as well?! How dare she sully something Octavia loved like this?!

Any other mare would have drowned themselves in a tub of ice cream. Vinyl’s consolation of choice was liquor, or as Vinyl would say, a lot of booze. Neither ice cream nor alcohol were much source of comfort for Octavia, however. With how angry she felt the ice cream would melt and the alcohol ignite if they approached her burning internal fury.

She turned her head back to look at the closet. Within it were the objects of shame that she’d only recently in her life begun to accept as a part of who she was. And, she realized, if Lyra hadn’t made her life hell because of her own hypocrisy, she probably wouldn’t have nearly the same amount of scarring that she now carried within her. As she gazed through the slightly cracked door at the wrinkled package on the floor within, she vowed that if she ever saw Lyra again, she would do her best to make her feel exactly what she felt inside.

As she was gazing into the closet, on the other end of the house, Vinyl was opening the front door quietly. She glanced back, giving Lyra a warm smile to reassure the nervous unicorn waiting outside. Lyra returned the smile, although hers was weak and uncertain.

“You just stick around in the living room and kick your hooves up or whatever. I’m gonna go talk to Octy and then we’ll get you in some nice, soft padding, okay? Would you like that?”

Lyra nodded timidly as she was herded inside, with Vinyl making sure to keep quiet. She didn’t want to disturb Octavia, and she figured if Octy laid eyes on Lyra she would probably vaporize her with her gaze alone. And after Vinyl had just gotten the poor mare to open up to her.

“A-are you sure this will be okay?” asked Lyra, her nervousness trickling into her voice. She scanned the apartment, searching for any sign of Octavia about to appear and tear her apart.

“You’re not backing out on me now, are you?” asked Vinyl with a reassuring lopsided grin.

Lyra sighed. “No, I’m not. I’ll...I’ll wait here…”

Nodding, Vinyl left her there, approaching the door behind which she was sure Octavia was fuming. She eased up to the big, wooden obstacle and gently knocked. Octavia whipped her head in the direction of the door. “Vinyl?” she said, her voice still a touch shaky.

“Yeah, it’s me, Octy. Can I come in?”

Octavia made it to “Not” before Vinyl opened the door and stepped inside. She sighed, glaring from her reclining position on her bed. “Yes, what can I do for you, Vinyl?” she said, sarcasm dripping from every word.

“I wanted to talk about Lyra.” Vinyl braced for the explosion. Octavia didn’t disappoint.

“What about her?! That hypocritical, lying whorse!” Octavia’s voice cracked like a whip. Her glare intensified. “Is that where you were, going after her? I hope you gave her a few hits for me.”

Viny’s eyes widened in shock. “Whoa, uh, Octy, I didn’t go after her to hurt her. She’s-”

“She’s horrible! She hurt me, Vinyl! She found out my secret, and ever since she’s been the most horrible pony in Equestria! Nightmare Moon? Discord? The changelings?” Octavia spat, the disgusting gesture a testament to her anger. “They deserve more mercy than her! She’s tormented me, all because of something she does as well!”

Vinyl was starting to seeth inside at Octavia’s disparaging remarks. “Octy, you’re being bucking retarded,” she said through clenched teeth, her eyes a pair of slitted magenta daggers. “This thing is way more complicated than you know.”

“What else is there to know?”Octavia shot back scornfully. She could feel tears of anger, or so she told herself, in the corners of her eyes. “Who cares if she’s hurt? She deserves every bit of pain she gets for what she did!” If Octavia’s eyes had been flamethrowers, Vinyl would be a pile of cinders. “You’re the one who went after that bitch. Why in Tartarus would you waste time doing that if you weren’t going to do something useful and show her how much it can hurt! Just what gives you the right to─”

"You, know what? Just shut the hell up!”

Vinyl said it with such force that Octavia was taken aback. She stopped talking, her shock at Vinyl’s outburst silencing the proper mare. “You’re hurt, I get that, but you’re not thinking! She hurt you, but have you even stopped to think? To think that maybe, just maybe, you don’t know the whole situation? Dammit!” Vinyl stamped her hoof with enough force to rattle the pictures on the walls. “You don’t give a damn about that other mare and how much pain she already has inside her! You know what I saw when I went to her house? A poor, defenseless little foal! She was all huddled up like a little filly, suckling a pacifier, wearing a big diaper, and cuddling her teddy bear, all because she felt like she was about to be betrayed to the world and be laughed at and humiliated! You really think you’re the only victim here?! You may have had it rough, Octy, but Lyra has had just as much pain and stuff as you have, and I’ll be damned if you’re going to sit here and lecture me about how much she hurt you! You both hurt each other, and it’s time for both of you to get the hell over it!”

When the rant was over, Octavia’s jaw was slack. In all the years she’d know Vinyl, she’d never, ever heard her go off like that. Every time somepony insulted her or did something to her, she’d shrug it off and claim it was nothing, even if it did cut her. Her laid back attitude on life usually meant that she was unflappable. But this… this was a side Octavia had never seen before, and it was a bit frightening.

Across the room Vinyl was breathing heavily, each breath she took ragged. Her eyes were red-rimmed, her cheeks stained with tears that had dripped down and hit the carpet, and her legs were trembling. In her head, things were reeling. She just couldn’t believe Octavia was being this way about Lyra. All those years of pain were real, yeah, but she had just come from Lyra’s house and seen the poor mare at her worst. Seeing her like that reminded Vinyl of Octavia somehow. Maybe it was the diaper, or the pacifier. Maybe it was how Lyra just needed somepony to baby her and make her feel loved. But whatever it was, seeing Octavia talk about Lyra like that had triggered something primal, and it had made her snap. She wanted to defend Lyra, just like she wanted to defend Octavia, though she didn’t quite know why she wanted to do that, either. Mothering instincts, perhaps? She didn’t know. All she knew was that she was looking across the room at a now frightened Octavia, and she wanted her so badly to be friends with Lyra and heal their hearts.

She sniffled as she said, “I know you’re hurt, Octy… but you gotta make up with Lyra. Please. She’s been through too much pain already for you to add more hurt to the pile. And I don’t want to see you being so...so hateful. You’re an awesome pony, Octy, and you’re way better than hating somepony like this.”

Octavia blinked, staring at her friend, the pony she had called ‘Mama’ only this morning. “I...I…” She sniffled, suddenly overcome by her emotions. She didn’t know what to do.

Trotting up, Vinyl gently wiped Octavia’s eyes. “Shhh,” she cooed. “I’m not mad at you, Octy, I promise. Don’t cry.” She rubbed Octavia’s back, easing her big foal down onto the bed. “Why don’t we get you all padded up, huh? Nice and safe for mama.” Octavia sniffled, then nodded. With a quick little peck on the cheek, Vinyl walked over to the closet and pulled out one of Octavia’s diapers, then she began to pad up her big filly.

Out in the living room, Lyra was shaking. She was still trepidatious after the incident at the adult foal store, and hearing the shouting match down the hall had sent her mind into a frenzy. She wasn’t in any state of mind to hear that kind of fighting, and she’d almost bolted out the door, never to see either Vinyl or Octavia ever again. It was only the promise she’d made to Vinyl that kept her sitting on the couch. Frankly, it was only by the barest shreds of willpower that she kept the couch unstained.

Vinyl emerged from the room, closing the door with a quiet click. The apartment was silent, save for the gentle hoofsteps Lyra heard coming down the hall. She turned and looked at Vinyl nervously.

Vinyl didn’t say anything as she approached. She just patted the big couch, reaching over to guide Lyra until the nervous mare was laid down. She wore a look of concern on her face, mixed with fear that Octavia would randomly walk in and see her laying on the sofa. But the calm, almost motherly look on Vinyl’s face reassured her. As she laid there, Vinyl unfolded one of the diapers that she brought back from Lyra’s house, then she levitated Lyra’s back legs so she could slip it under her. Lowering her gingerly into the fresh padding, she got out a tube of rash cream and started to spread it on Lyra’s flanks and nethers. Then she shook foal powder on her diaper area, its sweet aroma helping to calm Lyra’s frazzled nerves, and finally Vinyl lifted up the front and held it to Lyra’s stomach while she gently taped it in place.

Pulling Lyra up, Vinyl took her by the hoof and lead her towards Octavia’s room. The diapered mare whimpered, biting her lip. She wished she had her binky to make her feel better. Each waddling step was a step closer to...she didn’t know. Something big, probably disastrous. The only consolation she had was the thick, poofy diaper she wore. Each crinkle it made was both reassuring and worrying.

“Now, don’t overreact,” Vinyl said, her voice slightly too loud to be talking to Lyra. She held the trembling unicorn up as she reached out to gently push the door open.

The door swung open. Lyra and Octavia both went completely still, staring at each other. Sitting on her bed, her padded plot beneath her, Octavia felt curiously breathless. Her eyes slowly drifted across the mint unicorn as they both struggled to comprehend what they were seeing. The very first thing about Lyra that Octavia noticed was how big it was. The diaper was thicker than any she owned.

Lyra was as stunned as Octavia. It was one thing to hear about it, and to see Octavia at the adult foal store. Seeing the prissy pony diapered, sitting there with eyes as wide and scared as her own must look, Lyra found so much from the last few years just...drop away. It was an oddly liberating feeling. Vinyl had explained how it was a misunderstanding, but somewhere inside Lyra hadn’t believed her. After seeing the slate gray mare, with her carefully brushed ─ though now half-disheveled ─ mane and posh pink bow tie, sitting on the bed wearing a big, foalish diaper, Lyra started to consider that what Vinyl had said about Octavia was true.

Nopony said anything for a long while.

“Will one of you say something?” said Vinyl.

Gulping, Lyra tried to speak. It was hard, but she managed to stutter out, “T-they...they were m-my...diapers…” she shuffled her hooves, staring at the ground.

Octavia said nothing, staring at the pony she had hated and resented for years. Her first instinct was to deny it. They had to have been her diapers Lyra had found…except…she thought back, trying to remember. Had her own package been opened when she wore them in an attempt to find solace, later that night? She couldn’t remember.

“I-I’m s-sorry, I w-was so afraid you hated m-me, a-and when we met again, I...I was afraid…” Lyra sniffled as her voice cracked, her eyes wet. She trembled, refusing to look up, shame in her voice.

“Look, Lyra…” Octavia tried to work out what to say. “All those years, I was wrong about you. I thought you acted that way because you found my diapers and were making fun of me. It really hurt me, and I wanted you to feel nothing but pain. I… had no idea you were going through all that.”

Lyra was finding it difficult to respond to the confession. Like Vinyl’s assertion that Octavia wore diapers, the idea that she was hurt unintentionally made her feel awful inside. “I-I’m so sorry, Octavia. I didn’t have any idea you felt that bad, and if I had I would have tried hard to make it up to you. I… I thought for sure you hated my guts, and I-I was so af-fraid that you’d make fun of m-me and then tell everypony.”

Octavia’s eyes started to well up, matching Lyra’s. She swallowed to force the lump in her throat to go away. “I should be the one apologizing to you, Lyra. For hating you so much and wishing so much pain on you. I had no right to do that, not after what you’ve been through, and I’ll do anything to make it up to you.”

Lyra’s lips curled up slightly. “Y-you… you really mean that?”

Octavia nodded with a grin.

“Oh, Octavia…” Lyra’s voice broke down as she galloped up to Octavia and embraced her. For a moment, Octavia didn’t respond, but then she smiled and wrapped her forelegs around Lyra, happiness dripping down her cheek and into Lyra’s hair.

Vinyl sat back, watching the pair of foals hug, and grinned wide.

Chapter 3

Octavia retreated to the living room, leaving Vinyl to clean the remains of dinner away. The unicorn smiled, knowing her friend was going to be fretting out her need to pee and thinking about how to stop it. Of course, she was just going to overthink it and wet herself anyway. Thinking about peeing was not a smart way to hold in the need to pee.

Vinyl started to hum something without giving it much thought, certain she was going to win. Technically Octy was going to lose, but in the end she would see it as a win as well.  That was something Vinyl was certain of.

Finishing with the clean up quickly Vinyl peeked in on Octavia. The earth pony was sitting on the blanket, her hooves crossed and a frown on her face as she concentrated. Vinyl chuckled and came out, trotting over to her friend.

“Havin’ fun Octy?” She asked with a wicked smirk. The classical musician shot her a dagger-like glare in response. “I’ll take that as a ‘no’. Which means I need to improve your mood!”

“No, Vinyl, that really isn’t- mmphf!” Octavia let out a muffled squeak when her pacifier was shoved back into her mouth mid-sentence. She huffed. That had been what, the third time so far? It was getting beyond a joke, although Vinyl Scratch clearly disagreed.

“See, a ‘no’! Am I right, or am I right?” The DJ giggled to herself at Octavia’s expression. “The answer is that I am, by the way.”

Octavia’s response was muffled but Vinyl was fairly certain she got the gist of it from the tone. The sour look was driving Vinyl to laughter again as her friend struggled to get the pacifier out, only to constantly encounter resistance from the unicorn’s neon-blue magic.

Too busy laughing Vinyl didn’t notice Octavia suddenly change focus. The earth pony jumped at Vinyl, bowling her over. Before she could do anything a pair of grey hooves began to run down the sides of her belly, where she was most ticklish.

Now Octavia was the one smiling, even if Vinyl was still laughing. It was unwilling laughter so Octavia decided it was in her favor.

“Mmph mmhmm phmm.” She said authoritatively. It lost something thanks to the pacifier.

“Ahahaha-st-aha-sto-ha-oop!” Vinyl laughed as she tried to get out, hooves flailing. She was too distracted by the tickling to be able to focus her magic on lifting Octavia off so she was left trying to push her off.

“Mm hmfph?” Octavia ‘asked’. Translation: ‘you give?’

Vinyl continued to struggle. “Ne-hehe-var-ahahaha!”

With a muffled smirk Octavia resumed her tickling. Tormenting Vinyl was turning out to be nearly as fun as playing foal could be.

Despite her best efforts Octavia couldn’t manage to stop Vinyl from slowly turning over, although she could keep tickling her. It became harder and soon the DJ was pressing her belly against the floor, mane hiding her face and letting muffled giggles into the carpet. It made it a little less fun for Octavia to not see VInyl’s face as she was forced to laugh. Eventually she began to slow down the tickling, giving her friend some chance to compose herself. Not that Vinyl would, of course.

It was about to be a little less fun, or a lot more fun depending on your point of view, since she couldn’t see the glow of Vinyl’s horn through her mane and the feather slowly floating through the air behind Octavia. Vinyl’s smirk was hidden. She was so glad that she kept those feathers. Sure, Octavia thought it was disgusting but if that pegasus chose to fly into one of their windows Vinyl wanted something out of it. There were few pillows like pegasus-down pillows.

The small feather stroked Octavia’s thick diaper, brushing against her tail. The mare didn’t notice, at least not until it was between her and Vinyl.

“Surprise.”

Octavia blinked at the word her friend said for a second. What did she mean ‘surpri-

The diapered mare nearly had a heartattack when the feather began to tickle her. The tables were turned and she began to retreat, her forced laughter muffled by the pacifier filling her mouth. The feather followed her, eventually bringing Octavia down when she tried to cross over the play-blanket. She clutched her hooves in, feeling the light pressure on her bladder grow.

“Hm gffmph!” She cried through her pacifier, her offering of ‘I give’ lost.

“That could have been a ‘give’, I guess.” Vinyl said lazily as her magic continued to tickle Octavia. “But...I’m not quite sure. If a certain prissy pony agreed to let me choose a onesie for her to wear I might agree that it was.”

Nodding through her shaking and squirming Octavia didn’t have much choice. It was too her great relief that the feather floated away. Panting, Octavia thanked her years of self-control for the fact she hadn’t soaked her diaper. She only vaguely noticed Vinyl trotting off, whistling some cheerfully smug little tune.

Eventually Octavia turned over, slowly pushing herself up. She took a deep breath through her pacifier, absently sucking on it without thinking. It was comforting and calming after the tickle torture from her so-called friend.

Like her name had summoned her, that so-called friend came bounding down to her with a wide grin and something floating behind her. It took Octavia not long to realise what it was that came floating along and her cheeks went red.

‘Of course she found it, she must have seen it when she broke into my chest.’ She thought with a sigh as she looked over the onesie. It was purple to match her cutie mark, its rear heavily frilly directly over where her diaper would be covered from front to back. The frills on the bottom were the same white as the lace on the hems of the very short, very puffy ball like sleeves that would sit just as much if not more on her shoulders than on her forelegs and the double rows of lace that highlight the bib portion on the chest. Proudly emblazoned on the bib part of the onesie were the word’s “Mommy’s Little Musician”.

Looking at her widely grinning friend Octavia died a little on the inside from embarrassment. Another little bit inside was squealing like a filly on her birthday.

“Hooves up Octy.” Vinyl sang cheerfully. “Time to dress Mommy’s little musician in her cute little onesie. Come up, lift ‘em up.” Se prompted.

With a sigh Octavia complied. In the face of Vinyl resistance was futile. The onesie came down over her as fast as Vinyl could levitate it. It was as snug as ever when the button was sealed shut with a snap of the poppers hidden in the rows of frills.

Standing back to look at Octavia, Vinyl’s jaw fell open.

“....wow.” She said quietly. “Octy...you...are...ADORABLE!”

“Mmmph!” Octavia cried out as Vinyl glomped her, falling on her rear with the unicorn hugging her warmly.

“Sooooo cute!”

Vinyl normally only gushed over things that were loud and against sound pollutions laws. Yet here she was, hugging Octavia and squealing over her like she was the cutest thing Vinyl had ever laid eyes on.

“Vmmph hmm!” Octavia whined, but she didn’t struggle too much. She pretended not to notice her own forehooves slowly reaching up to return the hug.

They weren’t sure how long they lay on the checkered blanket among Octavia’s foal toys hugging, but it was at least ten minutes of them just curled up, hugging each other. They only stopped when a series of loud, sharp knocks at the door made both jump.

“Damn it!” Vinyl hissed, getting up. “Who is it?” She called out, only grinning a little when Octavia made a sound her pacifier turned into a whimper of disappointment.

“Somepony who wants to go home! Hurry up and answer the door!” A familiar, unwelcome voice snapped from outside.

The two mares shared a look. Lyra and Octavia did not get along. They at best tolerated each other for the sake of being able to do shows at the Royal Canterlot Theatre For Music & Arts. Vinyl wasn’t even sure why. Lyra was perfectly nice so long as it had nothing to do with Octavia and when Lyra was around Octavia mood just fell right through the floor.

“I’ll get it. Stay here, unless you want Auntie Lyra to see how cute you are.” Vinyl cooed with a giggle, getting a scathing glare in return.

Octavia didn’t have much choice. The hall between her and any room but the kitchen was straight down from the door so she would only have until Vinyl opened the door to get somewhere else. So long as Lyra didn’t come in she would be fine...

Although she was more annoyed at Vinyl calling her ‘Auntie Lyra’. As if that jumped little so and so could be anypony’s aunt.

“Stay cute, cutie.” Vinyl added before stepping out of the living room, into the stretch of empty hall a pony and a half long between the door and living room.

There was a grumpy unicorn on the other side of the door when Vinyl opened it. “Yo.” The DJ said, grinning to counteract the frown in front of her. “What brings y-”

“Here.” Lyra said, immediately shoving a long, thing item at her. “Octavia forgot her bowstring and I had to bring it halfway across the city.”

“Thanks.” Vinyl took it in her magic. Before Lyra could flee she added; “So why’d you get stuck with bringing this thing over? Couldn’t have waited until tomorrow?”

Lyra rolled her eyes. “Apparently not and I was the only pony there who knew where Octavia lives. Unfortunately.” She huffed, looking unhappy.

Looking over the top of her trademark glasses Vinyl shrugged. “Bad luck. Someday one of you is going to have to tell me why you both, who are pretty cool not to mention hot girls hate each other so much.”

“It has nothing to do with you, Scratch.” Lyra growled back. “And let me remind you, I have Bon Bon so cut it with the....” she trailed off, sniffing.

Vinyl waited a few seconds until losing what limited patience she had for mysteries. “Cut it with the....?” She repeated curiously.

“With...with the flirting, is that foal powder I smell?” Lyra asked suddenly, craning to look past Vinyl. She had an odd expression of curiosity mixed with....something Vinyl wasn’t quite sure of.

Fortunately for herself and for Octavia, Vinyl was good at lying. She didn’t try to subtly block Lyra’s view because she knew there was nothing to see. The smell of foal powder was lingering on her a bit from diapering Octy but she obviously wasn’t going to say that.

Instead Vinyl lifted her glasses with a hoof, giving Lyra a confused look. “Foal powder?” She asked skeptically, like the question was quite odd. “You all right there Heartstrings?”

“Huh? But I can smell...” Lyra looked confused, biting her lip uncertainly.

That was something Vinyl noticed. Lyra was a lot of things but she wasn’t uncertain. Like Octavia, Lyra was very good at being firm and certain although without the prissiness of a Canterlot mare.

Vinyl chuckled without warning. “So, I get it. Heh, follow it up with a line about how the place stinks of Octy! Like Octy is stupid like a foal. Nice.”

Lyra was taken by surprise by the assumption on Vinyl’s part and opened her mouth to correct her. Her mouth snapped shut before she could say anything and she nodded, a light blush on her face.

“Y-yeah, that was it. Not my best.” She said, trying to sound like she was admitting something unhappily.

The DJ shrugged it off. “It was fine, although you should have sprung the punchline before I ruined it. Since you brought her string I won’t even tell Octy about it.”

That reminded Lyra and she glanced past Vinyl at the empty hall again. “Is Octavia in? She should at least thank me for bringing it.” She said, focusing on scoring points against her rival and/or enemy. Octavia was so ‘proper’ she would have to thank her and would be reluctant the whole time, making it fun for Lyra.

It took Vinyl a second to come up with a lie. “Technically, she’s in. In the toilet that is.”

“Oh, I can wait.” It would be worth it. “...normally she would have had some comeback when I called out earlier.”

Vinyl tried not to frown. She really needed to get rid of Lyra so she could go back to playing with Octy. “Oh, she’s definitely in. She’s never been as in the toilet as she is right now.” That made Vinyl snicker to herself.

Lyra looked confused by the strange statement. It was quite strange. “What do you mean?”

In the living room Octavia was still sitting on the blanket and could hear them clearly. She had even stopped sucking on her pacifier and was breathing as quietly as she could. She almost began to sweat. Vinyl wasn’t going to tell her, was she?

Vinyl leaned in. “Let’s just say, if this place smelled of Octy you’d be able to tell. She’s not just in the toilet, she’s filling it. Octy is doing like the most mondo, ginormous, super sh-”

“That’s enough!” Lyra interrupted frantically. Close but hidden, Octavia was thinking the same thing with an outraged blush on her cheeks. Lyra waved her forehooves, looking a darker shade of green in the face than usual. “I’ll...I’ll get that thanks some other time.” She said.

Vinyl shrugged. “Your loss.” She said it with a wicked grin of amusement.

Watching the other unicorn run off Vinyl shut the door with a loud ‘click’. She had barely turned around before she found a diapered mare in front of her, sternly lecturing her in a series of ‘mhm’, ‘mph’, ‘gffmp’ and ‘pffb’s.

Letting Octavia get it out of her system Vinyl waited nearly a minute before getting bored.

“Bored now. Come on cutie, turn around so mama Scratch can check that diaper of yours.” She cheerfully spun Octavia around, surprising the earth pony long enough for Vinyl to unpop one of the poppers and test the diaper before doing it back up.

“Gmph!” Hearing Vinyl call herself ‘mama’ made Octavia blush.

“Aww, Octy is still dry. I’m so proud of you, keeping your diaper clean for so long.” Vinyl cooed in the most patronizing voice she could manage, reaching over to ruffle Octavia’s mane. Her hoof was batted away and a pout formed on Octavia’s face.

The diapered classical musician stomped one of her front hooves like a foal throwing a tantrum. She didn’t notice that, too busy being indignant.

Enduring another withering lecture of muffled sounds Vinyl managed to hold on for just over a minute before giving in.

“Bored. Let’s play! Come on lil’ Octy, time ta play with mommy!” She giggled like a foal herself as she dragged Octavia back to the blanket and toys.

Octavia dug her hooves in. “Mmm!” She whined, tapping her pacifier.

Vinyl pretended not to get it. “What was that? Sorry Octy, your mommy don’t speak foal.” She said.

‘She doesn’t speak Equestrian properly either. That don’t should have been doesn’t.’ Octavia thought with a roll of her eyes. “Mmhph!” She whined again, tapping the pacifier. “Nmn mm mmm mmhmmy.”

“Fine fine.” Vinyl pulled the pacifier out with her magic, grinning as Octavia moved her tongue and mouth for a few seconds to get them used to freedom again. “That better?”

“Don’t talk to me like I’m a foal.” Octavia said, glaring at her supposed friend. “What were you doing? Lyra is going to be unbearable next time I see her.”

Vinyl held up a hoof, trying to calm her down. “Whoa, what did you want me to do? Tell her you were sitting in the living room in your diaper?” She asked.

Octavia hesitated. “Well, no...” She said slowly.

“So I made something up and then I got rid of her. Interruptions are annoying.” Vinyl went on. She sighed. “I was really enjoying that snuggle too.”

That made Octavia blush. “Oh, uh, I guess I did too.” She admitted quietly. “It was...nice.”

Vinyl threw a hoof over her shoulder. “See? Told you this would be good. Now let’s play a game. Any games you want to play Octy?”

The musician rolled her eyes. “You don’t have to make yourself do this for me, Vinyl. What we’ve done so far has been more than enough.”

Gleefully ignoring Octavia, Vinyl decided on a game. “I know what we can play. Its perfect for a cute little foal like you Octy. Let’s play peekaboo!”

Octavia blushed, shaking her head. “Now Viny, you really must stop-”

“Where’s mommy gone?” Vinyl cut her off, using a dry washcloth she pulled from kitchen with her magic to block Octavia’s sight.

“Gah!”

The cloth came off. “Here she is!” Vinyl said, laughing at Octy’s pout. “Aww, what’s wrong? Disappointed you couldn’t find mommy?”

“No, Vin-” A pacifier cut Octavia off. It took her a bit to realise it wasn’t the same huge one as before. This one didn’t expand in her mouth so she couldn’t talk. She wasn’t even sure how Vinyl got the other to do that. “Shewioushwee.” She lisped through. it.

“Shush now Octy, mommy is talking.” Vinyl ordered casually. She was only half surprised when Octavia actually fell silent. “Good girl. Octy gets a treat for being a good girl. After you’ve filled your diaper all nice and full I’ll read you a bedtime story.”

“Oh ooy.” Octavia tried to sarcastically utter ‘oh joy’ but the pacifier took some of the impact out. She suckled on it sourly. Just because it ruined her attempts at sarcasm was no reason to waste a perfectly good pacifier.

Vinyl laughed, hearing the sarcasm anyway. She knew Octavia very well. But right now she was more interested in cute little Octy. Her friend wanted the chance to be foalish and just relax but her own innate prudishness and embarrassment was holding her back even though it had been made perfectly clear Vinyl was fine with it.

“All right, let’s play something else instead. Hide and seek, like peekaboo but for big girls.” Vinyl giggled to herself. “So let’s just pretend little filly Octy can play too. You can even hide first.”

Octavia didn’t budge, pouting behind her pacifier. She didn’t want to play hide and se-

“If you don’t hide, I’ll catch you right away. And if I do that I’ll have to tickle you again.” Vinyl added, smirking as Octavia bolted from the room. “You’re meant to wait until I start counting, you silly filly!” She called out, laughing.

There weren’t many places to hide in their small apartment but Octavia did her best. Her room was the room she knew best and the logical place to hide. But Vinyl knew that. Since it was logical Octavia almost went in anyway. Logic wasn’t always Vinyl’s strong suit.

But instead she crept into Vinyl’s room. She justified it, since she hadn’t paid Vinyl back for sneaking into her room. The room was dark, its curtains almost always shut, and just as much a mess as ever. Closing the door quietly after her Octavia let her eyes adjust to the darkness. A few random things with neon glows to them gave her a little bit of light, and so did a lava lamp. Shifting through the mess she began to look for somewhere to hide.

The closet was right out, and there was nothing embarrassing in there. Nothing embarrassing to Vinyl, at least, as Octavia went bright red when something long, plastic and hard nearly fell on her when she tried to move a few things aside to see if there was room.

The sound of hoof steps outside suddenly cut off her time to hide and Octavia looked around. She didn’t even notice how much she had gotten into the game now. As quietly as she could Octavia began to wriggle under the bed. The covers were already half off, on the same side she was on, so she pushed them up.

It took too long for her comfort to get under and she felt her diaper catch on the edge of the bed frame. It was way too big to fit under and just that made her blush. With a bit of work she managed to get the covers back cover her rear at least., feeling the edge over her hooves. The way they had been spilling off the bed it was impossible to notice the difference.

When Vinyl trotted into her room she was pretty much blind. Octavia hadn’t been in her own room so Vinyl decided she must be in hers. It took her about a minute to remember her glasses and take them off, the light dulling from the purple tint making it impossible to see. With them off it was much easier.

It still left her room very dark. Looking around though it wasn’t hard to find Octy. Her frilly-butted onesie and her thickly padded rear poked out from under the bed. A stray piece of clothing from the mess covered her hooves and noticing the way her bed cover had been left Vinyl guessed Octy thought they were covering all of her thanks to the cloth over her hooves.

Holding in giggles Vinyl considered the sight. It was absolutely adorable, especially because it almost looked like a foal who thought that she was hidden because she couldn’t see others. Just as she was about to say something an idea presented itself. Again she had to fight back laughter.

Vinyl turned and left, pretending she hadn’t seen Octavia. She hurried to her friend’s room and the waiting chest of foalish clothing. She opened it and began to levitate things out. Let Octy ‘hide’ a little longer. Vinyl could just fix her wardrobe.

She didn’t remove anything but the onesies were placed in the large walk-in closet at the very front of the racks. Unfortunately there weren’t any foal dresses to go up and look hilarious next to the fancy ones Octavia had for formal events. Hopefully she could convince Octy to get some more appropriately foalish dresses to go in. The small chest of draws in the room found its content moved to fit Octavia’s diapers. The chest of drawers wasn’t used much so it was easy and Vinyl was pleased with how the diapers, cloth and disposable, all fit in the drawers, nearly perfectly filling them up. The rest of the spare spaced was used by the palstic pants.

A single drawer was left at the top and in there Vinyl stacked Octy’s bibs and a bunch of other random things. There were little fabric hoof-mittens among other things and even bonnts and bows. There was a bonnet that matched Octy’s current onesie she had somehow missed before too.

“Vinyl!” She whined through her pacifier. “Wha’ awe wo doin’?” She demanded.

“Oh, Octy! Perfect timing. I saw your cute little diapered butt sticking out from under my bed and thought I’d leave you there for a bit. Your wardrobe needed to be organised and you left these drawers empty. So I filled them!” She grinned. “I filled them with your diapers.”

Ignoring the part about her ‘cute little diapered butt’ Octavia looked in her drawers. With a sigh she pushed it back in.

“Wha’ now?” She asked, deciding the game was over. Her clock said it was 8:39pm. Only just over an hour to go.

Vinyl seemed to have an answer, since she pulled Octavia out. “I think you can play a bit. I need to dig something out of my stuff. Blocks. You can play with blocks.”

Leaving her in the living room with her blocks, Vinyl retreated to her room. It was odd and random, but so was Vinyl. Still, left to her own devices Octavia stared at the blocks. They had big primary colour letters on them or things like a star or heart. Glancing at Vinyl’s door she reached for them and slowly began to amuse herself, stacking them. At one point she spelled out ‘diaper’ in a tower, for her own amusement. The sophisticated mare giggled at her blocks and promptly knocked the tower down.

Watching from the crack she had left between door and door frame Vinyl pressed a hoof against her muzzle. Octy looked so cute when she thought she was alone. Settling down, Vinyl watched her friend playing gleefully like a foal.

Half an hour later Vinyl yawned, growing tired. Octy had moved on from her blocks to the soft toys that had been brought out for her. She was making one of them pretend to play an instrument. After a minute she put it down and made another one do something that looked to Vinyl very much like how she looked when DJing.

She emerged at last, smiling as Octy dropped the doll and Octavia  blushed.

“Having fun?” The unicorn trotted past her friend, heading to the kitchen.

“Y-yes.” Octavia agreed reluctantly, dropping her pacifier. A minute later Vinyl was back, a drink of something sweet and fizzy in her magical grip.

“So.” Vinyl took a swig of her drink. “You’ve never said, but why do you and Lyra hate each other so much? You’ve never told me before.”

Octavia stared at the ground when she heard the question. She hadn’t told Vinyl, or anypony else for that matter. The main reason was wrapped firmly around her waiting to be soaked. But Vinyl knew so why not?

“I suppose I might as well tell you.” Octavia agreed reluctantly. She was used to keeping it a secret. “I never told anypony before now because it involved this.” She indicated her diaper and onesie.

Vinyl looked surprised at the news. “Really? What happened?” She was even more eager to know now.

“Not much. Okay, that isn’t quite true. You know that I shared a room with Lyra at college, right?” Getting a nod in answer Octavia sighed. “Well, I had just bought my first diaper. Finally got brave enough for it.”

“When you had a roommate who you shared an actual room with? Brave.” Vinyl wolf-whistled.

Octavia flushed and shook her head. “No Vinyl, not brave. Stupid. If I hadn’t Lyra would never have...” She sighed.

Octavia nodded. “I travelled to the other side of the city to get them when she was away for a few days and the day after she got back she found it anyway. I got back from a class earlty to find her with one of them. She was staring at it when I came in. Since I had hidden the packet in my private area-”

“Private area?” Despite the importance of the story Vinyl couldn’t help interrupt with a snicker.

Catching the euphemism Octavia went red. “Shut up. We each had our own things in areas the other wasn’t allowed to go into, under any circumstances. My diapers were in the back of there, hidden behind everything. When I realised she had found out, and that she had gone through my things like that I just...I saw red. We screamed at each other, I’m not sure what I screamed or she did, and I stormed off. I think she did too.” Octavia shrugged. “All I know is that by the time she came back from staying at a friend’s home I had moved all my stuff out and found another room. We never talked. When we ran into each other here...”

“Awkward.” Vinyl suggested.

“Very. Since then we just sort of start to snipe at each other all the time and things are how they are now. I don’t know what she thought it was or whatever, but we’ve just been automatically hostile to each other. She’s never mentioned it and I never brought it up.”

Vinyl suddenly wrapped her in a hug. “Well, just because Lyra was a bitch doesn’t mean nothing.”

“Doesn’t mean anything.” Octavia corrected automatically.

“Exactly! Now, turn that frown upside down. I’ll find you something to play with.” She turned and began to rummage.

She sat back down on the blanket, hearing her plastic pants crinkle and her weight falling on her thick padding. Looking down at her onesie she ran a hoof across the lace-trimmed bib, playing with it idly. Despite all her work at being grumpy the thrill of being in front of another pony in her foal clothes and diaper was making her heart beat with excitement. It was just so much better with somepony else involved.

“V-Vinyl...” She squeaked, looking nervous. Her friend was looking through the toys for something she could get Octavia to play with but looked up.

“Yeah?”

Still playing with her onesie Octavia didn’t look up. “Uh, you called yourself my....my mommy...”

Realising what was wrong Vinyl went a little red too. “Well, I kinda thought it worked. If you’d rather I keep things a bit less-”

“No!” Octavia said it before she realised what she was doing and blushed at the surprised look on Vinyl’s face. “No.” She repeated, going back to looking nervous. “I was wondering...when you said it, did you mean you want to...”

Watching Octavia trail off nervously, Vinyl smiled suddenly. now she got it. “Octy, are you asking if I’ll be your mommy?” She asked with odd gentleness.

Octavia looked at the floor shyly. “M-maybe. I know its strange. It might be a little much, I can understand that. I just had little fantasies of having, well, having somepony to do that for me while I was dressed up like this.”

“I can’t.”

Vinyl’s words were almost like being punched and Octavia slumped, sniffing slightly “Oh...oka-”

“Its two minutes until ten and your diaper is still dry.” Vinyl interrupted her, putting her hoof under Octavia’s chin and making her look up. “I can’t be Octavia’s mommy, because she can hold it in like a big girl. Little Octy, who soaks her big snuggly diapees for mommy on the other hoof...”

Octavia caught on and stared at Vinyl. She gulped. “R-really? Do you really mean that?”

Vinyl nodded. “I do. But once little Octy has wet her diaper, she has to follow the rules. Mommy is in charge and foals do what their mommy says. Its your choice.”

The clock was counting down the last minute until ten. Octavia looked at it as the seconds fell away. She could just hold it in for another minute and she would be home and dry, literally. Vinyl would stop bothering her about wearing her diapers more and would be her slave for a week. Everything could continue on as it had before. Octavia would rehearse during the day or practice at home on her own. She would spend most nights in relaxing with a book, occasionally being dragged out by Vinyl to some dive. She would continue her (mostly) peaceful, normal life.

Or she could just let it go and soak the thick cloth diaper wrapping her rear in warmth and secruity. She could fill it up like a foal without a smidgen of control and her home life would be spent in a bulging diaper. Octavia would come home and the first thing to happen would be her rear being powdered and diapered. She would lounge around in just her diaper or sometimes a onesie or romper. nursing a pacifier. Vinyl would coo at her and change her when she went wetsy like a helpless foal. Instead of a book she would be left with rattles, blocks and dolls to amuse herself. Life would change drastically for her and her roommate. Her best friend would still be her best friend but she would also be her mommy. She would have a mommy who wanted to spoil her and play with her.

Twenty seconds to go and Vinyl was getting nervous now. Octavia was wearing her thinking expression, furrowed concentrated. The DJ wasn’t exactly looking forward to a week as Octavia’s slave. Even worse, Octavia might withdraw all her fun Adult Foal back to her room and uncrack her shell. That would be....

Vinyl’s thoughts trailed off. She could hear something, a faint hiss. Looking at Octavia’s expression Vinyl’s eyes wandered down and while the onesie hid the diaper the way her friend was sitting on it had changed as she unleashed a massively full bladder. Octavia wasn’t wearing her thinking expression after all.

Octy was wearing her wetting face.

The large supply of urine released, Octavia looked at Vinyl again. Timidly, her face now faintly embarrassed but her eyes hopefully, Octy began “M-mommy....”

Vinyl smiled reassuringly at her. “Go on, mommy is listening.” She said back with barely contained glee.

The words were so strange to hear actually coming out of her mouth. Octavia had imagined saying them before, her voice meek and childish, but had never done it even in the privacy of her own room. Now she was and with the hand of the clock ticking on past ten pm she couldn’t bring herself to regret it.

“...I made a wetsy.”

Taking Octavia by the hoof Vinyl stood her up. “That’s what I thought.” With that she led her overgrown foal off to change her soaking diaper, the prim and proper classical mare waddled after her.

Several blocks away Lyra sat on her bed, staring down at something. Her small apartment wasn’t as far away as she had claimed and she had been home for a while. In the time since her visit to return Octavia’s bow she had spent most of it just sitting there...staring. Bon Bon lived in Ponyville and only had time to visit Canterlot on weekends, or Lyra visited her, so unlike those two she had an apartment to herself. Somewhat small but it was enough for her.

Lyra licked her lips which had gotten dry from her nervousness. The smell. She was certain she had smelled foal powder. It was unmistakable. But maybe she had just imagined it. Just memories of back then, of how Octavia had hurt her despite supposedly being her ‘friend’ when she found out Lyra's secret. That was all. Memories playing up and tricking her senses.

She continued to stare. She couldn’t look away. The temptation nagged at her like it always did. When she happened to get a smell of foal powder, most of the time she just ignored it. But smelling it so clearly in such an unexpected place made it hard to ignore. Nearly impossible.

Nearly trembling, Lyra tried to tear her eyes off it. The forbidden fruit. She had to fight it. However much she enjoyed it, she had to. For Bonnie’s sake. Sweet Celestia, what if Bonnie found out? She couldn’t take that risk. Not ever. The mare she loved would think she was a freak. She just knew she would. Lyra already thought she was a freak herself.

Thinking of her wonderful marefriend Lyra closed the small chest, locking it tight and hiding the key. The chest followed and she did her best to put all thoughts of it from her mind.

She didn’t do a very good job at any of those things except thinking about Bon Bon.
