The Right Moment

The Right Moment

Rainbow Dash began to stir under her covers as the morning sunlight came through her bedroom's east window. Greeting the morning with a reluctant groan, she threw the covers off of her. She was never much of a morning pony, but when she stretched, and heard the crinkle sound come from the diaper in between her legs, suddenly the morning didn't seem so bad.

She swung her back legs over and hopped out of bed, her disposable diaper crinkling with her every step. She walked to her dresser and smiled at herself in the mirror. Rainbow Dash the weather pony. Rainbow Dash the daredevil.

Rainbow Dash the adult foal.

She had been like this ever since she could remember. She assumed she had always had a completely normal foalhood, but not too long since she was out of diapers, she wanted right back into them. Of course, this was something she had kept from her parents. Growing fillies were supposed to want to, well, grow up.

Not her.

Her greatest fantasy was to not have a care in the world. She dreamed of asking her parents to put her in diapers, becoming their baby again. She fantasized about being a bedwetter, and her mom and dad having no choice but to make her wear at night. Those fantasies never came to pass, because as much of a daredevil as she had become, she never had the guts to mention any part of this to her parents. She had spent her fillyhood keeping these innermost desires under wraps. So when she had turned 18, moved down to Ponyville and got a job, she finally had the opportunity to indulge.

But she still felt alone.

This had been her secret life for years. None of her closest friends had any idea she did this. Everything having to do with this fetish was confined to her top dresser drawer, which she kept locked at all times. She knew she wasn't alone in this; the store she got her items from served enough with this kink to keep a steady supply. Still, most adult foals kept this side of themselves from all but the very closest and trustworthy of friends.

Rainbow felt that even her five friends didn't quite fit those requirements. All but one.

She was amazed that she had been able to sleep last night, wondering how Applejack was going to react to her sharing this secret with her. The two of them had been seeing each other for just over six months, and Rainbow finally decided that she didn't want there to be any secrets between them. So she had decided that the time had come. Last night she invited Applejack to come up to her house after work this afternoon, because she had something to show her.

After about a minute of standing in front of her mirror, she felt the morning call of nature come to her bladder. Since she only wore for short amount of times, she still had to concentrate a bit to let her mind know that it was okay to go when she had a diaper on. She exhaled and relaxed her nether regions, and a trickle of urine quickly turned into a full stream, trapped by the diaper. The spreading warmth between her legs was euphoric. So far, nothing else had brought her closer to foalhood than that. After about twenty seconds, the stream died down, and the wet feeling slowly faded as it was swallowed by the padding. The warmth remained, and Rainbow jumped back in bed to enjoy the squishy crinkling sounds of the now considerably thicker diaper.

She wiggled around for a few minutes, feeling down there every now and then, waiting for the warmth to fade away, at which time she ripped the tapes off from the sides, and promptly threw the used garment in the trash can. After a quick shower, Rainbow took the trash bag and dropped it off in the closest dumpster on the ground when she left for work.

Work; the one thing she was hoping would help calm her nerves for the day.

Applejack wasn't sure what Rainbow had in store for her up in her house tonight, but she was likely going to find out in a few minutes. Rather than have Rainbow fly her up there like she normally did, she figured she'd surprise her marefriend a little early by getting there before she got home from work. Without some pegassistance, there was really only one way to do that. Coming up to the front door of Golden Oaks Library, she gave a few knocks, and Twilight was there to greet her in a matter of seconds.

“Oh hey, AJ. Balloon's around back. Listen, are you sure you know what you're doing?”

“If I can lasso Rainbow from the top of the thing in midair, I'm sure I can handle flying it. I've flown one in my time, so don't you fret. I'll have it back tomorrow morning, not a scratch on it.”

Twilight gave her a smile, and pointed her around back, where her weather balloon was waiting. It was enchanted, so there was no gases. Just a matter of pulling on the right rope to control altitude and direction. Once Applejack got the thing airborne, she was glad that Rainbow's cloud house wasn't too far away.

Ironically, Rainbow's house of clouds was actually some of the lowest hanging clouds in the sky. As she got closer, Applejack knew to slow down and take things nice and easy. The last thing she wanted of this early surprise was explaining how she damaged a part of her home. So slowly she went, barely tugging on the forward rope, once she got to the right altitude. Over the course of two minutes, she neatly situated the basket just to the right of the front door.

Her parking job complete, Applejack reached into her saddlebag and came out with a glass bottle containing a glowing blue potion, Twilight's other, more frequent favor. She popped the cork and downed the contents in three swallows. With a small burp, she opened the door of the basket and tenderly reached out to test the results of Twilight's cloud-walking potion. Her hoof met firm but poofy resistance, and pushing against it a few times was good enough for her. As she stepped completely out of the basket, she heard the approaching sound of flapping wings.

“Well ain't this a surprise.” Rainbow Dash called out as she made the final approach to her front door. When she touched down, Applejack gave her a smile and a hug.

“Thought I'd surprise you, and now you don't have to carry me up here. So what is it you have to show me?” Applejack asked as she broke the embrace.

“Well, um... Ya see, there's no delicate way to put it.” Rainbow said as she opened up the front door, inviting Applejack into the foyer. She went up the stairs to her bedroom, Applejack on her heels. Opening her door, Rainbow Dash went over to her dresser drawer. Her cheeks had a tint of red in them by now.

She began to twist the dial of a small combination lock on the top drawer. AJ had been in her room many times, and that lock had always been there. She just paid it no mind. So suffice to say, her curiosity was peaked now. Rainbow turned it for the third time, and the tumbler gave way.

“A few days ago, you said you didn't want there to be any secrets between us, so...”

With that, Rainbow lifted the lock, set it on the top of the dresser, and stepped aside. Applejack gave her a curious look, but nevertheless stepped forward. She placed a hoof underneath the drawer, and pulled out towards her, hoping this wasn't some elaborate prank that Rainbow had been planning.

Taking her first look inside, she didn't quite know what to think. There were a dozen diapers, a container of foal powder, and a foal bottle. The diapers looked big, like they were...

...For a grown pony.

Applejack glanced over at Rainbow, who was shaking with nervousness.

“Rainbow, what is this stuff?”

Rainbow swallowed hard, trying to bring the words to her mouth.

“W-well, I just... Just... Like to wear them. It makes me feel like a foal again.”

Applejack glanced back at the contents of the dresser. The front of the diapers had a graphic of a blue sky heavy with clouds. She really didn't know what to say about all this. About ten seconds passed before the silence was broken with Rainbow's hoofsteps as she quickly came towards the dresser.

“Sorry. I'm really sorry, just... Just forget I said anything.” Rainbow stammered, quickly closing the drawer and replacing the lock before making a full-on gallop for her bedroom window.

“Rainbow, wait!”Applejack called, finally snapping out of her stupor. It was too late though. If Rainbow heard her, she wasn't deviating from her flight up and away from her house.

The farmer stood in her marefriend's room for another minute, before she decided to do the rest of her thinking on the ground. She got in the weather balloon, checking to make sure the door was locked, and began her descent from the now-vacant house, wondering what in Equestria had just transpired.

Applejack Investigates

As hard as she tried, Applejack was having difficulty grasping the fact that her marefriend, the most brash and egotistical pony in town, had a side to her that wanted nothing more than to be treated like a foal.

She had, of course, gone through the cycle of possibilities. She just wanted to freak AJ out... It was some kind of prank or joke...

...Or it was for real.

It didn't take her long to realize that of course it was for real. She had slept with Rainbow in her room several times since they started seeing each other, and she always saw that combination lock on the top dresser drawer.

This was a lot to wrap her mind around, and she wasn't going to be able to get to the bottom of it by herself. But who could help?

Needless to say, things were awkward with her and Rainbow right now. They hadn't seen each other in a week, ever since she took off from her room. She saw her around town handling the weather, but Rainbow always kept her distance, so AJ knew she was still embarrassed.

She considered Twilight for a few moments, but their relationship was known to their best friends, so she didn't dare give them the slightest hint of Rainbow's kink. She began to think something was a little wrong when AJ returned the balloon that night, instead of the next morning like she had planned.

'Where does she get those supplies? I'm sure they have to know at least a little about it.' Applejack thought to herself. She didn't have the best photographic memory, but she was pretty sure she saw 'Silly Filly' on the front of the diapers and foal powder. It was a foal care supply store right here in town. Was that where Rainbow was getting these things?

It only took another day of Rainbow ignoring her during weather duties for her to make up her mind and go get some answers.

Applejack found herself walking in the marketplace of Ponyville the next day after work. She had never been to the Silly Filly store. When Apple Bloom was just a foal, she got what she needed at Barnyard Bargains. Filthy was more than happy to give the family a discount, due to their history, as well as the fact that their mom had died during childbirth. So needless to say, she had to do a little searching. After going up both sides of the street, she found it; the store's signage was rainbow-colored and playfully shaped. She walked in the double doors, and recognized the cashier, Gentle Care, a regular customer at her apple kiosk. His wife, Soothing Care, was doing inventory of an order behind the counter before stocking the shelves.

“Hello. Ah, Applejack! You're not someone I would expect to see here.”

“Yeah, I know. Don't worry, I'm not knocked up or anything. I just need some... Advice.”

“What can I do for you?”

Applejack took a quick look around, making sure there was no one else in the store, before leaning on the front counter.

“There's no way to put this delicately, so I'm just gonna come out and say it. The other day I was at my marefriend's house. She said she had something to show me. She showed me diapers from your store, and they were in her size... Adult size. Things have been awkward between us since, and I'm... I'm just having a hard time wrapping my mind around this, and I had to talk to someone.”

Gentle turned to his wife.

“Get the sign, hun.”

Without a word, Soothing came around the counter, and flipped the sign on the door from OPEN to CLOSED, returning to her husband's side, and prepared to help explain things to Applejack.

“You're closing shop just to talk with me?”

“Privacy is the first thing I give my special customers.”

Applejack slowly nodded.

“Alright, first things first, I suppose. Chances are, your marefriend is an adult foal.” Soothing began.

“Adult foal?”

Gentle nodded.

“A stallion or mare who likes to act like a foal, or sometimes a bit older, like a filly or colt. It usually involves items you associate with foals, most commonly diapers, but it also branches out to bottles, pacifiers, and even a crib and other related furniture.”

“Why is she like this?”

“That could be any number of reasons. It could be an event that happened around that point in their lives, or something else entirely. For some it's just a way to relieve stress and unwind from everyday life.”

Now she was starting to get somewhere.

“So how do they know that this place has things in their size?”

“At first they don't. But I've found it's helpful to be forward with them. If I see an adult with no accompanying foal wandering the diaper aisle for any prolonged length of time, I simply come up to them, and ask if there's anything I can help them find. I ask if the right size is on the shelf or if they need something bigger. It's small hints like that that get them to open up. If they ask how big, I casually say our sizes range from foal to adult. Sometimes they decline at first, walking out a bit embarrassed, but most of they come back, either hours, days, or weeks later. When they realize that they're not alone, that there are enough adult foals around to warrant a supply store that caters to them, they feel much better. We even offer discreet shipping services so they don't have to come in all the time.”

“How do you know all this?” Applejack asked the mare.

“Well, because I am one.”

Gentle came up next to her.

“I've always had an inner need to care and nurture somepony. When we met each other in Fillydelphia, we slowly opened up to each other, and I was understanding all the way through, knowing that it was meant to be. When we discovered that there were others like her, we decided to start a business, and sell foal supplies for ponies of all ages.”

Applejack's expression changed from bewilderment to sadness.

“I wasn't understandin' at all. I was so stunned by it that I didn't say anything for so long that she snapped and ran off... I mean it was so unlike her everyday self that I didn't know what to think.”

“Yet here you are, getting more information, so you can better understand.” Soothing replied.

“So what do I do?”

“Well, you should understand a few things. Adult foals are almost always very, very secretive of this side of them. If she was brave enough to show you, then that means she has a great deal of trust in you. Know that it's a part of who she is.”

Applejack nodded.

“Secondly, since you're her marefriend and you two are already close, she may want to involve you in this. Sadly, that is an element that a lot of adult foals are missing; a caretaker. So few of us get to share this fantasy with somepony else who understands. Do you think you could treat her like a foal if she wanted you to?” Gentle asked.

“I... I honestly didn't think of that.”

“If that is what she wants, know that it will make her the happiest mare in the world if you can bring yourself to do that comfortably. Again, it's a fantasy that many adult foals have unfulfilled. But also as her marefriend, don't forget the 'adult' part of adult foal, if you catch my meaning.”

Applejack nodded again.

“Can... Can I see what you have?”

“Certainly. Right this way.”

The farmer was welcomed around the counter into the back storeroom. There was all manner of supplies. Boxes of diapers, both cloth and disposable, individually packaged pacifiers, bottles, and sippy cups. Jars of baby food, sets of plastic bowls and feeding spoons. Containers of wipes, bottles of foal powder and oil; things necessary for changes.

All these things were sorted in different sizes, and in the very back, were the adult sizes. Everything you could imagine for a foal, except bigger.

Applejack slowly scanned the shelves with her eyes.

“Any more thoughts on your mind?” Soothing asked.

“The diapers, they... They use them?”

“It depends on the pony. Some just like wearing them, some only wet them, and others use them for both, like full-on foals. Then some even use them for number 3.”

“Number 3? You mean...?”

She nodded.

“Yes, it is a sexual fetish for some. It's not that farfetched, when you consider the area diapers are wrapped around, and that we're mature stallions and mares.”

Applejack slowly nodded, taking all this information in.

“Yeah... So, her birthday is next week. I think... I think this may be the best way to apologize. How do I know what to get?”

Soothing smiled.

“Well, go off on what you saw, and didn't see, in her drawer when she showed it to you. Were the diapers cloth or disposable?”

“Disposable.”

“Alright. Those are more convenient than cloth, and if she has room, the more diapers, the better. Anything else?”

“Yeah, a bottle of foal powder and a foal bottle for nursing.”

“Well, it sounds like you could help her complete her foal experience. Some mashed food, spoons, formula, bowls... I think two weeks is enough time to get some special things made, if you're interested.”

Rarity was engrossed in her sewing machine when there was a knock at her door.

“Just a moment!” she called, turning her sewing machine off and going to the front display floor, opening the door.

“Oh, hello there, Applejack. I trust your day is going splendidly. What can I do for you?”

“Hey there Rarity. Listen, I need Rainbow's measurements. I thought you might have those from when you made our gala dresses.”

“Yes I certainly do. One moment.”

Rarity disappeared into the back room. Applejack could hear drawers opening and closing. Two minutes later, she came back up front with a single sheet of paper.

“Here you go. Planning on making her something? I'm not sure if I should be offended that you're going to somepony else!”

“I hope you don't. Yes, it's a birthday present, and it's a bit more on the personal side, so if you'll be excusin' me. Thanks!”

Rainbow's heart ached as she came in for a landing on her front step. The last two weeks hadn't been easy. Sooner or later, she was going to have to get over this and confront Applejack, regardless of what she thought.

Before heading inside, she checked her mailbox, and found a letter. There was no address or stamp, so someone must have dropped this off personally. She tore the envelope open and unfolded the letter.

Hey hun,

Regardless of how you're feeling about just leaving me in your bedroom like that, I don't think we can avoid each other forever, especially not with your birthday coming up tomorrow night. I've got it all planned out, so meet me at the farmhouse tomorrow night at 8:00.

Love you always,
Applejack

Birthday For A Baby

Birthday For A Baby

Rainbow's heart pounded against her chest as her hooves landed on the dirt of Sweet Apple Acres, just inside the front gate. She slowly trotted up to the farmhouse, the awkwardness settling in again. Applejack's letter had done wonders to calm her nerves, but now that she was about to look at her marefriend face to face for the first time in over two weeks, her nerves were becoming a bit frazzled all over again.

She came up the steps, and the front door was opened before she could knock, and there stood Applejack, smiling.

“Well, there's my favorite mare in Equestria.” Applejack said, coming forward and hugging the pegasus. “Happy birthday sweetheart.”

With that, Applejack invited her in, showing her to the back bedroom. Together, the two of them sat down on the bed.

“I know the traditional thing is usually dinner, then presents, then cake, but I figured we'd do things a little different this time around.” Applejack told her. Rainbow shuffled nervously in her sitting position on the bed.

“Look, we've been dancing around this awkwardness for the past two weeks, so I'm just gonna come out and say it. I'm... I'm sorry for letting this thing out in the open and all. It's just that with how much we mean to each other, it didn't feel right hiding any part of me from you.”

“Don't be sorry. If anything, I'm sorry for reactin' the way I did. I saw how nervous you were, and I didn't do anything to calm you down. You just wanted to share every bit of who you are with me, and there ain't no shame in that. To show you how sorry I am, I got ya a little something.”

Applejack went to the closet, and came back around with two gift-wrapped boxes, and set the smaller one down on the bed in between her and Rainbow.

“Happy birthday, hun.”

Rainbow untied the bow, and tore off the wrapping paper, and quickly removed the lid. Upon peering inside, her eyes widened, as did her smile. Her hooves reached in, and came out with a Daring Do plushie. She hugged it tight.

“Aww! It's awesome! Thanks!” she said, smiling at Applejack. Applejack smiled back, and moved the first box out of the way to make room for a second.

“That was nothing. This is what I worked to get done on time for your birthday.”

With that, Applejack slid a considerably larger box in front of Rainbow. She undid the bow and lifted the lid once again, and this time, her face was more disbelief than immediate joy. Placing her front hooves on the sides of the box, she leaned forward, and peered inside.

Inside, neatly organized, was a bottle, pacifier, and bib, all with her cutie mark on them, a set of hooved fleece sleeper pajamas with the Wonderbolt insignia patterned on it, several jars of baby food, feeding spoons, two bottles of foal powder and of course, two dozen diapers. All in her size.

“I hope you don't mind, I asked Rarity for your waist measurements, since we'd never bought each other any clothes. I wanted to make sure I got the right size.”

Unable to take her eyes off the contents of the box, she finally was able to keep her mouth from hanging open.

“You... You went to get these from Gentle and Soothing Care at Silly Filly?”

“I saw the name on the packs of diapers when you first opened the drawer. I mean, if we're celebrating your birthday down here, how else am I gonna be able to make you my adorable little foal?”

This finally brought Rainbow's eyes up from the box, to meet Applejack's smiling face.

Biting her lip, Rainbow pushed the box to the center of the bed, slid forward, and threw her front hooves around her marefriend, before taking a shuddering breath and began weeping into her mane, her shoulders quaking. Applejack quickly returned the embrace, rubbing her back, confident that these were tears of relief and joy.

“I was so stupid about this whole thing,” Rainbow began to whisper through her sobs. “I had this whole explanation put together in my head, and it all fell to pieces when I finally showed you. Then because I bolted when it got too awkward, you go and get answers from where I buy everything. I was so sc-scared, that I screwed us up... That this was gonna make you fall out of lo-”

“Sweetheart...” Applejack said, interrupting Rainbow's heart-pouring. “You don't need to fret over this no more, ya hear? I couldn't imagine you wanting to act like a foal, even after they explained everything, even as I was picking stuff out... But I guess I'm gonna find out tonight, because they made it absolutely clear how special this is to you. So I wanted to make it crystal clear how special you are to me. I love the side of Rainbow Dash that's athletic and brash, if a bit egotistical. I'm sure I'll love this side of you too.”

Applejack released Rainbow from the embrace, wiping the tears from her marefriend's eyes.

“I'm sure you're quite hungry for dinner, but before I can do that, first I have to get my fully grown foal into her diaper, don't I?” Applejack said, playfully shoving Rainbow onto her back, before reaching over to the box to get one of her new diapers from the box along with a bottle of foal powder. When she came back to between Rainbow's back legs, she noticed an instant change had taken place in her marefriend. She was embracing her new Daring Do plush with one hoof, and sucking on the tip of her other.

“Now now, that's what this is for.” Applejack said, reaching back over to the box, and got the new pacifier, and slipped it into Rainbow's mouth. As she began to gently suckle on it, she looked up at AJ as she got the diaper unfolded and made sure the tapes were on the right end.

'Here goes nothin' Applejack thought to herself. She lifted the tip of Rainbow's tail and threaded it through the tailhole in the back. Once it was through, she lifted Rainbow's rump off of the bed and slid it up to the base, making sure the back wings were flattened out before setting the pegasus down. She twisted the bottle of foal powder open, sprinkled a liberal amount over her diaper area, rubbing it in, and then brought the front of the diaper up between her legs, smoothed the front side up against her stomach, and then brought the back wings up and taped it up securely. Seeing Rainbow wiggle her legs a bit, making it crinkle was very cute, AJ had to admit. Still, that wasn't as hard as she thought it'd be.

The last piece of advice the Cares had given her was that every adult foal is different, and the only way to figure out what they wanted was to experiment. So she decided to approach it using her experience raising Apple Bloom. So she leaned down quickly and gave Rainbow a raspberry on her stomach, and hearing the muffled giggle Rainbow gave through her pacifier made Applejack's heart skip a beat. She pulled Rainbow up to a sitting position and went back to the box.

“Alright, time for num-nums.” she announced, grabbing a jar of applesauce and feeding spoon from the gift box.

The Silly Filly supply store spared no detail. The adult size spoons had rubber ends, and the jars of baby food were in the appropriate serving sizes, otherwise she'd be here all day feeding Rainbow the proper amount for dinner. AJ got the bib from the box and tied it around her neck. She was getting cuter by the second.

She unscrewed the jar lid and got a spoonful of applesauce. She brought the spoon to Rainbow's mouth, only to have her keep her lips sealed and try to turn her head away from the spoon. Applejack, playing along, timed it right, and gently slid the spoon in between her lips, getting some on her chin and bib in the process. The farmer couldn't help but smile. She scooped up what had dribbled down, and got the rest of it in Rainbow's mouth.

Rainbow, of course, switched up her game. On the next bite, she gave AJ a break, but on the third, she took it in, and as Applejack was preparing the fourth, Rainbow slowly spit the applesauce out, letting it drip down her lips.

“Ah ah ah, back in there.” Applejack chastised, somewhat amused at the authenticity of Rainbow's role play. As she got the hang of things, Rainbow made things less of a hassle, and simply took the food as it came. Once the jar was empty, she set it on the nightstand while Rainbow laid back down, satisfied.

“Alright, my little Rainbow. I'll be right back.” She told her, grabbing the adult-sized foal bottle from the box and got up to go to the kitchen. Once she was there, she flipped on the light and went to the fridge, grabbing the pitcher of apple cider. She untwisted the rubber nipple, carefully poured the bottle full of her family's famous beverage, then screwed the nipple back on before replacing the pitcher in the fridge. Returning to her bedroom, she saw Rainbow on the bed, smiling at her, a smile that widened when she saw the contents of the bottle. AJ got back up on the bed, and was getting ready to give Rainbow her bottle when she noticed the blue sky landing zone of her diaper had turned to a darker thundercloud graphic.

“Uh oh, did my little Dashie wet herself?” AJ asked, causing the pegasus to blush at the cheeks. The farmer softly pressed against the diaper, and got a light squish sound in return.

“Doesn't seem too soaked right now. Alright, here we go.”

Applejack slid up to the head of the bed, taking a reclining position, and ushered Rainbow up next to her. She gently guided her head down to where it was laying on her lap. Now that she was comfortable, she put the nipple up to Rainbow's mouth, and slid it in between her lips. She immediately began to suckle, and the cider flowed into her mouth and danced across her taste buds. She lightly squirmed her legs as she nursed from the bottle, enjoying the squishy crinkle sound she got from it. Applejack noticed this, and reached a hoof down to lightly pat the front of her diaper. When the bottle was half empty, she heard a light rumble come from Rainbow's stomach.

'She still can't be hungry, she's had plenty so far.' Applejack thought to herself. There came another rumble, and as the bottle got to a quarter empty, Applejack felt Rainbow tense up slightly, followed by a wet fart, and more crinkling sounds from the diaper. It didn't take her long to deduce what Rainbow just did. By the time she was finished with the bottle, the smell had reached her nose.

“Rainbow, did you make a stinky?” Applejack asked in her best motherly voice, making Rainbow blush even more. She reached down a little father with her hoof and pushed against the seat of her diaper, getting a warm, resistant squish in return.

“Yep, you're definitely a smelly filly.” She said, giving her behind another good swat, encouraging her to get up. Rainbow sat up while AJ went to go get a towel.

“Alright, let's get you changed.” AJ said, unfurling the towel and putting it on the bed, then proceeded to grab Rainbow by her hind legs and pull her from the head of the bed down towards the end, so her diaper area was on the towel. She grabbed a fresh diaper, and the box of wipes from the box beside her. She tore the tapes off one by one, then slowly opened it up. The front of the inside was soggy and yellow, and the back was smeared with her manure, which smelled that much stronger now. Dealing with barn animals on a daily basis, Applejack didn't seem to be disgusted in the slightest. The only thing that surprised her was the volume of it; much greater than was an ordinary foal would produce.

The adult sized wipes, along with a pair of wet washcloths, made the job a whole lot easier. Applejack had the dirty diaper wrapped up and thrown away in under three minutes, and a fresh one laid out under her. The smell of the baby powder was a very welcome change from Rainbow's messy diaper. AJ took note of how excited that had made Rainbow, seeing her glistening marehood as she powdered her nethers. Applejack briskly went over to her nightstand, and pulled an item out of the drawer.

Rainbow was snapped out of her euphoria when she felt something poke at her sex. She glanced down at Applejack, still blushing.

“Appujack?” She asked, her speech hindered by her pacifier.

“Well, I took care of the 'foal,' now to take care of the 'adult.'”

Applejack gently and easily slid the egg toy inside Rainbow and strapped the controller to her thigh before bringing the diaper up and taping it securely shut.

“Keep that pacifier in your mouth, hun. We don't want you making too much noise.”

With that, Applejack turned the knob of the controller on, slowly increasing it to it's highest setting. Rainbow let out a gasp, but kept the nipple of the pacifier in between her teeth. When Applejack had the dial at it's highest setting, she climbed up on the bed on top of Rainbow, and began grinding against Rainbow's diaper, kissing her neck.

The diapered pegasus was in absolute bliss. The vibrating inside her, the crinkling of the diaper as she squirmed, and the weight of her marefriend on top of her was rapidly pushing her towards the edge. She was only half surprised; being diapered, fed, messing herself, and getting changed by AJ was more than enough to build her up. She began to moan through her pacifier as AJ thrust into her harder, nipping her neck now.

With a muffled squeal, Rainbow came, releasing into her clean diaper. Applejack reached down and turned the vibrator down to low, only to turn it back up to high after five seconds and press against Rainbow's padded pussy, bringing her to a second peak. Rainbow's eyes crossed, becoming overwhelmed with pleasure as Applejack pulsed the vibrator from low to high, keeping her in her second climax as long as she could. After a minute, her body went limp, and Applejack turned the vibrator off, gently pulling it out of her and the diaper through the leg gatherer.

“Well look at that,” Applejack began, patting the front of her marefriend's diaper again. “I just changed you and you've already gotten this one wet again. Just what am I going to do with you?”

Not being able to take it anymore, Rainbow let the pacifier fall from her mouth, and pulled Applejack into one of the most heated kisses she could remember giving. Their tongues danced together for over half a minute, and they both parted, gasping for air.

“Best... Birthday... Ever...” Rainbow panted.

Applejack smiled back, pulling the covers back and getting the light on the wall. She removed her hat, and slid under the covers next to her marefriend.

“Happy birthday, my adorable little Dashie.”

Author's Note

There ya have it. I hope the targeted audience enjoyed. I know this story was a bit barebones, but this was my first attempted ageplayer story,and I didn't want to derail it with fluff.

Thanks for reading!
