It was just another ordinary day in Ponyville as Scootaloo rode her scooter toward her home.
Class had just ended, and she was heading home to get some things ready for her fellow crusaders who would be joining her shortly.
As she proceeded along at a decent speed, she suddenly found herself flying over the handlebars of her scooter and onto the path in front of her, landing in a heap.
The high school senior eased herself to her hooves, rubbing her sore body from the accident.
There must’ve been something in the road she hadn’t seen to cause her front wheels to jam.
Walking to pick up her scooter, she found what looked like a white gemstone. It was small, easily able to fit in the palm of her hoof, and looked pretty plain compared to many of the gems she’d seen at Rarity’s boutique.
She decided to put it in her saddlebag and figure out what to do with it later.
Surely as a gem it was worth something?
She got back on her scooter and continued to her home.
She was there in a jiffy, putting her scooter away and going upstairs to straighten up her room.
Only a few things needed to be addressed.
She made her bed, picked up some scrap paper on the floor from doing her homework the night prior, and…
As Scootaloo looked around her room, her eyes stopped dead on her open closet door.
It held all the typical things a young mare her age would have.
Dresses, coats, a few accessories and other odds and ends.
What stood out however was an opened pack of diapers on the floor, just outside the confines of the closet as if it had been accessed recently.
Scootaloo rushed over and began to work to burry the package in the pack on her closet and away from prying eyes.
Little did anypony know that beneath her cool and awesome exterior that loved doing stunts on her scooter and going on crazy adventures with her friends was a pony that loved to pretend to be a baby.
She couldn’t explain why she liked it.
Laying in her room, diaper around her waist as she pretend she was just a little foal with such simple thoughts and desires.
She secretly had hated growing up and having to take on more responsibility and work.
She secretly wished she could just wear her diapers all the time.
All of a sudden, the rock inside Scootaloo’s saddle bag began to glow, the illumination radiating out from the bag and bathing the room in piercing bright light that blinded Scootaloo before she even realized what was happening.
When Scootaloo was able to see again, she had lost her train of thought.
What had she been doing again?
That’s right! She had just picked out what diaper she was going to wear for her playdate with her friends!
She reached down into the pack and picked out plain white disposable diaper.
It wasn’t near as fancy as some of her other ones, but she wasn’t in the mood to go crazy with her padding today.
She placed the opened pack back in her closet, next to a large variety of other diapers that contained different colors and designs.
Although they hadn’t been there before, to Scootaloo they had always been there.
She had always worn diapers. They were her favorite kind of clothing to wear, their soft confines keeping her bottom nice and comfy no matter where she sat.
As she finished strapping the diaper around her waist, she looked around her room and sighed.
She wished her room was more like a nursery.
This boring big kids room wasn’t fun at all to spend time in.
Again a bright light blinded the orange mare. When she could see again, her room had now changed.
Her former bed was now an oversized crib, complete with bars, mobile, and a wonderbolt plushie.
Her walls, which had been a faded sea foam green, where now covered in wallpaper of clouds and rainbows.
Where her desk once sat a changing table now resided, filled with diapers, foal powder, and baby oil. A diaper pail was right beside it.
A toy chest was right beside it, lid open as she had been getting out toys to share with her friends that were coming over.
Blocks, dolls, stuffed animals, and other baby toys littered the foam puzzle piece floor that sat in the middle of the room.
Behind her was her closet, filled with onesies, sleepers, shortalls, frilly dresses, and other foalish clothes that were made to fit a big foal like her.
Being an adult foal was her whole life! She loved going out dressed as an oversized baby and playing in her nursery!
Just then, she heard a knock at the front door.
Her friends were here!
She quickly waddled her way out of her room and down the stairs, the bulk of her diaper made walking a bit tricky, but years of wearing them had allowed Scootaloo to get use to it.
As far as she remembered anyway.
She toddled to the front door and opened it, squealing with glee to see her two best friends!
“Scootaloo what in Equestria are you wearing?” Exclaimed Sweetie Belle, her and Apple Bloom looking in confusion at their friend who seemed perfectly content to be wearing a foal’s diaper.
Scootaloo frowned. She wished her friends weren’t being so mean to her!
With a flash of light, Scootaloo found herself staring at the closed front door of her house.
Upon opening it, she found her friends standing outside, both wearing diapers around their waists, suckling pacifiers, and holding saddlebags that contained their pajamas, plushies, and extra diapers.
At present, Apple Bloom had on a pink diaper with apples scattered around in, and Sweetie had on a white diaper with drawings of rattles, pacifiers, oneies, bottles, and other foalish things covering the outside.
Scootaloo let her friends inside, the three of them running upstairs and an beginning to play happily with the foal toys. Oblivious to anything being at all wrong.
They had all been adult foals since they could remember, happy to be able to have such great friends to play and act out their foalish fantasies.
After a while, Apple Bloom spat out her pacifier and addressed her friends.
“Hey ya’ll, we better get started on our homework.” She said, getting up and going over to her bag, Sweetie Belle right behind her.
Scootaloo sulked.
She hated having to go to school. She wished they could just play all day!
With a burst of magical light, Scootaloo found her two friends back at their spots on the floor playing.
What had she been thinking about? It couldn’t be important for a big foal like her!
She went back to playing, any thoughts of school far from her mind.
The three friends had never even been to school! They hadn’t even graduated preschool.
The three had never been able to learn the material, and despite many years if trying, many experts told their families it was useless to keep trying to teach them.
They couldn’t count, remember letters, or even write their names. Not that their cared. Big ponies worried about that for them!
After a few hours of playing, Scootaloo began to feel a familiar feeling in her tummy.
She had to use the potty.
As she got up and began to make her way toward the bathroom, she wished she didn’t have to ever stop playing.
The stone was quick to grant her request and in a flash she was right back on the play mat with a empty mind.
The familiar feeling in her tummy told her she had to use the bathroom, followed immediately after by her body letting go, a torrent of pee flooding the front of her diaper and tinging it yellow. A second later, a cramping in her tummy made itself known.
She just relaxed and pushed, easing the uncomfortable feeling as she deposited a load into her diaper seat. She let out a sigh of relief and turned her attention back to the block tower she had been building.
She would get her diaper changed when she was ready.
She had never been potty trained, nor had Sweetie Belle or Apple Bloom. They had never been able to make it to the potty, no matter how many things their parents had tried when they were young.
Eventually, they had given up and just left their little fillies in diapers.
Not that any of them minded. Not having to stop what they were doing to go use a toilet meant they never had to stop having fun! Plus their warm diapers felt extra comfy around their waists.
Before long, Apple Bloom had messed her diaper, followed by Sweetie Belle wetting hers.
The three friends sat content in their warm and squishy diapers, happy to continue their infantile fun.
A little later, Scootaloo’s Aunts came home to find their niece and her friends in their foalish states.
They had been quite concerned and disapproving at first, but the stone was quick to change their minds.
The two mares were happy to have three little baby fillies to care for.
They changed their diapers, taking great care to clean their most sensitive and intimate areas and dispose of their dirty diapers.
They then powered and rubbed rash cream over their crotches and butts before wrapping them back up in their padding.
They then brought the little foals downstairs for dinner.
Scootaloo made a face upon seeing a boring and yucky salad waiting for her.
She wanted something yummy!
In a flash, the bowel on salad on the kitchen table was replaced with three large high chairs for the big foals to sit in, each being buckled in one by one and having bibs tied around their necks so they could be feed.
Such baby fillies couldn’t be trusted to feed themselves after all!
After a nice meal of being spoon fed mashed berry foal food, Lofty and Holiday promised them warm milk, as soon as the bottles had cooled down.
Scootaloo became quite cranky at this news.
She didn’t want to wait! She wished she could have milky right now!
A second later, Scootaloo found her and her friends not in the kitchen where they’d been moments ago, but now in the living room on the floor.
Before them her Aunt Holiday and Aunt Lofty were laying on their sides on large pillows.
“Ok little ones! Time for milky!” Said Aunt Holiday, her and Lofty spreading their hind legs to reveal their breasts.
Both mare’s boobs were engorged, the size of grapefruits and leaking droplets of milk from their teats.
Scootaloo and her friend’s mouths began to water as they waddled forward to receive the sweet treat offered to them.
Aunt Holiday took Sweetie Belle and Apple Bloom, each big foal taking a breast each and latching on to suckle down the sweet liquid within.
Scootaloo meanwhile eased herself over to her Aunt Lofty, slipping her tit into her muzzle and latching, gulping down mouthful after mouthful of milk.
It was a common ritual for each of them to have their milk this way. Cow milk made their tummies upset, and it was essential they get their vitamins.
As such, members of each of their families had a special brew prepared that allowed them to lactate to feed their big foals.
Sweetie usually was feed by her Mommy, but in recent years her big sister had been taking care of her and as such had begun to nurse the grown foal.
Apple Bloom’s sister Applejack usually fed her since her Mommy and Daddy had passed away when she was still a baby. Her family actually believed the reason she was a big foal was a way for her to cope with the loss. Either way, Applejack was happy to help her baby sis.
As the three adult foals suckled, the erotic nature of the situation was not lost on them.
Despite acting and living like babies, they were still grown mares like any other, and the sight of boobs began to make them feel warm inside their diapers.
Little moans escaped around Lofty and Holiday’s nipples as the fillies continued to drink.
Apple Bloom and Sweetie Belle had begun to scissor their diapered crotches against each other, while Scootaloo dug her hoof into her diaper front to try and rub her aching sex.
Her diaper though made it a bit difficult.
She wished there was a better way to satisfy her urge.
A second later, Scootaloo came to her senses and as she suckled, moaned even loader at the large and vibrating object she could feel inside her, hidden from view underneath her diaper.
She bucked her hips against the air as she drank, enjoying the ride as well as the view.
All the while Holiday and Lofty stroked their charges manes and whispered words of encouragement.
This was a common nightly ritual for them.
After dinner they would feed Scootaloo her milk and place her special toy in her pussy before wrapping her diaper back around her waist to prevent a mess.
After a couple of minutes, each of the grown foals came, collapsing in a heap on the pillows and allowing the teats to slip from their mouths.
Holiday and Lofty simply smiled warmly and picked the foals up to tuck them in for bed.
They removed the special toys, placing them in the sink to be cleaned later.
The big babies’ diapers would easily last the night, their naughty fun ensuring they would get a restful sleep.
As Scootaloo was tucked into bed along with her friends, sleep beginning to overtake her mind, a final thought passed through her head.
She wished nothing with her and her friends would ever change.
With a flash that not even a now dozing Scootaloo would notice, the wish was granted.
Holiday and Lofty kissed the forever foals goodnight before leaving them to drift off to dreamland.
The gem remained inside Scootaloo’s toy chest at the bottom, likely never to be discovered again. It would forever fulfill Scootaloo’s ever increasingly foalish desires without question, Scootaloo’s other side now the only side anypony would ever know.
