Magic Kindergarten

Twilight Sparkle sat in the throne room of Princess Celestia’s castle in Canterlot.

A day had passed since she had made the mistake of trying to create a friendship problem by enchanting her smarty pants doll and having everypony in Ponyville argue over it.

Twilight knew it was wrong. She had let her worries get the best of her and had used her magic to hurt other ponies.

Now she had to face the consequences of her actions.

Princess Celestia hadn’t quite elaborated on what her punishment would be, but she did promise her friends that Twilight would return to Ponyville in a few weeks when it was over.

Even Spike had been asked to stay behind, the Princess insisting this was something Twilight needed to learn herself.

At that moment, the throne room doors opened and the Princess began walking inside.

Twilight immediately bowed in respect, trembling slightly.

She hadn’t slept a wink last night wondering what the Princess was going to do with her.

Princess Celestia made her way to her throne and sat down before addressing Twilight.

“Good morning Twilight. I hope you slept well. I’ll get right to it. I’ve brought you back to Canterlot because I feel you need a bit of a refresher on friendship. I understand that nopony is perfect, and I hope you understand that as well, but your actions yesterday leave me no choice I feel but to send you back to Magic Kindergarten.”

Twilight couldn’t believe it. It was her worst fear realized.

“It is only temporary and it will be private lessons with me, but I think focusing more on your basic socialization skills will allow you to build a more solid foundation in understanding friendship. Does that make sense?”

Twilight nodded. She was still a little upset she had to go back to Magic Kindergarten, but at least she wouldn’t have to face the humiliation of being in a class with young ponies. Plus Celestia had said it was only temporary.

“Good. Follow me and we’ll get started.”

Princess Celestia stood and walked out of the throne room with Twilight close behind her.

They didn’t have to go far before Celestia stopped in front of a random door and walked inside, closing it with her magic as Twilight entered.

Twilight was shocked at what she saw.

The room around her looked almost identical to her classroom she had studied in when she was a young filly.

Cabinets along one wall, a teacher’s desk, a chalk board, a globe, and a few odd books here and there.

The only difference was instead of a few desks in the room there was only one, about three yards away from the teachers desk and sized for a grown mare rather than a little filly.

Celestia went and stood in front of the smaller desk.

“Good ahead and have a seat Twilight.”

Twilight did as she was told, walking over and taking a seat at her desk.

“Now before we begin, I know you’re anxious given everything that’s happened, so I want you to try a relaxation exercise with me. I want you to be able to focus entirely on our lesson.” Said Princess Celestia.

“Ok Princess.” Said Twilight.

As much as she didn’t want to admit it Celestia was right. She was worried about doing something else wrong and ending up having to stay in Canterlot longer.

She missed Spike and her friends and wanted to get back as soon as possible. She knew she needed to focus on what the Princess taught her.

Celestia picked up a pocket watch on the teacher’s desk with her magic and began to swing the watch in front of Twilight’s eyes.

“I want you to focus on the watch as it swings.”

Twilight did as she was asked, focusing on the watch’s rhythmic movement.

“You should start to feel sleepy any moment. This is normal.”

Twilight’s eyes began to close slightly, her mind getting groggy.

“Can you hear me Twilight?”

Twilight just lightly nodded her head.

“Good. Now listen carefully to the sound of my voice. It’s time for you to get ready for today’s friendship lesson Twilight. But for this one, we don’t need grown up Twilight. No, we need big filly Twilight. I want you to think back. Back before meeting your friends, before your college classes, before high school, and even grade school. Think back to when you were just a little filly in kindergarten. You’re four years old. You don’t have your cutie mark yet. You’re very smart for your age and eager to learn. Now, when I stomp my hoof, I want you to forget everything you remember from after you were in kindergarten. We’re gonna put those memories away on a shelf for a while until you need them again. Nod if you understand me Twilight.”

Twilight nodded her head.

Celestia stomped her hoof on the floor and Twilight’s eye’s fluttered open.

“So Twilight, are you ready for your lesson?”

Twilight beamed at her with a smile of unfiltered enthusiasm.

“Yes Princess Celestia!” Said Twilight with a filly dictation.

Princess Celestia smiled and cast a spell, sending a magic beam in front of Twilight’s desk.

The beam took form into a translucent figure of a pony that looked just like Minuette, a filly with whom Celestia remembered Twilight had gone to kindergarten with.

“I want you to make small talk with this filly. Try and form a relationship with her.” Said Celestia.

“Do I have to? Can’t we practice magic instead?” Whined Twilight.

“Yes. This is important Twilight. You need to learn to befriend other ponies. You won’t get far if you don’t.”

Twilight sulked but did as she was told.

Her attempts were hard to watch.

She didn’t have any idea what questions to ask or how to carry a conversation.

Despite Celestia giving her many pointers and starting over multiple times, Twilight could just not seem to put the concepts into practice.

Two hours later and she had made no progress.

Celestia’s notoriously long patience was starting to wear thin.

She had known Twilight had been bad a making friends before, but what she was seeing was almost incomprehensibly bad.

Twilight had clearly had enough. It was time to try something else.

“Alright Twilight that’s enough. Let’s take a break and try again in a couple minutes.” Said Celestia as she rubbed her temples with her hooves and took a seat at her desk.

Twilight ran over to the book case and picked up a science book, returning to her desk and beginning to read through it.

Celestia began to think. There was no way to get Twilight to grasp this material, or at least not as quickly as she needed to. She had promised Twilight’s friend’s she would be back in a few weeks, and at this rate it was looking like it’d take years!

Maybe…A thought began to form in Celestia’s head. If Twilight’s early influences in her life had already lead her to believe that friendship was not worth pursuing, maybe going further back in her life would allow Celestia to give Twilight those skills and yearnings!

This of course would be a bit harder. Twilight hadn’t meet her until she was a filly, and changing too many of her lived experiences could have dire consequences to Twilight’s mind.

A new kind of teacher would be necessary for these lessons.

Celestia once more picked up the watch with her magic and began to swing the watch in front of Twilight’s eyes.

“Twilight, I want you to focus on the watch as it swings.”

Twilight did as she was asked, watching the watch move back and forth.

“You should start to feel sleepy any moment. This is normal.”

Twilight’s eyes began to close slightly, her mind getting groggy again.

With Twilight preoccupied, Celestia began to make the necessary changes. She cast a spell on the room, changing it from a kindergarten classroom to one geared toward younger ponies.

The books on the shelves became thinner, many of the words being replaced with pictures.

The hard tile floor became carpeted and the walls were now painted bright yellow.

Twilight’s desk disappeared and was replaced with a bean bag chair.

Toys littered the floor.

Lastly Celestia’s teacher desk was poofed away, a simple table and chair taking its place.

Celestia then cast a spell on herself, her body glowing with her magical aurora.

The large alicorn began to shrink down until she was about Twilight’s height.

Her wings receded into her body.

Her coat darkened slightly while her mane and tail shortened and changed from its multicolored hues to a simple bright white and soft purple striped style.

Her cutie mark changed into three purple stars on either side of her hips.

Lastly, her purple eyes changed color to a light blue.

She had transformed herself into Twilight’s mother, Twilight Velvet.

Celestia looked over herself, making sure her new form looked correct.

Satisfied, she poofed her magic regalia away, the items now much too large for her smaller body, and turned her attention back to Twilight.

“Can you hear me Twilight?”

Twilight nodded.

“Good. Now Twilight, I know you were having trouble with our lesson before, but that’s ok. Mommy is here now to help you and thinks she knows just what you need. But she’s going to need your help. Can you do that sweetie?”

Twilight nodded.

“Good. Now you did a good job thinking back to when you were a filly, but now you need to go farther back. Back to when you were just starting preschool. You’re three years old. You don’t know how to do much of anything on your own yet. Your mind is a blank canvas just begging to soak up all the knowledge it can. Now, when I stomp my hoof, I want you to forget everything you remember from after you started preschool. We’re gonna put those memories away for safe keeping. Nod if you understand me Twilight.”

Twilight seemed to struggle for a second but nodded her head.

Celestia stomped her hoof on the floor and Twilight’s eye’s fluttered open.

“Hello sleepy head! Did my little girl sleep well?” Asked Celestia.

Twilight rubbed her eyes.

“Yesh Mommy. I was vwery sweepy.” Said Twilight with a toddler like lisp.

Celestia had to admit it was cute seeing Twilight like this.

She had always been close to her pupil, and having no children of her own had lead her to look at Twilight as a sort of adopted daughter, always happy to teach her and see her succeed.

Many other teachers may have been more hands off with their teachings, but not her.

She would always be there to help Twilight when she needed her, just like now.

As Twilight got up from her seat she began to look around for something.

“Mommy, where’s muy pwull-up?” Asked Twilight.

The question took Celestia by surprise for a second.

She hadn’t considered when she put Twilight under that her toilet training would be affected.

But Celestia had told her to forget everything from after she was three so it seemed natural that most three year old ponies would be in the stages of potty training.

Celestia used her magic to produce a mare sized pack of pull-ups, pulling one out to put on her young charge.

“Right here sweetie. I took off your wet one before I woke you up.” Lied Celestia.

Twilight however was none the wiser, trusting her Mommy whole heartedly as she laid down and allowed her to slide the absorbent panties up her legs and around her flank.

They were white, with pink printed frills and stars on them that would fade to let everypony know when they were wet.

“There we go sweetie. Now are you ready to go play?” Asked Celestia.

“Yay!” Squealed Twilight as she trotted off to figure out what to play with first.

For this lesson Celestia wanted to focus on a child’s first basic learned lesson in friendship, and that was playing with dolls and plush animals.

Celestia had made sure to have a wide variety of dolls and plushies sat around the room to help encourage Twilight to do just that, and sat down to watch how Twilight would do.

Twilight crinkled around the room, picking up all the plushies and arranging them in rows.

Celestia found this quite peculiar. She had expected Twilight to read a book with some of them or have a tea party.

Instead she seemed to be organizing them by height.

Soon Twilight had all the plushies arranged neatly into three rows of eight.

She then went over and grabbed some paper and crayons.

Was she going to pretend to draw with them?

Twilight sat a piece of paper and crayon in front of each one, before return to face them.

“Cwass, today we gwonna pwactice owur addwition.”

Celestia slapped her forehead and moaned.

Twilight was pretending to be a teacher and was telling the plushies what to do! She wasn’t treating them nicely like friends, but more like subordinates!

She trotted over to try and give Twilight a nudge in the right direction.

“Twilight honey, why don’t you try having a tea party or read with your friends?” Said Celestia.

Twilight looked at her Mommy with an annoyed expression.

“No! Wanna pway teacha!” Yelled Twilight at Celestia.

Celestia was taken aback by Twilight’s actions. She had never seen her misbehave like that.

“Twilight, I think you’ll find it much more fun to-”

“No! Thwats stooped!” Yelled Twilight again and turned back to continue her make believe lesson.

Celestia was beginning to boil with rage inside.

She had been at this all day at this point and had gotten nothing but pushback.

If Twilight couldn’t learn friendship as a toddler, then there was only one more step back Twilight could go where Celestia could make a dent in her psyche, and that was her infancy.

In her moment of rage, Celestia used a spell she had learn ages ago, one that was meant to be used as a last resort for the safety of Equestria where all matters of reason had failed.

She channeled the spell and shot it at Twilight with her horn, the powerful blast shooting right into the mare’s ear with great force.

Twilight’s eyes went wide as millions of neurons began firing at the same time inside her head, Celestia’s magic taking hold as it forced her brain to make the necessary changes of temporary emptying her brain of all its knowledge but basic instincts. Walking, talking, bladder control, bowel control, complex emotions, and so much more left the mare’s mind in an instant like an eraser to a written word.

When the magic had finished its work, Twilight fell to the floor unconscious, the magic taking a hard toll on her body to the point of exhaustion.

Celestia stood not far away from Twilight, still in Twilight Velvet’s form and panting from the amount of magical energy she had just put out. Maintaining her disguise and performing such a powerful spell had taken a lot out of the alicorn, and as her she caught her breath and began to calm down, she noticed how Twilight was now laying on the floor.

She immediately ran to her student’s side and picked her up in her hooves.

Concern and worry plagued the Princess’s mind. She should never have used that spell. She had promised to never use it after she had learned it. It was far too dangerous to use without possibly seriously injuring or even killing somepony! And yet she had just used it on her prized pupil in a moment of weakness.

“Twilight! Twilight please wake up! I’m so sorry! You have to be okay you have to be!” Celestia said, tears welling in her eyes and she lightly shook Twilight’s still body.

She was about to give up hope when she saw Twilight’s eyes open.

“Oh Twilight! Thank goodness you’re alright.”

Twilight gazed up at her with a wide eyed expression.

“Gaga goo gee.” Babbled Twilight up at Celestia, drool running down the sides of her mouth.

Celestia let out a sigh of relief. The spell had done its job perfectly.

She had crafted the spell in a haste to close off all memories Twilight had up until the moment she had first been born.

Twilight now had the mental capacity of a newborn foal. A completely blank slate for Celestia to work with.

Now she could really get to work.

Or so she thought anyway.

Twilight’s face began to contort into an odd expression, one between concentration and struggle.

Celestia didn’t have to wait long to wonder why Twilight was doing this however as she heard the telltale crinkling of her pull-up below.

Upon looking down at it Celestia could see the garment dropping fast, the stars disappearing as the grown foal soaked and loaded her diaper in mere moments until it looked like it would fall off her at any moment.

When Twilight finished she just giggled, poking a hoof at the front of the squishy garment.

“Well it’s a good thing you were wearing that.” Said Celestia.

It was honestly a surprise Twilight had gone almost the whole day without asking to go to the bathroom.

Luckily magic was on Celestia’s side.

Her horn glowed as she poofed the pull-up away, then summoned some wipes to wipe Twilight’s crotch and butt down from her mess and poofing them away as well.

She then aimed her magic accordingly and poofed a garment more suited to a foal’s daily movements then a pull-up onto Twilight’s rear.

A thick, white disposable diaper was wrapped around Twilight’s butt. The thickness caused her legs to bow outward from her spot on the floor.

Not that it mattered. She didn’t yet have the knowledge of how to move herself about.

Her diaper was fastened snuggly by two purple tapes on a purple landing zone at her waist.

Celestia then used her magic to alter the room once more, changing the playroom into a simple nursery with a crib, changing table, lounging pillow, and a toy box.

She picked Twilight up and carried her over to the pillow, lying down with her.

It was time to feed her baby, and she knew just how.

She cast a spell on herself and shuddered slightly as a slight tinkle began to make itself known just above her crotch.

Right before her and Twilight’s eyes, her breasts began to swell, filling with milk to feed her little foal.

Twilight’s infantile instincts kicked in and she began reaching for her Mommy’s boobies.

Celestia moved Twilight over until her muzzle was right against her one nipple, the foal only taking a moment to latch onto it and begin drinking from her.

Celestia could not describe the feelings she was experiencing as she laid there, watching her student drink from her breasts.

It was a strange mixture of pride, contentment, and perhaps pleasure at seeing a foal rely on her for such simple things. Even if her body was fully grown the fact of being able to provide Twilight the love and nourishment she needed filled her with a sense of pride at the act of being a Mommy for her.

Soon though Twilight had drank her fill of her breast milk and laid there until Celestia brought her up and burped her.

She then carried Twilight over to her crib and laid her down. The sun was beginning to set which meant it was time for little babies to go to sleep.

Celestia stood there for a moment and looked down at her.

Twilight looked up at her with a goofy smile, her eyes wide as they gazed at her Mother, her limbs spread out in all directions since her brain didn’t know what to do with them other then suck on them.

Celestia couldn’t get over how adorable Twilight looked, her little foal just happy and content with lying there.

She started the mobile up and began walking toward the door, ready to call it a day herself.

As she reached the door, she turned around and faced Twilight’s crib.

“Goodnight my baby.” She said, closing the door behind her.

The next two weeks flew by after that for Celestia.

The first half of the week consisted of her giving Twilight lots of love, cuddling her, nursing her, changing her diapers, and just generally being a loving mother.

She gave her lots of plushies to hold which Twilight quickly took to, a welcome change to her preschool self.

After half the week was up, Celestia used her magic to grant Twilight some of her knowledge back, returning her to a three year old but implanting her infantile memories of love and affection she’d had the past few days throughout to help her in her friendship development.

Her preschool self was like a new pony, being nice to her plushies and dressing them, pretending to feed them, read to them, and even having tea parties.

She did play teacher a little, but Celestia was happy to see her more helping her plush friends one on one rather than lecturing.

She was glad to see her magic was working, changing Twilight just slightly to give her that extra edge in her willingness to be a good friend.

After a few days of preschool play and only a few wet pull-ups changed, Celestia moved Twilight up to kindergarten.

The big filly was still very eager and happy to learn from the Princess, Celestia finally able to return to her normal form around her student.

She excelled in her friendship lessons, for which she took great pride in accomplishing and making her teacher proud of her.

The last few days saw Celestia return Twilight’s entire mind to her, making sure her meddling in her mind had not had any unintended effects.

She was pleased to find her student just as she had been before, albeit a bit friendlier at times with her rather than formal.

Twilight apologized for these moments of course but Celestia either blew them off or even encouraged them.

She wanted Twilight to see her as more than simply just her Princess and teacher, but a friend she could trust and rely on.

She found herself repeating this in kind to her student as they rode in the royal carriage back toward Ponyville, her two weeks of lessons passed with flying colors in Celestia’s eyes.

“I hope to try and visit Ponyville a bit more frequently from now on. I must admit I quite enjoyed spending so much time with you again.” Said Celestia to Twilight who sat beside her.

“I liked seeing you again too your highness. I can’t believe how quick the week flew by. I feel like I learned so much so quickly!” Remarked Twilight.

Celestia chuckled at the comment. If only Twilight had known what they’d done together.

She would cherish these memories for as long as she lived.

As the carriage landed outside Golden Oaks library, Twilight and Celestia got out to say their goodbyes, the two sharing a hug before Twilight walked off toward the door of her library and Celestia got back in her carriage.

She watched her student as the carriage took off into the sky and headed back to Canterlot.

It had been an interesting two weeks for sure, but Celestia now had the confidence that Twilight would be much better off in her friendships because of it.

Plus she had gotten to experience a bit of what motherhood was like.

As she sat back and relaxed on her way toward home, she felt happier then she had felt in quite a long time.

Twilight Sparkle blew out the candle on her desk, making her way toward her bed.

It had been another late night of studying enjoyed, but it was now time for bed.

The memories of the past few days were still fresh in her mind.

Pinkie Pie had thrown her a welcome home party when she had gotten back home.

She was so happy to see her friends again and enjoy their company.

She actually found herself a bit more relaxed around them then she had before, her friends even commenting on how much more confident and friendly she seemed.

She had no doubt it was because of her studies with the Princess.

She was so lucky to have her as a teacher.

The next few days had been spent doing lots of fun things one on one with her friends and Spike, all of them having lots of fun together.

She was glad things were calming down however and her life was beginning to fall back into its normal routine.

As she made her way over to her bed, her head turned over to her number one assistant, snoring softly in slumber.

Her horn suddenly lit up and cast a sound proof force field over the dragon’s bed.

She didn’t want to wake him with what she was about to do.

She walked over to her chest against the one wall and unlocked it, moving a few things out of the way before pulling out two items with her magic and carrying them over to her bed.

In the faint moonlight one could just barely make out a thick mare sized diaper and pacifier.

Twilight laid down on her bed and used her magic to diaper herself, taping the diaper up with ease and then reaching over and placing the pacifier in her mouth and beginning to suckle on it.

For as long as she could remember, she had been fascinated with diapers.

Their foalish smell, their poofiness, their cute designs, everything! She had longed to wear one again not too long after she had finished potty training.

It wasn’t until she was older that she found out about other grown ponies that like diapers too, going to a few raves that had somewhat more infantile attire then others in Canterlot before she came to Ponyville.

This lead to her eventually going to adult foal play dates where she could pursue her diaper fascinations further, doing all kinds of foalish things she dreamed of doing for so long with other ponies like herself!

She missed those days, having to give them up when she moved to Ponyville. But that didn’t mean she couldn’t enjoy some foal time to herself every now and again.

Twilight got into a squatting position and began to push.

She hadn’t gone to the bathroom since noon, which meant more than likely…

A sense of pleasurable relief began to ring through Twilight’s body as it emptied itself, her seat drooping with brown mush and her front growing bright yellow from her rain shower.

She let out a sigh as she finished, wiggling her butt to feel her loaded diaper move around her poofy flank a bit.

She then pulled back her bed sheets and plopped her messy seat down on her bed, feeling it squish against her butt as she sank into it.

Twilight relished the feeling, even squirming in delight at the sensation before laying down and covering herself up.

She always woke up before Spike and would have plenty of time to change herself and poof her paci away before he got up.

As she laid their suckling her paci in foalish bliss, she couldn’t help but feel a happy sense of euphoria as she drifted off to dreamland. It was the happiest she’d felt in a long time.
