Chapter Two: The Mother of alicorns

The day started like any other for Celestia as she slowly woke up from a nice long sleep. Yawning, she looked around her room to discover it was pitch black. She couldn't see a thing. The princess squinted as she could barely make out the shape of another pony in the shadows. Judging from the appearance of her body, the pony was clearly an alicorn, but twice her size towering over her bed. The princess gulped nervously as she whispered. "Luna, is that you?"

"Sorry, Luna is rather busy tonight, sun butt." The strange alicorn explained in an odd, motherly tone that sounded much like Celestia herself.

"Huh? Wh-" Before Celestia could finish, however, the strange mare came in closer so Celestia could get a better look of her and gaped in surprise, seeing that she looked a lot like her. Still, the alicorn's mane was a mix of light orange and a dark purple with sparkles in her mane, her coat was a pristine white, but she had spots all over her fur and muzzled was covered in a velvety fur, and eyes were a dark velvet as she slowly removed the blanket and revealed a cute pull-up strapped around Celestia's rump. It was much like a diaper, but the padding was quite thin and instead of straps there was two elastic tabs on the side of them. The odd mare came over and pressed a hoof over it and cooed. "Good job, all dry."

"Wha! What is this!?"

"Your pull-up sweetheart now come on we have to get you all ready to raise the sun."

Celestia heard the voice coming from this strange mare and was a bit stunned as she slowly got up, her now pink mane falling about as she hadn't put magic into it just yet. The mysterious mare plopped her down on the ground and led the princess by the hoof to the bathroom. It was still very early in the morning, so the princess couldn't really make out who this pony was. It looked like her making Celestia feel younger even though she could see they appeared to be the same age.

But she couldn't think much about her situation as they entered the bathroom. Then this strange alicorn flipped on the lights, Celestia saw the first odd thing that stood out, her toilet was gone! In its place was a pink, plastic bowl with her cutie mark printed on it! She didn't have time to really think about anything as this alternate version of herself used her magic to levitate the Celestia over as she pulled her pull-ups down, making the princess squeak out in surprise pressing her hooves over her exposed crotch area then the bigger placed her on the training potty. Celestia sat there stunned with her pull-up pulled down to her ankles, for a second as the other version of herself fixed a timer and explained in a patronizing tone. "Now, sit on the potty for five minutes until you go."

The princess blinked, this was a tactic used by parents to train their foals on how to use the potty, and for some reason, this other version of her was doing the same. "Um...I sorry, but I no need a baby potty!" She blinked, using some odd vocabulary despite that not being what she had in mind.

However, the giant alicorn patted the princess on the head. "Oh, I don't mean to be patronizing, dear. But this is what you have to use for right now."

"But why!?" Celestia cried out, more in shock than true upsetness.

"Because I said so, now do you want to raise the sun?" The odd alicorn cooed.

"Uh, yeah! Tat my favorite thing to do!" Princess Celestia exclaimed, suddenly getting excited for seemingly no reason.

The motherly alicorn bent down to her eye level and added. "Do you want some pancakes for breakfast?"

"Yeah! That's my favorite!" The princess squealed, suddenly bouncing up and down!

"Oh, really? Do you want syrup on those pancakes?"

"Yes! Love syrup!" Celestia nodded.

"How about whip cream and strawberries?" The strange alicorn tapped a hoof to her chin as she went on suggesting.

"Oh yeah! Lots of strawberries! Whip cream! And butter too!" Celestia giddily exclaimed!

"What about some creamy breast milk?" The motherly alicorn suddenly offered.

"Ye- wait for what?!" Celestia asked, kind of confused as to why this imposter would ask such a question.

"Well, you also don't want to piddle or poop in your pampers in front of everypony, do you?" The strange version of Celestia asked.

"What?! Of course not!" The princess exclaimed in horror! The very idea of doing that was humiliating!

"So, will you go potty like a big foal, then?" The imposter hopefully encouraged.

"Uh...yeah..." Celestia nodded and then squealed suddenly as her body actually pooped in the potty with a small plop, followed by a small trickle with a hiss. The mare kicked about feeling so strange and wanted to ask more questions, why had her toilet turned into a training potty? Who was this mare that looked like her? What did the imposter mean by Celestia wouldn't want to poop or pee in her pampers?

Celestia tried to stand up, but the other her cooed. "Now, now, it hasn't been five minutes yet."

"B..Bu, I went potty!" Celestia protested.

"I know, but we need to make sure you got all of it out. Now sit down, please." The motherly alicorn commanded.

Celestia plopped back down with a pout and glared at the mare, then she blinked as she wondered why she was listening to this weird alicorn, and why did she feel like she needed to?"

The timer gave a little chime just as Celestia tinkled a bit more.

"Oh, good filly! Now you can stand up!" The mare encouraged.

The princess got up slowly as the strange motherly alicorn came over and peeked into the potty. "Oh, such a big filly!" Then with a flick of her horn, all the contents were gone!

Celestia eyed this strange version of herself with disbelief and asked. "Who are you? Why do you look at me?"

The mare didn't respond, merely turning Celestia around and lifting the mare's tail as she explained. "I'm your mommy, Sun Butt! I don't look like you, it's the other way around."

The sun princess's face turned pink, having a feeling what the mare was going to do next. "Mommy? You're not my mom!"

The mare lifted Celestia's tail and took something from a pink diaper bag wrapped around her. "Oh, hush sweetheart now, please standstill."

"Seriously, who are you!? Are you ch-eep!" Celestia cried out, feeling the cold wipe hit her rump as the mare continued. "No, we're not changelings, dear. We're ponies like you."

"D...did you come through a mirror?" Celestia questioned whimpering now, getting worried.

The imposter chuckled under her breath. "Oh, that would be all too hard to explain to a little filly like yourself."

"Stop pa-pa..um...babying me! Not a foal!" Celestia shouted, now getting agitated. Then she squealed, suddenly having the pull-ups torn from her charge's legs and being plopped into her bathtub. This caused a big splash that sent a wall of pink, sudsy water out.

The princess squealed as the giant mare took out soaps and shampoos and went to work, scrubbing the suds into her mane and coat, then producing a scrub brush and going about scrubbing the mare's coat down, getting all over her body and in her crotch area.

The princess kicked and squirmed about as she was taken out of the bath and wrapped in a big, fluffy, pink towel. She was dried stunningly in mere moments and now smelt strongly of cake. The mare was wide awake now, and before she could protest, a toothbrush slathered in bubblegum flavored toothpaste was shoved in her mouth, and her teeth were then brushed.

"Alright, spit." The giant alicorn ordered.

"No! Nah, my mom!" Celestia cried out, her cheeks bloated with toothpaste and saliva.

"Spit or no pancakes!"

Celestia growled as she spat out the toothpaste and stomped about like a foal throwing a tantrum. "Ugh! Why ya doing?! Ugh stop!" The toothbrush was shoved in her mouth again and had them brushed once again.

"Spit!" The motherly alicorn ordered again.

"No! Not until you stop!" Celestia protested.

"You spit on the count of three." The imposter simply commanded.

"That won't work; I, not a baby!" Celestia shook her head.

Undeterred, the motherly alicorn commanded. "One!"

But Celestia stomped about and shouted. "Na...nah gonna!"

"Two!" The strange alicorn counted.

"Stop it, please!" Celestia pleaded.

"Thr-" The motherly alicorn mmphed, not wanting to spit. But she also didn't want to disappoint this mare and unwillingly spat the mix of toothpaste and spit into the sink.

"Good girl. Alright, just one more time." The motherly alicorn commanded, as the princess once again had her teeth brushed, a little less forceful on the third time.

"Alright, spit." The strange alicorn ordered.

Celestia spat out what toothpaste was left in her mouth, not even trying to even fight anymore. The mare then hoofed her a sippy cup full of water and cooed. "Come on, use this to swish about with what is left."

"I have regular cups! I dun wan a sippy cup!" Celestia whined.

"One!" The giant started to count again.

"Fine!" Celestia shouted as she took the sippy cup in her mouth, sucked a good amount of water and spat it out angrily.

"Good girl. Now come on, time to get you dressed." The mare hoofed Celestia back to the bedroom.

Celestia was surprised to see that her bedroom had been altered. Her bed now had rails, there was a closet full of dresses, and there was a calendar hanging by the bathroom with smiling sun and frowning stormy cloud stickers. She looked around the room, feeling as if she was in another world or having an odd dream.

The other Celestia took out a brush and went about combing and brushing her mane, then cooed. "Alright, go ahead and use your magic."

Celestia grunted and, with almost all her effort, set off the magic in her mane, making it sparkle into a lightly colored rainbow and flowing.

The mare took it into bunches, tying the mane into ponytails. The mare then placed Celestia on a strange table in her room. It had a padded pink foam top with a set of cabinets underneath.

Celestia's eyes lit up, remembering the conversation from earlier. She instantly started to kick and whine. "No, diapees! Dun need tem!"

The imposter just started counting once more. "One!"

"That's not gonna work this time!" Celestia protested and then shouted. "Lulu help! Guards! Maids! Twily! Anyone!"

A big yellow pacifier was plopped into Celestia's mouth a second later as the imposter chuckled. "Oh, so fussy this morning. You definitely need a nap later."

Celestia glared at this mare and tried to shoot magic out of her horn, but for some reason, only sparks shot out as if her magic was somehow reduced. Then, two guards suddenly burst into her room, and one asked. "Mam, is everything alright?!"

"Oh, yes, everything is fine. The little princess is just fussy this morning." The motherly alicorn casually explained.

Celestia wanted to shout, but she couldn't say anything. She kicked and cried out, but instead, "Mmph!" came out as she suckled on her pacifier, feeling completely helpless. It actually felt soothing to suckle it as it bobbed up and down in her mouth.

The other guard simply nodded. "Alright, we'll leave you to it." The two guards shrugged and slowly closed the door behind them as this odd alicorn used her magic to reveal a nicely folded up diaper with little smiling suns printed on the fabric. "Now, if you can manage not to use your diaper, you can be upgraded to pull-ups. However, the more you use your diapers, the more you're gonna be padded up. It's as simple as that."

Celestia's face turned a bright pink then noticed something else odd her cutie mark was now a smiling sun! "my cutie mark what is that!?"

"Oh, it's just your cutie mark." The motherly alicorn cooed. Celestia then simply looked away while suckling on her pacifier gently. She would've tried fighting back, but at this point, it was pointless, and she would rather just endure the embarrassment.

The strange alicorn then went about taking a hoof and gently rubbing a good amount of diaper cream over her charge's rump.

Celestia kicked and whined, feeling the cold cream as it was smeared over her most sensitive areas.

The mare took her time smoothing it out. The imposter then went about and applied a good amount of foal powder over the rump that made the true princess sneeze. The other Celestia continued to explain. "I know this is embarrassing, but you need diapers, or you'll be leaving puddles and messes all over the place. But like I said, if you can keep your pampers dry, I'll put you back in pull-ups."

Celestia wasn't even worried about being in a diaper at the moment. She was more stunned thinking about her guards, who just thought this was normal as if she was just a toddler who constantly had tantrums. The mare sighed, seeing that the only way out seemed to be for her to find Luna and hopefully get help. And in order to do that, she would have to endure some embarrassment.

The alicorn then went about and untaped the diaper before her. She lifted her charge's rump and slowly laid her butt on the soft padding. Celestia suckled on her pacifier to keep her calm, but she was not ready for the diaper to be folded gently over the front of her underbelly, the tapes being secured with magic. The giant then smoothed the tapes over with a hoof and gently led it down around her charge's thighs, making sure the leak guards were secure.

The diapered princess just watched and suckled on her pacifier, hoping it was over. But the embarrassment didn't stop there. Out came a butter yellow colored onesie with some cute white ruffles stitched around the crotch flaps. The pampered princess could only watch as her new nanny snapped the crotch flap over her underbody, the buttons starting to click in place, and her padding bulging around her bottom with some of the diaper fabric peeking through.

At last, Celestia was placed on the ground and was led out of the room by this weird version of herself. Then she noticed another oddity about her captor, her crotchboobs were huge! They were bulgy looking and were clearly full of milk with a thick coat of white fur covering them.

Celestia then looked around and turned her head, trying to talk to her staff. At first, they looked over with confused looks, and they seemed to try asking what was going on. But as the odd alicorn came over, they simply waved their hooves and asked. "How is the little cutie doing?"

The imposter would talk about "Celestia," commenting how she was quite fussy this morning and how she went potty like a big filly. The true princess tried to scream or shout for help, but the pacifier muffled any speech, and her voice came out as "mmphs!", and so she was carried off, unable to do anything. She couldn't use magic, and her wings were pressed against her body beneath the onesie.

The princess had no choice but to waddle to the kitchen where a booster seat was strapped up on the chair. Celestia squeaked as she was suddenly plopped down and strapped up, then a cute pink bib with "spoiled princess" written on it in silver letters was tied around her neck. She rolled her eyes as the mare went over to the kitchen to the stove to start making pancakes.

As the imposter made breakfast, the mare looked around, seeing staff walking around and going about their business. But they merely gave her a glance, and when they did, it was with a cute smile and coo "Good morning.", or something more embarrassing like "Aww! Such a cutie!" or "Oh? You ready for num num time?!"

As if she really was just a mindless foal! It became clear this imposter had an enchantment surrounding them that made other ponies seem to think she really was just a helpless foal that had to be cared for.

The alternate version of Celestia eventually came over with a pancake with a smiley face on top made of whip cream, strawberries for eyes, and syrup poured all over.

Celestia glared at this other version of herself as she removed her pacifier. She wasn't going to go down as the imposter tried to shove cut up pieces in her mouth. The princess shook her head, trying to avoid them. The pancake was mushed all over her face as a result. She refused to eat or give into any of this mare's demands until she told Celestia what is going on!

The nanny Celestia gave an annoyed sigh. "Oh, you're so grouchy. I definitely have to make sure you get a nap. But we don't have time. Your sister is coming back from her dream walking, and you need to be fed."

The motherly alicorn then took the tip of her wing and tickled the pampered Celestia's belly. She giggled and kicked about, and this allowed the nanny to go about floating the cut up pieces of pancake into Celestia's open mouth, and she regrettably munched on them.

Celestia's face went pink, realizing how good the pancake was. It was so so buttery and fluffy! It would've been delicious even without all those toppings, but with them, they were utterly delectable, rivaling her own! Celestia gulped it down and opened her mouth as more pieces of pancakes were shoved into her mouth. One by one, she munched on the pancakes and swallowed them down. It was such a great breakfast; she forgot all about being dressed like a foal. Then she saw the strange Celestia take a pancake and ate it herself. After swallowing it, she took out a foal bottle and opened it as she placed it under her belly, filling with some creamy breast milk. She the twisted an amber nipple over it and shook it about letting it froth with the creamy substance pouring out from the amber nipple.

Celestia watched nervously, scared at the prospect of drinking her own breast milk! But her other self then suddenly shoved the bottle into her mouth, and the pampered princess mpphed as the warm creamy milk went down her throat. Celestia closed her eyes, tasting the milk. It tasted so good, like pancakes melted into a buttery, smooth taste with a hint of syrup. She actually loved it and secretly was hoping she could suckle on it for a lot longer but squeaked as the bottle was suddenly removed from her mouth with a pop! She smacked her mouth and suddenly groaned, feeling the milk churn down into her stomach.

"Alright, time to burp the baby." The giant of an alicorn picked the princess up with her magic as she placed her over the shoulders and smacked her back until the real Celestia puked out a mess of milk and munched up pancake into a bucket behind her. The alicorn's mouth was then wiped with a handkerchief, and a yellow pacifier was promptly shoved into her mouth.

"Such a good foal, eating all your breakfast like a big filly!" The pampered princess was placed on the ground as the imposter continued. "Now come on, time for you to shine!" The giant took her by the hoof and led the blushing pampered princess outside to raise the sun!

Celestia's face turned a bright red as she suckled on her pacifier, even more, seeing all these eyes watching her in such an embarrassing outfit. Many dawwed, and some giggled while others simply snickered. The princess scrunched the diaper between her legs and squealed as the imposter raised a hoof. "Now now, it's time for little Sun Butt to raise the sun. Please be silent, this is the first time she's done this."

"No, it's not! I raise ta sun lots of times!" The pampered Celestia was able to shout through her pacifier, but suddenly squealed as she was lifted from the ground! The sudden gesture made her cry out and kick about in her crinkling diaper, placed into the hooves of her captor! The princess raised her wings out and flew into the sky. Celestia cried out, kicking about in her crinkling poofy diaper as she felt her gut sink. It really did feel like she was flying into the sky for the first time! She squeaked at this burst of fear and adrenaline and cried out, hearing an audible hiss emanate from her diaper!

They were now high above the clouds, and the pampered princess felt so scared, suddenly kicking and whimpering while sucking on her pacifier, trying to calm herself.

"Hush, it's ok. We're almost done, cutie," The imposter cooed. "Now raise your wings for me! Come on, you can do it, Sun Butt!"

The pampered Celestia did so, raising her legs out and spreading her wings as the sun slowly appeared in the clouds. The princess was so happy and proud of herself at first, but her face turned red as she felt a new wave of urine hit her diaper, causing her crotch area to warm up. As the two lowered to the ground, Celestia squeaked and cried, seeing her padding swell so much it caused the flaps around her onesie to open up, revealing her yellowed, soaked padding to the crowd below. The ponies snickered and laughed below at Celestia, peeing her diaper. She kicked and cried, being gently lowered as she stood there before all the nobles of Canterlot in a soggy diaper.

The giant unfolded wings and hugged her charge close to the other princess's furry chest. She rubbed her charge's head and cooed. "Oh, the poor baby. You couldn't help it," The imposter princess looked up and glared at the nobles as she shouted. "You should all be ashamed for laughing at the poor princess! Now please leave before I put you all in diapers too!" The nobles quickly dispersed as the nanny Celestia checked her charge's diaper yet again, squishing the sodden diaper, making the true Celestia feel even more squeamish. The mare cooed. "Oh, it's barely wet, don't be so embarrassed. Now come on, let's get you to your throne." The motherly alicorn explained to Celestia, who was then led through the castle and into the halls, waddling along with her soggy diaper apparent to everypony.

She then heard her sister, who exclaimed suddenly, "mama! Mama! I finish dream walking. It was lots of fun!"

Celestia was surprised upon seeing her sister wearing a cute purple onesie with a thick diaper strapped around her rump, her mane was tied in two pigtails while waddling up to the giant proudly. The motherly alicorn nuzzled her charge and pat he diapered rump, "oh Moon Butt so proud of you! But you're soaked and a little messy how about I change you!"

Luna giggled, pointing a hoof at Celestia. "Hehe, ya, a soggy baby too! So much for being ta big sissy!"

Celestia groaned, seeing her sister was completely brainwashed or under some enchantment. Luna turned to the motherly alicorn and babbled, "ya gonna change her diapee, huh?"

"Oh yes, I am and yours too," The motherly laid her charges down as a group of maids, butlers and guards suddenly came by. The princess cried out, but the pacifier again muffled her pleas and kicked a bit more, but the giant waved a hoof. "Oh, I'm glad you're here. Now come over, I'm gonna do a little lesson on how to change Sun Butt and Moon Butt's diapers."

To the princess's horror, she saw the mix of guards, butlers and maids all watching as the motherly alicorn started the change. The imposter first took her charge within her magic and laid her on a big, yellow foam mat that suddenly appeared. Celestia whined and kicked, trying to fight back, but she was powerless against this alicorn's power, having her legs spread apart as her captor started the lesson. "Now, first, we make sure the foal is comfortable, and you can tell she's agitated. The pacifier helps, but a stuffed animal can do wonders," The mare then took out two stuffed animals. "Now, I've got two of your favorites, which one do you want? Your plush bunny Hoppy, or your plush phoenix Phila?"

Celestia was embarrassed and confused, just wanting to get through this diaper change. She instantly took the plush phoenix and held it close to her chest. Luna raised her hooves and babbled," wan ta bunny!"

"Oh here you go Moon Butt." the princess hovered the plush bunny to the alicorn's hooves and the giant went about slowly untapping the padding, unfolding it outward for both princessses as she continued." Now, you can see this diaper isn't really that dirty, but you always make sure the foal wipes you use are heated so as to not freak the princess out and have her pee on you." The mare then took the old diaper, balled it up and tossed it into the diaper bag. She then took some heated wipes and cleaned Celestia's rump again, making the princess twitch about, but it was a lot nicer than the cold wipes used earlier. She looked over at Luna getting changed, but she just giggled and kicked about as she peed a little."

"Oh, watch out for the waterworks!" the giant laughed, making everypony around them snicker. Celestia could only hope that this wasn't real or that everypony forgets his ever happened.

Celestia looked around and groaned, seeing her staff had notebooks and were actually taking notes.

"Now you rub the cream in first," The imposter continued to explain. "Make sure to get her rump, it's quite sensitive if she's left in a soggy diaper for long periods of time. And make sure to apply a good amount of foal powder to make sure she doesn't get any nasty diaper rashes."

Celestia rolled her eyes as her staff seemed to nod their heads in agreement. She then suddenly squeaked, feeling the cold cream hit her rump once again, having it smeared all over her and Luna's underbelly. And then a good amount of foal powder was applied to both of their rumps.

"There, almost finished. Now for her new diaper," The alicorn took out a fresh, similar-looking diaper from the bag and showed it off to the crowd before her. "This is her favorite brand, the one with the smiling suns! They're all wetness indicators and are placed all over, so it should be obvious if she uses her diaper. It's also quite flexible. so it doesn't hinder her movement."

The giant took out another thick pamper with smiling crescent moons printed on the padding "this is Luna's favorite made by the same company their nighttime diapers designed to be thicker and more absorbent."

The crowd oohed and ahhed as if impressed with her diapers! One maid even whispered. "Oh, I must get those for my own foal. It's an excellent brand."

"If you hadn't realized yet, each of you received a diaper bag in the mail this morning with a full package," The imposter declared. "I expect you to all have them properly stocked and ready for use when you come to work tomorrow."

The staff soon dispersed, whispering amongst themselves. Despite the padding being embarrassing, though, even Celestia had to admit she secretly liked the diapers. They were somewhat cute looking, and comfortable.

The nanny princess then finished taping up the padding slowly and methodically around her charge's rump and completed the change. She then slowly buttoned up the hatch of her onesie and continued her lecture in an overly motherly tone of voice. "See? She's just like any foal, just bigger. And you always assure her that everything is ok and keep the foal engaged, so she doesn't feel a need to be scared or embarrassed."

Celestia got up with her eyes filled with tears and completely angry, frustrated, but worst off seeing her own sister, her only hope was now possessed with the strange magic.

The motherly alicorn simply picked Luna up and placed her on all fours then went about and adjusted the princess's onesie again, then cooed," now before you go to sleep, do you want something in your tummy?"

She nods as the giant turned around to show off her giant crotchboobs and luna latched onto one and started to suckle the milk down, making adorable suckling noises. Celestia watched, strangely enough, getting jealous. The giant alicorn turned her head towards Celestia looked behind her "Sun Butt if you want some go on the other teat is quite full."

Celestia smacked her lips seeing milk dripping from the other full teat she waddled over slowly being hypnotized by the luscious full breasts. She then slowly placed her mouth on one and slowly began to suckle on the warm fleshy teat and with each suckle a torrent of warm creamy breastmilk filled her mouth. Celestia eyes went wide as the milk tasted so much better then when it came from the bottle. The two princesses continue to nurse like foals for quite some time, then they both stopped with a sudden pop. The giant alicorn levitated Luna up and gave her back a few pats making the princess of the night puke. After wiping Luna's mouth the strange alicorn hoofed a maid over. "Alright, can you escort the little one to her bedroom and tuck her in?"

"Of course princess." the maid bowed and led Luna off down the halls making cute burping noises.

Celestia was then suddenly hoisted up and kicked and squeaked kicking about in her pampers. She was then bent over and her back was patted until she puked out, then the motherly alicorn "come on, let's get going."

The princess was led into the throne room; the guards lining the halls all waved a hoof as she sat on top of a massive throne and hoisted Celestia fight onto her lap with her pampers causing a massive cloud of foal powder to come out. The giant alicorn nuzzled her charge and boomed, "Alright,open the doors! Let's start the day court!"

The princess of the sun sat there on the throne as she babbled and kicked about in her padding. Many ponies came up to say hi to her as they discussed "big pony stuff" with her mommy but it didn't really matter to her because she felt so happy. She got less nervous about using her diaper, or her onesie opening up ,or playing with a rattle which she shook about happily. After what felt like hours she had giant bottle of her mommy's breastmilk plopped into her mouth! Celestia suckled on the bottle with a content look on her face being in a utter bliss as the milk filled her mouth as she slowly fell asleep.
