King Sombra was in tartarus. Being daawed at by the nanny, peeing and pooping in his diapers multiple times (the nanny refused to let him use the bathroom, saying he wasn’t old enough for potty training), not to mention being bottle-fed. What was worse is that he had scribbled a black crayon on a piece of paper and now it was hung over the nursey, pinned to a corkboard with a caption in red crayon that read: “Somby’s first drawing”
Sombra was on the floor in a fake coma coming to the realization that this was all real, while Discord was rolling on the floor laughing, “It wooks wike a piwe of woms.”
Nightmare Moon giggled, “Ya, it’s wike bwack spwgetti.”
Chrysalis was too busy stacking blocks to care, as Nanny Sunny Bright strode through the nursery doors with a giant pink foal buggy and cooed, “Oh Somby, Celestia has something special for you tonight.”
Sombra got up and asked, “Wha ya mean?”
All the other foals giggled as Discord whispered, “Ya gonna meet Mommy Cewestia.”
Sombra’s eyes went wide as Nanny Sunny Bright picked up Sombra and strapped him into the buggy and covered him with a foal blanket as she cooed, “Now are you comfy?”
Sombra sighed and nodded his head, the nanny then took the buggy through the nursery doors. He gulped as they strode through the hall and every time they past a guard they would chuckled, while the maids daawed at him and whispered amongst each other. The nanny then came upon Princess Celestia’s chamber and knocked on the door. She asked, “Your grace, little Somby is here.”
A sweet and motherly voice replied, “You can come in.”
The nanny opened the door and pushed the buggy through. inside the room a small play rug was on the floor with Princess Celestia sitting on it. Celestia was in a pink apron with a heart stitched into the center. She smiled. As Sombra noticed the rug had blocks and foals toys all over the place and a pink wastebasket and changing table in the back. There’s my Somby, place him right here.” she instructed, patting the rug to emphasize her point.
Nanny Sunny Bright blushed seeing her superior in such silly garments as she placed Sombra on the ground and left the two to check on the rest of the foals.
Kneeling down to the regressed former tyrant, Celestia cooed, “Now Somby you’re probably wondering why you’re here, right?” Sombra just nodded as she continued, “Well I’m your mother now and it’s my duty to play with you and try to get to know you like any good mother should do. My first and only rule right now, is that you call me mommy.”
Sombra eyes glared, “Ya tuwn me to a fowl, ya not my mommy! I swear on my dada’s gwave tat I wiw find a way to escape tis and get back to nowmal. And when I do, you in big twoubwe!”
Celestia sighed, as she took Sombra in her magic then nuzzled him. The former tyrant tried not to giggle as she then cooed, “For that, I’m going to find a way to make you laugh.” She proceeded to tickle him all over, using her hooves and even a feather from one of her wings, not letting up on the tickle torture, as Sombra started to burst out laughing. Inhaling deeply, Celestia finished it off with a raspberry that made the regressed king squeal in laughter. She then placed him on the ground near some blocks and giggled, “Now I heard you made a lovely drawing today.”
“Is jus scwibble.” Sombra muttered, furious at his newfound lack of coordination.
Celestia shook her head, “I disagree, I’m sure you have a very artistic mind. Now, how about you help me build a tower with these blocks?”
“This may be my chance, I’ll wait until she lowers her guard, then try to escape!” Sombra thought to himself, and reluctantly played with Celestia, using his stubby hooves to place a big wooden block over the one Celestia had placed. “So do you like blocks?” the alicorn asked, as she placed a block on top of the Sombra had laid down.
Sombra giggled, “Ya, I wove bwocks.” Then he gasped! “Why the buck did I say that?!” he thought
Celestia appeared to have a sly grin on her face as she continued, “That’s good.” Then she placed another block over the one Sombra placed.
Sombra was now angry, and would’ve clenched his teeth (if he had any). He stood up and prepared to smash the tower, but something in the back his mind told him it would be much more fun to see how tall the tower could get. “I’ll build it up nice and tall, then topple it over and make my escape while Celestia is distracted!” he thought, and carefully placed yet another block on the stack.
“Wow Somby, you’re very coordinated.” Celestia cooed.
Sombra looked up and asked, “Wha cowinate me?
Celestia smiled, “It means you’re very careful. You’re also behaving a lot better than your brother and sisters did when I first invited them to build blocks. Nightmare Moon didn’t want to build blocks with me at all, Discord kept trying to make the blocks come to life, and Chrysalis stuffed a block into her diaper and tried to run off with it. It’s nice to see you’re playing with me without any hassles, I hope you’ll keep up this good behavior.”
Sombra shook his head as he tried not to show how much he appreciated the praise he was getting from the same mare who had regressed him, “Something is wrong here, it must be some kind of spell. I’m King Sombra, Lord of The Crystal Empire! I won’t fall for this!” he thought, as he stacked his next block on top of the one Celestia placed.
“Oh, Somby, you’re doing such a great job!” Celestia encouraged.
Sombra beamed at the princess and asked, “How bi do ya thin we c-” then he stopped as he realized what he was going to say He shook his head again, as Celestia giggled and placed another block on top of his. On the inside he wanted to scream “Stop trying to turn me into a foal, you crazy mare! Or we’ll see how you like it, once I figure out how to get back to my regular age!” But instead, all he could do was cry.
As Sombra bawled, Celestia sighed, “Come on, Somby, we were having so much fun. What’s wrong?” But Sombra just bawled louder, so Celestia then took him into her hooves and cooed, “There there, Somby, Mommy is here,” she examined his diaper with a hoof, surprised at how damp it was. “My goodness, no wonder you were crying. We’d better get you cleaned up before you get a nasty rash.” Celestia said in a motherly tone of voice.
Sombra nuzzled his face into Celestia warm apron, that was radiating with a calming heat. She carried him to the changing table as he lipped, “I not we!”
Celestia smiled at the young colt, as she laid him on the changing table. This caused his diaper heavily filled with his own urine to squish up against him. “Oh, Somby, you soaked through it.” Celestia told him, all the while retrieving wipes, foal powder, rash cream, and a new diaper. She quickly stipped him of his soggy pink diaper and wiped his crotch and rump.
”Why ya doin thi mommy?” Sombra asked, before he gasped again, as Celestia just smiled “Okay, she’s using a spell! There’s no way I would ever call her mommy!” he thought.
In response to his question, Celestia told him “Because, little Somby, as of right now you and your siblings are under my watch, and I have to make sure you can live in Equestria like proper citizens. What kind of mother would I be if I didn’t play with you and change your diapers?” She then lowered his legs and started to apply the foal cream and powder, then she took a giant white diaper with a little sun pattern on it and lifted his legs again while threading his small tail through the back. She finished the diapering job by snuggle strapping the undergarment over his crotch. She then threw his soggy pink diaper into waste bin, as she lifted him up with her telekinesis and dawwed at him as he kicked his back legs. “Alright, I think it’s time for some num nums.” she said sweetly.
Sombra groaned, that meant he was going to bottle fed, but he soon found out that wouldn’t be the case. For right then and there, Celestia stripped herself of the apron and laid on her big bed. She then lifted Sombra near her underbelly, revealing two large, white, and very plump, teats. Sombra’s eyes went big “Woah? Didn’t expect her to have those!” he thought to himself, which only made his shrunken state all the more humiliating. Before he could do anything. however, Celestia used her telekinesis to shove him right into the first one, and as he latched on her nipple, he was rewarded with a squirt of creamy milk. He then clutched it and started to suckle, getting more milk for his efforts. In shock, he tried to pull away! “No! There’s no way I’m suckling her teats! I’d rather starve to death!” he thought, but he couldn’t stop what his foalsih mind was telling him. And right now, it was telling him to keep suckling the warm creamy milk. It was SO warm and SO creamy, and he wanted more!
Celestia smiled at her charge as he eagerly drank her milk and lightly cooed, “There, there Somby, not too fast.” using her wings to shield him from anyponies that should suddenly come bursting through the door.
Sombra groaned, he’d actually been reduced to a foal sucking milk from teats. “Dear Tartarus, what am I doing? Why am I enjoying this so much?” he angrily thought, yet he couldn’t stop himself from continuing to suckle. He reluctantly slowed down, lessening the suckling as his belly started to fill up. Soon, Celestia was humming a lullaby, and he felt his eyelids grow heavy. In a matter of moments, everything went dark as his eyes closed.
Sombra woke up under a warm pink foal blanket, noticing that the moon was high in the night sky. Everything was quiet, as he heard the snores from the bed. “This is my chance to get out of here!” he eagerly thought. He carefully crawled from his spot, seeing the floor below. Reluctantly he dropped down, and landed on his rump. His puffy diaper absorbed the impact, but it still startled him, and it took all his will power not to cry.
He looked up to see that Celestia was still sound asleep, good! He carefully began to crawl through the play room, taking care not to step on any toys, least he wake the princess.
Then the little colt came to the door, he looked up realizing that there was no way he could open it by himself. Then He looked around and smiled as he spotted the pink foal blanket he’d been sleeping in. Despite his chubby little hooves, he was able to grab the blanket, but it was too small! He then saw another blue blanket, tied the two together, and threw his makeshift rope at the door knob. It turned ever so slowly.
Almost immediately upon exiting the playroom, Sombra was hit by a most desperate urge to use the bathroom. Celestia’s milk had gone right through him. “Otay, I find a bathwoom fwist and make a quick twip to ta potty, then I get out of dis pwace.” he told himself, and set off on his search for the room with the porcelain throne (so what if he was small, he’d find a way to use it). He then crawled through the dark hallways of the castle, looking around and trying not to alert any of the guards, that seemed to busy talking to each other or chuckling about something. He felt tempted to crawl up to one of them and ask them where the nearest bathroom was, but he quickly ruled it out. “The instant I trot up to them, they’ll know I got out of bed and send me back. Curse my tiny body, if I weren’t so small I could kick their sorry butts easily.”
Sombra then looked down a dark hall, convinced he’d seen a light. Said light was two glowing eyes staring back at him, and something that called out, “Who is sneaking around this late at night? It would seem we have a prowler.”
Sombra freaked out! He wanted to crawl away, but his little limbs seemed to develop a mind of his own, as they became stuck to the ground! He wanted to cry, but only a small yelp came out. As the thing came closer he heard a faint hissing noise and then the voice asked, “Do I hear thy’s bladder leaking?”
Horrified, Sombra looked down and realized that his new diaper was becoming yellow and the little suns were fading. To make matters worse, he could feel a lump growing in the back, and that could only mean one thing! “Just great, whoever or whatever that thing was, it scared me so much I lost control of both my bodily functions. And I’ll bet the bathroom was just around the corner too!”
Then the identity of the voice stood over Sombra. It was an alicorn with a flowing purple mane and a coat as dark blue as the night sky. Casting her cyan eyes at Sombra, the mare cooed, “There’s nothing to fear Somby, Mama Luna is here to make everything better. And my goodness, just what has Mama Celestia been feeding you? Not since Nightmare Moon’s first time have we smelt such a horrible stench.”
Casting a spell to keep the horrible smell from reaching her nostrils, Luna lifted Sombra with her magic, as guards came rushing into the hall. “Princess Luna are you alright?” one of them asked, before his nostrils were assaulted with the horrible aroma coming from Sombra, prompting him to cast a spell on Sombra to keep his stench from wafting through the castle (and giving the poor little guy a clothespin so he wouldn’t have to suffer).
Luna smiled, “We’re fine, one of the foals was out of bed and we were simply escorting him back..”
The guards all flashed goofy smiles at Sombra, then as they began to trot away, they couldn’t keep themselves from laughing.
Humiliated and beaten once again, Sombra could only bawl as Luna hugged him and cooed, “Don’t cry, I’m here,” to the guards she bellowed out “Soldiers, retain thy military bearing! Hast thou no respect for a defenseless child?!”
The guards all stopped immediately and one replied, “Sorry, Princess Luna, it won’t happen again.”
Luna smiled “No it won’t, and for laughing at a poor foal, I think you all need to make up for it,” Her horn glowed and soon giant puffy blue diapers were strapped around the guards flanks. Luna giggled, and Sombra burst out laughing at the guards, who were blushing and trying to keep their bearing. Luna continued, “Now those diapers won’t be able to be removed until my sister raises the sun. so I suggest you take this as a warning, or I can make them stay on longer.”
With all the guards blushing, they just nodded. Then they went down the hall, grumbling all the way, with the crinkling echoing.
Luna cooed, “Now then, Somby, time for your change. Hold on tight.” And with that instruction, the princess of the night teleported herself and Sombra into her own bedroom. But Sombra had little time to take in the details, as he was laid on a soft blue changing table.
Luna’s horn lit up and Sombra diaper with suns was taken off and tossed unceremoniously into the trash. Luna magically sprinkled foal powder onto Sombra rump, as well as wiped him clean, then she strapped on a new diaper, this one dark blue with tiny silver moons.
Sombra groaned as he kicked it a bit and pouted, “Thos gwards deswv a wost punishment.”
Luna eyed him and told him, “Now Somby, I think having them wear diapers for a night is punishment enough. Besides you’re still in trouble for sneaking off like that Once I’ve disposed of your old diaper, I’m taking you back to my sister, and I know she won’t be pleased to hear you snuck out while she was asleep.“
Sombra gulped and started to quiver “Oh no, not another spanking!”
Sombra wailed as he received his fifth spank from Celestia, somehow her using her bare hoof hurt even worse than when the nanny did it.
“Now are you going to go sneaking off again?!” Princess Celestia asked sternly.
“No.” Sombra whimpered, rubbing his sore bottom.
“What did I say you’re supposed to call me?!” Celestia demanded
Sombra cried again, “No, Mommy, I won’t go sneaky off agwain.”
Satisfied with the answer, Celestia pulled up Sombra’s moon print diaper and sighed, “Thank you, Luna, for keeping him out of trouble.”
As Celestia was hugging Sombra, Luna smiled and whispered, “It was my pleasure. I was wondering how long it would be before he’d try to make an escape on his own. Nightmare Moon waited a whole week to try and nearly snuck past me, Discord didn’t bother for almost a month only to get caught when he tried to teleport past the first hall, and Chrysalis barely made it past the door after waiting for five days for her chance. From the looks of things, it seemed his destination was the bathroom just down the hall from my room. And Faust knows what could’ve happened had I not found him when I did.”
Celestia was a bit concerned by Luna’s statement, but she still cooed, “Well it looks like we’re going to need extra security from now on. And I have just the fitting solution in mind.” She smiled as her horn glowed brightly.
Sombra’s whimpered as his diaper was shining with Celestia’s magical glow, “Wha you doin?” he demanded.
Celestia giggled, “Just an extra precaution in case you decide to go sneaking off again. If you try it, you’ll be in for a very big surprise,” She then settled him near her as she cooed, “Alright Luna, I’ll take him from here.”
“Very well then, but I would suggest making sure somepony can keep an eye on him when we cannot. We may not be as lucky next time.” Luna warned, as reluctantly went back through the door.
Celestia sighed again “Alright, Somby, how about you sleep with me tonight?” She then slipped him back under her belly and cooed, “Besides, I still have one full teat left. See if you can’t fix that for me.”
Sombra then latched his little mouth around the teat and started to suckle methodically again. As he did so he thought “What if this is it? What if I actually start to act like a foal and forget all memories of my past life?”
