Luna returns

View Online

“Luna,” Celestia choked out. Her voice overflowed with relief, and she ran to her sister. Nightmare moon was finally gone, joy and hope bubbled up from the bottom of her heart. “You haven’t aged at all have you” she said softly. Celestia looked up and down at her sister’s tiny frame. She looked so young. Guilt knawed at her mind, she sent her to the moon so little...

Luna sat in place where the dust had settled, and looked up at Celestia. As she went to stand, she felt her legs wobble with fatigue. The fight with the holders of the elements of harmony had drained both her magic and her energy. Without the tantibus clouding her vision and mind, she was able to think clearly for the first time in ages. Her eyes widened as reality set in, “It’s been a thousand years....” She said softly. It’s been so long, what have I missed in all this time? Regret and sorrow slowly filled Luna’s heart. She wanted to wail, to cry, anything to release the horrible feelings of loss, but she forced herself to keep her composure, it wasn’t proper to show weakness, and she’d already made a fool of herself. Luna tried to hide the tears that had already welled up, and she grew red with shame at the thought about everything she had done, to her subjects, her friends, and most of all, her sister.

“Let us return home little sister.” Celestia said gently, breaking through Luna’s apprehension, a loving smile traced her cheeks, though her eyes betrayed a sadness behind them that Luna did not understand. She nodded, and Celestia gathered Luna's small wing in her own like they had done when they were little, “We have a lot to discuss.“

Luna hesitated, but followed her sister onto the chariot, reluctant to leave the Castle, the only home she’d ever known. She glanced at the other young ponies as the chariot rose, and saw their smiling, triumphant eyes. She couldn’t meet their gazes. Then, she turned to her sister, “I’m sorry…” Luna started, “for everything that happened...” her voice trailed off into silence as the words got caught in her throat, her mind filled with the foggy memories of an eternal night and the cruelty she inflicted while under the influence of Nightmare Moon. Celestia gave a shallow nod, but otherwise remained quiet, and tightened her grip on Luna’s wing. The air was cold and it blew through the sister’s manes as they flew, silently home.

When the mares arrived at the castle in Canterlot, Celestia helped Luna out of the chariot and led her inside, past rows of dumbfounded guards and astounded workers. Everything was quiet, aside from the clattering of their hooves in the corridor. Celestia took the lead and directed Luna through the winding halls, adorned with gold trim and beautiful pAintings. As the two walked, it was easy to see how a pony could get lost without a guide, and Luna felt grateful that Celestia was still keeping her safe, she seemed to know the way, like she always did, and that reassured her enough. Though she tried as they walked, Luna couldn’t seem to read her sister’s emotions, she felt distant. When they reached a dark blue door adorned with Luna’s cutie mark, Luna smiled, a bubble of happiness floating to the surface of guilt and shame that had been clouding her thoughts. It was a room built for her. Celestia had always meant for her to come home… The older mare opened it and led Luna in, locking the door behind them, and turning on the lights as they drew towards the center.

Luna looked around the room, feeling overwhelmed with joy and surprise. The walls and ceiling were painted a dark blue and had constellations and galaxies moving gently across them in intricate detail. Every star, and every galaxy was intimately designed one by one, as if someone had painstakingly drawn it to scale. The floor was a soft shag carpet in a pale blue, with speckles of different shades to show depth, and all of the furniture was dark mahogany, or panted midnight blue with silver accents. Luna smiled with wide eyes and began to tear up again, this room was everything she could have ever dreamed of and more. She turned to her sister and wanted to hug her, but if she was anything like the Celestia she knew, it wouldn’t be welcome. “It’s beautiful,” She said quietly trying to hide the quiver in her voice.

“I’m glad you think so,” Celestia said gently, looking at her with soft eyes. Her voice paused, and it was clear that she hesitated to continue. “Now though, it’s time to discuss the terms of your reform…” Celestia said slowly, reluctantly, as she stood over Luna. The younger mare seemed to falter and she looked up. Celestia sensed the burning tension, and felt a pang of guilt and apprehension. She knew Luna would hate what she’d have to do next, but she also knew it would be the best way to undo the damage that had already been done.

Luna paused, and her eyes now radiated confusion. The smile Celestia had when they arrived was weaker now, replaced with a look of gentle discomfort, and Luna became uneasy.

“I spent a thousand years on the moon sister, was that not enough?” She asked incredulously. Luna felt a wave of despair building in her chest and she felt suffocated.

“Unfortunately no…” Celestia explained in an awkward but firm voice, “Though it was an adequate punishment, punishments are valueless when not paired with reform,” she continued with a note of disappointment. “Your crimes caused so much havoc, and your mental state was so compromised that the only way I was able to convince Equestria to allow you to return at all was to swear upon a reform program. The purpose of which is to ensure that you remain well cared for, and loved so that those terrible string of events will never come to repeat themselves. Consider it as a cleansing of your heart and soul. Though, I expect you’ll resist at least to begin with...” Celestia explained, and with her discomfort and anxiety, she began to pace, circling Luna whose eyes grew wider with dread and anticipation. “…I’m sure eventually you’ll come to enjoy yourself regardless. It took me quite a while to figure out what kind of reform would be accepted by the court, and also be adequate to accomplish the intended goals, but I eventually settled on this. Your actions before and after the influence of Nightmare Moon were a result of jealousy, envy, and a lack of love. I neglected you before. Now, I will be better. We will re-live your childhood, better, happier, and more cared for.” Celestia’s gaze and tone radiated a mix of happiness, righteousness, regret, and hope for things to go smoothly.

Luna sat down as her world felt like it was falling away from her. She wished she could say that it didn’t make sense, but everything her sister said was crystal clear. “What do you mean, re-live my childhood...?” she asked quietly, not at all liking where this conversation was going, but knowing she was nearly powerless to stop it without starting another fight. Her hooves fidgeted with nervous energy, and her cheeks prickled with the damp remnants of her runaway tears.

Celestia watched the confusion and dread wash over Luna’s face and her heart felt heavy, despite coming to the same conclusion she had before. This would be good for her, it would help them bond, and Luna would forgive her for the embarrassment later. “Well, the biggest component of your reform is that you are to be diapered, and the rest we can leave for after your nap” Celestia said after a small pause. “Now, would probably be the best time to get started with that, so we’ll still have some time left in the evening.” She explained matter-of-factly, speaking quickly to avoid more incredulity.

Luna was dumbfounded. A diaper? She must be joking, it was ludicrous, and humiliating, and... Luna felt a sinking feeling in her chest. She sensed the righteous determination from her sister and knew it would be fruitless to try. Nonetheless she clung to the last remnants of her pride. “Sister you can’t be serious, I’m not a filly!” Luna argued as her voice raised slightly in volume and pitch. She stood up quickly but anxiety made her feel unsteady on her hooves.

Celestia’s smile died completely, and she looked at Luna with a moment of hesitation, and let out a small sigh. “Luna, this needs to happen. You’ll be alright, it’s just a diaper.” She countered taking a step towards Luna, her voice almost seemed irritated. Celestia didn’t really want to have a struggle but if it came to it she was prepared. “If you cooperate, this will be much easier.” Celestia’s horn began to glow as she summoned a large thick diaper, periwinkle blue and covered in stars, to the floor next to her. She looked at Luna with a pang of sadness and displeasure. Celestia felt bad, this wasn’t her first choice and she knew Luna would’ve wanted something else, but it was the best solution. She was determined to do what she knew was best for Luna, and determined to keep her sister safe and protected..

“I'm not a filly!” Luna shouted at her sister. The irony of her petulance was not lost on her, and her face grew red as she realized she sounded just like a disobedient foal. Luna’s eyes widened and her ears dropped, and when the diaper revealed itself she took a step back not sure where to go. She began glancing around for an exit, but she knew that she was unfamiliar with the building and it seemed like the only way out was the door she saw her sister lock only moments ago. “Please don’t do this Celestia, I’m perfectly fine going to the bathroom like normal.”

Celestia looked at her sister again and sighed her voice more firm. She felt more confident in her decision despite Luna’s reaction. “This is for the greater good. You’ll see, everything will be better this way,” Celestia’s voice was gentle and resigned but unwavering. Without much more than a flicker of light, a magic blocker appeared around the base of Luna’s horn, and her wings were securely pinned to her frame. “Now will you please cooperate so I don’t have to make this any more difficult?” She asked, clearly not thrilled with this turn of events, despite her commitment. Celestia had hoped, if in vain, that Luna would be reasonable with her, but it seemed to be that it was not to be.

Luna was blinded as she saw a flash and when it faded she felt restricted and to her dismay, her wings wouldn’t budge. When she tried to summon a spell to free herself, she realized with a second wave of dread that she couldn’t use her magic. Her anger and fear bubbled up as she struggled vainly against her sister’s magic. “This has been enough! I am not a filly, please treat me like a mare as I justly deserve.”

Celestia sighed. She wondered briefly for a moment, why her sister had to fight everything. It was for the best, she thought, as her soft coercion slowly evolved into force. “Difficult it is then.” She said with a resigned finality, and with a second flicker of light, Luna was laying on her back on the floor.

Luna felt her vision clear again and she felt the ground beneath her. She tried to move, but found herself tethered there by some magical means. She began to panic, feeling trapped, almost like when she was fully consumed by the tantibus, and she flailed as much as she could with her movement restricted.

“This will make things much easier,” Celestia said, a small smile briefly reappeared before fading. The idea of diapering her little sister brought both old memories and a sense of calm over the situation. She’d be lying if she said that this solution didn’t please her just a little, but it was also not because of it. Luna would see. “Now let’s get you changed.” She said pressing a hoof into Luna’s flank placing her in position.

Luna tried thrashing on her back, kicking at her restraints but she made almost no movement. “Don’t do this Celestia! I’ll show you I’m a good citizen, we don’t need to do this! Nightmare Moon is gone!!” Luna yelled, still trying to get out of this predicament. She was afraid and desperate, but Celestia showed no signs of giving in. She did, however, conjure up an oversized powder blue pacifier which she strapped to Luna’s muzzle muffling her protests. Celestia then lifted up Luna’s flanks, and laid the diaper underneath her. Luna felt something brush her bottom, and her tail weaved through the small hole in the back. She was then powdered, and taped into a much larger version of a foal’s nighttime diaper.

Celestia stood her sister up, and released her from the magical restraints. “That’s much better don’t you think?” She said putting on a soft motherly tone, she smiled sheepishly and went to embrace Luna who pulled away in anger. Celestia felt disappointed by the rejection and tried to brush it off, it was only reasonable for her sister to be a bit upset. No matter, she thought looking at her sister who felt so much younger now. Perhaps if she just dove in, Luna might accept things quicker. “Now is my little Lulu ready for nap time?” Celestia asked, using her sister’s old nickname, attempting to lighten the mood, she sent a bolt of magic towards the bed at the end of the room. Bars appeared all around it and the normal bed transformed into an oversized crib.

Luna kept her eyes on Celestia, but as her bed evolved, as he felt her eyes grow wide with shock and humiliation. She could feel her sister’s magic pick her up and she fought trying to escape it as Celestia lifted her up and into the crib. Luna tried to cry out with disbelief and upset, but only made out some unintelligible garble behind the pacifier. When she no longer felt her sister’s magic, she tried to jump back out however Celestia was one step ahead and had secured it with a magical barrier. Luna’s head bounced off it with a thud and she stared at her sister bewildered.

“Have a good nap Lulu, I’ll be back in a short while,” Celestia said before leaving the room and turning off the lights, hoping maybe this would help Luna get into the right headspace.

Luna seethed in the crib in her dark room. Thankfully it wasn’t pitch black, and gentle flickers of light beamed from the mural around her, bathing the room in a gentle glow, similar to a nightlight. How could Celestia do this, especially after what she’d already put me through?! Luna stood up in the crib and began to pace, thankfully it had enough space to do so, though she’d rather not be confined in the first place. In Luna’s mind she had to get out, and reason with her sister, it was the only way that anything would get done. Sure, Celestia might be acting a little unusual but maybe she wasn’t too far gone, and she could still reason with her. The mattress’ plastic cover crinkled in tandem with her diaper with each movement, and it frustrated her further, reminding her of her predicament. She pressed her hooves into the magic barrier above the crib and it held firm. Luna bent down and gave it a hard kick, which not only failed to damage it, but also sent a jolt of pain down her back left hoof. Luna sat down and cradled her sore hoof and snorted in frustration. The barrier was far too strong to break and she didn’t have the means to get out any other way except to wait.

If I'm going to have to stay put the least I can do is remove the stupid diaper. Luna thought to herself with disdain, slightly embarrassed that it wasn’t the first thing she thought of doing. As she began to try and rip off the tapes of the diaper that Celestia had put on her, she began to realize she couldn’t grab them properly. Luna broke into a cold sweat and dread began to rise up in stomach. She switched tactics, attempting to slide it off her hips. Pressing her hooves to the top of her diaper she began to push, only for her hooves to just slide off ineffectively, as if the diaper was covered in oil or another equally slick substance. It finally occurred to her, that Celestia likely enchanted it to prevent her from taking it off. With a wail of frustrated defeat, she collapsed on the mattress, face buried in the fluffy sheets.

Why is this happening? I was stuck on the Moon all alone with Nightmare Moon, taking her verbal harassment and mental cruelty for a thousand years, why is it that when I return, when I think maybe I could rest in peace, do I have to be subjected to this humiliation? Luna felt defeated once again, and now horribly alone. In her heart she knew there must be some rhyme or reason to Celestia’s plan but she just couldn’t believe it was the only way. There must have been better options than this.

Luna buried her head in her hooves, her emotions finally boiling over after a stressful and emotionally taxing day. Soon, she gave out a gentle whimper, that grew until she was sobbing and hiccuping into the bedsheets. After only a few minutes, Luna had cried herself to sleep.

Celestia shut the door to Luna’s room and reluctantly walked down the winding halls, hopeful but ultimately disappointed.

She’ll see the good in it eventually, Celestia thought in an attempt to reassure herself that she was doing what was best for Luna. Besides, this is what she needs after being alone for so long, a comforting hoof, and closeness.

Her hoofsteps grew louder the longer she continued to work herself up. Celestia knew part of this was also because she wanted to reconnect with Luna, do all the things she’d never done for her before. Luna would look so cute if only she’d just cooperate! she thought in frustrated angst. She eventually made her way to her own bedroom, a gold and white door between two guards. She dismissed them at the entrance with a nod, and she entered as they departed for a new assignment. When she closed the door, Celestia flopped onto her bed, tense and frustrated, feeling conflicted.

Celestia had finally managed to relax when a knock on the door gathered her attention and she narrowed her eyes.

"Come in." She called to the pony outside her room, unable to fully mask the irritation in her voice. Two guards entered, the one on the right had a silver coat, and the one on the left was dark grey.

"We believe Luna maybe attempting to escape." The silver stallion said quite matter-of-factly, his voice was mature and professional, but had a grandfatherly feeling about it, and any pony would guess he was nearing retirement. Celestia couldn't say she was surprised at the news, and she gave an exacerbated sigh. Why can’t Luna just see that this is what’s best for her! When she thought about it though Celestia had to admit she hadn’t expected Luna not to fuss, even if she’d hoped otherwise.

"That is to be expected. Let her be undisturbed she’s quite secure for now." Celestia said dismissing them from her room with a wave of her wing. Once they had left, she was once again alone with her thoughts. If Luna knew what Equestria was demanding I do to her when she came back she would understand. Being diapered was nothing compared to losing her wings and her horn permanently, then locking her in a dungeon for the remainder of her natural life. Ponies wanted blood… Celestia thought back for a moment , remembering the day Luna was sent to the moon.

"You never cared about me!" Luna shouted, spitting venom at her sister, her words filled with hurt, indignation and a cruel determination as the sky grew black before their eyes.
"I always loved you Luna! You just never noticed when I showed you!" Celestia shouted in return, summoning her magic to prepare the spell she hoped she would never have to cast.
"I did notice it, but that was never love! You treated me like your play-thing, it was never care or affection, it was control! In all this time I’ve tried to reach out to you, tried to gain your love, but you ignore me!" Luna wailed tearing up. In that moment of vulnerability, she felt the last of her slip away as Nightmare Moon took over her mind and body.

Celestia shook herself, the memories she looked back upon only brought sorrow. She sighed, This time I will make it right. I can show her a love like I never did before and also fulfill my expectations as a leader to keep her and others safe. When she was finished packing away her mental sorrows, Celestia moved to her desk and began to write, preparing the next step of her sister’s reformation.

Luna roused as Celestia lifted her out of the crib, and set her on the soft carpet of her room. As she came to her senses from her restless and unexpected nap, her anger and indignation flared up again, but she paused when she felt a nagging pressure in her bladder and bowels, which she hadn’t evacuated for much longer than she’d considered. She stared back at her sister, her eyes hard and unrelenting but still puffy from her pre-nap melt down.

"Did you sleep well Luna?" Celestia asked.

Luna ignored her, and kept her gaze hard and unmoving.

She removed the pacifier from Luna's muzzle and tied it around her neck as one would wear a necklace. To Celestia, the grumpy look on Luna's face was adorable and she couldn’t help but let out a small smile. She was simply precious!

Just as soon as it was removed from her jaws, Luna began to shout. “Celestia this is ridiculous let me out of these shenanigans at once!”

Celestia frowned. She hadn’t wanted to bring out the big guns, but she also didn’t really want to have to fight her for the rest of this reform. “Luna, if I were doing this purely to spite you, this would not be my first choice. Do you understand what happened when you left?” She asked staring directly into her sister's eyes revealing a sadness and layer of knowledge in them which had previously gone unnoticed.

Luna hesitated in surprise. She wasn’t expecting Celestia to even acknowledge what she had said, let alone try to reason with her. “N-no…” She said letting her guard down. She had always wondered, on the moon, what happened when she’d left, but the question had left her mind almost as soon as she’d returned.

Celestia took that as her cue to explain. “I had nearly every pony from all across Equestria at the castle gates demanding that I do things to you. Things that I refuse to repeat because of how vile and terrible they are.” She said. The way she spoke revealed a gravity that Luna hadn’t felt in a long time. “The only way I could save you from horrors I had yet to imagine, was to tell those ponies that I would never let something like that happen ever again, and to swear upon oath that I would redeem your life upon return. This is the only way that I was able to convince Equestria not to....” Celestia said trailing off as she tried to convey the seriousness of what might have happened, without scaring her. “...just... think about that when you fight me, because though you have to answer to me, I have to answer to them.” She finished, her voice much darker than before, a hidden warning veiled in their depths. She didn’t want to make Luna feel any more guilty, but she also knew that without context, she may never stop fighting her own reform. This was a small price to pay for compliance.

Luna was still, her mind trying to wrap itself around what she had just heard. What was Celestia not saying? What might have happened without her around? She gave a small shutter shoving the thought out of her head.

Celestia regained her positive demeanor and smiled at Luna once again. "This evening we're going to be taking a tour of the castle grounds, and I'm going to explain the remainder of the terms of your reform."

"As your older sister, it is my duty to make sure you grow up to be a responsible mare. I failed my job once before, and I don't intend to fail it now. You once accused me of not caring for you, and I want you to know, that is not true. From now on it is my job to love, care for, and help you, to go beyond our past and make room for our glorious future."

Luna's heart sunk like a rock. She knew immediately that Celestia was deadly serious about her being her foal. She wanted to argue, but knowing what could’ve become of her, she couldn’t bring herself to do much more than listen, at least for the moment. Besides, when Celestia set her mind on a righteous path, it was nearly impossible to sway her.

Luna started to fidget, frustration dread and apprehension nagged at her mind. She also felt her bladder screaming for attention again. She needed to go soon, and she wasn’t sure if she would last beyond her sister’s monologue. Luna tried to glance around discreetly attempting to avoid drawing her sister’s attention. She might be stuck in this strange new position but it didn’t mean that she was going to play the part.

Celestia for what it’s worth, didn't seem to notice her sister's change in behavior and continued explaining her new reform, "Now I should probably tell you what I’m expecting from you" She said, breaking into Luna’s thoughts. "If you like I can explain them to you, or I can leave you a copy to examine yourself before our tour." She said a scroll popping out of thin air by her head.

"I think I’ll read it thank you." Luna said curtly. She didnt want to do either, but at least if she read them she might be alone for a while. She needed to pee, and if Celestia left, she wouldn’t be able to stop her from finding the mare’s room. Now was her chance, she wasn’t going to squander it.

Celestia sighed with a nod and passed over the small scroll. It was clear that Celestia had hoped to explain them, but she relented. She figured that allowing Luna a few freedoms wouldn't be the end of the world, "Alright. Come to the courtroom once you've finished reading and we’ll begin the tour," she said curtly, and left trotting away down the winding halls towards what Luna assumed to be the courtroom.

She waited for her sister to disappear completely in eager anticipation. When Celestia’s hoofsteps faded away she bolted, out of her room and past the guards stationed at her doorway. Their eyes widened but they made no move to stop her as she left. Her bladder pulsed and burned more desperately, seeking release, the rhythmic movement of her trot only making her more desperate. It was only after reaching the hallway that it occurred to her that she might be seen. However, she only paused a moment, reasoning that it would be worse to have somepony see her in a wet diaper than a dry one. Luna opened each door in the hall frantically, one after another, not fully closing a majority of them in her search for a bathroom. When she finally did manage to find one, Luna was in dire straits. She darted inside and locked the door. She reached for the waistband of the diaper and pushed and tugged but it wouldn't budge. Luna became more frantic, and she tried to squeeze her hind legs together, but it only created more discomfort. She remembered what happened before her nap and despair filled her thoughts. She tried to continue to remove her padding but she ultimately stopped to focus and contain her bladder.

The battle was lost in a matter of minutes. Luna broke her concentration for just a moment when another pony knocked on the bathroom door. It started with a tiny spurt of pee, then another, and finally she lost control completely and she soaked her diaper. Luna felt utterly humiliated, but the feeling of relief was more powerful as it washed over her when she let go. The diaper around her waist now felt much thicker and when she moved it squished its warm contents against her, sending a small twinge of pleasure up her spine, only furthering her humiliation and disgust.

When Luna regained as much of her composure as she could, she exited the bathroom. With her diaper now drenched, her gait became more of a waddle as her legs were forced farther apart. She could still feel pressure in her bowels and she prayed that her sister might have mercy on her if she obliged her. Luna reluctantly skittered back to her room, following the trail of open doors to find the two guard ponies outside it. They didn't make a sound and avoided eye contact as she blushed and walked past them into her room. She was glad they didn’t say anything because she didn’t know if she could’ve handled it. Luna pulled out the list, but her cheeks still felt hot and red, knowing what the stallions must be thinking of her. She tried to dismiss the though, and she began to read...

You are to call me Mommy or Tia
You are a filly and fillies are diapered, you will be diapered constantly, and will be expected to use them for their intended purposes
I am the only pony who is allowed to change and dress you unless otherwise indicated
You must tell me when you are in need of a change, especially since your diaper is enchanted and I may not be able to tell by looking
If you leave the castle you must be fully dressed
Bedtime is 9 pm or earlier depending on your behavior
You may not be anywhere except your room without an escort, or me
If you fail to follow these rules you will be punished
I reserve the right to add or change rules as I see fit

Luna snorted in disgust and tossed the list to the floor. It's as if Celestia really thought she was a foal! She wanted to break something but she didnt want to cause even more trouble, and besides that, the only things she had to break were her own. When Luna opened her door again, her wet diaper made her immediately feel more self-conscious. She glanced at it to see the once bright white stars had turned into dark blue raindrops. Luna exited her room and looked to one of the guards, attempting to try and keep some semblance of her dignity.

"Will you please escort me to Celestia in the courtroom?" She asked, trying to seem more regal in posture, holding her emotions back like they were taught to as young mares.

The guard on her left shifted uncomfortably. The other stallion explained gently but firmly, "Unfortunately little one we don't know who you're talking about...." he explained, "Do you mean you want to see mommy?"

Luna’s humiliation and frustration welled up in her chest and her cheeks became hot, but she still stood her ground, trying not to let them see how it bothered her. Of course Celestia would tell the staff about her rules, it wouldn’t make sense not to. She held her head up even though she felt like she would die from humiliation. “Yes. You know what I mean..” she said curtly.

The two stallions nodded, and they started down the hallways, keeping their eyes straight and doing their duty diligently. As she walked, Luna felt her stomach cramp up slightly and her face went pale, she hoped with a mortifying realization that she would be able to hold everything until she could speak with Celestia.

Order in the Court

Both guards walked with Luna, one on either side of her small frame as they made their way to the courtroom through the winding and dizzying halls. Though they were close to her, Luna could feel the tension and uncomfortable feelings between their small posse. She had considered trying to slip away, but knew that her escorts attentiveness meant she wouldn’t be able to, at least not any time soon. Not that it would really solve her problem anyway, she thought with dread as her stomach gurgled again.

Luna felt another cramp in her gut and before she could process what she was doing, she had stopped in the middle of the hallway. Her legs quivered and her face felt hot, the strain of keeping control of herself was painful, stressful, and embarrassing. After a moment, she felt a small nudge from the dark grey guard on her right followed by an irritated groan, “Keep moving, or you'll make things worse for yourself.”

Luna tried to ignore his comment but sent him a scowl. Why couldn’t he see that she was struggling? It took her another minute to regain her composure, but to the guards' relief, she finally began down the hall once again, albeit slower, and more awkward than before.

Through the halls, the party passed other small groups, mostly staff, and Luna could hear them whisper as they walked by. Her face grew even more red and her ears fell, radiating heat. She tried not to make eye contact with anypony, and kept her head down low. When Luna felt another cramp beginning to form, she was glad to see they were finally in front of a large sets of doors, which she guessed was the courtroom.

Another wave of pressure and pain washed over Luna and she sat down quickly. Her diaper was cooling down and it felt clammy as it pressed into the fur on her flanks and her nether regions. She hated the feeling of it against her skin, cool and wet and squishy, another reminder of her failure. Despite the unpleasantness, she stayed seated, the counter pressure of her body on the floor helping her keep the remnants of control she had left as the cramps grew in frequency and intensity. Luna tapped her hooves on the tile impatiently. She hoped Celestia would meet them outside the doors, and that she wouldn’t have to get up, she was becoming more and more aware of the futility of her own losing battle. She glanced at her escorts from the corner of her eye, not really to make eye-contact but wanting to try and commit their faces to memory, in case she needed help later. They were kind enough and she didn’t want new escorts if she could help it, enough ponies had seen her like this already.

In that brief glance, Luna accidentally met the eyes of the older pony, whose gaze was warm and fatherly. The younger guard who sat on her left though, radiated impatience and anxiety, and gave her a small push forward. “Lulu… you don’t want to keep her waiting” he said, pressuring her to move.

Luna frowned and moved to stand, but it only took one shift of her haunches before she realized with fear and horror that if she didn’t stay seated she would completely lose control. Luna stayed still and the squish of her wet diaper reminded her again of her previous accident. The memory filled her with determination to get a grip and keep things under control. Her sister had already made her wet herself, but she would NOT mess herself too if she had anything to say about it. She was not a foal, and she was going to prove it.

The guard on her left gave her a second nudge, more forceful this time and it was clear how impatient he was becoming. "Please, Luna.” He urged quietly, “Just get up, it's not that far.”

Luna wanted to shout at him, explain to him that it wasn’t her fault, that she couldn’t move without soiling herself, but that would be admitting defeat, and she didn’t think that she could do that without another blow to the last remnants of her pride. It was one thing to be stuck like this, but something completely different to have to admit what was about to happen.

Luna considered how to try and explain her obstinance in the least explicit way possible, when the guard on her left lost his patience with her. He moved behind her quickly and gave her a hard shove, pushing her bottom off the floor. The unexpected shove caught Luna off guard and as she lifted off the ground, her forehooves slipped, and her face smashed into the tile floor. She tried to right herself, to stop what she could feel was happening, but it was too late, the floor was too slick, and she had crossed the point of no return.

Without the help of the floor beneath her, Luna’s tail lifted of its own accord. Her stomach cramped for the last time and she felt her bowels release her mess into the back of her diaper. The relief from the cramping pressure and horror at what she’d just done overwhelmed Luna, so she didn’t notice when the doors to the court open. To anyone who noticed, she was quite the sight to see, bottom in the air, face down filling her diapers like a little filly. Luna gave an involuntary grunt, and if she hadn’t already been beet red, she certainly was now. Once the deed was done, she looked up to see Celestia standing directly in front of her, looking on with an expression Luna couldn’t decipher, a witness to her most recent humiliation.

The guards one either side of Luna stood at attention, and Luna slowly stood up on wobbly legs. She could feel the hot mass pressing against her bottom inside the now slightly sagging and squishy diaper. At that moment, Luna expected Celestia to give some snide remark, gloat, make fun of her, maybe even change her in front of her new guards/escorts, but instead, she walked up with a small smile on her face and embraced her.

“Ah, Lulu! I see you’ve made it here safely! Guards, you’re dismissed.” Celestia said, her tone was gentle and comforting, and she looked over Luna, making sure she was safe and well looked after. The young guard took off as if a gunshot had rung out beside him, and his partner followed slowly and rolled his eyes at their dramatic exit, leaving Luna all alone with her sister.

Luna stood very still. The mess in her diaper had become incredibly unpleasant very quickly. She felt like a naughty filly who had messed her new clothes, she’d have to do the walk of shame to the bathroom to get cleaned up, only there was no cleanup for her. Not yet.

What are you waiting for? Luna asked her sister in her mind, both disgusted and humiliated by her situation. It was only a moment before she remembered the rules, and realized Celestia was going to make her ask to be cleaned. Luna almost shook her head. No way. She thought, she would never ask to have her diaper changed. Celestia was just going to miss out on that indignity.

Satisfied with her examination Celestia called, “Follow me!” cheerily as she walked around the outside of the courtroom. Luna followed her, her excitement for a castle tour soured by the soft messy feeling in her diaper. Every movement pushed more of the mess onto her skin and she wondered if any amount of cleaning would be able to get the smell out. It was pleasantly surprising though, that the smell was entirely contained, not a whiff escaped, whether it was good thing or a bad thing had yet to be determined.

This is going to be a long afternoon.

A reo hours into their tour Luna was terribly bored and unfathomably uncomfortable. She considered for just a moment that maybe it would be better just to ask Celestia for a change; she felt cold and clammy, and the diaper felt heavy on her hips and itchy on her flanks. Celestia, however, seemed to be having the time of her life, pointing out which rooms each diplomat stayed in when they were there and what each other room was intended for. The tour continued on for another four hours, and by the time it was over Luna’s flanks burned and ached like she’d never experienced before. As they walked, she tried to give herself some relief from the pain and the friction by stopping for a few seconds before trotting to catch up. This immediately caught Celestia’s attention, and when Luna met her sister’s gaze she seemed confused.

I'm not going to ask. Luna thought to herself, though her bravado had been waning by the minute and it seemed more like she was trying to convince herself of her own decision rather than asserting it to her sister.

When Luna saw the look in Celestia’s eyes, she began to walk again. She held back a squeak of pain with each step. Celestia sighed, and turned away, praying that Luna wasn’t planning anything. She continued onward towards the kitchen where they had visited near the beginning of the tour, and when they entered, they were greeted by a light blue stallion with a blonde mane. "Good evening! Wonderful to see you again, are we all ready for supper?” He asked with a smile. He gestured to the dining room, and Luna assumed he must be the chef, like his hat and cookie cutie mark would imply.

“That depends, is everything prepared?” Celestia asked, her voice sounded more stern than it had been all day, and Luna paused to focus more closely on the two of them. She wondered with a bit of worry what her sister might have had in store for her.

“Of course!” The paisley stallion said with a small bow in Celestia’s direction. He seemed to ignore Luna though she was standing right beside her sister.

Luna looked him over and decided to ask him, just to alleviate her curiosity, “What's for-“ she began, when she was abruptly cut off by Celestia.

“You’ll see when it is given to you.” Celestia said quickly before walking her to the dining room entrance. The pause in the kitchen had been nice and when they began to walk again, Luna felt the intense fire rise up again from her tender and raw flanks. She was about to give up and ask Celestia to change her, when she saw the dining room.

Next to where Celestia presumably sat was a mare sized high chair, emblazoned with her cutie mark in a mahogany matching the furniture in her room. Luna stopped in her tracks, she was angry, humiliated, tired, and in pain. All of these feelings she battled finally boiled over and she could feel the first of her tears well up in her eyes. Luna planted her hooves against the floor and glared daggers at her sister.

When Celestia heard Luna stop, she turned around to see what had happened. “Come on Lulu, its time for dinner.” She said with a note of confusion and impatience, before she noticed the anger coming off her sister in waves, and the tears starting to roll down her cheeks. To say she was surprised would be disingenuous, but Celestia wasn’t expecting quite as powerful a reaction, especially with how well behaved Luna had been all day so far.

Luna stood her ground and shouted, “NO.” Her voice seemed to waver slightly, as her feelings took over. She was experiencing a rollercoaster of emotions, each one fighting for the spotlight. Pain, anger, frustration, indignation, and more, contributed to her mental anguish and it became the perfect storm for a tantrum.

Celestia took a moment to process what she had just heard, and what she was seeing. Luna had defied her, and not only that, she had defied her like she would expect a naughty child rather than her frustrated younger sister. Celestia frowned. If she’s finally decided to play along then two can tango... She thought. Looking at Luna in this state though pulled at her heartstrings. She looked so sad and alone, and though Celestia knew she had to make a point, all she really wanted to do was hug her.

We will hug later, but this needs to be addressed now. “What did you just say?” Celestia asked, less of a question and more of a challenge.

Luna’s blood ran cold, and she knew immediately that she’d made a mistake. Celestia’s face was stern and she watched as she walked up to her. Luna continued to stand her ground, though her legs began to shake with regret and the last fleeting shreds of her confidence. Her tears were now trickling down her cheeks, falling into a puddle at her hooves.

“I s-said no…I’m not going to eat f-from a high chair.” Her voice shook as much as she did, and she stumbled on her words through her tears and sniffles.

“I’m going to give you the opportunity to go sit down right now. If you choose not to, I will spank you.” Celestia said clearly with warning in her voice, giving Luna one final chance to back down. She desperately wanted Luna to take the easy way out, but she knew it was unlikely.

Luna was in way too deep to back down now, but she regretted it all the same. Celestia shouldn’t be making her do this, why did she have to do this to her? Luna’s confidence had disappeared so quickly, all she could do now was stay put, frozen in place, realizing how vulnerable her position was. Even if she’d wanted to give up now, she wasn’t sure she could will herself to move.

“I see we’re going to have to have some behavioral correction before dinner,” Celestia said with resignation in her voice. She saw the despair in her sister’s eyes and her heart broke. She didnt want to be the bad guy, but she had to show Luna that she was not to be disobeyed. Before Luna had a chance to run, Celestia pulled her over with her magic and turned her around in the air, exposing her diapered rump. Luna felt cold as fear washed over her and her sniffles turned to muffled hiccups as she cried. A paddle appeared behind her, her cutie mark painted on both sides of the paddle.

Luna’s already sore bottom ached as she was twisted, and when she saw the paddle she broke down completely, “P-please Celestia d-don’t! I’ll s-sit in the high c-chair, just please d-don’t!” she wailed. She wished in her heart that she’d just done as she’d been asked and as the paddle loomed over her, she dreaded the pain which was creeping up on the horizon. She tried to struggle against her sisters magic but couldn’t even manage a small wiggle.

“It’s Mommy, and I warned you what would happen if you continued to defy me, let this be a lesson you not forget” Celestia said firmly, steeling herself from Luna’s heart wrenching apology, before bringing down the paddle onto Luna’s diapered rump. The paddle connected with a small thwap, which was surprisingly gentle, really only spanking more as a show than intending to actually hurt her. The pain Luna felt on her flanks was excruciating though as the paddle, the diaper and her mess pressed against her raw bottom despite the gentle nature of the whack. Luna let out another cry, and Celestia summoned a pacifier to place in Luna’s mouth, silencing her.

“One.”

The paddle came down a second time, and Luna bit down on her pacifier, tears streaming down her face unencumbered as she whimpered.

“Two.”

When Celestia brought the paddle down a third time, she put in a little extra oomph, connecting slightly harder than the previous two but still quite tame. If Luna’d not gotten a rash, the experience would’ve been humiliating for sure, but not painful. Luna began to let out long hard shaking sobs and she begged Celestia to stop in unintelligible whimpers through her pacifier.

Celestia was befuddled, and she disappeared the paddle quickly and brought Luna into her arms and on her lap in an embrace. She had been so gentle, why was this the thing that upset Luna the most? Seeing her sister so distraught crushed her resolve completely, and Luna sobbed into Celestia’s coat holding her close as the pain slowly began to dissipate. The two sat on the floor of the dining room like this for a long while, Celestia rocked her sister gently until her sobs turned into hiccups, which then turned to sniffles. Celestia cooed softly whispering small words of love to her little sister as Luna began to pull herself together.

The two were quiet, and when Luna had finally calmed down after ten or so minutes, Celestia moved to lift her up and set her in the high chair. Luna’s flanks still throbbed under her diaper, and she quickly said, “Tia, please change me!” in shameless desperation to end the pain of her bottom. To Luna’s surprise, Celestia didn’t laugh, or mock her, she just nodded, and lay her down on the floor beside the table.

Luna’s flanks, unsurprisingly, were red and raw with diaper rash, and it clicked why she had taken the spanking so poorly. Celestia felt terribly guilty for not realizing how messy her sister had gotten, not expecting her to sit through the mess this quietly. She was careful to clean off every bit before adding diaper rash cream and foal powder gently on Luna’s raw skin, diapering her back up.

Celestia made quick work with her magic and her eyes were sad, which Luna had not expected. She was beginning to wonder why Celestia decided on this project, since she didnt seem to enjoy humiliating her, or making her miserable like she’d expected.

Once cleaned up, Celestia placed Luna in the high chair and took her own seat at the table. Behind them, the sky blue pony arrived with tray of food. He set a plate of cut up zap apple jam and peanut butter sandwiches in front of Luna and a bowl of vegetable soup for Celestia. They ate together quietly, and when Celestia looked up at Luna again, she let out a small giggle.

Luna for all her strengths was not used to using only her hooves and no magic. The jam in her sandwich had dripped out of it and was everywhere, not to mention the snot and tear streaks all over her face. When she heard Celestia giggle, she blushed noticing just how messy she’d gotten. Celestia took a wet washcloth from the table beside her and gently wiped Luna's face, chest, and hooves, cleaning her up. Luna looked up at her sister, expecting a smirk, but got instead a smile filled with love, which made her feel less ashamed.

After they’d finished dinner, Celestia lifted Luna out of the High chair before teleporting them back to Luna’s room.

Both mares were emotionally drained and exhausted. If Luna had been less tired, she might have fought Celestia as she placed her in the crib, however, the day had worn her out and she sat complacently instead, opting to deal with the rest in the morning, when she had more fight in her.

Luna was hoisted up and set in her crib, but when Celestia went to seal it with magic, Luna asked quickly, “please leave it open…” Her eyes were soft and puffy from earlier, and they hid no nefarious intent.

Celestia looked at Luna and considered saying no. She didn’t need Luna running off, trying to get out of the castle or make mischief where she didn’t need it, but when she looked into Luna’s sad, wide, and exhausted eyes, her heart melted. “Alright Lulu.”

Luna smiled with relief, and her eyes began to droop. Her body slumped into the mattress of the crib and she drifted off to Celestia singing quietly as she tucked her sister in…

There's a wee babymoon,
Laying on it’s back,
With its funny little toes in the air,
And its’s all alone,
In the big blue sky,
But the wee baby moon doesn’t care,
Babymoon, Keep shinin’ on me babymoon

Luna’s eyes shot open. Darkness enveloped her and she sat up in confusion. She wasn’t laying on the crinkly mattress anymore, instead the floor below her was cold concrete, and she was no longer wearing a diaper. She would have normally been relieved to be free of the childish garment, however she felt the air spark with tension which made her uneasy.

Where am I? What’s going on?

Luna thought to herself for a few minutes. When she tried to stand, her head collided with thick metal bars, her head and the metal making a nice crack sound in the silence of the room and eliciting a short yell from the pain. Luna sat back down rubbing her head where she had hit it. She reached out her hooves on either side, finding more rungs, and her uneasiness turned into fear as she realized that she was trapped in a very secure cage.

She tried summoning her magic but came to the conclusion that she still wore the magic blocker, and when she tried to extend her wings, that they were now tightly bound. She strained her ears and her eyes searching for anything that might explain what was going on, any stimulus at all. In the distance she could hear hoofsteps. She listened longer and realized that they were approaching. Before Luna had a chance to fully comprehend what was happening, the lights in the room were turned on, blinding her with their unexpected brilliance.

When she opened her eyes again, her heart went into overdrive. All around the room were strange evil looking tools, all in pristine stainless steel. Each had its purpose, some unknown to her, however she did recognize the bone saw, the hammer, and the assortment of nails on each wall. There were pliers, hooks, and more, some devices looking more sinister than others. The floor too seemed pristine, however upon further examination, faint stains splattered on the concrete of what substance she only could hope was innocent. She looked at the doorway in the corner of the room, hoping to find more explanation there, only to see her sister in a strangely amber inferno.

Luna sat up with joy, whatever was happening Celestia would surely get her out of it, free her from whatever had brought her here. She just about began to greet her with relief, but when they made eye contact, Luna’s stomach dropped. Her sisters eyes were cold and full of malice, nothing like what she had seen before she fell asleep. She scooted backwards but was stopped by the cage bars. “W-what’s going on?? Celestia What is this??” Luna asked with a shaky voice.

“Well it turns out the ponies of Equestria changed their mind” Celestia said with a smirk. “They want you to feel the pain that they did when their crops withered and their children starved. They want you to feel the torturous pain of losing a child, or a limb.” Celestia sneered as she walked up to the cage which Luna was trapped in. “And after you made my life so terrible, I’ve decided to join them. Yesterday was a joke, something to give you a sense of hope, this is your real punishment.” She said, giving her younger sister a toothy evil grin.

Luna’s eyes grew wide and he shook with fear. She knew that look. It was the look she gave Celestia when Nightmare had stolen her away, except Celestia still looked like Celestia, albeit more fiery. “P-please don’t hurt me Tia... I’m so sorry for what I did, I won’t fight you anymore, just let’s go back to before..” she said stammering, reverting back to the nickname she used to call her sister when they were younger.

“Go back?” Celestia said with an incredulous tone, standing straight up, her posture domineering, making Luna feel tiny in her presence. She tipped her head back and cackled, “No Luna you had your chance to be a good girl and you were a very naughty filly, now it’s my turn to get back at you for everything you did to me and Equestria. How could you think that after all you did that there was any chance I’d still love you?” She said her gaze uncaring and filled with unbridled cruelty.

Luna tried to scrunch herself up tightly, “Please no! I don’t want to! Please don’t hurt me I’ll be good! I’ll be a good filly!” She whimpered eyes filled with terror. She’d never seen her sister like this, she’d never been cruel. Even when they fought discord or when they had to kill Sombra she was always sad or reluctant to do unnecessary harm.

When Celestia turned to the wall, Luna grabbed the walls of the cage she was in and tried to force it open frantically. The cage didn’t so much as budge and Luna snapped to attention, with her heart racing when Celestia began to speak.

“Ah this’ll do. Tell me sister, have you ever wondered what it’s like to lose your teeth?” She said wielding a large pair of pliers menacingly.

Lunas began to cry. All she could do was look at the pliers in her sisters control, and beg her not to use them. In the back of her head Luna felt her bladder give way in fear, coating her legs and flanks in the musky scent. She wanted to flee, to move but she couldn’t no matter how hard she tried, and she felt more powerless than she’d ever been before. When Celestia took Luna in her magic and began to force her jaws open, she tried to struggle but the magic held fast. She was bawling now and as she felt the pliers grab onto the first tooth.....

Luna woke up. She was hyperventilating and crying and screaming nonsense as she tried to reason with herself, fear making her mind foggy.

It was only a minute or two after that, that Celestia appeared next to her sister’s crib, asking her what was wrong and if she was ok, seeming frantic, her own heart pumping as she wondered what was wrong.

Luna only continued to cry and when Celestia tried to touch her she shrank away her rambling becoming more audible. “P-please Tia d-dont pull out my t-teeth! I’ll be a good f-filly, I’m s-sorry I’ll never b-be naughty again!” She said to her, eyes squeezed tightly shut and obviously distraught. Her mind reeled, still stuck in the powerful emotions of her nightmare.

Celestia’s heart dropped like a rock seeing her sister in such fear and anguish. She lifted her up in her magic, to Luna’s dismay, causing another bought of confused pleading. Celestia pulled Luna into her arms and cooed softly keeping her close. “It’s ok Lulu it was just a nightmare, you’re alright, I’m not gonna hurt you” She said softly, her hoof petting her sister’s mane.

Luna eventually came out of the fear haze and buried herself deeply into Celestia’s hooves, who welcomed it holding her sister tightly and whispering phrases of love and reassurance to her.

The two of them stayed like that for nearly an hour, just holding each other until Luna’s bawling turned into sniffling and she seemed to be holding her own. When Celestia loosened her hold a moment she noticed that Luna’s diaper was soaked, whether from her nightmare or her subsequent break down it didn’t matter. Without hesitation, Celestia laid Luna down and quickly cleaned her up, making sure to treat her rash which seemed to be clearing up quickly.

As she began to lift Luna to go back into the crib Luna panicked, “No please Tia, don’t leave me alone please!” She begged eyes wide and puffy.

Seeing her sister in such a state broke Celestia’s heart and she brought her sister close to her in another embrace, as they left Luna’s room to finish the night in Celestia’s bed.

The Art of Diplomacy

View Online

Celestia groaned and flopped over on her bed, wing extending to smack the alarm clock beeping on her nightstand. She was tired, from yesterday’s tour and Luna’s Nightmare. She lay there, motionless and tried to fall back asleep. Just as her eyes began to droop again she bolted up.

“The meeting!” She cried teleporting herself out of bed as she frantically began to get ready for the day’s events.

Luna groaned, still laying on the other side of the bed, disturbed by her sister’s bustle. She opened her eyes just a crack to see Celestia blinking around the room only spending a moment in each spot before teleporting somewhere completely different.

Luna yawned and sat up, “What’s going on?” She asked rubbing her eyes to clear her vision and her head. She too was tired from the night before and she shuttered at the memory before pushing it out of her head.

“Im supposed to be meeting with a diplomat from Saddle Arabia!” Celestia said quickly, brushing out her mane. When she looked at the clock again she sighted with relief, her body relaxing immediately, and her pace slowed. Luna stared at her funny for a moment and when they made eye contact Celestia gave a sheepish grin and said, “I misread the clock...”

Luna giggled and gave another big yawn, before hopping out of bed. Her diaper crinkled but upon inspection it was clearly still dry from last nights change. She wanted to be embarrassed but with only her and Celestia, and she was far to tired to care about the diaper she wore. Luna paced in the room, bored. She had no duties or obligations and it frustrated her, eventually eliciting a snort. Celestia looked up, hearing her sister’s repetitive hoofsteps. “Oh Luna, you have two choices today.” She called from the bathroom, remembering that her sister hadn’t been briefed about the day’s goings on.

Luna’s eats perked up and she stopped pacing. “About what?” She asked, not sure whether or not she she should feel happy that her sister was giving up some of her control, or concerned about what those choices might be.

“Because I have a meeting, you will either have to come with me and behave yourself, or I can have you sent to school for the afternoon where you can learn and be around other fillies.” Celestia said returning her focus to her preparations.

School or public humiliation. Luna sighed, not really wanting to choose either option, however she knew that if she didn’t make up her mind that Celestia would surely decide for her. She hadn’t met anyone from Saddle Arabia, perhaps it was because when she was last in equestria the city was a mere settlement, though now she assumed it must be quite large to require its own diplomats.

Luna sat down in thought. If she went to see the diplomat, she would be still diapered but maybe she could pretend like it was a medical condition? But if she didn’t, and she went to school, Celestia could make sure that nobody breathed a word of this to anyone. She gave a frustrated sigh. None of these were good options.

“If I go with you do I still have to be dressed up?” She asked with a shred of hope still in her mind.

Celestia pokes her head out, mid makeup. “Of course you do silly filly. Other ponies are going to see you anyways, so why don’t you just make up your mind sweetie.” She said lovingly though a hint of frustration about her sister’s indecision was audible.

Luna sighed and thought about her options. If i’m gonna be seen either way, it may as well be by someone I already want to meet. “I think I’m gonna go with you Tia.” Luna said softly, resuming her pacing.

“Alright then. That means you need to be patient while I get you dressed”

Dressed? Luna thought, wondering why she couldn’t just be like she was. Celestia finished up her makeup, coming out of the bathroom looking like her normal stunning self. She lifted up her sister with a ray of magic, and within a matter of moments Luna was completely dressed.

She was quite the sight to be held when Celestia was done with her. Over her diaper she wore a light blue onesie dotted with cartoon stars and moons. On top of this, she wore a cute pleated skirt in a shade of navy blue, which did nearly nothing to hide the obvious bulge of Luna’s thick diaper. Around her neck, Luna wore her pacifier, though it was a bit larger than before.

Luna looked at herself feeling the clothing as it gripped her body. She blushed bright red and looked at her sister, her gaze a mixture of horror and humiliation. “I can’t go see a diplomat dressed like this!” She cried starting to tug at her new outfit. To her frustration it seemed to be under the same enchantment that her diaper was under, and none of her tugs even misaligned her clothing.

“Of course you can, and you will” Celestia said in response, a smile creeping up her lips, she pulled Luna closer and began to pull her mane into piggy tales. “Besides, nobody will think twice about you if you can play your part.” She said mischievously.

Luna stopped fidgeting to comprehend what her sister was implying. Celestia wanted her to act like a foal! “Even if I act like a foal, it’s not like anyone will be convinced!” She cried out in indignation. “I’m too big! I don’t even look like a filly, even less a foal!”

Celestia tsked. “Oh relax Lulu, Saddle Arabia was just beginning when we were young, they don’t know you or your tales, and they certainly don’t know much about alicorns. Who’s going to tell them that Alicorns age from adolescence just as quickly as normal ponies?” Celestia explained her voice filled with confidence. “You see, I don’t see why they would have any suspicion that you weren’t just a little foal in a big body.” She said mischievously.

Luna stared at her sister, mouth agape. Celestia wasn’t serious, she couldn’t be. There was no way they’d be convinced. Or would they? Her sister was right, even on the day she was sent to the moon, Saddle Arabia was merely a blip on the radar of even the most interested pony. Why then did she feel like her heart was going to jump out of her chest.

“Afterwards, can we spend the day inside?” Luna ventured, wondering if she’d have to try and keep up the act all day, or if there was some relief.

Celestia smiled, victory reflected in her gaze. “If you manage to convince our honored guest that you’re my little filly then we can do whatever you’d like when we return, provided that it abides by the rules I’ve given you.” She said confidently.

The walk to the Café which Celestia had arranged her meeting at was short, and because it was quite early, Luna found it easy to hide under her sister’s shadow. In the café, Celestia broke away from Luna to speak with the owner, and Luna took a spot underneath a table, avoiding eye contact with everyone she could. When Celestia returned to the table that Luna had arbitrarily chosen, she held a small play mat and a bin of toys, which she sat in the open space on the other side of the table.

Luna blushed red when she saw the mat and she skirted the edge of the table to sit down as close to the table as she could without leaving the designated ‘playplace’. In the back of her mind, Luna wondered why the shop seemed so empty. Celestia was so popular, yet there were no other customers. She dismissed the thought, and rifled through the toys, seeing her options.

In the bin Luna found blocks, stuffed ponies, teethers, toy carriages, a coloring book and a small box of mostly broken crayons. Deciding that it was the least childish activity of her options, Luna grabbed the coloring book and crayons.

Celestia watched her sister color for a bit, when she heard the door open and she sat up a little straighter. Luna, still coloring, almost didn’t notice when the dark grey Unicorn entered the shop, and she realized with a twinge of fear that her coloring had been just a little too neat and she switched pages, scribbling aimlessly, and avoiding eye contact. Her heart raced and she shrank back, and when the diplomat sat across from Celestia, she tried to look busy, like she had better things to do, foal things.

“Greetings Prince Slate, you look stronger than when we last met.” Celestia said with a polite smile.

Slate looked at Celestia. His mane was a dark grey and his eyes were a pale blue. He wore a scarf around his neck and each hoof was adorned with silver bands, almost like cuffs.

“The same to you.” He said with a nod, and sent a glance in Luna’s direction. “I see you have a friend.”

Luna’s heart stopped. A Prince. Was. The Diplomat. Why had her sister not said that before?! And friend? Did he know she wasn’t a foal, or worse, did he think they were dating and she was into it?! Luna broke into a cold sweat and though she desperately wanted to look over she pretended to ignore them, pulling out the blocks and stacking them haphazardly, their shoddy construction and Luna’s shaking hooves causing them to topple quite easily.

“Yes, I have a close friend who asked me to watch her daughter today, don’t mind her though she’s very well behaved.” Celestia said dismissively, “Now, let’s discuss the terms of our arrangement.”

Slate glanced once again in Luna’s direction and decided he’d ask questions later. Turning back to Celestia he nodded, “agreed.”

Luna had originally intended to pay attention to her sister’s conversation, but as she pretended to play, she became less and less interested. Eventually, her pretend play began to turn into genuine enthusiasm as she focused on the dolls, making them talk to one another in low grumpy voices.

It was when her purple doll Shell told her Boyfriend that she no longer loved him that Luna felt a twinge in her bladder. She paused her play and cursed herself for not trying to go at the castle where they’d be all alone. She ignored it and continued to play to herself but it was less enthusiastic the nagging not leaving her mind.

After another hour Luna was struggling to hold onto her bladder, and her bowels ached. She couldn’t concentrate on playing and when she glanced up, she knew that Celestia could sense her predicament. Only after she heard Slate say, “is she alright, she looks uncomfortable?” Did she realize with mortifying clarity that if she didn’t want to blow her cover she was going to have to use her diaper in front of another pony, and act like she didn’t care.

Luna kept her eyes averted and tried to pee, her forehooves shaking slightly, however her toilet training hadn’t relinquished it’s hold on her just yet and she fought for a good five minutes. When she finally got a stream going however, there was no holding back, and Luna flooded her diaper. The relief on her face was obvious, and her cheeks flushed even more when she heard Slate and Celestia turn to see what was going on, only to resume their conversation after they knew there was nothing wrong.

Luna continued to play with her dolls, the squishy diaper underneath her growing cold and uncomfortable. She wondered to herself if maybe it would’ve been better to just go to a dumb class, it wasn’t as if she got to meet the diplomat or anything. He was far too interested in her sister, and for that Luna was quite relieved under the circumstances.

It was only a few more minutes later that she felt her bowels ache worse and with disappointment, she realized that Celestia wasn’t even close to finished with her meeting. She gave a frustrated sigh and started to wiggle a bit, adjusting her position to try and relieve the pressure. She didn’t want to have to mess herself in front of Prince Slate, but she also didn’t see an alternative. She could try and ask Celestia but then she’d give herself away, and the same would happen if she tried to hold it too long.

The internal battle of choices Luna face must’ve screwed up her face and she felt Celestia tap her shoulder. Luna’s head swiveled to face her and she hoped that her thoughts hadn’t given her away.

“Would you like something to eat Lulu?” Celestia asked softly, both her and Slate looking at her with concern.

Luna’s face grew beet red and she did everything to avoid looking at the Prince above her. She gave a very small nod, her stomach giving a groan at the mention of food and she stared at the floor.

Celestia nodded and a bottle appeared on the table. Celestia sprinkled a little powder in the bottle before setting it down, and turning back to Prince Slate.

Luna stared at the bottle almost like she didn’t know what it was. She felt Celestia nudge her with a hoof and she knew that Slate must be watching. She didn’t want to drink it, it was humiliating, but if she didn’t she was sure their guest would begin to suspect something was amiss.

With a barely concealed reluctance Luna grabbed the bottle with her hooves, and tried to drink. The glass was slick and once or twice she was sure she’d drop it. It took a few suckles before the milk came, but when it did, Luna tasted the sweetness of the strawberry mix that her sister added and sighed.

Through trial and error, Luna manuvered herself to a position so she could more easily drink, craning her neck had gotten painful relatively quickly. She lay on her back, and smiled with success as the bottle began to drain much quicker, the sweet milk filling her stomach quickly. When it was empty, it vanished and left Luna laying surprised on the ground.

It was only a few minutes after that when Luna felt the pressure growing worse. She had no good options and she strained a moment longer only delaying the inevitable. When she felt like her groans and twitches were drawing more attention, she gave up. It would only make her more conspicuous to hold it, she said trying to convince herself that she wasn’t in fact giving in to Celestia’s foalish image. She turned over and bent down, finding it a bit easier to relax. It was a matter of seconds before she felt another wave of pressure and this time Luna stopped herself from holding back, she lifted her tail and with a soft grunt she pushed the heavy mess into the back of her diaper. She pushed onward, determined to only have to make one mess and it felt like forever before the flow ended. The onesie pressed her diaper directly onto her bottom, not allowing it to sag away from her like it did when she was touring and she grimaced lightly.

There was no smell to her mess, and she wondered if maybe Celestia had something to do with it. When she looked up, it didn’t seem like either pony had noticed what she had done. Luna wasn’t sure if she should be happy about that or not, the sticky mess clinging to her fur and causing a not exactly unpleasant feeling in her rump. She wanted to stand but even though she was short she would easily poke above the table height and call the unwanted attention directly to herself.

Her decision was made for her as she felt a bit of magic pushing her bottom down. Luna lost her balance in her forward lean and fell directly on her squishy bottom, spreading her mess all throughout the diaper. She wanted to gag, or glare at Celestia, but that would certainly give her away. Instead she turned her attention back to her to try and ignore her growing discomfort.

Celestia would insist later that the meeting only took three hours but to Luna, sitting on the edge of humiliation and fear it felt like ten. When the meeting concluded, Celestia gathered up the toys and returned them to the owner of the Café. Slate, who had previously been focused on Celestia turned his attention to Luna, sitting anxiously below the table.

When Luna realized he was getting closer she tried to act like she didn’t notice, however his hooves wrapped around her chest and lifted her up. He was much stronger than his sleek frame would let on. The implication of what was going on froze Luna to the spot as she was turned to and caressed by the prince.

“You’re such a cute little thing aren’t you.” He said cooing to her softly. He patted her head and held her close in his arms, though she was quite a bit bigger than a foal he still managed to make her feel small. “I’m sorry I didn’t get to play with you, you were the cutest playing down there.” He continued in babytalk as he gave her Eskimo kissses with his nose.

Celestia interrupted Luna’s unwanted cuddle fest with a short cough. Prince Slate, frantically put Luna down, not wanting to see a competitor in the market see his softer side. He cleared his throat. “I should probably be going.” He said quickly. “There’s still much to do after our arrangement” and with that he bolted out the doors, his own cheeks nearly matching Luna’s in a deep shade of crimson. It wasn’t much longer, that Luna and Celestia also took their leave, although Luna was much more sheepish, and giving a small limp as they walked out of the doors to the carriage which awaited for them.

To Build a Fort

The ride back to the Castle was uncomfortable. Luna felt her mess clinging to her flanks beginning to itch, and she thought maybe she should just ask to change. Just this one time of course. When she looked at her sister though, she was reminded of why that was not an option.

Celestia was looking at her tenderly, a bit of playfulness also in her gaze, "I see you and Slate seemed to get along." she said stifling a giggle. Luna's cheeks reddened and she averted her gaze. She was thoroughly humiliated and if they weren't within earshot of the guards outside the carriage she'd have given her sister an earful a long time ago.

"I'm surprised at you Lulu," She went on, smiling happily, "you did such a good job performing back there that I was even beginning to wonder if you were starting to enjoy yourself."

Luna faced her sister quickly, her anger finally boiling over and she roared, "I was most certainly not!" when the red curtain of rage faded from her mind, Luna saw her sister's hurt expression, and wished she'd just stayed quiet. Averting her eyes once again to the world of ponies outside she thought to herself about the day’s meeting. She had hated it! She wasn't a filly and she shouldn’t have been treated like one! Although, Luna had to admit it was kind of nice to be able to relax, and maybe playing wasn't as boring as she had thought, and- NO! Luna thought to herself pushing her thoughts back. None of this was fun! she wasn't going to enjoy it. Her gaze hardened out the window, as they made their way back home.

When the carriage finally halted, Luna had calmed down significantly, and rather than fuming she was now counting how many ponies of each color she could see on the street. When she stood the once itchy feeling on her flanks was beginning to be a light burning and she wished that she could ignore the tug of her pride and just ask her sister for the much-needed change. She refused to ask or even look at her sister when the doors were opened by their guards, as her own stubbornness was still winning over the pain on her flanks.

As soon as Luna crossed the threshold of the castle entrance, she felt something prod her bottom sending a wave of pain down her spine, making her flinch. Before she could twist around and complain, she was teleported to her room, and Celestia who stood behind her lifted her up into the air then laid her down in what Luna was beginning to recognize as the changing position. When she opened her mouth to question her sister with indignation especially with her flanks burning like they were, Celestia shoved in the pacifier that was hanging about her neck and kept it there securely with magic.

"Hrmng!" Luna mumbled behind the plastic.

"Just stay quiet while I talk to you," Celestia said curtly, “ when Luna finally made eye contact she could see how hurt her sister had felt from the look in her eyes. She stayed quiet, but her own gaze had not softened. "I'm changing the rules, Luna."

Luna's heart sank and she feared the worst. Was her sister so mad at her outburst that she wouldn't let her leave? Would she make her stay silent and trapped in her room for eternity?

"You've been hurting yourself by refusing to tell me when you need a change," Celestia explained with a quiet almost resigned tone. "So instead I'm going to have to check you, or ask if you're dirty, and if you're not honest with me I'm going to spank you. Am I clear?" Celestia asked as she began to remove the thoroughly used diaper attached to Luna's waist.

Luna felt relief wash over her. She wasn't going to be banished or trapped, and although she knew it would be slightly more humiliating, it would mean she wouldn't have to admit defeat or lose more pride. Luna nodded to her sister and felt a little ashamed at worrying her. Though she wasn't going to let her see that. Luna did admit she was hurting herself, and she imagined that it couldn't be making things any easier.

Just as Luna finished her thought, a new one hit her like a brick and her heart sank heavy with guilt. Celestia wasn't trying to make her miserable, at least not completely. She was really trying to make a change, to try and love her. This realization only caused her to avert her eyes. Luna felt both terrible for her actions but also indignant, she knew Celestia was trying to love her, and she loved her sister in return, but she also hated everything about what was happening. Though, she wondered if maybe that was true. Was she hating everything? Of course! The diapers and the outfits were terrible, and she felt humiliated constantly! However when Luna thought harder about it, the coloring wasn't so bad, and she did enjoy it when Celestia was hugging her. Even when Slate was cuddling her, sure she was embarrassed but it wasn't so bad, right? Celestia never hugged or cuddled her before she was banished and Luna remembered a time, far back, when she looked at other fillies with jealousy when their sisters hugged them, and she wondered if maybe just maybe she could begin to appreciate what was happening, if just a small bit for the sake of her sister.

When Celestia finished the changing process, Luna was still feeling conflicted, her gaze and mind focused elsewhere. She snapped back to the situation at hand when the pacifier was taken from her mouth and she was lifted back to standing.

The sisters looked at one another for a few seconds, silence building the tension between them. Celestia was the first to break it. "You did a good job today Lulu, and our agreement still stands. What would you like to do tonight?" she asked, glancing at a clock not too far away from them.

Luna's eyes widened as she too remembered their arrangement from this morning. It wasn't very late, only about 4:30 that evening, and she began to think of something she believed Celestia might be willing to do with her that wasn't totally foal-like. "How about some movies?" Luna tried. "Not filly ones either, something good," she said quickly.

Celestia considered for a moment. "As long as its PG-13, I think it could be arranged" she finally conceded. "Is that all you'd like to do Lulu?" she asked planning the timeline of their evening.

Luna shook her head. "No just movies." she responded and her eyes brightened, "Oh! We also need snacks!" she declared her mood improving as she pushed the complicated thoughts to the back of her mind to deal with at a different time.

Celestia called outside the room and an older looking guard arrived, her eyes were softer but held an unknown darkness that hadn't been ther before they left the cafe. "Please take little Lulu here to the film library and let her choose some movies for tonight's marathon. Three or four should be adequate." She instructed, and he nodded. "When the two of you are done, please meet me in the lounge." Celestia directed. With that, she disappeared, and Luna was led out of the room carefully by her guard.

Celestia appeared in the lounge and, with Luna now occupied, broke down on the couch, her anguish from the previous hour finally sputtering to the surface. Her quiet sobs made her body shutter and it was a minute or two before she could regain her composure. Luna hated her she was sure of it, she hated her and there was nothing that she could do about it. Celestia thought back to the nightmare last night. Luna pushed her away, she thought she was going to hurt her. Luna couldn't stand her and though she wanted so desperately to help her sister become a better pony. In this self-concerned batch of self-loathing Celestia was convinced nothing she could do would make Luna love her after everything that passed between them and she knew that the only pony to blame was herself. A knock at the door made her frantically regain her composure. When she thought that she was as prepared as she was going to get, she opened the door. To her relief, the pony behind it was only another guard and not her sister, and she let him in quickly. "Featherwing, what can I do for you?" she asked, a small sniffle escaping her eyes still quite red and puffy.

"You requested my assistance upon your return." He said eyes solid and determined, although concern for the princess's wellbeing was not well hidden in his eyes.

Celestia paused and remembered vaguely that she had in fact asked for his help, although for what she couldn't remember. She shrugged and blew her nose quickly which had begun to drip, "I see, well since you're here please help me get the room ready for a movie night. I need the following snacks and supplies..." she said as she turned her focus away from self-pity and back to the matter at hand.

Luna groaned again. "You don't have to check every movie I suggest!" she said at her guard frustratedly who was examining the rating on her most recent proposal.

"I have to make sure the movies are PG-13 miss or we may as well not pick them at all," he said ignoring Luna's whining.

"You can't seriously believe that The Little Mer-mare is a rated R movie do you?" she said exasperatedly before throwing up a hoof. It was the same with every movie she picked. She'd choose, he'd grab it, and then spend ten minutes trying to find the rating. It was beginning to get annoying.

"It doesn't matter what I think little one, I have a duty to perform."

Luna groaned and flopped on her back in frustration, the poofy outfit and her diaper breaking her fall quite easily to her dissatisfaction. So far she'd chosen The Little Mer-mare, It's a Wonderful Life, and The Griffon King and was starting to debate whether or not she could live with just three movies when she thought of the perfect last movie, Ender's Game! she stood up and searched the collection to see if they had it, her diaper causing her to waddle and eliciting a small smile on the older guard's face. Luna seemed oblivious of this in her mission however and she gave a shout of success when she pulled it from the shelf and laid the final movie in front of her escort. When he nodded and continued to stare at the movie he was on she rolled her eyes and sat in impatience ready to get on with movie night.

When Luna and her escort had finally decided on the movies that they were to watch, they made their way to the lounge. Luna sighed, relieved to be finally done waiting for her escort’s movie inspection, whose name she eventually found out was Silver Streak. Though Luna was still dressed up like a filly, she felt far less embarrassed about her situation. Maybe it was because Silver seemed to ignore it, or maybe she was just beginning to get used to her outfit, but she felt a bit less self-conscious.

When they arrived at the lounge, Luna began to feel more excited. She really did want to watch some movies, she hadn’t for so long, and spending time with her sister would be fun, she hoped. The door opened before she had a chance to even knock as if some mare was watching them.

Celestia stood in the doorway, and behind her, Luna could see a table full of her favorite snacks and treats. Luna’s eyes widened in excitement. She trotted inside, her sister closing the door behind them, and she could clearly see the rest of the room. The seating she had assumed would just be the lounge was actually transformed into a young child’s dream. The whole room was draped in blankets and cloth forming an intricate and beautiful fort, the door to which was small and towards the left of the snacks.

Luna let out a small squeak of excitement and bounced on each of her feet before looking to Celestia for permission to go inside.

Celestia smiles at her sister, her mood lifting at the happiness radiating from her sister, and though her mind was filled with negativity she pushed it back and chose to focus on the joy of what they were doing then. “Well, aren’t you going to go in?” She said with a small laugh.

Luna didn’t need to be asked twice and she bolted inside, crawling along the blankets that formed the floor of the blanket fort. She had always loved forts, especially when they were very young because she was always appreciated when she made them, and it was something Celestia liked to do with her. Everything was soft and colorful inside, and surprisingly well coordinated. She might have forgotten about the movies entirely if she hadn’t glanced to the side and seen the giant projection set up, where the room seemed to open up.

Celestia watched Luna disappear with the movies perched on her back and smiled, heading to the table to grab her own snacks. “Would you like me to bring you snacks Luna or are you going to come out and get them yourself?” She called as she fixed up her plate.

Luna paused and lay down in a place that she deemed perfect. “You can do it.” She said, not wanting to lose her spot.

Celestia rolled her eyes but began to get Luna a plate ready, yet instead of a cup, she fixed up Luna’s drink in a bottle. When everything was ready, she lifted the plates in her magic and crawled inside the fort, sitting near Luna, and placing the food next to her. Luna looked at it eagerly but, became confused when no drink seemed near.

“Let me know when you’re thirsty and I’ll get you something," Celestia said keeping the bottle out of both sight and mind.

Luna shrugged and began to dig in when she pushed the movies over to Celestia. “The Little Mer-mare first.” Celestia nodded and set up the player. When the movie began, she flicked off the lights with her magic, and felt Luna lay down beside her, Luna's body pressing next to her own. It reminded her of when they were much younger and Luna would stay in their forts all day, only coming out when she had to for food or attention.

The first movie went off without a hitch and they snuggled next to one another enjoying the movie. It was about ten minutes into the second movie that Luna felt a bit thirsty and she looked to Celestia, about to ask for the drink she had previously mentioned.

As if she could read her mind, which Luna wasn't totally sure was impossible at this point, Celestia pulled out the bottle from earlier and before her sister could speak a word, held it to her lips. Bewildered, Luna began to push away, turning her muzzle, movie temporarily forgotten.

“What are you doing?!” She asked trying to get away from the soft nipple without fully getting up.

“It’s just a bottle Luna,” Celestia said holding it out, her voice was stern and motherly “you had one earlier today,” She said, hoping that her sister would just relax and let things happen.

Luna frowned, almost angry. “That was only because I had to, Slate would’ve found out I wasn't really a foal if I didn't.” She said frustratedly.

“And you have to now,” Celestia said with an air of finality.

Luna’s mouth fell open and she glared at her sister before turning back to her previous position. “Fine, then I’m not thirsty.”

Celestia sighed and dropped the issue, her sadness creeping into her mind, and she wondered if it would be so bad to pull back on the punishment. When the thought entered her mind, she dismissed it. This punishment wasn’t for her, it was for Luna’s well-being and the ponies of Equestria. Parents cannot always be their children’s friend, no matter how much it hurts.

Near the end of the second movie, Luna felt parched, her tongue dry. She wanted a drink badly and thought about her options. She couldn’t leave, and couldn’t sneak a drink. It was going to be drink with Celestia, or not at all. She sighed and her shoulders drooped before she flipped over and moved next to her sister.

“I think I’m ready for the apple juice...” she said softly, not wanting to meet Celestia’s eyes.

The sudden request caught Celestia off guard, nevertheless, she quickly smiled and pulled Luna into her lap where her mood seemed to improve dramatically. When the bottle was lifted to Luna’s lips, she took it reluctantly, and after the first suck, she became much more relaxed.

The thirst which had been plaguing Luna for most of the second movie washed away and she would have almost smiled if her mouth hadn’t been otherwise occupied. The two of them sat there, in that small embrace for a few minutes, Luna looked at the ceiling of their fort and her sister’s mane while Celestia studied her sister’s face as if to examine her thoughts and feelings through her skin.

When the bottle was emptied, Celestia gently laid Luna on the ground next to her and gave her cheek a small kiss.

The next few hours went much the same, they would snack and cuddle, and when Luna would need a drink, Celestia would feed her a bottle. During the third movie, Luna felt the need to pee, however rather than miss the movie by distracting herself or begging her sister to let her go to the bathroom like she knew would be forbidden, she resigned herself to using her diaper, which gave her a comfy warm feeling that she hadn’t really considered before.

At the end of the last movie the two of them were both full of snacks and exhausted, the time was nearly 1 am, much later than intended. Luna was practically asleep on her hooves as she walked out of the room guided by Celestia.

She changed Luna who by then was quite wet and so tired that any complaints were long forgotten, and removed her outfit. She was laid in her crib, where she fell asleep nearly immediately. Celestia smiled and watched her sleeping sister, so cute and peaceful, before a yawn of her own dragged her to her own bedroom where she collapsed in her room sleep gripping her tightly, and tearing her away from reality.

Abandonment Issues

When Luna opened her eyes she found herself in the center of a bustling courtyard sitting beside Celestia. The sky was grey and the air was cold, a few snowflakes trickled down landing on her fur. She was still wearing her bed clothes from when she’d fallen asleep and a chill quickly crept into her bones from the cold cobblestones beneath her. Luna looked up at Celestia; they both were the only ponies sitting perfectly still, as wave after wave of bustling city ponies were making their daily rounds, seeming to ignore them.

Luna felt small next to her sister from where she sat on the ground, and just as she was about to ask where they were and what was going on, Celestia stood with an emotionless gaze and began to walk slowly into the crowd. Luna attempted to follow her but felt bound to the ground, trapped in her seated position.

“Tia wait!” She called to her sister as panic began to bubble up from her chest. The more she tried to move, the less she was able to make her legs budge.

Celestia made no indication that she had heard Luna’s cry, as she continued to walk into the crowd, silent and stoic.

The wind began to pick up and Luna tried to keep her eyes on her sister, as she struggled to stand. She became desperate and quickly lost sight of her. As soon as she did, whatever was keeping her down let up, and she bolted in the direction Celestia had gone.

“Tia, Tia! Where are you?!” She called into the ocean of ponies whipping her head from side to side. Her panic quickly grew into an overwhelming fear that she would never find her sister again. Luna ran and ran all over the cobblestone path, and she could no longer see buildings anywhere just an endless swath of ponies.

She stopped and begged ponies to help her, but each one continued on their path as if she did not exist.

Her fear and panic grew and Luna felt like she was shrinking, getting smaller and smaller unable to find help and unable to escape the empty loneliness and fear.

Celestia woke, hearing muffled cries from down the hall. Though she was still drowsy, hearing the distress which could only be coming from her sister sobered her from her fog of sleep. She lit her horn and climbed out of bed quickly, and traversed the dark hallway quietly as to not wake anyone else who’d managed to sleep through the whimpering cries of her sister.

Once inside Luna’s room, Celestia closed the door and moved to her sister’s side. She was still crying and whimpering in her sleep, calling out for Tia in the most heart shattering sound the older sister had ever heard.

“Luna, wake up, you’re having a bad dream” she said softly. With gentle hooves Celestia lifted Luna out of her bed and shook her. It took more than a few shakes but soon, Luna’s eyes opened, filled with sorrow and fear. Celestia’s heart broke to see that look in her sister’s eyes, and she hugged the young pony tightly.

Upon waking, Luna felt terrified and completely alone. When it registered that she was being held by her Tia, she broke down again, pulling her sister into a tight hug.

Neither of them said anything for a while, just stayed in a pile as Celestia rocked and gently stroked Luna’s mane as she cried. When Luna managed to pull herself together she squeaked out, “Can I please sleep with you tonight Tia?”.

Celestia nodded. “Would you like to talk about it?” She asked softly.

Luna shook her head, burying her muzzle into Celestias neck. Her heartbeat was finally slowing and she couldn’t bear to see her sister leave her alone, even though it had only been a nightmare. The idea of talking about her dream also sent shivers down her spine. She didn’t want to relive that fear

Celestia yawned and gathered Luna up in her magic. She held her sister close as they walked to her room to finish sleeping for the night, and when they were safely inside, they curled up together and quickly fell asleep.

Luna woke up with the sun shining brightly in her eyes. She let out a soft moan and rolled over, and accidentally off the bed. The thud and Luna’s startled yell caught Celestia’s attention, who had been preoccupied answering letters at her desk.

“Are you alright?” She asked coming over with concern in her voice. Her mane was messy and she was still in her dressing gown, signaling that she hadn’t gotten up that much earlier.

Luna smacked her head on the ground when she fell, giving her a hard bump on her noggin but she was otherwise unharmed. She was very relieved when she woke to feel that she was still dry though. She nodded to her sister while rubbing her head and looking around. With all the adventure of the previous day, she really hadn’t had a chance to look around.

The walls were a bright white with a golden ivy mural painted on its edges. Paintings of their family, of the holders of the elements, and their friends hung on the walls. The room itself was warm and smelled slightly of warm vanilla and cloves, and all the furnishings were a polished birch. Everything seemed so light and inviting and Luna was almost jealous.

Regardless of her assurance that she wasn’t hurt, Celestia still began to look over her sister to make sure that she was ok. Finding no major injuries, and because she was being pushed off by Luna with an annoyed, “I’m okay!” She backed off.

“Fine, fine.” Celestia said with a roll of her eyes. She walked back to her desk and continued writing. “Today you’ll be spending the day with Silver Streak.” She said with a tone that conveyed that she wasn’t going to take any objections.

Luna wanted to argue but she heard her sister’s tone and decided against it. Her dream from the previous night still lingered, and she didn’t like the idea of spending the day away from her.

“Why can’t I spend it with you like we did yesterday?” She asked with wide eyes, hoping to play on her sister’s heart strings, rather than attempting to argue.

Celestia turned and when she saw Luna with puppy dog eyes her own softened. “Though it’s been fun sharing you with the rest of Equestria, I have a large number of meetings to go to today. Since you’d not be allowed to participate, I figured you’d much rather enjoy the day doing things which are not sitting in a room drawing alone.” She explained softly. “But, if you really wanted to spend all day bored and alone in our meeting room then I can arrange it.” Celestia added with a sly dip in her tone

The idea of being alone all day made Luna shutter. Today was not the day to seclude herself. “No no, I think I’ll be ok with Mr. Streak. What are we doing?” She asked curiously. He was so friendly before, she hoped he’d be just as friendly, especially if Celestia was going to make him her proxy. She also faintly hoped that maybe he’d let her bend the rules a bit.

“I have no idea, although I trust him completely, so I’m sure he’ll find some appropriate activities for the two of you” She said with a small grin, still focused on her letters.

They sat in relative silence for a while, and Luna had begun to occupy herself by playing with the bed covers boredly. She felt a twinge if pain in her bladder and knew she would be needing to relieve herself soon. After a few minutes there was a knock at the door.

“Come in” Celestia chimed.

The door to her room opened without hesitation and Silver Streak trotted In, surprisingly cheery. Luna was surprised to see him without his traditional uniform. Instead he wore light purple scarf and nothing more, a vastly different arrangement than the day before.

“Good morning little one.” Silver said with a smile. He made brief eye contact with Celestia who nodded. “Let’s get you ready for the day.” He said helping Luna up and guiding her to the door. His voice seemed less formal today, and almost fatherly in its care and tone.

With mixed feelings, Luna followed Silver Streak out of Celestia’s room and into the hall on the way to her bedroom.

A Late Breakfast

View Online

Silver Streak was an older stallion. His bones creaked and groaned so he moved slowly, and with purpose. His mane, once a dark black color was now a mottled grey, filled with light grey and white streaks. He had wings which Luna hadn’t noticed before and their feathers were similarly speckled with lighter shades. His coat was navy blue, but it seemed a bit more washed out then it did under his uniform, and it only seemed lighter next to his vibrant scarf.

Luna took all this in as she followed him quietly down the hall. Silver glanced at her every once in a while and she’d avert her eyes as to not meet them. Still, every once in a while their eyes would meet and she’d see the soft stillness in them.

“First on our agenda is to get you ready for the day.” He said matter of factly as they entered a powder room at the end of the hall.

Luna didn’t speak, she didn’t have much of a choice and though she grumbled under her breath she was thankful that he wasn’t taunting her. Instead she just took the time to look over the room.

All around her the room was pastel pink. Lace lined every soft surf, and the moulding was an elegant and detailed gold color. There was a sink and a bath, and a chest of drawers with a mattress, but no toilet. Luna sighed. She’d expected as much and yet she still found herself disappointed.

Silver smiled at her and Luna only noticed once she lowered her eyes. She immediately felt shy, and slightly embarrassed.

“Well let’s get you all prepared, your sister might have the magic to do this in a heartbeat but I don’t so it might take us a moment.” He explained as he started to rifle through the drawers of the chest.

Luna peered over his shoulder curiously, but kept her distance as best as she could. She was beginning to feel nervous but she held it back, silver seemed nice and she didn’t want to make him feel unappreciated.

The Pegasus pony pulled out two small piles and set them on the dresser. Luna tried to peek over but could only identify the colors in each of the piles, one primarily navy, one primarily Periwinkle. She then looked at him, slightly confused.

“You get to choose what you’re wearing today” Silver said with a smile. This surprised Luna and she found herself with wide eyes listening closely. Was this a trick? She gave a nod to let him know she understood.

The older stallion continued, still keeping a calm but positive attitude. “I have two outfits for you, one school uniform and one sundress. In either scenario you’ll look as cute as a button but whichever you choose will dictate our activities and the expectations I have for you”

Luna paused. Change your expectations? She thought while trying to make up her mind. If she chose the uniform she’d look less childish but it would make it more obvious that she was diapered. If she chose the dress her diapers would be more inconspicuous, but she’d look like a big filly anyway. She wanted to growl with frustration but had to admit even a little bit that she appreciated Silver letting her choose.

“I’d like to wear the uniform.” She finally said, her voice low, not happy, but not as frustrated as she’d have been without a choice.

“Wonderful darling.” He said with a warm, grandfatherly smile. “As we get ready, I’m going to be giving you today’s rules so please listen closely” Silver explained, putting away the sundress pile and spreading out the uniform.

Luna stayed still and nodded. She didn’t feel particularly like talking, both because she still felt embarrassed about the whole scenario and because she didn’t know what she’d say if she wasn’t.

“The first rule I’m sure Celestia already told you. You’re in my care so you will be obeying me as if I had the same power granted to her.” Silver walked over to her and started to pull at he onesie.

Luna froze in humiliation. She knew it but it hadn’t registered with her that she’d have to actually be dressed and undressed by the stallion. She cooperated but turned her head away with rosy cheeks. This didn’t seem to phase the older pony and he continued undressing her, leaving her chilled with only her clean diaper on.

“The next rule is that you are expected to behave yourself like a proper young lady. No flailing, no running, as if you were back in etiquette school.” He said with a nod. Before redressing her he paused and asked, “do you need to potty Little one? Now’s your chance while I have the best time to clean you up.” He prompted with a knowing glance.

Luna looked down and felt the slight nagging of her bowels and bladder. She hadn’t gone this morning and she knew if she didn’t go now it wouldn’t be long before she had to. Weighing the options in her mind she considered telling him no. She hated having to use her diapers with an audience, though she did concede it was worse to have to stay icky. Luna sheepishly nodded to her escort and to her relief he smiled and went to leave. “When you’re done knock and I’ll come back in” he said exiting with a flick of his ears.

Luna sat in the powder room alone for the first time since she returned. The idea of escape briefly flashed through her mind but it didn’t last long. It was irrational and she knew deep down that it’d be pointless. Instead she focused on performing her duties, straining against her potty training.

When Silver finally heard a knock at the door he smiled, and entered the room. Luna stood with her legs as far apart as they’d go while still supporting her standing. He barely stifled a laugh; she looked like a toddler after they’d been naughty. He saw her grimace and unhappy face, and his humor left him.

“Lay down little one and I’ll get you all cleaned up.” He said trying to sound as understanding as he felt.

Luna obeyed reluctantly, feeling her mess squishing onto her flanks. Once again the feeling wasn’t entirely unpleasant, but it reminded her of her predicament and so she was determined to hate it.

Silver came over quickly, and with a surprisingly skilled hoof, had Luna cleaned up in a heartbeat. Luna kept her eyes averted, shame over her rosy cheeks. When he’d finished, Silver began to rediaper her in a diaper with a pastel blue cover marked by her cutie mark on the rump.

“The third rule for you today is that you may only call me Papa, grandpa, or sir” he said with a grin, helping her off the ground. When Luna looked at him surprised, he added “that rule was mine”

As he helped her into the skirt and dress shirt she got a better look at them.

“All your other rules still apply, but feel free to tell me anything you may need. Rather than a foal, you’re going to be my little filly” he said smiling.

She listened halfheartedly as she examined the clothing as it was put on her. She was dressed in a light blue dress shirt with a few ruffles, and a short plaid navy blue skirt which showed off her diaper quite obviously. Each garment she tested wouldn’t budge, having had the same enchantment on it as before. She pouted, but internally she was glad to be out of the stiflingly warm onesies.

With a new diaper and her outfit snugly on, Silver led Luna out of the powder room and into the hallway where she felt immediately more self conscious. It was very quiet and her clothing brushed and rustled feeling like the loudest thing in the room. There weren’t many other ponies but the few that there were stared at her, and she looked to her hooves.

Silver, to his credit seemed to act like nothing was amiss. He took her wing gently in his and held her to him like many Pegasai do to their small fillies to keep them from wandering. Their hoofsteps echoed through the marble hall and Luna shrank into Silver, trying to make herself less conspicuous and earning a barely audible, ‘awe’ from Silver.

The pair did pass the occasional guard, most of which did their best to ignore her, especially with Silver holding a generally high rank. The maids and other maintenance workers however didn’t stay quiet. Most of them stared or giggled, and a few of them made mocking comments to her, though after a glare from Silver they were quickly silenced.

By the time they’d come to their intended destination, Luna felt tiny and horribly humiliated. In the room, which was completely devoid of other ponies, sat a table which had already been prepared with breakfast.

Luna lifted her head when they entered the room which she’d firmly fixed downward during their walk. Seeing they were alone she let out a sigh of relief and the tears she’d been holding back began to drip down her cheeks. At first, Silver didn’t seem to notice as he brought her to the table. When she made eye contact with him though, his heart broke and he sat next to her, drying her eyes the best he could.

“Oh sweet little one, what’s wrong?” He asked softly, his eyes showing his concern for her wellbeing.

Luna opened her mouth to speak but the words weren’t coming to her, so she just hugged him. Surprised, Silver paused before hugging her back and humming softly. It took her a few minutes to calm down again but when she had, the words came easier.

“I’m sorry Sil-....Papa..” she said softly. “I’m so sorry...” she said, voice slightly whiny.

“Oh sunshine...” he said giving her another soft hug, “what are you sorry for? You’ve been so good all morning”

Luna looked at him, face wet. “I-I’m sorry that I did all those things, that I hurt my subjects...” she said voice choked and small, as she buried her head in his neck

Silver’s shoulders softened and he pet her mane. “Lulu, you’re not in trouble sweetheart, this isn’t a punishment” he told her reassuringly. “Your sister wants you to be able to relax, to be able to feel loved again. Not to continue punishing you for what happened a thousand years ago.”

“Then why did she choose this? Why do those other ponies tease me and make fun if it’s about love?!” Luna shouted, her voice filled with pain and defeat. The fear and frustration from her nightmares boiling over with all that had happened in the last few days.

Silver stopped for a moment, then pulled back to look into Luna’s teary eyes. “I’m sorry that your sister didn’t properly brief them. I’ll make sure to have a word with the staff. As to why she chose this, I can’t say for sure, but I suspect it has to do with your vulnerability after your return, and her desire to fix and redo what she’d missed the first time around” he said softly. He took her cheeks in his hooves and kissed the top of her head. “She loves you, just know that. Now, let’s eat.” He said with a nod towards the table.

Luna met his eyes and slowly calmed down again. What he’d said made some sense, and as much as she wasn’t sure she believed him, she was relieved to hear that he’d be there to help her. Luna followed Silver’s gaze and moved to the table where a plate of sandwiches sat. Luna had gotten up later than expected, and it was more like lunchtime than breakfast.

Luna’s chair was much shorter than normal but also had a couple phonebooks so when she sat down she was level with the table and her plate, which had a small PBJ sandwich cut up into quarters, and a sippycup full of milk. Silver sat next to her and had his own sandwich, tuna, and some juice.

“Do you need any help love bug?” He asked softly, and Luna shook her head. She appreciated the nicknames, feeling both appreciated and also less self conscious even though it wasn’t exactly what she preferred. She ate quietly, but drinking was strange without her magic to help, and she struggled to keep a grip of the hard plastic.

Without prompting, Silver lent a wing to help steady the sippy cup, as he continued to eat his own food.

Lunch went quickly and after they were done Silver led Luna back out into the hallway. Luna felt worried again but it seemed like the halls were even more empty than before, only one or two patrolling officers passed and they didn’t pay any mind to the two of them.

Luna looked at Silver again after the second guarded passed silently, and asked in a quiet voice, “What are we doing today Papa?”

Silver paused, “If you’re patient you’ll see” he said with a grin.

Celestia finished the last of her letters and sighed. Today was looking like a full day and she wasn’t pleased. She was thankful that Luna was willing to cooperate and didn’t force her to bring her along. She did feel worried though; with the nightmare and the insecurities she hoped that Luna would be alright.

Gathering her folders and paperwork, Celestia headed out of her room and through the halls on the way to her first scheduled meeting. Though her hoofsteps echoed on the tile she could still hear the gossiping voices of her maids resting around the corner. She intended just to pass by, when she heard the word ‘Luna’ pass from the lips of one of the mares, she slowed, listening in, her heart again filled with concern. Had luna made a fuss? Caused a problem? Had she forced Silver to make a scene?

“I can’t believe she was let off just like that” the first pony said incredulously.

Another voice joined in, “Yeah, it’s a shame the only ponies who can escort her are the guards. I’d give that flank a nice hard paddling for all the horrors she amassed.”

The first pony continued, voice filled with a gross malice and twisted glee at her own cruelty. “A paddling would be nothing, I’d make her sit in her filth and get a nice big rash like the filly she is and then paddle the living daylights out of-“

Celestia had had enough. Before the other mare could finish her cruel sentiment, she came around the corner with fury alight in her eyes. “You two come with me.” She ordered as she walked to a nearby meeting room. She had time to spare before she needed to make her meeting, and this needed to be dealt with.

The two mares’s breaths caught in their throat and they followed obediently, expecting to be chastised for slacking off.

When the doors closed and all three were in the meeting room, Celestia looked at them coldly. They shrunk down, ready for a verbal beating.

“I was very clear about what I said before Luna was to return, that this does not involve you. Since you two seem to think that you’re above my request, I’m going to make it an order and clarify a few things for you.” She began, her voice as smooth as silk but as dark as night. “Luna is not being punished. I would never spank her unless she were being directly insubordinate, and I would never knowingly allow her to get a rash. She is behaving exactly as has been requested of her, not as a punishment but as a reform. She’s had plenty of trauma and needs love and support. Since you were so tactless as to allow me to hear you, I don’t doubt Luna did as well. I want you to share this next message with every other member of the staff. If I so much as think that you’ve continued this inconsiderate, hurtful, and inaccurate gossip, I’ll have you both fired” she said her voice more passionate than it had been in years.

The two maids shook in front of her, fear holding them in place. Losing their jobs was not an option.

“Do I make myself unspeakably clear?”

Both ponies nodded vigorously.

“Then go and do as your told.”

Both mares bolted as fast as their hooves could carry them out of the room. They said nothing, but Celestia knew her point had been made. Now she only hoped with a heavy heart that Luna wasn’t too upset.

Silver’s History Lesson

The lack of staff and infrequent guard activity set Luna’s mind at ease, though why all of a sudden the halls and corridors were so empty eluded her. Without many other ponies to stare or gawk, she felt comfortable holding onto Silver’s wing with more enthusiasm, allowing him to lead her to their destination. His coat felt warm beside her, and eventually she found herself leaning into his embrace as they walked.

Their hoofsteps seemed to bounce off the walls of the castle in every direction giving it an almost hollow feel. A breeze wafted through her mane, and for a moment, Luna wondered if they were going outside. Despite only traveling for a few minutes, Luna had already relaxed, the stress free environment helping to resolve the rest of the day’s anxieties. Her skirt and diaper still rustled as loud as ever and she still looked like an over sized filly, but those things seemed to fade away to the back of her mind. Unimportant and insignificant.

Luna, who was no longer paying attention to her surroundings, was surprised when they stopped, and the sudden jerk caused her to stumble. Silver was quick though, and before she could fall, he held her steady bracing as she regained her balance.

After an embarrassed shake, she smiled at Silver with a blush, and looked around to see where exactly they’d decided to stop.

“I thought this could be some fun, help catch you up after so long on the moon” Silver explained as he opened the door to a large room.

Luna’s mind filled with memories as she recognized her childhood classroom and library, a place she thought her sister would’ve gotten rid of so long ago. Brief flashes of happy memories of their studies and old books passed through her mind as she walked inside with Silver. The room seemed to have been left untouched almost as long as she had been gone. Books were pristine on the shelves, albeit dusty, and her old school work still sat organized on a desk in the corner. When she went to look more closely, she noticed that the work on the table was much older than the things she had been doing before she left. They were projects, and artwork from when she was very small.

For a moment she wondered why those would be out of storage, but her thoughts were pulled away and lost as Silver called her name.

In front of him, was a neatly organized desk with paper, colored pencils, and crayons, and behind him was a chalkboard with the words “Mr. Streak” written on it. Had Luna not been immediately interested, she might have giggled at the way Silver was appearing to look posh and elegant.

“Please take a seat miss. It’s time for your lesson” he said with an excess of formality.

She nodded, and obliged, taking a seat at the small desk. Her diaper added an inch to her height when sitting and she felt weird in the hard chair with it underneath her. Lifting her head, and sitting as comfortably as she thought she would ever be, she focused her attention on Silver.

“I think today we’ll focus on the The History of your departure...”

“Thank you so much Princess, our village is at your service “

Celestia watched a periwinkle blue unicorn bow deeply with a large smile on his face right before being escorted out of the throne room. Without needing to ask, a guard at the door nodded.

“That is all for today.”

With a brief break now in her schedule, she sighed loudly and slouched in her chair, closing her eyes. The day wasn’t even half over, and already Celestia felt drained of all energy. Perhaps it had been her long night, or maybe she was just tired from caring for Luna for the last few days.

Regardless of the reason, it felt genuinely wonderful to relax for a moment and sit in peace.

Unfortunately, the quiet serenity she enjoyed did not last long, though she hadn’t expected it to. Minutes after she took her pause, a clattering and commotion came from behind the doors, which drew her gaze, and she sat up straight once again.

Moments later, a group of guards struggled into the courtroom, pulling another pony between them. The newcomer bucked and kicked and struggled, letting out guttural shrieks with nearly each thrust of their body.

Eventually the guards managed to steady their ward between them, keeping them firmly still with the aid of chains. “Greetings Princess Celestia.” The lead officer in the group did not hold any of the restraints, and thus addressed her promptly.

“Greetings” she replied, interest piqued. It was very infrequent that someone come to the court so violently. Especially when even those with the most egregious crimes managed to be cordial, if crass, in the courtroom. “Who has the royal guard brought to my attention?” She asked glancing at the pony tied and surrounded.

“The pony before you is called Cobalt Cross. A former blacksmith, Mr. Cross was found to be part of the ancient rebellion. We arrested him today after we found him spreading false information in the capital about Princess Luna, and attempting to start a new rebellion.” The guard seemed to smirk, though he attempted to keep it to himself. Cobalt struggled again but was given a firm smack to the back of his head and he stopped. “We suspect that there are more members of the rebellion, but no others have shown themselves, and Mr. Cross refuses to enlighten us.”

Celestia took a moment to process this information, as she sat in front of her guards and council. This cannot repeat again. We cannot start another war.

“Why have you decided to start the rebellion once again?” She asked, addressing Cobalt Cross directly. His eyes widened, as if surprised to be spoken to.

“Our mother Luna has risen again. She will become the one true ruler and we will return to the sanctity of darkness like we are destined to do.” His voice was calm, but there seemed to be a strange manic feeling to his voice that made Celestia uneasy.

Again she addressed Cobalt, clearer and more forceful, “Why now? What makes you think that Luna has returned?”

The stallion smiled widely, “The story books have told of her return for thousands of years. Nopony took us seriously but we will always remain loyal to her as long as she lives, teaching our children, and our children’s children about the beauty of the night. We will be victorious, and Luna will be returned to her former glory.” He said with twinkling eyes. His face flashed with darkness then, and he once again began to struggle, “What have you done with her? Where is she?! She should be here in this court, and yet her throne is empty!”

Celestia paused and debated lying to him. If she told him that she had her killed, then Luna would never be allowed freedom, and she would never force that upon her. If she denied Luna’s coming, it would only delay the inevitable. She debated it in her mind for a moment before coming up with a relatively simple solution.

“Luna is not available for council. She has had a long way to come and required rest and rehabilitation after her arrival. She will return to council when she is fit.”

Cobalt squinted at her, as if he was trying to decide whether he believed her. Before he could argue, she continued, “as for you, the royal guard will be taking their council with you for the time being. I’d like you to discuss with them the status of the rebellion and if you do not, then you can be sure that we will do everything within our power to prevent the new coming of Luna.” She said carefully. “Take him to the dungeons”

Cobalt cross screeched and fought his captors, yelling “you can’t do this! We will rise again!!!!” Before he was dragged out of the courtroom.

As they exited, one of her other councilmen approached the throne, “Sorry for the interruption my grace, but you have another council meeting”

Celestia made a soft sound of frustration and followed him, anxiety now pricking her mind at the idea of a new rebellion.

“...who was promptly arrested then executed.”

Though she had been enthusiastic at first, Luna sat at her desk doodling on her paper out of extreme boredom. The first bits of the rebellion were the most interesting. After being sent to the moon, her loyal patriots attempted to return her, and overthrow the crown. When they were ultimately defeated, the expected happened.

Luna half listened and continued to doodle as she was told of the leaders who she’d never known personally were reprimanded and the state was put back into order. Just as she’d expected, Celestia wasn’t exactly hard to read, at least, she hadn’t been back then.

Now, she reflected, her sister was nearly impossible to read. She’d changed so much as a leader from when they were young that she almost seemed like a different person entirely.

“Ahem.”

Silver’s irritated voice drew her attention again for the fourth time that day and she blushed, embarrassed at her lack of attention.

“If you’re not ready for this lesson, then perhaps we should find you something more appropriate to do.” Silver said with an annoyed frown.

Though she certainly wanted to do something else, Luna wasn’t sure if the alternative would be better or worse. “What else would we do?” She asked problingly. As she returned her attention to the moment at hand she began to notice the fullness of her bladder, and she sighed at the inevitability of her situation.

Silver streak smiled at the return of Luna’s attentive gaze. “Well I suppose we have two options. Your sister is likely still occupied with court and a council meeting, so we could take a stroll in the garden, or spend some time reading.” He said looking at the piles of books on the shelves around them.

The shelves, dusty as they were, were one of her favorite places before her banishment, and looking upon the rows and rows she had before her, the choice was immediately obvious.

“Let’s read today” she said standing. Silver gave her an approving nod, and moved to sit at another table with his own book. As the pressure from her body lifted from her flanks, she could feel her bladder more urgently now.

Luna hesitated a moment before her cheeks grew red, and she let go of her bladder, letting the warm feeling spread along the inside. Without a word she turned down an aisle of the library and went on a hunt. The feeling of the warm diaper was nice, much more pleasant than when she’d been messy. Though she tried in her mind, it was starting to be quite difficult to hate the wetness around her flanks, especially with the warmth it provided and the pleasent way it rocked against her sensitive parts.

After only a few minutes of searching, Luna managed to find one of her favorite fantasy novels, and she snagged it quickly, before laying down and beginning to read. Soon, her eyes began to droop, as her energy wafted away.

“Luna, wake up!”

Luna’s head felt heavy and she rubbed her eyes, clearing the sleep away from her head as she tried to remember where she was.

“Luna look at the mess you’ve made! And what have you done to that poor book?!”

When she could finally make sense of where she was, Celestia was standing over her looking at a book below her head which was now bent and crinkled. Luna began to sit up and felt wet.

“What happened? You were told to inform Silver if you needed a change, why would you let this get so bad?” Celestia ‘s vice was filled with worry and frustration, and it pained Luna to hear that she had caused it once again.

Luna was about to explain herself, explain that it wasn’t so bad when she realized why she’d felt so wet. Under her, from hind quarters to chest, was a large puddle of pee, faint smelling but drenching her. Her shirt and skirt were both sopping, and the book seemed almost saturated in the first few pages. Her cheeks went bright red, and the words were stuck in her throat. She wanted to be mad, wanted to lash out but she couldn’t get the words out .

Without saying anything else, or waiting much for her sister’s response, Celestia lifted Luna with her magic and began to leave the library. The two of them passed Silver on the way out and he looked sheepishly at Celestia who ignored him.

Outside the room, in the hallway, Celestia summoned a bench, and sat down. She removed Luna’s wet clothing with magic, and her extremely soggy diaper. Before Luna could think to move on her own accord, Celestia pulled her sister over her lap, and administered three hard smacks in quick succession, which echoed down the corridors. The sting seemed to wake Luna from her senses and her eyes welled up in tears from shame and indignation.

“If you ever break my rules again there will be more than three spankings” Celestia said curtly before standing to walk Luna further down the corridor. Her voice, despite sounding strict was full of emotion, something else had bothered her, but Luna was too upset to put much mind to it. Her body was cold and obviously wet from her nap time accident, and she followed Celestia silently until they made their way back to the pink and gold bathroom from earlier that morning.

When the two girls entered the room, Celestia quietly lifted Luna onto the changing table, and began to prepare a bath. As she sat on the cool tacky seat, Luna felt her flanks burn with angry fire and she let out a stifled whimper. What had seemed at first to have been the sting of her spanking, had also been the beginning of a rash all over her bottom, the pain radiating through her body.

At the sound, Celestia could feel her heart break for her little sister. She left the warm water which was now filling the tub, and she moved towards Luna. Both sister’s eyes were full of tears, and Celestia hugged Luna so tightly she thought she might have broken her. They stayed there for a while, both getting equal parts wet from Luna’s damp fur as the tub warmed up. When they finally separated, Celestia had to shut the tap off quickly to not overflow the tub.

“Would you like bubbles Lulu?” She asked quietly, holding out a soap bottle. She thought about it for a moment, and nodded. The fragrances would help her relax and the bubbles would make her feel less exposed. Celestia obliged and poured a generous amount into the tub and mixed it in, creating a decent pile of bubbles before lifting Luna and setting her in the warm water.

Luna desperately wanted to hate her sister for what was happening, she wanted to lash out, scream, be angry. She wanted to accuse her sister for hating her and doing this to humiliate her, but with every brush, every comb, and every gentle rub, she only felt love radiating from Celestia, and her anger melted away like the dirt in the bath.

Both sisters stayed quiet as the bath continued. Celestia used a small brush and helped clean the pee smell out Luna’s coat. They lathered her mane gently, then combed it out slowly with conditioner, and when the cleaning was done, Celestia left Luna to play with a few water toys and paint while she gathered an outfit and clean diaper.

The quiet was calming, and though the toys were available, Luna decided just to lay back and relax in the soapy water.

When Celestia had returned, Luna felt more calm thn she had in years. Soft, and clean and loved, she exited the bath into an awaiting towel, wincing as it brushed her tender flanks.

“I’ll make sure to get you some lotion for your rash.” Celestia said as she finished drying Luna with the towel.

Her magic was much quicker that Silver’s work by hoof, and after using a liberal amount of lotion, Celestia diapered her up snugly. To Luna’s mild disappointment, her diaper was easily twice as thick as before, and was followed shortly by the babydoll sundress she had refused before.

It made sense that it’d be thicker, but she disliked it nonetheless.

“Are you still tired honey?”

Celestia’s voice broke through her train of thought, and after assessing her own tired limbs and drooping eyes, she nodded.

The two sisters walked to Celestia’s chambers. The halls were still deserted like they had been before, but they seemed even more empty for some reason, which bothered Luna up until the moment she set her head on Celestia’s pillow, and she fell quickly asleep.
