> Dear Diary > by Wandering Pigeon > -------------------------------------------------------------------------- > The Princess and the Pee > -------------------------------------------------------------------------- At some point, it struck Twilight that she was reading Princess Celestia’s diary. Her diary. A journal one dumped all of their darkest secrets, unfiltered thoughts, and deepest wants. It was an inherently personal venture to write one, and likewise, it was an inherently violating venture to read one. Especially without permission. And at this point, right now, Twilight realized that she was violating the privacy of Princess ‘Throw You To The Moon If I’m Mad Enough’ Celestia. Dear Diary, I wet the bed today. Just reading those two lines made Twilight’s blood run cold. Her head jerked up and she took in the room around her. Rarity was concentrating on sewing. Sweat ran down her brow as she fussed over the finer points of some curtain’s needlework. Fluttershy was feeding Angel carrot slices, cuddling the tiny rabbit against her chest as she did so. Angel had an unamused glare on his face, even as he nibbled away. To be fair, mere moments ago Fluttershy had thought he’d been crushed by a pillar. He really couldn’t blame her for coddling him a little bit. Rainbow Dash and Applejack were rattling off increasingly stupid dares, hoping to come up with the ultimate tie breaker for their competition. Pinkie sat between them, shaking her head at anything that didn’t satisfy her imagination. Those three would be at it for a while at that rate. Lastly, Spike was swatting a book at Star Spiders with increasingly high pitched shrieks. The spiders, for their part, had seemed to realize Spike didn’t actually have the guts to splatter them all over the floor, and so had stopped flinching with each fake out swing, thus perpetuating a cycle. None of her friends knew what she had just read. They couldn’t, of course, but that irrational fear had briefly overtaken Twilight anyway. She couldn’t shake the feeling that she had just done something wrong. That she had just learned something she shouldn’t have. She really, really shouldn’t be reading another pony’s diary like this. Was it too late now? Now that Twilight had read that sentence, she couldn’t unread it. Now the knowledge would forever be with her that Princess Celestia had wet the bed in her… Twilight was assuming twenties. The diary seemed to be just after both of the Royal Sisters had ascended and took the throne as co-rulers. That was way past the acceptable age of being a bedwetter. In fact, it was downright humiliating at that point. And Twilight knew this downright humiliating fact about her mentor now. Forever. Should… should she even allow herself to keep reading now? Maybe… maybe context will make it better, Twilight decided. Context was key, of course! There was no way there wasn’t more to this story. Surely she would feel less guilty if she understood why Celestia had wet the bed, and not merely that she’d done so. It would also improve the way Twilight saw Celestia. As it stood, she wouldn’t be able to look at the Princess the same way ever again. She had to know more, for her sake. Yes, she was doing this for Princess Celestia and certainly not her own morbid curiosity… right? Twilight dove back into the book, refusing to dignify that question with an answer. Dear Diary, I wet the bed today. I just… woke up, and my sheets were damp. It’s quite embarrassing to admit, actually. I don’t believe I’ve ever wet the bed as a filly and now here I am, a grown mare waking up in a puddle of her own urine. Briefly I thought my dreams might have been the cause, but I couldn’t even remember them, let alone if they had been scary enough to cause... this. I brought this up to Luna (stealthily, mind you. It wouldn’t do for her to learn what her big sister had done, after all) and she said she couldn’t remember a time where either of us had as well. Perhaps it was just a freak occurrence. Twilight brought her head up from the diary, as though coming up for air. That was… incredibly unsatisfying. Just a freak occurrence? That was the only justification for Princess Celestia wetting the bed? She hadn’t been doing paperwork late into the night and passed out before she’d had a chance to use the restroom or something? It was just… an accident? Twilight fought back a frown, tightening her lips instead. Perhaps she’d just overreacted to the whole revelation. In the end, accidents did happen. Surely this had to be one of those. She prepared to close the diary, ready to leave it behind. It had been a mistake to ever start reading it in the first place. Now that she’d had her one scare, it was time to stop. Except… her eyes glazed over the next entry on the page. Dear Diary, It happened again. Twilight froze, knowing full well she wouldn’t be able to just leave it alone after seeing that. She didn’t even start up a new internal debate in her head. Scanning the room, she confirmed her friends were all still wrapped up in their own business, none even looked in her direction. She flipped back to that page. Dear Diary, It happened again. I couldn’t even make it two nights before I had another… accident. And again, I don’t even remember doing it! I just woke up in the middle of a dream to find my bed was soaked. I came up with an excuse for the maid, but this is the second time in three days she’s had to wash my sheets. I fear she’s beginning to suspect something. It’s got me so worried that I can’t even concentrate on work. Luna asked me what was wrong earlier. I lied, of course. How could I tell her the truth? I’m really hoping this is the last I’ll have to mention all this. I’m going to forgo my nightly tea this evening. Surely that will help. As Twilight read the last, hopeful line of the entry, she was stumped. How could there be no reason for the Princess of Equestria to suddenly wet the bed? And twice, for that matter? “...Just a few more…” Twilight mumbled to herself. Surely there were clues she could decipher from reading the diary further. Maybe she could catch a pattern Celestia herself had missed. Yes… that was a good enough to keep going. She flipped the page. Dear Diary, Two nights in a row! This is simply scandalous, I can’t believe my bedwetting has become so bad. What am I going to do? I can’t let the maid see my sheets again or she’ll find out. And as soon as she does, the whole castle will to, I’m sure of it! I’ve stashed my sheets in my closet for now. I’ll just sleep on the mattress tonight while I think of something to do. But if it happens again… Twilight swallowed, her throat dry. This was insane! Princess Celestia almost seemed… afraid. The hastily scrawled words on the page before her only added to that notion. Twilight could already picture a much younger Celestia, curled up in the corner of her room so nopony could look over her shoulder as she shameful detailed her bedwetting to her diary. A small, small part of her knew it was wrong to keep going at this point, but another, much larger part of her knew she had to keep going. If she didn’t see how this all played out, it would eat away at her. She was sure of that much. After all, was Princess Celestia still wetting her bed to this day? If Twilight didn’t keep reading, she would never know. Her eyes drifted to the next page. Dear Diary, NO NO NO NO NO! This can’t be happening, not to me! I can raise the sun, but I can’t stop myself from peeing when I go to sleep? It’s ridiculous! Now my mattress is all wet, and I don’t know what to do. I think I need help. But I can’t talk to anypony about this. Nopony can know that the Princess is a bedwetter... Twilight squinted, trying to read that last line again. The words were all smeared, as though they’d been disturbed back when the ink had first been laid. The parchment around them was all stiff and wavy in some spots, as though at some point it had gotten wet… Then it hit Twilight. Tears. Celestia must’ve been crying as she wrote, probably with her stained and smelly mattress close by to serve as a constant reminder. It was all so… vivid to her. As if she could actually see it happening. She had to know more. Her eyes dropped down the page again, surprised to see a new entry with the same date as the one above it. Dear Diary, A lot’s happened this morning. I guess I should write everything down, maybe it will help me process it all a little better. I was pacing around my room trying to think of something I could do… Celestia was pacing around her room, trying to think of something she could do. But no matter how long or hard she racked her brain, it remained devoid of ideas. Her pace increased, as though that would help her at all. If anything, it only made her dizzy as she continued to trace a circle in the floor of her room. Coming back around, her eyes unfortunately met her bed again. The bare mattress had seen it’s comforter and all of it’s sheet vacated just the previous day, leaving nothing but a few pillows resting on its head now. And, of course, a massive yellow stain in the center. The stale stench of urine still hung in the air, making Celestia’s eyes water in more ways than one. It was still hard for her to believe this was happening. In just five short days she’d managed to wet the bed four whole times! This latest one catching her in the middle of the night, too. She’d awoken right in the middle of a dream, and found herself halfway through soaking her mattress. With wakefulness not even fully upon her, she’d simply allowed herself to finish, not realizing the ramifications of what she’d done until she’d rubbed the sleepiness from her eyes. To make matters worse, her bed wasn’t the only thing that was wet. Pee had clung to her coat, dampening her undercarriage and inner thighs with its smelly presence. She desperately wanted to clean herself up, but Celestia was too nervous to leave her room now to take a bath. All it would take was one random passerby to walk by her room and notice what she’d done. It didn’t even matter that it was still nighttime, guards had begun rotating shifts to work at all hours at Luna’s request. No time of the day was safe for her to leave this mess alone. Celestia whipped her head away from her bed, unable to look at it. Her flowing mane buffeted her face, it’s presence wiping away a few of the tears that had made a beeline down her cheek. As she turned again, continuing to pace frantically, Celestia now came face to face with her vanity on the opposite wall. It’s mirror let her catch sight of herself. Disheveled mane, red, puffy eyes with dark circles forming beneath them, a barely contained frown… She was a mess, through and through. How could she not be after all that’s been happening? Unable to bear the sight of herself any longer, she sped up once again. Halfway through her circle, Celestia caught sight of her closet. The tightly shut door was yet another reminder of her shame. No matter how much she didn’t want to think about it, she knew her bedsheets were back there, wedged into the very back to try and hide the shame of the no-doubt permanent stain that had formed on them. What in Equestria was she going to do? Her pacing picked up again, but this time Celestia pointed her head to the floor. She couldn’t bare to look anywhere in her room as she cycled around again. She knew she didn’t have unlimited time. At some point today, she’d have to venture outside of her room, or else somepony would come looking for her. In fact, what time was it right now? Wouldn’t she need to-- Knock knock knock. Celestia froze, hearing the blood-chilling sounds of somepony at her door. No… No no no! She clenched her jaw, body shaking. She was too late; her useless pacing hadn’t done anything to solve her problem! Maybe she could still do something. What if she set a fire? That could cover up her little… accident, right? Surely whoever was at the door would get scared and run off if that happened. Or maybe-- “Celestia?” Came a familiar voice, even when muffled by the door. “Are you in there?” Luna. It was Luna who would be the first to find her like this. Celestia’s heart sank. Could today get any worse? “Y-Yes?” She stammered. So much for even keeping up the facade that things were okay. “What have you been doing?” Luna asked, an accusatory tone punctuating the turn of the door knob. Celestia’s pupils shrank. “Wait!” She dove for the door, her panic so great she forgot her magic would’ve done a better job than her body. It might’ve even spared her the humiliation, because she failed to stop her younger sister. “You were supposed to raise the sun five minutes--” Luna froze, taking in Celestia’s unkempt appearance and the sight of her damp mattress all at once. “--ago…” Celestia closed her mouth, lips twitching. She could actually feel tears welling up in her eyes. For a moment, dead silence hung in the smelly air. Neither spoke, Celestia from shame, and Luna from pure speechlessness. Celestia sniffled. It was all over now. Luna knew, and soon the whole castle would, and then the entire country might as well. So early into her tenure as a Princess and her name would be dragged through the mud, all because of something she couldn’t even control. She sniffled again. “Sister…” Luna finally spoke. “Did you…” The question remained unspoken, but the message was clear. Celestia just nodded blinking back tears. Luna took a step further into the room. Celestia moved to the side, knowing it would be pointless to deny her sister access now. She could only watch as Luna moved as close as she dared to the bed, and inspected the drying stain. “Uhm… where are your sheets?” She asked, innocently enough. “I-I…” Her voice caught in the back of her throat. Giving up, she merely pointed to her closet. Luna moved to it, propping it open with a flick of magic. The door creaked as Luna brushed it to the side, a fitting noise for the reveal to come. Keeping her horn alight, Luna levitated out the bunched up silk. Her magical aura moved from the entire ball to just the top corners, letting the sheets unfurl in front of her revealing the darkly colored spot of shame. It made Celestia lower her head to the floor, cheeks flushing. Luna let the sheet drop unceremoniously to the floor, and turned to look at her older sister. “Has this… been going on for a while?” She swallowed, and opened her mouth to speak. The words came out choked, forcing her to give up and just nod. She wished she could clarify further; now Luna may suspect this had been going on longer than a mere week. “I see.” Her eyes swiveled from the bed to the sheets, and back again. Luna’s face tightened, as though she was trying not to laugh. Celestia appreciated that much, but she doubted her little sister would be able to hold back for long. “L-Luna, I--” “Perhaps you should see the Royal Physician,” Luna suggested suddenly. Celestia flinched. “N-No!” Have another pony learn of her predicament? Absolutely not! She was already going to have her hooves full just trying to convince Luna not to tell other ponies. “Tia, please,” Luna said, the use of her childhood nickname slipping out. “I can understand if you’re embarrassed, but--” “I am,” Celestia suddenly cut her off. As ashamed as she was, she was finding it a little easier to talk now. “Luna, you have no idea, okay? This… I can’t tell ponies about this. What if it gets out that I… that I’m a…” “Bedwetter?” Luna offered, though hesitantly. Celestia swallowed. “T-That, yes. Please, I can’t have rumors spread about this. We only just became Princesses. What if citizens started to doubt me over this? It could… could…” “Okay, okay.” Luna held up her hoof. “I can sympathize with that, I suppose. But surely you don’t want this to keep happening.” Of course not, Celestia bitterly thought. But what could she say to convince Luna she’d be alright? She didn’t even know why she was wetting the bed. But there had to be a reason. What would sound plausible? “I… I’m just stressed,” she said, unconvincingly. “Stressed?” Luna tilted her head, brow raised. “Yes!” Celestia winced. That sounded just a bit too eager. “I… There’s been a lot of work piling up lately, and I must not be handling it well, that’s all. I’m sure once things slow down a bit I’ll be able to put this whole thing behind me.” “Well…” Luna scratched her chin, as though considering. “I suppose if that’s all there is to this, then there’s no reason to get a doctor involved.” “Yes!” Celestia cried in agreement. “Thank you.” “But you’re going to keep ruining your linens at this rate,” Luna pointed out. Celestia’s ears drooped. There was always a catch. And unfortunately, she hadn’t figured out her way around this one yet. Her eyes darted between her bed and her sheets. “Well…” She had nothing, not even a plausible fib that would get Luna off her back. Was there really nothing she could do to keep the issue at bay? “If I may,” Luna suddenly said, snapping Celestia from her thoughts. “I might have an idea that could keep your sheets dry tonight.” “Really?” Celestia’s demeanor brightened considerably. “What is it?” “First.” Luna pointed to her drawn curtains, opening them to reveal a dark night sky that held no moon. “You need to raise the sun. And I’m guessing you should take a bath too.” Celestia instinctively locked her hind legs, feeling her dry, but sticky coat back there. “I… suppose.” “And we have a busy day too,” Luna considered. “So I’ll visit you tonight, then. By then I should have aquired everything I need anyway.” Celestia’s ears pricked up at that curious statement. Maybe it was just her imagination, but she felt like Luna was dodging the question. Though, she couldn’t deny that her sister raised some valid points. The morning had gone without the sun long enough. “Okay,” she relented. Her eyes looked to her doorway, but then back to her bed. A prick of worry tightened her chest. If she left to go raise the sun, who would take care of… her accident? “Leave it to me,” Luna said, as if she had read her mind. Though, to be far just reading the look on her face would’ve been enough. “Are you sure?” Celestia asked. Luna nodded. “I know a spell or two that might do the trick. And if not, I can just burn them, right?” Celestia actually giggled. Of course Luna thought of the same thing she had. “Well, alright.” She started to leave, making it halfway through the doorway before catching herself. She whirled around. “Luna… you won’t tell anypony, right?” Her sister smiled. “Of course not, Tia.” Returning the smile, Celestia breathed a sigh of relief. “Thank you, Luna.” She left, with only fleeting thoughts of what awaited her tonight to accompany her. “Whatcha reading?” Pinkie smushed the side of her face into Twilight’s, knocking her out of the zone she’d been entranced in. “AH!” Twilight flinched, just barely managing to slam the book shut before Pinkie had a chance to read a single line. All of a sudden, she became aware that there were ponies--and a dragon--around her. And her outburst drew their attention up to her. “Uh…” Twilight looked back to Pinkie, who still awaited her answer. “N-Nothing.” “Really? You looked really into it for it to be a whole lotta nothing,” Pinkie pointed out. Twilight gulped, bring the diary close to her chest. She couldn’t let anypony else know what she’d been reading, that much was obvious. “It’s just more about the secret passages and stuff,” she muttered. “Okie dokie lokie.” Pinkie smiled, that answer appeasing her finally. “Hey, do you have an idea for a most-daring-pony dare?” “Uh…” Twilight looked out to her friends. Rarity had already gone back to her sewing, Fluttershy to Angel, and Spike to his escape from the Star Spiders. Rainbow and Applejack, unfortunately, kept their eyes glued to her. No doubt on the edge of their seats for a potential tiebreaker challenge. Twilight scoured her brain for ideas, but the image of Celestia in wet bed sheets kept popping up to the forefront of her mind. She couldn’t escape it. “Sorry, I don’t know,” she admitted finally. “Aww!” Pinkie flopped onto her back, defeated. “Then I guess it’s back to the drawing board.” Groans erupted from Applejack and Rainbow Dash’s corner of the room. “Sorry to bug you Twi,” Pinkie said as she hopped up back up to her hooves. She bounced off, leaving Twilight alone on her end of the room again. “No worries,” she muttered. When noponies eyes were on her once again, she threw the diary back open, flipping back to her lost page. There was a second entry logged with the same date as the last one, so she picked up reading from there. Dear Diary, I can’t believe this is what Luna had in mind! When she showed up at my room tonight, I had no idea what she planned to do to me… The day was finally over. A mountain of paperwork had been, well, not finished, but rather just turned into a slightly smaller mountain. Court had been held, and even saw a few disputes settled amidst the hours of bickering. And now, the sun had been lowered. Celestia closed the curtains to her room, satisfied now that the moon had reached its peak. That meant Luna would be here soon and she could finally learn what her sister’s plan was to stop her from wetting the bed. She had to admit, she was getting her hopes up. After the better part of the week spent waking up to damp shame, she was finally going to have her problem solved. Maybe it was a little early to be celebrating, but Celestia couldn’t help it; she grinned wildly. Luna had already made good on one promise. Celestia had returned to her room recently to find her bed had been made. Nary a stain or a damp spot could be found on them either. She’d even flipped the mattress just to be sure Luna hadn’t done a poor job of trying to hide it, only to be pleasantly surprised. I’ll have to ask her what she did, Celestia thought. It must’ve been a spell of some sort, but what magic could be so efficient for such an… undertaking? Well, it wouldn’t really matter if she learned it or not. It’s not like she would need it anyway so long as Luna’s plan worked. As if on cue, there was a knock at the door. Celestia smiled, her anticipation growing. With her magic, she opened the door, revealing Luna on the other side. Her sister still had her regalia on. It was no big surprise; she had just been working after all. Celestia had already shed hers, leaving her tiara and necklace on her nightstand atop her diary and her golden shoes were lined up neatly on the floor beside it. Luna’s attire wasn’t the only thing she’d come with, however. A thick, pale blue strap wrapped around her chest, and looped down to her side where it held a matching bag. Curious. Celestia could only assume these were Luna’s preparations she had mentioned earlier. Luna gave her a somewhat eager smile. “Greetings sister. I trust your day was… busy.” She gave a playful sigh. “Ugh, you would not believe me even if I told you.” The two shared a laugh at their own expense. They, more than anypony, knew just how demanding their jobs were. “I am looking forward to a restful, and dry sleep,” Celestia said as their chuckles died down. “I hope you can get it,” Luna said, levitating the bag off of her her body. “But if not, that’s what this is for. Can you lie down on your bed for me?” Celestia paused, her smile faltered into a more neutral face. Though hesitant, she followed Luna’s instructions, first sitting down on her mattress before lying back on her spine. Her body sank into her comforter ever so slightly. “So… you said you had a wait to keep me from… uhm, wetting the bed,” Celestia prodded, hoping she’d heard wrong. “Did I?” Celestia though she saw the corners of Luna’s mouth poke upwards before dropping back down again. She unzipped the bag. “I’m sorry, I only know of a way to keep your sheets dry. When it comes to stopping your nighttime… uh, accidents, I’m afraid I don’t have anything like that.” “I see.” Celestia’s heart sank a little. So they were treating the symptoms, not the problem itself. To be fair, that was easier when even she didn’t know what the problem was. “So what is your idea then?” “This.” With a flourish, Luna withdrew something large, poofy and white from the bag. Cutesy little crinkle sounds came from it as it moved, betraying it’s plastic nature. It didn’t take long for her to realize what it was. “A DIAPER?!” Celestia cried, pushing herself back up. “Sister please!” Luna reached over and pushed a hoof onto Celestia’s mouth to silence her. “You wouldn’t want a patrolling guard to here you, would you?” Blood burned under Celestia’s cheeks, and she realized just how loud she had been. She brushed Luna’s hoof away. “Surely you can’t be serious, sister.” “I know, I know,” Luna insisted. “It’s embarrassing, right?” “Immensely!” “Well so is wetting the bed,” she retorted. Celestia snapped her mouth shut, blush growing ever brighter. She couldn’t dispute that. “But… but…” “It’s not ideal, trust me, I know,” Luna assured her. “But at the same time, what else can you do? If you refuse to see a doctor, then we must provide something to protect your linens.” “But a diaper?” Celestia protested, inching away from it. “I’d rather ruin my sheets again. After all, you can fix them, right?” “Not really.” Luna admitted with something of a wince. “I ended up burning the old ones and just got you a replacement set.” “O-oh…” Truthfully, Celestia had been joking when she agreed to that. Luna set the diaper down on the bed, and began to unfold it. “Look, it really isn’t that bad. You’ll just have to wear them at night until your problem goes away. I made sure to get the nighttime diapers, so they’re thick enough to handle whatever you can throw at them. Not to mention,” Luna winked at her. “They’re far cheaper than just buying a new bed every day.” Celestia furrowed her brow, in no mood for jokes. “But I’m not a foal!” “That’s why I bought you adult diapers.” “Luna!” Celestia cried indignantly. Her sister fought down a smile and cleared her throat. “Kidding aside, this is the best solution I could come up with. Unless you have a better one, that is.” Celestia bit her lip. She hated herself for not being able to come up with a good enough reason she shouldn’t wear a diaper. “But I don’t want to!” What am I, a filly? Celestia frowned at the idea that she was resorting to such foalish tactics. Luna sighed. “Okay… how about this. If you can keep your diaper dry for a week, then you’ve probably gotten the whole thing under control. Does that sound good?” Celestia’s frown deepened. Diapers for a bare minimum of seven nights? Absolutely not. “One night,” she countered. “If I wake up tomorrow dry, no more diapers. Ever.” “And if it’s a fluke?” Luna asked. Celestia’s thoughts leapt back to the day after she’d first wet the bed. She’d woken up dry that morning, come to think of it… “Fine, two nights.” “Four,” Luna returned, rotating the unfolded diaper to face her. “If you stay dry for the better part of a week, that should be good enough.” Celestia cringed. She realized that Luna had all but tricked her into agreeing to wear one now. But still, four nights was better than seven, and she doubted she could convince Luna to drop it further. “...Okay.” Luna patted the bed, encouraging her to lie back down. With a sigh, Celestia did so, angling her body in preparation for the diaper. She flopped her head back, and stared at the ceiling. How has my life come to this? “Legs up please,” Luna said. Groaning, Celestia obliged. She squeezed her eyes shut as she felt the diaper slide underneath. There was a tug as Luna pulled her tail through a hole in the diaper’s behind. “Okay, you can set them down now.” Her legs dropped an inch, just enough for the top of Celestia’s plot to make contact with the diaper’s poofy interior. She froze, shivering. Luna’s head moved out from behind Celestia’s legs. “All the way down, Tia.” Celestia took a long, deep breath. This time, she brought her legs all the way down. Her muzzle scrunched as her plot sank into the poofy padding of the diaper. By the time her hooves came to rest on the bed, Celestia’s entire face was a deep shade of red. “Come now,” Luna said as she reached into the bad. She withdrew a small canister that made Celestia’s brows tick up. “It’s not so bad.” “What is that?” Celestia pointed. Luna held the canister above her sister’s pelvis. “Foal powder.” She turned it over, and sprayed Celestia’s crotch with the contents. “Foal powder?!” Celestia’s voice squeaked. Luna set the canister off to the side, it’s job done. “But of course. You wouldn’t want to get a diaper rash, would you?” “...No…” Using her telekinesis, Luna wrapped the diaper up and around, allowing it to swallow Celestia’s waist. As the padded prison closed around her, Celestia could only bury her hooves in her face in shame. She was The Princess of the Sun, reduced to wearing a foal’s garment to keep her bed dry. Surely, there was no greater humiliation. Luna pressed the diaper’s tapes down with her hooves, packing up her bag with her magic. “And there... we... go!” Celestia didn’t move. She didn’t want to hear the crinkling sounds of her diaper as she did. She didn’t want to feel its presence spread her thighs apart, or let it’s soft insides rub up against her. If she stayed perfectly still, maybe she wouldn’t have to. Luna rolled her eyes as she stood up. “Come on.” Grabbing Celestia by the hoof, she forced her sister to sit up. The crinkles from her diaper were thunderous. Celestia winced, pretty certain the entire castle had just heard. “Don’t worry about it, sister,” Luna told her. She giggled. “Actually, it makes you look kinda cute.” “Luna!” Celestia cried, her face boiling. Luna just giggled again, relishing her sister’s embarrassment. Standing, she grabbed her bag as she left the bed. “That should cover your for tonight. I’ll come check on you in the morning, okay?” “Okay…” Celestia mumbled. She shifted her legs, trying to find a comfortable way to sit in her new diaper. All she accomplished was squishing the padding up against her privates, sending a shiver down her spine. “Good night, Tia,” Luna said as she left, waving to her. “Good night,” she mumbled back. When Luna finally shut the door, everything was quiet. Celestia then dove into her pillows, burying her face in shame and disturbing the silence with a new round of crinkles. The last few nights of waking up in wet sheets almost didn’t compare to the humiliation she felt now. Rolling over, Celestia settled down in her bed. Her horn lit up, and she levitated her diary out from under her regalia, bringing it close. She needed someway to process everything, and writing down her thoughts was usually a big help. She just wasn’t sure that would be enough to help her come to terms with this. At least this will all be over with soon enough, Celestia consoled herself. She shifted, grimacing as her diaper rubbed up against her thighs. I just need to wear this stupid thing for four nights and then I can put this whole episode behind me. That’s not so bad; I’m sure whatever’s been going on these past few nights won’t even be an issue anymore. Twilight needed to pick her jaw up from the floor. Princess Celestia—The Princess Celestia—had been reduced to wearing a nighttime diaper. If it wasn't written by the monarch herself, Twilight never would’ve believed it. And even then, she was still having a hard time comprehending what she was seeing. But the words on the page were plain as day, so clear Twilight could practically see it all happening, right down to a diaper snuggly wrapped around her white plot. The corners of her mouth poked upward at the cute image her head was forming. Wait… cute? Twilight blinked, slipping back to a neutral face. What an odd thought to cross her mind. Could some part of her actually be… enjoying this? She shook her head. That was startling to think about. But perhaps the most startling thing was that Twilight didn’t want to stop reading. Even after all she learned, she still didn’t have answers. She could feel a tick in her brain, writhing in the agony of curiosity. If she stopped now, she’d never learn the truth. It may cause her to never look at Princess Celestia the same way again, but even so, Twilight had to know. She turned the page, heart pounding with equal parts insatiable guilt and insatiable thirst for answers. Her eyes settled on the next entry. It was simultaneously what she dreaded and hoped it would be. Dear Diary, I fear I will be in diapers for quite some time... > The Princess Peed > -------------------------------------------------------------------------- Dear Diary, I fear I will be in diapers for quite some time… Celestia sat in her bed, biting her lip, and tried very, very hard to not cry. She, an alicorn Princess of Equestria who wielded the power to raise the sun, woke up wearing a diaper. A soggy diaper. A diaper she’d no doubt been responsible for the sogginess of. Her head fell in her hooves. “Nooooo…” The cold, damp padding rested against her inner thighs with a sickening feel. Each time she touched them, she shivered. Each shiver forced a different part of her to touch the padding. It was a never ending cycle of shame. Celestia actually sniffled. This couldn't be happening. Wetting the bed was one thing. Wetting a diaper?! She was one step away from foalhood now. What was next, a pacifier? She couldn’t even say it had been a restful sleep. It’d taken forever to slumber with her poofy diaper constantly invading every nook and cranny it could find. And the crinkling. Starswirl's beard, the crinkling. It was muffled by squishes now, but last night it had been a veritable cacophony. The whole castle must have heard. All of Canterlot must have heard. “Nooooo!” Her head sank even further into her hooves, stretching the skin of her face. She’d been awake for two whole minutes and this was already the worst day of her life. Knock knock. She bolted upright, heart lurching. Somepony was at the door! Somepony was at her door while she was wearing a wet diaper! Celestia threw the covers over her damp padding before answering. “Y-Yes?” Her voice cracked.  “Tia? It’s me.” Luna’s voice. Celestia could actually breathe a slight sigh of relief at that. At least it was somepony who knew of her condition. “May I come in?” Celestia’s voice caught in her throat. She couldn’t have Luna find about her wet diaper. She needed four straight nights of dryness to get out of them. The accident around her waist would condemn her to a fifth night in these infantilish garments, bare minimum! She toyed with the idea of teleporting the thing away, so some dump out of town, or on the face of Discord’s statue in the garden, but what good would that do? Luna would be suspicious if she wasn’t wearing a diaper at all. And it wasn’t like the stale stench of urine surrounding her would go away. No, she’d have to own up and admit to wetting her diaper. Celestia blushed. Why, all of a sudden, did she feel like a little filly forced to shamefully admit her accident to her mother? Shaking her head, Celestia chased all those thoughts from her mind. “Yes, sister,” she finally answered. The door swung open faster than she would have liked. Luna strolled in, a confident smile on her face, diaper bag swinging by her side. Celestia noticeably paled, a feat for her. “Y-You didn’t let anypony see that, did you?” She pointed to the bag, unsubtle poofy squares bulging out of its confines. “Tia, honestly.” Luna kicked the door shut as she confidently strolled in. “You sound like a scared little filly.” “I do not!” Celestia smacked her comforter. “Relax, I was discreet.” Luna dropped her bag by the side of the bed. Celestia scoffed. Luna’s idea of discretion was using the Royal Canterlot Voice where a whisper would do just fine. When it came to keeping the diapers a secret, Celestia didn’t have much hope on her sister’s end. “So, now we ask the big question. How do you find yourself this morning, sister?” Her fore legs curled up. No doubt Luna could already smell the pungent stench of urine. It lingered through the whole room, not just by the bed. She must’ve known the moment she walked in. “Wet,” Celestia grumbled. “I see.” Luna’s blue aura pinched the corner of the sheets. “May I?” Celestia squeezed her lips together, but nodded. Her bedsheets peeled back, revealing the shameful display. It was Celestia’s first time taking it all in. A blasphemous stain encompassed her diaper’s crotch. A yellow ocean, coloring the once crisp and poofy padding. This wasn’t wet, this was soggy. Celestia shuddered. But Luna smiled. “Huzzah! Your linens remain unsullied.” She sounded a little too proud of herself. “Luna!” Celestia tried to curl away and hide her shame, but only managed to squish the padding. squish squish squish She cringed.  “Sorry, sister.” Luna seemed like she was choking down a snicker. “I am sorry you were unable to avoid another accident. But I was right, was I not? No more wet bed sheets!” “Indeed,” Celestia grumbled. “Because wet diapers are so much better.” “Well, hopefully you won’t require them for much longer.” Luna’s magic withdrew a pack of foal wipes from her diaper bag. “Now let’s get you cleaned up.” Celestia’s cheeks burned. “I am perfectly capable of cleaning myself!” she squeaked. Luna just sighed. “There’s no need to be embarrassed, sister.” “No nee—” She was in a wet diaper for crying out loud! Now seemed like a perfectly reasonable time to feel embarrassed. “I don’t think you understand how serious this is Luna!” “I don’t think you understand how good this is, Celestia,” Luna fired back. “G-Good?” Luna nodded. “But of course. We’ve found a reliable method to treat your symptoms, have we not? And that’s all we can do as long as you refuse to address the root cause of the issue.” Her ears flicked. “Luna, trust me. I would love to figure out the cause for… this!” she gestured to her yellow crotch. “You think I want to be in diapers?” Luna cocked her head. “So you’ll see the Royal Physician then?” Celestia straightened. The thought of somepony else finding out… of everypony else finding out… “No!” A sigh. “Then will you try to lessen your stress? Perhaps not work so hard today?” “Luna there’s so much to do,” Celestia protested. Her sister threw her hooves up in defeat. “Then I’m afraid you leave yourself no choice but diapers.” Celestia winced. “Not so loud!” She put a hoof out to silence her sister, but leaning in only squished her diaper more. Her wince became a cringe. Luna stifled a giggle. Her magic pulled the comforter all the way back, removing any chance Celestia had of hiding the shameful yellow stain again. “Come now, allow me to help you.” Celestia crossed her forelegs. Luna’s “help” was the reason she was wearing a wet diaper in the first place. But she had to eventually agree that she’d like to get out of it. At Luna’s behest, she found herself lying all the way down on her bed. Cramming her eyes shut, she heard the tapes of the diaper rip off. The soggy padding peeled back, exposing her undercarriage to the air. Magic lifted her hind legs, but before the diaper was slipped out, a wet, cold wipe pressed against her. “L-Luna!” Celestia’s eyes shot open, her blush shooting all the way to her ears. “Be still,” Luna reprimanded the squirming alicorn. “We must get you clean.” Ignoring that, Celestia squirmed. A foal wipe slipped along every nook and cranny of her inner thighs. To make matters worse, Luna seemed content to use her hoof for this part. The contact made Celestia’s stomach churn. It didn’t feel good to have her sister cleaning up her crotch like this. But finally, it finished. Luna slid the diaper out from under her and balled it up. Celestia was able to drop her hooves back down and feel the freedom of nudity. With a poof, the evidence of her accident vanished, and Luna began packing up her supplies. Celestia sat back up, unable to make eye contact with her sister. She just let her face burn while she picked at the edge of her bed sheets. Luna snapped the diaper bag closed and draped it back over her shoulder. “Ohh,” she cooed at her big sister. She leaned in and gave Celestia a hug, the act only making the bedwetter stiffen. “There, there, Tia.” “I do not need to be consoled like a little filly!” Celetia’s voice cracked at that last word, but the message should have gotten across. Luna did at least pull back. “Of course not, sister.” Luna gave a coy smile. “Let us hope you won’t need consoling tomorrow morning either.” How about the next four days. Celestia’s bitterness was palpable, even in her thoughts. She couldn’t believe she still had that long, bare minimum, to put up with Luna’s foalish idea. “Now, up you go.” Luna pulled her up and off the bed, as if she needed help or something. “You have a sun to raise, Celestia.” “O-Of course, yes.” Celestia shook her head. Hopefully the warmth on her cheeks would fade soon. At least the awkwardness of the morning had passed. She didn’t want to be reminded of it anymore! “I’ll see you tonight.” Luna assured her. To Celestia, it seemed more a threat than a promise. “Til tonight,” she whispered as her sister trotted away, oh so satisfied her idea had worked. Celestia could just sigh. Eyeing her diary, she knew there was one bizarre entry awaiting it… Twilight was having difficulty catching her breath. Red-face, taut expression, she could hardly believe herself. The imagery flashing across her mind… the Princess of the Sun having her nighttime accident cleaned up by her little sister… why did it all look so adorable!?” Now it was her turn to shake away the blush.  This was so wrong. Guilt welled up within her. Twilight had already been conflicted about reading something so embarrassing from Celestia’s past… but to find herself actually kind of enjoying the Princess’s suffering? She sounded so ashamed and upset in the pages and yet… Twilight was liking it. “T-Twilight, can we go?” Spike called from across the room. Jolting, she looked up from the book. Spike was now completely surrounded by Star Spiders, his inability to swat them proving to be his undoing. He looked terrified… it probably was time to help him out. And just how late was it actually?  But even so, Twilight really didn’t want to break from the flow of this diary. It was just too good. She had to know what happened next, even if it killed her! ...Even if Celestia killed her. She looked to Rarity for assistance. The seamstress was only halfway through all her curtains, surely she didn’t want to call it quits yet. Luckily, her friend picked up on the look with a wry smile. “Oh, Spikey, why don’t you come over here and help me for a bit?” Her magic levitated the besieged Spike away from the spiders. Having lost the object of their torment, they quickly dispersed. “U-Uh, well… okay, yeah!” And just like that, he was hooked. Twilight breathed again. Flipped to the next page, she prepared herself to dive deeper into the depths of Celestia’s humiliation. For… For knowledge, of course. She wasn’t sure she was prepared for what she would find. Dear Diary, Three nights in a row! I can’t believe it. What did I do to deserve such a fate? And worse yet… I think Luna is starting to enjoy this... Celestia had pulled back the covers to inspect the damage. Her formerly white diaper stared back at her. Nary a corner of it was clean. Yellow, soggy, smelly. It pained her to see so many layers of padding so thoroughly soaked. And the make matters worse, everything was just getting worse! After yesterday’s second wetting, she decided to forgo her nightly tea in the hopes that would help. And it hadn’t. Celestia was quite certain she’d never peed so much before! And to think it all went into a diaper… A knock at the door startled her. “L-Luna?” she probed, magic slipping the covers back over her shame. “It’s me, sister.” The door knob turned, and Luna revealed herself in the doorway. Familiar diaper bag in tow. Celestia whined in the back of her throat. “Alright, let me see the damage.” Lip quivering, Celestia kicked the comforter off in a huff. “Aww, now there's no need to throw a temper tantrum,” Luna chuckled. Then she saw the diaper. “Oh my…” Crossed forelegs, red-faced, Celestia bit her lip. It was the only thing she could do to keep tears from welling up in her eyes. What kind of princess was she? What kind of big sister was she? Every day since the accidents had started, her shame had only compounded. And today was no different. Sensing this, Luna slipped off her diaper bag and took a seat on the bed beside her. “Tia…” “Don’t say anything!” Celestia whimpered. “Just… just get it off me!” Luna tilted Celestia’s head so she could look at her. “Goodness, Tia. You look exhausted.” It was true. Bags were starting to form under the young princess’s eyes. At the rate she was going, she’d age a millenium in a century. “Are you sleeping alright?” Luna asked. The earnest question was a little disarming. Celestia had been getting used to playful jabs and innocent teases come morning. Concern was concerning. “I-I’m fine!” she lied. But the jolt of surprise from it all forced a yawn out of her. “Fine!” she insisted before it even finished. “Tia…” Luna began stroking her mane. It was a trigger they both had developed early on. Their mother always did this when she knew they were hiding something from her. Childhood habits compelled her to answer. “I have not been sleeping well, no.” “Is it your diaper? Is it keeping you up?” Celestia chewed the inside of her cheek. That was part of it. In many respects it was difficult to sleep with a glorified pillow pushing her gait apart.  But another part of it was that she’d deliberately been fighting the Sand Mare. The reasoning was silly, but it should be effective. She couldn’t wet herself in her sleep if she never went to sleep. And just because she hadn’t been able to stay awake so far didn’t mean she couldn’t make this strategy work eventually. If she could just get one dry night in she was sure the experience would snowball her through the rest of Luna’s conditions. “Tia, you have to have your rest,” Luna insisted, taking silence for a yes. “If stress really is the cause of your accidents, then this will surely not help.” Celestia’s pupils shrank. Was that why her wetting was so much worse today? “What am I supposed to do?” She asked, almost accusingly. She pushed Luna’s hoof from her mane. “I can’t force myself to go to sleep!” “Hmm…” Luna seemed to ponder this for a moment. She even scratched her chin, something she never did. “I’m sure I can find something that will help you slumber. Perhaps the Royal Physician can provide you with a sleep aid?” “No!” Celestia shook. “I don’t want him asking any questions.” If that was the thing that led to her diapers being discovered… “Please find something else for me?” “Okay, okay,” Luna was biting back a smile. “Goodness, you’ve been acting more and more like a foal lately.” Celestia’s face exploded. Red. Red everywhere. “Don’t say such things, sister!” Her wings flared, her ears folded down. Luna chuckled, and the whole thing got worse. “I’m sorry, sister. I truly meant no harm by it.” Luna stood from the bed, opening her diaper bag. “Here, allow me to clean you up, okay? I promise I’ll find an alternative to your sleep troubles.” Still rigid from humiliation, Celestia needed a few shaky breaths to calm down. “O-Okay… thank you, sister.” “Of course, Tia.” Twilight was covering up a smile. How cruel of her to side with Luna, but she had to agree. Celestia was acting more and more foalish with each entry. Her childish temper tantrums were a side of her Twilight had never known existed before. As violating as this whole act proved to be, she felt she was getting to know her mentor a little better. She didn’t even need to flip the page for more, there was another entry just below this one, with the same date no less. Dear Diary, Luna has gone too far this time! “I am not using that!” Celestia brought her hind legs together, crinkling her fresh diaper and launching a cloud of foal powder into the air. It stung her nose with the taunt of how foalish it was, but it was still nothing compared to her sister’s proposal. In Luna’s hoof, a pale pink pacifier. She was actually suggesting this. “Tia, please hear me out,” Luna insisted. “NO!” She tempered her voice. No using blazoning her sister’s idea to the whole castle. “Luna, I refuse to use a pacifier. I’m not a foal!” “If you would just listen—” Luna huffed. “And I’m not suggesting you are!” Oh please. First diapers, now this? What else was Celestia supposed to take away from her sister’s ideas?  “Tia, many pacifiers today are specially enchanted. They aid children’s slumber to ensure they get a full night’s rest. This is just a logical solution if you don’t want medication.” Luna held it out closer to her. Celestia’s snout scrunched in annoyance. “But why’d you have to get me a pacifier? Could you just cast the enchantment on a… a sleep blindfold or something?” “I don’t know the enchantment,” Luna clarified. “And I figured a certain somepony wouldn’t appreciate the questions that would come from a princess asking to learn an enchantment meant to help foals.” “So you admit it’s foalish!” Celestia claimed. She was just dodging Luna’s logic, however. “I merely acquired a pacifier and enlarged it for you.” Luna insisted. “It is meant to aid your slumber, nothing more. If we find the enchantment doesn’t work, you can throw it away.” “I would rather never sleep again!” Celestia crossed her hooves, turning her snout up at the device. “Tia, I would love for you to be up during my night,” Luna admitted. “But your sleep is too important.” “I’m not even tired,” Celestia yawned. Luna huffed. Celestia huffed. An impasse. At least, she thought so.  Luna’s hoof was like lightning. She slapped the pacifier between Celestia’s lips with unnatural speed. Or maybe Celestia was just too tired to stop her. But either way, a large rubber bulb pushed her tongue down and her jaw open. The cutesy guard hit her lips. And Celestia started suckling. The motion was so sudden, yet natural, that she almost didn’t notice at first. But when she did her cheeks were scorched with her humiliation. “Ah! Wha— Wuna!” A blue hoof pressed the pacifier into Celestia’s lips. “Nuu!” “This will help,” Luna insisted. “Please don’t be so stubborn, sister.” The almost instinctual suckling continued. A part of the pacifier’s magic? It had to be. Celestia would never do this if she could help it. She slammed her hooves on the bed, whining into the pacifier as her diaper crinkled noisily. She kicked her hind legs in whatever direction her padding splayed them. This was not happening to her! But even as the bout of fussiness erupted, she could feel it being suppressed. Her limbs felt weighed down. Her breathing slowed. The tension in her body started to relax. Though her blush did not dissipate. “There, see?” Luna asked. “In mere moments, you’ll be ready to sleep.” Celestia narrowed her eyes at her sister. But her suckling deepened. It was so rhythmic, she actually closed her eyes for a moment to enjoy it. Luna even removed her hoof, and Celestia didn’t spit it out right away. But she shook her head. This wasn’t right! “Wuna…” “Please give it a try, Celestia. One night.” Luna held up a hoof. “Whether you sleep or not, if you truly hate it, I won’t ask you to do it again.” Celestia furrowed her brow, suckled, and unfurrowed it. “O’tay…” She winced. Between the diaper and the foalish speak her pacifier forced upon her, it was hard to to feel childish. She was a little filly, making deals with her mommy to avoid vegetables for dinner or her afternoon nap. It was peak foalishness! There was no way this could get worse. Her shoulders slumped in defeat. Luna’s face told here there was no getting out of this one. But she was going to hold her sister to it. Tomorrow morning, the pacifier was gone. For tonight… Celestia yawned again. Luna smiled. “I’ll leave you to it, sister. Come morning I hope to see that pacifier still in your mouth!” “Uh-huh,” she mumbled as her sister collected her things. She almost felt like blowing a raspberry at her when she turned for the door. Still suckling after Luna closed the door behind her, Celestia didn’t know what to do. She was angry… but so tired. Her eyes blinked slowly. Even her wavy mane was crawling. But still, her mind was abuzz. Even with the feeling of encroaching fog upon it, she had to find someway to process what had just happened. So she reached for her diary, and wrote until sleep over took her not five minutes later. Twilight watched as the passage trailed off until Celestia must have inevitably fallen asleep. She almost let out a “D’aww”, but held it back. Didn’t need her friends asking questions. She flipped the page, only to frown with actual disappointment. Dear Diary, When Luna woke me up, I learned the most joyous of news! I’m dry! I’m dry for the first time in a week! I’ve never been happier to feel the padding against my coat than I was today. She should’ve been happy for her teacher, but Twilight only found herself frowning. Sure a gleeful, padded Celestia was a cute image in it’s own right, but that wasn’t what she’d been hoping for. She turned the page, frown deepening. Dear Diary, I don’t know if it’s the pacifier, or what, but I’m dry again! Luna could hardly believe it herself! This is truly wonderful! Another page. Dear Diary, Three nights in a row! I don’t know what to say. If I make it to tomorrow morning, I never have to wear these stupid things ever again! Now Twilight was worried. Was this it? She’d broken into the sanctum of her mentor’s darkest secrets. Was this all there was? Sure, it had been scandalous, but Twilight was putting her relationship with the Princess on the line for this! There had to be more to it. She looked to the next page. Dear Diary, No No No No NO NO NO NO NO! A dream startled Princess Celestia awake. What it was about, she already couldn’t say. She yawned into her pacifier, surprised it hadn’t fallen out. As long as she’d used it, she’d yet to wake up at all come nighttime. But it’s effects were still working it’s magic on the startled Princess. She was feeling relaxed again already. Blearly, she felt her body catch up with wakefulness. The sensation of the padding around her waist. The fact that her hind legs were forced into a semi-split. Her aching bladder… “Hmm…” Celestia lowered her eyelids. Without even really thinking about it, she decided to let that one discomfort go. Hiss… Celestia sighed as warm pee rushed out of her diaper. The strain in her hips faded somewhat and it was nice. The way it just gushed out of her, her diaper soaking it all up instantly, just felt right in that moment. Warm padding became damp, and heavy. Sagging only slightly, but feeling far more bulky. “Hmmmm~” She moaned. “Go potty~” In her haze of sleep, she didn’t notice until it was too late. Her bladder wasn’t the only thing giving her pressure. And when her hazy mind gave her body the okay to go, her bowels obeyed. PFFT! Celestia’s eyes burst open. Suddenly, everything she was doing clicked into focus. She was peeing herself! She was about to— FBBBRRT! Celestia pooped herself. Too late to stop it, to relaxed to have managed to even if she tried. One gross log of mush slipped out of her rear, only to be smushed by the weight of her plot on it. Another mudslide wriggled it’s way out of her, ballooning her padding and fighting for dominance in the limited space. The squashed and shifted. Slimy mush coated her undercarriage. Now her diaper was truly sagging. Celestia shot up, biting down on her pacifier. Tears of realization stung her yes. “No no no, pwease!” But the deed was done. She’d messed herself. Sniffling, suckling, Celestia let tears run down her cheek. How could this happen? How could she do this to herself? She was almost free and then… then she just proved she needed diapers more than ever! Head in her hooves, Celestia just whimpered as the steaming mess settled. “Noooo! No no no!” Even her pacifier couldn’t calm her down. She was wide awake now, even if she suckled non-stop, she wouldn’t be asleep again for several minutes. And she wasn’t sure she wanted to go back to sleep as she was right now. It was disgusting! She had to change. Except… she didn’t have any diapers. And she had no idea where Luna kept hers. But if she just took this one off and cleaned herself up, Luna would know come morning something was wrong. She needed a change she just… she couldn’t do it herself. Sniffling, her course of action was obvious. Humiliating, but obvious. And in the aftermath of having willingly pooped her diaper, Celestia just wanted the sensations to go away. She got up, throwing off her covers. Each squishy shift of her diaper made her cringe, but she put up with it anyway. The only thing on her mind was getting into a clean diaper right now. She teleported. And burst into Luna’s room. Her sister was asleep in bed, a rather odd sight to see. Luna preferred to be nocturnal most of the time. But Celestia couldn’t exactly notice the oddity before her. The way her sagging diaper flopped against her inner thighs overpowered any other thought. Whimpering, she shuffled over to her sister. Her waddle of shame was accompanied by squishy crinkles and a violent smell. Even asleep, her sister’s snout twitched in agony. “W-Wuna…” Celestia mumbled through her pacifier. Don’t cry, don’t cry, please don’t cry! “Wuna… pwease… hewp me..” She nudged her sister’s sleeping form. Slowly, her eyes opened. “Celestia?’ Then she gagged. “Oh goodness, what is that stench?” A sniffle. A suckle. “I… I…” Luna sat up, rubbing the sleep from her eyes. Her magic flicked on a lap, illuminating the source of Celestia’s shame. “What are you… oh…” Celestia whined. “I pooped!” “Oh, Tia…” Knowing just what to do, Luna reached up and hugged her sister’s neck. “There there.” she patted her back. “I didn’ mean too!” Celestia cried, softly. She buried her face in Luna’s mane. “I didn’ wanna use my diapee!” “It’s okay, it’s okay,” Luna cooed. “I’m here for you, Tia.” She let her sister cry for as long as she needed, though soon the odor became unbearable. Stale urine, rotten mush. It was an unholy concoction Celestia had dumped in her diaper, and it had to be addressed. Still suckling on her pacifier for comfort, Celestia found herself lying on the ground. Luna had rounded up her supplies with a single spell, and now stood over her sister with a loving smile. “I’ll make it all better, okay?” “I was awmost dere!” Celestia bemoaned. Four nights had been within her grasp and she ruined it. Consciously ruined it! "I know, I know,” Luna cooed. She pulled the tapes open. The full assault of her sister’s mess hit both their nostrils. Two clothespins later, and Luna felt ready to tackle it. Celestia just whimpered, the occasional sob wracking her body. For the most part she just suckled. As the minutes passed, she did start to feel calmer. Wipe after wipe went to war with the mess on her bum. At times it felt like Luna wasn’t making any progress, even as a little pile formed. But eventually she pulled the last foal wipe away, and balled up the biggest accident of Celestia’s life. “There we go, see?” Luna said to her sniveling sister. “Let’s get you a new diaper, okay?” “But…” Celestia didn’t have any ground to stand on and she knew it. She’d failed again to keep her padding clean. And if she pressed the issue, Luna might find out it was done on purpose too. So she complied like a good little filly would for her diaper change. Luna hoisted her legs back up, sliding a fresh diaper underneath. She got a heaping helping of foal powder for her troubles, and even a little rash cream. “As a precaution,” Luna said before sealing her up. And just like that, she had the feeling of a fresh diaper once again. After the mess she’d made, it was oddly comforting. Celestia’s sniffles were a lot more manageable now. “Well,” Luna said. “At least we know it isn’t a lack of sleep causing this.” “Yeah…” Celestia blushed, looking away. “I really do think it’s stress doing this to you. Won’t you give me a few of your responsibilities from now on?” “N-No…” Celestia shook her head. “I can do it. I da pwincess!” Luna frowned. She almost looked like she was stifling her anger. “Tia, you know I can do more. Why must you push me into your shadow?” She gestured to the diaper. “And at your own detriment too!” “I can do it!” Celestia suckled. She had to still prove she was an adult in some capacity. Her eyelids fluttered, the pacifier doing it’s work. Luna groaned, realizing her sister was about to fade. “Fine. I hope you don’t regret this, Tia. Now come on, let’s get you back to your room.” Celestia couldn’t even reply. She was already asleep. But come morning, when her senses fully returned to her, she’d have one heck of a diary entry to write. Twilight was on the third floor. Her jaw was on the first floor.  Sweet Celestia! She couldn’t believe what she’d just read. But the words were from the Princess herself. They had to be believed! Not only had Celestia soiled her diapers, but she’d begged for a change on top of that. Twilight really regretted reading now. Though her curiosity was satiated, her view of the Princess was surely tainted now. There was no going back after what she’d just read. And yet, there was no regret in Twilight’s mind. It was so cruel to take delight out of Celestia’s suffering, but the mental image of Luna coddling her big baby sister was too precious. Worth it? Possibly. Twilight flipped over the page now on the last paragraph written for this diary. Dear Diary, Given the… sensitive nature of my last several entries, I’m quite concerned about the possibility some pony might actually read you one day. So I’ve woven a special curse into your pages, one that only I can undo. Now we’ll see who gets the last laugh if someone other than me opens you up! Twilight’s pupils shrank. A… A curse? She dropped the book suddenly, it’s cover flopping closed. A burst of powerful magic enveloped her. The girls and Spike all yelped in surprise, though none louder than Twilight. When the light faded, they were all looking her way now. “T-Twilight?” Rainbow Dash was snickering. Coming to her senses, Twilight saw what had been done to her. A massive, poofy diaper encased her hips. A yellow onesie locked it in place, a familiar sun emblem emblazoned on its chest. And a matching pacifier filled her mouth. One test from her lips told her it was not coming out any time soon. Lastly a bonnet swallowed her head, her mane rearranged into little twin tails that spilled down by her neck. “Darling, what are you wearing?” “Aww, cute!” “Um.. that’s… oh my…” “Sugarcube, what happened?” “Holy crap, Twilight!” She wanted to shrink away into nothingness, then and there. But she couldn’t do anything, not even fly away, her wings trapped under the onesie. She stumbled back, tripping due to her wide gait. Her fall showed off her poofy rear end a little too well, and none of the girls could hold back confused giggles. Twilight whined into the pacifier. If the diary was to be believed, there was only one pony who could get her out of this getup. And she was not going to be happy with her, at all. If Twilight ever wrote her own diary, this was not going to be an entry.
