A Very Desperate Day

Equestria, the land of ponies, friendship, and magic, carried with it more than just the simple basic details of a kingdom and its inhabitants.

The land was governed by two monarchs, using the title “princesses.” Those were Princess Celestia, and Princess Luna, both a somewhat godly race by the name of Alicorns; each morning and each night, they raise and lower the sun and the moon to usher in the passage of time. Aside from that main duty, they both have their own “courts”, sessions where they answer questions and concerns from the citizens of Equestria in their throne room, each of them having their court at their fitting time of the day - Day Court for Celestia, Night Court for Luna. (Although, Night Court was only held on a few exclusive dates; Luna’s usual duty would be searching through the dreams of ponies to prevent nightmares and take care of other dream-related issues. The world of dreams was like a magnet for unruly magic.) It was always chaotic and hectic; running an entire kingdom was a big responsibility for two equines.

And, of course, it was no uncommon thing for schedules to require changing and rearranging to accompany the constant bend and weave of mounting tasks.

Now was the time for Day Court; usually, Princess Celestia would handle this on her own while Luna slept, but the schedule was a little different for today. Instead, both sisters sat on their respective thrones, awaiting the incoming tide of queries and duties.

Luna yawned, covering her mouth with a hoof bearing a silver shoe, her horn glowing as she used magic to brush her dark-purple fur. Her mane and tail, both waving naturally in the air as a matter of her magic power, resembled the night sky in its dark blue hue, along with the reflection of many small stars. “Sister, would you please remind me as to why I am required to stay awake for this?” Luna asked, not hiding her displeasure. “I am exhausted from exploring the dreams of so many ponies last night.”

“Sorry, Luna, but duty calls. There are many tasks that require both of our attention at the same time; I scheduled them all for today. This way, we can knock them all out together, and not have to worry about them for a while.” Celestia’s own snow-white fur was already pristinely washed, brushed, and cared for, as was her tail, a combination of pastel colors that floated similarly to Luna’s. She sipped from a cup of tea sitting on the ground next to the throne, magically lifting it to her mouth. Rather than having elevated seats, the thrones consisted of velvet cushions on a red carpet, with the back of the throne holding up the royal aesthetic. The cushions were as soft and fluffy as pillows. “I’m sure it won’t take that long.”

“Hmm… this is most inconvenient, but your plan is sensible. I will see to it that we are able to effectively perform our cooperative tasks.” Luna straightened herself up, fully groomed. “When shall we commence?” It had been only a few months since Luna had returned from the moon; she’d mostly settled back into her position, but still, there were kinks to iron out.

“In a little bit. Have some more tea before we begin - I made sure to have the chefs prepare an extra sweet blend for today.” As she spoke, a maid filled both of their glasses, though with two different teapots. “Though, I made sure to request a darker one for you.”

“Thank you,” Luna said, happily sipping the tea; the maid was quick to refill it once again. “I appreciate it.” However, as she drank, the princess of the night felt a small, nearly insignificant pang in her lower body; something located around her bladder. It seemed she’d drunk more tea than she expected, and the caffeine was getting to her, especially affecting her urinary system. “Sister, I believe it would be best if I were to quickly… freshen up before the first guests arrive—”

“Oh, look at that!” The daytime princess set her cup down, standing at attention. “Our first guests are about to arrive. Make sure you look your best, Luna!”

“Oh, right… of course.” Luna straightened her back and sat with her head held high; she was royalty, and of course, a certain stance was expected from a monarch. Still, her height was far shorter than Celestia’s, due to her lack of growth while banished to the moon; although she still stood taller than the average adult pony, her stature paled in comparison to Celestia’s. This was in contrast to her personality - she was known to be a bit more abrasive and cold than the friendly and caring Celestia, though of course, Luna was far from lacking the approachable quality that any Equestrian princess was expected to have. Still, she had progress to be made in that department. “What exactly is our first engagement?”

“Oh, just a little meeting with a representative from Manehatten. It won’t take long… probably.” Celestia smiled her usual smile.

“I certainly hope you are correct,” Luna murmured, barely loud enough for the fellow princess to hear.

Although Celestia’s smile held its expected warmth, it didn’t reflect her true current emotions; in fact, her thoughts that day were mischievous and sinister. Although everything she’d said so far was true, she had more plans for the day than just regular princess duties. In truth, Celestia had always had a certain interest in seeing ponies, especially mares, in situations where they were desperate to urinate, but were completely unable. Luna was a natural target for these desires; although they were called sisters, this was only a title, and they lacked a true blood bond, making it so Celestia held no reservations about her current actions. She’d noticed fully that Luna had to use the bathroom… and she planned to make sure that Luna never got the chance, not until she let it out on the very throne she was currently seated upon. Everything was perfectly set up for this, even down to the incoming guests. Her plan would go perfectly.

“Oh, you know, Luna, I was thinking about something recently. Do you remember our trip to the Crystal Empire a while back, before… well, you know.” Celestia waved her hoof in the air. “I was just thinking about it recently - I found a picture of you and me in front of the Crystal Heart.”

“We had many visits to the Crystal Empire, dear sister. Remind me of the details of this one?”

“Hmm… well, honestly, I think what I remember the most is the chariot ride over. It had just been freshly cleaned, I believe, and you looked a little bit nervous about it for some reason, but we really had to rush out the door.”

“Oh… that one. Yes, I remember,” Luna said, lowering her head a bit; she wished she didn’t remember it so well, honestly.

The royal guards, mares and stallions clad in golden armor, stepped aside from the throne room doors; before Celestia could continue, a minty-colored stallion in a full business suit, complete with a red tie and heavily gelled mane, walked into the building, followed by a similarly-dressed mare wearing a pair of sunglasses. This was business as usual - both princesses were accustomed to dealing with guests such as this on a daily basis, one after the other, no matter what their request or subject for discussion entailed. From issues requiring serious and laborious solutions, to simple complaints or requests that could be fulfilled or dismissed in only a few words, the princesses were always ready.

Or at least, almost always.

Princess Luna had multiple princess-related characteristics she needed to build up, and a particularly difficult one was her bladder. Sitting on her throne for many hours on end required her to hold in her need to use the bathroom, especially since she had a reputation to uphold, and speaking of urination did not do that reputation many favors. Unfortunately for her, she already needed to go quite badly, but this Manehatten representative was strapped in for the long haul.

The two sisters and the representative went back and forth on a number of issues; slowly, Luna’s bladder seemed to fill more and more, to the point where it was reaching capacity. She’d damned herself by drinking so much tea, she thought, but it was too late to go back now. She just needed to get through this first meeting, and then, she could easily get Celestia to give her some time to relieve herself…

…but for now, she had to do everything in her power to keep it in.

The royal posture, thankfully, allowed for a little flexibility here; she pressed her thighs together whenever she wasn’t being focused on, creating pressure to calm the aching of her bladder, though it barely helped. She rubbed them together as quietly and discreetly as she could, trying not to let the rest of her body move with the motions; it wasn’t so bad yet - as long as she could keep this up for a while, she’d make it to the end of the meeting.

Though, she had to wonder why she needed to be involved in this in particular - it sounded like an issue perfectly suited for one princess to handle… and at this point, she couldn’t help but think much more about her current bladder issues, rather than the discussion at hand. Soon, she was shifting her position every few seconds, trying to make the movements unnoticeable, but it seemed there was no comfortable way for her to sit. It always felt like she was pressing on the bladder, squeezing it with her body, and not in the way that helped to dull the constant aching. She winced visibly, though she was quick to hide it; the pain was increasing, dull and pounding. One of her back hooves idly tapped against the ground beneath her, trying to distract herself; sitting still with a full bladder was a monumental task, even when sitting still all day was basically her job. If anything, that just made it more difficult; her legs were starting to fall asleep.

“We are severely lacking funding for this project; with the paltry amount you are providing, we have no hope of completing it in a timely manner.” The representative was clearly annoyed; he turned his attention to the other royal mare, hoping to get some support from another source. “What about you, Princess Luna? Don’t you see that this social work project is worth a little bit more funding than what we’ve been provided with?”

Luna snapped out of her bladder-focused stupor; she quickly racked her brain, attempting to come back to the topic of the conversation and recount it, but she realized here that she’d been entirely unable to listen. Even now, the constant pounding ache was making it difficult to think; she had to spend precious focus just keeping her bladder from leaking. Once a leak started, it wasn’t going to stop. She looked to Celestia briefly; the daytime princess looked back and gave a simple nod. The princess of the night raised her head, attempting to stand tall, even though her hind hooves were beginning to quiver. “I believe you’ve already received your answer from Princess Celestia. Our royal reserves must be used sparingly, and we need to make sure a certain amount is available in case of emergency. I would suggest considering local fundraising - consider appealing to the ponies who would most benefit from your project for donations.”

“Yes, I’d also suggest following Luna’s advice. I’m sorry we cannot contribute more, but I believe this is the end of our discussion for today. If you’re in need of accommodations for the day, speak to the maids outside - we’re happy to offer a few of our spare rooms. Otherwise, safe travels.” Celestia’s tone was motherly and warm, but at the same time, final and strict. When she said the discussion was over, that meant the discussion was over - you didn’t argue with a princess.

“Hmm… well, so be it. Thank you for your time.” The representative walked away with the accompanying pony, likely his agent.

Luna let out a quiet sigh of relief as soon as they were out of earshot; that had taken nearly 45 minutes. Her bladder felt like it was about to burst; there was only so long she could rub her thighs together before it gave out. The cushion she sat on was expressly soft and comfortable, as well as quite pillowy, but that was just making it harder - it was too relaxing, putting her body into a state of calm that didn’t match the current emergency in her urinary system. Luna turned to Celestia. “Sister, could you potentially allow me a moment to—”

“Hold that thought, Luna - we don’t have much time before our next guest. I need to brief you before our meeting starts.” A royal guard approached the throne with a silver tray in his mouth, on which was a stack of papers. “It’s just going to be a brief meeting with the Apple family, but I want to make sure you have a good rundown of the situation.” She magically passed the papers to her sister; Luna attempted to receive them with her own magic, but the focus required to perform such a feat quickly proved disastrous for her bladder. The moment her horn began to glow, it immediately stopped, the princess forcing her front hooves between her legs to hold her urine in. Her eyes widened; for just a moment, she’d felt a rush of liquid going straight to where it would release itself. She was only barely able to stop that leak. She breathed a sigh of relief, looking worriedly down at her lower region, as she held the papers in the bend of one of her front legs, the other one staying pinned to her crotch.

Celestia tilted her head. “Are you doing alright, Luna? You look a little bit stressed.” Of course, the daytime princess knew exactly what the issue was… and she had committed the little scene that’d just played out in front of her to memory. Suddenly, she remembered something she’d said earlier… and a fiendish idea formed in her head. “You looked just like that in the chariot ride I mentioned earlier! I remember, you really needed to relieve yourself the whole time, but you’d forgotten to do it before we left, so it made for quite the uncomfortable trip.”

Luna blushed, trying to avoid Celestia’s eyes; that moment had been one of the most embarrassing times of her entire life, something she frequently tried to forget. “Well, it would not have been so much of an issue if we had brought the chamber pot as we usually do…” Luna responded, reading the papers she’d been passed, almost hiding behind them. “I don’t know why we didn’t already have one in the chariot.”

“Somepony probably just forgot to put it back in after cleaning it. At least we won’t be making that mistake again!” Celestia chuckled.

“I would hope so.” Luna skimmed the papers; the situation seemed, honestly, entirely normal and usual; she wasn’t sure why her sister found it necessary to read up on it. “I have an understanding of the situation with the Apple Family; it seems to be what we’d normally expect. Now, I think it would be prudent if I were to quickly… brush my mane before they arrive,” Luna said, stepping off of her cushion.

“Oh, I think your mane looks just fine, Luna!” Celestia magically took the papers back; Luna tried to hide her frustration. “Also, I believe they’re almost—”

As if on cue, the royal guards opened the doors; in walked the older, apple-green pony, Grannie Smith, accompanied by the much younger pony, Applejack. They both walked much more casually than most guests to the castle would, each of them having their own familiarity with the princesses - Grannie Smith was the closest pony to the princesses age-wise, and Applejack had met Celestia and Luna multiple times due to her close friendship with Celestia’s pupil, Twilight Sparkle. Still, they both bowed when getting closer.

“At ease,” Celestia quickly said. Applejack pulled behind her a cart with a keg on it, as well as two wooden mugs sitting on top. “It’s so great to see you, Annie! And I’m also delighted that you’re accompanying her, Applejack. It will certainly be beneficial for you to observe our business dealings so you are prepared to take over when the time comes.” Celestia seemed genuinely happy; only Luna and Twilight could really tell the difference between Celestia’s fake happiness and her genuine excitement. “I’m sorry to make you both travel all the way out here.”

“Oh, don’t worry ‘bout that, Tia - you don’t need to be so formal wit’ us,” Grannie responded, smiling toothily. “We do gotta keep things short, though - Big Mac and Applebloom are settin’ up a stall in the market already, we gotta get our sales goin’ while we’ve got sunlight left to burn. Give it to us straight - how much cider were you wantin’ this year?”

Luna bit her lip ever so slightly, trying to make it imperceptible; she could hear the sloshing of cider from the barrel Applejack had pulled in, and the sound only aggravated her aching. She pressed her thighs together again; it was a struggle to maintain her posture. She constantly had to pull herself back upright; she wanted to curl in on herself, put as much weight against her bladder as possible to keep it contained, but that wouldn’t look good in front of the guests, of course. Both her hind legs were now lightly quivering; her eyes kept going back and forth from her guests, to the bathroom that sat just to her right, behind a door normally kept out of view by a curtain. It was so close, yet so incredibly far away. She slowly pulled her front hooves closer; she rubbed her thighs together harder and faster, even taking a hoof and massaging them, trying to will the urine to retreat. Again, it was impossible to focus on her guests, but at least she had the promise of a quick meeting, going based on Grannie Smith’s words…

…or at least, that’s what she’d thought. But of course, being old friends, Celestia and Grannie Smith’s conversation went on for what felt like hours, even if it was technically only 30 minutes. Still, 30 minutes is no short amount of time to hold in a bursting bladder; Luna would’ve felt somewhat comfortable being less regal in front of Celestia’s longtime friend, but unfortunately, Applejack was similarly bored, which was causing that earth pony to look around a whole lot, making it so Luna couldn’t leave herself exposed without drawing her attention.

She bit the inside of her lip hard, trying to distract herself from the pounding aching that was only getting worse with every moment; as she discreetly rubbed her thighs, she could feel something between them. It was a lump, a bulge - her bladder was so full that it was physically showing itself to the outside world. She quickly put a hoof to her mouth to muffle a whimper; she’d never had that happen before, not since the chariot ride. This was miserable. She tilted her head back and squirmed, repositioning herself over and over and over, the cushion suddenly feeling so incredibly uncomfortable against her rear.

“Is something the matter, Princess Luna?” Applejack suddenly asked; Luna quickly snapped to attention, eyes wide.

Luna cleared your throat. “I beg your pardon?” She asked, a light blush on her cheeks that she couldn’t seem to hide.

“I was just asking if you’re doin’ alright - you seemed a bit out of it,” Applejack repeated.

Celestia muffled a giggle with a hoof; Luna bit her lip to stop herself from showing her displeasure. Applejack was the element of honesty, sometimes to a fault. “I’m doing quite fine, although I appreciate your concern,” Luna responded, trying not to sound too aggressive.

“Don’t worry Princess Luna, we all have our off days. Maybe this will cheer you up!” Applejack grabbed the two mugs from the top of the keg and began filling them up with cider straight from the barrel. “We were wanting to let you have a sample of the product before you put it into storage.”

Celestia smirked, again, hiding it behind her hoof. She didn’t plan this at all, but things couldn’t have turned out better. Admittedly, she was also a bit amused when she realized that Applejack was mostly just trying to move things along so she could help her siblings with the sales. “It’s always a pleasure to enjoy apple cider from the Apple Family - we’d love to.”

“Oh, I’m… actually not feeling particularly thirsty, but thank you,” Luna said with a fake smile, her bladder pulsing at the very notion of drinking something. That would be like pouring water into a full glass and expecting nothing to leak out.

“Oh, come on, sister - I can’t remember the last time we’ve had a chance to try this!” Celestia floated both of the full mugs of cider over, taking one in her own hooves and putting the other in front of Luna, forcing the nighttime princess to grab it. “We shouldn’t turn down their kindness.”

“Mmm… of course,” Luna responded, struggling not to show her distaste as she stared at the cider. It was a dark yellow, with foam at the top; the color and texture gave her a horribly-timed reminder of what urine looked like. Her bladder pulsed; she leaned over, suddenly feeling her own urine wanting to leak out at the simple sight of the liquid sloshing around in the bottle. She held it back, but only barely.

Of course, Celestia was already drinking it; Applejack stared at Luna with an expectant, excited expression. How could she say no to that? Especially after Celestia had basically forced it into her hooves. She gulped, closed her eyes, and began to drink, chugging it as fast as she could, biting the bullet hard and painfully. It instantly made things worse; her bladder’s bulge seemed to visibly increase, the aching sensation and pain doubling. She shivered involuntarily; it was really getting bad. Her back legs both tapped against the ground, the light movement serving as an almost entirely ineffective distraction; she squirmed and moved and repositioned over and over, feeling as though she was only seconds away from losing control at this point.

“Wow, Princess Luna! I had no idea you were such a fan of our cider,” Applejack said with a chuckle. “I can give you a refill to keep for the rest of the day, if you’d so like.”

Before Luna could answer, Celestia spoke for her. “She’d love that, and I would as well!” She floated both mugs back over; Applejack happily filled them back up.

“You can keep the mugs - consider them a little gift from the Apple Family,” Grannie Smith added, as the mugs were floated back to the princesses, entirely full, making Luna feel like she was going to faint. Just looking at the dark yellow liquid again made her head feel light. She breathed in through her nose and out through her mouth, trying desperately to keep her body functioning normally and resolutely so she could get through this without making a mess right then and there. “We oughta head out, Big Mac and Applebloom could probably use some help out there.”

“Thank you both! I hope you have some profitable sales,” Celestia said, waving goodbye as she sipped the newly filled mug of cider.

“Yes, good luck,” Luna added, looking scornfully at her own mug as the two apple-picking ponies turned and left. She gently floated it down onto the ground, and slid it a bit far away, hoping she could avoid the scent and sight that were both making her hind legs quiver so fiercely.

The door closed behind the two ponies; after taking another sip, Celestia spoke. “Be careful, Luna - we don’t want to spill any cider on these cushions. You know how hard it is to clean any liquid off of these things, and the carpet, as well - it’ll take a lot of magic and time. Just like…”

Less than a minute after the two other ponies had left, a new one burst in, quickly running up to the princesses with her head low, breathing heavy. “I’m so sorry, Princess Celestia and Princess Luna - I completely overslept!” Sunscribe spoke, a quill, a bottle of ink, and multiple rolls of blank parchment paper following behind her, floating magically. She was the scribe for Canterlot Castle; her fur was a lavender hue, similar to Twilight Sparkle’s, but more pastel and light. Her hair was a pink gradient, and her hooves were covered with silver shoes, similar to Luna’s, but slightly less ornate.

“You’re fine, Sunscribe - we can hardly blame you for sleeping in a bit after… how long did it take this time?” Celestia questioned.

“Um… two months and thirteen days, I believe,” the scribe responded, setting herself up on the left side of the throne room, near a wall, where she would be noticeable, but she wouldn’t get in the way. “How long was I asleep for?”

Luna responded, “Twenty-seven hours. I checked on your dreams last night; I must say, they were… somewhat unexpected.” The dream-leaping princess smirked slyly. “I didn’t realize I made so many appearances in your fantasies~”

Sunscribe blushed, eyes widening; she immediately hid her face behind the scroll. “P-please don’t talk openly about my dreams, Princess Luna!!” Her voice cracked multiple times in that one sentence as she remembered exactly what she’d been dreaming of.

“Do not fear, Sunscribe - I will wait until the evening to share the details with Princess Celestia.” She chuckled at the scribe’s expense, though immediately, the dominant, in-control persona she was putting on waned with a sudden, painful reminder from her bladder. She gasped and leaned forward, immediately pressing her hooves to her crotch, her face going red as she just barely stopped a sudden leak. “I believe now would be a good time for me to freshen myself up,” she said, once again stepping off of her cushion.

“Oh, hold on, sister - let me finish what I was saying earlier,” Celestia said, knowing exactly what she was doing. Luna froze in place and looked at Celestia, still not realizing that her sister was fully aware of what was going on; the nighttime princess was far too concerned with her image to just tell Celestia that she needed to pee. Her legs visibly and clearly wobbled; Celestia tried not to stare lustfully at the bladder bulge. “I was going to say, try not to spill any of your cider on the cushion or on the carpet, you know how difficult it is to clean it off. We certainly don’t want a repeat of the chariot~” Celestia grinned as though she were simply recounting a charming story. “I remember, during that long trip and all of those failed attempts for us to stop and let you relieve yourself—”

“Tia, please!!” Luna quickly interjected, her face entirely red.

Celestia chuckled. “Oh, don’t be so embarrassed, it happens. I just wanted to say, we should certainly be careful to avoid getting anything on these carpets and cushions, especially anything with a particularly strong smell.” Celestia sighed fondly, nostalgically recounting the story even further. “I remember, on that chariot ride, you kept asking if we were getting close while rubbing your thighs and constantly looking from side to side, saying how badly you needed to use the bathroom. We kept looking for an unpopulated area to stop, but it would’ve been such a disaster if some pony were to see one of the Canterlot princesses peeing in public - you ended up just having to hold it in the whole time! I remember how badly you squirmed.”

Luna could feel her face heating up; even having just Sunscribe hearing this story was embarrassing enough. “Sister, please, I don’t need to be reminded of that memory…”

“Aww, but I thought it was cute! I haven’t seen you so off-guard in so long. I almost wish it would happen again.”

Luna heard the sound of a quill scribbling. “Sunscribe, stop writing.”

“Oh, oops,” Sunscribe said, chuckling nervously. Her horn glowed; about a page’s worth of the scroll gently ripped off, filled with the words the sisters had just exchanged, including the details of the nighttime princess’ previous misadventure. The moment Luna turned away, the scribe hid the paper underneath of her - it wouldn’t be needed for the royal records, she just wanted it for herself.

“Stow your quill and save your ink for the more… important matters.” Luna continued walking off the throne. “Now, if you will excuse me, I need to hastily freshen myself up. I will return before the next guest arrives.”

And of course, immediately as Luna took a shaky step off of her cushion, the door creaked open. She shot right back to her spot, immediately burying her face in her hooves in dismay. She went right back to her squirming and rubbing of thighs; of course, after all of this, it was worse than ever. Being reminded of the past incident, combined with the warning about the cushion and the carpet… having an accident here would be disastrous for a number of reasons.

A granite-orange earth pony walked into the room, clutching a paintbrush in his mouth and hauling a small cart behind him featuring a canvas, easel, palette, and bottles of paint. His cutie mark was a golden frame that would belong over a piece of art. “Good afternoon, Princess Celestia and Princess Luna,” he greeted, his tone low, his accent matching the upper class of Equestria. He bowed before them, placing the brush in the cart.

“Welcome, Canvas Black. Thank you for making the journey all the way here for this; I’ve been very excited to see your work.”

“The honor is all mine,” he responded, lifting from his bow and assembling his equipment. “I believe this portrait will take at least an hour, at least, for the in-person portion. I plan to add some finishing touches back at my studio. Do either of you need any time to prepare?”

“Sister, what is this?” Luna asked, confused, her brow furrowed.

“Oh, I totally forgot to tell you - we’re getting our portrait painted! That was the most important thing for today, actually. Don’t worry, you just have to sit still for an hour, and you look great.”

“Oh no…” Luna glanced at her bulge; it had grown to the point where it was incredibly visible. She struggled to hide it behind her hooves and thighs. “I think it would be wise if I were to take some time to prepare…”

“No no, there’s no need for that, Luna - you look perfect as is. Let’s not waste any of our guest’s time. You may begin, Canvas Black.” Celestia slightly straightened up, assuming a somewhat more royal position, with a calm, neutral expression. Her pose was elegant and royal, as to be expected.

“Understood,” the artist responded, dipping his paintbrush.

“Tia…” Luna went to argue, but the artist was already about to begin; she quickly straightened her back and assumed the same royal posture, but it was far more difficult than usual. The bladder bulge was getting in the way, of course, and she just couldn’t find a stance where she could keep it hidden. And of course, her need to pee made it difficult to maintain any certain pose at all - she tried to hold straight as the artist began his work, but she couldn’t help but at least rub her thighs together a little.

The artist went to work; every stroke he made was slow and deliberate, as was to be expected of someone of his caliber and skill. He poured his passion into his craft. Normally, Luna could respect such a level of dedication and artistry, but at that moment, it was driving her insane. Everything in the room was stunningly quiet; only the very quiet sounds of Canvas Black painting could be heard, the dipping of his paintbrush into the paint making Luna only more desperate, even though that liquid was of such a different consistency. She tried to distract herself and think of something else, but her mind always went right back to her bladder, either because of the aching pain emanating from it, or because she found herself suddenly having to concentrate on stopping a leak. She felt like her body was actually physically heavier than normal, and more bloated; it was miserable.

After only ten minutes, holding still was going beyond unbearable and getting impossible. She rubbed her thighs just a little bit, just every few seconds, the pressure giving a slight relief that was quickly canceled out by the rushing of her urine through her system. The inside of her mouth sat clenched between her teeth, but even the light, distracting bite from that was overridden by her body’s constant, desperate reminder of the poor state of her bladder. Her eyes traced every single thing in the room, from the bathroom to her right, to the still-full bottle of apple cider that so strongly resembled urine, to the painter and his paint, to Celestia and her calm, entirely unbothered attitude and pose that made Luna envious of how easy it must’ve been for her to just silently sit and be painted.

At one point, she heard a shuffling; her eyes darted to Sunscribe as the scribe gently set down her supplies, seeming to feel no need to actively document what was happening considering the lack of any actual conversation. She then walked to the bathroom, opened the door, went inside, and locked it behind her. Every sound associated with it, the door opening and closing, the hoof steps, the lock clicking into place, drove Luna mad; she so desperately wished that she was the one going inside that bathroom right then. She could picture Sunscribe relieving herself; she could practically hear the pleasant sigh of relief in her mind. It was enough to make her hooves quiver, her bladder pounding and pounding and pounding, as if it was saying, “Why can’t you do that right now?”

And to make it even worse, the silence in the room and Luna’s proximity made even the muffled sounds from inside the bathroom audible. She could just vaguely hear the sound of urine trickling into the water of the porcelain toilet bowl; the more the princess tried to ignore it, the more she ended up inadvertently focusing on it. And it was so long, too - Sunscribe had slept for so long, it only made sense, of course. The sound eventually stopped, only to be followed by the quiet flush of the toilet; the princess immediately pictured the yellow waters swirling in the bowl, being taken down the drain, the sound of all that water flowing into the sewers making her heart thump, her breaths getting shaky.

Sunscribe exited the bathroom, smiling happily; Luna glared at her with intense envy. The door stayed open for just long enough that the princess got a short look at the toilet inside of it, before the door closed itself, an accurate and biting metaphor for what Luna was going through at that moment. The princess of the night turned her attention back to the artist; how long had it been? She’d lost track. That was the worst possible outcome; looking around, she couldn’t seem to find a clock within view of her current position, not without turning her head and ruining the portrait. That uncertainty made it hellish to sit and wait with a full bladder; ten minutes might have passed, or it could’ve been less than five, or more than 50. It was entirely unpredictable. Of course, she couldn’t see the portrait itself, either; for all she knew, he was just about to finish up, or he’d only barely started the outline.

Her bladder bulge pulsed and pounded; her hooves quivered harder against the cushion and the floor. A sudden rush of urine went through her body, a desperate attempt from her own subconscious to empty her bladder’s contents, and she quickly stopped it, focusing as hard as she could, sweat now beading on her forehead. She couldn’t help but squirm, shifting positions to relieve the pressure, her face turning red yet again from embarrassment and nervousness, her lips quivering just as her slit was.

The painter dealt with it for a little bit, but Luna changed her position over and over; even as she tried not to, her body forced it out of her, making every shift a dire, absolutely necessary action to prevent a leak. Soon enough…

“Princess Luna, please, I must ask you to remain still, else the portrait may end up being off,” the artist scolded; Luna immediately went back to her former position and maintained it. Her face burned with humiliation; Celestia’s lips curved ever so slightly into a smile. She wanted to run and hide her face under her blankets… or at least, run to the bathroom and relieve herself behind a closed door. Her eyes glanced to Sunscribe, who immediately hid her face behind the scroll, clearly hiding her own enjoyment of the situation. “Thank you. I am nearly halfway through,” the artist spoke.

Nearly halfway!? Luna was desperately hoping he was at least close to being finished, but he wasn’t even at the halfway mark! This was a torture worse than anything she’d ever experienced before, and now, she had to hold entirely still. She fought her body, constantly forcing it to stay in position, stopping the instinctual squirms; still, she couldn’t keep her legs from shivering and shaking, which seemed to annoy the artist, but he thankfully made do. Luna began to follow his gaze; it seemed like, for a moment, he was staring at her bladder bulge. Surely, he hadn’t noticed it… right? This was true torment - she was trapped, and the metaphorical chains around her now were far more strong and resilient than any real chains or bondage that could’ve been placed upon her.

At this point, Luna looked down to the carpet and cushion; Celestia’s words echoed in her head. It would be so hard to clean if anything was spilled on it… The cider would be a threat to it, sure, but Luna could easily think of something far worse, far harder to clean out… and so much more embarrassing for her. If she were to have an accident now, she’d be totally stuck just pissing and pissing until it was over; once she leaked, she wouldn’t be able to stop until her bladder had emptied itself in its entirety. It would certainly be long, and there would be so much urine to spill; she’d soak the cushion so thoroughly, it would be as if she’d left it out in the rain, and the carpet would be so damp that stepping in it with a hoof would make a loud, wet squishing noise. She’d never live that down - even if nobody was there to see it except for Celestia and maybe Sunscribe, the maids would easily be able to figure out what happened. Her soaked cushion, the trail of urine, it would all make it obvious, like following the tracks of a wild animal.

The painting stretched on and on and on; it felt truly endless. Luna couldn’t help but constantly imagine the stain she’d make if she had an accident. There was nothing to distract her from delving into the worst possible scenario again and again, nothing but the constant pain from her bladder. Eventually, though, it finally ended; the painter made his last stroke, and nodded to himself in satisfaction, putting his brush down. “I have finished, for now, at least. I’ll be taking this back to my studio to put the finishing touches on, as I said earlier. I’ll be sure to have it sent to you the moment I am satisfied, hopefully by tomorrow.”

Luna finally leaned over, letting out a breath she hadn’t realized she was holding in; she began to squirm and reposition herself yet again, as if making up for all that time she’d sat still. Without any regard for the presence of the artist, she pressed her front hooves up to her slit, pushing hard, squeezing them between her thighs tightly. She swayed lightly from side to side, tapped her hooves on the ground, everything she could possibly think to do to hold back her bladder. It hadn’t gotten even a single bit easier; she could still feel it pounding, aching, her urine rushing to her pussy over and over and over, constantly having to hold it back.

“Thank you so much, Canvas Black. Is there any way we could see it in its current form?” Celestia asked, breaking out of her posture as well. The task of sitting still for an hour was more of a relief to her than anything else - it was a nice break from having to do something actually taxing, like talking to diplomats or whatever else.

“I’m afraid not - I’d rather you not see it until I’m absolutely satisfied with the result. Do not worry; I will make sure it is well worth the wait.” He packed up the rest of his things back into the cart, not carrying the brush in his mouth this time. The painting laid on top of it all, face-down, wrapped in some kind of preserving material. “Thank you for your time, Princess Celestia and Princess Luna.”

“It was our pleasure,” Celestia responded; Luna couldn’t have disagreed more. The door closed. “Well, that was certainly difficult, wasn’t it, sister?” Celestia laughed in a friendly manner.

“Indeed it was, dear sister,” Luna responded through gritted teeth; she was hunched over her bladder bulge, holding it in the absolute best she could with every part of her body, her eyes looking at it with worry. She honestly couldn’t believe she’d managed to hold it this long; she wasn’t even sure if she’d manage to make it all the way to the bathroom if she stood up and started walking now. Her legs were shaking so much that she worried she might fall over; she could feel pins and needles in them, the prickling pain of her limbs falling asleep, which would only make things more difficult. She was quite certain that one wrong move could easily end in her bladder giving out. She wanted to tell Celestia that she was going to get up and “take a moment” or something like that so she could finally excuse herself, but she wasn’t sure if she could even handle that at this point - her fear of an accident paralyzed her, paradoxically preventing her from actually relieving the potential cause of that accident. Still, she opened her mouth to do so, but then…

“You know, I don’t think I’ve seen you struggling to sit so much since that time on the chariot. You were acting just like you were earlier, and like you are now, actually. Trying so hard to sit still, but you kept squirming and moving back and forth, repositioning yourself, pressing your thighs together, it was so cute.” Luna turned to interrupt and stop her sister from recounting any more of the embarrassing tale, but as she turned, she immediately had to focus back on her bladder, on stopping yet another imminent leak. Celestia continued, “I remember how embarrassed you were when you finally couldn’t hold it any longer! Your face looked just like how it does now, all red; I remember you just sitting there with your mouth open, looking down between your legs as urine just kept pouring out of it, all over the seat, trickling along your hind legs. I had to stand up for the rest of the ride, but there wasn’t enough room for both of us, so you had to sit in it the whole time. I felt so bad for you, but I couldn’t stop laughing about it - seeing you so shy and embarrassed was just so out of character and so precious.” Celestia let out a warm, kind laugh; she still acted like it was just a happy little memory. “I remember, the whole time after we landed, you were still so bashful!”

Luna wanted to disappear, she was so embarrassed. Her lips quivered; she accidentally let out a barely audible whimper, both from the humiliation and her struggle to continue holding her bladder. She wanted to use her magic to just teleport under her covers and hide, or even better, into the bathroom for some relief, but she knew she couldn’t - magic took far too much focus and effort. Her bladder would leak the moment she even began to cast a spell of that nature, and she probably wouldn’t be able to finish it in the middle of an accident like that.

Sunscribe didn’t even try to hide the fact that she was writing down everything that Celestia had said; Luna wanted to fire a beam of magic at the scroll and disintegrate it on the spot, but of course, no magic.

“And the worst part is, you didn’t have your accident until right before we landed! I will commend you, you did a good job of holding it in that whole time prior to our landing, but it’s unfortunate that you lost it right before you would’ve been able to relieve yourself. Still, you handled it pretty well - you were surprisingly confident when you got off, even though there was still a yellow puddle in the chariot. I do envy your ability to be so bold, even after embarrassing yourself so much.”

“Sister…” Luna shivered hard; she was closer to another accident than ever before. At this point, she’d gone far beyond the amount of time she’d held her bladder in the chariot originally.

“Oh, I should probably let you know what we have next - it’s just one more short thing. I have one of my attendants coming in with some papers we need to sign, no big deal at all. It won’t take long.”

“I am very thankful to hear that,” Luna responded, though she wasn’t even sure if she could make it through that. She was still envisioning a yellow stain on the beautiful, fluffy, royal carpet before them, yellow pooling on the ground underneath her cushion, spraying from her slit uncontrollably, all over her hooves that were so desperately trying to block it in…

“Here they come,” Celestia said, as the door opened again. A grey pegasus with a black, slick, and modest mane entered, wearing a pair of sunglasses, her expression entirely neutral and blank. She held in her mouth a briefcase, which she set down on the ground, down the steps of the thrones. Her cutie mark was simply a paper that resembled a contract; clearly, she was the right pony for this very specific job. A guard followed in after her with a foldable wooden table on his back; soon, it was set up with a quill and a bottle of ink. The grey pegasus set out all of the papers, a total of seven in all, all needing signing from both princesses. “Well, that’s not too bad,” Celestia remarked, standing and beginning to walk towards the table like it was nothing. “Come on, Luna.”

Luna’s eyes went wide as she watched her sister easily descend the stairs. “Tia- I mean, Celestia, what is preventing you from simply using your magic to sign the forms from a distance? That was what I was intending on doing,” Luna said, concerned. Admittedly, she’d already decided she needed to avoid using her magic because of the focus it required, but walking down the stairs right then seemed far worse.

“It’s all part of the process with these forms - they’re very important, so we need to sign them physically, with our hooves.” Celestia easily picked up a quill in one hoof and began to sign each paper, only briefly skimming each one first. She’d already approved them all long ago. “Think of it as a little mini ceremony. Shadow Tail here can only take the contracts back once we’ve both signed them by hoof, no magic used, and we return to our thrones to signify that it’s complete.”

“This seems… entirely superfluous,” Luna said, slowly lifting her rear from the cushion; it was like looking down from a massive height. All her legs were asleep; immediately, that movement caused her to feel a leak coming, but she barely managed to stop it by quickly clamping her hind hooves together.

“It’s not so big of a deal. It’s good for us not to constantly rely on our magic.” Celestia set down the quill and looked back to her sister. “Are you doing alright?”

“Oh, um, yes, of course.” Luna took an extremely shaky step forward; her bladder panged and throbbed, and she had to immediately stop so she could prevent yet another leak. This was torture. “My, um, my legs simply fell asleep,” she said. Technically, that was true.

“Oh, I see. Well, take your time - there’s no need to rush.”

Actually, there really is, Luna thought to herself. She stepped forward again; this time, it was a little more stable, but now, she had to actually walk down the stairs. She gulped and continued onward, constantly rubbing her back thighs together, her bladder very, very visible from this angle, but she couldn’t do a thing to hide it. She felt lightheaded; these steps seemed so much more steep than usual. She kept making her way down, the movement further aggravating her bladder; at the same time, it gave her body the subconscious, entirely false hope that she was finally heading to a bathroom. She worried about the consequences of that accidental bit of self-deception.

Every pony in the room, Sunscribe, Celestia, and Shadow Tail, all stared at the slow princess. She could feel their eyes on her. Her cheeks turned red for what felt like the tenth time that day; there was nothing that could’ve humiliated her more. Filled with chagrin, she finally pushed herself in front of the forms, barely able to keep her balance on her shivering hooves, as she picked up a quill and began signing as quickly as she could. Her signature came out unsurprisingly shaky and poor, but still, she made it through, placing the quill back down. “Is that all, then?”

“As I mentioned earlier, we need to go back up the stairs to our thrones and sit down to complete the ceremony.” Celestia did as she’d said, yet again effortlessly sitting down. “Then, we’re done.”

Luna sighed; of course it wouldn’t be that easy. A part of her had been thinking that, at least if she had her accident there, while standing in front of Shadow Tail, her cushion would’ve been spared, but luck was not on her side. “Right…” she said, starting her shaky, slow ascent. Her bladder pounded worse than before as she brought herself further away from the bathroom, and eventually took her seat on the throne yet again - back to square one. If her body could be compared to an army of soldiers, then morale was as low as it could be. Even though she knew that she could go use the bathroom immediately after Shadow Tail left, it didn’t feel that way - she felt like, after all of this, it was never going to end.

However, contrary to her pessimistic outlook… Shadow Tail packed up the contracts, put them in her suitcase, nodded to the princesses, and she left. “Thank you, Shadow Tail!” Celestia called out; the door closed behind the contract pony.

“Wait, that’s it, isn’t it, sister? This is the end of our day’s work, yes?” Luna asked hopefully, yet again squirming and rubbing her crotch, her front hooves buried between her thighs.

“Oh, yes, that’s correct - we’re all done. Feel free to get some rest, sister, and perhaps relieve yourself - you’ve earned it~” Celestia winked, showing she’d known about Luna’s bursting bladder the entire time. Luna blushed embarrassedly at that realization, but she didn’t dwell on it for long - she could finally go to the bathroom now! All of those hours of sitting on the throne, gruelingly waiting to relieve herself, were now over. She looked to the bathroom; it was unoccupied.

Luna sighed in relief; she still struggled to believe it was really here. She felt like she’d just won a war. Slowly, she stood, happy to finally be able to relieve this great burden, to feel the sensation of her bladder emptying into the toilet; she was never going to let this happen again. She’d be making a rule of always using the bathroom before these meetings with her sister.

She raised her behind, lifted a hoof to step forward, still quivering… and suddenly, she felt something.

Something warm and wet… running down her hind legs.

Luna gasped; Celestia and Sunscribe both turned to watch as the nighttime princess began to wet herself, right there, standing over her throne cushion. At the most critical moment, Luna had let down her guard and allowed her bladder to overflow. She stood in sheer shock, frozen from embarrassment and chagrin, face red as a strawberry, as urine cascaded out of her slit, running down both of her hind legs; it soaked into her fur, making them darker, visibly dampening them and showing the trail of piss, leaving little to the imagination. It was so warm that it was practically steaming; it was almost like the sensation of a shower, but far less pleasant for obvious reasons.

Luna’s mouth hung open; her hind legs quivered lightly, urine continuing to spill forth, now coming out fast enough that it went as a full, strong, wide stream of golden yellow. It pitter-pattered onto the cushion that acted as Luna’s royal throne, hitting it right in the center and slowly soaking into it, dampening it, making the red a much darker color. Immediately, Luna remembered Celestia’s words about how she needed to not make a mess on these cushions and the carpet… and the peeing princess just whimpered, so shocked that she couldn’t stop the stream for even a moment, or move her body a single inch.

It just kept coming out, kept pouring forth; it soaked the cushion thoroughly, to the point where it began to bleed straight through or trickle off the top, the urine stream now making its way down to the carpet. It quickly cascaded in all directions, but particularly toward the steps, as that was where the platform naturally leaned; it made a river of yellow, going further and further, traveling fast, as the trickle straight from Luna’s slit hadn’t decreased its speed or strength even the slightest amount since it had begun. It stained the carpet horribly, only covering more and more of it as it came forth; eventually, it leaked over the front and, like a waterfall, began pouring down the steps, going further and further and further, traveling until it reached the bottom, and at that point, it just kept spreading further, bleeding into the soft carpet material.

Luna’s lips shivered; every attempt to make it stop was entirely futile. It kept coming; she could feel the little droplets bouncing off of the cushion behind her, hitting the back of her legs with their little wet warmth. It seemed endless; it had stretched on so long, she couldn’t even begin to estimate it. To her, it felt like hours were passing; her shame was immense, this was far worse than even the chariot ride. Eventually, however, it did stop, the last few drops dripping down, the stream ending, with the princess now standing in the puddle of her own yellow urine, the carpet and cushion soaked so much that it would take multiple days to fully clean.

Everypony was silent; Luna could barely bring herself to look at either of the others, but she forced herself to. Sunscribe’s face was entirely red; she’d clearly enjoyed that a lot, which was no surprise at all. As for Celestia… she just had a light pink blush, and a small smile on her face. She’d enjoyed it as well, though she was hiding it a bit better. “Oh, poor Luna…” she said, stepping towards Luna, the wet carpet squishing underneath her hooves (thankfully, part of her golden regalia were shoes for her hooves). She reached a hoof out and patted Luna’s head in a way that was both comforting and demeaning. “I should’ve realized you were struggling so much earlier - no wonder you looked so much like you did back on the chariot ride. Are you ok?”

Luna was practically speechless. “I-I…” She just stared at her mess; it was horrible.

“Don’t be too worried about the mess - we have maids for a reason. It’s going to take a lot of magic, sure, but we’ll have it cleaned up eventually… though, we might need a new cushion.” She put a hoof on the cushion and squished it; urine streamed from it, being squeezed onto the ground around it, like a rag being wrung out. “Why don’t you go get cleaned up and get some rest? I’ll let the maids know what happened, and I’ll make sure to be light on the details. Does that sound ok?”

“Tia, be honest…” Luna turned to her sister, her expression still one of mortified embarrassment. She could recognize that blush on her sister’s face, along with that mischievous smile. “Were you aware that I needed to relieve myself this whole time?”

Celestia shrugged. “Who’s to say one way or another? It’s a bit too late now, isn’t it~?” The princess chuckled; she wasn’t even bothering to hide it anymore. “Come on, I’ll help you get cleaned up~”

“Mmm…” Luna watched Celestia leave; she couldn’t believe this had happened to her. It was going to haunt her for years to come…

…but clearly, Celestia couldn’t be happier about it. Everything had gone perfectly; she couldn’t have possibly planned it better. She giggled to herself in amusement as she walked off.

And of course, Sunscribe had recorded every second of it… and had also enjoyed it immensely. It was rare for her to not be the submissive pony with the princesses, usually being the subject of whatever was going on, and she certainly didn’t mind getting to see it be one of them this time. She quickly left the throne room; she had a new story to enjoy.

—--------------------

The throne room was temporarily closed for cleaning for the next few days, though visitors were still accepted in the lobby that came before the throne room itself. The chagrin stayed with Luna for quite a while, though it wasn’t nearly as bad as it had been when the accident itself happened… however, Celestia couldn’t seem to stop teasing her over it, again and again, clearly milking it for all it was worth. Luna almost began to wonder if she should return the favor sometime.

While the two sisters were having breakfast, chatting as usual, Luna trying to avoid any discussion of the wetting-related events… a unicorn guard came through the door, floating a large, square-shaped box over to the sisters. “A delivery from Canvas Black.”

“Oh, how exciting! It’s our portrait!!” Celestia immediately went to open it; this surprise did help to cheer Luna up a tad bit, as she ran to Celestia’s side to take a look.

It was the original canvas and everything; a beautiful oil painting, depicting both of the sisters in all of their royal glory, with light touches of surrealism and plenty of color to make for a beautiful piece…

…except, Luna’s bladder bulge had been included, as well as the blush on her face, all in great detail and size. Her eyes widened; that very same blush came right back. Celestia giggled and looked at her sister. “It looks just like you, Luna.”

“I’m going to burn it,” Luna responded, curtly.

“I don’t think so~” The painting was grasped in golden magic, and it disappeared. Celestia had teleported it away. “There’s no way I’m letting such an adorable portrait of you go to waste~”

“Please tell me you do not plan to display it anywhere… public,” Luna pleaded.

“Don’t worry, dear sister - I know just the spot for it~”

That night, Celestia slept soundly, with the new portrait of her and her sister hanging on the wall, across from her bed. She’d be enjoying it for a very long time~
