Pregnancy is a bitch. It is encumbering, uncomfortable, and it gives her the fucking runs like there is no tomorrow. (And don't even get her started on the morning sickness). Cadence liked to think that she was a reasonable mare. She was polite, and cared deeply about her subjects and fellow rulers. But there was nopony she would not kill to push this devil child out of her right this very second.

Okay, maybe she was overreacting - the hormones were definitely getting to her. It was not all bad. She did thoroughly enjoy moments like this, where she was lying back on her couch, hooves placed against her belly, and feeling the foal press up against her. Cadence intimately knew the definition behind "little bundle of joy" in these moments, and a wide smile was spread across her face. One of her hooves wandered down to her swollen teats, pressing against them lightly and trying to relieve some of the stress that she had been feeling in that area for a few weeks now. Her foal gave one last kick, and Cadence smiled, rolling off of the couch and standing up. She needed to get ready for tonight, and her mood briefly soured at the thought.

It was times like the one tonight that really pushed her to her limits. Political balls to meet with all of the ambassadors and dignitaries and essentially check in on all of the nations that Equestria decided to connect with. It was embarrassing and Cadence hated the way that everypony looked at her and her swollen belly. She loathed the questions about how far along she was, and did she know if it was a colt or filly.

Tiara in place, Cadence left her bedroom and made her way down towards the main ballroom of the Crystal Palace. Maids and Royal Guards nodded and bowed as she went, and she gave them reserved smiles in response. The entire palace staff knew that she had been curt and on edge for the last ten months, and as she approached the final stretch of her pregnancy, it was not getting much better. So everypony knew to just smile and stay out of her way. Another reason to want this pregnancy to be over, she missed interacting with the subjects in a more pleasant manner.

She approached the ballroom, walking up to the doors and nodding at the guests still waiting outside. Two royal guardsponies bowed and opened the wide, crystal doors to the large room, and Cadence took a deep breath before stepping through. The ballroom was full of a couple hundred ponies, and Cadence internally groaned at the realization that she would be required to speak to most of them. She spotted Shining Armor across the room, and she shared a weak smile before taking a deep breath and heading over to the first group of ponies.

Conversation after conversation was shared, and Cadence did her best to pay attention and keep up. A nagging presence in her lower stomach was slowly growing, but Cadence pushed the discomfort back. She was already hauling around a plump, over-full belly, what was a little more discomfort? She knew she would eventually need to take care of it though, her pregnancy did not take kindly to her trying to hold her shit in.

The conversations were exceptionally dull, and the pressure in her rear was getting worse. Cadence just wanted to get this over with and go take a quick dump before pigging out at the buffet and calling it a night. Unfortunately, it would be unbecoming of her to just shit in the middle of the room, and it was expected that she would excuse herself to someplace more private to do so. It was ridiculous in her opinion, most ponies just pooped out whenever, wherever. But this was a "formal" event, and thus a relief area was set up in some corner of the room for the common ponies, and a more private room was readied for any royalty that might need to relieve themselves. Archaic traditions like this were not necessary in Cadence's opinion, and she knew that Celestia shared her views. If anything, Celestia would probably be overjoyed to watch ponies shit and piss everywhere.

Things took a turn for the worse, however, when Cadence was speaking with a noble unicorn from Canterlot. The stallion was talking about some trivial details regarding his finances and some taxes on them that he felt was unjust. The issue was not under Cadence's purview, and she couldn't care less, however she nodded along politely with each sentence. The unicorn had probably already talked Celestia's ear off, and Cadence supposed it was just her turn to take the brunt of it.

"It is incredible, you know," he was saying in a pompous voice that betrayed just how much he was full of himself. "Just how much the Diarchy sees fit to steal from hard working, wealthy ponies like me." Cadence fought to not roll her eyes. "It is just simply a load of horseapples in my opinion, don't you agree?"

A wet, drawn-out fart decided to choose that moment to sneak its way out of her puckered asshole. 'Well, way to say exactly what you were thinking, Cadence,' she thought to herself. A deep blush flashed across her face as the noise caused the conversation to stop midway, and she quickly excused herself and walked away. In a matter of mere moments, the pressure in her colon had increased drastically. Cadence was very suddenly keenly aware of the presence of messy, muddy shit pressing up against her strained anus, desperate to push its way out of her ass. She clenched her butthole as tight as she could, pleading with her ass to not explode out on the ground in the middle of the ballroom.

Cadence scanned the room, eyes locking onto the corner that the castle staff had set up out of the way. A few ponies were there relieving themselves, and she watched as logs slid out of their anus and urine splashed onto the floor. She urgently began to make her way over, trying not to act to desperate, and also fearing that any sudden movement would cause her to lose control. The alicorn ducked and weaved between ponies, and suddenly her face paled as she heard somepony call out her name.

"Oh, Cadence!" Princess Celestia called, coming up to her. A male hippogriff was next to her, undoubtedly some foreign dignitary who was invited to this ball. "Allow me to introduce you to Golden Sea. He is an ambassador from-"

Celestia droned on and on and Cadence got more and more desperate. It took all of her willpower to not shift her hooves at her discomfort and to keep her pucker clenched as tightly shut as she could. However she would not last much longer. She nodded and "mhm'd" and smiled through gritted teeth as her aunt went on about the status of Equestria's relations with the hippogriffs and how their two economies were highly beneficial to each other. Cadence absorbed a miniscule fraction of what Celestia was saying, too focused on not shitting herself to pay any actual attention.

Her clenched posture was weakened however, and a squeaky fart alerted her to that fact. No other pony seemed to have heard it over Celestia's incessant rambling, but alarm bells started ringing off in Cadence's head. That tiny fart was the beginning of the end for her and she started panicking.

"E-excuse me I g-gotta go," she muttered desperately trying to extract herself from the conversation. But Celestia paid no attention and kept speaking anyways. Cadence's butthole quivered again, this time letting a wet, rancid fart burst forth, tiny flecks of pony poop accompanying it. The loud, brappling noise interrupted Celestia, and she finally stopped speaking to look down at Cadence with wide eyes. That last fart signalled the beginning of the end for Cadence, and with a pained moan she lifted her tail, knowing that further restraint would be futile. With another loud, wet fart, the dam finally burst.

Cadence's once-pink anus opened up to allow a massive torrent of muddly, almost entirely liquid poop flow forth. It fell from her ass in wet bursts, splattering against the marble floor with loud splashes. Her anus burned with the heat of her shit, the Cadence did all she could to hold bath from moaning, instead panting from the sheer relief she was feeling. A few chunks of semi solid turds joined the ruckus, briefly plugging up her rectum and flying out of her anus with force, landing an incredible distance away. Wet, sloppy farts echoed in the sudden silence of the chamber, joined only by the constant, wet splattering of her diarrhea as the princess of the Crystal Empire shat herself in the middle of the ballroom.

Suddenly finding that she couldn't hold it back anymore, a long moan of relief rose out of Cadence's throat. Her eyes were practically rolling as her tongue lolled out, overcome with the unique pleasure of relief. The fact that hundreds of ponies were watching as she was spraying her shit onto the floor took a backseat to the insurmountable relief she was feeling in that moment.

A somewhat solid horseapple suddenly pressed up against her rear, temporarily blocking the flow of liquid crap. Cadence straigned, her dirty, shit-stained anus flattening outwards as she tried to push it out. Her pucker slowly spread around the lip of the log, the turd inching its way out at a miniscule pace. Cadence paused to take a breath before continuing her efforts. The thick poop finally made some significant progress, sliding out a bit more and hanging down from her ass. With a final push, it finally slipped all the way out, falling in the center of Cadence's muddy puddle with a dull splat. A pitiful bubble of liquid shit followed, plopping out with squlching farts.

Her bowels emptied, and not able to hold anything back anymore, Cadence's pussy lips parted and a stream of golden piss sprayed out, splattering on the ground between her rear hooves. Cadence let out a sigh as she peed, and finally looked up to see the scene around her.

Celestia's eyes were wide, and her cheeks were flushed a deep red. Cadence noted with curiosity that her wings were stiff, pointing straight up towards the ceiling. Next to her, Golden Sea was equally shocked and aroused, his turgid member flexing beneath his stomach. Other ponies around her had similar looks of surprise and horniness, and every single pair of eyes in the room were on her.

She suddenly realized that she had been pissing for quite some time, and blinked in surprise. A feeling of trepidation came over her as she realized that she wasn't actually peeing anymore. Her eyes darted around the room, searching for her husband, and panicking slightly when she finally locked onto his gaze. He too, was showing clear signs of arousal, his thick cock throbbing under his body, and hefty balls hanging low. She could not think about that now though.

"S-shiny," Cadence said softly, her voice wavering.

Her husband stepped closer to her, doing his best to avoid the mess she had made. "Yeah, honey? What is it?"

Cadence looked at him, shaking slightly and her pupils shrunk to pinpricks. "I think my w-water just broke."

Shining Armor fainted, falling face first into the puddle of his wife's mucky diarrhea.
