You know, Sunset had thought she was being really polite. Obscenely polite. This cursed place was no Canterlot Palace (despite sharing the dubious moniker), and it was barely a passable educational institution. So really, the incident really shouldn't have garnered any sort of remote attention.

And yet here she was anyway, sat in the office of Principal Celestia, facing whatever punishment the lady sought to give her. Her arms were crossed petulantly, and her foot tapped against the floor in a rapid rhythm as she waited. This really was absurd. How the hell was she in trouble for this? She had, admittedly, done many horrible things in her brief time in this world, and yet, had not once found herself in reception of any sort of disciplinary action. But now, that streak would be broken.

All because she took a dump in the hallway.

Jeez, these hoo-mans were horribly uptight. It was only the second week that she was here, and she had been trying hard to get the hang of how things worked around here. Really, she had been! She had even gone out of her way to not do it in a well-traveled part of the school!

Sunset had pissed in the library a few times, but no one had ragged her on that so she just kept doing it. But she had, up until that point, limited her defecation to her own, humble abode. Sure, her apartment constantly smelled of stale scat and drying piss, but the girl had quickly become noseblind to the odors after a short while. And besides, having a few lumps of her own manure lying around often helped out when she was feeling horny but couldn't quite bring herself to the edge like she needed to.

On the afternoon in question, she had really needed to take a shit and the library was on the complete opposite end of the school. She also doubted she could make it back to her apartment, and unlike the hedonistic ponies of Appleloosa, she didn't feel too keen on dropping a thick deuce in public. So, she found a familiar, quiet hallway and went to do her business.

The teen walked briskly to the end of the empty corridor and quickly took a squat. She fluffed her short skirt out of the way, so as to not make a mess of them, and relaxed. She wasn't wearing any underwear of course, because at the time, she had not yet learned it was an essential part of the human wardrobe.

Sunset let out a sigh and closed her eyes as her bladder released first. A deep, yellow arc of piss spewed out of her pussy, splattering onto the tiled floor of the school hallway. The noise echoed in the derelict space as a warm puddle quickly began to grow underneath the girl. She shifted her feet backwards to avoid soiling her shoes as she continued to relieve herself onto the floor.

As she continued pissing, the blockage at her backdoor began to move. A loud, dry fart escaped first - a mere precursor as to the mess that was to come. Her anus flattened outwards under the pressure before it began to open up around the head of a firm, dark brown log. The thick turd pushed its way out steadily, dropping to the floor and coiling into a neat, smelly pile before it broke off after a few more inches. That was not all, though, as the head of another log quickly began to slither out next.

Sunset lost herself in the rhythmic crackling of her bowel movement as more firm, brown logs slid out of her anus and joined the growing pile of waste on the floor. She had produced quite the mound of scat beneath her, having pinched out almost seven whole, firm logs of a similar shade of brown. Damn, she really needed to get one of those cool phonecell things so that she could take a picture of the next impressive load she produced.

Her urine stream by now had gradually taped off, with only a few small drops of warm urine still leaking out of her wet pussy. She reached down with a hand to rub at her cunt to wipe away any residual piss before she brought it up to her mouth and dutifully licked her digits clean. The salty taste of her pee was faint, and it barely took any time for her to clean her fingers completely of her tangy brew. However, the taste of her urine stirred something inside her crotch.

Sunset reached down and began to idly play with her wet snatch as she pooped, cooing delightfully at the pleasurable jolts her ministrations sent down her spine. As she was, of course, naturally a pony, relieving oneself was already a deeply pleasing experience that often led to various sexually-charged escapades. She was no stranger to masturbating whilst pooping or shortly there afterward. It was all part of the pony experience.

It was during this debaucherous detour that she was, unfortunately, interrupted. She had only just begun to finger herself when a startled voice forced her to remove her fingers from her dripping cunt and turn to see what all the ruckus was about.

"S-sunset!?" a timid voice called out, and Sunset looked down the hall to see Fluttershy standing at the corner of the other corridor. She carried her school books in her arms, and her eyes were wide in shock.

Oh yeah, that's why this hallway looked so familiar, Sunset thought to herself. This was where Fluttershy's locker was. Sunset was, of course, also a bitch, so she decided to use this encounter to her advantage. She had a certain image to uphold, after all.

"Hey, Fluttershy," Sunset replied, her voice dripping with false cheer. She grinned at the girl as she shyly peeked out from under her pink hair. "Sorry, just thought that this would be the perfect place to... unnnh" - her jab was interrupted by a boisterous fart and the start of yet another thick turd sliding out of her ass - "drop a nice, fragrant load!" The crackling of her shit filled the momentary silence as she closed her eyes in the bliss of her shitty release. "I just knew you'd love this deposit!"

"Sunset... what...?" Fluttershy began, but then the foul fumes of Sunset's scat hit her nose, and she quickly turned tail and ran in the opposite direction. Oh dear, it seemed as though she had broken the poor girl. Oh well, Sunset would have time to bully her later. Right now, she was busy finishing up some of her own 'personal business.'

Said 'personal business' involved squeezing one last, firm turd out of her gaping butthole and punctuating it with a nice, warm fart. The stench at her end of the corridor was pungent and stunk of fresh piss and earthy poop. Sunset breathed it in, enjoying the odor of her own brew, and flexed her stained pucker a few times to make sure all of her waste was out. She could feel the warmth of her shit steaming up against her bare ass beneath her skirt, and she took a few seconds to cherish just how pleasant the feeling was.

But, a girl has other things to do.

So, Sunset reached under her ass with her hand once again and wiped at her shitty anus a few times to scrape all of the fecal residue onto her fingers. In Equestria, she normally wouldn't make such an effort at unnecessary hygiene, but for some reason, in her human form, leaving poop to dry and cake on her sensitive butthole was very uncomfortable.

Satisfied that she had scrubbed enough of her crap off of her pucker, Sunset brought her hand up to her face and gave it a few sniffs before sticking the shit-caked fingers into her mouth to clean them off. No sooner than the bitter-tasting grimy texture of her poop hit her tongue than she was startled for the second time that afternoon.

"Sunset Shimmer!" her voice was called out again, this time a bit more forceful and a bit more (unfortunately) familiar. Sunset's head shot upwards, dirty fingers still in her mouth, to see none other than Principal Celestia glowering at her from the end of the hallway with Fluttershy's timid form cowering behind her.

"Uh, hi," Sunset said as she sucked the last of her feces off of her fingers and awkwardly waved at the two down the hallway. "You've come at a bit of an awkward time."

So, yeah. After being forced to clean up her mess, Sunset was now seated in Principal Celestia's office, waiting for the inevitable lecture that was about to come.

"Sunset, what... why..." Celestia stuttered, having not quite found the words she needed. She pinched her brow between her fingers as if she were in great pain, and tried again. "Sunset..." she said. "What on Earth compelled you to defecate in the school hallway?"

"I needed to poop," replied Sunset plainly. "And I was closer to that hallway than the library."

Celestia's eyes widened. "The library?" she echoed, completely lost for words. The library? What the hell did this girl do in the library?

"Yeah, and I figured it would be more polite to do it out of sight, and there was no one in that hallway, so..." Sunset gestured with her hands. "I dropped my load there." Usually, she’d throw more bite into her tone when speaking to anyone with authority in this godforsaken place, but she was still just trying to figure out exactly why she was in trouble. "Is this because I teased Fluttershy about it?"

"What? No... well, partially yes, but... wait, you teased Fluttershy about it?" Celestia stammered, still at a loss for exactly how to approach whatever the fuck this was. So she stopped trying to figure out how to approach it and instead just blatantly said, "Sunset, you took a shit in a hallway and are acting like we're the ones being weird about it."

Sunset threw her hands up in exasperation. "You are the ones being weird about it!" she yelled. "Where the fuck was I supposed to go poop?!"

"In the fucking bathroom, like a normal person?!" Celestia shouted back, finally asking the question that any normal, sane human being would be wondering at that moment.

But Sunset just stared at her blankly. "What the fuck is a 'bathroom?'"

Celestia slammed her head down onto her desk in defeat.

I'd like to visit Sunset's apartment, if you know what I mean...
