Chapters Rarity arrived at Canterlot High. She was wearing her usual purple skirt.
Her first order of business was to walk into the girls' bathroom. She didn't really have to go that badly, so she examined her hair and eye makeup in the mirror for a bit.
A closed stall behind her opened up, though there was no sound of a flush. Before Rarity could pay it much notice, she saw Aria Blaze's reflection in the mirror as she grabbed her from behind.
"Unhand me, you ruffian!" said Rarity as she squirmed in an attempt to get free of Aria.
"I've always wanted to do this to you, Rarity!" said Aria. "I've done this to a lot of girls, but you're the one I really wanted to get, and I'll make it extra special for you!"
She took Rarity into the stall she had come out of. The water in the toilet was yellow. Evidently, Aria had peed in the toilet and not flushed.
Rarity realized what Aria was about to do. "You wouldn't dare!" she said. "This is no way to treat a lady! That toilet is absolutely filthy!"
"Like I said, extra-special for you!"
Aria dunked Rarity's head in the toilet. Rarity's head was completely submerged under the yellow water. Rarity was disgusted, but kept her mouth shut to hold her breath. She did not want to get any of this dirty water in her mouth.
Then, Aria flushed the toilet. Rarity took a deep breath as soon as her head was no longer submerged, and Aria let go of her. Rarity stood up, panting. Her hair was soaking wet and smelled of pee.
"How dare you?" said Rarity. "It will take hours to get this smell out of my hair. This was the least dignified thing I have ever experienced."
"Except for that time you had a major gas attack," said Aria.
Rarity's face went bright red. "How did you know about that?"
"I have my ways."
Rarity slapped Aria in the face as hard as she could. Aria rubbed her cheek, and glared at Rarity.
"Bad girl. You should get a spanking for that."
Aria put the toilet seat down, grabbed Rarity, sat on the toilet, and put her over her knee. Rarity kicked and screamed, but Aria brought her hand down on Rarity's rear. Aria slapped Rarity's butt again, and again, and again, and Rarity whimpered with each swat.
After spanking Rarity 20 times, Aria grabbed some duct tape and tied Rarity's feet together.
"For heavens sake, what are you doing now?" said Rarity, who was too busy rubbing her sore butt to try to fight Aria off.
"Something I've been saving for one of you for a while!" said Aria as she began to tie Rarity's hands together.
Rarity elbowed Aria and slapped her in the face again. But with her feet tied together she lost her footing and fell on her butt. She whimpered as she felt intense pain in her rear. Aria picked up Rarity by her feet and hung her upside-down. Her skirt fell down and Aria could see her purple panties.
"Stop that at once!" said Rarity, who was blushing profusely with embarrassment.
Aria slapped Rarity's butt hard, and Rarity whimpered and stopped fighting back. Aria laid her facedown on the ground and tied her hands behind her back. Then she put the duct tape over her mouth, and sat her down on the toilet.
"Stay there until I come get you tomorrow morning," said Aria, and she positioned her butt in Rarity's face and let out a loud, wet fart that lasted seven seconds. She had been holding it in all morning after eating nothing but beans for breakfast. Only able to breathe through her nose, Rarity was forced to smell Aria's fart, and let out a muffled moan, for it smelled really bad. She struggled vigorously against her bonds, but it was no use. Aria had tied her tight.
Aria locked the stall door, climbed over it, and walked out of the bathroom.
Rarity sat there for hours and struggled against her bonds. She still had to go to the bathroom, and her desperation got worse as each hour went by.
Four hours later, the bell rang for lunch, and Rarity really needed to go. She let out several muffled groans under her duct tape gag, and tried to get free, but it was no use.
Then, she heard the door open, and someone entered the stall next to her. The sound of pee splashing in the toilet could be heard, and that made Rarity leak into her underwear for about three seconds. Afterward, she could hear a flush, and then the girl left.
Then more girls came in and the sound of running water could be heard as they turned the taps on. Rarity leaked more into her damp panties, soaking them. Rarity groaned through her gag, trying to get the other girls' attention and hoping they wouldn't notice that she had peed a little.
Eventually, the bell rang again for the afternoon class, and Rarity was left in her current position.
Her need to pee grew greater. Rarity struggled desperately against her bonds, and she could feel the pee sloshing around inside her. She knew she was about to burst.
After about half an hour, she couldn't hold it in anymore. Rarity felt her already-wet panties grow warmer and wetter, and a wet spot appeared on her skirt, rapidly expanding. Though no one could see this, Rarity blushed as she wet herself uncontrollably. After about five seconds the pee passed through her skirt and splashed into the toilet. The front and back of her skirt got wetter with each second, and her panties were absolutely soaked.
Rarity peed for about a minute, and then she finished, feeling ashamed that she peed in her dress.
She sat in her wet panties and dress for another hour, by which time it was half an hour until class was over. She did not want to be trapped here for the entire night until Aria came back tomorrow morning. So, she stood up and tried to open the lock with her head. She knew it would be humiliating to be seen in her current state, but there was a fountain nearby so if she could just hop over to it and take a bath in it, no one would know the difference.
However, before Rarity could even make any real progress on opening the door, she lost her balance and fell back onto the toilet. And then, her butt splashed into the toilet, as the seat was not down. She tried to get out but with her hands and feet tied she couldn't. It wasn't as though she was getting any wetter or dirtier - though the toilet was full of her pee, her butt was already soaked - but it was still very unpleasant and undignified.
Rarity stayed in this position until the bell rang for the end of school. Her heart sank. She'd be in this position for the rest of the night.
Then, Pinkie Pie suddenly climbed over the door of the stall. "Hey Rarity! Whatchya doin'?"
Rarity blushed at being seen in this state - she was very wet and smelled of urine, and her butt was still in the toilet - but she was still relieved to see her.
Pinkie got Rarity out of the toilet and untied her.
"How did you know?" said Rarity.
"Just a hunch," said Pinkie. "Now, let's go!"
"Can we wait until it's settled down out there? I REALLY don't want anyone else to see me like this."
"I've got it under control!" said Pinkie, and she opened the door, grabbed Rarity's hand, and ran fast, taking her along for the ride.
She ran into the gym, moving too fast for anyone to see the wet spots on Rarity's skirt. She threw Rarity into the showers and turned them on, and stood under the water with her.
"Now if anyone asks, I decided to randomly take a shower - which I sometimes do - and made you come with me!"
Rarity was extremely grateful. Now no one else would know that she wet herself, and Pinkie Pie wasn't even making fun of her for it.
...
The next morning, Aria walked into the bathroom. The stall she had locked Rarity in was closed, and she could hear the sound of several loud farts. Aria chuckled. Rarity must be messing herself very loudly!
Once the farting had subsided, Aria climbed over the door - only to find Pinkie Pie, wearing a cute pair of jean shorts.
"Pinkie Pie? Wha-"
Pinkie grabbed Aria from behind and held her head close to the toilet. It was full of diarrhea, and it smelled really bad. Aria frantically tried to wiggle free, but Pinkie dunked her head in the toilet mid-scream. After about ten seconds, Pinkie flushed, and pulled Aria's head out. Aria was coughing and sputtering, her hair soaking wet and very dirty.
"Next time you do that to Rarity, I do this to you!" said Pinkie. She sat on the toilet, put Aria over her knee, and spanked her 20 times. Pinkie could spank as hard as Aria, and her butt was in a lot of pain when it was over. At this point, Aria realized that she needed to pee very badly, for she was so excited to see the state Rarity was in that she had forgotten to take her morning pee.
Once Aria got to her feet, Pinkie stuck her butt in Aria's face.
PPPPPPPPPPPPPPPPPPFFFFFFFFFFFFFRRRRRRRRRRRRRRRT!
This fart was 16 seconds long and smelled so bad that Aria fell on her butt. Pain exploded through her rear, and she wet her purple jeans, blushing as a puddle grew under her.
"Oops... I might've farted a bit too hard," said Pinkie, feeling how wet and dirty the butt of her underwear was. "And I forgot to use toilet paper... Oh well!" She cheerfully walked out of the room.
Once Aria finished peeing, she stood up and ran home as fast as she could to change.
As she reached her front door, she felt a big fart coming and unabashedly let loose.
BBBBBBBBBBBBRRRRRRRRRRRRRRRRAAAAAAAAAAAAAP!
Aria's face went beet red as she made a big mess in her already-wet pants. The stench reached her nose and she nearly gagged.
She walked into the door, hoping to get to a bathroom and change unseen, but unfortunately for her, Sonata Dusk was just coming out of the bathroom.
"What's that smell?" said Sonata. She saw the state Aria was in, and giggled. "Heehee! Aria wet herself, and she soiled herself!"
"Shut up," said Aria, blushing profusely, and she took her change of clothes into the bathroom to clean up. She would never do anything like that to Rarity or any of the Rainbooms ever again!
From that day on, whenever Aria got nervous or scared, she'd wet her pants, and sometimes when she'd fart really loud, she'd mess herself.

Another request, and likely inferior to or repetitive of the first chapter.
Sunset's Swirlie
Sunset Shimmer was sitting at her desk, waiting impatiently for the class to end. She was wearing her short, gray shorts, and she was fidgeting, for she needed to pee very badly. Class was almost over, she could hold it until then.
Adagio Dazzle had challenged her to a soda drinking contest at lunch, which she had thrown to Sunset, and was hiding out in the bathroom ever since, waiting for Sunset to come.
While Sunset crossed her legs in the classroom, Adagio felt pressure in her bowels, and grinned evilly. She stepped into the stall, in which she had already peed into the toilet for just under a minute due to all the soda she had drank, and not flushed. She wanted this to be as bad for Sunset as possible.
Adagio pulled down her pants and sat on the toilet...
...
The bell rang. Sunset felt a little more relieved already. She immediately stood up and ran to the bathroom, both hands on her crotch.
As soon as she was in the bathroom, she ran toward a stall, but Adagio tripped her and she fell face first to the ground. Adagio picked her up and took her into the stall.
"What are you doing?" said Sunset. "I have to go!"
"I know," said Adagio.
Adagio positioned Sunset's head above the toilet, giving her a full view of the water. It was very yellow and had a lot of poop in it.
Sunset struggled to get free of Adagio, but Adagio forced her head into the dirty toilet. Sunset closed her eyes and held her breath, trying to avoid getting any of the toilet's contents into her mouth. This was so disgusting.
Her head had been submerged for five seconds when her shorts grew warm and wet. The experience had been too much for her.
She was still peeing when Adagio flushed the toilet. As soon as it started filling up with water again, Adagio released Sunset. Sunset was panting and coughing. Her hair was soaking wet and very dirty, and her shorts had a big wet spot. Her face was red with embarrassment.
Just then, Pinkie Pie came in, took one look at the scene, and hit Adagio over the head with a rubber chicken, knocking her to the ground. Pinkie hiked up her skirt and sat on the toilet, her feet on Adagio's back to keep her on the ground. Pinkie made sure Sunset could see her, and began peeing through her blue panties into the toilet, sighing of relief and giggling. She must have really needed to go, for she peed for just under two minutes.
Sunset felt a little less embarrassed at Pinkie Pie having seen her in this state, if she was willing to pee in her panties in front of her.
Then, Pinkie stood up, grabbed Adagio, dunked her head in the toilet, and flushed it. Once the swirlie was done, Adagio was coughing and spluttering, her hair soaked and smelling of pee.
"I knew I should have listened to Aria," said Adagio, and she ran off.
"She'll never do that to you again!" said Pinkie Pie cheerfully.
"Thanks," said Sunset, still a little embarrassed but feeling better.
"Come on, let's go hit the showers so no one can tell."
They made it to the showers without anyone seeing the state of Sunset's hair or shorts, and Pinkie turned on the showers. Sunset thoroughly enjoyed it, washing all the pee off her, and the traces of poop out of her hair.
"Isn't anyone gonna wonder why we're soaking wet?" said Sunset.
"I'll just say I took a random shower and convinced you to go with me," said Pinkie.
No one would believe for a second that she wouldn't , though Sunset.
...
Adagio returned to their house.
"Heehee, what happened to your hair?" said Sonata Dusk. She sniffed. "You smell kinda funny..."
"Quiet," said Adagio.
"So, you tried to give them a swirlie," said Aria Blaze.
"I did, until Pinkie Pie ruined everything!"
"I told you that would happen."
"There's a snake crawling through your pigtail."
Aria screamed with fright and wet her pants. She checked her pigtail for a snake while Sonata laughed.
"That wasn't funny!" Aria headed to her room to change, while Adagio felt a little better now she'd taken out her frustration and humiliation on someone.
Author's Note
Another chapter by request, to complete a "trilogy"
Pinkie Pie's Swirlie?
Adagio Dazzle got out of the shower, her hair now perfectly clean.
"About time," said Aria Blaze, who, although now wearing one of her alternate outfits, hadn't washed yet.
"How hard can it be to give someone a swirlie?" said Sonata Dusk. "I bet I can do it better than you!"
"Go ahead," said Aria.
"Pinkie Pie's the one you want to go for," said Adagio.
"I'm not sure who to root for," said Aria. "Whoever wins, I win!"
...
"Hey Pinkie Pie, wanna do a soda-drinking contest?" said Sonata as she walked up to Pinkie Pie at the entrance to Canterlot High.
"Sounds like fun!" said Pinkie, who was wearing her jean shorts today.
Sonata took out ten bottles of soda, five for each of them. "Whoever drinks them all first, wins! And whoever has to stop first, with the most soda left, loses!"
They each took their first bottles of soda.
"Ready... start!" said Sonata.
In just over a minute, Pinkie finished chugging the fifth bottle, while Sonata was still on her fourth.
"Congratulations! You win!" said Sonata. "I'll finish these anyway." She finished drinking the fourth bottle, and drank the fifth, a little slower.
"That was fun!" said Pinkie. "We should do it again sometime!"
"I'm sure we will!" said Sonata.
...
Pinkie's first class went without much trouble. At the start of her second class, however, she immediately felt she needed to go to the bathroom very badly.
She raised her hand. "Excuse me, I REALLY have to go to the bathroom!"
The teacher said she could, and she zipped out the door.
...
Sonata waited impatiently for Pinkie Pie. How much longer until the silly girl needed to go to the bathroom? Already she had to pee badly!
She didn't want to go into a stall and pee because she might miss Pinkie Pie. However, there was no sign of her now, so she decided she'd do it. How long could it take?
She ran into a stall and started peeing, sighing of relief. After five seconds she suddenly heard the door open. Sonata stood up and pulled up her pink panties, though she didn't stop peeing for three seconds after, wetting her panties a bit. Sonata blushed lightly, but for the moment her priority was giving Pinkie this swirlie!
She rushed out of her stall and tackled Pinkie, knocking her to the ground. She picked her up, leaking a bit from the effort, and ran into a stall. She realized this was not the toilet she had peed in, because the water was completely clear. So, she took Pinkie into the next stall, with great effort, as Pinkie was frantically wiggling against her, dampening her jean shorts slightly.
Sonata submerged Pinkie's head under the yellow toilet water, but Pinkie elbowed her in the stomach, causing her to pee for another five seconds. Sonata let out a whimper and released Pinkie, putting her hands on her crotch as a wet spot appeared on her pink skirt, and pee trickled down her legs.
Pinkie jumped behind Sonata, grabbed her, and forced her head into the toilet. Pinkie climbed on Sonata so that her back was between her legs. With a sigh of relief, Pinkie let go and began peeing herself, soaking Sonata within seconds. From a combination of her head being underwater and Pinkie peeing on her, Sonata also began peeing full force, soaking her skirt further. Her panties were absolutely saturated within seconds.
After about half a minute, Pinkie suddenly remembered, and flushed the toilet. Sonata took a deep breath once the toilet was empty, but Pinkie remained where she was, still shamelessly flooding her jean shorts and drenching Sonata further.
After about two minutes, Pinkie stopped peeing. Her shorts were completely soaked, but she didn't mind. Sonata, on the other hand, did mind the state she was in, even though she finished peeing about twenty seconds before Pinkie.
Pinkie released Sonata, and they sat in the big puddle they had made in the middle of the stall.
"Well, I messed that up," said Sonata.
"It's all right," said Pinkie. "Adagio and Aria messed it up too."
"Maybe we could try to give each other swirlies again!"
"I'll always be ready for you!"
"Heehee... you really needed to go, didn't you?"
"I think about half of this puddle is yours!"
"Yeah, I really couldn't hold it!"
Pinkie and Sonata giggled for a bit, as if they forgot they were supposed to be enemies, then Sonata got up and ran out the door.
Pinkie returned to her classroom. "I didn't make it," she said casually.
The other students were amused at the state Pinkie was in, and some chuckled, but they didn't ridicule her. They just dismissed it as her being Pinkie Pie!
...
"I knew you'd fail," said Aria at the sight of Sonata, who was soaked with piss from head to toe.
"At least I didn't mess myself!" said Sonata.
Aria slapped Sonata in the face. Sonata ignored this and proceeded to tell Adagio and Aria what had happened.
"So, are we through with trying to give the Rainbooms swirlies?" said Adagio.
"I can't wait to go after her again!" said Sonata. "It'll be really fun!"
Aria facepalmed. If her idea of a fun time is getting a swirlie, wetting herself, and being peed on, that's fine by me. It'll be fun watching her get her ass handed to her over and over again.
