Author's Notes:

The ponies put on some sparkly sports outfits Rarity designed and enter a volleyball tournament. However, Pinkie Pie ate too much cake before the game and destroys the only toilet in the area. To make matters worse, what they ate before the game didn't exactly agree with them. All of them are desperate to take a dump for the duration of the game. Will any of them make it? If not, who will last the longest?

Rainbow Dash and Applejack wanted to enter a volleyball tournament in which there were six players on a team, so naturally they asked Twilight Sparkle, Rarity, Pinkie Pie, and Fluttershy, all of whom agreed.

Rarity, being the fashion pony she was, decided that if she was going to play a sport, she'd do so in style, and fashioned sports outfits for each of them, consisting of sparkly skintight shorts and matching midriff tank tops which looked both sporty and lovely. Twilight's were dark blue, Rainbow Dash's were a medium shade of blue, Applejack's were red, Pinkie Pie's were dark pink, Fluttershy's were green, and Rarity's were purple.

On the day of the tournament, the ponies arrived at the arena and watched two of the other seven teams play each other.

In the middle of the game, Pinkie Pie made a sudden dash toward the only outhouse in the area (though there was another bathroom for spectators, which was out of the players' reach). Being Pinkie Pie, she had eaten about 50 cakes before the game and was now feeling its effects.

She entered the outhouse, closed its door, pulled her shorts down, and sat on the toilet.

Several farts could be heard outside by anyone who was close enough. Then there was the sound of a flush, and about 20 seconds later, Pinkie Pie walked out sheepishly, and walked over to a pony who worked at the arena.

"Excuse me, but I maybe kinda clogged up the toilet in the outhouse," said Pinkie. "You might wanna get someone to fix that. Also, there's no toilet paper in there." She blushed a little.

"I'll put someone on it," said the stallion Pinkie was talking to. "The right ponies should be here when this tournament is over." She put an Out of Order sign on the outhouse.

Pinkie bounced over to her friends and sat down next to them. "I hope none of you have to use the bathroom until the game's done, cause I just destroyed the only toilet here."

"Pinkie Pie!" said Rainbow Dash.

After this game was over, the Main 6 were up. They won their game easily, with Rainbow Dash and Applejack scoring most of the points, and then decided to have lunch while the other two teams played each other.

They got hay burgers, hay fries, sandwiches, and some cupcakes for dessert. They returned to the sidelines as the third game was almost over, and then the fourth game began.

As they waited for the semifinal round to begin, in which they would be playing first, all six ponies started to feel very uncomfortable. Something they had eaten just now didn't quite settle well with them. Perhaps it was bad hay in the hay fries or burgers, but they could feel their bowels getting full.

Pinkie Pie farted where she sat, and giggled.

"Pinkie Pie!" said Rarity, disgusted. "That wasn't very ladylike." Of course she was feeling gassy as well.

"Lighten up Rarity," said Rainbow Dash. "Every pony does it!" She unabashedly let a loud fart of her own, and laughed with Pinkie Pie.

"Ah don't think it's very funny," said Applejack, though she showed no shame in farting right after she said this.

Twilight farted loudly, and blushed, giggling nervously. Fluttershy and Rarity tried hard to hold it in.

"Just let it all out," said Applejack.

Fluttershy released a quiet, airy fart, and blushed, still feeling a little embarrassed about farting in front of all her friends.

Rarity held it in for as long as she could, until a loud wet fart forced its way out of her rump, causing her to blush profusely.

Pinkie Pie giggled and farted even louder. Fluttershy farted silently, still feeling embarrassed, but the smell of farts was already in the air and no one could tell.

PPPPPFFFFFFFRRRRRT!

Twilight let out a long, loud, wet fart, and giggled nervously again, her face still red from embarrassment.

"Nice one Twilight," said Rainbow Dash, farting just as loud, just as long, and almost as wet. "We should have a contest!"

"Really, no," said Rarity as she let out another wet fart.

"Yeah," said Applejack, farting again. "We need to save our competitive energy for the game!"

"Oh, I hope we don't fart in the middle of the game," said Twilight, now very nervous.

"Really?" said Pinkie. "Cause I think it would be the funniest thing EVER!" She farted as loud and hard as she could, but the fart turned very wet as she made a mess in her shorts. Pinkie's smile disappeared and her eyes went wide as she could feel more than gas come out of her rump. She blushed as the ponies could smell something worse than farts.

"Pinkie Pie, did you just... soil one of my outfits?" said Rarity.

Pinkie only giggled nervously.

"That food didn't just give us gas," said Twilight. "We need to get to a bathroom as soon as possible!"

"But there is no bathroom close by, thanks to Pinkie Pie," said Rainbow Dash.

"We're just gonna have to hold it," said Applejack.

Soon, it was time for the semifinal round. The Main 6 stepped up to play against one of the other three teams that made the semifinals. Ponies in the audience started laughing as soon as they saw the brown stain at the back of Pinkie Pie's shorts.

"Pinkie, be a darling and change out of that dirty outfit," said Rarity.

Pinkie ignored her, and the game began.

As the game progressed, all of the ponies except Pinkie Pie could feel the pressure in their bowels, and knew that it wasn't going to be all farts from now on.

Rainbow Dash let out a loud fart, and checked to make sure her shorts were still clean. They were. She was relieved at this, but still needed to take a dump really badly.

"Girls, I don't think..."

BBBBBLLLLLRRRRRTT!

Twilight blushed as her next fart released a wet brown mess into her skintight shorts. The audience started laughing again.

"Twilight!" said Rarity.

"I'm so sorry Rarity, I didn't mean to," said Twilight, who was ashamed beyond belief, and very uncomfortable at the mess she had made in her shorts, which smelled awful.

"Oh... it'll be fine, darling," said Rarity, who could tell how bad Twilight felt and didn't want her to feel worse. After all, she might end up in the same position if she didn't find relief soon.

Somehow they won, despite the state Pinkie and Twilight were in and how desperate the other four were. They sat on the sidelines to watch the other game. Twilight cringed at the squishy feeling under her rear, but Pinkie seemed to enjoy it. Both drank a lot of water.

"I'm gonna go behind that corner and do my business there," said Rainbow Dash. "Anyone else wanna try it?"

"What will you use for toilet paper?" said Rarity.

"I can do without it today," said Rainbow Dash.

"Ugh," said Rarity. "I won't do that then. That wouldn't be very clean."

"Hey, it might be even messier if you don't!" said Rainbow Dash, and she flew around the corner.

PFFFFFT

Rarity let out a wet fart, put her hoof on her rear, and sighed in relief. She didn't even care that she farted in front of all her friends - she didn't want to soil herself!

Fluttershy was feeling the pressure more than ever. She decided to let out another fart, hoping it would decrease the pressure and make her hold it...

PPPPBBBBTTTTTHHH!

She let out a squeak as she could feel her shorts filling up with manure rather noisily. She blushed beet red, feeling her mess squish beneath her tush.

"Don't feel ashamed, darling," said Rarity, who couldn't stand the smell but didn't want Fluttershy to feel bad. "You held it in as best you could."

Fluttershy started to feel a little better. "I... I think I should change out of this outfit."

She quietly made her way to a small pool of water just to the side, took off her sparkly, green, soiled shorts, threw them in a garbage can, and then took a bath in the water. She still smelled bad but was relatively clean as she sat down beside Rainbow Dash, who had also returned.

"Um... I just took a bath in a pool over there," said Fluttershy. "You two could do that too." She blushed lightly as she looked at Pinkie and Twilight.

"Nah, I'm fine," said Pinkie.

"I'd love to, but... that water must be pretty dirty now," said Twilight.

"Oh, I'm so sorry," said Fluttershy.

"That's all right darling," said Rarity, trying to hide her desperation, a short but wet fart making its way out of her rear. "I'd have done the same thing in your position."

Rainbow Dash's butt was very itchy since there had been no toilet paper for her to use, so she scratched a bit with her hooves. Worse, by the time the second semifinal game was over, Rainbow Dash had to go again!

Ten minutes went by before the next game.

Rarity was fidgeting harder than Applejack or Rainbow Dash, though Applejack needed to go almost as much as her.

"I have to go pee!" said Pinkie Pie.

"Me too," said Twilight. "And... that's not all I have to do."

Pinkie had eaten faster than the others, so she wasn't experiencing a second wave yet, but Twilight was, as she had eaten as much hay burgers as Rainbow Dash.

"Ahhhhhhh," said Pinkie Pie. Twilight looked over to see Pinkie's shorts darkening, and pee trickling off the bench she was sitting on.

"Ugh, why would you do that?" said Twilight. Rarity was just as disgusted but was too busy trying to hold it in to complain.

"Because I REALLY needed to go, and I knew I wasn't gonna make it," said Pinkie, who was still peeing.

"Uhhhh..." said Rarity as she let out a fart that was more boisterous and wet than before. "I can't... I can't hold it..."

PPPPPBBBBBBBLLLLLSSSSSH!

Rarity blushed beet red as she accidentally released the contents of her bowels into her shorts where she sat. She messed herself for about ten seconds, growing more embarrassed as she could feel her shorts get messier. This was the single most unladylike thing she could have done, especially since it had come with a very loud fart. She could feel her messy shorts squishing beneath her rear, and disliked the feeling at once, not to mention the smell. Although part of her felt a little aroused, she dismissed it.

Twilight moaned, as the sound of Rarity's noisy accident had reminded her of how much she needed to go, again.

And it made her lose control. Again.

Twilight farted loudly, releasing an even wetter, bigger mess into her shorts than last time, and the crotch of her shorts grew warm and wet as she began peeing as well. She blushed profusely, feeling more embarrassed than she ever had in her life. There was nothing she could think of that was less dignified, and she couldn't imagine how Rarity felt, being the most ladylike of the six ponies.

Twilight was still peeing when she farted again, and she was sure she might have added to the mess in her shorts. She moved her butt around, feeling the big mess she had made squish beneath her.

Rarity also farted three more times, soiling herself a little more on the third.

"I bet I can hold it longer than you, Applejack!" said Rainbow Dash.

"That ain't fair," said Applejack. "You just went after the last game."

"Well I ate twice as much as you and I have to go REAL bad! And I don't just have to take a dump, I have to pee too!"

"Then you're on," said Applejack. "Whoever soils herself first has to..."

BBBBLLLLLRRRRT!

"Dagnammit!" said Applejack as she could feel her shorts getting very messy.

"Ha! I win!" said Rainbow Dash.

"Ya had an unfair advantage," said Applejack as she finished soiling herself.

Eventually it was time for the final round to begin.

"Aren't you gonna change?" said Twilight to Rarity.

"I don't want to take a bath in that dirty water," said Rarity. "Even if I took these off, I'd still be... really dirty, and it would still show. Especially against my white coat."

The ponies walked to the court, feeling embarrassed as their soiled shorts were visible to all. Except Fluttershy, who wasn't wearing anything, and Rainbow Dash, although there was a small brown spot on the butt of her shorts already. They all smelled really bad (except Rainbow), and a mare who worked at the arena took a sniff of them as they walked by and cringed.

"You REALLY need to put more than one bathroom there," said Twilight, who, aside from Rarity, felt the most ashamed as she had soiled herself twice and peed in her shorts as well.

"I'll make sure it gets done," said the mare.

The Main 6 played against the last team. Twilight was so nervous appearing in front of a whole audience in her current state, that she peed again, and farted loudly. As they played, Rainbow Dash held it in as best she could. She had to pee and poop really badly, and she knew she wasn't going to make it. She hoped she could at least hold it for the entire game.

Despite how desperate she was, Rainbow Dash was still able to spike the ball a few times. Applejack and Pinkie Pie also did very good, despite the state they were in.

The game went on and on, with the score eventually tied so that whoever scored the next point would win. Rainbow hit the ball back against her opponent - Lightning Dust! Lightning Dust was wearing a teal shirt and white shorts, alone of her team, and Rainbow was pleased to see her shorts were stained brown at the butt and yellow at the crotch and legs. It seemed as though she and her friends weren't the only victims of the out-of-order outhouse.

After going back and forth for what felt like an hour, Rainbow Dash finally spiked the ball down, winning the game for her team.

Satisfied that she had won, Rainbow Dash let it all out in her shorts. She sighed in relief as her shorts grew wetter, messier, and smellier, rivers of pee flowing down her legs and very wet, foul-smelling manure noisily filling up her shorts, which became heavily stained at the back. Once she finished messing herself, she sat down, enjoying the squishy feeling while still peeing.

"You're... actually enjoying this, aren't you?" said Twilight, who could tell from the look on Rainbow Dash's face.

"I can't even imagine why anyone would like... that," said Rarity, who still felt very uncomfortable and humiliated in her own messy state.

"It's not so bad!" said Pinkie Pie. "Now that you think about it, it's actually pretty funny!"

"What will all of Ponyville think of us now?" said Twilight.

"We've saved Equestria too many times for this to bother them too much," said Rainbow Dash. "And you're a princess, you can tell them to keep this out of the papers."

"And never mention this again," said Rarity. "If they do, throw them in the dungeon!"

"I don't have a dungeon," said Twilight. "But I'll make sure they all keep it quiet just as soon as I get cleaned up." She was in the messiest state of all the ponies. She farted again, and giggled nervously.

The next day, there were five outhouses at the arena with bigger holes in the toilets, and the chef got some better hay and threw out all the bad stuff.

Within a week, all the ponies, even Twilight, Fluttershy, and Rarity, had put the whole messy incident behind them, and no pony ever mentioned it again, all the other ponies having forgotten it entirely. Except for a few ponies who had a fetish for it, who liked them even more because of it, though they were too polite to mention this to them.

Rarity also redid their outfits, as their old ones had been damaged beyond repair. She only had to do their shorts because their shirts had stayed clean and dry.

Unbeknownst to her, Rainbow Dash had kept her soiled shorts. She had been unable to get the stain or the smell out, but she didn't mind. Whenever she had a morning or afternoon to herself she'd use them to satisfy her new fetishes - scat and watersports!

Knownst to everyone else, so had Pinkie Pie. She was unashamed of admitting it, but never spoke of it again after mentioning it once, as she didn't want to remind the others of the event. Looking back at it, she and Rainbow found it rather fun, but they knew the others didn't want to think of it ever again.
