Author's Notes:

This chapter contains fart scenes. Not recommended if that's a huge turn-off for some omorashi lovers.

I considered making this part of the other Twilight's Desperation story, but its style is too close to the other chapters in this story for me to put it under any other.

Twilight Sparkle was with Princess Celestia in Canterlot, getting ready for a series of volleyball games the princesses would be playing all around Equestria. By drawing for teams, it was determined that Twilight would be on Celestia's team against Luna and Cadence.

Celestia slipped a yellow tank top and pink shorts on Twilight. The pink shorts felt extremely tight; tighter than anything she had ever worn.

"Is this really necessary?" said Twilight.

"It's traditional," said Celestia as she put on a similar yellow tank top.

"These are really tight."

"My sister and Cadence and I like them tight, and I think you will too," said Celestia with a wink, slapping Twilight's butt playfully before snapping on her own skintight pink shorts.

Twilight had to admit, she did kind of enjoy the feeling.

"How do I look?" said Celestia, turning around so her rear was facing Twilight, and rubbing her tush almost seductively with her hoof.

"You look great," said Twilight. She turned around and raised her behind in the air. "How do I look?" She slapped her own tush a little too enthusiastically.

"Ready to play. And your butt looks really cute in those shorts."

Twilight blushed and giggled a bit.

It wasn't as though Celestia and Twilight were sexually attracted to each other; this was something that mares sometimes liked to do when wearing skintight pants, shorts, or jumpsuits.

They met up with Luna and Cadence, who were wearing dark purple tank tops and equally tight black shorts.

Naturally, their first game was in Canterlot. The princesses had a lot of fun, but as it was a very hot summer day, they were exhausted by the time it was over (Twilight and Celestia won), so they drank a lot of water before flying to Ponyville for their next game.

As soon as they touched down, Twilight farted loudly, and blushed.

Celestia giggled, and Twilight felt less ashamed knowing Celestia wasn't offended. She farted again, a little more confidently since Celestia found it funny.

Feeling hot and thirsty from the flight, the princesses drank more water. Twilight drank twice as much water as the other princesses, and they made their way to the volleyball court.

As the game was about to begin, Twilight farted again.

PPPPPPFFFFFFFFTT

The audience laughed, and Twilight blushed a little more. She wished she hadn't eaten so many beans earlier today. But she loved beans so much, even if they made her really gassy.

As their volleyball game progressed, Twilight felt a need to pee. The water she drank was going through her. But, she didn't let it affect her performance, and she and Celestia won again.

"Is there enough time to go to the bathroom?" said Twilight.

"Not before we fly to Appleoosa," said Celestia.

Twilight accidentally farted again out of nervousness, and she and the other princesses drank more water and took off for their next game in Appleoosa.

They had farther to fly than from Canterlot to Ponyville, so the princesses each drank two glasses of water. Except Twilight, who drank four.

Twilight had a harder time playing the next match, because she really needed to go. She farted a few times during the match, to the amusement of the audience, but she was more focused on the game and the throbbing of her bladder. Luna's team won this time.

The princesses' outfits were damp with sweat now. They drank more water, Twilight again drinking twice as much despite her need to pee. The other princesses stared at her, knowing she was about to have a very uncomfortable day.

FFFFFFFFFRRRRRRRRRRRRT!

Twilight let out a very loud, wet fart after she finished her last glass of water. She hardly felt embarrassed, for she was used to farting a lot by now and the other princesses didn't mind.

Their next game was in Baltimare, which was an even longer flight. Twilight crossed her legs. She had to pee very badly, and her skintight shorts weren't making it any better.

The other princesses were now starting to feel the need to pee as well.

After arriving in Baltimare and drinking more water, the princesses went to the court and played their game. It was a little difficult for all of them, particularly Twilight, who was in desperate need of a bathroom, and was still very gassy. Luna and Cadence won this game.

"I think we should use the bathroom now," said Celestia.

Twilight nodded her head frantically, now dripping with sweat from both playing in the summer heat and her desperate need to pee.

"We have no time," said Luna. "Our game in Fillydelphia begins in five minutes."

Twilight groaned, and, despite knowing it would increase her need to pee, drank five bottles of water, while the other princesses only drank one each.

They flew to Fillydelphia, which, thankfully, was close, and played their next game. Twilight could barely even hit the ball anymore, she had to pee so badly! The other princesses were starting to get more uncomfortable too, but still played well. Luna and Cadence won again.

The princesses were dripping with sweat now.

"I REALLY need to go!" said Twilight, doing the pee pee dance frantically and letting out a few wet farts. "Can I stop for a minute?"

"It would be a good idea," said Celestia.

"Except, we'll be late for our next game," said Cadence.

Feeling very uncomfortable, but drinking lots of water despite that, the princesses flew to their next game in Manehattan. Twilight let out a boisterous fart along the way. It was only slightly longer than the flight from Canterlot to Ponyville, but it felt like hours to Twilight.

Luna realized that her shorts were already soaked, so if she wet herself now, no one would know the difference. With all the water she drank her pee would be clear and odorless. So, she slowed down a bit so that she was behind all the other ponies, not caring that she sometimes got a whiff of Twilight's flatulence, and let it all out in her shorts, sighing of relief.

Cadence heard this, and decided to go down the same path, peeing in her already-wet shorts.

The idea did not occur to Twilight and Celestia, who were flying ahead of Cadence, who had kept her relieved sigh to herself.

As they played their game in Manehattan, Luna and Cadence played better than before, and Twilight and Celestia couldn't understand why, since they'd been desperate to pee not too long ago. Twilight leaked a bit into her shorts, and Luna and Cadence won by a landslide.

The very sweaty princesses drank more water, Twilight again drinking a lot, and then flew to their next game - in Cloudsdale, which was their farthest flight today.

"Couldn't we take the train?" said Twilight, with both hands between her legs, farting loud and wet again. "To Ponyville at least?" she added, remembering their destination was somewhere that trains do not go.

"We fly faster than the train," said Celestia. "I calculated how long it would take, but I didn't factor in bathroom breaks..."

"I'll see you there!" Twilight flew toward Cloudsdale as fast as she could, hoping to get to the bathroom first. She farted a few more times along the way.

She reached Cloudsdale about three minutes before the game was about to begin. She entered the bathroom closest to the volleyball court, but the stalls were all taken. She frantically did the pee dance for two minutes, feeling immense waves of pee sloshing around inside her, and then realized the game was about to begin, so she ran to the court, dribbling the whole way.

The game began, and Twilight leaked every time she hit the ball, and even a few of the times she farted. She turned away on one leak, and Luna accidentally spiked the ball hard into her butt. Twilight leaked for five seconds at this, but held it in and continued to play.

Celestia also needed to pee badly, though not as badly as Twilight. Noticing Twilight seemed really desperate, Luna and Cadence hit the ball to Celestia more than her.

Nevertheless, Twilight eventually reached her limit. She let out a whimper as she lost control and peed full force, soaking her already-wet shorts. Her pee didn't smell; it was diluted due to all the water she drank, but it gushed down her back legs in torrents. The puddle was hard to see because it was on clouds, but pegasi in the audience noticed Twilight peeing and began to laugh.

Twilight blushed and giggled nervously, still peeing.

"Don't feel bad, Twilight," said Celestia as she was about to serve, patting Twilight's butt lightly. Twilight relaxed, for she liked it when ponies did this. "You held it as long as you could, and there's no way I could have held it after drinking that much water. In fact, I'm not sure how much longer I can hold it, and I didn't even drink half as much as you!"

Crossing her legs, Celestia served the ball to Luna, who hit it between Celestia and Twilight.

With a loud, wet fart, Twilight flew forward and hit the ball over the net, still peeing but feeling less ashamed. She peed for a little over two minutes, and the audience cheered for Twilight before she was done peeing due to her performance while in the middle of wetting herself.

Luna and Cadence still won, but it was close.

They flew to their next game in Los Pegasus, which was as long a flight as the flight to Cloudsdale. Celestia was now desperate to pee, and held it as long as she could.

Luna and Cadence giggled a bit. It was kind of funny seeing Celestia desperate, and she hadn't had the same idea they did. Looking at Twilight now, they wouldn't have been able to tell that she peed herself because her shorts were soaked with sweat anyway. And they smelled only of farts.

After all the extra water they had drank, Luna and Cadence were feeling the urge to pee again, so they just peed midflight, out of sight of anyone. It would rain down on the area below them, but it wouldn't likely land on any ponies, and they'd mistake it for a rainfall, especially since their pee was very clear.

They reached Los Pegasus, and played. Twilight realized, with her sports outfit already soaked with sweat, it was impossible to tell she had wet herself. Only the Cloudsdale pegasi had noticed, but she didn't go there much anyway and hoped it wouldn't be mentioned again, plus they still loved her. She let out a loud, wet fart that lasted eleven seconds, but she didn't mind. She was just relieved that her bladder was empty and her accident unnoticeable.

Celestia really needed to go. She held it for as long as she could, still trying to play the game. Twilight was playing better now, and even with Celestia hindered by her desperation, they were an even match. Twilight's team won by the time this game was over.

"The last game is in the Crystal Empire," said Luna. "Since we set some spare time to rest from such a long flight, you can go now."

Celestia was so relieved to hear this. She ran to the nearest outhouse, but it was locked. She frantically did the pee dance, banging on the door. Twilight giggled a bit. Though she knew it wasn't much fun for Celestia, she had, after all, gone through the same thing, and she suspected why Luna and Cadence had suddenly started playing better. And if Celestia wet herself now, only the other princesses would know.

Finally, Celestia could hold it no longer. She blushed lightly as she peed in her shorts, soaking them further. It just dawned on her that her shorts were already wet, so no one in the Crystal Empire would know the difference.

"Ahhhh, that's better," Celestia sighed in relief as she continued peeing, sitting down in her puddle. She peed for just over a minute, and once she was done she stood up, feeling relieved and having enjoyed her accident a bit.

"Looks like you couldn't hold it as long as Twilight," Luna teased, slapping Celestia's butt lightly. "She peed longer than you."

Twilight blushed a little, and Celestia giggled a bit.

"This is the third time I've wet myself on one of these volleyball tours," said Celestia. "Next time I'll definitely space the games out enough to allow bathroom breaks."

Although she DID plan on peeing herself in the middle of their flights if she was already soaked with sweat, as she suspected Luna and Cadence had done.

As did Twilight. She raised her behind in the air and farted loudly, much to her amusement.
