Author's Notes:

This chapter was done by request of one of my friends and supporters. I never really thought about the Shadowbolts much. I even forgot their personalities, and had to be reminded that Indigo Zap is as competitive as Rainbow Dash.

Rainbow Dash threw her Badminton racket to the ground.

It was the middle of summer, and Rainbow Dash and Indigo Zap had been getting into some fierce competition.

Two days ago, Rainbow had beaten Indigo in a race on foot, and at soccer. Yesterday, Indigo had beaten Rainbow in a bike race and at volleyball.

Today, Rainbow had beaten Indigo in a rollerblading race, but lost to her at Badminton.

Rainbow Dash was wearing short, skintight shorts the same shade of blue as her hair, and a matching midriff tank top, and Indigo Zap was wearing a similar athletic outfit, but purple. They hadn't changed out of them or washed since they started their sweaty competitions, so they smelled bad.

"I win," said Indigo.

"Then I guess we're tied," said Rainbow Dash.

"We need a tiebreaker so I can prove I'm the better athlete than you."

"I can think of one."

"And what is it?"

"A holding contest."

"A what? You're kidding, right?"

"I'll have you know I won a holding contest against all my friends. Even Applejack."

"You honestly think you can hold it as long as me?"

"You bet I can!"

"You're on!"

They walked to Indigo's house to do the holding contest somewhere where no one could see. As they walked, anyone they walked by sniffed and recoiled at their smell.

"Think we should take a shower after this?" said Rainbow Dash.

"Once our competition's over," said Indigo. She snickered. "You'll DEFINITELY need a shower once we're done."

"You'll be the one who needs to wash all the pee off her!"

They reached Indigo's house, where they drank several cups of water and cans of soda, each making sure the other drank as much as them. Then they waited in the backyard, drinking a new glass of water every 20 minutes.

Finally, they both started to feel an urge to pee. But, they wanted to hide it from each other, and successfully hid any signs of it.

After about an hour, they were both starting to fidget a little, but trying to keep their movement to a minimum.

"Do you feel like pissing yourself yet?" said Indigo.

"Not even a little bit," said Rainbow.

Over the next hour, they became more desperate, as their bladders slowly became more full from all the fluids they had drank. Rainbow Dash had an idea of how long she could hold it, while Indigo was slightly nervous as she had never done this before.

Once the second hour was over, they stopped drinking every 20 minutes.

"If you can hold it for another hour, we'll get to challenges to make it more difficult," said Rainbow Dash.

"Isn't that cheating?" said Indigo.

"Not if I have to endure the challenges too."

"Right."

They started to hold themselves and fidget more. Soon, Indigo reached a point she had never known before. And she had once been pretty desperate during a soccer game after drinking several energy drinks before it. She thought she had barely made it, but now she was sure she had plenty of time to spare.

They both lasted the third hour, but were now unable to keep from fidgeting.

"All right, challenge time!" said Rainbow. "Let's see, what was the first challenge? Right. 15 situps! No, wait, without anyone else there'd be no way of telling which of us wets herself first. All right then."

She walked over to the hose and turned it on so the sound of running water could be heard.

Indigo felt a lot more uncomfortable at this. She found it a lot harder to hold in. But, she figured Rainbow Dash must be having just as much trouble.

Sure enough, Rainbow was now holding herself as she walked back in front of Indigo and resumed fidgeting.

Over the next hour, they went from fidgeting to pee dancing, holding themselves with both hands. Indigo could feel waves of pee sloshing inside her.

"I really gotta go!" said Indigo, blushing a little as she had let slip how desperate she was, which might give Rainbow Dash a boost.

"So do I," said Rainbow. She honestly wasn't sure who was going to win this. She really needed to go, but Indigo couldn't be doing much better.

"Aah!" Indigo leaked a bit into her shorts. Initially she thought she had lost, but then she realized she was able to hold the rest of it.

"Yeah, one thing I forgot to specify," said Rainbow Dash. "You leak a little when you're really desperate. But, only once you start peeing yourself all the way, you lose. Leaks that stop after like ten seconds or less don't count." She moaned as she leaked a bit herself.

Their leaks became longer and more frequent over the next half hour. At the end of which they both felt like they were about to burst. Around this point was when Rainbow had them pee for five seconds, but she wanted to see it to the end this time.

"Ugh..." said Indigo, dribbling into her shorts. "I'm not sure how much longer I can hold it..."

"I hate to admit it, but... I'm pretty close to bursting myself," said Rainbow Dash, whose shorts were also growing damper by the second. She knew she was only minutes, maybe seconds away from wetting herself all the way.

"Uhhhh..." Indigo felt another leak, but this one she could not stop. She desperately tried to hold the flow back but it was no use. She was wetting herself full force. Her skintight purple shorts became soaked as rivers of pee gushed down her legs, and a steady stream passed through between her legs and onto the grass below. Indigo blushed beet red. Not only was she wetting herself, but she also lost her final challenge to Rainbow Dash.

Rainbow Dash could see that Indigo had lost. "Yes!" she said, and she let go and started peeing full force, sighing in immense relief as she flooded her shorts and soaked her beautiful legs. "Ahhhhhh..."

"Why didn't you try to find a bathroom?" said Indigo.

"I kind of like the feeling. Besides, I didn't want you to be the only one to wet herself today."

Indigo was grateful for this. She sighed, enjoying the warm release as she kept peeing. She could now smell the pee in addition to hearing the sound of her stream soaking her shorts. She blushed again at how obvious it was that she was using her shorts as a toilet, but as Rainbow Dash was the only witness, and she was doing the same, she closed her eyes and let herself enjoy the new sensation, as well as the relief.

After about two minutes, they both finished, loving the sense of relief after holding it for so long. Indigo felt how wet her shorts were, and sniffed her armpit, wincing at her own smell. "We should really wash, huh?"

"Yeah."

A few minutes later, Rainbow and Indigo were both sitting in Indigo's bathtub full of soapy water, still wearing their smelly exercise outfits that they had peed in.

"I guess you win this time," said Indigo. "But, I'll try harder next competition."

"I look forward to it," said Rainbow.

They shook each other's hands, and started to scrub each other with a soapy sponge.
