Author's Note

This chapter contains a few farts. If you really feel it made it harder to enjoy this, I'll remove them. And as usual, stretchy scenarios, so don't take too seriously.

Also, Equestria Girls. Rarity's outfit is from The Other Side. Will contain allusions to a headcanon of Rainbow Dash and a set of pictures I did on derpibooru with Fluttershy. And Rarijack ship.

Don't be too harsh about the quality, I know it sucks, but I haven't written for an audience besides the people who really love my stories in a long time. And if it contradicts any previous EqG chapter, say it's in another AU from there.

Rarity's Unitard Desperation (EqG)

Rarity was wearing her skintight black sleeveless unitard as she was going for a walk with Applejack. Applejack was wearing a white and green T-shirt and short, tight jean cutoffs.

It was a hot summer day, so Rarity was sweating a bit. She and Applejack drank some large bottles of water and lemonade to stay hydrated, and Applejack got them some extra large slushies.

They went for a long walk, eventually to the park. They sat on a bench to rest for a bit, enjoying the warm weather. And being with each other.

Rarity felt a pressure inside her she knew all too well, but never wanted anyone else to know about it. She let out a long, silent fart, and was barely able to keep from sighing in relief.

Applejack sniffed the air around them. "Phew, what's that smell?"

Rarity blushed. "I don't know."

Applejack looked at Rarity and saw how red her face was. She put two and two together, but said nothing.

Eventually, Rarity said "I need to use the bathroom." She got up and ran down the path towards the park bathroom. Unfortunately she slipped on a banana and went flying through a hole in a tree, so that her top half was coming out one side of the tree and her bottom half out the other.

Applejack walked over to Rarity. "You all right there, Rares?"

Rarity tried to get out forwards, pressing her hands against the tree trunk. "I'm stuck! Applejack, be a dear and help me."

"Will do, suagrcube." Applejack grabbed Rarity's legs and pulled then as hard as she could, but Rarity was firmly stuck inside.

After about a minute, Rarity felt another jolt from her full bladder. "This isn't working, Applejack. You'll have to push me."

"Gotchya." Applejack's heart was beating really fast as she looked at Rarity's butt. It looked so sexy in that skintight outfit and she couldn't wait to push on it.

"Applejack, I know my rear end is quite a sight to behold, but I really have to go!"

Applejack blushed lightly and started pushing on Rarity's butt. It felt so soft, and she loved the feeling of it in her hands.

Rarity liked it too, despite her situation.

Applejack pushed as hard as she could, feeling invigorated by her excitement at being this close to Rarity's butt.

Then Rarity accidentally farted loudly. FFFFFFFRRRRRRRRRRRT! She blushed beet red. "My apologies, Applejack."

"It's all right," said Applejack, inhaling deeply through her nose. "Let it all out." She kept pushing.

"Ooh! Don't say that! My farts aren't the only thing I'm holding in! I can't even hold myself!"

Applejack continued to push on Rarity's tush for a few more minutes, and Rarity let out a few more loud farts involuntarily.

"It's no use," said Applejack. "You're not budgin' an inch. I'll have to go get my geode. Then I can get you out."

"That might be our only option," said Rarity. *pppprrrt* "Just please, don't take all day. I still need to use the bathroom rather badly."

"Just hold it till I get back," said Applejack. Her house was a fair distance away but she ran as fast as her legs could carry her. She needed to pee really bad as well, she had drank as much as Rarity, but she didn't want to waste a second, she didn't know how long Rarity could hold it, plus she used this as motivation to run faster.

Rarity moaned and kicked her legs as she waited for Applejack. She was in desperate need of a bathroom, but couldn't do anything about it until she was out of this tree. She hoped Rainbow Dash hadn't been this distressed while waiting inside of a snowman for two days. She reminded herself, Rainbow put herself in that situation and could have left it any time she wanted. Just like her to not mind going to the bathroom on herself. She would always fart shamelessly and pee in her swimsuit, sometimes while it was still dry. But she still liked her. Just as she absolutely adored Fluttershy, who loved peeing her wetsuit while wearing spandex green shorts underneath. She was so used to that she never thought of it as weird. But Fluttershy was always embarrassed whenever she had an accident in her dress, or her shorts when she wasn't wearing a wetsuit over top, and Rarity really didn't want to wet her unitard.

...

Applejack ran into Rainbow Dash on the way home, wearing a blue sports bra and short skintight spandex shorts, and dripping with sweat, evidently having run several laps.

"Hey Applejack, you're running really fast," said Rainbow Dash. "Wanna race me?" She took a large drink of water.

"No thanks," said Applejack. "I gotta pee somethin' fierce." So did Rarity, but her desperation wasn't pretend at all and she hoped she could get by with just it and not mention how badly Rarity needed to pee.

"So? You'll be wet anyway from sweating a lot, and you can use your desperation to motivate you to run faster and give me a good challenge!"

"Well..." She knew she should help Rarity, but her competitive nature started getting the better of her. Plus, she couldn't think of any excuses to cover Rarity's predicament, she wasn't good at that. "All right, but just one race."

Applejack and Rainbow Dash raced around the track. Applejack ran as fast as she could, not only to beat Rainbow Dash, but also to help Rarity get free before she had an accident, and then find a bathroom herself.

Applejack won the race, which surprised and impressed Rainbow Dash. "Wow, you must've really needed to go to run that fast."

"You don't know the half of it," said Applejack, drinking a large bottle of water, knowing she needed it despite the potential consequences. She was as soaked with sweat as Rainbow Dash. "Now can I go?"

"Sure," said Rainbow Dash.

As soon as Applejack sprinted off, Rainbow peed in her already-wet shorts, sighing in relief. She always did this while running laps and sweating a lot, drinking lots of water to stay hydrated. Her pee was clear anyway so it didn't even smell and could not be distinguished from sweat.

...

Rarity continued to fidget and kick her legs inside the tree. What was taking Applejack so long? She needed to pee really badly but couldn't get her unitard down in her current position or hold herself. She accidentally let out a few more farts as she desperately tried to hold her overflowing bladder. She had never been this desperate to pee in her life.

"Ooh... hurry up, Applejack!" said Rarity, crossing her legs. "I can't hold it much longer..."

...

Applejack was in view of her house when Pinkie jumped out.

"Surprise!" she said.

Applejack was startled and peed a little, but you couldn't tell because of the sweat. "Pinkie, I really gotta go to the bathroom!"

"Oops... Sorry, Applejack," said Pinkie. "I was just in the area to drop off an invitation to a big party at Sugarcube Corner!"

"Great," said Applejack, holding herself and doing the pee dance. And she knew it wasn't only her bladder on the line here. "Listen, Pinkie, I'm really lookin' forward to it, can you give it to me real quick so I can find a bathroom?"

"Sure thing," said Pinkie. She gave Applejack her invitation, and Applejack dashed back to her house. She put the invitation on the counter and then grabbed her geode. She could've taken some extra time to use the bathroom, but she knew how desperate Rarity was and wanted to help her, so she ignored her own bathroom needs for now and ran back outside.

"That was fast," said Pinkie. "So will you be able to make it?"

"I'm not sure," said Applejack. "I really gotta go." She held herself and pee danced.

"I meant to the party. And didn't you pee back inside the house?"

"Yeah, well... I'm kinda in a rush to get back to Rarity."

"Ooh! Want me to make a delicious cake for her?"

"That won't be necessary, now's REALLY not a good time to keep her waiting. I'm runnin' behind as it is."

"Are you sure? It'll be real tasty!"

Applejack sighed. "Make a cake and text me when you're done so I can pick it up."

"Will do!" Pinkie walked away. Applejack wasted no time in running towards the park, but was forced to stop when Fluttershy was helping some ducks cross the road.

"Can't you do that a little faster, Fluttershy?" said Applejack. "I really gotta pee!" And so does Rarity...

"Oh my. Please hold it just a little longer, Applejack," said Fluttershy. She hoped the country girl wouldn't have a humiliating accident. She was prone to pee accidents, usually from being scared or startled, and it was always embarrassing, even though she'd usually get over it within the hour, and even though she was unashamed of peeing her wetsuit and enjoyed it greatly.

As soon as the ducks were across, Fluttershy said "All clear. I hope you make it."

Applejack ran as fast as she could. "Hold on Rarity, I'm comin'."

...

Rarity was crossing her legs even tighter than ever, sweating with the effort of holding it in.

"Where are you, Applejack?" she said. "I'm about to wet myself!"

She leaked a little, and she whimpered and started kicking her legs frantically. She didn't know what she could do at this point to hold it. She was about to burst. Even if Applejack arrived right now, she likely wouldn't make it.

Her desperation combined with her nervousness at wetting herself was too much for her. Rarity's overflowing bladder gave out and she started to pee uncontrollably. She stopped kicking her legs as she felt her crotch grow warm and wet, and the warm wetness running down her legs. She was painfully aware of the pee sound, and unlike with Rainbow Dash's pee, she could smell it. She blushed lightly at peeing herself, but she couldn't deny the relief felt good, and couldn't help but let out a sigh.

Applejack arrived at the area. "I'm here, Rare... Oh, apple fudge."

Rarity blushed profusely as she continued to wet her unitard. The girl she liked was watching her have an accident. "I... I couldn't hold it..."

"It's all right, Rarity," said Applejack. "It was my fault. I got distracted when Rainbow Dash challenged me to a race."

"Applejack!"

"I know, I should've just turned her down, but I couldn't resist, plus I didn't want to tell her you were on the verge of wettin' yourself too. I'm real sorry."

"Oh... I can forgive you," said Rarity. She knew how competitive Applejack and Rainbow Dash could be and appreciated that a part of this was to hide her desperation. She knew Applejack wasn't too good at making stuff up. Looking over her shoulder, she noticed Applejack's discomfort. "Are you all right?"

"I need to pee real bad too, and I didn't stop for a bathroom break at home. I wanted to make up for lost time and get you out of that tree as fast as I could."

"Awwww," said Rarity. "You'd risk wetting yourself for me? That's so sweet. I hope you're not put off by... this..." She was still peeing, her stream going steady and showing no signs of stopping.

"You want my honest opinion?"

"Let's hear it." Rarity braced herself for the worst.

"You look real cute wettin' yourself."

Rarity blushed again, this time out of flattery. "I do?"

"You bet your behind you do." Applejack slapped Rarity's butt, which instantly sent her through the hole in the tree. She landed facedown and peed for another 10 seconds or so. When she finally finished, she got to her feet with as much dignity as she could. Her crotch, butt, and legs were soaked and smelled of pee but she didn't mind anymore.

"Thank you, darling," said Rarity, kissing Applejack on the cheek. "Now, find a bathroom before you wet yourself."

"Too late..."

Applejack was peeing her sweat-soaked shorts. She sighed in relief as the rivers gushed down her legs while a hissing noise louder than that of Rarity's stream could be heard. Rarity couldn't help but like the sight of this. She could understand what Applejack meant.

When Applejack finished, Rarity asked "Are you all right, darling?"

"I'm fine," said Applejack. "A little pee doesn't bother me a whole lot. How you holdin' up?"

"Much better," said Rarity. "It was almost fun wetting myself, and you certainly don't mind." She let out a loud, wet fart, and blushed lightly, but giggled.

"How bout we get you back home before someone sees you like this," said Applejack.

"Or... Rarity dove into the pond, and came out soaking wet. "There, now no one can tell I wet myself, and you're already dripping with sweat so that won't be an issue for you."

They continued to have fun and let the summer sun dry them. Eventually, after restocking on drinks, they rested a while, sitting on the grass next to the pond.

"So, it was almost fun wettin' yourself?" said Applejack. Her shorts, though dry, smelled of pee.

Rarity blushed lightly. "If I can get by how embarrassing and unladylike it is, the relief combined with the warm wetness almost felt... divine. You don't think that's weird, do you?"

"Not if you don't think it's weird that I like the sight of you peein' yourself. You can do that around me all you want and I promise I won't tell no one."

"You're such a sweetheart, Applejack." Rarity let out an explosive wet fart and blushed lightly.

"Phew, Rarity," said Applejack, fanning the air with her hat.

"Pardon my unladylike display."

"It's all right," said Applejack. "I like to see you fart too. Somethin' about the contrast of a ladylike girl doin' somethin' like that. And again, I promise I won't tell."

Rarity leaned her head close to Applejack. A long, deep-pitched fart made its way out of her, but she didn't react to it, and Applejack loved it.

Then Rarity pulled away and said "I need to use the bathroom."

Applejack started tickling Rarity, who kicked her legs as she laughed uncontrollably.

"Hahahahaha! Applejack, stop! Hahahahahaha! I'm gonna... HAHAHAHAHAHAHA!"

Soon Rarity was peeing her outfit again. She continued to laugh and kick her legs as Applejack tickled her. Both of them were enjoying this a lot.

Applejack stopped when Rarity finished wetting herself. Rarity caught her breath, felt her wet crotch, and blushed, but giggled. "That was fun," she said.

"Ooh, I gotta pee too," said Applejack.

Rarity tickled Applejack, who lay facedown kicking her legs and banging her fist on the ground.

"Hahahahahaha! Rarity, cut it out! I need to pee! Hahahahahaha!" But of course she didn't really want her to stop, and soon a hissing noise could just be heard over her laughter as she wet her shorts for the second time today.

"You look rather nice wetting yourself as well," said Rarity when she stopped tickling.

Applejack got to her knees. "Aw shucks, Rarity."

Rarity farted loudly and giggled. She was glad that Applejack hadn't gotten back in time to keep her dry. "Would you like to stay like this until someone comes along, and then rinse off in the pond if they do? If we haven't dried by then?"

"Sounds good to me."

Rarity lay facedown, striking a sexy pose for Applejack. She farted several times, but didn't mind, she knew Applejack liked it, and it was kind of fun to fart.
