Rainbow and Rarity's Embarrassing Day

"Hey Applejack, I challenge you to an arm wrestle! Without your geode!"

"You're on! Ah can beat you even without super strength."

"That's not what happened last time!"

"I'll have to agree with Rainbow Dash," said Rarity.

"You're takin' her side?" said Applejack.

"Why don't we take a bet?" said Rainbow Dash.

"That sounds smashing," said Rarity. "If Rainbow Dash wins, you have to wear a frou frou dress for a week."

Applejack shivered slightly, but regained her composure, confident that she could beat Rainbow Dash.

"And you have to pee in it," said Rainbow Dash. Rarity gave her a dirty look, but nodded.

"And if ah win," said Applejack, "neither of you can wash, change clothes, or use deodorant or toilet paper for a week."

Rarity gasped.

"And you're only allowed to take yer shorts and panties off to go to the bathroom. After which you must put them back on."

Rainbow Dash was wearing her usual outfit, black compression shorts under a pink and white miniskirt, with a white T-shirt and blue jacket on top, while Rarity was wearing a light blue tank top and short, skintight, purple shorts which looked as lovely on her as her dress.

"And, you gotta do anything else ah say relevant to that, though ah won't tell you to wet yourself or mess yourself or anything like that."

"You're on!" said Rainbow Dash.

Rarity hesitated, but, confident Rainbow Dash would win and eager to see Applejack dress fancy, said "Deal!" She and Rainbow Dash each grabbed one of Applejack's hands and they shook on it.

Applejack set her geode down and arm-wrestled Rainbow Dash. Rainbow looked like she was about to win... and then Applejack forced her hand to the ground.

"Oh dear," said Rarity.

"Ha!" said Applejack. "Now, we shook on it so you know what you gotta do. And starting from Day 3, I'll be sniffin' your butts to see if you've been breakin' our deal and usin' toilet paper."

"Can't you sniff my behind when it doesn't smell bad?" said Rarity.

"Ah prefer when there is a smell." Applejack blushed lightly.

"No problem for me," said Rainbow Dash. "It's not like I haven't gone several days without showering before!"

"I haven't forgotten," said Rarity.

...

The next day, Applejack called Rainbow Dash and Rarity to a racetrack, with several bottles of water and a dispensible barrel of cider. Both were still wearing their outfits from yesterday, and Applejack was wearing a green T-shirt and a pair of jean shorts.

"Ah want you to run a long race with me. Ten laps around here. You can stop at the end of whatever lap you want to take a drink and stay hydrated."

Rainbow Dash and Rarity were thankful for this, because it was a hot summer day.

"I'm gonna love this!" said Rainbow Dash.

"Oh, and you can't use yer geode."

"Fine by me." Rainbow set her geode on top of the cider barrel, and then they stood at the start/finish line.

"On yer marks... get set... go!"

They ran as fast as they could. Rainbow Dash was in the lead, Applejack close behind, and Rarity at the rear. They were sweating profusely by the end of the first lap, and each drank a whole bottle of water.

After each lap, they all stopped for more water. Thankfully Applejack had brought a big case of 24 water bottles, which lasted them for eight laps, and there was enough cider for the last two laps.

Rainbow Dash won. As soon as Applejack crossed the finish line, Rarity sat down, panting.

All three girls were literally dripping in sweat, to the point that they looked like they'd just climbed out of a swimming pool. A puddle of sweat was already forming under Rarity where she sat, and Applejack and Rainbow Dash were sweating a puddle too.

Applejack and Rainbow Dash drank more cider, and then Applejack walked over to Rarity and gave her a cup, which Rarity gratefully accepted.

"Well, at least ah can wash and change after this," said Applejack. "Too bad you can't."

"Good one Applejack," said Rainbow Dash, realizing why Applejack had them run the race on a hot day.

"I am not looking forward to how I'll smell tomorrow," said Rarity.

After resting for a bit, they suddenly felt they really needed to pee from all they had drank. Rainbow Dash grabbed her geode and ran to the outhouse, but in the time it took her to grab it, Applejack had already entered it and closed the door.

Rainbow and Rarity held themselves doing the pee dance while they waited for Applejack.

"Hurry up in there!" said Rainbow Dash. "I really gotta go!"

"So do I," said Rarity.

Finally, Applejack exited the bathroom, looking relieved.

Rainbow quickly ran into the outhouse and shut the door, to Rarity's dismay. She hoped Rainbow's geode would make her pee faster too.

The minutes felt like hours, and Rarity became more desperate.

Just as Rarity started leaking into her already-wet shorts, Rainbow Dash finally opened the door and walked out.

Rarity ran into the bathroom, leaking for four seconds as she fumbled with her sweaty hands and finally pulled her shorts and panties down before sitting on the toilet.

She exited the bathroom, relieved, though her shorts smelled slightly of pee from how much she had leaked before.

...

Day 3, Applejack met up with Rainbow Dash and Rarity. Applejack was wearing her usual jean skirt, Rainbow Dash and Rarity were wearing their same outfits. The sweat had long dried off them, but they were starting to smell. They were scratching themselves as well, especially their butts, for they had both taken a dump at least once before today, and not used toilet paper as Applejack had said. As such, their underwear was pretty dirty.

"First things first," said Applejack, and she sniffed Rainbow's butt. "Yup, smells pretty bad." She sniffed Rarity's butt. "Did you pee in your shorts?"

"I may have leaked a little, but I made it on the whole," said Rarity, blushing a little.

"Now let me sniff your armpits."

Rainbow lifted her arms and Applejack sniffed. "You're gettin' there." She sniffed Rarity's armpit. "Pretty good for only three days."

"You mean we smell pretty bad," said Rarity.

"Only four days left," said Applejack.

...

On Day 4, all seven of the girls were eating a meal that Applejack and Pinkie Pie had prepared together. The other girls were aware of the bet they had taken.

"Phew, you two do smell bad," said Twilight.

"I don't mind," said Rainbow Dash, scratching her butt.

"I certainly do," said Rarity. She sniffed her armpit. "I can't wait to take a shower three days from now."

Pinkie had put fart powder in Rainbow Dash and Rarity's food. In minutes, it started to take effect.

Rarity tried her hardest to hold it in, even though she suspected how much she and Rainbow Dash already smelled might drown out the smell of the fart, and she did know how to fart silently.

Rainbow Dash farted loudly and chuckled.

"Rainbow Dash!" said Rarity, secretly appreciating this so she could let out a silent fart of her own.

Rainbow farted more, each fart ranging from three seconds to nine.

"I'm really gassy today," she said. She paused to fart for five seconds. "Awesome!"

Rarity, in the meantime, felt the pressure get so intense she couldn't keep it silent anymore. She let loose with a series of boisterous farts, much shorter than Rainbow Dash's, from one to two seconds, but just as loud and smelling just as bad.

Pinkie laughed so hard she wet her jean shorts. She didn't even blush, for she was still laughing too hard.

"Pinkie Pie, did you put..." FFFFFRRRRT! "something in our food?" said Rarity.

"I put fart powder in there," said Pinkie once she got a hold of herself. She felt her wet shorts and blushed lightly.

Rarity felt bad for her so she decided to let it slide this time.

By the end of the day, Rainbow Dash and Rarity not only smelled like four days of sweat, but farts as well.

...

On Day 5, Applejack sniffed Rainbow Dash and Rarity again. By now they had flies buzzing around them.

"You definitely smell even more than last time," said Applejack after sniffing Rarity's butt. Then, as Rarity scratched her butt vigorously, Applejack sniffed Rainbow Dash's butt.

PPPPPFFFFFFFT!

Applejack fell on her butt as Rainbow Dash laughed at her own fart. Applejack stood up and sniffed deeply.

"Did you put Pinkie up to it yesterday?" said Rainbow Dash, even though this fart had nothing to do with fart powder, which had worn off.

"She suggested it and ah thought it'd be mighty fun."

"Yes, it's so very amusing to humiliate myself with something so unladylike and smell even worse than I would without it, which is saying something," said Rarity.

"Actually, it is amusing," said Rainbow Dash.

After Applejack sniffed both their armpits, which, again, smelled worse than two days ago, she said "Now take off your shoes and socks so I can sniff your feet."

Does she have a foot fetish too? thought Rarity as she took her shoes off.

Applejack sniffed Rarity's feet, which smelled just like her armpits. Rainbow Dash giggled as Applejack sniffed her feet next, inhaling deeply.

...

Day 6, they hung out with the other girls again. They smelled really bad by now, from not washing, the sweat of the summer heat, the farts from two days ago, and not using toilet paper (their underwear was very dirty by now). But their friends were able to put up with the smell because they really liked them. Fluttershy even gave them a hug.

...

On Day 7, Applejack met up with Rainbow Dash and Rarity in the afternoon.

"Do ah even need to sniff you?" said Applejack. "Ah can smell you from here."

Rainbow Dash sniffed her armpit. "Yeah, we smell really bad now! I've even been eating stuff that makes my poop wetter." She chuckled as she scratched her butt.

"Too much information, Rainbow Dash," said Rarity. Of course her panties were just as dirty as Rainbow Dash's, maybe even dirtier.

First Applejack sniffed their armpits. Then she sniffed their feet again.

"Damn, you do stink somethin' awful." But she looked like she enjoyed the smell rather than being disgusted by it.

Then she sniffed Rainbow Dash's butt. "Phew, you sure you didn't soil yourself?"

"Not really," said Rainbow. "Although... I think I'm going to if I don't get to a bathroom soon!" Just now she had gotten an intense urge to pee and poop from all the cider she drank this morning and all she had eaten with the other girls yesterday.

"Just hold it until ah smell Rarity." Applejack sniffed Rarity's butt. "Phew, you smell even worse than Rainbow Dash!" She slapped Rarity's butt lightly.

"Is that so?" said Rainbow Dash. She stopped trying to hold it in, closed her eyes tight, and started to push. "Hrrrrrgggggh..."

She sighed in relief as she released a wet brown mess into her shorts, while simultaneously peeing, waterfalls gushing down her legs.

Rarity wrinkled her nose at the stench. "Rainbow Dash... did you just... go to the bathroom in your shorts?"

"Now I smell worse than you!" said Rainbow, chuckling and still peeing.

"I did not know this was a contest, and if so, I'm glad to lose it." At these words, she realized she was very grateful to lose a contest of smelling bad, overriding her disgust for Rainbow Dash wetting and messing herself. She'd give her a hug if she wasn't concerned about Rainbow peeing on her.

"That's kinda cheatin'," said Applejack. "For that, you gotta stay in that outfit for all of tomorrow!"

"Oh come on!" said Rainbow Dash as she finally finished peeing.

...

That night, Rarity took the longest and most satisfying bubble bath, and then shower, of her life, still wearing her dirty, smelly outfit, for it needed as much washing as it could get. She did not fart in the tub. Not only was she above deliberately doing something so unladylike, preferring to fart silently out of the water and away from others, but she didn't even have to fart now. After finishing her shower she changed into her pajamas, put her outfit in the washing machine with extra soap, climbed into her bed, and fell asleep.
