Applejack and Rarity's Embarrassing Day

Rainbow Dash was about to play a soccer game against a team which had Lightning Dust on it, and she was downing one bottle of cider after another.

"Darling, you really shouldn't drink that much before a game," said Rarity.

"Yeah," said Applejack. "You might wet yourself again."

"I can hold it! This isn't the first time I've had this much to drink before sports." She drank another cider.

"I bet you do wet yourself," said Applejack.

"As do I," said Rarity.

"And I bet that I won't!" said Rainbow Dash.

"Wanna make it an actual bet?" said Applejack.

"Name the terms," said Rainbow Dash.

"If you wet yourself, you have to wear a frou frou outfit until I say so," said Rarity.

"And do all my work around the farm for a day with no bathroom breaks," said Applejack.

"And if I don't, you two have to do anything humiliating I want you to for a day!" said Rainbow Dash.

"You're on!" said Applejack and Rarity. They shook hands with Rainbow Dash.

...

Rainbow Dash emerged from the nearest bathroom after the game, looking immensely relieved.

"I made it!" she said, although she had been so desperate during the game she thought she wouldn't.

"Really?" Applejack felt the crotch of Rainbow's shorts. They were dry.

"Damn it! It's true. We lost."

"Oh no..." Rarity was dreading what was to come.

...

Next day they met in front of the school. Rarity wearing her usual purple skirt, and Applejack wearing short, tight jean shorts. Rainbow Dash wearing her usual compression shorts under a skirt.

"Today's the day you do your part of the bet," said Rainbow Dash. "First things first. If you have to go, go in your underwear. Or shorts, in Applejack's case. You are not allowed to even touch a toilet until the end of the day, or until I say so."

"Are you out of your mind?" said Rarity.

"We shook on it!"

"Fine. But I'll try to hold it in all day."

"Good luck with that!"

...

For two classes, the entire school was outside, with each class separated into teams that were running around the racetrack to practice for a big race coming up. Rainbow's class ran their race first.

"Perfect," said Rainbow Dash as she walked up to Rarity and Applejack. "Now, expose your underwear to everyone."

"I beg your pardon?" said Rarity.

"Ah ain't doin' that," said Applejack.

"Then you shouldn't have been so sure I'd wet myself at the game!"

Rarity and Applejack sighed, and stood in a spot where everyone could see them. Rarity lifted her skirt up, turning away from the eyes staring at her purple panties. Applejack pulled her shorts down, exposing her red panties to everyone.

Everyone burst out laughing, and Rarity and Applejack blushed beet red.

"Now, sit on that bench and spank each other. Applejack, when it's your turn, pull Rarity's skirt up. And keep your shorts down until both of you have given each other ten spankings."

Applejack sat on the bench first and put Rarity over her lap, lifting her skirt up so her underwear was visible.

"I can't believe we're doing this," said Rarity, blushing.

She squealed as Applejack brought her hand down on her rear.

After ten swats, Applejack stood up. Rarity sat on the bench, put Applejack over her knees, and spanked her ten times. Applejack would have enjoyed it if everyone wasn't watching.

...

By lunchtime, Rarity and Applejack needed to pee really badly.

"If you have to go, the bathroom's over there," said Sunset.

"We had a bet, and I won, so they have to do anything humiliating I say!" said Rainbow Dash.

Applejack realized she probably wasn't going to make it, so she let it all out in her shorts. The sound of her peeing was easily audible, causing Rarity to leak a little.

"If you hold it until next class, go there," said Rainbow Dash.

Applejack's jean shorts were soaked, and she was blushing lightly.

...

Next class, as soon as they were doing their assignments, Rarity looked around to make sure no one was looking, and peed in her dress. It was so humiliating. The hissing sound was only slightly less audible with her. The crotch and butt of her dress became soaked, as did her purple panties, and pee dripped off her seat into a puddle under her.

Some of the other students noticed and snickered, including Rainbow Dash. Rarity blushed beet red.

...

After school, Rainbow Dash brought them each a cookie. Looking at her suspiciously, they ate them.

"Those cookies had lots of fart powder in them! Your final task is to fart in each others' faces! Then our bet is done."

"Ugh. I am above such-" Rarity felt a pressure in her bowels. "Fine, let's get this over with. Applejack, get next to my rear."

Applejack did as she was told, and Rarity let out a loud fart, blowing her skirt back.

"Hoo, Rarity, that smells just as bad as mah farts!" said Applejack.

Rarity blushed.

After a few more farts, Applejack was feeling the pressure now. "Time to switch!"

They did, so Rarity was now next to Applejack's butt, and Applejack farted loud and deep-pitched into her face.

"Ugh, that's just vile," said Rarity.

Applejack felt no shame about this.

They kept switching around after a few farts, while Rainbow Dash laughed, and so did anyone who happened to walk by or be standing nearby.

After about fifteen minutes, their gas was gone.

"That's it," said Rainbow Dash. "That was so hilarious! Next time you'll have a little more faith in how long I can hold it!"

"We are NOT making a bet like that again," said Rarity.

...

On Rainbow Dash's next soccer game, once again she drank too much cider...

...and once again she made it.

"We are DEFINITELY not making a bet like that again," said Rarity.

Applejack nodded in agreement.
