Scenarios will be stretchy as usual. Chalk it up to magic and being based off a cartoon.

Rarity was going for a walk at the park with Applejack. It was a hot day out, so Rarity was wearing a light blue tank top and short, skintight purple shorts. Applejack was wearing a white and green T-shirt and a pair of short, tight jean shorts.

They were sitting on a bench admiring the weather when Rarity felt a stomach cramp. She groaned, feeling the pressure grow more intense. This was starting to get serious, and it wasn't the first time either. Maybe she should have told Sunset about this.

"You all right, Rares?" said Applejack.

"I'm fine," said Rarity.

FFFFFFFFFRRRRRRRRRT!

Rarity blushed at the loud fart that had come out of her.

"That ain't nothin' to be ashamed of." Applejack lifted her leg and let out a slightly quieter fart. "Let it all out. Ah don't mind."

Normally Rarity would have been disgusted at Applejack farting around her, but she was thankful she didn't find her disgusting or unladylike. She hesitated, and let loose with a flurry of more wet farts. Applejack didn't laugh or express disgust, though she did have to resist with the way they smelled, and Rarity wouldn't have blamed her if she did let out a disgusted groan.

As usual, Rarity's farts grew wetter and stinkier over the next few minutes, and she was fidgeting in her seat.

"If you gotta go to the bathroom, just use the outhouse," said Applejack.

"I'm afraid I might.... clog the toilet," said Rarity. "Lately I've been... it wouldn't stop for at least eight minutes. I just got my toilet fixed and I clogged it again. I think I might have that magic disease Sunset had that one time."

"Megahyperscat? I'll ask Sunset to call Princess Twilight and get the cure. We should really think about stockin' up on it."

Rarity let out another wet fart and squealed as she felt her shorts get a little wet. "What am I going to do?"

"There's plenty of bushes to go behind," said Applejack. "Ah won't look. Ah promise."

Rarity ran towards the bushes, farting every few seconds. She looked around for a bush to go behind, but so many of them seemed like someone could walk in at any second.

She let out another sloppy wet fart and felt a load of poop plop into her shorts, squealing again. There was nothing for it but to run behind the nearest bush and hope no one saw her. And if they did, it would be better than messing herself all the way.

She had just started to run for the bush when a man came into view walking his dog. Rarity groaned and ran towards another bush somewhere away from him. She had nearly reached the bush when it happened.

Diarrhea exploded out of Rarity's butt, saturating her shorts and running down the back of her legs. She froze, blushing profusely. She was soiling herself in the middle of the park. She looked behind her, and at least felt somewhat relieved that the man was gone.

The diarrhea continued to flow for ten minutes, before it finally stopped. Rarity had just started to sigh in relief when another boisterous fart made its way out of her and this time hyperscat filled her shorts, overflowing them so that it oozed out of the leg holes, down her legs, and onto the grass below.

Rarity lowered her head in shame. How would she ever explain this to Applejack? She had never been so humiliated in her life.

She let out a few wet farts in between, and her hyperscat did not stop for another 11 minutes. Once she was done, Rarity looked down. She was standing in a huge pile of poop, and her shorts were completely filled with her mess. And she smelled really bad.

She stood there for minutes, terrified to approach Applejack in the state she was in. But when she heard Applejack calling her name, she sighed and walked back to her.

"Hey Rares. How'd it..." She saw Rarity's soiled state and stopped. "Oh."

"I didn't make it..." Rarity blushed beet red, starting to tear up.

"There there, Rarity," said Applejack, patting her on the back and doing her best to ignore the smell. "It's all right. I'll get you cleaned up, and if anyone asks, you fell in the mud."

"Wh-what about the smell?"

"I'll just tell them ah farted."

Rarity had never been so relieved to hear a fart reference in her life. As if on cue, she let out another sloppy wet fart, soiling her shorts a little more. She blushed and giggled nervously.

As they walked to Rarity's house, Applejack felt a need to poop as well. She grunted and released a smelly, wet, brown mess into her jean shorts, though much smaller than Rarity's, and not enough to leak through. She sighed in relief.

"Oh, Applejack, darling, you didn't have to do that," said Rarity.

"Ah wanted to. And ah really needed to go just now. Ah don't mind. It actually feels kind of nice." She started to pee in her shorts as well.

Rarity giggled slightly. She should have been disgusted that Applejack was deliberately using her shorts as a toilet, but she knew it was to make her feel better. She gave her a hug, not caring that Applejack was still peeing, and some of it was getting on her.

When they reached Rarity's house, Applejack let Rarity change and shower first. She didn't mind staying in her wet, soiled shorts for another half hour. Rarity showered in her soiled shorts, wanting to wash them as much as she could and rubbing her butt with extra soap.

When Rarity emerged from the bathroom, clean and wearing her usual dress, Applejack took her turn, changing into a pair of jeans Rarity made, and then they spent another fun night together, feeling closer than ever.
