To those who hate this content: Don't worry, this will be the last I fetishize Rarity's Other Side outfit for a while.

Applejack had just finished a day's work at the farm. It wasn't much harder than usual, but her outfit was damp with sweat, which glistened off her legs. She was now walking to the door of Rarity's house for a night of fun. She opened the door and stopped at the sight before her.

Rarity was laying on her stomach, wearing a skintight, sleeveless, black spandex unitard.

"You look smashing," said Rarity.

"So do you," said Applejack. "And ah didn't think anything could look better than your exercise outfit."

"Why thank you. I'm thinking of making another one to wear in public so the world can see it, and it will come with high heels." Rarity was barefoot at the moment.

"That'd be just dandy."

Rarity let out a loud fart. She giggled, and Applejack felt aroused.

"I drank quite a few glasses of water with fart powder in it in preparation for tonight."

"You didn't need that, you're gassy enough as it is. But this'll make it more fun!"

FFFFFFFFFFRRRRRRRRRRT!

Applejack walked closer to Rarity and stared at her butt. She could smell Rarity's farts now, and inhaled deeply.

"Would you like to give me a butt massage?"

"Do you even have to ask?"

Rarity got up on all fours, and Applejack started rubbing her tush. She loved how soft it felt, and it looked just as good in this skintight outfit as it did in her shorts.

Rarity let out a flurry of explosive farts in Applejack's face. She giggled, and Applejack sniffed every time, feeling more aroused with each fart. Rarity also loved the feeling of Applejack caressing her butt.

"Wait a moment," said Rarity after several minutes. Applejack paused, and Rarity positioned herself with her rear end in the air. "Okay, continue."

Applejack rubbed Rarity's behind harder, feeling more aroused at her in this position.

BBBBBBBBBBBRRRRRRRRRRRRRRRRRRRRRRRRT!

"Phew, Rarity," said Applejack, patting Rarity's butt before rubbing it as hard as she could. "That smells worse than that time a horse farted in my face."

Rarity giggled. "Wait, was that too much?"

"Not at all. The stinkier, the better!"

Rarity released several more farts that were shorter, but equal in length. The first two were higher-pitched, and the third was deeper-pitched. Then came a fart that was longer, but airy. Applejack liked these as much as the loud farts.

After several more minutes, Rarity said "That's good enough. I need to use the bathroom."

"Oh really?" said Applejack. She started tickling Rarity's armpits.

Rarity started to laugh, rolling on her back to try to resist Applejack, but Applejack was stronger and tickled harder. Rarity accidentally let out a few farts as Applejack tickled her.

"Applejack! Hahahahahaha! Stop! Hahahahahahaha! I need to pee! Hahahahahahaha!"

Applejack stopped for a few seconds, letting Rarity catch her breath. She grabbed both her feet with one hand and tickled them with the other. Rarity started to laugh harder, and in seconds, a wet spot appeared on her crotch, which rapidly expanded, and soon a puddle began to grow under her. Rarity did not stop laughing, and Applejack tickled her for about thirty seconds after she finished wetting herself.

"Applejack!" said Rarity once she stopped laughing. "You made me pee in my new outfit!"

"Sorry, Rares."

"Oh, it's all right." Rarity punched Applejack's arm playfully. "You know I was going to wet this outfit in bed anyway. That was rather fun."

...

After a night of exercise and watching a movie, during which they farted a lot and drank several cups of cider, Rarity and Applejack climbed into bed, Rarity still in her new outfit which was a little damp around the crotch and butt, and smelled of urine.

Rarity woke up in the middle of the night. The first thing she noticed was that she was desperate to pee. She hadn't used the bathroom before bed. She looked beside her. Applejack was laying on her side, facing her. Rarity positioned herself as close to Applejack as possible without waking her up, lay on her side facing her, and started to pee. She let out a quiet sigh of relief as the crotch and leg of her outfit grew warm and wet.

A puddle formed on the bed, and as soon as it reached Applejack, Applejack let out a moan in her sleep, and a louder hissing noise was heard as Applejack's shorts darkened and glistened with her own pee.

Rarity chuckled to herself at making Applejack wet the bed. Of course, with how much cider she drank, Applejack would have woken up wet anyway.

As soon as she finished peeing, Rarity let out a silent fart, not wanting to wake Applejack up, and went back to sleep.

...

Next morning, Rarity got out of bed. She didn't feel a need to pee after her wetting last night, but her outfit was damp.

She decided to start working on the second version of this outfit, one she could wear in public without anyone worrying about how dirty or smelly it was.

She was about halfway done when Applejack walked in.

"Good mornin', Rarity," said Applejack.

"Good morning Applejack. How was your sleep?"

"It was pretty good. Ah dreamed you led me into a swimmin' pool and we were peeing in it. That was proably when ah wet the bed." She felt her wet shorts.

"About that, you started wetting the bed when I wet my outfit laying right next to you."

Applejack chuckled. "Nice one, Rares."

"Oh, that reminds me, I have to pee now," said Rarity. "But I really want to finish this outfit. It was so fun to make last time."

"Then just go," said Applejack. "You already used your outfit as a toilet twice."

"Good point." Rarity peed her outfit again, while still working on the other one.

"Ah better get back to the farm," said Applejack once Rarity finished peeing.

"All right. I'll see you later tonight?"

"Sure." Rarity let out a boisterous fart. Applejack responded with an equally loud fart, and left.

...

A week later, Rarity and Applejack were at Applejack's house. Rarity had worn this outfit every night with Applejack and not washed it, so it smelled bad.

Applejack was sniffing Rarity's butt, which smelled of sweat, farts, and piss. After a few minutes, Rarity let out a long, loud, wet fart in her face. Applejack chuckled and slapped Rarity's butt lightly.

"Ooh. Applejack, I need to go... bad!"

Rarity stood up and ran for the bathroom. Applejack grabbed a lasso and tied it around Rarity's feet. Rarity fell on her face. Applejack dragged Rarity to a chair and put her over her knee. Rarity squirmed, but she was really excited for what was to come.

Applejack began spanking Rarity hard. After about six swats, Rarity lost control and began peeing. The crotch of her smelly outfit was soaked, and so were Applejack's legs and jean shorts.

"That's extra spankings for peeing all over me!" Applejack slapped Rarity's butt a total of 20 times, and waited until Rarity was done peeing before she got her off of her.

"That never gets old," said Rarity, having enjoyed it greatly. She let out a short, wet fart.

"Now ah think you could use a bath," said Applejack. "You just wet yourself again, and you smell real bad."

Rarity loved it when Applejack gave her baths. "That would be just divine."

Applejack took her into the backyard and threw her in a wooden tub full of warm water, still wearing her wet, stinky outfit. She poured water over her hair and lathered it with shampoo.

Rarity farted in the tub while Applejack was washing her hair. Both of them laughed, and then Applejack scrubbed Rarity's sides with soap, then her back, and then she had her position her butt in the air so Applejack could wash it. She washed it twice as long as the rest of her, and Rarity farted in her face a few times before she was done. After that Applejack washed Rarity's feet, tickling her and causing her to splash Applejack, and then she was done.

Rarity was soaking wet and smelled only of soap. "I think I'll alternate between this outfit and my other outfit each week. Soon they'll be smelling just as bad again."

Applejack slapped Rarity's butt playfully. "Sounds like fun!"
