Aria was with Rarity, and Sonata was with Pinkie Pie. Adagio Dazzle felt lonely and left out. Unlike Aria, Sonata made no secret of what she liked to do with Pinkie, and Adagio was a little jealous, for she secretly wanted to do something like this herself. But, she had no one she was in that kind of relationship with.
She went for a walk around the city, hoping that the nice weather would relax her and make her feel a little better.
As she was walking by Applejack's house, she saw Applejack feeding the pigs. Her back was turned, and her tight jeans showed the outline of her butt perfectly. Adagio stared. She thought Applejack's butt looked cute, but she was too shy to tell her. And she wasn't sure how she'd react.
Then, Applejack farted loudly, and slapped her butt playfully. Adagio couldn't help but let out a moan of unexpected pleasure. Applejack turned around.
"Howdy," Applejack said tentatively, though looking unashamed that Adagio had just seen her fart. "Um... You ain't here to cause no trouble, are you?"
"No... it's just... I... I was walking by, and then I saw you... and..." Her heart was beating faster.
"And what?"
"And... I think you have a really nice butt." There, she said it. She blushed a little.
"Aw shucks, that's mighty sweet of you."
"You think so?" Adagio turned around. "What do you think of my butt?"
"Not bad."
Adagio let out a loud fart, and blushed lightly, giggling nervously.
"You're pretty dang cute when you fart."
"Awwwww..."
They hugged each other, and then did a rump bump.
"Has Pinkie told you what she likes to do with Sonata?"
"Uh-huh. They seem to think it's funny more than anythin'."
"Well... would you like to do that with me?"
"Sure."
"But, I'd kind of like for our butts to be pressed together without any layers of clothing in-between. That could be tricky. It'll be hard enough getting Aria to cast that spell on us in itself. She'd have to see us both naked, or at least bottomless, to do it our way."
"She might not have to. Ah have an idea that would have just as fine an effect."
...
Rarity was shopping at the mall when her cell phone rang. She answered it.
"Hello?"
"Hi, Rarity."
"Oh, hi Applejack."
"Can ah ask you for a favor?"
"Whatever you want."
"Well..." Applejack walked a fair distance from Adagio and spoke quietly so she couldn't hear. "Remember when you and Aria got your behinds stuck together?"
"Yes."
"Me and Adagio want to do the same thing. Except, without any kind of glue. Don't worry, ah didn't tell her what happened between you and Aria, or any of the times that followed. And ah promise ah won't. But ah was wonderin' if you'd be so kind as to make a pair of leggings for the both of us. Two sets of legs combined as one, so we can both put it on, and tight enough that our butts are pressed together."
Not only was Rarity capable of making such an outfit, but Applejack was one of the only four who knew about Rarity and Aria's butt-related activities, and therefore she felt safe asking this of her. Rarity's response was exactly as Applejack expected.
"Ooh! That sounds like an interesting new project. And I know exactly how fun that can be. I'll call you when it's finished."
"One more thing: Don't tell anyone who you're makin' it for."
"You have my word." Rarity hung up.
"So?" said Adagio when Applejack walked back to her. "Is she going to do it?"
"Of course she is."
"I wasn't sure whether she'd want to help us do something like that."
"She doesn't mind Pinkie and Sonata doin' it, unless they fart in front of her. And she'd do anythin' for me as long as it didn't involve doin' anything unladylike herself. She'd even cover herself in mud if it meant doin' somethin' for her friends. Besides, she said it'd be a fun new project cause she ain't done nothin' like it before." Applejack kept her word, not mentioning what Rarity loved to do with Aria.
"You did tell her not to tell anyone else about this, right?"
"Of course."
...
As Rarity was stitching the attached leggings together, Aria sat beside her. "What are you working on, Rares?"
"A new set of pants for a client who wants to press her behind against someone else's," said Rarity. "They will fit both their legs while keeping their rear ends pressed together."
"That sounds fun," said Aria. "Can you do one for us too?"
"I'm already planning on it once I've finished this one. Perhaps even something better."
...
Once Rarity was finished, she called Applejack, and dropped it off at Adagio's house, which only Adagio lived in since Aria and Sonata left. The outfit was skintight and light purple, likely to go with Adagio's usual choice of outfit color. Applejack didn't care what color they were as long as they had the effect she and Adagio wanted.
Applejack and Adagio removed their pants and panties and put the leggings on together. Once they pulled them up, their butts were pressed firmly against each other, with nothing in between.
They loved the feeling immediately. They practiced walking around, sideways, or with one of them walking forward and the other walking backward, all the while rubbing their butts against each other, which gave them immense pleasure.
It wasn't long before it was time for dinner.
"You got any baked beans?" said Applejack.
"Of course I do," said Adagio.
They walked over to the cupboard, Adagio walking forward and Applejack walking backward, their butts rubbing as they walked. Adagio took out two cans of beans, and then walked over to the stove.
While Adagio was cooking the beans, Applejack wiggled her butt vigorously. Adagio giggled, liking the feeling. Applejack's butt was perfect for her, and she wasn't even sure she'd take Sunset's butt over it.
Once the beans were ready, Adagio put an equal amount each on two plates, and she and Applejack wolfed them down.
They turned on the TV, setting the channel to a football game.
"How are we gonna do this?" said Applejack, for it would be hard to sit down exactly right in their position.
"We take turns laying facedown," said Adagio.
"I'll be the first, if that's all right."
They leaned onto the couch and positioned themselves so Applejack was facedown, and Adagio was sitting on her. Applejack liked the feeling of Adagio's butt pressing its entire weight on her own. They turned their heads sideways to look at the TV screen.
Not long into the game, they started to feel the effects of the beans.
BBBBBBBRRRRRRRRRRRTT!
Applejack released a booming fart into Adagio's butt. Adagio moaned in pleasure at the feeling. Then, she let out a long, wet fart of her own.
PPPPPPPPFFFFFFFFFFFFT!
Applejack liked it just as much as Adagio did.
They weren't quite as gassy as Rarity, Aria, Pinkie, and Sonata had been, but they had eaten a lot of beans, so neither could go five minutes without farting.
On the fourth commercial break, they switched. Their butts continued to rub as they got up and positioned themselves so Adagio was facedown and Applejack was sitting on her. Applejack farted louder in this position, and Adagio got even more pleasure out of it. Adagio's butt felt so soft for Applejack to sit on.
...
Meanwhile, Rarity finished her next outfit, which was a pink full body skintight jumpsuit made of underwear material. It had four arms and four legs, enough to accommodate two people.
After consuming water mixed with fart powder, Rarity and Aria tried the outfit on, immediately liking the feeling of her partner's naked rear end against her own.
They rubbed their butts together, and sometimes even walked as far apart as they could so that their butts would smack into each other again.
It wasn't long before they began farting on each other. They liked using this outfit just as much as Aria's glue, so they decided to use both equally. But, they decided to sleep in this outfit every night, unless they didn't feel like it.
...
While Rarity and Aria slept together in their new outfit, Applejack and Adagio slept together in theirs. Sometimes they'd toss and turn trying to get to sleep, resulting in rubbing their butts together before they did. And Rarity let out a boisterous fart before she and Aria were asleep.
