A few days later, the sirens were plotting again.
"I wonder whether the stones can make people wet their pants," said Adagio.
"Let me test that," said Aria, and she pointed her stone at Sonata. Make her pee herself!
PPPPPPFFFFFFFFFFFFT!
Sonata giggled. "Nope!"
"If the stones affect the bowels, maybe they can make her mess herself," said Adagio.
Aria chuckled and pointed her stone at Sonata, who looked very nervous. Make her soil herself!
PPPBBBBBBBBBBRRRRRRRRT!
This fart sounded dirtier and wetter, but Sonata felt her butt and giggled. Aria lifted Sonata's skirt to inspect the damage, and was disappointed that there was none.
"So, they can only make people fart," said Adagio. "Hmmmm... I have an idea. But I'll need to stay here and think of a backup plan in case this fails. While I do that, Aria, make Rarity fart while she's hanging out with Rainbow Dash in the woods."
"Ooh, sounds evil," said Aria. "But why Rarity?"
"Because she played a part in our defeat as well, and she'd be the most embarrassed about farting."
"Gotchya!"
"And Sonata, fart in Sunset's face. But no longer than an hour!"
Sonata giggled. "That'll be fun!"
...
As Sonata was walking to Sunset's house, she ran into Pinkie Pie halfway there. Pinkie was wearing a white and pink T-shirt and short, tight jean shorts today.
Ooh! I can make another one of them fart and get revenge on her! Sonata raised her stone. Make her fart for an hour!
Pinkie let out a loud fart, and giggled.
Sonata squealed and ran over to her. "I think farts are funny too!"
Pinkie farted several more times. "Ooh, why am I farting so much?"
"I made you fart with this magic stone!"
"Ooh! We can have so much fun with this!"
"Wanna have a farting contest?"
Pinkie's eyes lit up. "Sounds like fun!"
Sonata immediately cast a fart spell on herself, and she and Pinkie took turns farting, each fart being loud and several seconds long. With each fart the other would laugh hard, accidentally farting a few times, but still have plenty of gas for their turn. Sometimes Sonata would stick her butt out to fart, and her skirt would be blown back by her farts so that her white panties could be seen, causing Pinkie to laugh more. Pinkie was in the lead halfway in after a boisterous 34-second fart that Sonata couldn't top. And after an hour, when they ran out of gas, Sonata cast the spell again!
...
Aria stood by Rarity's house and watched her leave. She followed her to the entrance to the woods, where she met with Rainbow Dash, and they walked in. Aria followed close behind, keeping as quiet as possible.
After a few minutes, Aria raised her stone and pointed it at Rarity. Make her fart now, and then for an hour!
Rainbow Dash turned around and saw Aria. "Rarity look out!"
As Aria shot her magic spell at Rarity, Rainbow Dash pushed her out of the way and was hit by the spell instead. Rainbow farted loudly.
"Shit!" said Aria.
Rainbow Dash and Rarity turned toward Aria.
"What are you doing here?" said Rainbow Dash. She felt a pressure in her bowels. "Oh no... Rarity, you might wanna keep a distance from me."
"Why..."
PPPPPPPFFFFFFFFFRRRRRRRRRT!
Rainbow chuckled. "Excuse me."
"Wait a minute," said Rarity. "That thing with Sunset, then you take a magic spell for me and now you're breaking wind suddenly... You did this, didn't you Aria?"
Aria turned around and ran, but Rainbow caught up to her and tackled her to the ground. Then she sat on Aria's face. Aria let out muffled cries. Rainbow's butt was a little sweaty and smelled slightly, but she knew it was about to get worse.
Rainbow looked up at Rarity, as if asking her approval.
"Oh, go ahead," said Rarity. "You just saved me, and this will teach that ruffian never to try this again."
Rainbow grinned and unleashed a flurry of loud farts on Aria. Many of these were long and/or wet. Aria thrashed her legs, screaming from under Rainbow's tush and trying her hardest to get out, but the farts made her feel nauseated, and she knew Rainbow would be farting for an hour. Eventually, Aria reached her limit, and everything went black.
"Is she all right?" said Rarity.
Rainbow got off Aria and saw her chest moving. "She's fine. She's just unconscious." Rainbow turned Aria over facedown, sat on her butt, and continued to fart on her.
...
Adagio was pacing back and forth. "Where are those two idiots?"
The door opened, and Aria walked in, looking weak and shaking slightly.
"What happened to you?" said Adagio. She walked up to Aria and sniffed. "Ugh, you smell horrible!"
"Rainbow Dash... took hit for Rarity... face-fart..." Aria shuddered.
"You need a bath." Adagio filled the tub with soapy water and threw Aria in fully clothed. As Adagio scrubbed Aria, Sonata ran into the room.
"Guys, the most amazing thing happened!" She noticed Aria, and quickly cast a spell on her. Bubbles appeared in the water around Aria, who blushed lightly but said nothing.
"Lol Aria farted in the tub!" said Sonata.
"So, how did your mission go?" said Adagio.
"It went great! I made Pinkie fart for revenge, but she thinks it's funny like I do, and we had a farting contest! She won, but it was the most fun I've had in EVER!"
"What?" said Adagio. "You were fraternizing with the enemy?"
"They're not that bad," said Sonata. "They forgave Sunset, why won't they forgive us?"
"Get out of here," said Adagio. "I don't want to see you in this house ever again!"
"But..."
"NOW!"
Sonata sighed, packed her things, and walked away.
Once Adagio washed the fart smell off Aria, Aria sat on her bed, still in her wet clothes, with her arms wrapped around her legs. She sat for hours before she eventually got over being farted on. But she didn't want that to ever happen again.
...
Pinkie was at home, enjoying the parting gift Sonata had given her after their farting contest. She had just let out a fart nearly as long as her winning fart in the contest when she heard the doorbell ring. Pinkie answered it. Sonata stood at the door.
"Ooh! Are we having another farting contest?"
"We could. Adagio kicked me out for betraying her."
"Aw, that's too bad. But no problem! You can stay here for now and help out around Sugarcube Corner!"
"Really? Thanks!"
Pinkie lifted her leg and farted loudly. Sonata cast a fart spell on herself...
