Pinkie Pie and Fluttershy saw Rainbow Dash and Applejack walking ahead of them on the path, and caught up to them. Moments after, Sunset, Rarity, and the Twilights caught up to them and stopped running.

The girls walked along the path some more, and then they reached the edge of the forest.

"So, where is this dark crystal?" said Rarity.

"Sonata said there were signs leading to it... aha!" said Princess Twilight. "Follow the signs and we'll find it!"

"Unfortunately you'll never reach it!" came a voice. They turned to see the Dazzlings waiting patiently outside the forest.

"I think I just peed myself," said Princess Twilight.

Rainbow Dash had to pee really badly too, but she said nothing.

"RUN!" said Sunset.

The girls ran as fast as they could, but the sirens were catching up, for they were riding their chariot again, Fartsparkle pulling it.

"I'll hold them off!" said Rainbow Dash, and she turned around and ran at the wagon as hard as she could.

Rainbow Dash smacked into Fartsparkle and fell on her butt, wetting her shorts in the process. Fartsparkle reared back, stopping in place. Rainbow Dash hopped on Fartsparkle's back, still peeing, and rode her into a ditch. Then she jumped off and ran after her friends.

"YOU HAVEN'T SEEN THE LAST OF US!" yelled Aria. She climbed on Fartsparkle's back, who tried to pull the wagon out of the ditch.

...

Rainbow Dash caught up to the other girls.

"They're stuck in a ditch, so they're not going anywhere fast," she said.

"Still, we'd better not take any chances," said Twilight. "We have to run!"

They ran for a few minutes, following the signs, until they reached the dark crystal. Rainbow Dash picked up the crystal and kicked it toward a nearby rock wall. The crystal shattered to pieces.

The girls could feel their power return, and immediately ponied up, which magically cleaned them, much to their relief, especially Princess Twilight, Rainbow Dash, and Fluttershy.

After ponying down, they made their way back to the forest, until the sirens rode up to them.

"Uh-oh!" said Adagio. "They're sparkly clean!"

"How did they wash off so quickly?" said Sonata.

"Tranquilize them!" said Aria.

Adagio took out her tranquilizer gun, but EG Twilight telekinetically sent it flying out of her hand. Then she used her power to throw her into a nearby tree, knocking her out.

Rainbow Dash ran around Sonata, who began to get dizzy, and then Pinkie used her explosive power on her. Sonata fell to the ground, her leg twitching, and wetting her panties.

"No!" said Aria. "They have their powers back! Oh... I knew I should have used the bathroom before going on this trip!" She put both hands on her crotch, pulled out a paralysis dart, and fired at Rarity, who put up her barrier, blocking the dart.

Applejack grabbed Aria's arms from behind, while Rainbow Dash took her shoes off and lifted her legs in the air. Pinkie Pie tickled Aria's armpits while Princess Twilight tickled her feet.

"HAHAHAHAHAHAHA! STOP! I'M HAHAHAHAHAHA TICKLISH! HAHAHAHAHAHA!"

Pinkie and Twilight tickled harder.

"HAHAHAHAHAHAHA! STOP! HAHAHAHAHAHAHAHAHAHAHAHA! I'M GONNA PEE! HAHAHAHAHAHAHA!"

Pinkie and Twilight tickled even harder, and Aria wet her pants from laughing too hard.

"Now you know what it's like," said Sunset.

Applejack put Aria over her knee and spanked her ten times, causing greater pain than she could muster with each one because of her super strength, and then spun her around and threw her facedown.

"Fartsparkle!" said Fluttershy. The horse turned in her direction. "Sit on her."

Fartsparkle walked over to Aria and sat on her head. Muffled screams came from under Fartsparkle's butt as Aria flailed her legs helplessly. Aria let out a loud wet fart. Fartsparkle responded by farting even louder. Aria's muffled screams grew louder as her legs flailed more frantically. Fartsparkle farted again, and Aria made a mudslide in her pants. Rainbow Dash and Pinkie Pie giggled.

Fartsparkle farted on Aria one more time, even louder and wetter than before, and Aria's legs stopped flailing.

Fluttershy told Fartsparkle to stand up, and she did. Princess Twilight examined Aria.

"She's alive, but she'll smell like farts for a week."

"I don't smell like farts anymore!" said Rarity, greatly relieved at this.

"Let's go home now," said Sunset.

The girls returned home. Completely clean from their transformations, no one could ever tell the state they had been in, and they kept it between themselves. After a while, even Fluttershy got over it.

...

And from that day forward, Aria would always wake up in wet shorts, due to fear and possibly how hard Applejack had spanked her, for her butt didn't stop hurting until a few weeks after she stopped smelling like farts. Half the time she peed in her sleep, the other half she woke up in the middle of the night really needing to pee, but was too afraid to go to the bathroom on her own, held it in for an hour or two, and didn't make it.

One such night, Aria decided to get up, hoping that for once she could go the night without having an accident. She quietly tiptoed across the hall, looking around even though she didn't know what could realistically be going after her. She had to pee so badly and wanted to keep her pajama shorts dry.

Aria reached the bathroom door. She reached a trembling hand for the door handle.

Then, a creaky sound could be heard in the house. It was a sound that was heard all the time, but the slightest noise was too much for Aria. Aria screamed at the top of her lungs, farting loudly as she soaked her shorts. She ran back to her bedroom, jumped into bed, and hid under the covers, trembling and still peeing. She lay in her wet shorts for an hour before she fell asleep. She woke up in the morning to find a muddy mess in her shorts, again.

Meanwhile, Sonata had become leader of the Dazzlings and decided to stop trying to seek revenge.
