"How long is the ride gonna take?" said Pinkie Pie. Her paralysis had worn off, allowing her to fidget where she sat. "I really need to pee!"

"You're gonna have to hold it!" said Aria.

"I'm serious! I really really REALLY have to go!"

"Just hold it or go in your shorts!"

Pinkie Pie crossed her legs and fidgeted harder. She became more uncomfortable as the journey went on.

"Don't even think of trying to pony up," said Aria. "After we lost our power, we traveled to Equestria to find new magic, and we found fragments of some sort of dark crystal. We brought it to Camp Everfree and combined it with some Equestrian magic that was there, and we created our very own dark crystal! We used it to block all your powers!"

"And you'll never find it across the forest next to our castle!" said Sonata. "Even with the signs pointing to it!"

"Sonata, you just told them where it was!"

"They'll never escape anyway, so it makes little difference," said Adagio.

"I have to pee so bad!" said Pinkie Pie. "Can't you pull down my shorts?"

"No," said Aria.

"If you don't, I'm gonna have an accident in your car!" She wasn't kidding. She was in desperate need of a bathroom, squirming even harder.

Aria put Pinkie over her knee and spanked her hard. She swatted her rear five times, and then firmly set her back into sitting position. Pain shot through her behind and she began peeing, soaking her jean shorts and forming a puddle where she sat.

"I told you she'd be the first," said Aria to Sonata, enjoying Pinkie's humiliation.

Pinkie blushed with embarrassment as she finished wetting herself. Her shorts were soaked and the smell of pee was in the air, though she did slightly enjoy the relief.

"Five more spankings for wetting your shorts!" said Aria, and she put Pinkie Pie over her knee again - after putting a garbage bag on her knee to protect her pants from the wetness - and spanked her five more times. Pinkie was rubbing her sore tush when it was over.
