I Can't Undress!

The next morning, Sunset awoke. She felt her usual urge to pee every time she woke up, and hoped that the curse from yesterday had been a dream. She suspected it hadn't been, given that she was wearing her white and pink T-shirt - which were damp - and not her pajamas. She tried to pull her jeans down, but after seeing the zipper had broken off, she was not surprised that they wouldn't go down.

Rainbow woke up. "Oh, I really need to pee!" She ran to the bathroom and tried to pull her shorts down. "Oh, right." She sat on the toilet and peed in her damp shorts. She sighed in relief as she could hear the pee pass through the butt of her shorts and splash into the toilet below.

Sunset walked to the bathroom door and saw Rainbow Dash shamelessly peeing herself. "Well, I might as well..." She walked into the bathtub and peed in her jeans, again.

Rarity woke up. "Oh, PLEASE tell me that was just a dream..." She got up and tried pulling down her shorts. "Of course it wasn't."

She held it in for the next hour, but when the pressure got too intense, she let it all out.

"We really need to break this spell," said Rarity once she finished peeing.

"Let's try ponying up!" said Rainbow Dash. "It worked the last time we fought the sirens!"

They sang one of their songs, as if it was a performance for a big crowd on a stage. Their pony ears, ponytails, and, in Rainbow's case, wings appeared. Once they finished and they returned to normal, they tried to pull their pants down.

It still wouldn't work.

"Oh come on!" said Rainbow Dash.

"Well, let's shower so we stop smelling like pee," said Sunset. "Then let's have breakfast and think of a plan."

After their shower, they ate some hot dogs and drank some milk which tasted funny (Rainbow had zipped over to the convenience store and bought it), and also ate some scrambled eggs that Rarity, too distracted with her fear of wetting herself for the rest of her days, had undercooked.

Rainbow chugged down one soda after another.

"Rainbow Dash, you're going to wet yourself again within the hour," said Rarity.

"So? I kinda like it."

"Well I don't, and we need to find a way to break this spell."

"Maybe we should get Applejack to try to pull them down with her super strength."

"No, that won't work when they're magically cursed to stay on."

"Maybe Twilight can find a way to break the spell," said Sunset. "Maybe we could go to Equestria and get Twilight to perform a counterspell. No, wait... Our outfits might disappear if we do that, then Twilight won't be able to break a curse on them."

"But that in itself might break the spell," said Rarity. "Let's try it."

Rainbow Dash grabbed their arms and ran at full speed to the mirror at Canterlot High, and they went through the portal. They emerged in a castle as ponies. Rainbow and Rarity felt a bit weird that they weren't wearing anything, but this was normal for ponies. They had trouble keeping their balance, so they got on all fours, and jumped back through the portal.

"Now let's see if that did it," said Rainbow Dash, and she grabbed her shorts to pull them down.

"Rainbow, have you no shame?" said Rarity. "Not out here!"

"No one would be able to see her underwear under her skirt," Sunset pointed out.

"It doesn't matter," said Rainbow. "It STILL doesn't work!"

All of a sudden, a very uncomfortable feeling hit the girls.

"Uh-oh... I gotta take a dump!" said Rainbow.

"Me too," said Sunset.

"Me three," said Rarity, blushing a little.

Rainbow lifted her leg and farted loudly. She laughed despite her discomfort. "Hey, we might as well ease the pressure!"

Sunset let out a loud fart that smelled worse than Rainbow's. She blushed lightly. "Excuse me... That wasn't very ladylike, and my farts smell really bad because I'm a pony."

"Ugh, you're not kidding," said Rarity. "But as badly as I need to go, I am above such-"

FFFFFFFFFRRRRRRRRT!

Rarity blushed beet red as she let out a wet fart that lasted five seconds.

"We all fart, so there's no need to feel ashamed." Rainbow let out a boisterous wet fart.

BBBBBBBRRRRRRRRRRRT!

"Yes, but ladies are supposed to do it silently, and when no one's close enough to-"

PPPPPPPFFFFFFFFT!

"Normally I'm with Rarity, but in this case..." Sunset bent over.

BBBBBRRRRRRAAAAAAAAAP!

Rainbow laughed. "We should totally have a farting contest!"

"Ugh, first a holding contest now a farting contest?" said Rarity. "You're disgusting." Ironically, a sloppy wet fart made its way out of her rear right then. She put her hands on her butt, afraid she might have made a mess in her shorts. It was hard to tell because they were wet.

"Lighten up Rarity," said Sunset, farting loudly again. "She has every right to want to make light of the situation." She farted deeper and wetter than last time. "But... we should probably get back to the house. I don't want anyone else to be around when we do more than just fart."

Rainbow stopped laughing, as the realization slowly sunk in.

"You don't think... no... we're not gonna..."

"Oh, wetting myself is starting to look really good," said Rarity. "It's revolting and unladylike, but it's a lot cleaner than... soiling myself."

Rainbow quickly whisked Sunset and Rarity to Rarity's house. As she let go of them, she released a boisterous wet fart that was louder than any of her other farts today and lasted seven seconds.

"Oops... I might have farted too hard." She felt her butt. Her shorts felt dirty, but there was no mess in them... yet.

"Uhhhh..." Rarity released a flurry of wet farts, each one wetter and louder than the last.

And then...

PPPPPPPBBBBLLLLLSSSSSSHHHH!

Rarity blushed beet red. "I just soiled myself..." She felt her butt, and cringed at the wet, squishy feeling as a smell worse than Sunset's farts entered her nose.

Rainbow looked at Rarity's butt. There was a big brown bulge in her shorts. "Heheheh... You sure did!"

"You won't be laughing when you soil yourself."

"I think it's just gas for me." Rainbow lifted her leg and farted for seven seconds. Then a nine-second fart. Then 12 seconds, which turned VERY wet for the last five. "Oops... I just made a mess in my shorts." She felt her butt, and sat down, laughing at the sensation as she then peed herself.

"Ugh, you can't possibly be enjoying this," said Rarity.

"Try sitting down. It'll make it more comfortable when you stand up, and squish most of the mess through your shorts so it'll be less like you messed yourself and more like you sat in a mud puddle, which I do all the time!" She farted loudly. "And the mud I'm sitting in just got bigger!"

Rarity wrinkled her nose, but sat down. She hated to admit it to herself but she liked the feeling of her mess squishing under her rear.

Sunset, meanwhile kept farting, and then she felt an intense pressure in her bowels that she knew wasn't a fart. She tried pulling her pants down, but it was still no use. So, she sighed and noisily released the contents of her bowels into her jeans and underwear, staining them brown at the butt. Reluctantly, she sat down, and, like Rarity, she did seem to like the squishy sensation against her will.

"We should really shower now," said Rarity as she let out another fart. "Extra soap."

"Wait..." Rainbow clenched her eyes shut, then sighed in relief as the stench intensified. "Ahhhh, that's better."

"Why are we so gassy, anyway?" said Sunset. She sharted loudly and blushed a little more. "And why are we... pooping so messily?"

Rainbow stood up and waddled over to the empty carton of milk on the counter. "Oops... I might have forgot to check the expiration date on the milk." She let out another sloppy wet fart - and something else equally wet and sloppy - and laughed, for she drank twice as much milk as them. By now a mudslide was starting to ooze through her skintight shorts and down the back of her legs.

Rarity sighed, sharting twice.

They took a VERY long, soapy shower. By the time it was done they no longer smelled, but Sunset's pants, Rarity's shorts, and Rainbow's skirt were stained brown at the butt. Of course Rainbow's shorts weren't stained because they were black.

"At least we'll be able to clean up," said Rainbow Dash.

"Yeah, but if we have to go at school, it's over," said Sunset.

Rarity moaned, wetting herself a little.
