Author's Notes:

This chapter contains a bath scene.

It was nighttime, and the girls were at Pinkie Pie's house for their slumber party. They didn't have their pajamas with them, as they had spontaneously gone to Pinkie's house after the fair, but they felt they could sleep in their regular outfits this night, especially Rainbow Dash and Applejack. By now they had dried off from the Water Ride, although Rainbow Dash and Applejack still smelled bad.

Sunset's gassiness hasn't subsided yet, but Rarity kept the room smelling clean with her air freshener.

After a pillow fight and some ghost stories, they decided to do truth or dare.

"Ooh!" said Pinkie Pie. "Let me start!"

"Sure," said Twilight Sparkle.

"Applejack, truth or dare?"

"Dare."

"I dare you to press your face against Sunset's butt for a minute!"

Sunset giggled.

Applejack looked nervous. "Sunset, are you still..."

Sunset nodded.

Applejack gulped. Sunset got down on all fours, and Applejack put her face directly against her tush. She would have liked the feeling of Sunset's butt if her shorts didn't smell like farts.

Sunset let out several airy farts, and Applejack winced at each one, though she was sure the smell was easier for her to handle than it would be for some of the other girls.

After exactly one minute, Applejack finally backed away.

"Sorry about the farts," said Sunset. "I can't help being so gassy."

"That's all right sugarcube," said Applejack. "Your behind did feel kinda nice." She blushed lightly.

"Aw, thanks Applejack."

"Twilight, truth or dare?"

"Dare!" said Twilight excitedly.

"Ah dare you to sniff Rainbow Dash's armpit!"

Rainbow Dash chuckled.

Twilight felt nervous, but, Rainbow had to smell better than she did this morning after being soaked repeatedly in the Water Ride. She walked over to Rainbow Dash, who lifted her right arm. Twilight sniffed Rainbow's armpit, recoiled at the smell, and fell on her butt. The girls laughed.

"Rarity, truth or dare?" said Twilight, getting to her feet.

"Dare."

"I dare you to fart really loud!"

"Twilight!" Rarity blushed lightly.

"Or, I could change it to peeing in your dress again,"

"Fine. But... I don't really have to right now."

"I can fix that!" Pinkie left the room and returned with a container of fart powder. She sprinkled a bit of it into a glass of water and handed it to Rarity.

Rarity drank the water. It didn't have any taste, but knowing what was in it made her feel as though she drank something disgusting.

They waited a few minutes, and then...

FFFFFFFFFFFRRRRRRRRRRRRRRRT!

Rarity blushed beet red as this explosive fart blew her skirt back a little. Twilight giggled, while Rainbow Dash and Pinkie Pie started to laugh hard, Pinkie peeing herself again.

"Have you ever thought of wearing diapers?" Twilight asked Pinkie.

"No, I don't mind it like this. Besides, it's so much funnier if people can tell I wet myself." She giggled. "And you don't wear them when you study either."

"Right." Twilight also giggled a bit.

Rarity tried to look dignified. She was still gassy from the fart powder and tried to fart silently.

"Rainbow Dash, truth or dare?" said Rarity.

"Dare!" She hoped Rarity would dare her to fart, smell Sunset's farts, or pee herself.

"I dare you to take a bubble bath with soap, and scrub yourself everywhere for at least three seconds."

"Oh come on! I just washed, and I probably smell half as bad as I did before after that!"

"I'm sure you'll have your old smell back once you do some workouts and run some races without washing in between."

"Fine..."

The girls all followed Rainbow Dash to the bathroom. She filled the bathtub with soapy water and took her shoes and socks off.

"I don't have to take my shorts off, do I?" Rainbow blushed lightly at the thought that the girls might see her naked.

"No, you can wear them in the tub."

Rainbow climbed into the tub and sat down. She splashed herself with water, poured some of Pinkie's soap into her hands, rubbed them together, and scrubbed her armpits for three seconds, then her sides, then her back. She submerged her hair under the tub, as well as her top half so the soap didn't stay on her for long. She lathered her hair with shampoo, farting in the tub as she did so.

"Rainbow Dash!" said Rarity.

"You didn't say I couldn't fart in the tub!"

"I'll remember that next truth or dare." Ironically, Rarity accidentally farted loudly and blushed.

Rainbow Dash raised her legs, poured soap on them, and scrubbed them, along with her arms. She scrubbed her feet as well.

"There, now I just gotta rinse off."

"You're forgetting one thing."

Rainbow blushed lightly. "Do I have to?"

"It's part of the dare."

Rainbow got down on all fours, poured some soap on her butt, and scrubbed it with her hands for three seconds. The girls all giggled while Rainbow blushed. Then Rainbow stood up, drained the tub, and rinsed herself off with the shower head.

Rarity sniffed her. "A bit of your stench still lingers, but you're smelling much cleaner." She giggled.

"Don't rub it in," said Rainbow Dash.

"Yeah, you already did that enough with the soap!" Pinkie giggled at her joke as the girls walked back into the living room and sat down.

"I'll have to run several laps all day tomorrow," said Rainbow Dash. "So... Fluttershy, truth or dare?"

"Truth." Fluttershy didn't want to be dared to do something really uncomfortable.

"Do you think it's fun to fart?"

"Um..." Fluttershy blushed. "It would be really embarrassing to fart in front of anyone, even any of you, but... yes. I really like the relief."

"I'm sure we all do," said Sunset. "Even Rarity."

Rarity blushed, but admitted to herself Sunset was right, farting silently one more time before her gas was gone.

"Sunset, truth or dare?" said Fluttershy.

"Dare."

"I dare you to pee your pants."

"Wow, Fluttershy!"

"Oh. I'm sorry... I could change the dare if you want to..."

"No, I'll do it. I just didn't expect that from you."

"Well... You really seemed to enjoy it back at the fair, so I thought it wouldn't be too hard for you."

"Should I sit on a towel?"

"No, I'm used to cleaning this floor," said Pinkie.

While staying in her sitting position, Sunset started to pee even though she didn't have to go that badly. A soft hissing sound could be heard as she flooded her grey shorts for the second time in one day, and the carpet under her became wet. She couldn't help but sigh, more for liking the feeling of it than the relief.

"I don't blame you for liking it," said Wallflower.

"This probably won't be my last time, but I won't do it wherever and whenever like you do. Wallflower, truth or dare?"

"Dare."

"I dare you to pee in the toilet. Without getting your pants or underwear wet."

"Aw, I was looking forward to wetting myself tonight. I held it ever since the fair so the relief would feel better."

"You can do it tomorrow morning."

Wallflower walked into the bathroom.

"Um... do you mind if I close the door? My pants being dry should be proof enough."

"How will I know you didn't pee in your panties?"

"You can... um... feel my butt. If I wet my panties, it should be damp."

"All right."

Wallflower closed the bathroom door. They could hear the sound of her pee splashing into the toilet, and then a flush. Wallflower emerged from the bathroom, her jeans dry. Sunset felt her butt, and she couldn't pick up the slightest dampness.

"She's dry," said Sunset.

"Now..." said Wallflower. "Who hasn't gone?"

"Just me!" said Pinkie Pie.

"Pinkie Pie, truth or dare?"

"Dare!"

"I dare you to pee on me."

"I can't! I just went, remember?" Pinkie felt her wet shorts.

"Oh. Then... um... maybe drink a lot and then pee on me?"

"Okey dokey lokey!"

Pinkie walked to the kitchen, opened the fridge, and downed two large bottles of soda, spilling a bit down her front.

"That should do it!" BUUUUUUUUUUUURP!

Rarity looked annoyed while the other girls laughed.

They sat patiently while waiting for the drinks to go through Pinkie. They passed the time with a conversation.

Half an hour later, Pinkie was hit by a sudden urge and crossed her legs. "Ooh! I gotta go pee! REAL bad!"

Wallflower laid facedown on the ground. "Sit on me and then pee," she said.

Pinkie sat on Wallflower's butt.

"Do it," said Wallflower, extremely excited for this.

"I can't," said Pinkie.

"What?"

"I can't do it!"

"What do you mean you can't? You wet yourself the most out of anyone here except me!"

"I can only wet myself when laughing at farts! And the REALLY uncommon bedwetting, when I dream about farts. I don't know why but I can't do it under any other-"

BBBBBBBBBBRRRRRRRRRRRRAAAAAAAAAAAAP!

A wet fart made its way out of Sunset's rear, which was equally tremendous in volume and length. Rainbow Dash lifted her leg and let out an even louder fart.

Pinkie burst into a fit of uncontrollable laughter. And she burst in another way. Her jean shorts grew even wetter, and before long Wallflower's jeans were soaked. Wallflower let out a moan of pleasure.

"You girls are weird," said Rarity, but part of her found it all amusing. She also couldn't believe that one of her four friends who wet herself the most was also the only one who couldn't do so deliberately. Except maybe Fluttershy, who was another of the four.

"Truth or Dare is officially over!" said Twilight.

"Next time, can my dare not involve baths?" said Rainbow Dash.

"Very well, darling. I'll make you shower with soap next time." Rarity winked. "Now, Pinkie Pie, allow me to help you clean this carpet."

Once they finished having fun, they climbed into their sleeping bags. Pinkie, Sunset, and Wallflower still in their wet shorts/pants.
