It was nighttime, a few days after the slumber party at Pinkie's house. Rarity changed into her pajamas, a light blue tank top and a short, tight pair of purple shorts with very soft fabric. Rarity climbed into her bed and laid down, trying to get to sleep.

But first, she let out a long, silent fart. She sighed in relief. She was dreadfully embarrassed about farting in front of the other girls at the slumber party, but she couldn't deny she loved the relief. Even when she was alone, she would always fart as silently as she could. It was the most ladylike way to do something... unladylike.

After one more silent fart, she fell asleep.

She dreamed that she was looking for a bathroom, but every time she found one, either the toilet would disappear or someone would walk in on her. Eventually, she found a bathroom with a shower. She sat on the toilet, but it disappeared, causing her to fall on her butt. So she walked into the shower, pulled the curtains back just in case, hiked up her skirt, and peed through her panties. She sighed in relief, and it felt so realistically warm.

Then Rainbow Dash and Pinkie Pie pulled back the curtains, saw what Rarity was doing, and started to laugh. Rarity blushed in embarrassment.

Then, she woke up. At first she felt relieved that the whole thing had just been a dream. Why would she pee in her panties anyway? Sometimes she did strange things in her dream she'd almost never do in real life.

The next thing she felt was that her pajama shorts were wet. She sat upright and pulled the sheets back. The sheets and mattress around her butt were wet. There was no mistaking it, she had wet the bed. She was so nervous she accidentally let out a loud fart. She didn't even bother to feel embarrassed about that. How could this happen to her?

...

Aria Blaze woke up, wearing her usual pajamas which consisted of purple shorts similar to Rarity's, and a matching midriff tank top.

Instinctively, she felt her shorts. They were wet. Aria moaned. More often than not she had wet the bed ever since Rainbow Dash had sat on her and farted on her.

She showered and changed into her white shirt, green vest, and purple jeans. When she was having breakfast with Adagio and Sonata, she spoke up.

"I know what I said before, but I suggest we get revenge on Rainbow Dash."

"Not interested," said Adagio. "She didn't do anything to us, and I have no desire for vengeance anymore." She had adjusted to living here by now.

"She's the reason I wet the bed every other day!" protested Aria.

"She's also friends with one of the funniest girls I know," said Sonata. "We have so much in common! I'd love to be friends with her!"

"What, the silly girl who also wets herself at the sound of farts? Yeah, I can see the resemblance. You should marry her and get the hell out of our house."

"Ooh! I have to go pee! I forgot to go when I got up this morning!" Sonata stood up.

Aria farted as loud as possible.

BBBBBBBBRRRRRRRT! PRRRRRRT! FFFFFRRRRPPP!

Sonata laughed so hard she peed in her dress. Aria smirked at the sight of her rival's pink skirt being soaked.

"No farting at the table," said Adagio. "Over my knee now."

Aria groaned and laid facedown over Adagio's knee. Adagio raised her hand and smacked Aria's rear. Aria winced at the pain, but did her best to keep quiet. Adagio spanked Aria ten times while Sonata giggled.

...

Rarity went to see the doctor, demanding that he keep it strictly confidential. The doctor returned with her tests.

"Miss Rarity, the tests show you are perfectly healthy."

"Then why is this happening?"

"My best guess is, it's just a part of you that has recently awakened. Did you drink anything before bed?"

"Only a cup of tea, a glass of water, and some apple juice."

"Did you use the bathroom before bed?"

"I didn't really have to go then."

"Then, it's likely it only happens when you have quite a bit to drink before bed, and don't use the bathroom in between. As long as you avoid that, you should be fine."

...

Aria was spying on Rainbow Dash as she was playing a soccer game with Indigo Zap, and Pinkie Pie at the sidelines cheering for Rainbow. Aria had the perfect plan to get even with Rainbow Dash, and hoped she wouldn't notice, or else she'd be in for another stinky punishment.

Once Aria was sure no one could see her, she slipped a mixture of laxatives and Sonata's fart powder into Rainbow Dash's current water bottle. She knew the game had just begun, and that the smelly girl had just run a race, and after this round she'd be hot and thirsty enough to drink the whole water bottle in one gulp.

She had just started to tiptoe away from the water bottle when Sonata surprised her.

"Hey Aria! Whatchya doing?"

"Sonata! You're gonna blow my cover! And you almost made me wet my pants!" She had spent so much time spying on Rainbow that she needed to pee.

"There's no shame in that!" Sonata pointed at her wet skirt, which she was still wearing. "What are you doing here?"

"Getting my revenge on Rainbow Dash! What are YOU doing here?"

"Trying to talk to Pinkie."

"Go ahead and be friends with her, see if I care."

Round 1 of the soccer game was over. Rainbow Dash wiped the sweat off her forehead with a towel, grabbed her water bottle, and downed it in seconds. Aria snickered. Indigo caught sight of this.

"Hey Pinkie Pie!" said Sonata, sitting down beside her. "I'm Sonata Dusk. I notice you find farts as funny as I do."

"Aren't they the most hilarious thing ever?" said Pinkie. She looked at Sonata's skirt. "Do you wet yourself from laughing at farts?"

"All the time." She giggled.

"So do I!"

As if on cue, the second round of the soccer game was beginning, and Rainbow Dash was letting out a series of wet farts. Pinkie and Sonata laughed, both girls wetting themselves.

Rainbow Dash of course wasn't one to let a few farts - or a lot - stop her from playing. But, before long, her farts became dirtier, wetter, and stinkier.

"Oh! I gotta go! Hold off about a minute!" Rainbow Dash ran behind a nearby bush.

Aria chuckled. Indigo looked suspiciously in her direction, and Aria started whistling. Indigo wasn't fooled. She walked over to Aria, looking angry.

"Did you do this?" said Indigo. "Did you interrupt our soccer game?"

Aria caught a whiff of Indigo. "Phew! You smell worse than her! Get away from me!"

"Did you?"

"Fine! I did! Just keep your stinky ass away from me!"

She said the wrong thing. Indigo grabbed Aria's face and forced it into her butt. Aria screamed and desperately tried to pull away. Indigo's butt and skintight shorts smelled like about a year's worth of sweat, farts, pee, and manure, and felt very dirty and slightly damp. After about seven seconds, Aria started resisting less, feeling nauseated, and her pants getting wetter by the second.

PPPPPPPPBBBBBBBBBBLLLLLLLLLLLLLLLLLLLRRRRRRRRRRRRRRRRRRT!

Indigo let out a long, boisterous, wet fart. Aria took one whiff and passed out. Still, she did not stop peeing.

Pinkie and Sonata laughed harder.

"I'm not done with you yet," said Indigo. She positioned herself above Aria's head and started to pee. Her stream passed through her filthy, foul-smelling shorts and onto Aria's head, waking her up and soaking her hair along with part of her shirt.

"Ugh... that was... Aah! What are you doing! Stop! Stop it!"

Aria tried to get up, but Indigo farted again, causing her to lay back down. Aria felt how wet her pants were and groaned.

Rainbow Dash came back. "Sorry about that. I really needed that, and I think my butt's as dirty as yours is now. I got my shorts down in time, but it was very wet." She saw what Indigo was doing. "Oh, is this girl up to her old tricks again?"

"You know her?" said Indigo.

"Yeah, she stole one of Twilight's inventions. I farted on her and I thought she'd leave us alone after that."

"She put laxatives in your water bottle."

"That explains it. I think I'm better now."

Once Indigo finished peeing, they continued playing the game, while Aria laid on the ground, wet, smelly, and humiliated.

Indigo won 7-6.

...

The next day, the girls went camping, including Sonata, who was wearing a short, skintight pair of pink shorts today.

As soon as they arrived, Fluttershy ran to the outhouse, but to her dismay it had an Out of Order sign on it. She walked back to the other girls.

"That was fast," said Rainbow Dash.

"Um... their outhouse is out of order."

"Then you can pee behind the bushes," said Applejack.

Fluttershy walked behind a bush, started to pull her panties down, but stopped and ran back to the girls.

"What if someone walks in on me and sees me peeing?"

"Would you rather pee yourself?" said Applejack.

"I'll hold it until the outhouse is fixed. Or until it's dark."

Aria snickered while watching from the bushes. Yesterday she had overheard Pinkie and Sonata discussing plans to camp here. So, she had arrived before they did and put the Out of Order sign on the outhouse. But, she realized it probably wouldn't impact Rainbow much. She didn't seem to mind going behind a bush. Aria continued to plot her revenge, trying to think of ways to sabotage Rainbow Dash or the entire camp.

The girls set up their tents. Rainbow Dash, Sunset, Pinkie Pie, and Sonata would be sleeping in one tent. Applejack, Fluttershy, and Wallflower would be sleeping in the second tent, and Rarity and Twilight would be sleeping in the third.

After a walk through the woods, they sat around a campfire having a conversation. Fluttershy fidgeting a bit, for she really needed to go.

"So, Sunset, how did it go with Flash Sentry?" said Twilight.

"It went well," said Sunset. "I wet my pajamas in front of him and he really liked it."

"That's wonderful," said Wallflower.

"But I'll probably only do that for him."

"Ahhhhhh," Wallflower sighed as she started peeing in her jeans.

Wallflower being Wallflower, Aria didn't notice.

But Rarity did. The sight and sounds made Rarity uncomfortable, for she was in need of a bathroom as well. She stood up and ran to the outhouse, but the sign was still up. So, she found a bush she was sure no one would look behind.

Back at the campfire, Sunset let out a silent fart. She was sitting beside Rainbow Dash, who could smell it. Rainbow Dash snickered and lifted both her legs.

BBBBBBBRRRRRRRRRRRRRT!

"Ahhhh."

Pinkie Pie and Sonata laughed hard, and before they knew it, their shorts were soaking wet.

Aria snickered at Sonata's accident. Except, Sonata didn't seem to mind. She must really be used to it.

Rarity returned, her skirt and panties dry. They resumed their conversation, but only ten minutes later, Fluttershy couldn't hold it any longer. Everyone could hear a soft hissing sound coming from her as she peed in her dress. She blushed lightly, but didn't feel as embarrassed about it in front of her friends.

"Feel better, sugarcube?" Applejack said.

Fluttershy nodded. The relief did feel nice.

It suddenly occurred to Aria what she could do. She'd make Rainbow Dash wet the bed by sticking her hand in hot water. It was the perfect plan. Rainbow Dash made her do the same, after all. She was feeling a need to pee now, so she stepped into the outhouse, being the only one who knew it really wasn't out of order.

...

After dinner - Rainbow Dash had beans again - it was nighttime, and after roasting marshmallows and telling campfire stories, Applejack took out several bottles of cider and offered them to her friends.

Aria continued to spy on them, waiting for the girls to go to sleep so she could exact her revenge.

"Oh, no thanks," said Rarity. "Half a bottle of water was quite enough."

"What's wrong Rarity?" said Applejack. "You've never turned down a bottle of mah cider before."

"I... I'm not really thirsty."

"That's not it. What's goin' on?"

"Well... Just recently I... wet the bed whenever I have a few drinks at night." She blushed. "I hope you don't find me disgusting."

"Rarity, none of us are in a position to find you disgusting for that!" said Rainbow Dash. "Look at Pinkie, Sonata, Fluttershy, and Wallflower!"

"You do make a good point. But it's still very undignified and unladylike."

"But you can still find it enjoyable," said Sunset. "Like I do with Flash Sentry."

"And when I'm studying," said Twilight.

"Doesn't the warm wetness feel nice?" said Wallflower. "I mean, if you're anywhere else, by all means avoid it if you can. But you don't have to feel ashamed if it's just us, or if you're on your own. Several times when I wake up, I just like to let it all out in my pajamas. It feels really good."

"And I did kind of enjoy sleeping in my wet pajamas at Flash's house," said Sunset.

"I did that once with Cherry," said Rainbow Dash. "Well, with the shorts I always wear, but they're basically my pajamas too."

Rarity had never thought about it that way before.

Neither had Aria. She was very curious about this. Could wetting herself actually be fun? She did notice that Fluttershy had gotten over her accident rather quickly and had as much fun as her friends. Fluttershy should have been a lot more embarrassed about it.

"You don't have to drink an extra bottle of cider if you don't want to," said Applejack. "But, if you do, and end up wettin' yourself, we won't think you're disgustin' or unladylike in any way. It did feel kinda nice back at the fair, and ah know you love this cider. It's your choice."

Rarity hesitated, and then took the bottle of cider and started drinking it, enjoying the refreshing taste.

Aria was even more intrigued now. The prissy lady was willing to risk wetting herself and could possibly learn to enjoy it. To her, wetting oneself had always seemed disgusting or undignified, but could it really be enjoyable? She'd have to experiment with that tonight before she made her final decision about getting revenge. She chugged down four cans of soda, belched loudly, changed into her pajamas, and climbed into her sleeping bag in her tent. If she still found this as unpleasant as every time since last summer, she'd make the smelly girl suffer.

...

Aria awoke to the sound of the rooster. She felt her pajama shorts. They were very wet. She remembered what the girls had said, and tried looking at it another way. Now that she thought about it, a part of her did like how it felt. It wasn't as warm, because she had woken up some time after peeing, but she did like the wetness and the smell. She also felt a sort of naughty pleasure, and actually giggled a bit.

She laid in her wet sleeping bag for about half an hour before she got out of bed. She walked to the outhouse and removed the Out of Order sign, throwing it in the trash. She had just turned around when Rarity came into view. Her pajama shorts were also wet, but she didn't seem to mind.

Rarity blushed at the sight of Aria, but looked at Aria's shorts and the red began to vanish from her face.

"Did you..."

"Yeah. I've been doing it since last summer, but I think it's kind of fun now."

"I know what you mean. I only just started recently, but my friends convinced me it could be rather enjoyable. Besides, I can avoid it whenever so by having less to drink at night."

"I can't avoid it to save my life. These shorts have been peed in hundreds of times."

Rarity giggled. "Well, at least you can look on the bright side now."

"If you wet your sleeping bag, why are you going at the outhouse?"

"Trying to see if it's working again so I can keep my dress dry without going behind a bush."

"Well, it looks like it is."

"I can see that."

"Before we go back to camp... You should know, I wasn't exactly the nicest girl. I was banished from Equestria by Princess Twilight, and tried to get revenge on your Twilight, but Rainbow Dash farted on me. That's why I wet the bed now. So, I tried seeking revenge on her with a laxative prank, but Indigo Zap farted on me."

"Oh, you poor thing! I mean... You did have it coming, but... she smells dreadful!"

"Yeah, I know I had it coming. And, I'd really prefer for it to not come again. And, now that I like wetting the bed, I no longer have reason for vengeance. So... Do you think you can forgive me and let me be friends with her now?"

"If you promise not to tell anyone outside of this camp that I enjoy wetting myself."

"I promise. If I betray you, you can tie me up for a week with no bathroom breaks and have Rainbow Dash fart on me and force me to smell her butt all she wants. AND Indigo."

"Then of course, darling."

Aria gave Rarity a hug. Then they walked back to camp. The other girls were awake.

Rainbow Dash looked a bit tense when she saw Aria at Rarity's side. "If you even try anything-"

"She told me what she did, and I assure you, she's learned her lesson," said Rarity.

"At the soccer game I wanted revenge on you because your farting on me made me wet the bed," said Aria. "But, seeing some of you wet yourselves without even batting an eye and talk about it being fun made me realize it didn't have to be something to seek revenge for. So... Will you accept my apology and my friendship?"

"Well... Sure." Rainbow Dash shook Aria's hand.

"Ooh, does this mean you're one of us now?" said Sonata.

"Maybe I was a little too hard on you," said Aria. "Sorry about farting as loud as I could every other time you had to go to the bathroom."

"It's all right! I don't mind! It was really funny, and I think it's even funnier when I wet myself!"

"Right."
