Author's Notes:

Had to do a chapter for her. I might be a little meaner to her than the Rainbooms or the ponies, her being a villain and all. Again, scenarios might be too stretchy, maybe some OoC, maybe lower quality in the writing, but as usual, don't take it too seriously, enjoy it if you have the fetishes or just find it funny.

Aria was running through a dark forest. Rainbow Dash was chasing after her. Aria ran as fast as she could, but Rainbow Dash was faster. Rainbow Dash kicked Aria in the butt and Aria fell to the ground, her rear end in the air. Rainbow Dash spanked her again and again. Somehow it didn't hurt but it was humiliating all the same.

Then Aria had to pee badly. She stood up and ran, but Rainbow Dash gave her a wedgie and hung her up on a tree. Everyone at Canterlot High appeared and laughed at her. Aria was so embarrassed she wet herself right there. Then Rainbow Dash manifested her wings, flew up to Aria so that her butt was positioned in front of her face, and farted very loud for 10 seconds.

Then, Aria woke up. She looked around, and breathed a sigh of relief. This was just a nightmare about the humiliating event that had happened to her two days ago. Rainbow Dash hadn't done that to her again. She'd have no reason to as long as the sirens left the Rainbooms alone.

Aria's relief was short-lived, however. Her pants felt wet. She quickly sat up and removed the bed sheets. She was sitting in a puddle that smelled like pee. Aria couldn't believe it - she had wet the bed.

Aria sat frozen with fear for about five minutes, until she decided to get cleaned up and hope the other two sirens wouldn't notice. Before she could do anything, however, Sonata Dusk burst into the room.

"Rise and shine, Aria!" she said cheerfully.

Aria blushed beet red, accidentally farting loudly.

Sonata giggled, then looked at Aria's wet pants. Today she had gone to sleep in her usual outfit, and she had had another accident in her purple pants. Sonata started laughing hard.

"It's not funny!" said Aria. "You are absolutely the WORST!"

After Aria had showered and changed into a new pair of pants identical to her usual ones, Adagio Dazzle walked up to them and said "We're going camping now."

They packed up everything they were taking with them, and drove to a campsite, which was four hours away. Adagio was driving their car, while Aria and Sonata sat beside each other in the back seat.

"Can't we find a closer campsite?" said Sonata. "This ride is boring!"

"This is the campsite where we came across those three people we saw arguing really hard 20 years ago," said Adagio. "It gave us an unexpected meal and I have good memories of that place!"

"Can we at least listen to the radio?" said Sonata.

Adagio turned on the radio. They listened to some songs, and Adagio wished they could still sing like that, though the thought never crossed Sonata's mind, she just enjoyed the songs.

After about twenty minutes, Aria realized she hadn't used the bathroom before they'd left, and she had drank several cups of soda. She had forgotten they were going camping today, her embarrassing accident had driven it out of her mind. She was very uncomfortable now, and crossed her legs. She didn't want to wet herself twice in one day! Sonata would never let her forget it!

After about ten more minutes, they drove by a city.

"Can we stop at a gas station or something?" said Aria.

"We're not stopping for anything," said Adagio. "The drive is long enough."

Aria knew what she was about to say next would be risky, for fear that Sonata would make her have another accident, but she knew it was her best chance to find relief before she did without Sonata's help. "I have to go to the bathroom."

"You should have gone before we left," said Adagio.

"I'll always remember in the future, but can we please stop now?" pleaded Aria.

"Just hold it," said Adagio.

Sonata giggled. "I hope you don't end up peeing your pants again!"

Aria blushed.

...

While the sirens were on the road, Rainbow Dash and Pinkie Pie went to the fair again. This time they had a lot of fun, and rode the ferris wheel without a hitch. After which Pinkie pigged out on cotton candy.

...

It was two hours into the trip, and Aria really needed to go. She was holding herself and fidgeting non-stop. Sonata was no longer paying attention to the radio now, eagerly watching Aria and waiting for her to wet herself again. She considered startling Aria or tickling her, but decided against it because she didn't want Adagio to blame her for ruining the seat of her car.

Aria was in a lot of pain. She had to pee so badly, but Adagio wasn't stopping. She knew she wasn't going to hold it for another two hours.

"Adagio, can you pull over? I'll just pee at the side of the road!"

Sonata looked disappointed.

"I told you we're not stopping," said Adagio.

"But I don't think I'm gonna make it!"

"That's your problem, not mine."

Aria was really fidgeting now. The pressure in her bladder was extreme, and she'd be going for another two hours without relief. She knew beyond all doubt that she wasn't going to make it, but she held it in for as long as she could.

Then, ten minutes later, Aria felt her jeans grow warm and wet. Sonata could see her pants getting darker, and hear the hissing sound coming from her, and laughed her ass off. Aria was blushing profusely as she continued to soak herself and the seat of her car. Her panties were completely soaked, as were the crotch and butt of her purple pants. She hung her head in shame. She had wet herself like a little baby for the second time today. She was never going to live this down.

Adagio could hear the sound of Aria peeing herself, and could smell the scent of urine. "Aria, shame on you, peeing all over my car!"

"Only cause you wouldn't stop and let me use the bathroom," said Aria, still blushing as she finished peeing.

"We wouldn't be in this position if you'd used the bathroom before the trip," said Adagio. "Now you'll have to sit in your pee for two hours."

Aria let out a moan of shame and dismay.

...

Once they got home, Rainbow Dash and Pinkie Pie had another farting contest, which Rainbow Dash won. Her last fart was so loud and long that Pinkie Pie wet her shorts from laughing too hard. She blushed, but laughed it off and, without bothering to undress, took a bath with Rainbow Dash - a bath that was full of bubbles, without having to put any soap or mix in, to which Rainbow and Pinkie giggled.

...

The sirens arrived at the campsite. Aria was very uncomfortable for having to sit in her own pee for two hours, and smelled really bad. As soon as she was out of the car, she tried to find a spot where she could change, but Adagio stopped her and put her over her knee, not caring that her pants were getting slightly damp with Aria's pee.

"It'll be a long time before the car stops smelling like piss," said Adagio, and she slapped Aria's butt as hard as she could ten times, while Sonata laughed so hard she wet her panties, but it was so funny she didn't care!

Aria accidentally let out a wet fart, and Adagio spanked her one more time for farting on her. "Now, go and change."

Aria and Sonata changed into identical outfits to the ones they had peed in. Aria drank a big glass of water, and then helped Adagio and Sunset set up their tent.

While Sonata had fun at the campgrounds and Adagio reminisced about feeding off negative energy, something she could never do again, Aria sat on a log, feeling ashamed of wetting herself twice in one day.

After a few hours, Aria had to pee again, so she walked toward the outhouse. Just as she was reaching for the door, it opened, hitting her in the face. Aria fell on her butt, wetting her pants yet again while Sonata walked out.

"Sonata!" said Aria, blushing beet red.

Sonata giggled.

Aria pushed Sonata to the ground, sat on her face, and farted as loud as possible. Muffled screams came from under Aria's tush as Sonata flailed her arms and legs helplessly, but another long fart caused her to faint.

Aria managed to change into a dry pair of pants and panties without Adagio noticing that she had peed herself a third time. The rest of the day went better for her, and she had fun roasting marshmallows and telling campfire stories - until Sonata told a story about Aria wetting herself, causing Aria to slap Sonata's rear and remind her that she had also wet herself today, causing Sonata to blush and giggle nervously.

...

Sonata woke up the next morning. She looked to the side. Aria was still asleep, but she looked as though she was having another nightmare, likely about Rainbow Dash. As Aria tossed and turned, Sonata quietly undid her sleeping bag. Aria's purple pants were dry. Sonata was disappointed.

Then, a soft hissing sound could be heard. Sonata giggled to herself as a dark spot appeared on Aria's pants, which got bigger and began to get Aria's sleeping bag wet.

A few minutes after she stopped peeing, Aria woke up. "Oh no, not again!" she said in dismay as Sonata fell on her back kicking her legs in the air laughing. Her panties were visible but neither she nor Aria cared.

Aria was able to change into her last clean pair of pants before Adagio woke up. She drank a big water bottle before Adagio told them it was time to return home. Aria made sure to go to the bathroom before she got in the car. Aria sat in the same spot as last time, which was still slightly damp, stained, and smelled like pee, much to her embarrassment.

About an hour into the drive, Aria farted loudly. Sonata giggled, and Aria noticed that her window had been open the entire trip. She knew Sonata had to be behind this. Sonata was pleased with herself, having put fart powder in Aria's water bottle.

Aria let out a louder, longer fart.

PPPPFFFFFFFFRRRRRRRT!

She felt no shame about farting and didn't even blush, but Sonata laughed harder. Adagio could smell it even with Sonata's window opened, and opened her own window. "Phew, Aria, what did you eat?" said Adagio.

"Ask Sonata," said Aria as she let out an airy fart. "She put fart powder in my water."

"It was too funny to resist!" said Sonata, tears streaming down her face from laughing so hard.

Aria farted again, and again, and again, and Sonata laughed harder and harder.

"Be careful you don't have another accident," said Aria as she unabashedly let out a long wet fart.

FFFFFFFFFFFRRRRRRRRRRRRT!

Sonata laughed so hard she peed in her panties again, wetting the front and back of her skirt. She blushed, but when Aria farted again, Sonata just laughed some more.

"Damn it Sonata!" said Aria. "Remind me to spank you when we get home!"

Three hours into the trip, Aria had to pee, but nowhere near as badly as last time. She was very uncomfortable and crossing her legs by the time they reached the city. They stopped at a restaurant, as Adagio didn't feel like cooking today. As soon as they got their table, Aria ran to the bathroom. She was about to open the door, when it opened, and Rainbow Dash came out. Aria was so nervous she peed herself again.

Rainbow Dash chuckled, while Aria was too busy trembling with fear to even blush.

"So, come up with any more crummy revenge plans?" said Rainbow Dash.

"No," said Aria as she finished peeing. "No, I'm never gonna do anything like that again!"

"Good," said Rainbow Dash. Then, feeling a little bad for Aria, she said "You don't have to wet yourself every time you see me. I won't do anything to you as long as you don't do anything to us! And maybe I went a little extreme last time."

Aria relaxed, then looked down at her wet pants and blushed. Aria felt a much bigger fart coming than the ones before, so she unabashedly let it all out.

BBBBBBRRRRRRRRRRRAAAAAAAAAAAAAAAAAAP!

This fart was so loud and so wet that Aria made a mess in her pants. She blushed, and Rainbow Dash laughed.

Aria had to wear her wet and dirty pants until they got back to their house and she could change into one of her other outfits, while Adagio spanked Sonata for peeing all over the seat of her car.

Aria was much less fearful of Rainbow Dash now, and from that moment on, she never had another nightmare about Rainbow Dash again. She also never wet the bed again - except for the occasional time Sonata would put her hand in hot water while she slept, which would usually end with either Sonata's butt hurting, Sonata being unconscious from Aria farting while sitting on her face, or Sonata's panties being wet from being tickled too hard on her way to the bathroom, but Sonata didn't mind too much because she thought it was funny enough that it was worth it.
