Author's Notes:

Another fetish story! Try not to take it too seriously, for OoC or stretchy scenarios. I'll write as OoC and stretchy as I want as long as fetishes are satisfied, and I'll do it to my heart's content!

Pinkie Pie and Rainbow Dash were sitting in Pinkie Pie’s house drinking lots of soda that Pinkie had put fart powder in. They both thought it was fun to fart and had decided to have a farting contest. Rainbow Dash was wearing her usual outfit, a dark pink skirt with skintight black shorts underneath, and Pinkie Pie was wearing her jean shorts as seen in Legend of Everfree.

After a few minutes, they began to feel the effects of the fart powder.

“Me first!” said Pinkie Pie. She lifted her leg and farted loudly. It only lasted two seconds.

“That’s a good start, but let me show you how it’s done.” Rainbow Dash farted for four seconds.

Pinkie Pie giggled. “That was just my warmup. Now I’ll get serious!” She let out a high-pitched fart for five seconds.

Rainbow Dash chuckled a little. “Not bad Pinkie! See if you can top this!” She lifted her leg and farted deeper-pitched for eight seconds.

Pinkie giggled. “Good one, Dashie! Let’s see if I can do better!” She turned around so her butt was facing Rainbow Dash, and farted as loud as possible. This fart was very wet and lasted seven seconds.

“I’m still winning,” said Rainbow Dash. She turned around, stuck her behind in the air, and let out a boisterous fart that was 12 seconds long.

PPPPPPPFFFFFFFFFFFFFFRRRRRRT!

“Wow, I don’t think I can beat that,” said Pinkie. “But I’m still gonna try!” She strained as hard as she could.

FFFFFFFFFFFRRRRRRRRRRT!

Pinkie farted for 10 seconds. As usual, this fart was high-pitched and wet, and made Rainbow Dash laugh.

“You win again,” said Pinkie Pie, not looking the slightest bit disappointed, for she did have fun. She slapped Rainbow's butt lightly.

“Awesome!” said Rainbow Dash. She took great pride in her ability to fart as loud and long as she did.

“Hey, the fair’s open today,” said Pinkie. “Why don’t we go?”

“Sounds good,” said Rainbow Dash.

...

At the fair, Rarity was walking out of the mirror house with Fluttershy. Rarity was wearing her usual purple skirt, while Fluttershy was wearing a white tank top and a pair of skintight green mini shorts, for it was a hot day. Fluttershy was drinking a big smoothie to cool down, when Aria Blaze stepped out in front of them, wearing her usual purple jeans.

“Why, if it isn’t my old enemies,” said Aria.

Fluttershy was so nervous she accidentally let out an airy fart. Aria didn’t hear it. Rarity did, but she didn’t say anything.

Fluttershy and Rarity braced themselves for a confrontation with Aria, but Aria simply walked past them. There was a brief moment of relief, and then Aria kicked Fluttershy in the butt as hard as she could. Fluttershy fell on her knees, her rear end in the air. Aria grabbed a ping pong racket and started smacking Fluttershy’s behind as hard as she could.

“Stop that at once, you ruffian!” said Rarity.

Aria put the racket back in its place. “I might as well. I have worse plans in store for you! But first...” Aria walked over to Rarity and let out a loud fart.

PPPPFFFFFFT!

Aria gave Rarity a smug look as Rarity started coughing from the stench. Aria walked away.

“Fluttershy, darling, are you all right?” said Rarity.

“I’m fine,” said Fluttershy. “But my rear hurts, a lot. Can you rub it for me?”

“Of course,” said Rarity. She put her hands on Fluttershy’s tush and started massaging it. Fluttershy’s butt was so soft, and Rarity loved the feeling of it. Fluttershy hoped she wouldn’t accidentally fart in Rarity’s face, but she didn’t.

“That’s much better,” said Fluttershy after about a minute.

“If I get the chance, I’ll show that Aria Blaze!” said Rarity.

They walked around for a bit, looking at all the attractions, before running into Rainbow Dash and Pinkie Pie. The four girls explored the fair together, until they walked up to the ferris wheel.

“That looks fun,” said Rainbow Dash. “Wanna go for a ride?”

“Sure,” said Rarity.

“I don’t know,” said Fluttershy. “It is awfully high...”

“Don’t worry,” said Rainbow Dash. “I’ll be with you, and you can be in the middle! Pinkie Pie?”

“I’d love to, but I wanna go get some more cotton candy first,” said Pinkie.

Pinkie Pie walked toward the cotton candy section while Rainbow Dash, Rarity, and Fluttershy got on the ferris wheel. Fluttershy sat between Rainbow Dash and Rarity.

...

Pinkie Pie finished wolfing down her fifth stick of cotton candy. Then, she saw a trail of marshmallows on the ground. She followed the trail, picking the marshmallows up and eating them. The trail led behind the haunted house, to a bench where usually no one sat. The last marshmallow was on the bench. As Pinkie threw it into her mouth, Aria suddenly grabbed her and put her over her lap, sitting down on the bench. Pinkie was so surprised she spit out her marshmallow.

“If it isn’t the most annoying Rainboom,” said Aria. “I thought Sonata was the worst, but you showed me I was wrong!” Aria raised her hand and swatted Pinkie Pie’s tush. Pinkie let out a squeal of pain. Aria smacked Pinkie’s rear again, and again, taking great pleasure out of this while Pinkie squirmed and tried to break free, but to no avail.

After 20 spankings, Aria stopped. Pinkie’s butt was in more pain than she had ever known, including that one time she had accidentally sat on a campfire. Then Aria reached down Pinkie’s shorts, grabbed her white panties, and gave her a wedgie. She hung her on a nearby tree branch. She hoped no one would find her here until her plan was complete.

“Get me down from here!” said Pinkie, blushing lightly because her underwear was visible.

“You’re staying here for a while,” said Aria, and she walked away.

“WAIT! ARIA! COME BACK! Ugh... I knew I should have used the bathroom before I went to the fair!” She crossed her legs and fidgeted where she hung.

...

“How are you doing, Fluttershy?” said Rarity as their seat on the ferris wheel was going up.

“It is kind of fun,” said Fluttershy. She leaned her head against Rarity.

“I hope this ride ends soon,” said Rainbow Dash. “I have to go, real bad!” Like Pinkie Pie, she had forgotten to go to the bathroom before coming here.

As they reached the highest position, the ferris wheel suddenly stopped.

"What's going on?" said Rainbow Dash and Fluttershy in terror.

Down below, Aria finished sabotaging the controls of the ferris wheel, and chuckled to herself. She knew it would take a while to fix it. She also knew from Adagio that Rainbow Dash had had a lot to drink earlier, Adagio having spied on them and called her. She'd stand by until it was done.

Rainbow Dash fidgeted where she sat. "Can they hurry it up? I really need to pee!"

Fluttershy and Rarity weren't feeling too good either. They weren't desperate like Rainbow Dash but they were uncomfortable. Then, Rarity accidentally farted loudly. She blushed, while Rainbow Dash chuckled, then shot her hand between her legs immediately as she felt a bit of pee leak into her underwear. She moaned in extreme discomfort.

...

"HELP! ANYBODY! GET ME DOWN FROM HERE!"

No one heard Pinkie's cries for help. She fidgeted hard, holding herself with both hands. Her underwear felt especially tight with the wedgie she was hanging from. She felt like she was about to burst!

Pinkie let out a squeal as she felt a jet of pee make its way into her underwear, dampening the crotch of her jean shorts. She managed to hold the rest of it in, at least for now, but she knew she was going to have a major accident if she didn't get down and find a bathroom fast.

Pinkie started fidgeting more, not only because she really needed to go, but also hoping it would break the tree branch so she would fall off.

"Aria, this isn't funny anymore!" said Pinkie. "I have to go pee!"

Of course, Aria couldn't even hear her, as she was patiently waiting for the ferris wheel to be fixed so she could see if she'd made Rainbow Dash pee herself, and even if she could hear, she wasn't going to help her now!

The pressure grew heavier and heavier. Pinkie closed her eyes tight. "Can't... hold on... any longer..." Pinkie immediately sighed in relief as her shorts grew warm and wet. The wetness soaked her panties and flowed down her legs, into her shoes. Some of the pee trickled down onto the grass below her. The release felt wonderful after holding it in for so long, despite her humiliation.

Pinkie peed for over a minute before she finally stopped. Her shorts were soaked and she was blushing lightly, but she still felt a sense of relief. Remembering she was still hanging from a tree by her underwear, which was mostly soaked now, Pinkie started moving around hoping the branch would break before anyone could see her like this.

...

Rainbow Dash fidgeted even harder, holding herself with both hands. She really needed to go, but it didn't look like they were moving anytime soon.

Fluttershy and Rarity needed to pee too, although not quite as badly as Rainbow Dash, both were fidgeting in extreme discomfort.

"Hurry it up!" said Rainbow Dash, feeling another spurt escape into her panties, dampening her shorts more. "I don't think I'm gonna make it!"

"You can make it, Dashie," said Fluttershy, trying to make her feel better, although she wasn't sure she herself was going to make it if they didn't fix the ferris wheel soon.

Rainbow wished with all her heart that she had used the bathroom before coming here. She had drank too much soda, and now she was paying the price. She squirmed even harder where she sat, in desperate need of a bathroom.

The pressure grew more and more, and Rainbow Dash couldn't hold it any longer. The floodgates opened, and Rainbow Dash began peeing where she sat. She blushed as her shorts became drenched, and soon the front of her skirt darkened. A puddle formed around Rainbow Dash's butt, but as the seat was slanted downwards slightly, the pee didn't reach Fluttershy, much to their relief. Instead it flowed over the edge, trickling down in front of the people below her, who began laughing.

"Ahhhhh, that's better," said Rainbow Dash. She felt ashamed beyond belief, but she felt immensely relieved after holding it in for so long, and she'd be lying if she said the warm wetness didn't feel a little good.

Fluttershy and Rarity could hear the hissing sound coming from her, and tried not to look in her direction. Then they heard the sound of Rainbow Dash's pee dripping over the edge of the seat, and Rainbow Dash's sigh of relief. This made them ten times more uncomfortable, and Rarity could feel her panties getting damp, but she was able to hold the rest of it in. They really needed to pee, but it didn't look like they were going to make it.

Rainbow Dash peed for over a minute just like Pinkie Pie, and stopped. She felt much better now physically, but was red in the face from absolute embarrassment. Her skintight shorts were completely soaked, as was the front and back of her skirt. The smell of urine was strong on her. There was no way Fluttershy and Rarity didn't notice this. She just giggled nervously.

"Oh, don't feel bad Dashie," said Fluttershy. "We still love you." She put her arm around Rainbow's back, but a jolt of pain from her own bladder made her shoot her hand between her legs. She had to pee so badly and the ferris wheel didn't show any signs of...

At that moment, it started moving again.

"Finally," said Rarity, who was really squirming where she sat.

Fluttershy on the other hand was startled, and could feel a few drops of pee shoot out into her panties, making a small damp spot on her shorts. She let out a squeak, but Rainbow Dash and Rarity were too distracted to notice.

As soon as they got off the ferris wheel, Rainbow Dash ran off in search of the nearby river where she could jump in and hide the fact that she had wet herself from anyone who hadn't seen it. Aria saw her and snickered to herself. Fluttershy and Rarity made a break for the nearest bathroom. Aria stuck out her leg and tripped Rarity, who fell flat on her face. For about a second, Aria could see Rarity's purple panties, which were damp. Aria sat firmly on Rarity's butt.

"Get off me!" said Rarity. "I need to use the bathroom!"

"This is exactly what I'm going for," said Aria. "So, I see Rainbow Dash didn't make it! My revenge is at hand!"

Rarity tried to force Aria off her, but Aria wouldn't budge. In her position Rarity couldn't even put her hands on her crotch, and she knew she was on the verge of wetting herself unless something unpredictable happened.

Then, Aria farted loudly. This fart was boisterous, wet, and lasted six seconds. This was too much for Rarity. She immediately blushed beet red as she began peeing, soaking her underwear and the front of her skirt. Aria could hear the sound of Rarity peeing, and saw the puddle form under her as she started laughing. "Score two for the sirens!"

Meanwhile, Fluttershy ran into the bathroom, but to her dismay all the stalls were full. Fluttershy held herself and did the pee-pee dance, knowing that if someone didn't get out soon, she was going to wet herself for the first time in six years.

Finally, a toilet flushed and a girl left the stall. Fluttershy immediately ran into the bathroom, but at that moment, she lost control. As Fluttershy began peeing herself, she quickly sat on the toilet to avoid making a puddle on the bathroom floor. She peed through her shorts into the toilet, and she could feel the warm wetness soaking her panties and spreading through the crotch and butt of her shorts.

This was the most embarrassing thing that had happened to Fluttershy in years, but she couldn't deny the release felt good, and couldn't help but sigh in relief. In the middle of peeing, she let out a wet fart, and giggled to herself, forgetting that the other girls in the stalls could hear.

Fluttershy peed for just over 30 seconds, while outside, Rarity peed for just under 30 seconds. When Rarity stopped peeing, she said "Aria Blaze, you are so uncouth!"

Aria saw Fluttershy exit the bathroom, trying hard not to be seen, as she made her way toward the river, having the same idea as Rainbow Dash. Aria could clearly see the wet spot on Fluttershy's shorts. "Aha! Fluttershy wet herself! Revenge is mine!" She remembered Pinkie Pie, so she got off Rarity and ran in the direction of the haunted house.

Rarity stood up and walked toward the river as well. She walked by a few people who noticed her wet skirt and started snickering. Rarity was so embarrassed she accidentally farted, but this fart was silent and didn't seem to smell. She ran up to the river, where she could see Fluttershy was taking a bath. She pretended to trip and fell in.

Fluttershy blushed. She had seen Rarity's skirt and knew that she had wet herself, but she didn't say anything. She didn't want Rarity to know that she had wet herself too, so she said "It was a hot day today. I needed to go for a swim."

"So did I," said Rarity. "I knew I should have worn my camping outfit on a hot day like today." She seemed a bit relieved. Fluttershy hadn't seemed to notice that she had wet herself, or maybe she did and wanted to stay quiet. Rarity knew Fluttershy had wet herself, but she wasn't going to say a word.

...

Aria walked up to Pinkie Pie, still hanging from a tree by her underwear, and her shorts soaked with urine. Aria broke the tree branch, and Pinkie Pie fell on her butt. She received a sharp jolt of pain, as her butt still hurt from Aria spanking her. She let out a moan of pain, wetting her shorts a little more.

"In your face!" said Aria. "My revenge is complete! I screwed up the ferris wheel that your friends got on, and I made all of them wet themselves too!"

"So it was you!" came a voice. Aria looked behind her to see Rainbow Dash, soaking wet, having followed her here.

"Rainbow Dash!" said Pinkie Pie. She was overjoyed to see her, though she blushed lightly at Rainbow Dash seeing her in her current state. Her underwear was still showing so she quickly moved it under her shorts, and giggled nervously.

"You screwed with the wrong girl!" said Rainbow Dash, and she sat on the bench and put Aria over her lap. Rainbow Dash slapped Aria's butt as hard as she could. Aria yelped in pain, but refused to let tears fall. After Rainbow had spanked Aria 10 times, Pinkie took off her shoe, which was wet and smelled of pee, and whacked Aria's tush with it 10 more times. Aria couldn't hold back her tears this time. Rainbow set Aria down on her knees, and Aria rubbed her butt.

Rainbow Dash noticed Aria put her hand on her crotch slightly, then move it away. Aria hadn't gone to the bathroom for hours and now she was feeling an urge to pee.

Rainbow Dash sat on Aria's butt, forcing her to the ground. "Pinkie, tickle her!"

Pinkie Pie took Aria's shoes and socks off and began tickling her feet with her fingers. Aria started laughing hard. She tried kicking her legs, but Rainbow Dash wouldn't let the top halves of her legs move.

Pinkie saw a feather laying on the ground. She picked it up with her left hand and tickled Aria's left foot while she continued to tickle her right foot with her hand.

"HAHAHAHAHAHA! STOP! HAHAHAHAHA! I'M REALLY HAHAHAHAHAHAHA TICKLISH! HAHAHAHAHAHA!"

"That's good to know," said Rainbow Dash, and she started tickling Aria's armpits.

Aria laughed even harder. "HAHAHAHAHAHA! STOP! HAHAHAHAHAHAHA! I'M GONNA PEE! HAHAHAHAHAHAHAHA!"

"That's what I'm going for," said Rainbow Dash, and she and Pinkie Pie tickled harder. Aria laughed even harder, and wet her pants. Rainbow Dash could hear the hissing sound emanating from her, and Pinkie could see the puddle forming under her. Still they kept tickling, and Aria kept laughing, blushing with the embarrassment of peeing her pants.

After Aria stopped peeing, Rainbow Dash and Pinkie Pie stopped tickling. Aria lay on the ground panting. Rainbow Dash stood up, positioned her butt next to Aria's face, and farted as loud as possible. This fart was deep-pitched and lasted seven seconds, and Rainbow Dash chuckled.

"Me next!" said Pinkie Pie. She stuck her rear end in Aria's face and let out a boisterous wet fart that lasted six seconds. Aria was coughing from the stench.

"Think she's had enough?" said Pinkie Pie.

"No way," said Rainbow Dash. "We want to let you know we can top any revenge plan you throw at us tenfold!"

"No, really, I've had enough," said Aria, red in the face and her eyes full of tears. Her purple jeans were soaked at the front.

"Not yet," said Rainbow Dash. She gave Aria a wedgie, lifting her off the ground, and hung her pink panties over her face. The back of her panties were fairly dry since she was facedown at the time of her accident and had mostly only soaked the front of them, but it didn't make her like this any better. Rainbow Dash forced Aria out from behind the haunted house and kicked her in the butt. Pain exploded through Aria's rear like she had never experienced, and she fell facedown on the ground.

"Now she's had enough," said Rainbow Dash. Pinkie Pie kicked her in the tush one more time and they walked away.

Aria lifted her panties off from her head, blushing profusely. She had never been so humiliated in her entire life. Her underwear was clearly visible, her pants were soaked with pee, and her butt was in a lot of pain. She tried to think of another plan for revenge, but realized that if she did, Rainbow Dash would do something even worse to her. She sighed, conceding defeat to Rainbow Dash.

...

While Rarity and Fluttershy continued to enjoy the fair, Rainbow Dash and Pinkie Pie returned to Pinkie's house.

"My butt still hurts," said Pinkie Pie. "Can you give me a butt massage?"

"Rarity's better at that than me, but sure." Rainbow Dash rubbed Pinkie Pie's butt, which started to feel better in seconds. Pinkie had neither changed nor washed, and her shorts were still damp and smelled of piss, but she didn't seem to mind now.

"We're still gonna do farting contests like that and ride the ferris wheel again, right?" said Pinkie Pie. She didn't want this experience to ruin any of that in the future.

"Of course!" said Rainbow Dash. "It's too fun not to! We'll just remember to use the bathroom before we go to the fair. And Aria isn't gonna try that ever again."

Pinkie let out a wet fart, and giggled.

...

Aria walked back into her house, trying to sneak into her room unseen, but Sonata Dusk jumped out.

"Hey Aria, what you doing?" said Sonata.

Aria was startled, peeing a little more. "Nothing," she said, blushing lightly.

"Haha, Aria wet herself!" said Sonata. "Don't worry! I'll start a bath for you!"

Sonata took Aria to the bathroom, put together a bubble bath, and threw her in without bothering to undress her first.

"I was hoping not to make such a big scene," said Aria.

"Aw, lighten up!" said Sonata. "I think it's really funny!"

"Did you think it was funny when you wet your pants a couple weeks ago?"

Sonata blushed. "Yes?" she said.

Aria farted in the tub. Sonata giggled, but Aria was in no mood.

"We're done trying to get revenge. Rainbow Dash did this to me, and she'll do far worse if I try anything again."
