Applejack hangs out with Rainbow Dash, who satisfies all her fetishes and loves it. Then two more ponies jump in.

Applejack takes Rainbow Dash to drink cider in celebration of winning a race against Lightning Dust, and becomes attracted to her with plenty of fetish fuel. And then things heat up when two more ponies want in on the action! Things get even more exciting for Rainbow Dash when Fluttershy reveals her deepest fetishes to her.

Basically, this combines all my fetishes into one story, with the pony I love to see them applied to the most: Rainbow Dash! Representing the one with the fetishes will be Applejack, since I previously had her as being into one of them. Thus, will contain some hints of AppleDash. In Chapter 2 will be the next two ponies I like to apply my fetishes to. Chapter 3 will involve Fluttershy (I initially intended not to use her, until I realized a lot of people actually like sex/fetish stories about her)

Contains: Sweat, butt rubbing, fart, Omorashi/wetting, a bit of olfactophilia, zero explicit content, and possible OoC/stretchy scenarios. Chapter 3 contains spanking and facesitting. So if you aren't into any of them, turn back, and if one is a real turn-off for you, you might not like this story. And try not to take it too seriously, this is just another fetish story written specifically for people with these fetishes. And don't expect too high quality, it's meant to be about average.

Although I am kind of into sweat, having put a few scenes of it in a previous story, I don't think that's exactly a fetish for me, but a story I read part of recently might have given me a fetish for olfactophilia, which I'm not sure about so that will probably be featured the least. This is the next level of my darkest fantasies unleashed, though I do not aim to be as infamous as some fetish writers are.

And one part will be recycled from one of the less detailed chapters of my first story, and will try for more detail. If you find the system too repetivive being used with three ponies, it's only so anyone who prefers one particular pony over the other two can fully enjoy it.

This story won't even try to act like it could ever happen, as I said unlikely scenarios and out of character moments, so again, please don't take it too seriously and if you like any of the fetishes, enjoy it for that, because that's what it's for.

Rainbow Fetish

Lightning Dust returned and challenged Rainbow Dash to a flying race a great distance, intending to prove herself the better flyer. Rainbow Dash accepted her challenge without a moment's hesitation. During the race, Rainbow Dash was wearing her Equestria Games outfit, a yellow tank top and skintight white shorts, and Lightning Dust wore a similar outfit, except her shirt was teal.

It was a close race, but Rainbow Dash won. The ponies at the finish line all cheered. Lightning Dust stormed off in a rage.

"Congratulations, Rainbow," said Applejack. Rainbow Dash was panting and sweaty, her outfit very damp. It was a hot summer day, after all. For some reason, Applejack really liked seeing Rainbow Dash like this, and the smell of the sweat on her. "Come with me to Sweet Apple Acres and I'll give you as much cider as you want."

Rainbow Dash followed Applejack to Sweet Apple Acres. Granny Smith and Big McIntosh were away on a trip, and Apple Bloom was hanging out with Sweetie Belle and Scootaloo. Applejack stacked up several barrels of cider, and Rainbow Dash poured several cups and drank them.

"Now, you up for a race around Sweet Apple Acres?" said Applejack. "Footrace. Five laps."

"You're on!" said Rainbow Dash.

"First let's do some situps," said Applejack.

Applejack and Rainbow Dash each did 15 situps. By the time it was over, Rainbow Dash was panting. Applejack gave her five more mugs of cider, and drank two herself. Then, Applejack drew a finish line at an area just outside Sweet Apple Acres.

"Now remember Rainbow Dash, don't use yer wings," said Applejack.

"I won't," said Rainbow Dash.

"Ready... set... go!" Rainbow Dash and Applejack ran as fast as they could. They were neck in neck for the whole race. After five laps, Rainbow Dash won by a nose. She and Applejack lay panting on the ground.

Applejack drank some more cider, then walked over to Rainbow Dash. Rainbow Dash was now dripping with sweat, her Equestria Games outfit completely soaked, and already a puddle of sweat was forming where she was sitting. She smelled strongly of sweat too, and Applejack liked it.

"Well, help yourself," said Applejack, pointing at the barrels of cider. As soon as Rainbow Dash caught her breath, she walked to the barrels of cider and started drinking them like there was no tomorrow.

Applejack couldn't help but stare at Rainbow Dash's butt. She had the cutest butt in all of Equestria.

Then, Rainbow Dash let out a loud, wet fart.

PPPPPFFFFFFRRRRRRT!

Rainbow Dash started laughing hard. She loved to fart, and she thought it was funny. Applejack didn't think it was funny, but something about seeing Rainbow Dash fart aroused her even more. Had she just discovered a new fetish?

"It's not funny, Rainbow Dash!" said Applejack, and before she could stop herself, she slapped Rainbow Dash's butt.

Rainbow stopped laughing. "Ow, that hurt!"

Applejack froze. She couldn't believe she had just spanked Rainbow Dash. She hoped the pegasus would forgive her.

"My butt needs a good massage to recover from that," said Rainbow Dash. "Do that and we'll call it even." She blushed lightly.

Applejack couldn't believe it. Rainbow Dash wanted her to rub her butt! Could she possibly feel the same way about her? Applejack put both her hooves on Rainbow's behind, and hesitated for a moment.

"Can you hurry it up?" said Rainbow Dash. Maybe this was a dead giveaway, but she couldn't help herself. She was really looking forward to this.

Applejack started caressing Rainbow's rear. Applejack loved the feeling of Rainbow's tush against her hooves. Her butt was soaked with sweat, but that only made it more enjoyable for Applejack.

Rainbow Dash enjoyed this just as much as Applejack. "Ahhh, that's it. Keep going."

After about 20 seconds, Rainbow Dash accidentally farted. She blushed lightly and giggled nervously. She felt no shame about farting, but this time she farted in Applejack's face and was worried that it would make Applejack stop.

Applejack could tell what Rainbow Dash was thinking. "Ah love it when you do that," she said, and she meant it.

"Oh, you do?" said Rainbow Dash, a grin spreading across her face. She raised her behind in the air, as Applejack continued to rub it.

PPPPPPPPPPPPPPFFFFFFFFFFFFTTTT!

The loudest, wettest fart yet made its way out of Dashie's butt, and lasted 10 seconds. It smelled really bad, but Applejack loved it, and started rubbing even harder. She didn't want Rainbow to tell her to stop. And Rainbow didn't want Applejack to stop.

Until about a minute later, when Rainbow felt a powerful urge to pee. She had drank more cider than she could count and it was starting to affect her. "STOP!" she said suddenly.

Applejack stopped. "Aw, did I do something wrong?" she said.

"No, I loved every second of it!" said Rainbow Dash. "But I have to pee really badly!" She had a pained expression on her face and her hooves were dancing in place. She was very uncomfortable, but had to take the few seconds to explain this to Applejack.

Rainbow Dash started to fly toward the bathroom, but stopped. She couldn't fly any farther. She turned around. Applejack was grabbing her tail with her teeth and pulling her back.

"Let me go!" said Rainbow Dash. "I REALLY need to go!"

Applejack's heart was racing. Her biggest fetish was for another mare to pee herself. Normally she'd never do this to anyone, but her other fetishes had just been satisfied and she could only think about making this one come true.

Rainbow Dash desperately tried pulling free of Applejack, but Applejack wouldn't budge. Rainbow Dash pulled harder. She really needed to go! She hadn't had to pee this badly since as long as she could remember! Her heart was also pounding, with the fear that she might not make it, even if she got free of Applejack.

Finally, Rainbow Dash could hold it in no longer. She let out a whimper as she peed in her already-wet shorts. Waterfalls of pee flowed down her legs and a puddle grew rapidly. Rainbow stood still, and Applejack released her, watching in amazement. Though she did feel a twinge of regret. This might have gone too far. She blushed beet red, both from witnessing Rainbow Dash satisfying her greatest fetish, and from shame at doing something like this to her.

Rainbow Dash also blushed, feeling ashamed beyond belief. She, Rainbow Dash, the fastest pegasus in Equestria, was wetting herself. Though now that she thought about it, she was already wet so this hardly mattered. But as she continued peeing, she realized how wonderful it felt to let go after having to pee so badly. And she also realized she actually enjoyed the feeling of peeing herself. All shame forgotten, she let out a sigh of immense satisfaction. Applejack began to relax at this. If Rainbow Dash was enjoying it, she didn't have to feel bad about it.

Rainbow Dash peed for just over a minute before she stopped, standing in a huge puddle. "Ahhh, that's better," she said.

"I'm sorry sugarcube," said Applejack. "Ah don't know what came over me."

"Don't be," said Rainbow Dash. "I really enjoyed it." She blushed lightly. She'd hate to admit this to anyone else, but she didn't want Applejack to feel bad over putting her through something that was fun for her.

"You mean it?" said Applejack.

"We should totally do it again," said Rainbow Dash.

"I'm looking forward to it," said Applejack.

"But first," said Rainbow Dash, "you didn't finish my butt massage."

Without a moment's hesitation, Applejack began rubbing Rainbow's butt again. Rainbow Dash smelled of sweat and urine, and Applejack loved it.

Two New Players

Applejack and Rainbow Dash met up at an empty field, Rainbow Dash wearing her sports outfit again.

"The usual?" said Rainbow Dash.

"Of course," said Applejack.

Applejack and Rainbow Dash raced around the field 10 times on foot. By the time they were done, both mares were dripping with sweat.

Applejack started rubbing Rainbow Dash's butt with her hooves. Rainbow Dash farted in Applejack's face three times, laughing at it while Applejack loved the fetish fuel. Then Rainbow Dash said she had to pee, and flew off, trying not to fly too fast. Applejack grabbed her tail and held her back. Rainbow held it in as long as she could, she thought it was more fun this way, and then wet herself, sighing in relief.

Then Pinkie Pie jumped out from a nearby bush and started laughing. "This is the funniest thing I've ever seen!"

"Pinkie Pie!" said Rainbow Dash, blushing beet red, as she was still peeing. "What are you doing here?"

"I was going for a random walk, when I suddenly heard someone farting in the distance. Farts are funny so I ran over to see who it was, and then I saw you two!"

"How much did you see?" said Rainbow Dash, who had finished peeing at that point but was sure Pinkie had seen it.

"All of it!" said Pinkie Pie. "And I think it looks really fun! Do me next!"

"Wait, what?" said Rainbow Dash.

Pinkie put on her exercise outfit, which she apparently got from nowhere, consisting of a yellow shirt and skintight teal shorts. She took out a huge barrel of soda, sprinkled something into it, and drank 20 glasses of it. Rainbow Dash didn't know where the hell she got it, but it hardly mattered to her.

"Time to race! 1 2 3 go!" She ran around the track. Applejack and Rainbow Dash ran too, both tired from the previous race. In the time it took them to run five laps, Pinkie ran 25. "Okay, we're done!" They stopped, panting, and all dripping with sweat. Applejack was right next to Rainbow Dash, who smelled of sweat and pee, but she hardly noticed, since the opportunity to apply her fetishes to another mare had presented itself.

"Well, what are you waiting for, Applejack?" said Pinkie Pie as she turned around so her rear was facing Applejack, farting loudly. Rainbow Dash laughed at this.

"All right, if you say so," said Applejack, and she began rubbing Pinkie Pie's tush. Pinkie let out a long, wet, high-pitched fart, giggling the whole time.

Rainbow couldn't help but stare. She now understood why Applejack liked this so much. Did she have a fetish for this too? Well, she didn't have a fart fetish. She just thought it was funny. She chuckled a little as she let out an airy fart.

"Hoo, what in tarnation did you eat?" said Applejack as Pinkie farted for the sixth time, just as long and loud as the previous five farts.

"I put fart powder in that soda I drank," said Pinkie. "I keep containers of fart powder stashed all over Equestria in the case of fart powder emergency."

"Uh, if you say so," said Applejack, but she was enjoying this too much to be weirded out.

Then Pinkie felt the full effects of the soda hit her. "Stop! I have to go pee!" she said. She sighed in relief as she let it all out in her skintight shorts, the pee flowing down her legs and onto the grass.

"That's not how it goes!" said Rainbow Dash. "You're supposed to make a run for the bathroom, and then Applejack pulls you back!"

"It's all right," said Applejack, who was still enjoying this. "She can do it how she wants."

Rarity walked in to see Pinkie finish peeing herself, slap her behind with her front hoof, and Applejack to start rubbing it again. And then Pinkie farted again.

"Ugh, what in Equestria are you doing?" said the prissy unicorn.

"Hi Rarity," said Pinkie unabashedly. "We're having a lot of fun! You should join us!"

"You think wetting yourself, breaking wind, and having your butt rubbed is fun?" said Rarity. "How uncouth!"

"C'mon, Rarity, try it," said Applejack.

"Never," said Rarity.

"It's more fun than it looks at first," said Rainbow Dash, blushing lightly. Rarity saw her shorts were yellow at the front for the first time.

"Well I'm not going to," said Rarity. "Unless..."

"Unless what?" said Applejack, who stopped rubbing Pinkie's butt, much to Pinkie's disappointment.

"Unless you beat me in a race," said Rarity, blushing lightly.

Applejack's heart started beating fast. Rarity had not, to the extent of her knowledge, even run a race before, while Applejack was one of the fastest runners. Why would Rarity challenge Applejack to a race she knew she would lose unless...

Rarity hoped this wouldn't be too obvious. She was curious about what all of it would be like. Of course, it wasn't as though she hadn't farted before, but she'd only do it when no one else was around.

"You're on!" said Applejack.

"Let me change into racing attire," said Rarity. Applejack smirked as Rarity ran off. She'd run both races without wearing anything, and so had Rainbow Dash and Twilight, once. She knew what Rarity was up to, and she wouldn't say a word, for fear that Rarity would back out of it.

Rarity returned wearing a light blue shirt and skintight pink shorts. By now Applejack had had time to relax. It was essential that she win this race. Rarity drank 10 mugs of Pinkie's soda. Pinkie and Rainbow Dash giggled, knowing they were about to see the ladylike unicorn do something very unladylike.

"First to five laps wins! Now... go!" Applejack and Rarity ran around the racetrack. Applejack ran as fast as she could, and so did Rarity, who wanted to make it seem as though she wanted to win. At her fastest, she couldn't catch up to the farm pony.

When Rarity reached the finish line after the fifth lap, Applejack was already there. Rarity panted, completely soaked with sweat which was now forming a puddle under her.

"No! How could this happen?" Rarity said, pretending to be horrified. "I guess you win. I must keep my end of the bargain. Not a word of this to anyone else, understand?"

Applejack, Rainbow Dash, and Pinkie Pie nodded, Pinkie doing the Pinkie Promise.

Rarity drank five more cans of Pinkie's soda, then turned around, trying to look unineterested but her heart racing as fast as Applejack's and Rainbow Dash's.

Applejack placed her hooves on Rarity's butt and started rubbing, gently at first.

Rarity liked the feeling of this. She could understand why Pinkie and Rainbow did too. "Harder, please," she said. "Don't hold back. You won fair and square."

"You got it," said Applejack and she started rubbing harder. Rarity's butt was much softer than Rainbow Dash's or Pinkie Pie's, and she loved the feeling of it against her hooves the most.

Then Rarity accidentally let out a loud, wet fart. She blushed, but got some naughty pleasure out of farting in front of three other mares, one of which was right next to her rear.

Rainbow Dash and Pinkie Pie started laughing.

Rarity could feel the pressure build up inside her. "Pinkie Pie, what did you put in this..." A loud fart made its way out of her butt, which lasted three seconds.

"Oh, not much, just some fart powder!" said Pinkie, holding in her laughter until she was finished the sentence. She fell on her back and laughed even harder, accidentally farting twice.

"Of course you did," said Rarity, a little annoyed, but still secretly enjoying this.

As Applejack continued rubbing Rarity's tush, Rarity farted again. This fart was louder and slightly deeper, and lasted five seconds.

Pinkie laughed so hard she ended up peeing herself again.

Then Rarity felt the pressure stronger than ever. She wasn't sure she could go through with this one. She tried to hold it in, which was hard with Applejack rubbing her rear.

PPPPPPPPPPPPPFFFFFFFFFFFFFFFFFFFFFFFFRRRRRRRRRRRRRRRRRRRRRRRRTTTT!

Rarity farted for 13 seconds. This fart was boisterous, wet, and deeper pitched than the last one. Rarity thought she might have made a mess in her shorts, but from the way it felt when Applejack rubbed her butt, she could tell that she didn't.

Rainbow Dash laughed so hard she wet herself this time, and Pinkie laughed harder still.

Rarity didn't fart again for another two minutes, after which she really needed to pee.

"Stop at once," said Rarity. "I need to use the bathroom."

Rarity started to walk toward the field's outhouse, trying to walk slowly so that Applejack would stop her.

Applejack grabbed Rarity's tail and held her back.

"Stop, let me go!" said Rarity, trying to pull herself free of Applejack, but not very hard.

"You're already wet, and you already farted like five times!" said Rainbow Dash. "So what's the worry?" She slapped Rarity's butt with her hoof. She waited for Rarity to yell at her, but Rarity actually liked it so she didn't respond.

Rarity couldn't just let go. Even though a part of her wanted to, it was too hard for a prissy pony like her. So she held it in for as long as she could.

The fart smell had cleared, and Applejack could smell the sweat on Rarity again. She couldn't tell who she liked more this way - Rarity or Rainbow Dash. The ladylike unicorn who usually wouldn't want to smell this way, or the tomboyish pegasus who didn't mind in the slightest.

Rarity let out a whimper as she couldn't hold it in anymore, and the floodgates opened. Her already-wet shorts grew wetter and wetter, and she sighed in relief as the pee flowed down her legs, which she secretly liked the feeling of. She blushed lightly, still feeling ashamed of wetting herself in front of three ponies.

As Rarity kept peeing, Pinkie Pie fell on her back and laughed so hard she wet herself for the third time, while Rainbow Dash couldn't help but stare, feeling aroused at the sight of Rarity peeing in her skintight shorts and enjoying it. She hoped she'd get to be in Applejack's position next time. Applejack would have her turn with her, after all, so hopefully that would be enough.

When Rarity finished peeing herself, she sighed in immense satisfaction, then blushed beet red. She let out a wet fart that lasted only one second, and giggled nervously.

Applejack took a deep breath through her nose. Rarity smelled of sweat and piss just like Pinkie Pie and Rainbow Dash did.

"We should totally do this again sometime!" said Pinkie Pie. "And we should invite Twilight and Fluttershy too!"

"Heavens no," said Rarity, not wanting any more ponies to see her like this. "Fluttershy would never agree to something like this, and I don't think Twilight would either."

"Yeah, I guess you're right," said Pinkie.

"But I... wouldn't mind doing this again," said Rarity, blushing lightly, for she had enjoyed this a great deal.

"I get Applejack's position with Rarity next time!" said Rainbow Dash. "Applejack gets me and Pinkie Pie." Applejack looked a little disappointed, so she quickly added "But you can rub Rarity's butt after she wets herself."

"Deal," said Applejack. She and Rainbow Dash spit on their hooves and did a hoof bump.

Lightning Fetish

Lightning Dust was flying around in search of Rainbow Dash. She wanted to challenge her to another race and prove she was the better flyer!

Lightning Dust flew overhead and saw Rainbow Dash. With her stood Applejack, Pinkie Pie, and Rarity. Applejack was rubbing Rainbow Dash's butt, and Rainbow Dash looked like she was really enjoying it!

Suddenly, Lightning Dust wanted someone to rub her butt. No one else had ever done that, nor had she ever asked them to. So, she decided to wait until Rainbow Dash was done this, and then challenge her again.

...

Rainbow Dash had just finished washing her Equestria Games outfit when Lightning Dust flew in front of her. "I challenge you to a rematch!" she said.

"Haven't you learned your lesson?" said Rainbow Dash. "You can never beat me!"

"This time, the loser has to rub the winner's butt!"

Rainbow Dash's heart started beating faster. As much as she liked having her butt rubbed, she wanted to rub Lightning Dust's butt even more.

"You're on!" said Rainbow Dash.

They put on their exercise outfits, both including skintight white shorts, and then they raced at the same location as before. Rainbow Dash flew as hard as she could, and was slightly ahead of Lightning Dust. But she wanted to rub Lightning Dust's tush, so she flew slightly slower near the end, allowing Lightning Dust to pull ahead and win.

"Ha! I win! I am the superior flyer after all!" said Lightning Dust once they'd had a few glasses of water to drink. She turned around so that her behind was facing Rainbow Dash. "Well, we had a deal!"

"You got it!" said Rainbow Dash a little too enthusiastically. She placed her hooves on Lightning Dust's butt, which was damp and smelled of sweat. She started rubbing Lightning Dust's rear, which felt more firm than Rarity or Fluttershy, but she still loved it, and so did Lightning Dust!

Then Lightning Dust farted in Rainbow Dash's face. She giggled, hoping Rainbow Dash would be grossed out, but Rainbow Dash only laughed. Lightning Dust's heart sank. Rainbow Dash thought it was funny. Still, she was starting to like Rainbow Dash again.

Then Rainbow Dash farted loudly. "Hey, how about a farting contest?"

"You're on!" said Lightning Dust.

Rainbow Dash lifted her leg.

PPPPPPFFFFFFFFRRRRT!

Lightning Dust stuck her rear in the air.

PPPPPPPPPPFFFFFFFT!

Rainbow Dash and Lightning Dust farted for about three minutes, but in the end, Rainbow Dash won with a 16-second fart.

"That was kind of fun," said Lightning Dust.

"More fun than being reckless?" said Rainbow Dash.

"Hold that thought!" said Lightning Dust. "I have to pee!"

Rainbow Dash quickly started tickling Lightning Dust with one of her feathers. Lightning Dust laughed so hard, she wet herself. She blushed as she felt her skintight shorts get wetter and wetter. If she wasn't laughing so hard, she would have sighed in relief.

Once Lightning Dust finished peeing, Rainbow Dash stopped tickling.

"Rainbow Dash!" said Lightning Dust, her shorts soaked with urine.

"It's nothing to be ashamed of!" said Rainbow Dash. "Here!" Rainbow Dash sighed in relief as she let go and peed in her shorts, as she had to go almost as badly as Lightning Dust did. Lightning Dust couldn't believe Rainbow Dash would actually enjoy something like this. And now that she thought about it, she kind of did too, and had no reason to feel ashamed of it.

"I have a lot of fun doing this with Applejack and Pinkie Pie," said Rainbow Dash once she was done peeing. She didn't mention Rarity, as she had promised her she wouldn't. "But we should probably just keep this between the two of us."

Lightning Dust now felt bad about how her recklessness had almost gotten Rainbow's friends killed. "I'm sorry for everything back at the academy," she said. "I'll try not to be so reckless anymore. Will you ever forgive me?"

"I already have!" said Rainbow Dash.

Sunset Shimmer

Something has gone wrong. We don't seem to have an archived copy of that chapter.

Flutter Fetish

Rainbow Dash and Fluttershy were on their way back to Fluttershy's cottage after flying an aerial race against Spitfire and Soarin, which the two Wonderbolts had won. Both pegasi were wearing their Equestria Games outfits - yellow tank top and skintight white shorts, which were now very damp with sweat.

As they landed at the door of Fluttershy's cottage, Fluttershy said "I'm sorry we lost, Rainbow Dash."

"That's all right," said Rainbow Dash. "It was still a fun race."

They walked inside, where Rainbow Dash had brought over several water bottles for after they were done the race. They began drinking from them. Rainbow thought the water tasted funny, but Fluttershy didn't notice, as she was more thirsty than Rainbow Dash. Then, as Rainbow Dash drank her fifth water bottle, she remembered - she had put fart powder in these water bottles, intending to drink it both for her own amusement, and for her next session with Applejack, Pinkie Pie, and Rarity. Rainbow stopped drinking after the fifth bottle, while Fluttershy drank 10 bottles. Rainbow wasn't sure whether she should tell her or not. She knew Fluttershy wouldn't like it, but she still thought it was funny.

Within minutes, Fluttershy was feeling very uncomfortable. Hoping that Rainbow Dash didn't notice, Fluttershy let out a quiet, airy fart. The relief felt good, but she blushed, having farted in front of Rainbow Dash.

Rainbow Dash noticed the expression on Fluttershy's face and knew what she had done. She tried hard not to laugh. Fluttershy felt more embarrassed, and accidentally farted louder than before. Rainbow Dash fell on her back and started laughing harder.

"Um, excuse me," said Fluttershy, blushing beet red.

Rainbow stopped laughing, not wanting Fluttershy to feel too bad. "Don't feel ashamed, Fluttershy," she said. "I think it's cute and funny when you fart."

"You really mean that?" said Fluttershy, blushing more from something besides shame.

"Of course I do," said Rainbow Dash. She farted loudly and chuckled.

Fluttershy began to relax, and let out a loud fart that lasted seven seconds. She was still blushing, but giggled a bit, while Rainbow Dash laughed harder, accidentally farting a few times which made her laugh even harder.

"Rainbow Dash, can I ask you something?" said Fluttershy, releasing a silent fart that Rainbow didn't notice. Rainbow nodded. "Pinkie Pie told me what she, you, and Applejack like to do sometimes."

She hadn't mentioned Rarity. It seemed as though the fast-talking mare had kept her word.

"And, I was wondering... could you maybe rub my rear?" She blushed a little. "I've always wanted you to do that."

"Sure," said Rainbow Dash, her heart pounding. She had always wanted to do this to Fluttershy but had been sure Fluttershy would never want her to.

Fluttershy turned around so her tush was facing Rainbow Dash. Rainbow put both her hooves on Fluttershy's butt and started rubbing. Her butt was as soft as Rarity's, and she loved it! Fluttershy also took great pleasure in this. Then, she accidentally farted in Rainbow Dash's face, and blushed. But Rainbow Dash giggled, and Fluttershy relaxed, knowing Rainbow didn't mind. Fluttershy farted again, this time intentionally, giggling a bit.

After a while, Fluttershy said "Now, Rainbow Dash, can you... slap my rear?"

"What?" said Rainbow Dash.

"I want you to slap my rear ten times," Fluttershy said, blushing a little. "As hard as you can."

"I can slap pretty hard," said Rainbow Dash, but she didn't argue much. This was what Fluttershy wanted. Rainbow Dash slapped Fluttershy's butt with her hoof, causing her to squeal. "Was that too hard?"

"No, it was just right," said Fluttershy. "Now, nine more times."

Rainbow Dash spanked Fluttershy again, and again. Fluttershy felt pain explode through her rear, but loved every second of it.

After Rainbow swatted Fluttershy the tenth time, she turned around. "Now do the same thing to me," she said.

Fluttershy raised her hoof... and patted Rainbow's behind lightly.

"Come on, you can do better than that!" said Rainbow Dash. "Slap as hard as you can!"

"If you say so," said Fluttershy. She raised her hoof and slapped Rainbow's butt surprisingly hard.

"That was awesome! Keep going!"

Fluttershy swatted Rainbow's tush nine more times, Rainbow Dash greatly enjoying each one. Her butt hurt when it was over, but she didn't mind.

"We should do this again sometime," said Rainbow Dash. "Of course, you'd probably prefer if it was just us and not Pinkie Pie and Applejack." She didn't mention Rarity either, also having promised never to tell that she was involved in their fetish activities.

"If it's all right... can I ask one more thing of you?" said Fluttershy. Her heart was racing; she had never asked this of anyone else before, but she had just had Rainbow Dash rub and slap her butt, and done the same to her, and was no longer able to feel shame farting in front of her, plus Pinkie had said Rainbow thought it was fun to wet herself, so she was sure to accept this.

"Anything you want," said Rainbow Dash.

Fluttershy whispered something into her ear. Rainbow couldn't believe what she was hearing. Fluttershy's fetishes ran deeper than she could have imagined, maybe even deeper than Applejack's. But it would be just as fun for her as it must be for Fluttershy, so, trying to act cool, she said "Yeah, I can do that."

"So, until then..." said Fluttershy, turning around so that Rainbow Dash could continue rubbing her butt with her hooves.

About an hour later, Fluttershy had to pee badly. All the water bottles she drank were affecting her. "I need to use the little filly's room," she said, and ran toward the bathroom.

Rainbow Dash zipped over in front of her to block her path, facing away from her. "I won't let you," said Rainbow Dash.

Fluttershy pressed her head against Rainbow's butt and tried to push her out of the way. "Please, I really need to go."

Rainbow Dash responded by sitting on Fluttershy's head. Rainbow's butt was still sweaty, but she was able to breathe. She tried pulling her head out, to no avail.

The pressure in her bladder grew stronger and stronger. She knew she couldn't hold it long once she needed to go this bad. She remembered the time she had worn one of Rarity's skintight white outfits as part of her fashion show, but had forgotten to use the bathroom before. The show didn't last long so she had raced home, but she didn't make it. Rarity was upset that Fluttershy had peed in one of her outfits, but she didn't give her a hard time because she knew it was the last thing she needed.

Then Rainbow Dash farted loudly. It smelled awful, and Fluttershy kept trying to pull her head out from under Rainbow Dash's butt, but still couldn't. Her behind was in the air, and she also let out a loud fart, to which Rainbow Dash chuckled.

Fluttershy was in desperate need of a bathroom and she knew she couldn't hold it much longer. Then, Rainbow Dash farted on her again, which lasted five seconds. This was too much for Fluttershy, and she felt her shorts grow warm and wet as she began wetting herself. She could feel waterfalls of pee flowing down her legs and forming a puddle at her back hooves.

Rainbow heard the sound of Fluttershy peeing. She felt so aroused by this, she had to take a quick peek. She started to lift her butt off Fluttershy's head.

"No, not yet!" said Fluttershy. Rainbow sighed and sat back down on Fluttershy's head.

Fluttershy had never thought she would do this before, but she loved every moment of it. The warm release, the feeling of the pee flowing down her legs as her skintight shorts grew wetter and wetter, and the naughty feeling of doing something like this and playing out her fetishes. When she had wet herself after Rarity's fashion show, despite being embarrassed at Rarity finding out, she had secretly enjoyed it. While she would sometimes pee in her Equestria Games outfit when no one else was around, and wash it to hide this from anyone, she had always wanted to try it combined with another mare sitting on her head, having seen Pinkie do this to Rainbow once. Rainbow Dash was the perfect pony to satisfy this for her.

Once Fluttershy finished peeing, Rainbow Dash stood up and turned around. Fluttershy was blushing lightly, but looked satisfied all the same. Her shorts were soaked with urine, and she smelled of it too, along with a bit of sweat and farts. In that moment, Rainbow Dash peed herself, even though she didn't have to go that bad. Both she and Fluttershy really enjoyed this so why shouldn't she do it in front of her? She sighed in immense satisfaction as she soaked her skintight shorts.

As she finished wetting herself, Rainbow Dash said "How was that? Was the farting too much?"

"No, it was perfect," said Fluttershy. "It's actually fun when you fart on my head." She blushed lightly.

"We'll have to do this again," said Rainbow Dash. "Maybe we could switch places sometime."

"I can't wait," said Fluttershy. "But... let's not involve any of the other ponies. Let's keep this between the two of us."

"Don't worry," said Rainbow Dash. "I'd never do that to you."
