The ponies play out their shared fetishes while wearing panties.

Having discovered they share the same kinks, the Main 6 satisfy them in pairs of two while wearing panties designed by Rarity specifically for this event. They start with the tamest fetish, and then build to the dirtiest, with each pair going about it in their own way, also providing entertainment to Spike, who merely finds it funny.

Contains: Panties, butt rubbing, farts, wetting, and messing. And OoC and stretchy scenarios, the usual. Another story that's pure fetish fuel, so don't take too seriously.

It took a while but I finally got the confidence to write here again. If you haven't read and loved my previous stories with these fetishes, then turn back, even if you have the fetishes yourself. Unless you don't mind if the quality isn't great.

Butt Rubbing in Panties

The Main 6 stood in a room in Twilight's castle, wearing the new "outfits" Rarity had designed for them.

Each of them was wearing a pair of tight panties which covered most of the butt. Twilight Sparkle's were white, Rainbow Dash's were pink, Rarity's were purple, Pinkie Pie's were light blue, Fluttershy's were green, and Applejack's were red.

They had all eaten a certain type of meal cooked by Pinkie Pie, and drank lots of cider and water. They each stood next to the pony they were most attracted to: Twilight Sparkle and Pinkie Pie, Rainbow Dash and Applejack, and Rarity and Fluttershy.

Spike was in the room as well. The ponies didn't mind him witnessing their activities, he just thought it was funny. Although they did get some sexual pleasure out of what they were about to do, they also liked it in less sexual ways as well, and as they all shared the same kinks, they were at ease doing it in front of each other when they were all in the room. But they'd never do it in front of anyone but each other and Spike.

They started with the one activity they could do at this time: Rubbing each others' butts.

Twilight, Rainbow, and Rarity faced away from their respective partners, having decided it was their turn first.

Pinkie Pie started rubbing Twilight's butt with her hooves. She rubbed fast and energetic, and Twilight giggled at the feeling of it. She really liked the way Pinkie did this.

Pinkie also liked the feeling of Twilight's tushie, which was not particularly firm or soft, but somewhere in between. It didn't make a difference to her the feeling of the panties or not, but they sure made it funnier for her, causing Pinkie to giggle as well.

Applejack rubbed Rainbow Dash's butt slower but harder than Pinkie. She wasn't into fashion much but she did like the feminine touch that the pink panties added to the tomboyish pegasus, and made her butt all the more arousing to rub. Even though she loved Rainbow Dash as tomboyish as she was. Rainbow's butt was very firm, just how Applejack liked it.

Rainbow loved it when ponies rubbed her butt as hard as possible and Applejack was the perfect pony for this. She, too, felt a sort of naughty pleasure of being in pink underwear for it.

Fluttershy rubbed Rarity's butt very gently, but making sure she didn't miss an inch of it. Rarity's butt was very soft, and, in Fluttershy's opinion, the loveliest rear end in Equestria. She also liked the feel of the panties as well.

Rarity loved how delicately yet thoroughly Fluttershy was rubbing her behind. She couldn't have asked for a better pony than Fluttershy.

After five minutes, the ponies switched.

Twilight caressed Pinkie's butt. She and Twilight had very similar butts, and Pinkie's butt was just what Twilight loved to rub the most. Not too hard and not too soft, somewhere in between.

Pinkie giggled at Twilight rubbing her tushie while in a pair of panties, finding both butts and underwear to be funny, while at the same time enjoying the butt massage itself.

Rainbow Dash rubbed Applejack's butt just as hard as Applejack had done to her. Applejack liked it as hard as Rainbow Dash did.

Applejack's butt was a bit softer than Rainbow Dash's, also Rainbow's preference.

Rarity massaged Fluttershy's butt harder than Fluttershy had, but still making sure her hoof touched every inch of it. Fluttershy's butt was just as soft as Rarity's and she really loved it, not to mention the feel of the panties she had designed. Put together, the panties and Fluttershy's butt were perfect.

Fluttershy closed her eyes as she enjoyed every second of Rarity rubbing her tush. She loved the way Rarity did this, every part of it.

Five minutes later, they switched around, and kept doing so for half an hour until they felt it was time for the next thing.

Author's Note

I considered pairing Rainbow Dash with Fluttershy and Rarity with Applejack, but I decided on Appledash and Rarishy instead. They seem to go so well together for this kind of thing, plus RD and AJ get competitive in the next three chapters.

Farting in Panties

Author's Note

Warning: This chapter contains an early wetting scene, but only one. I hadn't decided to split this into four chapters yet when I wrote this.

Farting in Panties

The ponies all felt a gurgling in their stomach. But they kept rubbing each others' butts until...

*ffffrrrrrt*

Twilight accidentally farted, warming up her panties a little. She blushed lightly while Pinkie giggled. "Excuse me... I didn't think that'd happen so soon."

"Hey, we're here to fart in each others' faces!" said Pinkie. She and Twilight turned around, and Pinkie stuck her butt in Twilight's face.

PPPPPPPFFFFFFFFT!

Pinkie let out a loud, high-pitched fart in Twilight's face. Twilight sniffed and sighed in satisfaction. Then, feeling another one coming, she excitedly turned around, raised her tush in the air in front of Pinkie's face, and let out a louder, wetter fart.

PPPPPPRRRRRRRRRT!

When Rainbow Dash and Applejack heard Twilight and Pinkie farting, they stopped their butt massages.

"Whoever farts the longest wins!" said Rainbow Dash.

"You're on!" said Applejack.

They spit on each others' hooves and did a hoof bump. Rainbow let out a short but loud fart. Applejack lifted her leg.

BBBBBBBRRRRRRRRRT!

"Let's see you beat that," said Applejack.

"With pleasure," said Rainbow Dash, and she lifted her leg.

BBBBBBRRRRRRRRRRAAAAAAAAP!

Fluttershy was still rubbing Rarity's butt, and Rarity let out a silent fart. Fluttershy could feel a bit of a breeze, and could easily smell the fart, for Rarity's farts were the stinkiest. But Fluttershy didn't mind. She liked the smell of Rarity's farts.

She stopped rubbing Rarity's butt and turned around. Rarity started to rub her butt. Fluttershy let out a silent fart of her own, warming her panties slightly. Similar to before, Rarity could feel it and smell it, and loved it.

Spike was laughing his butt off at the sound of the ponies farting.

Twilight farted loud, wet, and long with her butt inches away from Pinkie's face. Then Pinkie farted in Twilight's face the same way, but higher-pitched. Both mares giggled at each other's flatulence, occasionally slapping each other's butts after being farted on.

Rainbow Dash farted loud for 13 seconds. Applejack let out a slightly deeper-pitched fart for 12 seconds, and was annoyed that she was losing to Rainbow Dash yet again.

Once they finished warming up with silent farts, Rarity and Fluttershy began farting louder.

Rarity would always be the first to fart loudly, so that Fluttershy would know she didn't have to hold back.

FFFFFFFFFRRRRRRRRRRRRT!

A very loud fart made its way out of her butt. Rarity blushed lightly but giggled. "Your turn, Fluttershy."

Fluttershy giggled and raised her butt in the air.

PPPPPPPPPPFFFFFFFFFFFT!

Fluttershy farted slightly quieter but just as long as Rarity. She also blushed lightly, but was really enjoying this.

After six minutes of farting, Twilight and Pinkie stopped farting in each others' faces and pressed their butts against each other.

PPPPPPFFFFFFFFT!

FFFFFFFFRRRRRRT!

Both mares giggled, each enjoying the vibration of her partner's farts against her butt.

Rarity and Fluttershy were also doing the same thing, farting into each other's butts louder and more unladylike than Twilight and Pinkie, and each feeling her partner's farts and giggling at the sensation.

Rainbow Dash and Applejack were doing no such thing, farting for competition rather than pleasure, although their farts were louder, longer, and more unladylike than Rarity and Fluttershy's.

The ponies were stinking up the room, so Spike opened a window, then resumed his uncontrollable fit of laughter. Good thing he'd used the bathroom right before this started.

They knew very well that, not only had Pinkie cooked large amounts of food that made them very gassy, but she had also put fart powder on it, so their farting wouldn't subside any time soon.

They farted for half an hour straight, and after Twilight let out a particularly long and wet fart, Pinkie let out a moan of pleasure and started to pee in her panties.

"Pinkie, I thought we weren't at that part yet!" said Twilight, who didn't feel a particular need to pee right now.

"I couldn't help it! I drank so much soda before I got here." She sighed as she continued peeing, letting out several farts as she did so. She really enjoyed the warm release. One time she had wet her exercise shorts in front of the other ponies out of excitement, and been unable to hide how much she loved it, leading to them realizing they had the same kinks.

"Oh, it's all right. With all that cider we drank you'll surely have to pee again soon."

"15 seconds!" said Rainbow Dash after her latest fart. "I'm in the lead once again!"

"We'll see about that," said Applejack.

Rarity and Fluttershy farted loudly at the same time, and giggled, as this was totally unexpected.

They continued to fart for half an hour later, before they started to run out of gas, their farts becoming less frequent. But, around this time, they also had to pee. Even Pinkie Pie.

Peeing in Panties

Author's Note

Likewise, there is one fart scene here, but it's minor.

Peeing in Panties

"I need to pee," said Twilight. "How about you, Pinkie Pie?"

"Even after half an hour ago, I gotta go pee real bad!" said Pinkie.

"I win the farting contest!" said Rainbow Dash, slapping her butt with her hoof.

"Well, let's see if you win the holdin' contest," said Applejack.

They repeatedly filled two large mugs of cider and guzzled them down, showing each other the empty mugs so they knew they weren't cheating.

"I need to pee," said Fluttershy quietly, crossing her legs.

"I need to use the bathroom rather urgently as well," said Rarity. She paused to let out a loud fart that she suspected would be her last today.

They resumed rubbing each others' butts, trying to get into a relaxed position to lose control.

Twilight and Pinkie just sat with their legs crossed, waiting to get really desperate.

"Ugh, I don't think I can drink any more," said Applejack.

BUUUUUUUUUUUUUUURP! "Me neither," said Rainbow Dash. "Now I REALLY gotta go!"

Applejack and Rainbow Dash did the pee dance, each trying to avoid being the first to wet her panties.

Every two minutes this time, Rarity and Fluttershy would alternate between rubbing each others' butts. They could feel their need to pee increase with each minute. Any other situation they'd be desperate to avoid wetting themselves, but here they wanted to relax, ignoring the pressure in their bladders, and feel a loss of control.

About half an hour went by. Spike was eating popcorn, wondering who was going to have an accident first.

"I can't... hold it..."

Rainbow Dash sighed in relief as she wet her pink panties, enjoying the feeling of the pee flowing down her legs and forming a big puddle under her.

"Ah win!" said Applejack, and she started to pee in her panties as well. "Ahhhhh..." Their puddles joined together and rapidly expanded.

"You win this time, but only cause I really wanted the relief and couldn't wait a second longer," said Rainbow Dash.

Applejack raised an eyebrow.

"Actually, no, I really couldn't hold it," Rainbow admitted.

Fluttershy was rubbing Rarity's butt when Rarity finally lost it. She could feel her purple panties grow warm and wet, as well as a naughty pleasure from an involuntary loss of control. She sighed in relief as a puddle grew under her.

"All right Fluttershy, let's switch," said Rarity.

"I... I'm already peeing."

Fluttershy's front hooves were on Rarity's rear end, making her unable to hold herself, and as soon as Rarity had started peeing, Fluttershy had lost it as well. Her stream soaked her green panties and her back legs, making another big puddle to join Rarity's.

"I'm so sorry," said Rarity.

"It's all right. It's just as much fun peeing in this position as it would be if you were rubbing my butt." And she meant it, for whichever side of the butt massage she was on she was very relaxed. She let out a long sigh of relief and satisfaction, which reassured Rarity.

Twilight and Pinkie were really desperate now, and watching the other ponies pee made Pinkie leak a little into her already-wet panties.

"I think we're desperate enough," said Twilight. She stood up and let it all out. Her panties went from white to yellow as they became soaked, and the pee gushed down Twilight's legs. She let out a sigh of immense relief, though she hadn't had to go as badly as Rainbow Dash and Applejack had.

"Oooh!" Pinkie stood up and started peeing as well. "Ahhhhh..." Then she giggled at how funny it was that she and Twilight were peeing in their underwear.

Spike laughed some more. He couldn't think of anything funnier than ponies farting and peeing in panties. It was even funnier for mares to do it than stallions, though that was all he thought of it.

Each of them peed for a minute except Rainbow Dash and Applejack, who peed for three minutes. Once they were finished, their panties and back legs were soaked, there were some big puddles in the room, and they felt immensely relieved, as well as having taken extreme pleasure in wetting their panties. Even Rainbow Dash, despite having lost the holding contest to Applejack.

They sat in the puddles they had made on the ground - each pair's puddles were one early into their wetting - and waited until the final phase of their exercise could take place. Their panties were now completely drenched and smelled of pee and farts.

Messing in Panties

Only twenty minutes later, they began to feel the effects of the other portion of the meal they had eaten.

At first, they started farting again. They stood up and farted in each others' faces, and, a minute later, their pee-soaked butts, even Rainbow Dash and Applejack.

Then, they felt a pressure in their bowels that was more than just a fart. They still let out a few more farts which were wetter, smellier, and, soon enough, started to stain their panties.

As the pressure grew, they each stood side by side, but facing opposite directions, so that each pony's head was close enough to the other pony's rear to get a good view.

"Wanna see how long we can hold it for best out of three?" said Rainbow Dash.

"You're on," said Applejack.

Only ten minutes went by. Then, Rarity felt another fart come, and, rather than let just it out, she pushed as hard as she could.

PPPPPPPPPBBBBBBBLLLLLLLLLLLRRRRRRRRRRT!

Rarity sighed as she released a wet brown mess into her purple panties. Fluttershy could see a big brown bulge on Rarity's butt.

Since Rarity messed herself, now it was her turn. Fluttershy closed her eyes tight and pushed out an equally wet, equally smelly mess into her green panties. She let out a sigh once she was done.

"Ooh, it's that time now?" said Pinkie, and she released a ton of hyperscat into her blue panties, to the point it overflowed and leaked down her legs.

"Wow, you messed yourself pretty bad," said Twilight.

"I ate a lot more than you," said Pinkie cheerfully.

"My turn now!" Twilight raised her rump in the air.

PPPPBBBBBBBBBBLLLLLSSSSSSSSHHHHRRRRRT!

Twilight's eyes went wide as she filled her panties with diarrhea. The mudslide flowed down her back legs while turning the butt of her panties brown, and what few particles were close to solid caused her underwear to bulge at the back. It smelled even worse than Pinkie's mess. When she was done soiling her panties, she looked as though she had sat in a big mud puddle.

"Looks like someone's got the trots!" said Pinkie, giggling, while Spike was laughing again.

Twilight also giggled. She hadn't been expecting it to happen this way, but she still liked it.

Ten more minutes went by while Rainbow Dash and Applejack continued to hold it, each trying to outlast the other.

Finally, Rainbow Dash couldn't hold it anymore. She groaned as she felt a log make its way out of her butt and into her panties.

Applejack had a clear view of the rapidly-expanding bulge on Rainbow Dash's butt. "Ah win again!" She wasted no time in letting her own logs of poop ooze out into her red panties.

Once Rainbow's first two logs were in her panties, she released the third wave, which was noisier and a lot wetter, much like Rarity, Fluttershy, and Pinkie. Although she had lost the contest, she could at least still enjoy the dirty sensation of messing her wet panties. It wasn't long before Rainbow's panties were overflowing with manure.

After they both finished, each pony rubbed her butt against her partner's butt, squishing each other's messes between them. As 40 minutes had gone by, they peed again, for the remainder of what they drank had now gone through them.

Then they sat around in a circle, letting out a collective sigh of satisfaction. They were very wet, dirty, and smelly, especially their heavily soiled panties, and they were sitting in Rainbow Dash and Applejack's puddle, and they all got a naughty pleasure out of every bit of it.

"That was awesome!" said Rainbow Dash.

"You can say that again," said Spike, who had enjoyed the show. Of course he was clear this was to be kept between the seven of them.

"We're gonna be having so much fun with these panties!" said Pinkie Pie.

"We'll need to wash them really good," said Twilight.

"It doesn't matter if they're still stained or if they still smell a little," said Rarity. "I made these panties specifically for using as a toilet on our sessions. We won't be wearing them anywhere else."

Twilight cleaned up the mess they had made in the room with her magic. She didn't bother using air freshener because the window was open so the room would air out soon now that it was clean. They also dumped the mess out of their panties and flushed it down the toilet.

Then the ponies took a long bubble bath, still wearing their dirty panties. With their usual pairings, they especially scrubbed each other's butts with extra soap until they were completely clean and didn't smell. Their panties still had a bit of a brown stain on the butt, but they didn't care - they knew they'd be wetting and messing them again for years to come!

Author's Note

I changed the last paragraph a bit to include the butt scrubbing in the bath.
