Author's Notes:

Just a chapter with details on what they're doing there, which is the same as Rarity and Fluttershy in an earlier chapter but for those really into this I want to describe it with all of them that are involved now. So, the only thing new is really the three new characters. To release the full extent of my fantasies (again), but with the characters enjoying it as well.

Mostly fetish fuel, except for one bit at the end.

It had been a few days since Rarity, Fluttershy, Rainbow Dash, Pinkie Pie, and Sunset Shimmer had gone to the mud field together for the first time. Over those few days they had either been busy with work or hanging out with Twilight and Applejack. But today all five of them had the entire morning to themselves, and it was a nice day. It had just rained last night so the mud would be very wet today.

They met at the mud field. Rarity was wearing her light blue tank top and short, purple, skintight shorts. Fluttershy was wearing her outfit that was identical, except her tank top was white and her shorts were green. Rainbow Dash was wearing one of her favorite exercise outfits, short skintight shorts and a matching midriff tank top that were the same shade of blue as her hair. Pinkie Pie was wearing her white and pink T-shirt and short, tight jean shorts.

Sunset was so excited to do this again that she had forgotten to change out of her purple pajamas. Or take her morning pee, but where she was going, she could just do it there.

"There are a lot more horses here than when Rarity and I first found this place," said Fluttershy. She brought her geode with her in addition to her magic gem. "Now, horsies, we'd love it very much if you'd sit on us whenever we lay down behind you, and fart on us. Get back up if you go for a minute without farting. And if you have to poop when we lay behind you, do it on us."

The horses nodded, looking as though they would enjoy this very much. A few of the new horses that weren't there last time whinnied with excitement.

Pinkie Pie was holding herself and doing the pee dance. She really needed to go, for she had drank a lot of soda last night. Usually she'd just pee in the bed when she woke up, and then magically dry herself and the bed (whenever she felt like it), but she was saving it for here.

"I need to pee SO BAD!"

Rainbow smirked, touched her gem, and let out a boisterous fart that lasted nine seconds.

Pinkie burst into a fit of laughter, and her shorts quickly grew warm and wet.

"Rainbow Dash!" said Rarity, but with amusement in her voice, while Fluttershy giggled quietly.

"I love making her wet herself from laughing too hard," said Rainbow. "I know she likes it, and she can dry off whenever."

Pinkie stopped laughing, but was still peeing. "I can't think of any other way I'd have rather peed this morning!" She slapped Rainbow's butt lightly.

"I haven't taken my morning pee yet," said Sunset. She sighed as she wet her pajama pants, enjoying the feeling of the wetness soaking her legs.

"Looks like someone forgot to get dressed this morning," said Rainbow, slapping Sunset's butt playfully.

"Yeah, I realized on the way here. I was just too excited to do this again."

Rarity and Fluttershy touched their magic gems. Both let out an airy fart, then a louder fart. And, as they started to pee, they noisily released a big mess into their shorts, which didn't stop, because whenever they felt like they were about to run out, they'd use their magic gems to refill their bowels and bladders.

Rainbow Dash started to laugh at the gassy sounds Rarity and Fluttershy were making as they soiled themselves. She quickly touched her gem to overflow her bladder, and continued to laugh her butt off, wetting her shorts as planned.

Before long, Rarity and Fluttershy's shorts started to overflow, with hyperscat oozing out of the leg holes, down their legs, and onto the mud below, while the pee continued to flow down their beautiful legs. Both girls were really enjoying themselves.

As soon as it became silent (aside from Rainbow's laughter), Pinkie quickly touched her gem and began farting loudly, but not soiling herself... yet.

The next time Rarity refilled her bowels, instead of hyperscat, she pushed out a continuous log that continued to overflow her very dirty and smelly shorts, while Fluttershy continued to fill her shorts with hyperscat.

After over a minute, they finally stopped, though Pinkie Pie was still farting.

"Did we overdo it?" said Fluttershy, who was not blushing and had really enjoyed this.

"There's no such thing as overdoing it here, darling," said Rarity. She let out a wet fart and giggled.

Then they rolled around in the mud for a few minutes, until they were completely covered in it. Fluttershy and Rarity sat for another minute, wiggling their butts against the mud a bit to squish the mess in their shorts.

Rarity walked over to Rainbow Dash and lay facedown in the mud. Rainbow knew what this meant, so she sat on Rarity's butt. She touched her gem and began farting non-stop. These farts were loud, boisterous, and occasionally Rainbow would touch her gem slightly and let out more than just a fart.

Rarity touched her gem, and said "Dashie, can you please get off? I have to go to the bathroom!"

Rainbow knew Rarity didn't really want her to get up. They were here to go to the bathroom on themselves and each other and enjoy it, as she had already done. She was just putting on a show and acting like her ladylike self to get a little more dirty pleasure out of it.

Rainbow let out another loud fart, and Rarity peed. Loving every second of it.

"Can someone do that to me now?" said Fluttershy, who couldn't hide her excitement and sounded very enthusiastic.

Sunset walked over to her. Fluttershy lay facedown and Sunset sat on her butt.

"Ooh, it feels squishier than last time," said Sunset. Fluttershy giggled.

Sunset touched her gem and farted repeatedly, while simultaneously peeing herself. Fluttershy liked the feeling of Sunset farting while sitting on her, just like Rarity did. And peeing on her.

Fluttershy farted a few times, which Sunset liked, and then touched her gem for something else.

"Um... Sunset... can you get up now? I really need to pee."

Sunset almost got up, but remembered, Fluttershy couldn't really want her to get up. Not after how much she had wet and soiled herself earlier.

"You'll just have to go in your shorts," said Sunset, winking.

Fluttershy giggled, unable to put up the act for too long. She sighed in relief as she peed her shorts again.

"Can I get up now?" said Sunset after touching her gem. "I need to do more than just pee."

"No, just sit still," said Fluttershy. "If you have to go, go in your pajamas."

"Uhhh... I can't hold it any longer..." Well, maybe she could, but like Rarity and Fluttershy, she was just pretending. She released the contents of her bowels and bladder into her pajamas. Fluttershy could feel Sunset wetting and messing herself on her and giggled. Sunset let out a moan of pleasure.

Pinkie Pie, meanwhile, was just having fun farting as loud as she could. Occasionally she got on all fours, lifted her leg, and peed like a dog, but through her shorts. Then she laid facedown next to the nearest horse, which quickly sat on her butt. Pinkie used her gem to make both herself and the horse fart repeatedly. Occasionally peeing, while Rainbow Dash farted on Rarity and Sunset farted on Fluttershy. With Rarity and Fluttershy occasionally farting as well.

Eventually, they stopped what they were doing and did something else.

"Who wants to ride on my back?" said Rarity, getting down on all fours.

Fluttershy climbed on Rarity's back, with one leg on either side of her, and she started to walk through the mud like a pony. Occasionally Rarity would let out a loud fart, or pee herself in the middle of walking, and just as often Fluttershy would do the same. Rarity liked the feeling of Fluttershy peeing on her. At one point Rarity messed herself rather noisily.

At the same time, Rainbow Dash said to Pinkie Pie "Let's fart non-stop for at least a minute!"

Pinkie squealed in excitement. "Wait a minute..." She touched her gem, then squealed again, peeing herself this time.

They touched their gems and farted. Pinkie's fart was higher-pitched than Rainbow's. Both were very loud and very wet. Both their farts kept going past a minute without stopping, and if Rainbow and Pinkie thought they were going to run out of gas, they quickly recharged with the gems. Both were laughing very hard at these ridiculously long farts.

A minute in, Pinkie touched her gem, and Rainbow suddenly peed herself as she laughed. Rainbow smirked and touched her gem. Instantly Pinkie's fart got wetter and sloppier as it stopped. Her eyes went wide with surprise as she filled her shorts with hyperscat, and she giggled. "Good one Dashie!"

Rainbow was still farting, until suddenly the fart turned into a mudslide that soiled her shorts even further. She chuckled. "Of course you couldn't resist doing it back to me, could you?" said Rainbow, having enjoyed her unexpected accident.

"I didn't do it," said Pinkie, who hadn't touched her gem since soiling herself.

"I did," said Sunset, who was currently laying facedown, peeing, and being farted on by a horse, which was sitting on her butt as usual.

Once Fluttershy got off Rarity, Rarity made the nearest horse have to poop, and positioned her head directly under it while laying on her back. Immediately her face was buried in a wet, stinky pile of manure. Rarity lay there for a while, enjoying how dirty she was. She touched her gem, and simultaneously wet and soiled her shorts yet again.

Rainbow noticed this. One of the horses had just taken a dump of its own accord, so Rainbow quickly ran over to the pile of dung and planted her face in it.

Then the horse sat on her head. Muffled screams came from under the horse's butt, but Rainbow liked it. She used her gem to create a little air pocket around her mouth so she could breathe, and then made the horse fart on her head several times, while making herself fart, pee, and poop for the entire length of it.

"Pinkie Pie..." said Fluttershy. "Can you sit on my face?"

"I just soiled myself a lot," said Pinkie.

"I'd have asked you to soil yourself if you hadn't."

Pinkie paused to mess herself again, and then sat on Fluttershy's face while Fluttershy was laying on her back. Pinkie's shorts were filled with poop and it was very messy and smelly. Fluttershy liked it.

Then Pinkie farted, and giggled. Fluttershy didn't mind, besides, it didn't smell as bad as they both did now. Fluttershy touched her gem and started to pee, her legs raised slightly.

Rarity, meanwhile, had finally sat up and wiped the horse shit off her face.

"Smell my butt," said Sunset.

Rarity sniffed Sunset's very dirty rear end.

"It smells absolutely foul. And I love it!"

Sunset let out a boisterous fart, releasing another mess into her panties and pajamas. Both she and Rarity giggled.

Rainbow stopped making the horse fart, and after a minute, the horse stood up, as Fluttershy had instructed. Rainbow positioned herself so that her butt was aligned with the horse, and made the horse gassy again. The horse sat on Rainbow's butt, and both it and Rainbow continued to fart repeatedly.

After this round, Rarity sat on Rainbow Dash's butt, peeing and farting on her, while Fluttershy did the same to Sunset. Of course, Rainbow and Sunset were peeing and farting as well. Rainbow even used her gem to make Rarity mess herself. Or at least need to poop, Rarity did the rest on her own. Pinkie had a horse sit and fart on her again, peeing herself less than a minute in, and then had it dump a major pile of manure on her. Only ten second after this, Pinkie pooped her shorts again.

Once they'd had their fun, they just sat in the mud side by side, wet, dirty, and very smelly, having greatly enjoyed today.

"Girls?"

Rarity, Fluttershy, Rainbow Dash, Pinkie Pie, and Sunset turned in the direction the familiar voice had come from. Twilight Sparkle and Applejack were standing at the edge of the mud field. Twilight was wearing her purple Legend of Everfree shorts, and Applejack was wearing jeans. The five girls had been having so much fun that they hadn't realized their other two friends were standing there the whole time and had seen everything.

None of them spoke. Rarity accidentally farted, and Fluttershy peed. Pinkie deliberately, unabashedly, and noisily messed herself again.

Then Twilight spoke again.

"Do you mind if we join in?"
