Rarity, Fluttershy, Twilight Sparkle, and Applejack met up at the mud field. Rarity had given Twilight and Applejack magic gems since they had first joined them at the mud pit.

Rainbow Dash, Pinkie Pie, and Sunset Shimmer were busy at this time, but at least the four of them could have fun together.

Rarity was wearing her light blue tank top and skintight purple shorts. Fluttershy was wearing her usual white tank top and green skirt. Twilight was wearing her Legend of Everfree outfit, consisting of a blue T-shirt and short, fairly tight purple shorts, and Applejack was wearing a white and green T-shirt and short, tight jean shorts that looked a little dirty already.

Twilight was looking a little fidgety.

"Are you all right, Twilight?" said Rarity.

"I'm fine. I just didn't take my morning pee, and held it all the way here. Ooh! I'm so excited to be doing this again!" Twilight squealed and started to pee in her shorts.

Rarity, Fluttershy, and Applejack giggled.

Twilight blushed lightly, but remembered they were all here to do this kind of thing and she didn't have to feel any more ashamed of it than all the times she had wet and messed herself last time. She touched her magic gem and let out a loud fart before she was done peeing.

"Well, let's not keep the horses waiting," said Rarity, and they walked forward into the mud field. The horses looked happy to see them again.

"So Fluttershy," said Twilight, "remember how last time you had me sit on you while farting, wetting myself, and messing myself?"

"Yes," said Fluttershy.

"Well, can you do that to me this time?"

"Okay. All of it?"

"Of course."

Twilight laid facedown in the mud, and Fluttershy sat on Twilight's butt. She touched her gem and let loose with some explosive wet farts. Twilight touched her gem and began to fart just as loud. Both she and Fluttershy enjoyed this.

Meanwhile, Rarity said "I would very much like to do what we did last time, Applejack." She got down on all fours, getting her hands and lower legs dirty.

Applejack climbed on Rarity's back. "Yeehaw! Ride 'em cowgirl!" Applejack slapped Rarity's butt, and she started running forward like a horse as fast as she could. Mud splattered her outfit a bit, but of course she didn't mind.

Rarity touched her magic gem. "Applejack, I need to use the bathroom."

"Just go in your shorts," said Applejack, knowing what Rarity's intentions were. "That's what I do." She touched her gem, filling her bladder instantly, and she started to pee. First her stream soaked her jean shorts, then it soaked Rarity's shirt. She sighed in relief.

Rarity loved the feeling of the warm wetness, and it just made her overflowing bladder give out without even having to release it herself. Rarity also sighed as her shorts grew warm and wet, and pee flowed down her legs, as well as trickling through the crotch of her shorts and onto the mud below.

"Who said you could stop movin'?" Applejack slapped Rarity's butt again. Rarity giggled and continued to move, both her and Applejack still peeing.

Meanwhile Twilight had also filled her bladder with her gem and was seeing how long she could hold it.

Fluttershy touched her gem and started to pee in her dress. "Ahhhhhh..."

Twilight could feel Fluttershy peeing all over her already-wet shorts, and giggled as she started to pee right where she was.

Not long after Rarity finished peeing, she stopped for a second to touch her gem, and as she continued giving Applejack her ride, she let out a boisterous wet fart.

"Nice one, Rarity," said Applejack. She touched her gem and let out a deeper-pitched but equally wet fart.

Rarity giggled, loving the feeling of Applejack's fart vibrating against her back. She let out several more farts, and when she touched her gem, each fart became wetter than the last.

"Phew, that last one sounded wet," said Applejack. She looked behind her to see a small brown stain on Rarity's butt. "Heh, you might've soiled yourself a bit."

Rarity giggled.

Applejack touched her gem and let loose with equally wet farts. Soon a brown stain appeared on the back of her shorts as well.

"Oh, almost," said Rarity. She touched her gem. "Though that one did seem to make your rear end a little-"

PPPPPPPBBBBBBBBLLLLLLLLRRRRRRT!

Rarity noisily released a ton of hyperscat into her shorts. She sighed, loving the feeling.

"Phew, that smells awful." Applejack touched her gem, instantly filling her bowels with hyperscat. She grunted and quickly made an equally big mess in her jean shorts.

PPPPBBBBBBBBBRRRRRRRRRLLLLPPPPP!

"Ahhhhhh..."

Rarity could feel Applejack's mess squishing against her back and she squealed in excitement. "Hold on..." She touched her gem, then squealed again as she started to pee.

Twilight and Fluttershy finally finished peeing, having peed straight through Rarity and Applejack's farting and messing.

"Hold on," said Fluttershy. She touched her gem again, and then silently soiled her panties.

Twilight giggled at the feeling of Fluttershy's mess against her rear. She touched her gem and filled her shorts with diarrhea. Fluttershy giggled at this.

Applejack patted Rarity's butt lightly three times with her hand. Rarity could feel it through the mess in her shorts and knew what the signal meant from last time. Rarity stood up, knocking Applejack off her. Applejack fell on her back in the mud.

Rarity lay down facedown next to her and touched her gem to cast a spell on the nearest horse. It walked over to her, sat on her butt, and farted repeatedly.

Applejack immediately rolled around so she was facedown beside Rarity, cast a spell on another horse, and it sat on her messy rear and started to fart.

"Ya know," said Applejack, pausing to touch her gem and then start peeing, "some of your farts were as loud as the horses."

"Why thank you," said Rarity.

Twilight and Fluttershy, meanwhile, were laying on their backs, with two horses peeing on them. Once they were done, the two pee-soaked girls cast another spell, and the horses buried them in a pile of manure.

Twilight had cast a spell on her glasses so that they'd repel all mud, pee, and poop, so she'd be able to enjoy the experience without any visibility problems. Both she and Fluttershy wet and messed themselves again before climbing out of the manure.

Many fun and messy moments later, Fluttershy, Applejack, Rarity, and Twilight sat side by side, covered in mud and poop and smelling very bad. They had all enjoyed this experience and couldn't wait to do it again.

"I'm so glad you're all into this too," said Twilight. She paused to make another mess in her shorts, this time hyperscat. "I thought I was really weird for liking this."

"So did I," said Rarity. "I don't think any of you could be more relieved than I am."

"Oh, I might be," said Fluttershy as she started peeing again.

"I know I'd always play in manure before Twilight and I discovered this place," said Applejack. She touched her gem and released a load of diarrhea into her shorts. "This is even more fun."

"And now we can clean ourselves instantly!" said Twilight. "Ooh, think of all the possibilities!"

"It does make things rather convenient for me." Rarity let out a sloppy wet fart, and giggled, as her shorts felt even dirtier than before.

When they finished their conversation, they stood up, stepped out of the mud field, used their gems so they were completely clean and dry, and headed to a restaurant to get some lunch.
