Fair warning: When they get to the camp, I was sort of rushed to finish it and don't describe anything in detail. This will be a HUGE point of criticism, which is why I was initially not planning on submitting it.

It had been a few days since Applejack and Rarity had learned their shared dirty secrets. Both of them were taking four days off to go camping. They had someone to look after the boutique and the farm while they were gone.

They were going to a campsite farther than Camp Everfree, where they were sure no one would interrupt them.

They drank a big cup of coffee each, and a few glasses of water, as it was a hot summer day and they had woken up damp with sweat, and not peed in the bed this morning. Then they packed their bags.

"Aren't you gonna change into your dress?" said Applejack.

"I'll pack it, but I think I'll wear my smelly outfit for the trip," said Rarity. "There will be no one there but us, and I know you like it." She turned around and farted loudly.

"Nice one, Rares," said Applejack, slapping Rarity's butt playfully.

They packed their bags into Applejack's car, and they hit the road.

As soon as they turned onto the highway heading for the campsite, Rarity farted.

FFFFFFFRRRRRRRRRRT!

Rarity giggled.

Applejack chuckled and let out a louder, deeper-pitched fart.

BBBBRRRRRRRRRRRRRRT!

Rarity let out a longer but equally loud fart. Applejack released three short but loud farts.

Then a boisterous, wet fart made its way out of Rarity's butt.

"Hoo, nelly. Y'all sure you didn't soil yourself?"

Rarity felt her butt. "No I didn't, thank goodness."

They farted for about twenty minutes before they ran out of gas. The inside of the car was really starting to smell, but they liked it so they kept the windows closed.

About ten minutes later, the intense urge to pee hit them. All they had drank this morning had gone through them.

"Applejack... I need to use the bathroom."

"I gotta pee real bad too."

They held it for ten minutes before they suddenly hit a traffic jam.

"You gotta be kiddin' me!" Applejack honked the horn, but the cars wouldn't move.

"I don't know how much longer I can hold it," said Rarity. "If we don't get moving soon, I'm going to pee all over your seat!"

"Here." Applejack put her car in park, got out of the driver's seat while holding herself, and opened the trunk. She picked out two garbage bags and two towels. As Rarity sat with her legs crossed, Applejack set a garbage bag on the seat of her car and set a towel on top of it.

"You can sit on these if you think you ain't gonna make it."

Rarity undid her seat belt and stood up slightly as Applejack placed the garbage bag and towel on her seat. Then Rarity sat back down and buckled up her seat belt.

"Ahhhhhh..." Applejack started to pee. The sound of her stream soaking her shorts could be heard. The towel and garbage bag protected her seat.

"Are you sure no one can see us?" said Rarity.

"They can only see our faces," said Applejack. "It's all right, Rares. Just let it out."

Rarity relaxed and began wetting her skintight shorts. She blushed lightly, but let out a sigh of immense relief. They both enjoyed the warm, wet feeling.

As soon as they finished peeing, the traffic got moving again. Applejack and Rarity laughed as they continued on the road in their wet shorts.

...

They reached their campsite, set up their tent, and packed their coolers inside it, which were full of bottles of cider. Applejack had made sure to pack enough to last them the trip. They also had a case of water bottles, and had mainly brought beans and apples for food.

Once they had finished setting up their campsite, they each took a water bottle and began running down a path. It was a hot day so the sun dried their damp shorts.

"Should we take those towels off the seats?" said Rarity.

"Nah, let's leave 'em there in case we get caught in traffic again."

As soon as they reached the end of the path, they ran back the way they came. They did this until they were tired and dripping with sweat.

After drinking what remained of their water bottles, they looked at each other, admiring how sexy they looked dripping with sweat. They leaned in to hug each other and kiss, in the process smelling each other. Then they pressed their butts against each other and rubbed them a bit.

...

That evening they ate their dinner, consisting of beans cooked over a campfire, with some apples and water, and then they roasted some marshmallows and told ghost stories.

"Here's another one," said Rarity. "It's called 'The Smelly, Farting Lady.' It's about a beautiful girl who acted ladylike most of the time, but on her own or with her girlfriend, she loved to smell bad, and even more, she loved to..."

PPPPPPPFFFFFFFFFFFFRRRRRRRRRRRRRT!

Rarity glanced over at Applejack with a grin. She had been holding this in for all of Applejack's last story.

Applejack let out a loud, deeper-pitched, but slightly shorter fart, sighing of relief.

Rarity let out a few shorter, wet farts. Applejack held it and then unleashed an explosive fart that was longer than Rarity's first fart tonight.

After about half an hour, their farting had subsided, and they were ready to go to bed. Applejack drank four bottles of cider, while Rarity drank two.

"Applejack, darling, you're going to wet your sleeping bag," said Rarity.

"Ah know," said Applejack. Rarity giggled.

They brushed their teeth and got into their sleeping bags, which were right next to each other.

"Good night Rarity," said Applejack.

Rarity farted in response. Applejack chuckled.

...

Rarity woke up at about 2 in the morning. She could tell it was raining hard from the sound of the raindrops hitting the tent. She needed to pee really badly.

At first, she held herself, not wanting to humiliate herself in front of her friends. But then she remembered, Applejack was the only other one there and she didn't have to feel ashamed about doing anything dirty in front of her.

Listening to the sounds of the rain, Rarity stopped trying to hold it and sighed in relief as she peed in her sleeping bag. She loved the wet feeling around her, and the naughtiness of what she was doing. Her shorts were soaked before she finished peeing. She did her best not to moan in pleasure, because Applejack was still sleeping.

A loud fart was heard right beside Rarity. Rarity looked at Applejack, who was still asleep. It seemed Rarity wasn't the only one who farted in her sleep.

Applejack farted again, and then a hissing sound was heard. Though she was still asleep, Applejack had a relaxed look on her face and let out a slight moan of relief. After just over a minute, Applejack finished peeing.

...

At the time, Applejack was dreaming about running through hard rain. She saw Rarity fall into a river, and dove in after her. Applejack held on to Rarity as they fell over a waterfall into a calm lake, with it still pouring rain.

It was then that Applejack felt an intense need to pee. "I gotta go to the bathroom," she said. The rain, lake, and waterfall weren't helping.

"You can go right here," said Rarity. Rarity sighed in relief with a relaxed expression on her face. There was no doubt in her mind what Rarity was doing, though the water didn't seem to get any warmer. So, Applejack let go and started peeing, also sighing of relief. Now the water was getting warmer, and felt wetter too.

She relaxed in the lake with Rarity for some time before sitting at the side of the lake in the rain.

...

Applejack woke up, a little disappointed that her relaxing, romantic moment with Rarity was only a dream. Then she remembered she was camping with her, and they had three more days of fun and quality time together.

The next thing she noticed was that she felt wet. She felt her shorts, and her sleeping bag, and sniffed. The smell of pee was in the air. Applejack sighed in satisfaction.

Her bladder was not quite empty, as the rest of the cider had gone through her. Applejack peed again and waited for Rarity to wake up.

About five minutes later, Rarity woke up. Her bladder also had a bit more in it, though less than Applejack. As she peed, Applejack heard her.

"Good morning, Rarity."

"Good morning Applejack. How are you doing?"

"Wet." Applejack chuckled.

"Me too." Rarity giggled.

They got out of their wet sleeping bags and had breakfast in the sunlight, as the sky had cleared, though the ground was still wet and muddy.

They did their run, on the concrete path, drying themselves in the summer heat. Then they drank some water.

"What now?" said Applejack.

"We should walk through the forest."

"Good idea."

So they started walking along a path in the forest. The dirt spots were still muddy, as the sun hadn't dried them yet.

"Isn't the scenery divine?" said Rarity.

"Yep," said Applejack.

Rarity started to run to turn a corner and see what view awaited her. But she slipped on a slick patch of mud and fell headfirst through a hole in a tree.

The hole was on both sides of the tree, but Rarity's arms were at her sides, inside the hole. She struggled, but couldn't get out.

"Applejack, darling, be a dear and get me out of here?" said Rarity.

Applejack walked over to Rarity and pulled on her legs, but slipped on the mud and fell on her butt.

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

"I'm a bit dirty, but fine." Applejack stood up.

"Maybe try pushing instead?"

Applejack started to push on Rarity's butt. It felt so soft against her hands, and Applejack could smell it over her own smell. She sniffed as she pushed. Rarity's butt smelled like farts, piss, and a year of unwashed sweat.

Rarity also liked the feeling. It made her forget a bit about her situation.

Then she farted loudly in Applejack's face.

"Nice one, Rarity," said Applejack, patting Rarity's butt. Rarity giggled. As Applejack continued to push, Rarity farted again. Applejack sniffed deeply with each fart.

"This ain't workin'," said Applejack after about ten minutes. "I'll go get my geode." She started to walk back to the tent.

"Applejack, do hurry up. I have to pee rather badly."

"Just go in your shorts. It wouldn't be the first time this trip."

She did have a point. As Applejack left, Rarity started to pee in her skintight, stinky shorts. Waterfalls of pee trickled down her legs and onto the mud below her. This was a new sensation to Rarity, who was used to peeing herself while laying down or sitting down. She farted again before she was done peeing.

She waited in her wet shorts for five minutes before Applejack returned with her geode. She put her hand on Rarity's butt and pushed forward.

Rarity slid through the hole, flipped over, and landed butt-first on the muddy ground.

"Thank you Applejack," said Rarity. "If only my shorts didn't get dirty."

"They already smelled real bad and you peed in them so much, they were already dirtier than the mud could get them on its own."

"You're right." Rarity giggled.

Applejack sat down next to Rarity and peed in her dirty, stinky jean shorts. "Sorry for not gettin' my geode sooner. Ah just really liked the feelin' of your behind. And the smell."

Rarity giggled. "I was rather enjoying myself too."

...

Though this event did not repeat during their camping trip, the other events did, and they gave each other butt massages before bed. Applejack's butt was firmer than Rarity's, and they both enjoyed it. They also rubbed each other's stinky feet.

On Day 3, it rained again, and Applejack and Rarity went for their run in the rain, which washed the dirt from the mud off their shorts, but wasn't enough to wash off the smell.

Other than the rain, they didn't swim or use the showers (or deodorant), so when they returned from their trip, they smelled bad. They showered, but only blow dried their outfits, which were damp from peeing on the way back.
