Applejack and Rainbow Dash had just gotten married and were on a honeymoon roadtrip. Rainbow Dash was wearing her usual skintight black shorts under a pink and white skirt, and Applejack was wearing jean shorts.

"So Applejack, how about we do some kind of sports competition on our honeymoon?" said Rainbow Dash.

"You're on!" said Applejack. She spit on her right hand while holding the steering wheel with her left hand. Rainbow Dash spit on her hand, and they did a fist bump. They were always ready for a little friendly competition.

Suddenly, both of them got a terrible stomachache.

"Mind if ah stop the car?" said Applejack.

"I was just about to ask you to," said Rainbow Dash with a pained look on her face.

As Applejack pulled over on the side of the road near some bushes, she let out a loud, wet fart.

Rainbow Dash chuckled a bit and accidentally let a louder, wetter fart. Her shorts felt a little wetter, but she felt her butt and was relieved to see she hadn't made a mess.

They ran behind the bushes, farting the whole way. They ran behind the same bush, pulled their shorts down, and started to poop. They didn't feel ashamed at seeing each other with their shorts down, given the relationship they were in.

Rainbow Dash finished after less than a minute, but Applejack didn't stop for another two minutes. Or three. Or five. It started to pile up, and Rainbow Dash stifled a chuckle. Applejack blushed lightly at how long this was going on for.

Finally she stopped. She pulled her shorts back up and looked at the pile of shit she had made on the grass.

Rainbow Dash couldn't hold it anymore and started to laugh. Applejack chuckled nervously, but didn't feel overly embarrassed around Rainbow Dash.

They got back into the car and continued driving. Rainbow Dash's pink panties and Applejack's white panties felt a little dirty, but it didn't show up on their shorts (especially Rainbow Dash's), much to their relief when they checked in the mirror at the motel they stopped at, for they had forgotten to bring any changes of clothes.

The next day, they continued on their trip. It was a long trip, but for most of the day they didn't have to poop. If they had to pee, there was always a gas station or a bush nearby.

Rainbow Dash farted a few times due to having beans for breakfast. Applejack didn't laugh but did feel a bit aroused.

After having a big supper at a restaurant, to which the meat seemed a little undercooked, the athletic tomboys continued on the road, but they were getting tired and there wasn't a city for another few hours.

"Where are we gonna sleep?" said Rainbow Dash. "We've been on the road all day and I'm tired! I don't want to sleep in the car."

"We won't have to," said Applejack. "There's an old abandoned barn in the woods nearby. We can sleep there if it's still standin'."

Applejack parked on the side of the road and they walked 300 meters off the road into the woods, and found the barn, which was still intact and still abandoned. They went into the barn and relaxed for a bit.

Until Applejack let out a loud, wet fart, and that all too familiar feeling hit her.

"Uh-oh!" said Applejack. She looked around the barn for any sign of a bathroom, but there wasn't one. So she ran behind the hay to do her business.

Rainbow Dash was also feeling the effects of the undercooked meal they had eaten, and let out a sloppy wet fart.

Before she could join Applejack behind the hay, Applejack noisily released a ton of hyperscat.

The fart sounds were too much for Rainbow Dash. She started to laugh, and then, with another wet fart, made a big mess in her shorts. She blushed with embarrassment while Applejack's mess continued to pile up under her.

Rainbow walked behind the hay and emptied her shorts beside Applejack. She was relieved that she only had a few seconds' worth of hyperscat rather than minutes like Applejack, as it was still falling from Applejack's butt in torrents. Rainbow Dash chuckled as she pulled her soiled shorts back up.

Finally Applejack was finished, and pulled her shorts back up. There was no toilet paper in the barn and this hyperscat was the kind where Applejack would have to wipe like 10 times.

"Is there a stain on mah shorts?" Applejack turned around so Rainbow Dash could see her butt.

"Yes there is, but it's just a small one. My shorts are definitely dirtier."

Applejack chuckled. "Maybe we should take them off and let them dry a little first."

"Are you thinking what I'm thinking?"

"Ah am."

After sex, they put their clothes back on. Rainbow's shorts felt a little drier but were still dirty and smelled bad. They slept cuddled together, farting a few times before they went to sleep.

The next morning, when they awoke, Applejack let out a sloppy wet fart and felt a small load of poop slide into her underwear. She ran behind the hay again and was able to avoid making a bigger mess in her shorts, though the stain on her butt was now bigger, and her shorts were stinkier.

They hit the road again, confident they would reach their destination today.

"What if someone notices the stain on my behind?" said Applejack.

"I'll tell them you sat in the dirt," said Rainbow Dash. "And if they still notice a smell, I'll tell them I farted. Besides, most of the smell will be coming from me." They laughed.
