Author's Notes:

This one I had the most difficulty with getting it detailed enough since I don't know much about the human Sweet Apple Acres so I did the best I could of humanizing two significant pony moments I could think of.

It was a hot day. Applejack stood under the boiling sun, in a white and green T-shirt and a pair of short, tight jean shorts, for today was a day in which she would be doing a lot of hard work.

First, she had to feed the animals. This didn't take very long. When she was done, she was sweaty and thirsty enough to drink a glass of apple juice.

Next, she and Big Mac were demolishing their old barn, to make way for a new one they were planning to build.

"Ready to smash this barn?" Applejack asked, with a hammer in her hands.

"Eeyup", said Big Mac.

Applejack and Big Mac smashed the barn to pieces. This took quite a while, and when it was done, Applejack was dripping with sweat. She drank three bottles of cider and two bottles of water, then when she was feeling hydrated again, she and Big Mac moved the remains of the barn out of the way.

Now came the part that would take longer - building a new barn. Applejack sang "Raise This Barn" as they were beginning construction. Apple Bloom helped out with this as well.

After they set up the frame of the barn, Applejack drank another bottle of water, two glasses of apple juice, and a bottle of cider. As they resumed construction on the barn, Applejack started to feel a need to pee. She had drank quite a lot. But she held it for now, wanting to get this work done as quickly as possible.

They were about halfway done the barn construction when Apple Bloom said "I gotta go to the bathroom" and ran to the farm outhouse. Applejack and Big Mac kept up the construction until Apple Bloom returned.

Pretty soon, Big Mac ran to the outhouse as well, and returned, having made it just like Apple Bloom. Applejack's need to pee was growing more intense, but she ignored her bathroom needs and kept working.

They took another brief break to get some more drinks. Applejack chugged down three bottles of water, two cans of soda, and two more bottles of cider.

"Don't you have to go to the bathroom by now?" Apple Bloom asked. "You haven't been to the outhouse since we started, and you've been drinkin' a lot."

"Ah can hold it," said Applejack.

They resumed construction on the barn. As they worked, Applejack felt her bladder rapidly filling up by the minute. She had to pee really badly, but she stubbornly refused a bathroom break, determined to finish her work first.

Finally, in the course of several hours, they finished building the barn. Applejack was drenched in sweat, even her outfit, and she drank five bottles of water, three bottles of cider, and one cup each of apple juice and soda.

But their work today was not done, for there were several apple trees that needed picking for making more apple juice, cider, and apple pies.

"Well, time to get at these apple trees," said Applejack. She fidgeted slightly and held herself with one hand.

"AJ, you should really use the bathroom first," said Big Mac.

"Nothin' doin', Big Mac," said Applejack. "I'm gettin' the apple buckin' done first!"

Unlike her pony counterpart, Applejack didn't kick the trees to shake the apples out. She climbed up a ladder and pulled the apples out of the trees. Apple Bloom would hold the buckets as Applejack tossed them into them.

On the third tree, Applejack held herself with one hand as she picked the apples with the other. She was in desperate need of a bathroom, but still refused to delay her work for anything other than drinks.

"Applejack," said Granny Smith, who was walking by to check on how her grandchildren were doing. "You should stop for a bathroom break. I can tell you have to pee like a race horse."

"I'll go when I'm done apple buckin'," said Applejack.

"You're gonna wet your shorts at this rate."

Applejack blushed. "They're already wet with how much I've been sweatin'. And I can hold it."

"If you say so."

Three more trees later, Applejack drank three more bottles of water and four more bottles of cider. Then she returned to picking apples.

Her need to pee was so intense that she kept missing the bucket when throwing the apples into them.

"Applejack, you can't even aim anymore," said Apple Bloom. "You really need to go to the bathroom."

"Ah said ah can hold it!" Applejack didn't mean to sound this annoyed but her bladder was very full.

Once all the apples were out of the tree, Apple Bloom was picking up the apples off the ground and putting them into the bucket. Applejack quickly did the same, holding herself with one hand while throwing the apples into the bucket with the other.

Applejack picked up the ladder to haul it to the next tree, and leaked into her white panties. She whimpered and held herself with both hands, fidgeting in place.

"You all right, sis?" Apple Bloom asked.

"I'm fine, sugarcube," Applejack said. "I just... I just gotta pee somethin' fierce!"

"Then go."

"I..." Before Applejack could decide whether to argue or simply accept that she needed to go to the outhouse...

Sssssssssss...

Applejack stopped fidgeting and trying to hold herself as a loud hissing noise was heard, and she felt a warm wetness spread through her already sweat-soaked shorts. She sighed in relief as strong rivers of pee gushed down her legs, filling her boots to the brim and watering the grass. The relief felt delicious, but it was embarrassing all the same.

"I told you," said Apple Bloom, feeling bad for her older sister despite her stubbornness.

Applejack blushed with embarrassment. How could she have wet herself? Yes, Fluttershy wet herself all the time, but it happened so often that it was expected of her. That almost sounded a little mean in her head, but it was true, though she always took great efforts to avoid being insensitive about it and would do her best to cheer Fluttershy up, if Rainbow, Pinkie, or Rarity didn't do it first. Pinkie sometimes wet herself too, but she was Pinkie, she almost didn't count. Sunset had also wet herself twice, based on what she had said after Fluttershy's first accident after Sunset became their friend, but any pony would have done the same in her situation.

The answer hit Applejack quickly. It was her own fault. She brought it on herself by being too stubborn to use the bathroom when she clearly needed to go. She let out a sigh of shame as she continued to pee in her shorts full force.

She peed for a very long time due to everything she had drank. Granny Smith got a view of Applejack as she wet herself. "Poor Applejack," she said sympathetically. "You should've gone to the outhouse."

"Yep, I should have," said Applejack, still peeing. "I'll remember that in the future."

When Applejack finished peeing, she stood there in her wet shorts. They had been soaked with sweat before, but now they smelled strongly of pee. Her legs were now glistening with more than just sweat.

"Wanna take a shower?" Granny asked.

"I'm only gonna get all sweaty again. I can stay like this till I finish the work. A little pee won't hurt me there. But if I have to go again, I'll use the outhouse this time, even though I'm already wet."

Granny nodded in approval. Applejack, gradually recovering from the embarrassment of her accident, moved her ladder towards another tree. Apple Bloom was right there with her with the buckets, and didn't bring up the wetting for the remainder of the day. Part of her thought it was a little funny, and part of her thought she kind of had it coming for being so stubborn. But she loved her sister a lot, no matter how many times she wet herself.

Applejack finished the apple bucking in her pee-soaked shorts, and then, her work done for the day, took a relaxing shower and exited the bathroom in a dry shirt and her usual jean skirt. She was confident she could put this whole incident behind her, except that she wouldn't repeat the same mistake again.
