Author's Notes:

Just randomly threw this in and hoping it won't be seen by anyone who isn't following me or hasn't favorited it. I'd been planning this for quite a while. Quality might be inferior and/or repetitive of the previous scat stories.

Again, it's the human world's Twilight.

DO NOT READ unless you REALLY love my stories, or at least my scat ones.

After a big meal at a restaurant, Sunset Shimmer and Twilight Sparkle were going for a hike in the woods. The other girls were busy today, and besides, they wanted to spend some quality time together.

Sunset was wearing a white shirt with pink sleeves and short, fairly tight gray shorts. Twilight was wearing a light blue T-shirt and short, equally tight purple shorts.

They had each drank a carton of milk they got from a vending machine near the restaurant before they made their way to the woods.

They walked along a path for about an hour, having a lively conversation, when suddenly Twilight felt her stomach gurgling. Sunset could feel her stomach cramp.

"Sunset... I'm not feeling so good," said Twilight.

"Me neither," said Sunset.

Then, Twilight accidentally let out a loud wet fart. She blushed and giggled nervously.

"Don't feel ashamed, Twilight," said Sunset. "We all..."

PPPPPPPPPRRRRRT!

Sunset blushed at the sound that had come out of her.

"What in Equestria was in that lunch?"

"I don't think it was the restaurant food," said Twilight. She farted again, and blushed a little. "That milk did taste kind of funny. I think it might have spoiled weeks ago."

"Ugh..." Sunset farted again. "That's not good."

PPPPPPPPPPFFFFFFFT

Twilight released an even longer and wetter fart than before. "We need to get to a bathroom NOW!"

Sunset and Twilight ran back the way they came, farting several times. Their stomachs cramped within a minute, forcing them to walk at a more steady pace.

BBBBBBBRRRRRRRRT

Sunset let out a deeper-pitched fart for about five seconds.

"That might be our best option for relieving some of the pressure," said Sunset.

Twilight let out a sloppy wet fart for about seven seconds.

FFFFFFFFFFRRRRRRRRRT

Twilight immediately felt her butt while Sunset sniffed, the air smelling more foul than their previous farts. The butt of Twilight's shorts felt a little wet, and her underwear felt dirty, but there was no real mess in there yet.

Sunset released an even louder fart that she was sure made her underwear a little dirty as well, but like Twilight there was no mess yet.

As they walked, their farts became wetter and smellier, and soon their need to poop became clear.

Twilight farted again, and had to stop immediately because she nearly soiled herself then and there.

About a half hour into the walk back, Twilight's desperation became unbearable.

"I can't hold it in any longer!" she said. "I'm going behind a tree!"

"So am I," said Sunset.

They ran behind trees on opposite sides of the path. Both girls pulled down their shorts and underwear. Sunset's panties were red, and Twilight's were white, though both had small brown stains on the back.

PPPPPPPLLLLLLLLLLLLLSSSSSSSSSHHHHH

Sunset and Twilight sighed in relief as they released the contents of their bowels on the ground beneath them. It was very loud, but they didn't care, for they had heard each other fart and it was better than messing themselves.

It was very wet though, the kind of poop where you would have to wipe your butt at least ten times after.

Once they had done their business, both girls pulled up their shorts. There was no toilet paper around here, and their underwear felt even dirtier now. As they resumed their walk, they both scratched their butts.

Twilight farted, and giggled nervously.

Under twenty minutes later, they felt the second wave hit.

It started with them getting really gassy again. Sunset and Twilight released a series of boisterous, wet farts, some of which made their underwear even dirtier.

Then, the pressure in their bowels grew to tremendous proportions as they exited the forest into a field.

There was an outhouse on the other side of the field. Sunset and Twilight ran toward the outhouse as fast as they could. Their stomachs cramped, but they didn't care, they were so close.

As soon as they reached the outhouse, Sunset started to open the door, but Twilight shoved her to the ground and tried to get in. Sunset pulled her back and they wasted two valuable minutes desperately fighting over the outhouse.

Then, Twilight let out a very loud and very wet fart, blushing as the back of her shorts got a small brown stain. The girls stopped fighting immediately. This fart smelt worse than any of their other farts since taking a dump the first time.

"I'm sorry, Twilight," said Sunset. "You should go first. From the sound of that fart, you have to go more than I do."

Twilight really wanted relief. But...

"No, you go first," said Twilight. "You reached the door first and I started the fight. I can hold it until then." She wasn't sure of this, but she didn't want her friend to have an accident on her account.

"Well..." PPPPPPPRRRRRRT! "...if you say so." Sunset ran into the outhouse.

Twilight held it as best she could as she heard a series of loud farts inside the outhouse, followed by a loud splashing in the toilet.

Then, an even louder, wetter fart made its way out of Twilight's butt, followed by a few short but equally loud and wet farts. She could feel her underwear get dirtier with each one.

"Uhhhh... I can't... I'm not gonna make it..."

PPPPPPPPPPBBBBBBBBBBBBBLLLLLLFFFFFRRRRRRRRRRT!

Twilight moaned as she released a loud and smelly brown mess into her shorts, which quickly bulged at the back. It was even wetter than the last time, to the point that some of it leaked through her shorts and oozed down her back legs.

The smell reached her nose, and it stank a lot more too. Twilight stood there frozen before Sunset came out of the outhouse.

"I can't believe there's no toilet paper in there either!" said Sunset. "That was even wetter than the last time. I'm gonna need to change my underwear before..."

Her nose picked up the stench of Twilight's accident and she looked in her direction.

"I didn't make it..." Twilight blushed.

PPPPRRRRT

She farted again, and was sure she had added to the mess in her underwear.

"I'm so sorry Twilight," said Sunset. "I knew I should have let you go first."

"No, I insisted you go first when I had to go more badly."

"It's all right, I'll get you cleaned up."

Twilight felt a bit better as she and Sunset walked to Sunset's house.
