Titanic Desperation

~Commissioned by anonymous~

~And also I forgot to mention in the title but this story includes peeing as well~

A few years ago, humanity had received a grim reminder of the vulnerability of its existence. When the Colossal Titan appeared, standing higher than the fortifications supposed to protect the last of human civilization, everyone remembered the horrors waiting outside of the walls surrounding them. Still, some humans chose to fight back, and joined the elite forces meant to oppose the Titans.

A few of those humans had left on a scouting mission, one of the last missions they needed to do to complete their training. The mission was an all female mission, as the higher ups had decided that it would be beneficial for the girls to learn how to live in close proximity with each other were they to venture outside of the walls. The training expedition was led by the veteran Titan Killer Petra Rall, and consisted of six other soldiers in training.

The group had stopped for the night, camping out under the canopy of stars above them. The girls all lay in sleeping bags, arranged around what used to be a campfire, but now was a pile of charred logs and glowing embers. Sasha Braus, a girl with light brown eyes and hair, lay awake on her side, listening to her companions around her breathe heavily and slowly.

"Um... is anyone awake?" she asked tentatively, her brown eyes jumping around the forms of the girls around her.

Someone let out a loud snore. Sasha waited for a reply, and then grimaced, pulling her knees a little to her chest. Petra had given her the opportunity to cook that night, and Sasha had enthusiastically cooked a stew. She had eaten five helpings of her cooking, and could've eaten more. But now she was starting to regret that. Gurgles and rumbles came from her stomach, and she felt bubbles of air moving through her body, gradually making their way towards her butt. She had to fart, and she had to do it badly. But she didn't want people making fun of her again.

"No one's awake?" she asked hopefully after a silence, her eyes lighting up. Maybe she'd be able to let out just one...

"Sasha, is that you?" a voice said, coming from above Sasha. She recognized Krista's voice.

Sasha pouted, pressing her lips together. The last person she wanted to hear the gas building up inside of her was that adorable blue-eyed blonde. It would be too embarrassing for Krista, someone so pretty and like-able, to hear the disgusting things Sasha's body was currently producing. But with every passing second, Sasha's need to fart just became worse and worse. She finally squeezed her eyes shut, silently cursing to herself.

"Hey, Krista..." Sasha said after a moment. Her body gurgled, more and more gas bubbling towards her rear end. She grunted with discomfort before continuing. "...I know this is really gross, but I... I really have to fart. I'm doing my best to hold it in!"

She heard Krista murmur something. She frowned, moving her head to look in the blonde's direction.

"What?" she said.

"I said I..." Krista hesitated. Her voice sounded small, timid. "...I have to fart too."

Sasha's eyes widened with surprise. Then she grimaced again, wrapping her arms around her stomach. She grunted with effort, trying to hold everything in.

"Sasha," Krista said, "your food was delicious... but... it's making me really gassy."

Sasha heard Krista shift around in her sleeping bag. She looked around at the other girls, biting her lips. The brunette uncomfortably moved her legs, trying to find a way to lessen the pressure she felt inside. Perhaps if she could find a way to make it silent...
