As Katlyn returned, she found that most of the people that were there were gone, and that the girl who was previously at the back of the line was now near the front. That's...slightly disappointing. Still, there is the one girl left. Taking a closer look at the girl, she saw the her looking at her phone in disinterest as if she wasn't in any hurry. Heck, if her bloated stomach was any indicator she was just gassy. That should have an interesting effect. Taking aim, Katlyn fired a concentrated beam at the girl. The girl jerked a bit, but immediately responded with leaning forward in pain and releasing a practical whirlwind from her butt, knocking down the people behind her. As as it did with Katlyn, the girl started to expand. However, Katlyn made sure to hold the beam long enough so that the girl was far fatter than her.

She had just catapulted a small bowel movement with almost the same power as a rifle. She looked absolutely horrified, and so did everyone around her. People were then trying to get as much distance between them and the balloon girl as possible all while said girl fell to her knees heavily and began sobbing. The area was clear save for Katlyn, the girl and the girl's massive ear shattering farts. Katlyn decided to...
