Before Katlyn could think to aim at anyone, a thought occurred to her. She could see it worked on herself, so why not go further with it? Therefore, she could have even better understanding of it first hand. Plus, she was morbidly curious. What happens when one is hit with a concentrated beam? Katlyn found a bit more secluded area before trying anything, though (she already humiliated herself enough). ow that she was alone, she was less hesitant to try out the beam on herself. She aimed it at her stomach, and then held the trigger. The initial shock was now a full on vibrating sensation in her stomach and bowels as she felt the feeling of poop being pushed out her ass into her pants. However, another sensation occurred that she didn't expect, and that was her body rapidly expanding. When her shirt rode up her now full on gut, she stopped the beam immediately. Her pants were tight and filled with poop, and her ass now felt far fuller than before. She looked down at her gut and touched it with trepidation, it jiggling at the touch.
"Did I...just get fat?" She asked herself. Looking down at the rest of her body and too-tight clothes, she could see she indeed became fat. That was...certainly an interesting side effect that she wasn't sure how to fully react to yet. This was interrupted by the feeling of her pants getting yet tighter, and she came to realize she was still pooping. She touched her butt, feeling her pants still expand as solid waste exited her. Finally, it came to a stop. However, something still felt off. A small bletch left her mouth, much to her surprise, as she discovered she was feeling bloated. A small but audible fart escaped her, much to her embarrassment. What the hell happened to her? After another moment, she realized she had another sensation remain: the feeling of needing to poop still remained, as well as the feeling of a full bowel. Given that her pants were both ruined and already filled with poop, Katlyn decided to just push out the remaining waste. This time it was accompanied by a series of farts that just made the experience all the more humiliating. She continued to push out logs and farts for a number of minutes before she realized she wasn't gaining any relief. Suddenly, it hit her: she could now poop at will. The poop was never ending, and so was the gas she now had. She looked down at the gun; it made her fat, and with the added (permanent) ability to poop and fart on command. She glared at the gun bitterly. Yeah, now she knew, but she was also permanently affected by it too. She didn't gain too much weight, sure, but still it was enough to put her past the fat threshold. She'd have to worry about it later, though. Right now, she just wanted to fuck up someone else. Taking a quick detour to change clothing to something that fit and wasn't filled with poop, Katlyn returned to the line. The gurgling in her now sizable belly made her all too aware of the rising need of her back quarters, releasing a loud fart for a semblance of relief. It was humiliating, and now she wanted to push that onto someone else.
