DLEE-823 JD dormitory, simultaneous abdominal pain, panic leak

A group of modern young people from different hometowns gather in a certain women's dormitory. While they'd all like to live at their own pace under the same roof, dorm life isn't always that easy. By strictly adhering to wake-up, bedtime, and meal times, their bowel movements gradually become synchronized, and they end up running into each other in the one shared bathroom. When they have the time, they're kind enough to share... but this time, it was too much. Almost simultaneously, they're hit with intense stomach pains and a feverish urge to defecate. The girls rush to the bathroom, desperately trying to block their anal holes that feel like they're about to erupt. Like a spider's thread hanging in hell, they push and shove, vying for the one toilet, screaming and yelling in anguish. The spider's thread snaps instantly, and everyone falls into hell. Their post-bath panties, their sleep-only panties, their special-time panties... all get mercilessly soiled. The feces of those who had forgotten mercy gave off a foul smell inside each of their panties.
