Three female students who could only get accepted into a delinquent boys' school with extremely low academic standards. Forced by school rules to cut their hair short, they are required to wear shirts and pants as their uniform. Their classmates are crude and unintelligent, making the girls targets for relentless bullying. One trial after another befalls them. The first trial occurs on May 22nd—since there are only male-only restrooms, they have no choice but to use one, only to be ambushed by boys, verbally abused, and ultimately subjected to a non-consensual creampie gang rape. The second trial comes on May 31st, during gym class changing time, when they are sexually assaulted under the pretense of a "body inspection." The boys mock, "Guys change together in the same place, right? wwww," stripping them half-naked and turning them into bullying targets. A teacher discovers the scene but deliberately ignores it. No one comes to their aid. The third trial happens on June 8th in the library, where they are forced to deepthroat every boy until all have cum, saliva dripping as their throats are repeatedly pounded like fleshlights. The fourth trial on June 15th sees the nurse's office turned into a gangbang room, where the boys freely use the girls' bodies without interruption. From this point, their resistance begins to fade. The fifth trial on July 1st finds them no longer in the nurse's office but in a classroom after school, where an orgy takes place. Though still pretending to resist, their defiance weakens, and they increasingly submit, gradually brainwashed into obedient sex pets. The three unfortunate, flat-chested girls, newly enrolled in this hellish school, are fated to become the class's shared cumdumpsters.
