One day, Monaka, a gloomy transfer student, pees during class. Her shy personality prevents her from saying "I want to go to the bathroom," and she can't hold it in. Her classmates tease her about her peeing, and she doesn't know what to do, so she just laughs. Her irritated appearance only adds fuel to the fire, and this incident leads to Monaka being raped not only by her classmates but also by her teacher. Forced to drink urine, piss splashed on her, and reverse pee with hard deep throating. Monaka leaves her lunch, and is given stew mess, milk enema, and a massive squirt of juice! Unreasonable selfish desires and sexual corporal punishment. Days of gang rape of her throat and pussy. Monaka, who is bullied at heart, has become the class's sex slave committee member.
