Bullied student Yuki is sexually mistreated by male classmates every day. Once again, in the classroom, her panties are soaked through with a water gun and she is played with using mops and toys. After being labeled the class pervert, the abuse intensifies. While unconscious in the infirmary after taking medicine, she is molested by her teacher and raped with creampie. Returning from swimming class, her clothes are hidden, forcing her to attend lessons in her school swimsuit. This leads to a 20-consecutive creampie assault involving the entire class.
