DVAJ-642 "Two weeks ago, there was a used sanitary pad in the toilet, so today must be your ovulation day, right?" I was targeted by this habitual voyeuristic sexual harasser teacher and raped on my fertile days. Hizumi Mai.

The shy female student, Mai, is always groped by a sexual harassment teacher and forced to watch videos of her changing clothes and urinating. 'If this gets spread around, you'll be in trouble, right?' From that day on, the abuse went beyond sexual harassment. Mai was threatened into deep-throating, and her vagina was brutally penetrated with selfish thrusts. Unable to confide in anyone, Mai could only endure it. However, a used sanitary napkin she had discarded was retrieved, and her ovulation day was identified. Despite being terrified of pregnancy, Mai's body was relentlessly trained to be highly sensitive. In the end, Mai faced the pinnacle of despair.
