an abnormal desire hidden behind a gentle smile... the true identity of the beautiful mother was a perverted woman who confined her son and endlessly performed fellatio and harassment! kanna, who is both a mother and a teacher, confines her son, shuuichi, to the room instead of sending him to school. "you've made it big again... i can't go to school like this," she masturbates and performs fellatio on her own accord. and sometimes she rides her son, shakes her hips violently, and orgasms... is mother an angel or a devil? a psycho-thriller-style ejaculation management suspense that continues infinitely because of family. #classmonitorp
