Behind her gentle smile lies a perverse desire... The beautiful mother's true identity is that of a perverted woman who holds her son captive and endlessly harasses him with fellatio! Kanna, who is both a mother and a teacher, keeps her son Shuichi confined to his room and prevents him from going to school. "He's grown it again... he won't be able to go to school like this," she says, selfishly performing oral sex and drinking his semen. Then, at times, she straddles her son and vigorously shakes her hips until he climaxes... Is the mother an angel or a devil?
