Public health doctor Rui is a beautiful teacher who is popular with students. However, in private, she was taught by her masochistic husband and became an S woman every night, to the point of doing her husband's anal. One day, she receives a horny consultation from a male student who has become interested in anal at school, and she gently teaches him and captivates him. She invites a completely absorbed student to her house for an extracurricular lesson that is not good.
