Lately, my son has been staring at my body... The fifty-something stepmother, Yumi Anno, who is troubled by this, consults with her son's homeroom teacher. However, the teacher sees that the cause of the strained parent-child relationship lies in Yumi's sexual frustration and allure, and forcefully seduces her into a secret physical relationship. The son, who witnesses their tryst, becomes enraged and pushes over Yumi, whose beautiful body belies her age, engaging in forbidden mother-son intercourse for pleasure. Despite ejaculating inside, his youthful penis quickly revives and repeatedly violates Yumi, bringing her to orgasm.
