My stepmother, in her fifties, was assaulted by my homeroom teacher. She secretly entered into a contract with her adolescent son, who knew about their adult affairs, for sexual intercourse and climax. (Yumi Anno, CEAD-043)

Recently, my son keeps staring at my body... Embracing this troubled woman in her fifties, Yumi Anno, I went to her son's mentor for advice. However, due to the strained mother-son relationship, Yumi, who constantly exudes feminine allure and is sexually frustrated, saw through her mentor's forceful persuasion to develop a secret, lustful relationship with him. Witnessing their secret meeting, my son was enraged and pushed aside Yumi's beautiful body, which belies her fifties, engaging in forbidden, pleasurable intercourse.
