Her son Kenta has caused a scandal. When his homeroom teacher comes to meet with her, Nao, his stepmother, pleads with him, saying, "It's all my fault. Please don't expel him." To her disbelief, the homeroom teacher offers to cover up the scandal, and in exchange, he asks her to provide sexual service. Nao reluctantly accepts the request and takes the teacher's hard cock into her mouth, but the whole thing is seen by Kenta's bad friend, Kojima. "What were the teacher and my aunt doing? I wonder if I should tell Kenta and the uncle everything (lol)." Nao's life has gone awry since she married her husband and has a child, and her days as a slave to pleasure have begun.
