Housewife Miki remarried with a new husband and started a new life with her son Junpei. Junpei became very close to his stepfather, almost like they were blood-related father and son. However, this closeness led the husband to teach Junpei extreme sexual knowledge. Concerned about Junpei's future, Miki tried to secretly provide him with proper sex education on her own. She taught him how to kiss, the structure of female genitalia, and even insertion... Using her voluptuous body and large breasts without reservation, she taught her son loving sex.
