There are many dramas happening under every roof in the world. This work includes four stories that focus on the precarious relationship between stepmothers and their sons. There is a wide variety of family stories that should not be made public, such as a mother who has an affair with her husband, a son who witnesses his stepmother and grandfather having sex, a son who sees his stepmother masturbating, and a son who begs for his stepmother's body for unavoidable reasons. This is a work that will tickle your lustful Kokoro.
