Maternal and child mating [Kusatsuji]

Ten years ago, Shihori divorced her husband. Her husband took her parents' rights, and Shihori and Shosho were separated once. As a result, they began to live together again during the period of their enrollment in Confucianism. Shihori, 'I don't want to let go of honors anymore,' became friends with Shosho more than necessary from such a thought, and since then the world that he had lived in was built within his mother and two children. Well, maybe it was only a matter of time before the two had physical relations.
