Kazoku: Haha to Shimai no Kyousei 6

Otoha, a stepmother, finds herself in a compromising situation with her stepson. He touches and massages her intimately without regard for her feelings, while she, although concerned, does not oppose him. At work, Otoha appears as a professional and authoritative woman, giving orders to her subordinates. However, in private, she displays lascivious behavior with her stepson during a lunch alone. This relationship has deeply affected her sanity and morality as a maternal figure.
