Daughter-in-Law Cheats on Father-in-Law on First Visit

Minami arrives at her husband Satoshi's childhood home for the very first time to meet his family. The atmosphere is thick with unspoken tension; her in-laws seem distant and preoccupied with their own silent arguments. Satoshi attributes the coldness to his father’s frequent drinking habits—an explanation Minami readily accepts. The next morning brings a new dynamic: her father declares he is unwell and asks Minami to stay behind while Satoshi heads out to reconnect with old friends. While savoring a dessert of jelly offered by her father-in-law (FIL), Minami begins to feel an overwhelming wave of drowsiness. When she finally stirs from her nap/doze off state, she discovers she has been thoroughly invaded and pleasured by him without any warning! Because the FIL is recording every moment of their passionate encounter, Minami feels compelled to yield completely to his desires. The situation escalates dramatically when Minami’s mother spots them in action. However, she can do little more than watch as the scene unfolds, because it turns out *she* isn't innocent either—the mother herself is actively cheating! This shocking revelation cements a cycle of infidelity within the family.
