Introduction：Unbeknownst to her brother, her younger sister, Akane, has grown into an adult, learned nasty things, and brought a middle-aged man older than her brother home. I think that my brother is absent and I work hard with a middle-aged man in my room. My brother pretending to be absent looks into my sister's room and erects after seeing sexual intercourse with a middle-aged man. What is the action taken by my sister, Akane, on the condition that her brother, who was peeking, shut her mouth?
