Working as a private tutor, my assignment is a private house where a widow and her daughter, who is preparing for entrance exams, live. The deceased husband was a renowned photographer. Influenced by her father, the daughter dreams of becoming a photographer herself, but the mother does not wish for her to follow that path, hoping instead for her daughter to lead an ordinary life. This has caused friction, and recently the daughter has been avoiding conversations with her mother. After finishing a usual lesson, I head toward the entrance, only to notice the mother isn't there to see me off—something unusual, as she always waits by the door. I notice the door to the adjacent room slightly ajar. Although I never intended to intrude, I end up peeking inside. There, I see the mother sitting on the bed, masturbating her own clitoris. I've unintentionally witnessed something I shouldn't have. Shocked, my mind goes blank and my body freezes. The mother notices me, silently takes my hand, and gently pulls me into the room. From that moment on, she begins using me as an outlet to release her pent-up sexual desire, maternal instincts, and protective urges.
