In a traditional Japanese home, a lonely housewife, hungry for affection, finds herself drawn to her stepson's innocent allure. She watches him secretly, her eyes lingering on his youthful body, her mind filled with taboo thoughts. One evening, she can't resist any longer. She enters his room, her silk robe barely concealing her curves, and offers herself to him, whispering in his ear, "Teach me, teach me how to please you."
