When 23-year-old Anna Hirose discovers that her younger brother has been secretly masturbating to her used panties, she decides to take control of the situation. Instead of confronting him, she begins deliberately showing him her more seductive and perverted side, gradually escalating her teasing with each encounter.

Eventually, she openly admits she knows about his desires and promises, as his big sister, to take full responsibility for his sexual curiosity. She offers to let him do anything he wants with her—except actual vaginal sex. As his requests become increasingly dirty and extreme, Anna remains committed to her word, embracing her role and allowing things to go further each time.
