70-year-old Sumire Sawa makes her AV debut. After losing her husband 30 years ago, she faithfully upheld her vow of chastity as per his will, making this her first sexual experience in three decades—a rare background. She insists, "I don't even masturbate," but gradually changes her demeanor when erotic topics arise. When the male actor touches her groin, she is clearly wet, revealing her secretly lustful and sensual side.
