52-year-old Miyuki Takamatsu. Married to her husband for 25 years, with two children now independent, she currently enjoys a quiet life as an empty nester. Yet, there's something she's always wondered about. Watching TV and seeing how much pleasure others seem to derive from sex, she feels a quiet regret—she's only ever been with her husband. She's especially curious about orgasm, completely unfamiliar with the sensation of climaxing, and deeply intrigued by the experience. A married woman just beginning to awaken to her sexuality, Miyuki embraces her first time with overwhelming passion, making love with an intense, storm-like eroticism. Her innocence, sincerity, and anticipation of new sensations are the heart of this powerful debut documentary.
