45-year-old housewife Maiko Sonomura lives with her husband of 18 years and their son, who will soon take his university entrance exams. Now in her prime, Maiko boasts a voluptuous, full-figured milf body that's utterly irresistible. Once enjoying sex twice a week, the gap between her and her husband's libido has steadily widened, leaving her increasingly unsatisfied. Even those two times a week depend mostly on her initiating—her husband reluctantly complies, as if out of obligation, fueling her growing frustration. The quality of their intimacy has declined, and she longs to fully experience the pleasures of being a mature, curvaceous woman in her forties. Tonight, she gives in completely to her desires, seeking pleasure without restraint. Through passionate encounters with her favorite male performers, Maiko frees both her mind and body, discovering thrilling new sensations in this debut work from Mature JAPAN—Supreme!! Housewife's First Nude AV Documentary.
