A lewd wife named Airi, 28, whose youthful body has not yet borne children, finds herself unsatisfied with sex only twice a week with her husband. During her husband's business trips, she indulges in compensated dating to release her pent-up desires. Though slightly nervous at first about letting another man touch her body—something she's never allowed since marrying—her tension quickly vanishes once sex begins. She transforms into a lustful woman, moaning boldly, losing control, and thrashing wildly. This passionate performance becomes a thrilling new experience for her.
