A busty H-cup housewife, for the sake of her childless husband, has an affair with a male college student while working at a convenience store. The couple engages in a frenzied, three-times-a-week sexual encounter, with the man ejaculating 20 times every time. (MIDV-625 by Nakayama Fumika)

Married for five years with a smooth sex life, Nakayama Aya started working three times a week at a convenience store seeking excitement. Unlike her husband, who had no desire to have children, she was attracted to the gentle treatment she received from a young college student working there... In the store, in the backyard, in the office, and at the man's house... they had intense sexual encounters multiple times. Aya's voluptuous body was too sexy... The two made love wildly, ejaculating 20 times.
