43-year-old Rika is a part-time housewife living in Sakuradai. Her son is a 17-year-old high school student, and she has been married for 20 years to a truck driver who is one year older than her. Her husband returns home only two or three days a month, and she can't reach him by phone during work hours. Under these circumstances, her emotional and physical connection with her lover feels deeper, making her crave affection and intimacy. She applied to participate in order to repay money she borrowed from her affair partner, who is her supervisor at work.

However, she enjoys great sexual compatibility with her boss, meeting for sex twice a month. Her body features voluptuous, motherly extra-large breasts measuring 98cm, with highly sensitive, erect nipples that heighten her pleasure. This work captures the complex emotions of her affair intertwined with her sensual allure.
