Three years into their marriage, Rika has not had sex with her husband for over a year, and is feeling frustrated. One day, her husband brings his boss, Akishima, to the house. When Akishima confesses his feelings to Rika, a sweet tingling sensation she hasn't felt in a long time with her husband runs through her body... Later, Rika visits Akishima's house without her husband's knowledge, and unable to lie to her body, she gives in to the pleasure. However, that's not all, Akishima shaves Rika's pubic hair, leaving her completely bald, saying, "It's our secret, just between the two of us."
