Junko Sakuma (60 years old) makes her debut appearance. Having spent 33 years in marriage, she has lived faithfully as a devoted wife. Her husband is known to be unfaithful and fond of chasing women, yet highly skilled in bed—it was he who first introduced her to the pleasures of sex. Her reason for entering the AV industry stems from growing resentment toward her husband's infidelity, leading her to decide on taking revenge by doing this herself. Perhaps due to it being her first time, she appears visibly nervous throughout, her sincerity and innocence clearly evident.
