From housewives to elderly mature women, and even older ladies! This series captures the real sex lives of wives who enjoy "naked" sex with men other than their husbands. Volume 73 features three women: Mayuko Okamura (45), a voluptuous H-cup housewife who has only known two men; Shimi San (50), a reserved wife whose demure reactions create intense eroticism; and Mika San (38), a small-breasted housewife with a 1960s idol face, picked up on the street.
