Lonely Wives (1972)

This is a German "sex-report" film about lonely housewives that is similar to, but apparently not an official entry, into the long-running "Hausenfrau-report" series. An oft-naked male reporter decides to do an expose on "sexual widows", housewives who are neglected by their busy husbands, after his interest is piqued by his attractive neighbor quarreling with her husband. The women he "interviews" are attractive but neglected wives.
