As I note in the Trivia listing for this meretricious video, "The Millionaire's Wife" is not a feature film from porn's classic era as represented by its DVD packaging, but merely a worthless collection of five random sex scenes cleverly marketed to defraud the porn audience.
The shot-on-video ones are particularly worthless, while the filmed segments are probably recycled from some vintage Swedish Erotica series, given that superstars like Seka and Desiree Cousteau (paired with John Holmes here) wear the trademark scarves of SE fame. Best scene is Rhoda Jo Petty nude in an outdoor pool before a Black stud comes over to service her and provide IR content.
Avoid if you value your money.
