Red Vibe Diaries: Object of Desire (1997)

Stacy Valentine is the pampered but bored hausfrau of Tony Tedeschi. Stacy's sexual imagination is as wild and vibrant as her life is staid and stifling. As we meet her she is fantasizing a wicked back-door sex bout between the salesgirl and her customer in an adult bookstore. Eventually, Stacy discovers the many pleasures of lovemaking for big dollars as she hooks up with a pricey escort service and warms the sheets of men willing and able to pay for her company.
