9 Lives of a Wet Pussy (1976)

Pauline is a wealthy and married New York heiress who embarks on a series of sexual encounters with various people. She keeps in close contact with Gypsy, a tarot reader whom Pauline writes letters describing in minute detail about her conquests from seducing a French stable boy, to having sex with a gas station attendant, to a visiting Nigerian princess with a past, and to a fantasy lover, which apparently stems from her past involving a flashback sequence showing Pauline's young grand mother and younger sister taking a verse from the bible a little too far and seducing their own father.
