Taboo V: The Secret (1986)

Voluptuous Colleen Brennan plays Mary, a split-personality who is a Madonna by day, but at night, her other self surfaces as a seductress who drives her son, Shone, wild with desire. Again, Kirdy Stevens masterfully penetrates the decadent world of incestuous secrets as no other adult film director can. As the intricate and sordid story unravels, the web of carnality slowly and sensually envelopes all whose raw passions reveal their innermost secrets from the voracious Amber Lynn and her black paramour Jonathan Younger to hot blooded newcomer Porsche Lynn, to the daughter, Karen Summer, Kevin James as Junior, Shone Taylor as the son, wild and kinky Lorrie Lovett and Jamie Gillis in his continuing role as the psychologist.
