Upon uncovering his wife's flagrantly adulterous ways, Jamie Gillis, an esteemed psychiatrist, succumbs to his own sexual desires and proclivities in "Taboo 9". An overall-good, 1991 release from Metro and director Alex DeRenzy, this film loosely ties in with prior installments of the series, both with the non-sex presence of Kay Parker, who reprises her earliest role, and also via dizzying flashbacks to prior material (clips). With the incest themes found in previous episodes largely relegated to the clips, this production focuses heavily upon adultery, with a bit of TS and cross-dressing kink thrown in for good measure, as well. While not up to the same level in terms of both storyline and heat as some of its predecessors, this one is still good and certainly worthy of a watch...particularly for fans of the series.
