Dr. Ruth Westheimer became an unlikely pop culture sensation in the 1980s with her exuberant sex advice radio show. Caballero riffed on her success with the 1986 porn parody Dr. Truth’s Great Sex. Where Dr. Ruth was short, chubby and grandmotherly, Dr. Truth was a sultry babe played by pornstar Kimberly Carson.
The XXX version involved unorthodox treatment methods. “Dr. Truth is waiting for you to join in the most daringly uninhibited and physically arousing sex sessions ever. Her therapy sends you off into a world of unsurpassed lust and ecstasy. Her advice is pure unadultered vice as she personally demonstrates every sex act known to man and woman.”
Dr. Truth’s Great Sex also starred Bunny Bleu, Keisha, Sandy Summers, Sheena Horne and Sherry Evans.
In 1999, a BDSM studio called Sunshine Films released Dr. Ruthless. The back cover blurb explains, “Dr. Ruthless, America’s kinkiest sexual researcher, and her faithful assistant Mongo have enticed four apparently innocent college coeds into their laboratory!” Front cover tagline: “Her RX for sexcess is punishment most severe!”
