Bedroom Bondage (1994)

It begins as a routine day in the home of Mistress Tara; she is lounging about the living room with her slavegirls, Jennifer and Beth. The phone rings. She plays it cool during the brief conversation, but, upon hanging up, her excitement is betrayed. A new girl is coming! Denise has at long last agreed to try a period of sexual slavery.
What's to become of the sensuous session of boudoir bondage she has been promised for that evening, asks sweet young Beth. No problem, laughs Tara, hauling out rope and subjecting the soon-screaming girl to a strange torture party that includes finger-licking and toe sucking! The weirdly lewd treatment satisfies even the masochistic Beth.
