Fucky Dancing (1988)

Caroline, an undersexed wife, goes with her dance teacher (and his giant cock). Her younger cousin Emmanuel watches this and masturbates intensely. Caroline feels Emmanuel's mercy and comfort through her tongue and vibrator. Meanwhile, her husband Klaus goes out with the great Black Beauty Melissa. How it all finds a happy ending, you will see in this hard-hitting action movie, in which anal sex is not frowned upon.
