Here's a '70s clip of a man and "woman" engaged in S&M. 

A man wears a black leather mask and leather, butt-less bodysuit, chained to a barn door by his hands. A "woman" in a dark robe and red corset whips his body, he bites the whip, and licks her leather boots on his hands and knees. 

In the final shots, the man lasciviously licks and sucks the leathered fingers of the woman he is being subservient to.
