This image is associated with the marketing material for a 1985 California Star Productions bondage and fetish movie called Master Control. A knowledgeable fan-review at that IMDB link provides the best available movie synopsis:

This effort by Jason Whitman manages to get some of his lesser-known stars, Lana Ryan and Toni Stern, normally used for magazines and loops, into a talkie, as well as featuring regulars Georgia van Helsing and Sharon Montgomery, star of the legendary loop, Sign!, found in Bondage Classics 10.

GvH (Dr. Wier) is a mad scientist in competition with a Dr. Edwards to develop a mind-control device that reduces a person to someone without a mind of their own, open to any suggestion given by a controller following the sound of the password: P***y, pretty, p***y. What all that has to do with roughie bondage might not be clear, but Whitman quickly clears it up for us.

Montgomery (Sally), who wears only thigh-high boots and a leather waist-cincher throughout the picture, is Dr. Wier’s test subject. The machine works. The maid, Tammy Twitchell (Lana Ryan), gets snoopy and discovers Sally standing, uncomprehending, in a spread-eagle pose, but is discovered herself by Dr. Wier and becomes similarly strung up wearing not much. Tammy’s friend Kate (Toni Stern) shows up looking for Tammy and, wouldn’t you know, she ends up helpless in her skimpy undies, too. There’s whipping mixed in liberally, because that’s just how it goes in the Wier laboratory. After a while of all that, Dr. Edwards shows up and rescues everyone, letting them give Dr. Wier a taste of her own medicine.

The name of director Jason Whitman mentioned above is but one of several aliases for the notorious bondage director perhaps more often known as John Blakemore. This Bondage Blog link features information and links to interviews with him.

Another image of the model Sharon Montgomery in the leather waist cincher and electroplay mind-control gear may be found on the cover art currently in use at the video-on-demand service where Master Control may be streamed for viewing (as a pay service, although substantial free minutes are advertised as being available):

Some small free scene preview thumbnails are also available at that link. This image from the production (perhaps part of a related bondage magazine black-and-white photoset) was found here:
