can anyone identify source of this vintage facial set?

I saw one of these pictures posted years ago in a pro-porn book as part of a sample of vintage porn, presumably from a magazine. The second one I saw just online just a few weeks ago, looks like the same set. If anyone has seen other pictures in this series, or knows the source, let me know. This is one of the first facial pics I ever saw, pre-internet, and still one of my favorites because of the contrast between the forceful strength of the dick grip and the passive acceptance on the woman's face, as well as the perfect lip drip.

A closer look at the book that reprinted the first picture suggests that the source is "Lusty Black Meat," Gourmet Editions, 1985. Unfortunately I can find *no* information about this online, even after specifically searching several sites that archive vintage porn magazines, except that it was apparently one of hundreds of sources for the Meese report on pornography. And I'm slightly uncertain about the source, as neither person in the photo is obviously black (they might be mixed, of course; only a more complete photo set could confirm this). If anyone knows where to find a copy of this, or could even confirm this source, let me know.
