This is from a 1968 film, The Satanist. The women with the vaseline (?) is Pat Barrington, the other one is I think Bambi Allen, but not 100percent certain. No cast list on the film itself. These B&W films from the 60s are often mocked, but tbh I think they are often a great deal more genuinely erotic than most porn, except for the great Golden Age films.
