Inside Marilyn Chambers (1975)

Marilyn Chambers is on the bed with a slim blonde woman in a dimly lit bedroom, both fully naked and ready. They start with a long 69 position—Marilyn going down on the blonde while getting her own pussy eaten, tongues deep in action. The camera stays close, catching every detail of Marilyn’s long brunette hair brushing against pale skin as she switches to a hard, deep-throat blowjob. The blonde rides Marilyn’s face later, grinding slow and grinding hard, showing off her curvy waist and perky tits. They kiss intensely at one point, switching scenes briefly to a couch, but most of the action stays in the bedroom. The whole thing feels personal, like a hidden cam session between two women who know exactly what they want.
