The Holy Mountain (1973)
The scene starts in what looks like an art studio, with paint supplies and costumes scattered around. Two slim white brunettes — one with long straight hair, the other with tight curls — are the main focus. A guy in his 30s with long, messy hair is naked on a couch, jerking off while watching them undress. They take turns blowing him, then switch to riding him in a slow, grinding motion — close-up shots show deep eye contact and lazy thrusting. After a few minutes, it shifts to doggy style against a costume rack, hard and rough with lots of visible slap. The guy finishes on her back, semen dripping down her spine. Camera work is wide and natural, mostly static shots with good lighting that keeps everything in frame without cutting to fake angles.
