Sex Ritual of the Occult (1970)

One of the blondes has a full sleeve tattoo and is jerking off while watching the other two go at it on the bed. The brunette with piercings is deep-throating the other girl, then switches to eating her out in doggy style with the camera right in the action. You see a lot of skin, sweat, and fingering — the lighting’s all red, feels like some spooky sex ritual but not much actual ceremony, just hardcore girl-on-girl. The second blonde gets mounted hard in missionary, then switches to riding the brunette from behind. Camera stays close during oral, wide during fucking — good balance. No dudes, no break — just non-stop lesbian sex with slim and curvy bodies grinding for like ten minutes straight.
