Crazy vintage scene with John Holmes and Carla Crabbe
A very obscure 1970's California XXX flick about a large gathering of people (all strangers to each other) brought together by a hippie loon at a big ranch-chic house as an experiment in free lovemaking. All are given "a mild aphrodisiac" and swap off with each other in any combination that strikes their addled fancy in the home's many groovy rooms.
