Suburban Satanist (1974)

Dark, moody lighting sets the tone for this group scene. Three athletic white guys in their 20s stand around, all built with defined muscles, before things get going. A short, dark-haired guy in his 30s leans over a white brunette on a couch, getting her in the mood. Later, a blonde and a brunette join in, both slim and in their 20s, posing with the guys on stage under spotlights. Another scene shifts to a bedroom where a dark-haired guy lounges on the bed while a brunette sits at a table, warming up for what’s next. No hard action yet, but the setup looks promising for some group play.
