Fireworks (1981)

Close-up of a woman giving a blowjob — she’s got short, light hair and dark eye makeup, wearing nothing but dim light outlining her slim frame. The guy on the bed is muscular with short dark hair, clearly into it, hands on her head as she goes deep. Later, a different couple appears in the same bedroom — a brunette woman with long dark hair on top of a guy with a tattoo, moving slowly in missionary, both half-naked under crumpled sheets. Then it cuts outside to two older women, one blonde with long hair, the other with short grey hair, both white, walking side by side down a residential street in daylight. Before the end, there’s a wide shot of five white guys in a living room — all in their 20s and 30s, short hair, average build, standing stiffly in front of a sofa with plants and a clock on the wall. The scene doesn’t show penetration but lingers on skin, positioning, and intimate contact with a voyeuristic feel.
