Connie and Floyd (1971)

Connie is the first one on her back, wearing nothing, slim with dark hair and a few piercings, getting into it with Floyd, a muscular black guy with tattoos and a shaved head. He’s between her legs going down on her while she sucks him off — full 69 action, both of them working hard, tongues and lips moving nonstop. The camera stays tight on their faces and groins, capturing every moment of suction and flicking, especially when she deep throats him with her hand pumping the base. Later, Floyd steps into the shower alone, jerking off under the water, stroking himself slow at first then faster, flexing his arms and chest as he finishes. The whole thing has a raw, unfiltered feel — no music, just natural sounds and unscripted moans. You get a good look at their bodies throughout, especially her small natural tits and his thick thighs when they’re moving in bed.
