Naughty Nymphs (1987)

A slim blonde with long legs is on top, riding a muscular guy on a couch in the living room. You can see a bookshelf behind them, dim lighting like it’s late night. She grinds slow at first, then picks up pace, bouncing hard while he watches her tits shake. Switches to a brunette who takes over in doggy style in the bedroom — she’s got thick thighs and leans forward so he can grab her ass. He finishes with a blowjob, her mouth full, head moving back and forth under the sheets. Camera stays wide most of the time, no quick cuts, lets you watch the whole thing play out.
