Bahía blanca (1984)

She’s got long brown wavy hair and a slim build, smiling in the sun at the start before things move indoors. Once in the bedroom, she’s on top, riding him slow at first with her hands on his chest, then picking up pace as she bounces down hard. He flips her over and gets her on all fours, pulling her hips back into him while she braces against the headboard. The camera stays tight the whole time — you see every thrust, every shift of her ass, her mouth open in quiet moans. There’s a quick outdoor shot of a beach and a sunset, but most of it’s just them in the room, going from missionary to doggy with no breaks. The lighting’s low, natural, not too dark — good focus on her back arching and his hand gripping her waist.
