True Blue (1989)

The guy’s got short dark hair and a tight, muscular build — you see him up close in low light, clearly turned on. She’s a slim blonde with long hair, pale skin, and small tits, moving from blowjob to being bent over on the bed. They start with her sucking him, head bobbing as he strokes her hair. Then it flips to doggy — she’s on all fours, back arched, taking deep thrusts while the camera stays tight on the action. The lighting stays dim throughout, but the close-ups keep the details sharp, especially when he’s gripping her hips. No extras, no switching — just straight fucking with a calm, private vibe.
