Donna Particolare (1981)

Blonde girl with long hair and a slim build is making out with a brunette guy who’s muscular and has short brown hair. They’re on a bed in a dimly lit bedroom, close up so you can see their tongues and how wet the kissing gets. The camera stays tight during the foreplay, then pulls back just enough to show her riding him slow at first, then picking up pace. She leans forward so her tits press against his chest, both of them grinding hard. Later they switch to missionary with her legs up, giving clear shots of deep penetration and how stretched she looks. No cumshot shown in these frames, just continuous fucking with natural moans and body movement that feels unscripted.
