Hot Sisters (1975)
The girl’s got short dark hair, slim frame, and moves with confidence — she’s on top first, riding him slow in bed, grinding down deep. He’s muscular, beard, curly dark hair, just lying back taking it, hands on her hips pulling her down harder. They switch to doggy — she’s bent over, ass up, he’s behind her slamming it, camera close on the slap and stretch. Kissing shots are raw, no fake crap, tongues in, messy. Later he jerks off all over her back, cumshot thick and hits hard. Lighting’s dim but the close-ups get every detail, especially her face during throat blowjob.
