Journey of O (1975)

Redhead with long wavy hair is deep on a cock, lips stretched, head bobbing steadily in close-up. The angle keeps it tight, you don’t see the guy — just her mouth working and her hand jerking what she isn’t taking. After a few minutes, a brunette with short curly hair climbs onto the bed, starts grinding against the guy’s thigh while the redhead keeps sucking. They switch — brunette takes over orally, redhead lies back, gets eaten out thoroughly while fingers work her pussy. Later, she’s on all fours, getting pounded hard from behind, camera steady on her slim back and the guy’s thrusts. The lighting stays warm and dim, all skin tones golden, no cuts to nonsense — just sex, natural and unforced.
