The All-American Woman (1976)

Redhead in her 30s with short hair and a slim frame dominates the opening scenes, first lying in bed in a dim bedroom, then waking up with a male partner in his 20s. They start slow—kissing by a window, close-up shots showing deep tongue action, hands roaming over bare skin. She takes control early, riding him in soft focus, then switches to doggy style with hard, jerky movements that shake the bed. Camera stays tight, rarely pulling back—most of the action is close-ups on her ass, his hips slamming forward, her face in the mirror later as she watches herself get fucked. She spends a solid minute sucking his dick after, loud slurping sounds, head bobbing fast, throat bulging. No wasted time between acts—everything flows like real sex, no pauses, no awkward cuts.
