Matinee Wives (1970)

The blonde is on her knees first, sucking the brunette with her hand on the back of the head, both naked on the bed. You see the brunette’s slim body arch when she gets fucked in doggy, the guy pounding her from behind with the pillows getting shoved aside. They switch to missionary after, the blonde on top grinding slow before picking up pace. Later the same brunette gives head in close-up, lips stretched around a thick cock while the guy grips her hair. The lighting stays low throughout, mostly indoor shots with tight angles on faces and thrusting hips. No bar or office action makes it into the final cut — just the bedroom scenes with the two women taking turns on their partner.
