Heat of The Moment (1984)

Two thick dark-haired women with large breasts are going at it in the back of a moving car. You see one brunette with curly hair on top, riding her partner slow at first, grinding hard while the camera stays tight on their faces and tits bouncing. The second girl has a narrower face, lighter skin, and takes it with her legs up, pulling her partner down by the neck for deeper contact. Later they switch, and the more tanned one leans back against the door, spreading wide as she eats out her friend with long, visible tongue strokes. The lighting’s natural, looks like daytime on a rural road, and the shots stay medium-close so you don’t miss the wetness or the moaning. No penetration with a toy or dick — just pure girl-on-girl grinding, biting, and deep kissing with hands all over.
