Jessi’s Girls (1975)

The blonde in the pink dress is the first to grab attention, swinging her leg over the guy as he lies back against the grass. She grinds slow at first, rocking forward so her tits press against his chest, her cowboy hat barely hanging on. One of the brunettes — short hair, curvy — takes her turn from behind, pushing him into the other girl while the third woman watches before jumping in. They switch up positions fast: doggy against the wagon wheel, then face-to-face on a saddle near the horse. The lighting’s all natural, harsh in some shots but you still see the sweat on their backs and the way the girl with the white hat moans with her mouth wide. Camera stays wide for group shots, closes in tight when mouths are on skin.
