Les brulantes (1969)

Thick black guy goes at it with a slim brunette right on the sand, her ass bouncing in the air, face in the leaves while he pounds her from behind. The blonde is there the whole time, mostly just watching, crouched off to the side in a bikini, not doing much. You can see the cock stretching her out on several close-ups — fat, dark, sliding all the way in, both of them covered in sand by the end. The angle keeps coming back to her back arching, mouth open, hands pushing into the ground. Earlier scene shows three brunettes in a fake cave set, fighting like it’s part of some weird porn skit — hair pulling, screaming, totally out of place. But the outdoor anal is the real focus here, raw and messy with natural lighting showing every detail.
