California Skin (1996)

Blonde girl in a slim bikini starts off sitting near an oil rig, sun beating down, long hair flowing, looks like she’s modeling at first. Next scene she’s outdoors on the beach, brown-haired girl now, on all fours in a bikini, ass pointed out, facing the water. Then it switches back to the blonde, completely nude this time, lying on her back in the desert sand, legs spread, getting fucked. Camera stays wide, natural light the whole time, no cuts to cheesy close-ups. You see the full body movement, sweat, sand sticking to skin — feels real, not staged like some studio shit. The sex is straightforward but the setting makes it stand out. No fancy edits, just two women, different hair colors, slim builds, taking turns getting pounded outside.
