Booby Trap (1970)

A slim blonde with curly hair is lying on a bed under red lighting, hand on the sheets like she’s waiting for something. Cut to a guy kneeling in the desert, digging in the sand like he’s searching for treasure — turns out he finds more than he expected. Later, he’s on his knees holding something from the sand, maybe a clue or part of the booby trap setup. Back indoors, the blonde is on the bed getting fucked hard — they go from intense doggy style to her giving a blowjob with a blank look on her face. The whole thing has a gritty, cinematic vibe with wide outdoor shots and tight indoor close-ups on her mouth and tits. Three other guys are shown standing in a dim bar, talking like they’re in on the trap scheme — could be part of a larger plot.
