El violador infernal (1988)

Starts in some kind of office or study with two dudes talking—one’s got glasses and a receding hairline, the other’s got a thick mustache and looks Middle Eastern or South Asian. Not much happening yet, just setting the scene. Then it cuts to a close-up of the glasses guy’s uncut dick, already half-hard, and he’s jerking it slow while staring at the camera like he’s about to lose it. Next shot’s him getting his cock deep-throated, face all twisted up, but you don’t see who’s doing it. Later, a redhead in a sleeveless top and a brunette with long hair are chilling in a living room, looking like they just finished or are about to start something. The real action goes down outside at night—some old pickup truck on a dirt road, and the guy with the mustache is fucking the redhead doggy style in the back while the brunette watches or waits her turn. Rough, no-frills stuff, but the outdoor setting and the way he slams into her make it stand out.
