Killing Obsession (1994)

Starts with this guy looking all serious in a suit, talking on the phone like he’s got a plan. Then he walks into a dim bedroom where a slim brunette with long dark hair is already half-naked on the bed. No slow buildup—just straight to him grabbing her hips and slamming into her from behind. She’s got a tight little body, and he fucks her hard enough that the bed creaks. The camera gets right in there for close-ups of her face when she’s taking it, and you can see every thrust. Lighting’s all moody and blue-tinted, which makes it feel like some kind of dark fantasy. Not a lot of plot, but the tension before the sex sells it.
