Psycho from Texas (1975)

Starts with this bearded white dude in his 30s sitting in a vintage car looking all broody like he’s about to snap. Then cuts to a dim shed where he’s holding a big knife to some skinny younger guy with slicked-back hair — you can see the fear in his eyes. The power dynamic is wild, no fake acting here. Later, the blonde chick from the jogging scene shows up, but the real action is the rough fucking between the two guys. Doggy style on a wooden table, the bearded dude slamming into him hard while the knife’s still in reach. Camera work’s solid, gets right in there for close-ups of the pounding and the facial expressions. If you’re into intense roleplay with a dark edge, this one delivers.
