L’erotomane (1974)

Guy in his 50s, gray hair, balding, thick mustache, wearing a suit and tie, sitting at an office desk. He’s on a phone call, talking casually at first, but you see one hand slowly drop into his lap. Camera stays tight as he starts rubbing himself through his pants, then pulls his cock out — thick, average length, veiny. He jerks off steadily while still talking, no moaning, just focused, like he’s doing business on both ends. Lighting’s flat, looks like a security cam or basic camcorder, no edits. The whole thing feels low-key and real, not staged — like you’re watching someone who thinks he’s alone.
