Der Hexenritt (1991)

Blonde girl with wild curly hair, slim frame, and a visible tattoo on her upper back is bent over early on, ass out, lit dimly against a black curtain. She’s got a nose piercing and a black studded face mask on later, restrained with ropes and a metal hook in what looks like a dungeon setup. A guy shows up — brown hair, short, muscular — and they go at it after she’s strapped to a black box. The scene’s heavy on bondage, her wrists tied, camera staying wide to show the full setup, then closing in on her tits when she’s topless. They switch to doggy, he’s pounding her hard from behind while she’s still mostly bound, and you see the restraints stay on through the cumshot. Lighting stays low the whole time, giving it that raw, ritualistic vibe without going over the top.
