Brunette tied up and getting rough treatment

She’s lying flat on her back on some kind of metal surface, arms stretched out and pinned. Her short brown hair is messy, and she’s wearing a black top and a purple collar with a metal ring. Her eyes are closed, lips parted, like she’s either in pain or enjoying it. The lighting is harsh, almost industrial, with rivets visible on the metal walls around her. It feels like she’s being dominated — maybe restrained for a session. No one’s visible except her, but you can tell someone’s holding her down or working her. The vibe is raw, intense, and physical. She’s not moving much, just reacting to whatever’s happening. The whole scene feels gritty and real, not staged. No fancy props, just her, the metal, and the tension in the air.
