A photorealistic medium shot of a young adult European woman with curly brunette hair, her skin and hair glistening with wetness, standing in an empty gym at night. She is wearing an oversized, soaking-wet light green long-sleeved buttoned-down shirt that clings to her frame, a soaked dark brown leather floor-length skirt that appears heavy with moisture, and light green stockings. A brown necktie is knotted at her collar. She is being restrained by metal chains held by her dom lesbian trainer lover, who stands partially visible in the shadows. The submissive woman displays an expression of intense arousal and submission. The environment is a dimly lit, high-ceilinged gym with polished wooden floors reflecting the low light. The wet clothing shows deep color saturation, heavy folds, and glossy specular highlights on the leather and fabric surfaces. High-contrast cinematic lighting, 8k resolution, sharp focus on the textures of the wet fabric and skin, detailed chain links, realistic anatomy.
