Prompt:

A muscular man is dressed in a translucent white linen sheet, playing as a muscle ghost full of primitive strength. The sheet outlines his thick chest muscles and well-defined abdominal muscles in the dim light and shadow. In the dark room full of dramatic tension, he is masturbating, the erect penis is completely exposed, and the picture is fixed at the moment of intense ejaculation, and the thick white semen is sprayed and splashed, capturing very dynamic fluid details. Film-level realistic texture, extremely high image quality, the sweat shimmer on the skin and the wrinkle texture of the sheets are clearly visible, and the cold side light creates a sly and attractive visual atmosphere.
