a fully nude woman sitting on a rock by a river. She has long, dark, wavy hair that falls over her shoulders. Her body is toned, with medium-sized breasts and a flat stomach. She is looking down and to the side with a slight smile. Her left hand is resting on her left thigh, while her right hand is holding a small, colorful cloth or piece of fabric. The background includes a clear, flowing river with rocks and greenery. The image should have a realistic style with high resolution and clear focus, emphasizing the explicit and sensual details of her nude body and the natural environment.
