A photorealistic, cinematic shot of a stunning, athletic young woman with long dark hair, tanned skin, a perfectly toned body, and naturally beautiful breasts, wearing only a white bikini bottom and aviator sunglasses, seductively reclining on the white deck of a yacht. The yacht’s gleaming chrome railings, bright sunlight casting sharp shadows. Background, a crystal-clear turquoise ocean with sparkling reflections on the water and visible coral reefs, a small lush green island with palm trees, a curved white-sand beach, under a blue sky. Ultra-detailed skin texture, realistic reflections on the water, a luxurious yacht cruise, sharp focus, a masterpiece, top quality, natural lighting.
