A 35-year-old Asian woman with long black hair, wearing a red bra and red panties, swimming underwater in an indoor pool. The woman has a cheerful expression on her face. Her skin and hair are completely soaked, with water sheen and clinging strands. The red fabric of the bra and panties is water-saturated, appearing in a deeper, darker shade of red, clinging tightly to her body with realistic wet folds and texture. Full body shot, including the face, captured from an underwater perspective. The scene is illuminated by light filtering through the pool water, creating caustic patterns and realistic underwater lighting effects, high-resolution, photorealistic, sharp focus on the subject.
