Create an ultra-realistic, high-definition 4K image of an elderly woman

Create an ultra-realistic, high-definition 4K image of an elderly woman, at least 75 years old, with a visibly overweight and sagging body. The woman is depicted from behind, lying under the sun. She is wearing an extremely small thong bikini made of a thin string that barely covers her buttocks, leaving the majority of her large, sagging buttocks completely exposed. The woman is topless, her bare breasts partially visible from the side, and she is comfortably relaxing in a sunbathing position. Capture the scene with photographic precision in 4K resolution, emphasizing the aged, sagging skin, deep wrinkles, and the minimal coverage provided by the thong bikini. The image should focus on the woman’s prominent, sagging buttocks, with particular attention to the extremely small thong bikini and the texture of her aged skin.
