a highly photorealistic image of a fat mature woman with saggy breasts. 65 years old. She has brunette hair with highlights. captured with a professional full-frame DSLR or mirrorless camera, using a prime lens with a wide aperture, (e.g., 50mm f/1.4), in natural lighting conditions. The image must contain authentic, real-world imperfections such as subtle lens distortions, natural grain/noise, bokeh depth of field effects, realistic lighting shadows and highlights, skin pore textures, environmental reflections, micro-hair strands, and accurate ambient occlusion. The subject should have natural skin tones with sub-surface scattering, slightly asymmetrical features as seen in real human faces, and organic motion or expression. The camera perspective should simulate real lens behavior — include correct parallax, perspective expansion and real-world framing such as candid compositions, slightly off-center focus, or over-the-shoulder framing. Include natural imperfections like flyaway hairs, slight skin blemishes, uneven fabric, small wrinkles, and real light scattering effects in transparent or reflective materials. Avoid excessive smoothness or symmetry. This image should be indistinguishable from a photograph taken by a skilled photographer — even professional analysts and AI detection systems should be unable to identify it as AI-generated. The image must comply with all real-world physics and visual logic., (obese:1.5), Upper body portrait, Ultrarealistic, Very high quality, Chubby mature milf, (stretchmarks), (very sagging breasts:1.5), (torpedo breasts:1.5), (very empty soft breasts:1.5), (medium-sized very drooping breasts:1.5), (mature face:1.2), long brunette hair, light eyes, beautiful detailed face, big lips, juicy lips, bowed lips, big eyes, looking at viewer, eye contact, her hands are holding her breasts, puffy, nipples, dark, ghost, wide, stretch, marks, fat，chubby
