(masterpiece, best quality, ultra-detailed, photorealistic, 8k, RAW photo), full-body back-view portrait of a breathtakingly voluptuous busty 20yo woman with an extreme hourglass figure, posing in front of an English manor. She has flawless olive skin, long, cascading dark waves black hair in thick, sensual waves, and a smoldering, seductive smile directed at the camera. She is wearing an incredibly tight, form-fitting, strappy pink satin mermaid gown with a big heart-shaped butt cutout with a white fur lining, revealing her gluteal cleft and her magnificent full booty. She wears no panties. The gown is backless and has a very strappy and revealing corseted bodice that violently cinches her impossibly small waist. Very muscular arms. The pink satin fabric clings like a second skin over her wide hips and thick thighs, outlining every single curve of her lower body in explicit detail. From the knees down, the dress explodes into a voluminous, multi-layered pink skirt of organza and tulle that pools elegantly on the ground. She is standing outdoors on a gravel path next to an expansive, vibrant green lawn. In the background is a large, stately chateau with a green roof, surrounded by trees with brilliant yellow and orange autumn foliage. The lighting is soft and natural, characteristic of a bright, clear autumn day. The focus is sharp on her, with a gentle bokeh effect on the chateau in the background. One of her toned arms is raised behind her head, pushing her tits out even further, while her other hand delicately toys with the dress strap on her shoulder. She is wearing an elaborate pearl necklace. Cinematic lighting, sharp focus, high contrast.
