Photorealistic 8k, ultra-detailed. An extremely frail, anorexic, miniature redhead girl with a very thin, boyish physique. Completely flat chest, no breast tissue, protruding ribs, narrow hips. She is sitting directly on top of a wooden table, straddling it, with her buttocks pressed against the surface. Her legs are spread wide apart on the tabletop, facing the camera. Wearing microscopic, tiny string panties that are far too small, barely covering her vulva, the fabric is strained and almost invisible. Detailed pubic hair growing around her vulva. The labia majora and minora are visibly swollen, engorged, and aroused from sexual excitement. Wetness glistening on the swollen folds. Pale freckled skin, messy red hair, intense expression, focused heavily on the enlarged, throbbing crotch area, high contrast, cinematic lighting.
