Realistic, 8K, 45yo adult female bent forward over a plush velvet ottoman, back arched high, face twisted in a mix of pleasure and agony, eyes half-closed and glazed, lips parted and glistening with saliva. She wears the dusty-pink satin gown with the ruffled skirt hiked up to her waist, exposing her wide hips and thick thighs. A brutal, oversized luminous dildo emitting a neon-blue glow is buried deep in her stretched vaginal introitus, the internal light illuminating the walls of the vestibule and the surrounding labia majora. The cool blue light casts sharp specular highlights on the pink satin ruffles and her flushed, sweaty skin. Low side-angle shot, 35mm lens, dark room with the dildo as the primary light source.
