Realistic, 8K, 28yo adult female with a sharp human face and amber golden eyes, long sleek white hair pulled into a high ponytail with a white fabric wrap. She is straddling and riding a green dildo, her hips tilted forward as she slams the shaft deep into her pussy. The thick pink shaft is buried to the base, stretching the vaginal introitus and the lateral labial folds, with glistening lubrication coating the interface. She wears a high-collar black and white bodice with gold filigree embroidery and ornate black pauldrons with gold trim on her shoulders. Her expression is one of intense focus and pleasure, lips slightly parted. Dark studio background with deep blue-grey gradients, three-point studio lighting creating sharp highlights on her skin and armor, 85mm f/1.8 lens, shallow depth of field.
