A stunning nude woman with a smooth, toned, fit body, sitting on the edge of a marble bathtub in a luxurious bathroom with warm golden lighting. She leans back slightly, spreading her legs naturally, fully exposing her vagina. Her skin glows softly, with delicate highlights and realistic shading that emphasize her curves. Her expression is confident yet serene, with tousled wet hair clinging to her shoulders. The polished marble and candlelight reflections create a sensual, elegant mood.
