Robin's exploration takes a lustful turn as she stumbles upon an ancient, intricate carving of a woman pleasuring herself with a phallic stone artifact. Intrigued, Robin mimics the carving's pose, her fingers sliding into her tight, wet pussy as she imagines the ancient woman's pleasure. Her moans echo through the chamber, drawing the attention of a nearby sea creature, who becomes captivated by the sight of Robin's self-indulgence.
