A lamia with an impossibly elegant upper body, pale flawless skin flushed deep red and drenched in sweat, long dark hair tangled wildly stuck to bare shoulders and full heaving breasts, nipples erect and glistening wet, narrow waist arching as her powerful serpentine lower body writhes slowly, scales shimmering iridescent green and gold soaked with moisture in dim torchlight, coiled sensually on ancient stone floor with lower body shifting restlessly, tail tip curling and dripping wet, upper body leaning forward slightly, face turned directly toward viewer, heavy-lidded eyes with vertical pupils half-closed in ecstasy gazing at viewer, lips parted moaning loudly, tongue out, wet pussy visible at the junction where human body meets snake tail, glistening with moisture, scales wet with dripping water, body trembling, intimate dungeon atmosphere, pencil sketch style, delicate shading, mythical erotic tension, explicit sensual tension, masterpiece.
