Demonic woman in a dark cave with a ring of fire

A voluptuous female demon with deep purple skin, wearing a barely-there outfit made of dark, tattered lace and leather straps. She is dancing seductively in a mystical cave, illuminated by eerie, flickering flames. Her long, sharp horns curl upwards, and her tail sways hypnotically with her movements. The ground is covered in dark, glowing symbols, and the walls of the cave shimmer with ancient, cryptic runes, adding to the dark and enchanting atmosphere.
