The room hums with the low thrum of power as the Dominant, wielding a handheld Tesla coil, approaches their bound partner. The submissive's body is a canvas, their skin a playground for the electric currents that dance and bite. The Dominant traces the coil along the submissive's curves, leaving trails of goosebumps and gasps in their wake. The submissive writhes, their body responding to the unique blend of pleasure and pain, their cries filling the room as they beg for more, their limits tested in this intense, electric dance.
