In the dimly lit dungeon, a subspace novice, eyes gleaming with anticipation, awaits her Master. He, clad in leather, holds an intimidating electro stimulator, its prongs glistening with conductive gel. Starting with gentle zaps on her inner thighs, he watches her squirm, her breath hitching as the current courses through her. He traces the device up her body, teasing her nipples, making her arch into the pain-pleasure. Her whimpers fill the room as he brings her to the edge, then backs off, building her anticipation for the main course.
