The femdom instructor takes a new submissive's testicles in her firm grasp, her eyes gleaming with sadistic intent. She lectures him on the art of pain, her voice as cold as ice, as she demonstrates with a series of cruel squeezes and twists. She forces him to his knees, his balls aching and swollen, and orders him to worship her feet while she continues her lesson, using a variety of toys to push his limits, from a vicious ball stretcher to a merciless electric wand. She pushes him to his breaking point, but she won't let him stop, not until he's learned everything she has to teach about pain and humiliation.
