A femdom training session turns into a brutal ballbusting extravaganza. The mistress, a stern and dominant woman, commands her slave to present himself for inspection. She runs her gloved hands over his body, pausing to squeeze and twist his testicles, making him wince. She then takes a seat, her heels digging into his back as she orders him to pleasure her with his mouth. As he dutifully does so, she increases the intensity of her ballbusting, leaving him a quivering, beg- ing mess, ready to serve her every command.
