Mistress Kristina Rose likes to mistreat the balls of her slaves and she enjoys listening to their cries of pain while it is being done by her. With her slaves mind secured in a wooden box and his balls and cock helplessly trapped at a cock plank, Kristina gets her servant right where she needs him.Kristina proceeds to provide a barrage of insult into his balls and cock, such as slapping them, hitting them with a wooden mallet, using a bulbous vibrator on them, and massaging a Wartenberg wheel on them, all while laughing and grinning at his suffering. She then employs a kiss, attaching clamps then ordering him to create them jingle to do that, he has to damage his own balls. Kristina laughs in his agony as she sexily dances above him, enjoying her game.
