A particularly intense ballbusting session awaits my helplessly bound slave. I fixated him to the bed with the Segufix system, a special fixation method used in nursing care to take away a patient´s freedom. To make his testicles even more sensitive for the painful kicks, I first take care of my slave´s dick. I stroke him thoroughly, until he reaches orgasm. As soon as cums, the real punishment begins. Due to the climax, his sensitivity is at its absolute peak. Now I administer merciless kicks to his balls with my massive platform boots. Then I take off the boots and continue kicking his reddened scrotum barefoot with full power. I stand on his testicles with my full weight and crush and hit them with my hands, until they are swollen.
