Canvas stands completely at the mercy of his mistress. His hands and arms are in a leather arm binder and tied tightly behind his back. The leather mask covers his face. He avoids movement so as not to lose his balance. But this is not enough torment for his mistress, Miss Yara. No. She begins to turn the crank with pleasure and slowly but inexorably the slave's hands lift. This compels him into a bent-over position. His cock is stuck in a steel penis cage, which proves to be very restrictive right from the start. The cock presses against the grid from the inside. Now the mistress also attaches the balls to the spreader bar. With this the slave is made to bend his knees and is now faced with the agony of choice. Does he want aching balls or aching thighs. Yara enjoys stimulating him for a while and makes him hope for an orgasm. Several times it is very close. The frustration then becomes maximal when Yara locks the slave back into the penis cage. Unsatisfied and maximally aroused.
