Even the starting position in this video would push many slaves to the limit. Canvas wears a full body suit that covers him completely. A heavy leather mask additionally covers his face, so that the mistress no longer sees a human being in front of her, but an object that she can use at will. His arms are tied with ropes behind his back. In addition, a loop is attached to an overhead crane. There is no tension on the suspension rope yet. Suspicious are the strings dangling loosely from his balls. The red color makes it clear that they are worth paying attention to. So Canvas is now in a position where he has no way to escape or fight back. He is more concerned with not losing his balance and toppling over. Now the hellish game begins. Canvas is put in an extremely uncomfortable position. In a predicament bondage position. For this his arms are pulled up. This causes his upper body to tilt forward. A bent over position, as it is appropriate in the presence of the mistress. That's not all. To make it really a suffering, the balls are pulled tightly down. To relieve them Canvas goes into a squatting position. A massive strain on the thighs. Miss Yara is unimpressed and only pulls tighter. You'd think this was torment enough. But to the slave's horror, the mistress sees it quite differently. She gets a spiked ring, also called Kali's Teeth Ring and places it on the slave's cock. Due to the excitement, the big cock swells so much that the spikes just drill into it. Miss Yara visibly enjoys the situation. She stimulates the slave so that he is as hard as possible and suffers to the maximum. One could come to the conclusion that the slave would now have earned reward. But Miss Yara doesn't even give him a painless orgasm. No, the absolute opposite is the case. She takes a steel wool, which is intended for scrubbing pans and scrubs the maximally erect penis with it. Suffering and in pain, Canvas finally manages to have an orgasm.
