The slave is tied down to the bondage board. Mistress Isadora steps on his cock and balls with her shiney black boots. She crushes his nuts under the sole of her boot. She then ties the slaves’ cock and balls making them very sensitive. Pulling on the rope, she yanks on his balls and digs her heels in his balls as he cries. Mistress Isadora uses the pointy tip of her boot to dig into his cock.
