Mistress Gaia knows how to have fun while humiliating a slave. She called her friend and made her ride the slave as if he was a horse. Then she whipped the slave so that he could go faster. It was both painful and humiliating for the slave, just the way mistress Gaia wanted it. She also stepped on his head using her high heels in a bid to let him know that if he did not do as told, there would be hell to pay.
