Today, Mistress Helen want to train her slaves in a different way. She was wearing white boots and light brown stockings. She put on white rubber gloves and began to play with the slave's cock by her hand. The slave groaned excitedly, but Helen felt very noisy. She took out her defensive weapon to warn the slave to be quiet, or she would cut off his cock. After that, Helen took off her stockings and continued to rub the slave's cock by her barefoot. At last the slave begged for her mercy and agreed to let him ejaculate.
