Mrs Mari is still upset with her slave so she changes her shoes to some superb designer platform pumps. This pumps (mary jane style) have a little secret though. The soles are made of treaded rubber which means that once they start stroking the slaves cock he will be in excruciating pain. She first stomps mercilessly the slaves head and grinds her soles to her cheek. After being done with that she proceeds to stroke the cock harshly under the treaded rubber soles. The slave is in pain but he has to endure since Mrs Mari is expecting a cumshot. The slave is in pain and can cum so she orders him to masturbate. While he does, the mistress repeatedly kicks the slaves ball and stomps his cock. The does it for a few minutes and continues stroking his cock. She can see how red it is turning and swelling as the soles shred it apart. The slave has to take breaks in order to masturbate since he cant cum from the pain. In the end, he cant take it anymore and has to endure the last few burning strokes from those soles until he shoots a cumshot. Mrs mari steps on his cock and cum and is now pleased.
