Mistress Catherine de Sade's new slave has been so good, she thinks he might deserve a reward.  Catherine is proud of the marks she's left on her slave's dick, but decides he needs to be tortured a little more before he gets any reward.  She starts to attach clothes pins to his body and smacks them off with a cane.  As she ties together some of the pins on his stomach, she bites on his balls and canes his cock.  All at once, she rips the clothes pins off her slave.
