The Mistress attaches weights to the slave's cock and balls. She stick needles in his body and whips him with a mean little whip on his ass. His ass is red and every hit he takes from the mean whipping Mistress he feels more and more pain. Still, he stands there, motoinless. Not allowed to make a sound. The weights give him pain, the needles stick in his moving body. The Mistress loves every second of this powerplay, the slave has to endure it.
