Mistress is preparing her slave for the rough treatment. First slave boy is wrapped in black cling foil and then securely tied to the bench. To make sure the slave does not make to much annoying noise when he suffers for his Mistress he is gagged. Mistress hooks him up to the electricity and starts to crank it up slowly but surely. The slave is totally helpless and in lots of pain, but Madame Caramel is still not satisfied. She puts clamps on his nipples. And those clamps are connected to a second TENS unit. Guess sometimes all Mistress needs from her slave is to suffer for her...
