Cruel Mistresses: Slippery Gloves

Mistress A. is slowly and delicately milking her slave, whose balls are stuck between two metal rods. The pain makes the milking strangely odd, because the pain and the pleasure is mixing with each other and with the feeling of being forced into this situation. He can’t do anything, because he can’t move and Mistress’s slippery gloves slowly makes him reach his orgasm.
