Punished for Jerking

Mistress Nightshade caught her slave jerking off without permission. For his punishment, she ties him down to a table and begins busting his balls. After she warms him up, she attaches a bunch of metal clips to his balls. Now that his balls are extra sensitive, she continues to paddle and smack them. When she tires of this, she stands up and kicks his balls until she thinks he has had enough.
