The best foot slaves need no discipline. They wait obediently for Mistress to return so they can do nothing but serve her desires. He waits patiently for her to return, right in the spot she instructs him to stay while she is away. When commanded, he removes her high heels and massages and licks her feet in the way she prefers. The best foot slaves are only concerned with pleasing the Mistress. Good boys get rewarded.
