Princess Serena was not happy with the manner in which this loser went about his work. She wanted him to be quick but at the same time for him to be systematic and effective. When he was not, she used her foot worship to torture him and to keep him on the straight and narrow. He was deathly afraid of her and he learned to do what she wanted and that she asked for.
Mistress Brooke was not happy with the progress that her slave had made. She wanted him to make even faster progress so she made him get used to being punished if he was slow. She started mildly by using her dirty and smelly socks to do it. She got him to lick her socks and she forced him to do all that she felt would be humiliate and he did.
