Mistress Claudia had a slave who loved to be naked around the house. It made her uncomfortable and she told him. But he did not want to change and she had to find a way to change him. So she used her pink heels to trample him and to make him change as the pain was too much and he did not want to undergo such pain again from her.
Mistress Claudia did not want to have a slave who had poor memory. She wanted to jog his memory and she did it using her feet. She humiliated him and had him lick her feet and endure her trampling him. The pain and humiliation of it helped him to learn to remember things in order to avoid such treatment in future. It worked and they had no other problems after that.
