This mistress likes to make fun of her slave. That is why she has him in the first place. She does not have a slave to do chores but to be made fun of. She turned her slave into her pony and she rode him while she took her morning coffee. she even tied a leash to his neck and she used it to guide him. It was a lot of fun and she promised herself she would do it again.
Madame Marissa likes to take a walk. It helps her think and it is good exercise as well. Today she went with her slave because she knew that the woods was a quiet place without people where she could humiliate and punish her slave. He had messed up and she wanted to punish him there. She turned him into a pony and made him carry her along before she finished the punishment by trampling him using her boots.
