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.
Mistress Jamie Kate had tried all she could and now she was doing anything that came to her mind. She made her slave go on all fours like a pony. Then she rode him and and had fun humiliating him and ordering him around. The slave was humiliated while the mistress had fun. The slave's back was aching from the strain of carrying her but she did not care about how he felt.
