Mistress Cat was pissed to find out that her slave was forgetful. She did not like it one bit and she had to make sure it changed. The mistress did this by forcing the loser to lick her bare feet. To make the punishment worth her while, the mistress made the loser lick dirty feet. It was a lot of fun for her to watch the guy humiliate himself at her expense.
Mistress Cat watched as this guy messed up. She had given him clear instructions on what to do and she was pissed that he did not follow them. She let him mess up and when he was done, she punished him. She used her stinky socks as well as her boots dirty sneakers to punish him. He had to lick them clean and he did. He was degraded and he learned never to ignore her advice and instructions.
Mistress Cat does not like losers taking her for granted. This one did and she did not take it kindly. She had to teach him a lesson and she did it using her bare feet. She had him lick the soles of her feet, which she had conveniently made sure were dirty. She had fun degrading and dominating him using her bare feet and made him regret what he had done.
