Princess Kitty was out in the mud having fun and she did not know how much her shoes got dirty and when she tried wiping the mud off of them on the grass, she was told by the stable boy to stop it and that she should find another way to clean them up since the grass was aesthetic an she was ruining them and she did find a better way. His mouth and it did a very good job than the grass ever could
Princess Kitty did not like how manipulative her slave was trying to be and she had to make him understand that it was a toxic trait and he had to drop it and do it as soon as possible. So she used her boots to make him understand her better. She did this by forcing him to lick the soles and then she gave him a taste of the boots by trampling him.
