Princess Serena hates disappointment and that is what this loser did to her. She asked him to lick her boots as punishment and he did it. She made sure he had licked the boots as well as if she had cleaned them with water and a rug. She then pulled his hair before chasing him away from her sight. She threatened to trample his balls if he did get out of her sight.
Princess Serena was not going to let this loser get away with being a bully. She hated bullies and she wanted to rid her neighborhood of bullies. So she trapped this one and she used her high heels to trample him and humiliate him. He could do nothing about it since she did not fear him. She taped his mouth so that he would not scream then she slapped him and trampled him using heels.
Princess Serena uses her boots to punish a slave is he does not listen to her or follow her instructions. She has different ways of punishing a slave and it is all dependent on the kind of mistake he or she has done. For this loser, she chose her high heels. She used them to crush him and to trample and torture him as cruelly as she felt like doing it.
