This mistress did not like how her professor was unjust to some students. She wanted fairness from him and when she did not see it from him, she had to punish him. She did it cruelly and forced him to make amends. She used her riding boots to torture him and he had no choice but to accept what she did to him and promise to change for the better.
When lady Alice noticed that her slave was becoming disobedient, she had to do something about it. She chose to punish and humiliate as cruelly as she was able to. So she used her boots to trample and to stomp on him. The pain he felt communicated to him that she was not going to allow him to mess with her. He never pissed her off again for fear of what he would do to him.
When this guy messed with mistress Gaia, he did not imagine that the punishment would be as cruel as it was. The mistress did not waste time punishing him. She got him to strip naked and she used her boots to trample his cock. It was painful but she did not care. His pain was her pleasure and she was sure he had learned his lesson and would not repeat his mistake.
Lady B was bored and had nothing better to do. Being a mistress with a fetish for crushing, there was nothing else she was going to do besides crushing things for fun. She had a few balloons left so she inflated them and she had fun crushing them. The mistress enjoyed the sound of them popping and she managed to pass some time before she went to look for something else to do.
Lady Krasaviza likes to experiment with different punishment methods. Today she chose to cage her slave when he messed up. She even made him wear a diaper so that he would disturb her with calls to go to the toilet. After she felt he had stayed in the cage long enough, she got him out of it and she turned him into a boot slave. He licked her boots and got spat on before she felt it was enough.
