This slave had not been punished in a long time and he thought that it was going to be as usual even today. But today the mistress had reached her limit and she had to punish him. She felt like it was imperative that she taught him a lesson so that he lessened his unruly behavior. So she used a cane to instill discipline on the slave and it worked.
Lady Tanja likes it when people are attentive. She wanted this loser to be attentive but he was not. She was not happy with him and she had to show how unhappy with his lack of attention and focus she was. She took a cane and she whipped him painfully. The mistress caned the loser cruelly and to make it worse, she made sure he was naked before she caned him.
