Goddess Nika wanted to express her disappointment at what this loser had done and she knew it had to be something he would not forget in a hurry. So she used her bare feet which she had made sure were dirty to punish and to humiliate him. The mistress went ahead and she trampled him and she made him lick them before she let him go and warned him never to do it again.
Goddess Nika did not want her man to drive carelessly the way he had done. She wanted him to become a responsible driver so she used her boots to punish him. She asked him to pull over and when he did, she stepped on dirt and she went back to the car and she ordered him to lick the soles of her boots clean. He was shocked but he got the message she was sending.
Goddess Nika wanted this slave to lick her boots which were dirty until they were clean. He tried to refuse but she gave him a taste of what her boots were capable of and he was in pain. He decided that licking the boots was easier than being trampled by the mistress who had promised to ballbust him if he refused to lick her soles clean. He swallowed his pride and did it.
Goddess Nika did not like how her slave did not clean her boots properly. So she used them to punish him. She forced him to lick them and she trampled him with the same boots. She had no mercy for him as he knew how much she loved the boots but he did not clean them as well as he should have. It was time for him to learn from his mistake.
