When mistress Kira noticed that her slave was disobedient, she was not going to keep quiet. She had to make sure that she gave him the requisite punishment so that he learned to do things the way she wanted. And that is why she forced the guy to lie down and she gave him the trampling of a lifetime. He was not only humiliated, but he was also in pain.
Mistress Kira did not like how lazy her boyfriend was. She had tried to talk to him but he did not change. She had to make sure that he changed and that is why she trampled him on the couch and she made sure he choked on what she did. The mistress made him beg for her to let go and he even peed his pants before she let him go.
