At first the slave thought that it will be his lucky day. He already knew that the girls want to punish him because he did a bad slave job last time. And then he realized that they want to trample him. But they took off her boots before. He was really happy - until they started the session! They did not took off the boots because they have mercy. The only reason was that they could trample his face better without shoes! And so the sisters punished him the way they like it - hard and brutal! They are the Sado Sisters!
