Mistress Bertie caught her slave masturbating and she was not happy with him. She had to make sure that he learned his lesson and that he learned it the hard way. She forced him to lick her saliva and she used her smelly socks to choke him. He begged her to let him go but she ignored him. She made sure he learned his lesson and learned it the hard way.
When Mistress Katja looks through racks of clothing, she needs something comfortable to stand on. She calls her slave to her and she is happy to stand on his face. She doesn't care how long it takes, she has to find the right outfit to wear for the day. She shifts her weight from time to time but she won't stand on the floor. When he can't breathe and begs for mercy, she gets off his face.
When Mistress Katja has a hard time understanding why her slave didn't do what she told him to, she has to get answers. She is happy to put her knee on his throat, choking him. When he still makes no sense, she grabs her rope. She puts the rope around his neck and begins to pull tight, choking him. She demands to know why he can't do what she told him to.
Here we have a hot strangling session that nearly goes too far. Katja first of all binds his hands together with rope so the slave can't escape. Once he is bound tight, she strangles him first with her hands - which doesn't seem to be enough - and then with her bare feet and thighs. She tries from all angles and after a while she seems to be really causing some damage as his face turns a bright red.
