When Mistress Katja decides she is going to choke her slave, she does it in a calm fashion. She puts her slave on a ottoman and sits on his chest. She uses her hand to wrap around his neck and squeeze. When she gets tired of that, she sits her full weight on his chest and neck, forcing him to smell her pussy. She enjoys knowing that he is struggling to breathe and the air he manages to inhale is full of her pussy.
