Mistress Sophie is sitting on a chair, with legs crossed in front of her slave, who is kneeling on the cold floor naked. They are looking at each other for a quite a few moments and Sophie suddenly stands up and sees if her slave got the message. Her problem is the laugh. He laughs if he is confused, if he did something wrong and so on. So she starts slapping his face, to teach him not to laugh while his mistress is around. Pinching his nipples and kicking him is also part of the lesson.
