The slave is fully aware that he is now completely helpless against Mistress Anfisa. She can do anything with him, no matter what she feels like. He belongs to her now! Mistress Anfisa has only one thing in mind though and that is to control his breath. For this she puts both hands over his mouth and nose and gives them a firm squeeze. She has his oxygen supply well under control and only occasionally gives the slave the opportunity to compensate for his oxygen deficit by allowing him to breathe for a short time. Then it starts again from the beginning because Mistress Anfisa wants to find out where his the limit of his oxygen deprivation lies!
