Part 4 … The mistress has been at a party for hours and has chained her slave in the cell where he has to wait for her. The slave is now securely fastened to chastity belts, so the mistress does not have to worry that he jerks again without permission. Damned to inactivity, until the mistress returns, the slave must seriously consider how to improve his performance and obedience. Otherwise he has to live with the fact that his punishment is carried out without mercy. To his regret, the mistress quickly learns how to treat the permanent wanker in order to make progress in his behavior … The multi-part story shows how an obedient little wanker becomes a very brave and absolutely submissive slave. As the mistress says so nicely … “If you have a man by the tail … then you have it all”
