The sex slave has been kept in chastity for two weeks - today he is released as the Mistress wants to continue his training in cum control - nothing worse that a sex slave with PE or no control! He must learn his cock is for his Mistress use - for her pleasure - NOT his own. Using her hand the Mistress brings him right to the point of orgasm and then stops (edging) a number of times. All the while devising cruel torments to further frustrate the poor slave including one where he must put his cock inside her but not move it.
