Inventing tasks for slaves is not an easy game. The mistress must keep him busy and still make him horny. A lot of things could have the opposite effect. You realize, the job of a dominatrix / mistress is not as easy as thought.
If you force your slave to clean his shoes, it is best to wear them on your feet. He has an occupation and will be captivated by your wonderful feet. If you simply put him a pair of shoes that he has to clean, the air is quickly gone. The incentive is simply missing. Always try to find tasks for slaves that are directly related to you.
So close to the body and yet so far away
Erotic tasks for slaves with direct reference to you are almost mean. But that is the whole point. It should be difficult for the slave to fulfill his tasks to your satisfaction. Let him lick your shoes clean, but he must not touch you.
If he does touch you, you can punish him. Let him stand against the wall. He must not move a millimeter while you come closer and closer to him, let him feel your breath. If he does not obey, punish him. You can extend this game as you wish.
Tasks for slaves are not subject to any guideline, you have a free hand. Be creative, show him that he is very close to you and your body and yet somehow very distant.
Combine tasks for slaves with punishments
The purpose of tasks for slaves is to turn him on. Turning him on is all you want for now. The second idea behind it is punishment. You should give the slave tasks that he will find harder and harder to fulfill.
Make it almost impossible for him to satisfy you at the end. So you have the perfect reason to punish him. Sure, the tasks turn your slave on, but mostly it's the punishments that make him really horny.
Forbid him to touch you, he must not touch anything himself, he must let himself be tied up, endure whippings and co. Forbid him even the orgasm, if you can manage it.
Das sehe ich ein wenig anders. Natürlich ist e für den Sklaven schön wenn der Fuß der Herrin in dem zu säuberen Schuh steckt, aber Wunsch und Wirklichkeit sin das eine und das Schuhe putzen ob mit zunge oder Putzmaterial soll die Reinlichkeit der Herrin hervorzeigen nicht das Vergnügen des Sklaven. Für seine Herrin arbeiten zu dürfen darin liegt die Pflicht und auch Erfüllung, das sie den Schuh dabei anhat, das muss er sich erst verdienen
