Heel Care with the Slave's Mouth: A Lesson in Diligence

After a short walk in my new red shoes, my slut had the honor of cleaning them. Of course, with his balls tied up, so I could scold him if he didn’t do it properly. The sight of him crouching on his knees in front of me, carefully removing every speck of dirt from my shoes, is both amusing and arousing. His hands tremble slightly as he tries not to make any mistakes, and the tied-up balls serve as a constant reminder of who’s in charge. Every mistake he makes is punished with a gentle tug on his balls, causing him to moan in pain and shame. It is a moment of complete control, in which I determine the quality of his work and push him to his limits. He knows that he is completely at my mercy and that I am monitoring his every move.
