After a walk barefoot in the underground parking, I decided to make my slave clean my dirty feet, using him as a doormat. He hates dirty feet but he must learn to clean them properly and swallow everything. The taste probably was not very good because he gagged a lot while licking them, and he almost throw up. I had to push my feet on his tongue and in his mouth because he was trying to escape but in the end you can see that he did a fairly good job.
