Mistress Jessica: Lick my Doc Martens boots clean.I was on the train for 6 hours today and the soles of my Doc Martens boots are sticking a little. The soles are also dusty from the station and the train. You, as my slave, will now lick my boots clean. I have large feet and correspondingly large shoe soles. That means you have a lot to lick. Start with your task. I will give you my instructions.
