When a sub serves, one of the first things I get them to do is get down onto their knees and kiss from the heel of my foot, all the way up my leg, over my ass cheeks and back down my other thigh, calf, right back down to the heel of my other foot… I tell them how I treat them for the rest of our time together depends on how well they do this first task. What do you think I’m assessing while it’s happening? Do you think you’d do a good job?
