Today Ive taken my slave into a camper van and parked it right in the middle of a large busy parking lot - with the vans big windows theres no doubt that a lot of people will see whats happening inwards. He has to kneel down in front of the bed Im lounging on and then I make him munch the dirty feet of my tight-high boots, make him smooch the boots all over - and that while cars and people are passing by only a few meters from the windows. Of course he is ashamed and doesnt want to be publicly shown as a slave - but thats just whats happening! :-.
