Today I've taken my slave into a camper van and parked it right in the middle of a large busy parking lot - with the van's big windows there's no doubt that a lot of people will see what's happening inside. He has to kneel down in front of the bed I'm lying on and then I make him lick the dirty soles of my tight-high boots, make him kiss 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 doesn't want to be publicly shown as a slave - but that's just what's happening! :-)
