The slave has to kiss the soles of my boots. Inside them, my feet are getting warmer and warmer. If only he knew what was waiting for him in these boots… My feet sweat a lot in them and I prove it to him. I pull off one boot and let him inhale a sample of my dirty and smelly sock. Then I put my sweaty foot on the floor. A footprint of pure sweat forms, which he will lick up!
