Our foot slave has a lot to do now, because Princess Serena and I have really nice stinky feet and he has to lick them clean. While he licks Princess Serena's feet, absorbs the dirt, smells her foot scent and enjoys the strong taste, my feet are still sweating. They are still in my transparent boots, where no air can get in. If our slave gets thirsty, he could drink the condensation from my sweaty feet. But he will lick the sweat frommy feet first!
