The boots just won't get clean! Princess Serena's slave has to make a real effort now so that she is satisfied with him. So far, all his shoe licking has barely left any clean spots on her boots. But Princess Serena wants that to change now and tries to motivate the slave to better performance... Hopelessly! The slave is unfit for the task. But Princess Serena already has another disgusting task for him and urges him to sniff her sweaty and strong smelling socks before he has to lick the sweat off her bare feet!
