These boots are so muddy that the dirt sticks inches thick on them! They can't stay like this so Princess Serena has ordered her boot slave to com and clean the boots thoroughly with his tongue. If he has to, he carefully nibbles off the dried dirt with his teeth. His only job is to clean the princess's boots thoroughly. Princess Serena pays close attention to how the slave performs his task and makes it clear to him: lick, lick, swallow!
