Marissa brought her sexy friend for a barefoot walk in the woods. Obviously all four feet are really dirty after a while - that's when Marissa orders the slave to lie down at their feet and they both start trampling the slave. But they're not going to "just" trample him - they make him lick their dirty foot soles clean as well. These mean girls know no mercy and force him to clean every square inch of their dirty feet. He even has to suck the dirt off their toes!
