Mistresses Lily and Gaia have been friends for a long time. They help each other out when the other has a problem. Mistress Lily asked for help from her friend to tame a stubborn slave who did not like following the mistress's rules. They called the slave over and commanded him to kneel. They were going to take turns humiliating him until all his ego vanished. They shit in his mouth and commanded him to swallow everything. They added piss to wash down all the poop.
