A good slave is expected to do everything for his Mistress. And of course, that includes cleaning. Anna Petronova and I, Lady Blackdiamoond, sit together, chatting, looking at our smartphones, and ignoring the cleaning slave as much as possible. After all, to us, he's nothing more than an object. But that doesn't mean we don't have to check whether he's done a thorough job. And since we've already established that he's nothing more than an object to us, we naturally have to test how comfortable he is – by making him serve as a chair for both of us at the same time.
