Mistresses Rosella and Contessa had a student. They were teaching her how to become a scat queen so they showed her what to do and how to do it. They brought a slave and they had her do what she had learned. They were surprised with how good she was at shitting the slave and following instructions given that she was a new student and had not learned a lot.
This is the second part of a cruel scat party! The German scat queens from Berlin like to use their human toilet as much as possible! They gave him only short breaks and he has to prove that he is the best toilet out there! And because they don't want to spare him some ladies are already shitting into his mouth. But the old slave has to deal with something more than their shit...!
