Mistress Gaia wrapped a black plastic bag around her slave's neck with only holes for his mouth and nose - he isn't allowed to see her naked behind as she squats over his face. What he didn't know before - she has a terrible stomach flu at the moment and will dump a huge load of stinky diarrhea on his face. The poo more or less splatters out of her butthole and covers the slave's face within seconds - of course he gets quite a lot into his mouth as well - and he already knows that he'll have to eat it completely to satisfy his scat mistress.
