When we need to take a shit there is nothing better than the ugly face of a loser, in fact to see his face gives us desire of shitting.
Sophia, Julia and Natalia have kidnapped the slave all weekend to shit him and piss him. They just want him to see their asses. They will make him feed with them , as a revenge for his bad behaviour. Also they make the most of giving vent to him physiologically and verbally.
One of the rules is that the slave should eat everyday with his meal under the toilet seat. Often he has bad luck and the girls need to use the toilet when he is having a lunch. Those times the slave must see how the girls fart and poo on his food unavoidably.
