These mistresses are friends and they stick together through it all. They made sure that this loser was punished for what he had done to one of them. When you mess with one of them, you have messed with all of them and that is why they had to punish him all of them. He was made to eat shit and to drink pee from many mistresses and he was thoroughly degraded.
Mistress Milana and her friends were tired of being perceived as weak and being treated badly by people. They wanted to stand up for themselves. So they created a group to promote their own cause. They gang up against guys who mess with one of them and that is how this loser found himself on their bad side. As his punishment, he was made to eat their shit and drink their pee.
