Four Mistresses – Kira, Sofi, Dorimills and Agma train the slave by checking how well he has learned the smell of each Mistresss fart. This is not the first time that the slave has inhaled the farts of dominant girls, so he had to remember each Goddess by smell. The girls put a blindfold on the slaves eyes and made him kneel in the center of the room, while they themselves sat on the sofa. Then, in a random order, the Mistresses began to take turns approaching the slave and farting in his face, while the slave, deeply inhaling the fart of each girl, must guess who exactly farted in his nose at that moment. And at the end, the Mistresses removed the blindfold from the slaves eyes and ordered him to kiss their asses, and they themselves began to fart in his face without restrictions.
