The lesson for the slave polina is the best means for her to serve better. The slave worshiped the feet of Nicole and Cindy badly, so the girls decided to take the slave to the common entrance .. It's hard to imagine how many people pass through this entrance to their apartments. The girls soiled their feet and ordered polina to look at it. "Is that what you wanted slut? It feels like you don't like worshiping our clean feet.. you're doing it sluggishly! Do you really need to learn how to worship our feet well? We'll do it now and you'll try harder in the future!" - The girls were talking and wiping their dirty feet on the slave's tongue. As soon as polina licked all the dirt off their feet, Nicole and Cindy got their feet dirty again. The slave realized that next time she must not relax so as not to receive this humiliating lesson again.
