Sarah invited her beloved step-grandmother Raisa to visit. Step-grandmother Raisa is bored in her old age to stay at home and she gladly came to her step-granddaughter. "I have a present for you, dear step-grandmother!" Sarah said after a while. Raisa was very surprised when Sarah led iren out of the other room. "Who is this? What can she do? Is this a present for me?" Raisa asked. Sarah began to train iren and give her commands. After that, iren took off Raisa's socks and began massaging her tired feet. "Now this is your slave, step-grandma.. and you can do whatever you want with her! Look how she can suck feet!" - Sarah said and put her feet in the slave's mouth. iren sucked her Mistress's feet while Sarah and Raisa watched her. Sarah then ordered iren to suck and worship step-granny's feet. The slave worshiped the feet of the old woman while Sarah talked to her and humiliated her morally. Sarah wiped her dirty shoes on iren's tongue to show Raisa what her new slave could do. "This is a great gift, step-granddaughter.. thank you! Your step-grandmother is very happy!" Raisa said. Step-grandma was happy! Sarah gave iren to her step-grandmother. Raisa was very pleased and ordered the slave to mop the floor while Sarah was away. After some time, Sarah returned with her friend Rada and the step-grandmother complained to the girls about her new slave. "Dear step-granddaughter.. this slave does not clean the floor well. What should I do with her?" Raisa asked. Sarah immediately stuck a rag in iren's teeth and ordered her to clean the floor even better! Rada also shouted at the stupid slave and humiliated her morally. The girls put their feet on the slave's head and pressed her to the floor. After that, they ordered iren to beg Raisa's forgiveness. The pitiful slave bowed to Raisa and begged for forgiveness. "Lick my step-grandma's feet you whore and apologize better!" Sarah said. iren took out her tongue and started worshiping Raisa's feet. The girls watched the work of the slave and noticed the dirt on the floor. "That was the last straw of our patience!" Rada said. Rada, Raisa and Sarah got up and began to soil their bare soles. After that, iren put them an ottoman and carefully licked the dirt from their feet. Next time, she will listen to step-grandma Raisa better and follow her orders.
