Rada and Sarah believe that iren deserves only such treatment. They strongly give her slaps and humiliate her morally. The pathetic slave is crying, but the girls start slapping her harder and harder every minute. They use the slave as a trampoline and jump on her back. The slave's face turns red and Rada and Sarah only laugh at iren's humiliation. Slave is ready to do anything for her Mistress.. she cries and compliments them while they keep slapping her.
