Avril enters the apartment and sees how iren dutifully cleans up .. Avril really liked it and she decided to make fun of her ex-mistress. "Why don't you meet me, whore? I don't get it.. kneel in front of me!" Avril said. iren at first did not understand such impudence .. but remembered the previous humiliations and decided that it was useless to argue .. she knelt down. Avril approached her and gave her some slaps. She ordered iren to bow to her, apologize and worship her dirty sneakers. iren felt like the lowest creature on this earth .. she bowed to her former slave and licked her dirty sneakers. This amused Avril even more. "Ugh.. your nasty tongue turned black from my sneakers! LOL! I love it! Now smell my socks. I haven't changed them especially for you, ex-mistress!" - Avril continued to taunt and shoved her sweaty socks in iren's face. She used the phrase "ex-mistress" to make iren even more ashamed and humiliating. After that, Avril's smelly socks ended up in iren's mouth. "Delicious socks? Now it's time for my bare feet.. No, no, no.. not so fast! You think you deserve my clean feet even if they're sweaty! I don't think so! LOL!" - Avril had fun. She liked to humiliate iren. Avril thoroughly soiled her feet and returned to iren. "Now you can start, my ex-mistress!" - Avril grinned .. Her feet were black and soon iren's tongue too .. iren felt a strong shame licking dirty feet of her former slave .. just a couple of days ago everything was reversed, but now nothing can be returned back!
