Pamela considers zoe one of the most pathetic and useless slaves.. Today she decided to test her for the first time. Pamela ordered zoe to worship her feet and watched her efforts. zoe tried very hard to please her Mistress but Pamela was getting more and more boring every second. Pamela wanted to have fun and humiliate zoe more and she came up with a great idea. "Listen to me carefully whore .. Now you go outside, go to the first passerby and ask her to spit in your disgusting face! You will film it and send it to me! After which you will bring her here and you will lick her feet. You got it, you idiot? Pamela asked. "Yes, Mistress .." - zoe answered and began to gather outside. Pamela pushed her out the door and sat on the couch to wait for fun events. zoe went outside and approached the first girl who passed by. "Hello.. I know it's strange, but could you spit in my face and videotape it! If you don't then my Mistress will punish me. Please." - zoe asked a passing girl. The name of the passing girl was Sofia, and of course she was confused. "Do you have a Mistress? Hmm.. that's weird. No problem - I'll spit in your face!" - Sofia said and spat in zoe's face. zoe thanked Sofia and sent the video to Pamela. Pamela watched the video, laughed, and reminded zoe of the second part of the order. "Could you come up with me to my Mistress' apartment so I can lick your feet?" zoe asked. "What?? Lick my feet? It's really very strange.. But they are very sweaty, I haven't changed my socks for a long time. Alright, let's go." Sofia agreed. When they entered the apartment, Pamela greeted the new guest, ordered zoe to undress, kneel, put a collar on her and lick the guest's sneakers. The sneakers were dirty and zoe felt that they had not been washed for a long time. Sofia didn't fully understand what was happening.. "Don't worry, this whore is a complete nonentity, she deserves only such treatment.. Let's go into the room and she will lick our feet." Pamela said to Sofia. The girls went into the room and sat on the sofa. "Will she really worship our feet? I didn't know my feet would be licked today hahaha! They are very sweaty, I didn't wash them." - This confused Sofia a little. But Pamela assured her that everything was in order and that zoe was a loser who should lick the sweat off their feet. At first, zoe sniffed loudly at Sofia's stinky and worn socks. A strong smell of sweat emanated from them .. Pamela ordered the slave to suck out all the sweat from her socks, after which she pushed them into her mouth. zoe began to worship Pamela and Sofia's bare feet, licking them from heels to toes. "To be honest, this is the first time I've seen this. It's weird and funny at the same time!" Sofia never ceased to amaze. Today Pamela had fun as it should. Sofia discovered new sensations. zoe received a portion of humiliation and shame. Everything is in its place.
