Beatrice, Dori, Jenny and Marina are friends and study at the same university. They often spend time together. They go to parties, do their homework, ride a car, walk, etc. But Marina is a weak link in their company .. the girls constantly tease her, joke about her .. And today they came up with entertainment. They decided to finally show her her place. The girls rode the car and ate sweets after university.. "Maybe we can go home and play different games?" Beatrice suggested. The rest of the girls looked at Marina mysteriously .. because they knew what awaited her. "Would you like to carry our bags? We are very tired. Will you do it for us?" - The girls asked with a smirk when they entered the entrance. "Of course. It's not difficult for me. You are my friends!" - Marina said and took the girls' bags. Beatrice, Dori, and Jenny looked at each other and giggled. Marina did not understand that she was being used. When the girls entered the apartment, they asked Marina to take off their shoes. "My feet are tired. Take off my sneakers, please." - Jenny said. "Mine too." Dori said. Without another word, Marina bent down and removed the sneakers from Jenny, Dori, and Beatrice. Why not help my best friends? Marina thought. After that, all the girls sat on the sofa. "Could you sit on the floor? For four, this sofa is too small." Beatrice said. "Yes, and bring us an ashtray. We want to smoke." Dori added. Marina does not refuse her friends.. she brought them an ashtray, sat on the floor in front of them and held it while they smoked. Marina did not understand the jokes and ridicule of the girls, she really considered herself equal to them and their friend. "Give us a foot massage, please." Dori said. Marina, as a good friend, began to give them a foot massage while the girls continued to smirk haughtily. "Look what I have for you! Do you like it? I think this will suit you!" - Beatrice brought the collar. Marina doubted but put it on .. she did not want to upset her friend. "Let's all play a game together! Close your eyes. Now you will sniff our socks and guess whose they are" - Jenny said and the girls laughed. "Hmm.. it's a strange game, but if you want, we'll certainly play." Marina said. Marina sniffed the socks of her friends and did not fully understand that they were laughing at her and not at what an interesting game it was. "And now a new game! You will be our pet. We will walk and you will crawl after us! Isn't that fun?" Dori laughed. "It's really strange. Is it really a fun game? Well, I believe you.. you are my friends. Let's play" - Marina answered. Beatrice, Dori and Jenny took Marina on a leash like a pet, took pictures and laughed .. only Marina did not understand that the girls humiliated her and tried to have fun with them. "And now another game! You will lie like a worm at our feet!" - Jenny said. The girls handcuffed Marina and continued to taunt her. "This game is called whose feet taste better. Lick mine and tell me what you think!" Beatrice said and brought her foot up to Marina's face. "Do I need to lick your feet? Oh.. every time the game gets weirder and weirder.." Marina said and pulled out her tongue. She lay in handcuffs and could not even move.. she licked her friends feet while they laughed at her helplessness and insignificance. "What a good girl you are.. You are our best friend! Now clean the sweat off our feet! You know how long we were at the university and then went out together. Get your tongue out." - Said Jenny and the girls sat down and stretched their feet in front of Marina's face. Marina licked bare and salty feet of the girls. When their feet were clean, they put a gag on the pitiful Marina so that they could no longer hear her. From now on, Marina will only speak on command and follow all the orders of her friends. And Marina already understood that these were her former friends .. now they are Mistresses for her. (English subtitles)
