Mistress Gabriella and her friends mistress Marianna and mistress Victoria had given this guy some work to do and he told them that he would do it but he did not do it as well as he had been asked to do. He basically did not follow orders. The mistresses turned him into a socks slave and humiliated him a great deal and even whipped his back for good measure.
Goddess Gabriella wanted to make sure that she humiliated this guy and she did so using her socks. Her socks were smelly and they were sweaty too but that is exactly how she wanted them to be before she used them to dominate the guy. He had no choice but to do things her way. Worst of all, the mistress did not even bother watching how he was humiliated. She was busy on her phone.
