Lady BlueIce found out that this employee had lied on his resume because he could not do half the things he had said he could on his resume. She felt cheated and she had to punish him since he was incompetent. The mistress crushed the shit out of him with her sneakers and gave him two weeks to know how to do it all or be fired. The guy had to work harder than he had ever done to gain the competence he required to keep his job.
Goddess Sheila turned her sneakers into a weapon and she used them to dominate as well as to torture this guy. She was out to degrade him as he did not do things the way she wanted. That is why the mistress forced him to lick the soles of her sneakers despite the fact that they were dirty. She laughed at him as he struggled to do what she had ordered.
Lady Kara was tired of her slave talking constantly. She wanted to have some quiet time and do her own things. When she realized he was not about to do it, she trampled him and sat on his stomach. She then had him lick the soles of her sneakers as well as her socks and bare feet. All this while she was chatting on her phone. That was meant to teach him a lesson.
