Mistress Sofie wanted her slave to do what she had asked him. She did not want to repeat herself and her slave seemed to always want her to repeat what she had said. She was pissed about that and she told him to pay attention. He had no choice but to do it as she used her dirty feet to punish him and warned him of worse if he did not change.
Lady Shay had dirty feet and she wanted them cleaned. She did not feel like going to the bathroom on her own and taking a shower. So she asked her slave to lick her bare feet which were sweaty as well as smelly. The slave knew he had no option but to do as he had been instructed. He was degraded but he licked them as well as she wanted.
