Mistress Marlena and her friend had taken their car to this mechanic and he had assured them that he would sort it out for them. They trusted him and they left it to him to sort out. But he did not do it the way they had expected it as the car still had issues when they went to pick it up. They were super pissed off and had to punish him which happened as they shit on him.
Mistress Luciana wanted her accountant to know that she did not condone the nonsense he was involved in. That is why she chose to make sure that he was cruelly and humiliatingly treated. The mistress did this with her shit and as he tasted her ass and got choked as she facesat him, he knew she meant business and so he took it seriously and changed as she wanted him to.
