Lady Shay was out to determine what this guy's pain threshold was. So she used her whip to do it. He was shocked at what she chose to do to him and he wondered why she had done it. But she did not care to explain and she did it with the help of her friend. They whipped him all over his body including his dick. His body was red and in pain.
Lady Shay was afraid that her husband would objectify her if he continued to watch porn. And that is why she had to ensure that he stopped doing it. She had tried to ask him to stop but he did not. So she used her whip fetish to do it. He was made to undress and while naked, was whipped all over his body and that is how he stopped watching porn.
Lady Shay wanted complete information as she could not work with little or useless information. She was involved in a high stakes mission and she had to get the right info. So she whipped this guy to make sure he stopped being cagey with the info she wanted from him. As the pain got to him, he regretted his stance and he gave her the info that she sought from him.
