Lady Aische needed to dominate this guy and she had to do it by making him jerk off. That is what she felt he deserved and she did not hesitate to do that to him. She made sure that he learned his lesson and that he regretted what he had done. He did so and was teased and denied besides being made to do humiliating things in the name of jerking off.
Lady Aische was in a naughty mood so she teased anyone who was near her. This guy was the greatest beneficiary of what she did. He loved everything she did and he knew that he would finally get the chance to fuck her like he had wanted. But he was shocked when she rejected his advances and instead, she gave him jerk off instructions which he had to use to cum.
