Lady Ayse wanted to make sure that this guy was manipulated and that he did what she wanted. The mistress loves to manipulate guys and she had to do it to this guy. That is why she had to do what she had to do in order to get her way. So she turned him on with her hot body and she got him to do what she wanted but did not give him the cookie.
Lady Ayse's ex had been bothering her wanting to fuck. But she did not want that. When he persisted, she felt that it would be a great way for her to dominate him and have fun at his expense. So the mistress had the ex teased and as he waited to have fun with her, she denied him. But she gave him jerk off instructions and as he was about to cum, she ruined his orgasm.
