This guy had done some good work and mistress Dula needed to reward him. He did not want money and she knew that he wanted to get an orgasm. That is why she chose to give him a handjob as she could not fuck him. So she made him undress before she gave him a great handjob and he loved it so much. He could not help but cum after a few minutes.
Mistress Dula did not want to make this guy. He thought she did but she proved otherwise. She had teased him and done all things to make him think he would have a great time. But when she started to give him the handjob, she made it a painful one and the guy had to cry and beg her to stop. Instead of stopping, she told him to pay her to stop and he had to.
Mistress Dula knew that she had to dominate this guy and that is why she chose to do what she had done to the guy. She felt that the best way to handle the guy was to have him tied him while naked and she would have a freehand to work on his dick as she wanted. That is exactly what happened and she used it to have fun at his expense.
Mistress Dula and her classmate had a bet. If she won it, she would make her classmate do whatever she wanted. If he won, he would make her do whatever he wanted. So he won it and he told her to give her a handjob while she was almost naked. She had no choice but to do what her classmate had asked her to do. It was a great handjob.
This guy was so horny that he had to cum. He did not want to jerk off so he begged mistress Dula to put him out of his misery. Since she could not fuck him, she agreed to help him but he would owe her. And it was not to be through sex. The naughty mistress did it with her handjob prowess and made him have an orgasm to remember.
