Mistress Jenny had a new slave and from experience, she had learned that when her slave feared her, she had an easier time with him. So she set out to make this one fear her and she did this by forcing him to lick her feet and her Birkenstocks. As he did so, he feared her and knew she was not to be messed with and that is how they had a harmonious relationship.
Mistress Jenny felt that she needed to make this guy jerk off and she did not hesitate to do so. The mistress used her sexy feet to do it and she specifically made him watch as she played with them and flaunted them. Then she made it easier for him by giving him jerk off instructions. He was turned on and he came in record time before he got ashamed of what he had done after the fact.
