Mistress Jenny had to punish her boyfriend because he had acquired some behaviors she did not like. And to make sure he did not do those things again, she turned him into a foot slave. She humiliated and dominated him cruelly using her shoes and her feet to make him realize that he had drop those habits. The guy had to drop the habits as he did not want to be humiliated again.
Mistress Jenny wanted to show this slave that incompetence did not pay and that he had to learn to do things the right way and he had to work on his core competencies and improve them. So she made him do it by trampling him and turning him into a foot slave. He had no choice but to do as she had instructed him and that is how he learned his lesson.
Mistress Jenny has a low sex drive and she sometimes has to force herself to fuck her husband. But today she did not feel like it and she knew he would want to have her later on in the night. She knew his signs so she waited until she started seeing them and she whipped out her stinky feet and she made them spoil the mood for him without him knowing she had done so deliberately.
