Stepmom gives stepson a lesson in self-control

This story is about a young man who finds himself in a rather uncomfortable situation with his stepmother. She has a habit of walking around the house in her underwear, which he finds very distracting. One day, she decides to give him a lesson in self-control. She tells him that he needs to learn how to resist temptation and not to touch what doesn't belong to him. She then proceeds to take off her top, revealing her beautiful breasts. She tells him that if he can resist the urge to touch them, he will be rewarded. However, if he fails, he will be punished. The young man is torn between his desire and his fear of punishment. He struggles to maintain control, but eventually gives in to his lust. He takes her breasts in his hands and begins to pleasure her, savoring every moment. In the end, he is rewarded with a blowjob from his stepmother, who tells him that he has passed his test.
