Sis gets punished for blackmailing brother with sex

Sis had a wild fantasy about her brother, and she used it to blackmail him into helping her out. But when her brother found out, he was furious. He decided to punish her for her naughty behavior, and he knew just how to do it. He took her to the garage and fucked her hard, making sure she knew who was in control. As he pounded her, he could feel her body responding to his touch. He had never seen her so excited. He was surprised by how much she enjoyed it, but he shouldn't have been. After all, she had been craving it for a long time. He had been too scared to give in, but now he wished he had. He had been denying himself for too long, and now he was making up for lost time. He had punished her, but he had also given her what she wanted. And he knew she would be grateful.
