Step-sister caught fucking step-brother in the garage, gets punished

In the heat of passion, my step-sister was caught in the act with my step-brother in the garage. The sight of them entwined, their bodies moving in rhythm, was too much for my father to bear. He stormed into the room, his face twisted with anger, and dragged the little slut away from her lover. His punishment for her promiscuous behavior? A strict talking-to, a firm reminder of the boundaries of our family's taboo rules. But the damage had already been done. The sight of her bare ass, red from the spanking, only fueled my desire for her. I couldn't help but imagine how it would feel to be inside her, to taste her sweetness. I knew I had to have her, to make her mine. And so, I did. I fucked her hard and fast, my cock plunging deep into her tight hole, until we both were spent.
