The rumble of a car engine echoed down the tree-shaded street as 17 year old Joseph Cohen's 1990 Ford Explorer made its way toward his house. Somehow the think still managed to drive despite being older than he was. His friends had decided to name it "The Tank" since it had thus far proved nigh indestructible. Even after his sister ran into some little sports car, it still managed to chug along undeterred.<br/><br/>He smiled as he thought of his sister, who was waiting for him at home. He had come home late because the teacher had needed someone to help him clean up the chemistry lab after class, and Joseph had opted to help out. Even so, he was eager to get home where his younger sister was waiting for him. She was a little younger than him, and drop dead gorgeous as well. This was especially good for him, as they had been sleeping together for nearly a year now.<br/><br/>He wasn't really sure how it got started, but they had just sorta moved from being merely siblings to passionate lovers. They did it several times a week, and the best part was, they didn't even have to hide it from their mom. Oh they had tried at first, but she caught on quick, but instead of splitting them up or something, she started giving them tips, and encouraging them to try new things, which had led to some wild nights indeed.<br/><br/>All this served to make him more eager to see his sister as he parked the Tank and hurried inside. He pulled open the door and dropped his bag at the base of the main staircase. "I'm back! he called out, heading for the den where his sister usually stayed between getting home from school and going to her room for the night.
