In my mind I ran images of naked women, though mainly my sister, and I wondered how it would feel to be inside her, to make love to her, something Mom probably wouldn't care to let me do, or even know I was thinking.

He had won and she had lost and that was the bottom line. Initially it had just been an argument between siblings but it ultimately turned into a bet over their grade point averages.
