Peeking at them, I knew right away what I wanted. Jack had always had pretty girlfriends, and they all ended up in the same three positions. First they were happy he brought them home. Then they were naked, and covered in sweat as he pounded into them with wild abandonment. They thought this was passion, but I knew better.  Jack was making himself immortal. He made sure that each girl he conquered never forgot him, or what he put their frail bodies through.

I think it was, that the women gave him everything they had during sex that made their final position hurt so much. Even more than the anal, and that looked downright torturous.  

Usually, Jack fucked them two or three more times in every way possible, and then dumped them for a new conquest. They would cry and ask why, but Jack would only laugh at their tears, before driving away. Their last position was standing in the street sobbing, as they looked into the green eyes of his little brother, and then walking away shamed and broken.

Yes, I knew right away, I wanted to be nothing like Jack. I wanted to be a man.
