There's really not enough information in the title 'little sister empties balls bj story' to accurately determine what the story is about. It could be part of a creative writing exercise where the words have a very unique and personal meaning to the author. It might also be a mis - named or mis - remembered story title. Without further details, we can only wonder what it could be.
Well, if we assume 'bj' is a place, here's a story. The naive little daughter, Amy, lived in a small town. One day, she heard about a wonderful event happening in bj. She was so excited that she begged her parents to take her there. Her parents finally agreed. When they arrived in bj, Amy was amazed by all the new things she saw. She made new friends and learned about different cultures. It was a great adventure for her and she grew up a bit more worldly after that experience.
Well, let's break it down. If 'little sister' is the main character, and 'empties balls' could mean she is taking balls out of something, like a box or a bag. But 'bj' is really throwing me off. Maybe it's the initials of a place or another character. So a possible plot could be that the little sister is helping to set up a ball - related event. She empties the balls from storage and then has to wait for someone named BJ to arrive to start the activity. But again, this is all speculation given the very odd and unclear title.
I'm not sure specifically what the 'little daughter bj story' is. It could be a very personal or local story. Maybe it's about a little daughter in a place named BJ, but without more context, it's hard to say more.
I'm not entirely sure what this specific phrase means as it's rather unclear. It could potentially be some sort of very specific or made - up story reference, but without more context it's difficult to define precisely.
