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, 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 this 'little sister empties balls story' is about as the title is rather ambiguous. It could potentially be about a little sister emptying some kind of ball - like perhaps emptying a ball of yarn or something similar.
Since I don't know the 'little sister empties balls story', I can't give more details. It could be a very unique story in a particular book or told by someone, but without further knowledge, there's not much more to say.
As I don't know the actual story, I can't determine its significance. It could be significant within a certain group of people who created or know the story well. Maybe it has a moral about family relationships if the little sister is a central character in a story with some kind of plot related to these 'blue balls'.
I haven't heard of the 'Little Sister Blue Balls Story' before. It could be a very unique and local story. It might be about a little sister and something related to blue balls, but again, without further details, it's impossible to share the story accurately.
Since the 'bj' in your title seems out of place and not clear in relation to the 'little sister swallows seed' part, I'll focus on the main part. It could be that the little sister swallowing the seed is a key event in a story about a family. Maybe it causes worry among her family members, and they have to figure out what to do, like whether to take her to a doctor or wait to see if it passes naturally.
