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.
Since the terms are rather ambiguous, it's difficult to say what this story entails. 'Big brothers' might imply siblings, 'baby juice' could be something related to a baby's drink in a story about taking care of a baby perhaps, and'sister' is another family - related term. However, without more context, the overall 'big brothers baby juice sister bj story' remains a mystery.
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.
If this is a non - inappropriate story, perhaps the 'trick' could be a misunderstanding. For example, the little sister might be tricked into believing she's going to a fun party but ends up at a boring family gathering. It could be about how she overcomes the disappointment and finds something positive in the situation.
Well, 'big brothers' usually refers to older brothers in a family. 'Baby juice' may refer to a liquid, perhaps milk or some kind of infant formula in a story about a baby. 'Sister' is self - explanatory as a female family member. But 'bj' is a mystery here. It could be initials of a person, or some special term within a very specific story that we don't have enough information about.
She could forgive the person who tricked her and they become closer friends. For example, if it was a sibling who tricked her out of a bit of mischief, she realizes it was all in good fun and they share a laugh about it in the end.
I'm not sure what specific 'BJ' means in this context. If 'BJ' stands for Beijing, here is a story. There were two sisters in Beijing. The older sister was very kind and hard - working. She worked part - time while studying to support her younger sister's education. They often shared their dreams and supported each other through difficulties in the big city.
Well, once when babysitting my little sister, we decided to have a pretend tea party. I made her 'fancy' tea with lots of pretend cream and sugar. She then started to sing a made - up song about being a princess at the tea party. It was so hilarious as she made up these wild lyrics. We ended up dancing around the living room with our tea cups in hand.
