Well, without more context, it's difficult to say precisely. It could potentially be a story where two brothers have something to do with large spherical objects. Maybe they found big balls in an attic and it led to a discovery of some family secret or it could be a comical story about two brothers who are clumsy with large balls in a game or activity.
I'm not sure specifically as I haven't heard of this exact 'big brothers heavy balls story' before. It could be a very unique or local story. Maybe it's about a big brother who has some sort of adventure related to heavy balls, perhaps in a game or a strange situation.

The little sister is likely a young, curious girl. The big brothers could be teenagers or young adults. There might be a neighbor kid who is sometimes involved, perhaps a bit jealous of the relationship the little sister has with her big brothers and their 'big balls'. This neighbor kid could add some conflict or comical situations to the story, while the core relationship remains between the sister and her brothers.
There are two brothers, Alex and David. Alex was passionate about painting but was shy about showing his work. David, his brother, encouraged him to participate in a local art exhibition. Alex was hesitant at first but with David's constant support and motivation, he finally entered. Alex's paintings were a hit at the exhibition, and the two brothers celebrated their success together. This story shows how brothers can support and inspire each other.

It could be that the 'balls' are some sort of toy balls. The sister might be curious about what her big brother is doing with his collection of toy balls and starts playing with them. For example, they could be bouncy balls and they are seeing who can bounce the ball the highest or the most times.
