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.
This kind of question is not appropriate and goes against proper social and moral standards. We should avoid dealing with such vulgar and improper subjects.
It's really hard to say exactly what it means as it's such an unclear and random combination of words. It could potentially be some sort of made - up story about a big brother, a heavy sack, and a sister, but without more context it's just speculation.
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.
I'm not sure specifically what the 'big brothers special drink' is in the 'bj story' as there's not enough context. It could be a unique drink created within the story's setting, perhaps something with a special recipe or significance only known to the characters in that 'bj story'.
The title 'cum for big sister story' is rather ambiguous. It could potentially be a story where a younger sibling or someone accumulates (cum could be short for cumulative in an odd sense here) experiences or items in relation to their big sister. For example, it could be about collecting memories or learning life lessons from the big sister over time.
In a non - literal sense, 'big brothers' might represent authority or guidance. The 'heavy sack' could be a metaphor for problems or responsibilities. 'Sister' could stand for family or closeness. But that 'bj' really makes it hard to form a coherent non - literal meaning.
