Big Brothers

The black Family is cracked. A broken home, with broken people, all hurting each other, openly hating and manipulating everyone around them. Sirius long knew he didn't want to be one of the cracks in this crooked family portrait anymore. His parents always fought, his father was barely home. He couldn't remember a time when his mother genuinely smiled or was just content and his brother started walking down a path he didn't want to follow. Nothing kept him there...until one morning his mother suddenly shook the already fragile bond of the family.
Sirius and Regulus were going to be brothers. Big brothers.
Now Sirius found himself in a role he never thought he'd have to be again. A big brother. The only person in this house, responsible enough to take care of a child. He basically raised Regulus, all while raising himself, constantly juggling the responsibility for his brother and the issues his parents bestowed upon them.
Sirius wanted to leave this all behind, yet... what if this time, it worked? Sirius tried his hardest, yet Regulus still turned out just like their parents. But this one? Maybe he could save it...

A story about the lovely home of the noble house of black:) and the question: what if Sirius and Regulus had another sibling? One that was born just when Siri wanted to leave. Is this child gonna be the last drop that breaks the oh so perfect family, or is it perhaps the glue managing to somehow bind them together again? Maybe Regulus and Sirius will find each other again, through raising their sibling. Or maybe they'll lose each other completely...

I hope you, dear reader, have just as much fun with this story as I will hopefully have, writing it:)
