yes if they are related

Maybe they are bored of the same sex and do things different
Well, yes and no. Yes in the sense that it is more than possible to have the connection and relationship with your god sisters that blood sisters (sisters related by blood) have. However, if what you're looking for is a sister in the sense of having the same parents and such, well, that's not really possible. But to be honest, when is comes to sisters or brothers it's the connection that you have with one another that matters. There are many people out that who have better relations with "brothers and sisters" who aren't related than with those who are. Make sense?
If they are brothers or sisters
