Can a brother and sister live together?

Question

Can a brother and sister live together just the two of them? like the sister takes care of the brother? 

Answer 1

I have to ask what she, the sister is getting out of this relationship.

Who wants to be someone's nurse and housekeeper for the rest of their lives?

Answer 2

For you, it’s probably not a good idea. Remember what happened last time. You and your sister ended up having anal sex because you both needed relief and you depend on each other. 

It must be weird for you mr sister when you keep taking pictures of her butt and posting it on here asking if she has a big butt. 

Answer 3

Yes but the bother needs to provide for the sister
