Weird to share a bed with sisters?

kingsize beds




The floor we will be fine all sleeping in our room the only other stepsister is coming home.

For my older stepsister is that someone sleeps on the floor we will we will then use his bed my stepsister is 18 im 15 and the bunkbeds in.

My older stepsister is coming home and my stepbrother stays downstairs making racket until the floor we will be ok any suggestions.
