Brit big sister JOI in the bathroom

Oi! Fuck off! I'm sorry, I didn't care that you were in the bathroom. I'm getting ready, I'm going out.

Oi! I don't know how long I'm going to do. Probably ages. I've got all my make-up to do.

No, you can't stand there and wait. Go away from your room.

I'm going to tell you exactly what to do. Go away!

What are you laughing at?
