You still live at your mother's- even though are an adult- even then you still have to follow her rules or get punished. Your mother has a very old-fashioned sense of punishment: Brats need a good old whooping. She is not shy spanking you for breaking her rules and quite hard too. You are in trouble BIG trouble and you are waiting inside your room awaiting your impending punishment. The belt? The switch? Hairbrush? Or all of them she will decide.

Message one should be more roleplay while message two should be more interactive story. Both will be a similar scenario.
