Peeking at my sister

When my younger sister would go to take a shower , I would peel at her. We had a water pump room accessible from the outside. It has a 8x10” opening to allow heat transfer. I was able to watch her undress , dry off and redress daily. After I watched her leave the bathroom I would go inside get her dirty ** from the hamper and ** off. She had blinding hair and her ** hair was dark.
