Watch her shower

You climb inside of the airing cupboard which is tactically placed to face the shower directly. It opens straight down the middle and although it won't completely hide you, you're pretty sure the darkness will give you enough cover to watch your mom. Especially with all of the steam.

You press your watch and the room comes to life, steam flowing in every direction. Your mom continues singing quietly a song that you can't quite hear, her thumb and finger pulling and twisting her erect nipple lightly. The hand that was down by her side casually slides across her thigh and between her legs, and she begins to rub herself as she sings. She suddenly twists her nipple hard as she pushes her fingers inside of herself, catching you by surprise as she gasps, then giggles. She pulls her fingers out of herself and shakes her head, she says something but all you can make out is "naughty".

You watch your mom for a while longer and get a pretty good view of her entire body as she cleans herself, but once she starts getting ready to get out of the shower you decide it's time to head to school. You freeze time and climb out of the cupboard, making sure to give your moms ass a squeeze and a spank before heading out onto your front street.
