Your stepsister knows what you’ve been doing... hiding her deodorant so she smells more, watching her armpits like a perv when she reaches to take something out of a cupboard. You love her hairy armpits-- you’re obsessed. You love the smell of her pits, and she catches on that you like her other smells too. Her feet, and even... yes, her ass. She teases you and turns you into a toilet slave. She’ll take a dump right in your mouth and you’ll eat it. And you love it.
