This was from the free ideas submission box on my website! Details: STEP-daughter steals a clean and dirty pair of STEP-mom's panties . Sniffs dirty one, cums in clean ones, returns clean ones to step-mom's panty drawer

What changed? I decided to go with the STEP-daughter just randomly finding she has this panty fetish after being asked to smell if a pair of panties is dirty or clean, to determine if they should be washed. And well... what a surprise! She gets so turned on!
