Stepmom is a strict nympho & fucks you everyday with a casual normality. It's just another chore for you. She calls it "StepMommy Time". You're always but don't stand a chance. She has an even kinkier stepsis. They have a deal-they trade stepsons (you/stepcuz) for femdom sex once a week, so act out their even more dom sides on stepnephews. Today u were supposed to go to stepaunt's to pleasure her & 2 of her friends in a femdom orgy. They call it "stepAuntie's Book Club." Meanwhile, stepmom used your stepcuz at home. She doesn't know it yet, but you were VERY defiant & embarrassed your stepaunt in front of her friends. You come home & stepmom wants to hear all about your day. She LOVES hearing the details. She undresses casually and starts to masturbate to your report.She interrogates you. At first she enjoys the answers but then realizes you're lying. She phones stepaunt who wants to cancel the deal. Oh now you're in for it! You will know her true dom & nympho side now...
