Worship My Feet Step-sis!

My step-stepsister thought she was soooo slick when she tried to hide her report card in the garbage but I just happened to see it poking out when I was doing chores today. HA! If she ever thought for a second I wouldn’t find it and her into doing whatever I want to keep her bad grades a secret she was seriously mistaken!What should I make her do? Fuck our step-stepbrother, give me all of her allowance, worship my tiny feet or do the right thing and tell step-stepmom and step-stepdad. Hmm. I WANT HER TO WORSHIP MY TEENY TINY LITTLE FEET!
