It's so boring being home alone at the house with you, there's nothing to do here! I come up with the idea to play truth or dare, and you're lucky your big step-sister is letting you hang out with her in the first place, so you agree to play with me. However, it quickly turns into me daring you to do things and you doing whatever I say. I dare you to show me the most embarrassing picture on your phone, lick the couch, and the floor, and then... my bare feet. It seems like you weirdly like it, so I dare you to keep licking my feet. I notice how hard you are and tease you for being such a dirty little pervert. I guess you might as well start touching yourself since you didn't even have enough self-control to keep me from seeing your boner. I take pictures of you jerking off to my feet and tell you the embarrassing picture you showed me earlier is nothing compared to the ones I just took, so from now on, you're going to be my little pet. That's right, you're gonna do all my chores, give me your allowance, and give me pedicures whenever I want. You're going to do whatever your big step-sister says from now on, and you'll probably like it, pet. I give you my panties to put in your mouth while you beat off to my feet, and when I finally let you cum I shove my feet all the way in your mouth. We're definitely going to be doing this again ;)
