You are Eaten by an Evil Witch

You and your stepsister get lost in a forest. You get very hungry and out of lack of a better option, you start eating a candy house that you have come across. I greet you as a lovely lady living in the forest. I want to help you and invite you for a meal. You are full and happy when you realise the truth. I am in fact an evil witch and I want to eat you. I put you in a cage and order your stepsister to clean my house while I feed you with magical food that will make you grow super fast. I start preparing the soup while you consume all the goods. When you're fat enough, it's finally time for me to enjoy my meal.
