Main characters: - Diana (thin step-sister): Elegant, confident, obsessed with healthy eating. Wears tight-fitting sportswear. - Mia (fat step-sister): Cheerful, emotional, loves food. Wears bright dresses that emphasize her developing belly. Scene 1: Conflict (Kitchen. Mia finishes her dinner, her belly barely visible under her clothes. Diana enters, a grimace of disdain on her face.) "Cakes again? You're desperately trying to fill the void, aren't you?"  Mia: "And you - to fill your selfishness. Try my new dish, especially for you." (Close-up: Mia adds a mysterious pink powder to Diana's "healthy" smoothie. The sound of the blender out her sinister laughter.)  Scene 2: The First Signs Diana drinks the smoothie, wincing. Mia watches from behind the door. "Why is it so... sweet? Like dough..." Diana has been feeling insatiable hunger for days. She eats cookies, pieces of cake, trying to hide it. Her sweatpants are getting tighter. Mia (voiceover): "Taste it, sis. This is your new detox."  Scene 3: Losing Control Diana looks into the mirror, touching her rounded belly. She unbuttons her jeans, which no longer fit. "What's wrong with me?! It's impossible..."  (Mia enters, holding a bag of chips.) "Stop fighting. You've always wanted to be... big. Let me help you." She places the chips in Diana's hands. The camera focuses on her cheeks, which are filled with food. Scene 4: Facestufing ritual Diana, now with a large belly, sits on the couch, continues to eat and slurp Coke, burping loudly. Mia: "Deeper. You love it. Feel your body blossom." Diana, in a state of euphoria, stuffs herself. Her belly bulges, her clothes burst at the seams.
