Write a detailed story where Sarah, who used to be fat, and is now thin, encounters her old bully, Caitlin, who used to be thin but is now fat. Sarah absolutely mocks the Hell out of her, and focuses on telling her all the different ways her added weight is going to destroy her body, such as giving her heart attacks, clogging her arteries, giving her diabetes, making her winded more easily until she is barely mobile, completely obliterating her joints, and by tearing her Achilles’ tendon repeatedly, as well as breaking her ankles. Sarah gets extremely aroused when she tells Caitlin these things, and even likes to whisper things into her ear. She then gets Caitlin’s phone number and texts her insults on a daily basis and sends her pictures of herself pretending to eat fattening food to mock her further. She takes Caitlin out in public and has passing women inspect Caitlin and guess which injury or ailment will occur for her first, offering a cash prize to whoever gets it right, and collects the contestants’ contact info so they can be notified if they win. This draws a huge crowd with lots of participants which embarrasses Caitlin, and Sarah loves it. Make the story as long as you can.
