Your younger stepsister is super freaking annoying and whiny, especially when she is sick with a cold. And of course, while your parents are on vacation, you are left in charge of her, instructed to cater to her every need. Great. The last thing you want to do while the parents are out of town is serve your stepsister chicken noodle soup. The least she could do is say "please" and "thank you", but instead she just makes irritating demands and threatens to tell your parents about how much money you've spent on eBay with your parents emergency-only credit card! You've got a plan though. All of your stepsister's moaning and whining and nagging has REALLY got to end; you've finally gotten her something for her to take to help her battle this cold of hers. Something you bought off the internet--some rather strange-looking, strange smelling herbal elixir. She gulps down the gross fluid and dozes off!

Upon waking, though, things seem strangely different to her!  Has her bed gotten smaller... or has she gotten bigger?  And what happened to her pajamas? She is now wearing her school uniform, and it's like way-too-small for some reason! Your stepsister calls for you, and you are pleasantly surprised to hear that her squeaky, whiny voice has been replaced with a voice that matches her now more curvy and voluptuous body! You encourage her to down more of that magical cough syrup, eager to see what new changes will occur! Your stepsister is easily convinced when you agree to pay her $50 and do all of her chores. Gulp, gulp. Her boobs grow huge! Gulp. Her hair grows long. Gulp, gulp, gulp. Makeup, a big, round ass, and long legs appear before you! Before you know it, your stepsister is super sexy and wearing only a tiny bikini! She assesses all of her new attributes, quickly becoming very pleased, very confident, very seductive!  She realizes that her stepbrother is completely putty in her hands, and she's going to have some fun at his expense. She easily mesmerizes him with her words and body. Once she knows she has him at the height of ecstasy, she
finishes him off... "You think I'd satisfy you, after how you EXPERIMENTED with me?  I wish you were young and sick, so you would have a clue as to how it feels!"  And oddly enough, he starts becoming younger... and smaller... and sick with a cold! She can't stop laughing at his predicament at first, but soon realizes, not only is she the most gorgeous girl in town, but also the most POWERFUL as well!  Is it possible that whatever she wishes... becomes true?! She wishes herself into a smoking hot club dress!  Now she is ready to take over the town!
