Yes that's another "curse" type story. But hey it's a special one !
Someone must have really annoyed a powerful being. This day, a guy (we'll call him Chaz) was chilling at home, not doing anything as he usually do when he gets back from college. Studying is for the weak y'know. Chaz finally turned on the TV and a rather stupid quizz show appeared. He quickly changed to something "smarter". Here you go, a documentary about science and nature.
But then, as a not so unexpected plot-twist, a robotic voice in his head came out of nowhere and told him "You have been cursed because I want you to stop doing nothing. Yep just for this. Take it easy, it's not all that bad... you'll see, it's fun. You will now get changes based on what arouses you. It can be size change, body swap etc... for instance if you see a guy and unintentionally think just for a second about how big his bulge is your dick will grow a little. But I'm watching you, it's only unintentionally, no cheating. If it's an opposite gender it will act as if your body grows (or shrinks) that part. The change is about, let's say for now, 10% of size or gender type. But it can affect your entire body, like almost body-swap or gender change. Yes I'm a little twisted but I have fun so you don't need to ask questions. Bye bye ".
What in the world was that, Chaz asks himself. Too much junk-food must make you hear weird things. But it's only the beginning of the journey of our average dude (he's like 20, 5'11").
