Write down "To heal my body"

You grab you pencil and write down "My body was fully healed" you were testing if my will lead to yourself or just some random person. The moment you finish writing a green light surrounded you and you felt great even better then great you felt like you can run a marathon. So this book was magic and anything i write in it will come true. You think to yourself "this is aswome i could do anything i wanted". But you calmed yourself down you don't want to become a god you just want to get back at the people who hurt you while also having a little fun yourself.

Then you got a idea in your head that any teenage boy would have. You wrote down " When hard my did would got to nine inches and soft four inches long" and when you finished the sentence you penis grew to the exact size you wrote down. This is awesome i can have a enjoyable li.. and just before you finish your sentence you hear your sister banging on your door. It surprised you but you got use to it she was yelling "Pervert get out here and clean up this mess now or I'm going to tell all my friends that you watch me in the shower". that was not true in the slightest then you got a great idea will this work on people.
