You flipped to the page about dragons, and began to read while looking at the picture of the dragon in the book. You put your hand on the print for a brief moment, and took it off to find something strange was happening to it. Suddenly your hand changed looking more like a giant claw, and you lost your thumb too as your nails grew to match that of a claw. Green scales then started spreading across your body, and your body's bone structure changed all at once giving you a muzzle, and your body suddenly became resemblant to that of a dragon. The scales continue to spread as you grew wings and a tail, both extremely painful to grow. Finally as the scales finished spreading you saw your dick split into two different dicks, and retreat into a sheath beneath your scales.
"What the...." You began, but stopped considering how deep, and loud your voice became. You began re-reading the book, and found out two things that interested you. First was that dragons were intelligent, and had a lifetime much longer than humans, and could even communicate with humans. Second was that male dragons had a lot of pride, and often asserted themselves over any female dragons that they came across. It was a good thing you weren't female.......right?
