You look to your left. Out of the dark canopy shadows the trees make, another enormous werewolf steps, growling lowly. You hear another one behind you and know there's another one behind you. The same on your right.
Trembling, the wolves all close in. You sob in despair and are about to accept your fate when you feel a tingling in your hand. Looking down, you raise your hand up to the moonlight and look in horror as you see your fingers elongating and growing sharp, six inch long claws. Thick grayish-white fur has grown where you scratched yourself on the werewolf fangs and it's spreading. Quickly. You feel a tingling your other hand look down to see the same thing is happening there as well.
The werewolves take a step back when they see this, and look at each other, as if saying "This isn't going according to plan..."
Your shoes feel very tight and you look down just in time to see them bulge and rip off, revealing two gigantic three-toed paws with black claws on the end, all covered with that same thick grayish-white fur. Your feet elongate and your pants feel very tight as well. They get tighter and tighter until they rip into ribbons, revealing your legs have grown gigantic with bulging muscles and thick grayish-white fur. Your thighs bend away, looking like a wolf's legs. The fur rapidly spreads itself up your stomach and around your back, covering your butt. Your pecs and stomach muscles bloat out rapidly, become very muscular. The fur covers your chest, stomach, and back quickly. Your biceps and forearms bulge with muscle as well, as your front "paws" grow larger to accommodate your increasing size. Your spine lengthens slowly and you look down and see you're nine feet tall as well. Your back hunches over and your shirt finally rips off, revealing your muscular, furry broad back. Your neck bulges with muscle and thickens and pushes your head outward. Your face pushes out into a long muzzle, and you feel your teeth growing not sharp wolf fangs. The fur covers your face and your eyes turn yellow as your nose turns wet and dark. Your ears travel to the top of your massive head and grow pointed and furry. The fur finally finishes sweeping your body as it come to the top of your head. Your muscles all over your body grow larger for a few more seconds, then a huge, thick wolf tail bursts from your rump. You feel savage and powerful. Leaning back and throwing your head up to the full moon, you howl a howl that could probably be heard from four or five miles away. You start breathing heavily and lean down, eyes flitting to all the other werewolves.
