"Can you change me too" David asked. "I mean..I've always wanted to be a werewolf."
Andrew bounded over to David and bit him on the arm.
"Ow! What was that for?"
All of a sudden he fell on all fours, howling in pain. His hands and feet grew into paws, his fingernails and toenails lengthened into black, sharp-looking claws. His face pushed out into a muzzle as his ears grew pointed and moved to the top of his head. His teeth sharpened themselves into fangs. Black fur grew from every hair follicle as his muscles grew powerful and he grew in size. His spine ached as a tail pushed its way out of his tail bone. Finally, his eyes changed color to yellow. He howled in triumph and joy as he followed his brother out into the forest. The pack was wailing for them.
The went on a hunt, killing deer and other animals. They howled in delight, rejoicing as the moon shone down upon them, giving them power. At last, they came home as the sun came up. Andrew and David reverted to their human forms.
"Wow...that was exhilarating," Andrew panted.
"Thanks for biting me, bro. I'm happy."
"There's another full moon tonight; we'll transform again."
"I'm happy to be a werewolf," said David. "we'll keep this a secret, alright?"
"Fine with me," agreed David.
"What should we do next?" asked Andrew.
