"I wish you couldn't use that stone," Jon said, with a creepy smile.
Suddenly, the stone fell out of Karyn's hands and landed on the floor. She tried to pick it up, but her hands couldn't grasp it. Apparently she couldn't even hold the stone, let alone use it to make wishes.
"Now, I wish it was easier for me to feed on you."
Karyn heard a snarl come from behind her. She turned around and saw Jane, except she wasn't quite herself. She had become a vampire! She grabbed Karyn and held her in place.
"Hm. Not exactly what I was expecting," Jon said. "But, good enough." He smiled, exposing his fangs. Jane opened her mouth wide, revealing her fangs, and joined in with Jon. They both fed on Karyn, until she was dead.
After they were done, they stood up. Jane had some of Karyn's blood dripping from her mouth and Jon pointed it out to her. She quickly licked her lips, sucking up all the tasty blood.
They looked down at Karyn's lifeless body. They didn't care that she was dead. They knew that they should have. What they had done could be considered murder. But they were hungry. And Karyn was there. They saw her as nothing more than an animal. Livestock to be used as food.
Jon looked out the window. The sun was down, meaning they couldn't go outside. Their feast on Karyn was good, but they were still hungry. They wanted more blood.
