A different idea came to Jack, he smiled a little to himself, knowing that this was perfect. "I wish for a virus that infects the entire population save myself unless I wish otherwise," he said, then started to map out exactly what he wanted. "The virus will be transmitted through sex and contact with infected body fluid, and will have an incubation period of 3 days, during which an infected individual will begin to become more sexually active as well as lose all their inhibitions, causing them to do sexual acts that they would not normally do. After 3 days, they transform into a combination of a human and a wolf that combines the best traits of both such as bipedal movement as well as the senses and basic appearance of a wolf and that they keep the heightened sexual aggression, while maintaining some semblance of human intelligence. I also wish that it is already 3 days into the outbreak and that the disease has spread worldwide so that people are already starting to change."
As Jack finished his wish, the wave of magic spreads out across the world from his ring. He went to the window, curious to see if anyone was beginning to change yet. He smiles a little, noticing a girl and her boyfriend shedding their clothing as their transformations began as in full view of everyone the boyfriend mounts the girl as fur spread across their bodies. Not caring who saw them, the two changing teenagers barely notice as their bodies transform, Jack smiled, they where starting to enjoy it even. The transformation finishes as their tails burst out and their faces push out into muzzles as the two werewolves let out long howls, which where soon joined by more from around town.
The werewolf virus had begun.
