Suddenly, Jack felt his whole body warm up and start to itch, his arousal increasing dramatically. "Oh fuck. Guess that part of the wish didn't work..."
He quickly starts removing all the clothing that was on his body, sweat coating his skin and his 6 inch cock fully erect and throbbing. "Ah no!...I was su-suppose to observe the virus, not join them!"
Jack growls and drools, strings and globs of saliva dropping to the floor as some of it lands on his chest. Black fur begins to sprout all over his body, his feet contorting and shifting into bipedal wolf paws. He pants and groans, trying to resist as much as he could...but it was a hopeless fight.
"Haha..HahAHA FUUUUCK!! I CAN'T CONTROL MYSELF!!" Jack strokes himself after his hands turn into claws, his body now being a foot taller than it was before and muscles more toned. His face begins to slowly expand into a wolf's, his teeth becoming sharper as more saliva drips from his mouth. Finally, his cock morphs into a wolf's cock, the base growing into a knot and the skin color turning dark red. "GGRRRRRRRRRRRR AAWWWOOOOOOOOO!!!"
Jack howls loudly and cums, shooting thick ropes of wolf jizz all over the window in front of him. All his rational human thoughts were gone, and were replace by those of a werewolf. He smiles and snarls, his intstincts telling him to leave the house. Going down stairs and tearing the door off its hinges with his new strength, Jack made a choice to either breed with the other werewolves or find some humans who haven't turned yet.
