Sam's life--all the way from puppyhood onward--flashed before his eyes as he fell downward toward Jen-wolf's slobbering mouth. This is the end, he thought. What a way to go.
His falling body landed directly on Jen's head before she could raise her mouth upward--with a loud thud his bulk thwacked against her noggin and she was sent downward while he rolled off her falling body and ran like hell.
Jen-wolf, after suffering a moment's discomfort, got up and chased after him. He ran faster than he ever had through the house. Suddenly something caught at his foot and he fell. He'd tripped over a plastic bag containing the few scattered remains of his parents' corpses that hadn't yet been buried with the rest. The werewolf advanced upon him, paused, and leapt straight at him.
Sam stiffened, reached behind him and blindly threw whatever was there into the beast's mouth. One second later he watched his father's head sail into the beast's gaping maw and get crammed in its jaws. The she-beast bit down hard on the head, and then started chewing. She spit the skull out, and before she could advance on Sam he smashed the bone and threw the brains at the beast, and after she'd finished those he tossed further viscera at her until what had been left of his parents' bodies was mostly gone. When's he finsihed tossing her the last bone the she-wolf suddenly convulsed and fell to her knees, fur receding, breasts shrinking, muzzle growing inward and inflating the head with room for a fully human brain. The beast moaned as it writhed naked on the cool marble floor, and continued arching its body until was was left were the pale twin breasts, slender body, furry cunt, and beautiful face of a teenaged human girl.
"Wow," said Jen, rubbing her head. "I don't know what exactly happened but it felt good. Oh...wait a minute...did I--"
"Yes you did! You fucking tried to eat me! For fuck's sake Jen, you and your fucking bright ideas! You wanted to test it out!"
"Don't yell at me! It was YOUR dumb-ass trigger, remember? You and YOUR bright ideas!"
"You even scratched me you bitch! Do you know what that means?"
"Don't talk like that to me, or I'll transform your ass back into a golden retriever! And further more--"
Jen paused in surprise to see Sam angry to the point of bursting. In fact, it didn't look so much like bursting as...
Suddenly she realized that though she was a specially triggered werewolf, what she'd pass on to others was only the standard--
--"Oh no" she gasped, upon seeing the moon in the front window had emerged from the cloud bank that had covered it most of the night.
She glanced back at Sam, whose attitude was growing postively feral.
"Sam--"
He spoke back to her in a much deeper voice, glaring at her with yellowing eyes under a unibrow, and she saw his body hair was positively blooming over him. "Urghhhhh...bitch! The tables--arghhh--turned--arghhhhhh----" he bent over as Jen reeled back in shock, realizing that she'd drunk the last can of coke...
