Karen stared up at the night sky, concentrating on the moon, still barely a sliver in the darkness. A familiar heat began inside of her; she could feel her body temperature rising. This was how it always started.
On a normal night, this little moonlight wouldn't have hardly any effect on her at all. But this night was different; this night she WANTED it to. She concentrated on the moonlight, urging it to fill her with its energy. She began to hyperventilate in order to raise her pulse rate, to urge the beastial side of herself forward.
She dropped to the ground, the grass slightly cool on her bare ass as she lay on her back, never taking her eyes off of the moon. Her nipples were rock hard and erect now, and her shaven muff began to glisten with the first few drops of the moisture of arousal. The change was almost upon her.
Karen was at the watershed point; she could pull back from the change if she wanted to. She could put her clothing back on and drive home, resume her normal human life, forget the Triad and the city's problems, she knew. This was the temptation she always faced, the inner voice that always spoke in her head whenever she induced her change. And every time, she had denied the inner voice, for she knew what she was doing was for the greater good. Tonight was no different.
With a trembling hand, she began to massage herself, splaying her lips ever so slightly, rubbing her clit gently in the moonlight. She gasped as the first few strands of golden fur blossomed from her crotch, in response to her tentative touch. Her body felt like it was consumed in a fire of sensuality, burning hot, yet in an undeniably pleasurable way.
Karen began to moan now, rubbing herself more firmly, more vigorously, urging the change on. Her thighs now were covered in a golden coat, which had spread forth from her groin. Her body shuddered as it gained in muscle mass, her arms and legs bulging with new muscle.
Her torso popped and shuddered as her breasts grew larger, and two more sets, both smaller than the first, grew underneath. "Hrrrrgghhhoooooooo.." growl-moaned Karen, to whom each muscle twitch, each blossoming hair was like a miniature orgasm. She now was madly masturbating, thrusting her pelvis up towards the moon with each thrust of her fingertips.
Black talons now ripped from her nail beds on both her feet and her hands, which had also developed calloused pads. She rolled onto her stomach, then onto all fours as her spine bowed and snapped slightly, and a wet, furred tail blossomed from her ass. Undeterred, she began to rub her slit and ass against the bumper of the car, still trying to satisfy herself. Still transfixed by the moon, her face stretched into a muzzle, dripping spittle from a fang-filled mouth, as her ears pointed and pushed upward. Her eyes now glistened a burning yellow, and with a final howl of orgasm, she stood.
She was no longer Karen, she was the beast. She was a fully bipedal golden werewolf, undeniably female, undeniably deadly.
She was the thing that made mortals tremble. She was Klaw, the identity she'd given herself when she first mastered control of the change.
She now saw the lights of an approaching boat, headed for the docks.
