"Okay, just sit tight, honey," Rick said, pulling a syringe out of one of the cabinets. He carefully measured out 100 ccs of the formula, his hands shaking,eager to see the effect it would have on his wife.
Tabitha rolled up her sleeve, clenching and unclenching her fist to make her veins more accesible. Rick gave her a peck on the lips, and then expertly injected the entire syringe into her vein.
Within just a few seconds, the effect was noticeable. "Mmm...Rick...I...I..," Tabitha stammered, panting, running her hands up and down her body. She looked at him with eyes now golden in color, fangs beginning to protrude from her mouth.
Her body began to tremble, and she fell to her knees, tugging at the sweater she wore.
Rick watched with a rapidly growing erection at his wife's throes of animalistic passion as her change continued. She'd torn the sweater off, revealing a swath of blonde fur growing down the center of her back, spreading outward from her popping and bowed spine.
She lifted her ass into the air, and he could see the nub of a tail beginning to form under her skirt, held in by her panties. Thinking to try and help her, he moved closer, lifting her skirt, tugging her panties off to avoid discomfort for her, but the unexpected happened, as it sometimes does to the mad scientists of the world.
As he pulled the panties off, Tabitha backed up, growling, "RRRRick!" in a rough and husky voice. The tail blossomed forth as he pulled them off, lifting immediately into the air and he was hit with a spray of fine mist from her reshaping hindquarters.
Rick fell backward, feeling his inner body temperature rising. The spray smelled not so much like a woman's scent,or a beasts, but rather the formula! A high dosage injection would actually cause a female to reproduce the formula in her musk! Rick was aware of the itching on his chest, and the knot in his pants. Though he wanted to document this in his notes, feral urges were replacing scientific ones in his mind.
Unable to hold his beast nature inside, he tore off his clothes, eager to please the bitch on his floor. He began to lick at her vagina from behind, eagerly consuming more of the chemicals in her musk. Tabitha's growls, which had been of relatively low volume, grew rapidly in intensity and volume, as her change sped up.
Her delicately manicured nails had now become jet-black talons, and her soft, white skin covered with a blonde, rough fur. Her ears now pointed through her hair, and her face began to push forward into a leathery muzzle. Four newly formed breasts began to waggle in time with the other two as Rick plunged into her, unable to simply stick to foreplay, and they were locked in a mating rut, still shifting, their howls building to a crescendo that coincided with Rick's seed spurting into her.
The Rick-wolf slipped back out of Tabitha, who turned to face him. The contrast in their appearances was striking. Tabitha was simply a large, four legged wolf, with vaguely humanoid characteristics; namely the breasts. Rick, on the other hand, was definitely human looking, albeit with almost a neanderthal cast to him. His forehead was thicker, and his teeth were elongated, and his jaw jutted forward slightly. He was also covered with hair. He looked more like the Wolfman character from the old black and white movies, whereas his wife looked more like something from "An American Werewolf in London".
The other striking difference between them was the duration of the change. Even as they stared at one another, Rick's fur began to recede, and within a five minute period, he was back to being himself. Tabitha, however was still as beastly as ever. "Tabitha, this is amazing!" he said excitedly to the wolf. "Do you realize what this means?" Rick leapt excitedly to his feet, wanting to note this in his journal. But his sudden movement had triggered an unexpected reaction. A low growl came from Tabitha who advanced on him slowly, ears back and head low. "Tabitha....calm down.." he said, trying to control his fear.
