“Ahh Jen, you were perfect.” He said reaching into his pocket. “And I have your reward right here…”
Saying this, he pulled out an dog whistle from his pocket, it's metal body glimmering silvery in the dim hue of the street lights that managed to slightly enlighten the twilight of the alley the girls and the mysterious men were standing in.
"See, we're scientists and being that, we tried to further the evolution of the human species," the man grinned, his canines seemed longer than what would be normal, "and as we all know, humans can't work together properly. All the constant bickering, the infighting, the rivalries and the hate..."
The man slowly turned the whistle in his hand, looking at it, while the frightened girls huddled together, still slowly changing. Some of the later infected girls were slowly growing tails and fur, while Jens' body was already nearly covered in a thin layer of fur, her pointy ears moving to catch any sounds.
"To stop the constant fighting" the man continues his speech while observing the slow transformation of the girls into whatever dog-like creatures they would become with a wicked grin, "we tried to come up with a formula to bond human and canine genes. We hoped that this would infuse the humans with a bigger understanding of pack mechanics and a deeper love for the simpler, more natural things. We all took a dose of our formula..."
The mysterious man waved for one of the other two burly men that blocked the alley. "Show 'em!"
Jen and her friends whimpered in fear as they observed what the burly man unveiled, as he unzipped his fly and released his dick to the cold night air. It was gruesome, as it wasn't human. It was glistening red and pointed and proudly possessed a huge knot at it's base. It was a canine, a dogs' dick!
Jen tried to turn away from the gruesome sight, but something inside of her battled her human thoughts of fear and instead infused her with a warm and pulsating lust that originated deep within her neither regions.
Dumbstruck, Jen could do nothing but stare lustily at the canine cock in front of her and her friends and only partially noticed that the other girls were unable to turn away from the sight, too.
"See, we were all transformed in some kind of way. Physically and mentally, I have to add," the mysterious man continued while unzipping his fly and releasing his own huge dog cock.
"But, as I said, we are scientists and we came up with this little nifty device that would grant us powers over lower tiers of transformees, as you are. See, you're all infected with a slightly diluted formula of what we guys took. We're able to transform into our new forms at will, as you will all observe very soon, with the minor exception of our cocks which will stay canine at all times."
Jen, now fully covered in fur, felt herself flooded with a strange animalistic lust as her dog-like nose smelled the mating-ready canine cocks and she felt that her still transforming pack-sisters were encountering the same emotions.
With a whimper, Jen started to shed the remains of her clothes and stepped into the night as a perfect hybrid of human and dog: fur, teeth, tail, muzzle, claws, digit-grade legs and paw-like feet. The only thing clearly human about her remained her long blond hair that flowed down her fur-covered back like a mane. Her animal eyes glimmered in the alleys' twilight.
"I see, we have a new test subject," the mysterious man slowly growled, while his teeth started to grow pointed, "and now we will see if she obeys the whistle..."
