The whistle is insistant. You growl in anger. Your secret admirer turned you into a dog, and now she's expecting you to come when she blows her whistle. You squat down on your haunches, but then the whistle blows again, and you're up on your feet. The whistle is calling you, it's commanding you to come. You trot over to the door, and stare at the secured door. Even if you could leap up and manage to turn the doorknob, there's no way you can undo the security chain. The whistle calls. Your primitive mind screams go to your master.
Your diminishing human mind argues maybe you should go, and find out who did this to you, so you can get changed back. It too is being compelled by the spell of the whistle. You run around the house barking looking for an exit. You spot an open window and leap out it ripping the screen out of the frame. You land on your forepaws and dash toward the park. Part of you feels embarrassed as you gallop naked down a public street. Everyone can see you. You just run faster. The human part of your mind does remember that you are or at least were wearing a jockstrap, but you also can feel the wind racing by your exposed malehood. You're no longer thinking of yourself as a man that has been changed into a dog. You're thinking of yourself as a dog that once was human. It's a small, but important distinction.
You overshoot the entrance to the park, and skid to a stop, and trot back to the entrance. Your nose is being overwhelmed by all the scents you're smelling and cataloguing in your canine mind. You slow to a trot trying to determine who blew the whistle. Who is your mistress? There is a group of cheerleaders practicing in the park, maybe one of them? You stare trying to guess which one. Is it Stacy the blonde? Zia the short one? Nikki the busty one? Or-? The whistle blows again, it's not the cheerleaders. You run toward the hedges where the sound originated.
Bursting through the bushes you find an old abandoned fountain, and see the back of a shrimpy guy in oversized clothes. He blows the whistle again. You bolt over and leap up on your master's shirt sending him backwards on to the ground.
"Haha, Bruno! Down, boy!" he laughs rubbing you with his hands. He strokes your furry body as you nuzzle him. You feel his fingers slip under your skin and he pulls the jockstrap off you. It feels odd as it peels off your body leaving a twin of the black dog shealth that it was. He holds the jockstrap that now looks like a dog's genitalia on a strap instead of a pouch. He pulls down his cargo shorts and he's naked. You continue to sniff his crotch, and he laughs.
He turns the jockstrap inside out, and steps into it. Your eyes widen, as the jockstrap changes into human male genitalia. It's larger and than the shrimp's cock and it's cut, like yours used to be. As you watch, the dark wiry little guy starts to grow. His oversize t-shirt is now up above his belly button. His skin is lightening. You watch as the growing guy's outtie belly button swells up and then becomes an innie belly button.
"It's good to be you," he says with a laugh, "By removing the jockstrap from you, I made your changes permanent, doggie. And now when I peel this strap of me, I'll permanently become you-the old you."
You look at the blond guy, and realize he looks just like you used to look. His cargo shorts fit him a lot better now. He snaps a leash on your collar and walks you back to your house.
It's odd. Part of your mind is calm and happy because you're with your master. Part of your mind is racing, this shrimpy guy just stole your life and turned you into his dog. Why are you following him? You answer yourself in your mind, I'm following him because he's my master, of course.
Your master leads you in silence as he looks around from his new taller perspective. The cheerleaders see him - the former you - and run over to see him. They run their hands over his chest and then the run them over you.
"You've got a new dog?" Nikki asked bouncing her boobs up and down.
"Oh, he's so cute," gushed Stacey.
