You decide that the Outback Section of the zoo would be a good place to watch your buddies change and screw animals. It's kind of far away, but if your classmates don't make it then there's at least other people to play with. You think back to the wording of your spell and how to change it to include girls "let's see, I said every boy in my class,when each sees a different animal.." you pause as you notice a mentally handicapped kid walk by with a companion animal.
You immediately recognize it as a female labrador, and become transfixed with how it's black tail bobs back and forth as it walks. Your hand rubs over the front of your crotch as you feel it heat up and tighten.
You realize you've just become the victim of your own spell, but an instinctive push from inside your pants tells you that you don't want to take back that spell just yet. "I wish that as we fuck that instead we'll be turned into anthropomorphic versions of eachother". The zoo is practically being evacuated by the security and you easily rush the kid and take the dog. The kid continues not even noticing the dog gone as you rush yourselves into a restroom.
The dog seems interested in you, or so you think as you take off her collar and harness. Her tag reads Sophie, "okay Sophie, let's go" you say as you take off your shirt, shoes, and pants revealing a crotch covered in black dog hair with a wet red tip sticking out of a respectable sheath. You sigh with delight as your cock tastes the open air and your scrotum freely falls a couple inches.
You cock instinctively marks the floor of the bathroom, prompting Sophie to come lick your crotch. "Good dog", you get on your hands and knees and kiss her, she licks you back but only playfully. "I wish you were in your worst heat ever", you say. Sophie's demeanor suddenly changes as she salivates all over you face and tries crawling under you to moisten your member. She's as ready as she's ever going to be, and you try to hold her head and neck as well as possible while manuevering around to her back. Sophie understands and shifts her weight to her hind paws.
Wanting to avoid her anus you look at your own dick to guide it into hers. Your surprised to see it now poking out of your sheath like a pointed, wet, summer sausage. You grab yourself at the end and lose your grip, "too slippery to control", you then just make a loop with your thumb and pinky and use your other fingers to find her sex. You're met with another wetness like you felt before, "you're huge, this won't be any trouble at all". With that you plunge into her depths and lean back and crouch to aid you in thrusting.
You can't believe how hot she is on the inside while grabbing her haunches and thrusting in. Then the changes start, silky black hair covers your hole body causing you to pant with heat. You're aware of a tail twitching back and forth from your butt as well as the bitch's waving in your face. Your feat grow pads and claws while your legs crack, making your thrusts more fluid. Sophie's legs grow too, causing her sex to rise up to your preferred level. Your face pushes out making room for your growing tongue and teeth. You suddenly become aware of sounds and smells now inside your range of perception, but the smell of sophie and the sounds of your mating are all that concern you.
Your fingernails have turned into claws and rudimentary pads are on you fingers, toes, and palms. You can still grab sophie's waist firmly, and push even harder into her, sending a bulge at the base of your penis firmly into her. You both howl with delight and continue thrusting together, your cock now firmly immobile in the confines of your bitch's vagina.
You soon tire and collapse on her back, she rolls over, depositing you both firmly on the restroom floor. You lick the back of Sophie's neck, and move your arms to hug around her waist. "I want you to be my mate Sophie", Sophie turns her head back and gives your muzzle a quick lick "I,,,what am I". Sophie and I were both anthro lab dogs, are bodies laid together perfectly. "I made you Sophie, you were a stupid pet, but we changed each other." Sophie started whimpering, she wasn't a lab dog anymore so I didn't have the urge to fuck her, but I also wasn't disgusted with having her attached to my cock. "I wish to undo my wishes to uncontrollably urge people to fuck animals", you say out loud.
"You can make such things happen?"
"Yes Sophie, I have power to do anything, but right now let's just get up and go to the zoo's main office." With that Sophie rolls onto her belly, and pushing your paws on her lower back and stomach take yourself out as painlessly as possible.
You stand balanced on the ends of your former feet and stare into a mirror. "Please don't turn either of us back" whines Sophie, "I don't want to go back to being a stupid dog, I want to be with you, not people", Sophie is on her paws begging now. "Don't worry, I'll take you with me and you'll be like this forever, I might have to change back but I'll always be there to service your needs, now get up and let's walk".
Walking on two legs wasn't as natural as coupling, but Sophie and I managed to do a good job till we got to the main office.
"Who are you two?" said a female zookeeper.
"I'm Danny, this is a dog I'm taking home."
"Fine that dog isn't one of our animals and the owners probably won't want it now anyway, now go sit in the lobby and wait with the others."
I guided sophie to the lobby where we both crouched on our haunches and sat on the floor. The zoo had been deserted on our walk, and it looked like all the boys in my class had fucked an animal. Dustin was cowering in a chair staring at his tail. John had the head of a wolf but must've been himself because inspite of the heat he was covering himself with a blanket. There were a deer and an some antelope, all different species of course.
A zookeeper was leading in someone covered in porcupine quills, "is this everyone?" I asked. "No, there's about five of you little perverts in the large animal barn, and another two of you in bathtubs. What you kids did is beyond me, but four of you are still unaccounted for." I wondered if they'd completely turned into animals, though I definetly which animals they were not.
Sophie was still a bit scared of being intellignet of her surroundings, so I stayed by her in the lobby without bothering to look for everyone else. "I'm sure the girls are all bussed away by now".
"No they're not, four of them are coming in now." yipped Sophie.
With that, in walked four pairs of anthro red foxes, jaguars, kangaroos, and musk oxen, the males all had vestiges of clothing, but the females were naked except for their fur.
"Wow, I guess when I wished us to change into the same form I said it in a way that affected everyone who mated after us".
The zoo people seemed a bit pissed off, "dain it, not only do these kids screw our animals but now four of them 'want' to leave the zoo and be with their studs."
I licked Sophie's nose as cars started to pull up, maybe it would be the zoo to suddenly take in a bunch of new animals.
