"My humanity is NOT negotiable!" James exclaimed with a growl, tail straining against the pants trying to stiffen up behind him. "YOU turned me into this and YOU have to turn me back! ALL THE WAY back!"
"It's not that simple, James," said Kayla. "I already expected you to come back to me and let me give you this offer, but I didn't expect you to indulge your budding canine persona so voraciously along the way. You were living it up so much, I started thinking you would RATHER be a dog!"
James immediately thought back to his romp in the trash and the amount of dog piss that was still stinking back there in the apartment. He had been "living it up" alright, he thought with cringe. He looked away from her and drooped his ears in shame. She continued explaining:
"Not all the pleasures of an animal life's can just be sampled once and tossed away for good. One of the most prominent examples that comes to mind is the basal act of reproduction."
James's ears perked up at her. He gulped and couldn't quite manage to stifle a whine.
"B-but technically it was reproduction, I only--"
"Orgasmic energy leaves an inerasable imprint on your vitalic essence. I can change YOU back, but I can't change IT back," she said, looking down toward his crotch. "I'd also expect some other side effects like extra body hair, some lingering instincts, maybe even a little stub of a tail leftover."
James looked down at the front of his pants, thinking about what was still in there. 'Really?' he thought silently. 'I gave myself one doggy orgasm so I'll never have a human one again?' He wasn't sure how he felt about that. It kind of dashed his dreams of someday having kids (HUMAN kids). And yet, after finding out what his new equipment could do for him, he wasn't sure he'd want to give it up anyway.
"But I can't just be a dog man for the rest of my life!" he insisted, looking back up at Kayla. "I have friends out there and people who know me, and what are people going to think of a walking talking dog when most people don't think magic is for real? And turning only turning almost back to human isn't going to be much better--how am I ever going to satisfy another woman if I'm a dog where it counts?"
Kayla rubbed his hands along the side of James's face in what was meant to be a comforting gesture.
"Oh, James. There are people in this circus who would embrace a well-balanced creature like yourself. And even if you returned to your human life, after what I've seen, I can't imagine you'd really be unhappy, going back home with a ... souvenir or two." She smiled and let go of his face with a shrug. "And hey, if you insist on being a pure specimen of a single species, there's always the other option: the rest of your change should run its course within the hour. Who knows? You might end up enjoying the outcome: no job, no clothes, no bills. I think I'd be a cool owner if I say so myself. I always thought it would be fun to have a retriever, and you would still get to try out other forms now and then to help my magic practice. I could even make you part of my show!"
James shifted his weight from one foot to the other impatiently. This was all happening so fast! He was going to be at least part dog forever, so how much dog did he really want? His eyes darted back and forth as though scanning for some kind of cue for how to answer the witch.
