I knocked on her door, moments after she let herself in, quickly making a wish that I would soon reveal to her. She opened it, looking a bit confused about my sudden appearance at her door.
"How did you find out where I lived?" she asked, trying to hid a twinge of obvious uncomfortability. I could tell that she really preferred that her students not know where she lived.
"I know a lot of things lately, Miss Parks," I replied smoothly. "Like I know what you are."
"What are you talking about?" she asked me, "don't make me call the police."
"I wish you wouldn't," I told her, smiling.
"Alright," she replied, acting as though she'd never really meant to.
"I wish you'd invite me inside, " I said, walking through the doorway, already knowing what her answer would be. As I expected, she shut the door behind me.
"So," she said, still maintaining her teacher's tone of voice, "What do you mean that 'you know what I am'?"
"Exactly what I said," I told her smugly.
"And what am I then?"
The words escaped my lips with a smile, "You're a werewolf, but you only transform when you taste semen." I'd already silently made the wish, but I felt it would be somehow more dramatic to reveal that I knew. It almost had a b-movie quality to it. That was the best part of this power, I realized: I was like a sick movie director, and all the world was potentially in my movie!
Her eyes widened when I said it; she had thought her secret safe. (Though it hadn't actually BEEN her secret until I'd wished it.) "I...I..didn't think anyone knew...I've been careful...how, how did you know?"
"That's not important now. But you know what? That sort of thing turns me on, Miss Parks. I wish you'd suck me off."
I was bulging already, and she saw it. In a flash, she was on her knees, tugging at my fly. She tongued me with expert technique; she was hungry for my load. I happily obliged, loosing it in her mouth with a freakish quickness. Damn, she was good at head!
She pulled back, swallowing it, licking a bit that oozed from one corner of her mouth. "Yess...yess!.."she whispered in a low tone," I can already feel it starting..." She smiled up at me, her brown eyes changing to gold. She gave me a wide smile, her teeth already sharpening into fangs. She tore away her blouse, revealing dark brown fur blossoming between her two original breasts, as two more sets began to grow lower on her torso.
Her body trembled as it grew thicker with muscle. The rest of her blouse fell away, shredded when she arched her back, tearing it apart as her frame grew wider. A tail began to blossom from her ass, pushing her skirt up. I noticed with a smile that her pussy was still quite human, although quite furry, just as I had wished. I also noticed that her new breasts were just as large as her original pair, again, just as I had wished. Her face finished stretching out into a muzzle, and her skull receded slightly, and Miss Parks let out a howl of satisfaction.
Having tested out my powers a bit, I felt quite confident. There literally was no limit to what I could do! I realized I could move on to phase two of my plan. "I wish you'd change back to your human form," I told her, "we have work to do."
