The old lady directs you to the back yard and points out several of the flower beds, each overgrown with weeds. She instructs you to clear out each of the flower beds and dump the pulled weeds on the compost heap in the back corner of the yard. She then returns to the house, leaving you to it.
You work your way through each flower bed, doing as instructed, pulling the weeds, dumping them in the wheelbarrow and depositing them in the compost heap. In a few hours, you are done and return to the house, muscles aching and sweaty.
"All done dearie? That was marvelous work you did," she says.
"Oh, thanks," you reply.
"I really want to say thanks for your help, but I don't really have a lot of money at the moment," she says, "But perhaps there is something I could give you that would be infinitely more valuable to you,"
"Oh, that's okay. This is supposed to be a volunteer thing anyway," you say.
"Nonesense, you did great work and deserve a reward," she says. "You should know, I am a witch. Perhaps I could trade your work for a spell or potion?"
For a moment, your heart leaps. But you calm yourself down, thinking it's not possible.
"I get senses about people and you seem like the sort who might be into something like that. Something of the transformation sort, actually.”
"How did you..." you start. But you stop midsentence. You might as well say it since she seems to know anyway. "Well, I always had this thing...it's kind of embarassing..."
"Go on," she prods.
"Well, I've always had this fascination with werewolves. I've always wanted to be one," you say.
"Interesting..." she said. "And easy enough."
She waves her hand in front of you and utters the phrase, "In a werewolf vos verto procul mos."
For a moment, you feel really stupid. "Okay, that was really funny, but seriously..."
"You should check yourself out kid, your wish is coming true," she replies.
You quickly look at your arms, shocked to see the previously hairless arms slowly growing coarse, brown hairs and your fingernails growing out into claws.
"Oh my god, I can't believe it! Thank you, thank you, thank you!" you exclaim.
"I modified the spell so you can transform at will," she says. "Of course, you're going to change now, just to show the spell is working..."
You run into the hall and check yourself out in the ornate mirror in the wall. You find the changes coming fast and quickly pull off your clothes, finding long, coarse brown fur growing out all over your body. You find yourself convulsing and letting out moans of pleasure as your body shifts and morphs into it's new form. Your legs shift and reform into digigrade paws. Your teeth grow out into long, sharp fangs as your nails grow out into long, curving black claws. The transformation finishes with your face pushing out into a lupine snout as your ears grow pointed and move to the top of your head.
You let out your first, long and joyful howl as a newly minted werewolf.
