You opened the grimoire. Your eyes, trained by years of reading, scanned over the page and deciphered the key phrases for your spell. It was an easy, simple spell made to turn chicken eggs into dragon eggs. Of course, the chances of the chick actually surviving the spell and turning into a dragon were very slim. It was just a practice spell.
You began the incantation, saying the Ancient Latin words with vigor. You waved your wand in the designated patterns, watching as it carved streaks of light through the air.

And he didn't know that. Which meant that whatever he does might be good for a dragon, but most definitely won't be for you.
Then again, his hands felt really nice...
