After concluding their sexual congress, Mary and his new girlfriend indulged in the kind of play common to canines everywhere, even hunting together as he drove a rabbit into her waiting jaws. But there was one thing Mary was curious about. "You said most werebeasts change genders. Did you?"
"Yes" she answered. "I believe you are a child of the vials, but my sister's and my story is different. When my father died, our sister tricked me and my brother into wearing these necklaces. We can't take them off, and while we have them on we are cursed to roam the world as she-wolves. We have all the normal desires of she-wolves, for hot blood gushing into our mouths, for sex with male wolves, to bear and raise litters. To tell the truth, I can barely remember what it is like to be a human male."
"How long has this been going on?" Mary asked.
"Hard to keep track of time as an animal" the she-wolf answered. "Possibly around two centuries. Our sister is long dead, so we can't even dream of vengeance. The only thing that can lift the curse is the touch of a unicorn's horn, and unicorns aren't even real."
Just then Mary caught the scent of another she-wolf. A slightly smaller wolf bounded up to the two. "Sister, I hope you weren't planning to keep this one for yourself! He looks nice!" Mary noticed the new she-wolf gazing at him with undisguised lust, and felt himself respond in kind.
"No, sister," laughed the first she-wolf "This one is too good to keep to myself!"
