Filled by a Werewolf in Captivity

Arya wakes from her slumber when a stranger is thrown into her prison cell. "A companion for you, Kitten," the man says with a smile that does not reach his face. She has been in here for a few weeks. She was supposed to be a way for them to make a quick buck. Cat Shifters fetch a lot of money in the black market. 

Except they vastly underestimated the amount of attention her disappearance would garner. There is a nationwide hunt for her, and her captors aren't able to find any bidders willing to take that risk. 

At first, she thinks the man thrown into the room is just another Cat Shifter, a prisoner like herself. She is quickly proven wrong when he stirs and bares sharp fangs at her. He's a Werewolf and judging from his sheer size, an Alpha.

She is in so much trouble.
