The young man looked up, a feral smile lifting the ends of his mustache.

His lips lifted in the feral smile she knew so well.

Her lips drew back in a feral smile of triumph.

Now her lips curved, just a little, in a smile more feral than amused.

Adam didn't move, just smiled a feral smile at him that could make a person's teeth fall out.

"I was about to say the same thing to you," he replied with a feral smile.

This time was different, and his teeth flashed in a feral smile.

It was the same feral smile she had seen before.

Because her teeth threatened to grind together, she set them in a feral smile.
