Vampire's Pet
I soon found myself to begin shaking as well, grip tightening on the pillow.
Every pet knows that this time would come for them, but even that can't compare for when it actually happens.
Even though I knew that Nico was trying to fight it, he and I both knew that he couldn't fight it forever.
Those kinds of predatory instincts run through him like his own blood, only allowing him to fight it for so long until it consumes him. He knew that once it did, he wouldn't have much control over what would happen next.
It was the instincts that kept vampires alive no matter what once their species first began to grow.
