The Predator Streak

You calm yourself from the excitement of your first feeding, and allow your supernaturally sensitive hearing to pick up the distant sound of rutting... and is that snarling? You tread carefully, worried as to what is occuring, until you find your newly made spawn inside an apartment - past the shattered remains of a front door, desperately fucking the still-erect penis of an obviously-ydying human, his blood escaping rapidly from wounds to his neck and chest.
The expression on the face of your creation is shocking, even to the eyes of evil. The creature that was once Dani has no streak of humanity left, no sense of beauty or of cruelty, just an animalistic need to fuck and be fucked. You smile a crooked, fanged smile; you realise that you may have inadvertently created the very embodiment of the Lilith Strain.

You quickly realise that you will need to restrain your offspring. This will require a plan, and soon - the expiring male will not maintain his erection much longer.
