Girl

You wake up in the middle of the night, your pussy feeling like its on fire. You start to finger fuck yourself, trying to aleviate the pain, but it starts to spread all over your body.

Looking down, you watch in horror, fur is starting to grow across your body as the moonlight hits you. You finger yourself harder, more on instinct now than anything else, and your moans grow louder and louder before suddenly turning into howls.

You feel your mind slipping away, being replaced by primal urges to hunt and to fuck as you cum again and again.

Finally, you stop cumming, and you've emerged as a full werewolf, howling in glee you bound out of the house, looking for prey.
