Your eyes flick nervously between the changing face of your friend, and the still panting she-wolf lying on the ground behind her. It certainly looked like a good time, but could you really trust them not to eat you?
"Becky, if this is all just a story, how do I know the twist in the end isn't going to be something like you two both eating me?"
She shakes her head, and gives a chuckle which is now starting to sound disturbingly like a growl. "Jess, come on. The only twist in this kind of story is that everyone ends up having sex. And I promise that if I do wind up eating you," she says, pausing briefly to lick her lips with an impossibly long tongue, "...it will only be in a way I can guarantee you'll enjoy"
She starts to advance on you, but suddenly your eyes catch sight of something that until now had gone conveniently unnoticed. Behind the desk that the police woman was guarding is a extremely solid-looking iron door marked 'Cells'. Best of all, there's a set of keys hanging on a nail right next to it, and there's no one standing in the way. Becky doubles up as her bones start to shift and rearrange, so you figure it's now or never. As quickly as you can manage you vault over the desk, grab the keys, burst through the door and push it shut behind you. You just manage to turn the key in the lock (thankfully, the one for this door is clearly marked) before you hear someone slam viciously against it from the other side.
After a few moments of scratching noises as they scrabble at the door handle, your hear Becky's voice emerge from outside. "Aww, come on Jess! You know no one is going to read this unless it's got the big red S sitting next to the title! Unless you want to go at it by yourself of course..."
You suddenly discover a deep yearning heat coming from between your legs, and you can't resist sliding your hand down to satisfy the overwhelming urge to- no! She's changing the story again! Damnit, you've got to decide where you want to go from here before she forces an ending on you. The big thick door should give you some peace for now at least, so you can clear your head and decide.
