Make them fight each other

Now that your mind isn't wracked by shameful orgasms you can start to think of a plan. Clearly prayers won't help you now. You'll have to find another way. Unfortunately you can't reach your silver dagger or the tiny jar of dried wolf's bane you always made sure to keep within arm's reach as a kid during full moon nights.

It's strange how you seemed to know all about how to protect yourself even as a little girl. You wish you had remembered to keep all your bedtime rituals alive, even the silly ones. With your mouth full of thick werewolf cock threatening to grind its way far too deep down your throat they don't seem so silly anymore.

Werewolves are probably like wolves, they have an alpha male leader. The first one who is currently trying to bury his shaft in your stomach is probably the leader of this pack. He commanded the other two to appear after all. You could use this werewolf factoid from your childhood that suddenly popped up in your mind. All you have to do is make them fight each other for the position as alpha, and the alpha's "right" to fuck you!
