The vampire's guide to breaking a werewolf.
I don't know why you would; those things are filthy. But I suppose there's some appeal in taming one of them. Turning a big hulking beast into a docile little puppy...It's easier than you think.
Did you know that vampires don't even have to be invited into their dens? Werewolves are more mutt than human, so they don't count as homes. Waltz in while they're sleeping. You have to be delicate, but it's easy enough to muzzle them in their sleep and get a collar around their neck. If you use a silver one, though—which I recommend; it makes it so much fun—this will likely wake them up. Of course, do this during the new moon. Obviously you're not stupid enough to capture a werewolf while it's turned.
They're still pretty weak, at this stage. But if your werewolf is still fighting you, you can take a cloth infused with wolfsbane and press it over their muzzle. It takes a few minutes, but the fumes will make them all nauseous and drowsy. Wait until they pass out. Then you can drag them home to your basement. Chain them up. Silver shackles, of course.
The werewolf may try to reason with you. They may try to talk. Don't listen to them. They'll learn quickly that they're only allowed to growl, or whine, or bark if they want anything.
If I'm being honest, training a werewolf is like training any other dog. Reward their good behavior, and punish them when they misbehave. A good spanking does wonders. Wear your leather gloves. The sensation is worse—plus, they shield you from the silver rings you'll want to wear. My werewolf still has scars from the last time I had to correct it.
And to make them more pliable, I suggest keeping them constantly high on wolfsbane for the first few weeks. They get used to the nausea pretty quickly. But it makes them weak. Makes them susceptible to your commands. And it makes them desperate. Have you ever had a werewolf look at you, pupils so dilated that their eyes look black, begging you to collar them, or fuck them, or even feed off of them? (As if you'd ever touch their blood.) It's heady.
Pathetic mutts will give you so, so much control over them, so easily. Mine even let me pierce him with a silver alloy. Just enough that he always feels that aching burn in his dick. Keeps him nice and sensitive and wet for me (I never let him top). I think I'll do his nipples next, so I can attach a chain to them and drag him around. Pretty little puppy on a delicate leash. So good for me. Stupid dog.
There you go. That's how you get your very own pet. You're welcome.
