You live in a little village, in the mountains. All the people living there are nice, happy, and always kind to help. However, there's a bad thing about this village: at night, you can hear a pack of wild wolves, howling at the moon. Nobody dares to stay out of home at night, because of it. But once a year, one of the nights when the moon is full, somebody in the village disappears, with no clue of where they went, only his clothes outside his or her house, folded and with no blood or scratches.

You go to sleep today, knowing its some of those nights. This year, nobody disappeared yet, and that was the last full moon of the year. Some of the villagers were positive about this, saying that maybe this year nobody would disappear, but deep down you all knew that the following day there would be 1 less villager. You cover yourself with your sheets, as it was a cold night, and began to sleep. In the middle of the night, you start hearing the howls, but today they heard... Different. You incorporate on your bed, paying more attention to those howls. You had never experienced something like that, the howls seemed to be calling you. You knew it was way dangerous to go outside, but what if someone was already out? Maybe you could save him?
You make it out of your house, not making any noise, in order not to alert the pack. Their howls were close, so you sneaked out of the door, caring your steps. You walked a bit away from your door, and, in a blink of an eye, a lot of wolves were surrounding you, not growling, but relaxed and concentrated in you. You gasped, but something told you not to scream, as it could make them feel nervous and attack. From the dark, you saw someone walking towards you. You try to alert him, but before you say anything, the figure walked to the moon's light. It was a humanoid wolf, way bigger than the rest, and also way bigger than you. The circle of wolves opened so he could join. His eyes shone in a bright red, and they were so enchanting... You stick your sight to those red orbs, unable to look away, as he slowly walks towards you. You suddenly start feeling hotter, more and more each second you looked into his eyes. In the middle of a winter night, you can't help but start undressing, far from feeling the cold environment. A sweet scent reaches your nostrils, coming from everywhere. You look around you and see some of the wolves, with his knotted cock out of their sheath, and others without it, which you think are females. You then feel something strange, as if you had already seen those wolves before...
The alpha, or that's what should be the big humanoid wolf, has his cock out too, but he is (of course) way bigger than the others. When you are finally naked, the scent of the alpha reaches your nose, as it was way sweeter and relaxing than the rest... Yeah, so relaxing... So relaxing you start to feel weak, unable to move, to the point you fall to your knees.
The alpha is now in front of you, with his erected knotted cock pulsing before you.
Something tells you to worship it... Your last glimpse of free will says no, but you know you want to obey... You need to obey. As you start licking it, your body begins to feel even hotter, as you are growing hair on your arms, legs, body, and face. But it doesn't matter, you only have to worry about pleasing Alpha. You start sucking on it, little moans coming from his muzzle when you see your face is also changing, as a muzzle is slowly forming. But you think its better to please alpha, as that way you can take more of his shaft inside you. That last glimpse of free will? It doesn't exist now. His cock twitches inside your new muzzle, before releasing a huge load of his alpha seed inside you, completely making you his new loyal wolf. You go on all fours to end your transformation, leaving your clothes behind, and you get ready for your new life as a subby wolf for the Alpha. Once a year, you all come to the village again, for Alpha to make another sub wolf. You love your new life, with your new family, and enjoy pleasuring Alpha every time he wants to.
