You groaned as you woke up one morning, you rubbed the spot where that strange canine had bitten you. You had found it harder and harder to wear clothes lately, and so you were pulling your blankets off your naked body. You had weird dreams the night before filled with wolves and other canines in the midst of mating.
You had loved the feeling of mating with a wolf bitch as your knot locked into it, you had given into your animal instincts in that dream, but you knew it was only a dream. At the same time though, the memory of it aroused you more and you looked down at your erect cock and started stroking it, the image of your girlfriend on all fours naked filling your mind as you jerked off, the fantasy you thrusting into her pussy as she let out a moan.
As you fantasized of taking your girlfriend doggy style, you didn't notice your transformation beginning. It started with your cock, which turned red and canine as it grew out into wolf proportions. fur started to grow over your body as your hands and feet turned into claws as you moaned loudly as it turned into a growl.
The fantasy was changing and shifting, you were no longer fucking your girlfriend, now you were rutting a yellow furred wolf bitch as she yelped and growled. You thrust into her once more as your knot locked the two of you together, this just made you more and more excited as your transformation accelerated, your tail bursting out of your butt as the fantasy had descended into pure animalistic mating as you rutted the bitch, preparing to fill her with your cum.
You let out a howl as you cummed hard, the last of your human sperm being let out first before ropes of canine cum spurted out. Your face pushed out into a muzzle.
You growled as you got to your new paws, the human male that used to be there was long gone as you sniffed the air. You were now a wolf in mind and body. You wanted nothing more than to fuck and transform humans, your former life was nothing but a distant memory that was long forgotten.
You could smell a human female nearing the house and your wolf cock slid out of its sheath in anticipation. You were going to take her and make her your bitch like all humans deserved to be.
