Mate. Breed. Pups.
In the end you fully embrace your canine instincts as you step outside onto the grass of the backyard, your stud tagging behind eagerly. The mutt brushes intimately against your body, you pressing back licking and nuzzling affectionately before you lower your posture and raise your haunches keeping your tail flagged as you whine and bark to your playmate; calling him. The German Shepard circles back to your furry rump taking in the arousing scent of animal pheromones your body fumes; the scent of the mutt's sexual excitement hits your leathery nose raking your claws over the grass tensing your stance, panting in anticipation.
You finally feel the dog's weight upon your ass, pushing up on your hindpaws to keep your haunches lifted. His underbelly brushes over your lowerhalf as it's forelimbs grapple your sides, his leg and pelvis buckling into your rear. You look back briefly to find the canine fully mounted above, a bizarre and taboo sight heightening your sexual euphoria as you writhe; trembling. Your animal sex perspires with your juices waiting feverishly for that primal moment that...
You yelp, focus fleeting as all you can think about now is the act; the German Shepard's erection enters your temple humping wildly. The thick canine rod caressing your sensitive flesh causes you to squirm in discomfort never experiencing real rutting like this before, yet it drives your lust to be bred. You enjoy it; being fucked like a real animal. It's not that taboo anymore since you are already becoming one, a perfect bitch for your new mate. You pant heavily as you take in the mutt's humping, another yelp escaping your voice as you feel the engorged base of his knot pushing urgently between your folds until finally...
Pop!
Your eyes light up staring blankly ahead, carnal bliss gripping your senses. Your climax nears as you feel your stud's potency dribble inside content that your about take in his seed and bare his pups. Old human thoughts start to disappear from your mind; your confused to why you have reservations to ever becoming a dog. You are a dog, a good dog; a good girl. You want your mate; you want his pups. You're happy being a dog.
Your commitment sealed you start to feel your body resuming its earlier changes, not much left now other than your frame creaking and stretching narrowing and lengthening into a feral canine body, fur continuing to thicken into a fluffy pelt as your muzzle pushes out to its fullest length and your ears fully shape into round points. The human girl that once existed is now a slightly larger than normal Husky, and this is how you always felt like it should be.
The German Shepard begins to howl ecstatically, forelimbs hugging tight, as it's finally thrusts erupts its musky canine cream inside your pink halls flowing to your womb. You shake in pleasure as your mate's release matches yours howling with him happily in a successful and rapturous breeding. Heavy pants huff as you gradually rest upon the grass, your mate clinging before removing himself and spinning around standing butt to butt. The tie keeps you bound making sure nature takes it course as his loins dribble the remainder of his canine seed.
Run. Play. Mate. Breed. Pups.
Simple instincts as a dog is all that drives you to this day, and you are content with that fact. You have little memory of the human you once were and it doesn't seem like you will be changing back anytime soon. You are a Husky; a good girl and a good bitch to your mate, and as you look back to each other panting happily with affectionate gazes you can't wait to run and play...and perhaps go again.
Some questions may be left unanswered. How was it possible you transformed into a dog? Was it by random chance or have you always bore a Therian soul of one? Where did your mate come from; did he have a human owner to return home to? Will your new life as a dog last? Until fate decides to extend this chapter's life it appears this is where your story ends...for now.
