You then wrap your somewhat shaggy fur-covered paw-like hands around her hips as you get ready to plug into her. You feel another moment of hesitation. You know that in the back of your cloudy mind that this may be your last chance to turn back. But your hesitation soon passes as your newfound canine instincts begin to really kick and help guide you on your way to being a large, shaggy sheepdog. Like you have done it many times before, you slide your throbbing cock into her till it has practically disappeared up to your knot.
You growl loudly and pleasurably as her tight cunt swallows up your cock, and firmly pushes what little doubt you had for mating with Abby. Firmly you wrap your shaggy forequarters around her bear-like hips as you transfer your weight to her rump and your toes. You begin to pump your canine cock in and out, pushing it in even deeper and faster than you ever could as a human. Your knot finally slides into her body, and your thrusts take on a short and rapid motion accordingly. Quickly, you feel yourself cumming into Abby while growling and panting with pleasure at what you are doing to satisfy both of your needs.
Time passes for you and Abby. By the time you come back to a semblance of your former human mental state, you find yourself standing rear to rear with Abby, your knot still firmly stuck in her. You look at yourself and without much regret, you see that you have transformed completely into a large, male Old English Sheepdog covered in shaggy white and dark gray fur. And what you see, smell and hear about yourself feels so completely natural that you wonder why you were so reluctant to fully change yourself over into a sheepdog in the first place. Oddly you feel great being a large, shaggy dog. You start panting contentedly as you allow yourself to roll with your new canine instincts.
Another few minutes pass you by when...
