My mind paced as I slowly felt the pressing of soft fur along my chest. Ralphy lay there, spent and happy I was with him. I began to slowly rub along his body, holding him as I felt the weight of the dog's form. My own thick shaft was wallowing in the hot tunnel of his body now as it still dripped and felt so much better with him around it.
I huffed just a little, breathing the scent of his form, my mind still groggy, as the length of time spent rutting him was more than I'd spent with such focus on anything I could remember. I gripped along him, pulling him as the pup felt so soft and nice, as I gently rocked up along him, finding the sensation soothing as I felt myself stiffening once again but there was something stirring deep inside me as I let out a slow groan, feeling my shaft throb now, as something had happened between now and then, somewhere in the midst of all that rutting, it had grown far longer, nearly doubling to a foot. How could I have not noticed that during all those... my mind raced as I thought back to hours already gone. My body shuddered more as I had stuffed inside him and felt so pleased... the smallest breach behind me as my naked body revealed a tail starting to form.... as I groaned a bit... realizing the more I continued, the more I was becoming like Ralphy... and he was.... he was so good to be with....
I pulled one of my hands back, looking as I see the formations cracking and changing, my body starting to resemble four canine limbs and one very well endowed pecker as I could feel my face slowly starting to press outward.... if I could just tear myself away from Ralphy, maybe I could fix this... but.... I could just stay here, inside of him, becoming closer to him.... the thoughts ate at me, all the while, my throbbing shaft didn't want me to argue, it wanted me to obey increasingly animal like instincts.
