Micah's penis felt hard and oddly large, and he looked down to see it had become very different. Pointed, slick, and pink, an erection jutted out from his crotch, getting longer and thicker even as a band of flesh formed around the base and began to draw the organ closer to his belly. Micah recognized what looked to be a dog's penis, as well as the rounded shapes swelling out behind it. He was like a boy dog. No, a boy wolf! And... a strong scent from the other wolf drew his attention to a second opening under wolf's anus, one that was increasingly inviting. He was confused, not so much be the situation, but in finding that he knew what to do, as if he had mounted a female many times before.
Leaning over the wolf's rump, he started thrusting, taking several tries before the hard shaft found the bitch's opening. She backed up as he fell over her with a gasp, driving deep. Instincts, new and yet familiar, drove him deeper and he slid over her back to grip her sides. He was thrusting rapidly, the sensations far stronger than they had been when the wolf licked him. Micah could feel his body shifting, his arms getting longer and thinner, hands closing into furry paws. A new swelling began to form at the base of his cock, and his outward tug was stopped as he knotted inside the female. Micah's whole body throbbed, and he tried to cry out. What emerged was a strangled whine than turned into a surprised yip. His face was pushing out, forming a long muzzle. He should have been terrified, but there was such a sense of need, of fulfilment, as if this was what he had been born to do.
Locked in the female, Michah shuddered in release, now fully transformed physically. It didn't feel strange being an animal - instead, the idea of being a pale, hairless creature that walked on two legs was becoming hard to imagine. His childhood was altering, memories of home and parents fading as instincts and knowledge of living as a wolf for years filled his mind. Even the name Micah twisted into a smell that was his identity. Confusion eased as the male wolf waited for his knot to ease, then pulled out of the female and pressed against, both panting from the experience. He licked the female's sex and shook himself, instinctively moving deeper into the woods, away from the humans. There were other wolves here, a pack that he now knew and had memories of growing up with.
