Ty now saw the creatures who had just conceived him were a pair of wolves, who now lay down to sleep, the male's knot still inside the female. Ty's heart raced at the prospect. He had always thought werewolves were so cool, the idea of being an actual wolf was so awesome to him!
And as his fertilized egg form developed inside the female wolf, Ty saw himself in his mind's eye and watched as the genetics of the wolves made his form lupine. He developed large sharp fangs, a pointed snout and ears, strong legs with clawed paws, a sensitive nose and eyes for hunting, a tail that helped him balance and marked him out as an animal, thick dark fur to warm his body.
He slowly realized something that took him by surprise. He somehow felt more in common with the female wolf than the male. But he was a boy, wasn't he? Oh... Ty understood a split second later. The sperm that had fertilized him had had an X chromosome instead of a Y.
The onset of this change seemed only more enticing to Ty. He had already wished his body away and wished his humanity away, now he had unintentionally wished his gender away. Being this wolf would be nothing like anything Ty had ever felt before.
As the development of Ty's sex came, he turned into she. His penis receded away until only the head remained, which became her clitoral nub, and his testicles moved up inside him to form her ovaries, while his scrotum flattened and then peeled open into her vagina. Down her chest and stomach, rows of nipples formed, tiny sensitive teats for her cubs to suckle on.
With these changes to her sex came changes to her sexuality. Ty had never thought of guys sexually before, but as a female wolf, the idea of a thick male cock to knot her was deeply enticing. She wanted badly to be fucked by a male, mated by his seed and to bear his cubs.
Before she knew it, she had been birthed by the female wolf that had carried her, and looked around at the world in a haze, the sexual desires she'd had suddenly feeling very awkward in her immature state.
