Parker did not see a way to get away from the bear, so he remained still. She seemed curious instead of dangerous... why did he think the former boy had become a female? But his nose reported the sex of the animal, and he no longer felt afraid. Attracted, though. That was ridiculous. Besides being way too young, this was now a bear. But she smelled so good.
Puck grinned as he saw the child's clothing crumble away, and the dark sweep of fur across his back. Although Parker would remain five, he was becoming a bear. Which would be mature at age five. It took a bit longer for Parker to realize his body was getting larger. The female bear was getting more interested, and Parker watched with a mix of horror and amazement as he gained muscle and mass.
Given that the fae could do anything they wanted with him, Parker decided to go with this new male drive. Even before he was a bear, he snuffled back and rubbed against the female, then licked her. Fully a bear in mind and body, the new female responded, and Parker knew what to do. He slid over the female's back and mounted her with a powerful thrust. Puck flew up to watch the animals mate, adding both pleasure and longevity to the act. Parker was fully changed to a male bear long before he finally jetted into the female. The two animals shuffled out, and though Parker still remembered his past life and even that of being the boy, he found that this new existence as a bear was satisfying enough. Maybe human memories would fade, but they were already unimportant. Puck made sure the bears exited the area, and also tweaked both so they would mate several more times during the night.
