As a little time passed, Langley grew very fond of Lo’ Din. There was something about him, in his pheromones, that kept her in constant need of his presence. And constantly horny. The drive to have him inside her, filling her, was in every thought of every waking moment. Until one day, when it just kind of slowed down. Her body still reacted with violent orgasms whenever he touched her, licked her, fucked her body. But something changed. She felt hungry, so hungry, and aggressive. And sad.
Lo’ Din had been gone all day with a hunting party, and she had stayed behind with another girl, Sarah, who had been left in the forest a couple weeks after Langley. The day dragged on, as it got darker, she felt agitated. She didn’t know why, he’d been out hunting countless times, and she had been fine if not a little over horny while he was out. She rested on the floor of their den by the fire. It was so pretty. All of a sudden, pain racked her body, again, and again. Her vision changed. She threw up. and her body jerked and writhed, it seemed she was going to split in two. She passed out. The next she knew she was running through the forest. The moonlight was so bright, she could easily see. Not that she needed to. She could smell Lo’ Din. How could she smell him? The thought left as soon as it arrived, as the need to find him, to have him inside her filled every sense and reaction. 
He barely had time to sense her before she was upon him, pinning him down, nipping and biting him, licking him all over. With a massive grown he flipped her, pinning her on her back, with a snarl that nearly reached her throat before he recognized her.
“My little one? Is that you? Why yes, it is you. I know those eyes anywhere. But… You’ve changed! I didn’t know that was possible!”
At his words she looked down at herself, surprised to see a lean, full-breasted, furry body. But she didn’t care, she reached her massively long, new tongue down, wrapping it around his already exposed red rocket, and guided it right to her furry cunt. Before he could gasp she was fucking him hard, slamming him into her faster and faster. They flailed back and fourth, dirt and parts of trees exploded around them. The wildest, carnal fuck she’d ever experienced. They both sang to the night in their orgasms.
As they lay there, spent in each others arms, she faded back to her human, naked form, huddling against him for warmth. He laid his hand on her belly.
“So, my little one. It seems when you’re pregnant, you can change. This is interesting indeed.”
“Wait, what? You mean, I’m.. We’re..” she stammered.
“Yes, you will give us a little one of our own.”
