Jeff felt her belly expand quickly. Those eggs sure were getting big, and fast too! Although it almost felt like it was just one BIG egg. Jeff nuzzled her snakey form against the bulging belly of her incubator half. It didn't matter what was inside of her, all that mattered was that it was hers. With the way it was growing though, she wasn't sure if she would be able to carry her new weight. Just then, there was an odd feeling in her limbs, and they began to swell with energy. The power radiated out from her core, first pushing into her muscles, making them expand to the size of tree trunks. Her fingers and toes then reconfigured themselves rapidly, melding with eachother and cracking as the joints reformed. They soon shared the same appearance, 3 digits on each, with perfect radial symmetry. With a *SHINK*, the nails on her digits shot out to sharpened points. With her new form, it seemed the weight in her belly would not be difficult to hold up at all.
The power continued to pulse out from her center though, and it worked her way into her phallic snakey form. Which extended longer and stronger. Jeff moaned softly as tough muscle was pumped into her cylindrical figure. She even felt her pussy join in. It expanded out far beyond its original size and drooled heavily with juices. It seemed that her birth wasn't going to be too painful. With that thought-- Jeff began to feel her pregnancy complete, the huge mass inside of her moved closer to its goal. Jeff twisted her head towards its exit, groaning in pleasure as the growth rubbed tightly against her walls. What was only a few minutes felt like hours to her as the singular egg made its way out of her body.
Jeff panted heavily as she looked over her creation in pride. It hadn't taken her long to create it and yet it was so beautiful. She coiled around it tightly but gently with her now much longer length. She wouldn't want to hurt her precious egg, or whatever was inside of it either.
