As her pelvic fins sway back and forth rhythmically, you place one hand on her belly and her body immediately begins to relax. Her vent is swollen; her desire is clear, but is it really appropriate to do something like this? It isn't something you'd normally do, but you can't really stand by while she's suffering like this, so you gently rub your finger along the edge of her vent. In an instant, you can feel a change in Belle's demeanor; her tail thrashes wildly as her breathing grows faster, her mouth gaping open as she stiffens up.
It's almost as if she was invigorated with a burst of energy, and she tries pushing you deeper inside her. Whatever it was that was bothering her, this is clearly working, so you comply; sliding your hand up her body while one finger explores her depths. The deeper you go, the stiffer she gets, until it looks like her scales are starting to glow; it quickly becomes blinding bright, too. As light erupts from her scales, you can feel her body start to shift and change. With your finger still lodged in her vent, you can feel her transformation occurring in real time, her muscular walls wrapping around your digit, shifting and changing along with her. You can't see a thing, the beams of golden light reflecting off the surface of the water are obscuring everything but her silhouette.
It doesn't take long for you to realize what's happening; she's evolving! That must have been what was bothering her, this whole time; she just needed one last push! As the evolution takes over, her body starts elongating and becoming more serpentine, her fins lengthening, turning into a tail as it wraps around your torso. The change goes on until all of a sudden, the light fades and she stops growing; as you open your eyes you can see her, Belle has evolved into a Milotic.
