Trickster was taking a nice stroll through the forest on the outskirts of town. It was a quaint little piece of land where people could come and walk through, taking in the nice nature of it all. After such a busy week, the bunny was happy to enjoy some time away for everything and relax by the lake.

As Trickster walked, he noticed a strange shining object resting on the bank of the lake. Curious, the bunny walked up to it, bending down and picking it up. He brought it closer to his face to examine it closely. It was ruby in color, and on the inside of it there was a mixture of yellow and orange inside of it that resembled a fire.

"Why does this look so familiar...?" Trickster asked with a raise eyebrow. His confusion would change into panic, when he noticed that the stone was melting! It wasn't falling off of his body however, it was more like it was merging into it instead!

"W-what the heck!?" Trickster tried to toss the stone aside, however, that only caused it to spread all over his body. It didn't take long for the stone to fully become one with the bunny, and this caused a burning sensation to form within him, initiating a transformation for Trickster.

The bunny's ears started to shrink down tremendously, sticking upward as they started to take on a triangular shape. They were still long, but only about a quarter of their original length. Trickster's muzzle became longer, while taking on a thinner shape as well. His black nose flipped into a black color, the whiskers on his muzzle leaving him entirely. His various shades of brown fur on his head would shift into one solid color, that being beige. The only exception to this would be the insides of his ears, of which changed into white fur instead.

Trickster's chocolate brown hair lighten in shade, taking on a beige color  as it began to trickle all the way down to the center of his back, becoming much fuller in the process. More of his facial features altered, with his eyes becoming larger and turning from purple to red. Trickster's eyelashes grew becoming more noticeable while his eyelashes did a bit of the opposite, taking on a thinner look to give Trickster a feminine face.

The changing bunny's shoulders cracked downward, losing their broadness as they became more narrow. To keep up with his changing proportions, Trickster's arms became thinner as they slenderized, hands following in suit as they shrank and his fingers both thinned and elongated to gave them a dainty appearance. After that, the multi-colored brown fur became beige like his head, that same fur continuing to spread until it reached his feet, all of his fur changed to be one solid color.

Trickster's figure continued to change, with his sides pushing in to make his waist appear more narrow. His back caved inward, forming an incline into his back. While parts of his figure curved in, other parts curved out. Trickster's hips expanded, growing into a wide set of childbearing hips. Similarly, his rear began to swell, becoming much more pert and pronounced. The curves continued down Trickster's legs, with his thighs and calves both enlarging, the inclines between those deeper to make them shapely. With that, the bunny's figure was undeniably feminine.

His feet shrank down in size, even losing a digit in the process. The last part of his transformation in species changed with his tail. It burst out in size, becoming incredibly larger, now almost the size of his body itself. Once it reached that point, it began to multiply, leaving Trickster with nine different tails resting behind him. They were primarily beige like the rest of his fur, with the only exception being the tip of which was orange instead.

And with the species changes coming to a close, the last bit of his physical changes arrived. Growing out from his chest, two mounds of flesh started to emerge. They continued to grow into two soft, spherical mounds until he possessed a sizeable pair of breasts. Between his legs, Trickster's manhood receded into nothingness, completing his transformation into a Ninetales woman.

It didn't quite end there, however. Trickster was starting to change mentally as well. Thoughts and memories of ever being a bunny man were rapidly being replaced by those of growing up as a little Vulpix girl before becoming a Ninetales after puberty. Everything from her first bra, first kiss, her time in high school on the girls soccer team, it was all there. He wasn't Trickster anymore, but Dianna, the sporty Ninetales girl!

With a new mind in tow, her outfit changed to fit her new form. Trickster, now Dianna would have her undershirt shrink upward, forming into two cups to support her new breasts, the sleeves becoming straps as the back melted into another strap to help support her bosom. Dianna's boxers took on a similar change, changing into a pair of panties. Her shorts tightened around her legs, riding up her legs a bit up to her hips. The purple carrot hoodie would have the hood and front pockets leave, becoming thinner as it became a simple shirt. The sleeves rode up to her shoulders, leaving only thin straps left behind. The cut of it dipped down a bit as the former hoodie was now a tank top, completing the transformation entirely.

Dianna shook her head. "Man, I don't think I got enough sleep last night, got a head rush there!" She started to stretch out with a wide smile on her face. "But, nothing beats a solid Saturday jog! I heard that a new soccer league is starting up soon so I have to make sure I'm in tip top shape!" she giggled as she reached into her pocket and pulled out her phone.

"A selfie wouldn't hurt!" she smiled, snapping a picture of herself in front of the glistening lake. "Now that's a cute one! I gotta bring Tammy out on one of my jogs one of these days! That Sylveon never gets her exercise in! But that's to worry about later, let's finish this jog strong!" And with that, the new Ninetales jogged off, unknowingly starting an entirely new chapter of life!
