Pikachu's hips widened even further, and her breasts grew larger, as did her male endowment. She gained a few inches in height and almost reached Ash's chest while standing up. Her ears changed and gained a bifurcated fin-like quality while her tail extended, with the bolt-shaped portion attached to the tip of the thin tail.
The light faded, and Pikachu's fur was replaced by dark orange fur, the exception being the white belly, the brown stripes got darker, and the previously red circles on the cheeks changed to yellow. Her hands, and tail, were covered by the same brown fur, as were her feet, which grew longer and wider. In the, she changed from Pikachu to Raichu, and she was even more stacked than before.
"Did it work?" asked Raichu as she opened her eyes, and she saw Ash's surprised look. She looked down, saw her fur color, then frowned, and said, "Great, I turned into one of those jerks. *sigh* At least, it's temporary."
"Is that why you didn't like Raichu in general?" asked Ash, trying to not let his eyes wander down to his starter's voluptuous body.
"Pretty much, they think they are so much better just because they evolved. It made me want to stay as a Pikachu to never turn into one of those jerks," said Raichu, annoyed. However, her annoyance disappeared as she felt Ash hug her.
"Pikachu, you'll always be my partner, my starter, and I'm happy to have you at my side, no matter the form you choose to take," said Ash with love and care.
Raichu's heart skipped a beat, and she returned the hug, then her long tail encircled Ash. Perhaps her rejection of evolution was a bit hasty, and the stat boost would certainly prove useful in the future.
"Ok, let me change back," said Raichu, she might be more accepting of evolution, but she still preferred being a Pikachu.
Raichu closed her eyes and tried to turn back into a Pikachu. Light engulfed her body, however, instead of shrinking, her body grew plumper. When the light faded, the dark orange changed to light brown, and the brown changed to white. Her ears gained an inner spiral toward the base, and the brown outer edge along with the yellow inside switched colors.
"Did it work?" asked Raichu as she opened her eyes, which changed from black to blue.
"Not exactly, you changed from Kantonian Raichu to Alolan Raichu," interjected Dexter.
Raichu frowned and closed her eyes to try again. Light once again engulfed her body, and she started to shrink. However, she ended up smaller than originally intended, then the light faded, and her fur seemed to return to its original color, but upon closer inspection was lighter. Also, her tail became shorter, and black, which matched a black neckline that suddenly appeared, her cheek had pink circles instead of red, and the shape of her ear was more like an arrowhead instead of its long ears.
"And now?" asked Pichu, as she looked up at Ash, who seemed much taller than before and she barely reached his waist, much to her confusion. On a side note, that placed her at the perfect height to give Ash a blowjob while standing up.
"You look cute as a Pichu," said Ash as he looked at the short anthro, who was almost half of his height, as she stood before him, then he picked her up, and hugged her.
Pichu yelped at the sudden action but relaxed soon after she was pressed against Ash's larger frame, which made her feel safe and loved.
"Pichu seems to be able to switch between stages of her evolutionary tree with the regional form included," interjected Dexter, as he floated around the hugging pair.
Pichu frowned, as she was reminded that Dexter was here, and with a bit of focus, returned to being a Pikachu.
Ash let go of Pikachu, and she was back on her feet.
"Is this the only attribute you can change?" asked Ash as he looked at Pikachu, and he knew it was unlikely that Pikachu might be able to change more than one attribute, but it wouldn't hurt to be sure.
Pikachu blinked and closed her eyes to see if she could change something else about herself.
