Cat girl for Megumin, Bunny girl for Darkness.

Deciding that a black cat would suit Megumin best, given her witch theme, and given Darkness's new pet, a bunny for her, Kazuma started to write, "Megumin will become a Cat Girl, with only black fur on her ears and tail, the ears transforming from her normal ones into cat ears and migrating up her head. Said ears and tail will be erogenously sensitive to the touch, and having her tail grabbed will cause pleasure rather than pain. Her tongue will become rougher like a cat's, but not enough to irritate a cock, simply adding additional stimulation. Her voice box will also alter to allow her to purr and meow, while still retaining human speech. Her spine will also become mildly erogenously sensitive, stimulated easily from being stroked. She will instinctively purr when happy, as well as being sexually stimulated. She will gain more catlike mannerisms in this form. She will be able to change back and forth from human and cat girl at will, but find her new form more natural and prefer it, and also feel more comfortable on her hands and knees in said form than standing.

"Lalatina will similarly become a Bunny Girl, with the ears and a cotton tail, both parts also being erotically sensitive, and the fur will be white. She will also be even hornier in this form than normal. Like Megumin, she will have the ability to swap back and forth between human and Bunny Girl, but feel more natural as the Bunny Girl."

Upon him closing the book, Megumin felt strange, but pleasurable tingles along her spine, strongest at her tailbone, as well as her tongue, ears and throat. She moaned as she felt her tailbone start to expand, and fell to her hands and knees. Her ears grew more pointed and started to move to the top of her head, growing black fur. Darkness also moaned as her ears elongated and shifted upwards, and her tailbone started growing, creating a visible bump right above her ass.

The tingling in Megumin's back stopped first, followed by her tongue, and and then her throat. "Nyah!" she mewled on instinct, before blinking in surprise at the sound she let out, before she started purring as her tail grew out, black furred like her new ears, which were slightly folded under the brim of her hat.

Darkness leaned forward, looking back as a short, fluffy tail sprouted from her own tailbone and wiggled a bit. "Oh!" she cooed.

The transformations ended, but Megumin remained on all fours, feeling like it was natural. She looked up, her new tail swaying and her ears twitching. She meowed again, and beamed as Kazuma showed her a mirror.

"Nyah, I look adorable Master, thank you!" she cooed, cutely bringing up a hand to lick at it, not even questioning why she did so.

"Me too Master, I look like a sexy slut!" Darkness eagerly declared, giving him a twirl. Kazuma grinned, already planning out his fun.
