A shortstack?

As the smoke cleared, what now stood there was a young woman, seemingly about the young man's age. She was very short. Probably under five feet tall! Despite this short height, her figure was plump. Thick, luscious thighs. A large, ample ass. Wide, childbearing hips. The slightest of paunches to her tummy. Her breasts were downright disproportionately large, each probably the size of large watermelons, and they just looked larger on her small frame and short height. Her skin was healthily pale, her eyes a golden amber, while her hair was a vanilla white color, straight and reaching the small of her back.

Despite clearly looking human now, she still had evident indications of demonic taint. A long, prehensile, arrowed tail sprouted from her tailbone, swaying back and forth like a curious cat. Small black horns curved upward from between the folds of her hair. Bat-like wings adorned her back, folded against her as if to store them when not in use. Her ears were long and pointed, sticking out horizontally from behind the bangs that framed her face. Pinkish markings decorated seemingly random parts of her skin, which he could only describe as runes.

All this came together for a girl who would definitely stand out. But it all paled in how conspicuous it made her to the fact that... she was completely naked.

Her pussy was clearly visible, notably bald with not a hint of pubic hair. Hell, her entire body was void of body hair. Her nipples were a rosy pink, slightly erected and a bit on the small side compared to the expanse of breastflesh they tipped.

All in all, she was... well, if he was being honest with himself, really cute. Like something out of an anime. Smol, petite, juicily plump, curvy, ridiculously buxom, lap-sized... And the most dangerous demon in all of Hell. Though he couldn't help questioning why she... wait, he? They? Why the Demon King had chosen this particular form. Why so short? Why so buxom? Why so curvy? It was almost the exact opposite of the Demon King's spiney, tall, imposing form of black demonic hellfire from before. Was the Demon King okay being a woman now? Wait, was the Demon King even male before? Was this form even biologically functional and oh no he might just go cross-eyed from all this overthinking.

"Is this form more acceptable to you... darling?"

She smiled, wrapping her arms under her bust and hefting them up as if to present them to him. Despite her forward and flirtatious presenting, she bit her lip, her tail snaking between her legs like a scared dog. Was she that nervous about his approval? Her voice, previously deep, booming, and omnipresent, was more normal now. Soft, beautiful, melodic, and even a bit on the tiny side. This time it clearly came from her mouth, too! Her... full-lipped... mouth.

Wow, this was a lot to process.
