Krissi sat in silence as she heard Dustine clop around upstairs gathering items to make the perfect bath for her lover. A hand flew to her head. She had just transformed Dustine to her whims. She'd deleted her entire personality, memories and all. Something like fear, and something like fire, flashed through her. There was a sort of power that came with having that much control over another person, and it excited her. She wanted to go further.
With a thought, she willed Dustine to not be affected by any further transformations; she would not feel dizzy nor sick, she would not become tired, and most importantly, she would not notice that anything had changed. Her second change was a bit different. She allowed Dustine entrance into her mind. Dustine would now be able to sense her desires and commands telepathically, and surely even pick up on her unconscious desires, making Dustine not just a great lover, but literally perfect, able to give her whatever she wanted, before she even knew it. Krissi focused on this bond between them, and called Dustine back downstairs.
Within moments, the sound of hooves thundered down the stairs. "My love, you called me?"
Krissi grinned. It had actually worked! Now, to try her other change. More beautiful, Krissi urged. More magical. Dustine, only reading her want to enjoy and soak in her body, posed as a new set of changes rippled through her.
In her silky white mane, streaks of pastel pink and blue began to appear, echoed similarly in her tail. Her legs lengthened, ass growing cutely heart-shaped as her hips widened, and her waist sucked in, accentuating her 6-pack. Those abs soon became an 8-pack as her whole body grew stronger and taller, to an incredible 7-feet tall. Even with her enlarged muscle, they didn't stand out or make her less feminine - in fact, she only seemed to grow more alluring with each passing moment. Her breasts swelled up beyond the size of melons, firm, plump yet effortlessly soft and inviting for Krissi to sink her hands into. Dustine's gorgeous, chiseled face took on a new light as her eyes became deep, swirling pools of violet that glowed in the dimly lit basement. Finally, a glowing horn grew from her forehead, made of two twisting threads of blue and pink, making Dustine the perfect unicorn girl.
"You do enjoy the sight of my body," Dustine teased, not unkindly. She hadn't even been winded by the transformation. "Perhaps I will have to let you explore it later."
"Oh, yes, please," Krissi breathed, as the unicorn took her into her arms, squashing her face between the two enormous breasts. Grinning, she skimmed Krissi's mind and pushed the horny girl deeper into her cleavage, until she could lick the sweat off her skin. Her second pair of arms (that, while she hadn't noticed the appearance of, had come about from Krissi's depraved mind) came around to grab the smaller human's ass. With a playful spank, Dustine pulled Krissi off her.
"Ah-ah! Let me draw you a bath, darling, and then we can have a much more intimate examination of one another," she purred. She left Krissi with a kiss as she sashayed up the stairs once more.
