Some enhancements

Her enthusiastic reaction to the second, much messier blowjob sent a fresh surge of power through you. You were no longer just a guy with a magical ability; you felt like a creator, a sculptor, and she was your masterpiece. It was time to elevate her even further. You changed her mind, now it was her body turn.

"Maisie," you said, your voice firm and commanding, "Strip completely."

She didn’t hesitate. You even grew to regret how straightforward your order was. Instead of doing something sexy and pleasing your senses, she somehow got rid of all her clothes in what seemed like seconds. Anyway, for the first time ever, you could see her nude body. Her delicious breasts, her slim waist, her toned thighs. You completely forgot that doing it all in the car park wasn't the best idea and just ogled the naked skin of your childhood friend.

She was good, real good, but your darker side whispered that every asset can be improved.

"Maisie," you said, "Your breasts will become one size larger, rounder, closer to each other." As your words hung in the air, her breasts began to swell visibly, growing heavier and fuller before your very eyes. They lifted higher on her chest, settling into a perfect pair of tear-drop shaped globes with barely an inch separating them. Her nipples darkened slightly, stiffening into prominent peaks that practically begged to be licked and sucked.

Her reaction was instantaneous. A low moan escaped her wet lips as she cupped her enhanced tits, squeezing them experimentally. "Ohh," she sighed contentedly, "They feel amazing. Heavy and sensitive. Not that disjointed feeling I sometimes had. Thank you."

Next, your gaze traveled lower. Her stomach was already relatively flat, but you craved perfection. "Maisie, your abdominal muscles will develop more defined lines, giving you a subtle six-pack that leads downwards towards your pelvis. Your skin here will become taut and smooth." Watching it happen was mesmerizing: muscles rippling beneath her skin as they formed and solidified, creating a gorgeous topography beneath her navel.

She reacted with another audible gasp and giggle, making her new stomach tremble in a cute way

Then you moved onto her hips and buttocks. "Maisie, your hips will broaden slightly, becoming more curvaceous. At the same time, your ass will lift and fill out, gaining volume and developing firmer muscle tone underneath the fat layer." You watched transfixed as her silhouette changed, becoming exaggeratedly feminine.

Finally, your attention returned to her face. She had a nice face, familiar and pretty, but you wanted to tweak it just a little to match the rest of her newfound goddess form. "Maisie, your irises will permanently shift to a striking emerald green. Additionally, your upper lip will gain a bit more fullness, and both lips combined will become noticeably softer, primed for kissing or wrapping around a cock." The transformation happened quickly, her eyes lighting up into brilliant green jewels, her lips puffing up slightly, looking impossibly inviting.

She blinked her new stunning green eyes and smiled softly, touching her sensuous lips with her fingertips. "Wow," she breathed, admiring her own reflection in the rearview mirror. "I look hot with such a bright green color. Thank you!"

For a moment, you simply drank in the sight of her, this superhuman version of your friend, created specifically for your pleasure. But your appetite for improvement wasn't satiated, remembering recent blowjobs.

"Maisie, I want you to be able to take all of me in your sluty mouth, all the way to the base, without any trouble. Your throat muscles will strengthen, and your gag reflex will disappear completely.

She gasped slightly at the command, a look of intense concentration crossing her beautiful new face for just a second. You could almost imagine feeling the internal rearrangement happening within her neck. When she opened her eyes, they were hooded with lust. "Let me show you what I can do now," she murmured, leaning across the seat once more, her enhanced naked breasts brushing against your leg.

Her intention was clear - give you a blowjob number three. Without any direct command from you, only on the basis of how you changed her personality. It didn't sound like a bad idea but there were more of her to enjoy. And, a single thought broke through all the aroused delight in your mind - they were still in a public place, increasing the risk of something unpleasant happening.
