She leaves, with Jean stuck with her wish.

Cindy decides that she feels somewhat better now, and decides to go get a soda. Upon her leaving, Jean stops her ass jiggling. She looks around at the people watching her, with a mixture of muffled laughter, or leers of perversion that makes Jean uneasy. Jean has faced leers like that before, it always seems to be the case that she ends up in control of a pervert when she's imprisoned, but luckily it usually leads to wasted wishes or Jean easily seducing them to free her. It's not exactly looked down upon to mate with humans, after all, djinn really just treat them as their personal toys, then erase their memory of it, but that doesn't mean that Jean's kind don't possess a sense of humility.

Jean reaches behind her to inspect the damage on her poor booty, not liking the jiggling mass that meets her hands. Of the rest of her body, only her hips conform to her newly inflated rear cleavage, and makes it look like she had an operation due to its lack of sagging, but by the way it ripples and shakes as she moves, it's obviously real. She never had such an expansion of her rear before, guys that conduct wishes on her generally go for her boobs first at least.

As she contemplates this, she notices a board appearing on the corner of the wall nearest the pedestal. Jean can't read it, due to being on the wrong side of the sign, but a punk-looking guy with a retro boombox reads it, mouthing it to himself. Jean read his lips and as best she can surmise, it may be a list of already made wishes. The punk smirked, and set the boombox near her transparent box, and switches it on, generating a pumping beat. Jean gasps, and proceeds to twerk to the music against her will, putting a massive amount of energy into it like she wants to do it. Then the music stops, making Jean blink in confusion and look towards the punk. He's fixing her with a sinister grin, holding the stop button, and immediately presses the play button again. Jean groans and furiously shakes her rear again, knees bent and hands behind her head. Her body starts accelerating, making Jean wonder why, until she hears that the music is speeding up. She glances back at the punk again and seeing him meddling with the controls, turning a dial that Jean assumes adjusts the speed. As he turns it down, she starts gyrating her hips slowly and erotically, like she's miming riding a guy, then he turns it the other way, sending her butt into a blur of blue bootyflesh, hands planted on the ground and booty up.

Jean's rapid shaking starts tugging her pants down, fully revealing her bare blue behind to the world as she hears laughter around her.
