"Jupiter. I want to become Jupiter." you tell her.
"Good choice, the biggest planet in the solar system. Now, please formulate your wish in the exact way you'd like it to be." she says. You meditate for some minutes, thinking of the best way possible, and finally explain:
"Genie, I wish that I become the planet Jupiter, and that you do it by freezing time, then teleporting us to the space, make the original Jupiter dissapear forever, but keeping the moons in place, put me in the location of it's former center, and transform me into the giant. As for everything after the transformation, I wish that I could see and feel everything happening to my surface. I also wish that I never go crazy from becoming such a thing, that my moons act like they always did, that I become so inmortal that no dangers of the space would ever harm me, or that I unstabilize or explode or something like that."
"Very well, Master. I'll freeze time now." she says, before snapping her fingers. You look through your window, and see that time has really stopped.
"Now... prepare to see the space." she tells you. Another snap happens, and you feel yourself dissapearing and reappearing in another place.
You're now in outer space. Everything is so dark... and HUGE! You see blackness extending to the infinite, countless stars shining, and all these planets... you see all the planets from the solar system, even the Earth, your former home, which looks so small... and just in front of you, the gas giant, Jupiter. You feel small as an atom in comparision to this titanic maroon sphere, and shudder from knowing that you're going to look like that soon.
Just then, you realize you're alive because you are in some kind of bubble floating in the darkness, next to your blue genie, who says "Truly a majestic view, right? Time is still frozen, let's go to the next step." After she pronounces these words, she snaps her fingers again.
It felt like popping a giant balloon. A brief moment after, Jupiter is gone, leaving absolutely no traces of it's existance. You ask your genie "Why... how?..."
"Master, we'll have time for talk later. In fact, we have forever to talk. Become Jupiter!" she shouts, as she does the last snap you ever hear. You suddenly find yourself in the middle of darkness, and you can't see your genie anywhere. Then, the transformation begins.
For a moment, you crave oxygen, but after that, you don't need it anymore, because you're dissolving. Dissolving into a gas you've never seen, but that you know it's hydrogen. It feels weird, being a formless gas in the empty vacuum... and then, you begin to grow.
You grow... and it never stops. You become bigger and bigger... moments ago, you had an average height, but now you're ten meters big. And it doesn't stops... you keep growing, at an incredibly increasing rate... A hundred meters... five hundreds... one kilometer... you'd crush a street if you were there. Ten kilometers, fifty... one hundred... you're inmense, if you could move you'd conquer the earth already, but you'll never be human again... A thousand kilometers... and you loose count. You just get lost in the bliss of growing into something bigger than Earth itself, for what seems to be hours... luckily, time is frozen... more... you grow more... you dissolve more... grow... dissolve... think...
And then... the growing stops. There aren't words in the human language capable of describing how you feel... how much was the diameter of Jupiter? Around one hundred and forty thousand kilometers wide... And to think you were a few less than two meters before... You're a giant, an absolute giant. You can feel the burning wrath of the Sun covering an enormous part of your unmeasurable surface. You would have died if you were a human, but as a planet, such a high temperature just feels... right. You're bigger than your former home planet. You could crush it in it's entirety if you could move... But why would it matter, you're a titan, just to rotate endlessly until the end of the universe...
And then...
