An old oil lamp made of silver. You found it on the trash, and you know very well how they may work: a genie will probably pop out of the lamp and grant you three wishes. And even if no genie comes out, it's still very shiny, polished and well done, probably worth some money. Plus, even though it was on the trash, it's absolutely clean. There's no reason not to keep it.
Tonight you're going to be alone at home, so you decide to lock yourself in your room, and try to rub the lamp to see if a genie comes out. You take the best cloth you could find, fitting for such a pretty object, and rub the lamp with it. It begins shaking, and some moments after, blue smoke comes out of it's tip. The smoke grows bigger and bigger until it reshapes into a woman with blue skin, black eyes, a big ponytail of black hair which reaches her waist, and a simply perfect body. She's dressed in beautiful silk clothing, which covers just the needed parts of her body, leaving the rest bare. You stare at her in awe, and then she begins to speak.
"Greetings, Master. I am the Genie of the Possible and Impossible." she presents herself. "As you probably know, genies grant three wishes... I can grant you three wishes as well, no matter how crazy, unusual or impossible it may be, and I won't twist them for amusement. However, you need to narrate your wish in a proper and detailed manner instead of saying something vague, because I wouldn't be able to grant it like that." she explains.
"Wow." you answer, and no more words come out from your mouth. She certainly doesn't looks like the kind of genie who would cause mischief, but someone who is loyal and servicial. You've got too much power which will bend to your will. After thinking for a while, you're ready to make your first wish.
