Obviously a Scam

Obviously this was a scam, Jason figured. Obviously somewhere had to be a cam, and they were filming him. Obviously this was some very convincing trick that made the girl appear to be partly smoke coming from a lamp. Way too stereotypical to be real, obviously.
"So I got like three wishes now?" he joked nervously.
"Actually as many as you like." the smoking hot girl that introduced herself as Aza returned.
"I guess this is the point where I wish for a huge dick now or something?" Jason laughed, but Aza stayed firmly in character.
"Define huge please." she chirped back, causing Jason's brain to struggle.
"Uh... don't know... what do guys wish for these days? Like uh... 12 inches?" Jason felt how he was sweating. He knew it was some kind of a hidden cam scam, and that would certainly have to get them to come out and he could surely tell everyone that it was just a joke, right? Not that he wouldn't mind if it was real, but it couldn't be, obviously.
"As you wish." Aza said with a smile.

An awkward moment of silence passed, where Aza knew what had happened, yet Jason took his time, while realization slowly crawled up his spine, and begun to manifest in his brain. That weight he was feeling on his groin, that warm lump of flesh leaning against his thighs, the vast amount of fabric of his jeans he felt rubbing over the skin of his dick, that hung out of his boxer shorts by at least half his size. He wanted to look down, but in a **** effort the last sanity of his mind insisted that this just couldn't be happening, that it was impossible to just magically grow a gigantic cock out of nowhere.
"You can check, it's fine." Aza's warm smile finally got him to tilt his head down. And what he saw down there felt like a dream: a massive piece of meat bulging his pants down to his knee. Unmistakably his dick, even though every part of his mind told him that this just couldn't be happening. There had to be another explanation, there just had to! But when he finally, awkwardly run a hand over his new appendage, reality collapsed in on him: he indeed now had a gigantic dick. And in conclusion somehow now also a sex genie willing to fulfill his wishes.

"C-can I even get still hard with this... thing?" he stammered.
"Yes, I grant all wishes with the best intention for your." Aza explained.
"I.... d-don't feel like I can." Jason felt his legs shaking.
"It's because you are nervous, let me help you." she had this calming smile on her face again and snapped her fingers. Instantly Jason felt blood rushing down to his cock, and while he wasn't blacking out or anything, he did feel like his brain came to a halt for a moment. Down there his dick was raising fast, tenting his pants obscenely, when suddenly he felt like an invisible hand was pulling his cock up to free it from the restraints of the fabric. With the chains now unlocked his dick continued to grow rapidly, till he sported a throbbing boner that easily reached to his chest, bulging not only his pants but also his shirt unmistakably.
"Don't worry, the reality filter is in place." Aza did her best to ease the situation "They will see it, but they will think it's perfectly normal."
