"I wish I had a bigger dick!"

"Why not, this should be a good test to see how this all works. I wish I had a bigger dick!" Jake says to Jean, whose response is a look of disappointment.

"Another one of those huh? I guess it does have its perks." With a snap of her fingers, the wish is granted. Small pink sparkles surround her finger tips, slowly fading away after the snap. Jake sees this and realizes his snappy wish might actually come true.

Just then, he feels something strange in his pants. A tingling running through his pelvic region, before shooting straight into his dick, causing it to stand on end. His pants strain at the hard erection, forcing Jake to undo his belt and drop them to give him some breathing room. "Oh shit!" He groans, feeling an intense heat coursing through his cock.

He looks back up to Jean, who watches with an excited curiosity. "Even though it's the most common wish I grant I still can't help but admire my work~"

As he looks back down, Jake sees his dick finally starting to expand, furthering its previous limit. His fairly average dick almost doubles in length in mere seconds, causing him to have to cover it with his hands to avoid Jean seeing it. "W-Why are you just watching?"

The Genie giggles. "You know I'm a Sex Genie right? You understand that? This is what I live for..."

Finally the change stops, and Jake is left with what looks like a 10 inch cock, fully erect and stretching out his underwear. He tries to keep it contained, but the increased blood flow inside is keeping it as hard as a rock.

"There you go, a perfect cock fit for a stud." Jean says. "Now you can go use it for... Whatever you're planning on using it for. Maybe you want to make another wish? Or is there someone you already plan on fucking naturally?"

Jake falls back onto the couch, his 10 inch monster sticking straight up. "I didn't really have a plan for this- It just kinda popped into my mind."

"Naturally." Jean says with a smile.

Just then, a door upstairs opens and closes, followed by footsteps. The annoyed tone of Jake's sister Holly can be heard from the top of the stairs. "Jake? You okay? I heard yelling."

Jake tries to answer, but fails to come up with something on the spot. The crazy situation is messing with his mind. "I- Uh- It's nothing!"

Holly sighs and starts walking down the stairs. "You didn't break anything did you?"

"Shit, Jean get me out of this!" Jake turns to the Genie, pleading.

She just sits there with her arms folded. "Sorry man, you gotta use a wish for that."

"Oh come on! Really?" Holly's footsteps grow closer to the bottom of the stairs. "Fine! I wish you got me out of this!"

"Okay!" Jean says with another snap of her fingers.
