He doesn't believe her, at first

The Genie couldn't help but raise an eyebrow at Derek's laughter. The young man wiped a tear from his eye as he struggled to stand. "A genie?! Really?! You expect me to believe that?!"

"Well...yes, of course," the Genie said. "I am standing before you, after all."

"Come on! That's impossible!" Derek said. "Who put you up to this? My sister, Jean? That rich chick, Kayla?"

"I am not familiar with this Kayla or Jean," the Genie said.

"So, what?" Derek asked. "You made a few magic tricks and thought you'd make a prank video? Where's the camera? No, wait, what's your real name?"

Despite her master's disbelief, the Genie felt a small sense of happiness at being asked about her name. "Many of my masters have not asked that. My name is impossible for a human to pronounce, in any case. Typically, I am given a name to respond to."

Derek rolled his eyes. This game was getting annoying. "Okay, then. How about I call you Lavender, since your lamp smells like it. And if you are a Genie, here's my first wish: I wish you could make your clothes disappear!"

The Genie, Lavender, felt annoyance at the wish. Just like her previous masters, this one was eager to see her naked. "As you wish, my Master."

With a snap of her fingers, Lavender's clothes vanished in a puff of violet smoke. Her hair tie vanished too, letting her green hair fall down her shoulder. She stood with her hands on her hips, showing off her bare body to her Master.

Derek felt transfixed, staring at her perky B-cup breasts and bare pussy. "Holy...! You're actually...You just...!"

He suddenly realized he felt very cold. Taking a look at himself, he realized his own clothes had disappeared as well. Derek yelped in shock and covered his growing seven-inch dick. "Why did you get me naked too?!"

"Genies can alter wishes in a way that suits them," Lavender said. "I believed it was unfair that I was unable to see my master's nudity."

Dereks mouth had yet to close. He was still in shock. "Oh my God. You're actually a Genie!"

"As I kept saying, master," Lavender said irritably.

Derek felt a growing sense of guilt, coupled with embarrassment. "Hey, look, I'm sorry, okay? I'm not a pervert, okay? I thought you were playing a prank on me, and I wanted to call you out. I get pranked a lot, and if I knew this would happen..."

He noticed Lavender's cheeks turning a darker shade of blue. "Um, look, you can bring our clothes back, now. I unwish my wish. I wish for our clothes to come back."

"It's not that simple," Lavender said. "Once a wish is made, it lasts for a number of wishes to make sure the master is happy with his decisions."

"Are you kidding me?!" Derek shouted. "How many wishes do I have to make before I can undo this?"

"Quite a few," Lavender said.

Derek gritted his teeth in frustration, wondering how he was going to explain this to his family and friends if they caught him naked in the attic with a naked Genie. He looked up at Lavender and said, "Look, I really am sorry. You don't have to keep posing for me if you're embarrassed."

Lavender crossed her arms to cover her breasts and crossed a leg in front of her vagina. Her blush started to fade, but not by much. "I suppose I can understand. This is hardly the most embarrassing wish I have granted."
