Shannon watched as her skin became smoother and younger-looking. Her body shrank a few inches in height, and her breasts became smaller as well. She felt her hips narrow, and even her shapely behind shrank, becoming a cute and heart-shaped. She'd lost weight overall, but she looked more fit as well. Joey recalled that Shannon had been quite athletic in school.
Shannon admired her body in the mirror, perhaps a touch longer than Joey had expected. Feeling more than a little aroused, he made another wish. "I wish Shannon really enjoyed being younger, and her own body turned her on."
The surprised look on Shannon's face was soon replaced by a wide, dreamy smile, amd she reached to caress her breasts. "Oh..they're so much more sensitive now." Soon she was making soft purring noises. "This feels so good, Joey...I can't believe how turned on I am. I wish I could take the bra off without changing back."
Joey didn't want to reveal his power just yet, so he made another wish.
"Did you say "I wish", Mistress?" An unseen and sultry female voice asked.
Shannon's eyes got wide. "Who said that?"
"It is I, the Genie of the Bra, Mistress. Now that you have worn me, I will obey your commands."
Shannon smiled. "Really? What can you do?"
"I can change your age, making you younger or reverting you back to your true age. You need only wear me to make your wishes, you can take me off and remain as you are. I can make adjustments to your body, making you shorter, taller, changing the color of your eyes or hair- and I can make certain alterations to your mind."
Shannon blinked. "My mind?"
"Indeed, Mistress. Say you wished you would become greatly aroused by Tennis players. It would be so."
Shannon got a goofy grin on her face. "Just like that, you could give me new kinks, or take them away?"
"Indeed, Mistress."
Shannon turned to face Joey. "Hey, I can keep this bra now, right?"
Joey grinned. "Of course, my gift to you."
The smiling 15 year-old gave Joey a kiss in appreciation. She probably wouldn't have normally, but it didn't help that she was obviously feeling frisky.
"Ok Genie of the Bra...uh, do you have a name?"
"No, but you may give me one." The Genie replied.
"Hm, so what's a good name, I know. I'll call you Brandy."
Joey rolled his eyes. Brandy had been Shannon's rival in high school. Just as pretty, but with larger breasts. It probably gave Shannon a thrill to boss Brandy around.
"Then I am Brandy, Mistress. What is your wish?"
"Well, checking myself out, I'm really turned on. So I was wondering what it would be like to have sex with a girl. I wish I was a lesbian!"
'What, wait...' Joey thought to himself. 'If she's a lesbian, then I can't have sex with her! Though, the idea of Shannon having sex with other girls...' Joey felt his cock become even harder, uncomfortably so. He didn't want someone to notice, he'd be so ashamed! "I wish no one would notice I have a hard on!"
That helped, but it was still uncomfortable to move. Maybe it was the fact he was in a lingerie store, but he had an idea. "I wish I had a vagina instead of a cock!"
There was an odd tingling sensation in his crotch, and it felt like something was sliding inside of his body! It felt really good, and he couldn't say or do anything as his dick shrank in size, retreating into his body, until there was nothing but smooth skin. Then, he felt the skin part and a pair of lips form as he found himself the owner of a pussy! Begging that he had to go to the bathroom, Joey retreated into the nearest lavoratory. The crotch of his jeans was deflated, and he felt very strange as he moved- it felt really good, but it was weird at the same time,
Stripping off his pants and underwear, he got a good look at his pussy. It was a little hairy, so he wished away his pubic hair. It was small and kind of cute looking, and he had to open himself up to get a good look at his clit. The touch felt amazing, and he started to stroke himself.
"I wish...uh...no one would think it's weird that I'm in here...for so long.." He started to gasp. But what would Shannon do in the meantime?
"I wish Shannon would have sex with Sarah!"
With that out of the way, he continued to masturbate, sitting down on the toilet seat as he felt his legs wobble unsteadily.
