Katie while heading home, smiling as she looked at the magical ring around her finger, couldn't help but let out a small giggle as she remembered what she did to Mean boy Timmy. Just then Katie heard a familiar voice calling her name, causing her to turn her body around.
"Did you get bigger?" A boy asked her, appearing the same age she used to be.
It took a moment for Katie to realize, but it was her friend Mike from school. Even though he was a boy, and she was a girl, gender was not an issue when it came to their friendship, because they lived close to each other, they often played together.
"Mike, I have something really cool to show you!" Katie smiled, "Can I come over right now?"
"Sure, my older sister is the only one home right now so it should be okay..." Mike answered back.
The two quickly made it to his house, knocking on the door. It took a while but soon a young teenage girl answered the door.
"Oh, I see you brought your girlfriend over today" the teenage girl giggled.
"Eww she's not my girlfriend Suzy, she's just a friend!" Mike retorted back.
"Whatever you say squirt" Suzy laughed as she rubbed her little brother's hair until he batted it away, letting the two though the door.
Katie recalls that Suzy was a freshmen in High school this year, making her about 14-years-old. Suzy though, taking a look over at Katie, couldn't help but notice she looked a little bigger.
"Hey Katie... did you get bigger?" Suzy asked
Katie didn't know how to reply, not wanting to expose the secret to Suzy just yet for now.
"Kids sure do grow fast huh" Suzy justified, "if only that was true for little Mikey here" she giggled. "Now hurry up and go play in your room, and try not to be too loud okay" Suzy finished, before heading back into the living room, plopping on the sofa, and resuming her call with one of her friends she left on hold on her cell phone.
The kids quickly went upstairs as they entered Mike's room. It was a normal room for a 7-year-old boy nothing out of the ordinary.
"So what did you want to show me?" Mike said, closing the door behind him.
Katie smiled as she lifted her hand reveling the ring around her finger. "This"
"... What about it?" Mike answered back.
"It's magical, it can make people bigger or smaller"
"No way, you're such a liar"
"Nuh uhn, it's true and I can prove it" Katie snarked back. Katie then quietly whispered to herself "I wish I was a year older."
Mike watched Katie, waiting for her to prove him wrong when he began to notice something. Katie feeling a familiar sensation sweep her body gasp as she felt herself expand once more as her body inched taller, limbs extending. Not only that but her mind began to fill again as she felt as smart as a 9-year-old would.
Mike jaw dropped open as he couldn't believe his eyes. "Woah! That was so cool!" he burst in excitement.
"See, I told you I wasn't lying" Katie grinned.
"Can you make me bigger too?" Mike asked.
"Sure, but only because you're my friend okay." Katie then said to herself "I wish Mike was a year older."
Mike gasp as he felt a sudden sensation flush throughout his body, with a sudden gasp he felt himself rise a little in height, as he tiny body began to stretch. Not only that but just like Katie, information seemed to pour into his mind as well.
"Woah" Mike gasped again as his growth finished, making him 8-years-old. Taking a look over at Katie he couldn't help but see that he was still a few inches shorter than her. "Even though we're the same age now, I'm still shorter" he said disappoint.
"Well... not exactly, I actually made myself a year older before I saw you, so really your still a year younger than me but..." Katie then made the wish to herself again "I wish Mike was a year older."
Mike gasp as he grew again, quickly sprouting up a few inches once more.
"Now we're both 9-years-old" Katie giggled.
Mike smiled as he realized that now he was the same height as Katie.
"Hey how about we both continue to get older?" Make suggested, not wanting to stop the feeling of the energy that was pumping throughout his body when he grew.
"Until how old?" Katie asked back.
"Hmm... how about until we're the same age as my sister?" Mike replied back.
"Okay!" Katie smiled as she looked back at the ring, this time she made a wish so that they would both grow at the same time, saying to herself "I wish we were both a year older."
The two kids gasped as the sensation pulsed through their body, causing them to grow another year in age. The two kids began to groan a bit as they felt their clothes becoming a little tight on their 10-year-old body.
"Hey Mike, do you have any bigger clothes we can wear? My clothes are going to rip if I don't take them off soon." Katie plead.
"Wait, I'm going to see if I can find anything in my parent's room" Mike responded before headed out.
Katie took this time to look herself in the full body mirror Mike had in his room, she had grown a lot since this morning. Mike then reentered the room, tossing a shirt over to Katie while keeping one for himself.
"I got us a shirt from my mom and dad's room that we can wear for now" Mike said.
"Okay, we'll hurry up and turn around a put your shirt on, and don't even think about looking over here." Katie demanded
"It's not like you have anything anyways" Mike sneered back.
The two quickly tossed and pulled their undersized shirts and pants off, but kept their tight underwear on though as they slipped the over-sized t-shirt over their body. The two now more comfortably dressed continued were they left off.
"I wish we were both a year older" Katie continued.
The two groaned again as they body stretched taller harder and faster they passed into the double digit of age. Katie though let out a small gasp as she felt her 11-year-old nipple tickle, and knew what was about to come.
"I wish we were both a year older" Katie continued.
The two now entered preteen as their body hit another growth spurt causing them to once more rise quickly in height. Katie once more let out another small gasp as she felt her chest thrust out a big, her once coney breast were quickly becoming A-cups.
"What wrong?" Mike said, noticing his voice was getting much different.
"N-nothing" Katie mumbled back, noticing her voice was changing as well. "Anyways, let's continue, only two more years." Katie grinned before saying, ""I wish we were both a year older"
A teens gasp a Katie felt puberty rush through her body even harder, her breast continued to swell as her hips now began to flare outwards casing her butt to widen with it. Mike was enjoying his own growth as he felt stronger as muscle began to develop on his once lanky arms. The two 13-year-olds gasp they looked at each other body.
"Wow we gotten so big" Mike said, taking a look over at Katie body more than he did his own, couldn't help but feel a strange pleasurable feeling as he did.
"Yeah" Katie replied, taking a glance at Mike body, but started to look at him differently then she used to. "Just one more year and we'll be the same age as your sister." With that Katie continued as she said once more "I wish we were both a year older"
A moan escape both their lips, Katie felt as her body become even more developed and curvy, her breast finally pushed out to sizable B-cups, as her butt continued to round even more, causing her incredibly tight panties to sink between the crack, and was really more like a thong on her now. Katie was becoming ever more sexy as she blossomed into a teenager. Mike also was busying having his own growth as he stretched even taller clearly rising above Katie height by now. The two finished their sudden growth as they began to catch their breath.
"I can't believe I'm the same age as my sister now" Mike groaned, his voice was a little deeper now at the age of 14 than when he was 13.
"Yeah, this feel's so amazing" Katie gasp her she stretched her figure
Mike eyes was now lock on Katie's body as he felt his hormones begin to pump. "Hey Katie... can I touch them?"
"Them?" Katie answered back, but her body began to feel warm as she felt Mike's glare.
"Your boobies"
"Okay, but only one touch okay." Katie answered as she felt her own hormones pumping through her body.
Mike reaching out with one finger, poked one of Katie's hard nipples making her let out a gasp as a pleasurable sensation swept through her body. Katie rolling her eyes back down gasp as saw Mike's underwear.
"Oh my god! Do you have a boner Mike?"
"I-it's not what you think, I just can't control it" Mike fumbled trying to hide it with his hand.
Katie though felt her heart race as she said, "Can I touch it?"
"Huh?" Mike answered back.
"Well you got to touch my boobs, so it's only fair if I get to touch your penis as well right?" Katie flushed.
"F-fine" Mike said as he moved his hand away.
Katie crouched down as she looked at Mike throbbing junk in his incredibly tight whity-tighty. Extending one of her fingers, she poke at the hard mass as she gasp as it throb even harder.
"T-There you touched it so we're even okay" Mike fluster trying to return his hand back to cover it.
"Not yet, I want to get a closer look" Katie insisted as she could no longer control herself as she felt herself grasped the top of the whitey-tighty, pulling it down slowly, allowing Mikes hard stiff member to whip out into the open air. The two let out a small gasp as Katie found herself looking intensely at the swollen dick in front of her. Reaching her hand out this time, her wrap her fingers around the dick as she began to tug it ever so slightly.
Mike let out a grunt as he rolled his head back, he couldn't believe that his friend was now giving him a hand-job.
Katie couldn't stop as she began to pick up speed, pumping his dick faster and faster.
"Oh my god Katie!" Mike groan, "You need to stop, I-I can't hold it back anymore. H-here it comes!" Mike grunted as a loads of cum erupted from his dick, shooting across the room, landing on the floor.
The two teenager looked at each other, both trying to catch their breath.
"That was amazing Katie" Mike said as he plodded onto his bed, feeling slightly tried after blowing that massive load.
Katie though stood up as she went to the full body mirror, looking over at her teenage body, it was cute, but she wanted to be even older, and not just a little older. Taking off her shirt, but leaving the incredibly tight underwear on, she then said "I wish I was 7 years older".
Katie began to moan as she felt her body continue to force its way through puberty. Thrusting her chest out once more and heaves as she felt her tits swell larger. Mike jaw dropped as he watched his 'friend' grow from behind, his eyes were at her heart-shaped ass which pushed out and widen, becoming more round as it finally snapped the panties in half, letting them drop on the floor in tatters. Her child-bearing hips flared out, as her waist remained thin. Her tits exploded off her chest becoming large D-cups. Her legs were long and shapely, matching her incredibly curvy body.
Katie smiled as she looked at her now full grown buxom 21-year-old body. Looking at the reflection in the mirror, she can tell that she wasn't the only one enjoying her adult body.
"Do you like what you're seeing? Katie asked, her voice now a sexy low which match her body.
Turning around she didn't need a response seeing how hard Mike was again.
"Mind if I join you on that bed?" Katie giggled, of course she didn't wait for an answer as she climbed on top of it. Katie quickly gripped Mike's t-shirt, before stripping him of it. Running her finger down his chest, and to his cock, she couldn't help but feel that it was... a little small now.
"I think you need a little growth spurt yourself as well" Katie said, the followed it with "I wish Mike was 7 years older".
Mike began to moan as Katie forced his body into adulthood. She couldn't help but smile as she saw his dick grow longer and thicker with every throb, making her more and more wet. Mike are continue to get stronger, as his shoulder became more broader.
"Oh, Mike you're getting so big! So huge! Katie gasped as she wrapped her finger around his growing girth.
"Does that mean I get another hand-job?" Mike smiled, finally reaching 21-years-old just like Katie, his voice deep and mature.
"I have a better idea" Katie smile as she rose her body, hovering her pussy just above the tip of Mike hard cock. Katie then began to push her hips down making her moaned deeply as Mike's giant cock thrust inside of her tight wet pussy. Mike rolled his head back in pleasure as he gripped Katie's wide hips rotating his hands back in order to give her firm round ass cheeks a mighty squeeze. Slowly easing in to it, Katie now began to ride Mike hard on his bed.

Suzy was still downstairs talking to her friend on her cell phone, couldn't help but hear a loud squeaking sound coming from upstairs. Suzy was just going to ignore it at first, but it was starting to annoy her as she let out a low growl.
"What wrong" a voice asked from the cell phone.
"Oh nothing," Suzy answered back, "It's just my pipsqueak of my little brother is playing with his friend right now, and even though I told them to play quietly, they decide to start jumping on the bed for some reason" She scoffed.
"Well are you going to do anything about it?" the voice asked again.
"Hmm..." Suzy wondered.
