After the movie, Kellie and Katie walked out of the movie theater along with the other couples. The theater wasn't far from Kellie's house, so they were heading in that direction. Kellie wasn't thinking much about the movie they just saw. She was thinking more about the strange ring she had found earlier, which had the power to change people's ages. She felt like she had used it before, but she couldn't exactly remember when. But anyways, she was planning on telling her best friend about it.
As they got to Kellie's house, Kellie said, "Katie, there's something i need to show you." She held out her hand to show the ring on her finger.
"Ooh, pretty ring," said Katie.
"It's more than pretty, it's magic," said Kellie, "I can change people's ages."
Katie raised an eyebrow at that and asked, "Are you kidding?"
"No, I'll prove it," said Kellie, "I wish you and me were three years older."
The two 10 year-olds felt a jolt go through their preteen bodies. They could feel them getting taller and their baby fat disappearing as they aged to the brink of puberty. A slight tingle in their nipples showed them where they crossed the threshold. They didn't have real breasts yet, just puffy, tender areas.
"Wow, it worked," said Katie with amazement, looking down at herself, "I wish I could see myself."
"Come inside and we'll look in a mirror," said Kellie. As the two 13 year-olds walked up to the house, they both noticed a new level of attraction towards each other. Katie was noticing Kellie looked prettier than before and her eyes found themselves looking at Kellie's rear more often. Kellie was aware that her friend was looking at her and she was glad she was in front so Katie didn't see her blush. She found the attention rather flattering.
Before long, the two of them were looking at themselves in the mirror in Kellie's room. Katie rang her hands down her sides, noticing the slight curve she was feeling at her hips. "I can't believe we really grew," she said before turning to Kellie, "Can you make us grow more?"
"No problem," said Kellie, "I wish we were four years older." The two of them gave soft moans as they started to get taller. What puberty had just started was now getting closer to finishing. Their hips expanded to the sides while their rears plumped into appealing shapes, which complimented their now-shapely legs. Arms grew longer as their hands became long-fingered and dainty. Their heads lost their roundness as they took on a more adult oval shape, with their faces maturing to match. What caused most of the moaning was the way the puffy areas around their nipples were swelling out into new breasts, filling up their training bras which soon morphed into real bras along with the rest of their clothing adjusting for age. Their breasts filled out to be quite a handful, but a slight bit of cone-shape was still left in them, indicating they had more growing to do.
"Oh wow," said Kellie, looking down at herself, noticing her maturer voice, "We look so hot now."
Katie spun Kellie around to face her. "I have to agree," said Katie, "You're particularly irresistible." Quite suddenly, she leaned in and placed a kiss on Kellie's lips.
Kellie was surprised for a moment before she found herself kissing back. The attraction the two of them had felt before had evolved into something sexual. Their breasts started to bump together while their hands went up and down each other's body, feeling their trim waists, wide hips, and bubble butt. Eventually, Katie pulled back and purred, "So, how about making us a little more grown up, babe?"
Kellie nodded and said in a breathy voice, "I wish we were five years older." They both let out a moan as their bodies rushed to finish puberty. Their breasts grew larger, pushing against each other. They put on a bit of height, but most of their development went into filling out their curves. Their hands gripped each other's asses as they filled out into full sexy shapes. Before long, the two of them had matured into sexy young women.
Kellie looked at the adult Katie and felt such a fire fill her loins. "Katie, I need you so badly," she whispered.
"I know, I need it too," whispered Katie before they quickly hurried to Kellie's bed. The two of them started removing their clothes in a hurry, only slowing down to rub their partner's body. When they were both naked, they started stimulating their bodies as much as they could, both of them giving loud moans of pleasure as their arousal grew.
At one point, Kellie was lying back as Katie suckled at her breast. Kellie looked down at the sexy naked young woman at her tit with a smile. But then an odd memory seemed to flash through Kellie's mind. She could imagine a much, much younger version of Katie, a newborn, suckling at her nipple. Likewise, she saw herself as much older than she was right now. Kellie frowned a bit at the unfamiliar memory that seemed strangely clear. But her train of thought was soon crashed when Katie slipped two fingers into her vagina and started stroking it.
The two of them went at it for most of the night, changing positions quite often. Eventually, the two of them fell asleep in each other's arms. There were no parents to walk in on them or children who might peek. Just a pair of lesbian lovers sleeping in their own house.
