Katie wasn't appreciating this new sister of hers. She needed some kind of change. Maybe if she and her sister were closer in age, they would get along better.
"I wish that I would age and Kellie would regress until we were one year apart." The ring began to glow.
Katie could feel another growth spurt coming as her height jumped to three to four inches. But she could see other changes on her body that takes her straight to womanhood. The small mounds on her chest started to grow as they look like pointy cones. Katie saw them sticking out and could feel her hormones ramping up as the nipples started to look erect. Her hips started to flare up a bit and were gaining a bit of curves around her waist. Her arms and legs stretched as her skin was toning up and darkening in a glazed like tan. Looking to her review mirror, she could see her face maturing as she was entering her teens. Her head was looking shaping from a round to oval, her nose grew bigger and thinner, the freckles continue to fade bit by bit, and her eyes were getting smaller and more mature. She flinged a few blonde strands back as her hair slowly grew down her neck. Looking down at her feet, she could see her worn out sneakers looking new again and adjusted size to fit her growing feet. The thirteen-year-old was enjoying this as she was starting to grow out into her teen years.
Katie watched as her 18 year old mother drove the car with the exuberance of a girl looking forward to her first day of the summer. Glancing at the young 18 year old Katie marveled at her appearance. Kellie was a trim an athletic looking viral with golden blonde hair and a deep tan. Her breast size had decreased slightly but had become perkier. Unfortunately she saw katie as more of a nuisance than a sister.
Katie decided to turn her attention back to herself. She could feel her body growing again as she could feel another growth spurt happening, shooting up another couple of inches. Her body then continued to mature further as her cones upgraded to size A cups, small but round. She could feel her hips expanding as her waist gotten a little curvier then normal. Tracing her finger to her hourglass, she was amazed at how shapely she’s becoming. She then spotted her fingernails and noticed that they were extending while her hands grew big and dainty. She could even see the nail polish on her nails as the pink began to sparkle. She looked at the polish as the sparkle reflected on the shine, feeling amazed by it all. She checked her face again and could see its journey through adulthood. Face looking so much oval like, nose getting longer and thinner a faint freckling on her nose, and eyes smaller and less childlike. She also noticed her lips puffing with cartilage and darkening to give her something to be kissed with. Her hair started to grow longer as it brushed past her shoulders and was getting brighter by the second. Her floral print bikini shifted to match her body as it changed into something more mature at the floral designed faded and replaced with a navy blue color. Her sneakers shifted a little more as the laces vanished and the top opened up a little, turning into teenage flip-flops. Then her surfboard grew a little to match her age and looked like ones for teenagers. Katie watches it all as the 14-year-old stretched a little, enjoying her changes bit by bit.
Kellie sighed as she went from 17 to 16. The young girl was sighed and looked back up the road. "Why can't we be there already," the teen whined. Katie suppressed a giggle at the sound of Kellies voice. It now had that whiny teenage tone to it. The teen had shrunk again leaving her only a few inches taller than her 14 year old sister.
Katie now felt her body growing more pronounced as she raced through the teen years. Her growth spurt got to a couple of more inches and she could feel like she was rising on the elevator. Her chest started to feel heavy as she looks down to see the mounds growing bigger and looking like AAs. Hips widening and curving as she had the hourglass of a young teen. Katie crossed her legs as she could feel them growing longer and shapelier, letting her free foot dangling as she moved her dainty foot to the beat. She looked to her hand to see it changing shape with fingers getting thinner and longer and her nails extending further. Katie decided to look at the dashboard mirror and see if the face has changed much. So far, she could see it maturing more, as her cheeks look less puffy, her nose thinning to a sleeker shape, lips puffy a little bit, and her eyes and ears growing smaller. Starring at herself, she was starting to look like such a beauty.
Finally, Katie was just a year younger than Kellie. Time to see how she was treated.
"So, what are we going to do at the beach, sis?"
"I don't know," Kellie replied. "Surf, sunbathe, maybe look for some boys. She giggled and winked at Katie.
Much better, Katie thought. Now this was something she could get used to.
