Katie gathered a new change of clothes and headed to the changing room to sit down. Along the way, She 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. Her legs took the same direction as well and grew longer with muscles swelling to young surf girl status. 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 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. Just as she was looking at herself, she could feel a little discomfort in her mouth. Opening her mouth, she noticed braces appearing on her teeth. Katie was surprised by that and wondered how that got there. That’s when she remembered her memories altering. She remembered that she needed braces to help straighten her teeth. That could explain why she had them in the first place. She then noticed the skin on his face as saw a little dot on the cheek. Was that a pimple? She heard of teen girls getting them, but she never thought it was possible for her. Guess it was a price to pay when growing up.
She clipped on her bra and watched as her body expanded to fill it, now 5'9'' and having hit the sweet sixteen mark. Her breasts grew to B-cup size as she enters the threshold of child to adult. Her hips and buttocks expanded further as her waist curved inward to create a much curvier hourglass. Her arms and legs gained more feminine muscles as her biceps were bloating and her calves were bulging with years of jogging and push-ups. Her face continued to mature as her lips started to puff out and her nose grew long and thin. She did notice further pimples dotting her face only for the aging to pick up speed and the zits to fade away to be replaced with smooth flawless skin. Even her hair grew fuller as it went down to her mid back. Her brain kept on filling with high school knowledge as history, math, English, and social studies felt easier for her. But her athletic knowledge continues to dominate more of her brain as memories of her taking on karate, track, and volleyball now entered her mind. The seventeen-year-old watched on and was amazed by how her body has grown and developed. If it’s possible, she might be able to surpass her former mother’s body.
As her body crosses the six foot threshold, Katie could feel her C-Cup breasts getting squeezed in a bra that is one size too small as her hips expanded further and her rear inflated bigger to grant her a curvier hourglass figure which were hugged by her new jeans and midriff muscle shirt. The muscles on her arms and legs grew thicker and harder and although they are not body builder level, she does show that she was very athletic. Her face left childhood completely as her skin as clear and shiny, her nose was very elegant, her lips puffy and defined, and her eyes looked sultrier and less innocent. Her hair was close to her back and darkened slightly to match with her looks. Her mind matures as well as knowledge and memories were changing incredibly. Most of which involve sports as she now knows how to do the hurdles, light weight training, and yoga to make her feel flexible. The nineteen-year-old woman stepped forward to her newfound older sister and said: "Come on, let's buy the new clothes and go home."
