Katie kept walking, pushing through her tween years. She got taller and thinner as the last of her baby fat drained out. As she finally hit her teen years at 13, she felt a tingle in her chest. She looked down to see that her nipples were making slight indentations in her tank top. As she walked, her nipples rubbed against her tank top more, feeling more sensitive as they did. The areas around them started getting more puffy as tissue began forming. "I'm growing boobies," said Katie, her mind expanding to explain what puberty is. The discomfort faded as a training bra appeared under her tank top, comfortably cradling her nascent breasts.
The beginning of puberty spurred Katie to walk even more, wondering how big she was going to get. As she continued through her teen years, she gained more height. Her legs became more shapely as her thighs and hips start filling out. She could feel her butt growing into a more appealing shape. Her tank top pulled up more, showing her belly button. Her training bra became a proper bra as her breasts expanded, putting her into the upper B's. Katie's face got prettier as her lips became fuller and her face started losing its roundness. Her hair grew longer before a band put it into a ponytail. At 16, Katie was becoming a looker and she knew it. "Sweet sixteen and ready to drive," she said proudly, her voice not sounding as high-pitched as before.
She soon felt like it is enough and hit the stop button to end the game. Getting off the treadmill she checked every part of her body and was in awe at the changes. "Wow... Check me out! I'm a straight up teenager with a hot teenage body. Bet mom never had a body like this."
Saying that, she thought calling her mother sounded strange to her. Indeed, Kellie gave birth to her at 22, but that was eight years ago. Now thanks to the treadmill, in Katie's head, her mother gave birth to her at 14, too young to bear children, but one accidental night to loose her virginity caused her to have an early pregnancy. Which is why with the support of her family and friends and getting a job as a fast food cashier at an early age, helped her work hard to support her daughter when she was born. Balancing between high school student and mother, she continued to get more odd jobs to help her get to college while providing for Katie. Now a single mother of thirty, now owns an indie clothing store in the same mall that arcade is located in and sacrificed everything to help Katie become responsible for herself and not repeat what she went through.
With all the altered memories in her head, Katie placed her hand on her chest and gave a deep breath. "Mom really worked hard to support me. I couldn't help but be proud of her sacrifice. That's true love..." Thinking that, she soon turned and walked out of the arcade, feeling happy that she has a mother that loves and support her. As she left the arcade, she wondered what to do.
