The next morning, you wake up, and feel a weight of sorts on your chest. Looking down, you see your chest has grown, not too much, but a noticeable amount. Jumping out of bed, you go to your closet to get a look. They were about a small B yesterday, but we're now firmly B cup status. Luckily, most of your clothes still fit, and you make a note to ask your mother to go shopping sometime next week.
Over the next couple of days, your breast continues to grow at an impressive rate, by the end of the school year, they're a solid C cup, and you've noticed your popularity with the boys have increased drastically, no doubt because of your beauties.
Throughout the summer, you resort to using your mother's bras to encase them, but even then, you quickly surpass them. By the time your sophomore year start, you have the biggest bust size of your grade.
You've also caught your uncle staring at them sometimes, oddly enough, but you try your best to ignore it. James has also started talking to you, and you feel you now have a chance, especially now that him and Jessie have broken up.
After a party the day before school starts, you lay down, happy with the way your summer went, and happy that you're breast have slowed down at their ample size. You lay down and sleep, excited to see your friends again.
