As she arrived at school and got off the bus, she ran into her friend Evelyn. They began their morning ritual of walking to class talking while quickly consuming the coffee that Eve had picked up on her way to school for the duo. As they reached the point where their paths split, they stopped, and Jennifer turned to give her friend the usual hug. Unfortunately Eve had her coffee in the hand closest to Jennifer, and Jennifer's increased endowments decided to knock the coffee off-kilter in Eve's hand.
Eager not to lose her coffee, Eve tried to hold on to the coffee. She failed, and only made the fall-out worse. Instead of seeking the ground, the coffee had now been flung in the air, with a trajectory straight towards Jennifer's ample cleavage. The better part of half a warm coffee now thoroughly soaked her top.
Eve began apologizing, "I don't know why I had the cup in that hand! It's not like we don't do this almost step for step every morning!"
Jennifer quieted her friend, "Don't fret, I've got a spare shirt in my gym locker. Here's my coffee, any chance you can explain to my teacher what happened?" Eve nodded quickly. She was on the Student Council, so teachers tended to believe what she said more than the average lying highschooler. It came in handy for Jennifer in situations like these.
Jennifer headed to the gym as quickly as she could. Luckily classes were starting and most of the students had found their classrooms. Gym classes wouldn't be starting quite so early, so she would be alone in the locker room to clean up.
As she got into her locker, she assessed the damages. Her pants had been spared, but her top and mom's bra were ruined by the coffee. She resolved that she didn't wish to wear a sports bra all day, so she decided to go braless. She quickly pulled her shirt over her head and started back toward class. Unbeknownst to her, the curse began its work. Her breasts gradually began filling out the front of the shirt, until her cleavage was clearly visible through her collar. Instead of fitting her, the shirt now clung to Jennifer's breasts, tapering off into her waist.
She got to class, and her teacher waved her to her seat. It seemed that Eve had indeed smoothed things over with her teacher, and she would be free to attend class without punishment.
As class began, Jennifer kept running into minor annoyances. At first her breasts had been blocking a portion of text she had been trying to read. Then, as she was taking notes she kept bumping into her boob as she was writing. Overall, her annoyances were manageable.
As the bell rang, she packed up her stuff and headed back to the gym for her next class.
