Jen walked quickly to gym, wanting enough time to get to the lockers before everyone else. As she walked, she noticed just how much her large breasts jiggled unsupported. "Jeez, this hurts more than I remember it," she said, attempting to stifle the immense shifting by holding one of her arms in front of them.
She soon arrived to her locker, but she was met with a surprise - someone had ripped up her sports bra! "What the hell?" she said, quizzically. By now, people had begun to enter, some laughing and joking, others making a beeline for the stalls to change.
Jen called out, "Hey, does anyone have an extra t-shirt or sports bra or something?"
"Yeah, I have another t-shirt!" one girl called out.
Jen turned around excitedly until she saw the shirt. It was huge, something along the lines of a 3XX. "Oh, hey, does anyone else have a t-shirt?" she said, to which a flurry of head-shakes and muttered no's were her answer. She begrudgingly took the shirt, and put it on.
She noticed the shirt went all the way to her knees, a huge white t shirt. It covered her larger breasts well, though, like a large sweater. However, this was soon to change. As her gym class got underway, she slowly noticed the jiggling and moving was heavier than normal, and her t-shirt was seeming tighter and tighter. She looked down, and was shocked at the sight that met her eyes.
Much like the last shirt, she could now clearly see her cleavage pushing out the stretched hole at the top. She also noticed the t-shirt, which once stretched to her knees, now seemed to fit her like an average t-shirt. But her breasts, they took up her entire downward vision! Jen heaved one up, it must've weighed almost 50 lbs! No wonder she felt so heavy! They also extended all the way down to her hips, huge and heavy.
As she was looking at the depth of her cleavage, however, the bell rang. She missed her chance to change clothes, as she now needed to hurry to her next class!
