PE

"At least it's PE next." Robyn shrugged, "You’ll have some clothes to put on."

With a minor sense of relief, Sandry grabbed her gym bag from her locker and the two of them made their way to the changing rooms. Amid the titters and whispers of the other girls at the state of her uniform, Sandry found a free space at the back. Her skirt was just a piece of fabric so she dropped it on the bench, and as she pulled her blouse off it tore on the seams, making her doubt she would be able to put it back on again.

Sighing, Sandry opened up her bag.

"Oh no."

"What is it?" Robyn asked as she stripped off her own uniform.

"This isn't my kit," Sandry said, pulling out a pair of black shorts several sizes too small, "it's my sister's."

"Oh, dear." Robyn tried to supress a giggle, not entirely successfully, "This really isn't your lucky day, is it?"

"What do I do?"

"Well, you’ve already got your sister's knickers." Robyn smiled at the sight of the grey teddy bear on the front of Sandry's pink panties.

"These are mine." Sandry blushed, "They're just a bit old." She looked at the other girls, already changed and making their way out of the room, "What am I going to do?"

"I don’t think you have much choice."

Realising she was right, Sandry began to struggle in to the small t-shirt and shorts.
