Jodie has also split her pants

As Sandry stood there watching Jodie bend over to her locker, she saw the grey material of Jodie's trousers seat stretch taut, the darker grey of the stitches suddenly grow more visible, and as she realised what was about to happen sure enough the stitches began to snap, one after the other in quick succession, the seam parting to reveal an oval of bright pink cotton.

Jodie jumped up, holding her PE trousers.

"Did I..."

"Split your pants? Oh, yes."

"Oh my god, that's so embarrassing!"

"Yeah, I know."

"I suppose you do."

"So, if I could just take those trousers and go get changed..."

"What?"

"The trousers you said you'd lend me."

"I can't lend them to you now! I need them myself!"

"But you already said..."

"That was before this happened!" Jodie looked around, aware their conversation was getting louder and starting to attract attention, and that's when Sandry seized her opportunity. She grabbed a dangling leg from under Jodie's arm to pull the garment away.

But Jodie reacted faster than she expected, held the other leg firmly, and in a moment both girls were stuck in a tug of war, the jogging trousers as the rope.

"Give them to me!"

"No, they're mine!"
