She runs into a study group

Sandry cautiously backed around the bookcase, looking for any signs of someone following her. She breathed a sigh of relief when no one seemed to.

"Ahem." the sound from behind her made Sandry jump. She looked round, to find she had backed up to a group of students sitting around a table.

"Sorry!" Sandry exclaimed, she turned to face them and threw her hands over her body to cover her skimpy underwear.

"What happened to you?" one of the girls asked.

"Well, my uniform was a bit too tight..." Sandry began.

"So you took it off?!" one of the boys asked.

"No, it sort of... Fell off." finding her hands not big enough to hide her body, Sandry grabbed a large book from a shelf next to her and opened it, holding it lengthwise down her front.

"Hey, maybe this is what we need." one of the boys suddenly said.

"What?" Sandry asked.

"We're trying to raise money to save the second hand uniform shop," a girl replied, "we were brainstorming ideas."

"And I think I've got the perfect thing!" the boy added.
