She thinks Lila exposed her underwear

Luckily no one was behind Lila to get flashed but Cheryl suspected something was up with Lila. She was tucking her hands again even though the room was quite warm but Lila’s notorious prudishness made it so the idea that she wasn’t wearing a bra or panties nearly impossible to Cheryl. It had to be something else.

“Did you just accidentally expose your panties?” Cheryl said with a laugh as she noticed how uncomfortable Lila was.

‘I wish’ thought Lila.

“No! I just... my back hurt.” Lila was trying to think of a good reason for her jerky motion but couldn’t.

“You hurt your back?” Cheryl said incredulously.

“Yeah! I was just trying to be helpful and hurt my back.”

“Hmmm, why don’t you repeat the motion see if we can get to the ‘bottom’ of this?” Said Cheryl with a devilish grin.

“Thanks but I’d rather not hurt it again.” Said Lila nervously.

“Just tell me the truth: is it a thong? Is that really what you’re embarrassed about? I find it hard to believe a prude like you would wear just a thong with only that shirt?”

Lila didn’t even own a thong but right now she’d do just about anything for one. She’d also do just about anything to get out of this conversation.

“No it’s my back! please, you’re making me even more late, can I just go?”

“I don’t know, I think I might need to report you for a dress code violation. Why don’t we see how much room there is between the hem of your shirt and your panties?”

‘About 7 miles’ thought Lila, the distance between the school and Samantha’s house.

“Not funny, Cheryl, can I please just go?”

“Technically this is a dress code violation. If your underpants or bra would be exposed during the course of regular activities you should be written up for a uniform violation. Plus you’re tardy. You’re forcing my hand as far writing you up. Unless you show me the difference between the hem of your shirt and where your panties start.”

A write up would send her to the office and probably get her a detention plus the extra attention to her outfit might make the fact she was only wearing a t-shirt and flip flops more obvious to more observant eyes. She couldn’t expose panties she didn’t have to Cheryl and she certainly didn’t want to show her her pussy. She could turn and run for it but that might expose her ass and the walking required to maintain her modesty would mean she couldn’t get far.
