Hide in a toilet cubicle

As well as the urinal against one of the walls, there were two toilet cubicles in the boy's bathroom. Grabbing her things Anna dashed into the nearest cubicle and closed the door. Her heart was pumping fast; she could feel it beating within her ears. Holding her breath, she waited for the cry of surprise to indicate that somebody had seen her brief streak. After a few moments she gasped in relief. The boys were talking about the practice and how well they'd played, but none of them seemed to have noticed her.

She slipped the lock into place. On the back of the door was a clothing hook which she used to hang the shirt. The arms and chest area were dry now although the area beneath the chest was still wet through. She slid the phone into the shirt's breast pocket and draped Claire's bra over the top of the hook. The toilet seat was raised up, so Anna eased it down and sat on top of the lid. Her bare behind and crotch were still slightly damp which didn't seem to be a problem - until she modestly tried to cross her legs. There was a squeak of resistance as the moist skin rubbed against the cold hard plastic, which in turn caused a slight vibration to touch her lower lips. Anna gasped and instinctively reached down to touch them protectively. She rubbed at the sensitive skin of her pussy to make sure there were no sore spots but instead found a lovely pleasurable spot. She rubbed it once or twice - purely to make sure it wasn't injured, of course.

Before she could go any further she heard footsteps enter the room accompanied by voices. Remembering those spy films where they looked underneath the cubicle for a suspect's feet, Anna panicked and lifted her feet up off the ground. She spread her legs so that her feet were touching both walls of the cubicle and leaned back against the wall for balance. She clasped her hands over her pussy and tried to remain calm.

"...do you think about this nude girl stuff?" one of the voices said.

"It can't be true. The teachers wouldn't allow it." another voice said.

The footsteps stopped by the urinal. After a moment or so the sound of running water hitting metal could be heard, followed shortly by a second stream.

"A lot of people saw it. They even say there was a second girl who joined her afterwards."

"They're just trolling everyone. Stuff like that just doesn't happen in real life."

Anna - slowly and uncontrollably - began to finger herself. 'No boys,' she thought 'Sometimes it does.'

"Yeah, well... if Tracy in math class wants to try it, I'm not going to discourage her."

"Her tits are kind of small."

"They look alright to me..."

The sounds of water stopped. The footsteps moved towards the bathroom exit taking the two unsuspecting boys away from the mostly naked masturbating girl hiding in the cubicle.

Anna lowered her feet to the ground, but her fingers didn't stop. She began to move them up and down furiously, aching to orgasm before the locker room emptied out. For some reason the thought of being discovered like this made it seem so much more exciting. A few moments later she came. Her post-orgasm clarity allowed her to control her breathing and keep it relatively quiet, but she couldn't stop her toes curling up on the hard tiled floor. Once it was over she eased back against the wall and allowed herself to enjoy the moment.

She was awoken by the sound of the phone buzzing within the shirt pocket. She must have fallen asleep! Her thighs sticky with her own cum, she got to her feet and grabbed the phone. She flipped it open. The message read:

"Library. Romeo's got your panties in his face."

Anna strained her ears. There was utter silence from the changing room now. She grabbed some toilet paper and quickly cleaned herself up. Once that was done, she eyed up the shirt. It was still wet, maybe a little bit dryer than before, but the library meant walking the school hallways and she was damned if she was going to do that wearing just a bra! Still, the idea of wearing it wet was not appealing...

Without stopping to think if it was a good idea, she grabbed her things and unlocked the cubicle door. She swung it open. There was nobody there. Breathing a sigh of relief, she placed the bra and phone on the counter like before and quickly worked on drying the lower half of the shirt. It took a lot less time than before. She reasoned that it had spent some time air-drying. Satisfied with it, she slipped her arms into the sleeves and quickly buttoned it up. It felt a little bit tight, for some reason. When she looked at herself in the mirror, she gasped; the shirt had shrunk! Usually the shirt reached down to her mid-buttocks but now it hung up near her belly button. It must have been some combination of the pool's chlorine and drying it with a hand dryer. It left her a great deal more exposed. She couldn't step out into the hallways like this and not be noticed.

She grabbed the phone and bra, and went to investigate the men's changing rooms. Maybe somebody had left something behind - a pair of shorts, maybe, or even a long t-shirt. She nearly leapt for joy when she found it: a towel. A decently sized black towel! She picked it up, and immediately dropped it in revulsion. It was wet and smelt kind of sweaty. She completed a quick circuit of the room but found nothing else that could be used. With a sigh, she picked up the towel. Beggars can't be choosers...

A few moments later, in the empty hallway, the boy's changing room door opened. Anna's head peaked out to see if anyone was around. They were not. She stepped out into the hallway wearing a short white blouse and a black towel wrapped around her waist that looked like a skirt... from a distance. The students in her grade would currently be in a study session; a free hour before the final class of the day. That means they could be anywhere in the building. The other grades would still be in class. All she had to do was head to the library and retrieve her panties.

She hesitated, and looked down at her bare feet. From a distance the towel might pass for a skirt, but with her feet bare the illusion was easily broken. She could head to her locker and retrieve the footwear she'd abandoned there earlier today. However, if she remained barefoot then she'd have a semi-logical reason for wearing the towel without footwear. If anyone asked she could tell them she'd just been swimming but hadn't had time to change out of her costume. Although why she'd be wandering around the school in her swimsuit bottoms and a towel would be another question...

So:
