Relieves the tension... and makes a mistake

Anna touched her exposed pussy, and her fingers came away covered in a small amount of cum. She rubbed it off on her hip.

"I think I need to... deal with a situation before I get dressed." Anna replied to Claire's question.

"I don't blame you." Claire said. "I'd be horny as hell if I did something that daring."

"Speaking of daring..."

It was a day of bad decisions and bold dares. As Anna moved towards the bathroom cubicle she stepped quickly in front of Claire and, before her friend could react, planted a kiss on her lips. Claire pulled back, looking a little startled, as Anna gave her a cheeky wink.

"I kissed a girl and I liked it." Anna sang as she stepped into the cubicle. Using her ass she slammed the door shut behind her, although she did turn and slip the lock into place by hand. Then she sat on the seat and began fingering herself.

"I..." Claire's voice carried over the cubicle door. "I wasn't... I can't..."

Anna let out a loud groan, drowning out whatever Claire had been about to say. She stretched her legs out as far as they would go so that she was barely touching the cubicle door with the tips of her shoes. To her it had always made orgasms seem more intense to be stretching while doing it. Her index and middle finger made hooking and unhooking movements inside her pussy as she gently petted her clitoris, while her other hand reached up and began to caress her breasts. She closed her eyes...

...and imagined herself standing at the front of the classroom once again, this time not just standing and explaining Math problems to the gawking classroom but actively masturbating in front of her peers. She sat on the edge of the teacher's desk, legs stretched out so that they touched the first row of student desks.

"I see," Mr Weathers seemed to be saying. "Could you please explain how you solved the masturbation equation to the rest of the class?"

"My nipples," she said, squeezing one of them "Are variables, since I can only massage one at a time. However neither are important when compared to the solution of CLiT plus Fingers as they can multiply into orgasms if done right."

A student - his face a mystery in Anna's mind eye, which was focused instead on the dozens of students watching her - raised his hand. "Wouldn't two hands work better, then?"

"Oh god yes." Anna breathed. She lowered her free hand over her crotch, where her two fingers were working their magic. She began to massage her knuckles which pressed her fingers in further, which sent a wave of pleasure through her body. She could feel her breasts bouncing with the movement; she lowered one foot to the floor to steady herself. She began to pick up the pace, her fingers no longer curling but instead battering herself with a jackhammer rhythm.

"As you can see," Anna told the classroom "I'm a dirty, slutty little woman who has been Miss Goody-two shoes for too long! I... I... I... may n-never wear... clothes... oh yes... oh god yes..."

Anna opened her eyes and found herself in the cubicle again, her breathing ragged and heavy as an orgasm shook through her body. Her breathing began to steady as the tension left her, and her other foot returned to the ground with a loud clap. She leaned back and relaxed, and her breathing slowly returned to normal.

A few minutes later - and a few strips of toilet roll to clean herself up - Anna stepped out of the cubicle feeling relaxed, red-faced, and renewed. She checked herself out in the mirror both front and back, making sure that all of her cum had been cleaned up.

"Okay Claire," she called out "I'm ready to get dressed now."

But Claire was nowhere to be seen. The mirror reflected only the naked Anna. She pushed at the other two cubicle doors expecting to find resistance - and Claire - behind one of them. They both opened to reveal nothing inside. A quick scan of the rest of the room found it to be completely lacking in both Claire and Claire's backpack.

The school bell rang, indicating that the next class was about to start.

"Oh hell." Anna muttered.

Had it been the kiss? Claire had looked... what, panicky? Shocked? ...horrified? Anna had been on a sexual high and hadn't really given it much thought. Had she freaked her friend out with her joking little kiss? They'd done a lot of dares with one another, but none of them had ever crossed the boundary to anything other than friendship.

Anna was at a loss. Claire was supposed to be in her next class so it seemed the quickest way to get to her clothing, although it would mean yet another lesson spent in the nude. However there was still the risk that Claire had completely freaked out and had gone home which would leave Anna trapped in school without any clothing.

She could play it safe and hide in the bathroom though. Or maybe head to the Principle's Office Lost and Found and throw herself at fate's mercy...
