Yes, surprisingly - Daisy volunteers

"Oh!" Miss Bramski said, a little surprised. "Oh, we do have a volunteer."

Mary looked up, equally surprised, to find her friend Daisy with one hand in the air. Her other hand was already on the third shirt button down. Once the teacher gave her approval, Daisy applied both hands to the task.

"I figured if all my friends are going to be naked," Daisy said as she stood and un-tucked the now open shirt. "Then I don't want to be the odd one out."

She pushed the shirt down her shoulders and threw it in a heap onto her desk. She had not been wearing a bra. The other girls in the class were encouraging her to carry on, no doubt feeling sympathy for the two AGS sufferers and wanting to support them (without stripping themselves), while the boys were switching their gazes back and forth like a tennis match, torn between admiring Daisy's uncovered but tiny breasts and Mary's much more ample but hidden assets. Daisy went for the skirt next, unfastening and unzipping it as Mary had done. She threw this unceremoniously on top of the shirt leaving her wearing nothing but black shoes, orange socks and - Mary was surprised to see - a pink thong. At least she assumed it was a thong; from the front it was barely wide enough to cover her pussy lips, and a thin string of material that stretched high over her barely-there hips. Daisy wasted no time in pushing the garment down her thigh, where it got tangled. Grumbling to herself, Daisy indignantly leaned against her desk and lifted one foot out of it, and then yanked it down and off the other leg. She had a neatly trimmed landing strip of black pubic hair.

A round of applause echoed around the classroom as Daisy hugged her clothing close to her body and carried it to the front of the class. She dumped it on the desk and, without bothering to cover herself, stood beside Mary and threw an arm around her shoulder. Mary gave a yelp of surprise at the unexpected physical contact. Miss Bramski began to fold up Daisy's clothing.

"Any more volunteers?" she asked. There were none. "Okay then, we'll bring them back out now. Mary, Daisy; since neither of you have AGS I would like to charge you with their safety and dignity. They will be susceptible to any improper suggestions so I would like the pair of you to work together and to keep them safe."

"No worries." Daisy said cheerfully. Mary mumbled agreement. Miss Bramski moved to the the storage room door and gestured for the girls inside that they could come out now. Jenny came first with Emma huddling behind, the latter covering herself as best she could. The two girls moved to stand alongside Daisy and Mary.

"Okay," Miss Bramski said. "So I've been explaining to the class that National Nude School Day is a lottery based system; you four girls have been chosen to participate. Jenny, Emma; thank you kindly for attending school wearing the proper attire. Mary and Daisy were confused at first but as you can see we've cleared that up now. If you girls would like to take your seats we can begin the day's lesson."

The girls began to move towards their vacant seats which, for Mary, was immediately causing issues. Her enormous breasts, no longer constrained by her heavy-duty bra, jiggled and wobbled with every step. She pressed her arm against her nipples as hard as she could but they kept trying to spill out over the top. Without even thinking about it she moved her other hand up to grab a tit. It had reached her stomach before she realised what she'd just done, and she quickly moved it back to her crotch. She'd just flashed her bare pussy at the room! Groaning with embarrassment, she finally reached her seat and sat down.

SLAP!

Mary sucked air through her teeth while every other girl groaned in sympathy. She let out an 'aah' as the pain radiated through her breasts. She hadn't accounted for them when sitting down and had just slapped them against the table.

"Are you okay, Mary?" Miss Bramski asked, concerned.

"Yeah." Mary croaked. "Just need a minute." Then, realising everyone was looking at her, added "Please carry on the lesson. I'll be fine."

Miss Bramski nodded, and turned to write the subject of today's lesson on the whiteboard. Mary moved backwards in the chair and leaned forward as much as she could so that her chin and neck were resting against the table. With her breasts now out of sight she gently began to massage the ache out of them. Wordlessly Daisy reached over and began rubbing her back supportively .

As the ache subsided, Mary became gradually aware of the other sensations of being nude in public. She'd never noticed how rough the plastic of the school seats were, for example, until it was rubbing against her bare behind. The metal frame of the table was cold against her chest too. In fact the whole room as a bit chilly, now that she thought about it; the school air conditioning, previously weak and unnoticeable, was suddenly inching it's way across every bare inch of her skin.

Unable to focus on the lesson, Mary turned her neck to look at the others. Daisy gave her a smile; her free hand was resting against her thigh, and the girl still made no attempt to cover up. Mary made a mental note to ask about that. Beside her Emma sat with her arm covering her breasts while her other hand nervously flipped her pen around on the tabletop. From this angle Mary could just about see the girl's dark triangle of pubic hair, although she wasn't keen to look too closely. God, AGS? As embarrassing as the situation was she still felt sorry for her friend. That sort of thing could ruin your life.

Jenny sat in the seat one table down, and like Daisy seemed unconcerned about her own nudity. There was something more sensual about her, though. Daisy was boy-ish, but Jenny had a proper woman's body with good-sized breasts and a tan. She made nudity seem sexier which made Mary feel jealous. She was just so fat and clumsy, while Jenny was...

...was masturbating.

Mary blinked, and sat upright. In her surprise she made no move to cover herself. She leaned back and tried to look past Daisy and Emma to confirm, from another angle, what she'd just seen. From this angle she could see the boy who sat behind Jenny - a skin-headed boy who Mary had often seen smoking behind the bike sheds - leaning forward and saying something to her before sitting back down and sharing a chuckle with the boy sitting next to him. Clearly the boy was making use of the girl's AGS to humiliate her further!

"Shit." Daisy whispered. She'd seen it too, drawn by Mary's stare. "What do we do?"

"We should tell Miss Bramski." Mary whispered back.

"It might embarrass Jenny though if we bring it to everyone's attention! Maybe one of us should go and talk to her?"

Or we can just leave her. Mary thought darkly. Skinny cow doesn't even have the decency to be embarrassed by her nudity; maybe an orgasm will humiliate her a little.

Mary was a little bit shocked to find herself thinking like that. Jenny was a good friend of hers.
