"Yoga"

“How about a little yoga?” Mr Carter said with a predatory smile.

Yoga didn't sound so bad, but she didn't trust his expression in the slightest. Her stomach turned over and over inside her. She was so ashamed that she felt sick, her only wish in the world to be out of this situation and properly dressed once again. She'd never be late again, she'd never put a toe out of line... but it was too late for that. She'd already messed up, and now the whole school was leering at her bare body.

Every few moments she shuddered anew as her mind focused on a new part of her body that was now on full display. Her big tits, hidden for so long within modest clothes, now swaying and bouncing in front of everyone. The cool air made her brown nipples pert and puffy, and she was sure that some of the crowd were certain that she was secretly getting off on this humiliation as a result. Then she thought of her plump round ass, now marked across each perfect buttock with smarting red marks from the ruler. That was evidently the favourite asset of so many in the room, the crowd audibly approving every time her big rear jiggled.

Worst of all though, inevitably, was her barely-covered pussy. That was something special to her, something that was supposed to be completely private – and here it was on display for her classmates and teachers to stare at, taking in the details that her g-string completely failed to conceal.

“Let's start with an easy one. Balance on one leg and raise your arms above your head.”

Amira obeyed without complaint, raising her left foot off the ground. She wobbled clumsily, her muscles still aching from the jumping jacks, and the movement set her tits swaying as she tried to recover her balance. She could see the crowd following the motion, gazing in fascination as her heavy tits wobbled to and fro as she tried to stay upright, and her cheeks flushed with humiliation as she realised again that she'd been reduced to simple sexual entertainment. She was just something for them to leer at, and the constant camera flashes and recording smartphones ensured that they'd be enjoying her body for much longer than just today.

Her burning thigh muscles spasmed, and she dropped her left foot to steady herself – and at once felt the sharp smack of the ruler on her abundant rump. There were tears in her eyes, but she wasn't sure if they were from the pain or the shame as she raised her foot again, wobbling desperately.

“Keep that foot in the air!” Mr Carter snapped at her, before turning to the crowd. “Now, missy here is a perfect demonstration of what happens when you can't follow the rules. Our school has a clear dress code, but day after day I see girls flagrantly ignoring that code. They pin up their skirts to be shorter, they tie back their shirts to show off their stomachs, and they leave buttons unfastened to expose outrageous amounts of cleavage. It's not fair on their peers. It's immodest, disobedient, and it's... distracting.” He trailed off, and she could sense his gaze travelling over her developed body.

“But this- this is just too far. Missy here thought that this outfit was acceptable attire for school. No doubt she thought that it was going to earn her some male attention.”

Amira jumped as she felt the cool touch of the ruler again, but this time it was a gentle trace over her smooth stomach.

“Her midriff, completely exposed. Completely unacceptable.” The ruler moved up, and she shuddered as it reached her breasts, indicating them to the audience like a teacher at a whiteboard. “Her breasts, again completely exposed. Cleavage is one thing, but missy here thought that it was acceptable to put everything on display.”

The ruler was suddenly at her left nipple, prodding it roughly before carefully tracing her puffy brown areola.

“Take a closer look. Is this acceptable dress for a student?”

The crowd jeered, pushing nearer and nearer as they captured every inch of her body on video, in pictures and in their memories. Amira had always been a little self-conscious of her rather large, dark brown nipples, taking care whenever she could to make sure they were never visible through her clothes, but now they were being poked and examined as everyone watched. She could even see other teachers in the crowd, watching with approval as her body was scrutinised.

She shied away instinctively from the crowd, but the moment her foot touched the ground again Mr Carter gave her a sharp smack with the ruler – this time right on her breast. Her big butt was one thing, its plumpness providing plenty of cushioning, but her breasts were far more sensitive and she couldn't help but let out a little whimper as she tried to swallow back tears.

“See, even now she's disobedient, trying to avoid her punishment. She doesn't seem to realise that she could have avoided all this she'd just followed the rules in the first place and didn't dress like a little-” he caught himself, before grinning. “Well, you all know what I was going to say.”

“I didn't- I didn't mean to dress like this,” Amira finally managed to say, “It was an accident!”

The crowd laughed as Mr Carter gave them a knowing look.

“Ahh, she accidentally dressed to show off all her assets. No doubt the distraction it would cause her classmates and teachers never even crossed her mind.” The ruler slid back down, all the way to where her g-string completely failed to conceal the dark bush over her mound. “Surely, she put on a g-string this morning and thought that it was going to be perfectly modest – despite that even a glance in the mirror would reveal... well, you don't need me to describe what's right in front of your eyes.” He traced the thin string that served as the waistband of the g-string carefully, before hooking under it with the ruler.

“Do you believe her?” he asked the crowd theatrically, and was met with the expected torrent of negatives.

“No way! She dressed that way on purpose,” a boy shouted.

“She's a slut. She's just stopped trying to hide it,” a girl from Amira's class observed snidely, “I bet she's getting off on all of this.”

“Nobody wears a g-string unless they're trying to show off,” said one of the teachers, shaking his head in amusement.

Amira moaned.

“Y-you don't understand. I didn't mean to dress like this. It wasn't on purpose!”

She was cut off abruptly though as Mr Carter pulled the ruler upwards. Still hooked into her g-string it tugged it upwards, and she let out a little gasp as the limited fabric over her crotch was pulled up between her delicate brown lips, exposing even more of her plump pussy to the onlookers. She flushed in mortified shame, even as the crowd pushed and shoved for a chance to get a better look.

“You know, I think this g-string is completely useless,” Mr Carter said, “It really doesn't cover anything. How about we just... take it off?”

“N-no! Please!” Amira whimpered, “Please let me keep it on, it's all I have left...” she looked up at Mr Carter helplessly, knowing in her heart that no matter what she said, she couldn't affect his decision in the slightest.
