Katerina's Classroom Demonstration

[NS2000]

Sorry for the delay, everyone. Here is Part 5:

—————————-

From the moment the bra was unclasped, it was clear that her breasts had lost support, for the full cleavage Katerina had demonstrated earlier dropped down her chest.

Peeling the bra away from her breasts was, candidly, among the most difficult things Katerina had done in her life, and as she tossed the bra to the floor alongside the remainder of her clothing, she felt intense shame and embarassment as all eyes in the room burrowed into her chest and took in the sight.

What they saw was two medium-sized breasts, tipped by half dollar-sized reddish-brown areolas and small, circular nipples. Rather than an lusciously firm pair of breasts, Katerina's hung down somewhat on her chest with nipples pointed slightly downwards. The areola themselves, though a proportionate size, were irregular in shape and featured a rough, crinkled skin, as opposed to a smoother, more clearly circular size. Her breasts were also uneven in size, with the right being noticeably larger than her left.

Katerina, who had always worn supportive bras and swimsuit tops wherever she went, could not bear to raie her eyes and see the class taking in her breasts.

"Thank you, Ms. Katerina," Ms. Weatherby said. "All right class, now that you're having a chance to examine Ms. Katerina's uncovered breasts, what are your thoughts? Does anyone care to share?"

Blake's eyes looked like they were about to bulge out of their sockets--never in a million years did he expect to be able to see, so close and for so long, the uncovered chest of his sister's best friend--someone he had ogled many times over the years. He could barely contain his excitement at what he was seeing. Instinctively, he reached down to pick up his camera to take a photo.

"Wait!," Katerina cried out. "He can't take my photo, can he?" she asked with alarm.

"Actually, he is well within his rights to do exactly that--all of the students here are," Ms. Weatherby corrected Katerina. "Your agreement with the court stipulates this, as did the permission slips signed by all of today's students. This is an educational lesson, and we want our students to be able to reference and recall what they have learned here today. Think of it as simply no more than taking notes."

Katerina had completely missed that part. Photos? Of her naked body? On the phones of a bunch of hormonal 9th graders? It was insane! Taking notes? She imagined every boy--and maybe some of the girls--would be getting off to her photos this evening, and probably for weeks and months to come. And surely the photos would make their way beyond the students in this class!

"But, Ms. Weatherby, as soon as they leave this room--if not before--photos of me will be spread everywhere. That cannot be part of today's arrangements, can it?"

"That is correct," the teacher responded. "Your photos actually CAN'T be shared outside this classroom. The photos the students take are for themselves and their classmates only - sharing beyond that is strictly forbidden, and any student caught breaking that rule will face the stiffest of penalties. In all of my years teaching this lesson, such a thing has never happened to my knowledge."

"To your knowledge," thought Katerina. "Right." She wondered how the school could police such a thing, and decided they probably couldn't. Still, she could only hope that the threat of sever punishment was enough to deter the students from abusing the photos they were taking.

Augh, Katerina thought...what a complete nightmare.

Meanwhile, while this was playing out, several other students had gotten their phones out and started taking pictures of the now-topless Katerina. Katerina noticed this, and instinctively went to cover her boobs.

"Ms. Katerina, please drop your arms immediately," the teacher warned her. Katerina, aware of her absent-minded slip, immediately dropped her arms back to her sides.

"No student may be deprived of a complete examination of your body as he or she wishes," Ms. Weatherby reminded her. "Please do not let it happen again."

Katerina could only slightly nod in resigned submission.

"Right then," said Ms. Weatherby, "As I was saying, with Katerina's breasts now fully exposed, I want to the students to share their thoughts. I am going to call on a few of you to get the conversation started. Daniel--" and here she pointed to the dark haired boy who had spoken up previously "--what are your thoughts on Katerina's breasts?"

"Well, uh," Daniel stammered a bit, interrupted as he was from taking pictures of Katerina's bare chest, and trying to compose himself. "They're nice, I guess. They're a nice size and all."

Miss Weatherby sensed there was more, so she prodded him a bit. "Anything else, Daniel?"

"Um, well," he began, clearly uncomfortable, "they could maybe be a little firmer. I thought all young adults like Katerina had really firm boobs."

"That's actually a misunderstanding," the teacher corrected him, but she was immediately cut off.

The blonde haired girl who had commented on Katerina's skinny legs piped up, "I think they look ok, but they're different sizes, which looks a little strange. And why do her areola look like that? Aren't they supposed to be like round and smooth?"

"Her areola look funny," another boy said, a chorus of students chiming in now, as Katerina's face grew bright red and she hung her head down in shame and embarassment, daring not to meet the student's eye contact.

"Now, now, students," chided Ms. Weatherby, working to get the class under control. "Let's keep our comments productive, please. Criticisms and observations are OK, but let's not try to be insulting."

Already, some students were comparing the photos they had been taking, and looking up a Katerina's bare chest to match what they were seeing on their screens. Henry raised his hand. "Ms. Katerina, have your boobs always looked like this?"

Ms. Weatherby looked over at Katerina--clearly the question was in bounds, so Katerina began t formulate an answer.

"I...I mean, sort of?" she said. "They...I guess, they...used to be a little firmer than they are now. But I am not really sure what you mean."

In truth, she had always been a bit embarassed by her boobs, and they never had the fullness and firmness one tends to expect from the breasts of younger women. It was just something she had been born with, she supposed, and something she had worked hard to hide. Except now her secret was completely open.

"But how old are you?" Henry pressed. "Like, you aren't that old, right? Shouldn't they be firmer?"

"You are asking good questions," Ms. Weatherby interjected. "But remember what we talked about, class. Everyone's bodies are different. None of us look the same, or are society's idea of perfect. You all suspected form the time Katerina first took off her top that perhaps her breasts were not entirely firm or full, and now we have seen that's the case. For a young, thin woman, her breasts do sag somewhat, and her areola do indeed look like those of an older woman. Are these bad things? Again, it depends on what you find attractive."

"Can we come up for a closer look, Ms. Weatherby?" one of the boys asked.

"I suppose," she responded, "No touching, remember, but please do feel free to bring your cameras and take any photos you wish. Ms. Katerina, kindly place your arms behind your back so that your breasts are thrust out, and allow the students to closely examine them."

Katerina was beyond mortiifed at this point, and could only hope to sink into a puddle right there on the floor. She could not conceive of anything more embarassing than this. Still, reluctantly, she did as asked, and clasped her hands behind her back while the students lined up to closely look at her boobs.

One by one they walked by, their eyes merely inches from her nipples and areola, carefully examining every inch, contour and mark of her breasts. They examined her tits more closely than perhaps any of her boyfriends ever had, she thought. All of them, one by one, took photos. Several of them zoomed in closely just on her nipples, and took photos that revealed in excruciating vividness every detail of her nipples and areola.

One girl asked, "What are those faint lines there, along the top of your right breast?," while snapping photos.

"Um," Katerina stammered, "I...I think those are stretch marks you're seeing?"

"Yes," Miss Weatherby stated, "When a woman's breasts grow or begin to sag on her chest, they may leave markings on the skin that we refer to as stretch marks. They are common in women who have born a child, or who have lost a lot of weight. Sometimes though, as is the case with Katerina, you might see them on younger women."

The girl nodded, looked a bit longer and snapped a couple more pictures, and moved on.

Another boy, this one with sandy brown hair was next.

"Can Ms. Katerina turn to the side," he asked.

"Of course," Ms. Weatherby said. "Ms. Katerina, please turn to the side so that Andrew can see how your breasts look in side profile."

Katerina siged audibly and did as asked, turning to her left.

Andrew stared at her from this angle for a moment, and continued taking pictures. Ms. Weatherby noticed, and prodded him for some thoughts. "What do you think, Andrew?"

"I think her boobs are cool," he ssaid, to some gentle laughs from the other students. "But maybe a little weird the way they look from the side of her chest--I can kind of see how they droop a little bit more from this angle."

"Right," Ms. Weatherby said. "Their form is more pronounced when viewing her breasts from this angle. What you are probably noticing is her side-boob, which is where her breast tissue attaches to her chest. In girls with less-firm boobs like Katerina here, the side-boob is more pronounced since the breast is hanging downwards somewhat. Though if you'll note, class, even from this angle Miss Katerina's nipples are still pointed mostly forwards, and not downwards--though that might change as she ages. Go ahead and take a close up of her breast here, Andrew, so you can remember what it looks like from this angle."

Andrew obliged, and Ms. Weatherby asked the mortified girl to turn back around so she could once again face the students head-on, and the line continued.

The worst moment for Katerina was Blake. He walked up to her with a mischievous grin, and planted his eyes inches from her chest, watching her breasts heaving with each breath Katerina took, and began taking a series of pictures zoomed in on ever inch of her exposed chest.

"Hey, Kat," he said while zoomed in on her right nipple, intentionally referring to her informal name to embarrass her further, "What IS up with your areola, huh? Why do they look all weird?"

Katerina wanted to burst into tears - her privacy, her self-image...all of it was being destroyed, and the fact that her best friend's younger brother was staring at and photographing her naked chest and asking such intensel inappropriate and personal questions was almost more than she could bear.

She inhaled deeply before responding.

"They're not THAT weird, I don't think Blake. They're just areolas."

"Yeah," Blake said, continuing to stare intently and snap pictures, "but they're, like, all odd shaped and the skin is really crinkly. Like,I don't want to be rude or anything, but I HAVE seen other girls' nipples before. And it's just that if you'd asked me before today what I thought your boobs might look like, I don't think I would have guessed this."

Seriously??, Katerina thought. "I don't know what to say, Blake," she said with a defeated tone. "It's just how they look, ok? Can you just finish whatever you're doing please?" Her self-confience in herself was evaporating in the face of these withering comments from Blake and others. She didn't think things could get worse.

"Do you like them?" he bluntly asked.

"Not really," she answered honestly. In fact, she hated them. It was one of the parts of her body she hated the most. But she had never confided this to anyone, let alone a room full of strangers like this.

Turning to Ms. Weatherby, Blake asked a question. "I know we cant touch her boobs, but could we ask her to lift her breasts up and drop them to her chest, so we can see how they move when they aren't encumbered by a bra?"

Ms. Weatherby thought for a moment. "I don't see why not. Katerina, could you please do as Blake asks?"

She absolutely thought she would die. How much indignity could she possibly stand? Looking plaintively at Ms. Weatherby and finding no symnpathic response, Katerina proceeded to do as she was asked.

Blake couldn't believe his luck. He quickly switched his camera to video mode so he could fully capture the scene playing out before him.

Gripping each nipple between her thumb and middle finger, Katerina lifted each breast off of her chest, pulling her nipples towards her chin, before releasing them. The breasts bounced down onto her chest with a faint thwacking sound, and proceeded to jiggle on her chest for several moments before resettling.

Blake thought he might just die right there, and was excited to watch that scene--repeatedly, in slow motion--once he got home later today.

The class was transfixed. "Wow, I guess that's why you need to run in a sports bra, huh?" Andrew asked her, to which Katerina didn't respond.

Eventually, to Katerina's relief, Blake moved on. A girl with shorter, brown hair who hadn't said anything to this point in the class waslked up, looking intently at Katerina's chest.

"What do you think?," Ms. Weatherby asked her.

"I think they look kind of nice," the girl replied, snapping a couple of photos. "I dunno...they're boobs. I wouldn't say they're amazing or anything, but I think they are nice."

"Do you think Katerina's sexual partners find her boobs attractive?," Ms. Weatherby continued.

"I guess so," the girl replied, clearly somewhat uncomfortable with the question. "They're a good size and I think kind of cute. And I don't think her areolas are that weird, like Blake did," she said.

Although the girl was saying nice things about her boobs, Katerina just wanted this fixation with her chest to end. Having a bunch of young students ogling her so closely was exceedingly uncomfortable.

Daniel, the dark haired boy who had asked Katerina the questions about her butt earlier, then raised his hand--he was next in line.

"Ms. Weatherby, Ms. Katerina said earlier that her boyfriend enjoyed gripping her butt when she was on top of him having sex. It caused me to wonder what view her boyfriend had of her breasts while they would have sex - based on what she just shared with us, I have to imagine they jiggled around quite a bit. I wonder, could Miss Katerina demonstrate for us what her breasts look like while she is riding someone, so we can see it firsthand? I am sure there are many students here who'd like to see what a girl's breasts look like while she's having sex like that."

Holy christ, Katerina thought, surely this is an unreasonable request? Couldn't they just go to Pornhub or something and watch a video if they wanted to see this? Surely they didn't need her to demonstrate it?

"Hmm," Miss Weatherby said as she thought things through. "So long as you do not touch Ms. Katerina and take only pictures or videos, I guess I don't see the harm in it. It is important after all for everyone to gain the full benefit of a live model here to demonstrate this for us. Katerina, could you kindly climb onto the table here and demonstrate for us what it looks like when your boyfriend is penetrating your vagina while you grind on top of him?"

Katerina thought her heart would simply ecxplode - surely this was well beyond anything that was reasonable. She finally decided to protest.

"Miss Weatherby, please," she began, "surely there are other ways that your students can learn this information? What you are asking is so intensely private, surely you cannot expect me to mime a sex act in front of them?"

Ms. Weatherbvy was nonplussed. "Surely I do, Ms. Katerina. While I appreciate your presence here this morning, you must understand that you have no privacy, at least in this classroom with these students. You gave that up when you agreed to these arrangements yesterday. Thus, I am going to ask--only once more: Please demonstrate for these students what your body looks like when you're riding your boyfriend." As if to emphasize the point, the teacher patted the table on which she was asking Katerina to climb.

Seeing no hope of escape, and nothing to be gained by prolonging this, Katerina slowly climbed onto the table. She remained thankful that she was still wearing panties--for now.

"Please make sure everyone has a good view of her, particulary of her chest," Miss Weatherby said. All of the students crowded around the table, with their phones and cameras out, ready to record the show.

"Remember," the teacher said, "Daniel's request was to see what Katerina's breasts looks like when she is in the throes of passion with her partner. Miss Katerina, you may commence."

She wished she would die, and she felt the welling of tears around her eyes. Still, she swallowed hard and committed to getting through this as quickly as possible.

She climbed onto the table, her boobs swaying slightly as she did so--she was thankful for her panties at the moment, because otherwise the students would have really had a show. She tried to ignore all of the teenagers filming her body as she scooted around a bit awkwardly so that she was on her knees facing the class, then spread her knees apart as if her boyfriend was laying beneath her. Then--in what was the most undignified thing she could possibly think of--she leaned forward and planted her hands on the front of the table. With her breasts dangling beneath her, she slowly began miming the act of riding her boyfriend, gently thrusting her hips back and forth.As she did so, her breasts began swaying forwards and backwards on her chest.

As she continued to thrust her hips, her breasts jiggled and were thrown around even more on her chest, to the point where they started slapping into her chest with an audible thwapping sound.

The students did not make a sound as they watched and filmed Katerina's demonstration. Suddenly, a boy who had been standing towards the front blurted out, "What's going on with her nipples?"

That caused every student's eyes to fixate intensely upon Katerina's nipples, which had perked up and were standing fully erect at the ends of her breasts.

Oh my god, Katerina thought, my body is betraying me and getting turned on by this. The act of thrusting her hips about and causing her dangling breasts to jiggle around was causing her to become aroused.

"That," Miss Weatherby said, "is what a woman's nipples look like when she is sexually aroused. Remember, we talked about this. I would surmise that Miss Katerina is imagining her boyfriend underneath her right now, and the thought of having sex with him is causing her body to become aroused and, thus, her nipples to become erect. This is entirely normal and very common. Oftentimes, a woman's sexual partners will take advantage of erect nipples to gently pull, pinch and twist them, as many women find that stimulating."

All the while, Katerina continued dry-humping the table, her dangling breasts with erect nipples flailing about on her chest. FInally, Ms. Weatherby called an end to the proceedings.

"Alright, I think that's enough," she said. "Miss Katerina, you may get down."

Katerina, now wholly embarrassed yet grateful to be done with this particular demonstration, quickly climbed off the table and resumed standing, wearing only her panties, in front of the students, many of whom had just filmed the entire episode.

"OK class," Miss Weatherby said, "So everyone has now had a chance to closely inspect Miss Katerina's breasts. We've discussed their size, shape and form, why her breasts, nipples and areola look the way that they do, and have seen how her sexual partners see her breasts when she is having intercourse with them. We have also had the fortunate opportunity to observe her nipples becoming erect as she becomes sexually aroused. Does anyone have any further questions about Miss Katerina's breasts before we move on?"

One girl in the back raised his hand.

"Yes, Erin?" Miss Weatherby asked.

"Yeah, I wondered, Miss Katerina, whether you have to try on particular bras and stuff to make your boobs look good? I am thinking that when you had your shirt on and even when you were just in your bra, we call couldn't really tell whether your breasts drooped or sagged at all. Which, like, is probably intentional, right? So what do you look for?"

"A very good question, and probably one a lot of girls here have. What say you, Miss Katerina?"

Katerina swallowed hard again before answering.

"Well, yeah, my, uh, breasts do require a bit more support. They aren't overly big as you can see so they aren't like some larger girls who require special bras and bikini tops and such. But, when I am buying new bras, or a new bikini, I do make sure that when I try them on I see how my boobs look from all angles, and do they look firm and supported--or do they, like, maybe hang down a bit. It's not just so they look better, though...walking around all day without properly supported boobs doesn't feel very good after awhile, so a properly sized and fitted bra helps keep that from happening."

"A very helpful answer, Miss Katerina. OK then, I think we are at a point when we can proceed with our lesson. Students, I would like for you all to return to your seats for now."

The students dutifully did so, as Ms. Weatherby turned her attention to the nearly nude girl beside her. "And Miss Katerina, please proceed with removing your panties so that we may inspect and discuss your vagina and anus."

Katerina momentarily froze. This was it, she thought. The moment, above all else, that she had been dreading. She waited while the students returned to their desks. Visions of all of the hours she'd spent at Stacey's house with Blake hanging around, and knowing that he was about to gain full view of her most private region--it sickened her. It was horrifying. There were no words for what Katerina was feeling at that moment.

But she also knew, as that voice in her head continued to tell her, that there was no escape from this. This was the punishment she had chosen for herself, and nothing could be done.

Quivering a bit, she inhaled deeply, held her breath, then slipped her thumbs under the waistband of her white panties--her last remaining bit of modesty--and slowly begain gliding them down her hips. Meanwhile, Blake and his classmates all had their phones pointed directly at Katerina's crotch. They didn't want to miss a thing.

[ely]

great, keep it up like this. If they can serve as suggestions, remember that you have not specified whether the door is locked, whether others may enter the room accidentally, whether there will be a snack break, whether the room has windows and whether it is outside It is possible to see the interior of the classroom etc. I find the possibility of taking pictures without any prohibition a bit wrong ...so I expect this to play a big part in the storyline.

[Executionus]

This really is a fantastic series so far with the classroom dissecting inch by inch Katerina's body and its every possible use and action.

[miss.tery]

omg!! please post the rest

[miss.tery]

ASAP

[miss.tery]

still waiting on this one!

[Executionus]

I agree. It's a shame that this story has been paused for so long since it's been quite exceptional so far.

[Tom Collins]

This is a very good story. Well written. I hope you'll continue. I'd be a shame to leave all those students hanging with Katerina's thumbs hooked in the top of her panties.

[computerphoto]

I also hope this will continue soon, can't wait to see how worse her day goes and see what happens in the end.

[NS2000]

Apologies for the lengthy delay in posting this update. Hopefully the next one will be published sooner. Hope you enjoy.

* * * * *

As she reluctantly peeled her panties down her legs, Katerina felt almost as if in a trance--that she was outside of herself, and the woman who was fully naked in front of a classroom of 9th grade students was somebody else. But the feeling of air on her pussy brought her back to reality, and she was suddenly fully conscious of what was happening.

She bent forward to step out of the last bit of clothing that had provided her any modesty, her breasts gently swaying in front of her, then casually cast her panties aside and stood, completely naked, with her arms at her sides facing the students.

She could hear some faint mumblings around the classroom--utterances like "oh wow" and "holy shit," likely from some of the boys who were setting eyes on a vagina for the first time--but maybe some of the girls as well. Katerina felt fully and completely exposed. Many of the students--mostly the boys, Katerina noticed--were busy snapping photos of her now-fully nude body. She saw Blake in particular focusing the lens of his camera while he apparently zoomed in. No doubt, Katerina thought, about what he is snapping a photo of. Sher blushed profusely as her friend's brother, mouth slightly agape, continued to photograph her naked body.

Ms. Weatherby broke the tension in the room by walking over to Katerina and speaking out.

"Thank you, Ms. Katerina," she said. "Class, as you can see, Ms. Katerina is now fully nude--we now see precisely what her body looks like underneath all of her clothing. As you can see, she keeps her public region shaved, as is common for many women these days. Judging from the stubble around her vagina, I am guessing she shaved as recently as this morning, probably in anticipation of this demonstration--is that correct, Ms. Katerina?"

Katerina, thoroughly mortified, nodded gently in affirmation.

"Very good," Ms. Weatherby said. "Now, class, how you are seeing Ms. Katerina now--fully nude--is likely something only a few people have seen. This would include her sexual partners, as well as perhaps her doctor. As we've discussed, except in a few select circumstances, women do not generally parade around completely nude, so how you are seeing Ms. Katarina right now is an exceptional situation, and I do hope you appreciate that.

As we have been doing, I would like to get your thoughts on her body and what you are seeing. Does anyone want to volunteer?"

The class for a moment was silent, and Katerina could hear her own heart racing in her ears. Finally, one of the boys she'd learned was named Daniel raised his hand.

"I think she looks really good naked," he offered. Several other students nodded in agreement.

"And why do you say that, Daniel?" Ms. Weatherby asked.

"Well, um," he stammered a bit, "I like how you can see her pussy very clearly, since she is shaved. It looks really nice. And her hips are really pronounced--you can really get a sense of her hourglass figure now that she isn't wearing any clothing."

"Very good," said Ms. Weatherby. "Anyone else? Yes, Amy?" Ms. Weathewrby pointed to the girl in the front row.

"Yeah, um, Ms. Katerina, what's sticking out between your vagina?"

Katerina blushed profusely at the directness of the question.

"Ah," said Ms. Weatherby, "a very good question. From this angle, what you are seeing there is Ms. Katerina's clitoris--or rather, her clitoral hood. As we have discussed, the clitoris is the main organ of sexual stimulation for women. Touching or rubbing the clitoris is often what brings women to orgasm, though stimulating other areas can work as well.

With regards to Katerina's pubic area, this is where we can notice some of the differences in how women's external reproductive organs present themselves. Some women's clitoral hoods and inner labia are completely covered by their outer labia. Others, like Ms. Katerina here, are more exposed."

In truth, Katerina hated how prominent her inner labia were. She thought it made her pussy look ugly, and she would sneak glances at other women's pussies in the showers at the gym and feel twinges of jealousy at how neat and tidy they looked. It thus made it that much more embarrassing for Katerina that the teacher and students were now so fixated on this most private of parts of her.

Kevin raised his hand. "Ms. Weatherby, you said we were seeing Ms. Katerina's clitoral hood--does that mean the clitoris is underneath it?"

"Correct Kevin," the teacher responded. "As we have discussed in class, unless aroused, a woman's clitoris is covered by the clitoral hood. This prevents unwanted stimulation of the clitoris--can you imagine if every step you took throughout the day was stimulating your primary sexual organ? It would make daily life quite difficult."

This caused several of the students to chuckle a bit. Meanwhile, all eyes remained firmly fixated on Katerina's pussy.

"Can we, uh, see her clitoris?" Kevin asked.

"Yes, of course," Ms. Weatherby responded. "Ms. Katerina, would you kindly raise your clitoral hood and expose your clitoris to the students?"

No matter how long she was here, Katerina would never adjust to the bluntness and directness of these questions. They were so completely unnatural for anyone to be asked these things. She nearly imperceptibly winced at the question. Then, using her left thumb and middle finger to spread open her outer labia, she used her right index finger to gently push up her clitoral hood and expose her small, pink flower to the class. Other than her gynecologist, no one other than the half dozen or so guys she had slept with had ever seen this part of her. She flushed red with embarrassment as all of the students craned their necks to get a view. Again, the cameras came out.

One boy who was seated towards the front of the class, made no effort to hide his interest as he craned forward, zoomed in closely on her public region, and took a burst of photos as Katerina stood there, holding her vaginal lips apart.

"It's so tiny," the boy said as he leaned back in his seat. The girls in the class, meanwhile, were silent, no doubt comparing the clitoris of the fully grown adult in front of them to their own, and considering how they measured up.

"Yes," Miss Weatherby said, "in its non-aroused state, the clitoris is a very small organ. Although--" and here the teacher bent down to get a closer view of Katerina's clitoris as the mortified continued to lift her hood, "--it looks like it might be slightly enlogating, likely due to the gentle stimulation that Ms. Katerina is subjecting it to. In other words, we are witnessing the beginning of the arousal of Ms. Katerina's clitoris. This is quite similar to how her clitoris would look if she was preparing for intercourse."

My GOD, Katerina thought to herself. Could this possibly get anymore embarrassing? She was horrified to realize that what the teacher was saying was correct--she could feel herself getting actually turned on by the situation, and had also begun feeling a dampness in between her labia. In spite of everything her rational brain was telling her, her body found what was happening--arousing? Exciting? She could not believe it, and it made her even more embarrassed, if such a thing was even possible.

"OK, that's enough of that for now, Ms. Katerina. You may remove your hands," Ms. Weatherby said, which Katerina was quite grateful for. "Before we proceed further with a more thorough examination of Ms. Katerina's vagina, I would like to have her turn to the side again so that we can all get a fuller perspective of her nude body from that angle."

She was nearly used to this by now, and so turned to her right to give the students a view of her fully naked profile from her left side.

"Note, again, how her left breast looks from this angle and how it slopes slightly downwards on her chest," Miss Weatherby pointed out, "and how you get a better sense of the shape and form of her breasts. Note also the curvature of her buttocks, now fully unclothed, and her upper thighs, down to her feet. Picture, class, how you imagined Ms. Katerina's body would look when she was standing in this pose fully clothed, and how she looks now. It is a good example of what clothing does--and does not--tell us about someone's body."

Here, she paused a moment to let all of the students pour their eyes over Katerina's body as she continued to stand at attention, facing the side.

"Ms. Katerina, would you please turn again to face away from us, and present the students with an uncovered view of your buttocks?"

Katerina sighed and, without protest, did as she was told, exposing her fully nude backside to the class.

"Now class," Miss Weatherby said, "there were some comments earlier about how some of you thought her butt looked rather small and flat against the rest of her body. Now, we are seeing her buttocks fully uncovered. So I want to revisit that question: what do we feel about Ms. Katerina's butt now?"

One girl raised her hand. "I think it actually looks really nice and smooth," she said. "It doesn't look small to me."

A couple of other students nodded in agreement.

A boy raised his hand. "It does look very firm and tight, it's better looking at it straight on. From the side though, I think I'd like it better if it were fuller and rounder."

Another boy spoke up. "I like how you can make out a bit of her vaginal lips at the top of her thighs."

"Good observation," Ms. Weather by said. "Yes, women with exposed inner labia like Katerina will often display them when standing fully nude facing away. Had she a vagina where the outer labia covered everything, it is unlikely you would be seeing the outline of her lips from this angle.

Does anyone else have any other comments about Ms. Katerina's buttocks or backside?"

Katerina turned her head over her left shoulder to look, and saw Blake raise his hand. "Oh god," she thought.

"Yes," he said with a smirk. "I wonder if Ms. Katerina has ever had anal sex, and whether she enjoyed it?"

'A fair question to ask," Ms. Weatherby said. "Well, Ms. Katerina?"

Katerina was silent for a moment, not wanting to divulge this incredibly personal information to her friend's brother--or to the entire class for that matter. Biting her lower lip, she finally responded.

"Yes, once, and no, I didn't enjoy it."

Blake smiled with satisfaction at getting this bit of information from Kat. He also felt his already pronounced erection grow stiffer as his mind pictured Katerina getting rammed from behind.

"This is actually a topic that varies greatly from woman to woman," Ms. Weatherby said. "Someone women find that they can become quite stimulated by having their anus penetrated. Others--such as Ms. Katerina, apparently--do not find the experience as enjoyable. Despite what some may tell you, anal sex can be an entirely safe and enjoyable activity--but make sure that you have the consent of your partner before engaging in its not everyone necessarily enjoys it."

Ms. Weather by turned to Katerina: “Can you explain to the class why you didn’t enjoy anal sex, Katerina?”

Katerina swallowed hard at the intrusiveness of the question before responding. “It, um…well, it made me feel very full, and not in a good way. Also I don’t think we used enough lubricant.”

“A very good point,” Ms. Weatherby stated. “Unlike her vagina, Ms. Katerina’s rectum would not have created natural lubricant for her sexual partner to enter her. If she did not use sufficient lubricant, it very well could have been an unpleasant experience.”

Blake raised his hand once more. "Yes, Blake?" the teacher asked.

"Yeah, could Miss Katerina please display her anus to us? Many of us boys have not seen a woman's butthole before."

"Yes, of course," Miss. Weatherby said. "Miss Katerina, kindly spread your butt cheeks apart and display your anus for the class."

She really, truly thought she would simply die of embarrassment. She had not even exposed herself in this way to her boyfriends--quite literally no one had ever gotten the view that Blake and the class were about to get. Inhaling deeply, she reached around with both hands, and spread her cheeks apart in order to present the class with an unencumbered view.

"Can you please bend over slightly to give the students a better view," Miss Weatherby asked Katerina, who was well past the point of expecting any grain of modesty during this demonstration. She proceeded to bend over slightly and further stick her butt out towards the class.

All of the students leaned forwards in their desks to try and get a good view.

Another boy raised his hand. "Ms. Weatherby, may we come up and more closely inspect Ms. Katerina's anus, please?"

"Thank you for asking respectfully," the teacher responded. "Yes, of course. Class, as we did with Ms. Katerina's breasts, please form a line to closely inspect her anus. Remember, no touching, and please do not take long so that everybody has a chance to get a good view."

Katerina could not in her wildest imagination dream up a scenario more embarrassing for her than this one. She watched as an entire classroom full of 9th grade students rose up from their seats--many of the boys with visible erections--and proceeded to line up so that they could closely inspect her exposed butthole. It was beyond horrible, and worse--she had absolutely no recourse but to stand there and take it.

One by one, the students walked up to her and leaned forwards, their eyes mere inches from that most private of places on Katerina's body. Many photos were taken of her crinkled, rose colored hole. She was thankful that she had taken the time to be so thorough in the shower this morning.

One girl, peering closely at her anus, asked "Ms. Weatherby, is it normal for girls to have some hair around their butthole, like Ms. Katerina has?"

"It's entirely normal, yes," said Ms. Weatherby. "That is merely an extension of Ms. Katerina's public hair. However, because--for obvious reasons--it is difficult to shave that area, you see the hair more visibly than what you see around her vagina. Some women choose to get their public area waxed, which removes all of the hair--including that around the anus."

Satisfied, the girl moved on.

Blake was up next, and Katerina was dreading what he would say. She felt, more than watched, his face just inches from her body and--she wears--felt him blow gently on her pussy. She instinctively shuddered at the feeling--which wasn't;t entirely awful.

"Did it hurt?" he suddenly asked.

"What?" Katerina responded.

"When you had anal sex--did it hurt?"

"Um, it, uh," Katerina stammered in answer to this intensely probing question by her friend's brother. “Like I said, I just felt very full. Uncomfortably full. It didn't really hurt so much as it didn't feel very good."

Blake continued looking intently at her little puckered opening, then nodded and stepped away smiling. He did not even attempt to mask the erection that was bulging in his pants by this point.

Miss Weatherby watched as the students continued to file by. Eventually, after everyone had gotten a good, close look and had returned to their seats, Miss Weatherby told Katerina she could release her buttocks, stand up straight and turn back around to face the class.

"Thank you for that, Miss. Katerina," the teacher said. "I would like to move on with our lesson now, Please, could you kindly climb up and sit on the stool?"

Katerina, who could sense where the lesson was headed, quietly pulled the stool forward to the front of the class and climbed onto it, her legs closed together to maintain what modicum of modesty she could.

"Previously," Miss Weatherby began, "we had a view of what Miss Katerina looked like fully naked when looking at her straight ahead. We also had her display her clitoris and her anus for your inspection. I would now like to provide a more thorough examination of her genitalia to give the class a good understanding of the female anatomy.

Given the vagina's location on a woman's body, people are generally limited in what they can see of her, even when she is fully nude. But when sitting or lying down, it presents a much greater opportunity to fully take in their vagina and greater pubic region. With that in mind, Miss Katerina, would you kindly spread open your legs and expose your vagina thoroughly to the class?"

Katerina inhaled sharply. This was it, she thought. Perhaps the singular moment she dreaded the most. The action that had driven her to tears the previous night when contemplating it. Be strong, she told herself. You are almost through this. She took one final deep inhalation of breath, and proceeded to fully open her legs and reveal her most private womanly charms to the 9th grade class.

The only sound in the room was the gentle shuffling of desks and chairs as all of the students--boys and girls alike--leaned forward to take in the view of Katerina's vagina.

Blake, who had quietly maneuvered his desk closer to the front of the class, stared intently at the exposed crotch of his sister's friend, taking in this most private of views.

"Alright class," said Miss Weatherby finally, "what you are seeing now is again something likely very few people in Miss Katerina's life has seen: a close, unencumbered view of her vagina and other reproductive organs."

"I will point some things out to you, and then would like your comments and well. We can see that her outer labia--" and here, Miss Weatherby leaned down and pointed her right index finger at Katerina's outer lips--"are a darker red in color. As a woman becomes sexually aroused, more blood flows into the labia and they take on a darker hue. Most women's labia are naturally a darker color than the skin around her upper thighs and pubic region, but this is more pronounced when a woman is sexually aroused.

Note also her particularly pronounced clitoral hood, which you had seen from another angle. Here, you can get a better sense of how, when a man's penis is penetrating Katerina's vagina, he can rub against her clitoris, giving her the stimulation required for orgasm.

Finally, I want to draw your attention to her especially pronounced inner labia, which protrude quite visibly from between her outer labia. This has already been remarked on, and recall that you could see them just underneath her buttocks when she was standing facing away from you--but here, you can get a good sense of exactly what they look like. Miss Katerina's inner labia, by the way, look very similar to what most women's inner labia look like--the only difference being hers are more exposed.

As we have discussed, whether or not you find exposed inner labia attractive is an issue of personal taste. Some do, whereas others find a more 'cleaner' look attractive."

Ms. Weatherby paused briefly here to allow the students to process what they were seeing.

"Now, does anyone have any comments they would like to share?"

The sandy haired blonde boy raised his hand. "How...uh, how does the guy know where to put his...his..."

And here Ms. Weatherby interjected: "his penis? That's a good question, Andrew, and precisely why we are having this discussion. I can see why you would ask that question, as looking at Ms. Katerina's vagina you can surmise where an opening would be--but since her lips are closed, you cannot see it directly. The opening to Ms. Katerina's vagina will be below her clitoris, and in between where her inner labia come together. Surprisingly, not too far from her butthole. Miss Katerina, could you please spread your lips apart and show the students your vaginal opening?"

Katerina closed her eyes--she would never be used to this obscene level of exposure--then spread her lips apart, exposing the pink, inner view of her vaginal opening and her urethra. Mortifyingly, she found that she was getting rather wet, and felt her womanly lubricant on her fingers as she pulled her lips apart. She could also--must to her extreme embarrassment--feel her clitoris enlarging.

"Thank you," Miss Weatherby said. "Now can you see her opening, Andrew?"

"Yes, he replied, mouth agape. "It looks really pink."

"Correct," Ms. Weatherby said. "All vaginas look this way--once you get past the inner and outer labia, the tissue takes on a bright pink appearance. The opening is, of course, where the man inserts his penis during intercourse. The inside of a vagina is soft and ribbed and, during intercourse, becomes quite moist, providing comfortable and engaging stimulation for the male. When he orgasms, if he is not wearing protection, he ejaculates his semen into Katerina’s vagina and into her cervix, which sits at the back of the vagina. The cervix leads into her womb, which is where contraception can occur if Katerina is fertile. And that, students, is the essence of reproductive sex."

The students did not respond, as they were too busy feasting their eyes on Katerina's exposed vagina in front of them. Blake, in particular, felt as though he might explode into his pants simply by what he was seeing. It was simply incredible.

Finally, another boy raised his hand.

"What's that little hole above her vaginal entrance," he asked.

"That is her urethra," Miss Weatherby responded. "It is how girls urinate. For boys of course, the urethra leads to the head of the penis--and this is what a woman's looks like."

This was of course very familiar to all of the girls in the class, but they were still transfixed by staring at the fully exposed vagina of the full-grown adult in front of them.

"Alright Miss Katerina, you may close your vagina now." Katerina, relieved at thinking the worst was finally over, released her lips and brought her hands back to her sides.

"Now," the teacher continued, "does anyone else have any observations about Miss Katerina's vaginal region? What do you think?"

The girl who made smarmy comments about Katerina's butt and breasts raised her hands. "I don't think her vagina looks very good," she said. "The inner labia look all crinkly and weird."

Whoever that girl was, Katerina thought, she hated her. She could only hope that someday in the future, the girl would find herself in Katerina's position, and would know what it felt like to have such comments made about her body.

"Ok," Miss Weatherby said, “that's a rather crude but fair observation. As I said, not everyone thinks exposed inner labia are an attractive feature."

"Yeah, I am glad my pussy is very neat and doesn't look like this," the girl said.

"Well, thank you for sharing that," Miss Weatherby said, while several of the students surpassed a few giggles.

"All right, any other observations, class? Or shall we wrap things up with Miss Katerina here?"

Katerina began ever so slightly to relax, as she could finally sense of the end of this awful demonstration was in sight. She allowed her mind to briefly wander to views of her scrambling to put her clothes back on and run as quickly as she could out of this infernal place, never to return to it. She felt that she would be forever scarred and shamed by this experience, but was also quick to be done with it.

Her slight feelings of relief were short lived, however, as she heard Blake's voice suddenly speak out.

"Miss Weatherby, why does Miss Katerina's vagina look shiny?"

The teacher bent down to look at Katerina's vagina, still spread open on the stool, and could see that it was indeed glistening, and there were small strands of lubricant between her lips.

"Well," she said, "it would appear that Miss Katerina is sexually aroused at the moment, likely from the experience of exposing herself to everyone in the classroom. This is not uncommon. Look, class," and here she pointed directly at Katerina's vagina, "recall how I said a woman's labia tend to get darker as they are sexually aroused? Look at how Katerina's labia are colored now, as compared to several minutes ago--you can clearly see that they have darkened. Note, also, that her clitoris has begun to emerge from its hood--a signal that her body is aroused and seeking stimulation. But to Blake's point, the glistening that you see is the natural lubricant her body is creating in her vagina because she is sexually aroused. This is Katerina's body's way of preparing itself for sexual intercourse, and a good indication of her level of arousal."

Katerina thought that she would simply evaporate at these words--exposing herself was awful enough, but to have her body betray her in this way-and to have it so publicly seen--was beyond anything she ever thought she could bear. How did anyone get through this, she thought. Meanwhile, she was appalled to discover that she was continuing to get more wet and more turned on as this went on. What was wrong with her? She should not be getting aroused by this. But the reaction of her clit and pussy was telling her otherwise--indeed, she was beginning to crave release.

She wondered where things would go from here--and whether this would finally bring an end to the demonstration, or whether more was in store. She prayed for the latter, but was disturbed by Blake's voice once again speaking up.

"That's interesting, Miss Weatherby," he said. "I think all of us would benefit more from this lesson if we could get a sense of what a female orgasm looks like. Since she is clearly aroused here, could we ask Ms. Katerina to stimulate herself to orgasm and watch her cum in front of us?"

Ms. Weatherby paused to consider this. This was not part of the standard curriculum, and while there was nothing in the guidelines expressly prohibiting it, she did wonder whether what Blake was asking truly fit within the scope of the class.

"I don't know, Blake," she said. "The guidelines do stipulate that there can be no sexual activity as part of this lesson. I am afraid I will need to decline that request."

Katerina felt momentarily overjoyed with relief. Finally, she thought, we have reached the line that would not be crossed. Now please, she thought, allow me to regain my modesty and leave this place!

However, Blake spoke up again.

"Yes, Ms. Weatherby, but the guidelines do state that there can be no sexual activity between the model and us students. It doesn't prohibit the model stimulating herself. And I think all of us would greatly benefit from a live demonstration of Miss Katerina bringing herself to orgasm today. Otherwise, we will be forced to seek this information out on our own."

Miss Weatherby paused again as she thought through the situation. Finally, she said, "You know Blake, you have made a persuasive argument. There is not anything in the guidelines that prohibit a model from stimulating themselves to orgasm, and I do agree that this would be beneficial to everyone."

Katerina felt like her heart was going to stop. Surely she would not be asked to masturbate herself to orgasm in front of these students? Could that possible be within the scope of this lesson??

"Miss Katerina," the teacher said, to Katerina's great chagrin, "please situate yourself on the table here with your legs opened towards the students, and demonstrate for them how you stimulate yourself to orgasm please."

Oh no, oh no, oh no, Katerina could only think. She would never be able to get past this moment in her life again--exposing herself to a bunch of 9th graders was awful enough, but now she was being asked to masturbate to orgasm in front of them? It was the most horrifying thing she could think of. She looked pleadingly at Miss Weatherby, but saw there would be no relenting, as her mind had been made up.

"Please, Miss Katerina, let's proceed with the lesson," the teacher said.

Holding back tears of embarrassment, Katerina stood up from the stool, pushed it aside, then climbed onto the table, well aware of the her swaying breasts and the intimate view of all her private parts that the students were seeing.

She laid back, placed her feet on the edge of the table, and--despite her brain screaming at her not to--proceeded to spread her legs apart and give the students an unfettered view of her open vagina.

She then slowly, reluctantly, brought her finger down and gently touched her clitoris. To her surprise, she felt a jolt of lightning throughout her body. Her clit was at full attention, and she could feel her vagina was sopping wet.

Against everything her rational brain was telling her, Katerina slowly released any semblance of modesty or privacy, and began gently rubbing her clit.
