Modeling for the Class

By: Charles Petersunn



This story is sort of a sequel to Naked at College, but please don't expect it to be of the same genre. I am working on a true sequel to Naked at College and hope to have it loaded the next time (1-2 months from now, which may not mean too much if this isn't the same day that "Modeling for the Class" was loaded). In any case, I do hope you enjoy it!

Marilyn Sanders and Alex Brandon had agreed to serve as models for Dr. Magnus Hirschfeld's class. It was quite an opportunity for the students, and Dr. Hirschfeld was tremendously pleased. There was something about having real, live models that made teaching so much more stimulating, inspirational, and, ultimately, insightful. He was frankly surprised that they were so willing, as many previous attempts to obtain models had been unsuccessful. However, he understood the reluctance. How many persons could you expect to be willing to model for a Human Sexuality class, particularly at such a conservative college? Dr. Hirschfeld couldn't be more grateful for their willingness to help with his instruction. 

It was not, however, something that Marilyn and Alex had actually sought to do. It was true that they were "willing" to serve as models, but one would not actually describe them as "wanting" to serve as models. In fact, if it was really up to them, they wouldn't do it at all.

Marilyn and Alex were undergraduates at Abberville College (both were 19 years old). Abberville had recently implemented The Program in which students volunteer to attend classes naked throughout the day (see "Naked in College, #1"). It was expected that the clothed students would be duly respectful of those who were taking the bold steps to be naked throughout the day. Students who were caught verbally abusing them were subject to becoming future participants within the experimental program of campus nudity.

However, the President of Abberville, in consultation with Professor Billingsley, had decided that it would not be in the best interests of The Program to force students to participate, as if participation within The Program was itself some form of punishment. On the contrary, they wanted students to embrace their participation in The Program, to experience it as a unique opportunity for personal growth and trail blazing leadership.

So, they offered the miscreants a choice. They could either accept suspension for sexual harassment, a blemish on their academic record that could perhaps have quite serious consequences for future employment, or, alternatively, serve as models for Dr. Hirschfeld's course in Human Sexuality (all of the students in his class were at least 18 years old). It was frankly a quite difficult choice. So far, most of the persons caught abusing participants within The Program chose suspension in favor of what might be a most difficult and perhaps even embarrassing experience.

Marilyn and Alex, however, "chose" to be models. They had high career expectations. Alex would be entering his father's highly successful company at middle-level management upon graduation. All of that would certainly be put on hold if he was suspended for sexual harassment. Marilyn wanted to enter graduate school as a clinical social worker, which would likely fail once it become known that she was suspended for sexually abusing another student. For both of them, the option of serving out the sentence as a human sexuality model seemed considerably less damaging or harmful, at least in the long run. In addition, it was only going to be one hour of one class, and once it was over, their academic record would be clean.

They arrived promptly as the class was about to begin, and were warmly greeted by Dr. Hirschfeld.

"It is so good to see you!" Dr. Hirschfeld shook each of their hands with considerable enthusiasm. A sense of relief swept over both Marilyn and Alex. So far, this was rather nice, hardly any punishment at all. Dr. Hirschfeld appeared to be quite friendly and considerate. Wouldn't it be amazing if this in fact turned out to be a walk in the park?

"Well, we have a lot to cover. Let's get right to it. Marilyn and Alex, if you wouldn't mind, why do you stand over here, in front of the desk, facing the students." Dr. Hirschfeld had arranged the class chairs-tables into a large circle, broken only by a gap in which rested his desk. The circular arrangement allowed for a generally unobstructed view of whomever was in front of the desk.

"Sure, Dr. Hirschfeld," they both replied. This wasn't hard. They both stood, as instructed, facing the class.

"Now students, is there anything sexual in what you see."

Marilyn and Alex furrowed their brows. They were not feeling particularly sexual. They were not trying to appear particularly sexual. Marilyn had in fact dressed relatively modestly that day. There was no way that she was coming to model for a human sexuality class dressed in clothes that could themselves be considered provocative or suggestive. She was instead wearing a conservative business jacket, covering a white blouse, along with a skirt and nylons, but that was hardly sexual. Alex was wearing a Ralph Lauren polo shirt with matching chinos. What the heck was Dr. Hirschfeld talking about?

Many of the boys, however, did consider the appearance of Marilyn to be sexual. Her dress wasn't inappropriate or provocative, but she was certainly attractive and appealing. Business skirts on woman with shapely legs was really quite provocative for a couple of them. However, they weren't so sure that this said more about their own aberrant preoccupations than with the appearance of Marilyn. They pretended not to notice anything.

Dr. Hirschfeld explained. "Young adults, whether single or not, will invariably provide signals of their mating potential. It is inherent to our species. Consider, for example, Alex."

Well, this really stumped the boys, as well as the girls. He appeared to be quite normal. Perhaps if he was wearing a muscle shirt, or really tight jeans. But, you couldn't see anything of his body. They couldn't even detect any cologne.

"Sociobiological research has indicated that, genetically, what women find most attractive in men is not always their bodies. Physical attractiveness does get a high rating. Physical attractiveness is a sign of physical health and strength, a signal that he is likely to be a good protector as well as a good provider for herself and her children. However, equally important for the ability of the male to protect and provide is wealth, power, and status. Wealth, power, and status will at times even trump physical attractiveness. And, how does the male demonstrate these qualities?"

Toni offered an answer. "By his clothes?"

"Precisely, Toni. Excellent. Alex is not wearing just any clothes. He is wearing a quite expensive polo shirt and chinos, and even those with the status symbol of Ralph Lauren emblazoned for all to see. It is a billboard of wealth and status."

Alex objected to the suggestion. "Dr. Hirschfeld, I really don't have any money or status. I mean no more than any other student my age."

"That's precisely my point, Alex. You don't have status or wealth, but you dress as if you do to provide an appearance that will attract the ladies."

Marilyn came to his defense. "I'm not interested in guys, Dr. Hirschfeld, for their money or power."

"Well, I beg to differ, Marilyn. You may not consider yourself to be attracted to such things, but there is considerable research to support this theory, and I am sure that you have yourselves seen many instances of women being attracted to men precisely for these reasons, whereas males much less frequently approach women because they are powerful, high status, or wealthy. It does happen, but there is a considerable differential frequency across the sexes."

Marilyn, Alex, and many of the students in the class had to admit that they did find this compelling.

"Now, what about the female of the species. How does she attract her mate? What is most appealing for the male?"

"Large breasts?" Hank suggested with a big smile, a suggestion that erupted considerable laughter among the students, and looks of disapproval by many of the girls, even those with large breasts. But, he was simply being honest, and he knew it was true for many of his friends, if they were being honest.

"Now students, quiet down. Yes, this is obviously true. But, why? Why do so many men enjoy large breasts?"

June offered her answer. "Because they remind them of their mother? When they were suckling as infants, their mother's breasts probably seemed to be real large to them." The girls smiled and nodded their heads at that.

"Well, June, that is a common theory, proposed in part by psychoanalytically oriented investigators. However, a sociobiological suggestion is that large breasts are again a sign of physical health, as well as an increased ability to nurture his young. The male, instinctively, is seeking a mate who will successfully produce and raise his young, a mate who will successfully pass on his genes for future generations. Small breasts will in fact be fully successful, but certainly during the long years of our genetic ancestry, the years of hunters and gatherers, larger breasts would likely have been considered more successful in nurturing, feeding, than smaller breasts. Hence, after many years of passing on this preference through the gene pool, most men today are sexually aroused by the sight of large breasts."

A lot of the students didn't really buy this theory, but they couldn't think of a better explanation, and it was a fact that many women enhanced their breasts to increase their appeal to men. Few ever reduced the size to little titties.

"Dr. Hirschfeld, " June countered, "you asked us what we saw in Marilyn and Alex that suggested sexuality. Marilyn doesn't appear to have large breasts."

"Maybe they are large," Hank countered, "We can't actually see them."

Marilyn flushed somewhat at the explicit reference to her breasts. The flushing was largely a self-consciousness, as all of the eyes of the students shifted to her breasts, but it was also a bit of annoyance with June, as she didn't appreciate June's suggestion that she was small-chested. She wasn't particularly large, but she was probably larger than June. She had to admit, though, that perhaps these thoughts only confirmed what Dr. Hirschfeld was saying. She was feeling rather competitive with another female over the size of her breasts.

"Yes, good point, June," Dr. Hirschfeld responded, ignoring the comment of Hank. "I wasn't meaning to suggest that Marilyn was using her breast size right now as part of her sexual display. I was only responding to the suggestion of Hank that large breasts do have a sexual appeal. One could in fact say that Marilyn is providing a counter-argument to the sociobiological position, as she is wearing a rather conservative business suit."

'Precisely my intention,' Marilyn thought.

"Now, it is true that you can hardly get a reasonable estimate of her breast size inside this suit. We will, however, get a better sense of this shortly."

'What?!' Marilyn thought, but she knew something like that this would be coming. She grimaced at the sight of the boys smiling, their eyes widening, at the thought of being able to see beneath her suit jacket.

"However, notice the skirt. Why do females wear skirts?"

"To show off their legs," Alan offered.

"Absolutely," Dr. Hirschfeld replied. "Perhaps regrettably, the primary stimulus for the male is physical attractiveness, a sign of physical health, and thereby the likelihood of the female being able to successfully birth and nurture his offspring. The sociobiological goal of the male is to spread his seed, and the single most important variable for this success is physical health. This is also in part why men prefer younger women. Women prefer older males, again because of their interest in obtaining a strong, powerful protector, and men prefer younger women, as signs of youth are also signs of health and fertility, as long as she is not so young that she is not yet able to reproduce. However, sociobiological models of pedophilia suggest that this disorder occurs in part because some males obtain an excessive loading of the genetic disposition for younger women."

"Marilyn doesn't look particularly young, Dr. Hirschfeld."

"Well," he smiled, looking at Marilyn himself, "not to you." She certainly looked young to him. "But, notice how so many women use make-up to hide their age, to make them appear younger; how youth has such strong sexual appeal."

June was not convinced. She did not use make-up to make herself look younger. She was quite happy with her age. "But, still, Dr. Hirschfeld, Marilyn is dressed in a manner that makes her look older."

"You are right about that, June. I'm not suggesting that the sociobiological model can explain every behavior, every decision, every preference." He walked over to stand behind Marilyn. "Nevertheless, despite her effort to appear as an older, mature woman. She nevertheless is wearing a skirt. And, besides showing her legs, why do women wear skirts?"

None of the students wanted to suggest an answer. Dr. Hirschfeld answered his own question. "It has many purposes. It is a gesture of flirtation, as well as submission." He reached down for the hem of Marilyn's skirt and said, "It's to let the male know that access to what he wants is but a flip of the skirt away," as he suddenly lifted up Marilyn's skirt.

"Dr. Hirschfeld!" Marilyn protested, grabbing at her skirt, trying to both push and pull it down to prevent the professor from lifting it any higher. She was largely successful, as Very little was revealed. Her skirt was so tight that Dr. Hirschfeld had not gotten it very high up before Marilyn had stopped him. All that was revealed was her white thighs and the top of her nylons. Nevertheless, he had made his point, as it was a rather flirtatious peek.

Dr. Hirschfeld was frankly surprised that she had stopped him, although he could understand her resistance as an instinctive impulse.

Marilyn, and the students, were in turn surprised that he did it. Marilyn knew that at some point she was going to have to reveal herself, at least to some extent. This was to be a substitute for participation within The Program. It was not going to be easy. However, it was an understandable shock to have Dr. Hirschfeld suddenly raise her skirt.

Dr. Hirschfeld let go and Marilyn quickly pulled her skirt back down, attempting to return it to a more appropriate and modest appearance.

"I am sorry, Marilyn, if I scared you. Lessons are at times more vividly understood and appreciated when they are unanticipated, perhaps even shocking."

Marilyn was grateful that he understood her reaction. She accepted his apology. "Well, I guess, okay."

"Let's now move on. If you would, why don't take off your jacket, blouse, and skirt yourself."

Marilyn looked to Dr. Hirschfeld, fruitlessly hoping that he didn't really mean it. But, she knew that he did. Marilyn and Alex both knew that taking off some of their clothes would be a minimal requirement of their chosen penance. Marilyn took a deep breath of courage and began to unbutton her suit.

One could hear a pin drop as Marilyn took her time unbuttoning. She was in no hurry, although perhaps that was a mistake. The longer she took, the longer she protracted her suffering. Perhaps she should just jump into the deep end of the pool and rapidly tear off her clothes. This was like slowing walking into a very cold pool, sustaining the pain, the agony, for as long as possible. However, she also appreciated that the whole experience would have to be over at ten to the hour. The longer she took taking off her blouse and skirt, the less time there would be for anything else that might follow.

She carefully laid the suit jacket on Dr. Hirschfeld's desk. She wasn't sure which should be removed next: her blouse or her skirt. Normally, the skirt would go next. It naturally followed the matching jacket. But, she was in less of a hurry to show the class her panties than her bra. But, either one was pretty embarrassing, to say the least. She turned her back to the class and undid the buttons of her white blouse, including the cuffs.

When she was finished she withdrew her arms from the sleeves and then carefully folded and laid her blouse on her jacket. She looked down at the exposed pink cups of her bra. She couldn't believe that she would shortly show these to everyone in the class. Those to her side could already see the round cups poking out and she felt that she could literally feel the eyes of the boys behind her burning into the exposed skin of her back. She looked back over her shoulder.

It was true. She wasn't showing much, but many of them had not yet seen a girl undress before and now, right before their eyes, was the bare naked back of a pretty girl, showing them the straps of her pretty pink brassiere. So many wanted the opportunity to be the one to unclasp her bra. She turned her face back to the blackboard. She couldn't stand seeing all those ogling eyes on her. She reached back and pulled down the zipper of her skirt. A partial view of her pink panties could be seen, a little taste of what would soon come into view.

Normally she would entirely unzip her skirt before stepping out from it, but that would require bending over and she wasn't about to do that in front of all these students. When she had enough unzipped she wiggled her behind to let the rest fall to the floor. She could hear a few gasps from behind her, and a bit of murmuring and whispering.

Marilyn did have the cutest little bottom, and it looked all the better so nicely wrapped in her pink cotton panties. She was not wearing any of her sexy lingerie. She had known full well that it was quite possible that her undies would be exposed in class and she was not about to make it worse by wearing sexy lingerie, suggesting that she actually wanted to be seductive.

On the other hand, she also didn't want to be wearing her entirely boring, unattractive, even ugly underwear. That might even be more embarrassing. Imagine taking your clothes off in front of a room full of guys who react with indifference, or even laughter. And, then, to be the brunt of jokes and gossip on campus about the cheep ugliness of her panties. So, her compromise was a matching pair of plain pink cotton panties and bra. Well, not entirely plain.

Marilyn stepped out of her skirt, keeping her bottom toward the class. She bent her knees to carefully, demurely squat down to pick the skirt up, being careful not to bend over and offer any suggestive pose. She folded and laid the skirt on her blouse. She looked over at Dr. Hirschfeld. He gestured for her to turn around and face the class. She took a deep breath and did as she was told.

Marilyn, however, faced the class with her right arm covering her breasts and her left hand covering her pubic area. There was nothing though covering her face, and her self-conscious embarrassment was utterly exposed as her face was as pink as her panties and bra.

Dr. Hirschfeld had been waiting patiently for Marilyn to undress. He did not want to rush her. He could see her ambivalence, her uncertainty, her fear. He knew to push her too hard too quickly may only drive her from the class. He did now though finally speak. "Well, class, Marilyn has taken a natural pose of modesty, covering herself as she presents herself to the class. However, I must honestly say that I consider this pose to be one of the more enticing and alluring that a girl can provide. It is telling the male that she fully appreciates how exposed and vulnerable she feels. Frankly, it would be less provocative if she appeared to be simply indifferent to her state of undress, as if there was nothing sexual or provocative at all about her appearance."


Modeling for the Class



Marilyn could understand his point. She vowed then to maintain her composure. If she didn't act embarrassed or ashamed then she wouldn't be humiliated or shamed. She let her hands drop to her sides, and she even raised her head in pride, thereby thrusting our her titties to the class.

The boys would have to disagree with Dr. Hirschfeld. They found Marilyn's hands by her sides to be much more appealing than covering her sweetest spots. Her brassiere was a three-quarter, demi cup underwire, that nicely accentuated her exposed cleavage. Neither the panties nor the brassiere, however, were sheer. One could not see what they were hiding. But, they nevertheless complimented well what was being hidden. Her breasts were not large, but they were so beautifully shaped. They seemed to be perfectly round pink snowballs.

James was entranced. A girl was standing right before him, right in class, wearing only her bra and panties. His dick was straining against his trousers, although he also felt a bit guilty about that. He could see that Marilyn was quite uncomfortable in being so exposed. He couldn't imagine having to stand in front of the class like that. But, still, how could he not look? He knew what he would be thinking about tonight. His collection of films would be put aside as he recalled the sight of Marilyn with her pink tittie bra so openly displayed and, even better, her sexy pink panties. He wondered if they would be able to see more. He wanted to ask, but was much too self-conscious to do so.

Marilyn became intensely uncomfortable with all the staring. Her resolution to be indifferent did not last long. She felt such an intense urge to once again hide herself with her hands, but that would be such a terrible admission of surrender. Her hands though just had to do something. It felt so odd to just have them hang there, by her side, as so many eyes stared at her brassiere and panties. She clasped them behind her back. This did at least let them hold onto something, if only each other. However, resting them against her soft, pantied bottom only reminded her of how she was wearing so very little. She shifted her legs, bending one leg and turning it in to try to perhaps hide her cunnie with her thigh.

It was an ineffective effort. In fact, it only made her look more appealing, if that was possible, like she was demurely presenting herself to her lover, showing herself to him, but feeling so self-conscious at the same time.

"Well, now," Dr. Hirschfeld exclaimed, "this is much better. As you can see, Marilyn is wearing a very appealing bra and panty set, very appealing indeed," gazing at Marilyn's delectable pink peaches. Speaking to the students, "you may not realize that the brassiere has not in fact been around that long. The first modern brassiere was invented in 1913 by a New York socialite, Mary Phelps Jacob. She had purchased a sheer evening gown and found that the whalebones of the traditional corset were too obvious. She designed her own alternative, with the help of her French maid, Marie, using some silk handkerchiefs and pink ribbon." To accentuate his point, Dr. Hirschfeld matter-of-factly cupped each of Marilyn's breasts in his hands, molding and lifting them like a brassiere, enjoying in the process their soft pliancy. Marilyn flinched and blushed with confusion at the intimacy of his touch. "She got a patent for her 'backless brassiere in 1914 but sold it to a corset company for just $1,500, who then made more than 15 million dollars over the next thirty years." Marilyn squirmed as Dr. Hirschfeld softly felt her stiffening nipples. "One should not, though, feel too sorry for her. Another Mary, Mary Tucek, had patented a brassiere in 1893 that was actually closer to the modern design."

The girls found this lecture rather interesting. The boys just studied Dr. Hirschfeld's hands softly squeezing and exploring Marilyn's breasts, imagining what they would look like wrapped in tightly clinging silk handkerchiefs, wondering if it would be inappropriate to request first hand knowledge of how her brassiere felt to the touch.

Dr. Hirschfeld released his grip on Marilyn's young breasts, very reluctantly so, but much to the relief of Marilyn. She breathed a noticeable sigh of relief as his hands left her bosoms. She could feel a palpable sense of reprieve sweep over her.

"Yikes!" she yipped. Dr. Hirschfeld had grabbed the waistband of her panties and pulled them up sharply, as if he was giving her a wedgie. "Dr. Hirschfeld!" she complained, getting up on her tip toes, even hopping a bit, trying to escape this affront.

Dr. Hirschfeld was not actually trying to give her a wedgie. Her panties didn't even fully ride up her crack, although the whiteness of her pert cheeks came nicely into view. In any case, it wasn't actually her bottom that was the focus of his exercise.


"Class, I may have pulled these up a bit too tightly, but you can see how a pair of panties can be even sexier when they are fitting tight to the body. A girl should really purchase a pair that are a bit small." He bent over a bit and pointed with his finger. "See? See? Marilyn now has a nice pretty little camel toe," indicating the crease within her panties molding to her slit. "It's such a pretty little thing. Don't you agree?"

Marilyn had to cover her eyes with her hands. Many of the girls were also embarrassed for her, whereas the boys chuckled. James thought, 'Well, that's what a camel toe is.' He had always wondered. It did look awfully sweet. He reached down and touched his erection, but quickly pulled his hand away, fearing that he would get caught.

Dr. Hirschfeld was himself feeling a natural reaction within his own slacks. Before it became too noticeable he let go and turned his attention to Alex. Marilyn quickly fixed her panties, doing her best to remove any further signs of her camel toe. She even pulled them down a bit to make them loose within her crotch.

"Alex, let's take a look at your undergarment."

"Sir?"

"Your clothes, Alex. Off with the shirt and slacks."

"But, um, sir." Alex had also developed a natural reaction to watching Dr. Hirschfeld fondle Marilyn's breasts, as did many of the boys in the class. It was difficult enough to drop your slacks in front of the whole class, but doubly, no triply, difficult if you're sporting an erect cock.

"Is there a problem, Alex? You certainly don't want Marilyn to be undressed all by herself. Now, would that be fair?"

Alex spoke somewhat quietly. "I don't think it's a good idea, not right now, sir." He couldn't bring himself to explain to Dr. Hirschfeld precisely why he was hesitating. Saying out loud that he had an erection was almost as embarrassing as physically revealing it. Delaying the display, as well as avoiding any further glances at Marilyn, might provide enough time to lose it.

Dr. Hirschfeld, however, would have none of it. Alex had fully agreed to this service to the class as his atonement for his harassment of Chrissie and he was getting a bit impatient with his delay. "Alex, if you prefer, we can call it off right now and I'll proceed without you."

Alex really didn't want that. This one hour of modeling was so much better than a suspension and permanent black mark on his record. He began to unbutton his shirt.

Alex took about as long as Marilyn. Unlike the boys, however, the girls enjoyed the fact that he was taking his time. It was like he was purposely trying to tease them, ever so slowly revealing the masculine hair on his chest, his well defined pecs, his tight biceps, his taught abdomen. He was indeed in very good shape.

The girls' eyes widened with delight as he turned his back and pulled down his slacks. They were not disappointed. Alex was wearing loose, Ralph Lauren boxers and, much to his dismay, he was still sporting much of his erection. The delay didn't really help, as he couldn't get it out of his head that he was about to be standing only in his underwear in front of quite a few girls, one of them dressed only in her pink bra and panties. He blushed furiously as he turned to face the class.

Gasps and squeals shook the class at the sight of the tent pole jutting out from Alex's boxers. The girls were giggling, pointing, and chattering. They knew that when they had enrolled in Dr. Hirschfeld's Human Sexuality class that it would be one of the better experiences at Abberville, but nobody had imagined this! They were actually being presented with the sight of a boy's hard-on poking out his drawers. It was both exciting and funny; quite a nice combination.

This was close to Alex's worst nightmare. Many times he had been worried about getting an erection in front of a nurse, or during gym class. In fact, this might be worse than his worst nightmare, as he had to stand there and just let them look and laugh at his embarrassed state.

Marilyn was amazed and confused. She had not herself seen a male erection before, and this was one on her modeling partner. She couldn't bear to think what this might mean for her. Her hand went to her mouth and her eyes went back and forth between Alex's boner and Dr. Hirschfeld's eyes, hoping to see in them some sign that this was considered to be inappropriate and that he would quickly put a stop to it.

Dr. Hirschfeld, however, had no such intention. He hardly seemed to notice it, let alone care. "Well, it seems that our young Mr. Brandon even feels it's necessary to wear the Ralph Lauren symbol on his undies, as if a girl was going to see that as well."

Alex did not care for that belittlement. He boldly defended himself. "Well, Dr. Hirschfeld, quite a few girls are in fact looking at it right now."

Dr. Hirschfeld was impressed with Alex's assertiveness. However, he retorted, "Very good point, Alex, but I suspect that the eyes of the girls are not directed to the label. There seems to be something else that is drawing their interest." That valid point silenced Alex. None of the girls were thinking about the expense of his drawers. They were clearly fixed on the sight of his stiffie pushing out against his loose boxers, shifting around in his drawers as Alex turned toward and away from Dr. Hirschfeld, as if his hard snake was trying to find a way out.

A useful feature of Alex's boxers was the very open, loose flap that allowed for ready access. However, it wasn't so useful now, at least from Alex's perspective. From the perspective of the girls, it turned out to be very useful. Alex's hard cock suddenly slipped through the loose flap, like a jack in the box that suddenly escaped its confines and proudly displayed itself for the class.

It really did look like it was happy to get out, it was jutting out so proudly, so augustly. Alex quickly tried to hide it from view with his hands.

"No, no, Alex," Dr. Hirschfeld admonished him. "We would at some point turn our attention to the male erection. It's fine to begin the instruction at this point. I'm certainly flexible with regard to what is covered when, although I can see that you aren't particularly flexible right now." He smiled at his own, rather pathetic joke.

Alex was not smiling as he agonizingly pulled his hands away, exposing to full view his stout, naked, jutting cock.

The girls' eyes widened in shock. A couple of them even covered their eyes. "Now girls," Dr. Hirschfeld corrected them. "Let's be mature adults here. I want to you take a good look at Alex's penis." Some of the girls appeared to be blushing harder than Alex.

Marilyn's mouth opened in further shock. This was certainly well beyond any reasonable request for modeling, although she had to admit that she didn't object to the presence of Michael's erection during his participation in the program. On the contrary, she had teased him about it. Nevertheless, she was having quite serious doubts about her choice to model for Dr. Hirschfeld's class.

"That's a fine erection, young man." Dr. Hirschfeld was sincerely impressed. He did not himself obtain as stout of erections as he had as a youngster, and he was feeling a bit envious. "One of the euphemisms for an erection is, of course, a 'boner.' How many of you are familiar with that term?" A few of the students reluctantly raised their hands. They weren't so sure that it was desirable for them to acknowledge their familiarity that term. James quickly brought his hand down when he realized that only a few of the students had raised their hands. The boys were embarrassed by the impression that the term was rather childish. The girls, on the other hand, were concerned that familiarity implied they were themselves sexually active, perhaps even loose, women, who were intimately knowledgeable of the male boner.

Dr. Hirschfeld could see their reluctance. "Now, now, come on kids. If Alex is not embarrassed by displaying his boner for us, we certainly shouldn't feel reluctant in acknowledging what it is called. But, in any case, 'boner' is really just descriptive. There is, of course, no bone holding up the penis, nor is it a muscular reaction. The primary physiological mechanism is the autonomic dilation of arteries supplying blood to the penis which fills three spongy erectile tissue chambers, causing it to lengthen and stiffen." The students started to take furious notes. A few of the girls were very relieved to have a reason to look away, although others were disappointed for the same reason. "The engorged erectile tissue also presses against and constricts the veins that carry blood. More blood enters than leaves the penis until an equilibrium is reached where an equal volume of blood flows into the dilated arteries and out of the constricted veins; a constant erectile size is achieved at this equilibrium."

All of the boys were entirely familiar with erections, but none of them actually knew how it happened. Heck, they had to admit that they were actually learning something in this class.

However, the clinical description of his erection, coupled with his embarrassment at having to openly display it for so many strangers, was allowing for blood to flow out and it was clearly beginning to droop. It first just dipped down, like a crane lowering to pick something up, and then the crane itself lost its steely hardness and began to droop.

Jennie raised her hand and spoke up. "Dr. Hirschfeld, I think his boner is softening."

Dr. Hirschfeld had himself been lost in his lecture and had not noticed. "Oh my, yes, Jennie, thank you for pointing that out."

She replied, "Your welcome, Dr. Hirschfeld," feeling rather proud of being the one to first notice, although nobody in class could have missed it. It was just that Jennie was the first student to be bold enough to mention it.

"Well, we will need it to be fully erect to discuss it's anatomy. Marilyn, why don't you help the young man out."

Marilyn's eyes grew even wider, if that was at all possible. She shook her head in abject consternation. "Dr. Hirschfeld, you don't really want me to touch it, do you?"

"Well, certainly, Marilyn. We can't have the young Mr. Brandon handle himself in front of the class. That would be putting him in a rather awkward position, don't you think, young lady?"

Marilyn could certainly understand the humiliation Alex would feel at having to jerk himself off in front of the class, but didn't Dr. Hirschfeld appreciate that it would be equally awkward, if not appalling, to ask her to do it for him? "Dr. Hirschfeld, I mean, well, I've actually never done that before, for a guy."

Some of the girls giggled at this admission, whereas others were feeling rather sympathetic. The boys eyes widened at thought of being able to watch the sexy Marilyn, dressed in only her panties and bra, give her first hand job.

Marilyn's face flushed with this admission, as well as the giggling, but the embarrassment of admitting her naivety to the whole class was worth the cost of actually having to handle Alex's naked penis.

"Outstanding, well that settles it. All the better. You will be learning something new as the class is being instructed. Here, I will help you. Use your left hand."

Marilyn hesitated. She couldn't believe that he was asking, requiring, her to touch a man's naked erection. It felt like she was being asked to grasp a hot steal rod.

"Come, come, Marilyn, don't be shy. It won't bite you."

More giggling could be heard. Marilyn didn't care for the suggestion that she was afraid of a boy's erection. She reached out for it.

"It might spit on you, but it won't bite." Lots of the students laughed at that, and Marilyn quickly drew her hand away. There was simply no way that she was going to jerk Alex off to an orgasm, and doubly no way that he was going to ejaculate onto her.


Dr. Hirschfeld apologized for his insensitive indiscretion. It was funny. The class' reaction confirmed that impression. But, it was also at Marilyn's expense and he did not want anything inappropriate to occur during this sensitive class exercise. "I am sorry, I do apologize for that flip remark. But, now, please, take it in your hand."

"You promise he won't ejaculate on me."

Dr. Hirschfeld knew that he really couldn't promise anything like that, but he also knew that he had to reassure Marilyn. "I will keep a close eye on its status."

Marilyn looked Alex in the eyes as well. She said quietly, "You better not squirt on me, Alex Brandon."

Alex's erection was rapidly diminishing. He was frankly quite ambivalent about getting it back. However, he knew that it was inevitable that he would have to show it again and, besides, it was certainly preferable to be displaying a proud hard-on than a wimpy, dangling limpness. And, finally, he was very happy to hear that it would be Marilyn bringing it back rather than himself. He whispered, "I won't, Marilyn, I'll let you know if it gets that far."

Marilyn carefully, reluctantly, gingerly, wrapped her fingers around the shaft. A light shiver swept through her body at the touch of his naked, stiff maleness.

"Now, Marilyn, don't start stroking or jerking quite yet." His declaration was not really necessary. Marilyn was in no hurry. She was just trying to get used to the feel of it in her hand. "Just feel the fullness of it all. Actually, let your fingers first drift down to his testicles." That seemed awfully gross to her, but she did as she was told.

"Ever_so_gently, lightly, grasp them in your fingers. A lot of men enjoy a gentle stimulation of the testicles, which can involve licking, tugging, or simply cradling the scrotum."

Susie asked, "Girls will actually lick them?" That seemed like an awfully gross idea to her, and to Marilyn. There was no way her mouth was going to make contact with this wrinkled, hairy sack.

"Well, certainly. There are many ways of stimulating each other sexually. Actually, Alex here appears to have a couple of Grade AA eggs himself, and Marilyn, to get a feel of their weight, why don't you just lightly bounce them up and down on the tips of your fingers."

She did as she was told, and she had to admit that this was a bit fun. They felt like soft eggs.

"Now, see if the young man is ticklish behind his sack. Many men are. Just lightly dance your fingers around behind there."

She followed his instructions and got an instant confirmation. Alex bent forward, an expression of both mirth and annoyance on his face. Yes, he was indeed ticklish there. This drew a smile even from Marilyn.

"Tickling can play a significant role in some sexual foreplay. Frankly, it's not really known why people are ticklish, and it is particularly curious that we can't seem to tickle ourselves. It is perhaps because tickling requires a certain amount of surprise."

Marilyn surprised Alex by tickling him behind his balls again. "Cut it out!" he complained, but his own squirming and instinctive giggle revealed that a part of him did enjoy it. The girls liked the fact that his penis bobbed and swung with his squirming.




Modeling for the Class



Dr. Hirschfeld enjoyed the fact that his models were now getting into it. He continued his lecture. "Because tickling oneself produces no unexpected motion on the skin, the response is not activated. Recent MRI research has indicated that the brain distinguishes well between sensations we create for ourselves and sensations others create for us. "C'mon, c'mon!" Alex pleaded as Marilyn continued to demonstrate the phenomenon for the class, now giggling herself as she made Alex jump and squirm. "When a person tries to tickle himself the cerebellum sends to the somatosensory cortex precise information on the position of the tickling target and therefore what sensation to expect." Alex tried to escape by pushing her hand away, but Marilyn ended that by taking a firm hold of his balls, causing him to bend over, this time with considerable discomfort. "Yes, well let's move on. If you would not mind, Marilyn, bring your fingers back to his shaft."

Reluctantly, she did as she was told. "Now, just let yourself explore the feel of his shaft, the soft crown. Explore every square inch. A man loves to have his penis explored, fondled, caressed. Let him know that you are not afraid or ashamed to be touching him there." Marilyn though was quite afraid and ashamed to be touching him there, but that did not in fact bother Alex. On the contrary, he enjoyed the fact that she was so clearly very reluctant, so inhibited. After her tickle torture, the fact that she was being forced to do this, dressed only in her panties and bra, made it all the more pleasurable. His notably swelled.

"Excellent, my dear. Yes, you're doing a fine job."

Normally Marilyn would respond to an instructor's compliment of her performance by expressing some gratitude for the praise, but she was not particularly proud of this.

"Now, class, you notice that Alex is not circumcised and this can be quite an advantage during masturbation. Marilyn, grip his hardening shaft firmly with your hand and ride your first up and down."

Marilyn turned her body so that she was looking away from the class. She could not look anyone in the eye as she did the deed. It was just too humiliating, too degrading, to be yanking off a guy in front of the whole class.

Jim regretted her turning away as he missed the display of Marilyn's pink covered titties, but he was now treated with the sight of her tightly wrapped bottom, which itself squirmed and wiggled as she handled Alex's cock. Now he had even more for his evening fantasy, imaging having Marilyn's hand jerk him off.

"You can see, class, how his foreskin is sliding on and off the swelling bulb of his penis. It's like he has his own personal vagina that is massaging, milking, his penis.

Marilyn was looking away but she could not hide from the fact of what she was doing and Dr. Hirschfeld's verbal description didn't help. "You can even now hear the sound of Alex's precum leaking out. This is to help lubricate for eventual entry into a woman's vagina." Marilyn squeezed her eyes shut at the thought of that, and at the sound her stroking was making, a sort of squishy slapping noise as she jerked on Alex's penis, which was now very stiff and hard in her little hand.

Obviously, Dr. Hirschfeld was not going to have Alex insert his penis into her vagina. That was well beyond anything appropriate, but if he was even remotely considering it Marilyn decided that it might be best to put Alex out of action and bring him to orgasm with her hand. She doubled her efforts and was now rapidly, seemingly eagerly, jacking him off.

The room was filled with the slapping and slurping sound of Alex being jerked off, and all eyes were fixed on the sight of his engorged cock. The head of his stiff dick now fully swollen, like a ripe plum ready to be bitten, sliding in and out of his foreskin and Marilyn's rapidly moving fist.

Dr. Hirschfeld could see that Alex was indeed getting close and, as he had promised Marilyn, he ended the task. "Whoa, you better stop, Marilyn. I think the young man is getting ready to shoot his rocket."

That was precisely Marilyn's plan. If he was in fact close, then it was best to just finish him off. She ignored Dr. Hirschfeld's instruction and leaned into Alex, pressing her bra covered breast to his shoulder and whispered, "Do it, Alex, squirt your thing, let it squirt."

Alex reached up to grasp her right breast with his hand.

Marilyn grimaced at this uninvited, intimate touch, but she did not pull away. This shameful sacrifice was, perhaps, worth the avoidance of any actual intercourse.

Dr. Hirschfeld though stepped in and pulled Marilyn's hand away from Alex's erection. "Marilyn, my goodness." He turned to the class as he pulled her away. "I guess once she got her hand on a young man's erection, her natural instincts just took over."


There was little reaction from the class at this remark, as they were also rather stunned at the sight of Dr. Hirschfeld having to literally pull Marilyn away. Marilyn blushed deeply, as that wasn't it at all. She considered telling Dr. Hirschfeld her real motivation as she certainly didn't like his public suggestion that the touch of a boy's erection had turned her into an uncontrolled nymph, but she also didn't want to bring up her fear of having to engage in intercourse. For all she knew, he would just take the idea as a good suggestion. She stepped back from Alex, her eyes fixed on his hard-on, a look of frustration on her face, a look that was perceived by many in the class as a sexual frustration at being denied. Every boy in the class was now sporting an erection just about as hard as Alex's, and a few of them were lightly tracing their fingers around and around the soft round heads that were poking up through their pants.

"Well, that's now an excellent erection, Alex. Why don't you let a few of the girls in the class get a good look at it."

Their eyes lit up with the suggestion, as did Alex's. 'Was he serious?'

"Certainly the boys have had a good look at their own erections." Some of the girls glanced at boys nearby, smiling knowingly at the thought of them studying their own boners. Their hands quickly shifted away, but not before being caught by a number of the girls, who giggled at their embarrassment over their indiscrete behavior and resulting state. "It would be useful to let the girls get a closer look." He directed Alex to move along the circle of desks. "Here, bring it up to the girls so they can inspect it."

Alex sighed with frustration. He was, putting it mildly, really uncertain about this. Showing off his erection for a lot of pretty girls could be plenty cool, even when they are themselves fully clothed. But, he did feel a bit infantile, like he was a little boy or something, being forced to show himself to his sister's friends for their own devilish amusement.

"Now girls, the head of the penis is called the glans." Stephanie leaned in close. It was indeed pretty interesting, so red and swollen. "At the tip is the urethral opening, where both urine and semen are expelled."

"Eeeuuuw!" she exclaimed, and backed away. Alex moved down to the next girl, June.

June grasped the bulb with her thumb and forefinger, and squeezed, causing his pee slit to open up. She peered down inside and asked, "Why do guys use the same hole?" as if the guys actually had a choice regarding their anatomy. "Girls use different things for their." Her voice quieted, "for her, um, you know, urine and his stuff." She flushed at what she was talking about. She appreciated that you had to talk about quite a bit of personal stuff in Human Sexuality class, but that fact didn't always make it any easier.

It was no easier for Alex, to say the least, as he moved around the class. He was really quite confused over how to react. He liked it when the girl was softly exploring the feel of his cock. It was like he was being given one virgin hand job after another. That's gotta be pretty good. However, some of them, like June, put an end to that by making it all clinical. It certainly wasn't appealing, at least to him, to have a girl squeeze open his urethra track and peer down inside, like he was some sort of queer species at the zoo.

"That's a very good question, June. We, of course, don't know the answer. The intelligence of the design can be a mystery. Was it in fact an intelligent design? Or, alternatively, why would separate channels evolve for a woman but not for a man?"

Alex moved to the next girl, Mary Beth. It was like his erect cock was serving as a microphone, providing the girl with the opportunity and right to speak. Mary Beth tentatively grasped hold of the shaft and drew it to her. She had never felt one before and she wasn't quite sure what it would be like. As she slid her fist up and down the shaft, she suggested, "Well, the girl's canal, you know, her vagina inside, um, that, well, that's where the sperm will go to make a baby." She was somewhat distracted by the sight and feel of the hard cock in her enclosed fist. "You wouldn't want it to be infected by urine and stuff like that."

Alex moved to the next girl, Nancy. Nancy didn't even want to touch it. She pulled it toward her with just the tips of a couple of fingers, and then sniffed. Alex could see her grimace. He had to admit that he could now detect the smell of his own arousal. One would wish, though, that a girl wouldn't find it aversive. His dick popped back as she let go of it. She offered, "Wouldn't the male's urine sometimes get mixed with sperm as it leaves the urinary tract?"

All this talk was making it so asexual for him, like he was some sort of laboratory frog.

Alex quickly moved on to the next girl, Susie. Fortunately, or unfortunately, Susie was very interested in Alex's cock. She had felt a guy's cock before. She was not inexperienced, although certainly not a woman of the world by any means. She wouldn't kiss it or anything like that, but she did enjoy the feel of a good cock. The tips of her fingers drew slowly up his shaft, and then softly, playfully, she slid them around and around the swollen bulb, enjoying the feel of the moist precum. She said, "Yea, but imagine a guy having two penises, one for sex and one for peeing. He might get confused about which one to use." All of the girls, and even many of the boys, laughed at that. "I suppose only one of them would become a boner though. Such a shame." She smiled flirtatiously up at Alex.

Alex didn't want to leave Susie, at least not her teasing fingers. However, he knew that if he stayed much longer he might have an accident. His balls were really beginning to throb.

Dr. Hirschfeld attempted to get the class more serious. "For most boys the area with the greatest sensitivity is the frenulum." Alex was standing in front of Becky at the time. "Becky, push his penis up so you can see underneath." She gleefully followed his instruction. "You see the indentation on the underside of the penis where the glans meets the shaft? This is part of his foreskin, where it is attached. It's actually identical to the frenulum that secures your tongue to the floor of your mouth." Becky grimaced at the thought that she had something like Alex's penis's foreskin inside of her mouth. Actually, a lot of the girls felt their stomachs turn at that. The boys, however, chuckled, although they also found the thought a little disgusting. Dr. Hirschfeld continued, "The foreskin's frenulum holds it in place over the glans, and, in conjunction with the smooth muscle fibers, helps return the retracted foreskin to its usual forward position. Becky, why don't you demonstrate by pulling his foreskin on and off his glans."

Becky happily did that, playfully demonstrating how the foreskin moved on and off, like she was in fact jerking him off, which was certainly how Alex was experiencing it. The bulb of his dick swelled further and grew darker. The students silently watched as the class was treated with soft slurping sounds as his pre-cum seeped out and lubricated the foreskin's sliding on and off his crown.

"Excellent job, Becky," Dr. Hirschfeld commented. "The wet sound you are hearing is Alex's pre-cum, his lubrication, once again coating his glans and foreskin. It's good that it does, because if he was entirely dry it could become quite abrasive and chafed."

"There's another way that Becky could make it wet," Tina suggested.

Everyone knew what she meant, and quite a bit tittering, and embarrassed giggling, swept through the class. The boys' laughter was a bit stronger and certainly more gleeful. Becky let go of Alex's penis. She was not about to do that, and certainly not in front of everyone. She looked over at Dr. Hirschfeld. She thought, 'He wouldn't really ask me to do that, would he?'

"Now students," Dr. Hirschfeld admonished. "Let's be serious here. Yes, of course she could do that. Would you girls like to see the male ejaculation?"

The class grew quiet. Most of the girls certainly did, but most of them were equally certain that they didn't want to admit it. Becky definitely didn't want Alex to do it right now, not while he was aiming his thing at her.

"Here, Marilyn, you can be helpful with this. Alex, why don't you come back up here next to Marilyn and see if you can successfully execute a male ejaculatory response."

This sounded awfully disgusting, at least to Marilyn. A little while ago she was actually trying to get Alex to ejaculate. But, at that time, she was doing it freely and, more importantly, secretly, in order to avoid him being able to put it in her. Marilyn wouldn't mind giving a future boyfriend a hand job. That was something that a girlfriend should be willing to do and, she had to admit, she had been looking forward to the day when she would be doing things like that with a guy; but, of course, with a special guy, her guy. Dr. Hirschfeld was instead asking her to give a hand job to a guy she just meant, and right out in public, in front of a class of students. That was terribly different.

Well, she had been doing it before. How bad could it be?

"Marilyn, if you wouldn't mind." She certainly did mind. "Grasp his shaft again and resume the stroking you previously had applied. It was effective before. I imagine it should do the trick."

Marilyn reluctantly reached out again for Alex's cock. Once she had it in her hand she looked away. She really didn't want to watch herself jerk him off.

Dr. Hirschfeld continued his lecture. "During sexual stimulation, semen collects, of course, in the ejaculatory ducts located where the vas deferentia joins the seminal vesicles within the prostate gland." The students hurriedly took notes in case this was going to be on the test, but they did their best to keep their eyes on the models or, more specifically, the sight of Marilyn's hand jerking up and down Alex's engorged cock. "When stimulation reaches climax, a spinal reflex causes contractions to the muscles within the penis, urethra, and the prostate gland. These contractions propel the semen through the urethra and out of the tip of the penis." Alex thought that he could almost feel his prostate getting ready to cock and shoot. Marilyn, however, her face turned away, grimaced at Dr. Hirschfeld's description, and the thought of it actually happening. "Although male ejaculation and orgasm occur simultaneously in most cases, they are not actually the same process. An orgasm, specifically, is the rhythmic muscular contractions that are a release of accumulated sexual tension and result in an intensely pleasurable sensation."

Alex was certainly looking forward to that. He was feeling a very strong need for the release of "accumulated sexual tension." He focused his attention on the cups of Marilyn's brassiere. He had been avoiding looking at her before, not wanting to have an accidental relief of sexual tension. But, now, his cumming was the assignment. His balls were aching so bad. He let himself admire the prettiness of Marilyn's breasts, all dressed up in pink. She did not look particularly excited about jerking him off, but that didn't matter. It would still be a girl's hand, a pretty girl, and one dressed only in her panties and bra that would bring him off. And, once again, in some odd way, the fact that she was doing it reluctantly provided even more pleasure. He thrust his hips out a bit, providing more prominence to his stout shaft.

"Actually," Dr. Hirschfeld interjected, "It does look to me that Alex's penis might need a bit of moisture." Marilyn stopped dead in her jerk and turned to Dr. Hirschfeld, though still gripping Alex's hard dick.

"What do you think, Alex?"

"Well, it would help, sir." He knew that it wasn't really necessary. It was fine, but if he understood Dr. Hirschfeld correctly, he wasn't about to disagree.

"Yes, it may have dried off a bit with all the discussion. Marilyn, if you wouldn't mind, why don't you moisten the young man."

The class was dead silent. Marilyn's face turned a beet red. When she had agreed to model for this class, she had not imagined that it would ever go this far. This was well past her expectations, and willingness. It would have to be a mighty desirable guy to allow him to place his thing in her mouth. It's not that Alex wasn't attractive. He was very attractive, but she meant in the sense of somebody with whom she was deeply attached, committed. It would have to be an act of love, not a public service.

Dr. Hirschfeld ignored her hesitancy. "Oral sex, of course, is nothing to be ashamed about. It's a natural part of the human sexual act. I was not anticipating a demonstration so soon within the class, but with Alex's impending orgasm, I think it might help to move along a bit more quickly." He walked up to Marilyn and placed his hands on her shoulders. "A common position for this act is for the woman to be kneeling before the man, literally on her knees." He lightly pressed down on Marilyn's shoulders to encourage her to get into the proper position.

Marilyn really wanted to say no. But, she already gone so far. It would be a shame for all that she had done, had survived, to go to waste. And, she frankly wondered as well if it might only get worse if she reneged on her agreement, although she couldn't imagine it getting any worse than this. However, if President Rayburn endorsed public displays of nudity in classes; well, he might indeed having something in mind that was much worse. And, finally, again she realized, she just really had to avoid having a suspension on her permanent record. She let Dr. Hirschfeld push her down on her knees.

The boys leaned forward in their chairs. Some of the girls actually leaned back, in a sympathetic aversion to what she was about to do.

Marilyn stared at the swollen cock, now just a few inches from her eyes. It looked so much bigger from this angle. She in fact felt quite submissive, subservient, in this position, kneeling before Alex, his entire body towering over her, his hard cock in particular. This was going to be really, really difficult.

She once again grasped his cock, pulled down on the shaft, closed her eyes, opened her mouth, and moved her face forward until she felt the swollen bulb slip by her lips and into her mouth.

It felt so weird, so terribly weird, to have the big soft bulb of a boy's hard cock in her mouth. This is what he pees out of! She hoped she wouldn't gag. It didn't at least taste real bad, or smell real bad. It had a sort of musky smell. She was worried that it would smell like a used jock strap or something; not that she had ever smelled anything like that, but they must smell similar to body odor and she had certainly smelled a lot of that on guys. Why didn't they wash more often?

She glanced to her side and felt another flood of blood sweep through her face. The taste and smell wasn't the real problem. It was the fact that she was doing it, that she had a cock in her mouth, and in front of everyone in the class. She never felt so humiliated, so shamed, to be doing this in front of strangers. She could see Jim's eyes popping out of his head. 




Modeling for the Class



Although, actually, it would be terribly worse if she knew one of the students in the class. Imagine having to suck a boy off in front of your girlfriends, or in front of a guy she was attracted to! Their eyes would be even more painful to see. What would the guy think? What would he expect? She imagined that she would get all sorts of invitations to go out after it was over, being thereafter always expected to be willing to go down. She closed her eyes to block out the sight of the boys' eyes.

"This act of love is really quite intense for the male. The woman is showing her man that she will do just about anything to please him, even to the point of letting him place within her mouth the organ with which he urinates."

'Thanks for putting it that way, Dr. Hirschfeld,' Marilyn said sarcastically to herself..

"Make sure you get it all wet, Marilyn. Boys like it when you use your tongue. It's also quite intense because the head is terribly sensitive and the licking, massaging, and lathering of the tongue can be extremely stimulating, and be sure to continue to use your hand on his shaft. Try to be stimulating the entire organ."

Marilyn obediently slid her hand up and down his stiff shaft, as well as tonguing his bulbous head.

Alex groaned in appreciation. He never had a blow job before. A blow job alone would be enough to make this end quickly. It was even more difficult to hold out given how much stimulation had preceded Marilyn's warm, soft, wet tongue, now exploring the contours of his cock. He looked down at her, at her so very pretty face.

"The gentleman also appreciates it if you look up into his eyes, so he can see how much you love giving him this intimate pleasure, and so that he can see, as well as feel, his hard member within the sweetness of your mouth."

Marilyn briefly squeezed her eyes shut in resistance, in defiance, but then turned her head back and up, and opened her large, pretty eyes.

Her look was more of a puppy dog distress than affection, but that made it all the more beguiling. Alex turned to the professor. "Dr. Hirschfeld, I really don't think I can last much longer."

"That's very, very good, Alex. We look forward to your ejaculation."

Marilyn's eyes widened in shock and fright. She turned as well to Dr. Hirschfeld, the head of Alex's cock still embedded within her mouth, albeit her tongue on temporary hiatus. "Hmmpph," she exclaimed, trying to get Dr. Hirschfeld to appreciate the gravity of the situation, but he was lost within his lecture.

"Now, pay attention students and watch closely. The orgasm is actually quite complex but doesn't last long. The rhythmic contractions occur initially at approximately .8 second intervals, and this accounts for the spurting action of the semen during ejaculation."

Alex's cock popped out of Marilyn's mouth. She asked, "Spurting, Dr. Hirschfeld?"

Dr. Hirschfeld had quite a bit of preparatory information to cover before Alex's ejaculation. He could not be bothered with her concerns right now. He waved at her to continue with the exercise. "The intervals between contractions become longer and the intensity tapers off after the first three or four. Semen usually takes a few seconds to appear after the feeling of ejaculatory inevitability because of the distance the seminal fluid has to travel." This next part he said in response to Mary Beth's earlier question, but also to reassure Marilyn. "During ejaculation, the sphincter of the urinary bladder is tightly sealed to keep urine from mixing with the semen, as well as making sure that the fluid travels outward. So, rest assured, Marilyn, you will not receive Alex's urine, just his thick, rich, fertile gruel."

That was enough. Marilyn pulled her face back off his cock and said, "Dr. Hirschfeld, do I really have to take it in my mouth?"

"Oh my, certainly not, Marilyn. It's entirely up to you. You can take it in your mouth or on your face. Either way will be fine. Boys will appreciate either one. No, wait, let me be fair about this. If you wish, you can also have him ejaculate onto your breasts. Although, you might want to remove your brassiere for that. I'm not sure you will want to get all that wet cum on your brassiere." Marilyn was tempted to thank him, sarcastically, for that consideration. "So, which would you prefer?"

Marilyn would prefer none of the above but apparently that wasn't an option. She opted for inside her mouth. The head of his penis really wasn't tasting that bad. Perhaps the semen wouldn't taste bad either, and it would certainly be considerably more humiliating to have him squirt all over her face or her breasts. If she took him in her mouth she would at least be able to hide the sight of his cumming from the rest of the class. From outside appearance, it would look no different than what she was already doing.

She didn't provide a verbal answer though to Dr. Hirschfeld. She spoke with her mouth as she once again absorbed the head of Alex's cock inside. She resumed her licking of the head, tickling the sensitive membranes with her soft, wet, feminine tongue, at the same time drawing her fist up and down the shaft, this time with more urgency and effort. She felt that if this was going to happen, let it happen soon so that she could get it over with.

"Now, that's the enthusiasm we like to see," Dr. Hirschfeld said with approval. It was good to see the models truly enjoying the experience. He had been a little apprehensive, particularly with regard to Marilyn. But, he could now see that she was actually enjoying herself. "Apparently, once a young lady has her lips wrapped around the shaft of a hard cock, her feminine instincts just take over."

Many of the girls in class blushed at the remark, as boys turned to look at them, wondering if it was really true and whether it might in fact be true for that pretty girl sitting next to him.

Alex gasped, "Marilyn, here it is."

Marilyn squeezed her eyes shut in abject disquietude and grimaced with disgust as she felt the first hot wad of gism splash against the roof of her mouth. She felt so ashamed, receiving his sticky gruel gushing into her mouth.

Dr. Hirschfeld though was quite pleased with the demonstration. "Yes, excellent, as you can see class, Alex is now releasing his sperm into Marilyn's mouth. Pay careful attention to the twitching of his shaft, the evidence of the contractions."

Jim was paying very close attention. He knew that some girls would be willing to do that: let a guy cum in her mouth. But, he seriously doubted that a girl would ever let him do it. This was pretty much as close he would probably ever get to it, and it was a pretty amazing sight.

Marilyn did not want her mouth to fill up with his stuff. It wasn't really distasteful. It didn't actually taste so bad. She in fact liked a lot of salt on her food. But, it was emotionally distasteful and she didn't want to finish this experience with a mouth full of cum. So, she opened her throat to swallow some down but just as she did so, Alex shot a third thick wad directly into her throat, and Marilyn instinctively gagged and lurched, rudely discharging the cock head from her mouth.

As Marilyn coughed and hacked, trying to dislodge the thick gruel from her throat, Alex released another shot that smacked right on her forehead.

"Mmmph!" Marilyn tried to protest, her eyes clamped shut with humiliation, one hand at her throat, trying to massage the cum down, the other swinging up to protect her face, but to no avail. Alex continued to spray the remaining jets onto her cheeks, her nose, and one even splatted on a closed eye.

Becky breathed a sight of relief at the sight of Marilyn's face being covered in gism. That could have been her.

"Marilyn, outstanding!" exclaimed Dr. Hirschfeld. "I thought you had chosen the mouth when in fact you're taking it both ways. Really outstanding. Quite a trooper! Now, class notice the amount of Alex's ejaculate. There are a surprising 20 million sperm per milliliter of seminal fluid, and the average ejaculation ranges from 1.5 to 5 milliliters, although I think Alex appears to be releasing an above average load" as Alex continued to splash Marilyn's face, as well the palm of her left hand. She was able to catch some of it. "Girls, you will be happy to know that semen contains quite a bit of nutritious material. There is aboutonia, ascorbic acid, blood_group antigens." All of the class was quickly writing this down. They would much rather watch Alex finish his deposits but they knew full well that much of this could be on the test, and they had to get it down.

"Calcium, chlorine, cholesterol, choline, citric acid, creatine, deoxyribonucleic acid, fructose, glutathione, hyaluronidase."

By now Alex had finished but he was still breathing hard and his legs felt weak. That had probably been one of his more intense orgasms.

Marilyn groaned with revulsion. She knew she must be quite a sight: sitting back on her haunches, her face littered with a boy's cum. She had managed to swallow down much of the cum within her mouth and she now used her right hand to try to clean off the wad that had lodged in the corner of her eye.

"Inositol, lactic acid, magnesium, nitrogen, phosphorus, potassium, purine, pyrimidine, pyruvic acid."

This was surely not what her parents had in mind when they had sent her off to college. Marilyn hoped that they would never find out about it. There was no way they would though. She certainly wouldn't tell them about it. Actually, she was more worried about her friends finding out. They would likely tease her to death about it. "Could I have a towel, please?" she meekly asked, both hands now held way out to her side, themselves dripping with cum. One drop slid off her cheek and onto to her brassiere. "Eeeuuuw" she softly moaned. Maybe she should have taken off her bra.

"Sodium, sorbitol, spermidine, spermine, urea, uric acid, vitamin B12, and zinc."

Now that he had finished his list, Dr. Hirschfeld pulled a sanitary wipe from a box on his desk. "Here, dear, let me help you with this," and he began to carefully clean and dab her face.

This was certainly considerate of him, but Marilyn wished that he would just gave her a handkerchief so that she could wipe it all off with one swoop. In addition, his cleaning her face was rather infantilizing. She felt like a little girl, getting her face all cleaned up by her daddy.

Dr. Hirschfeld continued his lecture. "Yes, quite a bit of nutrition girls." He added, "Marilyn, would you like to lick some of it off of your fingers?" as if the spillage had been ice cream.

"No, no, thank you sir," Marilyn replied. "Just, please, get me cleaned up."

"The nutrients though are all in very modest quantities. You really couldn't survive on it." He was correct about that, but it didn't seem particularly modest to Marilyn.

"Some of this is designed to nourish the semen on its way to the egg, while other ingredients are designed to neutralize the acidic environment of the vagina, which would normally be actually rather inhospitable to sperm. There, there, I think that is most of it." Dr. Hirschfeld handed the wipe to Marilyn so that she could finish the job.

She snatched it from his hand and more thoroughly cleaned her eye and the rest of her face, not wanting to leave any of it behind, although it was a rather small wipe and was by now itself thoroughly soaked with Alex's cum. She then took care of her hands, as best she could.

"For you girls on a diet though, an average ejaculation contains about 15 calories." He chuckled at his little joke. "Yes, Marilyn, that was really quite wonderful. Now, class, let's turn our attention to the female genitalia." Marilyn looked up at Dr. Hirschfeld, her right eye still a little squinty. Hadn't she just done enough? Apparently not.

"Marilyn, if you please."

"Sir?"

"Up off your knees and down with your panties, Marilyn. Hut, hut!"

If the purpose of this punishment was to develop some empathy for the embarrassment experienced by Michael, it was a complete, total, unmitigated success. She never before felt so mortified in her life, and yet it seemed like it was only just going to get worse, although how much worse could it be than to have a classroom full of students watch a guy unload his gism on your face?

Marilyn got up off the floor. Dr. Hirschfeld at least helped her with that. She handed him the soaked sanitary wipe, which he dropped into the wastebasket by the desk. She stood facing the class and slipped her thumbs into the waist band of her pink panties, although turning her flushed and stained face away from the gawking eyes of the students. She bent over at the hip and slid her panties down to her ankles.

She could feel a coolness on her bottom as her fanny was exposed to the classroom air. The temperature was clearly set for persons who were dressed, not for persons baring their fannies. She was at least glad that her bottom was facing the blackboard and not toward the students. But, now she had to stand up, and let everyone, even the boys, see her naked cunnie. She took a deep breath and did as she was required.

The boys wanted to applaud as her cunnie came into view. For some, it was the sexiest thing they had ever seen. For those who had already been treated with the sight of their girlfriends' pussies, it was a very close second. Marilyn had a very pretty pussy. The hair was quite sparse. Just a delicate, even elegant sprinkling that complimented rather than hid her feminine charm. The delicious lips that traversed the virginal mound of soft white flesh were clearly exposed.

Even Dr. Hirschfeld admired its appearance. "Oh my, Marilyn, yes indeed, that's a very, very nice little vagina." Marilyn blushed at the compliment. She didn't really know how to respond. The natural, the appropriate, response would be to say 'thank you, sir.' She had always graciously expressed her appreciation when complimented on her looks or her appearance. But, she didn't really feel grateful for this compliment. In fact, she would prefer that he would not say anything at all about it. However, it was much better than a look of disappointment. Imagine how embarrassing it would have been if Dr. Hirschfeld had pointed out that it was a rather unusually appearing vagina: too fleshy, or too hairy. That would certainly have been much worse. She responded, "Thank you, sir," with a modicum of gratitude, but not looking him in the eye. She looked bashfully toward the floor.

"Excellent, really fine. Now, Marilyn, why don't you get up on the table."

"Sir?" What was he going to have her do?

"Dr. Hirschfeld!" Johnny exclaimed, his hand waving in the air.

"Yes, yes, Jonathan, what is it?" Dr. Hirschfeld replied, feeling a bit impatient. He was beginning to worry about time.

"Her titties, her titties. Marilyn hasn't shown us her titties."

"Her breasts, young man," Dr. Hirshfeld corrected him. "They are her breasts." But, Jonathan was indeed correct. In his impatience and desire to get to Marilyn's vagina, he had neglected her breasts. "Yes, certainly, we mustn't forget the young lady's bosoms. If you wouldn't mind, Marilyn, the brassiere as well."

"Yes sir," Marilyn glumly replied. Her face deepened in color and her breasts inadvertently thrust out as she reached behind her to unclasp her brassiere. She felt little more than a stripper at a gentleman's club. She grimaced at the thought of such a club. 'Why would they call it a gentleman's club?' She couldn't imagine any actual gentleman attending such a club. Well, at least the young men in this class will have to behave like gentlemen.

She looked around the room. Many of the girls had their eyes averted, feeling embarrassed for Marilyn. Many also instinctively crossed their legs, as if their own cunnies were somehow being exposed in sympathy with the presence of the exposed lips of Marilyn. Becky gave her a smile of encouragement.

The boys eyes were largely split. Some were staring at her cunnie, others were waiting gleefully for what was to be revealed beneath Marilyn's pink brassiere, and most were shifting their attention back and forth. A few had their hands "resting in their laps," surreptitiously, lightly rubbing, their hard-ons.

Marilyn let the brassiere fall from her breasts.

The class was greeted with such a lovely sight. Marilyn had quite delicious breasts. As noted earlier, they were not large, but their shape was delectable. These were truly ripe apples, just waiting to be plucked. They stood up so proudly, despite the interests of their owner in preferring that they keep hidden from view. And, it didn't help that her nipples were fully erect. She blamed it on the cool air of the classroom, but many of the students, including some of the girls, wondered if she was actually becoming aroused. Their eyes shifted briefly to her cunnie. A few of the students swore that they could detect some glistening moisture.

"Marilyn, if you wouldn't mind, why don't you work your way along the desks and offer your breasts, briefly of course, to each of the boys. I would like each of them to get a good sense of the textural quality of a young woman's breasts."

Could this get any worse? She really had no idea that she had agreed to all of this when she had opted for the modeling over suspension. She kept saying to herself, 'It's better than being suspended, it's better than being suspended, it's better than being suspended,' as she traversed the curved line of desks, bending over in front of each so that the boy could briefly fondle her.

A few of the boys were not the least bit shy, grabbing hold quite firmly, copping a major squeeze. What self-respecting, alive, boy would turn down the opportunity to feel some naked boobies? Particularly ones as gorgeous as these. They were so terribly round, soft, and firm, and the nipples were so hard and pointy. None of them though said anything disrespectful. They knew how and why Alex and Marilyn were modeling for the class, and they were not about to make the same mistake, although a few of the boys didn't really feel that Alex was that bad off. A bit of humiliation might be worth the experience of having a pretty girl such as Marilyn suck on your cock.

She couldn't look them in the eye as she offered herself, or more accurately, her tits, to each one of the guys. She felt like she was leaning out over a fruit cart as various male customers tested the shape, firmness, and ripeness of her fruit. Imagine telling your mother about this class exercise when you come home for Thanksgiving!

Some of the boys though seemed to be just about as uncomfortable as Marilyn. Actually, that wasn't really true. Nobody was as uncomfortable as her. But, some of them were rather tentative and felt terribly awkward about taking advantage of the situation. Marilyn almost didn't mind their touch. They were at least being sympathetic and respectful of her. James in fact just lightly touched her, and only for a moment, drawing his fingers away at the shock of the feel of a girl's naked tit.

"Now, Jimmy," Dr. Hirschfeld admonished him. "You're not going to learn anything if you're not willing to engage the subject at hand."

"Yes sir," he replied. He softly whispered an apology to Marilyn as he reached out once again. Marilyn felt bad for him. Here was the one guy who was being the most respectful, and he is the one who is being apologetic. Marilyn smiled at him, cupped her breasts in her hand, and said, "Go ahead, Jimmy, it's okay."

He smiled back at her. Before this day he had only seen pictures of naked tits. Now, Marilyn was actually offering hers to his touch. He reached out and lightly felt, caressed, the tender curves and slopes of Marilyn's bubbies. They felt like his baby sister's little bare butt: so soft, so smooth, so white.

His traveling fingers eventually reached her nipples. These were particularly amazing. He couldn't believe how far they stuck out, and how sexy they felt to his touch.




Modeling for the Class



Dr. Hirschfeld spoke up. "Yes, Jimmy, carefully explore her nipples." Jim was quite glad to do so. Jonathan was annoyed. He was the one who suggested Marilyn take off her bra. He should be the one to explore the nipples. "A nipple, or mammary papilla." They all reverted to taking notes again, with, of course, the exception of Jimmy. He wasn't hardly even listening. He was just softly tracing his fingers around and around Marilyn's perky nipples, entranced at the sight of their erect state. "The nipple is a small projection of skin containing the outlets for 15 to 20 lactiferous ducts arranged cylindrically around the tip. The skin of the succulent nipple is rich in a supply of special nerves that are sensitive to certain stimuli. The physiological purpose of nipples, of course, is to deliver infant milk. Marilyn, why don't you demonstrate."

Marilyn would normally have become quite upset at the suggestion. However, her nipples were feeling quite aroused, and Jimmy was such an innocent, harmless boy. She leaned over further. The boys directly behind her, across the empty space of the classroom, were disappointed in being blocked from view, but they were then offered a quite reasonable alternative, the backside of her cunnie pouch poking into view; such a nice sweet slit.

Jimmy leaned up, out of his desk chair, pursed his lips, and grasped hold of Marilyn's nipple. He began to suckle like a little infant. The room was filled with the sound of the suckling boy.

Dr. Hirschfeld observed, "Mammalian infants have a rooting instinct for seeking the nipple, and a sucking instinct for extracting milk. This instinct seems to be alive and well in Jimmy." He was taking to the task like a baby to the teat. Marilyn was surprised that she didn't actually mind. His lips did feel nice on her nips, and he was such a safe, non-threatening boy. She even reached out and stroked his hair as he suckled. He looked so innocently content, as did she strangely feel. Although, it wasn't an innocent feeling that was developing between her thighs.

"Of course, sexual stimulation can also cause the nipples to become erect, due to the release of the polypeptide neurotransmitter oxytocin." None of the boys would object to the idea that sucking on a girl's tit could make you high, but that really wasn't what Dr. Hirschfeld was saying.

"Oxytocin is released during orgasm in both sexes," his voice having some difficulty competing with the sound of Jimmy's suckling. Marilyn's bottom began to squirm a bit, much to the pleasure of the boys behind her behind. "In fact, it is believed that oxytocin is involved in social recognition and bonding, and might be an important chemical in the formation of trust between people." Marilyn was beginning to feel quite a bit of trust for Jimmy as he was "bonding" with her.

Dr. Hirschfeld, though, noticed their excited states, as well as the fact that time was running short. "Yes, well, let's move on. Marilyn, please, release your teat from the young man and climb up onto the desk."

A little popping sound could actually be heard as Marilyn wrested her nipple from Jimmy's lips. She turned toward the table, her wet nipple glistening in the harsh light of the room. She would normally have balked at what she knew was coming next, but at the moment she was in a bit of a fog, apparently lost in a cloud of oxytocin.

She walked in a daze to Dr. Hirschfeld's desk. She had enough self-awareness to try to protect her modesty as best she could as she hopped onto the desk, mostly by keeping her legs together and her bottom right on the desk. It was a really futile effort though. Her breasts jiggled and wiggled as she hopped backward onto the desk.

"Alright then, Marilyn, lie back down on the desk and spread your legs out to the edges on either side, just like when you visit your gynecologist."

The realization of how exposed she was hit her hard with that remark, and she had to cover her face with her hands in embarrassment. This did not feel like a doctor's visit, although even some of those were rather awkward, particularly with a male physician or, even worse, a young, handsome one. No, this just seemed simply and frankly obscene. She was actually sitting on the desk of a classroom, spreading her legs for all the students to see her cunnie.

A few of the desk chairs could be heard squeaking as a couple of the male students inched forward a bit. The boys toward the front and side of the room could actually see very little. Alan raised his hand. "Dr. Hirschfeld?"

"Yes, Alan, what is it?"

"Sir, we really can't see very well over here."

"Oh yes, certainly, that is a problem. Hmmm." He contemplated what to do. He could have them stand around in front of Marilyn, but that would block the view of the girls. However, that might not be bad, as they should already be quite familiar with the anatomy of the vagina. But, still, you can never underestimate the lack of preparation some students have received from their parents regarding human sexual functioning. The girls should be allowed to see the demonstration. "Yes, well, why don't you boys come up here and sit on the floor in front of the desk."

They eagerly agreed, in fact scrambling to get into the front row.

"Be sure to bring your notepads," Dr. Hirschfeld reminded them. It was a good suggestion, as very few of them were planning on doing that. It was like they were back in the third grade and the teacher was going to read a story to the class. Everyone wanted to get a good spot. There was pushing, shoving, whispering, and pointing, particularly a pointing from within their trousers. Some of the girls rolled their eyes at their childish enthusiasm. A few of them also noticed the evident bulges within their slacks, despite the best efforts of the boys to hide or disguise them. The sight of the protruding slacks brought on a few giggles of their own, as well as some disapproving scowls.

Marilyn blushed at the sound of the boys scrambling in position to get a good luck at her exposed cunnie. She at first appreciated the new class seating, for when she opened her eyes she no longer saw a row of eager boy eyes staring between her legs. However, when she looked down (she had to at least see where they were), she felt even worse. They were all sitting on the floor, cross-legged, their eyes wide in delight and anticipation, like they were waiting for her to put on a show for them, which was precisely what she was about to do.

Alex started to sit down in front of Marilyn himself, but Dr. Hirschfeld corrected him. "No, no, Alex, why don't you stand off to the side here. We might have further need for you." Alex frowned. He was hoping that he was entirely finished and, besides, sitting down on the floor would go far in hiding much of his nudity.

The other boys, however, were not at all disappointed. There was something a bit awkward for them, to be sitting next to a naked guy, particularly as they were really crowding in close, to Marilyn and, as a result, to each other. Alex got back up and stood off to the side of the desk, his hands now covering himself. Susie, who was sitting nearest to him, smiled at his embarrassed modesty.

When everyone seemed to be in position, Dr. Hirschfeld resumed his lecture.

"Alright boys, settle down," Dr. Hirschfeld scolded. "Now, class, first, it's important to emphasize that the term 'vagina' is often used inaccurately to refer to the entire female genitalia. Strictly speaking, the vagina is the elastic muscular canal projecting inside. Fortunately for you guys, it isn't really very large, only about 4 inches deep. A good two inches shorter than the average erect penis." The boys were quite relieved to hear that (although he didn't point out during intercourse the cervix and fornix can shift to provide more room). "The vulva consists of the exterior female genitalia." The boys wrote that down, but they did so with quite poor penmanship, as they no longer had their desks and they were trying to keep their eyes on Marilyn's vagina, or vulva. "The vulva includes this lovely soft mound of fatty tissue covering the pubic bone, called the mons pubis, or more elegantly, the mons veneris or 'mound of Venus.'"

Dr. Hirschfeld circled his finger around and around Marilyn's soft mound. Marilyn softly sighed, her pelvis instinctively twitching with an unsettling nervous excitement.

"Wait, wait," complained Jimmy, trying to get it all down. He really didn't want to miss anything here. He felt it could someday prove to be rather important.

Dr. Hirschfeld smiled approvingly at the seriousness and conscientiousness with which James was approaching this lecture. He waited for him to catch up. "Now, the outer, large lips, are the labia majora, which is much of what you see here with Marilyn." He ran his fingers along Marilyn's lips, as she turned her head in abject shame. She was still quite excited from the suckling of Jimmy and hoped so much that it was not apparent to the boys, but the touch of a man's finger on her cunnie was not helping. "She really doesn't though have a striking or strong labia minora, the inner lips." Dr. Hirschfeld slid a finger up and down her slit. Dr. Hirschfeld noticed the moisture. "Some men find it preferable for the female to have quite large, evident, protruding labia minora, whereas others prefer this more simple, innocent, crevice."

Marilyn pleaded with him. "Dr. Hirschfeld, please." She had played with herself quite a number of times, but no man's finger had ever touched her there before. Well, her gynecologist certainly had done so, but this was really quite different. Perhaps if she had not given herself over to Jimmy's suckling, but, no matter the full reason, she knew her arousal was not going away; if anything, it was getting worse. Her breathing began to accelerate.

"Now Marilyn," Dr. Hirschfeld reassured her, "Your vulva is really quite pretty, I must say. I imagine many of the girls here would love to have one so attractive." He turned to one of the girls. "Don't you think so, Patty?"

Patty looked up with considerable fright as all of the heads of the boys turned to her. She really didn't know what she should say right now, other than to ask Dr. Hirschfeld to please call on someone else. "Um, yes, well." She squeezed her thighs together, not wanting to provide any suggestion that she would like some sort of a comparison.

Dr. Hirschfeld then used the index fingers of his two hands to carefully spread the lips of Marilyn. "Now, here, toward the bottom, is the opening of the vagina." This was extremely important information for many of the boys. Most had assumed that it would be right in the middle of the slit. "In females who have not engaged in penetrative sex, the opening of the vagina is sometimes partly covered by a membrane called the hymen." All of the boys knew about that. "Let's take a close look here." Marilyn noticeably squirmed in embarrassment. "No, no, I don't see one here. Marilyn, have you already had sexual intercourse?"

Marilyn quietly whispered through her hands. "No sir, no, really, I haven't."

Dr. Hirschfeld smiled knowingly. "Yes, well, the hymen may indeed rupture spontaneously during exercise, or in some cases." He bent down to look real close inside. "It can be so minor as to not be noticeable." He felt around with one finger of his right hand as he kept the slit open with the fingers of his left hand. Marilyn was whimpering with confusion and concern. "No, no, I really don't detect any sign of it. "Bobby, why don't you step up here and see if you can notice any suggestion of Marilyn's hymen." Robert almost leaped from the floor.

"Sir, really, that's not necessary. I don't have one."

"Well, yes, of course." Dr. Hirschfeld would have preferred that Robert look anyway. He wanted the students to gain some first hand knowledge of vaginal anatomy, but Marilyn did have a point.

Robert was sorely disappointed. "Nuts," he exclaimed, as he sat back down.

Some of the girls giggled at his discontent, as well as the sight of him adjusting the position of his cock as he sat back down. 'Serves him right,' Alice thought.

"Now boys, as I draw my fingers down along the perineum, which in many persons is quite sensitive." It certainly was for Marilyn. "You can also see nicely, particularly from your vantage point, Marilyn's anus." Dr. Hirschfeld used his finger to draw their attention to Marilyn's puckered hole. He lightly circled his finger around and around the tightly wrinkled brown star.

"Oh my gosh," Marilyn softly exclaimed, squinting her eyes tightly shut in the hope of being able to control herself. This was so terribly humiliating, having so many boys staring at her anus as it was being caressed by a man, but she could not deny the excitement that was building within her. And, she knew that some of her increasing arousal was due precisely to the fact that she was exposing herself in such a terribly indecent manner, spreading her legs for boys so that they could look at her puckered asshole.

"How many of you girls have engaged in anal intercourse?"

Toni started to raise her hand but quickly pulled it back down when she realized that she would be the only one, or at least the only one who was willing to admit to it. Most of the girls simply blushed at the thought.

"Dr. Hirschfeld," Becky exclaimed, "isn't that a perversion?"

"No, no, dear," Dr. Hirschfeld responded, still lightly exploring the folds and wrinkles of Marilyn's anus. Marilyn's butt squirmed at the tickling. "No sexual act, by itself, is a perversion. Perhaps if you become overly preoccupied with one particular pleasure, that might constitute a problem, but, no, my dear, anal intercourse can be pleasurable for both the inserting and the receptive partners. The anus has quite a high concentration of nerve endings and for many girls, and boys, a very pleasurable erogenous zone."

Marilyn knew, firsthand, what he was saying, but she was not about to admit it, at least not verbally.

"It's important though to be well lubricated before entry." And, right on cue, a large, glistening drop of feminine dew formed at the base of her Marilyn's lips and slid down her perineum to her anus. "Well, thank you, Marilyn," Dr. Hirschfeld exclaimed.

"Students, slightly below and to the left and right of the vaginal opening are two Bartholin glands. When the female is sexually aroused she produces lubrication which can allow for sexual stimulation and/or penetration." Dr. Hirschfeld asked, as he worked her feminine fluid into her puckered star, giving it a nicely appealing glistening twinkle, "Marilyn, do you yourself enjoy anal sex?"

Marilyn crushed her hands against her face and shook her head back and forth. But, what the upper part of her body denied the lower seemed to betray.

Dr. Hirschfeld pushed, shoved the tip of his thick, manly index finger past her sphincter and into her rectum.

Marilyn lurched with the shameful intrusion and clamped her sphincter tight, trying to deny any further entrance. His finger felt so big in there and it was terribly humiliating, but she knew, she had to admit, at least to herself, that the next time she diddled herself, she was going to try sticking one of her own fingers up inside there. "Please sir," she whispered. "This is so embarrassing."

"My goodness, boys, she has quite the grip on my finger," but he slid his finger deeper inside, and then began to softly move it in and out, at the same time caressing her sensitive anus with his thumb. Marilyn's bottom squirmed on the table, her head moving back and forth, trying to deny what she was feeling.

"Sir?" Robert asked, his hand raised, "Can I see what it feels like?" He wasn't going to give up.

His request brought Dr. Hirschfeld's mind back to the task at hand. He could not dilly dally here too long, as there was still much to cover. He brought his finger out of her rectum with a nice little pop.

He cleaned his finger with another fresh sanitary wipe. "Marilyn, if you wouldn't mind, would you now please open up your vagina for the class? That will be most helpful."

Marilyn hesitated, quite understandably. It was bad enough when Dr. Hirschfeld parted her lips, but now he wanted her to do it herself, as if she was some cheep slut who wanted to show everybody the inside of her cunt?

"Please dear, we are becoming a bit short on time. There will be another class coming in here soon."

Marilyn certainly didn't want to be laying back on the desk, her legs spread, as another group of students walked in. But, it was good news to hear that the class would soon be over. She recalled as a child waiting on the last day of class, watching the hand of the clock slowly work its way to the time when the bell would go off. She never wanted so much for a class to end. She slowly removed her hands from her scarlet face and reached down, grasping her lips with her index fingers, and parted them open for the class to look inside.

The boys gasped with delight, the girls with disconcertion. Marilyn had seen girls posing like this on the internet. She would have to admit to that, but she considered it to be one of the most sluttiest, obscene things to do. She even cringed at the sight of a girl doing that, and yet, here she was, herself, spreading her lips for the boys.

"Oh, that's excellent, my dear. Now, boys, you can clearly see her vaginal opening, and notice how wet and moist she now is. Marilyn is developing quite a state of sexual arousal," as were all of the boys, some of whom were squirming themselves, trying to hide their stiff dicks, or find a more comfortable position, perhaps one in which they could quietly, surreptitiously, play with themselves.

Alex was himself getting aroused again. He could quite openly use his own hands on himself and in a sense he was, but largely to just try to hide his evident excitement from the girls. Susie though could clearly see his problem and she motioned to Becky, sitting next to her, to notice it as well. However, none of the girls needed to be alerted. As the boys' eyes were fixed on Marilyn's cunnie, the girls' eyes were watching the return of Alex's erection.

Dr. Hirschfeld brought his finger back to Marilyn's exposed, wet cunt. "Just above the vaginal opening is Marilyn's urethral opening and, further up, of course," his fingers drawing up moisture as he moved up her parted slit, "one of the more important parts of the vulva, Marilyn's clitoris."

Marilyn loudly gasped at the touch of Dr. Hirschfeld's finger on her clit. She was very, very sensitive there.

"Yes, boys, its sole function in the human female is to induce sexual arousal." He softly caressed the engorged nub. "The only known exception to this is perhaps the Spotted Hyena, where the urogenital system is modified so that the female urinates, mates and gives birth via an enlarged, erectile clitoris, known as a pseudo_penis."

"Eeeeeuuuw" many of the boys, and the girls, exclaimed. That didn't sound terribly appealing to any of them.

"Now, well, Marilyn, you can let go now."

Marilyn happily did so. One could almost hear the wet lips smack shut. It was done. There couldn't be any more. The class was over.

"Now, boys, just as the girls were provided the opportunity to explore the aroused male sexual organ, I want each of you to have a turn doing the same with Marilyn. "James, if you please. The rest of you can take a brief turn after him."

The boys scrambled to get into line, with considerable jostling and pushing. Even Dr. Hirschfeld was squeezed away. "Now, boys, no shoving. Behave yourselves or I will have Marilyn get dressed and nobody will have a chance to finger her." That threat settled them down.

Jimmy tentatively reached out, his index finger extended, and carefully laid the tip of his finger on Marilyn's aroused clit. Marilyn released a soft squeal, of both shame and wanton lust. Jimmy pressed down and slowly circled his finger around and around. Marilyn spread her thighs open even wider, her hips responding in kind to his tender, sensual, touch.
