This is a vignette set in the Swiss College, an environment about and inside of which I propose to write more in the future. The dangling threads have been left intentionally so, in order to provide hooks for more vignettes and short stories. Still, I would like this text to be able to stand on its own. Since it is a vignette and not a short story, you should not really expect a plot. Just plenty of erotic tension. And a presentation. As you know, no contemporary human is allowed to spend a day without attending at least one presentation with boring slides. Luckily, our Miss Ross knows how to keep her classroom awake.

Thanks to everybody who read my previous story, Wrong Assumptions (http://www.bdsmlibrary.com/stories/story.php?storyid=8242). This one is set in a different world, but I am afraid that the style is not very different: sometimes I repeat myself but, as the Dixie Flatline said, "It's my nature."

------------------------------------------------------------

   It was a packed classroom, as Miss Ross could tell from the smell. Despite the windows, open on the lush garden that surrounds the school, the classroom still had a recognizable smell. Miss Ross inhaled discreetly as she got in - she liked the compound fragrance of so many young bodies. Personal hygiene was observed with great care at the school, but by the third hour of the morning classes the various exertions, activities, tests and devices had turned the fresh smells of the first hour (coffee, chalk, wax, after shave and occasional drops of perfume) into a deeply corporeal vapor, where the fresh marine note of adolescent pussy juice mingled with the deeper egg-white flavor of sperm and the occasional sharp smells of vinyl, rubber and leather.

   The twenty students, female, anything in between plus a few that defied classification were getting ready for the next class. The diligent ones were reviewing the pre-class reading material, while the very diligent did not need to, having already read and re-read them. The tardy students did not exist. The College was not built to tolerate tardiness or stupidity, and the teachers very rarely saw grades below 70%. Low grades always indicated a deeper problem and were investigated as deeply as a warning sign deserves.

   Education takes its toll, Miss Ross thought not for the first time. Education is exhertion, education is tough. But education is good, as she could tell by looking at the class. Her course on Sex Technology was optional for most students at the Swiss College, and mandatory for a few. Take little Jeanne in the first row, for example: she did not have a choice. As a matter of fact, Jeanne had very little choice in general, since she was being trained as a submissive. This morning, the girl had been ordered to wear a completely enclosing rubber body suit that left just her ears free. She would be a very attentive pupil, her focus enhanced by the sensorial isolation and by the fact that she had been strapped to her chair with broad leather straps. For the written test at the end of the day, her eyes and right hand were going to be left free. Miss Ross was not into unreasonable demands. Difficult demands, yes, sometimes very difficult, but not unreasonable.

   The classroom had been designed to look conservative but not stuffy. The walls were lined with display cabinets full of sex toys and devices. The wall farthest from the window was dedicated to Miss Ross' extensive collection of dildos and anal toys. In the center of the wall a special shelf had been set aside for the standardized penetration set: a collection of allergen free, hand-cast toys that were used in the education of most students. The toys ranged in size from diminutive training cocklets, the size of a lipstick tube, to true monsters, twenty inches long and four inches wide, bigger than a wine bottle. Some students claimed that the biggest toys were purely showpieces, decoration that had never been used. Wiser students reserved their judgement, particularly after a certain lesson during which Miss Ross had shown the correct application of a rubber horse cock. Quite a realistic one, the ponygirl had admitted afterwards.

   Other cabinets featured hundreds of instruments and curiosities and Miss Ross was always eager to demonstrate them for and on the few adventurous students who would still ask curious questions.

   Leaving the delightful Jeanne to stew in her suit, Miss Ross stood in front of the class, graciously accepted the mandatory greeting and invited everybody to sit down. A few of the pupils were wearing very high heels, and their relief was palpable.

   "Today we are going to start with a show and tell. As you might recall, during the last meeting we have discussed mechanical piercing devices, automated and manual, and I have promised you that we would return to the topic in a more hands-on way. Well, Sandra would you mind standing up and telling us about your project?"

  

   Sandra was a tall, thin girl with large breasts. This body type was quite frequent in the school, so she did not stand out as particularly remarkable. In her low voice, she started speaking what would probably be a long, boring piece.

  

   "Following instructions from Miss Ross, I have explored the topic of automated piercing devices. Automated piercing devices, also known as autopiercers, are machines that can execute a piercing without manual intervention. They are applied on the body, activated and left to proceed autonomously until the piercing is done. Autopiercers can do both play piercing, using thin needles that leave a small hole that will quickly close, or jewelry piercing, using a thicker needle that is usually followed by a piece of jewelry like a ring or a stud. The main types of autopiercers are: force controlled, position controlled, stochastic and feedback. It is claimed that the first completely automated piercing device was designed in 1975 in Los..."

   Miss Ross realized that this would not do. Sandra had a good memory and she could recite facts for hours. So she broke in brightly: "Thank you Sandra! I would appreciate it enormously if you could add some 'show' to your 'tell'. I suspect that your classmates would appreciate it, don't you agree?"

   The girl blushed deeply. Miss Ross' extreme and sardonic politeness was a indicator of imminent danger. Gracefully, Sandra opened her shirt, removed it and draped it over the back of her chair. A creased shirt would only earn her punishment. At the same time, being slow in undressing was a cardinal sin.

   The world of the Swiss College was filled with rules, and some rules combined to produce almost unsolvable situations. The pupils had to move quickly but harmoniously, they were supposed to display interest in their classes but not be too forward and obtrusive, they had to be sexually available but not too embarrassingly horny. The constant search for the right behavior could be very challenging, but luckily the trainers and the faculty were always eager to help, by pointing out what the wrong behavior was: or rather by communicating, through a dazzling array of punishment techniques, that a certain behavior had not been appreciated.

  

   Sandra straightened her back. She was wearing a white, clinical looking bra without any lace or decoration. "This is a special bra, designed to hold more securely the devices in position. I will now remove it for demonstration purposes, but only for a short time." She snapped open the front clasp and took off carefully her bra. Her nipples and her areolas were completely covered by two small black flat boxes, attached by some means to her skin. One box was marked by a yellow stripe, the other by a red one. Both boxes had a small blinking red LED.

  

   "This morning Dr. Marini, on request from Miss Ross, applied a set of autopiercers on me. They have been on since eight thirty. What you see on my left breast is a force controlled autopiercer, while on my right breast a position controlled autopiercer has been applied. Can I have the first slide, please?"

  

   Big Mike had the tendency to stop paying attention to presentations and drift off in erotic reveries all of his own. His long penis would stand to attention and his mind would be somewhere else. This is why Miss Ross enjoyed entrusting him with the remote that controlled presentations. For once, though, he was paying attention. Perhaps the sight of the small, innocent looking black boxes on Sandra's body had dragged his focus back to the classroom. He clicked the button and the first slide appeared, displaying two magnified mechanisms.

  

   "As you can see from this simplified sketch, there is a subtle difference. Both devices have a small motor and reduction gear that pushes the needle.

   The force controlled autopiercer exerts a growing force on the piercing needle. As soon as the flesh yields and the needle advances, the force drops to zero. The cycle is repeated as many times as it is needed until the needle reaches the receiving socket, which means that the nipple has been completely pierced. This would be the yellow-tagged one, on my left breast.

   On the other hand, the red-tagged position controlled autopiercer simply pushes the needle onwards at a constant speed, using whatever amount of force is necessary.

   In practice, this means that a position controlled autopiercer is predictable: piercing is completed over a precisely known number of minutes, hours or even days. The other type is less predictable."

  

   Sandra was holding up well to the pressure of having to present naked while feeling, all the time, needles greedily entering her flesh. Her voice did not falter as she asked for the next slide, that had graphs. "As you can see, the force exerted increases almost linearly..." Miss Ross once again stepped in: "I think that we would rather you tell us something more about what the piercers feel like."

  

   Sandra blushed enchantingly and looked at the class. "Well, the position controlled piercer is like an irresistible force. It just pushes the needle in. I can feel it advancing steadily. While the other one is more jerky, it feels like it is doing a real effort and the needle moves in a kind of slip-stick way." She knew that later she was going to be punished for being both too formal and too slack in her presentation. "kind of" was the type of expression that really made Miss Ross reach for an inflatable gag.

  

   Mike, displaying unusual alertness, asked about the other two types of autopiercers, the stochastic and feedback devices. He had clearly been paying attention from the beginning.

  

   Sandra bit her lip and started taking off her simple blue skirt and her white panties. The schoolgirl clothes worked well, Miss Ross thought, Sandra's master was right to insist on them as her everyday clothes. While the teacher's tastes run more to the exotic end of the spectrum, she could understand the simple appeal of well pressed cloth and very simple material almost without decoration.

  

   Sandra was now standing in her white knee socks and shoes in front of the class. The more fashion conscious students smiled but not too openly: Miss Ross had eagle eyes, and nobody in the class, particularly not the students that were training on the dominant side, could consider himself immune from her creative punishments.

  

   Sandra slightly opened her legs and pointed at her sex. "The box that you see here, hanging from my lab.. pussy lips" -it was so hard for her not to call them labia, but she had already been spanked a couple of times for that: Miss Ross took anatomical terms as a sign of priggishness- "this box tagged in green is a stochastical piercer. At every minute there is a given probability that it will pierce me - this is done with a simple random number generator. When the green LED blinks, it means that, for the next minute, I will not be pierced. When the next minute arrives, the dice is cast again. In the next slide... yes, this is a probability density graph, and I can also derive the likelihood that, at any given time today, I will have been pierced. Or not."

  

   "Sandra, I find it fascinating that you chose to start with that rather small and discreet device instead of the complex piece of apparatus that covers your pussy. I could even suspect you of being embarrassed."

  

   The girl took the hint and launched into her piece. "Yes, sorry, next slide please... This is the most complex piece of equipment I am wearing, and it is based on feedback. You can only see part of it, so I have borrowed an exact copy for demonstration purposes. As you can see, this large transparent pubic shield covers all of my pussy. It is convex and fits very well. The shield carries a small autopiercer, placed in the right position to pierce my clit hood. The long, blue probe with the egg shaped head at the end is actually inside my pussy: the probe contains a set of sensors that measure my temperature, wetness and muscular contractions. If my level of excitement or horniness drops below a certain threshold, the needle advances"

  

   Mike raised his hand, and so did little nerdy Luisa in the second row. Miss Ross nodded to Luisa who proceeded to point out that neither of the piercers installed inside Sandra's panties had any time guarantee. In principle, they could delay the piercing forever, if Sandra was lucky and horny enough. Miss Ross stopped the smart brat as soon as she brought up the binomial distribution. She had some free time this afternoon: Luisa was definitely going to get a spanking and a couple of forced orgasms, for her deliberate showing off of her advanced training in statistics.

  

   "Well, class, there is also something else: since Sandra is a masochist, every time the needle pokes her fat, juicy clitoris hood, her pussy becomes all moist and wet and pulsating, doesn't it darling, and the needle retracts. Oh, and the egg probe starts vibrating, as a reward. I think that this is happening right now. Perhaps standing up in front of the class does have some effect on that little tight pussy of yours. Now that you have told us about your project,  Sandra, will you please suck Mike's dick and then sit on it? I want to see his cock completely inside your ass in at most five minutes."

  

   Sandra was delightfully obedient. She kneeled on the floor and started sucking noisily on Mike's cock, trying to get it all soaked with saliva. She knew that he was not going to come easily, so she went crazy on his cockhead. Her tongue was dancing on the underside of his dick and her hands were playing with his balls. She prevented herself from getting lost in blowjob heaven and stood up, glancing at the classroom clock - still within the five minutes limit. Like most pupils at the Swiss College, in the morning she had received three enemas and a big syringe of thick lubricant - there was almost never a day without some form of sodomy and it was easier to assume that the students were always lubricated.

   Sandra's body was based on a recent pattern. Patterns incorporated a degree of randomness that made it difficult to tell, without detailed examinations, whether pupils belonged to the same pattern. New patterns were given grave thought by the Swiss College management, and most were rejected because it was felt that they were either small changes on existing ideas or ultimately unsustainable. The concept of "sustainability" when applied to the scheme of a human body and mind was a complex one, and it led to many intense board discussions. Sandra's pattern was not very extreme, anybody looking at her in the street would have just seen a beautiful if slightly shy young girl. The owners that chose this pattern were usually into discreet but intense pleasures.

   She looked Mike in the eyes, grabbed his cock and slowly sunk on it, the fat head dilating her anus and penetrating her. He pushed inside her; her ass had been specifically designed for pleasure, and it incorporated extra muscular rings, meant to multiply in time the feeling of the anus opening up. He moaned as ring after ring yielded to his blunt glans. This was like infinite fucking, he thought, and he was almost surprised when her butt came to rest on his thighs. He was completely inside her, and he could feel on the back of his cock the vibrations from the probe in her pussy. He helped her ride his penis. Sandra closed her eyes and placed her hands on Mike's shoulders, taking some of her weight on her arms. Mike realized that there was a reason why all the students with a penis were crazy about fucking Sandra in the ass.

   A body needed a mind to inhabit it. And of course, a disembodied mind is hardly a human mind - cognition and feeling are strongly dependant on a corporeal image. Sandra's mind (we could spend days describing it: normal to high intelligence, strong sexual drive, submissiveness, very little sense of humor, complete trustfulness plus thousands of other details) had been carefully designed around her owner's desires. Some of the design elements had been randomized, and some had been chosen by the designers for their own aesthetic reasons but, by and large, the College was convinced that Sandra and her owner were going to be very happy together.

   Sandra was completely focused on the fucking. Mike was kissing her aching breasts, while fucking her faster and faster. Miss Ross looked at her and called up the HUD that all faculty had access to. The HUD was able to read information from the environment and plaster it on top of her normal vision. It was an extra interface to everything, and the students did not have access to it. Even if she kept the HUD set to a low level of information density, the classroom blazed with information, and her body burned with a proportional amount of pain.

   She did not like the pain, but she admitted that it made sense: in order to prevent the teachers from becoming information junkies, sitting like huge panoptic spiders anywhere in the College, completely consumed with slicing and dicing tables of tables of numbers into exciting patterns and visualizations, a very simple rule made the information payable with pain. The more a teacher wanted to see at a given time, the more it hurt. More pixels, more bits, more ouch. Miss Ross was not a masochist, so she focused narrowly on Sandra. This brought the pain down to an almost unnoticeable level. The piercers were lazily sending out updates about their batteries and their needles' trip into Sandra's soft flesh. And, more importantly, the pussy probe signaled that, at the current rate, Sandra was going to come very hard in 90 plus/minus 10 seconds.

   Which suited Miss Ross perfectly fine. You never tell the whole story to a submissive, she thought. There always has to be a little twist left out, some element of surprise to refresh the basic concept: the submissive is never in control, and when he thinks he has understood the game, he has not. She called the attention of the class while switching off her HUD.

  

   "We are almost done for today. You two little fuckbunnies keep having your fun, and I am going to wind up the presentation for today, since Sandra clearly is not able to speak coherently right now. One important piece of information is that autopiercers can be configured as a network. In this case, they operate as a synchronized network of four units. This means that they will all fire at the same time, when the first one fires: Sandra is not going to have to wait. Lastly, I will also tell you that the probe in Sandra's pussy is programmed to fire whenever she gets too dry, but also if she gets too horny.

   In other words, if Sandra comes on Mike's cock, she gets pierced. In the nipples, clit and labia, all at once."

  

   Mike was not listening and Sandra was not either. She was riding up and down Mike's cock. Lubricant was oozing out of her ass, sliding down Mike's member and dripping off his balls on the floor. Some fragment of the last sentence appeared to have landed inside her consciousness, though, because she looked around with a curiously lost air. What could she do, anyway? Mike was in control now, and he was driving her towards mercilessly towards a hard orgasm. Her ass was now completely occupied, and she could feel him bottom out in her penultimate anal chamber. She was going to extract his sperm, she thought; she would suck it right out of his balls. And she was going to come - and be pierced if she had gotten it right. It was going to hurt like nothing else she had ever tried, Dr. Marini had warned her ... was she going to faint or just to scream?

   The class was staring, openly fascinated, at Sandra's movements. Mike was pumping her up and down rapidly, his hands on her hips, and his cock made squishing, slurping sounds as it travelled in and out of her ass. Luisa in particular was staring at Sandra's dominated pussy with a very fixed gaze. Miss Ross added interrogation and questioning to the list of things that she was going to do with her later.

   Sandra started moaning that she was going to come. Her voice raised in volume until her legs suddenly kicked out and she let out a scream; in the same moment a loud beep was herd followed by a mechanical snicking sound, recognizable in afterthought as metal entering flesh.

   She looked terribly startled and surprised. The fire burning her ass appeared to have spread to her nipples, her labia and her clit. What had happened? She realized that she had indeed been fucked hard and pierced, in front of the whole class. She started crying for the pain and the emotional release: she had not realized that she was so tense and worried for the coming piercing. It was much less bad than she had thought. She hugged Mike's shuddering body as he came inside her. She kept holding him and kissing his neck while Miss Ross spoke on.

  

   "Well, darling, it was not so bad after all. Here is your pass to go directly to Dr. Marini for aftercare and skip the next class. Everybody else, get going or you will be late for Athletics, and you know how picky Miss Bamberg is about punctuality. Luisa, meet me in my office after athletics." 

   Sandra was slowly getting dressed and recovering her wits. "There, there, don't look so shocked now. You did come, after all. Oh, and you are going to love your new jewelry, all gold and heavy gauge. That's the way your owner wants it."

   The class filed out, the ponygirls and ponyboys at the head, already quite nervous about the next hour. Mike was somewhere in the middle of the pack, still a bit dazed.

   The last pupil out was Jeanne who, packed in her isolation suit, was being led along by little Luisa strictly for entertainment and procedural value: when you are stuffed inside a heavy gauge rubber suit that barely lets you walk, Athletics is not going to be your day's high point. But no students were excused from the class, and anyway it would be good to be out there in the fresh air. And the sun. Shining brightly on black, heat absorbent rubber, thought Luisa, if I get her to sit in the right spot. She is going to be very hot and squishy, very grateful, she thought, very obedient. Luisa was not worried at all about her coming conversation and likely punishment at the hands of Miss Ross. Instead, she was looking forward to it, as more techniques to be learned.

   She pulled on Jeanne's leash and closed the door behind herself, leaving Miss Ross alone with her toys in the suddenly quiet room.
