Sex-Ed Demonstration
--------------------


Part 1: Sex-Ed in School


Darren was nervous. This was quite understandable considering what the day
had in store for him. Silently the sixteen year old cursed himself for
getting himself into this. It was all Tony Baker's fault. Tony had been the
first volunteer for the new "Physical Development Demonstration Project"
and claimed it had been the "easiest twenty quid he'd ever made."

The PDD project, as it was more often called, was a part of the latest
government initiative to improve the standard of sexual education in
schools. Darren's school was taking part in a pilot scheme, which if
successful would be extended to the whole country. The idea of the scheme
was to ensure that young boys and girls approaching adolescence were fully
informed of the changes that would occur in their bodies as they went
through puberty. Consequently volunteers were sought from amongst the older
boys and girls in the school to act as models to show what the body looked
like after these changes.  The lessons were to be conducted entirely
separately for boys and girls; older boys would model for younger boys and
older girls would model for younger girls. Also, the lesson would be given
by a teacher of the appropriate sex. The rules for the selection of models
were extremely clear. All volunteers were to be of 16 or 17 years of age
and were required to undergo a physical examination to determine their
suitability for the scheme. Since only a limited number of models were
required, the teacher who would be conducting the lesson would also attend
the physical examinations in order to make his or her selection. Successful
volunteers would be paid the token sum of twenty pounds for their services
and each model could only be used on once.

Darren had actually only signed up for the project to save face. Tony had
made such a big deal about it, waving around his cheque for twenty pounds
like a trophy, saying how easy it all was and that only a real wimp would
be too scared to volunteer for it. The result had been a large crowd of
boys invading the school office in order to sign up to be the next
model. Though Darren suspected that most of them were not really that
interested in the money, they were really there, like himself, to prove
that if Tony Baker wasn't afraid to do it then neither were they.

Within a couple of days, most of the boys were given a letter thanking them
for applying but saying they had not been selected. Darren had received a
different letter, telling him he had made the short list of four and would
be required to attend a medical examination the following day.

The medical examination had been extremely embarrassing. First Darren had
had to strip completely naked, then almost every inch of his body had been
poked and probed by the male doctor. All of this was observed by
Mr. Jackson,. Darren's biology teacher, who stood quietly attentive, just
off to the side. It was Mr. Jackson who would be conducting the lesson and
who had the final decision as to the selection of the model.

What had made matters worse was that Mr. Jackson was hot. Seriously
hot. The young teacher had only started at the school at the beginning of
the previous term. He was in his early twenties and this was his first
teaching post, and his comparatively youthful good looks combined with an
athletic build had made him an instant target of adoration amongst many of
the girls at the school. Many of the girls and at least one boy. And that
boy just happened to be Darren.

Over the past couple of months, many of Darren's fantasies had involved his
biology teacher. At first, this had surprised the sixteen year
old. Previously he had always been attracted to boys of his own age or
younger, but there was something about the teacher that he could not put
into words, something that night after night had him pumping on his hard
meat as he imagined the older man's hands on his body.

The examination had seemed to go on forever, and Darren had kept his eyes
straight ahead, deliberately avoiding looking at his teacher, trying not to
think about his private fantasies. At last the doctor had pronounced the
examination finished and told the boy he could get dressed. As quickly as
he could, Darren had pulled on his clothes and hurried out of the
room. There were plenty of male teachers in the biology department, why did
it have to have been Mr. Jackson?

He'd never been a religious boy, but that night Darren had prayed that he
wouldn't be the one selected to be the model. He'd promised god that he
would never have erotic thoughts about his teacher again if only this small
wish would be granted. However, laying in his bed his mind began to drift
over the events of the day. As he replayed the medical examination his hand
strayed down to his groin. Mr. Jackson had seen him naked and watched as
the doctor had examined his cock and balls. Before he knew what he was
doing he was pumping furiously at his erection and minutes later he lay
panting, a sheen of sweat coating his body and a small pool of sticky,
white cum on his stomach.

The next morning he had been summoned to Mr. Jackson's office. The teacher
smiled as the boy entered and waved his hand towards a chair to indicate
that Darren should sit. It appeared that god had not been at all impressed
by the teenager's promises. Darren was the one selected to be the next
model. For the next few minutes, Mr. Jackson gave brief explanation of what
would happen in the lesson. Darren hadn't been really listening, instead
he'd been asking himself over and over why he had signed up for this in the
first place. Though thinking back on it later he found he could remember
most of what was going to happen. He would be naked throughout. The teacher
would need to touch him, including touching his penis and scrotum. It was
expected that he would become erect at some stage during the lesson, though
if he couldn't become erect for any reason he shouldn't worry. Hopefully,
if he did become erect he would also agree to ejaculate and samples of his
semen would be collected so that the younger boys could observe his sperm
under a microscope. The boys in the class would be allowed to get close to
him, but not to actually touch him.

At the end of the explanation, the teacher had paused and asked Darren if
he was sure he wanted to go ahead. The boy had considered his options. He
could agree to do what would probably be the most embarrassing thing in his
life, something that made him squirm even to consider it, or he could just
say no and let them find someone else. "No problem, count me in," he had
said, and he had managed to sound convincing even to himself.

Now the day of the ordeal had arrived. Darren briefly considered if he
should pretend to be ill, but he quickly dismissed the idea. If he backed
out at this stage, Tony and his friends from school would never let him
live it down. Tony had spent the past few days bragging about how much cum
he had managed to produce during his demonstration, and taking bets that
Darren wouldn't even be able to get hard, never mind shoot. In spite of the
sick feeling in his stomach, Darren was determined not to give Tony the
satisfaction of seeing him chicken out. He'd not "masturbated" for two
days, as suggested in the written instruction he had been given, and he'd
had an especially thorough shower. He was as ready as he would ever be.

He really didn't feel like breakfast, but just to keep his mother happy he
managed to force down most of a slice of toast, then grabbing his school
bag he set off out of the door.

"Hey, wait for me."

With a sigh, Darren paused to allow his twelve year old brother to catch
up. "Why do I always seem to be waiting around for you?" The older boy
asked.

"Could be 'cos your legs are longer so you walk faster than I do," Kevin
replied, a little short of breath from rushing.

Darren shook his head. One day he would catch his brother without a smart
answer. The two boys usually walked to school together. In fact, in spite
of the four year age difference between them they did most things together,
rarely even having the kind of squabbles that were usually common amongst
brothers. Today though, Darren had things on his mind and wasn't feeling
particularly sociable, so he walked along in silence paying little
attention to his brother's chatter.

For his part, Kevin appeared not to notice Darren's silence, he was quite
capable of keeping a conversation going entirely on his own. This morning
he appeared especially excited about something.

"What was that?" Darren stopped dead in his tracks. Something Kevin had
said had just registered in the back of his brain.

The younger boy also came to a halt and gave his brother a worried
look. "You're acting strange this morning," he said, proving that he had
after all noted Darren's reflective mood. "Are you sure you're ok?"

"I'm fine," Darren replied, waving aside his brother's concerns. He'd not
mentioned anything about today to any of his family, and would prefer it if
none of them found out. "What was it you were just saying."

"I was telling you about the special lesson we were going to have today,"
said Kevin, his eyes sparkling. "It's our class' turn for the special sex
education lesson, this PDD thing. Today we get to see one of the older boys
naked. We'll see his willy and everything. Mr. Jackson says that if we're
lucky we might get to see him with an erection and maybe even ejaculate his
sperm." He grinned, showing off that he had been able to remember some of
the proper words for what was going to happen. "I can't wait," he added,
excitedly. "It's going to be mega!"

Darren's feet were rooted to the spot. This was something he had not
anticipated. His own brother was going to be there to watch him strip
naked, get hard and shoot off. For a long moment he felt sick. Then the
sickness eased to be replaced by a different feeling. He realised that
whilst he was still scared shitless by what he was going to do, he also
found the idea that Kevin would be watching quite exciting. It had been
years since the boys had seen each other naked, probably not since they
used to bathe together when Darren was about ten years old and Kevin only
six. Now that was about to change. Darren felt his cock twitch in his pants
at the thought. He wondered what Kevin's reaction would be when he found
out he it was his older brother's willy he would be seeing.

"Hey, you're not about to throw up or anything, are you?" Kevin asked,
stepping back just in case. "You've gone all pale."

"Really, I'm fine. My stomach's just a bit upset this morning. Must be
something I ate." Darren took some deep breaths to calm himself and the two
boys finished their journey to school.

The DPP was scheduled for 11 o'clock, so Darren had to attend normal
lessons for the first two hours. The time really seemed to drag, and the
constant stream of comments and jokes coming from Tony and the other boys
in the class didn't help.

"Don't know why they picked Darren," said Tony, at one point, in a loud
stage whisper which carried throughout the entire classroom. "I thought the
idea was to show the little kids what a MAN looks like." A titter of
laughter swept around the class.

Miss Newton, the teacher taking the class glared at Tony. "From what I
hear, Mr. Baker, after seeing your own demonstration the poor boys were
left with the impression that their sexual organs were actually going to
shrink as they got older." The titter of laughter turned into a gale and
blushing red, Tony suddenly appeared to find the book in front of him
extremely interesting. "It's almost time, Darren." The teacher gave the
sixteen year old a sympathetic smile. "Why not go and get yourself ready?"

With a grateful nod, Darren gathered his books together and hurried out.

Pausing to dump his books in his locker, the nervous teenager made his way
to the biology room. Up some stairs. Around a corner. Along a corridor. He
was there, at the door of the room. This was it. He could still back out,
he kept telling himself. What was a bit of ribbing from his friends? He
could cope with that. He didn't have to stand naked and let the younger
boys inspect his body. He sure didn't have to let Mr. Jackson handle his
cock and balls; Mr. Jackson, the subject of so many of his night time
fantasies. Before he had chance to change his mind he raised his hand and
knocked on the door.

"Come in." Mr. Jackson's voice game faintly from inside the room. Darren
tried to put on a confident smile, turned the handle and entered.

"Ah, Darren. Right on time," smiled the teacher. "Boys, this is Darren and
he has very kindly volunteered to be our model for this demonstration
session."

Darren gazed around at the assembled faces. There were only a dozen boys in
the room and so it took just a second for him to locate his
brother. Kevin's face was a picture of shocked disbelief.

"How are you feeling, Darren?" The teacher asked, speaking softly so that
only the sixteen year old could hear. "A little nervous, I expect."

"Yeah, just a little," Darren admitted, understating the truth by a mile.

"Don't worry. You'll feel better once we get started. I only realised this
morning that your brother is in this class, are you ok with that?"

"Yeah, no problem."

"Good, then we'll make a start. Are you wearing briefs or boxers?"

"It said on the sheet you gave me that it would be better to wear briefs,
so that's what I put on."

"Good boy. While you strip down to your briefs, I'll get your audience
warmed up."

"Most of them looked warmed up already," observed Darren, glancing around
at the eager young faces. Even Kevin had now recovered from his earlier
surprise and looked like he couldn't wait for the show to start.

"I think you may be right," laughed Mr. Jackson. "I wish they were this
enthusiastic about all of my lessons."

As Darren turned his back and began pulling off his clothes, Mr. Jackson
spoke to the class. "I know most of you are excited about what you are
going to see today, but I want you all to be on your best behaviour. It's
very good of Darren to agree to do this for us, I'm sure he's very nervous;
just imagine how you would feel if your were asked to take your clothes off
in front of an audience. Anyone who fails to treat Darren with the respect
he deserves or who gets too out of hand will be straight out of the door,
no arguments. Do you all understand me."

There was a subdued chorus of "Yes, Mr. Jackson."

"Good, now the warnings are out of the way, I want you all to enjoy this
lesson and hopefully you will also learn something. As we proceed if any of
you have any question or have anything useful to share with the rest of the
class, please speak out. Now, if Darren is ready..."

Darren was indeed ready, clad only in a pair of dark blue briefs which
suddenly felt two sizes too small, he stood with his arms folded across his
chest facing his audience. At Mr. Jackson's suggestion he moved to stand in
front of the teachers desk.

"If you would all like to move in a little closer, we'll begin." Under the
teacher's supervision, the boys all moved forwards forming two rows. The
front row, seated on chairs were hardly more than a couple of feet from
Darren, so close that if they put out their hands they would be able to
touch him. Behind them the other boys were sitting on desks so that they
could see over the heads of the ones in front. There had been a bit of a
scuffle to decide who got chairs and who got desks, it seemed everyone
wanted a front row seat. Kevin in particular looked disappointed that he
had ended up on the back row.

"I think that we're ready at last," said the teacher. He opened his mouth
to continue, but one of the boys from the back row interrupted.

"Sir, he's still got his underpants on. I thought he was going to take
everything off."

"Patience, Jonathan. Patience," the teacher replied, impatiently. "The
purpose of today's lesson is to give you an idea of the changes you can
expect to see in your bodies over the next few years. We have not gone to
all the trouble of setting this up merely so that you, Jonathan, can stare
at Darren's penis. Don't worry, Darren will remove his briefs shortly and
then you will get to see everything, but until then please listen and just
maybe you might learn something."

Jonathan fell silent at the rebuke and also received a sharp jabs in the
ribs from a smirking Kevin, who was seated on the desk, next to him.

"Before we ask Darren to finish undressing," Mr. Jackson began, "let's take
a good look at his body as a whole. Think for a moment about how Darren's
body is different from your own." He paused for a moment and looked around
expectantly.

"He's bigger than we are," suggested a boy from the front row.

"Of course he is, stupid, he's older," sneered Jonathan, from the back.

"Actually, Jonathan, Martin's observation was a good one," said the
teacher. "Unless you can think of anything constructive to say then I'd
rather not hear your voice again this lesson. Any more ideas?" He asked,
speaking to all of the boys.

"He's got more muscles," one boy called out.

"Not quite true, Tom," smiled the teacher. "He has the same number of
muscles as you and I, but I know what you mean and it was a good point to
make. As you enter puberty, amongst the changes you can expect to see are a
faster rate of growth upwards and, if this is accompanied by adequate
exercise, a corresponding development in your musculature. This doesn't
occur at the same time or in the same way in all boys. Some of you will
seem shoot up in height and will perhaps broaden out later, in others it
may be the other way around. One of the reasons Darren was chosen as
today's demonstration model is because of his excellent proportions. Notice
his nicely defined pectoral muscles." He moved up close and put an arm
around the Darren's shoulders, placing the palm of his other hand flat
against the boy's chest.

Darren, who had been trying to pretend he was somewhere else and not to
think about what was happening, was taken by surprise by the action and
flinched visibly.

"I think your hands must be cold, sir," one of the boys laughed and the
others briefly joined in.

"Sorry, Darren," the teacher apologised, then made a show of blowing on his
hands to warm them up.

"No, it's fine," The sixteen year old said, quickly. "I just wasn't
expecting it."

"Oh, I see," Mr. Jackson smiled. He once more put his hand on to Darren's
chest. "As I was saying, Darren has a very nice, well defined shape. Good
pectorals and a firm stomach." Here he lowered his hand to press against
the boy's stomach muscles. "It's very important that, especially at this
stage in your development that you get plenty of exercise and that you eat
healthily." He paused for a second and stepped back. "You may have noticed
another important difference between Darren and yourselves, when he spoke a
moment ago. You will have noticed that his voice was deeper than your
own. Some of you will experience this change very quickly, in others it may
take a considerable time, again it varies from person to person. Are there
any questions so far?" He looked expectantly around the semicircle of
faces, but no one spoke.

"Good, then I think we are ready to move onto the next stage. Would you
like to remove your briefs please, Darren?"

Darren was almost tempted to say, "No, I wouldn't like to do that." But
he'd come this far, he may as well get it over with. In a single, quick
motion he pushed down his briefs and stepped out of them, dropping them
onto the desk behind him. His hands moved automatically to cover himself
and it was only with a great effort of will that he kept them by his
side. Nervously he shifted his feet around and tried to avoid looking at
any of the boys, but his gaze was drawn to Kevin. His brother, like all of
the other boys had his eyes glued to Darren's groin area, then, just for a
moment, he looked up and gave Darren a warm, encouraging smile and a
"thumbs up" sign before returning his attention downwards again.

But it seemed that not everyone was so encouraging. From the boy, Jonathan,
sitting at the back next to Kevin came a soft snigger.

"What are you laughing at, jerk?" Kevin spoke up, his eyes flashing fire.

"I dunno," replied Jonathan, "it's too small for me to make out what it
is. Arghh! You prick!" He let out a squeal of pain as Kevin's fist caught
him in the ribs. There followed a short but violent scuffle as both boys
began to rain punches on each other.

"That's enough!" Mr. Jackson's bellow echoed around the classroom. A
deathly silence descended. "Come here, the pair of you." Eyes downcast,
Kevin and Jonathan moved forwards. Their teacher observed them, coldly. "I
will not have behaviour like that in my classroom. It would be bad enough
at any other time. But imagine for a moment how Darren must feel. He's been
gracious enough to agree to do this demonstration for us and in return he
had to watch that little spectacle. Jonathan, I heard those comments you
made, you've just earned yourself a week of detentions. Now get out of my
sight, go and stand outside the headmaster's study. I'll be along when this
lesson is finished and we'll see what Mr. Baxter has to say about your
behaviour, he may like to add some punishment of his own." As Jonathan
left, Mr. Jackson turned his attentions to the other boy. "However
justified you feel your actions were, Kevin, I can't condone fighting in
class like that. I'm sorry but I'm going to ask you to stand outside in the
corridor for the rest of the lesson."

Kevin was obviously mortified at the decision. "But sir...".

"That's enough, Kevin. I'm not going to argue with you. One more word and
you'll be joining Jonathan in detention."

Red faced with anger and disappointment, Kevin followed his teacher's
instructions and left the room.

"I'm sorry about all of that, Darren," said Mr. Jackson as the door
closed. "I hope you are still willing to continue?"

The past few moments had seemed almost surreal to Darren. He shook his head
as if to wake up from a dream. In a way he felt responsible for Kevin being
sent out, after all, the boy had been defending his big brother. He briefly
considered asking Mr. Jackson to let Kevin back in, but quickly dismissed
the idea; the teacher had already made his decision and would stand by
it. "Yes," he said, eventually. "I'm ready to carry on."

"Good, then lets pick up where we left off." The man was immediately all
calmness and smiles, as if the last few minutes hadn't happened. "Would you
put your hands up behind your head, please Darren. Thank you. Now boys,
there is a reason I've asked our model to raise his arms. If you look
carefully at his armpits, you will see there are a few strands of
hair. There's not much there at the moment, but there will probably be much
more as Darren grows older. The armpits are just one of the places where
hair will grow. I'm sure you've all noticed the hair around Darren's
penis."

The boy tried to think of other things, determined not to blush as
attention was once more directed at his groin area.

"You were probably all already aware that hair grows around the penis, but
did you know that hair grows around the back as well? If you will please
turn around, Darren and bend over the desk."

This time Darren really did blush. As he leaned over the desk, Mr. Jackson
placed a hand on each arse cheek and pulled them apart, exposing the arse
to the room.

"As you can see", the teacher explained, "there is also a little hair
around Darren's anus. As with his armpits, this will probably get thicker
as he gets older. Thank you Darren. Would you turn around again please?"

Still blushing, Darren once more faced forwards. He hadn't expected that
even his arse-hole would be receiving a thorough inspection.

Mr. Jackson either ignored or appeared not to notice his models
embarrassment. "As well as the areas we've looked at, hair will also grow
in many other places, such as on your face, arms and legs, and in many
cases on your chests and even sometimes on your backs."

"Jeez, we're gonna look like gorillas," one boy observed, pulling a face.

"Don't worry, Paul, it's not quite as bad as that," Mr. Jackson reassured
him. "Some people are naturally hairier than others. If you do grow hair
and don't like it you can always shave it off."

"I don't fancy the idea of shaving my bum," the boy called Paul joked.

"Funnily enough, Paul," observed the teacher, "I don't much care for the
idea of shaving your bottom either." This last remark caused a round of
laughter.

Even Darren smiled at the teachers little joke. Though he was thinking to
himself that Paul was really quite a cute kid and if he ever did want
anything shaving, Darren might just be willing to volunteer for the job. It
took him a couple of seconds to realise that this was the first time he had
thought about any of the boys in a remotely sexual way and he quickly
decided that given his current situation, perhaps such thoughts were best
avoided. He also noticed that he no longer felt quite so uncomfortable
about being nude in front of the youngsters. Though he was still along way
from actually enjoying being on display.

The teacher had pulled up a chair and placing it at Darren's side he sat
down on it. "Could you open your legs a little wider, Darren?" He said
placing a hand on the boy's thigh.

Darren took slow, deep breaths through his nose and tried to calm his
nerves. The man who had so often formed a part of his recent fantasies was
about to touch him in the most intimate way possible. None of his fantasies
had ever been anything like this.

"We're now going to have a closer look at Darren's penis and testicles,"
announced Mr. Jackson. "As you can see, his penis is in its soft state at
the moment. While it's like this it's completely flexible." He lightly took
hold of the boy's cock and moved it around to demonstrate just how flexible
it was. "Notice the skin covering the top can be pulled back, like so." He
pulled back Darren's foreskin to reveal the dark pink glans beneath. "This
skin is called a foreskin. Some boys have it removed shortly after they are
born, they are said to have been circumcised. As you can see, Darren still
has his foreskin intact. If, like Darren, you have not been circumcised
it's very important that you pull your foreskin back regularly and wash
underneath it. If you don't do this the head of your penis may become
infected and this can result in some potentially serious problems. That
doesn't mean to say that boy's who are not circumcised should be any less
scrupulous when it comes to personal hygiene."

A tingle, like a mild electric shock had passed through Darren's body as
the man took hold of his penis. It felt good. In spite of the surroundings,
the audience of watching preteen boys, his own nervousness at the
situation, it felt very good. He held his bottom lip between his teeth as
his foreskin was retracted and he knew it wouldn't take much more touching
before he started to get hard. He risked a glance at the watching boys, but
none of them met his gaze, their attention was directed lower down. Quite a
few of them were cute, he decided. He wondered if any of them were gay and
were getting turned on by what they were watching; from the way they were
sitting it was impossible to tell.

The teacher had finished his short lecture on hygiene and had turned his
attention to Darren's balls, though of course he referred to them as
testicles, pointing how they hung down below the body to keep them at a
lower temperature and that generally loose clothing was better than tight
clothing. He cupped the teenagers balls briefly in the palm of his hand
then gently rolled them between his fingers.

With an effort, Darren suppressed a groan. He was definitely getting turned
on by this, a fact that wasn't missed by the teacher.

"Notice how the attention it has been receiving has caused Darren's penis
to start grow." He once again took hold of Darren's cock, this time more
firmly. "Watch how it becomes hard as I rub it, and as it gets hard it
becomes longer and thicker. Don't worry if you can't see properly, I'll rub
it a few more time then I'll take my hand away so you can all get a good
look."

Darren's cock was now fully hard, pointing upwards and outwards, twitching
up and down as everyone's eyes focussed on it.

"Wow! It's enormous," one of the boy's observed, causing Darren to once
more blush.

The teacher laughed. "Not really enormous. It's perhaps just a little
bigger than average size for his age, though I'm sure Darren appreciates
the compliment."

"Does that mean he's gay, sir?"

"I'm not sure I follow you, Andrew. Having a slightly larger than average
penis does not make a boy gay."

"No," Andrew replied, "I didn't mean that. You're a man, and when you
touched him, he got a boner. If being touched by a man gives him a boner,
doesn't that make him gay?"

Darren inwardly cringed at the question, frightened that his secret was
about to be revealed. But he needn't have worried, Mr. Jackson came to his
rescue.

"The penis is a strange organ," the teacher explained. "It's affected by
all sorts of things. If it receives enough stimulation the chances are that
it will become hard. The brain has no say in the matter, the penis goes its
own way. So to answer your question, Andrew, no it does not mean that
Darren is gay. In fact, I would be willing to bet that as a result of just
watching me stroking Darren's penis some you boys are sitting there at this
moment with your own penises hard."

A number of the boys had suddenly become very red faced and were shuffling
uncomfortably in their seats. One of them, Darren was pleased to note, was
Paul.

"I thought so," the teacher smiled. "It's a natural and healthy reaction to
what you have been watching and nothing at all to worry about. It doesn not
necessarily mean that you must be homosexual. Let's move on, shall we? Now
that you've had chance to see an erect penis I'm going to ask Darren if he
would be willing to let us watch him masturbate. Before I do, I want you
all to remember that whilst masturbation is perfectly normal and something
almost every man and boy does, it is also usually a very private and
personal thing. To do it under these circumstances, in front of other
people, takes a great deal of courage. Darren has already been extremely
courageous in allowing us to examine his body like we have, so I don't
expect any of you to think badly of him if he decides he does not want to
perform this final demonstration." From his seated position, he looked up
at the teenager. "I want you to know, Darren, that this next part is purely
optional. You've already earned your fee so you are now entitled to put
your clothes back on and leave if that is what you want to do. However, I'm
sure every one of these boys would be extremely grateful to you if you
would do this last thing for us."

Darren looked around the expectant faces. Some of the boys seemed to be
holding their breaths, waiting for him to say yes. The one called Paul was
even subconsciously nodding his head, willing him to agree to do it. He
quickly analysed his own feelings. He was still nervous, but it was a
different sort of nervousness from the sick feelings he had experienced
earlier. A small part of his mind even seemed to be enjoying the fact that
his body was on display to these youngsters, and that frightened him a
little. Did he want to wank himself in front of them? Before today, no one
had ever even seen him with an erection and here he was considering doing
the most personal thing a boy could do in front of an audience of eleven
and twelve year olds. "Ok," he said softly, a shy smile on his lips, "I'll
do it."

"Good boy," said Mr. Jackson, standing and putting his hand on Darren's
shoulder. "If you like you can sit on the front of my desk, that should
make it a little easier for you."

Darren nodded and stepping back, he took a seat on the edge of the edge of
the desk, as suggested. Deliberately he opened up his legs as wide as he
could to give the boys a clear view of his still erect cock and low hanging
balls; if he was going to do this thing he may as well do it
properly. Wrapping his fingers around his erection he began making slow,
deliberate strokes, up and down. He closed his eyes, shutting out his
audience and like so many times before, he tried created a scene in his
mind involving himself and his hot biology teacher, the man who minutes
earlier had stroked his cock to full hardness. Strangely though, on this
occasion the image refused to come, instead another picture kept
appearing. He kept seeing the face of one of the boy's in the class,
Paul. He wondered what the cute youngster would look like naked, and
wondered if he had ever sucked cock. Unlikely though it was that the twelve
year old had ever had done such a thing, he certainly did it that morning
in Darren's imagination. As he rhythmically stroked his rock hard penis,
the teenager undressed the younger boy in his mind, saw him, hard and
willing, bend forwards and place his beautiful, full lips over the swollen
head of Darren's throbbing boymeat, his young, inexperienced hands gently
kneading the older boy's balls. Darren saw his own hand moving around to
caress the soft curved flesh of the boy's arse cheeks, saw his fingers
slide between the velvety mounds, deep into the slightly damp crack, felt
his middle finger press firmly and insistently against the boy's tight,
virgin arse, heard the muffled gasp forced out from around a mouthful of
hard prick. Darren was now pumping wildly on his cock, his breathing loud
and ragged. Lost in his own private world of pleasure, he was completely
oblivious to the wide eyed youngsters sitting mere feet away. His hips
began to raise up off the desk, thrusting forwards in time with his jerking
wrist, his breathing became even more erratic and he knew he was nearly
there.

"Oooohhh, fuck!" He gave a long, drawn out groan, as streamers of white cum
erupted from his dick. He tried to keep the rhythm going in an effort to
hold onto that brief, fleeting moment of ultimate pleasure, but it was not
to be. Exhausted, he fell back onto the desk, is eyes still closed.

Moments later, he opened his eyes and looked around. In front of him, stood
Mr. Jackson, a small, flat class dish in his hand on which were some drops
of whitish fluid.

"Managed to get some of it," the teacher smiled. "Though you took me a bit
by surprise, it was like mount Vesuvius erupting for a moment there. Most
of the stuff went straight over the dish. Looks like Andrew caught some of
it."

On the front row, one of the boys was grimacing down at the glistening
string of fluid on his trouser leg.

Darren was unable to keep his face straight. "I wonder if his mother will
believe his explanation of how he got cum stains on his trousers."

The teacher frowned good-naturedly. "I think you mean semen stains,
Darren. Your language became a bit colourful for a moment there, though I
suppose I can overlook it, given the circumstances."

"Erm, yeah, sorry. I guess I forgot where I was."

"Don't worry about it," laughed the teacher. "There's some paper towels
behind you. Get yourself cleaned up and put your clothes back on."

Darren quickly dressed, watching the boys return to their own desks and
prepare for the next part of the lesson, in which the teen's sperm would be
put under a microscope. Mr. Jackson worked efficiently to get all the boys
organised, then returned to Darren.

"You did a great job there," the teacher said to the boy. "You're
definitely the best model we've had."

"I thought this was only the second time you'd had one of these classes,"
Darren observed.

"Well, it is," the teacher admitted. "But of the two you were by far the
best. I wish we didn't have this silly rule about not using the same model
again. If it weren't for that I'd certainly offer you the job next time."

"I'm not sure I'd want to go through that again," said Darren, with a
grimace.

"I somehow don't believe you mean that. You were obviously extremely
nervous to start with, but I honestly think that by the end you were
actually enjoying yourself. Anyway, your cheque is waiting for you in the
school office. My sincere thanks for doing this for us. That last part was
above and beyond what was expect of you and I promise it will be reflected
in your end of term report."

"Thanks," said Darren. "I guess I'd better be getting back to my normal
lessons."

"Unless you'd like to stay and help analyse your sperm," offered the
teacher.

"Erm, no thanks."

Mr. Jackson gave a short laugh. "Ok, you get off then. Oh, and as you go
out you'd better tell your brother he can come back in now. I really didn't
like sending him out like that, but I couldn't just ignore fighting in
class."

"I understand," said Darren, "but I'm not sure Kevin will."

It turned out that Darren was right, Kevin didn't. The older boy found his
brother standing silent and miserabe in the corridor. "Mr. Jackson says you
can go back in now."

"Big deal," muttered Kevin, not even trying to keep the bitterness from his
voice. "Not much point in going back in now, is there?"

Darren put a sympathetic hand on Kevin's shoulder, but the younger boy
shrugged it off.

"Just leave me alone," he said, and turning away, head down, he went back
into the classroom.

Darren felt bad, but there was nothing he could do. He felt guilty knowing
that Kevin had only been sent out because he was sticking up for his older
brother. He decided he talk to him about it after school and tell him just
how much he appreciated what the youngster had done, maybe that would make
him feel a little better.
