Summary
     "You're seeing her tonight, right? You need to practice it before
     that", Charlie said his eyebrows crunching and the side of his lips
     turning as he seemed to think something. Suddenly his eyes shot up
     and he kneeled up on Don's bed, grabbing his brother from the
     shoulders. "I know! I teach you! Like with the probability math two
     weeks ago".

"What is it Chuck?" Don asked, slightly irritated, glancing at his brother
through the mirror. He had already been nervous enough, the lock of hair that
he had been fixing the last five minutes being proof of that, and now this. His
little brother was fidgeting, leaning slightly to his door frame and those big
brown puppy eyes watching his every move behind the untamable whirl of curls.
It was unnerving. He didn't need this tonight.
Because tonight would be the night. He and Cara had their 6 month anniversary;
they were going to go to Dire Straits concert and after that to Cara's place,
since her parents were the night out. And he would be doing it the first time.
And he could admit it, he was nervous. The locker-room talk had already spread
the rumors that all the members of the baseball team had made homeruns outside
the field too. But the truth was that half of them hadn't ever even been on the
first base, and were only dreaming of the runs in the secluded privacy of their
own rooms.
So the last thing Don wanted to worry about was his little brother.
"Mmm... are you going out?" Charlie asked sounding both curious and apologizing
all the same time.
"Yeah. And you can’t come with me", Don said, maybe slightly harsher than was
necessary.
"Is it with that girl?" Charlie asked, the curiousness in his voice burying
everything under it.
"What girl?" Don asked, turning from the mirror to nail his brother with his
demanding look. People always started fidgeting for some reason when he looked
them that way, Charlie being no exception.
"That curly haired girl from school. The one you were kissing before math
class", Charlie said nervously, all though his eyes shine bright, the same way
they shine when somebody hinted they had an unsolved math problem for him to
try out.
Don's only answer was a low groan. His friends had often complained how it
sucks to have their little brothers and sisters attending the same high school
now that they were in senior year. He only rolled his eyes for them. Just try
guessing how he felt when his four years younger brother was attending the same
classes as he did.
"So... do you love her", Charlie asked nonchalantly but kept his curious eyes
fixed with Don's.
"I'm not going to start discussing my possible love's and not’s with you", Don
said and turned back to face with the mirror. It seemed Charlie didn't take the
hint but instead stepped from the door in to the room.
"Have you had sex with her?"
The comb that was going through Don's hair, stopped in midway.
"Have I... what?" Don was dumbfounded. This was supposed to be the night and
here was his baby brother starting a discussion of his sex life. He had had
enough. But before he could throw his brother out of his room Charlie once
again managed to throw Don's stance off.
"Cause I was told you are supposed to practice it before you do it with the one
you love".
Something in the way Charlie said that made Don itch but since he didn't know
what was it, he just blurted out the first thing that came to his mind.
"Oh, and who told you something like that?"
"Some girls from school..." Charlie said and lowered his eyes to his feet. Only
now Don realized Charlie wasn't wearing any socks. He almost told him to go put
ones on, but then an ominous thought crept through his spine.
"Did they offer to practice with you...?" Don asked carefully, not sure what he
wanted to hear.
"Yes!" Charlie screamed out, his eyes all shiny again and suddenly he spurted
past Don and jumped to sit cross-legged on his unmade bed. "You know, first I
didn't know what to think when they told me that. Cause didn't dad say you do
things like kissing and touching with the ones you like a lot. But they said I
would only hurt and disappoint my future girlfriend if I hadn't practiced at
all... so it all felt really weird. But now that you too say it's so, I don't
have to worry about it anymore".
Don just barely caught himself for blurting out that it was not okay and that
what those girls did was not only morally wrong but also almost illegal.
Instead he shut his mouth and sat beside his brother on the bed.
"So... who were the ones teaching you", Don asked nonchalantly, all though he
could already picture in his mind the talk he was going to have with these
teachers.
"I... I actually don't remember their names", Charlie said sheepishly. "But
they have the locker 275, 283, 340 and 531".
Don smiled and ruffed Charlie's wild locks a little; typical for him to not
remember the names but if it were the numbers, of course he remembered.
"What about you?" Charlie asked.
"Hmmmh?" Don voiced out. There were times he hoped he had been an only child
and then there were times like these; when curly locks tangled between his
fingers made him feel more relaxed and peaceful than anything else.
"Who have you practiced with?"
"Aaa~ no one actually", Don said and only when he saw the big wide yes of his
brother staring him in disbelief, he realized he had said that aloud.
"I mean... not wit-"
"You haven't practiced it! But you have a girlfriend! I don't even have one and
I've practiced it. How come you haven't?" Charlie asked little too loud and
even though his words weren't probably meant as mocking, Don couldn't help but
feel that way a little.
Because Charlie was right. For Charlie could be described as a nerd. Don had
even beat couple of the guys when he had heard them call him a freak. But still
he had managed to have sex four years earlier than Don. Don who had a hot
girlfriend and who was a promising part of the baseball team. What had a while
ago been protectiveness for his younger brother, suddenly turned to jealousy.
Don left Charlie's hair alone and moved slightly further from him. But Charlie
didn't notice this. One could only wonder how one could be so genius and in the
same time so oblivious.
"You're seeing her tonight, right? You need to practice it before that",
Charlie said his eyebrows crunching and the side of his lips turning as he
seemed to think something. Suddenly his eyes shot up and he kneeled up on Don's
bed, grabbing his brother from the shoulders. "I know! I teach you! Like with
the probability math two weeks ago".
It was Don's turn to stare the other with wide eyes. Did Charlie realize what
he was saying? Not to mention he just compared teaching math to teaching sex,
but it seemed he had all together forgotten that they were both guys... and
brothers on top of that.
It seemed Charlie was reading his mind with some weird filters on. Because
other way his next words would have not made any sense at all.
"It wouldn't be so weird since we are brothers right? We like each other...
right" Charlie asked hopefully.
"Sure we do... but still we cant-"
"But you have to! You can’t disappoint your girlfriend..."
"And you think you can teach me?" Don asked, trying to ignore the earlier
jealousy that he felt again rising. And even more the nagging voice somewhere
inside him that whispered that Charlie actually had a point in this practice-
idea of his.
"Of course. I'm a good teacher", Charlie said, pouting a little but before Don
could laugh that pout and this whole ridiculous idea off, Charlie suddenly
moved. And whatever Don had excepted, it wasn't feeling Charlie's tongue
thrusting in to his mouth.
Don grabbed Charlie by the shoulder, with every intention of pushing him away
and ending this madness. But his hands had a different idea and instead of
pushing away, they hugged him closer and he could feel Charlie inhaling sharply
under the crushing pressure. And that should have given him an opportunity to
end the kiss. Instead he sucked Charlie's tongue deeper still as his fingers
found the intriguing curly hairs on the nape of his neck.
When Don finally let go of Charlie's lips, it took a few seconds for them both
to catch some breath.
"Okay... I don't think you need... any practice with kissing", Charlie said out
of breath. His lips were swollen and there was a hint of blush on his cheek
which made him look more adorable than ever. And Don had never felt guiltier
than now. He was already rising up from the bed, making some space between him
and his brother since it seemed he could no longer control himself, when
Charlie's words froze him.
"I knew it. I knew it would feel better with you", Charlie said, his eyes
shining with amazement when he watched Don. And all though still feeling
guilty, Don was more curious than afraid to hear more so he stayed put.
"You know, with those girls... I didn't like any of it. The kissing was all
slimy and... just yuck. It really should be done with someone you like... I
don't think my practice with those girls were any good", Charlie said sounding
disappointed and defeated.
The slightly blushing image of Charlie mixed with the one now in front of Don;
eyes cast down and shoulders slouching. For some reason Don just couldn't take
it, so he pulled his brother to a hug.
"Then lets practice together", Don said. Charlie raised his hung up head
hopeful and Don realized he wasn't regretting his proposition as much as he
probably should have.
"Like you said, you already have some practice and I don't have any. And we
already like each other so why not", Don said and was probably convincing more
himself than Charlie.
Because Charlie didn't need any convincing. As soon as Don had voiced out the
together part, Charlie had once again locked his hands around Don's neck and
was now straddling on his lap. And Don could feel his arousing rising. Well he
was in his late teens and there had never been anything wrong with his libido.
But still, knowing what, no, who was pressing against him made him blush for
shame. Or at least he convinced it was because of shame that he was blushing.
But it seemed he was the only one feeling shameful for Charlie was there,
circling his fingers across the back of his neck and slightly rocking himself
against Don in his lap. And all that time Don could only wonder how in the
world Charlie knew how to act like this. He had barely hit the puberty and here
he was riding against him like he had been doing things like these for years.
And again Don could feel the jealousy rising.
Rising to his knees, Don pushed Charlie on his back. Because it was unfair that
his younger brother was sexually so much more experienced than he was, it was
only fair that he would use Charlie to practice a little. After all, this was
supposed to be the night. At least that was a better reasoning to his jealousy
as well as his actions than the one that somebody else than he had already done
these things to Charlie.
Don pushed the hem of Charlie's shirt upwards, revealing the pale, skinny body
under it. Don tried not to think how young his brother looked. This was
actually relatively easy since nothing in his actions indicated his real age.
Charlie's hands were already mapping his back muscles, traveling across his
spine and slightly caressing his sides. When they first brushed over his
nipples, his groin jolted happily, making Don push against Charlie.
Charlie inhaled sharply as he felt Don's swollen groin press against his and
all he could do was to grip Don's chest with his fingers and buck up as a small
moan escaped through his lips. It seemed this encouraged Don more since there
was another thrust and then he could feel his brother’s lips on his neck, on
his chin and finally kissing him again.
And Charlie felt relieved. He had already spend many nights wondering if there
was something terribly wrong with him, since he hadn't liked any of this with
those girls. But now he realized there was nothing wrong with him. Because he
loved his big brother more than anything; even more than math. And touching him
felt good. And being touched by him made him feel things he couldn't have even
imagined to feel. At least not while doing this; Charlie thought as he once
again met Don's thrust halfway through.
Don was slightly losing his control. Or the little there was left of it anyway.
Don left Charlie's lips alone as well as eased his grinding hips enough to pull
Charlie's shirt over his head. He could still feel Charlie's clothed groin
bucking against his stomach. And while his mind was still hesitating, his hands
weren't. They roamed from Charlie's chest to southward while he gained a
moaning gasp from Charlie when his lips found his small pink nipples. The cry
Charlie made was because Don's hand had traveled past the waist band and was
now stroking his still somewhat un-development shaft.
Don didn't dare to look Charlie's groin and acknowledge the undeniable proof
that showed Charlie was still way too young to do this. Instead he once again
moved up to meet Charlie's inviting mouth, just in time to catch the
disappointing moan Charlie made as his hand left his shaft. But Charlie's
disappointment didn't last long. It took a second or two for Don to slide both
of their pants down the necessary few inches and suddenly it all came to Don.
It would be in less than an hour that he would pick Cara up. And instead of
getting ready, he was practically fucking his little brother through the
mattress of his own bed. This was not right. He was using his brother naivety
to ease his own uncertainty. And still, knowing all this and feeling sick of
the very thought, the feel of Charlie's hands on the hollow of his back,
pulling him down, his mouth sucking his tongue and those narrow little hips
meeting eagerly his every thrust, pushed him through the edge.
Don could feel the stickiness of his own cum sliding against his groin for a
little while after he had already came. But eventually Charlie stopped rocking
under him and all Don could think of was that had he already had his first
ejaculations in Charlie's age. The thought of not, made Don feel sick. Screw
the four girls who had thought it would be fun to play doctor with the genius
kid. He was his brother and instead of protecting him, he was using him. And
now he had no idea what to do next.
"Come, let’s get cleaned before mom and dad come home", Don said and rise, too
much afraid to look at what he had done.

"So, Don, how do you feel about working with Charlie now?" The psychiatric
asked calmly.
"I just always feel like I'm taking advantage of him, you know, like I'm using
him or something", Don said and it all came out with such a rush that the words
were almost a blur. It was the first time he voiced out the guilt that made him
push himself away from his brother. And even still he was too afraid to look at
what he had done.
If he had, he had seen Charlie shaking his head in utterly surprise.
"Charlie?" The psychiatric asked, forcing the communication to continue.
"I love..." Charlie started slightly confused, unbelieving that Don had never
realized it. But as he saw Don turning to face him, fear and hope coloring his
features, Charlie got it and a relieved smile curved his lips slightly upward.
"... I love working with my brother".
