Summary
     Finally the glances and the expression on Sam's face that morning
     made sense, and Dean found himself grinning as widely as the cat that
     got the cream. Okay, maybe not yet. But soon, sooner than he thought.

At first there were the stolen glances.
When Dean got up in the morning, when he came out of the shower, when they
sparred without their shirts on because fuck, that summer was hot.
Dean had never been shy, but feeling his teenage brother's eyes caress his
sweaty skin usually made goose bumps appear all over his back, and it wasn't
all that unpleasant.
Which is why he desperately tried not to think about it.
But how could he not, when his skinny little brother started morphing into -
that?
Sometimes Dean thought it had to be a curse, some kind of spell, because there
was no way Sam could have gone from gangly to bulky in just a couple of weeks.
His floppy hair, dangerous for the job if he listened to their dad, his hazel
cat-like eyes, and his ass where more than distracting.
God, Sam's ass was the most perfect thing Dean had ever set his eyes on, and he
could feel his mouth watering at the thought of biting, licking, tasting the
pale skin.
However, unlike Dean, Sam didn't like to be seen when he was undressed, so he
usually hid in the bathroom every time he had to change.
Maybe that's why it took so long for Dean to realize how hot his dorky baby
brother was becoming.
Despite all of Sam's efforts, though, Dean was good at getting what he wanted,
so after frustrating hours of stalking and sleepless nights, Dean had finally
succeeded in seeing Sam naked.
If he still had doubts about the fact that this physical attraction was only
due to the fact that there were no girls around and he was almost 20, just one
glance at Sam's lower body was enough for Dean to start imagining things so
dirty they had even him blushing slightly.
He had always been an ass man, so it shouldn't have come as a surprise to him
that all he could think about now was how to get Sam's perfectly shaped one
open under his mouth.

As we said, that summer was incredibly hot, and their dad had left them alone
to go take care of some evil creature on the other side of the country.
For the first time Dean hadn't payed attention to a single word his dad had
said to him, nor had he protested against being let on babysitting duties
again; all he had wanted was for their father to leave already, so that he
could execute his plan.
When their father wasn't around, Sam used to shuffle around wearing only a pair
of sweatpants, so short and old that there was nothing left to Dean's vivid
imagination, and Dean thought that if he had kept his eyes on the prize he
would be motivated to act faster - not that he actually needed that, but still.
No one ever refused eye candy, especially not Dean Winchester and especially
not when he needed to get laid.
  [http://i39.photobucket.com/albums/e187/marty_rurulove/GIFS/DividerWee.jpg]
For starters, Dean began to talk about sex with Sam.
All. The. Time.
Everything they did, everything Sam said was turned into some sort of sexual
innuendo; Dean had a great deal of anecdotes to tell, and if none came readily
to mind, hey, he was good enough to make one up.
Seeing Sam blush bright red up to the roots of his hair was quite a bonus.
  [http://i39.photobucket.com/albums/e187/marty_rurulove/GIFS/DividerWee.jpg]
"I think that jerking off is the gift of God to men" Dean stated, sitting on
his bed as Sam, laying on his own, was trying to read.
Sam huffed, already blushing, and crossed his legs as if to cover himself up.
Useless move, since he was just wearing a pair of boxers (too hot even for the
sweatpants, he said).
"Think about it" Dean went on "we have to put up with women, it only makes
sense for God to give us something in exchange for this hardship."
Sam muttered something that sounded like whatever and went back to his book.
"Have you ever tried it?" Dean asked abruptly, and Sam gasped, letting the book
fall.
"Wha-no!" Sam exclaimed, as his face turned purple.
Dean arched an eyebrow.
"Oh, come on, bro, you don't really expect me to think that you never spanked
the monkey, not once, since you found out what your dick is for!"
Sam fidgeted for a moment, but then his inability to lie won and he hanged his
head in shame.
"Fine, I have. Happy now?" he answered, sounding pissed, but Dean knew him well
enough to be sure that he was just embarrassed.
"There's nothing to be ashamed of, Sammy, it's natural, you know!"
Then, with a sly grin, he added "we should even do it together, sometime, you
know, to compare notes, or something."
Sam stared at him with his mouth hanging open, in shock, before grabbing the
book and storming out of the room.
"You're disgusting, Dean" he hissed as he walked past his older brother, but he
couldn't hide the spark of something in his eyes.
Dean saw it and mentally high-fived himself.
  [http://i39.photobucket.com/albums/e187/marty_rurulove/GIFS/DividerWee.jpg]
Once he had the confirmation that Sam did in fact jerk off, there was no more
peace for Dean.
He started spying on Sam almost obsessively, trying to catch him in the act,
and jerked himself off twice as much as he usually did just because the simple
thought of his little brother touching himself, his mouth slightly open and his
eyes at half mast got him hard in two seconds flat, and there was no cold
shower that could get rid of those erections, regardless of how many times he
came already or how sensitive his cock still was.
Dean felt like an Energizer bunny on Viagra, and even considered calling Bobby
to ask him if he thought it was normal.
He never got around to actually doing it, though, because every time he was
about to pick up the phone Sam would bounce in front of him wearing those
fucking sweatpants and he would get hard and distracted again.
  [http://i39.photobucket.com/albums/e187/marty_rurulove/GIFS/DividerWee.jpg]
There was a small lake next to the apartment his dad left them in, and Sam had
taken to the habit of going for a swim first thing in the morning.
Depending on how masochistic Dean felt, he stared at Sam as he put on his swim
trunks or kept his eyes as tightly closed as he could in order to avoid pushing
this situation too far.
He always tried not to jerk off in their room, because for as much as he wanted
Sam he never really wanted to make him uncomfortable; they were treading on a
very thin layer of ice, and if it broke at the wrong moment or in the wrong
place, they were never going to be able to come back from it.
Which is why Dean had to be careful.
That morning, however, all care went out the window when he woke up on the
couch instead of in his bed.
Dean vaguely recalled drinking in front of the TV, and concluded that he had
probably passed out.
He stretched, groaning loudly and popping his back and neck, all stiff because
of the position he had slept in, and it wasn't until he got up from the couch
that he saw Sam, standing still against their bedroom door.
His eyes were open wide and his pupils blown; he had his towel in his hands,
and Dean could see his fingers clenching and unclenching around it.
Sam's jaw was trembling.
Dean felt his neck burn, and he hoped with all his might that he was not
blushing, then greeted Sam good morning and walked to the kitchen.
His little brother followed him a couple of seconds later.
As Dean was turning the pancakes in the pan, Sam leaned in to take the
marmalade jar from the cupboard, and without intending to, probably, he pressed
his body flush against Dean's back.
That's when Dean felt it.
Sam's cock was poking him, and there was no chance in hell that was a gun; Sam
didn't carry guns in his pyjamas, that was for sure.
Sam was hard.
For him.
Finally the glances and the expression on Sam's face that morning made sense,
and Dean found himself grinning as widely as the cat that got the cream.
Okay, maybe not yet.
But soon, sooner than he thought.
  [http://i39.photobucket.com/albums/e187/marty_rurulove/GIFS/DividerWee.jpg]
Dean had done his best to act normal, and Sam didn't seem to notice anything
was wrong.
As soon as he left for the lake, Dean went back to their room, his palm pressed
against his aching cock and his mind filled with images of Sam and him.
Was Sam going to let Dean suck him? Was he going to give himself to Dean?
Dean had never even considered the idea of taking another guy's cock up his
ass, but damn, he was ready to try it, if that was what Sam wanted.
He just wanted Sam, in any possible way he could get him.
Before he could fully realize what he was doing, Dean had lain down on Sam's
bed and had thrust his hand down his boxers, imagining Sam's long fingers and
hot tongue mapping out his body.
He was so worked up and horny that it only took a couple of hard strokes for
him to come all over himself, his hand and Sam's sheets.
"Fuck!" Dean hissed, looking at the mess he had made.
He considered changing the sheets, almost a week had passed since they’d
arrived, anyway, and it wouldn't have seemed all that strange, but in the end
he decided against it.
He needed to shake things up, he needed to move forward; they didn't know when
their father was going to be back, and if they lost this chance who knew when
they were going to get another one.
  [http://i39.photobucket.com/albums/e187/marty_rurulove/GIFS/DividerWee.jpg]
Later that day, once Sam got back, Dean followed him into their room, wearing
only his boxers, and sat down on Sam's bed, trying to cover up the stains on
the sheets.
Sam got out of the shower and sniffed the air, wrinkling his nose.
"What's this smell?" he asked, glaring at Dean, who chuckled nervously.
"Oh, er. I got into one of my masturbation marathons" he answered, trying to
sound casual but really being as nervous as he could possibly be.
"One of my best, in fact" he added, before he could stop to think "I came
almost everywhere."
Sam gaped at him, looking at his own bed, and then he blushed furiously.
"I really hope there are clean sheets somewhere in this dump" he complained,
shifting his weight from one foot to the other "I don't want to go to sleep
surrounded by your come."
He grimaced and turned away, but not before Dean could see the outline of Sam's
cock through his sweatpants.
Sam was getting turned on, and Dean wasn't far behind.
He didn't call Sam on it, though, and kept on talking.
"Have you ever tasted your own spunk?" Dean inquired, crossing his ankles and
grinning at him.
Sam's expression got even more disgusted, and he didn't answer.
"I have, you know" Dean confessed "and not only my own."
Sam stared at him, his expression shifting from disgust to something else that
Dean didn't dare identify, before he turned completely away, and that gave Dean
a perfect view of his round ass, which only made Dean harder.
Dean's cock was throbbing, and the head was already pressing against his
waistband, so he decided to kick it up a notch.
"Maybe the smell is not mine, though. Maybe it's yours. Maybe you jerk off in
your bed every night, maybe even in the morning while you shower."
Dean stood up and slowly walked up to Sam.
"Maybe you did try your jizz and you even liked it" he whispered.
Sam shoved him back, his face livid, and threatened Dean.
"I'm gonna kick your ass if you don't shut the fuck up" he hissed, and Dean
almost came right then and there.
Kick his ass?
Did Sam really want to fight with him when they were both hard and turned on?
"Whatever you say, Samantha" Dean mocked him, and the insult sorted the desired
effect.
Sam turned abruptly, jumped on Dean and threw him on the floor, face down.
Dean was older, and bulkier, but Sam was taller and had longer limbs.
Besides, Dean didn't really wanted to fight him, and he was definitely more
intrigued than scared.
He couldn't let Sam get away with knocking him down, though, so he started
hitting him back, trying to break free, until Sam forced him to turn.
As he did, Dean's boxers got caught on the dresser and yanked down and Dean's
cock jumped out, thick and hard and already leaking.
"Fu-fuck" Sam muttered, loosening his grip, staring at it, and Dean took
advantage of his uncertainty to invert their positions.
He threw Sam on the floor, and then got on him, blocking Sam's arms with his
legs.
That in turn brought Dean's cock a few inches from Sam's mouth, and his little
brother's eyes got crossed as he tried to focus on it.
"You're such a perv" Dean panted, chuckling "I should pee on your face in
retaliation."
Sam blinked and started flailing, shouting that he was going to kill Dean for
even thinking something like that.
Dean laughed some more, as Sam swallowed nervously, and both of them stared at
the precome dribbling on Sam's chin.
That was the last straw.
Sam arched his back and pushed Dean away, getting back in control and sitting
on Dean's chest, his ass right against Dean's face.
He grabbed Dean's heavy balls and squeezed them.
"Maybe I should shit on your face in retaliation, uh? What about that?" Sam
said, but Dean was sure that he was bluffing.
Or at least he had been sure until Sam's shorts were pulled away.
Dean had Sam's hole right in front of his mouth, and despite Sam's painful hold
on his balls he was still hard and turned on, so he got his tongue out and
licked the strip of skin between Sam's ass and his balls without thinking.
Sam must have had a raging hard on, at least considering the way his skin was
tense; his back went stiff as he let Dean's balls go and snapped his head back
to look at him.
"What-what are you doing? Dean..." his voice sounded like a plea, and Dean
forced his tongue away from Sam's body.
"Just cleaning you up, bro" he answered, jokingly "when you showered you missed
a spot."
And before Sam could protest any more, Dean pushed his tongue into Sam's hole.
Sam squeaked, clenching his ass around Dean's tongue and Dean had to use all of
his willpower to stop his cock from shooting.
The simple idea of being engulfed by that hot tight warmth made him dizzy, so
Dean closed his eyes and tried to concentrate on the lapping movements of his
tongue.
From time to time he stopped licking in order to suck little bruises into Sam's
skin or nibble at his ass cheeks, and suddenly he realized that Sam's hands
weren't on his legs no more.
Then Sam's ass started bouncing slightly against Dean's mouth, and he could
feel the tip of Sam's fingers brushing his chin repeatedly.
His little brother was jerking off as Dean was rimming his ass.
Dean took advantage of his now free hands to separate Sam's cheeks in order to
allow his tongue to penetrate deeper, and started fucking Sam's ass following
the rhythm Sam himself was setting with his fist.
As he heard Sam's breaths becoming erratic, he got his tongue out of Sam's ass
and squeezed it slightly.
"Don't waste it, Sammy" he said, his voice coming out a little hoarse "give it
to me."
Sam stilled, then slowly turned, taking his shorts completely off and staring
at his brother's face with an expression both eager and terrified.
For the first time Dean got to see Sam's dick, and his mouth watered at the
sight.
He slowly licked his lips, and Sam's blown pupils followed the movement.
"Do you mean it?" he asked, biting his lower lip.
"Because if you're making fun of me, Dean, I swear to God -"
Dean snorted and grabbed Sam's hips, moving them forward so that he could lap
at the head of Sam's cock.
"Want it" he muttered "want you. And you want me to, right?"
Sam nodded slowly, and moved closer, until his balls were right over Dean's
mouth.
Dean opened his lips and sucked them in, one after the other, licking and
nipping, impossibly turned on by Sam's little moans.
Sam's eyes, as he pulled his balls from Dean's mouth before and slowly fed him
his cock were filled with such deep love and adoration that Dean had to look
away.
He licked the whole length, stopping to pay special attention to the thick vein
under the head and then to the slit at the tip.
Sam threw his head back and started panting, alternating God, oh God with yeah,
fuck, come on, bro and Dean was completely lost in the sensations of Sam's hot
body everywhere around him.
The smell, which was sweat, motel soap and so distinctively Sammy got him
hooked from the first second, and Dean instantly knew that he was never going
to be able to live without it now that he’d had a taste.
Sam lost it completely as well, and started fucking Dean's mouth; Dean gagged
on Sam's cock - he never sucked anyone off before - but didn't stop and didn't
say anything, too scared that if he did Sam would get back to his senses and
put a stop to everything.
He tried to relax his throat and finally seemed to get the hang of it.
Meanwhile, his left hand had found his way back to Sam's ass, and his fingers
started to play with the puckered hole, already wet and loose after Dean had
worked on it with his tongue.
One of Dean's fingers found its way inside of Sam's body, and Sam got
completely out of control as Dean pushed his finger deeper, adding a second one
after a few moments.
With his other hand, Dean finally started jerking himself off, and it didn't
take long before he was coming, harder than he ever did, and he could feel his
come dripping down Sam's back.
He recollected it and used it to push three fingers inside of Sam's ass; as he
scissored them, Dean hit something, and from the way Sam shouted and came
instantly down his throat, Dean could hazzard a pretty good guess about what it
was.
Once they were both spent and satisfied, Sam rolled onto his side, his limp
cock on Dean's leg.
Dean smiled lazily, then he shifted until he could lick the last drops of come
away from Sam's cock, which valiantly twitched, and Dean chuckled.
"So" Sam started, sighing dreamily.
"So" Dean echoed "when will it be the next time I'll have to kick your ass,
bro?" he asked, winking at him.
Sam arched an eyebrow.
"You kicking my ass? That's not the way I remember it" he retaliated.
Dean grinned.
"Guess we'll have to fight again soon."
