****** A Choice Must Be Made ******
by The_Heart_of_an_Angel
Summary
     Looking at your big brother's muscular arms and protruding hips,
     wanting his big hands on you... It's wrong right? Sam isn't so sure.
     All he's sure about is that Dean is all he's ever looked up to, and
     yet all he's ever wanted. So, he has to make a choice...
     Let out his feelings, or keep it to himself?
***** Chapter 1 *****
Sam was almost positive that the first time he'd looked at his brother and
thought "damn, I want those hands all over me..." happened when he was 12.
That's about the normal time that any growing boy starts to learn about sex.
However, it isn't the normal time that any boy learns that he wants to have sex
with his older brother.
He remembered that first thought very clearly. John had been outside with Dean,
teaching the 16 year old how to fix something on the Impala. As if Dean hadn't
been watching their dad fix the car for years. Sam was sitting on the porch,
admiring the cool spring day in Western New York. It was surprising that it
wasn't muggy or even very cloudy, as was usual for spring in that region. It
was windy, the sweet smell of grass and flowers moving swiftly through the air.
Normally, the Winchesters didn't stay in a regular house, rather than a stinky
motel. But, this time they'd managed to get a vacant old colonial through one
of John's hunting buddies. It had a nice porch, so Sam decided to get some
fresh air and watch his brother and father do some car work.
By the time Dean and John were finished, Sam was bored. He remembered that at
this point he was picking the peeling paint off of the wood of the porch posts.
He heard John slam the hood closed and looked up, happy that he'd get to
finally do something with them. Sam wasn't interested in cars, so John never
forced him to learn. It wasn't essential for their training anyway.
Sam watched the two of them walk back to the house from the dirt driveway. His
eyes widened as he saw Dean. He wasn't sure what it was- maybe the sunlight or
the dizzying scent of pollen- that made him feel so warm as he watched his
brother. The guy was sweaty and covered in oil and dirt. He wiped the sweat
that dripped from his forehead away and slung a dirty rag over his shoulder.
Sam's cheeks had reddened, eyes catching the sight of the pectoral muscles that
had Dean's tank top cleaning to them with sweat. His arms, muscles bulging as
he lifted them to stretch, his stomach poking out of his tank. A warm feeling
spread across Sam's crotch as well. Just the sight of his brother like this had
his 12 year old mind super glued to the thought of Dean being sexy. Sexy. He'd
never described anything as that word before. It was only two years later, when
he was 14, that Sam realized why he'd labelled Dean as such a thing.
14 year old Sam recalled this certain scene is his dreams many times. Often
waking up to that same tingling warmth all over his body, especially around his
crotch. Now that he was 14 years old, he also knew how to do certain other
things. Things he's heard about from the kids at his numerous schools. He
learned about guys and girls getting together and making out. He heard things
about makeout  parties, and guys getting skinmags from their dad's secret
stash. 
 
Sam had never been interested in any of this though. That was one fact that
solidified his assumption that he was different than other guys. He had no
desire to kiss girls or touch their breasts. He wanted to kiss Dean, and touch
Dean's chest and for Dean to touch him.
***** Chapter 2 *****
Sam always remembered that image of Dean, shirtless. It was hard to forget when
you live together and use the same bathroom. Their rooms were right across the
hall from each other and sometimes Sam got to see Dean walking shirtless to the
bathroom for his shower. And Damn it if Sam didn't get a little hard every time
it happened.
Sam thought about this occurrence as he sat in their musty living room, barely
watching cartoons. He was too distracted. Today, in particular, he couldn't
stop thinking about it. He wasn't sure why.
He heard the creaky front door slam shut as Dean entered the house.
"Hey, Sam." Dean came up behind the couch and rested his elbows on the back
next to Sam's head. "Mind if I watch with you?"
Sam shook his head, keeping his eyes on the TV. He was almost positive that if
Dean came any closer, he was going to get hard. The buzzing of arousal was
already hanging out in his lower abdomen. He was way oversensitive today.
Dean climbed over the back of the couch and plopped down next to his little
brother, so close their shoulders and knees brushed. That's how Dean always
seemed to like it: close proximities and gentle touches. Sam liked it too, but
probably for a less innocent reason.
Sam's face filled with warmth, flowing up his cheeks and down his next. Why,
you ask? Dean's arm was around him, and Dean's head rested on his shoulder.
Damn it, if only Dean weren't Sam's brother. He'd be looking at him. He'd be
leaning in and kissing the god damn breath out of him. Sam was 14 and hadn't
ever had sex, but he knew some interesting things about it. He knew he wanted
it with Dean.
He had a whole scenario set up in his head. Dean pushing him down into the
couch, holding him forcefully into the cushions while he rubbed their hard-ons
together. Dean breathing and moaning into Sam's ear, asking him if he was hard
just for Dean. Of course he would be. Sam was always hard for Dean, but Sam
loved the idea of Dean dirty talking into his ear.
Of course, none of that would ever happen. Dean was probably straight. And they
were brothers, of course.
Sam was starting to get hard, so he forced a smile at Dean, and told him he had
to pee. He then bolted to the bathroom as soon as he was out of Dean's sight
and locked himself in there to jerk off to images of Dean fucking hard into
him.
***** Chapter 3 *****
Sam and Dean were at a new school for the millionth time. They somehow ended up
with the same lunch (Sam thinks Dean pulled a few strings with the guidance
counselor) and were sitting in the loud, smelly area in the corner. Neither of
them had made any friends yet, but it's only been a few days. Sam always
managed to make at least one friend. Dean... It depended. He could be invited
to tons of parties in one town, and a total loner in another. 
They sat together, by themselves, and it was fucking killing Sam. Watching Dean
at home was easy; he could leave at any moment if a jerk off-worthy moment
happened to arise. But... At school... Sam was screwed. And watching Dean eat
was usually one of the worst jerk-worthy moments. 
Sam couldn't help but imagine that the fucking hot dog Dean was shoving in his
mouth was actually his cock. And damn did it make him hard. It didn't help that
his brain uncontrollably partnered dirty talk along with it. 
 
Dean bit into the footlong hot dog and Sam's brain moaned "Fuck, yeah, Dean.
Suck my cock." His mouth went dry as he stared, and his sandwich was held
limply in his hands, uneaten.
Dean raised an eyebrow at Sam. The suspicion held on his face made Sam's heart
beat hard in his chest and he finally raised his sandwich to his mouth and took
a bite. He looked away awkwardly, staring at anything else in the room.
Dean chewed quickly so he could swallow the huge bite. "Something on your mind,
Sammy?" He asked, scrutinizing Sam's face. The younger brother shook his head,
chewing turkey and mayonnaise.
Dean looked unconvinced, but continued eating anyway. Sam made quick glances,
and when he was done with his sandwich, he held his hands in his lap. He
allowed himself a little friction through his jeans, just enough to send
shivers up his spine. His mouth hung open as he subtly rubbed his hard-on. 
Dean looked at him and squinted. "Sam, you look like you're going to be sick.
You sure you're okay?" 
Sam let out a little breath and moved his chair so he was farther under the
table. "Yeah, I'm fine." He bit his lip and held back a moan. Damn it, he
needed release so badly. He wanted Dean to touch him. Make him feel filthy and
bad for getting hard for him at school. Fuck, he wanted Dean to grab his junk
through his pants and tease. 
"Well, if you're sure." Dean shrugged, but kept an eye on him. He took a swig
of chocolate milk. 
"I think I just have to pee." Sam grabbed his backpack and used a binder to
cover his erection as he hurried out of the cafeteria and to the nearest
restroom. 
Once in the safety of a stall, he thought "Fuck it." He was going to masturbate
at school and no one was going to stop him. Once making sure that anyone that
was in the bathroom had left, he locked himself in the stall.
He rubbed himself through his jeans and canted his hips forward. He let out a
little whine, and bit his lip. After that, he let his imagination take
control. 
Dean and Sam were at home, sitting on the couch. Dean kept giving him heated
glances and biting his lip, making the bottom lip red and plush. "Sam?" Dean
leaned over him and whispered in his ear. "I can see the way you want me to
touch you." His hand rubbed at the hard length threatening to break free of
Sam's jeans. Dean licked the shell of his ear and bit the lobe. "I'll touch
you. Just the way you like. I'll fuck you hard, huh, baby brother? Want that?"
Sam let out a loud moan, he'd freed his cock from his jeans and was slowly
rubbing the head, smearing pre-cum to make it more slick. He leaned against the
stall down with his left hand. 
"Fuck yeah, Sammy. Let's get that hot cock out." Dean was already sliding his
hand up and down his length. "So hot, Sammy. I wanna be inside you so bad." He
rubbed his thumb over his slit. 
"Fuck, Dean!" Sam allowed himself to whisper aloud. He followed the hand
motions of Dream Dean and rubbed his thumb in circles over his head. The
pressure sent shocks of pleasure through his groin. "Fuck... fuck. Fuck!" 
Dean skipped right to being hot and hard and thrusting into Sam's ass. Pushing
him against the couch, forcing him into the cushions and fucking him hard. His
hot breath all over Sam's neck. "Fuck, so good, little brother. So hot for me.
So tight. Feel that?" His pace quickened, his teeth coming down to bite Sam's
neck. They moved together, Sam pushing back into his thrusts. "You're so hot,
Sam! Nng! Ah!" Dean came in Sam's ass. Sam imagined it to be wet and warm. 
Sam tugged on his cock. He was so close to cumming. He was panting and letting
out high, breathy whines.
"Sam?" The rough voice echoing in the bathroom sent Sam over the edge. He came,
painting the stall door. 
"Dean?" He let out shakily, quietly. He took some toilet paper and wiped up the
door, then tossed it in the toilet. 
"Sam, let me in." 
Sam tucked his cock back in his pants and opened the stall door. He had no idea
if Dean knew what he'd been doing. Most likely he knew exactly and Sam was
fucking terrified. His heart was pounding loudly and his head was spinning.
Fuck. Dean was going to be mad. 
As he opened the stall door, Dean didn't appear to be angry. But, his eyes were
dark, and he grabbed Sam immediately and pushed him roughly against the stall
wall. One hand on his shoulder and the other gripping his hip.
His breath was warm on Sam's ear.
"You fucking jerking off to me, little brother?"
