     Square Filled: Road Head
"Happy birthday, Sammy."
Sam blinked a few times, rolling over and looking blearily at Dean. "Huh?"
"It's your birthday, man. You're sixteen. I expected you to be jumpin' around
an hour ago."
"What time is it?" Sam groaned, burrowing a little deeper under the ratty motel
cover.
"About nine. Come on. I made you breakfast."
"Where's Dad?"
"Took off already, working on interviewing folks," Dean said. Sam peeked at him
over the covers.
"For how long?"
"Don't know. He said he'd give you a break since it was your birthday. So we
have the whole day to hang out. Why don't we go for a drive?"
Sam seemed to consider for a second before kicking the covers down. Dean's grin
grew. He cupped Sam's cock through his boxers.
"This for me?"
"Shut up," Sam mumbled, pushing Dean's hand off his cock and rising.
"Aw, no morning quickie on your birthday?" Dean teased as Sam padded to the
bathroom.
"I will piss on your head, I swear," Sam called back.
Dean followed him to the bathroom, leaning on the doorframe while Sam pissed.
"So what's the birthday boy want, huh?"
"His big brother to not be a jackass for five minutes?"
"What about his boyfriend?" Dean waited until Sam was washing his hands to come
up behind him. He curled his arms around Sam's middle and kissed up his neck.
Sam smiled a little, leaning his head on Dean's for a moment. "I think that's
the first time you've actually called me your boyfriend, you know?"
"Is it? I mean-- Haven't gotten a piece of ass other than yours in months. That
makes us steady whatevers, right?"
Sam smirked. "Guess it does."
He dried his hands and turned around in Dean's grip, hooking his arms around
his neck.
"I'm almost as tall as you."
"Yeah, yeah, don't rub it in. You'll stop growing here soon, I stopped just
after I turned sixteen."
"Bet I don't. Bet I get way taller than you."
"In your dreams, stretch."
They both laughed, letting it faded to a comfortable silence. Dean leaned
forward first, brushing his lips against Sam's mouth. It was Sam that deepened
their kiss, not caring about morning breath as their lips slid together, a
comfortable dance they'd been doing for months now.
Sam didn't expect Dean to say yes. He'd been fighting the way he felt about his
brother for so long, when it finally came out just four months ago, he expected
Dean to hate him. To turn and walk out and never come back - or to tell their
father. He hadn't expected Dean to grab him by the hips and slam him against
the wall. He hadn't expected Dean to kiss him until he couldn't breathe, their
cocks aching in their jeans. He hadn't expected Dean to take his virginity a
month later, stretched out on a blanket in the middle of a field next to the
Impala. He hadn't expected any of this -- but he was damn happy it had
happened.
Dean broke the kiss, reaching up to tug on Sam's shaggy hair.
"Seriously, Sammy. What do you want?" He asked again.
"I don't know, Dean. I know we're short on money... Why don't we just hang out,
watch a movie or something?"
"We do that all the time," Dean argued. "I wanna do something special for you."
Sam chewed his lip, trying to think of something fun they could do that
wouldn't cost too much money.
"Hey... Why don't we take the Impala out to a make out spot? It's early, so
there shouldn't be too many people. We can make out in public and if someone
spots us, they'll have no idea they're watching two brothers." Sam's voice
dropped to a low murmur by the end of his suggestion. He slid his hands down to
Dean's hips and back to his ass, giving a squeeze. Dean smirked.
"Sam, you got a dirty mind... I like it. We can pick up some sandwiches or
burgers to eat too. Make a whole day of it."
Sam grinned and nodded. "Just lemme take a quick shower before we go, okay?"
"Why? You're just gonna start sweating again."
"Because I'm not a brute." Sam poked Dean in the ribs playfully. "I promise
I'll be quick."
"Yeah, alright. I'll go pick up something for lunch. Any requests?"
"Just something cheap," Sam said, tugging his boxers off and turning on the
water. He smiled back at Dean before stepping in and shutting the curtain.
***
Sam was brushing his hair, a towel wrapped around his waist when Dean pushed
open the bathroom door.
"Perfect timing," he said.
"I got us some sandwiches and drinks and some treats too. Waiting in the cooler
for us. Ready to go once you get dressed."
Sam nodded, setting his brush down and sliding past Dean into the main room. He
gave an indignant squawk when Dean grabbed his towel, rendering him nude.
"Dean!"
"I forgot something," Dean said. He tossed the towel into the bathroom. Before
Sam could ask what he forgot, Dean pounced, pinning him to the bed and kissing
him hard.
Sam laughed, struggling to get out from under Dean's grip. "Let off!" He
shouted, though there was no venom behind his words.
Dean listened anyway, climbing off him. When Sam rose to get his clothes again,
Dean grabbed his wrist. "I said I forgot something."
"What'd you forget?" Sam asked. Dean's grin grew predatory.
"Someone needs birthday spankings."
Sam's eyes bulged. "You're not serious."
"Oh I'm serious. Sixteen is a very important birthday, Sam." He sat down on the
other bed and patted his knees. "Come on. Gotta get these over with before we
go on our little outing, don't we?" He asked.
Sam groaned. He complied, folding his long body over Dean's thighs, his bare
ass exposed to the air.
Dean palmed his ass, groaning. "God, you grew up so nice, Sammy," he murmured.
Sam sighed softly, letting his eyes slip shut as Dean kneaded one cheek then
the other. "Dean--"
"Shh... I got you, Sam," Dean assured him.
He drew his hand back and swatted Sam's ass lightly, just enough to feel. Sam
jumped a little, glancing back at Dean. "Now you're just teasing."
"I'm just getting you warmed up. Behave or it'll be double."
"You can't double up on birthday spankings, you jerk."
"Nope. But I can give you sixteen birthday spankings and then sixteen more for
being a little bitch." Dean brought his hand down again, hard enough to really
sting this time. Sam squeaked, his hips jerking forward.
Dean picked up a steady pace after that. Sets of three, one on each cheek and
one in the middle, before he'd pause and rub Sam's reddening ass. Somewhere
along the way, Sam's cock decided to get involved, hard and aching against the
denim of Dean's jeans. Sam groaned softly on each swat, rutting his hips
against Dean's thigh to try and get any sort of stimulation he could manage.
"Dean, please!" Sam begged when Dean's hand came down for the sixteenth time.
"Whatcha need, Sammy?" Dean asked, rubbing his red, welted ass.
"I gotta come," Sam panted. Dean let him up and Sam stood on shaking legs, his
cock bobbing between his thighs.
"Well, look at that. My little brother likes to be spanked. Want me to take
care of that, baby boy?" He reached out, curling his fingers around it and
twisting his wrist. Sam hissed, nodding quickly.
"Please."
Dean leaned forward without argument. He let Sam's cock slip between his lips,
swirling his tongue around the leaking tip before beginning to bob his head,
letting it hit the back of his throat before pulling off and repeating.
Sam let his fingers slide through Dean's short hair, tugging ever so gently to
urge him on. His head fell back, low groans slipping from his parted lips. It
felt so dirty - doing this in the middle of the day, in the middle of their
motel room. Their dad could walk in at any second and there would be no
explaining this away.
But that was half the fun of it for the brothers. They knew their relationship
was about as dirtybadwrong as it could get, and they loved that. They loved the
risk of even kissing in public, let alone having sex where they could get
caught. Sam being underage was bad enough, but if someone were to look close
and find out they were brothers on top of it -- they'd have a lot more to worry
about than a pissed off dad.
Sam's fingers twisted the shoulders of Dean's flannel, tugging upward.
"Dean, gonna come," he panted. Dean ignored his warning, continuing to bob his
head along Sam's stiff, aching shaft. Sam grunted Dean's name over and over, a
mantra of worship, as he came down his throat, his thighs shaking with the
force of it.
Dean pulled back when he'd sucked every drop from Sam's softening cock, licking
his lips. He grinned up at Sam.
"Thanks for breakfast," he teased, rising. Sam swung, punching him lightly in
the shoulder.
"Dick."
"Yeah. That was breakfast. Get dressed, come on." He pressed a kiss to Sam's
forehead before heading out the door and leaving Sam to dress in the motel room
alone.
***
Sam's legs were stretched out as far as they could go in the passenger seat as
they sped down the highway toward the quiet little spot in the woods that
teenagers in the town often used as a make out spot. His shirt had been shed,
tossed into the backseat as the car heated up despite the windows being rolled
down.
Classic rock blasted on the radio - one of their dad's tapes that somehow found
their way into Dean's possession when he'd inherited the Impala on his
sixteenth birthday. Part of Sam wondered if their dad would give him anything
special for his sixteenth. Certainly nothing as special as the Impala - those
sorts of gifts were saved for the perfect son. The eldest, the perfect soldier.

Sam wanted to envy Dean. Hell, he wanted to hate him sometimes, but he
couldn't. Despite how perfect their dad thought Dean was, Dean was HIS. Sam
would always know Dean better than anyone on the face of the planet, and he was
perfectly okay with that.
He didn't need a special gift for his sixteenth birthday. Because being next to
Dean, driving down the highway without a care in the world - that was special
enough for Sam. That was the perfect gift.
Sam looked over at Dean, unable to help but smile at the wide grin on his
brother's freckled face. He reached out, letting his hand slide up Dean's leg.
The rough denim scraped his callused fingers on their way up. Dean's thighs
parted seemingly of their own volition, and Sam caught his hands tightening
just a little on the wheel.
"Dean," Sam asked, letting his fingers barely graze the fly of Dean's jeans.
"What?" Dean's voice was laced with tension.
"Have you ever gotten road head?"
Dean's fingers tightened further, knuckles going white. His thighs spread open
a little more, a product of his subconscious, clearly, and Dean's Adam's apple
bobbed.
"No, Sammy. I haven't."
"Do you want it?"
"That's dangerous," Dean whispered without much worry in his voice. He was just
playing a part.
"You've driven at a hundred miles an hour. You've shot guns and set off
explosives... You're telling me you can't keep your cool driving the speed
limit while I'm sucking your cock?" Sam slid steadily closer to Dean as he
spoke, so the final word was right in Dean's ear, hot breath skittering down
his already sweat dampened neck.
"Fuck, fine, Sammy just-- Lemme slow down a little, okay?" Dean pleaded.
"Anything you want," Sam whispered.
He busied himself freeing Dean's cock from his jeans, moving slow so Dean could
safely slow the car down to just under the speed limit. It wasn't enough to get
noticed by a highway patrol officer, but it was enough for Dean to maintain
some semblance of control.
Sam glanced at the speedometer before sinking down onto the seat. He folded
himself up so he wouldn't be visible unless someone looked directly in the car,
his nose bumping against Dean's hard cock, jutting out through the fly of his
jeans.
When Sam was comfortable, he wrapped his lips around the tip, giving a gentle
suck.
"Fuck--" Dean panted. Sam felt his hips jerk a little.
"You okay?" He worried.
"I'm good, just takes some getting used to. You're okay, Sammy. I'll keep us
safe."
Sam swallowed Dean's cock down again, inch by inch. He could feel the silky tip
nudge the back of his throat and suppressed a gag, instead letting it slide out
before trying again. 
Dean was breathing hard above him, and Sam could feel the tension in his
thighs. He sank back down, relieved when he was able to push Dean's tip into
his throat. He gagged a little, but that was okay. Dean confessed one night
that he loved hearing Sam gag. 
He began to bob his head quickly, opening his mouth to let out excess drool, as
well as to make sure Dean could hear the wet click and gulp of Sam's throat as
he struggled.
One hand fell heavy in his hair, twisting it gently.
"Fuck, Sam, I'm not gonna last long," Dean admitted. Sam sped up at that
admission, letting himself cough and gag around Dean's cock. He knew it made
his throat tight, fluttering in just the right way. Girls couldn't do this for
Dean, only Sam. 
Dean's fist tightened in Sam's hair.
"Don't you fucking spit," he threatened. Sam rolled his eyes even as he gagged,
his nose pressed tight to the rough denim of Dean's jeans. 
Dean's cock throbbed, seeming to swell before he began to come. Hot, thick
ropes coated Sam's throat as he struggled to swallow, not losing a drop. 
When Dean's arm relaxed, Sam yanked his head back, gasping in air as quick as
he could. 
"Shit, did I hold you down too long?" Dean worried. Sam shook his head.
"No, it was perfect," he rasped. 
Dean smirked a little. "Dad's gonna think you're sick. And look, didn't wreck
us."
Sam laughed, helping to tuck Dean's softening cock back in his jeans. He
snuggled close to him, smiling wider when Dean slung his arm over his
shoulders.
"I thought it was your birthday. Why'd I get road head for a present?" Dean
asked. Sam shrugged.
"Because." 
When Dean continued to glance over, clearly waiting for Sam to continue, Sam
rolled his eyes.
"Because I like sex with you. And I like being with you, okay? Whether we're
just hanging out or you're choking me with your dick-- I just like it."
Dean grinned, showing almost all his teeth. "Aw Sam, you little sap." Sam
punched him in the side.
"Shut up, jerk."
Dean laughed a little, pressing a kiss to Sam's temple. "I like being with you
too, bitch."
