Notes
     Sequel to Curiosity Doesn't Necessarily Kill, but I guess you don't
     have to read that one in order to understand this one.

The sun began its ascent into the sky at around 5:30 AM the next morning.
Through the shear curtains of Sam and Dean’s motel of the week, the it
illuminated the scene of last night’s excursion: Dean’s clothes in a crumpled
pile in front of the bed playing host to the two brothers, and Sam’s shirt and
jeans discarded on the floor next to his side of the bed. Sometime during the
middle of the night, Dean had woken up briefly and removed his little brother’s
clothes, thinking he’d be more comfortable without the buttons on his jeans
digging into his skin, as he lay tangled in his older brother’s limbs.
Dean’s eyes slowly adjusted to this scene as he was called from sleep by the
sun’s intrusion though the curtains. For the first time in what seemed like
forever, Dean felt completely content, breathing deeply and catching little
whiffs of his Sammy before he exhaled. Sam’s head was tucked under Dean’s chin,
both hands loosely balled against Dean’s chest, legs interwoven between his
older brother’s. Upon studying his face for a minute, Dean came to the
conclusion that it wasn’t just him who was completely content.
“Sammy,” Dean whispered, awaiting a response. “Hey, kiddo,” Dean whispered
again, nudging him a little. “You plan on sleeping all day?” The response he
got was a low grumble, to which he laughed. “Rise and shine, Sammy!”
Sam’s eyes blinked open, his older brother coming into focus. “What time is
it?”
“Time for breakfast, that’s what.” Dean shuffled out of bed and put on the
boxers he found on the floor. “Bacon and eggs okay? That’s all we got.” Nodding
in agreement, Sam padded off to the bathroom.
Sleep still clouding his thoughts, the sight of Dean standing in front of the
stove, naked except for the boxers, was all too much for Sam. When he emerged
from the bathroom, Sam had to remind himself to breathe upon seeing his brother
like that. Running a hand through his hair, he search for clean clothes in his
beat-up duffle bag and sat on the foot of the bed, facing Dean. As Sam slipped
on his socks, Dean called out from over his shoulder.
“You know, Sam,” Dean started, turning off the stove and setting two plates of
food on the small circular table. “If you wanted to see me naked, all you had
to do was ask.” Sam could practically hear the cocky smirk in Dean’s voice as
he continued. “You didn’t have to come up with some story.”
“That wasn’t what I was tryin–“
“C’mon, Sammy, I’m your older brother, which means I’m always right.”
“Dean, how did you kn–“
“You kiddin' me? What don't I know about you, kid?” Dean fully turned to face
Sam, smiling. Sam looked embarrassed, not meeting Dean’s gaze. “You can’t lie
to me Sammy,” Dean said, walking slowly over to the bed his little brother was
sitting on. Crouching down to his level, Dean put a hand on Sam’s thigh. “I’ve
known all along, little brother.” And with that, Dean rose and ran his fingers
of the sides of Sam’s torso. Sam gasped, finally meeting Dean’s gaze. His usual
deep green eyes were being swallowed by the blacks of his pupils, arousal and
lust very prevalent. After discarding Sam’s shirt, Dean pressed on Sam’s chest
and pushed him back against the covers on the bed. Sam shuffled further up the
bed, resting his head on the pillows but never taking his eyes off of Dean.
Following Sam, Dean crawled up the bed, stopping when his face hovered over
Sam’s crotch, which was beginning to swell. With light and cautious fingers,
Dean unbuttoned Sam’s jeans, brushing his hipbones as he pulled them down the
length of Sam’s legs. Looking up at Sam, Dean asked, “is this okay?”
Sam nodded furiously, not being able to find his voice. He swallowed hard and
continued watching his brother. Hooking his index finger under the elastic of
Sam’s boxers, Dean let go, letting the elastic snap on the skin below his
brother’s belly. Sam squirmed, silently begging his brother to continue. Dean
directed Sam to arch his back, and he began peeling Sam’s boxers off with his
teeth. When Dean’s nose skimmed Sam’s cock, Sam signed, a bead of pre-cum
dripping onto his skin. Dean tossed Sam’s boxers into the pile of the rest of
Sam’s clothes on the floor, and turned his attention back to his brother’s hard
dick. Wrapping his right hand around Sam’s member, he began to stroke it up and
down, licking the shaft from root to tip, eliciting a squeal from his younger
brother.
“Dean,” Sam gasped, closing his eyes and gripping the sheets. “Dean, please.”
Smiling to himself, Dean took Sam’s entire cock into his mouth, making Sam moan
long and loud. Dean bobbed up and down on this brother’s dick, right hand
following the same motions, wrapped around the flesh that his mouth wasn’t
currently occupying. In that moment, Dean tuned out everything else; his focus
was solely on taking care of his brother, and exploring this side of him that
Dean had never had the opportunity to experience before. He worked Sam’s dick
like a pro, using his mouth to encase it completely. Slurping and sucking his
little brother’s member, he glanced up at Sam to see his expression, which
resembled that of complete and utter bliss. Sam’s eyes were pressed tightly
shut, and his upper row of teeth clamped down on his bottom lip as he whimpered
and spasmed. His flat stomach clenched and he pressed his body further into the
bed, barely keeping it together. If his mouth wasn’t so full of cock, Dean
would’ve smiled and laughed. A familiar sense of pride stirred within Dean
knowing he could make his brother feel like this.
What Dean was doing to Sam felt so right, like they should’ve been doing this
all along; like everything had finally fallen into place. Stroking his own hard
dick through his boxers was kind of a reflex upon seeing Sam like this. Dean
played with his tip through the thin fabric, wondering what it would feel like
to have Sam’s red, plump lips surrounding it. If he wasn’t so prideful, Dean
would’ve come just on that thought alone, accompanied by the feeling of the
head of Sam’s dick hitting the back of his throat, but he wanted to last. He
wanted Sammy to come first.
The closer he got to orgasm, the more vocal Sam became. Phrases like “holy
shit,” “oh my god, yes,” “Dean, ahhh fuck,” and “please, Dean, please,” were
the only words to leave his lips at the time. Every time Sam said something, it
acted like an encouragement for Dean. Dean started humming, probably some
Metallic tune, and Sam sucked in a sharp breath.
“Oh my god, Dee, whatever you’re doing, don’t stop,” Sam breathed out in
ecstasy. Halfway through the second verse of Some Kind of Monster, and without
warning, he shot his hot load down his older brother’s throat. Dean’s eyes
widened at first, and he momentarily panicked, but as he slowly got used to it,
he suckled Sam and tried to milk every ounce of hot come out of him. Looking
up, he found his little brother watching him with an expression that was equal
parts lust and equal parts surprise.
“Shit, Dean, I’m so sorry. I didn’t know,” Sam began mumbling an apology as he
watched his brother’s throat bob, swallowing every last drop. Dean winked and
grinned, crashing his lips to his brother’s. In their first kiss, their tongues
clashed. Sam let Dean take control, submitting himself completely. Dean laughed
into the kiss, placing one hand on the back of Sam’s neck to pull him closer.
Their bodies meshed into each other, and they moved in a synchronized rhythm
that felt completely natural. Dean pulled back, smirking.
“You like tasting yourself on my lips, huh, baby boy?”
Sam’s response was practically a moan. That nickname, like so many others Dean
has for him, drove him insane. “Dean, that was…amazing. I’m sorry, I should’ve
lasted longer,” Sam looked away, bashful. Dean tilted his chin up, forcing Sam
to meet his eyes.
“Yeah, you should’ve, geek boy.” Dean laughed as Sam shoved him. The next part
of his response was low, almost a growl, sending shivers through Sam. “But hey,
as long as you’re ready for round two, I don’t care.”
