****** Don't You Have A Test Tomorrow? ******

Summary
     Sixteen-year-old Sam is spending the night studying for an exam and
     Dean is having none of it.
“C’mon, Sammy, first night off on the job and you’re freaking studying?” Dean
threw another paper ball at Sam.
Sam clenched his jaw, realizing he had reread the same sentence four times in a
row thanks to his dumbass brother flicking things off his head. He erased the
note he was writing in the margins of his textbook, “I’m sorry getting a G.E.D.
isn’t really my thing.”
He could hear Dean’s motel bed squeak from behind the couch. “Whatever,
dumbledork.”
“Did you think of that one all by yourself?”  Sam etched a bracket next to one
of the paragraphs he was reading. A hand reached down and stilled his pencil.
Dean’s lips were pulled next to Sam’s ear, “C’mon, I’m bored.” His hand trailed
up Sam’s arm and to the buttons of his shirt.
“You’re annoying,” Sam face reddened, but he didn’t move.
“Really? Because I think I’m about to rip that book out of your hands and fuck
you on the floor if you don’t stop reading in about five seconds.” Dean kissed
the nape of Sam’s neck, undoing three buttons rapidly.
There was a tongue making a long, slow swipe against Sam’s jaw as he continued
to look down at his book. Oh who was he kidding? Fuck it. “When’s dad coming
home again?”
He could feel Dean’s smirk against his cheek, “The morning after tomorrow.”
“Fine, get on the bed.”
A quick kiss was pressed on Sam’s check, “Yes, sir.” He removed his hand from
Sam’s shirt and practically ran back to the bed behind them. Sam sighed
heavily, shoving the textbook off his tight lap and following him- making sure
not to make eye contact with the Dean’s ass already up and wagging in the air.
Dean dragged his belt out of its loops and placed it next to him on the bed,
turning around and shooting Sam a gnarled grin.
Sam couldn’t stop the whimper that came out of him before blurting, “I hate
you.”
Dean pulled down his jeans’ zipper, “Oh yeah? Show me how much.” His next
thought was quickly interrupted by the hard yank down of his pants and slap
delivered to his ass. He cried out as his entire body jolted.
“I’m so shit of your shit!” Sam huffed while smacked harder, “Always bugging
the hell out of me, always acting like everything’s yours, stealing my stuff-”
Dean shouted as a blurry of slaps fell on his reddening skin.
Sam pulled back to remove his shirt and jeans, letting out a shaky breath at
the site of Dean’s sore, pink ass still in place for him to use. Dean panted
into the sheets, shoulders bobbing as he leaned on his elbows.
“Take off the rest of your clothes and turn around.” Sam commanded.
Dean pushed himself off from the bed. He knew he was giving Sam a show as he
arched his back and stretched, pulling his black t-shirt off slowly and flexing
the dimples of his back and shoulders. He turned around to face his brother
with his cock bobbing against his stomach and leaving a smudge of pre-come. He
smiled, “Enjoying the view, sir?”
Sam’s cock twitch was visible to the both of them.
Dean laughed, leaning backwards on the bed and spreading his legs farther
apart, “Be more obvious, please.”
“Shut up!” Sam growled as he tackled Dean and pushed him into the mattress.
Dean pulled Sam’s head down for a kiss. The action was reciprocated with a
soft, boyish gasp into his mouth. Large hands cupped Dean’s jaw. Sam’s legs
straddled Dean’s lap and their cocks nudged each other, jolting both of them
with a heat filling their abdomens.
“Shit,” Dean pulled back, eyes still closed as he snaked his hand between them
and held their cocks in a lose grip- grinding hungrily against Sam with a shaky
breath. His eyes opened but remained half-lidded, catching Sam’s face as the
boy bit his lip with pink cheeks and sweat building on his brow. Sam rocked his
hips, thrusting through Dean’s hand and smearing pre-come over both of their
shafts.
“God… Sam, you dirty boy,” Dean exhaled, smirking at Sam’s fogged over eyes and
mouth hanging open as the thrusts came harder. Dean tightened his grip, “What
happened to my punishment?”
“J-just keep going!” Sam exhaled.
Fuck. That’s it.Dean gave their cocks one last squeeze before using the same
hand to gently push Sam on his back. Dean stared down at his brother. Trailing
down from the boy’s face to his chest was a hot blush over his skin. His lips
were red and swollen from being kissed to hell- eyes blow out and staring back
at Dean like he was the only thing on Earth. Dean gave Sam a small grin,
sliding his hand from his warm neck to the trail of hair leading down to his
cock.  Sam’s eyes widened a little as Dean moved back and bent down over his
cock, green eyes staring up at him while breathing over the sensitive flesh.
“Please…” Sam said brokenly. He thrashed his head against the covers when the
head of his cock disappeared past full lips into surrounding, wet heat. “Fuck!”
Dean pulled off Sam’s cock and began stroking it quickly, “Again with the
filthy mouth.”
“Says the one with a dick in his,” Sam huffed.
“Touché.” Dean dived back down. His tongue swirled over Sam’s head on the way
down, lapping up the pre-come leaking at an even flow now. His strokes
continued as his head bobbed. Dean closed his eyes, hummed through Sam’s head
and shaft and feeding off of the constrained jerks Sam’s legs made underneath
his arms and the panting heard from above with the “Oh fucking hell, Dean,
yes!” bursting from Sam’s mouth. Dean could feel the muscles in the legs
beneath him begin to tighten before he pulled off again-slowing down his hand
and shooting another smile up at the boy now staring incredulously back down at
him.
“Not so fast,” Dean wiped the liquid off his lips with his free hand and used
it to coat his fingers. He pulled them together and then apart, watching the
lines of pre-come and saliva form between his digits. “You want me to fuck you
this time, am I right?”
Sam felt his cheeks burn hotter. Sam groaned, shutting his eyes away from the
wicked, knowing smirk in front of him.
“Awesome,” Dean slide the a coated finger down Sam’s shaft to his balls,
pressing lightly against the skin between them, before traveling to the
quivering hole presented up to him. Without warning, Dean simply raised an
eyebrow at Sam before leaning forward to where his finger was and licking over
his entrance.
“Shit, Dean!” Sam clasped his hands over his own mouth.
Dean giggled, swiping his tongue again for another taste. Hm. Almost tastes
like sea salt. A bit sweet too. Dean swirled his tongue around the ring,
pressing his fingers at the edges to pull slightly as he pushed inside. Sam
moaned behind his hands.
In between the licks, Dean’s fingers slowly pressed their way inside Sam’s hole
one at a time. He couldn’t help breaking his bravado and asking nervously, “Is
this alright?”
Sam nodded his head frantically, pulling his hands apart to shout a quick “Yes,
yes, yes, keep going or I’ll kill you I swear, Dean!” before covering his mouth
back up again.
Dean immediately complied, using his tongue to ease the two fingers in and out
of him. He pulled his mouth away to watch them disappear inside Sam and stretch
the rim wider. He slowly pressed forward, listening to Sam’s heavy exhales fill
the room before hitting the bundle of nerves within him that nearly caused
another scream to seep through the boy’s trembling hands.
Dean pressed the spot several more times, carefully adding his ring finger to
the pair and continuing to stretch Sam out. He kissed Sam’s inner thigh and
gave out a small coo, hoping somewhere in his head that that would tell his
 baby brother that he was doing a brilliant job taking his fingers, that he was
so fucking beautiful this way.
“D-Dean, I swear to god if you keep going like that I’m going to come and
possibly die.”
 “Alright, alright,” Dean slid his fingers out and sat up, looking down at
Sam’s quarter-opened eyes and lifting his hand to his mouth to suck off. He
smiled impishly at Sam immediately shutting his eyes again and uncontrollably
thrusting of his hips into the air.
Dean huffed, suddenly feeling the return of the heavy and almost painful weight
of his own cock left unattended. “Alright we need lube of some kind,” He patted
Sam’s thigh and snickered, “I’ll be back.”
Sam just kept his eyes closed and legs spread open- too tired and on edge to
even bite back with a retort. He could feel how slick his entire crotch was
thanks to Dean. Jesus Christ, he felt dirty. And absolutelyamazing.
The lack of vision for Sam just left him with the dip of the bed. The feeling
of warmth between his legs followed by the sounds of lube being slathered onto
Dean’s cock. And then the sharp whistle of air emitting from his big brother’s
nose. Sam could feel the slippery skin of Dean’s head beginning to enter him,
stretch him easily as he took deep breaths and let his entire body go to the
feeling of giving himself up to Dean.
“Shit, you’re tight, Sam,” Dean said through gritted teeth. He leaned over
Sam’s chest, pulling one leg around his waist while the other got hiked up over
his shoulder. He continued to slowly ease in, fighting the urge to implode as
he moved. Sam was cutely biting his lip again as his flush face grew brighter.
Dean’s eyes were fixated on him, his own mouth opening slightly to the site of
Sam’s tongue licking over lips that were dry from panting and currently forming
the words, “F-fucking move already, you jerk!”
Dean’s hips rolled until they were completely flush against Sam’s as- both of
them moaning brokenly. He started up the rhythm, hands tightening around the
legs wrapped around him as he plunged deeper inside. Sam’s hands returned
quickly to his mouth when Dean hit his prostate, the muffled scream being high-
pitched and entirely needy. Dean groaned to the sound of it. “Yeah, oh, fuck
yeah,” he snapped his hips faster, feeling the build of his orgasm begin when
Sam started pushing himself down on his cock. The slap of their skin colliding
echoed throughout the room- complimented by the synchronized gasping between
them. Dean leant down and kissed Sam just as he came, filling him up the moment
the boy’s tongue traveled inside his mouth. Dean bit Sam’s lip and whispered
against it, “Now it’s your turn to come for me. Come for me, Sam.” He reached
down and took Sam’s cock in hand, tugging on it only twice before a scream was
heard and come flew through his fingers onto both of their chests.
Dean kissed him again before pulling back and smiling at his totally blissed
out brother. He began to pull out of Sam before hands grabbed onto Dean’s
forearms.
“Don’t…” Sam said wearily.
“You’d probably want me to clean you up before we’re both stuck together like
this forever.”
“S’ no problem with that.”
Dean let out a small laugh, “You have a test tomorrow.”
Sam opened his eyes and smiled tiredly up at him, “No, I don’t.”
“But you were studying-”

“C’mon, first night off the job and you thought I’d waste it studying? If you
couldn’t even catch on to that, no wonder you failed high school.”
Dean grabbed a pillow from behind him and hit Sam’s head, “You bitch!”
Sam giggled into the bed.
