Summary
     Jensen can hear his step-brother jacking off behind the door whenever
     he and his girlfriend have sex in his room. He doesn't mind, though.
     In fact, he thinks he might invite Jared to join them.
     (Jared's 16, Jensen is probably 18)
There’s a wet sound outside the door, a shuffling of flesh that Jensen
recognizes from his own warm nights as a teen with too many chemicals sluicing
through his body. He’d been too busy with the writhing girl in his lap to
notice it before, but he thinks it’s been there for a while. He also suspects
this isn’t the first time that his stepbrother has stood outside his door,
jerking off to the sounds of Jensen fucking his girlfriend.
Leaning forward, Jensen flicks his tongue over Danneel’s nipple while sharply
thrusting up with his hip, punching out a sudden, loud moan that’s echoed
quietly out in the hallway. He grins around the dime of pink skin in his mouth,
letting his teeth brush over the sensitive nub as Danneel grabs his head and
rocks harder. Back and forth in his lap, tight around his dick. Both of them
suddenly needing to finish this nownownow.
Not twenty feet away, he can hear Jared. Soft, puppy-cry pants against the
wall. Slick sound of his hand working around his cock. The muted noise slips
like lighter fluid into Jensen’s veins, spark-lights him up from the inside,
squeezes him like a gunshot as he shoots hot and wet into the beautiful, dark-
haired girl on top of him.
Seconds later, he hears the rustle of Jared adjusting his pants and padding
back down the hallway. He imagines the rose-colored stain on the boy’s cheeks,
floppy hair obscuring hazel eyes as he shuffles back to his room, gauzy webs of
come caught between his too-long, wide-spread fingers. Relief pouring cool
across his skin at the false belief that he hadn’t been caught.
Danneel collapses against Jensen, humid breaths against his chest.
“Was that your brother outside?” she asks breathlessly.
Jensen shrugs.
“Yeah. Think so.”
*&*
At the dinner table the next day, Jensen can’t stop staring, wondering how long
his stepbrother’s been eavesdropping outside his door. The scrutiny makes Jared
uncomfortable, and he keeps ducking his head, peeking up at Jensen through long
bangs, trying to hide blood-filled cheeks.
Waiting until the boy’s slanted, prism-bright eyes are hesitantly fixed on him,
Jensen slowly brings his spoon to his mouth, licking up nonexistent drops of
stew, tracing the edge of the metal utensil with as much obscenity as he can
get away with while their parents are sitting on either side of the table.
Eyes wide, Jared stares with helpless, snake-charmed fascination, cup of water
suspended in front of his lips while Jensen’s tongue swirls around the dipped
metal. When Jared finally tips back his cup, takes a small, parched swallow,
Jensen lets the spoon tug down his full bottom lip, stretching out the pink
muscle in strip-tease slow motion. With a wet garble, Jared chokes, surges
forward and tries to cough out the liquid threatening to go down his lungs.
His mother leans over, murmuring a few soothing words as she rubs his back,
waiting until he manages to clear his airway and resumes breathing normally.
But when he looks up to see Jensen’s wide grin, Jared jumps to his feet,
hurriedly excusing himself from the table and running to his room. Their
parents look up curiously at his quick exit, but he’s newly sixteen, and
they’ve long since been used to the unpredictable teenage mood swings of both
their sons.
*&*
Two years have passed since Jensen and his dad moved in - Mr. Ackles into his
new bride’s marriage bed and Jensen refitting the guest bedroom with plaid
sheets and posters of classic rock covers and Cowboys logos. It had been an
easy adaptation. Jared had been a fourteen-year old kid who wore his fractured
heart on his sleeve, recklessly offering up the safety-pin-and-duct-taped organ
before they’d even finished unpacking. It was obvious from the beginning that
Jensen and his dad never even had to try with him. Hero-worship for his new
father and brother was almost instantaneous.
Jensen, for his part, had been relieved to turn some of the only-child
spotlight away, happy to have someone else to blame when things broke or chores
weren’t done. It helped that Jared always had his back; could weave perfect
cover stories and distract their parents from Jensen’s stupid teenage antics
whenever necessary.
Jensen had never wanted a brother before. Now he can’t imagine his life without
one.
*&*
Saturday mornings for Jared and Jensen usually mean video games down in the den
on the overstuffed couch, the only piece of furniture left from Jensen’s old
house. Jared octopus-sprawls every which way, stretching out muscles
perpetually sore from neverending growth spurts. He’s right on the cusp of
fitting into his own skin, smacks his head on overhead lamps and breaks pencils
when he grips too hard. But sometimes he’ll find his groove — jogging across a
basketball court or flipping on their backyard trampoline — and there’s an
undeniable grace to the way he moves his body, the way the muscles of his
thighs shift and tighten. He’s beautiful now, all baby cheeks and coltish
limbs, but Jensen thinks the boy’s going to be stunning by the time he finishes
growing.
Currently, he’s curled up on his side while Jensen leans back, bow legs spread
wide and knees knocking into his brother’s. Their shoulders tend to
unconsciously press against each other when they’re in the middle of a good
tournament, too excited to notice or care about the lack of space between them.
When Jared thoroughly trounces Jensen in their last round of Smash Brothers, he
turns a smug grin towards Jensen. Dimples prick his cheeks, and part of Jensen
wants to poke a finger in them, maybe the tip of his tongue. Earlier teasing
aside, Jensen’s unsure of what he wants, has barely gotten used to the concept
of Jared as a brother. It suddenly dawns on him how much he actually likes
Jared. How easy it was for Jared to draw Jensen out of his shell, relax his
guard. Slip into place into Jensen’s life like he’s just tucking himself back
into bed.
“Cheater.” It’s an empty taunt, one that Jensen doesn’t mean. A gunpowder word
to ignite a trigger reaction. He knows it doesn’t take much; Jared’s always
been competitive, throws his whole self into everything he does.
Slanted eyes narrowed, Jared scoffs and says, “For all ten rounds? Admit it,
Ackles. I’m just faster on the draw than you, old man.”
Jensen’s controller falls to the ground and he throws an arm back, hooking it
around Jared’s neck in a tight headlock. He’s surprised when Jared doesn’t pin
down easily, swears that Jared used to be so easy to toss around just a week
ago. He can feel virgin-new muscle beneath his hand as Jared knocks them both
off the couch and rolls them across the floor.
This isn’t their first fight, not by far. But it is the first time that Jensen
no longer has the clear advantage; that he has to fight to keep the upper hand
as he straddles himself around Jared’s back and tries to hook Jared’s arms
back. The kid, however, has other plans. Manages to twist a leg underneath
himself and shove it around one of Jensen’s calves until they both flip.
In a surprise drop of gravity, Jensen finds himself successfully and firmly
pinned to the ground, looking up into Jared’s proud and grinning face less than
a foot away from his own. Jared doesn’t even have the decency to look surprised
at his win.
“Someone’s been eating their Wheaties,” Jensen grumbles in fake irritation. He
wiggles around, trying to dislodge his brother from where his legs are
bracketing Jensen’s hips. “C’mon, man, let me up.”
“You admitting defeat?” Jared asks triumphantly, refusing to budge, hands
clamped down tight on Jensen. His face is flushed from the exertion of the
fight, hair ruffled and falling into his face, and Jensen has a sudden flash of
Jared in a few years. Taller, older, stronger. But still with that beaming,
little-kid grin on his face.
“No,” Jensen answers as something warm pulses behind his heart. The pressure of
it aches in a good way, pushes up all sorts of bad ideas with good intentions
into his head. Or maybe it’s the other way around. It turns him reckless,
taking the affection he feels for the kid and twisting it, corkscrew turns into
his chest until he surges up, pressing his lips against Jared’s surprised
mouth. Warm, wet movements while Jared stays still in shock. The boy’s mouth
falls open wider, traces of fruit loops and milk on his tongue.
Jensen barely gets a taste before Jared leaps off of him and runs up the steps.
The sound of a door slamming shut and Jensen’s alone on the ground, sugar in
his mouth and rug burns on his elbows.
He has a feeling it wouldn’t take much to break the kid.
*&*
A few days later, their parents leave on a joint business trip. They both work
for the same firm, had met and fallen in love on the job. It had been a scandal
at the time, water cooler gossip and mounds of HR paperwork, although it’s old
news by now.
Their taxi is two blocks away when Danneel pulls up to the house, bass-drum
sashays up to the front door in her cut-off jeans and tight AC/DC t-shirt. She
doesn’t bother knocking. She meets Jensen in the kitchen with a hungry kiss,
fingers sliding to the front of his jeans, playing with the edge of his belt.
Jared watches them from the living room, popcorn bowl in his hand and Cowboys
game on the TV. Pixie eyes darting towards them then quickly looking away when
Jensen turns his way.
With a smile, Danneel grabs onto Jensen’s belt loop, leading him by the front
of his jeans into his bedroom.
*&*
The door is left cracked open invitation. Bed creaks and breathy gasps echo
down the hallway, loud enough to reach the living room, possibly loud enough to
disturb the neighbors. Based on the knowing look Danneel gives Jensen when
they’re collapsed in bed, she hadn’t been fooled, knows exactly what he’s up
to. But she seems completely game for whatever Jensen’s got in mind.
Jared never shows up, though.
The second night, however, Jensen knows he’s there. Quieter now, trying to be
even more discreet. But Jensen’s been listening for him, and the old house
doesn’t keep secrets well. The floorboards creak just outside Jensen’s door,
sharp tattles that make Jensen perk up. He puts his hand on Danneel’s head, and
she pauses with her mouth around his cock, pulls back and rubs at her wet mouth
with the back of her hand.
“Jared?”
Jensen nods, and she grins, her eyes flicking towards the door.
“Come inside, baby boy,” she coaxes. “You can see better from in here.”
Jensen can practically see the boy shifting on his toes behind the wall,
hesitant, nervous energy. Finally, the door creaks open just wide enough for
Jared to slip inside, hands and back clinging to the wall.
“Nuh-uh,” Danneel says softly, twisting her body around so her back’s against
the edge of the mattress. “Come here. Come closer.”
Jared looks at Jared before moving, looking for some kind of confirmation that
he’s wanted, that this isn’t a castigation or a joke. When Jensen nods in
affirmation, Jared pads across the floor, falls to his knees when Danneel
motions him down.
Her hand is still circled around the bottom of Jensen’s hard, dripping cock,
and Jared’s eyes flick to it several times. Back and forth between the wet
organ and Danneel’s face.
“You wanna know what it tastes like?” she asks, smile on her puffy, red lips.
Jared’s mouth falls open, tongue swiping at his mouth as his eyes cut to look
at where Jensen’s still hard. He nods.
Fingers softly tracing the boy’s jaw, Danneel coaxes him forward so she can
kiss him, letting him taste the glossy precome edging her lips and tongue, all
filthy wetness that echoes against the walls. When she pulls away, Jared’s got
a dazed, blissed-out look on his face, and Jensen hides a grin because he knows
the feeling.
“He’s been waiting for you,” Danneel says, softly, turning Jared towards
Jensen, urging him between his thighs. “Go ahead and ask. He wants it.” She
whispers more directions in the boy’s ears, and Jared blinks a few times, blood
and heat rushing all over his body until there are red splotches all across his
cheeks and neck.
“Jensen.” He looks up, eyes wet and pleading. “Please. Please, can I suck your
cock?”
“Fuck,” Jensen mutters, and he has to reach down and tug hard on his balls,
holding himself off from shooting all over Jared’s soft face. Voice husky, he
nods, reaching out to slide a hand into Jared’s hair. “Yeah. Want your mouth on
me, sweetheart.”
Danneel plucks off the kid’s shirt first, tossing it across the room and then
cocooning herself around Jared’s back while he leans in.
Jared’s a virgin; all cat-feet hesitant as he leans between Jensen’s thighs.
But he knows what he wants. Wrapping a hand out around Jensen’s cock, he parts
his lips around it, eyes half-lidded and so, so grateful. He gives a small
shiver when Danneel’s tongue traces the shell of his ear, her soft voice
breathing out encouragement. Over the kid’s slurps, Jensen can faintly hear
Danneel’s rich voice directing Jared to tongue around the head, jack harder
with his hands, roll Jensen’s balls around in Jared’s pretty long fingers.
Leaning back, Jensen closes his eyes, focusing on the warm suction of Jared’s
mouth, the smooth feel of his hand around his dick. He’s just starting to feel
that build-up of pressure when Danneel pulls Jared back, kisses his full lips,
and tells him to take the rest of his clothes off and sit on the bed.
“You can play again when I’m finished,” she promises Jared as she curves her
back against Jensen’s chest. She reaches between her legs to slip Jensen inside
where she’s all slick wet and pulsing heat.
Obediently, Jared strips down and kneels on the bed, watching with wide eyes as
Jensen’s hands grab onto Danneel’s hips, helping her pump up and down.
“C’mere,” Danneel orders in a jolting voice, reaching out to grab Jared’s hand.
Jensen can’t see where she places it, but it disappears somewhere below her
belly, causing her to gasp and grind in circles. “Right there. Keep going,
baby. So good.”
Jensen’s surprised he’s even lasted this long, overstimulated for what’s felt
like hours. His hips punch up one last time, digging in as deep as he can until
his insides crack open and he spills long and hard into his girlfriend.
Gasping, he wraps his arms around her belly, sucking a mark onto her shoulder
while a cocktail of pleasure chemicals saturate deep into his brain. Distantly,
he can feel Danneel rocking a few more times before she tenses then spasms into
her own orgasm.
After a few seconds, she turns in his arms, pressing a couple kisses to his
lips. Jensen can hear Jared whimper behind her, soft and needy, and he laughs
quietly.
“We didn’t forget you, little brother,” he says while Danneel grins and
stretches herself out of Jensen’s arms. “Lie back.”
Danneel guides Jared back, arranging him across the rumpled bedcovers. His hair
splays against the sheets in angelic, curling formations, and Jensen can’t
resist leaning down to press a small kiss to Jared’s lips, which he hungrily
leans into even after Jensen pulls away.
“Hold onto your knees,” Jensen instructs with a smirk as he folds Jared’s legs
against his chest. “Spread yourself open.”
Danneel sits near Jared’s head and runs her fingers in swirling patterns across
his chest. Figure eights and loops that make Jared’s eyes flutter back. It’s
enough of a distraction that Jared almost forgets what position he’s in — until
Jensen presses a wet, slick finger around his hole.
Jared’s eyes burst open, but Danneel’s already leaning down, murmuring soothing
things while Jensen rubs around the rim of the boy’s asshole. “Doing so good,”
she says approvingly.
“What —” Jared starts to say, but Danneel chooses that moment to flick her
thumb over a nipple, and Jared sucks in a sharp breath.
“Think you can take my fingers?” Jensen’s voice has gone down a few registers
in his eagerness, and he presses against the rim, testing the give.
“I don’t know,” Jared says, fingers tightened anxiously around the back of his
knees.
“Do you wanna find out?”
There’s a long pause, and Jensen starts to worry, wondering if they’d taken
this too far, if Jared’s having doubts. If all that hero-worship pushed Jared
too fast and far into something he’s not sure about. But then Jared breathes
out, “Yes. God, yes. Please.”
Jensen grins at Danneel who looks as equally pleased. He drips more lube around
his fingers and presses a little harder, waiting until Jared’s finally relaxed
to slip a digit in.
“You take that so pretty,” Jensen praises, because it’s true. A furious blush
spreads across Jared’s cheeks, but he looks pleased in spite of it, preening
under Jensen’s approval. It’s never taken much with Jared. Jensen doesn’t know
what he did to deserve such devotion, but he hopes to God he never does
anything to topple that shrine of sheer, perfect trust.
“Think you can take more?” Jensen presses, and Jared nods eagerly.
Before he adds another finger, Jensen leans in to run his tongue up Jared’s
ballsack, dipping through the middle before flicking his tongue to the side.
Jared starts twisting into the blankets, gasping when Jensen finally runs his
tongue up the underside of his cock.
He teases Jared for a few minutes, small licks and kisses that drive him crazy,
before Jensen finally swallows him down, throat opened wide. While Jared’s
gasping at the ceiling, Jensen sneaks in a second finger, fucking them in and
out of Jared’s hole in time against the rhythm of slurping up and down Jared’s
cock. He desperately wants to know how well Jared would take his cock, but he
can feel how tight he still is. There’s always next time, although Jensen
doesn’t mind the thought of finger-fucking Jared for a while, not when the
boy’s so obviously made for this.
“I’m—” Jared barely gets out before his dick twitches against Jensen’s tongue
and he’s spurting white and hot down the back of Jensen’s throat. Jensen
swallows hard, sucking Jared dry before he pulls away, letting his fingers pop
out as he licks Jared clean.
While Jared’s still catching his breath, both Jensen and Danneel slide in on
either side of him, Danneel snuggling in tight under his arm while Jensen
throws a leg over Jared’s and scoots in close. He pushes a hand behind Jared’s
neck, idly stroking through the soft hair.
“Good?”
“Uh… yeah.” Jared looks dazed, blinking a few times and neck swinging as he
glances at them both. “Is that… oh god. What was that?”
“Shh…” Danneel says while running her hands across Jared’s shoulders, up and
down in sleepy circles. “Does it matter? We want you here. Stay.”
“Please,” Jensen adds in a low voice, fingers still threaded in Jared’s hair.
“Okay.” Jared gives them a slow, shy grin. “I... I'll stay.”
