Summary
     Sammy's seen the way Dean can take it. He knows that Daddy's too big
     and that he's too small, but he can do it; he just needs a little
     help.
Notes
     Thanks be to CallMeB and Oddfront for this_wondermous_prompt from
     their Adopt Me? Please? series, which inspired me from the moment I
     clicked. I hope this fic does your imaginations justice :)
     WARNING: Little Sammy is extremely underage in this fic (a mere ten
     years old) as he attempts to take John's cock for the first time.
     There are mentions of very young John/Dean frottage as well, though
     he's fourteen here. If you continue to cling to nonexistent morals,
     please turn away now. This fic contains graphic depictions of
     underage incestual smut and is not for the meek or mild.
     Enjoy :)

Sam’s tongue darted out to wet his upper lip.
With nimble fingers, he slowly slid the zipper of John’s pants down and
unbuttoned his jeans, checking once again to make sure he hadn’t woken up. A
quiet snore touched his ears, and Sam continued until the jeans were open as
wide as they could go. He smiled when he saw bare skin beneath parted denim, a
small tuft of coarse hair that he knew he’d be able to feel later.
Sam slowly grasped his father’s cock and worked if from its confines. John
grunted with the first touch, but he didn’t wake, so Sam didn’t stop. His brow
creased, and he pursed his lips at the sight of his father’s flaccid cock.
Staring for only a split second, he leaned down and tasted the slit.
John’s cock was warm against his tongue, and it twitched familiarly against
him. A few slow pumps of his hand and it began to harden in his grasp, making
Sam smile proudly. He licked the tip again, tasting sweat and skin, the same
taste as the smell of his father’s musk. Training too close to him and sleeping
in the same room and spending hours trapped in the confines of the Impala had
given Sam plenty of opportunities to accustom himself to the smell. It was
something he craved. It was something he couldn’t get out of his head, no
matter how hard he tried.
And now, it was his. He could lean down and take the cockhead into his mouth,
suckle it like he could his own thumb. He could swallow down the small beads of
precome that dripped from his cock, aroused now even in sleep. He could slide
his lips down the shaft of his father’s rapidly swelling cock until it took up
all available space in his mouth, and then he could push deeper until he was
gagging so good on it while he forced it into his throat because nothing could
fill him up like his daddy could, and now he would have the opportunity to do
everything he wanted because John couldn’t say he was too little or too still
not ready.
Sam fisted his father’s cock in time with the bobs of his head, forcing it
further down his throat with every stroke. He pulled back just enough to catch
his breath, but he couldn’t keep himself away. His tongue traced the smooth
underside of the cockhead, down the swollen shaft, tonguing at the bulging vein
that pulsed in time with John’s heart.
Heat poured from the cock in his hands, and lust poured from Sam’s mouth as he
took his father again.
John grunted and moaned. His hips thrust up in sleep, seeking more of the wet
suction of Sam’s mouth. A hand to the back of his head forced Sam in deeper,
but he didn’t mind it. If anything, he was thankful for the help. It was so
much easier when he was forced to take it. He wished that his father was more
like this when he was awake.
Instead of the light touches and nods of encouragement, he would rather have
had this, the slow fucking of his mouth as John’s cock filled him up
completely, making him gag, spit pooling in the corners of his mouth, the quick
drag and pull of skin forcing his jaw wide, forcing him to remember not to bite
down.
He and John moaned together, and Sam didn’t care so much about being quiet. He
gasped and spluttered as the hand on his head became more forceful. John thrust
quickly into Sam’s mouth, but Sam knew the twitch of his hips like he knew his
middle name. His father was close, so he pulled away.
Sam drew his head back, off of John’s cock. Still half-asleep, John wasn’t able
to guide him back down. One hand still leisurely stroking his father’s cock,
Sam kissed up and down the shaft, his touches too light to bring John any form
of relief. The throat fucking was nice and all, but that wasn’t what Sam was
after. He’d spent hours preparing himself; he wasn’t going to let that all go
to waste.
“Sammy?” Dean whispered into the dark.
Sam contemplated not answering him, but he figured that Dean would just get up
and start looking for him if he didn’t. “Yeah?”
“What are you doing?”
“Nothing.” Sam grimaced at the obvious lie. He’d been trained to lie his entire
life—to teachers and friends and anyone who came snooping around. There wasn’t
a single person on the planet he couldn’t lie to… except for Dean.
“Nice try, dweeb,” Dean said, sounding more awake than he had just seconds
before. “What are you doing really?”
Sam sighed. “Playing with Daddy’s cock,” he admitted.
Dean chuckled. “Can’t get enough, can you?”
Sam didn’t deny it. “Dean?” he asked instead. “Why won’t Daddy fuck me?”
“’Cause you’re too small still, Sammy,” he said. “Gotta wait ‘til you’re
bigger.”
Sam pouted. “That’s not fair. Daddy was fucking you when you were ten.”
He heard a rustle of sheets and the small patter of footsteps in the too quiet
motel room. Dean’s hand rand down his back, eliciting tiny shivers that had
Sam’s arousal coming back to him tenfold.
“That’s different, Sammy. He wants to be careful with you, baby boy. Both of us
do.”
Sam gasped and leaned into Dean’s touch. Hands roamed his bare torso, slinking
lower and lower until his own hard cock was rubbing against Dean’s open palm.
Sam made a choking noise in the back of his throat, his father’s cock
completely forgotten in the heat of the moment.
“That’s right, Sammy,” Dean coaxed. “Feels good, doesn’t it?”
Sam nodded, hips canting into the touch.
“Your little cock is so hard that it’s gotta hurt, but it’s still getting
swallowed up by my hand. Just a couple of inches right now, but you’re gonna be
huge. You could stay in me all night, and I wouldn’t even feel you.”
Sam keened at Dean’s words. His cheeks flushed in humiliation, but that didn’t
stop the slow thrusting into Dean’s calloused hand. Every small tug on his cock
had him panting in short gasps, trying to get moremorefuckmeplease because he
was so damn close.
“Please, Dean,” he whimpered, but Dean just chuckled.
“Thought you wanted Daddy’s cock,” his brother whispered in his ear, and that
was all it took for Sam’s mind to scream out a litany of curses—fuck, Dean,
fuck, shit, ohgodohgodohgod—as he came dry from Dean’s hand. “Fuck, Sammy,”
Dean whispered in awe at the sight of his brother, panting and sweaty with the
force of his orgasm.
“Still wan’ it, Dee,” Sam murmured. His mouth was unable to form the words
without a display of will. “Wan’ in me.”
Dean ran a soothing hand over his bare thigh, up and down, grounding him with
the touch. “We have all night, baby boy,” he whispered. “No need to rush.”
“Really?” Sam smiled. The afterglow of his orgasm painted the entire room in an
array of pleasure. That Dean would actually help him take his daddy’s cock
wasn’t even something he’d considered.
“Yeah, Sammy. Don’t want you getting hurt. Need to help you through it.”
Sam smiled lazily and closed his eyes as he pulled his big brother into a kiss.
It was slow at first, just their lips pressed together. Soft and supple and
sweet, it was an innocent kiss, testing and tasting, just trying to be closer
for the sake of closeness, of intimacy. Sammy didn’t let it stay that way for
long.
He parted Dean’s lips with his own, just enough to breathe the same air. He
smelled Dean in a way he couldn’t outside of the bedroom. Hot breath on his
lips, moist tendrils that graced across his cheeks with every gasp of his
name—Sammy.
He smiled against Dean’s lips, just breathing him in. He could taste him, so
close but not close enough. Sam angled his head to the side and pressed in
closer, a gentle suction this time and a tangle of tongues.
Dean’s mouth cradled his like a caress, moving achingly slow against him as a
light touch of fingers brushed its way up his spine, glossing over his skin and
leaving a pebbled trail in its wake.
Sammy keened, and his mind turned into an empty abyss that didn’t allow
anything to come to mind that wasn’t his brother’s body pressed tight to his
side, arms cradling him, lips insistent and wanting.
The deep sound of a throat clearing startled him. He broke the kiss with his
sudden flinch. Shocked eyes turned themselves to the noise, and his body
relaxed into guilty realization when he discovered his father’s eyes on him.
Sam grimaced and looked down, ashamed that he’d been caught so off guard when
it was supposed to be him who was instigating things.
“Sammy?” John questioned.
“Yeah.”
“What are you doing?”
He turned and buried his head in Dean’s shoulder. If he hid away, maybe his
father would leave it alone.
“Dean?”
“Sammy snuck out of bed for a midnight snack,” he explained. There was a hidden
undertone of lust in his voice that both of them couldn’t help but catch.
John’s hand trailed down to his cock, still moist from Sam’s mouth, and stroked
once as if testing it for something. “Couldn’t wait ‘til morning?” he asked.
Sam shook his head, nestling himself deeper out of sheer embarrassment.
Dean chuckled.
“Sammy,” John chided.
Sam blanched. “I –I just wanted to take it like Dean does.”
The bed shifted underneath him as John sat up. “You’re not big enough yet,” he
said.
“That’s not fair,” Sam pouted. “You and Dean did it all the time when he was
ten, and I’m almost eleven.”
John didn’t touch Sam like he touched Dean. There were the light kisses on his
lips and the stray finger in his hole, but it was nothing compared to the way
his cock seemed to split Dean open in the dead of night, low moans and harsh
panting that would have been heard all the way down the street if it wasn’t for
them taking enough precaution against it.
Sam pouted as he thought about it. It was Dean who’d invited him in the first
night when he woke up to the sound of John grunting from the opposite bed. Come
on, Sammy, he’d said. I’ll make you feel real good. Trust me. His daddy didn’t
tell him no, but he never took it as far as Sammy wanted, never filled him up
all the way like he did Dean.
“Never mind,” Sammy mumbled, extending his leg to touch down to the floor
before climbing of the bed. “I’m just gonna go to sleep.”
Sam was yanked back on the bed by a strong arm around his waist. John pulled
Sam onto his lap, and Sam couldn’t do anything but bury his head in his daddy’s
chest and hope that whatever he said was relatively painless.
“It’s not that I don’t want to, Sam,” John began. “But you’re still too tight.
Dean opened up real quick when he was your age, but your hole’s too small to
fit my cock in you.”
Sam’s chest tightened with the realization that his father was telling him once
and for all that he wasn’t as good as Dean.
“There’s nothing I want more than to take you, Sammy.”
Some of the ache went away with those words.
“But I don’t want to hurt you.”
“Please, Daddy?” Sam practically begged. “Please?” he hugged his daddy closer,
taking care to press himself down enough to stimulate John’s cock.
Blood pulsed through the already hard length, and it somehow swelled larger
under his youngest son. It pressed against the crease of Sam’s ass, fitting
almost perfectly.
“Okay, Sammy,” John conceded.
Sam smiled and righted himself in his father’s lap, straddling his hips and
holding himself chest to chest with John. Impatient now that he knew what he
was going to get, Sam reached back and stroked John’s cock. Precome dribbled
from the head, and Sammy used it to slick his way, smearing it down the shaft.
Like this, his daddy’s cock felt large, too big like they’d said, but he didn’t
back down.
He pressed the tip teasingly to his hole, feeling more sensitive because of his
well-hidden trepidation. John gasped, but didn’t press in. He held his hips
down, away from Sam’s tight hole, and waited until he was ready.
“That’s it, Sammy,” Dean murmured in his ear. The hot tufts of breath made him
shiver.
Sammy swiped the leaking cockhead over his hole, shivering whenever it pressed
against his perineum. The four tiny fingers he’d stuffed inside of him earlier
were nothing compared to what his daddy’s cock would feel like filling him up.
He was sensitive inside, would writhe and moan on just one finger, and the
anticipation of feeling the pulsing member against his prostate had him
practically trembling.
“Go ahead, baby boy. Put it in. Daddy’s waiting, and it’ll feel so good with
him stretching you so wide.”
Sam pressed the tip inside and let out a choking sound. His eyes clenched tight
of their own accord as he was stretched further than he’d ever been before. It
was more painful than he thought it’d be, but the pleasure was still there.
“Oh, god,” he gasped. “So full.”
“And you’re not even an inch inside yet, Sammy. Just imagine what it’ll be like
when Daddy fills you up for real.”
Sam’s blunt fingernails dug into John’s shoulders, too short to do anything but
leave tiny half-moons in his skin as Sammy attempted to sheathe John’s swollen
cock in his too tight channel. His thighs shook with the effort of taking his
father inside of him, trembling with his weight, too out of it to control
himself, so John held him by the thighs and guided him down another inch, then
two.
“Daddy’s not even halfway yet. Just gotta take it, Sammy. Just a little more.”
His hole was strained from taking the width, more so than it had ever been
before; not even his daddy’s fingers had reached this deep inside of him. John
lifted him up by the curve of his ass, helping him now. Not wanting to rush,
John brought him down slowly, fucking Sammy on the first few inches of his
cock. Lube from Sam’s earlier attention slicked the way, but it still wasn’t
enough for him to take the rest.
“Dean,” John said, and order in his voice. “Lube.”
Through the thick smog of pleasure, Sam barely registered the words, and he
didn’t understand them until a hand, warm and slick, was pressing against his
stretched out hole. The cock twitched inside of him, making him gasp while Dean
coated it.
“Gonna make it nice and slick for you, Sammy. It’ll be easier for you.”
Sam’s cheeks burned with shame. He’d seen the way Dean took their father’s
cock, seen the way he fucked himself back into every hard thrust, unable to
keep himself from moaning out loud, even screaming sometimes when the angle was
just right. He’d seen how Dean’s eyes would roll into the back of his head and
how his spine would arch in pleasure as he came. He wanted it like he wanted a
cold drink on a hot day. It was a compulsion, one that he needed more the
harder he tried to ignore it.
Still, the cock inside of him was impossibly large, forcing him wide just to
accommodate the first few inches. He couldn’t even imagine what it would feel
like when it was completely inside of him.
“Gonna feel so good, baby,” Dean whispered, and that was all Sammy needed to
continue his slow descent.
He heard John’s groan as he took another inch inside him. Twin breaths hit both
sides of his neck, Dean whispering filth on his left and his daddy pressing
tiny kisses to his right. Calloused fingers stroked his thighs, calming him
enough to slide down another inch.
John’s mouth pressed right at his ear, small shivers crawling down his back
with his daddy’s words. “That’s it, Sammy. You’re doing so good.”
He couldn’t deny the pleasure that coursed through him, but Sammy whimpered at
the stretch. It was too much, too big, too deep, too sensitive inside. His hips
twitched with the stimulation against his prostate, pleasure masking the pain,
but not enough.
“It’s okay, Sammy. Don’t worry. Big brother’s gonna help you. You ready, Sammy?
Ready to feel Daddy all the way inside you?”
Sammy nodded, still wanting it, wanting to be able to take it like Dean took
it.
Sam whined, a high-pitch keen, as Dean took him by the shoulders and forced him
down on the last few inches of his daddy’s cock. He sobbed with the sensation,
but the pleasure that coursed through him, even with the ache of being
stretched too far too fast, made his tiny prick twitch as he came completely
dry just from his father’s cock in his ass.
“That's it, little brother. Just keep sliding down Daddy's cock. Feels so good,
doesn't it? Just keep taking it, baby boy.”
His hole rippled with his orgasm, and he couldn’t help the small twitches of
pleasure that ran through him when John lifted him up and dropped him down on
his cock again and again, the head skimming past his sensitive prostate.
Completely spent, he went limp in John’s hold, letting John fuck himself into
his tight hole.
“God, Sammy, look so fucking hot taking daddy’s cock.”
John filled him completely, making his prick harden again quickly with every
thrust inside of him. It was so deep, Sam could practically feel it in his
stomach, fucking into him hard and fast now that his hole was stretched enough
to take it.
Through lidded eyes, he caught the green of Dean’s, peeking at him over their
daddy’s shoulder. His brother’s hands wrapped around John’s side to cling to
his chest, and Sammy just knew that Dean’s cock was flush against their daddy’s
back, getting off on the friction of John fucking into his tight hole.
Dean continued to murmur filth, but what Sam could hear was unintelligible from
either Dean’s own descent into ecstasy or Sam’s inattention. His thoughts were
muddled, and what wasn’t the slow rise of his orgasm or the large cock
thrusting into him or the feel of his daddy’s coarse hair scratching against
his scrotum or his prostate screaming in pleasure from his daddy’s cock
practically fucking itself into his stomach, was lost in a sea of overwhelming
pleasure.
“Daddy,” Sammy panted, grinding himself on his daddy’s cock. He moaned loudly,
the pain but a memory compared to the sparks of sensation running through him.
“That’s it, baby,” John cooed into Sam’s ear. “Doing so good, Sammy.”
Sam came again with a cry, practically sobbing with the force of it as his
daddy continued fucking him through his dry release. A wetness spread through
him, filling him up even more, and Sam knew that his daddy came inside of him.
John grunted as he came, and Sammy swallowed the sound with his mouth, tasting
his daddy’s moans of pleasure.
Dean wasn’t far behind.
“Ohgod,” he whispered. “Fuck, Sammy. Sofuckinghot.Ohgod.”
Sammy gasped in air as if he hadn’t breathed in years. For all he knew, he
hadn’t taken a breathe since the first inch of his daddy’s cock disappeared
into his now fucked out hole. But John and Dean’s were just as ragged, so Sammy
just smiled and panted in time with them, lost in the sheer joy of finally
getting what he wanted.
His father’s cock slipped from his ass, and come oozed out, dripping down his
thighs. He made a disappointed noise in the back of his throat, but John was
there, wiping it up with his fingers and pressing it back inside. After the
constant pressure of his daddy’s cock inside him, he felt empty.
“Don’t worry, Sammy,” Dean told him. “We’ll get you a plug, a big one like
mine, keep you stretched out all the time just like you want it.” 
Sam smiled lazily. There was no doubt in his mind that nothing could ever take
the place of his daddy’s cock, but a plug wasn’t a half-bad idea.
