Summary
     Summary of the Original Prompt: AU where Jimmy Novak died when he was
     young, so Castiel is forced to go back in time and get a younger
     version of his vessel. He is still a badass angel, but he's
     constantly mistaken as Dean and Sam's son/nephew. Dean has a huge
     issue with his attraction to Cas considering the body he occupies,
     but one day the LUST comes to a head. Dean pulls Cas onto his lap and
     kisses the crap out of him and it is enthusiastically reciprocated.
Notes
     Full, copy and pasted original prompt:
     AU where Jimmy Novak was killed in his early teens so when Castiel
     needs a vessel he had to go back in time to get a much younger Jimmy
     Novak (10-14). Cas is still a bamf angel of the lord he is just
     constantly mistaken as Dean and Sam's son/nephew. Dean has a huge
     issue with his attraction to Castiel considering the body he occupies
     but one day the LUST comes to a head. Dean pulls Cas into his lap or
     picks him up and kisses the crap out of him and it is
     enthusiastically reciprocated.
     While Dean is working Cas towards his very first orgasm one of them
     slips out a daddy kink. Either Cas saying daddy please or Dean saying
     daddy's got you. The other goes a little crazy hearing it. From then
     on Dean isn't as uncomfortable about the age of Cas' vessel or even
     that people think Cas is his kid. Though sometimes Cas is naughty in
     the way he calls for his daddy in public and Dean spanks him later
     for being a naughty boy and turning Dean on in public.
     ___
     Warning! This fic does feature underage sex involving Cas being in a
     thirteen year old's body !

***** Daddy's Got You *****
This vessel was far from what Castiel had wanted, but it was what was bestowed
upon him. Jimmy Novak would be a tall and strong man, it was a crime in its own
that he never lived to see the day he’d turn fourteen. When the teenager was
thirteen years old, his life was stolen from him in a nasty car crash. The
problem was that Castiel needed Jimmy to be his vessel… at any costs.
 
That being said, he went back in time and claimed the boy. For being so young,
Jimmy was very religious and willing to comply and become a part of heaven’s
plan. Even though Castiel’s true form was huge, and he was billions of years
old, he managed to pack it inside of a tiny, 5’5 thirteen year old. He did not
age while in the vessel, remaining to look thirteen.
 
When he raised Dean from perdition and crossed paths with him the first time,
the man thought it was some kind of joke. A kid raising him? That just happened
to be the case. Years and years past, and even though Sam and Dean were
reluctant to go on hunting trips with such of a young child at first, they gave
in. Castiel was more than his vessel, and he packed quite the punch for being
so small.
 
After over a decade of bonding with Castiel, the Winchester boys had gotten use
to half of the crap that came with the angel being tiny. It was nearly
impossible to go out in public without someone thinking that Cas was Dean or
Sam’s child, nephew, or sibling. They had just given in at this point, going
with what the public thought. It was a lot easier to claim Castiel was their
family member instead of trying to fabricate some other far-fetched story
closer to the truth. That wasn’t the only common occurrence, however. Demons
and monsters constantly underestimated the boy, but Castiel proved time after
time he was a force to be reckoned with. The last thing that Dean had realized
that came with Cas, was a burning hidden attraction. If it wasn’t for the fact
that the angel was in such of a young vessel, he’d want to make out with the
being. Dean hid it as well as he could, but he was romantically and sexually
attracted to Castiel.
 
The trio now sat in an isolated diner, placed right by fields and fields of
corn. Sam had found it weird that the restaurant had chosen such of a deserted
area to set up shop, but Dean was insistent on stopping in after spotting a
sign for pie. Cas and Dean were in a booth together, Sam on the other side.
 
“You’re telling me that it’s not even a little creepy that we’re the only table
here?” Sam whispered loudly after the waitress dropped off their food. It was
no surprise that Cas got a burger, Dean got a pie, and Sam got a salad. Dean
broke off a huge part of his pie, shoving it in his mouth.
 
“Damn, Sammy this is some good pie.” The older Winchester averted, replying
with his mouth open. Sam wrinkled his nose in disapproval.
 
“I swear, it’s like you can’t hear me sometimes.” Sam mumbled, going to start
taking a few bites of his salad. It was decent, but nothing earth shattering.
 
A cheeky grin fell onto Dean’s face, his cheeks hollowed out like a squirrel’s.
“I hear ya, Sammy. I just don’t care that much.” He replied, that same impish
expression on his lips. Sam sighed and dropped it.
 
Castiel began to eat his burger, used to the Winchester’s harmless bickering.
“This burger is phenomenal.” He stated, blue eyes not lifting from the food
even when the waitress came over. The angel hungrily devoured the burger in a
few bites, causing the woman to chuckle a little.
 
“Is everything alright?” She asked, eyes falling on Dean. It was no surprise
that she was bashful around the handsome man. “Your son is gobbling the heck
out of that burger.” A tiny hearty chuckle escaped her lips. “It’s almost as
though you never feed him.”
 
Dean rubbed his neck a little, always being caught off guard by the accusation
of Cas being his child. Sam discreetly kicked him under the table, silently
praying that Dean wouldn’t be stupid enough to try to correct her. “Sure looks
like it, doesn’t it. But damn, everything is alright. This shit is the real
deal.” He motioned to the small piece of pie left on his plate. The woman
giggled and walked off, letting the three enjoy their meal in peace.
 
“Another day in our life…” Sam sighed, mumbling something under his breath. His
preference of a having normal life was thrown out the window by now, it
couldn’t get any weirder than him being friends with a thirteen-year old angel.
 
===============================================================================
 
“He’s been gone for awhile.” Castiel noted, sitting in a motel room alone with
Dean. It had been almost two hours, and Sam was still out at the library doing
research. The angel now sat on the same bed as Dean, who was cleaning out his
guns.
 
Dean let out a throaty chuckle, not bothering to look up from his weapons.
“Well, it’s Sammy. He could probably be at the library for another two hours.”
He admitted, knowing his brother well. “Something tells me he could be there
forever.” The hunter let out a sigh, finally looking up at the angel. Something
stirred in his stomach, realizing that the two were alone sharing a bed. Wrong,
he knew, thinking about all the other activities they could be doing now.
 
“It’s getting pretty hot in here, don’t you think? Don’t you want to take that
trenchcoat off?” Dean asked, only half of his motive being morally right.
Castiel shrugged, not really caring about the temperature one way or another.
“Is it?” Deciding just to please the human, Cas removed his trench-coat and got
up to place it on a nearby chair.
 
Unknowingly, Dean’s eyes traveled down to Castiel’s behind. Now that the
trench-coat was removed, his covered butt was now on display. Even though Dean
tried to shake the thought, all the man could do was think about was asking Cas
to remove his pants.
 
“Dean.” Castiel responded, causing Dean’s attention to be diverted from his
growing lust. He sat down right next to the man. “What do you humans do for
fun?” At one point, the angel could spend weeks just standing still and waiting
in one spot. However, as time went on and he became more humanized, Cas found
himself becoming a little bit bored.
 
It took everything in Dean to not suggest sex. “I mean… well…” Even though he
resisted mentioning sex, he couldn’t help but pull the angel’s tiny frame down
onto his lap. Turning the boy so that he was facing him, Dean leaned down and
locked lips with Castiel. Instantly it hit him what he was doing, so the
Winchester hastily pulled away.
 
Cas paused for a second, far too familiar with what Dean was getting at. The
Winchester wanted him as a romantic partner, and something about that made
Castiel really happy. He considered himself Dean’s guardian angel and best
friend. It made him ecstatic that Dean wished to pursue a relationship with
him. Enthusiastically reciprocating the action, Castiel leaned in and locked
lips with the human. Even though sex wasn’t his forte, something about making
out with Dean and working out all the sexual tension felt so right.
 
Eager hands explored the angel’s outer thighs. He was an angel, he wasn’t
really thirteen years old, right? Dean slipped his tongue past Castiel’s pearly
white teeth, being greeted by a whole new sensation. It was no surprise that
the man was a virgin, and Dean knew by the end of the day, that’d change.
 
They passionately kissed, only stopping to get some fresh air. Castiel put his
hands on Dean’s chest. “What if Sam walks in on this?”
 
Dean reluctantly took Cas off of his lap and started walking to the door. “I
really hope he remembers it, but a long ago, we started this thing where if we
didn’t walk the other to walk in because they were having sex, we’d put a sock
on the doorknob. Frankly, I never saw Sam use the method… but I did, and he
never walked in after we - well, mostly I, came up with that.”
 
A disappointed noise came from the small angel. “You’ve had many romantic
lovers?” A part of Castiel already knew that Dean was very sexually active, but
he liked to forget that.
 
“Sexual partners. Not romantic.” Dean corrected, bashfully rubbing his neck. It
was the first time he wasn’t overly proud of his lack of virginity. “Trust me,
Cas. I was drunk, and just wanted some loving. You’re the only person I’ve ever
wanted through the good and the bad. I want your body, your personality, and
everything inbetween. I want you.”
 
That was a good enough answer for Cas, and he eagerly flung his small body at
Dean. Without hesitation, the man caught the boy and pinned him up against the
wall. This time it was the angel who instigated the long, sloppy kiss. Without
their lips leaving another’s, hands began to work on unbuttoning clothing.
Castiel eagerly allowed Dean to remove his shirt, and he returned the action.
It wasn’t long before they were shirtless, bare chests rubbing against another.
 
Dean’s torso was defined, tanned, and muscled, in contrast to Castiel’s paler,
smaller form. In another universe, Jimmy would grow to be just as big and
muscled as Dean, but that was not the case. Castiel was kinda glad, though,
enjoying how easy it was for the hunter to manhandle him. Neither boys were
paying attention to time, captured in their spell of love. It seemed naturally,
getting down until both were completely naked.
 
“D-Dean…” Cas whispered breathlessly, not used to the constant mouth on mouth
action. “I think I am ready to step up and go to the next part.”
 
Amused by Castiel’s odd phrasing, but willing to comply, Dean wrapped Castiel
around him, carrying him to the bed. He dropped the younger boy onto the
mattress, joining shortly after. “It’s adorable how tiny it is.” The hunter
whispered. Before Cas could ask what ‘it’ was, Dean had already wrapped his
huge hand around the angel’s small prick.
 
Just starting puberty, Jimmy’s dick size was nothing incredible. There was
barely any pubic hair covering the small length. Dean didn’t care, bending down
and taking it into his mouth. Instantly a shaky groan escaped the angel’s lips.
He felt the pleasure forming in his lower stomach, amazed by the sensation.
Human physical pleasure was a foreign concept to him. Castiel’s dick began to
twitch in response to Dean’s warm and wet lips exploring the member. The hunter
licked the slit, causing Cas to twitch a tiny bit. Not stopping, Dean lifted up
the hardening penis with his pointer finger, licking underneath.
 
Not being able to hold back, Cas quickly shut his legs. Dean let out a little
noise, lifting his head up from the crotch. Castiel blushed a tiny bit as Dean
put two huge hands on his inner thigh, pushing his legs obscenely wider. “Cas,
you can’t do that. You’re going to crush me. For a thirteen year old, you have
some slammin thighs.”
 
“My apologies, Dean.” Castiel whispered, not intentionally trying to cause any
harm to his lover. Deciding to try to obey Dean, he held his legs open, giving
the other a straight passageway to his throbbing erection. Being so untouched
for so long, it wasn’t long before he came all over Dean’s face.
 
The man pulled back, wiping the sperm off of his cheeks and began to spread it
over his pulsing hard-on. Castiel had let out a huge groan, and it was just
turning Dean on more and more. Basking in his afterglow, the angel was
completely spent, sprawled out across the bed. “That wasn’t even the best
part…”
 
Wide blue eyes fell onto Dean, clouded with pleasure. “There’s m-more?” Castiel
asked curiously, in so much bliss that he couldn’t imagine being any happier.
It surely would kill the poor boy.
 
“Yes, there is.” Dean confirmed, spitting on his hands. He stretched out
Castiel’s puckered and untouched hole with one finger. The angel showed no
signs of discomfort, too happy to care about the new and unfamiliar situation.
Castiel trusted Dean. After stretching the hole with one finger, Dean bent
down.
 
His wet tongue now was hell bent on rimming around the other’s anus. Castiel
let out a lot of broken noises as Dean’s tongue whirled in a circle around the
sensitive flesh. Once, his tongue slipped into the hole, causing Cas to groan.
In the back of his mind, Dean had noted that the angel’s little prick was
starting to stick right up again.
 
“I just… just… put it in.” Castiel groaned, not unfamiliar with human bonding
methods. He wanted Dean’s hard erection into him, the teasing being absolutely
unbearable. Even though he was still riding off his orgasm, he found himself
hard and aroused once more.
 
“It’s alright, daddy’s got you.” Dean ensured, barely paying attention to what
he had said until Cas replied.
 
“Okay, daddy.” The angel responded, feeling himself harden upon calling the
human that. Even though there had been many occasions where he had pretended to
be Dean’s son, he had never felt anything until now. It didn’t seem like he was
alone though, the hunter a dark red, his dick painfully hard.
 
Dean decided that he liked being Castiel’s daddy, turned on more and just
wanting to plunge his thick member into the boy’s hole… so that’s what he did.
Even though it wasn’t fully stretched, Dean forced himself into the other’s
body. Instantly the human let out a lot of moans, not used to such tightness
milking and tugging on his cock. Castiel whimpered a tiny bit, not expected the
sudden thrust in… but after he got adjusted, a moan escaped his lips.
“That’s it, baby boy… your pussy is being so good… taking your daddy right in…”
Dean grumbled, so incredibly turned on. He grabbed onto Castiel’s thin hips,
starting to push the boy deeper onto his erection. The angel willingly allowed
it to happen, mouth hanging open.
 
They got stuck in the rhythm of the motion, both overwhelmed by how good it
felt. Dean moaned, not being able to hold it back anymore. He poured his cum
into the angel’s walls, causing Cas to twitch and gasp. Just the feeling of the
warm substance filling him up caused the thirteen-year old to release himself.
 
For a few seconds they just breathed heavily, Dean pulling out and rolling next
to Cas on the bed. The angel curled into the man, enjoying the few seconds of
relaxation. “Can we do that again,  daddy ?”
 
Dean nodded, letting out a deep sigh. “I think we better clean up, and
everything. Sam’s either already waiting outside, or he’s about to be back to
the motel any moment now.” He groaned, not really wanting to do that. Even
though he really just wanted to lay in bed and cuddle with Cas, he knew that he
couldn’t.
 
“Okay.” Castiel agreed, sitting up, kind of surprised by how sore his bum was.
 
***** Daddy's Pissed... And Aroused? *****
Chapter Summary
     Castiel decides to be a little shit and tease Dean in public. When
     they get home, Dean makes sure that Cas gets punished.
Chapter Notes
     Oh boy! This is definitely a tiny bit rushed. School hit me like a
     train and all I want to do is write, but all the other work runs me
     over and leaves me with little energy to create new content. Anyways,
     I got it out, and I'm somewhat alright with posting this!
Arms crossed, brows furrowed, there was no way that Castiel was doing it. While
walking down a main street, Dean had spotted a harp being showcased in the
window of some store. Being cheeky, the older Winchester had pointed it out and
tried to convince the angel to play the harp for them. Sam rolled his eyes
playfully, and Castiel huffed, offended. “I still do not understand why you
assume stereotypical things of an angel. It’s almost as though all the years
we’ve spent together means nothing. I thought I’ve proven to you that I’m
anything but your definition of ‘angel’.”
 
“I don’t know, I mean you’re still pretty heavenly,” Dean whispered to Cas
while Sam had his head turned. Without a doubt, if his younger brother had
heard the comment, he’d never hear the end of it. Castiel rolled his eyes a
tiny bit when he heard Dean’s attempt at flirtation.
 
The three continued to walk down the street until they came across a parked ice
cream truck. Dean’s eyes lit up and he looked over at Sam. “Holy shit, it’s
been years since we saw one of those damn things.”
 
“Yeah.” Sam agreed, seeming to be a little surprised. “I remember the years
where you’d hear the ice-cream truck coming around and you’d always make sure
we got something… whether dad was home or not.” He mumbled, not exactly the
happiest when thinking of his childhood… but the past was in the past.
 
Dean was already getting out money and Cas blinked, looking at the parked
truck. “What does it do?” The angel wondered aloud, not familiar with it. He
wondered why the two humans were so enthusiastic about some old truck selling
frozen cow milk.
 
“Well, I’ll buy you something and you’ll see.” The older Winchester replied,
walking up to the truck. He looked at the selection and got a popsicle. Even
though he was in this thirties, Dean felt as though he was robbed of a
childhood, and this was a little something he could do to try to relive it.
 
“I think I want a popsicle, too, daddy.” Cas said as Sam ordered an ice-cream
sandwich. Dean froze for a second when he heard the angel, looking down at him.
He mentally cursed when he realized that there was a tent forming in his pants.
Even though he wasn’t overly happy about getting an erection in public, Dean
still ordered a popsicle for Castiel. He’d soon realize that was a mistake.
 
Basically immune (or uncaring of) to getting a brainfreeze, Cas took the
popsicle into his mouth the second he got it. The three walked over to a bench
placed on the sidewalk. “This is the good shit.” Dean said again, just so glad
to be having such of an amazing popsicle. Sam nodded, seeming to be enjoying
his ice cream sandwich.
 
Castiel began to suck the tip of the popsicle, not overly impressed with the
frozen snack. “Daddy…” Dean glanced over at the boy, not being prepared for
what he was about to see. The angel was sucking on the tip in a seductive
manner, those damn blue eyes wide. “This is good, but not my favorite
popsicle.”
 
Sam lifted a brow. “What’s your favorite type of popsicle, then?” He asked the
angel, surprised by the statement.
 
The thirteen-year-old happily kicked his feet back and forth. “Cream.” Castiel
replied, causing Dean to turn another shade of red. Out of the corner of his
eye, he noticed the visible indent in his best friend’s pants. Being a little
bit of a tease, he stood up and brushed against the other’s lower regions as he
went to throw out the stick from his popsicle.
 
He couldn’t do anything about it in public, but the second that the two were
alone, Dean knew he had to set things straight. All he could do was think about
fucking that tight hole, and it killed him knowing that he couldn’t just take
the angel right then and there.
 
===============================================================================
 
Dean was sexually frustrated by the time all three had gotten home. He had sent
Sam out on a wild-goose chase for food and a new case. All that the older
Winchester wanted was to spend some time teaching his angel a lesson. At one
point, Castiel was so obedient, but now he was just pushing the limits now that
he knew about the whole world of sex. It was almost as if the angel enjoyed
watching Dean squirm, needing his love… and the man hated it. If anyone was
going to be needing, begging for sex around here, it was going to be Cas.
 
Acting as if he was innocent, Castiel was sitting on the bed. He was reading a
few books on angels, wrinkling his nose in disgust at the lack of accuracy when
Dean grabbed him. It was without any warning, but the man pulled him onto his
lap. “Bend down, Castiel.”
 
Even though he was taken off guard, the boy willingly complied and bend down at
the hip. His behind was exposed to the other as he laid face-down on the
other’s lap. He was in a completely vulnerable pose, but he trusted Dean, and
that’s what was important. Dean would never hurt him, and this was all lustful
play. Dean removed Cas’s pants and underwear so that only his bare behind was
visible. “Do you know what you did earlier?”
 
The angel glanced up at Dean’s chin, unfazed by the situation. “I got you
hard,” Castiel responded, recalling the Winchester’s reaction to his attempt at
seduction.
 
“Which, commonly, is a good thing,  but , you don’t get daddy aroused in public
or else he will fuck you in that very spot.” The human lectured, fingers going
stray and exploring Cas’s backside. “Daddy loves you, but naughty boys must be
punished.” He reminded. With that, he lifted one hand up and spanked Castiel
right on his smooth cheeks.
 
Cas made a tiny surprised noise. “I’m sorry daddy. I want to be a good boy.” He
whispered, bracing himself for the next slap. Dean’s hand hit down on Castiel’s
behind again, watching it turn a soft pink.
 
“That’s it. Be my little angel and beg daddy for forgiveness.” Dean demanded in
a voice that turned Castiel, a strong being, to jelly. He paused for a second,
waiting for a response when he felt something really small poking at his thigh.
Not being naive, the Winchester knew very well that it was Castiel reacting to
what they were doing.
 
“I’m sorry, daddy. Please. Please forgive me.” Castiel whined as his behind was
presented with another slap. “Please fuck me, please. Please. Please.”
 
Content with what he got, Dean smirked. Castiel was back at his mercy, wanting
nothing other than a cock. “What a slut.” He replied, even though he was more
than willing to rip all of the angel’s clothes off of him. His own dick was
pushing against the restraint of his pants.
 
Sitting the angel upright, Dean undid his pants. He threw them lazily to the
ground. “I have work I need to do, so sit right here on my cock until I’m
done.” The Winchester said, not planning on fucking the angel right there. If
Cas made him wait, he was going to do the same to Cas.
 
Letting out a small sound of disappointment, the angel sat himself right down
on the other’s firm erection without any preparation. Cas winced a tiny bit as
he adjusted to the feeling, and Dean grabbed a nearby book. He started to
research the current monster him and Sam were hunting while lazily fucking into
the angel’s clenching ass. Castiel withered on him, doing everything he could
to resist fucking himself on Dean’s prick.
 
Dean just let out a content noise, his hips thrusting deeper into Cas. Then
he’d stop altogether, just enjoying the feeling of Castiel’s inner walls
desperately tightening around him. This was exactly what he had wanted. His
relationship with Castiel now extended into the bedroom, and into cock-warming.
They were already close emotionally but now they were close physically. Dean
had his dick in Cas, and it wasn’t the first time it happened, and it surely
wouldn’t be the last.
End Notes
     Next chapter is subject to featuring Cas being a little naughty tease
     and causing Dean to get hard-in public by calling him "daddy". Later,
     Dean takes care of his naughty boy.
