****** the plan of a lifetime ******
by LilMysterios
Summary
     Because Mary died too young, John never had the chance to have the
     big, happy family they always wanted together. But now that Dean has
     presented as an omega, the solution to this problem is obvious...
     (Or, the one where John is obsessed with getting Dean pregnant.)
Notes
     As always, everything is in the tags and warnings. Please read
     everything carefully before starting this fic. ^^
     I still work without a beta, so if there are any mistakes, there are
     entirely mine... and I would appreciate if you told me where they
     are. You know. So I can fix them.
     Anyway, enjoy!

It was his right.
It was his right and he was gonna make the most of it, damn it! Hewas the alpha
of the house, and he made the decisions, and he didn't want to hear what anyone
had to say about it, especially his own kids.
It didn't matter how hard Dean fought before John pushed his little pants down,
or how loud he begged when John roughly prepped him, or how sweetly he sobbed
when John slid inside him... John wasn't gonna stop taking what was fucking
his.
And so despite the tears, despite the sobs, he always ended up pinning Dean
down, ignoring the boy's attempts at bucking him off -- as if that was gonna do
anything -- and keeping one big hand flat against the boy's upper back to press
him down against the mattress, nice and presented with his tight little bum in
the air, all pale and smooth and begging to be ruined... and then John would
open him, quick and efficient, stretching open his sweet little hole with rough
fingers.
And yes, Dean would protest, he would sob and whine pitifully, fat tears
staining the sheets under him, but John didn't mind; sure, he would have liked
Dean to be a little more cooperative, maybe even a bit grateful that his father
was granting him the honor of being his new bitch, but he'd never minded using
a bit of strength to get what he wanted... and Dean could cry all he wanted,
his tiny little omega body was no match for his father's big, muscled alpha
form.
Plus, Dean could say what he wanted, protest with all his heart, but every time
John finally got his fingers stuffed deep in his son's fresh little cunt, his
whole hand would be covered in slick in no time... so, yeah. John knew better
than to think his little baby whore of a son didn't want his knot.
In fact, Dean's complaints would always quiet down when he got his dad's cock
in him, pained hiccups going tinier and tinier as the huge, fat member pushed
through his soft, young insides, and John would enjoy the newfound silence and
watch with incredible pride the way his son's pussy would stretch and flutter
wide around him...
The reason, that made it John’s right to take advantage of his son in this
manner? Dean was an omega. Like his mother, bless her soul, he was John's to
claim and to breed, and John was only doing what he had to do.
He and Mary had had a plan, you see. They'd wanted a big, happy family, lots of
kids running and tumbling around and filling the house with laughter... 
But now that Mary wasn't here to see the plan through, it was John's duty to
make sure their future planned together would happen, even with her gone to a
better place. After all, how fortunate was it that Dean had turned out to be an
omega? John would have been perfectly okay to go find a new wife to carry his
and Mary's kids, but he never even had to look elsewhere! For suddenly Dean was
in heat, soaked in slick and spreading shakily his soft, slim thighs, body
arched on his childhood bed, revealing himself to be the perfect answer to
John's prayers: a pretty little thing, sweet and ripe and ready to be filled
with come and bred full of kids right away.
John hadn’t hesitated, of course. He’d dropped his pants right then and there,
and his cock was barely out of them that he was already deep inside his son’s
creamy little cunt, groaning at the delicious clutch of a tight, virgin omega
hole.
And as he took his eldest son’s virginity, fucking mercilessly the supple body
through his first heat, John couldn't believe his luck. Because even more than
the fact it would make everything so much more convenient(seriously, how much
time would he gain by having a bitch at home, all his and ready to be fucked
every single day? It beat going out there to find a willing womb, for sure), it
also meant that his son would actually get to help him with his project, that
he was gonna take part in it… and John knew, deep in his heart, that they would
all be even closer after that; one big, perfect family.
So, yeah. Dean, an omega? That was a sign if John had ever seen one, and if
someone up there thought he was doing the right thing, well, he wasn't about to
turn his back on fate's favors.

"Yeah that's good, baby," he was saying. "Take it deep, feel it stretch your
pretty little pussy."
John's cock looked grotesquely enormous like this, sliding in and out of his
son's pink, over-stretched cunt, the wrinkled skin pulled tight around the
thick shaft, and yet he had never seen anything this profoundly satisfying.
"You’re such a good bitch for me, such a good little hole... see how your
body's opening for me, hungry for my cock..."
Dean cried out when John flicked one of his nipples.
"You're gonna look so good all bred up, Dean..." John sighed, and thinking
about that almost made him come. "With your pretty little titties swelling with
milk and your fat belly growing bigger and bigger everyday..."
He rolled the pretty pink nub between his fingers, watching the sensitive flesh
peak and redden.
"Maybe I'll let Sammy suck you, would you like that?" he asked, voice gruff.
"Having your baby brother sucking on those pretty little tits, milking you
dry?"
Dean whined, high and confused, and John chuckled, leaning down to lick a wet
stripe across the wet, plump tit.
"Yeah I bet you'd love it, having his tongue on your nipples, drinking from
you… it was one of your mother's favorite things."
He bit down sharply and suckled the small mount of flesh in his mouth, rolling
his tongue around it and sucking hard on it, making Dean buck and cry out.
"Don't worry, though," John managed to say around his mouthful. "I'll still
fuck you while you carry our child into this world... wouldn't want him to feel
unloved, right? We've gotta make sure he knows just how much he was wanted..."
John let go of Dean’s abused tit, admiring for a second the raw, swollen flesh
before pulling Dean closer to him, slamming that tight little omega ass on his
lap… Dean mewled at the added pressure, squirming as his dad’s cock stuffed him
even fuller, but John ignored him and started to go faster, lifting his son
effortlessly and picking up the rhythm until Dean was all but bouncing on his
cock, tiny supple body shaken mercilessly from where he was impaled on his
father's dick.
"You're so good, Dean -- so good to me..." John groaned, breath shortened as
his orgasm built in his gut. "Such a sweet little bitch."
He gave one last thrust, so hard it made Dean howl in pain, and nosed at Dean's
neck, inhaling the ripe scent, the sweetness of his pretty omega whore.
"Your mother would be so proud," he rasped, and he came like a fucking freight
train, emptying himself inside the boy's soft, creamy cunt.
He stayed inside Dean for as long as he could, feeling his cock pulse hot and
thick through the aftershocks of his orgasm, and when he pulled out he couldn't
help the groan of satisfaction at seeing his son's hole like this, like it was
always supposed to be; a sloppy, puffy mess, overflowing with alpha seed,
wrecked and oh-so-beautiful.
Dean was apparently too fucked-out to move, and John tutted at the come that
was already oozing out.
"Well look at that, baby," he chuckled. "I fucked you so good you're leaking
everywhere!"
He grabbed the shiny butt plug sitting on the bedside table and worked it
slowly inside Dean's twitching, gaping cunt, ignoring the omega's weak jerks as
his father’s come was carefully pushed back inside of him.
"That's better," he said when he was done, leaning back to admire the way the
plug was now settled, snugly trapped between Dean's firm ass cheeks. "We have
to keep all that good come inside if we want to succeed! Plant some strong
little pups in you while you’re ripe for it."
Dean only whined feebly, not even able to move as John stood up.
"Don't go anywhere," he ordered on his way to the shower, his palm hitting
Dean's pert ass cheek in a teasing, possessive slap. "There's only two days
left of you ovulating, and we've got to make the most of it."
After all, there was no time to lose. 
End Notes
     As usual, I have no idea if I'll write another part of this,
     inspiration could strike at any moment! So if you'd be interested in
     reading a hypothetical second chapter (a nice commenter suggested
     omega!Sam, that's something I could get behind), just subscribe to
     the fic, I guess. ;)
