****** Not Your Stereotypical Alpha ******
by Oversoul159
Summary
     For the tumblr prompt:
     Could you write about Naruto breeding and impregnating his father
     Minato, fattening him up with several sons? Boruto is their youngest
     and he's got the hots for both his father/brother Naruto and father/
     grandfather Minato so he presents as an alpha at a very young age and
     has a huge cock and rapes Minato, getting him hugely fat and pregnant
     with multiple sons and they have to hide Minato's pregnancy and
     weight gain from Naruto? Minato goes from alpha to omega and is
     embarrassed by being pregnant
Notes
     Hahahahaahah, I almost feel bad for my characters sometimes.
***** Chapter 1 *****
Minato kind of regretted… literally  all  of his life choices.
 
Seventeen and not content with the status quo and stereotypes expected of him,
the alpha had pursued a relationship with his best friend and fellow alpha,
Kushina. And, content in his masculinity, he'd allowed her to take him at every
opportunity.
 
Between the two of them, that added up to… just an unreasonable amount of
fucking, their honeymoon spent with Minato bent over every available surface in
their tiny apartment, crying out as Kushina knotted him for the third, fourth,
eighth time.
 
The best thing about that was that, as alphas, they were virile but basically
infertile and, having been virgins before getting together, that meant they
didn't even need to spend money on birth control or condoms! He got to have all
the joy of being filled near to bursting with his wife's seed and none of the
consequences!
 
Or so they thought.
 
That “basically” qualifier should have been a hint.
 
But it wasn't. It was only six months down the line, far too late to get an
abortion, that the two alphas realized that something might be wrong.
 
There was always an excuse, after all. Bad tacos causing nausea, a new store
nearby causing cravings, too much candy and cum causing weight gain
(technically half true).
 
But pregnancy? In an  alpha ? Yeah, right!
 
Having married and alpha  specifically  to avoid pregnancy, Kushina left.
 
Leaving Minato alone with a baby filling him further each day.
 
----xxxx----
 
A Superior Alpha is an individual born from the union of two alphas. As the
amount of alphas in that individual’s immediate genetic line increase, the
stronger said alpha is in presentation and ability.
 
That was the explanation Minato had been given upon receiving his newborn son
whose limp cock had seemed, to Minato’s untrained eye, to be kind of unusually
large.
 
He had assumed that it just meant that his son would grow up with an extra
large set of family jewels and that would be the end of it.
 
What it  actually  meant was that the boy would grow up with the aforementioned
jewels, fully present as an alpha at the age of  eleven  and then spend his
first rut housebound, drenching every available surface with extra thick semen.
By the third day of said rut, Minato had stopped trying to discipline his
(slightly spoiled) son or clean up the mess, forcing himself to just get
smelling it.
 
And sitting on it. And sleeping on it. And accidentally getting covered in it
if he entered a room without knocking.
 
On the fourth day, Naruto woke him up crying because he just  could not  get
darn cock to go down long enough to even  sleep !
 
And this wasn't… it wasn't really something Minato could have prepared for.
There weren't clinics for this sort of thing, like there were for heat-crazed
omegas. He didn't have anyone that he could turn to (and couldn't imagine
running the risk of letting Naruto out of the house at the moment).
 
So he did the only thing that he  could  do, the only that that could calm an
alpha during their rut:
 
Minato sighed, got off the bed and down on his knees and took his son's cock
down his throat.
 
The boy let out a sharp cry and immediately grabbed ahold of his father's hair,
just shoving and shoving as much of his fat cock down the tight slot as he
could. He threw his head back and moved in closer, trapping his father between
his cock and the bed as he took his pleasure from the man.
 
“Yes! Dad, you feel so  good ! I should have -mhmm- should have been doing this
all week! Why didn’t you  say  I could do this?” The boy rambled as he lay down
on the bed, bending Minato’s head backward in the process.
 
Minato just sighed internally, squeezing his eyes shut as he let his only son
use his throat like a glorified cocksleeve. It had been a while since he’d let
anyone fill his throat like that but he was adjusting quickly, forcibly
swallowing and choking himself on that dick as hard as he could while still
getting some air.
 
Though he was a little rusty, Minato could at least say that he had a  lot  of
experience. More than enough experience to force a baby alpha to cum in three
minutes flat. Though he’d never admit it, Minato had missed the feeling of
being bloated and filled to the brim, of being Kushina’s tight little cum
receptacle.
 
This...was not that. This wasn’t having a nice heavy load dumped into his
stomach as he suckled on the tip of her cock and then cuddling or just taking a
two minute breather while changing positions.
 
This was having his mouth  knotted , his lips forcibly stretched over the veiny
bulb, a wrist-thick cock stuck in his throat as  two gallons  of yogurt-thick
dick cream was pumped into his stomach with a force similar to a firehose.
 
Tears welled up in Minato’s eyes as he tried to pull on his lips to get that
thing out of his mouth. But all he managed to do was grope and massage Naruto’s
knot, earning another short pulse of jizz into his already too-full stomach as
if in warning.
 
Giving up, Minato let his hands fall to the sides, planning to just wait out
that knot.
 
Unfortunately, when Naruto’s knot softened, the kid pulling his still hard cock
out...a problem arose. You see, in order for Naruto to cum as much as he had in
such a short period of time, his cock had to swell, the tip flaring out a bit,
not dissimilar to the way a stallion’s would.
 
Well, more than a bit.
 
Enough that, when Naruto attempted to pull his cock out of his dad’s whorish
throat, the tip got caught in Minato’s throat. And no matter what he did, even
curling over so that he could press down on his dad’s shoulders with his feet
and then try to stand, it stayed stuck.
 
And, well, enclosing one’s cock in a tight wet space and then yanking on it is
pretty much the definition of jacking off, so that went as well as one could
expect.
 
Which was not very well at all.
 
It took less than fifteen minutes more of his son’s brutal facefucking and
another thick gallon of seed for Minato’s body to give up on his. He’d been
filled with so much jizz that his intestines had grown overfilled with it and
he ass simply could not clench hard enough to prevent the goo from shooting
out.
 
It was the only relief he got, his son enjoying his new fucktoy too much to
even notice let alone pull out.
 
So, when Naruto finally softened up to pull of the warm wet fuckslot that he
wished he could just carry around with him, he was honestly surprised to see
the massive puddle of cum beneath them.
 
Instead of inside Minato’s stomach?
 
Curious, Naruto rolled his unconscious and only mildly bloated (for a certain
definition of “mildly”) father over onto his stomach and pulled down his pants.
Only to greet a set of nicely thick asscheeks and a quivering asshole that was
still leaking cum.
 
Unlike his father, Naruto wasn’t really the type of have paid attention in
biology class. So he thought nothing of working his cock back into hardness and
burying it inside of this new hole. A hole was a hole, after all, and his
father had made it clear enough that all of his were available, right?
 
Naruto let out a blissed out sigh when he bottomed out and wasted no time
rutting into his father’s unused passage. And when he felt the weird sensation
of something giving way deep inside of them man, well, Naruto just rejoiced! It
was like fucking two holes at once!
 
Unfortunately for Minato, there was no other hole connected to his womb. There
was nothing to relieve the gallons upon gallons of super-virile baby-making
sperm from attacking his defenseless eggs.
 
And with Minato being unconscious, there was nothing to prevent Naruto’s
instincts from taking over or stopping him from bending over his prone father
and biting into his mating gland, binding them for life. The was nothing to
stop Minato’s body from reacting to the bite, his son’s powerful pheromones,
and  all that cum  and dropping egg after egg after egg for his boy to ruin.
 
----xxxx----
 
Minato woke up on the floor of the living room, his ass gaping and his throat
rubbed so raw from the rough fucking it would probably be days before he could
speak again. He turned his head to find his son sleeping peacefully on the
couch, his soft cock still leaking a tiny bit.
 
It took a couple minutes for Minato to be able to move and several more for the
fact that that his  ass  was sore to catch up to him.
 
He cleaned up as best he could and went down to the nearest pharmacy and bought
several packages of the morning after pill and, just in case, a month's supply
of birth control pills. He knew better than to believe for  one moment  that
there was a chance that he’d be able to convince his son not to fuck him again,
let alone wear a condom.
 
When he got to the cashier, the beta grinned widely at him. “Just got mated,
huh?”
 
When Minato blinked, pretty sure he’d done a decent job of cleaning up, the
cashier rolled her eyes. She pointed to her own neck and then waggled her
eyebrows. Minato’s own eyes grew wide at the realization and he had to force
himself to stay smiling when he nodded.
 
He was bonded to his son! He knew then that while it was the worst day ever,
things couldn’t possibly get any worse.
 
In Minato’s defense,  no one  knew that it was impossible to abort an egg
impregnated by a Superior Alpha’s sperm outside of surgery.
And  no one  knew every egg impregnated by a Superior Alpha’s sperm was
guaranteed to split into twins or triplets.
 
The alpha had no idea that he would be walking home that day already knocked up
with  seven  of Naruto’s kids. Or that he’d stay pregnant. Or that he wasn’t
just  throwing up all that jizz because Naruto had dumped too much inside him
again. Or that he was  craving  instead of just desperate to eat anything that
wasn’t cum.
 
The alpha had no idea that, once again, he’d find out he was knocked up too
late to get an abortion. Or that his son, upon finding out about that attempt,
would fail to realize that it  hadn’t worked  and would tackle him to the
ground and try his very, very  best  to knock the man up again. For  days.
 
The alpha had no idea that the power of his son’s determination was so stupidly
strong that it would actually  work , adding an additional five kids to his
load at nearly five month pregnant.
 
Minato ended up spending over fourteen straight months pregnant. Spent eleven
months just too gravid to do anything but birth and nurse his own grandchildren
as his son used him like a fuck doll, a disability payments the only thing
keeping their bills paid. And all because he hadn’t wanted to be a
stereotypical alpha with a stereotypical omega.
***** Chapter 2 *****
Chapter Notes
     I keep finding mistakes in this stuff. I'm starting to feel like I
     need a beta again.
Minato was grateful for the fact that his son loved him  just  enough to be
willing to settle for only using his throat when they learned that he’d knocked
him up twice at the same time.
 
There were days that Minato spent sitting in their tub, letting the preteen
fill and fill him with cum, his ass hole gapping from the near constant surge
of cum forcing its way out of that end to make way for the gallons Naruto
dumped down his throat.
 
But he survived it. As much as one  could  survive that.
 
Two days after he gave birth to the last of his second litter, Minato called up
Kakashi and begged him to buy the best cervical plug he could find. Once he had
it in hand, he spent half an hour making sure that the plug was in properly,
completely blocking anything from entering his womb and seeding his eggs.
 
And that worked! Minato spent the next six years taking care of his son and his
many, many grandsons, barely able to leave the house, his knot head of a son
needing access to Minato’s tight holes at least seven times a day, lest he go
out and ruin all of the available wombs in the neighborhood (and considering
the amount of damage the boy had done to a barely fertile alpha, Minato  really
didn't want the blond taking his needs out on a beta or, heaven forbid, an
omega ).
 
It was only six years later that a problem arose.
 
You see, Minato had sort of made his peace with the fact that in a couple of
years, he would either need to shell out a couple thousand dollars to hire
prostitutes to handle his grandchildren when they presented along with cervical
plugs for all of them or… or he would have to deal with the horror of being
passed around like a worn out cock sock at a frat house as each children
emptied their balls into him.
 
Minato was obviously saving up money.
 
But one day, when Naruto had taken all of his kids to the amusement park, only
the youngest still home with a cold, something bad happened.
 
“Momma?”
 
Minato glanced up from the dishes he'd been washing and nearly fainted. His
grandson, his barely six year old  baby , was standing before him with a cock
over a foot long that was heavily leaking precum onto the tiled floor.
 
“It won't go down!”
 
Minato blinked hard and shook away the flashbacks that threatened to resurface
at those words.
 
On the one hand, he knew that he had little choice but to help the boy. On the
other hand, Naruto was possessive as hell and would  hate  that. Never mind
running the risk that Boruto would be just as much of a knot head as his
father…
 
But it wasn't like he had much choice.
 
Minato picked up his grandson and went to the bathroom. It would be the easiest
way to hide the evidence. He undressed them both and got into the tub, Minato
sitting and Boruto standing.
 
He jerked the fat cock a couple of times and then took a deep breath before
turning around. He rubbed the tip against his asshole, still slick from
leftover cum that was forever leaking out no matter what he did, and pushed
back on it.
 
He should have known things would end badly. After all, giving a little kid a
cock the same length has his grown father's, without any of the control, well…
 
Minato let out a choked sound as Boruto hammered into him, thrusting every
which way to maximize his pleasure.
 
That first load, just a little larger than one of Naruto’s was enough to knock
the breath out of him. The second even larger load was enough to have him bent
over and sobbing, begging the boy to pull out.
 
He was, of course, ignored.
 
After the third load, Minato was too focused on the pain and on trying to
breathe around the fountain of jizz shooting past his lips that he couldn’t pay
attention to anything else. Boruto, tiny little Boruto, was lying on top of his
mother as he fucked into the man’s firm ass. He was practically resting on
Minato, his only movements being the jerk of his hips and the clench of his
hands as he squeezed his mother’s D-cup tits - the largest ever seen in an
alpha male.
 
So when he felt a weird pressure against his dick, rather than attempting a
different angle, Boruto just lifted himself off of his mother and then dropped
his weight down. This hole may have once belonged to his dad, but now Boruto
felt entitled to do whatever he wanted with it! So he pushed and pushed past
that pressure until it gave way and he could once again bottom out in Minato’s
ass.
 
Boruto moaned deeply at the sensation of something just  clutching  at the head
of his cock, squeezing and pulling at it like it never wanted to let go. The
feeling was clearly mutual.
 
Minato’s cervix, still so nice and (relatively) tight from half a decade of
disuse, clamped right down on Boruto’s cock, preventing the boy from pulling
out even if he wanted to. Leaving the barely there Minato no choice but to take
those fourth and fifth deposits right into his womb.
 
Some four hours later, once Boruto had softened up and fallen asleep, Minato
woke to find that most of the cum had already flown out of him on its own. So
he got up slowly and cleaned them both up, doing his best to get everything
back to normal in preparation for Naruto’s arrival.
 
And it worked! He was none the wiser!
 
He had no idea that a twice-superior alpha had dumped more than his share of
seed in his womb. He had no idea that his cervical plug, which had seemingly
fallen right back into place, was dislodged just enough to keep some of
Boruto’s cum in his womb while  also  allowing a cups worth of Naruto’s cum to
slip in here and there every time the teenager fucked him.
 
Or that he’d have to contend with Boruto mounting him every time he got down on
his hands and knees to clean the floor (always managing to trap Minato when
Naruto wasn’t home), his pert ass constantly on display since Naruto only let
him wear skirts and thongs to allow for easy access.
 
Minato had no idea that it was possible for an alpha’s body to decide to change
itself into a highly fertile “superior omega”, a leftover evolutionary trait to
aid repopulation in times when omegas were scarce.
 
----xxxx----
 
Minato bit his lip hard as he watched the doctor set up the ultrasound. It was
a different doctor from he’d used nearly seven years ago during his previous
pregnancy. One unaware that he was once an alpha (and that he still believed
himself to be one). He closed his eyes and resisted the urge to rub his swollen
stomach. In the last three months he had swollen up as much as he had seven
months into a normal pregnancy. He figured that Naruto had managed to  somehow
knock him up before Boruto had even presented and just prayed that he wasn’t in
for another double pregnancy.
 
Because he eyes were closed, he didn’t notice the way the doctor’s eyes grew
wide as he stared at the screen or the way he glared at Minato in disgust the
moment he took his eyes off it. It was really just  too much  and he couldn’t
take it any more!
 
Here he was, an alpha doctor with an  infertile  beta wife, unable to have
children, while whores like the one in front of him flitted around spreading
their legs for  everyone , popping out children left and right!

 It just wasn’t fair!
 
The doctor stood silently and dropped his pants, revealing a cock that grew to
nine inches as he stroked it into hardness. He grabbed Minato by the chin,
startling the former alpha into opening his eyes and his mouth. That hard cock
was shoved straight down his throat, despite Minato’s flailing. He tried to
pull away, but the doctor had a firm grip on his head and jerking his head up
and down on his cock so hard, Minato was sure he would end up with bruises on
his lips and nose.
 
“Such a fucking  dumb  little omega! What the fuck is wrong with you, huh?! Did
you overdose on fertility pills at a party so hard you couldn’t stop everyone
and their cousin from knotting your ass? Or is you alpha pimping you out
because they’ve realized that all you’re good for popping out babies and
milking dick? Nineteen fucking pups! Never in my life have I met an omega so
fucking irresponsible as to let an alpha dick ‘em up that hard!”
 
Minato couldn’t even pay attention to the rest of the doctor’s long,  long
diatribe. He was stuck on the word nineteen.  Nineteen . That was why he was
already so big. Between the two of them, those boys had wrecked so many of his
eggs. And as the doctor stuffed his thick knot past Minato’s lips, he realized
that the man was probably right. There was no coming back from nineteen. No
doctor would even consider giving an abortion to the kind of complete and total
cum dumpster that could get themselves knocked up with nineteen pups at the
same time. And that was assuming that his boys didn’t add to the load.
 
Minato clutched his stomach and cried. He knew now that it wouldn’t be long
until he was completely bedridden, until he was so massive with his own
grandchildren  and  great-grandchildren that he completely filled his bed. He
knew that there would be nothing to stop Naruto, Boruto or any of the other
twice-superior alphas from accidentally turning him into a baby making factory.
Nothing to stop them from climbing into his bed in the middle of the night and
using him like a glorified fleshlight. Nothing to stop them from stretching his
ass out into worthlessness by stuffing two, three, cocks into him at a time.
 
Nothing to keep Naruto from leaving him as the cum dump to their brood and
knocking up another omega or ten.
 
As he left the doctor’s office, with a clean bill of health and a belly full of
jizz, Minato sighed and forced himself to find something resembling peace with
what his life would be from now on.
 
And then he noticed a young woman, not much younger than Naruto, standing at a
busstop. She was clutching a suitcase in one hand and rubbing a sniffling nose
with the other. Just looking at her, it was obvious that the girl, with long
black hair and a set of E-cup tits, was a  very  fertile omega.
 
Minato made his way over to the girl and offered her a sympathetic smile that
she returned shyly.
 
Misery loves company, after all. And Minato had the feeling that he would need
a  lot  of it.
