Summary
     RJ and Ollie are turning 10, so they finally get to play with their
     daddies like Dustin does. Also, Stiles gives in to a dangerous vice.
Notes
     So this is part three, and boy is it sO MUCH. LIKE SERIOUSLY ITS WAY
     MORE FUCKED UP THAN THE FIRST ONE. We got mpreg and underage sons and
     incest everywhere so if you're not into those things run along
     because here's the deal:
     Dustin is the son of Sheriff Stilinski and Stiles
     RJ and Ollie are twin sons of Scott and Stiles
     all six are gonna end up fucking a lot in a bed, and someone may end
     up pregnant. I havent decided who yet, so we're gonna take a vote at
     the bottom notes.
     If you want a big family orgy with kids getting taught by their dads
     all about sex through a hands-on approach, welcome.
See the end of the work for more notes
“Are you sure it’s okay?”  Scott was nervous about their plans for the
following day, but Stiles just kissed his husband gently on the lips and
smiled.
“It’ll be fine.  Anyways, they’re too excited now, we can’t just suddenly not
do it—especially since we did it for Dustin on his 10th birthday, and nothing
bad happened.
“Stiles didn’t show signs of being fertile until he was nearly twenty,” John
reminded his more nervous lover, “And they’re all Stiles’ sons.  If any of them
has the gene, they probably won’t show for another few years, and we can get
them on the pill when they’re thirteen anyways, if you’re worried about getting
one of them pregnant.”
Scott blushed.  “It might be okay someday, but for right now they’re so young. 
We should just be careful, is all.”
“We are.”  Stiles assured.  “Now go to sleep.  You remember how busy Dustin’s
birthday was, and now we have two little boys to please.”
===============================================================================
Their day started the same as any other.  Scott got up early to make breakfast
while Stiles and John spent some alone time together.  But when Scott went up
to the twins’ room to wake them up for breakfast, he was treated to the sight
of his young sons completely naked and 69ing each other.
“Boys.”  Scott laughed, “I know you’re old enough now, but Daddy, Papa, and I
have a surprise for you after breakfast.  Don’t play around too much.”
Dustin popped up behind him, also fully nude.  The Stilinski household made the
rule that if you’re over ten, you can spend as long as you want naked—a rule
Scott, Stiles, and John often exploited themselves.  Even now, Scott was naked
as he stood amongst his children.
“I get to play during the surprise too, right Dad?”  Dustin asked, grinning up
at Scott. Scott ruffled Dustin’s hair and nodded.  “You’re a big boy already,
so you get to help us show RJ and Ollie what it’s like.”
Dustin beamed, and ran off down the hall to eat.
“Don’t take too long, I don’t want your food getting cold.”  Scott warned, but
he still looked happy, “And Happy birthday, boys.”
===============================================================================
 Once RJ and Ollie finished playing with each other and finished their
breakfasts, they ran back upstairs to their fathers’ room.  Scott, Stiles, and
John had decided to remove the door to their bedroom once the twins had turned
8 and Dustin was 9, believing that exposure to sex early was useful and natural
for a family like theirs, but they were told they could only watch from the
doorway until they were 10, when they’d be old enough to join in when their
parents played if they wanted to.
Dustin had never been so happy to be a year older than his brothers.
But now RJ and Ollie were 10 years old, which meant they could join in.  When
they reached the entrance to their parents’ bedroom they stopped out of habit. 
Inside, the “festivities” were well under way. Scott lay on one side of the bed
with Dustin in his lap, playfully kissing the boy who was solidly filled with
his cock.  That was one of Dustin’s favorite things, to be filled and kissed
and loved, not even necessarily fucked (although he totally loved that too).
Next to Scott was John with Stiles on his lap, Stiles facing away from his
father towards the doorway as he slowly rode the cock that made him and helped
make his oldest son.
“Hey, kids.”  Stiles greeted, breathless, “You don’t have to wait outside
anymore.  Come in.”
That was all the invitation they needed, and with excited laughter the twins
ran into the room and clambered onto the bed.  “Did you prepare yourself like
Papa said?”  asked Stiles, and both boys nodded.  They turned so their asses
faced their Daddy Stiles, showing off the base of the plugs they’d used to
stretch themselves open in anticipation for getting the real thing from their
fathers.  Stiles gently tugged on each one, testing how tightly they fit inside
his virgin sons.  “Good boys.  Take them out now.”
RJ and Ollie obeyed, their giggles turning to high moans as they pulled the
plugs from their asses.
“Okay, honey.”  Scott spoke to Dustin, gently pulling the boy off of his cock. 
“It’s your brothers’ turn now.”
Dustin pouted, but shifted to the far end of the bed, giving RJ and Ollie
room.  “One of you gets Dad’s cock, the other gets Daddy’s.”  Scott explained. 
The twins glanced at each other, then RJ went for Stiles and Ollie moved onto
Scott’s lap with rehearsed precision, like they’d discussed it before this
moment.  With the stretch from the plugs they’d worn, it was easy for Ollie to
take his father’s cock in his hand and sit down on it, his own little cock
harder than it had ever been as he finally got to play with his Dad.   Scott
smiled and began to kiss his son deeply, rocking gently and slowly, not wanting
to overload his now non-virgin son.
RJ was just as eager as he sat down on Stiles’ cock, wrapping his arms around
his Daddy and burying his face in his chest.  Stiles was still riding John’s
cock gently, the motion now pushing him in and out of one of his younger sons. 
He kissed RJ fully, opening the boy’s mouth to his tongue and fully enveloping
him in the world of sex he had seen but been forbidden to enter until this
point.
That’s when Dustin finally spoke up.  “Hey!”  He whined, “Where do I go?”
Stiles responded by gently turning RJ around on his cock so that the boy was on
his hands and knees on the mattress.  “You can use RJ’s mouth, honey.”  RJ lit
up and nodded, opening wide, and Dustin grinned, shuffling over to his brother
and pushing his cock between his lips.
“You’re really good at this RJ!”  Dustin laughed, bucking like a jackrabbit
into RJ’s mouth, which RJ took with ease.  Secretly, RJ and Ollie had been
practicing with each other’s mouths on each other, even though Dad Scott and
Papa John had said not to until they were older.
They fucked all day, the entire family of six, in every imaginable
combination.  Dustin got a chance to get fucked by Papa John while Dad Scott
and Daddy Stiles helped RJ and Ollie fuck each other.  Stiles spent nearly an
hour getting penetrated by Scott and John at the same time, while next to them
Dustin bounced happily on both of his twin younger brothers’ smaller cocks as
they kissed each other hungrily over their older brother’s shoulder.  They took
a break for lunch but spent more time kissing than eating, each father hungrily
wrestling tongues with the son on their lap.  John fucked Stiles’ throat to
teach their sons about deep-throating, and after Ollie and Dustin both face-
fucked RJ, Scott slid his considerably larger cock into the younger boy’s mouth
and watched as he filled his throat, confirming that their little boy in fact
did not have a gag reflex.
And they came.  God, did they cum.  Stiles and Scott shot jizz over both twin’s
faces until they were laughing from how much it dripped from their chins, and
Dustin rutted into any hole he could find, leaving small loads in each of his
fathers’ asses as well as both of his brothers.  Scott hungrily swallowed down
the sweet liquid that shot from RJ’s cock—his first ejaculation ever—and Stiles
did the same with Ollie but turned over his shoulder to kiss it into John’s
mouth while riding his cock again.
They finally wrapped up shortly after dinner by fucking in a line, John at one
end with his cock inside Stiles, fucking him into Scott who was buried inside
Dustin and forcing his son’s cock deeper into Ollie’s asshole, while Ollie
fucked his twin who was sprawled on the mattress.  By the end they were all
sticky, sore, and sated, and Ollie and RJ had fallen asleep even with cocks in
their holes, so Scott climbed out of the mess of limbs and carried them both
back to their bedrooms, tucking them in.  Shortly after, Dustin went off to bed
too, and the three fathers exhaled a sigh of relief together.
“You were right.”  Scott said, “Everything will be fine.”
“Yeah, it will.”  Stiles replied.
===============================================================================
It was past midnight when Dustin heard his door open, but he knew what was
coming.  He hadn’t bothered to put on pajamas—he hadn’t worn clothes at home
since his 10th birthday—and he’d used his own plug to keep himself open for
what he knew would come when the rest of his family was asleep.
“Hi Daddy.”  Dustin said with a grin, wiggling out from under the sheets. 
Stiles didn’t say anything.   He never did when he snuck into Dustin’s room. 
He just pushed his oldest son down, sunk his cock into the boy’s ass, and
kissed him like the world was going to end as he pounded away.  Stiles had seen
himself in Dustin, the young version of himself so in love with his father but
not knowing how to pursue it.  It took ten years of longing for Stiles before
he got to have sex with John.  He wouldn’t make Dustin go through the same
thing.  They kissed so deeply Dustin felt breathless through the small moans
that Stiles swallowed up like shots, and they seemed to have the same
inebriating effect on him.   As Dustin curled into Stiles, his Daddy’s thrusts
grew erratic, and Dustin knew he would soon be filled with his Daddy’s cum,
just like his Daddy wanted.
They came in unison.
“You’ll love it, just like I did.”  Stiles mumbled against his eldest son’s
lips.  “The moment your body is ready, I’m gonna pump you full so you can carry
a baby just like I did.  I know you can.  You’re so much like me, baby.”
Dustin came hard, in spite of how many loads he’d shot earlier in the day. 
Normally his Daddy would lick it up, push the plug back into Dustin’s ass, and
leave—but today he did something different.  He scooped Dustin’s thin load off
of his stomach and pushed the white fluid into his ass, fingering himself full
of his son’s cum with his cock still pushed deep inside his little boy.  “God,
I need to feel it again.”  Stiles moaned.
Tonight his Daddy left his cock inside of him, and put the plug in his own ass,
then curled up next to him in bed and fell asleep, their bodies still locked
together like perfect puzzle pieces.
 
End Notes
     SO HERE'S THE PART WHERE I NEED YOUR HELP. I haven't decided what I
     want the next step in this series to be, and I don't really know what
     people want. The way I see it, here are the following options to
     choose from:
     1) Dustin ends up impregnated by Stiles.
     2) Stiles ends up impregnating himself from fingering Dustin's cum
     into his ass.
     3) Both Stiles and Dustin have been knocked up by each other.
     4) Neither Stiles nor Dustin ends up pregnant.
     5) PICK A PAIR OR A FEW PAIRS AND LETS MAKE BABIES. Think Ollie
     should be having Scott's baby? Cool! Think RJ should be pregant with
     Dustin's Kid? Great! Think Scott should be pregnant with RJ's baby?
     That works too! The only character who isn't fair game to be pregnant
     or impregnate is the Sheriff, since it's been established in the fic
     canon that he's too old. But any combo of RJ/Dustin/Ollie/Stiles is
     up for potential new Stilinskis - meaning their can be up to four
     pregnancies if we really wanna go wild, or as little as none if im
     going way to far with this inbreeding thing.
     But inbreeding isn't a common fic theme and somebody's got to do it,
     so why not me?
