by Angelsfeartotread
Summary
     Dean and his son Cas have the whole day to themselves and they find
     some fun, and sexy, ways to pass the time together.
Notes
See the end of the work for notes
Cas had his head in Deans lap, gently suckling his daddy's cock as he relaxed,
spreading his sweet little body out across the couch and settling in.
Neither of the pair had any plans for the day, apart from being with the other
which was all they ever really wanted anyway.
They'd had a busy week, lots of deadlines at the garage for Dean and rehearsals
for Cas who had gotten a role in his school play. Dean couldn't be more proud
but it did mean that they hadn't had much time to spend with each other, quick
tumbles before bed certainly not enough. So this Saturday was all about
catching up.
As soon as they'd awoken Dean had been on Cas and then in him, pent up desire
and frustration rushing through the couple causing them to have a very rough
session, Cas flat on his front and Dean forcing himself inside his son as fast
as he could, chasing each other to completion. Then at breakfast Dean had bent
Cas over the table and some interesting things happened with the syrup, and
finally during their shower, Dean gave Cas an awesome blowjob while he fingered
his already gaping, come filled hole and Cas returned the favour; his little
boys mouth stretched around Deans dick never failed to have him coming hard.
Now the loving couple were nude together on the couch, resting while they
recharged after the intense morning they'd had but Cas just couldn't help
himself when his daddy's cock was so close, hence why his lips are gently
pressing against the soft length.
Dean just smiled down at his boy and ran his hand through his matted dark hair,
before trailing it down Cas's smooth, soft skin, and Cas arched his back in
response drawing attention to the delicious swell of his ass where Deans hand
came to rest.
He slowly began massaging the rounded cheek in his hand and he could feel the
vibrations of Cas's pleasured moans along his dick.
He spreads the delectable cheeks slightly, exposing that beautiful
dusty pink hole and began to run his fingers ever so lightly around the
stretched rim. Cas's moans increase in volume as the play continues and he
begins to dip the tip of his finger in and out of his baby slowly, fascinated
by the sight of the stretch to accommodate him. It seemed incredible to him
that his large cock could fit inside such a small opening.
And actually his cock had begun to grow hard again in his boys mouth, unable to
resist the pull of the wet heat or the feel of his finger in his baby. It gave
Dean an idea that he couldn't wait for and he withdrew his fingers whereupon
Cas whined in protest but Dean just picked him up and headed for their bedroom,
and Cas grinned because that meant they weren't stopping. The fun had only just
begun.
Cas wrapped his legs around Deans waist and began to press kisses to Deans skin
and sucking on his neck, all while grinding his tiny, hard cock against his
daddy’s stomach as he attempted to carry him upstairs. But Dean only had so
much willpower and half way up he slammed Cas against the wall and kissed him
ferociously. It was ridiculous how much his son affected him, how much he
turned him on.
His finger made its way to Cas’s hole and pushed inside as his tongue entered
Cas’s mouth in unison. Cas went rigid in his arms before letting out a great
sigh and working his ass backwards on his daddy’s finger.
Dean groaned against Cas’s lips before He pulled back and all put ran up the
rest of the stairs and into their room. If he’d allowed that scene to carry on
any longer, this all would have ended very soon.
He deposited his little son at the end of the large bed and positioned him on
his hands and knees, spread wide so his wrecked hole was on display for his
daddy. Dean got down onto his knees and took a moment to appreciate the sight.
The fucked out hole in front of him was something he was entirely responsible
for and he really liked seeing the evidence of what they’d done together.
When he had admired for long enough and Cas had started moaning softly,
encouraging Dean to hurry up and do something he leant forward and buried his
face in his baby's ass.
He breathed in the clean boy scent that saturated his nostrils and detected a
hint of the strawberry body wash that Cas favoured and that Dean had used to
clean his ass earlier and his dick gave a hearty twitch.
He began by licking along Cas's entire crack, only briefly running his tongue
over his boys hole, before repeating the motion numerous times, getting his
baby's ass nice and wet and drawing some high pitched cries from him.
Only then did he begin running his tongue over the rim, lightly tugging the
loose muscle before easing his tongue inside, at a torturous speed. The taste
of Cas exploded over his tongue and it was almost enough to have him blowing
his load already but he managed to hold off for now.
Instead he fucked his baby boy on his tongue, thrusting the muscle inside with
intent and Cas was writhing backwards on his daddy's face, riding his tongue
like a slut as he screamed out his pleasure.
"Oh...daddy...fuck" amongst many other things, some of which Dean couldn’t even
work out, they were so garbled by the intense feelings rushing through Cas. And
he could tell just how intense it must feel because his babys hole was
fluttering and clenching like crazy around him.
Dean was really glad they didn't have any close neighbours because boy was Cas
loud right now. And he'd hate it if he had to keep him quiet. Nothing got him
to the edge quick like the sound of his son during sex. Especially when he had
something up his greedy ass. Which was in all honestly nearly every day because
Cas couldn't get enough of having his Daddy inside him and it didn’t matter
what way. Fingers, tongue, toys but most importantly cock. Cas wished he could
spend his whole day with his daddy filling him up so beautifully, splitting him
so wide. But Cas contented himself with getting his daddy to fuck him often.
Dean finally withdrew his tongue from his sons ass and gently ran his hands
over his baby's sweaty and flushed skin.
“Do you like that Cas? Do you like having a tongue up your cute ass baby? ”
Cas turned to face Dean and breathed out “yes daddy” in his hoarse voice and
Dean could see the silent tears slipping down Cas’s pretty face from his wide
blue eyes. Though right now the blue was almost impossible to see as his pupils
where blown wide. Cas got like this occasionally when the feelings inside him
became too much and he needs a release. In that case, Dean didn’t want to tease
his baby any longer and his cock really needed some attention now as well.
“On your back sweetheart” he said as he got up and retrieved one of their many
bottles of lube. This time it was a vanilla scented one. Cas was quick to
comply with Deans request as Dean slicked up his cock and fingers before
climbing onto the bed and coming to rest above Cas, his much larger body
dwarfing that of the one below him. He had to supress the shudder of want that
surged through him.
His hand snaked between his baby’s spread legs and he began to apply the lube
liberally around and in his asshole. He didn’t want to hurt Cas if at all
possible and he knew that his son must already be feeling pretty sore from all
of the abuse his ass had taken today but Cas still desired more. And if it was
really bad, he knew Cas would tell him. He’d never do anything his baby didn’t
want.
Once he was satisfied that Cas was wet enough to take him, he positioned his
little sons legs around him and sunk his cock inside his baby’s tight wet heat.
They groaned simultaneously at the sensation of being joined together again in
such a way.
Dean began thrusting his hips, angling just so, so that he was grinding Cas’s
prostate on each inward stroke and Cas was clutching at his Daddy. Dean leant
forwards and gathered his boy up in his arms and held him as he rocked inside
him, kissing him softly wherever his lips could reach. He knew that this wasn't
going to last much longer, if at all.
He moved inside his son a little longer before he felt Cas begin to clench down
on his cock and without much warning he was coming over Deans stomach, exhaling
and whispering daddy softly as he came.
Dean worked him through his orgasm, lightly rolling his hips to keep the
feeling going and then he felt Cas go limp in his arms as he came down. He
thrust a few more times, chasing his own release quickly because it was obvious
how exhausted Cas was and he was coming balls deep in his son in no time, his
come shooting deep inside and marking Cas as his in the most primal way of all.
He carefully withdrew and then pulled Cas in to his body, his broad chest to
Cas’s back and his arms wrapped securely around him, cradling him because Cas
was the most precious and wonderful thing to Dean. Cas fell asleep almost
instantly, once he was comfortable feeling content and loved as he was cocooned
in the safest place he knew.
Dean was quick to follow into slumber, never once letting Cas go.
