See the end of the work for more notes
Dean and Cas have been together for a few weeks by now. They’re still getting
comfortable around each other even though Castiel can be a little shy and Dean
can be a little hesitant to push Cas where he doesn’t want to go. They know a
lot about each other by now, they know that the relationship isn’t just about
sex. It’s nice really. But they still haven’t gotten to where they both want to
be quite yet. Dean’s dick pounding into Cas.
Cas is a virgin and he has to admit that though he’s fantasized about Dean
fucking him until he can barely walk like a lot, he’s still a little nervous.
But by now, after being with Dean for a few weeks, he knows that Dean is
gentle, that Dean won’t hurt him. Dean will only be rough with him if Cas wants
him to be rough with him, like when Cas asks Dean to pull on his hair whilst
he’s blowing Dean. So, one day after school when Dean has just sucked Cas off
because Dean insisted because Cas is usually the one on his knees, not Dean,
Cas brings it up. They know that they don’t have a lot of time since Cas still
has to get home, but still, Dean is sitting in his chair behind his desk and
Cas is in his lap, lazy kisses being traded back and forth. Cas finally pulls
away with a sigh. Dean nuzzles him a little, knowing by now when Cas is feeling
uncomfortable.
“What’s wrong?” Dean murmurs, and Castiel squirms a little in his lap. He sighs
once more before pulling back so that he can look Dean in the eye.
“I want you to fuck me. I want you to take my virginity,” Castiel tells Dean
surely. Dean was sure that his heart had stopped. He blinks, staring back at
Cas.
“Uh,” is all that Dean manages because, Christ he’s wanted Cas’ ass ever since
he first saw him in class and Cas shot him a shy little smile. Cas shifts a
little bit more in his lap, letting his arms hang lazily over Dean’s shoulders.
“It’s just, we’ve been together for a little while now, enough for me to get to
know you. And I really like you, y’know, a lot. And, um, I’ve really wanted to
do this, for you to, y’know, fuck me, ever since I first saw you. And now that
I know you and everything, I really want you to be the one to take my
virginity. I really like you, Dean, and more importantly, I trust you. So, if
you’re okay with it and you want it just as much as I do, I figured that we
could find a way for this to happen,” Castiel explains so softly and shyly that
even though Dean came like just ten minutes ago, he’s sure he’s gonna pop a
boner.
Cas is blushing furiously, looking down at Dean’s lap and shifting, glancing up
at Dean every so often. Dean finally blinks once more, gathering his words and
getting himself together because, okay, this is a serious discussion and he
can’t just hop in and tell Cas that he will definitely fuck him at the very
next chance that they get.
“Cas, are you sure? I mean, I don’t want you to feel pressured or anything, we
can keep doing what we’re doing for as long as you want,” Dean reassures.
Castiel smiles softly and shakes his head.
“I wanna take it further as long as you do too. I’ve wanted this for awhile,
Dean. Sure, I’m a little nervous, but it doesn’t take away from the fact that I
know and trust you. I know that you’ll make it good,” Castiel continues. Dean
smiles softly and runs a hand through Castiel’s hair.
“As long as you’re sure.”
“I can assure you that I am.”
“When do you want to do it?” Dean inquires. “And where? Do you have any ideas?”
Dean goes on. Castiel grins a little and nods.
“I figured that maybe on Thursday you could come over to my house and pretend
you’re my tutor. I can tell my parents that I’ll be out late so that we can do
it after night falls. Maybe, if you’re okay with it, you could drive me out to
a really secluded place that no one knows. Then we could do it in your car. But
only if you’re okay with it,” Castiel goes on, and Dean grins, pulling Cas in
for a chaste kiss.
“You’re a genius.”
                                      ---
Thursday rolls around and Dean and Cas have agreed on a time for Dean to come
pick Cas up. When Dean’s car shows up in the driveway Cas gives his parents a
whole fake spiel about how he’s going to be out a little late with his tutor.
Cas manages to convince them with minimal questions and before Cas or Dean know
it they’re in the middle of nowhere just after dusk.
Dean and Cas sit there in silence for a bit, just looking around. Dean can tell
that Cas is nervous so he reaches a hand out to find Cas’. Cas looks over at
him with those wide innocent eyes that Dean can catch in the fading light of
daytime.
“We can take this as slow as you want, Cas, really. If you wanna just sit her
for a while then that’s fine. I’m not gonna push you and I’m not gonna hurt
you, you know that right?” Dean soothes, and Castiel smiles softly and nods.
There’s a pause before Cas shifts, getting up to crawl onto Dean’s lap. Dean
easily welcomes him, resting his hands softly on Cas’ waist. Castiel looks him
in the eye, his thighs straddling Dean, his arms resting on Dean’s shoulders.
He leans forwards for a sweet, chaste kiss.
“I trust you, Dean,” Castiel murmurs. Dean kisses him once more.
“I trust you too, Cas,” Dean mutters back. There's a moment where they stay
there, breath ghosting each other’s lips, everything around them quiet, no
rush, just a sweet silence that’s savored. But, soon enough, Cas is pressing
forwards, pressing his lips to Dean's. Dean waits and lets Cas deepen the kiss,
their tongues sliding together hot and wanting.
Cas sighs into the kiss, the feeling of Dean against him grounding him,
relaxing him. Dean runs his hands soothingly down Cas’ sides until he's
gripping Cas’ ass and bringing him closer, their crotches aligning. Dean lets
out a soft moan as he feels the heat of Cas’ body run through him, their chests
pressed together.
The kiss grows sloppy, eagerness bleeding into it. Cas finally pulls away to
catch his breath and Dean takes the opportunity to move his lips down Cas’
neck, nipping and kissing, mouthing hotly, careful to not leave any marks. Cas
moans softly, loving the feeling of Dean's stubble scratching against the
sensitive skin.
Cas can already feel himself growing hard, and he squirms a little in Dean's
lap, grinding his hips down to find that Dean is too. Cas bites his lip at the
friction, his eyelids fluttering shut as he grinds his hips down in sweet
little circles that drive Dean crazy.
Dean brings his lips back up to find Cas’, enveloping them in another messy
kiss. He slides his hands up Cas’ shirt, feeling the hot skin there. Cas gets
the silent message and pulls away from the kiss to tug off his shirt. Dean lets
out a soft noise of satisfaction at the sight of Cas, who he had never seen
without a shirt.
“God, Cas, you're so fucking beautiful,” Dean murmurs, and Cas blushes a
little, grinning as he presses forwards for another kiss.
Dean lets his hands roam Cas’ skin, every inch that he can reach. Cas finally
pulls away, his hair already ruffled, his cheeks pink and his eyes wide with
lust. “Can we, um, go further?” he questions shyly. Dean smiles and kisses his
cheek.
“You wanna get in the backseat?” Dean inquires, and Castiel nods eagerly.
“Alright, you get back there, I just have to grab something,” Dean tells him,
and Cas climbs off of his lap, climbing into the backseat. Dean immediately
pulls off his own shirt, then awkwardly kicks off his own jeans and boxers
until he's fully naked. He reaches into the glove compartment, grabbing a
bottle of lube before climbing into the backseat where Cas is spread out and
waiting and God, Dean couldn't have asked for more.
Cas lets his eyes rove Dean's body, Dean's body that he's never seen fully
naked before. The sight makes his mouth water.
“You wanna get these off?” Dean asks kindly, gesturing to Cas, jeans. Cas nods,
unbuttoning and undoing the zipper on them before awkwardly pulling them off
with a little help from Dean, who tosses them aside.
Dean lets out a soft groan at the sight of Cas. He's never seen Cas fully naked
before either and the sight is making arousal burn hot through him.
Cas catches that Dean doesn't have a condom and he looks up at Dean. “Are you
clean?” Cas questions because obviously Cas is a virgin but Dean isn't. Dean
nods, however.
“Don't worry, I just got tested,” Dean assures him, and Castiel relaxes. He
trusts Dean. “I'm gonna take good care of you, okay?” Dean reassures Cas, who
smiles softly and nods. Dean rests one hand on Cas’ shin. “You wanna lift these
to your chest for me?” Dean asks, and Cas nods, shifting a bit and pulling his
legs up to his chest. Dean licks his lips and shuffles forwards, popping open
the cap to the lube. But then an idea hits him.
Cas watches, furrowing his brow as Dean lowers his head between Cas’ thighs.
Cas isn't really thinking so he's not quite sure what to expect but then when
Dean's tongue meets his rim, he fully understands.
At first Cas tenses, letting out a surprised little squeak, but then he slowly
relaxes, letting out a long, low moan. He realizes that Dean is just trying to
relax him before he actually gets his fingers inside of him. So, Cas just melts
into it, letting Dean do his thing.
Cas has dreamed of this before, wondered what it would feel like to have
someone rim him, but he never quite expected it to feel so good. Dean's tongue
is skilled, he definitely knows what he's doing. The feeling of something hot
and wet maneuvering such a sensitive area is bliss.
Eventually, Dean pulls away, earning a little whine from Cas. But,Cas easily
takes back that whine when he feels Dean's finger slide slowly into him. Cas
lets out a soft moan at the feeling. Another thing he's imagined are Dean's
fingers, how thick and perfect they would be. Sure enough, they’re better than
imagined.
Dean thrusts his finger in and out and Castiel relishes the slight stretch. He
watches Dean's head pop up from where it was and he watches as Dean begins to
kiss up and down Cas’ thighs. Cas smiles and bites his lip, feeling that same
stubble brushing his skin, watching as Dean begins to suck bruises into it.
Both of them know that they can't leave marks on each other's neck, so Dean is
thankful for the opportunity to make a mark of possession somewhere where only
Cas will see.
A second finger joins the first and Cas lets out a soft moan. He brings a hand
up to card through Dean's hair, tilting his head back and simply feeling. He
waits patiently for Dean to find his prostate, and when he does, his grip on
Dean's hair tightens and he lets out a little moan. Dean smiles, passing the
bundle of nerves with every thrust of his fingers.
A third one is soon added and Cas is panting, anticipation running rampant
through his veins. He's still a little nervous but at this point he's mostly
excited. He's thought about this more than a lot, and he knows that Dean has a
nice cock, a thick cock, and Cas can bet anything that it will feel a million
times better than his own fingers, than Dean's fingers.
When Dean pulls out his fingers Cas’ breath hitches. His heart is beating
faster than it has in a long time, and his whole body is tingling. He watches
Dean shuffle forwards, coating his cock in a generous layer of lube. He moves
forwards even more, bracketing his arms by Cas’ sides. Cas pauses before
wrapping his legs around Dean's shoulders, hooking his ankles behind his head.
He can feel the head of Dean's cock nudging his entrance, and the feeling makes
his breath hitch once more.
“You ready?” Dean asks so softly and kindly that Cas just wants to melt. Cas
takes a breath and nods, shutting his eyes because he wants to feel every inch
of Dean when he slides in.
Dean pushes in ever so slowly, enough to get Cas to hold his breath. Cas feels
him and he isn't aware of the fact that he lets out one long whine as Dean
does. Dean smiles softly, looking down at Cas who’s now panting again. Cas
doesn't even open his eyes when he speaks.
“Oh my God, you feel so good,” Cas breathes out, and Dean can't help but laugh
a little.
“I'm glad you think so,” Dean murmurs, nosing Cas’ cheek and pressing a kiss to
it. Cas squirms a little, getting a feel for Dean, who has pretty much smashed
his expectations of what it would feel like to have Dean inside of him. Cas’
brain is kind of short circuiting since this is really really good and Dean
hasn't even started moving yet. But, finally, Cas’ brain gets caught up to the
moment and he opens his eyes to look at Dean.
“Fuck me,” he simply mutters and, okay, Dean can definitely do that. Dean pulls
out and thrusts back in, watching Cas’ reaction carefully. His first few
thrusts are slow, solid, just because Dean doesn't want to overwhelm him, he
knows that this is Cas’ first time and everything. But, Cas doesn't act like it
is.
“More,” Castiel says simply, looking up at Dean. Dean catches the innocence,
the eagerness, and this little glint in his eye that makes Dean's stomach jump.
Dean grins, leaning forwards for a kiss that's all tongue and teeth as Dean
thrusts in a little harder, faster. Cas moans into the kiss that soon turns
open mouthed, the two panting into each other’s mouths as Dean nips at Cas’
lower lip.
Cas pants, feeling every thrust Dean gives him. It’s just what he imagined, but
that doesn't stop him from wanting more. When he's dreamt about this it hasn't
been smooth and sensual; no. It's been rough, it's been hard and gritty, sweaty
and loud, it's been perfect. And Cas is dammed if he isn't going to make it
perfect.
“Dean, please, more, harder,” Castiel breathes into the kiss. Dean groans,
thrusting in even harder, faster, enough to get Cas jostling forwards with
every thrust. Cas brings his hands up to Dean's back, pawing at him as he works
his own hips up into Dean's. Dean kisses down Cas’ neck, biting and nipping at
his collarbone, sucking bruises, knowing that Cas’ shirt will cover them.
Cas closes his eyes once more, wanting to memorize every detail, every thrust,
every feeling that sends shockwaves through him. He can feel Dean sweating
against him, he can hear the little grunts that are falling from his lips with
every time he thrusts into Cas. Cas relishes it all, his bones filled with
pleasure, his body on fire with the pure wonder of it all. He can feel Dean nip
at his earlobe, whispering endearments, telling him how perfect he is, how good
he feels. Cas can barely stand it.
Cas is grateful for the fact that they're in the middle of nowhere because he
knows that he's moaning and he's moaning loudly. Dean's letting lose the
occasional groan or moan, but it's nothing compared to Cas. And then it gets
louder because Dean gets his thrusts just right and hits Cas’ prostate.
“Yes!” Castiel screams, arching up into Dean, clawing at his back. “Oh my God,
Dean, please, right there, don't stop,” Castiel pants. Dean groans, sucking
another bruise onto Castiel's collarbone. “Dean, please, harder, faster, need
it,” Castiel breathes out, tightening his grip of his legs around Dean. Dean
moans, pausing before going at it even harder, giving Cas all he has.
Cas is whimpering and moaning, squirming beneath him and the sight is killing
Dean. “God, Cas, fucking perfect like this, you're so Goddamn beautiful,” Dean
praises, eliciting a little whimper from Cas. Cas is still clawing at Dean like
he's gonna lose him if he doesn't hold on tight enough, and Dean is groaning
into the crook of Cas’ neck whilst he slams in so hard that the car is
rattling.
“Dean, please, please, I'm so so close,” Castiel whimpers. Dean groans once
more, placing a kiss to Cas’ neck.
“Don't worry, I got you,” Dean manages to soothe. He's close too, he can feel
it in the pit of his stomach, heat curling in his belly, threatening to be
pushed over the edge.
Cas can feel the same heat inside of him growing and growing with every thrust
Dean gives him. He's panting hard and so is Dean, he can feel the heat around
them, he can smell sweat and sex and everything is rough, filled with want.
It's everything that Cas has dreamed of, it's more actually. It's perfect.
Cas starts making all these little noises under his breath, desperate little
pleas that grow until suddenly, Cas is shouting, “Dean!” and he's coming harder
than he has in his life, his body arching off of the seat of the car, his lips
parted and his eyes shut tight.
Dean catches the sight and groans, thrusting into Cas even harder, desperately
trying to get where he wants to be.
It takes a handful of thrusts but soon enough, Dean is coming too, just as hard
as Cas, his head thrown back as he lets out a long groan.
Dean has the sense of mind to not fall forwards and crush Cas, so instead, he
pulls out, collapsing on the other side of the car. Both Cas and Dean take a
minute to catch their breaths, and when Dean looks over at Cas he has a dazed
smile on his face.
“You don't know how fucking good that was,” Castiel says, causing Dean to
laugh.
“Trust me, I do,” Dean assures him. Cas shifts, crawling over to Dean and
pressing forwards for a messy, lazy, sweet kiss. Dean pulls him into his arms,
not really caring that Cas still has come all over his stomach. Cas sighs and
curls up into him.
“Thank you, y’know, for being gentle with me and everything. I mean I know that
what we just did wasn't gentle but you were kind to me and everything,” Castiel
says softly, glancing up at Dean. Dean smiles softly and kisses the top of his
head.
“You deserve every bit of it, Cas.”
