****** Third Date ******
by Lucifers_Pony
Summary
     Dean is thrilled to be dating senior Castiel Novak, star quarterback
     and most popular alpha in school. Unfortunately for Dean, Castiel is
     interested in more than making out.

Dean couldn’t believe his luck. He knew he wasn’t bad looking, but he never
thought Castiel Novak, star quarterback and most popular alpha in school, would
be interested in him. Dean was bulky, brash, and loud – all things omegas
weren’t supposed to be. Yet here he was, on his third date with the sought-
after alpha.
If Dean was honest with himself, he was smitten. Castiel’s perpetually mussed
hair and piercing blue eyes did things to the omega. Though Castiel was a
senior and Dean only a sophomore, he found the alpha’s maturity refreshing
compared to the alphas in Dean’s year. And though Dean would never admit it, he
loved that Castiel was a perfect gentlemen: holding open doors for Dean,
insisting on paying, always being attentive. Tonight Dean had watched Castiel
at the football game, followed by the alpha taking him out for burgers. Now,
they were parked at the local makeout spot. Dean’s stomach was in knots, having
never really gone beyond fumbled kissing. He reveled in the buzz under his skin
at the thought of going a little further with Castiel.
The alpha tuned the radio to some soft music before adjusting the heater.
“Is it warm enough for you Dean?”
“Yeah Cas. I’m plenty warm.”
“Good. I want you to be comfortable.”
Dean smiled at that, feeling cozy in the car despite the crisp fall air
outside. Castiel gave him one of his winning smiles, his arm draped over Dean’s
seat, before leaning in and stealing Dean’s lips for a kiss. The omega
immediately leaned into it, enjoying the soft push and pull between him and the
alpha. Cas was never rough with him, but there was always that small
undercurrent of domination, of Cas taking the lead, that Dean loved.
The kiss deepened, Castiel leaning forward and placing his other hand on Dean’s
hip as he angled himself slightly over the omega. Dean gave back as good as he
could, not nearly as experienced but making up for it with enthusiasm. They
kissed like that for what felt like ages, Castiel’s hands gently exploring him
while never straying too far. Dean was in heaven.
Castiel pulled back a bit, cupping Dean’s face and staring into his eyes. Dean
gazed back, dazed by the alpha's skilled lips.
“Let’s push your seat back,” the alpha said, reaching for the lever while
silencing any protests from the omega with the insistent press of his mouth.
Dean found himself in a horizontal position, Castiel looming over him and
peppering kisses along the omega's jaw and neck. Though he liked the position,
alarm bells were going off in his head; he needed to let Castiel know his
boundaries. 
“Uh…Cas…I-I love what you’re doing here, really, but I don’t – I don’t want to
–“
“Shhh…I know Dean. We don’t have to do anything more than this. I just wanted a
better angle to mark you up, let those alphas at school know you’re my
boyfriend.” The alpha looked down into Dean’s eyes at that, searchingly. “Is
that okay? I mean, would you like to be my boyfriend?”
Dean felt his heart pick up, thrilled at the alpha’s words. Cas wanted to be
his boyfriend?
“Of course Cas.” Dean smiled up at him, running a hand through the alpha’s
unruly hair with tenderness. The alpha smiled back before leaning down to claim
Dean’s lips again, kissing him solidly and breaking away every once in a while
to nip and suck along Dean’s neck. Dean knew his dad would flip if he saw the
bruises, but he’d just have to cover them up. He wouldn’t stop this moment for
the world.
Soon Castiel’s hands began to wander again, this time inching under the omega's
shirt. Dean felt uncomfortable, but the alpha’s hands stayed firmly above the
waist, and it felt so good when he began to massage and tweak Dean's nipples.
When the alpha sucked a sensitive spot on Dean's neck in tandem with
his kneading, the omega made a breathy mewling noise he was immediately
embarrassed about.
“Mmm, don’t hide those beautiful noises from me baby,” the alpha on top of him
whispered in his ear, nipping at the lobe. Dean couldn’t help but moan at that,
letting little whimpers slip out as the alpha continued his ministrations. He
felt himself growing hard in his jeans from the stimulation, and blushed as he
felt a bit of slick leak out of him. He soon became lost in another kiss,
barely noticing as the alpha’s hand wandered downward beneath his jeans. He was
jolted back to reality when he felt a hand close around his cock, stroking him
beneath his pants.
“Cas – wait, I don’t –“
“Shhhh” The alpha silenced him with another kiss. “I just want to make you feel
good Dean. Nothing more than a handjob. Come on, baby. Let me make you feel
good.” The alpha leaned in to invade his mouth again as the hand continued
stroking. Dean pushed meekly against his chest but eventually found himself
thrusting weakly into the alpha’s hand. He was right. It did feel good. Wrong,
but oh so good.
Dean let it carry on for what must have only been a minute or two—though it
felt like an eternity for the omega—before the alpha was removing his hand.
“Here, let me remove your jeans. They’re too restrictive. I want to make this
good for you.”
Dean stared up at the alpha with wide eyes. He was hesitant. He really didn’t
want to take off his jeans – they had already gone further than he was
comfortable with. But the alpha cupped his face, stroking his cheek and staring
down at Dean with that piercing gaze.
“Please baby. I just want to make you feel good. It’s what good boyfriends do.”
Dean was a bit resentful of that, the way he brought up being boyfriends at the
end. But he didn’t want to mess things up with Cas, and the alpha had already
touched his cock – what difference would it make if he took off his pants too?
The omega began to unbutton his jeans, and Cas helped him pull them down in the
confines of the car. To Dean’s surprise, the alpha dragged Dean’s boxers down
with them. Before Dean could protest, Castiel had settled between his legs and
resumed their makeout session. Dean was tense as Cas continued to stroke his
cock, but under the alpha’s talented tongue and hand he was
quickly overcome with pleasure. He had barely played with his dick save a few
short jerk-off sessions in the shower; it felt amazing to have someone else
touching him there. He closed his eyes and became lost in the sensual kissing,
his boyfriend’s touch, and the soft music playing in the background.
Soon Dean was rapidly leaking slick, and he briefly felt bad for the car’s
upholstery. But Castiel didn’t stop. In fact, he seemed excited by it. He
deepened the kiss, and Dean felt a finger begin to breach his hole as Castiel
strengthened his strokes on the omega’s cock. Dean tried moving away from the
digit, but Castiel was quick to utter sweet nothings and reassurances while
reclaiming Dean’s lips with his own. His kisses were more insistent now, more
dominating, and while Dean wanted to protest, he was all too distracted by the
alpha’s sinful lips and tongue. The double stimulation quickly had him swimming
in a hazy sea of pleasure, only intensified by the heated nature of the kiss.
Dean was so lost in it all, in Castiel, that he didn’t register that the alpha
had added a second finger. More fixated on the way his moans were swallowed by
the alpha’s plundering mouth, he mindlessly shoved back on the fingers in his
ass as they stretched him. His pleasure was swiftly reaching a crescendo, and
he was so focused on getting there, of reaching that point of pure ecstasy, he
missed the fingers being removed from his heat, and the sound of a zipper being
undone.
Dean was brought back to reality when the hand was suddenly removed from his
cock, the omega thrusting uselessly into air at the loss. It was only then he
noticed Castiel had shifted over him, pushing himself closer, his hand now
bracing the alpha up as Dean felt a blunt pressure insistently pressing against
his hole.
 “Cas – what are you, what –“
But Dean’s words were cut off by a yelp of pain as the alpha suddenly shoved
into his body. All of Dean’s pleasure vanished as it was replaced with a
searing pain. The alpha was big, too big, invading him too suddenly, stretching
him open. Dean felt tears begin to form in his eyes, struggling and pushing at
the alpha above him as he desperately tried to get away.
“Stop – stop – take it out, Cas, get it out of me –“
But Castiel paid him no heed, his face twisting in pleasure as he pinned Dean
down and forced his way further into the omega. Dean gasped at the pain,
feeling full, too full, as the alpha’s cock continued to spear him open. He
knew Cas was already too deep inside, that he wasn’t able to twist away, but he
still struggled beneath him, crying and begging him to pull out.
With a satisfied grunt Castiel finally settled balls deep in the omega. He
paused, giving Dean time to adjust, stroking the omega's sides and whispering
soothing reassurances. Dean barely registered the alpha's platitudes, Castiel's
murmurs of how he was going to take care of him, make him feel so good. The
omega felt stuffed, fuller than physically possible. It was too much, all too
much. He wanted, needed it to be over, and he continued to beg and shove at the
alpha trying to get him off of him. Castiel’s face soon morphed into annoyance,
and Dean saw the alpha roll his eyes before leaning back to adjust the radio
station and crank the volume. Suddenly Dean found his cries drowned out by the
chorus of a rock song he didn't recognize, the stereo’s vibrations shaking the
vehicle with their intensity. The alpha turned back towards Dean, a small smile
on his face as he firmly held down Dean’s arms and locked eyes with the omega.
Dean gazed up at him, the alpha making sure Dean was watching before slowly
pulling out halfway and purposefully, powerfully, thrusting back into the
omega. Dean clamped his eyes shut, the realization that the alpha really wasn’t
going to stop washing over him like a tidal wave that would surely drown him.
The cock invading Dean’s ass began to slowly saw in and out of him. Castiel
took his time, his thrusts measured and methodical. The violation consumed
Dean, filling him with shame. Castiel greedily stole pleasure from the omega’s
body, defiling him and his innocence just so he had a warm place to get off in.
Dean didn’t want this, any of it, and the cock repeatedly spearing his ass open
was a constant reminder the alpha didn’t care. No, Castiel ignored Dean’s
whimpers, instead draping himself over the omega’s body and burying his face in
Dean’s neck as he slowly continued to screw him.
Dean could do nothing but lie there and take it as the alpha fucked him deeply.
Castiel seemed to enjoy showing off his strength, making sure Dean felt it as
he put power behind his thrusts. Eventually, the omega’s ass became accustomed
to the intrusion, the burning pain from Castiel’s thrusts slowly morphing into
a strange, unknown sensation. The omega shivered as the alpha licked a long
stripe along his neck, turning his head away in disgust. Castiel simply rested
his face against Dean's, positioned so his mouth was right next to the omega's
ear. This way he was draped over the omega, making him feel the weight of his
body. Making sure Dean heard his grunts of pleasure, forcing him to listen to
Castiel enjoy his body. The grunting was soon joined by pleasured panting as
Castiel increased the speed of his thrusts. Dean started to notice warmth
spreading through his lower body, seemingly radiating from his ass. When
Castiel leaned back to lick a humiliating stripe up the length of Dean’s face,
the omega shivered for a different reason.
The song on the radio changed to Closer by Nine Inch Nails, and Castiel seemed
pleased by it. Dean noticed the alpha picking up speed, beginning to fuck
him along to the beat. Soon the entire car was rocking from the strength of
Castiel’s thrusts, Dean being pounded into the seat beneath him. Castiel would
occasionally brush his prostate, but it was the force of the alpha’s thrusts
that had Dean grunting on every stroke. Castiel smiled smugly at the sounds,
fucking Dean harder. Soon he propped himself up to get a better angle, and the
adjustment had him hitting the omega’s prostate on every thrust. Dean saw
stars; he couldn’t hold back a loud moan at the change, becoming lost in the
the music as he was plowed by the alpha.
“There we are.” Castiel groaned, bending down to murmur in Dean's ear. “You
omegas are all the same. Starting off meek and playing coy, but as soon as an
alpha gets you on your back and between your legs, you moan like a whore for
them.” Dean clenched his eyes shut at that, turning his head in humiliation. Of
course Castiel had done this to other omegas. Why did he ever think he was
special?
“Oh don’t be like that baby. Moan for me. Moan like the little whore you are.”
Castiel increased his thrusts, now humping wildly into the young omega below
him. Try as he might Dean couldn’t hold back the sounds of pleasure escaping
him as Castiel purposefully hit his prostate on every stroke. His arms reached
forward and wrapped around the alpha’s neck without Dean’s conscious
permission, desperately holding on as Castiel pulverized his ass. Dean felt
like he was outside his body, hearing his own moans as if they were someone
else's, obscene and pornographic to his ears. He closed his eyes to avoid the
smug smile he knew he would find on the alpha’s face.
Dean soon felt a knot begin to press against his rim. Distantly he wondered why
the alpha wasn’t slowing down. Castiel wasn’t going to knot him, was he?
Knotting was considered deeply personal, usually reserved for mated couples.
Largely because it almost guaranteed the omega would become pregnant. Knotting
outside of a serious relationship was virtually unheard of, taboo even. But
Castiel didn’t slow down, and Dean’s began to panic as the alpha’s growing knot
thrusted in and out of him.
“P – please…Cas, please, I’m not – fuck – I’m n – not on birth control. You –
you have to pull out.” Dean’s voice was weak from use, barely able to get the
words out. There was no way Cas could hear him above the music, but the alpha
seemed to realized he was trying to say something. He leaned down, putting his
mouth against Dean’s ear, panting into it “You’re going to have to speak up
sweetheart.” Thankfully, he tilted his head near Dean’s mouth so he could hear
him. Dean weakly ground out a second time between moans, “I – I’m not on birth
control. Ah. Please. You n – n – need to pull out.”
The alpha leaned back and looked down at him, grinning like the cat that caught
the canary. His thrusts became more eager, the alpha losing his rhythm as he
seemed to try and bury himself as deep in the omega as possible. 
Horror blossomed in Dean’s chest as he realized the alpha wasn’t going to slow
down, that he seemed excited at the prospect of knotting him. Dean was way too
young to be a parent. He wanted to finish school, get a job - find a mate and
get married before starting a family. He didn’t want to get knocked up at
sixteen by a high school quarter back fucking him in a car.
But Castiel was still pinning him down, and though Dean pushed weakly against
his chest, he was powerless to stop the alpha as he fucked him harder and
harder. Soon Dean felt a knot, impossibly large, forcing its way into his ass.
The stretch obscene, Dean was blinded by a mix of pleasure and pain as Castiel
finally slammed his way home, locking his knot into the omega and coming with a
filthy roar. Dean couldn’t help the burst of pleasure that exploded behind his
eyes at the feeling, his ass instinctively clamping down and milking the knot
inside him as he came. He felt cowed, fucked into submission by the alpha still
rutting desperately inside him. The alpha who was breeding him. He came down
from his high to the sound of Castiel’s appreciative moans, shivering as load
after load of come was dumped inside of him. He groaned at the feeling.
Soon the alpha was satisfied, resting for a moment before leaning back and
silencing the radio. Dean’s heartbeat sounded ridiculously loud in the silence,
only accompanied by a backdrop of heavy breathing.
“You were amazing, sweetheart.” The alpha panted over him, reaching forward to
gently stroke the omega's hair. “You did so well for me. Such a good boy. Not
even on birth control. I mean, I love the feeling of knotting a bitch any day,
the intimacy of it all, but knowing I would knock you up…what a gift.” He
rutted into Dean at that, groaning as another stream of come emptied into the
omega. Dean didn’t respond, too exhausted to argue. Castiel didn’t seem to
mind.
“Don’t worry baby. I haven’t lost interest now that we've slept together. I
won't judge you for giving it up on the third date.” Dean felt a sob rip from
his throat at that, but resolutely held himself back. He wouldn’t give Castiel
the satisfaction.
The alpha hummed softly to himself after that, rocking into the omega as he
waited his knot out. Dean laid there in silence, pointedly looking away from
the contended smile on the alpha’s face. After about thirty minutes he finally
felt the alpha’s knot deflate, but much to his dismay Castiel did not pull out.
Instead, he began to rut into the omega once more. Dean didn’t even bother to
fight, simply laying there as he felt Castiel grow hard again inside him. Soon
the alpha was fucking him in earnest. Dean closed his eyes and listened to the
loud squeaking of the car as it rocked back and forth, previously drowned out
by the music.  He had a feeling the sound would haunt him. As Castiel’s pace
picked up he opened his eyes, staring blankly at the ceiling as the alpha
plundered his ass. Castiel didn’t seem bothered by it, grunting
enthusiastically as he used him like a ragdoll. Eventually he forced his knot
into Dean a second time, surprising the omega by leaning forward and claiming
his mouth in a kiss as they tied. Dean didn’t resist as Castiel invaded his
mouth, those sinful lips both tender and passionate. As if what had just
happened was beautiful, wanted. As if they had made love.
This time the alpha’s knot went down much faster, and Dean was relieved when he
pulled out of him. That is, until there was a tap at the window. Dean balked,
worrying about who might have seen them. But his chest flooded with relief as
he saw it was the Sheriff. Finally, he was saved.
Castiel unlocked the door, which the Sherriff opened before peering into the
car.
“Alright, son. You know the drill.” Dean was confused, but didn’t question it
when Castiel wordlessly got off of him and exited the car. He began to sit up,
but found himself being pushed down and another body settling between his legs.
“Be careful with him, dad. I already knotted him twice.”
Dad?
Dean barely had time to register it was the Sheriff on top of him before he
heard the sound of a zipper being undone and was unceremoniously shoved
into again. Dean began to cry as the Sheriff, a man old enough to be his
father—Castiel’s father, his mind supplied—began thrusting into him.
“You sure picked a pretty one this time, Castiel. I have to admit I’ve been
eyeing the Winchester bitch for a while now. I know you want to sow your oats,
but you should consider claiming this one. Such a tight little ass, you’ll be
able to get years of good fucks out of him. I mean hell, he’s like a vice
around me.”
Dean closed his eyes, trying to drown out the pleasured grunts of the man above
him as he was fucked for the third time that night.
“And look at how pretty he cries. You’re not fighting me at all, are you,
darlin’? Letting a strange man come in here and fuck you, just like that. I can
already tell you're a special one. If you don’t claim him Castiel, I just
might.”
The Sheriff pumped in and out of him faster, pausing momentarily to lift Dean’s
legs and place them over his shoulders. Folding the omega in half, he began to
thrust wildly, face inches from Dean’s as he panted and grunted in pleasure.
Dean laid their limply, eyes clenched shut as he tried to block out the sounds
of their coupling. He briefly wondered if Castiel’s father would also manage to
put a pup or two in him as the Sheriff fucked him faster and harder, his knot
beginning to form as he buried himself repeatedly in the omega.
