Castiel has lived for a very, very long time. In that time, he has done a great many things. He's fought in every famous war, and some wars that were less well-known but no less significant. He's courted royalty, rubbing elbows with nobles of any number of courts. He's also frozen with peasants, gone hungry with the poor. Castiel has committed any number of depraved acts with any number of depraved beings.

But here, now, watching himself slowly sink into Dean as the boy absolutely falls apart beneath him, he can't think of anything more wicked than the way this feels at this moment.

"Cas," Dean is babbling. "Fuck, fuck, you're so fucking big, fuck, love your cock. Holy shit, Cas, holy fuck-"

Castiel has hardly ever been able to find it in himself to deny Dean, so he finally puts his hands on those slim, lovely hips and thrusts into him hard, bottoming out and moaning at the tight, wet heat. Dean cries out and drops down to press his forehead to his arms, arching his back for Castiel.

"So good for me, dearheart," Castiel murmurs as he pulls out and thrusts in again, using his supernatural strength to hold Dean in place when he would rock back onto him. "Always so lovely, just incredible."

"Cas." Dean's gasping whine is bordering on desperate, so Castiel once again gives in and starts to fuck Dean for all he's worth.

There's always a measure of control required when they're in bed, but two years later, it's second nature to make sure that he doesn't permanently hurt Dean, but that he does fuck him hard enough for him to feel it the next day the way Dean likes. The sound of Dean's breathy moans and the way his body pulls Cas in and seems to try to keep him in as he withdraws has his own orgasm building in his gut, buzzing beneath his skin. He bends to press his chest to Dean's hot back (he's always so hot, so white hot compared to me) and wraps an arm around him. He presses his lips to Dean's ear.

"So lovely," he rasps. "Are you going to come for me, Dean?"

"Cas!"

He runs his hand down Dean's flat belly so he can wrap his fingers around his cock. "Can you feel it, Dean?"

"Ca-as," Dean whines.

"Tell me, dearheart. Can you feel it? I can. You're going to come for me, aren't you?"

Dean tilts his head, baring his neck. Despite the desperate way his body is moving, Cas can see the smirk has on his face. Impudence, he thinks, though his attention is immediately glued to the fluttering pulse in his boyfriend's neck. In this state of heightened awareness and instinct, he's helpless to do anything else.

"Come on, Cas," Dean pants, outright grinning now. "Wanna come with you inside me."

And even though his cock is as deep as it can go, Cas knows exactly what Dean means, so he doesn't bother to smother his growl when he turns his head and sinks his teeth into the vein in Dean's neck.

The earthy, lovely taste of Dean explodes on his tongue, making his vision go hazy and his growl deeper as he has to fight the urge to bite down harder. Instead, he closes his eyes to savor Dean's blood filling his mouth and Dean's ass clenching around his cock.

He can taste the hormones in Dean's blood change, telling him that Dean is coming as surely as the pulsing of his cock in Castiel's hand and the warmth of his release spilling over his fingers. Combined with the way his ass clamps down on Castiel's aching cock, he finds that he barely has the presence of mind to withdraw his fangs so he doesn't mutilate Dean before his orgasm hits him like a freight train. He closes his eyes and presses his forehead to the back of Dean's neck as waves of ecstasy wash over him.

After what seems like an age, but is probably only a few minutes, Castiel tips them over. He makes sure to keep Dean out of the wet spot and holds him close, reveling in the blazing heat of the beautiful human in his arms. He also makes sure that he's still inside Dean. Because he has no blood of his own, no real pulse, his erection stays hard longer after orgasm than a human's, and Dean likes the feeling of having Castiel's come plugged up in him.

Almost as much as Castiel himself likes it.

Dean cuddles back into him, covering Castiel's arms with his. He hums in contentment, and Castiel feels the vibrations of it in his own chest. He manages to wrangle one of his arms away so he can get a wet wipe out of the nightstand table to clean Dean gently. He'll take care of himself as soon as he's gone down enough to slip out of Dean without causing him discomfort.

He presses gentle kisses to Dean's strong shoulders, overcome with affection.

"Sap," Dean says sleepily, a smile obvious in his voice.

"Always for you, dearheart."

"Ugh," Dean complains, but he presses closer to Castiel as he drifts off.

Castiel waits until he is absolutely certain that Dean is deeply asleep before he speaks.

He whispers roughly into the dark, the only time he feels comfortable speaking the words out loud to his lover, because although Dean has come a very long way in two years, he's still "allergic to chick flick moments," whatever that means.

"In all the time I've been alive, I've never loved anything as wholly as I love you, Dean Henry Winchester. I will spend the rest of our lives together proving it to you, and shall be glad of the task every day."

He says the words to Dean's sleeping form every night, and holds his beloved until he wakes, feeling every inch the giddy, lovesick fool he is.

"I'm gonna miss mornings," Dean muses over coffee the next morning. "When I turn, I mean."

In the last two years, Dean's body has filled out a bit. He's still tall and slim, but Castiel can tell that his shoulders and chest will become broader, more muscular, in the years to come. He has a few scars from Alastair's attack, one above his eyebrow and a long one on his left side, but his skin is otherwise unblemished. He's perfect, scars and all.

"We still wake in the mornings," Castiel answers. "We just don't go out into the sunrise."

Seemingly in response to the words, Dean shifts on his feet until the sunlight drapes itself over his golden torso through the window above the kitchen sink. "I know," he says lightly. "I'll just miss the warmth is all."

"We'll keep the heat on," Castiel says with a smile.

Dean chuckles, and Castiel is entranced, as always.

"Smartass," the human says into his coffee, eyes sparkling over his mug.

"You're one to talk."

Dean rolls his eyes and turns back to the stove where he has French toast frying in a pan. "What's on the docket for today?"

Back to business. "Gabriel called yesterday from Rome. He's confident that he's found a lead to the cult Alastair must have belonged to."

"The ones calling themselves 'Lightbringers,' right?"

"Indeed." Castiel fights to keep his mood even instead of letting it darken with irritation.

"Hey." Dean's gentle voice has him looking up to meet warm green eyes (everything about him is warm and soft and lovely).

"We'll figure it out, okay? We'll get to the bottom of this, babe."

The pet names warms him, as always, and has the desired effect of banishing his dark thoughts.

"Besides," Dean says brightly (always so bright), "I'll be a fellow creature of the night soonish, and I'll be able to actually do something."

Castiel frowns. "You've provided a great deal of assistance."

Dean rolls his eyes as he slides the piece of toast onto a plate. "Yeah, yeah, I'm a real help during my two hours of free time a week. Not to mention no one will let me actually investigate anything, yet."

It's true that Dean's schooling and job still take up a majority of his time, but he's about to start his last year for his bachelor's degree. Castiel is incredibly proud of him, enamored with how viciously smart Dean is, despite his own insistence to the contrary. Dean, however, just resents how much actual time school takes him.

It's also true that Castiel is wildly uncomfortable with the idea of Dean investigating or interviewing anyone in regards to Morningstar while he's still human. If Castiel could dream at all, he's certain he would still be plagued with nightmares about not getting to Dean in time, or getting to him just to find him already dying, with no option left to him but to get Dean to let him turn him. Until Dean is more than human, Castiel has put his foot down, which Dean has ungraciously accepted.

Dean does want to turn, tough. He wants to wait until he "looks less like a Ken doll, dude." Castiel doesn't really know what that means, because he thinks Dean is the most beautiful thing he's ever laid eyes on, but it's Dean's decision, not his own, so he'll wait.

If vampirism was more like it was in popular culture, he might be uncomfortable with the idea. But since a sire has no real power over newly turned vampires, except for maybe sentimentality, he'll have no actual power or supernatural influence over Dean. Dean will make the decision to turn on his own (not like me wasn't a choice wasn't myself wasn't my choice), and he'll make every decision after that on his own, as well. So maybe he would argue against it if circumstances were different, but as it is, he's eager for Dean to be a bit less fragile.

"We have time," Castiel says simply. "The Lightbringers aren't going anywhere."

Dean snorts as he pours syrup over his breakfast. "Yeah, we're not that lucky."

Yes, Castiel is very worried about the things Alastair said, both to himself and to Dean. What little they've been able to discover about Lightbringers, a fanatic cult with little regard for humanity, has alarmed him greatly, and he's gone to several Elders to find more information and to gather strength. Balthazar and Gabriel are travelling the globe to investigate. It's a serious problem.

But for now, just for now, watching Dean hum happily as he shoves a square of French toast in his mouth, wearing a pair of briefs Castiel is fairly certain were his own at one point, he is at peace.

They do not have any of that "welcome mat" nonsense.

- Here we are, at the end of Come On In. I can't tell you guys enough how crazy it was to watch this story just explode in popularity. It kills me. There are no words to thank you enough. I love you guys.
- "But wait," I hear you say. "What's with these Lightbringer dudes? Who is the 'she' Alastair so ominously mentioned? What's with Cas' crazy inner dialogue? WHAT'S HAPPENING?!" Well, fret not! I'm planning a sequel! I'm gonna take a couple of weeks away from this universe, but I promise there will be at LEAST a third part of this series. I hope you love it as much as you love Come On In, and you can follow me updated once I get the first chapter posted!
- As always, thank you so much. I wouldn't be doing this without you crazy bastards. *heart eyes at you guys*
