"Cas, buddy? I really need you...

"I didn't mean to make you upset. I'm so sorry…

"Come on, Cas. Let's just…let's just talk it over…

"Cas, please…"

The prayers go unanswered for some time. It seems that Dean is speaking to nobody now and that really, really worries him. His heart is heavy and his fear is high; nothing will help except seeing Cas and knowing he's alright. Part of him is concerned that maybe Cas isn't ignoring him on purpose and maybe the heat has killed him?

"Dean, Dean. Check this out."

Sam comes into their current motel room with a dirty old book in his hands. Dean just sorta looks over his shoulder at him and acknowledges him silently. Another prayer without a response and he barely has any energy left to care.

"I think I found something on your problem."

"Wait, what?" Dean has Sam's attention now. He turns around on his bed and leers at the book that Sam is opening. He puts it on a table and begins to leaf through.

"There's this really obscure myth about angel season, part of the nephilim lore."

"Angel season? Uh, okay…"

"Apparently when angels fall in love, their vessels go through this weird change. It might be what's going on with Cas, listen to this," Sam begins to read the tiny old font. "'It has been noted that true love, when absorbed by the celestial being, will set a chain reaction called angel season. Every fifth year starting the day that the angel met its true love, season runs for a month or two. During this time does the vessel communicate with the true form of the angel and open itself for true conception.'"

"Wait, conception?" Dean raises his eyebrows. "What the heck is this talking about?"

"It's, well," Sam stutters to explain. He's getting ahead of his own thoughts. "Okay, let's say that, hypothetically, you were a woman."

Dean glares at Sam and doesn't answer.

"When Cas has sex with you, he could theoretically get you pre—"

"Woah, woah woah," Dean interrupts angrily. "Are you trying to suggest that Cas puts his dick in me?"

Sam looks up from the book and stares at Dean, blinking in confusion. "Uh, yeah I guess?" Dean takes great offense at this assumption. "I don't think about this stuff, sorry," Sam apologizes quickly.

"You better be sorry."

"I am, I am," Sam says with a sigh. "Okay, let's say Cas took a female vessel. Is that better?"

Like a brat, Dean smiles halfheartedly and hums "yes."

"Then if you had sex with him, uh, her, you could in theory get her pregnant, right?"

"Yeah, sure."

"But the baby wouldn't be you and Cas'. It would be you and the vessel's. Cas doesn't have his DNA in the eggs of the vessel."

"Okay," Dean says, nodding. He's catching on.

"So apparently during this angel season thing, the true form of the angel breaks through and acts like a fertilizer to the sperm or eggs of the vessel. It pumps them full of grace and they're infused with the angel's true form. So then when they have a baby with the 'true love', the kid will have grace and be half angel. A nephilim."

"Well that's great and all, but what the heck does it have to do with me and Cas?"

"You guys happen to both be male, so you can't get pregnant. Cas goes into season and he tries to reproduce but he can't, then you just have crazy sex and call it a day."

Dean frowns a little bit. "So you think Cas really cares about me or it's just his angel period?"

"God, Dean. Are you listening at all?" Now Sam looks a little frustrated and he points at the book, reading again. "'Every fifth year starting the day that the angel met its true love, season runs for a month or two.' True love, Dean. True love."

A long breath of air runs out between Dean's lips and he glances around the room briefly. That's a lot to take in and most of it sounds like a fairy tale. Sam keeps reading a little more as Dean chews over his next move.

"Okay, but hold on," Dean says. Sam takes his face away from the book. "It says it happens on the day they met, right?"

"Right."

"Well we met in September. It's March."

"Hmmm, true," Sam says with a pensive nod. He thinks for a moment. "It might not be totally accurate, you know. I mean, when did Cas start his season? If it's subsiding now, it was about a month or two ago."

"Yeah, yeah. He was acting funny starting around my…"

Dean's voice trails off and his face turns pale, then his eyes redden. Sam gets off of the chair and comes over to his brother's side. "What?" he asks. "Around what?"

Heavy eyelids press together and Dean does everything he can to hold back tears. He turns his eyes up to Sam and parts his lips, then a small low voice mumbles, "around my birthday."

Sam thins his mouth and looks down. "You think Cas met you…"

"Yeah," Dean sniffs. "I….God, I really need to get through to him."

"Try praying."

"He won't come if you're here. Could you make yourself scarce for a bit?"

"Yeah, sure," says Sam. He smiles sadly and gets up, takes the old book from the table and leaves Dean alone in the motel room.

There, Dean sets his elbows on his knees and, trying to pull back his tears, whispers "Cas, please. I know you're mad but I gotta talk to you. This is really, really important. I just…God, baby, I need you. Please, Cas."

Finally a response. The room thickens and Cas just says, "Dean…"

Dean turns around and the moment he sees the angel there, he gets up and runs to him. He wants to hug him but given the tension, he holds back. Instead he looks him top to bottom and sniffs. "Cas, have you been drinking?"

Heavily creased and darkened eyes, Cas staggers and glares at Dean with a slight hint of anger. "I spent eternity searching for my other half," he mumbles in a groggy voice. "When I think I find him, he doesn't even love me back."

"No, Cas, I…I…" Dean tries to speak but when he looks into Cas' eyes, the sad, blue wells are too intense. He has to take his sight somewhere else. Both of their bodies stand there awkwardly. It's amazing to consider how just days before they merged so beautifully and without any hesitation.

Emotions whirl within Dean harder and faster than they ever have before. Why is it so difficult to be honest? What is he afraid of? It's Cas, after all. He's nothing more than a multidimensional wavelength of celestial intent, packed within a fragile human body, teaming with confusing hormones and already pissed at Dean. What could possibly go wrong?

"Cas, no, I…" Still hesitating, but it won't come out. Cas stands there and stares back at Dean, half expecting something fantastic but also recognizing that Dean is Dean.

Enough.

Dean opens his arms real wide and grabs Cas. He hugs him tight. He holds onto that angel's vessel and brings him to his chest, squeezing firmly like he doesn't ever want to let go.

"I do love you, Cas. I love you so much. I've always loved you."

Honesty feels good but it comes with a price; Dean starts to cry. He cries and cries, happy tears but tears nonetheless. His hands rub up and down the dirty trench coat passionately, feeling the muscles beneath. All Cas does is hug him back awkwardly and rest his head on Dean's shoulder, still shaking a little from intoxication.

"I love you very much, Dean."

"Oh, Cas. God. I…I'm so sorry." Dean squeezes Cas' body against him so tight. He wants to hold him and never, ever let go. "Oh, Cas…Cas…Cas, baby, I love you so much."

Cas' cheek rub against Dean's tenderly. He closes his eyes and reaches up to wipe some of Dean's tears away. "There's no reason to cry," the angel says quietly.

"I know, man," Dean says, chuckling with nervousness. "I just feel like a real dick."

"I understand," says Cas. His fingers run around the rim of Dean's ear gingerly, scanning the surface like a study in the smallest details of anatomy. It feels good and Dean just sighs, closing his eyelids so he can focus better on the sensations of Cas' touch, inhaling the strong odor of alcohol on his clothes. "Honesty is not the easiest concept for you."

"Tell me about it," Dean sighs. Admitting that alone is more honesty than Dean is used to. It's nice to feel this safe with Cas; he's never been so emotionally vulnerable but it really isn't that bad.

Though Dean's heart is heavy with love and he is content with only holding Cas, the angel is still quite antsy with his heat. His season starts to whip up within him and he grabs Dean by the wrist, yanking the whole arm down and to his own rear.

"Cas," Dean says with a little hiccup in his breathing. The angel doesn't reply. He pulls Dean's hand underneath the trench, the suit blazer and into his pants, along his ass cheek and to the center. Dean swallows tight and moves his head back to look Cas in the eyes. Their eyes lock and Cas gives him a desperate, naughty stare. Those fat, pale lips separate wantonly with a thin sliver of tongue pushing through. Dean can't resist. The moment his finger rubs down between Cas' crack he also plants a kiss right on his lips. The instant they meet, Dean slams Cas back against the wall, clutching his ass hard and turning into the kiss with a sudden fervor. Having given all power over to Dean, Cas releases his wrist and wraps both of his arms around his shoulders, pulling him close to intensify their kiss. Small moans, increasingly rapid breaths and deep grunts sound between the both of them, grinding and pressing together as the heat grows.

Dean's middle finger slides around Cas' hole, teasing it from the outside for a bit just before it pops within. Cas instantly grasps the fabric of Dean's shirt, tugging at the dark plaid as he sends moan after moan into his mouth. The freckled finger makes its way deeper and deeper inside, rubbing in tight circles that drive Cas wild and grow both of their erections hard. Their lips part momentarily and Dean whispers, "Take our clothes off." Cas nods, eyes closed, and zaps them both naked.

Dean pulls his finger out of Cas and grabs both of his legs, thrusting the angel back harder to the wall as he lifts him up. The muscular yet lean legs of Cas hook around Dean's waist and grapple hard, squeezing him with thick desire.

"Dean," Cas moans. His fingernails dig into his lover's shoulders, leaving hot pink trails behind as proof of his neediness. "Dean…"

Dean's face burrows against Cas' neck now, running his tongue up to his cheek where he stops at the ear and whispers, "You want me to fuck you?"

"Yes, Dean, yes!" Cas cries out. Sweat begins to bead down his strong forehead, dampening his dark hairline. Dean works his erection between Cas' cheeks, teasing so well with the steady movement of his hips. "Oh, Dean! DEAN!"

It's all a bit too much for Cas and he pivots his hips to rub his asshole on the end of Dean's cock, wiggling himself with a quiver that needs him. He requires penetration.

"I gotta lube up," Dean says in a huffy breath.

"No, no!" Cas moans. "It doesn't—matter—I need you—Dean…"

"If you're sure," says Dean.

"Yes! Ah! Noib! Noib!" Cas shakes mightily as he cries out in Enochian. Obviously it's harder for him to convey himself with the presence of alcohol in his bloodstream. "Iolcam daxil! Dean! Niis!"

Dean seems to understand Cas' pleads for sex, maybe it's just inferred or perhaps he's picking up some sort of wavelength, but either way he presses himself inside the angel now. It's tight, super tight, but he squeezes inside regardless. A little spit on his fingertips then rubbed around on his shaft helps out a bit, just to get the sensation stronger for him. Cas doesn't mind; he loves all of it. He's drunk on love and booze. Any way that Dean is within him feels good.

So once Dean manages to fit his entirety inside, his holds Cas hard by the waist and thrusts up to him. His cock grinds against Cas' prostate, causing him to clench tight and scream even louder. The sensation is so magnificent and now knowing that Dean has said I love you, he enjoys it all the more. They both enjoy it more. Their sweaty bodies collide, panting and groaning, twisting and aching with intense pleasure that the heat bubbling within feels like it's going to burst. Thin streams of red run down Dean's back as Cas claws into him harder. His legs flop around his waist with each thrust, sending his head back on his shoulders and moans oozing from his moist lips. "Givi, givi," Cas beckons, hissing a bit of angel sine wave with it. "O ipam doalim!"

"I don't—unff—understand you," Dean groans. He opens his eyes just a smidgen and sees that bright blue light is flickering beneath Cas' eyelids. "You okay, baby?"

"YES, DEAN! DEAN!" Cas screams. He grabs the man even harder, rocking and bobbing his ass against his crotch. Violent thrusts are had by both as they heat up together even greater. "DEAN! DEAN! AAH! GE QUASAHI I DRILPA!"

"Damn it, Cas! Damn! DAMN!"

Dean holds on tight as he feels his load building up. Long, grinding thrusts pull in and out of Cas' pink hole, bringing throbs and aches deep in his shaft. Cas starts to whimper now, quivering all over. For a brief moment they are both engorged in psychotic ecstasy. Cas' body is slammed against the wall, banging loudly as Dean pounds him hard. They grab and claw at each other, meet in the middle for a hot, sloppy, wickedly messy and intense kiss to kick off the twin orgasms. Dean bites down onto Cas' lower lip when his load is shot deep within him. Moans come from them both. They cry, twist, entangle each limb in any way possible while every vein is shocked with pleasure.

"Baby," Dean gasps. He breaks the kiss and presses his forehead hard against Cas'. He smiles. They smile. They hold onto each other tenderly and just smile. No words can be said. The moment is beautiful. "I love you."

Cas sighs loudly and pulls off of Dean. "Set me down," he says, coming to his senses a little better now. Dean nods and puts Cas on his feet. "Thank you, Dean." Cas tries to walk forward but he stumbles back and thuds against the wall.

"You okay?" Dean asks.

"Yes," says Cas. He blinks and looks at Dean, tilting his head. "Many feelings but they're good."

Dean smiles and touches Cas' cheek lightly. "Cool," he says, then goes over to where their clothes have been neatly piled on the bed and starts to get dressed. He steps inside his underwear and looks at Cas over his shoulder. "Hey uh, Cas?"

"Yes, Dean," Cas says. He looks up at the ceiling with an almost tired expression. Dean can't stop gazing at the beautiful naked body. Damn, he is beautiful, right?

"This uh, thing that Sam was telling me about. Angel season? Apparently you guys get fertile or whatever every five years after finding true love. Sound like our problem?"

"Possibly," says Cas, nodding with a pensive face. "This is news to me."

"That's what Sam found. But uh, I gotta wonder, man…" Dean pulls his pants up now and slides on a t-shirt, then scoops up Cas' clothes and brings them over to him. "When did you first meet me?"

Cas clears his throat. "Time ago," he says quickly.

"Eh? Time ago? Like uhh, I dunno, maybe, my first birthday?"

The angel doesn't answer. Dean gets up into his face and smirks. "Hm? Yeah?"

"I possibly peeked through your dimension when you were born."

"Ah," Dean says with a nod. "Alright. Cool. And uh, why?"

"Because I felt something special inside me when you were born, Dean."

Dean blinks slowly. He smiles a bit and looks at Cas. "That's creepy but kinda cute," he says. Cas nods.

"I've always been watching you. It was your mother's wish."

Dean shoves Cas' clothes into his arms, pats him on the shoulder and kisses his cheek quickly. "That's nice," he whispers. "Thanks, Cas."
