Rating: NC17
Any warnings: current canon but no real spoilers

“I meant it,” Cas says as he follows them into the bunker’s kitchen.

Dean already has a couple of beers in his hand; he transfers one to Sam without even looking, already open.

“Meant what?”

Castiel shakes his head no when Dean nods at the fridge, where more beer waits. It’s been a stressful day.

“What I said. About loving you.”

Dean makes a face. He’s turned away from Cas, but Sam can see the discomfort. It’s one thing to make an emotional confession when you’re dying, another in the relative safety of the bunker after the bad guy is dead and nobody’s in imminent danger.

Sam doesn’t mind, though. It’s one of the things he likes about Cas, the relative naivete with which he makes pronouncements like this. As naïve as an ancient being whose knowledge dwarfs anything the Winchesters – or even the blustering British Men of Letters – will ever acquire can be.

“Yeah Cas, we know,” he says, hoping to reassure.

“I’m gonna turn in.”

Dean’s already heading for the doorway, probably embarrassed about his own display of emotion earlier, when they all thought Cas was a goner. Sam knows he meant it though. Dean is fond of Castiel too, he just doesn’t like to admit it.

Sam turns to follow his brother; that’s the story of his life sometimes, but Sam doesn’t mind that either. Recently it’s been the other way around more often than not. It doesn’t really matter to them who’s in front as long as they’re in step.

“Wait.”

They both stop. It’s not like Castiel to make a demand, but there’s urgency in his voice.

“Let me explain.”

Dean spins around on his heel, fixes Cas with a put-upon look. Sam stops too, his shoulder knocking against his brother’s where they’ve paused in the doorway.

“You don’t need to explain,” Dean says with exaggerated patience. “You were dying, people say things when they’re dying. It’s okay.”

Castiel shakes his head. His eyes are midnight blue, and he’s biting his chapped lips, and Sam suddenly has no idea what Cas is going to say.

“I do need to explain,” he insists, “It’s important to me that you understand. In case I die the next time. This is…it’s a brand new start. For us.”

“There won’t be a next…” Dean begins, but Cas talks right over him.

“I love you – I love you both.”

“Yeah, you said that, Cas…”

“I love you the way you love each other.”

That shuts Dean up right away. Sam can feel him tense, the warmth of his brother’s shoulder that was leaning into him suddenly pull away as Dean straightens. Cas doesn’t know what he’s saying, of course, but it still makes them both startle.

Dean’s voice is a little too even when he answers.

“Like a brother, yeah Cas, we know.”

Castiel shakes his head slowly.

“The way you love each other,” he repeats, and Sam’s stomach does a back flip.

“I don’t know what you’re…” Dean begins, and Cas takes a step toward them, interrupts him again.

“I’ve watched you,” he admits, and Dean is shaking his head now, staring at Cas like he can’t believe this is actually happening.

“I know I shouldn’t have, but I heard noises, here, in the kitchen. It was late, I thought you were asleep.”

“No,” Dean insists, but it’s a whisper, barely any voice to it at all. He’s still shaking his head.

Castiel takes another step forward, and Dean sways suddenly, almost trips backwards trying to back away. He bumps right into Sam behind him, then flinches. Without thinking, Sam puts a hand on his waist to steady him.

“I’ve watched you,” Cas continues, “When you’re on your knees, Sam. What you do to him.”

“For fucksakes Cas, shut the hell up,” Dean snaps, but Cas keeps going. He takes another step, a look of determination on his face. “The way he bites his lip, like it’s killing him. The way his hands always end up tangled in your hair.”

“Don’t,” Dean pleads, “Don’t. You can’t.” He staggers backwards, like his legs won’t hold him up anymore, and Sam wraps his arm around his brother’s chest.

There’s no stopping the angel, though. His blue eyes are dark, lit with a fire Sam has never seen in him before. His words are meant for Sam, but he’s looking at Dean.

“He’s so gentle, Sam. Caressing you. And then his fingers grow less gentle, winding tighter and tighter, until he’s pulling you where he wants you, both of you straining…”

“Jesuschrist Cas, shut up, just shut up!”

Dean’s yelling now, and that makes Cas stop walking but not stop talking. He looks right at Sam.

“You are his then.”

“Ohgod,” Dean groans, but Castiel is still looking at Sam.

“And he is yours.”

“Fuck,” Dean says. He has one hand on Sam’s arm where it’s wrapped around him, hanging on like it will anchor him. “You weren’t supposed to know.”

Dean has never been as okay with this as Sam is. Sam stopped caring what other people might think if they knew a long time ago. There was a lot that other people didn’t know, from watching your brother be ripped apart by hell hounds to stopping the apocalypse, and he just couldn’t work up much righteous indignation about a little fraternal incest.

“Sorry, Cas,” Sam offers anyway, because it seems like the right thing to do. Incest is probably a bit more traumatic for an angel.

There’s a small, soft smile on Castiel’s face at that. “Don’t be, Sam. I just want to know what it feels like,” he says with something like awe. “To be on my knees for him.”

Sam can feel the shiver that goes through Dean at that. He thinks maybe he should be jealous, but his dick is already letting him know that’s not how he’s feeling at all.

“I know what it is to kneel,” Cas continues. “But not like that.”

Sam makes the decision right then. He fixes Cas with his best sexy smirk, the one that always makes Dean surreptitiously brush his hand over his crotch like he needs to push his dick down.

“He’s trembling, Cas. See what your words are doing to him?”

Dean makes a hurt little noise at that, his fingers digging into Sam’s forearm. His voice is low and dangerous when he speaks.

“What the fuck are you doing, Sam?”

“Am I reading you wrong? Because you say the word and this ends right now.”

Castiel nods instantly. “Of course. I didn’t mean – I would never.”

The angel’s blushing now, looking at the floor. “I’m sorry, Sam, Dean. I know it’s different between the two of you, and I would never…”

“It’s okay,” Dean interrupts, and Sam can feel him square his shoulders where he’s still pressed up against Sam’s chest. “It’s okay, Cas, it’s just – it’s a surprise. A big surprise.”

“But you want it, right?” Sam whispers it against the back of Dean’s neck, feels his brother shudder.

There’s a long pause while everyone waits. Finally Dean nods, and Cas actually licks his lips as he takes a step closer. Three more steps and he drops to his knees, looks up at the Winchesters with hungry eyes.

“Go ahead,” Sam says, and watches Castiel’s fingers fumble at Dean’s belt, clumsy with eagerness. The snick of Dean’s zipper is loud in the silence of the bunker, his harsh breaths as Cas slips his hand inside and caresses him even louder.

The angel is a quick study. Sam wonders how many times he’s watched them. He strokes Dean through his shorts until his dick is hard enough beneath the cotton to jut obscenely from his opened jeans, just like Sam does. Then he bends and kisses the swell of it, drawing a stifled moan from Dean because fuck, that’s exactly how Sam does it too, can never resist putting his lips there before it’s even out, worship and affection rolled into one.

Cas smiles, pleased that he’s drawn the same reaction from Dean that Sam does, carefully pushing Dean’s jeans lower on his hips, then sliding his fingers beneath the elastic of his shorts to slip those slowly down too until Dean’s dick is freed. He’s so hard it slaps against his stomach, and both Winchesters can’t quite stifle a groan.

Castiel shuffles forward on his knees, hands on Dean’s slim hips as he leans in and puts his mouth on Dean’s belly, nuzzling the treasure trail beneath his navel, teasing himself and making pleased little murmurs that Sam doesn’t think he’s aware of. He kisses the indent of Dean’s hip, pokes out his pink tongue and follows the groove, leaving Dean gasping.

“Sam,” Dean breathes out, a gruff whisper, and Sam bends to kiss the exposed skin of Dean’s neck in answer. Dean cranes his head to the side so Sam can have more of him, and Sam takes the invitation, nipping at an earlobe, biting at the tender flesh under his jaw. Dean groans, fingers spasming around Sam’s forearm. Sam slides his other arm around his brother too, pushes up his shirt to thumb at a nipple.

When Sam looks down, Castiel is looking up, his eyes following the movement of Sam’s fingers as he pinches and pulls. Dean likes it rough. Cas probably already knows that though.

Cas makes a noise then, a punched out groan like one of them has hit him, and he goes down on Dean in a frantic lunge, too deep too fast and he chokes and coughs. Dean echoes the sound, throwing his head back as Castiel tries again, determined to take more of Dean’s length this time, and Sam thinks he maybe should mention it took him a long time to be able to take as much as he can now and it’s still not all.

It hardly matters though, Dean’s close already, thighs trembling and heart racing triple time where Sam’s hand is pressed to his chest. Castiel is working him diligently, one hand pumping what his mouth can’t manage and the other clumsy on his balls, not daring to be as rough as Dean likes but it’s enough.

“Cas, fuck, god I’m gonna – I –“

If anything, Cas redoubles his efforts, and Sam gets a ring side seat to watch Dean come down Castiel’s throat, the muscles in his stomach rippling as he does, and god, that’s hot.

“Stop, stop,” Dean says eventually, voice hoarse as he pushes Cas gently away.

Cas lets him go reluctantly. The angel looks completely debauched, come in his hair and his mouth red and wrecked, his cheeks damp. There’s a dark spot on the front of his pants that says he enjoyed every second of what just happened.

“You okay, Cas?”

Dean always asks, even after a decade of them doing this.

“You need..” He gestures to Castiel’s pants.

Castiel nods and clears his throat. “I am fine. Thank you. Thank you for that.”

Dean huffs a laugh. “I think that’s my line.”

Cas rises to his feet as gracefully as a cat, no evidence of sore knees. Sam is envious.

“Your turn, Sammy?” Dean asks playfully, and Sam jumps when there’s suddenly a hand on his dick.

“Dean!”

Dean squeezes him, and a shock of pleasure jolts through Sam. He hadn’t even realized he was that turned on.

“I could…” Cas offers, but Dean shakes his head.

“Not sure I’m quite as good at sharing as Sammy is.”

Cas nods, his expression serious.

“At least not yet.”

The angel brightens at that, beaming at them both. “If you desire another time, I’ll be happy to participate. Like I said, I love you. Both.”

Dean nods, but he’s already shoving Sam backwards, motioning toward the bedrooms. His jeans are still undone and his cheeks are still flushed and Sam is suddenly very on board with that.

“Goodnight Sam,” Cas calls from the kitchen. “Goodnight Dean.”

‘Our lives are weird, man,” Sam says as Dean shuts the door behind them.

Dean’s on his knees already, fingers as nimble on Sam’s fly as they are handling a gun. The thought makes Sam even harder.

“Maybe next time when Cas wants to blow you, I’ll have my dick inside you,” Sam says, pitching his voice low and making his words dirty because he knows what that will do to his brother. “Make sure you don’t forget who you belong to.”

Dean doesn’t answer. But he has a very good reason.
