Author’s Note: Written for destial as pinch-hit for spn_j2_xmas. She wanted “a threesome fic with Sam and Dean and Cas where it's about Cas at first and the brothers are trying to avoid each other as much as possible until Cas talks them into kissing and then more”.

Dean wasn’t so sure just which of them had actually initiated this, but when he found himself naked on a king sized bed with an angel and his brother, somehow it didn’t seem to matter anymore.

It had all started with Castiel discovering porn though and his utter confusion and helplessness just triggered something in them. When Cas had whimpered in obvious discomfort at his boner one too many times, Sam and Dean had both offered to help him out. Simultaneously. But they hadn’t meant together. So when Castiel replied with a grateful “Thank you, that would be… kind,” they just looked at each other in confusion.

“Wait. So who do you want to help you out here?” Sam was first to ask.

Castiel tilted his head to the side. “Oh. I thought you would…” He bit his lip. “I don’t think I require a whore.”

Dean almost choked on his beer. “I guess that excludes you, Sammy,” he stated with a grin.

“Look who’s talking.” Sam raised his eyebrow. “If anyone, he was talking about you.”

“Bite me, bitch,” Dean snarked back, then he focused back on Castiel. “No, really, Cas. Which one of us do you want?” Dean’s voice hitched on the word ‘want’ and he quickly added, “To help you out.”

”I have to choose?” Castiel frowned.

“Uhm,” Sam smiled, obviously flustered. His eyes flicked back and forth between the angel and his brother. “That’s usually how it works.”

“Oh.” Castiel just stared at them. “But you both offered.”

“Yeah, but…” Sam looked at Dean, who shrugged and then avoided his gaze, looking down at the ground instead. And Sam could have sworn he saw a blush creep over his cheeks. Oh. Oh! “We’ll need a bigger bed.”

Which was how they found themselves in a different motel room, on the bed, only still glad in their boxer briefs, awkwardly avoiding each other, both of the Winchesters focusing all their attention on the angel. Some few stolen glances and accidental touches aside.

It wasn’t that they’d never seen each other naked. Hell, back when they were teenagers, hormones raging high, cramped up in a room together, sometimes even in one bed, they’d jerked each other off. But that was normal. That’s what boys did. It had stopped when Sam had brought over his first girl. Dean didn’t crawl into his bed anymore after that and Sam never dared to ask.

But that was a long time ago.

“Can you show me? Show me how to kiss?” Castiel asked, once they’d gotten on the bed and started touching. They were going slow, not wanting to freak out Cas.

“Of course.” Dean smiled, touching his cheek. “C’mere.”

“No,” Castiel turned his head away. “Show me on Sam. I want to see how it looks. I want to do it right.”

“Cas, I don’t really think you can do it wrong.” Dean sounded amused. “Especially not with us.”

“No, I need to observe.” Castiel refused to let Dean too close, seeming spooked.

“Alright. Fine,” Dean sighed. “You’d think with all the porn you watch…”

“There’s not a lot of kissing in porn,” Sam remarked with a shrug, although he didn’t make any move towards Dean.

“You would know.” Dean tried his best to avoid looking at Sam’s lips.

“No, you wou… ah, you know what? Screw this.” Sam leaned over, placing both hands on Dean’s face to keep him still and then kissed him. Just a peck at first, but he didn’t move away until Dean closed his eyes, hands coming up to tangle in Sam’s hair when he responded to the kiss, deepening it. It went from sweet to hot and heavy in seconds and soon they only broke it off when a whimper from Cas reminded them that he was still on the bed with them.

Castiel’s face was right next to theirs, watching up close, but instead of giving him another lecture on personal space - which might have been really stupid right now - Dean leaned over to kiss him next. Castiel was wary at first, but he was a fast learner and soon taking control of the kiss.

As soon as Dean pulled away to breathe, something Castiel apparently didn’t need to do, Sam took over, one hand mussing up Castiel’s hair, the other resting on Dean’s chest. Castiel was the one to break the kiss this time, and he pushed Sam and Dean’s heads together next, until the brothers were kissing again.

“You really like to watch, huh?” Dean asked breathlessly the next time he came up for air.

“Is that a bad thing?” Castiel replied, sounding unsure.

“No, it’s not,” Sam answered, mouthing along Dean’s chin and then trailing a path down Dean’s throat. In all their years of touching, they’d never actually kissed. Now Sam found it hard to dislocate his lips from Dean’s skin even for a second. “Tell him, Dean.”

“It’s not,” Dean parroted, before kissing Castiel’s doubts away, Sam trapped between them. “But we’re here so you can do more than watch.”

Cas nodded. “I know.”

“Do you?” Dean raised his eyebrow and grabbed a fistful of Sam’s hair, pulling him back. “Come on, Sammy. We’re here for Cas.”

“Lemme,” Sam protested, trying to get back to the hickey he had been working on, but when Dean tightened his grip, he came back down. “Yes.” He bit his lip, eyeing Dean’s throat guiltily. This wasn’t supposed to have happened. He shuffled away from Dean and placed a hand on Castiel’s chest instead, pushing the angel back down on the bed.

“Tell us what you like, Cas,” Dean commanded, lying down on Castiel’s other side and reaching out to flick one of his nipples. “Tell us what feels good.”

“And say if you want us to stop,” Sam added as an afterthought before he latched onto Castiel’s other nipple, worrying it between his teeth.

Castiel’s hips bucked up. “Oh!” He threw back his head, momentarily lost in the sensations.

“That good?” Dean asked, stroking Castiel’s hair. “You can tell us.” He didn’t give him any chance to reply though and instead stole another kiss from the angel’s lips.

Meanwhile, Sam was kissing his way down Castiel’s body, holding him down with his arm slung over his hips. The second he was mouthing at Castiel’s cock through his briefs, Castiel came with a loud yell.

Dean looked down to meet Sam’s surprised face, both of them fighting hard to bite back a chuckle. Castiel had his eyes closed, looking blissed out. “Is it always like this?” he asked.

“No.” Dean kissed the side of his mouth softly. “It’ll be a lot better next time.”

Castiel opened his eyes, blinking rapidly. “I, but… this…” He gestured helplessly.

“Trust me,” Dean reassured him, nuzzling his cheek.

“Mmm,” Castiel hummed. He reached for Sam, who came back up, amused expression on his face. “Okay.” Castiel took a deep breath. “Continue.”

“So we’re your own private pay TV today, that it?” Dean joked.

“I have to pay?” Cas was confused again.

“Yes,” Dean confirmed. “But don’t worry. We’ll give you credit and we just have to keep doing this until we’re even.” It was out before he could even think about it and he shot a careful glance over at Sam. Sam held his gaze for a moment, then he nodded. Yeah. This would not be a one time thing.

“I want to learn.” Castiel started. “Sam, blow him.” Both Winchesters just stared at him. “Did I not use the right word?” Castiel frowned. “The pizza man…”

“No,” Sam cut him off. “It’s okay, Cas.” He was looking at Dean as he said it. “Anything you want.”

“Yes,” Dean swallowed, slight tremor in his voice. “If you want it, Cas.”

They were both using the angel as an excuse to still be able to face each other once the night was over, and they both knew it. But it worked. Dean rolled over on his back, trying to get comfortable, but it was hard when both Sam and Castiel crawled down on either side of his hips.

“Do you, uh, want pointers?” Sam asked, worrying his lip.

“I just want to watch.” Castiel leaned closer, inspecting the bulge in Dean’s black briefs.

Even though they hadn’t even touched him yet, Dean was clenching his fists into the sheets, breathing hard. The anticipation was killing him. As was the view. His brother and his angel both kneeling this close to his dick. “Fuck.”

“Patience, Dean.” Sam smirked up at him, evil twinkle in his eyes. “Remember, this is not about you. It’s about teaching Castiel all my tricks.”

Dean could only whimper in return, but Sam chose mercy and at least rid him of the offending garment. When he was exposed to their gaze, Sam licked a long stripe up his length, then swirled his tongue around the pre-cum pooling at his head. Before he could swallow, Sam pulled Castiel in for a kiss, sharing the taste.

Eyes closed, Castiel savored it on his tongue and Dean was ready to explode just as fast as Castiel, right here and now. Only years of training and coming up with the right images to immediately cool down kept him from embarrassing himself.

It only got worse from then on, because as it turned out, Sam knew a lot of tricks. Dean didn’t even want to know where he learned half of them. But it was torture, pure and simple. By the time he got Castiel to participate again and they were both licking up his cock, Dean was a writhing mess.

Sam and Cas shared an open mouthed kiss right over him, both of their tongues touching him, gliding slick and smooth across the sensitive head and that was it. With a quick warning on his lips, Dean came, his come splattering both of their faces. When he came to again, Sam and Castiel were licking each other clean and for a moment, Dean wondered if Gabriel was still alive, because no way was this just happening.

Sam was whispering something into Castiel’s ear and Cas nodded thoughtfully. Then he reached up, holding out two fingers for Dean. “Suck,” he tried to command, but it came out more as a question.

Dean assumed Sammy was next, so he got Castiel’s digits as wet as he could, tracing patterns over them with his tongue. Cas mouth fell open and he was staring at Dean, who winked at him in return and then released the fingers with a pop.

“Fuck, Dean.” Sam’s voice was almost a growl. “Do you have any idea how sexy you are?”

A rush of heat went through his body at the praise, and he immediately felt guilty. Sammy was not supposed to say shit like that. Dean was not supposed to love hearing it. “Shut u...” His voice broke of when Castiel pushed both of his fingers into his ass. “Ngh.”

“Jesus.” Sam took a hold of Castiel’s wrist, pulling him back. “Go easy on him.”

“But you said…” Castiel looked stricken.

“S’okay.” Dean felt the need to reassure him. “I can take it.”

Another growl from Sam. “Do not. Do not say stuff like that, Dean. Just don’t.”

“Am I doing it wrong?” Cas’ fingers hovered in mid-air.

“No,” Sam advised, taking a hold of one of Dean’s legs and bending it before pushing it back up, exposing more of Dean’s backside to their gazes. “But start with just one. Then we’ll go from there.”

Dean wasn’t so sure how he should feel about being the practise test dummy again, but he couldn’t deny getting off on Sam manhandling him like that, on being used by both his brother and Castiel. Of course, he’d never admit to that and he’d properly bitch at them… tomorrow. Because for now, he couldn’t do anything but babble and keen while Sam and Castiel scissored him open.

“Sam, will you fuck him?” Castiel asked wide-eyed.

It took Sam a full minute before he was able to reply. “Don’t you want to?”

“No.” Castiel shook his head. “Yes. But next time. After I’ve watched you do it.”

Dean knew this was probably his cue to say something, to get in a few protests and lay some claims of his own, but he found himself completely unable to comprehend what was happening here. He only knew he was going to get fucked, and at this point, he didn’t care who was gonna do it anymore. Hell, they could both go ahead. And it was probably really good that he couldn’t suggest that either. They might have taken him up on it.

He was rolled over and pulled up to his knees then and he could feel the head of Sam’s cock pressing against his entrance. And that’s when it suddenly hit him, what was about to happen. Dean made a sound from somewhere deep in his throat and Sam stilled.

“Dean?” He asked, stroking up and down his back. “You okay?”

Dean nodded.

“You okay with this?” Sam pressed on, suddenly sounding a lot like Castiel. Unsure, afraid.

Dean pushed himself up, clearing his throat to make sure his voice would work. “Fucking get on with it already before I think you’re the virgin here, Sammy.”

“Jerk,” Sam smiled. “I’ll show you virgin.” He pushed forward, entering Dean on one long thrust. He gave him some time to adjust before he carefully pulled back out.

He set up a slow rhythm, probably for Castiel’s sake and Dean could just imagine him hovering up close, enjoying the show. He turned his head to glance back, then quickly turned around again. This was too much. His cock had hardened again a while ago and was now staining the sheets with his pre-cum as it was dragged along them.

“You’ve seen enough?” Sam asked. “Because I think you’d enjoy the view from the other side of the bed a little better.”

“But…” Castiel started to protest.

“Dean can suck you while you watch.” Sam fisted a hand in Dean’s short spikes and pulled him up to get his attention. “Won’t you, Dean?”

Nobody waited for him to reply, but Castiel took Sam’s cue, sitting down in front of Dean. Dean looked up at Cas, going for an easy smile, but Sam chose that moment to speed up his thrusts and he gave up, just buried his face in Castiel’s lap and tried to use the few brain cells he had left to show Cas a good time.

And Castiel was fascinated. He kept showering Dean with praise, his fingers touching Dean’s lips, tracing them where they were joined and then wandering to Dean’s cheeks, his chin and nose, caressing his eyelids before coming back to his lips.

In all his life, Dean had never felt as worshipped as he felt right now. Yes, he was basically the one getting fucked here, but there was just something to their touches. Even Sam, who was madly pounding away at this point, still took care to reach around and jack Dean’s cock.

When he came this time, he was flying on such a high that it lasted for minutes. It was almost like a dream to feel Sam empty inside him before he swallowed Castiel’s come. He couldn’t even open his eyes anymore, he just slumped against the sheets when the both of them moved away.

He only had seconds to feel the cold creep in before he was spooned by Sam from behind and Castiel was cuddling up into his arms. Dean nuzzled his face against the angel and breathed him in, reaching back to grasp Sam’s hand and make him wrap his arm around both him and Castiel before interlacing their fingers. And then he passed out.

Much later that night, Castiel finally had the heart to disentangle himself from the Winchester brothers. He knew he couldn’t stay any longer or he’d never be able to leave again. He was grateful to the both of them and he knew he would definitely be back to repeat the experience. Maybe next time he could try what he’d learned from the plumber.

But for now he pulled the sheets up around them, watching Sam curl up tighter around Dean, keeping him safe even in sleep. He smiled. Yes, he’d benefited from tonight as well, but more importantly he’d helped his friends reconnect. He didn’t understand why they hadn’t touched each other intimately before tonight, but he’d observed enough humans to know they both wanted to, and they’d be happier now that they could.

Castiel smiled to himself. One last, long look and then he’d be gone.
