Despite Dean's teasing, Sam knows he isn't an idiot. He aces his classes in school and he's quick to spot a lie, which has always got on his dad's nerves. John's not as good at playing sober as he thinks he is.

So even if Dean likes to talk about "pussy" and goes around flirting with any girl who has a pulse, Sam knows why Dean only relaxes when Castiel's sleeping over at their house and why Dean comes back from Castiel's place practically wagging his tail.

Sam figures John's probably not coming back tonight. There hasn't been a knock or a phone call yet and he's already finished his supper, completed and packed away his homework, and made his lunch for school in the morning.

It isn't much of a surprise when he takes out the trash and finds John slumped outside in the bushes, snoring away quite happily. It's a warm night, and it's not Sam's job to sober him up, so he dumps the trash quietly and leaves his dad asleep on the floor.

Sam locks the doors and windows, pours himself a glass of water and heads upstairs, stalling when he hears a groan. It comes from his dad's room but obviously isn't John, and besides, it's not an unhappy groan either; another pleased groan escapes, shortly followed by a soft thud and Dean's voice whispering "Hush!".

Sam knows he isn't allowed in John's room, but neither is Dean, and the door is wide open when he approaches.

"Dean, is that -"

"It's not dad, don't worry," Dean says, adding, "You can come in, Sam."

Sam walks in and blushes bright red; Dean is on top of Castiel, and even if it looks nothing like porn, they're definitely having sex. Or were, anyway, before he interrupted. Dean grins at him affectionately, Castiel running a hand through his own sweat-curled hair and smiling too. It's a little weird to see Castiel smiling, he's usually the solemn sort.

"Dad's staying out again, huh?"

"Yeah," Sam says, putting down his glass of water and sitting down in grandpa's old rocking chair. Technically it's too big for him but that makes it more comfortable to curl up on, and he isn't as worried about his height as he could be - Dean hit his growth spurt pretty late too.

Dean turns his attention back to Castiel, kissing him on the forehead, the nose, and the lips, before rolling his hips. Castiel arches underneath him, moaning quietly, and Sam feels himself growing hard at the sight. Sam's not especially interested in his peers, but he's started getting crushes on other guys and girls. He loves watching Resident Evil because even if the movie's not that good, he's got a thing for almost everyone in it; he pretends he likes them for the gore, just to avoid further teasing from Dean.

He's definitely got a crush on Castiel, but Castiel is completely and totally in love with Dean, and about five years older than Sam anyway. Technically that makes the crush creepy, but Sam doesn't care; he knows five years is creepy now, but in another decade the age difference won't matter anymore. Assuming he still has a crush on Castiel at that point, anyway.

Dean likes to mock him because when they first met, Sam shook Castiel's hand. He wasn't thinking, he just wanted to touch Castiel and they weren't familiar enough to hug. Castiel had obliged, not seeming to register what Sam was doing as strange, and Sam had fallen just a little bit more in love with him for it.

"You having fun watching, Sam?" Dean says, and Castiel frowns up at him before leaning up, whispering something in Dean's ear that Sam can't make out. "Sure," Dean replies to whatever Castiel said or asked, lifting one of Castiel's legs up over his shoulder. The change of angle lets Sam see exactly what they're doing, the slide of Dean's cock in and out of Castiel's tight hole, and even as Sam's cheeks start burning and his cock hardens completely, he thinks for a moment that he's proud of Dean for using a condom.

It's a stupid thought but it's there, and Dean looks over, visibly pleased with himself and increasingly breathless. "It's hot, isn't it? Anyone ever tell you how to fuck a guy?" Sam shakes his head, and before he can add that he has watched porn before, Dean seems to read his mind. "Figures. It's not just spit and a finger, y'know," Dean says, before pulling out of Castiel who turns over and kneels, bracing himself with his hands on the headboard.

"It's easier for me," Castiel says, "I'd used toys before Dean."

"Still do, sometimes," Dean says, kissing the hollow of Castiel's back lightly before lubing up his fingers and pumping a little extra lube into the crack of Castiel's ass. "You won't need as much lube with toys, Sam. You'll still need it, but they're usually waterproof, so you don't have to keep adding more." He spreads Castiel's ass wide with his hands, making Castiel's hole easier for Sam to see before he slides two fingers inside. "Two fingers is fine for Cas, but you can just wing that. Find out what the guy likes, same as you would a chick." His fingers twist and probe, Castiel occasionally grunting when Dean does something he likes with them, before Castiel reaches back with one hand and grips Dean's cock, guiding it inside.

It almost glides in, and Sam wonders if it'll be that easy for him some day.

Castiel takes his hands off the headboard and sits back into Dean's lap so that he's riding him; the view's not as good this way, but it makes it easier for Castiel to turn his head and kiss Dean sloppily.

Sam takes it as a hint that he should leave, climbs out of the rocking chair awkwardly with his erection hanging heavily in his trousers, when Castiel clears his throat. He isn't kissing Dean anymore, his eyes on Sam again, but his expression is kind despite the throat-clearing.

"Come here," Castiel orders, and Sam can't really believe that Castiel is saying that. The fact he got to see Castiel naked, that he got to see Castiel fucked, that's more than enough good luck for a lifetime, surely? "Let me help with that,"

Castiel holds out a hand, draws Sam down to sit on the bed next to him, and presses a kiss to Sam's cheek. Castiel's fingers fumble with Sam's zipper, and Sam quickly assists by pulling his trousers off; they still slide off his hips without being fastened if he hasn't got a belt on, Dean's hand-me-down's several sizes too big for him but all they can afford.

Castiel's hand wraps around Sam's cock and starts tugging, and it's so, so much better than doing it himself, so good with this view and this smell and the fact that Castiel really, really knows what he's doing.

Sam doesn't last long at all, coming prematurely, and Castiel gives him another kiss before taking his hand back from Sam's cock to wrap around his own.

Sam's not erect anymore but he has to look; it's his come sliding up and down Castiel's erection, and although he's seen himself come - even seen it in a mirror, he's the curious type - it's completely different to watch Castiel orgasm. Castiel shudders and fucks himself back onto Dean's cock and up into his hand, bucking hard, almost silent despite the groans he'd been letting out earlier in the night.

Dean isn't silent, but he moves a lot less, just rolls his hips against Castiel's a few times before frowning and pulling out, taking care of the condom quickly. It disappears into the trash can by the bed along with the tissues he uses to clean them all up with; doesn't matter if John heads to bed later, taking the trash out has always been their job, not their dad's.

Dean rests against Castiel for a moment, kissing his shoulder a few times, before patting him on the ass and getting up, helping Sam up as well and gathering all their clothes together in a bundle. "See you in the morning, Sammy," Dean says, smirking and ruffling Sam's hair before heading out, dumping their clothes in the washing basket on the way to his own room. Castiel lingers a moment longer, gives Sam a quick hug and a kiss on the head before following Dean, no limp in his step as he catches up. Sam's a little surprised by that, but Dean did use a lot of lube, so maybe that makes sense.

Sam washes up and brushes his teeth, changes into his pyjamas and gets into bed, hears quiet muttering from Dean's room, but it's all the affectionate sort. He wonders how much of it is about him.

He falls asleep smiling.
