For the kinkfic thing. power imbalance and breeding for uh. Charbeej plz. :-D

(prompts now closed) (Okay so this is a lot of breeding kink, a little power imbalance, and though it is charbeej on the page, both beejhawk and charbeejhawk wiggled their way into it, and I really hope that's okay!! It's also 6.4k I'm very sorry—)

"Aaaaaaall right, Winchester," BJ trills as he sweeps into the Swamp and sets the lock behind him. Now that necessary arrangements have been made for privacy, he's got a certain spring in his step, a song in both his heart and his dick. "Here we go. You ready?"

Charles looks up suspiciously from his desk where he's cross-referencing something in a book to the notes he's taking. "I haven't the faintest idea what you mean."

BJ drops the tent flaps in one quick rush, then strides over to slap his hands on Charles's shoulders. "That's never stopped you from offering your opinion before, so why start now?" When Charles tries to look back at his work, BJ cradles his cheek and steers him right back around. "You can do that later."

"For heaven's sake." Along with a particularly overexaggerated roll of his eyes, Charles's lips rise up in a snarl that does nothing more than bring tingles of anticipation down BJ's spine. "Hunnicutt, are you sure you haven't taken a tumble recently? Banged your forehead on something? It's quite a large target." He makes a show of shrewdly considering it, all the while ignoring how BJ's beginning to smirk. "Can't imagine any other reason why you appear to be mistaking me with Pierce."

"I'm not making a mistake," BJ murmurs in a low, sweetly rotten tone.

"He's the one you, ah, sully around with, you know." Charles goes on as though he didn't hear BJ say a word. "Little whimsical pet practically slobbering for the chance to do your bidding."

As BJ tightens his grip around Charles's soft jaw until he feels the bones stabbing into his fingertips, Charles finally goes silent and flicks his gaze back up. "Charles," BJ breathes. "Put your pen down. And take your pants off."

Clack. The pen's rolling across the desk before BJ even realizes that Charles opened his hand. They share a long, silent stare where he gets to watch how Charles's brow furrows, the quick analyses occurring behind his eyes.

Honestly, BJ gets it. He wasn't wrong, bringing up Hawkeye like that. Usually BJ and Hawk are rolling around together in a cot, trying to get a rise out of Charles across the room, and in the few circumstances where they've actually seen a response—the heat on the back of his neck or the faint wiggling of his restless leg—they've slipped off the mattress like sirens, finding their way to him, meeting his sharp-edged banter with teasing words of their own. It's just an extension of the rhythm they've all ended up in, the games they like to play. Inevitably they all end with Hawkeye as a ruined mess of some kind while BJ and Charles study each other, still panting as they recover from their own release.

This is the way of things nowadays. Since BJ and Hawk are finally over the first nervous hurdles of trying not to fuck things up, BJ gets to take what he wants from an extremely enthusiastic Hawkeye practically whenever he chooses to do so. Charles, meanwhile, has to be all but forcibly dragged in on a casual basis regardless of the fact that he so clearly desires their time. There are times when BJ doesn't think it's even the sex that Charles craves, though the man's certainly never complained about an orgasm. Maybe it's the easy possession. Hawk will drop into BJ's lap, or BJ will pet through Hawk's hair and scratch his scalp during a normal conversation, or Hawk will mold himself around BJ's back and grope him with a hungry groan without so much as a hello. They're open to each other. They're always around to offer support, love, comfort, and passion. Charles seems to need to wait until he's about to burst before he so much as asks if one of them will have a serious conversation with him.

BJ doesn't know if he'd call it jealousy. Just a longing that appears to humiliate Charles. No wonder he needs to be surrounded and caught before he'll let all of his muscles unclench.

Charles finally takes a deep breath. "Should I presume Pierce will be arriving shortly?"

"No," BJ murmurs. "I don't see you going for your pants."

"I don't see a reason why I should," Charles counters.

"How about because I'm gonna fuck you?" BJ leans close and bumps their noses together. "Or how about because I said so?"

No matter what Charles tries to hide from them, he can't conceal that flush of his. His clean, pure, pretty blue blood does so love to betray him in moments like this.

Despite himself, BJ feels heat rush straight into his cock.

"Y'know, I've noticed something about you," BJ murmurs. He shrugs on a warmer tone like a robe, watches how Charles instantly goes for his belt. "You're really not a joiner, huh?"

"Difficult to find one's way into anything when there's not an inch of room," Charles counters. He doesn't sound hurt, exactly, or even sullen, but there's an edge in his voice all the same, and BJ files it away.

BJ shrugs, pursing his lips. "I mean, you could ask for somebody to move over, couldn't you?"

Charles finally breaks free from his grasp. He pushes his chair back with a loud scrape as he takes care of his trousers, then folds them perfectly with not a wrinkle to be seen. With his attention so focused on the task, he either doesn't think to or chooses not to reply.

"I don't know. It's just interesting. Sometimes I'll look over and you're holding yourself back by a thread." BJ chuckles like this is a meaningless conversation. Charles doesn't have to see the keen, smug expression he wants to wear. Not yet. "Like last week, y'know? Hawk and I are in my bunk. I've practically got his ankles behind his ears. He's ready to cry, he wants it so bad. Begging for it. Begging to be bred." Just like that, BJ flicks his gaze up, watches how Charles freezes. Yeah. There you are. BJ finds Charles's hip with one broad hand. As he slips his fingertips under the hem of his shirt, Charles drapes his trousers over the back of his desk chair, then grabs on tightly. "You don't have to be shy about it. I know you've got your thing. You need a son and all that, don't you?"

"I don't see why that's any of your business," Charles mutters, but unfortunately for him, he's starting to tap his foot rapidly on the ground.

"Aw, simmer down, Chuck." BJ moves into him, rests his chin on his shoulder, and lets his fingers continue to wander around to his front. "It's just some fun, yeah? Not that serious."

"Maybe not t—" Charles cuts off in a shiver as BJ shapes his palm right over his round belly. This is where it gets interesting. Hawkeye's easy by his own admission. He'll drop to his knees with little more than a look. But Charles turns his head, face so close that it's blurry, and speaks quite softly, one even tone. "Are you making a mockery of my duty?"

BJ chews on his bottom lip and considers the game here. "No," he finally says with a spreading smile. "C'mon, I wouldn't do that. I'm fetishizing it."

"Y— Excuse me?" Charles's brows shoot toward the sky. He gapes for a few moments before he scoffs. "Only you would take such a noble act as continuing one's bloodline and turn it into nothing but fodder for your perverse entertainment," he snaps.

Uh-huh. BJ takes in how red the apples of his cheeks are. "Not only me. Hawkeye too."

"Of course," he drawls, flicking his gaze away.

"So here's what I figure. You and me both know what kind of guy Hawkeye is." BJ considers further still. He could demean their bunkie, call him a slut—nine times out of ten, that gets Hawk dripping, so it's not like he'd be insulting him—but Hawkeye's not at the middle of this. The only thing he's doing is making sure nobody's gonna come bother the Swamp. No, right now he's just a segue, and one that BJ's happy to deploy. "So if there's a quiet little sector of your brain that gets turned on thinking about getting somebody in the family way, you already understand that all you've gotta do is walk across the tent and tell me to scooch, and I'll be happy to let you breed him. Joining of forces, right? With two of us at it, it's gotta take."

Charles inhales deeply, only just barely audible. He hasn't tried to move away. And when BJ begins thumbing a slow circle through the coarse hairs on his belly, all he does is breathe a touch faster.

"But yeah, no, you're right, you wouldn't do that. Not since the mumps. It stresses you out too much to think you might not be able to get the job done anymore."

"Hunnicutt, I'm warning you," Charles mutters.

When BJ rocks his hips forward, Charles freezes, fingers kneading the back of the chair. BJ grinds just the once more, simply making absolutely sure that Charles can feel how hard he is. That he knows this isn't a dig. Only a game. One that he's very enthusiastic about participating in.

He likes doing things like this, shifting into almost a variant of himself. BJ Hunnicutt—intensely devoted father, holding himself together by braided strings of hope that he'll make it home before Erin's childhood has passed him by—everyone knows who that is. But this is like shrugging on a coat, or perhaps shrugging it off instead. He can feel his voice getting a little more musical, a touch sharper, can find the sincere ache inside of himself and coax out its shadow. For him, it's a harmless perversion that lets him take a step backward when the walls are closing in. But he rather wonders if there's subversion that's about to rise from under his fingertips.

"Then I realized that it doesn't relax that stress at all, playing at getting Hawk pregnant." As he touches his lips to Charles's ear, he pulls him back so there's not a millimeter between them. "You'd rather somebody else do all the work of making sure the Winchester heir takes."

BJ can practically hear Charles's brain explode into a million simultaneous thoughts. He gets it. He knows a little something about shoving shit down so it can't even bleed through the cracks. There's something massive under all that noise that's aching to get out. BJ's just enough of a curious bastard to wonder what might happen if it does.

"Get these off too." BJ drags his hand down and tugs at the waistband of Charles's underwear. "Then lie in the bed."

He doesn't wait to see if Charles is going to argue or obey, just walks back to his side of the Swamp to unlock his truck and shove it open. He finds the tub of lubricant right away; as long as the trunk's locked, it's not as though he needs to hide it any more than that. In fact, he needs it easily accessible for those nights when Hawkeye has him ripping his own clothes off to have him as soon as possible. But BJ takes his time, moving items here and there, making noise, then stalling further still by unlacing his boots, acting as though his own blood's not boiling with a certain hunger of his own. It's tender with Hawk, playing this game. Charles is different.

Behind him, a cot creaks, and BJ takes a long, deep breath to steady himself. He snatches up the tub and impulsively snags a condom packet, practically slams the trunk shut, and stands before he kicks his boots off. When he turns back around, he drinks in the sight of Charles in his cot, under his blanket, up on his elbows so the impersonal fabric is at rest around his waist. His trousers may be neatly draped over the back of his chair, but both his boxers and, unrequested, his shirt are in a pile on the floor right where BJ had left him. He's waiting. Waiting for BJ. Wanting him to call the shots.

It's enough to make a man want to tip away from his logical mind, find himself somewhere feral instead.

BJ's made the particulars of how he inhabits his body into an art form. He shot up too tall too fast, filled out his shoulders before any of the other kids in his class. It was vital that he learn to move like water, fluid and flowing, never threatening. It softens him. But right now he thinks about some of the other jocks in his fraternity house, how they would cut through a room in such a way to have people scrambling to give them space. The tough guys. He centers his mind on it, and only then does he saunter toward Charles's cot. He doesn't have to look at Charles's face to know he's suddenly rougher at the edges, maybe even a little intimidating, but it's gratifying all the same, watching him takes in BJ from head to toe while the slight lift beneath the blanket becomes more and more prominent with each passing second.

BJ comes to a stop right by him, and as much as he wants to dive in headfirst, Hawkeye has goaded and begged for just enough things that BJ had never even conceptualized could arouse a person to a point where he speaks quietly all the same. "Is there anything you wanna talk about?"

Charles opens his mouth, closes it, then shifts his gaze to the back corner. "Hunnicutt, I-I realize this might strain you to the point of throwing out your back, but I would prefer..." He digs up fistfuls of his blanket. "You may say whatever it is that you'd like—as long as you don't laugh at me."

BJ notes it. He's not sure what exactly compels him to reach for one of Charles's hands, coax it to open, then lift it to his lips, but as BJ leaves a kiss on his knuckles, goosebumps lift all the way down his bunkie's bare arm. "Anything at all, huh?"

After one brief moment of thought, Charles nods.

He smiles. "Well. Lucky for you, I have a lot to say."

"Ahaha," Charles drawls out. "Will wonders never cease?" Unfortunately for him, his mockery nowadays is as sweet as a caress.

BJ's far better at reading the things Hawkeye craves without a lot of explanation, but though he has a good line of clues to follow here, he still takes his steps more carefully than he would through a minefield. He backs away, holds up the condom between two fingers, waits for Charles's eyes to focus on it, then tosses it carelessly behind his desk. Charles's punched-out, ragged huff shifts to a groan at the last possible moment and leaves a checkmark by the next item on BJ's mental list. He turns to hide his smirk as he snags the pillow from the spare cot. It's lumpy, which is why none of them have replaced their own pillow with it, but it'll serve a decent enough purpose tonight.

For a man who craves silence, Charles seems antsy now that BJ isn't talking. He shifts and wiggles, adjusting his weight, while BJ crosses back to his side, then glances along the blanket. He considers. Decides to pull it away himself rather than make a request. Charles's thick cock is slick at the tip, flushed all over, and it gently curves toward his belly while BJ shoves the rough cover into a pile at the foot of the cot.

"Lift your hips." Though BJ says the words as quietly as he can, they still sound as loud as a gunshot to him. They even make Charles flinch. But all the same, Charles obeys, and BJ tucks the pillow under them, then rests his hand on one of his thick thighs with a low hum. At first, he simply rubs as though to soothe him. But then he rises higher and higher with each pass until he's feeling the breadth of Charles's ample hips. It seems to settle in what he's doing just then, given how the cock near his hand twitches.

He can't make either of them wait anymore.

He leaves the tub on Charles's end table as he comes to his feet, then strips down as quickly as he can. Though he half-expects Charles to tease him for this too, he doesn't. Maybe he's just as relieved to see BJ overwhelmed by the need to fuck him. BJ keeps his eyes on Charles's face, catches how he stares at his arms, his stomach, and finally resting on his long, hard cock. Fascinated, BJ reaches high overhead, coming up on his tiptoes in a full-body stretch, and Charles whips his head around so quickly that he's shocked it doesn't fall off.

Somehow that kind of response is just as gratifying, flustering him like that. Usually it's Hawk who ends up in Charles's lap or on his knees for him while BJ sits behind, murmurs filth in his ear or coaxes Hawk to take him faster, deeper. He rarely gets his hands on Charles and he's never on display. Not unless Charles is watching them from his side of the room while they lose themselves in one another.

He needs to get started. It's not bragging to say that he's a lot to take. BJ pops open the tub so he can slather his fingers in lubricant, then gets to work.

For a couple of minutes, he's silent, studying how Charles's body responds—if he's moving too slowly, too quickly. There's a moment where Charles digs his nails into his own thighs and BJ thinks it might be time to start distracting him. "You're tight," he observes. "Don't usually do it this way around?"

"Don't usually do it," Charles corrects him in a rough voice. "Before you two, at least. You make it...rather difficult to resist."

"Mm. Any particular reason why not?" BJ thumbs over the back of one of his hands, silently coaxing him to loosen up.

"Well, it certainly wouldn't be appropriate to risk..."

As he trails off, BJ slowly smirks, focusing simply on how his fingers stretch him out little by little. It really does all come back to this, huh? The pressure to produce an heir, the pressure to make sure he doesn't produce the wrong one, the forced isolation such a thing causes. "But there were always other boys, right? C'mon, Charles, I went to an Ivy League too. I know how you prep school fellas are."

Charles's muscles flutter around his fingers, one moment clenching almost painfully tight, the next relaxing so suddenly that he sinks in to the next knuckle before he planned to. "Hunnicutt, this is yet another piece of information that I don't owe you." The however hovers in the air. BJ skims his gaze up and locks eyes with him while he pulls back, works in another finger. "Fo-ooooo-or the record..." The word warbles when BJ scissors his digits open, but he admirably avoids laughing at him, if he does say so himself. "...Mother and Father were...concerned about Honoria and me from the beginning. I should say we did not in-spiiire confidence—do you know how thick your fingers are?" Charles demands.

BJ tips his head to the side, not blinking. "Are you complaining?"

Charles wrinkles his nose, then flops back on his pillow and stares at the ceiling as he speaks in a rush. "I cannot say for sure regarding Honoria's own schooling, but I had reason to believe that my parents asked for the administration to keep a close watch on my relationships with my fellow students."

After a thoughtful moment, BJ nods. There are two paths he could take with this. One would coax Charles into a deeper vulnerability, maybe even open up an extremely strange heart-to-heart between two of the most unlikely men to experience such a thing. The other, though... BJ licks his lips. "Not much chance to experiment, then."

"Decidedly not," Charles murmurs.

The moment BJ rests his other hand on Charles's belly, he feels him stop breathing. "Dodged a bullet there too, then. Or a bun."

Charles doesn't reply. But he relaxes a little more, and BJ is confident that he's ready for him, experienced or not. He slips his fingers out slowly, and when Charles clenches around the emptiness, he fights not to push his cock inside of him right that instant.

BJ turns his attention to gathering just a touch more lube on his clean fingers so he can slick himself up, moving at a glacial pace, silently inviting Charles to watch. "Well. It's a good thing I'm here now, huh?" He drops his voice to that melodic tone with sharper edges. As he puts one knee between Charles's thighs, it lets him be far, far above him, casting a shadow from the nearest light. "Clever of you, really. You got all the way to the other side of the ocean where they don't have a clue what you're getting up to. Who you're getting up to it with. No one's watching, not tonight. There's just Hawkeye somewhere out there, keeping people entertained, making sure they won't come anywhere near the Swamp."

Charles clears his throat. "I suppose that is rather fortuitous, isn't it?" he asks unsteadily, still not looking away from how BJ's teasing himself.

"It really is. That's the beauty of it, huh?" BJ asks. "You don't have to worry about if these work anymore." He palms Charles's balls, gently massaging them just to watch how he shudders and fights to hold back his sounds. "'Cuz you're not gonna be the one knocking somebody up. At the end of the day, you're still a Winchester. And that means you're fucking great breeding stock."

There it is. Charles's eyes widen so far, they've gotta hurt. It's rare that he lets himself be this visibly stunned, especially in front of BJ, of all people, and it tastes sweet and spiced on his tongue, fuels him to push onward.

"Not what your parents planned for, I figure." BJ shrugs and pulls a caricature of sympathy on like a mask, dripping just the edge of condescension into his tone. "I mean, they've got you in line to play husband for, what, a Vanderbilt? A Rockefeller? And here you are with your legs spread for a Hunnicutt from California. But they've got it all wrong." As BJ looms over him, he takes Charles by the jaw again and watches with a thrill as his mouth falls open. "You rich types, you're lucky to get an heir at all. You never mix it up, you know? Never bring in any new blood. It's just the same tired gene pool, the same old story, and it's gonna make all your fancy names die out one day.

"See..." BJ leans closer, thumbs over his bottom lip, watches a rare sheen begin to form on Charles's distinguished brow. "...it's guys like me who make it happen. Filthy little rats with names nobody'll ever remember." And as he carefully shifts his hips, he aligns their cocks—lets his own obscure Charles's more modest length—but he makes very sure to let the weight of his sack drag along Charles's sensitive base, and when the man beneath him sucks in a shaky breath, BJ knows he has him, hook, line, and sinker. "I'm not even gonna have to try to breed you. The second I'm filling you up, it's a done deal, darling. Yeah, you'll get your baby. But there's not a ballroom in all of Boston that'll let her debut. So the way I see it, you're about to be the luckiest girl around." BJ can feel his smirk go toothy, his eyes sparking, as he settles the full weight of his broad body over Charles's soft and round figure. "I'm about to give you your ticket out of there."

It must hit like a truck with the way that Charles suddenly groans and writhes under him, his mouth closing around BJ's thumb so he can press his teeth into it just at the edge of pain. Yeah, no, that's exactly what BJ thought. Maybe he likes the money, the staff, all those perks, but they both know that high society's got more rules tacked on than the whole goddamn Army. From what BJ's heard, one Winchester has already found her a few doorways out of the hellscape. Maybe Charles needs a little more time to make his own—but maybe helping him burn off a little of that tension won't hurt either.

"Shh, shh, it's all right." He pushes his thumb in further and doesn't try to hide his deep moan when Charles gives it the tiniest suck. It seems like it might've been instinctive—Charles freezes and blinks—but as BJ gives another quick thrust, he flushes and sucks harder. "I'll take care of everything. You've got one job: just lay back and take my cock." As Charles thrashes again with a small, pitiful sound, BJ sits back so he can align himself with his target. "No, c'mon, sweetheart, spread them like I know you want to." He's a little rougher than he means to be when he sinks his fingers into Charles's thighs and pushes them open, but the sight of Charles dripping arousal onto his stomach only kicks up his excitement another notch. "You don't need to play cute with me. You've been waiting for some no-good fella to knock you up for years now."

"H-Hunnicutt, y-you..." Though he tries his best, Charles only stammers wordlessly after that, the reverberations alternating between pinched and trembling.

He tracks it, then, how Charles is stabbing his nails back into his body. That won't do at all. This is a game, not a punishment. Before he can second guess the urge, BJ redirects Charles's legs toward his chest instead. "Here, gimme your hands. Need you to hold your legs out of the way for me, all right?" Though he's not sure Charles is even tracking specifically what he's saying, those soft and lovely fingers are offered to him all the same, and BJ leans down, kisses both palms, then guides him to pull his knees back as far as they can comfortably go. It's the doctor in BJ that makes him skim down his hamstrings, just a quick feel to make sure he isn't straining his biceps femoris or semitendinosus on either side. Only when he's satisfied does he cup the base of his own cock.

"That's it," he coos. Honestly, he expects Charles to clamp down when he feels BJ's tip rubbing against his hole—rejecting his body one last time before giving in—but he doesn't. No, he relaxes further, like he's trying to suck him inside. "God..." Charles wants him. Really wants him.

He has to take a breath and shake the shock out of his head before he's too overwhelmed by the fresh surge of desire.

With a groan, BJ begins to ease carefully in. "C'mon, let me in... Juuuust like that... Fuck, Winchester." The surname comes first, tastes filthy on his tongue. There isn't a universe in existence where this should be happening, yet here they are, Charles gasping and staring up at him with wild eyes, BJ fighting not to bite a hole through his lip as he represses the urge to sheath himself with one thrust. "Oh, you needed this, didn't you? You just need somebody...to take it all away."

Confusion drifts across Charles's face like a cloud. BJ watches it carefully, prepared to pull back. But miraculously it passes by, and in its wake, Charles furrows his brow and arches experimentally, taking him in deeper. He groans and squeezes around BJ's length for the first time, a fiery pulse of ecstasy that has BJ doubling over and catching himself on Charles's shoulders. "Hunnicutt, I-I want..." They lock eyes, searing blue on blue. "Don't... Don't take it easy on me. Do you understand?"

He's hit with such a spike of arousal that he curls tighter with a long, shivering groan. "You don't wanna be a delicate flower, Winchester?" BJ teases breathily.

"Not on your life," Charles grits out.

BJ grins as he catches his gaze one more time. "You're right. I haven't forgotten. You're good..." He bucks a little deeper. "...hardy..." Another thrust, further still. "...breeding stock." One last push crushes his pelvis against Charles's ass, and BJ hums in appreciation as he cups his cheeks in both hands and gives them a squeeze. He's stretched obscenely around BJ's cock, but all the same, he fits him just right. No straining, no swelling that's suggesting any kind of damage from rough treatment.

He makes a mental note to check him over again once he's finished fucking the hell out of him.

Since he needs to make sure they both have a moment to really adjust, BJ looks over the rest of his body, the gorgeous shape of him, soft folds here, a more solid swell there. When he gets caught on Charles's pectorals, he figures why not, then grabs one none too gently. "Mm, these are gonna be so fucking pretty. Nice and big. They get more sensitive as they start filling up, you know that?" As he thumbs over his nipple, an almost startled whine come out of Charles as it hardens, and BJ grins. "Maybe I'll come by and check on them every day. See how they're growing. And don't worry if they start feeling sore." It's curiosity that has BJ pinching and rolling it between his fingers, but the way Charles white-knuckles the edge of his cot while he gasps tells a beautifully evocative story all the same. "A nice, hot mouth'll take care of that. And I'll make plenty of time for you."

"If you don't...fuck me..." The words sound as though Charles is fighting against God himself to find them. "Hunnicutt, I-I will not appreciate it if you draw this out much longer."

For the first time, BJ's taken aback. Has he misread all of this? Sure, the man underneath him is hard enough that he's dripping yet another bead onto the slick pool on his stomach, but that doesn't mean a damn thing, does it? Just physiological. BJ plants a hand right by Charles's head and leans down. "You done playing, Charles?" he asks softly as though there's an audience to hear and make Charles feel humiliated.

Charles wrinkles his brow one more time. "Not on your life, Beej." But try as he might, the way he murmurs that nickname only makes BJ want to kiss him. "If you—" He cuts off abruptly as he glances over the shape of BJ. There's a clear appreciative gleam in his eyes as he skims over his shoulders, his arms, and BJ bites his bottom lip with a smile and fights not to flex for him. He fought hard to find a little humility while he was in medical school, but his jock side never lost it. "I am merely suggesting...that I'd rather you have me while I am still able to enjoy it."

BJ blinks a few times. Glances between them. Charles's cock is curved far enough that it is, in fact, sticking to his own stomach now.

"You did need it," BJ murmurs with a certain degree of stunned delight. When he meets his gaze now, he feels like a scamp, like he's getting away with breaking all the rules somehow, having everything he was never supposed to. "Okay. Okay, yeah, Winchester. You want me to make it good for you before I knock you up?" He sits tall on his knees to the sound of Charles's first murmuring moan, pulls out and pushes back inside with experimental force to charm out the second one. "I guess I can do that."

It doesn't take long for BJ to realize that Charles, whether he's taken it in the ass before or not, is in fact not kidding when he said that he doesn't want to be treated gently. Only a few thrusts later, Charles is reaching for BJ's hips and yanking at him. It's enthralling. He can't remember the last time someone this unexpected needed BJ to ruin them.

"Mmm..." BJ lets his eyes fall shut and his lips part as he gets a little lost in the rawness of this kind of sex. With Hawk, sure, they get a little primal sometimes, but it's always tinged with a startling amount of intimacy as though they're trading souls for a short while, trusting the other to put them back where they started rather than letting them be lost at sea. But this is different. It's not casual, exactly—Charles is far more than a colleague, most certainly a friend, and ultimately is someone who BJ can't really imagine a future away from forever. But it's less overwhelming than it ever has been with Peggy, with Hawkeye. Somehow there's less to worry about here.

It's a vital moment of connection. He wouldn't want to play like this with anyone in camp but the two people who live in this very tent. But it's also just...oddly reaffirming of their friendship. A little fun that's a lot closer to the chest than it would be if it didn't mean anything.

As BJ brings himself back into the present, out of the lush waves of physical pleasure and the sparking playfulness that overlays it, he puts his hands on Charles's thighs and lets his bunkie's fall away. "You feel so fucking good, you know that?" BJ purrs. "You were made for this. Made to take cock and be bred. No wonder you're such a pampered thing."

"Ohh..." Charles's flush has spread all the way down his neck and into his chest, a lovely bloom to match the heat right under BJ's skin.

He gets lost just then in watching how Charles's body moves under him. "Gorgeous," he breathes. He's so—

"For God's sake, Hunnicutt," Charles gasps out, stabilizing himself with a hand on the bar above his pillow, rolling his hips down to meet him in the middle with a sense of desperation. "Harder, harder, don't let up now."

The commands are the closest thing he thinks he'll ever get to begging from Charles, and that fact undoes him, practically blisters his brain. "Fuck, Winchester..." He quickly renegotiates the space, shoving the pillow a little further up with his knee, then opening him up as wide as he can with that firm grip on his thighs. His jaw clenches. As he rises to the call with a punishing pace, his muscles begin to burn in a pain that's sweeter than any sprint has ever given him. "You're taking me so deep." When he flicks his eyes up, he zeroes in on how Charles is bouncing with the force of his thrusts, the way that his mouth's gone slack. "You feel it, doncha?" BJ bites his bottom lip, pounds him so his balls are slapping against his skin. "Feel how much I've got, mmnh, to pump you full of? Think you've got room inside you for every fucking drop?"

Charles lets out an almost frantic whine, his hand snapping between them to find his cock and strip it, matching BJ's rhythm.

"Yeah, that's it, that's it," BJ coos. "Oh, you can't wait for it, huh? No, you've gotta milk me dry when you come, is that it?"

Charles's noises border on overwhelm, and if this was any other person, any other situation, BJ would pull back and check in, but this is what he needs, it's what both of them need, practically ripping the skin off their bones with how hard they take this.

BJ stares unblinkingly, painfully, right at Charles's hand, finding growls breaking free from his own chest as a visceral way to stay focused, not slow down. It pays off. The moment he thinks his body's about to cramp up, Charles gasps, throws his head back, and comes with a shocked cry.

"Fuck, that's it. Fuck, Charles." It's intoxicating somehow, watching this man make himself absolutely filthy, jet after jet streaking his body. He's not even sure where the words that bubble up are coming from. "That's right, waste it, you don't need it, I'll take care of everything, darling, you just... Nnh, fuck!" He didn't plan it, not even for the illusion of what they're playing at, but as he explodes inside of him, BJ buries his cock as deep as he can go, even grabs his hips in a bruising hold so he can push him into the tightest ball possible. He's absolutely shameless, grunting out raw, animalistic sounds as he ruts against his ass.

And then he does feel the twinge in his leg, and just like that, down he collapses.

"Hunnicutt!" Charles bellows at the top of his lungs. "You—" He tries to push BJ away, then trembles from head to toe and goes limp instead.

"Just gimme a sec." BJ fights to catch his breath. While he fumbles behind himself to find the back of his thigh and massage his hamstrings, it takes him a moment to realize Charles is still shivering. He's buried his face in BJ's neck and, what's more, he's the one rutting right there against BJ's abdomen. He chuckles. But when Charles stiffens, BJ's quick to murmur. "Y'know, that's a hell of a compliment, what you're doing right now. That was really something, wasn't it?"

Little by little, the tension in Charles's body melts away one last time. "It was...quite educational."

BJ rolls his eyes. A ringing endorsement.

"Perhaps we might..."

It feels like he might've gotten away with not cramping up. BJ hums contently as he comes up on his elbows and looks down at Charles with a sated smile. "Might what?"

Charles clears his throat. He tentatively meets BJ's eyes, then looks away immediately. "You did say that Pierce is...nearby, did you not?"

Realization comes in like a fresh, spring breeze. BJ's eyebrows raise as he reaches between them and rests his palm on Charles's sticky belly. "Y'know, I haven't fucked him yet today. He hasn't come in at least twenty-four hours." When Charles trembles once more, BJ's grin spreads wide enough to hurt. "Mmm, Winchester...you're right. It really would be a shame to leave a job half-done."
