3 Months Later

Y/N traipses down the iron stairs into the war room, her little skirt flipping temptingly around the tops of her thighs. Sam smirks to himself, pleased she’d followed his instructions to wear something with easy access. Jack and Y/N smile at him when they reach the bottom of the stairs, and he gives them a wave and a smile of his own in return, before Jack leads Y/N down the hall and back towards his bedroom. 

“Hey there, Y/N,” Sam hears Dean greet her in the hallway, and a moment later his brother rounds the corner carrying a plate full of french fries and a beer. 

“So,” Dean sighs heavily, dropping into the chair next to Sam, “we should go out tonight. Hit the town.” 

“What?” Sam asks, trying to finish translating the page of Enochian he’d been working on all afternoon. He’s especially eager to finish now that Y/N’s arrived for the evening, knowing exactly what she and Jack are doing in the boy’s bedroom right now. He doesn’t want Dean distracting him and delaying him further. 

“Let’s go out,” Dean repeats, shoving some fries unceremoniously into his mouth as he speaks. 

“Oh,” Sam hesitates then shakes his head, “nah, not in the mood.” 

“Come on,” Dean complains, “I don’t wanna stick around here with those two doing God knows what just down the hall, let’s leave the lovebirds alone and go find some lovebirds for ourselves, huh?” he tweaks his brows invitingly and Sam laughs. 

“No, really, I think I’m good here,” he smirks, leaning back in his chair and pushing away the book, finally finished with it. 

“Dude, it’s been ages, let me be your wingman, we’ll get you… someone nice and pretty to spend a little time with,” Dean smirks, punching Sam on the arm and Sam laughs, noticing Dean’s obvious avoidance of gendered terms. He’s been getting better at that since Sam and Jack had started discussing their bisexuality more openly, and he does appreciate the effort. “You’ve gotta get laid, my balls are gettin’ blue just lookin’ at ya.” 

“Dean, seriously, I’m good,” Sam protests, shaking his head and standing to return the book to its shelf. He wasn’t sure why he was being so coy about the fact that he was involved with Jack and Y/N. They’d discussed it previously and decided they’d all be fine with starting to tell people that the three of them were in a proper relationship, but Sam hadn’t figured out the best way to bring it up with his brother yet. And he still isn’t sure he wants Castiel to find out. Facing angelic retribution for defiling Cas’s adopted son isn’t on Sam’s bucket list, quite frankly. 

“Look, man is this…” Dean trails off, looking around as if he’s afraid of being overheard, then leans forward and half whispers: “Is this about Jack? I mean, I know you guys kinda… messed around or whatever, while you were teaching him things. He told me about it before I could stop him,” he elaborates upon seeing Sam’s look of shock. 

“Oh,” Sam hesitates before returning to his seat, suddenly nervous. “I didn’t realise you knew.” Dean just shrugs, clearly he hadn’t wanted to bring it up with Sam if he didn’t need to, but apparently it felt necessary now. 

“Are you like, into him, still?” Dean asks cautiously, and now Sam understands why Dean has been so eager to get him out of the bunker every time Y/N has come over in the past few weeks; Dean thought Sam would be uncomfortable seeing Jack dating someone else. Sam finds himself oddly touched by the thoughtfulness. 

“Uh, yeah, I guess I am,” Sam nods, trying not to burst out laughing. He may as well make this conversation entertaining for himself if now’s going to be the time to have it. Dean nods sympathetically, his lips pushing out in a serious pout. 

“Let’s get outta here, then. You just need someone to help you get over him. You haven’t slept with anyone since him, have you?” Dean says, more as a statement than a question, and Sam blushes remembering all the instances where he has slept with someone other than Jack – Y/N. His mind flits to what she and Jack must be doing right now, though he’s smug in the knowledge that they won’t be going further than heavy petting until he joins them. They don’t have permission to. 

“No, I have,” Sam reveals, deciding not to draw this out any longer. 

“What? Who?” Dean’s visibly taken aback, probably running through the opportunities Sam would’ve had for a one night stand recently. 

“Y/N,” Sam replies, enjoying how Dean’s mouth drops open comically. 

“You slept with Jack’s girlfriend?” He’s aghast. 

“Yup.” Sam confirmed placidly, watching Dean’s increasing disbelief. 

“No way, dude,” he shakes his head, taking a sip of his beer. “I’m not buyin’ it. She’s like nineteen, no way she slept with you.” 

“Well, it wasn’t just with me, Jack was there too.” 

Dean chokes on his beer. Sam can’t stifle his laughter any longer. 

“You’re fucking with me,” Dean insists, eyeing Sam suspiciously. “What, you’re tellin’ me all three of you slept together? No fucking way,” he shakes his head, refusing to believe it. 

“I’m not just sleeping with them, I’m dating them,” Sam explains. “It’s all three of us.” 

“You’re tellin’ me that sweet little girl in there has two boyfriends, and one of them is almost double her age, and she lets you both fuck her at once? No. Like, no, no way.” Dean is in full on denial. 

“What, you don’t think Y/N’s kinky? Or Jack?” Sam questions him, smirking. 

“You’re not kinky!” Dean’s voice leaps in volume and in pitch as all his preconceptions come crashing down around him. 

“What do you know about my sex life, Dean? Really?” Sam asks, crossing his arms, and waiting patiently while Dean sputters, trying to find an answer. 

“I just know you’re messing with me. You’re not in some weird kinky threeway couple with them.” 

“I’m not?” 

“No,” Dean shakes his head emphatically, as if his is the final word on the matter. 

 “Okay,” Sam shrugs, getting up from his chair and leaving Dean at the library table, heading towards Jack’s bedroom. 

“Wait, where are you going?” Dean shouts after him, following Sam down the hall. 

“You wanted me to get laid,” Sam shouts back over his shoulder in explanation. Dean follows him all the way to Jack’s room, and Sam looks back to his brother with a smirk as he knocks on the boy’s door. It swings open a second later to reveal Jack, flushed and out of breath. 

“Hi, Sam,” he beams up at him genially, and Sam hears Dean come to a halt just behind him. “Hi, Dean,” Jack leans around Sam to give Dean his customary stationary wave. 

“Hey, Jack,” Dean replies suspiciously, glancing between Sam and Jack in the doorway, and where Y/N is on the bed. 

“Are you coming in?” Y/N asks, and Sam supposes her question could be aimed at both of them, which clearly Dean takes it to mean, because he follows Sam and Jack into the room. 

“So,” Sam clears his throat awkwardly when Dean continues to just stand there, staring between the three of them. “I told Dean about us.” 

“Oh, cool,” Jack nods, sitting down on the end of the bed. Dean continues to look around the room perplexedly, the silence growing awkward very quickly. 

“Dean doesn’t believe that we’re all dating,” Sam finally breaks the silence, snickering, and looks of comprehension cross over Jack and Y/N’s faces. “He doesn’t think we’re that kinky.” 

“Does dating two people mean I’m kinky?” Jack asks, looking to Sam for an answer, and Sam shakes his head. 

“No, it doesn’t. But some of the other stuff we do does make you kinky,” he smirks down at the boy, and Jack blushes, clearly remembering something specific. Sam thinks he has a lot of memories to choose from. 

“What the hell?” Dean asks no one in particular. 

“You two,” Sam turns to Jack and Y/N, “present.” 

“Yes, Daddy,” they both answer automatically, climbing off the bed and walking to Sam, dropping to their knees at his feet. 

“Good boy, good girl,” Sam smiles, caressing their cheeks gently, proud that there had been no hesitation for either of them, even with an audience. That was something he could have fun exploring in the future.  He looks up to Dean, pleased to see his brother standing there in stunned silence. He’s achieved what he wanted to with his little stunt. 

“Could you give us some privacy, Dean? I need to reward them for listening so well.” Dean is out the door barely a second later, and Sam closes it behind him with a laugh, turning back to his subs and letting the anticipation spread through him. “Back on the bed you two, and strip.” 

They obey him quickly, and without question. Sam thinks he’s never met anyone as naturally submissive as Jack and Y/N are in the bedroom. Jack enjoys the times Sam gives him more control over Y/N, but he still falls back into his role as a sub seamlessly every time. Y/N has never been very comfortable being dominant, though, the times Sam had asked her to try; she’s happy where she is, and truthfully Sam finds that incredibly attractive. 

“You both waited for me to get here, didn’t you?” Sam approaches them with a smile, beginning to strip out of his own clothes as he approaches the bed. 

“Yes, Daddy,” Y/N nods, looking up at Sam with wide, innocent eyes. 

“Neither of you touched where you weren’t allowed to?” he checks. 

“No, Daddy,” they both shake their heads. 

“Very well done,” Sam approves, climbing into bed with them both. “C’mere,” he pulls Jack into his arms and kisses him, bundling the boy against his chest and plundering his mouth with his tongue. Jack starts moaning against him and Sam feels himself starting to get hard. The bed moves and he feels lips on his shoulder, and breaking the kiss he looks down to find Y/N staring up at him with pleading eyes. 

“Kiss me, Daddy?” she asks so sweetly, and Sam instantly gets harder. Even though he knows she’s far from innocent, she still sounds like she is. 

“Of course, baby girl,” Sam pulls her in and kisses her deeply, keeping Jack pressed into their sides as well, and a moment later he takes the hint and joins in, kissing along Y/N’s neck and beginning to suck a love bite into her skin, which has her moaning into Sam’s mouth in no time. 

“Do you know what you want for your reward, for being such a good girl?” Sam asks when he pulls back to watch Jack kiss down her body. He’s made his way to her chest now, sucking one nipple into his mouth, and Y/N moans appreciatively. “You both get to choose one reward tonight.” 

“Can– mmmh,” she moans when Jack inches his hand between her legs to begin playing. 

“Is she wet yet, baby boy?” Sam asks casually, though he’s much more interested in the answer than his tone would suggest. 

“So wet, Daddy,” Jack’s reply is muffled, because he hasn’t taken his lips off Y/N’s chest yet. 

“Good girl,” Sam slides a hand over her cheek and lets her nuzzle into him. “You always get so wet for us, don’t you? Are you gonna tell Daddy what you want?” 

“Can I ride Jack, Daddy? Like you showed us the first time, with you touching me?” 

Sam feels his dick twitch at the memory. “Absolutely you can,” he nods, already eager to watch. 

Jack moans deeply as Sam guides Y/N down over his cock. She’s straddling him, her tiny hands pressing down into his chest to hold herself up, and Sam has one hand on Jack’s cock to hold him steady while he’s guiding Y/N’s hips with his other. When his tip slips inside her for the first time Jack feels his cock jump in reaction to the tight, wet squeeze of her, and she only gets tighter the deeper he goes. 

“Oh my god, Sam,” Jack groans when Sam’s hand drops from his cock and moves to his balls, fondling them as Y/N stays still, getting used to the feeling of him inside her from this angle. Sam had told them Jack would feel deeper in this position than any other. 

“Don’t talk to me, baby boy,” Sam chuckles darkly, still playing with Jack’s balls, rolling the sensitive flesh against his palm. “Tell Y/N how good she feels, she’s the one you’re fucking, after all. Don’t want her to feel left out.” 

“You feel amazing, Y/N,” Jack sighs, his hips rocking involuntarily, trying to create more friction between them. 

“Thank you, Jack,” Y/N responds breathlessly, remembering her manners. 

“So fucking good,” Jack groans, loving the feel of her wetness surrounding him. She’s so slippery inside, wetter than he’d imagined it would feel, and so much warmer than the fleshlight Sam had given him to practice. The heat of her body is intoxicating, and it’s everywhere, not just around his dick, because Sam pushes on Y/N’s shoulders lightly and makes her lean forward, blanketing herself over Jack’s body so their lips can meet in a tender kiss. 

“You two are so beautiful together,” Sam tells them. Jack glows under the praise and he feels Y/N’s sharp intake of breath against his lips. “Want to see you fuck yourself, Y/N. Use Jack’s cock to get yourself off, baby girl.” Jack shivers happily at the prospect. 

“Yes, Daddy,” Y/N nods, and she slowly sits up, bracing herself on Jack’s chest once again and using the leverage to lift her hips a little and drop back down. 

“Oh, God,” Jack groans when she starts to squeeze around him with each stroke, wringing the pleasure from his cock. She’s sped up as well, fucking herself down more vigourously with every twist of her hips. “Fuck, fuck, don’t stop baby, please don’t stop,” he begs, feeling himself quickly approaching his edge. 

“Ah ah ah,” Sam admonishes him with a smile, reaching out to grab his balls and Jack hisses in pain as the older man tamps down his orgasm. “I didn’t say you could cum yet, did I?” Sam asks, and Jack shakes his head embarrassedly. 

“I’m sorry,” he apologises, eyes pleading, hoping Sam will be lenient with him, but he doesn’t appear to be in the mood.

“Y/N, baby, slow down,” Sam puts his hand on her shoulder and makes her sink all the way down on to Jack again, grinding her hips into his. “Yeah that’s it, just tease him baby girl,” he smiles wickedly down at Jack, and Jack groans. Though so far as punishments go, watching Y/N grind herself on his dick, keeping him locked inside her and clenching down tight, this could be a lot worse. 

As if Sam’s read Jack’s mind, he pushes himself between Jack’s legs and circles his hands around Y/N’s waist, holding her against his chest. He pulls her back a little, so Jack can see the base of his dick now, and where the shaft disappears inside her. Fuck that’s hot, watching himself move in and out of her body as Sam twists her hips the way he wants her to move, his only goal to tease Jack as much as possible at this point. 

Y/N’s head drops back against Sam’s shoulder as she moans out, beginning to lose herself in the sensations of her own pleasure. Jack can’t help but think she’s the most beautiful thing he’s ever seen, and he knows how to improve the view even more. 

“Make her cum, Sam?” Jack pleads, looking over Y/N’s shoulder at their mentor. “I wanna see her cum, again, please.” 

“You want her to cum on your cock, baby boy?” Sam quirks a brow menacingly, and Jack wonders if he’s made a mistake here somehow. “You want me to make her cum for you, make her writhe around with your dick in her body while I’m the one making her cum? You wanna feel her pussy clench around you? Think you can hold off if you feel that? I don’t think you’ll be able to stop yourself from cumming, baby boy. I probably couldn’t, with this cunt around my cock.” 

Sam holds Y/N to him gently as she grinds herself down on Jack’s cock, his fingers rubbing softly across her clit. She moves so sensually between them, molding herself according to Sam’s directions. He can feel when she’s close because she starts to shake with every inhale she takes. 

“Look so pretty on top of him, baby girl. Can’t wait to see what you look like in my lap,” Sam whispers against her neck, dropping a kiss over one of the hickies Jack placed there. 

“Can I cum, Daddy, please?” It’s Jack’s question surprisingly, not Y/N’s, and Sam chuckles. 

“I don’t know, this is Y/N’s reward, I think she should decide if she wants you to–” 

“Yes, Daddy, please,” Y/N interrupts Sam imploringly. “Want him to cum inside me, please.” 

“Want Jack to cum inside you baby?” Sam teases her clit more intently, planning to get them off together now that he knows Jack is so close as well.  

“Can he, Daddy? Please,” she whines, clearly close to the end of her tether. 

“I think that’s a good idea. Need you nice and wet so my cock doesn’t hurt you too much, huh, baby girl?” Sam coos, kissing her neck again. 

“Oh fuck, want you to fuck me Daddy,” Y/N bucks her hips harder into Jack, which in turn rocks her clit harder into Sam’s probing fingers. 

“You can as soon as you cum for me, baby girl, can you do that? Can you cum for Daddy?” 

“Oh my god, fuck, yes, yesyesyes!” Y/N’s babbling expletives trail off as her orgasm takes over her breath away, leaving her a shaking, groaning mess between the two men, practically melting back into Sam. 

“Fuck,” Sam hears Jack hiss under his breath, and he’s sees the boy’s hips jerk as he cums inside Y/N. He feels his own cock twitch at the thought of feeling what Jack’s left behind, pushing into the extra wet warmth of her cunt when she’s already been used once tonight. 

Sam pulls Y/N off of Jack carefully, letting her curl up on the bed, resting her head in her lap as she comes down from her climax. 

“Good girl,” Sam comforts her gently, stroking the hair from her face, relishing in the picture of peace that she creates every time she’s just cum. It’s one of his favourite sights. 

“Was I a good boy, Daddy?” Jack asks, eyes wide and pleading, but Sam can see the hint of mischief hiding behind the expression. Jack always likes to push his buttons a bit, asking for things he knows he shouldn’t, just to see how far Sam will let him go. Sam decides he’s feeling generous today. 

“You were a good boy too, Jack,” Sam nods, smiling when the telltale blush stains Jack’s cheeks, telling Sam how much the praise truly does affect him. “Have you thought of what you’d like for your reward?” Jack blushes even more deeply, his creamy skin turning a tempting pink, and now Sam is really curious. What dirty things has his baby boy been thinking about? 

“I’ve been practicing, like you told me to,” Jack starts, eyes darting reflexively to the nightstand Sam knows he stores his sex toys in, “and I think I’m ready.” 

Oh. 

“You think you’ve been a good enough boy to deserve that?” Sam raises a brow quizzically. Though truth be told, it wouldn’t matter to him if Jack had been on his best behaviour or had been the naughtiest sub possible – if he was ready to let Sam fuck him, Sam was going to do it. But it was still good to keep up appearances, maintain a little bit of discipline so Jack didn’t get too cheeky in the future. 

“Yes, Daddy, please,” Jack begs, sitting up so he can get his knees under him and bow his head, begging properly like his Daddy taught him to. “I’ve been so good, I promise, and I really want you to do it.” The boy keeps his eyes downcast until Sam reaches forward and lifts his chin gently. 

“You have been good, baby boy,” Sam agrees, smiling proudly, desperately trying to keep his own enthusiasm in check so he can maintain the appearance of cool serenity he strives for as their Dom. “Why don’t you get your toys out, and show Daddy how much you can stretch yourself for him, okay?” 

Jack jumps into action instantly, going for his toys and lube and beginning to stretch himself out for Sam. 

Sam stands up from the bed, moving Y/N’s head from his lap and gently raising her onto her hands and knees at the edge of the mattress, putting her pussy at the perfect height for him. She moans softly when Sam spreads her ass cheeks to inspect her holes, and he can see her muscles flutter a little as she clenches in arousal, causing cum to trickle out of her. The view is absolutely obscene, and Sam feels his cock throb with the need to bury itself inside her used-up cunt. Grabbing himself and giving his dick a few strokes, he lines up with Y/N’s entrance and drags his tip through the mess she’s leaking out, groaning deeply when he feels more of the warm liquid spill out of her onto his member. 

“Fuck, you were made for this, weren’t you baby girl?” Sam grunts as he finally lets himself push inside, moaning raptly when he finally feels her hot, wet channel clenching around him. It’s even better than he’d imagined. 

“Made for you, Daddy,” Y/N whimpers, her head dropping to the mattress as Sam begins to pound into her from behind. But now that he’s using her hole he ignores her in favour of watching Jack, who’s currently got three fingers buried in his ass, stretching and fucking it relentlessly. 

“Look at you, taking those fingers like a good little slut,” Sam moans. “Surely you’re stretched enough to take that toy now, wanna see you fuck that cock.” Jack nods weakly, unable to articulate a response, but he withdraws his fingers and replaces them with his toy as Sam asked. His ass blooms beautifully around the large silicone tip when he pushes it in, panting heavily with the effort and discomfort of having something so big inside of himself, but he manages it. When the dildo is all the way in, only the suction cup base still visible, Sam swears he can see the tip of it pushing on the underside of Jack’s stomach, creating a tiny bulge in the baby fat there. 

“Fuck, Daddy,” Jack cries, working the toy out of himself and back in, slowly opening himself up. “Feels so full,” he scrunches his eyes up tight. 

“Just you wait baby, you know Daddy’s longer than your toy.” Sam smirks when Jack moans at that reminder, “but I know you can take it. Look how beautifully Y/N is taking Daddy, just opening up and letting me use her however I want, huh baby girl? Such a good little fucktoy for Daddy, can’t wait to have another one to add to my collection,” Sam’s eyes flick over Jack’s body, and he licks his lips greedily. 

“Want you, Daddy,” Jack begs, now fucking himself hard on the fake cock, panting heavily with the exertion. “Need you to fuck me Daddy, use me too, please, pleasepleaseplease-” his pleading is cut short when Sam flings himself across the bed, unable to resist the boy any longer, and crushes their mouths together.  

“Up on your knees, boy,” Sam gasps when they pull apart, and Jack scrambles to get in position, turning around on his hands and knees so Sam can pull apart his cheeks and look at his asshole. The little pucker is a deep, puffy, red, all shiny with lube, and Sam feels his dick jump in anticipation of feeling this virgin territory around himself. 

“C’mere, Y/N,” Sam reaches around and pulls the girl close, diving a hand between her legs to push his fingers inside and gather the remainder of Jack’s cum, what he hadn’t already fucked out of her. “Gotta get you nice and wet f’me, Jack,” Sam grins down at the boy, spreading his own cum around his hole and pushing two fingers inside the tight channel. 

“Daddy, please,” Jack begs again, clenching around Sam’s hand desperately. 

“So fucking needy,” he croons mockingly. “Have you been taking lessons from Y/N? Gonna be a good little cocksleeve just like our baby girl?” 

“Mmhmm,” Jack whines, nodding eagerly. 

“What do you think, Y/N?” Sam turns to the girl, who’s sitting beside them and watching intently. “Should I fuck your little boyfriend in the ass like he’s beggin’ me to? Does he deserve it?” 

“Wanna watch you fuck him, Daddy,” Y/N sighs breathlessly. “Can I touch myself while I watch? Pretty please”? 

“You can touch yourself,” Sam allows, “but don’t you dare cum, you got that? You know you have to have a cock inside that pussy anytime you cum.” 

“Yes, Daddy, I know,” she agrees, “I’ll be good, I promise.” 

“Okay then, baby, you sit back and enjoy the show,” Sam grins, shoving himself into Jack without any more warning, wrenching a scream from the boy as he’s suddenly more stuffed than he’s ever been before. “Fuck, you’re so fuckin’ tight, Jack,” he groans, pulling back and settling into a brutal pace right form the onset. Jack is sobbing beneath him, but he can tell it’s from pleasure, and how completely overwhelming the feeling of finally being connected in this way is for Jack. Sam feels that too. 

“Y/N, sweetie, why don’t you give Jack a kiss? He’s doing such a good job,” Sam grunts, still fucking into him mercilessly. Y/N crawls up the bed to Jack’s face, laying herself down alongside him so she can sneak her head between his arms to give him a kiss. 

“Love you,” Sam hears her whisper softly, and he smiles to himself. He loves how quickly they’ve all fallen for each other; Y/N is head over heels in love with Jack and Sam, and Sam and Jack feel the same way for her. Sam’s feelings for Jack had been there long before they all became this little unit together, but now he didn’t feel any shame in giving them a voice. Sam has been in love with Jack for longer than he can remember. 

“You two are so beautiful together,” Sam lets himself voice aloud, loving how Jack blushes from the praise, and how Y/N looks away bashfully. “Jack, wan’ you to fuck ‘er,” Sam grunts, making himself stop thrusting into the boy so he can pull Jack up on his knees, flush with his own chest. “Lay down sweetheart, Jack’s gonna need somewhere to spill when I fuck the cum out of him.” 

“Yes, Daddy,” Y/N nods meekly, climbing beneath Jack and spreading her legs obediently. Sam grabs hold of Jack’s cock and runs it through the slick mess of Y/N’s pussy, which is positively dripping with her arousal. 

“C’mon, Jack, show me how good you can fuck her,” Sam eggs him on, and Jack pushes in with a deep groan. “Bet I can still fuck you harder though,” he whispers against Jack’s ear when he bends down and sheaths himself back inside the boy’s hole. Sam feels Jack nearly collapse beneath him from the sensations, but he just manages to keep himself balanced on his hands and knees. 

“That’s it, boy, use that cunt how it’s meant to be used,” Sam picks up a punishing pace. “Want you to cum inside the little slut whenever you’re ready, okay? Really fill her up, just like I’m gonna do with you.” 

“Oh my God,” Jack moans, breath catching in his chest as he attempts to control his own pace, but Sam’s thrusts overpower every move he’s trying to make, and he has to let the older man have his way with his body in the end. 

“Actually, I want you to cum twice baby boy,” Sam huffs, gritting his teeth in determination to not slow his own brutal pace. “I know that cock of yours is special, you can do that for Daddy, can’t you?” 

“Yes, Daddy,” Jack whimpers, his face buried between Y/N’s breasts and muffling his ever increasing pitch. “Fuck, gonna cum, gonna… don’t stop, Daddy!” 

“Not stopping until you fill Y/N up all the way baby,” Sam reassures him, and he can tell when Jack’s first orgams hits because his ass clenches around Sam’s cock, convulsing deliciously. Sam only just manages to stave off his own finish. “Good boy, Jack,” Sam rubs his back comfortingly but continues to fuck him through his release, hoping to spur him straight into another. 

“Oh my god, Daddy, can I cum? Pleasepleaseplease,” Y/N begins to whine, and picks himself up a little more steadily and lets Sam fuck his hips into the girl beneath them, trying to angle himself to rub against the spot inside her he knows she needs to get over the edge. 

“Course you can, Y/N,” Sam gives her permission, fucking Jack even harder to transfer his strokes down to her. “You squeeze Jack nice and tight, milk him for me, baby girl. Make him cum for Daddy.” Sam’s focus begins to drift as his two partners cum again, their pleasure ricocheting through their bodies and into his own. 

“Feel so full, Daddy,” Y/N mumbles, and Sam feels himself beginning to spiral towards his own climax. 

“Yeah, you all full of Jack’s cum, baby girl? Wonder if you’ll get knocked up, keep you full of something else for a while,” he smirks, knowing that Jack has a weakness for that idea. Y/N’s responsive whimpers hint that she’s not so against the idea either, at least so far as dirty talk is concerned. 

“I’m about to cum so hard inside you, baby boy,” Sam grunts, snapping his hips sharply against Jack’s ass. “Maybe I’ll knock you up too? Keep you both as my little breeders, give you another reason to call me Daddy. Would you like that, Jack?” 

“Oh my god, Daddy, yes! Please, please breed me. Fuck your cum into me, make me yours, please, Daddy, fucking hell. Want you to breed me, Daddy, wanna stay full-” 

“Fuck!” Sam hisses, finally losing it and shooting his load deep inside of Jack. He’s gripping his hips so hard it would surely leave bruises if Jack’s body didn’t heal the way it did. It’s a shame he doesn’t mark easily. “Fuckin’ take it, baby,” he grunts, pushing in with one final thrust before freezing in place and shivering through the final spurts of his release. “Fuck,” he gasp again weakly. 

The bed is a mess of tangled sheets and tangled limbs as they all part and roll, finding space to curl around each other and bask in the afterglow of their lust. Sam eventually extracts himself from the other two and tosses on his boxers to pad down the hall and start a bath running. On his way back he’s awkwardly cornered by a very grumpy older brother. 

Sam freezes, no idea what to say, unsure if Dean had heard any of what was going on in Jack’s room since he’d run out earlier. Eventually Dean clears his throat and speaks, though. 

“Look, I uh, sorry I didn’t believe you, before,” he grumbles, scratching at his neck for a lack of something else to do with his hands. “But I don’t need to know any more than I already do. And if you ever show me anything like that again, I’m gonna tell Cas to smite you.” 

Sam bursts out laughing. 

“Deal,” he finally manages to choke out, walking around Dean back towards the bedroom. “If you don’t want to see anything else, I’d steer clear of the first floor bathroom for the rest of the night, okay?” he calls over his shoulder, laughing again when Dean groans loudly in anguish. 

His night is only just beginning.
