Show Me Masterlist

Y/N leans happily into Jack’s kiss. She’s always loved kissing him; he’s sweet and shy about it at first, every time, then as soon as their lips part and their tongues meet it’s like some otherworldly force takes Jack over and he devours her. Jack trails his hands up her arms, winding them into her hair at the base of her skull and crushing her to him. Y/N moans as his tongue probes against her lips, opening to him eagerly. 

This kiss is different though, because Jack isn’t the only person in the room with her. Jack’s hands aren’t the only hands on her body. 

Sam is behind her, his hip pressed against the small of her back and down to the curve of her seat. He’s wound one arm gently around her waist, holding her body loosely against him. The vigour of Jack’s kiss is forcing her back, so her head winds up wedged on top of Sam’s shoulder. Jack climbs to his knees, making himself taller than her so they can continue kissing. His hands cradle her face, keeping their lips moulded together, and Sam shifts behind her, bringing one of his legs around so she can nestle between them against his chest. 

They’re moving backward suddenly, Sam tugging her along and Jack pressing her down, his hands dragging down her neck to cup over her breasts and squeeze. 

“Oh god,” Y/N gasps as Jack’s lips leave hers to pursue the curve of her throat, following her veins from neck down to shoulder, to arm, to wrist, tracing the patterns with his teeth and his tongue. Y/N follows Jack’s progress with her eyes, but when her neck begins to ache she lets her head loll back, where it comes to rest in Sam’s lap. She can clearly feel the bulge of his erection pressing against her cheek through his jeans, but he doesn’t move to make her touch it. Instead, he skims his fingers over her forehead, moving stray hair out of her eyes. 

“Good girl, Y/N,” Sam sighs, breathy and deep. “You just lay back and let Jack make you feel good, yeah?” He keeps brushing his hand over her hair, and the gesture is incredibly comforting. She’d been so distracted by Sam’s words, and the calming caresses, she hadn’t noticed Jack beginning to kiss down her chest, his fingers playing nervously with the buttons on her shirt. 

“Can I unbutton this, Y/N?” Jack lifts his head to ask, hope shining brightly in his blue eyes. Y/N nods shyly. She very much wants Jack to undress her. 

“Very good asking for permission, baby boy,” Sam comments, approving. 

“Thank you, Sam,” Jack beams under the praise, but quickly looks back to the task at hand, button by button revealing Y/N’s chest, then stomach. He’s gazing at her body in wonder, like she’s the most beautiful thing he’s ever seen. “You’re so beautiful,” he whispers, telling her as much, and Y/N feels herself flush in embarrassment, looking away from Jack sheepishly to hide her face against Sam. 

“Don’t hide, Y/N,” Sam admonishes her gently, turning her head back to look at Jack. “You are beautiful,” he assures her, petting her head again comfortingly. “You’re so beautiful, sweetheart. You’ve gotta let people tell you that.” 

“Okay,” Y/N says in a small, nervous voice. 

“And what should you say? When someone gives you a compliment?” Sam asks calmly, but with a firmness in his tone that sends an inexplicable tingle into Y/N’s stomach. 

“Thank you?” she guesses, trying to look up at Sam for confirmation of the right answer, but he keeps her head still, facing towards Jack. 

“Say it to him, sweetheart.” 

“Thank you, Jack,” she smiles, and Jack smiles widely back. He moves back along her body and leans in to kiss her again. 

Y/N winds her arms around Jack’s shoulders, pulling him down on top of her, maybe a little too eagerly. Jack clearly hadn’t been expecting it, and he topples down, his weight landing against her and knocking the breath from her lungs. She squirms beneath him a little, and gasps when she feels something hard pressing against her hip. Jack groans a little, light and high in his throat, when she gives an experimental thrust of her hips up into his. 

“I can feel you,” Y/N whispers reverently, grinding her hips up again, chasing Jack as he tries to pull away and take his weight off her. “No, don’t go,” she mumbles against Jack’s shoulder breathlessly, tugging him back against her and trying to wind their legs together so he can’t get away. “I like feeling you on top of me,” Y/N breathes, and this time when she thrusts up Jack matches her, grinding his hips back down, rubbing his erection between her legs when he shifts a little to the left. 

“Oh, God,” Jack moans, just as Y/N gasps: “Fuck.” 

“Did that feel nice, Y/N?” Sam asks, a smirk evident in his voice. He clearly already knows what her answer will be. 

“Yeah,” she nods vigorously, starting to kiss and suck at Jack’s neck, up his jaw, whatever bit of skin she could reach. 

“When she says something feels good, Jack, it’s probably a good rule of thumb to keep doing that thing.” Sam says with a chuckle, and Y/N laughs lightly too. 

“You’re right, Jack, he is a good teacher,” she smiles and kisses him again, feeling a little giddy. 

Jack isn’t given the chance to reply when Y/N takes control of their kiss, pressing her body up against his in rolling waves, timed with the undulations of her tongue tracing the insides of his lips. He moans deep in his chest, Y/N feels it vibrating down his body. She answers with her own satisfied hums, relishing the pleasant ache building between her legs every time Jack grinds against her. 

Her hands run down Jack’s back and find the hem of his shirt. She starts to tug on it gently, trying to coax the fabric off his body, when a pair of hands covers hers, stopping her progress. 

“I didn’t hear you ask permission, Y/N,” Sam scolds.

“Can I take your shirt off, Jack? Please?” Y/N quickly corrects her mistake, tugging at the clothing again. 

“Yes you can, Y/N,” Jack nods and smiles, peeling himself up off her body so she can pull the shirt over his head. 

“Y/N, why don’t you take this off too?” Sam runs the backs of his fingers lightly over the cup of her bra, and Y/N shivers. 

“Okay,” she nods, sitting up and shrugging her shirt off her shoulders. 

“Give me your hands, Jack,” Sam pulls Jack’s arms around Y/N’s body, guiding his fingers to the clasp of her bra. Together, they pull the hooks apart in one easy motion, and Y/N heaves a deep sigh as it falls away from her chest, exposing her to Jack for the first time. He drags his hands around her ribs, bringing them under her arms so he can cup her breasts in his hands.

“You’re so beautiful,” he whispers again, touching her reverently. 

“Thank you,” Y/N replies, her heart pounding in her chest as her breath struggles to flow through her lungs. 

“Good girl, saying thank you,” Sam praises her, leaning down and dropping a small kiss on her shoulder, which only takes her breath away more. 

“Thank you,” she mumbles again, basking in the attention. 

“Such a good girl.” It’s Jack who gives her the nickname this time, and Y/N finds she likes it on his lips just as much as she does on Sam’s. 

“You know what else good girls do?” Sam asks quietly, breath ghosting against the shell of her ear. Y/N shakes her head a little, waiting for Sam to go on. “They finish getting undressed.” 

“Okay,” Y/N agrees, squirming in her seat a little to reach the button on her trousers. From the corner of her eye she sees Jack giving Sam a giddy smile, and she giggles. 

“You too, baby boy,” Sam instructs over her shoulder, “get those off.” Jack stands up off the bed to strip out of his jeans and socks, which gives Y/N room to shimmy out of her own, leaving her in just her panties and Jack in his boxers. “These too, baby girl,” Sam skims his hand over the edge of her panties, fingertips tickling at her waistline, and she shudders against him. 

“Yes, sir.” 

She doesn’t mean to say it. She has no idea where it’s come from. She’s never called anyone ‘sir’ in her life before, not even at school or at work, but the word just appeared on the tip of her tongue and as soon as she had said it she knew it was right. The whispered ‘good girl’ from Sam confirms that it was the right thing to say, that he approves. She likes that feeling. 

Y/N sits up on her knees and pulls her panties down her legs, giving Sam the perfect view of her ass as she does. It takes an incredible amount of willpower to stop himself reaching out and grabbing her flesh in his hands, but he does resist. Tonight is about Y/N and Jack, he needs to focus on that. 

Underwear now discarded and dropped to the floor along with the rest of her clothes, Y/N sits back down between his legs and Sam reaches for her shoulders, guiding her back against his chest. Gently, he reaches down and presses her thighs open, then runs his hands further down her legs and lifts her calves to hook them around his own, so she’s held open for Jack. Y/N lets him manipulate her body easily, sinking into his frame as he arranges her the way he wants. 

Jack is watching the pair of them, clearly fascinated, hunger flaring in his eyes as his gaze drags across Y/N’s naked body, being held open for him like an invitation. 

“C’mere,” Sam beckons him back, and the boy crawls onto the bed, coming to rest on his hands and knees between their legs. “Do you want to touch her?” he asks smugly, knowing the answer. Jack nods eagerly, unable to tear his eyes away from Y/N’s body. “Ask permission, Jack.” 

“Can I touch, please?” Jack looks up expectantly, and it’s not clear whose permission he’s asking for, Y/N’s or Sam’s. It doesn’t matter at the moment, because they both give it. 

Y/N moans prettily as Jack skims his fingers between her legs, tracing over the folds covering her entrance. From his vantage point, Sam can just tell that she’s wet, the slick catching the light as she squirms against his hold on her body. 

“Now, here is a very important lesson, Jack. Pay attention, hm?” Jack nods and watches closely as Sam moves his hand down between Y/N’s legs. 

“Can I touch you here, baby girl?” Sam asks sweetly before he lets his fingers settle where they’re headed, and Y/N nods, whispers ‘yes, sir’ again, and he feels his dick throb in his jeans. “Thank you, sweetheart,” he gives her a light kiss on the back of her head to show his appreciation. 

“This is called the clitoris,” Sam points to the small bundle of nerves hidden beneath the skin at the top of her mound. “It’s very sensitive, and it makes girls feel really good when you play with it,” he skims his fingertips lightly over Y/N’s clit and she gasps quietly. “See?” Sam smiles up at Jack, who is watching Sam’s hand, transfixed. Sam continues to play with Y/N’s clit while Jack watches, showing him how to tease it; varying the pressure, tracing lightly in little circles, rubbing up and down over it, scissoring it between two fingers pressed together. 

“And it feels even better when you have something wet on your fingers, to help you slide over her skin easier,” Sam says, watching Jack absorb every bit of information he’s relaying. Sam takes his hand away from Y/N, and she lets out a small noise of discontent Sam can’t help but smile at. “Patience, baby girl,” he admonishes her lightly and she sighs, clearly trying to calm herself down. 

Sam lifts Jack’s chin with two fingers, makes the boy look at him; the blue eyes are dark, pupils wide with arousal. 

“Open your mouth for me, baby boy,” Sam instructs, and Jack’s lips part instantly, making room for Sam to slip two fingers inside the wet warmth of his mouth. “Get them nice and wet, help me make Y/N feel good.” 

Jack sucks eagerly on his fingers. It’s not the first time he and Jack have done this particular act, Sam found out early on that the nephil likes having something in his mouth. Sometimes he’ll suck on Sam’s fingers while he touches himself, and Sam is happy to let him do it, getting on with whatever he had been doing before Jack asked for help, letting the boy use his hand as a pacifier to help keep him quiet while he jerks off. Jack is also quite noisy a lot of the time; Sam had found that out early on, too. 

“Good boy,” Sam praises him, dragging his spit sodden fingers from Jack’s mouth and bringing them back between Y/N’s legs. He touches her for another minute or so, working her up until she’s squirming against him again. With his free hand, Sam reaches out to grab Jack’s arm, pulling him in closer and guiding his hand to Y/N’s entrance. 

“Feel how wet she is, Jack?” Sam asks, dragging his fingers through her slick. Y/N moans loudly when their fingers probe at her hole, bucking her hips slightly into their touch. 

“Wow,” Jack breathes, pressing his fingers lightly into the glossy deeper pink on display in front of him. 

“When she’s that wet, that means she’s turned on. Doesn’t it, sweetheart?” Sam smirks against Y/N’s neck, and she nods quickly. 

“Yes, sir,” she whimpers. 

“But we want to get her even more wet before you fuck her. And we want to stretch her out a little too, so it doesn’t hurt so much,” Sam explains. 

“How do we do that?” Jack asks curiously. 

“Push one of your fingers inside her,” Sam instructs and Jack nods sheepishly, taking a deep breath and easing a single finger into Y/N. She groans, hips wriggling, trying to press herself further into Jack’s hand. “Now you want to move it in and out, nice and gentle, okay?” 

Jack does as he’s told, carefully dragging his finger out and pressing it back in, building a gentle rhythm. Y/N’s whimpers pitch higher and sweeter the quicker Jack goes. 

“You’re doing so good, baby boy,” Sam coos, chest filling with warmth when Jack smiles gratefully. “See how good you’re making Y/N feel?” 

“Does it feel good, baby girl?” Jack asks Y/N sweetly, and Sam smirks to himself at Jack’s adoption of the pet name for her. 

“Mmhmm,” Y/N whimpers, “feels really good, Jack.” 

“Just you wait, sweetheart. It’s about to get a whole lot better.” Sam reaches down and takes hold of Jack’s wrist, slowing the movement of his finger. He pulls his hand back and it’s like Jack instinctively knows what Sam is going to ask him to do, because he immediately brings another finger up to join his first, pushing them both back into Y/N with a moan that matches hers. 

Sam uses his hand on Jack’s wrist to guide the boy, having him feel around inside Y/N’s body for the soft, spongy spot that would make her scream. When Jack finally finds it, they’re not disappointed. 

“Oh my god,” Y/N mewls, “don’t stop. Please don’t stop.” 

Sam lets Jack have control of his own movements again, trusting him to keep massaging Y/N’s g-spot. It goes without saying that if a girl is telling you ‘don’t stop’, you listen. Unless you’re trying to tease, but that’s a lesson for another day, Sam thinks to himself wryly. 

Y/N cums a few moments later, shaking in Sam’s arms as he soothes her, making sure to tell her what a good girl she was for them. He’s painfully hard, his erection wedged against the curve of her ass, which is nestled snugly between his thighs. But Sam knows his relief isn’t going to come any time soon. 

He still has a lot left to teach them.

Jack looks down at his fingers in astonishment, pulling them from Y/N’s body, dripping with the white of her climax. Without thinking about it he brings them to his lips and sucks them in, tasting her. He moans sharply, not expecting to like the taste as much as he does – it’s bitter, but sweet, and absolutely addictive. 

“If you like that, you’re gonna love this next part,” Sam smirks at him, and Jack feels himself blush, suddenly self conscious at his eagerness. “Don’t be embarrassed, baby boy,” his mentor reassures him, sensing his discomfort, “this is one of my favourite parts, too.” 

“What is it?” Jack asks curiously. 

“You’re going to use your mouth to get her off this time,” Sam tells him. “Lay down, I’ll show you how.” 

Jack follows the instructions happily, settling himself on his stomach between Sam and Y/N’s outstretched legs, Sam’s still hooked around hers, keeping her spread for Jack. Y/N sighs contentedly when Jack’s breath ghosts over her pussy, and he can see her hole twitch a little, which sends a throb straight to his dick. 

“What do I do?” Jack looks up to Sam for guidance. 

“Start by kissing her, just like you would if it were her mouth.”

“Where?” 

“On her clit, do you remember where to find it?” Sam asks. Jack nods and leans in, brushing his lips lightly over the small bundle of nerves at the top of Y/N’s pussy. “Good boy,” he hears Sam praise him, but it’s faint. He’s already thoroughly distracted by the new task at hand. Y/N had been so beautiful when she came on his hand just now, and the sounds she’d made had been so passionate, Jack is eager to get her to that point again. 

“Mmhm,” Y/N sighs, and Jack feels a hand drop into his hair, fingers tangling into the dirty blonde strands. It’s very clearly Y/N’s hand, it’s too small to be Sam’s. “That feels so good,” she murmurs. 

“Are you using your tongue yet, baby?” Sam asks from over Y/N’s shoulder. Jack can’t see with his face buried between Y/N’s thighs but he assumes she shakes her head because Sam continues his instructions. “Start licking her pussy Jack, want you to really taste her for me. I bet she’s real sweet, isn’t she?” 

“Mmhm,” Jack agrees, voice muffled because his mouth is still firmly pressed against Y/N’s skin. Carefully, Jack pokes his tongue out and runs it down through the folds of her pussy. The taste here is deeper, more difficult to qualify, and Jack wants more. He licks against her harder, scooping his tongue through the slick that’s leaking out of her, ducking his head to suck it off her thighs too. 

Y/N is moaning loudly above him, hips wriggling and hands clenching in his hair. The pain sends a pleasant tingle to his stomach. 

“Oh my god, Jack,” Y/N whimpers breathlessly when his tongue traces back up her skin to lick her clit. He massages his tongue gently around the sensitive spot, flicking across it after every few circles, and Y/N is getting so loud her groans are echoing through her body and vibrating into Jack’s. He thinks she might be getting close again, he hopes she is. 

“Put a finger back inside her, Jack,” Sam directs him, and Jack does, slipping a finger back into the warm clench of her body. “Now keep licking and kissing, but pay attention to how she reacts to each movement, okay? If her pussy clenches around your fingers, that’s a good sign. Keep track of those things.” 

“Yes, sir,” Jack nods, slipping into Y/N’s address for Sam unconsciously. 

With his finger back inside Y/N, he can feel exactly what Sam’s talking about. When he makes the small little circles around her clit, she sighs and relaxes, but when he sucks on it and flicks the tip of his tongue back and forth really quickly, her cunt tightens around him. 

“Oh, fuck,” Y/N swears, her walls clamping around Jack’s finger particularly tightly, and Jack finds himself laughing against her pussy. 

“You’re close, aren’t you baby?” he muses, fairly sure he’s reading the signs right. 

“Yes,” she mewls, clenching around him again as he continues to eat her out enthusiastically. “Fuck, yes, make me cum, Jack, please,” Y/N begs, fingers tugging harshly on his hair. 

“I think you should be asking for permission to cum, don’t you?” Sam whispers, loudly enough for Jack to hear, and a surge of arousal shoots through him so sharply he can’t help from grinding himself harshly against the bed. 

The pressure on his too long untouched erection feels so good, and Jack continues to hump at the mattress while Y/N grinds her hips into his lips and his finger. Adjusting his arm a little, Jack manages to slide a second finger back inside, and begins to feel around for her g-spot again. He thinks he’s found it when Y/N squeals and pulls so hard on his hair he feels a few strands part themselves from his skull. 

“Oh my god, ohmygod, don’t stop!” 

Her pussy is pulsing around his fingers now, and she feels like she’s soaking his hand and the sheets beneath them from how wet she is with her own slick and Jack’s spit. 

“Are you gonna cum, Y/N?” Sam’s voice is far huskier than Jack’s heard it all night. 

“Fuck… yes… gonna– don’t stop,” she moans, hips bucking against Jack’s mouth, chasing her pleasure. 

“What are you forgetting, sweetheart?” 

“Please can I cum, sir, please?” Y/N begs, close to sobbing. Sam chuckles darkly. 

“Not me you’ve gotta ask, baby girl. You’ve gotta ask Jack.” 

“Please, please please, let me cum, please!” Y/N squeals, and Jack has the feeling that even if he says ‘no’ she won’t be able to stop herself. 

“Cum, Y/N,” Jack groans, suddenly right on the brink himself. “Want you to cum for me.” 

Y/N’s words are indistinguishable as she finally lets go, shuddering through her climax. Feeling her lose it against him, because of him, for the second time in such quick succession, has Jack spiralling. He feels a gush of warmth against his hip as his body goes rigid, cum pushing out of the tip of his cock and into his boxers. 

They’re both panting heavily as they come down from their highs. Jack’s fingers are still inside Y/N’s pussy, and her hands are still tangled in his hair, like she’s scared she’ll fall if she lets him go. Jack secretly hopes she never does.
