summary: Sam has a thing about control. So when the pieces don’t quite fall into place—when a hunt goes a little sideways, for example—Sam can get a little…twitchy. Antsy, irritable. What you’ve learned, though, is that it’s all too easy to give him back that control. To let him take it from you.

Sam has a thing about control. You can’t fault him, of course; it’s actually sickening to think about how often his autonomy, his freedom of choice, has been wrested from him. Him turning into a bit of a control freak seems, frankly, like the best case scenario. It does mean that when the pieces don’t quite fall into place—when a hunt goes a little sideways, for example—Sam can get a little…twitchy. Antsy, irritable; you love him to death, but he’s a damn terror to be around when a hunt doesn’t go your way. What you’ve learned, though, is that it’s all too easy to give him back that control. To let him take it from you.

Two thick fingers press into your cunt, slow and leisurely, like he’s got all the time in the world, like you’re not falling apart in his lap. Like he doesn’t have you so wet it’s probably dripping down his wrist. He has your legs hooked over his, keeping you spread and open for him as he teases you. His smirk presses to your temple, your cheek, just below your ear as he plasters your face with soft kisses. “You’re doing so good,” he mutters, his lips brushing against your neck with the praise. “So perfect for me, you sound so pretty like this. Tell me when you’re close, okay, baby?”

God, you’re not sure you’ll ever get there like this. “Sam, please.” You’re not above begging, not in the slightest, especially not right now. You feel like you’ve been here for hours, panting and whining on Sam’s lap. For fuck’s sake, you’ve still got your sweater on.

You feel more than hear the little laugh your whine drags out of Sam, a rumble in his chest where you’re plastered against him, a puff of air against your throat. “You need some help? Hmm?” he asks, dragging his unoccupied hand up your stomach and rucking your sweater up as he does. At the same time, his fingers curl inside you, stealing your breath and sending your head lolling back on his shoulder.

“God—” Your hands scramble to grab onto something, anything, searching for purchase. In the end, one lands on Sam’s wrist as his hand cups your breast, the other grasping at the sheets below you, twisting them in your grip.

His thumb brushes over your nipple, drawing a choked whimper from your throat. “Answer me, baby. Can you come like this, or do you need more?”

How are you even supposed to think like this, let alone speak? “Fuck, Sam—” you manage to babble out, turning your head to hide in the crook of his neck. The smell of him floods your senses, pine and musk and just a little bit of sweat that lets you know he’s not as unaffected as he pretends to be. “More. I need more, please.”

“There you go,” Sam coos at you. Then he shifts the angle of his hand so the meat of his palm grinds against your clit with every thrust of his fingers, dragging a guttural moan from your throat in the process. “That wasn’t so hard, was it? My good girl.”

Curses spill from your lips like a chant as everything ramps up tenfold and leaves you struggling to keep up. Sam’s fingers, practised and precise, drag against your g-spot with every thrust and, combined with the pressure against your clit, they have you moaning and babbling incoherent pleas in moments. Your chest heaves with your panting, gasping breaths as the pressure in your gut grows and twists and builds until it threatens to send you careening over the edge.

Sam’s wrist twists in your grip until you release it, letting that hand fall to white-knuckle the sheets below you with the other one. With his hand newly free, Sam draws his fingertips along your jaw and tilts your head up until he can see your face. “You’re so beautiful,” he says, sweet as candy, as if he’s not taking you apart. “Talk to me, baby. How’re we doin’?”

Oh, he’s such a dick; he knows how you’re doing. Your pussy is pulsing around his fingers like a heartbeat, he knows damn well. He just wants you to say it. But you know what game you’re playing. “Sam…”

He presses his thumb to your lips, and his turn down on a frown that you know—you know—is performative, but that puppy look still digs its claws into your head. “Come on.”

“Oh, fuck—” Sam curls his fingers, and your gut pulls so tight you almost forget to breathe. “Okay, I’m close, God, Sam, please—” You know it's coming, but it still comes as a stone cold shock to your system when Sam’s fingers still inside you and the pressure of his palm disappears from your clit. Your cunt flutters as the bliss that had been moments away fades out of reach; your thighs futilely trying to close, press together, but you're stopped by Sam’s legs holding them open.

Sam carefully unsheathes his fingers from your cunt, and you could damn near sob.

He coos over the sound of your whine. “I know. But you're so pretty like this, sweetheart, so good for me.” His hand leaves your face to catch yours as you reach down to finish the job yourself, bringing it up to press a kiss to your knuckles. “Uh-uh. You trust me, don't you, pretty girl? I’ll take care of you.”

You narrow your eyes, glaring even as you twist your hand to tangle your fingers with his. “You’re evil.”

His laugh puffs over your lips as he leans down to press a quick kiss to them. It’s a little uncoordinated, and certainly not the best angle. But it’s a sweet apology. “Maybe I just thought you'd rather come on my cock.”

Your next inhale is sharp, a response to the way his words make your neglected pussy flutter. You twist a little further, your nose bumping his with how close you are. “Are you gonna let me?” you ask, and your lips brush against his as you speak.

He hums, and his eyes crinkle with the grin that he presses to your lips. “Say please—” he murmurs, the words washing over you like a wave— “and maybe I will.” Your hand tightens around his.

God, but if the power trip doesn't look good on him. The word comes out on a breath, just barely a whisper of, “Please.”

Sam swallows the plea with a kiss, draws a gasp out of you as his teeth sink into your bottom lip and tug as he pulls away. “Please…what?” he urges, dragging a line of hot, open kisses along your jaw and down the line of your neck. “Come on. You want it, don’t you? Use your words.”

You tip your head back, and you’re sure Sam feels you swallow around your need because the next kiss he lands on your throat is biting. “Please,” you say again, “please let me come on your cock.”

Sam’s smile against your throat is so bright it almost burns, and he releases your hand from his grip. “Anything for you, baby.” He presses one last kiss to the base of your neck before his hands come up under your thighs, lifting you off his lap. “Come on.”

You help him maneuver you until you’re laying on your back on the bed, and you take the opportunity to stretch your legs out, groaning at the stiffness from having them in that position for so long.

Sam kneels beside you, his hands squeezing at your thighs. “You alright?” he asks. His hands smooth up your legs to your hips before he draws them back down again in a pseudo-massage.

You nod. “I’m okay,” you tell him, and then you let your thighs fall open to make room for him. You get the pleasure of watching his eyes snap from your face to your cunt, his pupils swallowing his irises whole. “Want you.”

He lifts his gaze to yours again, and he holds it as he hooks his fingers under the waistband of his boxers and pulls them down and off. “Whatever you want, beautiful,” he says, climbing over you and settling with his hips between your thighs before he pulls his shirt over his head. He tosses it aside and braces his hand beside your head.

Entirely shameless, you reach out to press a hand to his chest, admiring the solid planes of his stomach flexing as he holds himself up to hover above you. His muscles shift, a body perfectly designed to drag the tip of his cock through your folds. Your breath catches in your chest, your hand smoothing up and over his shoulders to tangle your fingers in his hair.

He smiles, then his hand settles on your thigh. “C’mere,” he mutters, drawing your leg up over his hip. Your other leg follows suit, your ankles crossing. Keeping him close. “There you go.” With that, he presses inside you. He slides in easy—you weren’t exactly hurting for prep—but the stretch of your cunt around him still has you groaning in tandem with him.

“Fuck, Sam—” you gasp as he bottoms out, his hips kissing yours. Somehow, you always manage to forget just how big he is until you’re so full you feel like you can feel him in your throat.

Sam’s hand that’s not currently holding him up drags the hem of your sweater up until it’s bunched around your shoulders, leaving you, essentially, bare for him. He trails his fingers down your torso, watching the goosebumps that bloom on your stomach as he traces your skin. “Good?” he asks, his voice tight with the effort of keeping still inside you.

“Yeah. So fucking full,” you moan, your eyes fluttering shut as his hand cups your breast. “But yeah, I’m good.”

“Good.” He draws out, dragging along your walls until only the tip is left inside, and you brace for the punch of the next thrust. But it never comes. He lingers, teasing, until you open your eyes to see him smirking down at you. “You wanna beg for it?”

“Oh, fuck off,” you groan, pressing your heels into his back in an effort to press him forward. He doesn’t budge.

“I think you’re gonna,” he says, ducking his head to press his lips to the hinge of your jaw. “You wanna come? All you have to do is say please—” He brushes his thumb over your pebbled nipple, pulling a whimper from your throat— “and then I’ll fuck you so good, you know I will. Just let me hear it.”

You turn your head to face him, staring him down, breathing in his air as you consider his proposal. You lift your head to brush your lips against his. “Please fuck me.” If you hadn’t been paying attention, you wouldn’t have noticed, but his hand flexes just so where he’s cupping your chest. “Sam. Please.”

Sam draws you into a proper kiss at the same time he slams home into you. Although, a proper kiss is maybe not the best way to describe it. It’s more Sam licking into your open, panting mouth, swallowing the desperate, airy moans that his thrusts are punching out of you. The pace he sets isn’t fast, but it’s deep, and with his tongue on your mouth and his hand on your tits, it feels like you can feel him everywhere, like there isn’t a single part of your body that isn’t being consumed by him.

“My beautiful girl,” Sam rasps as he pulls away. He drags kisses down your neck, and then skips right over the bulk of your sweater to scrape his teeth over your nipple at the same time his fingers pinch at the other. Your chest spasms on a sobbing moan, your nails scraping down his back, aching for purchase. The feeling is overwhelming, lighting up every nerve ending you have until the only thing you can think about is Sam—Sam’s mouth on your chest, Sam’s voice soothing heated skin, Sam’s fucking cock taking you apart. “You sound so wrecked, baby, look at you.”

“Sam—” His name drips from your lips like a mantra, over and over and over like it’s the only thing you can say anymore. You’re so close, teetering so close to the edge that a light breeze could push you over. “God, please—”

His hand abandons your chest, smoothing down your ribs and over your hip bone. “I got you. I said I’d take care of you, didn’t I?” he says, and then he flattens his tongue over your nipple as he shoves his hand between your bodies to rub at your clit.

It’s over—your whole body trembles with it, and you cry out as your orgasm crashes over you. Sam’s hips stutter where he’s fucking you through it, and then you feel him spill into you, the spasms of your pleasure having pulled him off the cliff right along with you.

“Oh, fuck—there you go,” he gasps, his hips slowing to a stop as you both ride out the recovery. “So perfect, so good for me.”

With the last of your energy, you lift your hands to his face to drag him into a spent, sloppy kiss. “Took such good care of me,” you mutter into his mouth, shivering while he takes the opportunity to carefully slide out of you. “Love you so much.”

In a few minutes, the two of you will have to stumble out of bed to the bathroom, clean up and truly recover. But right now, Sam’s smile against your lips warms your chest enough to forget about his cum dripping from your cunt. “Love you too.”
