Philosopher's Stone

Summary:

Dew's in over his head; Mountain isn’t small, in any sense of the word. This isn’t news. But now, faced with the reality of taking his knot- which Mountain is so desperate for someone to do, because nobody else has wanted to try to do it- it feels intimidating. A cold light of morning realization.

“Not like this,” Mountain’s hand grabs one of Dew’s wrists, which he pins above his head, and with that to steady him, does the same with the other. He grinds against Dew again, slow and filthy as Dew’s eyes unfocus. “Not like this,” Mountain repeats. “You’ve never felt something like this before.”

Work Text:

Dew’s in over his head. 

Listen, he was dimly aware of this when he agreed, but he gets stupid when he’s horny. So sue him.

Here’s the thing: Mountain had been buried in him, Dew’s legs above his shoulders, and it was just so deep, every single thrust was startling in its intensity. Dewdrop was, to put it politely, out of his fucking mind. So when Mountain’s hips started snapping faster and he began begging Will you take my knot sometime? Would you ever? Would you let me?, he does what any self-respecting ghoul would do, and cums immediately right onto his own face. Followed by, naturally, telling Mountain over and over again when they’ve both collapsed into each other, hot and sticky, that of course he’ll take his knot. Next time, next time he’d take whatever Mountain wanted to give him. Mountain had continued swiping around Dew’s hole, pushing his leaking cum back inside and asking Really? You’d do that for me? and Dew had said without hesitation I’ll take it all.

Like he said. He gets stupid when he’s horny. 

He’s been accused of being overconfident before. It isn’t an incorrect assumption, and usually, a solid 90% of the time he’d say, it works out okay.

But Mountain is much, much bigger than him, and he’s starting to wonder if this isn’t one of those 10% times.

Mountain’s bullying him towards the bed, hands roving all over and Dewdrop lets himself be pushed. He ends up seated on the edge, where Mountain pushes his legs apart so he can kneel in between them, and mouth at the outline of Dew’s hardening cock through his trousers. Dew runs a hand through his hair and feels a little insane. 

“I can feel how hot your mouth is,” he breathes, and Mountain raises his head, grinning.

“Yeah? You want it?” Dew responds by grabbing the back of Mountain's neck and tilting his head in for a kiss. Mountain makes it dirty immediately, much to Dew’s immense satisfaction. 

There’s a desperation in him tonight that isn’t usually present. He reaches to rub his hands over Dew’s chest, sliding them onto his shoulders, then up to hold Dew’s face, licking into his mouth, possessive, while Dew twists his fingers in whatever hair he can grab at the nape of Mountain’s neck. When Dew is breathless and dizzy with it, he pulls his head back, and Mountain attaches his mouth to his neck.

He learned early on that it’s a weak spot for him and has abused that knowledge to the highest degree ever since. 

Dew makes an embarrassing noise as a series of wet, open mouthed kisses trail down the side, followed by a tongue licking a hot stripe back up to his ear, sucking the lobe into his mouth, scraping it with his teeth when he pulls back to begin sucking at Dew’s neck. He’s going to be so bruised there, Unholy Father is he ever. And he just doesn’t stop, nipping at his jaw, sucking at the pulse. Dew feels high, already.

“Give me your mouth?” Dew pleads. “For a bit, suck me for a little bit.” Mountain growls in his ear and his hands start unbuckling and unzipping Dew’s pants with no hesitation, rough like he’d tear them off if Dew gave him permission. He slows down some when he pulls Dew’s cock out, and Dew scrambles to grab the blankets, bracing himself. 

“Gonna drain this dry tonight, you know that?” Mountain grins, stroking up down to watch him squirm where he’s sitting. Then he’s holding eye contact with Dew while he licks up the shaft, getting it absolutely covered in spit before sucking on the head. Dew’s face goes slack, and his toes curl. His mouth is just so warm, the large hand wrapped around his cock squeezing just right. His other hand, heavy on Dew’s thigh, looks so large. He catalogs these details as best he can with his attention so scattered.

He half expected Mountain to tease a little, like he usually does, but his obvious enthusiasm for the night’s event has him hollowing his cheeks and- if Dew had a soul, he’d be trying to suck it out of his dick. It’s a lot all at once, and after a few minutes of relentless pleasure, Dew’s making noise and stroking Mountain’s face to get his attention.

“Hang on,” Dew huffs out. “You gotta- slow down, sorry-” He pulls off with an obscene pop, wiping his mouth on the back of his hand and Dew groans. 

“I could get you off first,” Mountain offers, running his hands up and down Dew’s thighs. “Might relax you? C’mon, we both know you’re good for a second round.”

Relax. Well. That’s the task at hand, isn’t it. He considers it for a moment. A very brief moment, because Mountain is standing up and shoving his pants down and it’s probably best if he doesn’t give himself time to think or hesitate.

“Take off your clothes, Dew,” says Mountain, and his voice is a little lower. Less lighthearted than it had been before he’d sucked him. For all the listening he does not do, Dewdrop follows orders extremely well when they’re given in the correct setting. He peels his shirt off first, making a show of exposing his skin, and then shucks his pants, balling it all onto the floor. Mountain’s watching, cock in hand, stroking. 

“Will you come on my knot?” he asks, and he almost sounds a little shy. “I really want to feel you squeezing it.” Dew does what he always does: jump into the deep end and assume he’ll figure out the swimming part as he goes. 

“Hurry up and get it in.”

Mountain is flashing that beatific smile, the genuine one that Dew knows he sees more of than anyone else, and yes, he’s petty enough to notice and clothe himself in it. Mountain climbs onto the bed and grabs around Dew’s torso and pulls him close. With ease. Like Dew weighs nothing. He’s kissing Dew again, even as he moves to bracket him, holding himself on top and grinding his pelvis against Dew’s. He feels so very small under him like this; it’s one of his favourite things about their little trysts, the way Mountain makes him feel so thoroughly owned. 

“M’gonna stuff you so full,” Mountain breathes against his neck, eliciting a shiver both from the breath and the words themselves. “You’ll feel me for days.”

It makes him feel owned, yes, but tonight it also makes him feel a little anxious. 

Mountain isn’t small, in any sense of the word. This isn’t news. But now, faced with the reality of taking his knot- which Mountain is so desperate for someone to do, because nobody else has wanted to try to do it- it feels intimidating. A cold light of morning realization.

“I already do,” Dewdrop tells him, reaching to grab his arms, trail his hands over his shoulders, to touch any part of him he can. 

“Not like this,” Mountain’s hand grabs one of Dew’s wrists, which he pins above his head, and with that to steady him, does the same with the other. He grinds against Dew again, slow and filthy as Dew’s eyes unfocus. “Not like this,” Mountain repeats. “You’ve never felt something like this before.”

He’s anxious. He’s actually anxious. So he does the appropriate thing, which of course, is to goad.

“Stop making me wait,” Dew nips at Mountain’s plush lower lip. “You all talk?” 

Mountain has him flipped onto his stomach before he knows it, before his mind can register being tossed around as easy as shifting a pillow. Hands on his hips, Mountain hauls Dew to his hands and knees, and leaves only for a moment to grab the bottle of lube on the nightstand he’d set out. Dew inhales slowly, trying to calm himself when he hears the cap pop open, and the wet sounds of a substantial amount being squirted into Mountain’s hand. One hand grips his ass, and the other-

Mountain slides the first finger into him in one go, and oh was that nice. Dew hums, letting his eyes drift shut as he works it in and out, gentle, but deliberate. This is familiar. This feels good.

“How’s that?” Mountain asks, voice soft.

“It’s good,” Dew sighs. And then, because he cannot for the life of himself shut up, “Is that all?” He hears Mountain chuckle, a little incredulous. 

“Is that all,” he parrots back, and then the hand on his ass is pushing his shoulders down, leaving him face down, ass up, exposed. Mountain’s second finger is pushed in alongside, and it isn’t like Dew can’t take that, but it’s, well. It’s a faster prep than they usually do. He bites his lip, and when the long fingers press and stroke inside of him, it triggers such a diffuse, achy pleasure that Dew can’t hold back a low moan. 

“That’s it, yeah,” he says, and the nerves he feels ease off again. He strokes and strokes and Dew’s hips shift to press back and meet his fingers, and when Mountain adds a third, he’s almost convinced himself that there’s nothing to be nervous about. He’s slowed down some, obviously remembering that this isn’t something he can rush Dew through tonight, but it’s still so obvious how he’s holding back, how much active concentration it’s taking not to bury himself in Dew quick as he likes. 

His fingers are gone, and the lube bottle is being opened again, the slick sounds of Mountain stroking himself wetly filling the room. 

Dew is doing fine, he totally is, right up until he feels the thick, blunt head of Mountain’s cock slide up and down over his hole, and Mountain growls,

“You’re so slight. You’re going to look so-” he pushes in and breaks off into a groan, and Dew’s hands scrabble to grab blankets as he gasps, “small. You’re going to look so small, all stretched around me.”

Dew’s panting by the time he bottoms out, eyes shut. It’s a shame he couldn’t shut his ears. Mountain feels huge inside of him, like he always does, but Dew’s never had to think about anything more, before, and as he pauses to give him some time to adjust, the reality of what he’s agreed to begins to gnaw at him. Mountain drapes himself over Dew, chest pressing to his back. Unholy Father, he’s so large above him. Could fold him in half and break him and-

“You good?” Mountain’s whispers break through the sound of their panting. “Can I move?”

“You waiting for someone to hold your hand?” 

“There’s my little spitfire.” Dew can hear the smile in his voice as he begins pulling out inch by careful inch, and he takes a deep, steadying breath, right before Mountain begins rutting into him and his mind goes blank.

He’s got his hands gripping Dew’s hips, large and tight where they grasp, pulling Dew back to meet him with every thrust, and Dew just has to take it. He’s pushed and pulled like it’s nothing, like he’s a little toy. His body’s being rocked with every thrust, and he keeps his eyes shut, mouth closed while he just focuses on breathing harshly in and out of his nose. He’s done this plenty of times before, he doesn’t need to worry.

Mountain slams in unexpectedly hard and it sends a jolt through Dew that isn’t entirely pleasurable, though Mountain moans with it even as it has Dew gripping the bedsheets and gritting his teeth. 

“Fuck, that’s good,” Mountain tells him, doing it again. “You’re so tight, Dew.”

“Yeah,” Dew manages stupidly, while Mountain keeps rocking into him with that same force. It’s so deep, he’s so deep, he can’t stop clenching around him. 

“How do I feel? Huh?” Mountain brings a hand down on Dew’s ass with a firm slap, and Dew startles.

Huge,” Dew says, fumbling to get a hand under himself so he can stroke his cock a little.

“Just wait,” Mountain says, and then he’s fucking into Dew like it’s his job, hard and fast and so, so much. 

He gets lost in it, the drag of Mountain’s cock, the flare of pleasure when it hits his prostate just right. He pants into the bed sheets, lets Mountain’s hands push, pull, press him further into the mattress any way he sees fit. It’s always a lot, always overwhelming in some way, but they’re both carried away with it tonight. If nothing else registers in Dew’s fucked out brain, that does. 

A hand fists in Dew’s hair and yanks, Mountain’s thrusts settling into a grind while Dew yelps.

“Dew,” Satanas, he sounds so out of breath, so wild, “can you feel that?”

Dew does. He can. He can feel something swelling where he’s grinding, and it’s-it’s huge, it’s not even fully- it’s-

Head wrenched back far enough Mountain can stare into his face while he looms over him, imposing and intense, Dew blinks, finding himself beginning to tremble.

“That’s…” he starts, and trails off. He knows what it is.

“Lube,” Dew begs then, body tense. “More lube, can you-”

Mountain keeps grinding while he adds more to the mess, and the anxiety has settled into Dew truly, now. He’s trying to breathe, to will himself to relax, but even his hand on his cock isn’t a good distraction, and mortifyingly, he’s starting to go a little soft, no matter how well he pulls at himself. All the while, he just hears Mountain telling him how huge he’s going to feel, how much he wants to see Dew’s little body shake and he’s edging closer and closer to hysteria.

“Dew, you’re really tight,” comes the voice above him. “You’re, ah, relax for me, so you can take this, you want it-”

He can’t take it. He realizes it, but doesn’t want to stop, but fuck even from what little he feels, he knows it’s going to be so much, too much, but he doesn’t want to stop. His heart is going a mile a minute, nervy, and he’s given up trying to jerk himself off. He’s limp. It’s embarrassing.

Mountain stops.

“Dew.”

“C’mon,” Dew pushes back against him, “c’mon, keep going.” Mountain’s hands hold him still.

“Turn over.”

“It’s good like this,” Dew says. He really doesn’t want Mountain to see his face. 

It’s a horrible feeling when he pulls out, but Dew doesn’t have the leverage to keep him in, not with the way his hips are being gripped. Oh, this is embarrassing. Worse, when he feels himself clench around nothing and Mountain groans at the sight.

“Turn over, now. Or I’ll do it for you.” Dew hesitates just long enough where Mountain makes good on the threat, and Dew finds himself on his back, eyes wide, face burning, his narrow chest rising and falling with every rabbit-quick breath. From above, Mountain is catching his breath, sitting back on his haunches and staring at Dew, concerned.

“What’s going on?”

“Nothing, now,” Dew glares, the self-consciousness propelling him to newer, greater heights of unnecessary rudeness. 

“Dew-”

“Are you fucking me or not?”

It shuts Mountain up, at least. Unfortunately, that’s all it does. It does not make Dew feel better about anything, it doesn’t get his cock hard again, and it doesn’t distract from how intensely Mountain is looking at him. They stare at each other, and Dew decides that if it’s not happening, he’s not particularly interested in looking like a fool by staying. He pushes himself up to sitting, and is about to make some other chippy remark to protect his bruised ego, when Mountain reaches out to run a hand up and down his thigh. A bit like calming a startled animal, which Dew decides to take as very condescending, instead of the soothing gesture it’s meant as, because he can.

“Why didn’t you say something?”

“About what?”

“That you’re.” Mountain keeps stroking his thigh, and it’s clear he’s trying to suss out the best way to phrase this, “Nervous?” A one word accusation isn’t much for Dew to deflect, especially when it’s true. He shrugs, looks off to the side, and feels violently awkward. There’s a beat of silence, and Dew is just about to jump out of his skin with how uncomfortable he feels, but Mountain lunges forward, a hand on the bed to support himself while he kisses Dew hard on the mouth. His head feels quieter, his attention focused just on the sensation. He’s so grateful for the momentary reprieve that he could kiss him, if, you know, he wasn’t already. 

“Do you want to stop?” Mountain asks as he pulls away, eyes searching.

“No.” Dew takes a deep breath and sighs, annoyed with himself. “I don’t.”

He really doesn’t. Truly. He feels foolish, though, and there are few things on this godblessed Earth that he hates more than feeling stupid. Performance anxiety isn’t really a thing for him. Awful that it should happen now, in this scenario. Should he have…practiced? The thought feels ridiculous to him, the idea that he’d be- doing something like that alone in his room. He probably could have warmed himself up before showing up, though, maybe that’s on him.

“I can hear you thinking,” Mountain tells him, and it jolts him so suddenly from his thoughts, he feels like he’s been drenched in ice water. Occasionally, he wonders if he can read his mind. Dew watches while he settles against the headboard, and fixes a pillow behind his back.

“If you want to,” Mountain offers, giving him a small smile that’s all open and easy affection, “you could come get in my lap. Or I can suck you off. Or anything else you want.”

Dew looks at his thighs, at the heavy cock jutting out (and fuck, that knot), at hands he knows are going to grope at every inch of him- of course he wants to. He hates that he’s nervous, but he wants to. Is this one of those jumping in and learning to swim later moments? Almost assuredly. He’s going to spend the next few days complaining miserably to Mountain about how sore he is, what an absolute brute he was. 

However…

“I’m gonna make it good for you,” he promises, kissing Dew slow and deep when Dew gets a leg over his lap. He reaches to grab Mountain’s cock so he can get them aligned, but his hand is knocked away. “Not yet,” he says against his mouth, running his hands up Dew’s chest, tangling in his long hair. Dew shivers at the feeling, his own hands coming up to grip Mountain’s shoulders.

“Don’t treat me like I’m an idiot,” he snaps at Mountain, for, truly, no particular reason. He ignores the comment, and slides his hand behind Dew’s neck, pulling it close so he can start mouthing at his throat. 

“Relax and let me make you feel good,” he whispers. He scrapes his teeth against soft skin without giving Dew the satisfaction of even a small bite, backing off to nip at his jawline once, and then continues placing wet, sucking kisses that he knows make Dew’s toes curl. 

“You’re off to a good start,” Dew huffs, and then whines when fingers loosely encircle his limp cock, toying with him. Fondling, really, no intent to the movement other than play around. It feels so nice, though, not as much stimulation as he wants, but enough to make his blood start racing hot and fast through inhuman veins again. 

It’s a slower process than he wants, but when he starts filling back out and Mountain grips him just tight enough to slide the foreskin up and down over the head achingly slowly- he’s back in it. Oh, is he ever. His cock looks small in that large hand. He feels Mountain smile against his neck, feels the long tongue drag up the side of his neck and lick teasingly at his earlobe before sucking it into his mouth. He lets out a little whine, the feeling lighting up the nerves in his back. 

“You’re gonna be so full of me, it’s going to feel so good,” he continues, and tickles the head of Dew’s cock for a quick second before bringing his hand behind Dew, stroking at his hole. “Right here.” He twitches, and for the briefest moment, the thick finger presses in just slightly, enough to suggest but not enough for satisfaction of any amount. “You wanna sit on it again?”

“Yeah, put it in.”

Mountain lets go of Dew’s hair and leans back, grabbing his cock and stroking it while Dew watches, taking in the sight of how he pleasures himself. Long, firm strokes from just above where the knot is still in the early stages of swelling, up to the head. 

He can’t help himself, he really can't. So he reaches down for Mountain’s cock and sneaks his hand just below his fist, curling his fingers around the knot and gives it a nice little squeeze. Mountain’s eyes roll back and his head thumps the headboard.

Oh,” Mountain moans, and it’s more of a reaction that Dew was expecting, and he can’t help but echo the sound. He repeats it, and Mountain’s hips twitch up into his hand. “That’s good.” 

‘C’mon, put it in. I want it.” He does, he just needs some help along the way. More help and patience than he was planning on. He hates asking for help, but the sound his hand was able to wrench from him was sinful- he can only imagine what noises he’ll tear from his throat if he’s able to get it inside and clench around him. When Mountain helps guide it back in, Dew sinks down immediately with a heavy exhale, takes him as far as he can and starts grinding, his hands rubbing on Mountain’s pectorals. The hand that isn’t fondling Dew’s balls comes to rest on his bony hip. 

“Take what you need, just like that,” Mountain tells him. When he finds an angle that hits his prostate just right, he lets out a low groan. Mountain grabs his neck and pulls him in for a kiss, immediately opening his mouth for Dew’s tongue. He pushes and pulls at Dew’s hips as he moves, guiding him along.

“That good?” Mountain asks in between the slide of Dew’s tongue against his. “That a good spot?” With one last gentle roll of his balls, he wraps long fingers around Dew’s cock, hard again and hot in his palm. Dew breathes uh huh, still running his hands all over the plane of Mountain’s chest as he rocks his hips. “You know how well I’m gonna hit that when I get all this in you?”

Dew can only imagine. He can feel where Mountain’s knot has started to swell back up again as he grinds. He adjusts himself and begins to bounce. The pace is slow, but the drag of it is delicious, made all the sweeter by the way his cock is being worked. Satan, it’s good like this.  Mountain’s smiling where he’s kissing Dew’s lips, his neck, and he lets himself get lost in it, and for the first time tonight, actually relaxes.

Up until Mountain pauses him, and puts an arm around his waist so Dew doesn’t move as he leans to grab the bottle of lube. The sound of it uncapping sobers him up. Mountain makes a small noise as he clenches. 

“If you don’t want this,” he starts but Dew cuts him off.

“I said I’d take it, didn’t I?” 

Mountain’s face sets into something serious, keen, but he doesn’t stop slicking up his fingers. Dew gives him a hard look even as his hands flex where they’re steadying himself on his shoulder. When it becomes clear that isn’t going to be near enough, he meets his eyes and takes a breath. 

“Look,” and there’s an edge of irritation in his voice that isn’t irritation at all, just poorly masked anxiety, “I want it. But, I need…” he struggles for the right phrasing.

“Tell me,” Mountain breathes, as he reaches behind and rubs a slicked finger right where he’s buried in Dew, whose mouth falls open. The feeling doesn’t help his word finding. The finger strokes and massages, and begins to press, testing, and as it does, a voice in the back of his mind starts yelling about how he already feels stretched- another finger? Could he even manage that?

“Make me take it.” Mountain keeps touching, and Dew can feel how his presses get more and more intentional. His cock jerks inside of him, and the intensity with which he’s looking at Dew does nothing to keep him relaxed. 

“Make you?” Mountain raises an eyebrow, but his pupils are blown dark and there’s no mistaking the way his cock is throbbing inside him.

"Push me. I'm too in my head," he admits. "I don't know. Talk me through it, or something." 

He feels Mountain start to grind up into him again, and- that finger, that fucking finger- pushes in alongside his cock, just barely, but it’s enough to make Dew hiss and tense all over. If Dew’s fingers digging into his shoulders hurt, and they almost certainly do, he doesn’t say a word. 

“Breathe for me,” Mountain tells him. Focusing, Dew draws in a long, steady breath through his nose, as steady as he can manage, and tries to keep his exhale from rushing out all at once when the finger presses in. He feels his cock jerk and bead with fluid, wrenching his left hand off of Mountain’s shoulder to pull at himself. “Good.” The finger backs off and returns to rubbing along his rim. “See? You can fit more.” He can’t help but laugh at that, a little unhinged.

He does this a few times, and Dew isn’t sure it feels any less intense with each attempt. He feels sweat prickling at his hairline, at the nape of his neck. Eventually Mountain adds a little more lube right onto his dick, and gets his hands on Dew’s hips. 

“Ride me.” Dew starts to flex his thighs and bounce again, and Mountain’s got his feet anchored where he can push up to meet him. The slick, obscene sounds from where their bodies slot together cut through the room. 

He can feel it. 

He’s fucking down onto him in earnest, still jerking himself as he does. Every time it slides home, he feels the swelling knot pressing against him for just a moment, before he raises his hips and it slides away. 

“I need it,” Mountain whines, his hands tightening on Dew’s hips. “Need to be inside you.” 

“I promise you are,” Dew gasps, as Mountain pulls him down and holds him, his knot right there, huge. 

“All of it,” he says, and his voice is edging towards pleading. It makes Dew’s stomach twist to hear that tone paired with how he keeps grinding and pushing. “Need all of it inside you, need to feel you cumming on it. Can I take you on your back?”

Dew lets himself be laid down, carefully so he doesn’t slip out. He tries to ignore his shaking when Mountain hooks a leg over his shoulders, but when he pulls out and begins a slow press in, he loses it. He grabs at the forearm Mountains propping himself up with hard enough his knuckles start to go white, his other hand scrabbling for purchase in the blankets. 

“Oh fuck, hang on, hang on,” he croaks, and the panic is creeping back now, more pronounced with every hitch forwards and back Mountain’s hips make, each one more insistent. The pressure his knot’s putting on his entrance is making him feel edgy again. From this angle, every thrust Mountain gives him hits directly into that sweet spot. It’s so good he could cry.

“You have to relax for me,” Mountain says, and kisses him full on the mouth. He wastes no time licking in when Dew’s lips part for him, and swallowing the distressed little moans he starts making when his thrusts get harder. 

“I can’t- ah, shit, you’re-” Dew’s brows are knitted together, the muscles in his thighs shaking. “I don’t know how-”

“Let me in,” Mountain mouths against his jaw, and licks his cheek. “Let me in, you want me in. You want me in you.”

Hysteria bubbles up in his chest, which feels too heavy, too tight. Willing himself to breathe, he tries to let the tension bleed from his body with every exhale. The death grip he has on Mountain’s arm and the bedsheets stay, but his hips and thighs relax. It doesn’t feel substantial to him, but it must be.

There we go,” he groans, “like that. That’s it.” 

Encouraged, he sucks in another deep breath and focuses on trying to let go. It’s not an easy thing to do, with his body rocked with every thrust and pleasure blooming out from deep inside, the anxiety that only makes him want to clench further. But- no, okay, he- he can probably do this. His dick’s staying hard, at any rate. He focuses on keeping his breathing as intentional and steady as he possibly can, but the sounds Mountain has started to make are going to trip him up. He’s pausing with every thrust to push hard for a moment, closer and closer to popping it in before backing off, and Dew lets go of the sheets to get a hand on himself, his cock drooling out a large spurt of precum.

He has no leverage like this, with how Mountain is bent forward with his leg on his shoulder. There’s no pushing back, no pushing forwards. Just taking it. Just his body underneath Mountain’s larger one, while his thrusts speed up and Dew holds onto an arm like that’s going to be enough, somehow. Just taking it. That’s all he can do. Nothing else.

Mountain whimpers, a sad, needy sound followed by I’m gonna, I need to.

Dew panics. 

“Mountain, hey, hang on,” Dew gasps, and Mountain lets his leg drop from his shoulder, only to worm an arm behind his shoulders, grab a fistful of Dew’s hair with his other hand and simply hold him there. Hold him still, against him while Dew’s hands press against his chest. Dew starts to tremble, eyes shut tight. Pinned between the bed and his solid body, trying desperately to relax while Mountain’s panting against his neck, rambling, hips snapping forward insistently and it’s going to happen and he can’t stop it.

“Let me give it to you,” Mountain says, breathing hot against his skin. “Make you feel so good, get in so deep.”

“You are,” Dew wheezes. “It’s so much- I, fuck-” Mountain cuts him off by sucking on his neck viciously. 

“Gonna knot you,” Mountain tells him then, voice dark and gravelly. Dew feels it start bumping hard on his rim again and sliding in the littlest bit with every thrust. His knees instinctively try to close, pressing worthlessly into Mountain’s sides.

“I don’t know,” Dew manages, “I don’t think I can, I can’t,” and Mountain just holds him tighter.

“I need it, so bad. Can’t stop now.” He’s speaking directly into Dew’s ear, and it makes him shiver. “Let me in you, let me inside, fuck, you feel so good, Dew.” His words send pleasure zinging down his spine, and he’s helpless to stop himself from clenching at the words while his cock twitches from them. 

That’s what does it. Mountain makes a strangled noise and then shoves it in him all at once with a slick pop, and then keens as he starts to cum. He was right; Dew’s never felt anything like this before. 

It’s a good thing he’s holding Dew, because the sensation of the ever expanding knot inside him has him thrashing, mindless and unsure if he wants to get away or fuck himself on it further. It’s just so much pressure, he’s huge- Mountain is moaning uncontrollably while his cock jerks and he empties himself deep within, hips grinding forward the whole time.

“That’s it, Dew, Dew, you’re taking it, you’re fucking taking it-” he props himself up just enough to reach between their bodies to grab Dew’s cock. It isn’t a great angle, but it makes no difference- he’s barely started to pull at him when Dew loses it.

“Oh no,” Dew whines, his eyes rolling back as the hard strokes on his little cock combined with the knot pressing against him leave him with no choice other than to cum. The pleasure crests over him quicker than he can prepare for, like flash flooding; there’s no time for a deep breath, or to brace himself. It’s just suddenly there and he can’t stand it, intense and consuming ache blooming out and making him feel utterly overwhelmed.

His whole body goes tense, seizing, and he clamps down further on Mountain’s knot, yelling while his cock shoots over and over, drenching their stomachs, drooling out everything it has while Mountain keeps grinding into his prostate and coaxing more until the pleasure becomes so much he feels his lashes get damp. There’s no focus beyond the way Mountain is ruining him, how he’s changing him like this.

He shakes and shakes while a few hot tears leak out of the corners of his eyes. He doesn’t know what to do with his hands, still pressed against Mountain’s chest like he wants to push him off, or claw into his skin to keep him close.

“So good,” Mountain is praising him, voice frantic, a hand petting Dew’s hair like he’s a scared animal. They’re both out of their fucking minds right now.

“I can’t- no more,” Dew sobs, chest heaving. “Fuck, please.” He swallows hard, throat audibly clicking. He tightens for a second and it has Mountain groaning again and grinding his knot further, helpless. Dew lets out a high, reedy noise.

“Too much, it’s too much.”

“I’m sorry,” Mountain says, and despite his best efforts, his hips stutter forward again to Dew’s clear dismay. “You feel- you’re tight, I’m sorry, you feel so good.”

He’s pressing against all the right spots, but it’s a painful pleasure right now, and he can’t catch his breath. Mountain is still petting at him, biting his lip while he concentrates on keeping still. 

“Look at me,” Mountain urges, “please, look at me.”

Blearily, Dew opens his eyes and it takes a moment to focus on the face above him. Mountain looks wrecked and in disbelief, eyes wide, face flushed and sweaty along his hairline. 

“Dew,” Mountain says, and, Satan below, just hearing his name like that is going to make him shed a few more tears, the tone reverent and adoring. “Dew, you took it.” 

“Yeah.” Dew says, voice hoarse, still shaking like a leaf. “I said I would.” Mountain starts kissing his cheek, his jaw, gentle and slow. Silence settles over them while they collect themselves; for a long while it’s just the sound of breathing and the occasional sniffle from Dew. Unsurprisingly, Mountain breaks it first.

“You okay?” He sounds so shy, uncertain. “Was that…did you like it?”

“We’re doing it again,” Dew says. Clearly he’s out of his mind. “But you’re going to treat me like a goddamn king for the next week.”

“Anything,” Mountain says, completely stupified. 

Ever the opportunist, Dew begins coming up with a list of demands.
