Notes: If you're familiar with the RANS, you have my sympathies. It looks hellish. If I've gotten anything mixed up, feel free to say so, but know that I will probably just nod and smile politely.
simmysim is the reason this exists as well as the reason it was completed.
Reed has found that he deals better with isolation than most. Not to say that he enjoys being imprisoned in a small, dark room in an unknown location by an unbalanced madman, but the actual isolation aspect, the part that's supposed to drive him insane, seems to affect him a lot less than it does the various friends he's been imprisoned with.
But he's never seen anyone take it as bad as Tony Stark.
It's been nearly two weeks, which wouldn't seem quite as long if they were actually being put to some use, if they were being spoken to, if anyone had explained why they were here, but that isn't the case. Two weeks in a small, dark room with little food and no purpose feels close to a lifetime. Reed is sure there are at least two teams of superheroes looking for them, no matter the odds. He tells himself this, and it helps him keep his wits about him. He tells Tony this, and Tony has what Reed has come to recognize as some kind of nervous fit.
"It's been so long, what if something's happened to them? It's too bad out there, it shouldn't take them this long, as soon as my communications went down they would have started looking, but they're not here. They must be hurt, because they were looking for us, because I got us fucking captured..."
Reed is honestly concerned, he is; Tony is his friend and he is obviously distraught. But he's heard the same basic speech once every thirty minutes for the last several days, and he is yet to land upon an appropriate facial expression that doesn't seem to cause Tony more distress, so he sits next to him against the wall of the tiny, windowless dungeon, stares across the room, and pats him reassuringly on the shoulder.
It's not surprising that isolation affects Tony as deeply as it does. He's a social creature, and has been since Reed met him, when Tony couldn't have been more than fourteen. Hanging around in his father's office, introducing himself, shaking the hands of Howard's business partners. Boldly asking Reed for a detailed explanation of the presentation he was giving to the Stark Enterprises board of directors, actually challenging him on his conclusions, and looking genuinely impressed and somewhat admiring when Reed proved him wrong. He'd been a good kid. He's a good man now. He just obviously doesn't handle pressure very well.
Noticing that Tony has fallen silent, Reed turns to look at him, and clears his throat, feeling obligated to fill the gap. "There's no point in worrying about those things while we have no control over them." Which is true, if not always comforting. But apparently it's the wrong thing to say, because Tony shakes his head miserably, pressing the heels of his hands into his eyes.
It's not that Reed is uncomfortable with emotion, it's just that he doesn't know what to do - and likes to think that few people really would - when a friend is breaking down like this, in a way he's never experienced himself. He looks back at the far wall, but squeezes Tony's shoulder firmly. "I wish... I could help." He really, really does.
Tony's hand comes up to cover Reed's, and before Reed has another chance to speak, perhaps to apologize, his fingers are abruptly at Tony's lips, middle and pointer sucked into wet, wet and warm. Reed keeps his eyes on the wall.
He hears Tony's breathing pick up as soon as it becomes clear that Reed isn't pulling away. He's not moving, but he's not rejecting him either. He wants to turn, wants to find out what Tony's face looks like, whether he's looking at Reed or has his eyes closed, but Reed isn't quite clear on the proper procedure here, and it's taking him longer than normal to formulate a plan of action.
One of Tony's hands holds Reed's delicately, the other wraps loosely around his wrist, and a very practiced tongue plays around Reed's fingertips. Tony is panting noisily through his nose, holding his breath when he sucks the fingers in, releasing it shakily when he pulls back. It's the whimper that finally makes Reed turn his head.
Tony's eyes had been closed, but they open immediately at the movement, staring at Reed, tongue and lips not missing a beat. There's something... sad, in his eyes, something desperate and longing; Reed's never seen anything like it. He watches, for a moment, gaze fixed on Tony's lips, on his fingers disappearing between them, before speaking.
"Is this helping?"
Tony pulls Reed's fingers free, hand leaving his wrist in favour of his neck, clutching hopefully. "Please."
Reed nods, reaching out to stroke Tony's cheek, rough with days worth of stubble, and watching as his breath hitches. He has to admit that it's... appealing. Tony's charm isn't something that can be turned off, even here, and Reed finds himself pulled in almost instantly. It would be cruel to see trust like this and not acknowledge it, not reciprocate. But it can't be that simple.
His mind strays to the world outside this room, starts running the numbers, as it always does. Every minute that passes without the cavalry calling is making rescue less likely, and while he wouldn't say it out loud - not with Tony present, at any rate - he's slowly being forced to consider the fact that the world outside this room might just be a thing of the past for them. It hurts to think of Susan, it hurts so much he finds he can sometimes understand Tony's utter desperation and panic, and so he doesn't think of her, when he can help it. Sue is out there and all Reed can do is hope that she's safe, and just exist in this box, as well as he can... And give comfort to a friend who needs it.
Comfort. Because that's what it is. Necessary comfort, for Tony... For both of them. "Tony." He murmurs, not sure which emotion he was aiming for.
"Reed-" Tony starts, but cuts himself off when he lunges forward, pressing their lips together roughly.
Tony kisses the way anyone who knows him would expect; with all of his being, open and thorough and aiming to please, lips parting eagerly at the touch of Reed's tongue, utterly compliant. Reed threads his fingers through Tony's hair, taking control of the kiss, eliciting a soft moan. He's shaking with tension already, aching for contact, sliding into Reed's lap to straddle his thighs as soon as Reed snakes an arm around Tony's waist.
His underarmor is smooth and warm, shifting with his muscles. Reed slides his hand down, feeling the ridges of Tony's spine through the malleable golden sheath, then back up, to his neck, fingers playing at the line where skin meets metal. Reed would give almost anything for the opportunity to study Tony's physiology, so foreign and so ludicrously advanced... He groans, pressing Tony closer.
Breaking the kiss with a gasp, Tony tips his head back, rocking his hips, and Reed takes the opportunity to slide the tip of his tongue along the ridge of gold on his throat. It doesn't taste like metal, or much of anything, but it's smooth and - "God, Tony," he mutters against the man's neck as the metal seeps back into his skin, exposing him slowly beneath Reed's hands and lips. Flesh feels odd in comparison, more friction and more heat, a little dampness as his hand travels down Tony's back again, this time completing the journey, cupping his ass and grinding him forward against Reed's stomach.
Tony shudders at even that slight contact, his fingers tightening on Reed's shoulders as he gasps to the ceiling. He's desperate, frantic. This won't last long if it's up to him.
Reed gently pries Tony's hands from him and pulls off his own shirt. Reaching around Tony, he spreads it out on the cold stone floor, smoothing it before finally wrapping his arms securely around Tony again, lifting him, and laying him onto his back.
Reed watches Tony settle comfortably on his shirt, completely relaxed with his own nudity, spreading his legs for Reed to kneel between them. His body is humming with tension, and he opens his mouth eagerly when two of Reed's fingers press against his lips. He sucks with the same enthusiasm as before, letting out a soft whine when Reed pulls away.
"Do you know the Reynolds-averaged Navier Stokes equations?"
Tony looks completely thrown by the question, blinking three times, mouth gaping.
Reed sighs, bringing his hand between Tony's thighs and pressing one finger against his opening. Tony takes a sharp breath, eyes shutting, question forgotten. "The equation for a stationary incompressible flow of Newtonian fluid. Do you know it?" Reed asks, playing both fingers around his entrance now, not pushing in. If anything can distract him enough to keep an orgasm at bay, the RANS will.
"I-" Tony swallows, blinking again. "Yeah."
"What is it?" He presses the fingers inside, slowly, Tony tensing and shuddering at the intrusion.
"You want-" He breaks off as Reed raises his eyebrows, stilling his fingers pointedly. Tony shakes his head as if to clear it, inhaling shakily. "It's uh… rho times partial derivative u… Oh..." It trails off into a moan as Reed starts pushing again, twisting his fingers against the resistance. "… u-bar-j u-bar-i, over partial - fuck, Reed - partial derivative x-j."
Reed smiles, fingers reaching the limit then stretching to rub full on his prostate. "Keep going." He says softly as Tony bucks and moans. "Equals..." He prompts.
Tony stares at him, biting his lip, whimpering softly before speaking again. " E-equals..." He stutters, tipping his head back, breaking the eye contact, hips twitching each time Reed crooks his fingers, stroking. "Rho f-bar-i plus..." He swallows, brows creasing, hips stilling as he concentrates. "Plus..." He looks down at Reed, who pulls his fingers back until they're almost out, motionless. "Reed." Imploring eyes, wide and bright, Reed finds himself wanting to look away, but he smiles instead.
"Plus the derivative with respect to the partial derivative of x-j."
Tony nods, breathing a little harder. "Yeah. Yeah, times," A sharp gasp as Reed pushes the fingers back in, this time with a third joining them. "Negative p-bar delta-i-j - Christ, yes, there, that's - plus- plus mu times partial derivative u-bar-i over partial derivative x-j-" He breaks off with a cry, hips rolling jerkily as Reed's fingers stretch again, deeper inside him. Stroking Tony's shaking thigh with his free hand, he pushes a fourth finger into that clenching heat, stretching it to meet the others, filling him completely. Tony doesn't seem able to speak, mouth open, panting, moaning.
He's obviously ready, desperate, starved for it, and Reed is not trying to be cruel, but he feels compelled... "Finish it." He whispers, surprised at the hoarseness of his own voice, even moreso at the shiver that runs down his spine when Tony nods, continuing the equation with a trembling voice.
"Plus partial derivative u-bar-j..." A long pause where he blinks, futilely tries to stop his hips from rolling with Reed's hand. "Over partial derivative x-i. Minus...?" He looks at Reed again for help.
Reed nods. "That's right." His mouth feels drier than expected. His hand abandons Tony's thigh in favour of working his own pants down, enough to free his erection.
"Minus rho u-prime-i-u-prime-j-bar." He sounds triumphant when he finishes, proud, biting his lip and offering Reed a small grin. Reed leans over him, bracing a hand on the floor by Tony's head.
"Good," He breathes, planting a quick, claiming kiss on the smirking mouth. "That's good, Tony." He kisses him again as his fingers ease out of Tony's body, muffling the whine it causes. He positions himself at Tony's entrance and pauses, letting Tony squirm, wrap his legs around Reed's waist, and arch his back in anticipation.
Reed pushes in slowly, not wanting to cause damage, knowing how easy it would be to hurt him. Tony's discomfort shows, brows knitted together, breathing tight and fast. But when Reed stops to give him time to adjust, blue eyes fly open, thighs squeeze on his waist and he shakes his head, "Don't.. Reed, don't stop." The desperation is back, eyes wild and pleading; he needs this. Reed nods and keeps moving.
Tony is unguarded, every emotion and every sensation broadcasted clearly on his face. He whimpers at every inch gained, gritting his teeth and hissing when it's too much; moaning and begging silently with wide, beseeching eyes when it's not enough. Reed hopes his own face returns some of that openness, but that's one of the few areas where Tony has always outperformed him.
He's pulled into a kiss as soon as he's in to the hilt, Tony's hands on his face, his shoulders, in his hair. It's Reed who breaks the contact, pushing Tony's hands down, holding them to the floor on either side of his head as Reed stretches back, pulling out carefully as he does so. This angle is a lot more satisfying, he notes as he rolls his hips and watches pleasure bloom across Tony's face, patches of color visible on his cheeks even in the dim light provided by the weak, bare bulb over the door.
He's impossible to deny; his back arches insistently, intoxicating sounds escaping his lips at every shift of their bodies. Reed finds himself falling quickly into a demanding pace and yet Tony still asks for, "More, please, more."
Reed smiles to himself, coming to a full stop and waiting for Tony's eyes to meet his before stretching, slowly, inside him, reaching deeper than Tony could have expected, opening him wider. Tony's mouth is slack, breathing stuttered and fast, groaning blissfully in surprise. Reed might not have Tony's... extensive experience in these matters, but he can bet Tony's never made that plea and actually gotten it before.
"Reed, Jesus Christ," With unexpected strength, Tony wrenches his hands free and surges up, arms locking around Reed's neck and giving Reed little choice but to sit back on his heels, pulling Tony into his lap. His hands abandon the floor to wrap around Tony's back tightly. "Jesus... Fucking Christ, that's amazing." He moans against Reed's cheek, hips starting to move.
If Reed's earlier rhythm was rough, Tony's is downright violent. He's held tight against Reed's chest, but his thighs are tense, rocking him in Reed's lap, raising and lowering in the few inches Reed's hold is allowing him. Reed distantly acknowledges the possibility that he may have to shrink again if he really wants to avoid hurting Tony, but it's difficult to afford much consideration to any thoughts besides hot and tight and Tony.
Tony is practically wailing in his ear when he feels something smooth, something harder than skin, against his chest. He loosens his hold, letting Tony lean back, and watches as Tony spreads the underarmor across his chest from ribs to throat.
"You-" Reed chokes out, glancing up long enough to see Tony smiling lopsidedly down at him, before his eyes are pulled back to the glinting gold, transfixed.
"I liked..." He swallows hard, groaning, grinding himself down and losing his voice for a moment. "... the way you looked at it, before."
Reed licks his lips, leaning in and placing an open-mouthed kiss at the edge of gold on Tony's neck, tasting sweat on his skin and feeling the smooth metal under his lips. One arm leaves Tony's back, the other stretching to compensate as Reed's free hand runs down his side, thumb sliding over metal, fingers over flesh. Tony echoes his moan, hips more just rolling now than lifting, grip on Reed's shoulders tightening.
Reed licks a line across Tony's gold-clad clavicle, dipping his head, pressing a kiss in the center of his chest, and feels Tony's thighs stiffen, his back go rigid.
"Reed--" He cries out, strangled, exhausted as he comes, pulling the sheath back into his skin. Reed's lips touch moist flesh the moment Tony's clenching wrings out his own orgasm. They rock together, panting, riding it out until fatigue forces them to still.
It's five minutes before Tony shifts, sliding from Reed's lap and sitting somewhat limply on the floor. Reed pulls his pants back up, dusts off his shirt and pulls it over his head, while Tony covers himself in underarmor once again. Moving to the corner of the room, Reed sits with his legs in front of him and motions for Tony to follow.
Reed lets him lay his head in his lap, curled into a ball on the floor. He strokes Tony's hair softly, hoping that tonight, Tony might actually sleep. He barely hears the words, muffled against his hip. "I hope they're OK."
Reed nods, blinking hard, wetness gathering in the corners of his eyes for the first time since they were thrown in here.
All they can do is wait.
