Chapter Text
Stephen curses and squirms ineffectually where he’s trapped halfway through the wall. He probably shouldn’t have been training when he was already exhausted, but he’d been annoyed by his inability to fall asleep and agitated by an undercurrent of horniness that hadn’t even been touched by jerking off. He’d hoped a training session might burn off the right kind of energy, and there was value in training tired; enemies wouldn’t wait for them to get a good night’s sleep.
Apparently, however, Stephen had pushed it too far, because his concentration had slipped and instead of sliding through the narrow opening in one of the obstacle course’s walls, he’s thoroughly stuck with his upper body on one side and his lower body on the other side. Fortunately, the opening isn’t narrow enough to be dangerous, but he’s not going anywhere until he’s rested and recharged enough to try the spell again.
“At least it’s the middle of the night,” Stephen mutters to himself. The only thing that would make this worse is if one of the other Avengers found him in this humiliating position. Sighing, Stephen closes his eyes and tries to rest, despite his uncomfortable position.
With no way to track time, Stephen has no idea how long he’s been hanging there when he hears footsteps. “Hello?” he calls out hesitantly. He doesn’t really want to be found, but if it has to happen, maybe they can help him get loose. But whoever it is, they don’t answer, even as their footsteps come closer.
Eventually, it sounds like they’re right behind him, on the side of the wall with Stephen’s lower half, and the footsteps stop. “I’m… stuck,” Stephen admits. “It’ll be hours before I can get myself out. I could use a hand.”
Instead of an answer, the person behind him flips up the ends of Stephen’s tunic. He frowns. That’s hardly going to help. Then fingers hook into the waistband of his pants and pull them down, taking Stephen’s underwear with them. “Hey!” Stephen yelps. “What are you doing?!” Whoever it is, they leave his pants around his ankles, binding them together. Stephen flushes at the thought of the sight he must make, his bare ass hanging out of a wall. “Very funny,” he snaps. “Now pull my pants back up and get out, if you aren’t going to help.”
Two strong hands grip his ass cheeks and spread them open, exposing Stephen’s hole. His breath stops. He can’t find words. It has to be one of the Avengers back there. No one else has access to this room. One of the Avengers is doing this. “Stop,” Stephen says. His voice sounds weaker than he’d like, shock stealing some of his certainty. He gathers it together. “I don’t want you to touch me.”
One hand lets go, but only one. The click of a bottle opening seems to echo. Cold lube hits the top of the crease of Stephen’s ass and slides down over his hole. Fuck, this can’t be happening, Stephen thinks desperately. He thrashes, but the Avenger has no trouble avoiding his flailing legs. After a moment, something pushes down hard on the tangled pants around Stephen’s ankles—they’ve stepped on them, probably, pinning Stephen’s legs in place. “Please don’t,” Stephen says desperately, but a finger pushes into his ass anyway. He cries out, clenching his eyes shut against the violation. “Stop,” Stephen begs, even as the finger begins thrusting and twisting. Nobody but a doctor has ever touched him there, and this is the furthest possible thing from that distant, clinical touch.
The finger retreats briefly, only long enough for more lube to be applied before it pushes deep inside him again, spreading lube around his hole. Getting him ready, Stephen realizes in horror. “I don’t want this,” he grates out harshly. “I don’t want this.”
A second finger thrusts inside Stephen alongside the first. Together they crook, stroking hard over Stephen’s prostate. He shouts, a bolt of pleasure arching through him. Stephen has a moment to gasp for breath before the Avenger does it again, and again, rubbing Stephen’s prostate relentlessly until his heart is pounding and his cock is hard and throbbing. Then they pull out of Stephen and put a hand on his cock. “I can’t help that,” Stephen says breathlessly. “It doesn’t mean I want it.”
The Avenger strokes his cock briefly, as if to say, You may not want it, but you’re going to like it. Stephen clenches his eyes shut, expecting the fingers back inside him. Instead a much hotter, blunter touch nudges his hole.
“Condom!” Stephen gasps. “Please, at least use a condom.”
The Avenger doesn’t even pause, just pushes forward slowly, forcing Stephen’s hole to spread open for the fat, slick head of his cock. Stephen hangs his head, tears streaking his cheeks even as the aching heat of his hole stretching travels to his cock and makes it throb harder. His own body has betrayed him, not only allowing the invasion, but pulsing with pleasure because of it.
There’s a brief pause as Stephen’s hole closes around the flared cockhead. Maybe the Avenger needs a minute to get control of himself. Maybe he thinks he’s giving Stephen a minute to adjust. Either way, they’re suspended like that for a moment, Stephen’s hole fluttering around the cockhead inside him, his belly tight with dread—and something hotter, an involuntary curl of sensation that he refuses to name—as he waits for the rest.
And then the Avenger moves and Stephen groans as inch after inch of the Avenger’s shaft slides past the sensitive, aching ring of his hole. Whoever he is, he’s big, reaching much deeper than his fingers. Stephen pants helplessly, hands pressing futilely against his side of the wall as his ass is filled with the Avenger’s long, thick cock. It seems to go on forever, until Stephen is so stuffed with cock that he actually looks down to see if it’s distending his belly. It isn’t, of course, no one is big enough for that, but it feels like it should be. Stephen has never felt so utterly taken as he does now, his body nothing but a sleeve for the Avenger’s cock.
Finally the coarse texture of pubic hair presses into the cheeks of Stephen’s ass and the slide of the shaft into his hole stops. Stephen tries to catch his breath. He really does need a minute to adjust now. The Avenger puts a hand on Stephen’s cock again and he shouts, jerking, his hole clenching involuntarily around the Avenger. He lets go of Stephen, patting his hip as if in approval, and humiliation floods Stephen. Most men get soft during penetration, he knows, but he’d gotten harder, and the Avenger likes it.
The Avenger must be listening, because when Stephen’s breathing has calmed, he takes hold of Stephen’s hips with both hands and thrusts. Stephen shouts, the sudden withdrawal and hard drive back into his hole sending a shock through his body. There’s no more breaks, the Avenger thrusting again and again, pounding his cock into Stephen’s ass. Stephen wails and squirms, eyes wide, the sensations so intense that he can’t even process them, and then the Avenger gives him a sharp slap on the hip and the crack of pain abruptly translates everything else into pleasure. Stephen sobs as ecstasy floods him. It doesn’t matter anymore that he hadn’t wanted this, the Avenger is running Stephen’s body now, giving him a hole that eagerly welcomes his driving cock and a mind caught in a riptide of pleasure that allows no thoughts but, Good, so good, so full, so hot, so good.
Stephen rides the waves of pleasure that surge through him, ebbing somewhat with the withdrawal of the Avenger’s cock and cresting when that cock plunges back into him. Moans fill the air, the sounds of Stephen’s helpless rapture masking any noises the Avenger might be making as he fucks Stephen vigorously. Every now and then the Avenger repeats the slap on Stephen’s hip, and every time it seems to spike the intensity of Stephen’s pleasure. He starts to anticipate the strikes, breathlessly waiting for the surge in sensation and shouting with satisfaction when they land.
And then, along with the slap, the Avenger twists his hips as he thrusts, forcing Stephen’s stretched hole even wider and stirring his insides. Stephen’s eyes roll back in his head, and the Avenger does it again, a slap and a twisting thrust, his cock plowing Stephen’s body, and again, and Stephen shatters, orgasm tearing through him. His whole body clenches with the strength of it, ass closing tightly around the cock filling him. The Avenger stops thrusting, keeping his cock buried to the root inside of Stephen and letting the clenching of Stephen’s climax do the work.
Stephen is just starting to come down from his peak when the Avenger’s cock throbs and spurts inside of him. Hot jets of come flood Stephen’s ass and his own cock jerks, one last shock of pleasure triggered by the Avenger filling him that little bit more, marking him that little bit deeper.
Slowly, Stephen’s thoughts grow clearer. He hangs draped from his place halfway through the wall, his cock slowly softening, sweat dampening his skin. The Avenger behind him pulls out carefully, and Stephen can feel his hole gape and struggle to close. Shame overcomes Stephen. He feels used, a convenient hole, trapped as he is. Worse, he enjoyed it. It hadn’t even been hard for the Avenger to silence Stephen’s protests: from the moment he got a cock inside of him, Stephen had done nothing but moan and cry out in pleasure. He’d thought he was stronger than that. He’d survived hundreds of deaths at Dormammu’s hands and his resolve had never faltered. But while pain might be an old friend, apparently pleasure is Stephen’s enemy.
It’s over now, Stephen thinks. You can figure out how to protect against this weakness once you get out of this wall. His magic still feels drained, but once the Avenger is gone he can try.
But there’s no sound of footsteps retreating.
Stephen waits, but still nothing. Had he missed it? “You’ve had your fun,” he says, voice hoarse. From shouting with pleasure, Stephen thinks. He pushes the thought away. “Get out.”
More silence, long enough that Stephen starts to wonder if he really did miss the Avenger leaving. He’s just resolved himself to trying with his magic when a slick finger strokes the rim of his sore, stretched hole. Stephen’s breath catches as a shiver of pleasure goes through him. You don’t want this, he admonishes himself. He may have lost himself to sensation once, but he won’t, can’t, let it happen again.
The finger teasing his hole dips inside and presses him open. Stephen bites his lip against the noise that wants to escape and swallows hard when he feels a trickle of semen leak out of him. The Avenger uses his finger to scoop it up and press it back inside.
“Aren’t you done?” Stephen demands.
In answer, the Avenger presses his cock between the cheeks of Stephen’s ass. He’s half hard, and as he rubs himself against Stephen he swells further, clearly rapidly growing ready for round two. Fuck, Stephen thinks. He’s not ready for this. He needs time to think, to guard himself, but the Avenger isn’t giving him time. The thick cock grinding against him slides over his hole, teasing the sensitive skin and reminding Stephen’s body how good it had felt to be penetrated, filled, fucked.
You don’t want this, Stephen reminds himself, eyes fixed on the floor. He doesn’t bother trying to tell the Avenger; the man has more than demonstrated he doesn’t care what Stephen wants. No, the important thing right now is that Stephen remembers that he doesn’t want this. No matter how good it feels, he needs to remember that he doesn’t want a cock inside him, filling him with heat, claiming him and marking him.
Stephen swallows hard. You don’t want this, he thinks as the Avenger’s cock hardens against him. You don’t want this, he thinks as the Avenger drips more lube down the crease of Stephen’s ass, easing the way for his cock to slide between Stephen’s cheeks. You don’t want this, he thinks as the hot shaft teases his hole. You don’t want this, he thinks as the Avenger presses Stephen’s ass cheeks together around his cock and thrusts into the channel he makes.
The Avenger adds even more lube and his cock starts making a slick, obscene noise as he rocks it between the cheeks of Stephen’s ass. Stephen stares at the floor and tries not to think about how his hole is throbbing, about how much better that cock would feel buried inside him. You don’t want this, Stephen insists, even as the Avenger’s cockhead catches on Stephen’s hole and it flexes as if to tempt the Avenger inside. No, Stephen thinks as the Avenger pauses, as if considering an invitation, and then rubs the wet head of his cock against Stephen’s hole. You don’t want this, Stephen thinks, but his hole softens and gives way at the slightest touch of the Avenger’s cock.
The slide of the Avenger’s cock into Stephen is smoother and faster this time than the first, Stephen having been fucked open quite thoroughly, and damn it, it feels so good.
You don’t want this, Stephen thinks frantically, but the hot, heavy pressure of the cock filling him feels incredible. Pleasure radiates out from his ass, making his skin tingle and his nipples tighten and his cock stiffen. He clenches his jaw against the moans that want to escape. The Avenger’s hips press against Stephen, his cock fully buried. He holds there for a moment and Stephen braces himself for the pounding, overwhelming rhythm that had drowned his mind in pleasure.
But it doesn’t come. Instead, the Avenger pulls out, the withdrawal a shivering stroke of sensation, and pauses with Stephen’s hole barely clinging to his cockhead before thrusting smoothly back in. It’s almost like being penetrated for the first time, Stephen realizes dizzily. Every slow stroke feels like it’s opening Stephen’s hole all over again. Instead of giving way before the Avenger once, Stephen’s body surrenders to him over and over and over again.
The ecstasy of the cock moving inside him slides inexorably into Stephen’s thoughts, carrying with it the delicious satisfaction of giving way. It fills Stephen’s mind, pushing everything else out. I was supposed to remember something, Stephen thinks fuzzily, but then the Avenger thrusts into him again and all he can think about is how good it feels when his hole spreads wide.
Stephen forgets why he’s trying to keep quiet; a full throated moan of pleasure escapes him. Of course it does, the slow, steady strokes of the Avenger’s cock feel amazing. Stephen squirms, but the grip of the wall leaves him no room to push into the thrusts, and the pants tangled around his legs won’t let him spread them. All he can do is moan and take it.
The Avenger fucks Stephen relentlessly, opening him up again and again until Stephen is desperate to keep that cock inside him. He’s painfully aroused by how easily his hole swallows up the Avenger’s cock, but God, what good is that if he doesn’t get the deep pressure of being stuffed full to go with it?
The word slips from Stephen without thought. “Please,” he moans.
The Avenger doesn’t pause, just continues fucking Stephen, teasingly close to slipping free entirely before penetrating him all over again.
“Please,” Stephen moans again, squirming and clenching against the Avenger’s next withdrawal in a futile effort to keep him inside. “Please, fill me.”
On the next thrust, the Avenger stops with his cock buried deep inside Stephen.
“Yes,” Stephen gasps, ass clenching around the thick, hot shaft. “Yes, like that, please.”
The Avenger pulls out maybe halfway before driving back into Stephen, a short, hard punch of a stroke, and it’s perfect, it’s exactly what he needed, the glorious pressure of a cock filling him to the brim. Stephen moans, in satisfaction this time, and the Avenger must know it because he keeps going, hips rolling through brief withdrawals before plunging back into Stephen.
After so long riding the pleasure of being opened, Stephen has little stamina left. It doesn’t take much time at all before being fucked achingly full tips Stephen over the edge. His orgasm this time is less of a shock and more of a cresting wave, pleasure carrying him over the edge and down a long slope of ebbing satisfaction. Through it all the Avenger never stops fucking him, the strokes drawing out Stephen’s climax.
Once more Stephen slowly comes back to himself hanging from the wall, but this time there’s still a cock driving into him. His mind is clearer now, not overcome with lust and ecstasy, but despite that the shame he’d felt the first time just isn’t there. The cock inside him belongs there, and when the Avenger finally tightens his grip on Stephen’s hips and thrusts deep and comes, the liquid heat of semen spilling inside him only makes his belly tighten with arousal.
Stephen had thought the Avenger’s withdrawal left him gaping before, but that was nothing on the way his hole sags after the cock leaves him this time. A thread of embarrassment stirs, but refuses to take hold, not when the only person who can see what a wreck he is is the man who made him that way.
It’s quiet for a while. Stephen knows he’s not alone this time: the Avenger is stroking his lower back and the curve of his ass, an idle, proprietary sort of petting. There’s no doubt in Stephen’s mind that he intends to fuck Stephen again. Most men wouldn’t be able to go three times in quick succession, but all of the Avengers have better than average stamina, even the purely human members. If he was done, he’d have left.
What will another fuck like that do to me? Stephen wonders. He’d gone into the first filled with horror and come out of it shouting with pleasure. He’d gone into the second determined to remember he didn’t want it and ended up begging to be fucked full. You don’t want this feels like a lie now: some part of him does want it, wants it desperately. Where will he end up, if he starts with the knowledge that he’s going to love every second of it, whether he wants to or not?
Does the Avenger on the other side of the wall even know what he’s doing to Stephen? Is it better if he does, or if he doesn’t? Stephen wonders.
In the end, it doesn’t really matter. Whether the Avenger knows or not, when his cock has hardened once more he fills Stephen with it just the same.
Stephen had wondered if it might hurt, this time. After all, he’s been thoroughly fucked twice now, it would be normal to be sore. And he knows how to deal with pain. But when the Avenger’s cock sinks into him there’s only heat and pressure and shivering, gut-tightening pleasure. I must have been made for this, Stephen thinks. How else could he take so much cock without ever getting sore? Why else would the slide of a cock into his hole so quickly derail any other thoughts he could have?
This time the Avenger’s pace is neither the overwhelming hammering of the first nor the slow, recurring penetration of the second. Instead it’s a familiar, comfortable fuck, as if the Avenger is satisfied with Stephen’s limits and feels no need to push them. Maybe that should make the wash of pleasure weaker, easier to resist, but it doesn’t. Stephen is just as lost to the movement of a cock inside him as he was before.
Moaning softly, Stephen braces his forearms on his side of the wall and closes his eyes, his focus narrowing to the broad hands gripping his hips and the heat of the thick shaft thrusting into him. God, the stretch of it never stops sending a rush of satisfaction through him. Even after two rounds, Stephen still feels the way his body has to make room, to expand, and it’s so helplessly good.
Stephen rides the waves of pleasure, occasionally clenching his hole just to feel the Avenger’s cock stuffing him. I never want this to stop, he realizes hazily. Now that he’s had it, now that Stephen knows how perfect it feels to be fucked, how deeply his body is wired to respond to having a cock inside him, how could he ever give it up? I need this, Stephen thinks, and the thought only makes him moan louder at the next thrust.
“Don’t stop,” Stephen moans. The Avenger’s pace hasn’t slowed or faltered even once, but he can’t hold the words inside. “Don’t ever stop.”
The Avenger’s hands slide up from his hips to cradle his waist and then back down, ending with a quick squeeze, his hips slapping steadily against Stephen’s ass as he fucks him. A moment later he repeats the caress. Nothing else changes, but Stephen knows: this won’t end with Stephen’s extraction from the wall. The Avenger has no intention of letting Stephen go. The thought pulls another moan from Stephen, excitement sparking along his nerves. Will he learn who his partner is today? Or will they leave him here and find him again later?
Today, Stephen prays as the Avenger’s cock drives into him, thick and hot and perfect. He doesn’t want to wait and hope the Avenger doesn’t change his mind. He wants the certainty that that glorious cock will take him again and again and again.
As much as Stephen wants this to last forever, he can’t hold back the rising tide of his own pleasure. His cock is aching, dripping a near-constant stream of precome. If the Avenger touched him even once, Stephen is sure he’d come instantly, but he keeps his hands on Stephen’s hips. He wants Stephen to come on his cock like he had before, to bring him to completion solely from being fucked. Hours ago, Stephen wouldn’t have believed it possible, but now, moaning helplessly, his whole body throbbing with pleasure, ass aching deliciously, he knows that he will.
When the rush of his orgasm finally takes Stephen he squeezes hard around the Avenger’s cock and cries out in triumph when the Avenger comes, too, the wet heat of the Avenger’s come spurting into Stephen sweetening his own climax. Stephen’s heart is still pounding when the Avenger pulls out, and he can’t help the disappointed groan that escapes him.
And then the wall holding Stephen shivers and the edge pressed tightly around him starts to crumble.
