"Dismissed." Steve Rogers' voice marked the end of the debriefing, and all the other members of the Avengers got up from wherever in the comm. room they had been sitting and made their way towards the exit. Tony Stark, still clad in his armour with only his face showing, rose from his chair, too.

"Not you, Iron Man. I'd like to have a word with you."

Tony stopped right in the doorway, turning around nonchalantly, almost theatrically, annoyance evident in his eyes. "Look, Cap, if this is about that one rocket, I have to say-"

"Just get in and close the door, Stark." Steve sounded almost tired, and Tony immediately obliged, for god-knows-what reason, without even complaining about the fact that his suit was in need of repairs and this was keeping him from that. Once the door swept to a close behind him, he regretted it immediately. The usually calm expression on Steve's face changed drastically until it was evident that the man was absolutely livid. Tony involuntarily took a step back when Captain America began to walk towards him, everything in his demeanour, from his steps to his posture, screamed wrath. But Tony Stark wasn't about o be subdued just by anger, and he regained his strength immediately. So when the accusation came, he was ready with a reply.

"You nearly killed Clint out there!"

"Correction: I just saved everyone out there." Tony's dry tone and crossed arms combined with the way he just looked at him, made Steve even more furious.

"Tony, we had a plan. You need to stick to it!" He was now so close to Tony that he almost touched him, but the other man didn't move an inch. The two eyed each other, Tony silently cursing he fact that he, for once, had to look up. "Yeah, I deviated from the plan, but what the hell! If our line had been broken like that, we would've been screwed like you won't believe."

"You're a loose cannon, I can't have loose cannons." Steve grasped Tony by the collar of his suit, lifting him a few inches off the ground.

"You're just angry that you can't control me. Well, here's an update for ya; nobody can." For some reason, those words got to Steve, and he slowly lowered Tony to the ground, letting go. He even took a step back. "I… No, that's not-"

"Prove it." Tony's low growl caught Steve unawares, and he almost had to ask him to repeat it.

"What to do you mean…?" Why was he looking at him like that? What was it in Tony's eyes just then that made Steve's throat go dry and his heartbeat slightly elevated.

"Prove it." Tony repeated, stepping forward and taking a hold of Steve's uniform, pulling him closer. "Submit to me." Steve was too shocked to do anything, and simply managed to splutter something neither of them understood. The other man's sudden paralysation urged Tony to take control, and so he did, pressing his lips against Steve's in a sudden and firm kiss. For once, JARVIS didn't need a voice command, and the suit practically removed itself, loosening in the right places and almost falling off of his limbs. Well, that was practical. He didn't know it could do that.

"Tony, this kind of thing, it isn't right." Steve said the moment his lips were released. Tony sighed and tilted his head, looking as though he was trying to carefully word some reply. Instead, he simply forced Steve to turn and pressed him against the wall, kissing him against, this time more forcefully, pressing their bodies together. Even Steve couldn't deny the reaction he had to the sudden stimulation, and he could feel himself harden, arousal beginning to course through his veins. But something rooted deep within him continued to scream that it wasn't right. He supposed it was something from his past, from the time he had grown up in. In this world, this time, here and now, this kind of activity was socially acceptable, or so he'd heard. His momentary doubt made Tony release his lips again, drawing away slightly.

"Listen, Steve, if you don't want –"

"No." Steve surprised even himself with his immediate reply, almost whispering out his words. "I do. Please." And immediately he felt those hot lips capturing his own, and that glorious body pressing on all the right places. Tony's tongue slowly entered Steve's mouth, and there was no battle, he won dominance immediately. Hands began to wander, Steve's wrapped around Tony's broad back, while Tony's wandered up to the nape of Steve's neck, beginning to remove the uniform. As soon as it was peeled down beneath his collarbone, the billionaire began to nibble along his neck and downwards, eliciting small gasps from the soldier.

Before either of them had really registered it, Steve's uniform was off, and lay discarded on the floor like Tony's suit. It was at that moment Tony decided to lie Steve down, pushing him to the floor. It would be easier this way, for both of them, and thus less painful for the soldier. Steve was at this point a moaning mess, writhing beneath Tony's ministrations, as the billionaire tweaked his nipples, let his hands run over his body, palmed against the erection Steve was sporting through his underwear, which was removed only moments later, Tony's own following suit. Then, he remembered that they, technically, hadn't locked the door.

"JARVIS, lock the door. No one is to enter." Tony managed to speak with a somewhat steady voice, whilst Steve began to moan loudly beneath him as he grinded their erections together, making the star spangled man writhe and mewl with each thrust. A loud click meant that the AI had done as ordered, and Tony, satisfied with that, turned to the man beneath him again.

"Steve, spread your legs." He ordered, and that made Rogers look up at him with hazy confusion in his eyes. "But, Tony, you can't mean – isn't it painful?" He sounded almost scared, and Tony immediately bent down to kiss him, a gentler, softer kiss this time, before whispering reassuringly into his ear.

"Don't worry, I know what I'm doing." He breathed against Steve's ear, making the hairs rise on the back of his neck. "Ooh, Tony…." He moaned, and his legs fell apart, baring him completely to the mercy of the man on top of him. Tony immediately moved one hand down, caressing Steve's thigh from the knee and all the way up, until he had one finger pressed against his hole. As he slowly pressed it in, he kept his eyes strictly on Steve's face, watching for even the slightest signs of pain. There was nothing save the slightest wince, and the billionaire carefully began pumping the digit in and out gently, making sure to keep his movements soft, avoiding any sudden intrusions. After a few minutes, he added a second finger, relieved when, instead of wincing in pain, Steve's brow lined with pleasure. Suddenly the soldier writhed and almost shouted beneath him, and Tony, repeating the motion he had just done, realised that he had found his prostate. Through stimulation of the small bundle of nerves, he managed to begin scissoring, and soon withdrew his fingers, much to Steve's resentment. Tony ignored the mewling complaint and spat in his hands, coating his own erection before positioning himself at the soldier's entrance. He looked Steve deep in the eyes.

"If at any point you're in pain, stop me." He said, before pressing in in one fluid motion. Steve gasped, mewled, moaned, growled, thrashed and clawed at his back until he was, at last, fully sheathed, and gave the soldier a moment to adjust.

"Please, Tony, please…" Steve groaned, his arms wrapping around Tony's shoulders to pull him close. The billionaire got the hint, and he slowly withdrew and pressed in again, earning him a delicious moan. Then he began thrusting, gently and slowly at first, both men gasping with each thrust, soon creating a rhythm. Steve hooked his right leg around Tony's hips and urged him deeper, without words asking him for more, more, more. Tony was only too happy to oblige, and gradually their pace sped up, the sound of skin slapping against skin becoming prevalent in the room, underlined by their moans and the sound of the occasional sloppy kiss.

Tony grasped Steve's gloriously broad, muscular shoulders, bracing himself to thrust harder. He was rewarded with Steve leaning his head against the floor and letting it the most obscene moan, followed by a strangled repetition of Tony's name in more or less completed versions.

"Tony, To-ny, T-Tony!" Steve repeated his name over and over, holding him so close it was almost painful, as Tony kept his fast and rough pace, forgetting all about being gentle, he ravished the man beneath him, with every inch of himself, and Steve relished it, feeling himself lose control so utterly and completely was more enthralling than anything he had previously experienced. He could feel each thrust, rougher than the previous one, spread a fire in his loins. Sweat glistened on both their bodies as they held onto each other as though they were trying to merge. Somewhere along the line, Steve lost track of where he stopped and Tony began, and he felt himself gasp for air, clawing at Tony's back.

Suddenly he felt pressure begin to build in his groin, and he knew that he wouldn't last much longer. "Tony, I'm going to – " He didn't manage to finish his sentence, clenching his teeth together as Tony wrapped a warm hand around his manhood.

"Come for me." The billionaire growled, beginning to jerk him off. And Steve came, so hard he thought he would faint, a blinding moment of pleasure burning, like diamonds spreading through his entire body. Tony followed almost only a split second after, spilling his hot seed within the man beneath him.

They lay together, a mess of entangled limbs, for several minutes, both catching their breaths. Steve was the first to speak.

"What happens now?" He asked, his eyes only barely open as he looked up at the man on top of him. Tony smiled, a quirky half-smile, and looked into his eyes. "Depends. On what you want. I wouldn't mind doing this more often, but I can't be monogamous. You know that."

At that, Steve smiled, though the smile didn't reach his eyes. "Yes, I know. I'm not good at sharing, but perhaps I'll give it a try." He mumbled. He was answered by a gentle kiss, Tony's lips pressing against his.

"I'd be glad of that, Cap. Really."
