“You ready?” Steve asked.
“Come on, Cap. When am I not ready to blast some bad guys?”
Steve heard a repulsor whirring to life somewhere over his shoulder. Trusting Tony to cover his back, Steve tightened his grip on the shield, took a deep breath, and kicked the door in.
Steve advanced into the room while shielding himself and Tony, the Iron Man suit bathing everything in familiar blue light, and—
Nothing. The room was nearly empty—abandoned. What little furniture remained made it clear that this used to be some kind of greenhouse and not the top secret weapons development facility SHIELD had told them it was.
“Well, that was anticlimactic,” Tony said, repulsors powering down. “J, scan for weapons, computers, secret panels—any tech that's not where it's supposed to be. Hell, throw in another thermal scan of the building, in case we missed some Hydra goons creeping around.”
“As you wish, Sir.”
“Tony, I… I don’t think there’s anything here,” Steve said. “Looks like bad intel.”
He took another glance around the room. There were plants lined up on desks along one of the walls, though most of them were wilted. A few office chairs and desks were scattered around, with broken computer screens and lab equipment laying on the floor. The most advanced technology remaining in the room seemed to be the high-powered lamps hanging above the plant section.
“Fuck,” Tony said, popping the faceplate of the armor, “This isn’t an evil Hydra lair. It’s a goddamn weed farm.”
“Tony,” Steve chastised.
“I mean it's clearly not cannabis—oh come on, don't give me that look, you went to art school,'' Tony said, and Steve didn't protest. “But, damn. All this trouble just for a couple fugly office plants?”
They probably should have been happy that there was nothing nefarious going on. But even Steve was feeling a little bummed: he'd been prepared for battle, and with the anticlimactic revelation it was like all his adrenaline had nowhere to go.
Though it was Tony who had been the most invested in this raid. Even if his name hadn’t come up in the mission brief, it only took the words “weapons development” for him to tense up during Hill's mission brief; and Steve couldn’t blame him. Bad guys worldwide had an uncanny ability of getting their hands on Stark tech and twisting it into something evil.
“Well, this was a waste of time,” Tony said, kicking at a beaker on the floor. “What an utterly stupid, inconsequential way to spend a Wednesday afternoon. Does Fury think I don't have anything better to do? Seriously, Pep's gonna have my head for canceling that seminar again.”
Steve ignored Tony's complaints and turned to leave. “We should report back.”
“I mean, we could take some samples of these,” Tony said, approaching the plants. “Get Bruce a souvenir so he doesn’t Hulk out while we bitch at Fury. You know, make this mission not a complete waste of Avengers time and resources?"
“SHIELD can do the grunt work,” Steve said. He frowned at the sight of Tony leaning over one of the plants; something felt off, but he couldn't pinpoint the cause. “Don't touch anything. Let’s just go.”
“Maybe Hydra's distilling the plants for some kinda super-evil-but-really-just-mildly-inconvenient poison elsewhere?” Tony kept going, not even listening. “Or, Jesus, even worse, what if some hare-brained aspiring scientist was inspired by good ol’ pal Killian's work—”
And that was when Tony, the most intelligent man Steve had met in his life, touched one of the mystery plants like an idiot.
Immediately, one of the flower buds burst open and spewed pollen right in Tony's face.
“Tony!”
Steve leapt across the room, tackling a coughing Tony away from the worst of it. But in the scuffle, they bumped into a table and even more flowers erupted into a thick cloud. Steve couldn't help inhaling the substance but he shoved his hand over Tony's mouth and dragged him away.
“Tony!" Steve called out. "God, Tony, are you okay?”
Steve’s throat felt dry and he blinked pollen from his irritated eyes. Yet it was nothing compared to Tony; he looked like he could barely stay upright much less breathe, even now that they were out of the thick of it and Steve had a hand on Tony's shoulders to steady him.
“I, uh, agh,” Tony coughed, tears in his eyes.
“Hold on,” Steve said. “I’ll get you out of here. Please, just hold on.”
“I think I figured it out,” Tony wheezed. “They were—they weren't using my tech. They were making bioweapons.”
Tony erupted into another coughing fit and Steve’s heart sank into his stomach.
Tony got exposed to a Hydra bioweapon. Now, he was hacking his lungs out—what if he choked, or went blind? Or died? God, why did he have to touch the damn flower!?
Tony coughed violently and then spit out a glob of pollen goo. He followed up with a raspy breath, his face red since the faceplate had offered no protection, because rather than stay safe Tony had lifted it like an idiot.
Focus, Steve chastised himself. He could berate Tony later; for now, he just needed him safe.
“Tony, we have to leave,” Steve said, forcing his voice to be level. “There might still be traces of the poison in the air, and we can’t have you get more exposed.”
“I’m—I’m fine. I think.” Tony rubbed his eyes, then blinked them open. “J, scan my vitals, would you?”
“Your pulse is elevated and there is breathlessness and low oxygen from the coughing, but your blood is clear of toxins, Sir.”
Steve breathed a sigh of relief. Maybe they were wrong; maybe these were just regular flowers, and the worst Tony was left with was a runny nose.
“Sir, I don't wish to alarm you," JARVIS added. "But your body temperature appears to be rising at an abnormal rate."
“Shit,” Tony said. “Now that you mention it, it’s getting a little stuffy in this armor.”
“Stuffy?” Steve said. “Tony, what’s going on?”
“I feel…” Tony grimaced and reached a gauntleted hand over his shoulder. “Antsy. Itchy. This isn't—wow, this really isn’t good. Reminds me of spring break in '86, when me and Rhodey had a really bad acid trip. Have I told you about that? What am I saying, of course I haven't—"
“Your heart rate is continuing to increase," JARVIS interrupted. "I fear an allergic reaction to the unidentified substance is taking place."
“Fuck," Tony commented. "Get me outta this armor.”
“What?" Steve balked. "Come on, we've gotta go—”
Steve choked on the rest of his sentence when the armor hissed open and Tony stepped out. He was wearing nothing but his form-fitting black undersuit: the one that left nothing to the imagination, though Steve had spent an embarrassing amount of time picturing just what lay underneath.
Steve shook his head. Focus, soldier.
“JARVIS, send the—” Steve started.
“God, it's hot in here,” Tony said. “It’s not just me, right? It's like a sauna in here.”
And that was the point that Tony apparently decided to start stripping: unzipping the second skin of the underarmor like from one of Steve’s numerous fantasies and shrugging off the top half, exposing broad shoulders and tanned skin.
“Captain Rogers?” JARVIS prompted.
“Right. Send the Avengers alarm,” Steve said.
“Very good.”
“Jesus, fuck, I’m sweating bullets here,” Tony said, and he was panting now, his chest naked and sweaty, and Steve—
Steve stared.
It was still weird to see Tony without the arc reactor. Steve knew it meant he was healthy, which was amazing, but there was something beautiful about the reactor: like a physical reminder of Tony's genius.
Not that Tony wasn't beautiful like this, too. The mess of scars and sparse hair on his chest took nothing away from how utterly sinful he looked: skin flushed and chest heaving, with dark nipples, firm muscle, and a slight softness around his waist.
"That's…that's better, gotta love that nice, cool, secret-Hydra-lair air," Tony babbled, his eyes hazy, like he was no longer even registering that Steve was there. "But—but, fuck, it's still so hot, everything, everything's burning and I—I just…"
Tony groaned, and his hips moved, making an aborted thrust into the air. Steve's gaze followed the movement, and, wow, the undersuit really left nothing to the imagination.
Tony was hard, straining against the tight fabric of his pants. Steve’s neck flushed hot and he quickly averted his eyes: Tony was in pain, and his body was just confused. This was no time for Steve to act on his repressed feelings.
Unfortunately, Tony just then seemed to notice his arousal, and immediately dropped a hand down over his pants.
“Oh, god,” Tony moaned. "That feels, that's so good, holy shit."
Tony closed his eyes and started palming himself shamelessly through the thin fabric. And Steve just watched, horrified and aroused, as his friend massaged his dick in front of Steve in the middle of a mission and holy hell, how was this real?
Just then, something clicked into place in Steve’s brain and he suddenly knew exactly what was happening.
“Tony—Tony, listen to me. I think you were drugged,” Steve said, managing to keep the rising panic out of his voice. “We need to get you out of here. JARVIS?”
“I have contacted the Avengers. Miss Romanoff gives an ETA of thirty-three minutes and requests that you stay in your position.”
“No, that’s not… we need to get him out! Come on, Tony!”
Rather than listen to Steve, Tony just kept masturbating, which decidedly was not helping.
“Tony, you have to listen to me!” Steve grabbed Tony by his shoulders.
The moment Steve's hands made contact with Tony's flushed skin, the reaction was instantaneous.
Tony jerked and looked at Steve like a man starved. And Steve had seen a lot of articles and interviews of Tony posing with a smirk and seductive eyes, but the infamous Tony Stark take me to bed look had never been directed at him before.
Yet right now, Tony's pupils were blown wide and his eyes were half-lidded, ogling Steve like he wanted to eat him.
"Steve," Tony breathed, like his name was a revelation. "Oh, god, Steve."
And, Jesus, Steve was strong, stronger than almost anyone else, but for Tony he'd always been weak. He could feel his resolve crumbling by the second under that heated gaze.
But...Tony was compromised. Tony didn't truly want this; he'd never looked at Steve like this when he was in his right mind, and he was only moaning Steve's name because of the drug.
"I, I don’t know what’s happening." Tony swallowed. "But I need to come—god, you don’t understand how much I need to. Please, please make me come, Steve, you have to, I—I can't."
Tony sounded pained and he clutched at Steve’s arm like a lifeline.
Steve's hands were trembling as he tried to hold himself back. Desire thrummed through his body. It had been so long since Steve had felt like this that he briefly wondered if he'd been affected by the pollen too.
But he knew that wasn't true. He felt aroused, yes, and high-strung from worry, but he was still in full control of his body. The serum made him immune to almost anything, probably having burned through the drug in seconds, and everything that Steve felt was simply because of Tony.
Tony made an impatient sound in his throat and squeezed Steve's biceps almost painfully. And that was when Steve made up his mind.
"Okay," Steve said. "Okay, let me take care of you."
He already knew he'd regret this later. But if the alternative was to keep Tony in pain, well, Steve would gladly bear the consequences of his actions.
"Thank you," Tony sighed, sounding genuinely relieved as he let go of the death grip on Steve's arms. "Thank you, thankyouthankyouthankyou."
Steve nodded stiffly and discarded his gloves before reaching for the hem of his uniform.
"You have no idea, fuck, my body, it's just—" Tony kept blabbering. "I've never felt like this, like hnnnnnngh."
The guttural sound Tony made once Steve's shirt came off was enough to make him flush all the way down to his now-exposed chest. Though Steve had aimed to get undressed efficiently and clinically, his stripping appeared to be having an inadvertent side effect—much like Tony's had on him.
Steve carelessly flung the shirt to the side and as soon as he did, there were hands grabbing at his shoulders and a very warm, still very shirtless Tony pressing up against his naked torso.
"Oh my god," Tony said. "Oh my fucking god, we're really doing this, I get to—I really get to touch you."
He sounded awed as he looked down between their shirtless chests, where Steve's bigger torso pressed up against Tony's lithe muscle. And then, Tony's hands were sliding down, and—
Tony squeezed Steve's pecs and Steve bit back a shamefully eager moan.
"Fuck," Tony groaned. He pressed his face against Steve’s neck, panting hot and open-mouthed against the skin. "Fuck, fuck, fuck, I'm, I'm so hard, and you're so—so hot, Jesus, how are you so hot?"
Tony was almost sobbing. His dick pressed against Steve's thigh, indeed hard enough that Steve actually worried Tony was going to come like this.
"Hey, Tony, hey, it’s okay," Steve said, trying to keep his tone soothing. "Let me—let's get you out of that suit, yeah? It looks pretty uncomfortable right now."
Tony's breath shuddered against Steve's neck before he managed a jerky nod. Steve carefully slipped his hands inside Tony's undersuit, still bunched up around his waist, and pulled it down.
"Good—that's good. Ease up a little?" Steve said.
Steve gently loosened Tony's grip on him so he could crouch and help Tony step out of his pants. Tony's cock bobbed hard and red in front of Steve's face and he flushed and quickly sat back on his heels to gauge Tony's situation.
Tony was already looking at him, trembling like a leaf. He was also naked, and gorgeous and, god, Steve wanted to do so many unspeakable things to him.
So Steve grabbed Tony by the back of his unsteady legs and leaned back, and then they were falling, until Steve's back hit the cold concrete floor and Tony was straddling him.
"What—what just happened.'' Tony blinked, like he hadn't even registered the movement.
"I, uh." Steve swallowed. "Wanted us to get more comfortable."
I've been fantasizing about you on top of me for the last two years, he strategically left out.
"What…oh,'' Tony said, seeming to notice the sight before him: a half-naked Captain America flushed and pliant under him. "Oh, god, Steve, you look…"
Tony didn't finish the sentence, opting instead to grind down against Steve with a filthy moan. Steve bit back any noise of his own, watching as Tony's cock slid hard and slick over his abs.
"You're so hot," Tony said. "Beautiful, sexy, gorgeous, I—mmh, you're so hot, it's not fair."
Tony was panting now, touching Steve all over: palming his abs and biceps, running callused fingers over Steve’s collarbone. Tony's speech was getting more incoherent by the minute, and Steve should probably be more worried about that, about Tony losing whatever wits he still had about him to the drug.
Instead, Steve's cock throbbed in his pants and his heart fluttered happily from Tony's mindless praise.
"You, uh. You too," Steve shot back lamely.
Rather than react to Steve's lackluster compliment, Tony chose to start massaging Steve’s pecs.
“Oh, wow, that—that's, yeah,” Tony said, gently squeezing the muscle and making Steve flush. “Jesus, you’re built like a god. Fuck, they should make…make statues, dedicated to your chest—America's chest.”
Well, that was… Steve wasn't sure how he felt about that idea, but at least Tony was talking more.
“Th….thanks?"
"Mmm," Tony commented, and then pushed his pecs together.
The simple action made Steve fidget in both embarrassment and arousal. Tony really liked his chest, huh?
“Oh,” Tony made a sound of awe, kneading Steve’s pecs and licking his lips. “Can we—can, can I—”
Tony was already shuffling up, his leaking cock bobbing over Steve's chest and making his intentions known loud and clear.
Oh. Tony really liked Steve's pecs.
"Yeah," Steve heard himself say. "Yes, Tony, god, anything."
He barely got the words out before Tony’s dick slid into the crevice of Steve's pecs, and, oh.
"Shit—fuck, this…" Tony panted. "Christ, Steve, your tits."
Steve swallowed a hot flash of shame and watched Tony set a rhythm thrusting between his pecs. It was filthy, watching the way Tony's cock disappeared between the mounds and then popped up at the top, the head red and leaking.
This was one thing that Steve had never done before, that he never saw the appeal of before now. He’d always thought it’d awkward or at the very least uncomfortable; but Tony was leaking like a faucet, quickly coating the space between his pecs in slick precum and making the slide wet and easy.
“Steve—fuck, Steve,” Tony said, reaching for one of Steve’s hands. “Hold—hold them together, like this, nice and tight, yeah?”
Steve’s ears burned with how red his face must have been. “Like this?”
He grabbed his pecs and squeezed them together around Tony’s cock, just like Tony had done.
And Tony went wild.
“Ah, ahh, oh god,” Tony moaned, sliding his cock between Steve’s pecs with renewed vigor. “Just, just like that, god, that’s a amazing—so, so tight, so good, oh, oh fuck.”
Steve never thought anyone would enjoy this so much. He didn't know he would enjoy this so much, but as he watched Tony’s face go slack with pleasure, felt his slick cock fuck desperately between his pecs, Steve’s neglected erection throbbed in his pants behind Tony’s undulating body.
It was humiliating, in a way, presenting himself for Tony this way and having Tony shamelessly use him for his own pleasure; but it was a good kind of shame, the kind that made Steve shiver and flush all over.
And then Tony, hands now free to do as he pleased, pinched Steve's nipples and Steve was toast.
“Oh, god,” Tony moaned. “Steve, Steve, your tits—your tits are fucking fantastic. I've always wanted to, to do this to you. You're so sensitive—feels good when I do this, doesn't it?”
Steve moaned and twitched under Tony's hands. Yes, his nipples were sensitive, embarrassingly so, and it had always been a point of insecurity. But Tony didn't seem to mind: his entire being radiated lust, and he was rock hard between Steve's pecs, looking down at Steve like Steve was his entire world—
Tony twisted his nipples hard and that was it. Steve came, a startled yell punching out of him as his hips lifted off the floor and he shot untouched into his combat pants.
Through the blinding pleasure, Steve tried his best to keep his pecs pressed together for Tony, to make it good for him. Dazed from his orgasm, he still kept looking at Tony, at his slick cock and wild eyes.
“Holy shit, you, you came? You came just from your tits, oh, sweetheart, you're so good, so sexy, this is so much better than I ever imagined, I—fuck, Steve—”
Tony came with a loud groan, painting Steve’s chest in messy spurts and landing on his neck and his chin. Steve moaned with him through it even as the finality of the situation started to set in.
This was it. Now it was over, and they only had to wait for the others—
“Fuck,” Tony said. "It's not working."
Steve looked down only to see Tony still hard. Which wasn't unusual for Steve's serum-enhanced body: he could usually go a good three or four times in a row, but…
Tony was only human. Tony was a normal man, at a mature age, and his cock definitely shouldn't stay rock solid after just coming his brains out.
“Why,'' Tony nearly sobbed. “Fuck, I'm so hard it hurts.”
Steve watched Tony's face twist in pain, watched him writhe on top of Steve in clear discomfort, and had a silent battle with himself.
Steve knew he bore full responsibility for the situation. Tony was practically incapacitated, drugged out of his mind, while Steve remained immune and fully conscious of his actions.
It was bad enough that Steve had allowed it to go this far. He should have suggested that Tony settle down and wait for backup to arrive or, worst case scenario, Steve would forcibly carry him out of this place.
But at the same time, Steve wanted. He'd wanted Tony for so very long and now that he had him, however briefly, he didn't know if he was strong enough to resist. Because watching Tony suffer was worse than the pain of any battle wound or asthma attack Steve had ever had to endure. He might not be what Tony wanted, but at this moment, maybe he was what Tony needed.
It was a flimsy excuse, but it made Steve feel a little better when he gripped Tony's thighs and said “fuck me.”
“I did,” Tony whined. “I did, and it was amazing, but I'm still, I need more.”
“No, Tony. Fuck. Me,” Steve said.
Because of the drug, Tony's genius brain was slower than usual to catch up. But when he did, Tony's eyes went wide and he let out a quiet gasp.
“You—you'd let me?" Tony asked breathlessly. "Shit, Steve, are we—you mean you’d really let me…?”
Deciding that actions might get the point across better than words, Steve wordlessly lifted Tony off his lap and shucked off his uniform pants along with his underwear. The reminder of the stickiness in his briefs sent a rush of shame through him, but he gave Tony no such indication.
Without fanfare, Steve turned around on all fours. The concrete floor was still uncomfortable, but better him bear it than Tony.
“Oh god, oh my god,” Tony moaned behind him.
Callused hands palmed at Steve's ass, spreading his buttocks. Steve didn't know if it was him or Tony that was shaking.
“God, you look so good. So tight."
Tony circled his rim with a finger and Steve jolted, grunting in surprise.
“I cant believe you’d—fuck. Fuck, I’ve wanted this so long, and I wanna make it good for you, but I—I don't have anything, and…”
Yeah, well. Steve knew neither of them had anything to make this easier, but he also knew his body well enough to be sure he'd manage. Besides, Tony was still wet, leaking constantly—it had to be a side effect of the drug—and though it might chafe a little in the beginning, Steve could take it.
He wanted to take it, for Tony.
“I don't need anything,” Steve said. “Just go for it.”
“Oh, fuck,” Tony moaned, and then he shifted behind Steve, and—
Steve let out a startled yell when he felt a tongue prodding at his hole.
Tony wasted no time, licking at his ass like a man starved, with a loud and filthy moan like this was pleasure for him and not Steve.
Steve bowed his head and tried to suppress his whimpers; he was sensitive all over, and this was no exception. Tony kissed and lapped at his ass, breath ragged and goatee scratching against Steve's perineum, and it felt incredible.
“Oh, oh god,” Tony panted. “Your ass, Steve, I can't—”
Tony made a choked whine and roughly grabbed Steve’s buttcheeks to spread them wide before diving in. He wiggled his tongue into Steve's body, stretching his hole deliciously, and Steve couldn't, how was he supposed to hold on when that was Tony’s tongue inside him—
With a scream, Steve came again, splattering onto the concrete and clenching around Tony's tongue.
Tony worked him through it, licking at him inside and not allowing Steve's clenching body to slow him down. Steve realized that Tony was moaning, a constant sound and vibrations against Steve's clenching rim.
Tony pulled off and was immediately back to running his mouth. “Holy shit, that was hot, so hot, you’re so good, fuck, Steve, I can't… I'm so hard, I, I think I'm actually gonna die if I don’t get to fuck you, please, please let me fuck you.”
Steve glanced over his shoulder. Tony was fisting his own cock; the tip was flushed dark and almost purple, and Tony looked like he was in agony, grimacing while he roughly tugged on his length.
“Put it in,” Steve said. His voice was gruff, like he was giving an order in the field, telling Tony to put on the suit.
And Tony whimpered “thank you, thank you so much” and scrambled to obey, lining himself up with Steve's hole and pushing.
Steve grunted at the pressure against the tense muscle. It was a tight fit, and not an easy ride even with Tony's leaking cock and the spit still clinging to Steve's rim.
But any discomfort Steve might have felt was drowned out by the filthy, unabashed moan Tony let out as soon as the head popped in. His hips immediately stuttered forward, nudging his cock further inside and forcing Steve to take more, feeding his cock into Steve's clenching body.
“Oh fuck, oh, that’s it, you can do it, baby, god, you're taking me so well,” Tony murmured.
And Steve bit his lips to muffle a whine, because it was good—it was perfect. He'd always liked it rough, and like this he could feel everything. But he had to keep his voice down: Tony could never know how much Steve loved being taken like this, how his leader had fantasized about being on his knees and used by Tony.
Tony eventually bottomed out and then he stayed in place, trembling all over. Steve was already back to full hardness, because how could he not be, with Tony around him, inside him, surrounding him everywhere.
“Steve… Steve,” Tony groaned. “You feel amazing, so tight, so fucking tight, and I can't, I want to make it good for you but I can't.”
“Do it,” Steve rasped. “Fuck me. I can take it.”
And that was all it took. Tony pulled out and pushed back in, making Steve gasp and stretching his hole further, forcing his body to adapt. Tony moaned and then did it again, harder this time, setting a punishing pace fucking into Steve's body, the obscene noises of their moans and skin slapping against skin filling the room.
It was better than Steve had ever dreamed. He was so turned on it felt like he was affected by the drug too; shame burned hot on his face but he didn't stop, only braced his arms against the floor and rocked back onto Tony's cock.
Steve came again at some point: not really registering it, other than the pained whimpers Tony made as Steve clenched around his cock. It prompted Tony to grab his hips brutally and pump faster, harder, coaxing Steve's overstimulated body back to arousal.
“You're so good, so amazing, I love you,” Tony said between thrusts. "God, Steve, I love you, you’re perfect.”
Steve flushed and ignored Tony's blabbering: he had to be really out of it to be speaking like that. Though that fact didn't register with Steve’s cock, which was already chubbing back up, half-hard and twitching with the sweet words spilling out of Tony’s mouth.
“God, Tony,” Steve moaned. “Don’t stop.”
“Never, never gonna stop, gonna keep fucking you until I die, you—fuck, Steve, you feel so good,” Tony said.
His cock slammed in and out of Steve’s body, making the concrete crack under Steve’s hands as he dug his fingers into the floor.
And then Tony bowed over him, chest to back. The new angle of thrusts nailed Steve’s prostate and he cried out, loud enough that he’d be embarrassed if it didn’t feel so fucking good.
“Oh, oh, darling,” Tony panted into Steve’s sweaty neck. One of his hands left Steve’s hip, circling around to grab at his cock and making Steve jolt. “One more,” Tony said, tugging on Steve's dick with uncoordinated movements. “Please, sugar, one more. Come on my cock, you clench up so nice, so good for me.”
And Steve was helpless: the words, the assault on his prostate, the hand on his cock, they all blended together into blinding pleasure until he came with another scream.
This time, Tony followed, grabbing Steve’s hips and fucking him hard and deep through the release. Tony spilled into his clenching body, a ragged moan tearing out of his throat while his nails dug into Steve's hips hard enough to break skin.
After it was over, once Tony's thrusts stilled and he slumped over Steve's back, Tony sobbed out one last “thank you” and promptly passed out.
And Steve lied there: sweaty and covered in his own come, with Tony's finally softening dick still inside him and blood pricking at the scratch marks on his hips.
That was when the door slammed open with a crack of thunder and a sob broke free from Steve as he realized what he had just done.
—
The team found them like that: naked and collapsed together in the abandoned room, the evidence of Steve's depravity all over them.
Clint and Thor stopped in the doorway, uncertain how to proceed. Meanwhile, Natasha approached without a word and helped lift Tony's unconscious body away from Steve.
Steve didn't trust himself to speak, so JARVIS took it upon himself to inform the others of Tony's exposure to the unknown substance while Steve shamefully collected the discarded parts of his uniform.
Clint pulled out a mask and volunteered to take a sample of the plant—Steve didn't question why he carried a gas mask in his quiver—while Natasha wrapped Tony in Thor's cape and the god easily carried him out.
Natasha used her override code to get JARVIS to pack up the armor. Because, god, they all had overrides to Tony's tech. Tony had given them codes, because he trusted them with his armor and his life, and Steve had—
"Come on," Natasha said as soon as Steve was dressed. "I can't carry the suit."
Steve nodded stiffly and picked up both his shield and the suitcase-sized cube that the Iron Man armor had morphed into.
–
A strong aphrodisiac.
That was what Bruce, after analyzing the sample, had deduced it to be.
"It's unlike anything I've ever seen," Bruce said. "Like an overdose of Viagra in airborne form. With Tony's medical record, he was lucky to make it out without damage to his heart."
His…his heart? God, Steve could have given Tony a heart attack, with—with what he did.
"So…" Clint broke the heavy silence that had settled over them. "Sex pollen?"
Bruce sighed and pinched the bridge of his nose while Natasha smacked Clint upside the head.
And apart from a few sympathetic looks aimed at Steve, nobody brought up what happened in the Hydra base.
—
Steve couldn't bring himself to face Tony.
Upon waking up, Tony had been discharged from medical after only a few hours. The toxin had already cleared itself from his system and his heart—thank god—was unharmed despite the potent drug. Steve's cuts and scrapes had healed before they'd even made it back to the tower, and despite both him and Tony being okay physically…
Steve would never be able to forgive himself.
Tony had asked for consent. Even drugged out of his mind, he had asked Steve before touching him, before getting himself off on Steve's body, and before taking him.
Meanwhile, Steve had just taken advantage.
He didn't know how much Tony remembered. It didn't change the severity of Steve's action, but for Tony's sake, Steve hoped he didn't remember Steve forcing himself on him. Tony had enough bad memories without Steve added to the mix: he'd suffered too much for one lifetime, he'd trusted Steve, and Steve—
And Steve had betrayed him.
Had betrayed him like Stane and Hammer and the rest of those weasels, shown his true colors as soon as Tony's guard was down.
And so Steve hid like a coward: spending all of his free time in the gym or holed up in his room.
—
It was a week before Steve forced himself into action.
He'd heard from the others that Tony had spent much of the past week at the tower, which was unusual. Normally, he'd travel around to different business meetings around the world or at least be busy with countless obligations in New York.
Any other week, it would have made Steve's day to know that Tony was here in their shared home, but now it felt oppressive. Like Tony was using his presence to remind Steve that he gave him a home and he could just as easily take it away.
That only cemented the fact that Steve didn't deserve to live in the tower. He didn't deserve to be near Tony, and how the team left him unsupervised was beyond him.
Yet, no matter how guilty Steve felt, he couldn't stop thinking about that day.
The serum had always made his libido difficult to manage and Steve couldn't go many days without bringing himself relief. But now it was somehow even worse; his body demanded attention several times a day, like his dick hadn't gotten the memo that not only was what happened between Steve and Tony a one-time-thing, it was also morally despicable.
It wasn't like the shame was new to Steve: on the contrary, he'd known for years that it was wrong to think about Tony when he masturbated, because Tony was his friend and decidedly did not see Steve that way. But now? Steve had a mental movie reel—curse his eidetic memory!—of himself having sex with Tony to resort to.
And so every day, Steve pleasured himself to the images and memories of himself sexually assaulting his teammate, and it was disgusting.
But he also came faster and harder than he’d ever done before this. He only had to think about the feeling of Tony inside him and the memory of Tony’s goatee scraping against his neck, about Tony pleading one more, Steve, one more, you tighten up so nice around me when you come.
On the seventh such night in a row, Steve looked down at the sticky mess in his hand and knew that this needed to stop.
Steve grit his teeth and set for the workshop.
—
Despite the late hour Steve found Tony in his workshop, tinkering away.
It was a familiar sight that instantly made Steve feel more at ease. Steve didn't often come down here, but even he noticed the slight disarray in the workshop: some machines had been moved from their usual spots and cardboard boxes had inexplicably appeared around the place.
But Tony's head was bobbing with the music and he appeared intently focused on his work, which was a good sign.
…Unless Tony hadn't eaten or slept again and was only doing this as a distraction from the pain and betrayal—
Steve forced himself to knock on the glass wall between them before he chickened out.
Tony looked up and as soon as their eyes met, the fake smile Steve recognized from press conferences and SHIELD debriefs plastered itself onto Tony’s face.
“Steve!” Tony's voice carried through the speakers above the door. “To what do I owe the pleasure of Captain America in my humble workshop?”
Steve resolutely ignored the flash of something the word pleasure caused. “We need to talk.”
Tony’s smile appeared even more forced. “Well, come on in then.”
“I think it's best to keep a wall between us,” Steve said, shame hot and unpleasant in his gut. “I don't trust myself around you.”
Tony's face fell, the fake pleasantries replaced by something cold and unreadable.
“J, close off the floor.” And then Tony seemed to catch himself. “No, I mean—only let Steve out. Don't let anyone else in.”
God, Tony really wanted him gone that badly. Steve would try to make this quick, but he needed to apologize properly.
“I'm sorry,” Steve said, his voice breaking. “I know that probably means nothing, but I am so, so sorry. There's no excuse for what I did to you, and I know I need to leave the team. You have every right to press charges—”
“Woah, woah, what, hold up.” Tony raised his hands. “Is… is this some new branch of reverse psychology? Advanced victim blaming?”
Steve frowned. “No. I mean it.”
“Then why the fuck is Captain America standing here and apologizing for me raping him?”
Steve flinched like he’d just been burned. He didn't want to use that word, had shied away from it like a coward, yet that's exactly what had happened.
Except… Tony had it the wrong way around.
“Tony, I… I think you're confused.” Steve said. “It was the—the other way around. I wasn't affected by the drug.”
“Don't lie to me, Steven,” Tony snarled. “Do you think it's gonna make me feel better if you claim you were sober enough to consent?”
Steve floundered for an explanation. Luckily, he had unexpected backup.
“If I may,” JARVIS interrupted. “Sir, like I've stated previously, Captain Rogers was not compromised by the substance.”
“No, no, that's wrong,” Tony waved off. “Calibration error. We were both hit, and it wore off before we got to medical, so it didn't show up in Bruce's tests.”
“But I wasn't,” Steve said. “Tony, you were the compromised one. I retained full bodily autonomy the entire time. The serum makes me immune—you know that.”
“Yeah, right. So you went face down, ass up just for the hell of it?” Tony snarked.
Steve's face flushed hot but he didn't protest. What was he supposed to say? Yes, Tony, and I very much enjoyed getting railed by you while you were drugged?
“Uh,” Tony said into the silence. “Cap. This is the part where you yell at me and say you're not gay, and that I'm a terrible human being who coerced you and who should be locked away, just so I can never hurt anyone again. God knows I've earned it, with my track record.”
The last part was muttered, like it wasn't meant for Steve to hear.
“Tony.” Steve steeled himself. “I think the drug messed with your memories.”
“Oh, no, I remember everything in very vivid detail,” Tony said ruefully.
“Well, I…” Steve cleared his throat and tried not to think about what he had done with his own memories. “What happened a week ago is that you got exposed to a drug that made you aroused. I was immune, so when we… When you propositioned me and we slept together, that was me taking advantage of your state. You couldn't consent.”
Confusion flashed on Tony's face as his brain worked to piece together the information.
“You're not lying,” Tony said. “You've always been shit at lying, and now…it doesn't look like you are. Are you lying?”
“I'm not,” Steve said. “I wouldn't lie about this.”
“Then why?” Tony frowned. “Your teammate gets hit with a sex drug and starts rubbing up on your, and you…let them fuck you? Do you think that's your Captainly duty or something? That if it’s on your watch, you need to help your team like that, because fuck, Steve, somebody needs to teach you about consent if you'd drop your pants for me, or any of us, and—for fuck's sake, it could have been the Hulk!”
“No!” Steve said. “I wouldn't—I didn't, not—not because of duty. I knew exactly what I was doing and who I was doing it with. I was fully in my right mind. You weren't. Which means this is my responsibility.”
Tony tilted his head comically.
“You…you let me fuck you… because you wanted me to fuck you?”
Steve sighed. “Yes.”
“What the fuck,” Tony said, again as to himself. “What the fuck, Steve, you—you even let me fuck your tits!”
Steve flushed but stayed strong. “Yes.”
“And—and when you came four times, that…that wasn't the drug?”
“That was because I liked it.” Steve's face was beet red. “The…the four times, that's… the serum. It's normal.”
Tony stared. And then stared some more.
“You… liked it?” Tony said. “Jesus, Steve, I was terrible! I just chased my own pleasure like some kind of animal. And, and we did it dry, that can’t have been good for you, oh, god, I'm so sorry—”
“You're wrong.” Steve blurted. “I—my body can take a lot. If it wasn't good for me, if you'd hurt me, I could have easily stopped you.”
“But you didn’t,” Tony said, then frowned. “Why didn’t you, again?”
“I told you; I liked it.” Steve cleared his throat. “I liked it so much that…that, after, I've touched myself to the memory of you on me. Around me. In me.”
Steve kind of felt like curling up and dying after that confession. But, finally, Tony didn't seem upset anymore. If anything, he was starting to look more curious.
“You... What?”
“Daily. Several times a day. It's… a problem,” Steve forced the words out. “I came here because...because it's wrong. I thought it would stop if you yelled at me, if you told me just how disgusting I am for betraying your trust.”
“No, no, god, Steve, no,” Tony said. “That's…extremely flattering, actually. I, uh, I mean. Same. I tried not to think about you when I… yeah. But how was I supposed to resist? You're literally my wet dream come true. I'm a bad, bad man and this is no exception.”
“You're not a bad man, Tony,” Steve said. “I'm glad you—I'm glad you have fond memories of what happened. Maybe it helps to deal with it.”
“So…you liked it.” The ghost of a smile flashed over Tony’s lips. “Even the…well, the parts where I had as much finesse as a fourteen year old Tony who jerked off at his Cap poster.”
“I liked it,” Steve said, resolutely ignoring the fluttering of hope in his chest. “All of it. The only thing I would have changed is… well, that you'd have been there, uh, mentally. Other than that I…I, uh, like it rough.”
“You like it rough,” Tony repeated again. “So I…didn't brutally rape a virgin Captain America?”
“None—neither of those.” Steve cleared his throat. “Not the…you didn't force yourself on me, and, uh. Not a virgin. Not for the past seventy years—the, uh, the army's a good place for…experimenting, especially with a new serum-enhanced body.” Steve blushed. “So, I, ah, I've definitely been with fellas before. And when you said Captain America isn't gay…it's not, well, exactly true.”
Tony's mouth was comically slack until he shook himself out of it. “Okay. Okay. I'm going to open the door,” Tony said. “You can leave anytime, but I physically need to open the door, right now, because I can't just watch you stand there and be all—all bashful and reasonable. So, door, okay?”
Steve nodded and JARVIS took the initiative to slide the door open.
Tony took a hesitant step forward, and that was the cue Steve needed to stride into the workshop.
“You…” Tony stared at him, only a few feet between them. “You're really not mad at me.”
“No, Tony, never,” Steve said, then frowned. “You sure you're okay? This must be disorienting for you. I'm so sorry for what happened—”
“Nope, nuh-uh, no señor,” Tony said. “You don’t get to be sorry. You liked having sex with me? Well then imagine how I felt, getting to live my favorite sex fantasy of thirty years and have the whole thing ramped up to eleven because of sex pollen.”
Steve flushed. “Oh.”
There was a beat of silence, and then Tony groaned dramatically.
“Oh, god." Tony rubbed his forehead. “How am I supposed to live with the fact that I know just how far down that blush goes? Wait, no, sorry, that's inappropriate—fuck, I cant believe that you wanted to have sex with me. What a lapse in judgment, huh?”
Tony was grinning at him, an attempt at deflecting that made Steve frown.
“I've wanted you for a long time,” Steve said. He didn't realize the gravity of the statement until Tony's eyes went wide. “I—I mean. I thought that was obvious, from the way… from how I acted.”
“I'm dreaming,” Tony said. “Or I'm dead and went to heaven. The drug was poison and I died instantly. What else could this be? I’m just surprised I went to heaven, because, really, that’s the only explanation for why someone like you would ever want me.”
“Is it really that hard to believe?” Steve said. “You're…you're important to me. And I don’t like hearing you put yourself down.”
“You're still not lying,” Tony said, amazed. Then he cleared his throat. “Well, I'm glad we got this whole mess cleaned up. Thanks for being so understanding, that… it means a lot, Cap.”
And, just like that, Tony promptly turned back to his work.
“Oh,” Steve said, disappointed. “That's…that's it?”
“Well, yeah?” Tony glanced at him. “We just established we had an enjoyable tumble in the sheets—concrete?—together, and neither of us has to feel guilty about it. And, that? About two hundred and fifty percent better than I ever anticipated this conversation going. So we're good, right?”
Steve stamped down harder on the hope inside him.
“Right," Steve said.
Tony tilted his head, his expression unreadable. “Unless...?”
Steve swallowed. I'm in love with you, he should say.
“What are the boxes for?” he asked like a coward.
“Oh, those.” Tony chewed on his lip and looked at a half-open box. “Well, I was kind of in the middle of moving out of the tower.”
Steve’s heart felt like it was sinking through the floor below him. “Because of me?”
“Yes—well, no, technically because of myself and how I thought I’d scarred you for life,” Tony said. “I mean, if I really had forced myself on you, I wouldn’t have any right to stay here. To be around you.”
“But…Tony, this is your home.”
“No,” Tony said, his expression firm. “It's all of our home, and if I fucked up, I should be the one to leave.”
Steve was surprised at the determination behind Tony's words. At the same time, he was just glad that he got here in time to stop his plans of leaving.
“But, well, obviously I no longer need to,” Tony said. “Which is amazing, and—and is gonna have a very high risk of making me emotional if I allow myself to think about it, getting to stay here and not having you hate me.” Tony swallowed.
The thought of Tony fearing Steve hating him was somehow even worse than the week Steve had spent thinking Tony never wanted to see him again.
“God, Tony. Never,” Steve said.
“Well, anyway.” Tony cleared his throat. “I was gonna leave you with some of this stuff in case Bruce or the spy kids needed to tinker with something. I was planning to just finish up this project and then be on my merry way, but now I have some bots to unpack and a spare penthouse apartment to gift to Pepper. So, uh. Thanks. For not kicking me out.”
Steve's eyes were misting. Tony would really have picked up his whole life and left his home and his team, his family, because he thought he'd hurt Steve.
“What was the project?” Steve asked, not caring if his voice was a little unsteady.
“Oh, these?” Tony turned around to his workstation. “Just some new tech for the team.”
He grabbed what looked to be some kind of visor. “This is a retractable filter mask,” Tony said. “It slots into a new earpiece and automatically deploys when it detects certain substances.”
Steve nodded, feeling just as awed as he always did when Tony showed off his inventions.
“The other one's an arm strap,” Tony said, pointing at what looked like a simple collar. “It monitors toxins and foreign substances in the blood and sends an alert to JARVIS and the team if someone’s in danger. I'm gonna integrate it with Bruce's lab to automatically synthesize any known antidotes. And it’s recalibrated to account for organic matter and supersoldier serum, but, y’know, maybe don't wear it during one of Thor's mead-drinking contests or you could trigger a false alarm. Because god knows—or maybe they don't, ha—what's in that stuff.”
Steve's heart throbbed with emotion. Tony always looked out for the team, spending days and nights making sure they were safe on the field. How did Tony ever think that the Avengers would kick him out? They needed him; Steve needed him.
But he couldn't say that, could he?
“These are great, Tony,” Steve said, trying to keep the adoration from bleeding into his expression.
“I made them for you,” Tony said, and it felt like Steve had been punched in the gut. “If I was gonna get kicked out, at least I wanted you to be safe. So that nobody could do anything like that to you again, which...yeah, seems kinda like a moot point now.”
The confession had Steve reeling. He could no longer keep the affection from bubbling up and threatening to spill over.
Tony thought Steve would want him gone, would hate him, and as his last act as an Avenger was to create gadgets that would protect Steve in the future?
“But, hey, they should still prove useful,” Tony said. “And I figured I'd throw in ones for the whole team, too. Since bioweapons might be in our future and—”
“I love you,” Steve blurted out.
“—and I'd really hate for Hydra to get a jump on us again, and.” Tony suddenly paused. “Wait—hold up. What did you just say? Because—because I admit I'm not really known for listening to people, but I could’ve sworn you just said…”
Tony trailed off and Steve swallowed and steeled himself.
“I’m in love with you,” Steve repeated.
Tony blinked. “You really liked that sex, huh? Wow, maybe I should get drugged more often, if it’s enough to actually make people fall in love with me out of the blue. Cupid’s bow, magic dick, what's the difference, right?”
Rejection. Though Steve knew it was coming, it still hurt. And maybe he was digging his own grave, but he needed Tony to know the full truth.
“—I mean, I always wanted a superpower, but come on, how do you brand magic dick in a way that's not a PR nightmare—”
“It wasn't just the sex,” Steve said.
Tony's sentence screeched to a halt.
“I…I've felt this way for a long time,” Steve said. “Way before last week. It wasn’t the sex—even if that, uh, was very nice.”
Steve's face felt too hot. God, he was a mess.
“When I say I want you, I don't mean just your body,” Steve said. “I want—god, Tony, I want all of you. And that's why it was so hard to resist, when you looked at me like you wanted me too.”
“I did,” Tony blurted.
“You…did?” Steve asked.
“What do you mean, you did? Of course I did—do. I do want you.” Then he laughed, somewhat hysterical. “Listen to me, I do, I do, you'd think we were getting married or something.”
Now it was Steve’s turn to be stunned into silence.
“God, this is surreal,” Tony said. “I've literally had my tongue in your ass and now I can barely even say ‘hey, by the way, I like you.’"
Steve flushed but decided not to comment.
“Well, since we're having this heart to heart.” Tony sighed. “And since I don't have control over the shit that leaves my mouth on a good day, much less a drugged-into-extreme-horniness-day, I'm ninety-nine point three percent sure that a week ago I, uh, told you exactly how I feel about you—how I've felt about you for a long time. In very vivid, excruciating detail.”
“I…” Steve swallowed.
You're so good, so amazing, I love you—god, Steve, I love you, his supermemory helpfully provided.
“You wouldn't be the first man to say things he regrets during coitus,” Steve said.
"Well, I'm not claiming I haven't been beating myself up over it for the past week—even if it wasn't my main concern." Tony looked away. "But, I, uh, the things I remember saying? All true. And—and not just about your tight ass—"
Steve made a strangled noise.
"Right, fuck, shit. Inappropriate. Shutting up now," Tony said.
"I, uh." Steve cleared his throat again. "So if you… can… would we… uh."
"Okay, I know I said I'm shutting up," Tony said. "But it would actually really help if at least one of us could string together a coherent sentence. So, I humbly ask that you say what's on your mind, before I end up talking more about my tongue in your ass."
This time, Steve only huffed out a surprised chuckle.
"I was just wondering if I could kiss you," Steve said.
Tony immediately perked up, a grin pulling at his lips. "Oh—oh Cap, Steve, honey pumpkin."
He strode up to Steve, oil-stained hands coming up to rest on Steve's shoulders.
"I completely, one hundred percent understand why you'd feel the need to ask, after—well, after," Tony said. "But let me assure you, that effective immediately, you have my full permission to kiss me whenever you want. Well, maybe not when we're fighting bad guys, because that's gonna leave you open for an attack and we know how I feel about you getting hurt. But any other time, I swear, even in the middle of a board meeting—"
Steve smiled as Tony kept going. But since the genius showed no sign of stopping his rambling, Steve decided to use his newfound kissing rights straight away.
"—And, honestly, fuck anyone who tries to tell me it's inappropriate to make out with you in public. Because, hello, have they hmmgh."
Tony made a surprised noise in the back of his throat when his sentence was interrupted by Steve's mouth on his. But he quickly adapted, wrapping his hands around Steve's neck and returning the kiss with a pleased hum.
And Steve realized that as nice as the sex had been, he'd never actually got to kiss Tony during it. Steve had thought he wasn't allowed, like that would be crossing a line. It would no longer have been just physical, but rather something intimate. Something deliberate.
But now he got to kiss Tony, because this was no longer about just the sex—it had probably never been just about the sex, for either of them.
Now, there were Tony's soft lips moving against Steve's own, Tony's goatee scratching against Steve's clean shaven chin and a devious tongue barely dipping out to tease at Steve's top lip. And Steve could do nothing but let out a deep, satisfied moan and slant his mouth, melting into the kiss.
"We're doing this?" Tony asked when they pulled apart for air. "The—the kiss kiss hold hands go on dates and yell at Tony for buying strawberries again? Or, well, you're probably not allergic to anything, which is a definite plus, because I can't accidentally kill you with gifts. Unless a giant plushie falls on you, but you're probably strong enough to handle that."
Steve took a moment to reorient himself. His mind was still reeling from the confession and the kiss, but it would figure that Tony's had already moved a lightyear ahead.
"I don't know about the berries and plushies," Steve said, "but I do know I wanna ration you."
"Ration?" Tony was grinning. "Oh my god, that's incredible. Haven't heard that one in—well, ever, and honestly I'm not fluent enough in forties slang to be completely sure it means what I think it does—"
Steve kissed him again, because it both got Tony to stop talking and because kissing Tony was thoroughly enjoyable. And Tony did say he had permission.
"It means I want you to be mine," Steve murmured.
"Well, then, I am very on board with that plan." Tony smirked. "And it just so happens that I'd also be very on board with taking a break from work and moving this to the couch. Maybe put the shop in blackout and be a completely mature adult and make out with my new boyfriend for half an hour."
Steve chuckled and steered them towards the couch. "That's a very specific thing to be on board with."
"What can I say?" Tony winked and pulled Steve down to sit beside him. "I'm a futurist."
Steve smiled and leaned in for another taste of Tony's lips. Unfortunately, he barely had time for a quick peck before Tony was talking again.
"For the record, I'm also on board with absolutely anything that happens on this couch or maybe even against one of these lovely workbenches," Tony said. "I mean, after the tongue in ass action there's really not much to be modest about—"
"You really do love bringing that up."
"Absolute highlight of my life, will never shut up about it." Tony grinned. "But, anyway, I just needed to say, when—when, if, hopefully?—we end up sleeping together again… I'm usually a much, much better lay than what you saw the other week."
Steve laughed. "I thought you did just fine."
"Oh, just you wait." Tony was smirking now, a mischievous look in his eyes. "Wait until you see me with actual brain capacity that's not just 'ooga booga put cock in Steve.' I—well, I'm not gonna be able to repeat the party trick of multiple orgasms, but, I'm gonna make sure you get yours. Not to brag, but I haven't had any complaints in that department before."
Steve smiled and placed a comforting hand on Tony's thigh. "I know you'll be amazing. No strange flowers or questionable Hydra experiments needed."
"Speaking of…" Tony said. "Do you think Bruce still has some of that pollen? Asking for a friend."
"Tony."
"Okay, fine," Tony sighed, his head slumping down on Steve's shoulder. "No performance enhancing sex drugs."
Steve nuzzled closer to murmur in Tony's ear. "I don't need an aphrodisiac to make you come harder than you have in your entire life."
It caused Steve no small amount of pleasure to see Tony flounder and honest to god blush. And then, Steve was taking advantage of Tony's slack mouth to finally kiss him again.
And once Tony collected his wits, callused hands pushing Steve down to lay on the couch while Tony climbed on top of him, Steve only smiled against warm lips and revelled in the pleasant feeling of déjà vu.
Because Steve already knew that this time—and all the other ones that followed—would be even better than the last.
