The coffee machine gurgled as you stood at the mansion's vast kitchen counter, eyes glued on the wall-mounted TV screen. The newscaster was debriefing viewers on Iron Man's latest victory, how he had saved dozens from an armed-robbery hostage situation at one of the largest banks in the city. Everyone had gotten out safely, the bad guys were all in cuffs, and the news outlets had a breaking story to keep them busy for the day. Adoring fans took turns gushing into the journalist's mic about the famed superhero, making the side of your lips quirk up a bit in pride.

The moment was then ruined by a high-pitched whooshing sound overhead, signaling Tony's return. You winced at the chaotic bang of him crashing through walls and falling down into the lab, followed by muffled yelling and cursing.

"Every single time," you muttered with a shake of your head, not even wanting to know what expensive piece of equipment he had probably just destroyed with his graceful landing.

Grabbing two mugs out of the cupboard, you took your time filling them with the freshly brewed coffee and adding the appropriate amounts of cream and sugar to each one. Taking a deep breath, you picked up the cups and reluctantly headed downstairs to assess the damage.

Sure enough, the debris was still settling, clouds of freshly-startled dust particles floating through the air as you descended the steps. Tony was currently out of view, but you could hear the heavy metal footsteps of the suit as he strode around while barking orders to FRIDAY.

You and Tony had been dating for a while now, and the past few months had found you spending more nights here with him, rather than at your own apartment. No one had been more shocked by the relationship than you, especially since your initial assessment of the older and richer man was that he was well-aware of, and confident in, his place in the world. A man who knew his own worth and...oh, to heck with sugar coating it. You had initially thought he was a prime asshole, with a capital A.

It wasn't until your social circles kept throwing you into each other's paths that you started to learn about the man beyond the narcissistic exterior. Sure, he was eccentric and an arrogant jerk at times, but he was also attentive and caring when he wanted to be. Once he realized you weren't sticking around for his money or to grace his bed for a night or two, he showcased a loving side of himself behind closed doors that the rest of the world wouldn't guess existed.

And the sex. Dear god, the sex! Your breath sped up a bit just thinking about last night's escapades, at how he had edged you until you were a begging, writhing mess beneath him, before sending you over the cliff and making you come again and again...and again.

He had quickly awakened a side of you that had previously lain dormant, making it his personal mission to discover all your secret fantasies and make them a glorious reality. Tony was a kinky motherfucker, and as it turned out, so were you. And yet, there was still one fantasy that you had hidden from him, one you tried to keep buried way down deep and struggled not to let show.

At the bottom of the stairs, you passed through his extensive security measures and stepped into the gigantic lab, rounding a corner towards the sound of grumbling. Tony turned around at the sound of your approach, still fully encased in the suit. The coffee cups almost fell out of your hand when the aforementioned hidden fantasy locked glowing eyes on you from across the room. Legs now quivering, you continued into the lab and shakily set the mugs down onto a nearby workstation.

Oh, had you forgotten to mention? Yea, the suit was your fantasy.

More precisely, Tony in the suit was your fantasy. You weren't sure when exactly this kink had started, but you had been strangely attracted to him wearing the Iron Man suit for a while now, and didn't know how to make it go away.

Part of the appeal was the psychological symbol of all it stood for: peace and safety for those who hadn't previously known such luxuries. There was so much power in that symbol, not to mention the physical prowess Tony had while wearing it. The virtually-indestructible superhero strength alone was enough to make your panties wet.

Then there was the design of the suit itself. Sleek, strong lines of metal that were shaped into the form of a man, yet also...it was just not human enough to make you shiver in a way that had utterly shocked you the first time it happened. The robotic mask with its stern-set mouth and glowing eyes sent a tingle of fear down your spine whenever they focused in your direction, but the fact that you knew it was Tony under there also gave that fear and intimidation an edge of desire. And it wasn't just the aesthetic of the suit that attracted you, but how Tony acted when buried within its grasp. He strode with arrogant claim into whatever arena he wore it, the power and confidence he exuded plain for all to see. And whether from the suit itself or the result of the authority he claimed while wearing it, the glistening gold mask also projected a slightly deeper, grittier version of his typical voice, one that could have you flat on your back and begging within seconds.

That same voice was now speaking in your direction, causing sweat to form on the back of your neck...and was followed by the snap of metal fingers inches from your face, jolting you out of the daydream you had been slipping into. Shit! You realized that he had been trying to get your attention for God knows how long, while you stood there practically drooling on yourself while fantasizing about him.

Real smooth, you have the 'keep this fantasy to yourself' routine down so well, you internally admonished.

Clearing your throat and wiping sweaty palms down denim-clad hips, you asked, "I'm sorry, what did you say?" Trying to act unaffected, you gave Tony what was hopefully a calm smile.

"I asked if that was coffee," he said, the suit staring at you so intensely that it almost made your brain go offline again.

"Yep, sure is!" you responded with an unnecessary amount of exuberance, mentally kicking your ass all over the lab for acting like a fool.

He stalked over to the workstation to pick up a mug, and you couldn't prevent the loud inhale, body frozen to attention, as he strode closer until he was well within your personal space. The mask fell away long enough for him to lift the coffee cup and take a sip, and in that moment, he locked eyes onto you with a knowing gleam, before the mask closed back up and he returned the mug to the table.

He knew.

Needing to get out of there, to get far enough away to calm your racing heart and panting breaths, you turned and started speed walking towards the staircase. You barely made it two steps before an unyielding metal hand wrapped around your bicep and twirled you back into the suit's massive form. Pushing your free hand against the sleek chest of alloy was futile, as Tony herded you backwards until your lower back bumped up against the workstation.

Goosebumps broke out along your arms when he leaned down, that glowing gaze inches from your face. Unable to stand their intensity, you closed your own eyes tight, a whimper escaping parted lips when a thick metal thigh pushed between your legs, effectively pinning you in place. Then that voice came from right above you, offering the choice of ecstasy or escape.

"Do you want me to stop?"

The logical part of your brain screamed at you to say yes, to get the hell out of there before this went too far down a path from which you couldn't retreat. But the other part...the one that had touched yourself to the fantasy of this very scenario more times than you cared to admit...that part was begging you to give in.

Suddenly, strong fingers gripped your chin and jerked it upwards, startling your eyes into flying open and locking onto that captivating gaze.

"I asked a question, sweetheart. Now, use your words and give me an answer."

Licking dry lips, you stared up at him in fascinated arousal and whispered, "No."

Head tilting slightly to the side, the grip on your chin didn't let up. "Sorry, I don't think I heard you properly. Try again."

"N-no," you said, voice louder but still shaky. "Don't stop."

As if that was all he needed to let loose, the hand at your chin fell down to join the other at your hips, fingers bunching into the hem of your shirt and jerking it up over your head. He didn't even bother to unhook your bra, just used the suit's strength to rip it right down the front and toss it to the side. You moaned at the sensation of your nipples pebbling into tight points against the smooth red and gold chest, his unyielding thigh still pressing up against the crotch of your jeans.

You yelped in surprise when one of his large arms swept out behind you, knocking both the coffee cups and assorted bits of lab equipment off the workstation. You barely registered the sound of breaking glass, head spinning when he lifted you up on the edge of the flat surface as if you weighed less than a feather. Leaning back onto slightly unsteady hands, you watched as he flicked the button of your jeans open and jerked them down your thighs, followed quickly by your panties being torn off, leaving you naked before him.

There were so many unique sensations, coupled with the knowledge that one of your wettest fantasies was about to come true, that your body felt overloaded to the point where you were already squirming restlessly and on the verge of begging. He groaned at the sight, powerful fingers gliding down your waist and suddenly squeezing into your hip so tightly that you gasped at the pain. "Careful," you whispered.

The fingers lessened, but only by a hair. "I wouldn't hurt you, sweetheart. At least-" He cocked his head consideringly, "-not more than you'd enjoy."

At that, the cool metal fingers drifted down so that both hands grabbed your ass roughly, making you groan and jolt forward as he stepped fully between your thighs and pulled you in against him. The length of him towered above you, both overwhelming and arousing in its reminder of how helpless you were against him...of how much you wanted to be taken.

The fingers of one hand glided up the front of your stomach, their surface so smooth compared to Tony's rough, work-calloused hands. They circled your breast lovingly for a few moments before changing pace and pinching your nipple hard enough to make you whine. The entire time those slitted, glowing eyes fixed intently on your face, measuring your reaction to each touch.

A sudden cry broke from your throat at the shocking feel of cool metal between your thighs, his other hand palming your cunt before dipping a finger inside and giving a few experimental strokes. Your head fell back between your shoulders at the deliciously taboo feel of him adding a second thick finger, thighs widening and hips arching upwards with invitation. He fucked you steadily, obscene noises emerging from both your mouth and cunt as his fingers scissored to stretch you out in preparation for his cock.

You groaned in disappointment when the fingers slipped away just as your orgasm was building to a peak. Your head lifted to voice a protest that quickly died, eyes widening when you caught sight of the large metal erection that was now hanging between the suit's legs. Licking suddenly dry lips, you stared at the thick appendage in awe and said, "I don't remember that being a feature of the suit."

He pulled you down the table until your ass hung off the edge, supported only by his hands. "It's a new edition I added, just for you."

Your face must've showcased your thoughts, because he gave a dark chuckle that caused an answering pulse in your cunt. "Oh honey, did you really think I haven't noticed how wet you get for Iron Man?"

You should've felt embarrassed, should've given some sassy retort. Instead, you gave an undignified whimper and arched instinctively into him when the stiff tip of his metal cock bumped into your clit before lining up at your dripping entrance.

Your mesmerized gaze was transfixed on the sight of him entering you, hands coming up to grip at the unyielding shoulders for stability as he opened you up with slow, steady thrusts. Gasping at the initial contrast of cool metal invading wet heat, your flesh quickly warmed him up and adjusted to the unyielding shape. He was buried so deep that you almost couldn't breathe, making you feel utterly dominated by his large form.

Clenching your hip with one hand, he braced the other one flat on the table before drawing his hips back, cock sliding slowly out before a quick snap of his hips slammed it back in. The movement was unexpectedly intense, Tony having underestimated the suit's thrusting power, and you cried out at the burst of pain-edged pleasure. He immediately froze, so attuned to your body after months of learning what each noise and response meant to know that he had pushed a bit close to your limits.

"Shit, sorry," he whispered huskily.

It took a few seconds to catch your breath, but then you let out a breathy giggle to let him know it was okay.

"Guess there's a learning curve to fucking in this thing," you teased, rolling your hips to let him know it was okay to continue.

"Guess it's a good thing that I'm a genius," he grunted with another thrust on the last word, this one less harsh but still deep enough to make you hiss and dig your nails against the inflexible crimson shoulders.

He continued that way for a few minutes, driving into you with just enough force to tinge the building pleasure with a tiny bite of pain. You reveled in it, in the way it made you feel claimed and his.

He suddenly straightened to his full height, causing your hands to slip back to the table for balance. His hands slid up to grab your ankles, anchoring your weight on them and spreading your thighs wide as he powered his hips in a deep, steady rhythm. That stern face stared down at you, and his strong grip left you powerless to do anything other than lay there and accept his unrelenting thrusts. Looking down, you gave a guttural moan at the sight of your juicing glistening along his metal cock, at how your pussy wrapped around his girth and accepted him over and over.

"You love this, don't you?" he taunted. "Next time you see Iron Man on TV saving someone, all you're gonna be able to think about is how it feels to fuck him."

The words ramped up your pleasure, sweat dripping down your temples as you lowered to your back on the workstation and moaned underneath that glowing gaze. And just when you didn't think the situation could get more intense, another little attachment popped out of an unidentified portion of the suit. It was a small, smooth cylinder, and you watched with curiosity as it drifted down between your legs and...landed directly on your clit...and started vibrating. Hard.

Keening at the sudden stimulation, you unsuccessfully tried to squirm away from the intense vibrations of the device. But the hands at your ankles and cock in your cunt kept you locked in place, forcing you to accept the overwhelming sensations. The pressure between your legs became almost unbearable, warmth suffusing your body as muscles tightened with impending climax.

"Yes, that's it. Come all over this cock. It was made for you, now use that pretty pussy to make it yours."

That was the final push you needed, the combination of the powerful thrusts, vibrations, and filthy words igniting the match of your orgasm, and the sparks crackled out from between your legs to engulf your entire body in flames.

He didn't stop, riding you through the pleasure until your legs were shaking so hard it was a wonder he didn't lose his grip. Nails clawed at the smooth surface of the workstation as you cried out his name over and over, until the orgasm died down to simmering embers and your voice lowered to a whimper.

Only then did he slow his movements, decreasing the pace until he came to a stop deep inside you, the clit vibe retreating into the suit as your walls continued to clench with aftershocks around the thick metal cock. When your thighs had stopped quivering and your eyes went from glazed to able to focus on him, he slowly pulled out, drawing one last full-body shudder out of you, as if your body couldn't help but protest the loss.

He pushed you up the table so that your hips could rest on the edge, legs dangling lifelessly over the side as you laid there panting, unable to summon the energy to move. Leaning over you, the front part of the mask parted and Tony's face came into view for the first time since he'd taken that single sip of coffee. His pupils were dilated and mouth slightly parted with his heavy breathing. When he leaned down to kiss you, your arms found the strength to lift and wrap around his neck, a spark of renewed desire igniting in your belly at the hungry way he laid claim to your mouth using lips, teeth, and tongue.

You gave a little squeal of surprise when you were suddenly lifted off the table and into the suit's arms. Striding through the lab, he beelined for the staircase. You looked up at him in question, and he curled up the sides of his lips in that trademark Stark smirk.

"Iron Man had his turn fucking you in the lab. Now, it's my turn to fuck you in our bed."

Suddenly losing patience with the boringly human method of walking, he used the suit to lift off the ground and fly up the stairs to the bedroom. When there, he proceeded to remind you that, while the suit was a fantastic sexual fantasy, it could never compare to the love of the man who wore it.
