Warm water cascaded over Peter's head, down his body, and onto Tony's head. Peter struggled to keep his eyes open, rapidly blinking water from them so he wouldn't miss a moment of watching Tony's mouth slide up and down his shaft. His knees were weak, so he leaned back against the shower stall, his fingers loosely tangled in Tony's hair. For a moment, he was convinced this wasn't real, that he had delved so far into a daydream that he could no longer separate fantasy from reality.

Tony's lips tightened on Peter's shaft, and Peter let out a deep groan, struggling to keep from forcing his hips forward. Tony ran his hands up the backs of Peter's legs and massaged his ass before pulling his hips flush against his face. Peter threw out a hand to catch himself against the shower wall, a strangled gasp escaping at the feeling of being fully engulfed in Tony's mouth. Tony sucked harshly, the head of Peter's cock pressed into the back of his throat.

Peter's ex-boyfriends had never been so giving, so he'd been surprised when they'd stepped in the shower and Tony had immediately sunk to his knees. "I've been dying to taste you," Tony growled. He stuck out his tongue and let it lave the cockhead as Peter grew thicker against his tongue.

"You don't have to," Peter had said, his half-choked words belying his wish that Tony continue.

Tony had glanced up then, his brown eyes searing through Peter and causing his breath to catch in his chest. Water ran down Tony's face, catching on his eyelashes. His voice was husky as he said, "Trust me, Peter. There's nothing else in this world I'd rather do."

And so Peter had leaned back against the cool shower wall and succumbed to absolute pleasure. Tony's hands continued to knead his ass, alternating between firm strokes and tender caresses. All the while his mouth continued to suck and work at his cock, occasionally pressing his ass to force Peter's hips against his nose, taking him as far down his throat as he could. Drool dripped down Tony's chin only to be washed away immediately by the shower.

Tony's hands spread Peter's globes and a finger came to rest gently against his hole. Staring up at Peter, he asked, "May I?"

Words caught in Peter's throat, and he could do no more than nod and press back against the finger.

Tony took Peter back in his mouth and lightly dragged his finger along his crack. He tenderly probed at the hole, but without lube, he didn't want to risk inserting his finger past the first knuckle.

"Turn around?"

Expecting a cock to press at his entrance, his exes having been semi-negligent with prep, Peter shouted in surprise when he felt a tongue run against him. "Oh!" he cried out, shoving his ass backward toward the sensation. He had never been rimmed before and was quickly overwhelmed.

Tony smirked at the noises he was pulling from Peter, so much better in person than they had been over the phone. He alternated between using the pad of his thumb to press against the hole, teasing it, and using lips and tongue to suck at it, determined to unravel him. He dove in ravenously, wishing he had lube so he could really work him open. Instead, he settled for thrusting his tongue as deep as it would go, his beard scratching against tender flesh as he did so.

Peter's legs were shaking before Tony pulled back to give him a chance to breathe. Peter's chest heaved as he pulled in deep breaths. Looking up, Tony admired the flush receding down his back and nearly reaching his legs.

"You're so beautiful."

Peter turned over his shoulder to look down at Tony, his brown eyes hazy and barely focused, and Tony felt his heart catch in his throat. What had started as one night of intense passion with a stranger had morphed into an obsession and was now…what? What could Tony call what they had? He clearly had a physical appreciation for Peter, but he also had a newfound respect for Peter's brains through his contributions to the arc reactor project. How far did they both want to take this?

No use dwelling on this now, not while he could be otherwise occupied.

Tony settled back in with his mouth and reached around to take Peter in hand.

"Tony," Peter moaned, his voice breathy with the intensity.

Moving lower, Tony mouthed at Peter's balls before running his tongue back up the perineum and into his hole. Meanwhile, his hand continued to work Peter, experimenting with his grip to see what would draw the loudest moans from Peter. He could feel precum gathering at the tip, but it was quickly washed away by the shower. Driven by a sudden desire to taste him, Tony directed Peter to turn back around so he could take him back down his throat.

He glanced up at Peter and froze at the sight of his blissed out expression, his eyes squeezed shut and mouth partially agape. By now, the chlorine had been thoroughly rinsed from Peter's body, and the water was starting to chill. Tony stretched to shut off the water and watched as Peter blinked the drops from his eyes.

Tony guided Peter's hands to the back of his head. "Here's what you're going to do, baby boy. I'm going to put you back in my mouth, but I'm going to leave the pace up to you. You ever fucked someone's throat before, sweetheart?"

Blushing, Peter glanced away. "No." He bit his lip to keep himself from mentioning that this was only his fourth receiving blowjob ever, his past boyfriends having rarely reciprocated. He was certain Tony wouldn't judge him, but he wasn't sure how wise it was to discuss past flames with his dick in someone's mouth.

"You won't hurt me," Tony assured him. "Start slow and keep your hands loose enough that I can pull back if I need to. As you speed up, if I need a break, I'll tap you on the hip, like this."

Peter stared down at Tony on his knees, his lips loosely wrapped around his cock. The wet heat felt incredible, and Peter's hips twitched forward in their own accord. Tony gave an encouraging moan, so Peter did it again more purposefully. The slide in and out of that mouth was blissful, and Peter gripped Tony's head a little harder. Tony kept his jaw loose, and Peter found it was easy to develop a rhythm.

Tony wrapped his hands behind Peter's ass and pulled until his nose was pressed into Peter's pelvis, the head of Peter's cock pressed against the back of his throat. He moaned as best he could with his mouth full. Sucking dick had always turned him on more than anything had a right to, and he stroked himself roughly to the feeling of Peter's hard, hot cock pistoning in and out of his mouth.

Tony's knees were sore by the time he heard Peter's breathing hitch and his thrusts began to lose their rhythm. He pulled back, closed his eyes, and opened his mouth so his tongue was outstretched. "Come on my face, Peter."

Peter fisted himself. His eyes were squeezed shut, but the image of Tony before him on his knees was seared into his retinas. He could feel a great tidal wave welling up inside him, threatening to crash over him and pull him under. His strokes were erratic, his arm trembling.

The first white wave hit Tony on the chin. He groaned, his hand speeding up to reach his own orgasm. The second wave hit his cheek while the subsequent waves didn't make it past the end of Peter's fist. Peter's eyes opened just in time to watch Tony's tongue stretch as far as it could to his cheeks and chin. Tony was still blissed out, teetering right on the edge. Peter stepped back so he had a better view of Tony's hand jerking himself. Within moments, his face contorted before relaxing into a smile as he came.

After catching his breath, Tony stood up and turned the shower on so they could rinse off. He smiled easily at Peter, reaching out to touch his arm, his chest, his stomach. "That was so much better than I could have imagined," he purred.

Peter preened under the words, and he reached out to tangle his fingers in Tony's. "I wouldn't mind getting you on your knees again."

"I'd spend my whole life on my knees before you, gorgeous." He nipped the shell of Peter's ear before turning off the shower and wrapping them in the hotel's towels. "And I wish I could, but it was already hard enough for me to sneak out here. I'm sure Happy's hunting for me."

And just like that, the glass casing of their fantasy world was shattered and Peter was struck with the reality of their situation. This was his boss he snuck off with for a quick fuck in a hotel bathroom. It was bad enough they had already found themselves in an ethical dilemma at Bottom Feeders, but Peter kept returning again and again. Was it really worth it to put his entire career at risk to sneak around with the CEO of his company?

The image of Tony on his knees, tongue eagerly seeking Peter's seed, would forever be burned in his memories, and Peter realized he'd risk it all again given the chance.

Happy met Tony in the hallway outside his room, and he did not look…well, happy. Tony put on an air of casual ignorance, but he knew Happy wasn't fooled.

He should have realized it was a trap when Happy didn't immediately start into him. The door was halfway open before Tony noticed the complete drop in temperature, but by then, Happy was shoving him the rest of the way into the room and closing the door to block his escape. His temporary roommate was nowhere to be found, and in his place was—

"Pepper."

"Tony."

Her voice was the chill breeze of the Arctic tundra, rooting Tony in place. His brain worked at a mile a minute trying to come up with an exit strategy. How much did Pepper really know?

Clearly a lot if she had flown all the way out from New York City to meet him in his hotel room.

His normal strategy with Pepper was to try to talk his way out of his messes, but from the leveled look on her face, he thought for once in his life he should wait her out and let her reveal how much shit he was truly in.

"Tony, you promised you wouldn't use this trip as an excuse to sneak off with your employee."

"Actually, what I promised was that I wouldn't build a particle accelerator as an excuse to sneak off with Peter, and technically I never said the words 'I promise.'"

Ah, fuck. His vows of silence never lasted long.

Pepper's scowl drained away to be replaced by fatalistic acceptance. She poured herself onto the bed, her icy countenance having melted into water. "Tony…" She sighed and wearily rubbed her temples. "I know ethics has never been your strong suit, but this really is way over the line. Gladys has already turned a summary of the inquiry over to the U.S. Equal Employment Opportunity Commission—which you'd already know if you actually read your emails. If you've had any sexual contact with that boy since—"

"Peter." Tony's voice was barely above a whisper.

"What?"

He cleared his throat and cocked his chin proudly. "His name is not 'that boy.' It's Peter."

What had once been a melted puddle was soon a roaring furnace. Pepper rose from the edge of the bed, glowering, and prodded Tony's chest with her finger. He took a step backward instinctually and noted his back would be pressed to the wall a lot sooner than he'd like. "Peter," she snarled, "is the name of your employee who you've been explicitly told to stay away from. All it takes is for him to make one accusation towards you, and—"

"He wouldn't do that!" Tony protested. "We—"

Too late, Tony clamped his mouth shut.

Pepper shoved him.

Tony stumbled, surprised. Pepper had lost her temper with him plenty of times, but their fights usually ended with her exasperatedly throwing her hands in the air and Tony buying her anything strawberry as an apology gift, knowing full well that she was allergic. Never had she laid her hands on him. Never had he seen her so mad.

"You slept with him, didn't you?" she shrieked, her fiery hair shaking loose from its bun in her anger. "Like a child, you were told 'no,' and you just had to do it anyway! Well, Tony, this wasn't another game to be played. This is your company at stake! And you threw it all away for a one-night stand with an employee twenty years your junior! I hope he was worth it."

Tony stood his ground and drew himself up. "He was worth it. He is worth it. Pepper, this wasn't a one-night stand. At least, not for me. And…I don't think for him, either."

Pepper deflated. "Oh, Tony… My hopeless romantic… What am I going to do with you?"

Tony wasn't in the lobby to greet them the following morning, and Peter felt a surge of panic. Did Tony regret what they did? Was he already on his way back to New York, ready to ditch a multi-million dollar project just so he didn't have to face Peter the morning after? He thought about asking Happy where Tony was, but the hardened glare Happy sent him had him shrinking behind Bruce and Hope.

Luckily, Stephen was first to bring up the subject. "It's bad enough Tony kicked me out of my room last night, but now he's not even here this morning?"

Stephen's complaints continued, but Peter's racing thoughts drowned him out. What did he mean that Tony kicked him out of his room? Did Tony meet with someone else after his time with Peter? Did they have sex? Did he mean so little to Tony that he was barely a side piece?

"Calm your thoughts, Peter," he chided himself. "Don't get worked up over nothing. I'm sure there's a logical explanation."

And there was. When they arrived at Fermilab, Tony was already there, his assistant Pepper at his side. Tony's sunglasses were back on, hiding his expressive eyes, but Pepper's face had no problems letting Peter know exactly what she was thinking.

It was all well and good to sneak around with Tony and pretend the world was frozen around them, that their actions had no consequences, but it was quite another to come face-to-face with the harsh reality that was Pepper Potts boring into your soul and reminding you of all those hours you spent in your business ethics seminars the first few weeks of work. Was getting a blow job from your boss worth the possibility of getting fired?

For Tony? Peter realized he'd watch the world burn for Tony Stark.
