Author notes: this is an AU version of MCU events that mixes MCU stuff with Marvel 616 Superior Iron Man. Peter is slightly older in this universe and didn't meet Tony during the events of CA:CW. It's also written to fit 5 bingo cards and a this-or-that challenge. The kinks/options in question are: hickies x's 3 (I had that on 3 different cards), Superior Iron Man, held down, lab sex
Summary: It happened once already, so why not a second time? Peter and Tony bump into each other again and go back to Tony's place.

Despite Tony's insistence that the one night would turn into more than one, it hadn't happened that way. In fact, Peter hadn't seen Tony or Iron Man around the city in better than a month. If it had been anyone else, Peter might've been really concerned. But, it was Tony Stark, the man with enough money to buy the American health care system if he wanted to. So, short of actually falling off the planet, Peter was sure he was fine.

Thus, when Iron Man showed up while Spider-Man was hanging out on a roof near where he'd just stopped a bank robbery, Peter wasn't surprised. Though, he may have been a little relieved to know Tony was okay.

"Miss me?" Tony asked, hovering above the roof in his sleek shiny metallic armor.

"No," Peter said back. It was true, but not as true as he wanted it to be. Or thought it should be. That was weird for him.

Tony put a hand to his chest. "I'm wounded. After what I did for you? I find it incredibly hard to believe that you haven't been thinking about it ever since."

The absolute audacity on this asshole.

"I have things to do. My whole day isn't spent thinking about your dick."

That made Tony chuckle behind that obnoxiously clear graphene faceplate. "Maybe it should be. I have a great dick."

Peter couldn't roll his eyes hard enough. "Shit, man. No wonder you had to move to Alcatraz Island, you needed the space for your damned ego."

"Stark Island, but I won't split hairs." He holds his arms out to his sides. "But, tell me, why wouldn't you think about this all day?"

"Your armor? It's cool and all, but maybe not as sexy and hot as you think."

Peter had never seen anyone frown so quickly. "Bite your tongue. This is awesome! It molds entirely to the shape of my body, but, unlike your fabric, mine is smart metal. Nothing's getting through this stuff."

The laugh from Peter's chest was so sudden and bright. "You truly are the most self-involved asshole." Peter shook his head. "Welcome back to New York, Tony. But, I got work to do." He got up, ready to go back to his patrol.

"Sure am. But, really? You're just gonna ditch me?"

"You're a big boy. I think you'll be fine. You don't need me to hold your hand."

"How about sucking my impressive cock?"

The eye lenses on Peter's suit widened as far as they were able to go. "Oh my god." He didn't know why something that direct from Tony shocked him that much. It really shouldn't have. Certainly not because Peter responded with, "You need me to do that or you just want me to?"

Tony narrowed his eyes. "I think it's a need. I haven't gotten a decent blowjob in at least a month."

"Been making do with bad ones?"

"At least you're not thinking I ran off saving myself for you."

If Peter didn't have the power to stick to things, he'd have been rolling on the ground laughing his ass off. "I wouldn't ever think that about you." Once he got his composure back a bit, he asked, "Where did you skip off to anyway?"

"So you did miss me. I'm flattered."

"Still didn't. So, where'd you go? Vacation? Business? Somewhere fun and exciting?"

Tony floated down closer to where Peter was standing. "I don't recall inviting you into my business." If Peter wasn't seeing things, the blue glow on Tony's suit almost flashed red for a second.

Peter reached out a hand and pressed a finger to the middle of Tony's chest like he was trying to push him away. "Chill, man. I'm just making conversation. And it's kinda weird you don't wanna say what you were doing. Like you think I wouldn't approve."

Tony glanced down to Peter's hand, then back up. "You probably wouldn't. Guess that means that blowjob's off the table, huh?"

Peter shrugged. "If you want me to sit on a table, that's your thing, I guess."

It was Tony's turn to be surprised. "Are you – do you think I would blow you?" He seemed to ponder that a moment. "Yeah, I probably would." He waved his fingers at Peter. "Come on. I've got a new lab to break in. And it's no fun doing that dance alone."

Peter folded his arms over his chest, taking a few moments to consider this option. It had been a hell of a lot of fun the last time. It could definitely be fun again. But, should he? Was it really a good idea to do this again?

"Hello – Parker? You're exhausting what little patience I might have for you."

"Sorry. Trying to remember if I left the stove on or not."

Flatly: "You didn't. Don't ask how I know that. Come on already."

First, he did want to ask how Tony would know that. Second, he knew he hadn't left his stove on – the thing didn't work anyway.

"Yeah. Okay. Fine." He stepped closer and wrapped an arm around Tony's waist.

"Your suit have good wind protection?" Tony asked, matching Peter's movement. "Because we're gonna go really fucking fast."

The answer: No. Peter's suit wasn't great wind protection. Not at Iron Man speeds. If he was ever going to do that again, he'd have to make some changes. He wasn't quite spitting bugs from his teeth, but he might have some windburn.

They touched down on the Iron Man landing pad and Tony lowered Peter to the floor. Peter tugged his mask off and followed as Tony led him inside. The place was enormous. Like, so much bigger than it seemed from the outside at ground level.

He'd been here once before, but he'd also been shuffle-rushed from the elevator to the bedroom so fast he hadn't had a chance to see anything. It had been the same on the way out too. Even now, he wasn't able to take it all in. Though, he could tell that everything felt very 'Tony'.

The furnishings and decoration was all crisp and minimalist-ish and vaguely modern and metallic. Or maybe that was just this floor with the landing pad.

Tony led him down a flight of stairs to a well-lit lab. Screens and lights lit up all across the room as Tony walked in. A smooth, feminine, computerized voice greeted him as well.

"Evening JOCASTA. Welcome my guest, Peter Parker. I don't know if I'll let him work on anything yet, but he can look around the usual areas," Tony said confidently.

"Of course, sir," JOCASTA responded.

Peter would need a little time to get used to talking to disembodied voices. Despite having a simple sort of AI on his cell phone, it was still kind of new to him. At least on his phone, it looked like he was talking to something, rather than the air.

Tony didn't seem to be paying much attention to Peter as he looked around the lab. If he ventured too close to something off-limits, a red light or a warning sound would activate. Since he didn't have access to much, there was a limit to what he could really explore – making investigating the lab not as much fun as he thought it might be.

It didn't take him long to get kinda bored, since he couldn't touch anything. So, he found a stool to sit on and pulled out his phone. If nothing else, he could play a few rounds of Angry Birds or something.

Peter was pretty engrossed in his social media feed when Tony came over to see what he was doing. So much so that Tony leaned down and started to nibble at Peter's neck before he was able to pull himself out of his hyper-focus.

"Mmmm – okay, that's kinda nice," Peter said, letting his head tip to one side.

"Just 'kinda'?" Tony might have sounded offended.

Peter shrugged. "You are just getting started. But, any chance you wanna nibble anywhere else?"

That wicked grin of Tony's appeared again. "Always. Tell me where and it's done."

"Everywhere, really. Just not my face. Collarbones, thighs, arms – let's see what you can do." That last part made his stomach tighten a little. He'd just challenged Tony to mark him all over his body using his teeth. That was stupid, right? He really should've thought that one through more.

Too late now.

"You're gonna want to take off the suit. Because I'm not chewing through that shit." Tony tipped his head toward a leather couch that was just starting to look a little worn in. If Peter was honest, it looked pretty inviting. Comfortable.

Peter stripped out of his suit – he didn't have his street clothes with him this time either – and folded it over the back of a stool. Tony's gaze on him made his skin flush. Which was typical for him. Close relationships like this made him nervous and excited. His history with this sort of thing was shaky at best.

The way Tony looked at him, maybe this would be different. Maybe it was different because they were skipping the emotions. Mostly.

Two steps in front of Peter, Tony turned around and reached to slide his fingers to the back of Peter's neck. "I need you to focus, kid. Stay with me here. But, you wanna tell me where it is you keep wandering off to? I'm starting to get a little insulted here."

Peter followed toward the couch as he answered. "Sorry. I – it's – it's not you. It's me." He settled on the couch next to Tony after the man sat down. "I know that sounds stupid. But it's true. I – my brain never seems to slow down. And I haven't had great luck with stuff like this. So, even when I try not to, I get worst-case-scenario thoughts. I don't think I'm trying to subconsciously sabotage anything, but, I don't know. I – I want to be here..."

"Stop. I'm going to stop you so you don't spin out of control." Tony pulled Peter up into his lap. "You're here and I am going to mark you up so good you won't want them to go away."

Peter shivered and bit his lower lip. He could get behind that. It sounded hot and fun. "Is that taking the place of any kissing?"

"You want to kiss me? I might be able to give you that soon."

What did Tony mean by that? Peter hadn't found it particularly odd that there hadn't been any kissing the first time – don't ask him why; it just didn't seem weird at the time. Now that they're doing this again, it felt a little off. Plus, he really liked kissing.

He shrugged. "It usually goes with this sort of thing."

Tony grinned. "For some." He slid his hands up Peter's sides, fingers tracing the bumps of his ribs. "Right now, I want a taste of your skin and to see how good it looks all marked up in bruises." Then Tony leaned in to suck and nibble at Peter's collarbone.

Lips first, then tongue, warm and wet. Suction working to bring blood closer to the upper layer of skin. Peter moaned softly; it actually felt pretty good as Tony got started. Peter even liked when teeth got involved. Tony didn't bite hard, just soft little pinches, and Peter could tell the patch of skin would be an angry red when the man was done. There'd also be spots of pink from the beard burn.

Peter balanced on his legs over Tony's lap, resting a hand on the man's shoulder when necessary. Teeth across his skin made his toes curl. A sharp pinch made his muscles tighten for a moment until Tony's long fingers would dip into his hair to help him relax. For a while, Tony just explored various spots on Peter's chest and arms, leaving red welts in each location.

Shifting so Peter was stretched out on the couch, Tony continued marking up Peter's skin. Across his stomach, over his hips, along his thighs, even one on his left calf. As he shifted to hover over Peter's chest again, Tony asked him to roll over – there was still more skin for him to claim.

Peter was so focused on the feel of Tony nibbling and nipping at his skin, he didn't even realize Tony had turned music on. Or maybe JOCASTA knew when Tony wanted music and cued it up. Either way, once Peter noticed it, he couldn't un-notice it. It was loud, industrial type music, but the volume wasn't turned up the way Peter typically heard people listen to it. It fit the mood too in a way that seemed to help him relax.

Tony licked a long line up Peter's back. "Mmmm, come back, Pete," he said and dragged his teeth over Peter's shoulder.

"Still here. My brain keyed in on the song and I was trying to remember where I heard it before."

"Campus? Dance club? Last time you were here? Obnoxious idiot on the subway?"

Peter laughed. "Probably any of those." He rolled his head back, rubbing it against Tony's shoulder. "What song is it?"

"What, do you plan to look it up right now?"

"No. I'll do that later."

"Song's called 'Negative Space'. I'm not telling you more because I have a lot of other things I'm going to do to you right now." He dragged his teeth down over the ridges of Peter's spine until he reached his ass. "I'll leave this alone so you can still sit comfortably. But, in the future…" Tony let that trail off as he slapped a hand against Peter's ass. "For now, don't move."

He wasn't going anywhere, but he was a little disappointed at the sudden lack of warmth against his back when Tony moved away. It didn't matter that he knew why. It always affected him that way – with anyone. He loved the feel of skin on skin, and the warmth of a body against his.

He was proud of himself for not making the little whimpering sound he could feel trying to escape. He didn't like that he wanted someone touching him that much. Needed someone touching him.

Tony's hand pressed against his back and Peter sighed into the couch. "I want to bend you over the back of this, but right now, I'm more interested in holding you down. Which one sounds good to you?"

Peter groaned softly. "Both sound good. But I'm good here. Press me into the couch."

He felt Tony's teeth on his neck. Just a warm bite, nothing sharp. His back arched up to press against Tony's chest, which seemed to make Tony bite a little harder.

"You ready for me, Pete?" Tony asked as he lined up the tip of his cock with Peter's ass. When Peter nodded and rumbled an affirmative, Tony pushed into him, harder and faster than he had the previous time. It was all Peter could do to gasp for air at the sensation. "Too much?" Tony added.

Peter shook his head. "No. Not too much." It had felt really good, in fact. As much as he had appreciated the slower, gentler approach the first time, he didn't want to be treated like he was fragile. Part of what drew him back to Tony was that he knew the man wouldn't bullshit him.

"Good," Tony rumbled. Then his entire focus seemed to shift to seeing how hard and fast he could fuck Peter there on the couch while pressing Peter's shoulders down against the cushions. It was perfect.

Part-way through, Tony drew back and said they needed to move to a new location. Peter, mistakenly, thought they'd be going upstairs or finding a bed. No, Tony shoved him down across a lab table and had a pair of robotic arms grasp Peter's wrists to hold him down against it.

They didn't lock into place, just held him. That was a relief, otherwise Peter would've been fighting to get out of there. Probably.

He was learning so many things about himself in just this one session.

And Tony was relentless. It was exhilarating. Peter didn't want it to end, but his whole body had other plans. His cock bounced against the table just enough with each thrust to shoot sparks across every nerve ending in his body. At this rate, he wouldn't even need Tony to touch him.

He was panting into the top of the table, moments away from begging Tony to go harder. Then Tony twisted his hips in such a way that if Peter had wanted to hold back, he wouldn't have been able to. His orgasm rocketed through his body and he came all over the floor beneath them. At nearly the same instant, he felt Tony get there too, spilling deep inside him, his hips stilling a moment later.

Resting his head on the table, Peter worked to catch his breath. He rolled his head and caught sight of a red mark on his forearm. Frowned for a moment, until he remembered Tony had spent nearly an hour biting and sucking marks into his skin. A little shiver skittered down his spine in anticipation of seeing all of them in the mirror.

Peter groaned a bit as he moved, his hips still pressed tight against the table. "Can I have my arms back, please?" he asked.

A large hand smoothed across the plane of his back, gingerly grazing the bruises he could feel forming there. "I'd really like to keep you there for a bit," Tony said, drawing out the end of the sentence, "but, I've still got work to do today and I bet you'd like a shower or something." Then there were two of those large hands skimming down Peter's sides. He liked the touches, but he really needed to stand up for a bit.

The robot arms released his wrists and rolled away silently. Peter started to lift himself from the table, only to find Tony's arms wrapping around him, those incredible hands moving over his chest. Peter couldn't resist the urge to lean back against Tony's body.

"You're gonna come do this again, right?" Tony whispered in his ear, one hand sliding down to cup Peter's cock.

"Um – do what?" Peter asked, his head still a little groggy from their recent activities.

Tony nibbled at his neck, which was not helping him stay focused at all. "Come back and play with me. There are so many more things I can teach you. Plus you wanted that collar, right?"

Peter's body was tingling, and not in that 'danger nearby, Spidey sense' way either. "Uh – maybe," he answered. "I'm – I'm kinda busy. But, if – if I can make time. Maybe."

"Good enough for me. But I hope that 'maybe' is more of a 'yes' because I haven't had this much fun with one partner in a long time."

Peter felt a little guilty that his immediate thought about that comment was 'yeah, right'. Though, he was pretty sure Tony was exaggerating to get Peter to make the decision Tony wanted. Either way, he was still going to have to do some assessing. He wasn't ready to commit to anything yet – even an on-again-off-again arrangement.

"I – I'll think about it." That was the best he could do. Even if he was already thinking about it and pretty sure he would be back if an opportunity presented itself. He'd have to be careful.
