A/N: Hey, so this is the first one of many Irondad one-shots I want to post. I'm going to try and update this with a new week at least once a week. Hope you enjoy!

Summary: Peter gets beat up by May's new boyfriend, because May's new boyfriend is Doc Ock and Peter is nosey. Tony just wants to work on a car with his Spidey son and send him off to college in one piece.

Peter stared at the car parts scattered across the floor. He tried to remember enough to start assembling, or to at least make a little bit of progress before Mr. Stark looked away from whatever he was working on and saw no changes were made. It was useless. He couldn't concentrate. Not on that. Not during that particular moment.

His thoughts belonged elsewhere, anywhere else, actually, but mostly not there. On the car. Completing the car meant completing a lie, or more importantly, led Peter closer to the moment he'd have to confess to Mr. Stark that he wouldn't be attending MIT in the fall and therefore wouldn't need this particular graduation present.

Peter had trouble deciding what would upset Mr. Stark more, his choice of school or that attending NYU rendered his gift useless.

"Every college man needs a car," he had told him, then proceeded to try and rush off to get him a brand-new Audi. Peter's lucky to have both May and Pepper. They were there to force him into a compromise.

May picked out some rundown car at a junk lot, and Mr. Stark would help him fix it up.

This compromise meant every Saturday that summer belonged to the workshop. He didn't mind that part. Spending time with Mr. Stark was one of his favorite things to do. Especially there, in the workshop, where new Iron Man suits were born. If Peter were really going away to Massachusetts for school next fall, which he definitely wasn't, he would miss him, almost as much as May.

The thought crossed his mind that he might end up missing Mr. Stark after all. Peter isn't completely above pretending to be at MIT while he really hung around New York. It sounded a lot better and like a lot less drama than giving him the bad news.

"You were right," said Mr. Stark. His voice dripped with sarcasm as he stood over where Peter worked, or pretended to work, on the floor. "Clearly you don't need my help."

"I didn't," he said, then frowned. "I don't. I'm just… distracted."

Mr. Stark's raised eyebrow demanded an answer.

"…Umm," said Peter. He picked the first non-college thought that popped into his head. "Well Aunt May has this new boyfriend."

"And you hate him."

"Well, yeah."

"Sounds about right," said Mr. Stark, with a sigh, as Peter checked his phone.

"Oh shit," he said, and struggled to get to his feet. He sprinted to the other side of the workshop, grabbed his bookbag from the floor, then sprinted back to Mr. Stark. "I'm going to be late. I'm supposed to be meeting him tonight."

He waited for the blow to come. A sarcastic comment. An ill-received joke. Peter prepared to defend himself for hating the man without ever meeting him, but the blow never came. This is something that, maybe, Mr. Stark understood, too. Peter didn't need a reason to dislike any of May's boyfriends, although he felt like he had plenty from overheard bits of conversations on the phone.

His name was reason enough. Doctor Otto.

Peter looked up once he adjusted the strap of his bookbag, and followed Mr. Stark's gaze over to the car, if it could even be called a car at that point, sitting in the middle of the room.

"At this rate it's never gonna be finished by fall."

"Sorry Mr. Stark," said Peter. "I'll come back tomorrow?"

"Nope, tomorrow I'm spending the day with Pepper," he said, then pointed at him. "Next Saturday I'm helping you, and cut it out with the Mr. Stark, alright? I told you. It's Tony. You're an adult now. Use your big boy words."

"Sure thing, Mr. Stark."

Peter was almost out the door when he heard Mr. Stark grumble, "Smartass."

He was, as predicted, late for dinner. He opened the apartment door to one of the most traumatizing sights he'd ever seen in his eighteen years of life. May and Doctor Otto were standing uncomfortably close, but worse of all, they were breaking apart, as if they'd been closer, as if they'd been kissing.

His eyes settled over the man, but Peter's feet stayed planted in the foyer, letting the door fall shut behind him. Doctor Otto was tall, with dark hair and fit. His button up shirt stuck too close to his skin, but that wasn't the most unsettling observation Peter made that night. It was the look in his eyes. Possibly, it was the same look Peter gave him as he sized him up, as the both of them were making up their minds about each other there in his aunt's apartment.

The apartment they used to share with his uncle Ben.

"You must be Peter," said Otto. He broke out of the kitchen and started across the apartment towards him.

"Obviously."

Otto looked taken back for a half-second, then quickly recovered and pretended he hadn't heard the tone. Behind him, May glared and mouthed at him to be nice.

"I'm Otto," he said. His grip was loose and flimsy, like a fish out of water or a man who's trying too hard to pretend to be unassuming. Peter knew better than to fall for that. "May told me so much about you."

"Really?" said Peter. "I haven't heard very much about you at all actually…"

"Peter," said May, marching across the kitchen and joining them in the foyer. She stood by Otto, on his side, and hooked her arm through his. "He's joking." She looked at Peter. "You're joking, but the joke's over now."

The couple walked back into the kitchen, arms still linked, and Peter swallowed misplaced stomach acid. His feet felt like dead weights as he followed them to the kitchen table. He didn't know how he would make it through dinner without puking, but he should at least try it. He should at least try to be polite even if Otto made his skin crawl and his stomach turn, just so May wouldn't kill him once he left. If he ever left.

He looked so comfortable on May's side of the dinner table, where Ben used to sit, Peter wasn't so sure they would ever get rid of him.

He stayed polite by keeping his responses as short as possible. He nodded when he could, he forced himself to smile, and occasionally, would make a noise that implied he was paying attention and actually, he was. Otto went on and on about his research with radioactive substances, maybe trying to impress him, but after spending so much time with Mr. Stark, it was hard to be impressed by someone so mediocre.

"I've heard you're pretty into science yourself," said Otto. There was a stray lasagna noodle hanging on his chin, and Peter had a hard time looking anywhere else. "I'll have to get your opinion on my work sometime."

"Oh," said Peter. He looked down at his plate and pushed a few noodles around with his fork. "I doubt I would have the time for that. I intern for Mr. Stark, and he keeps me pretty busy."

May narrowed her eyes at Peter, who stared right back. Otto was her boyfriend. It didn't mean he was obligated to spend time with him.

"I'm sure he does," said Otto, and Peter smiled for the first time since coming home, enjoying the bit of jealousy laced into his voice.

That night, Peter laid in bed and stared at his ceiling. The more his brain turned and turned and turned with all that talking about radioactive substances, about wanting to work with them, about AIs that would allow him to do it, the more it didn't sound right. AIs were dangerous in the wrong hands. Peter didn't think they should be trusted in the same hands that had trouble keeping food on his plate or in his mouth.

He didn't sleep until he resolved to start an investigation, and to not give it up until he found something so incriminating May would break up with him.

Peter had a simple plan.

He set his alarm early, at least for an otherwise lazy Sunday morning, and stayed in his room. He pretended to be asleep until he heard the shower water running. He slipped out of bed and made his footsteps light as he crept into May's bedroom. Her phone sat on the nightstand, and once in his hands, it was an easy hack. Something so simple and learned so easily by spending enough time around Mr. Stark, who was quick to teach Peter anything he wanted to know. He scrolled with his thumb until he found Otto's contact information, grinning when he finally came across what he'd been looking for, an address.

He sent it to his phone, wiped the message history and returned it to its original position on the nightstand.

By the time May came out of the bathroom, Peter sat at the kitchen table, watching YouTube videos on his phone and eating a bowl of cereal. The empty box laid sideways on the table.

"Good morning, May," he said, as she walked past him.

She headed to the coffee pot, or at least she had started in that direction. She backtracked several steps to stand in the kitchen entryway, observing him with her hands on her hips, until Peter was forced to acknowledge her.

"No."

"No to what?"

"To whatever you're up to," she said. "I know that look, and I know what it means."

"But I'm not even doing anything."

"Does what you're not doing have anything to do with Otto, by any chance?" she asked. Peter blinked at her, and she pulled on her we're-about-to-have-a-serious-discussion face while she pulled out the chair next to him. "Did you know all those nights you spend going off, having your little Avengers missions, I sit here in this kitchen, by myself, worrying to death about you? Every single time. It never gets less scary, but it always ends the same way. Do you know how?"

"Umm…" said Peter. He had a feeling he knew, but he felt like answering would be walking into a trap.

"With you coming through that door complaining," she said. "Mr. Stark is so over-protective. He's paranoid! He won't let me anything –"

"-My voice isn't that high."

"The point," said May. "Is that you are doing the same thing, with me, now."

Peter dropped his spoon, and looked at her, really looked at her. She made a good point. He hated that, because this situation was clearly different. Relationships were definitely more dangerous than his missions with the Avengers.

"I miss Ben too, but I have to start dating again sometime, you know?"

"I know," said Peter. "Does it have to be this guy, though?"

May rolled her eyes, stood up and headed to her beloved coffee pot. "Give him a chance, Peter."

"Okay."

It wasn't a complete lie. Peter would give him a chance, just as soon as he investigated and only if he couldn't find anything on him. He hoped he would. His aunt deserved someone better than the idiot who talked only about himself all evening with a noodle hanging off his chin.

His investigation started later on that same day.

Peter sat cross-legged on the top of Otto's apartment building while he ate his dinner, a slightly cold sandwich from Delmar's. He picked it up on the way over, with the intention of being able to eat it when he got home, but this stake-out was taking longer than he expected. It only served to prove Peter's suspicions. Otto was up to something nefarious. Obviously. There was no other reason for him to be away from his apartment all day long when he told May he was spending the day grocery shopping and doing laundry.

He waited hours on that rooftop, watching the city below him and listening to all its sounds, only to finally tire out and head back home empty handed. Without any evidence. He hadn't been entirely sure what he expected to find there, anyway.

Peter crawled through his bedroom window, then heard it. He ditched his suit for regular clothes and discovered the reason Otto hadn't returned home to his apartment. He was here. On the couch with May. Watching a movie with his arm around her.

"Oh hey, Peter," said May. She paused the movie, and both pairs of eyes stared him down. "I didn't know you were home. Do you want to watch this with us?"

"He probably doesn't have the time," said Otto. It was lighthearted, but it grated at Peter's nerves.

He dismissed himself. Politely. He could foreign politeness just as well as Otto could pretend to be meek.

Peter paced in his room. Back and forth, back and forth, thinking fast and frantic. He stopped when his thoughts did, when his he lifted his head from staring at the floor and his eyes fell over to his desk drawer. A new idea, like a spark, sent him barreling to his knees in front of the drawer. He yanked it open and searched through it, pulling out papers and graded homework from years before as it did.

But it was useless. They were all gone. A tracker would have been perfect, would have done his job for him, but they weren't anymore left. Not in his drawer, or in his suit.

There was one more option but asking Mr. Stark for more trackers invited his questions. He collapsed on his bed, realizing he didn't have much of a choice, and put his scheme against Otto off until Saturday.

It rolled around fast, and Mr. Stark hadn't been kidding when he told him he'd be helping him this time around. Within five minutes of his arrival at the workshop, the two of them were side-by-side, shoulders nearly touching, face-up underneath the frame of the car. He passed him tools, explained to him what did what, and what to screw and where. It was almost like having a dad again, and it pushed Otto and the tracker to the very back of his brain.

He just wanted to enjoy the moment.

But when there wasn't May and her boyfriend to worry about, his mind reverted back to worrying over the moment he confessed to Mr. Stark MIT wasn't happening.

Thinking about not going ached like regret. He wasn't just disappointing Mr. Stark, but himself. As fall got closer and closer, he realized more and more MIT was the perfect place for him. He didn't understand how Mr. Stark knew that long before Peter, but none of it mattered. It didn't change anything. He still couldn't go.

He already declined the offer, and there were two very good reasons that went into that decision. The first was Queens. His city still needed Spider-Man. The second was more important. He couldn't leave May. Who else would investigate and stalk her boyfriends, or eat Thai food on the couch while watching trash reality TV?

A nudge on his shoulder broke him out of his thoughts.

"Let's take a break," said Mr. Stark. They both scooted out from under the car and sat up. Mr. Stark threw a rag at him. Peter used it immediately, wiping off the black smudges he felt on his cheeks, then his hands. "How's the situation with May and the new boyfriend?"

"His name is Otto," said Peter. "He's a tool."

"Otto, huh? No wonder why you don't like him," Mr. Stark stood and walked over to a stool where his phone sat, leaving Peter to sit on the floor, using his hands as props to support the rest of his body.

Peter stared at the back of Mr. Stark's head while he strolled through his phone. He figured it was now or never. To ask about those trackers, not for the college confession. He still had a couple of weeks until he would need to disclose that information, and he planned to procrastinate as long as possible. He found his voice, though it wavered when his request was said out loud, causing Mr. Stark to turn around and look away from the phone in his hand.

"Why? What for?"

"To track… someone," said Peter.

Mr. Stark tilted his head at him. Forget being trapped under buildings. He was eighteen years old and one look from him turned him back into a guilty first-grader. It ruled out the possible scheme of pretending to be in Massachusetts in the fall. He'd never be able to pull that off.

"I got that," he said. "Who?"

"No one important."

He made a face like he didn't believe him but walked away and returned with a handful of the tiny trackers despite his unanswered questions. He passed them to Peter, who had to stand to collect them. He shoved them in the smallest pocket of his bookbag.

"So, what is it this time?" he asked. "Man who thinks he's a bird? Another lizard guy?"

"Nothing that like."

He made the same face. It was every bit pinched as it was disbelieving, as if there were questions beating down a wall in his mind. Old Mr. Stark didn't have that wall. He wouldn't sat him down and demanded to know exactly what the trackers were used for. New Mr. Stark, who was inspired either by Pepper or a therapist, maybe both, let it go. He asked questions. He pried, but he didn't stop him from making his own mistakes.

Sometimes Peter missed the old version. He felt less guilty about lying to helicopter Mr. Stark.

"If you're ever in over your head," he said. He twirled a screw-driver in his hand. "I'm just a phone call away."

Peter looked at him, really looked at him and saw the scruff, dirt and grime instead of the billionaire wearing a suit and sunglasses. It was the workshop effect. Everything became a little more real, a little more transparent under the grease and dust, and under the dim lighting, Mr. Stark was just someone who worried too much about the people he loved.

And also, someone who was getting better and better at heaping on the guilt without even trying to do it.

The golden opportunity to put a tracker on Otto presented itself later on that same evening. Him and May were close on the couch, in their usual positions, as Peter stomped through the living room, still covered in the grease and dust of the workshop and swallowing another bout of stomach acid. They didn't notice him, so he didn't even try to be discrete when he slipped a tracker inside the seams of Otto's coat.

He shouldn't have left it out in the open like that. Just hanging on a kitchen chair.

After that, all he needed to do was wait, and he didn't even have to do that for very long.

Otto excused himself from their movie night unusually early. As soon as Peter heard the apartment door shut, he pulled his mask on and watched the blue dot which represented Otto move across the map. It didn't go to the dodgy apartment building where he lived. It went to the labs where he worked. Awfully late to be going to work. Unless that was his angle. To access the lab when the rest of the employees weren't around and couldn't see what he was doing.

Only one way to find out.

He suited up and followed the beacon to the labs. He was done pretending to be polite, so slamming through one of the windows and shattering glass everywhere as he tumbled into the building didn't seem like an imposition. No alarm sounded, either, which was an added bonus.

The last thing he needed was for him to be tipped off about Spider-Man's arrival.

He followed faint noises to find Otto, and when he got to the room he was in, he crawled up the wall and stuck to the ceiling, watching upside down as Otto maneuvered around the lab, unaware of his presence. Nothing seemed special. Nothing seemed to catch Peter's eyes, until Otto walked over to a place in the lab he wouldn't have known to look if he hadn't gone over there.

He strapped himself into a harness, and from that harness, gained four new arms. Mechanical ones, with claws at the ends of them, and they were snapping. It concerned Peter that all four of them were extending upward, in his direction, but in retrospect it probably should've concerned him a little bit more. It just took one sudden movement, one metal tentacle shooting up fast and abrupt inches from where Peter hung to send him somersaulting to the ground.

He stuck the landing with his shoulders stuck out for balance, and looked up, looked into the eyes of Otto Octavius and saw the same something nefarious he saw the first time he met him. Granted, it was hard to take seriously with four mechanical claws floating around and snapping at him.

"What are you supposed to be?" asked Peter. Maybe Mr. Stark wasn't too far off with his guesses that had to do with animals. "An octopus?"

"Glad you could finally find the time to join me, Peter."

"Wait, what –"

"You're really not that great at keeping secrets," said Otto. His eyes drifted off to the equipment to his left, then back to Peter. "So, I'm sure you'll understand this isn't personal. I just can't have you running off and telling Iron Man about all this."

It was over before it started. While Peter was busy looking at all the things Otto didn't want to Mr. Stark to find out about. He didn't know what they were, or what they did, or why it would mean trouble for him if Iron Man discovered it, but that didn't stop him from attacking.

Fast and abrupt just like the first time. He managed to dodge the first, but the second caught him in his belly and swatted him against the wall. He crashed to the floor, awkward and ungraceful, and thanks to his upgraded hearing, could hear the bone in his leg snapping before he even felt it. But the pain did come and distracted him from the third metal arm that lifted him up and pinned him against the wall.

It was Otto's real hands that punched him, hit him hard in the stomach, on the face, but all Peter felt was the pain in his leg. He kept his focus there when the punching stopped, when Otto's hands came up around his neck and cut off his air supply.

He was about to get killed by a man who couldn't eat without getting food on his face.

That's when he heard it. The gloriously familiar sound Iron Man made when he hovered, followed by his voice.

"Get your grubby tentacles off my kid, kraken."

Peter was dropped to the floor, on his pitifully broken leg, but he felt better than fine. For all the aches and pains, even the stabbing one in his leg, he knew this was a fight that wouldn't last long, either. There was no stomach acid as he watched Otto attempt to smack Iron Man around with those ridiculous metal arms. Mr. Stark wasn't distracted, was ready for it and simply blasted him away with his repulsor beam. He flew across the room, crashed into the wall the same way Peter had and thudded to the floor.

Mr. Stark wasn't done, though, even if Otto was no longer in any condition to fight. He didn't stop until every single one of the metal arms were disbanded, snapped in half or otherwise disposed, and it isn't until Otto is knocked unconscious that Mr. Stark lands next to Peter.

"Mr. Ssstark –" said Peter. "I - I didn't call."

"Yeah, well, you're just lucky you weren't the only one tracking someone tonight, kid," he said. He kneeled down next to him. "What's the damage?"

"Leg's broken."

He felt the pain then, all at once, as if saying it out loud made it present. He gasped, and Mr. Stark winced. He turned his head, leveled another glare at Otto, and for a second, Peter thought he might go back over there, kick him while he's down and unconscious, but the moment passed. Mr. Stark wrapped his arm around Peter's shoulder's, and very carefully, put his other arm under his legs, eventually scooping him off the ground.

Any energy he usually would have spent protesting being carried is focused towards the pain radiating throughout his body. He shut his eyes and hoped to pass out while they went soaring into the night's sky.

They put him on painkillers.

Mr. Stark's medical team were quick about that one, and the drugs were fast. They were both speedy and strong. He didn't remember much about the process of having his leg set and casted, but he did remember voices murmuring up above him. He couldn't quite hold on to them, but they were talking, amazed, about his healing abilities. It would take just a couple of days for his leg to be back to normal, and less than that for the bruises to disappear.

Until then, however, he was laid up on Mr. Stark's couch. His leg was propped up, in a blue cast and there were lots of pillows supporting his back, so he could sit up without effort. Everything came back into focus. The blurriness in his head cleared up as the pain started to trickle back in. Then he remembered.

He had just one concern.

"I need to call May," said Peter, and to his shock, a voice answered back.

"Already done."

He slowly, carefully, turned his head and saw Mr. Stark in the recliner, staring at him.

"Don't worry," he told him. "I broke the news to her about the octopus, too."

"Is he –"

"-He's alive," said Mr. Stark. "Uh, he just won't be doing very much for a while, and he definitely won't be calling your aunt back."

Relief flooded through muscles that should've ached. Mission accomplished, but it didn't feel as good as he thought it would. It sort of sucked, actually. That May started dating again just to get stuck with Otto. That her happiness got delayed again. It only served to reinforce his already made-up about staying in the city for school.

He looked at Mr. Stark. It was the perfect time for the truth about college. While he was drugged out and the consequences didn't seem as bad, and while he was bruised and broken to the point Mr. Stark would feel guilty if he started to yell.

"I have to tell you something," said Peter.

Mr. Stark looked up from his phone and didn't miss a beat. "I already know you think you're not going to MIT, Peter."

Maybe it was still the drugs, but he didn't quite catch what was said, or at least the implication behind what was said.

"W-what?"

"You're a terrible liar," he said. "And I knew you would end up getting cold feet, so I paid someone at the admissions office to keep an eye out for your acceptance status. When you declined, idiot move by the way, I just had the evidence destroyed and sent in the deposit for your first semester instead."

It was said so simply. As if it were completely normal behavior to employ spies at a university, and as if semesters at MIT were cheap. This was helicopter Mr. Stark. He never really left. He just tried to change during the moments that really mattered, or the ones that didn't. Peter couldn't figure out which way it went, but either way, he felt the only appropriate reaction was anger. Only as much anger as the medication would allow, though.

He still felt pretty fuzzy.

"…you can't just do that," said Peter. "You can't just accept on my behalf and force me to go."

"Sure I can, I already did." said Mr. Stark. He leaned back in the recliner. "Tell me that you really don't want to go. Convince me, and I'll pull my deposit and put it towards a school closer to home."

Peter didn't say anything. He couldn't. He, apparently, wasn't capable of lying even without the drugs, so he didn't see a point in trying. All that was left was the truth.

"I can't leave May, or Queens."

"Your aunt is more than capable of protecting herself," said Mr. Stark. "And you know she wouldn't want you to sit out of college her behalf. She would never forgive herself, and besides, I'll still be here."

"Spider-Man –"

"-will take a break."

Peter didn't attempt anymore arguments. There wasn't any Mr. Stark wouldn't easily counter, and there wasn't any energy left in him to try it. He was going to MIT in the fall. It was inevitable now, and different, because he could blame Mr. Stark for it every time he felt like it was selfish. It was a better gift than paying his tuition, really. That he could go to the college he wanted and push all the guilt on Mr. Stark for manipulating the situation.

He'd still feel bad about leaving Aunt May, of course, but he figured Mr. Stark was right. She would feel bad if he didn't go, and he'd end up feeling terrible either way.

The conversation was officially over, so Mr. Stark provided him with more painkillers, a cold-pack for his swelling eyes, a glass of water and a demand for him to get some rest. The pills made him sleep, and when he woke up, he felt better. Still hurt, but better than the night before. Well enough even to get up and try to move around on the crutches.

He found Mr. Stark in the workshop and stopped, sudden and shocked, at the shiny car sitting in the middle of the room.

"Mr. Stark," said Peter. He leaned on the crutches, putting his full weight there instead of his good leg. "How long was I asleep?"

"Just the night," said Mr. Stark. "And half the day. Why?"

"What is that?"

"Your car," he said. "Don't you recognize it?"

"No. This… this can't be the same car."

The car they'd be working on was rusty and falling apart despite all their effort. This one looked new and fast.

"Maybe I put some custom parts in it," he said. There were a few seconds of silence. "Maybe I put a lot of custom parts in it."

"May's going to flip."

"She's not going to be thrilled about those bruises, either, genius, but I figured it'll be better if we get it over with all at the same time."

Peter nodded, and Mr. Stark was correct. She wasn't thrilled with his broken leg, or his black-eyes and bruises. He had returned to the couch in the penthouse living room when she arrived. She sat next to him, looking him over, and apologized.

"I should've known," she said. "I'm so sorry, Peter."

Hearing her apologize hurt worse than any of his injuries. This one was Peter's fault. Otto turned out to be crazy only by chance. He only stumbled into some scheme he didn't even understand, and next time, he knew that wouldn't be the case. That eventually May would date someone normal, who wasn't Ben, and he'd have to accept that, from miles away in Massachusetts.

Thanks to Mr. Stark's meddling he didn't have much time left in Queens. Just a few weeks.

"I'm sorry too," said Peter. "I promise I won't go all Mr. Stark on you next time you date someone… unless there really is –"

May narrowed her eyes.

"I promise I won't stalk your next boyfriend."

"That's all I can ask for," said May. She looked around the big, empty living room. "Where's Tony? He said he had something to show me…"

Peter happily directed her to the workshop, happy for once someone else was in trouble and not him. That he had nothing to do with the under authorized upgrades on his graduation present. He watched her disappeared into the elevator, preferring the couch over front seats to seeing May berate Mr. Stark about the car. He needed the rest to heal, and anyway, he was pretty sure he'd be able to hear the shouting that he knew was coming.

A/N: Thanks for reading!
