Requested by sophie_louise26: Peter and Y/N are dating, and Y/N is Tony's daughter, so she works at the Tower. One day, Peter's school takes a field trip to the Tower, and he gets pulled away by Y/N who wants to make out with him. But halfway through, Peter's class accidentally walks into them.

I sat in my dad's lab, my eyes glued to the circuit board in front of me as I carefully fixed it. My tongue was sticking slightly out from in between my lips in concentration, my hands calmly holding still as I soldered the wires together to fix the board that had protected Peter's heart from being shot. That was the part that I hated about it. I nodded to myself as the solder stuck the wires together and fixed it, my posture straightening back up as I put the soldering iron back into the stand. My eyes flicked down to my phone as it buzzed, my heart fluttering in my chest as surely enough, it was a text from Peter. Speak of the devil, I thought to myself as I picked up my phone and started to type out a response to my boyfriend of two years now.

Peter: You fixed my suit yet so that I don't die? ;) xxx.

Y/N: If you were more careful, I wouldn't HAVE to save your ass every time ;) xxx.

Peter: Touche, baby. Excited to see you today. Even if I can only admire you from afar xxx.

I smiled and bit my lip, Peter never failing to make my heart flutter as my eyes looked over the text. I was the daughter of head Avenger and billionaire, Tony Stark, and I had been dating Peter since the boy had joined the team, two years ago. I didn't have any powers, but I had inherited my father's ability to be incredibly gifted when it came to technology, and so I had been given the vital job by my dad of fixing everyone's suits when they were seemingly damaged beyond repair. Because, and I was beyond proud to say this, even my dad couldn't fix them at that point. And yet, I could. But then Peter had come to me and very sheepishly told me that his suit needed fixing because he had taken a bullet to the space over his heart. To say that I had been livid was an understatement, but at least my boyfriend had lived, and his suit had now been fixed by me too. Now, given who I was, I didn't go to his school, but today, his school would come to us. Peter's science class was coming to the Tower today in order to look at our labs, and of course I was excited to see the love of my life. But the one thing was that because no one knew that Peter was Spider-Man, apart from his two best friends, no one knew that we were dating. Hence why Peter was going to have to 'admire' me 'from afar', as he put it. But still. At least I would get to see him.

"Pete got you smiling that much, kiddo?" I looked up, my dad raising his eyebrow at me and giving me a smug smile as he walked into the lab.

"Fuck off." I retorted. He smirked and shook his head, my fingers clicking my phone off as dad sat down next to me at the workbench and looked down at Peter's suit.

"You fixed it, kid?" He asked as his eyes flicked over the wiring.

"Of course I did, dad, it's me." I smiled as I looked at him.

"You're too arrogant for your own good." He returned.

"I wonder who I got that from." I teased, making him chuckle and shake his head as he jokingly nudged my shoulder with his own.

"You know that Peter is coming with his class today, yeah? And you know that you can't really let on that you know him?" He checked as he looked at me. I sighed and returned the glance, my heart hurting slightly at that fact. I wasn't to be mistaken, I knew why Peter had to pretend not to know me when he was with others, but that didn't mean that it was easier to deal with.

"Yeah, dad. I know." I nodded and playfully rolled my eyes at him. He gave me a small smile and cupped my cheek, making me sigh as I went back to soldering Peter's suit.

Peter's P.O.V

"Oh, look, we're at the home of Peter's girlfriend, Y/N Stark! Look, Penis Parker, your girlfriend is up there!" Flash teased as Peter, MJ, Ned and the rest of their class walked into the Avengers' Tower.

"Flash, shut the fuck up, at least Peter actually has an internship here." MJ scoffed, making Peter sigh and look up at the building that, unbeknownst to everyone but MJ and Ned, the boy was in at least a few times a week. Of course no one knew who he really was, and so he had to act in awe of the building, and had to act like he didn't know any of the staff that were passing him by the minute. But he knew that the hardest person by far to ignore would be Y/N. When Peter had first joined the team, Tony had made it clear to the boy that his daughter was off-limits. Needless to say that that hadn't lasted long. Peter had broken Tony's one rule and had started dating Y/N, though Tony had soon seen how happy the pair were, and so he had let it happen. Peter and Y/N had been dating for two years now, and she was truly the love of his life. She was amazing in every way possible, including how she was intelligent enough to fix all of their suits when even her dad couldn't. That took some serious brains.

"Now, we've been privileged enough to be granted access to the labs and private quarters, so please follow me up, and stay together as a group. Also, please be considerate of the fact that the private quarters are the homes of the Avengers, so we ask that you be respectful." The tour guide smiled as the class piled into the glass elevator. Peter bit his lip and pretended to be admiring the view like the rest of his classmates were. Soon enough, the elevator pinged and everyone flooded out, Peter following slightly behind so that everyone would go ahead of him. And thank fuck that he had. As Peter passed the door to one of the smaller labs, it flew open.

"Woah!" He gasped, his eyes widening as a familiar hand grabbed his shirt and pulled him into the lab. Within seconds, Y/N pressed her lips against his, Peter smiling and returning the kiss as he shut the door behind them.

"Baby, as much as I love this, you know that I can't be in here." He mumbled against the girl's lips, yet he made no attempt to stop the kiss as his hands gripped her waist, and her hands held his face as the pair stumbled back.

"It's only quick, Pete, I promise. I miss you, and I needed to kiss you." She smirked. He returned it and shook his head as he pushed on her hips and lifted her up to sit her down on the counter behind them, their lips still clashing as he stood in between her legs.

"God, you're so fucking irresistible, angel." He mumbled into the kiss. She smiled at his words, Peter's heart fluttering at simply everything that she did as they continued to make out. Their hands continued to feverishly pull at each other's bodies, Peter's tongue having dominated the kiss and started to roam his girlfriend's mouth as he slipped his hands underneath her top, and up her back so that they could be skin to skin. Y/N's fingers buried themselves into his curls and pulled gently, Peter quietly moaning into her mouth as their tongues and teeth continued to clash violently together in what must have been one of the most intense make-outs that they'd ever had.

"And in here, we have-oh my god!" Peter's eyes shot open, Y/N having the same reaction as Peter broke the kiss. He turned his head, his eyes widening even further and his heart virtually stopping in his chest at the sight that they were confronted with. Peter's entire class stood at the other door to the technology lab, all of them staring at the pair with wide eyes as MJ and Ned tried not to laugh.

"I, I, um, I...fuck." Peter gulped as he quickly pulled back from Y/N, the girl also jumping down from the surface and smoothing out her clothes as Peter couldn't help but just stare at his classmates in sheer terror.

"There's no way that you're actually dating Tony Stark's daughter. No fucking way, how do you even know her?!" Flash exclaimed. Peter gulped and looked at Y/N, his heart violently racing in anxiety as he tried to figure out how he'd get out of this. After all, he did have the excuse that he did the Stark Internship, but that was nowhere near enough to account for how he was so close to Y/N that he could make out with her.

"I-I, um...I-."

"He doesn't know me. I thought that he was cute, so I started flirting with him, and one thing led to another. Just because you don't get random girls coming up to you and showing an interest, doesn't mean that he doesn't." Y/N nodded as she lied. Peter's eyes widened, as did everyone else's as laughs and gasps filled the group as they looked at Flash.

"W-what, of course I get girls coming up to me! Fucking whatever." He scoffed, making everyone laugh as the boy stormed out of the class.

"Okay, everyone, we better get moving, let's move on." The tour guide smiled in a clear attempt to distract everyone from the situation as they started to be herded out. Once the room was empty again, Peter puffed out and let his eyes flutter shut as he turned back to Y/N.

"That was too close. But thank you so much, angel. I know that it can't have been easy for you to deny that you know me." He sighed as he curled his arms around her waist, and she rested her hands on his chest. She playfully rolled her eyes and shook her head.

"It's okay, Pete, I know that it's so important to you to keep your identity secret, and so it's so important to me too. Don't worry, you can make it up to me by taking me out tonight." She smiled teasingly.

"Sounds perfect, baby." He returned her smile before leaning down and pecking her lips.

"I need to go, but I love you, and I'll see you later." He nodded as he retracted his arms from her and opened the door to the lab again.

"Love you too, and see you later." She chuckled, making him smile as he left the room. He shook his head to himself, his heart fluttering with the thought of how he'd gotten someone so fucking perfect as he rushed back to the group, and rejoined the tour.
