Requested by marvelfan211: Y/N is Tony's daughter and is in a secret relationship with Peter. One day, before a mission, Tony notices hickeys and scratch marks on Peter's back.

My eyes shot open, my heart racing and a loud gasp leaving my lips as I jolted up in bed and woke up from the horrific nightmare. I puffed out and held my hand to my chest, my heart racing so quickly that it hurt as I tried to come down from the terrifying thoughts that were part and parcel of who I was. And who I was, was Tony Stark's daughter. I wasn't to be mistaken, I loved my father and my makeshift family that was made up by the Avengers, but we had lost a lot, including Nat, who had acted as my mother figure for my whole life. One of the only people I had left was Peter, my boyfriend, but I couldn't even be completely open with that. Given that my dad was his boss, Peter was aware that I was strictly off-limits in any more than a friendship sense. But he hadn't listened, and I was grateful for that every day of our lives. We'd been secretly dating for six months now, and somehow had managed to keep it secret from the world's most intelligent and amazing people. But it was getting obvious to both of us that the walls were closing in, and it was only a matter of time before we were caught. But for now, I'd enjoy him as much as I could. I sighed and stood from my bed, my mind knowing that I wouldn't be able to get back to sleep now that I was so anxious. I opened my door quietly and tiptoed to Peter's door, my eyes looking around to check that no one would see as I opened my boyfriend's door and slipped into the room. Peter's eyes opened as I came in, his eyebrows furrowing as he saw me from his position lying down in his bed.

"Baby? What are you doing up, are you okay?" He grumbled tiredly as he leant up on his elbows and allowed his bed sheets to fall down to expose his naked chest.

"I had a nightmare, I can't sleep anymore." I responded equally as quietly. Peter's face softened, a sigh leaving his lips as he immediately pulled back his covers.

"Aw, babe, I'm sorry. Come here, it's okay." He nodded. I gave him a small smile and crawled into bed next to him, my head and hand landing on his chest and Peter's arm curling around my waist as he put the covers back over us.

"What was the nightmare, angel?" Peter cooed, his spare hand raising to gently stroke my cheek as he pressed kisses to my forehead.

"Same old. I don't want to talk about it." I mumbled and shook my head.

"Okay, baby, that's okay. We don't have to talk about anything." He promised. I gave him a small and thanking smile, making him return it as I leant up and gently kissed him. He returned it, both of our eyes fluttering shut as my hands raised to cup his cheeks. Peter's lips curled into a smirk, making me return it as my boyfriend deepened the kiss and gently pushed me down so that I was lying against his bed, and he was hovering over me. He slipped his tongue into my mouth, my hands raising to gently pull on his curls as we started to make out, our minds fogged with lust within seconds as Peter broke the kiss and moved his lips down to my neck.

Peter's P.O.V

Peter strolled relaxedly along the corridor to the missions' room, wind in his sails and his heart full of love after the amazing night that he'd ended up having with Y/N. After she had come into his room, they'd had incredible sex, and now Peter was more than ready for the mission that he was going on today with Tony. The doors slid open, making Tony look up at the boy as he strolled in casually.

"Morning, Pete, you okay?" Tony asked.

"I'm great, Mr Stark. Ready for today's mission." Peter smiled and nodded, making Tony chuckle and raise his eyebrow.

"Glad to hear it, kid. Start getting into your suit, we leave in ten minutes." He stated.

"Yes, boss." Peter smiled, making Tony chuckle and shake his head as Peter headed over to his cabinet. He pressed his thumb against the reader, the metal doors sliding open within seconds to reveal all of his equipment as he turned his back to his boss. He pulled his t-shirt over his head, the boy starting to get ready as he stood there shirtless.

"Peter, holy shit, what happened to you?!" He heard Tony scoff, making his eyebrows furrow as he looked over his shoulder slightly at his boss.

"What's that, Mr Stark?" He asked before turning back to his suit.

"Some chic has marked you up good, kid, shit." Peter's eyes widened, his body going numb in a second as he realised what his boss was seeing. Unbeknownst to Tony, he was looking at the scratches and hickeys that his daughter had left on Peter's back. And the boy's mind was working overtime to try and figure out a lie to cover this up with.

"O-oh, f-fuck, shit, I, um, I didn't realise, fuck-."

"Relax, Pete, it's only natural. So, who's the lucky girl?" Tony teased with a smirk. Peter gulped and stared at him with wide eyes, his heart pounding more harshly by the second as he tried to think of a lie, any lie at all at this point.

"I, she-she, I-she goes to another school." Peter blurted out. Tony's eyebrows furrowed, his smile dipping as he clearly figured out what was going on. Not that Peter was surprised, Tony was the smartest man on the planet and Peter was bumbling like a fucking idiot, so of course it didn't take a rocket scientist to put two and two together.

"Peter...who the fuck did that to your back?" Tony asked again, though all of the jest and teasing had left his voice as he stared right at Peter.

"Dad, can I-oh, shit." Peter's eyes widened, his heart jumping again as Y/N appeared at the door. She also stared at the pair with wide eyes, everything unravelling in front of them as the three of them stood in a triangle with gazes locked.

"Shit." Peter gulped.

Y/N's P.O.V

I headed along to the missions' room of the Tower, my mind knowing that both my dad and Peter would be in there preparing for their mission that they were due to go on.

"Dad, can I-." I looked up as I got into the room, my eyes widening at the sight of Peter shirtless, and the scratches and hickeys that I'd made clearly on display as my dad stared at them.

"Oh, shit." I gulped. Peter's eyes widened, my boyfriend looking at me as both him and my dad saw me. I also stared at the pair with wide eyes, everything unravelling in front of us as the three of us stood in a triangle with gazes locked.

"Shit." Peter gulped.

"One of you better start talking, now." Dad spat as he looked between us.

"Dad, please-."

"Y/N, we'll probably be gone for about an hour on this mission. You have until we get back to explain this. And you better hope to god that I don't let Peter die on this mission." Dad nodded, making Peter's eyes widen further as my dad firmly grabbed his shoulder.

"Mr Stark-Y/N, help." Peter gulped, making me return it and watch helplessly as my dad dragged Peter out of the room, and towards the jetti for their mission.

I sat in the living room of the Tower, my fingers anxiously tapping an unknown tune against my legs as I waited for Peter and my dad to get back from the mission. The mission that they'd still gone on literal seconds after he had discovered that Peter and I weren't just friends. As if on cue, I looked up to see the jetti landing on the heli-pad. I took a deep breath and stood up as dad and Peter walked out, Peter still looking terrified as they headed into the room.

"Dad, I know that this looks bad, but please hear me out-."

"There's no need. Peter told me everything that I needed to know." Dad nodded as he looked at my boyfriend. My eyebrows furrowed, making Peter give me a sheepish and nervous smile as he looked at me timidly.

"What did you say, Pete?" I asked quietly.

"He told me about how much he loves you. About how he fell for you the second that he saw you. He told me about how he'll always do anything for you, that he'll always protect you, because you're his world. He also promised never to let me see the...handiwork...that you left on him again, as long as I accepted the relationship. Basically, honey, he said a whole lot of sweet shit. And I know that I can be an asshole, but I'm not heartless." Dad chuckled and shook his head. My face softened as I looked at Peter, him giving me a small and still timid smile as my dad revealed what he'd said to him. Every word warmed my heart, every sound only made me fall more for Peter than I already had.

"Aw, Peter." I choked as I wrapped my arms around his neck in a hug. Peter returned it without hesitation, his face burying into my hair as he hugged me back.

"I'm not going to stand in the way of you two, especially as it's clear that you make each other very happy. But I can't be more serious about never wanting to see again what I saw this morning, okay?" Dad reiterated, making me wince as I pulled away to look at him, Peter's hands still on my waist as we turned to face him.

"Understood, dad, I'm sorry." I smiled sheepishly.

"Alright, kid. Have fun, you two, but not too much fun, and always SAFE fun, I'm too young to be a grandfather." He teased, making me chuckle and Peter blush a deep red as dad walked away, and left us alone once more. I puffed out and looked at my boyfriend, his eyes wide as he returned the gaze.

"Well...that went significantly better than I thought that it would." He chuckled and shook his head.

"Apart from you allowing my father to see what I did to you." I teased.

"Hey, you're the one who did it!" He retorted with a laugh.

"Okay, true, fair." I smiled, making him laugh again as he leant in and gently kissed me.
