Spiderman's Sister (Tony Stark x fem!Parker reader)

(obviously some brother!Peter Parker as well!)

"Tony," you giggled, "Stop it." Tony had been praising you all night and it was really starting to be too much. "Why? You're the most beautiful woman here and I've got you on my arm. So why should I stop bragging about you?" You rolled your eyes playfully. It had been this way since you and Tony started dating. He lavished you with compliments and gifts even when you told him you didn't need any of that.

You hadn't been together long, but you knew that you loved Tony and you hoped he loved you. There was only one little thing. Your relationship was a secret from those closest to you, especially your brother Peter. Tony was Peter's boss and you couldn't imagine how awkward it would be if he knew you were seeing Tony. You'd find out though.

Tony had pulled you away from the party and into the kitchen where he could kiss you properly. Neither of you expected Peter to waltz into the kitchen. "Hey Mr. Stark I- Whoa! Sorry!" You pulled away from Tony, your face feeling like it was going to catch fire. Peter's jaw dropped. "Y/N? You and Mr. Stark?" You nodded and hid your face in Tony's chest. Tony laughed softly before kissing the top of your head.

"I...this is insane. You can't date him, Y/N! He's old enough to be our dad! And I work for him!" Peter burst out after a few moments of silence. You glared at him. You hated when people tried to tell you what to do. Tony huffed, clearly offended at the age comment.

"No, Peter. He's old enough to be your dad. Not mine. Besides, little brother," you bit back, emphasizing the word 'little', "I can date whoever I want. Now go home before I call Aunt May and tell her you snuck out again." Peter opened his mouth to argue, but thought better of it and left. You turned to face Tony who was frowning. "What?" you asked. "I'm not old." You giggled and shook your head. "No you're not. Now kiss me." Tony's frown turned into a smirk.

For days after that, Peter refused to talk to you both. After nearly a week, you'd had enough. You stormed into Peter's room, determined to talk to him. The door swung open and you stopped short. Peter stood there, frozen. His eyes were wide with fear. Your eyes scanned his form, taking in exactly what you were seeing.

"Y-You're Spiderman?" you finally managed to ask. Peter nodded sheepishly. He knew better than to try and lie to you. You'd see through him in a second. "Does Aunt May know?" He shook his head. He was waiting to see what you were going to do. You closed the door then you came over and gave him a whack to the back of the head. "Don't you ever keep secrets like this from me again!"

"Ouch! What about you? Keeping it a secret that you were dating Mr. Stark?" Your eyes narrowed. "That's not as dangerous as being an Avenger, Peter. Tony is a good guy!" Peter frowned and replied, "Yeah, but come on! Mr. Stark is my boss. My mentor. Now every time I look at him, I think about him becoming my brother-in-law." You arched a brow. "Whoa, slow down. I don't think Tony and I are that serious yet."

"He does," Peter blurted. His mouth snapped shut and his face turned red. "What?" you asked. "He does. I may have heard him talking about buying a ring soon." You rolled your eyes. "Were you eavesdropping again?" Peter shrugged. "Not intentionally. But Mr. Stark was talking to Dr. Banner about how you were the best woman for him and that he was going shopping for a ring. Face it, Y/N. He wants you to be Mrs. Stark."

"Oh my god." You both whipped your heads around to see Aunt May standing in the doorway. You had been so engrossed in your conversation, you didn't hear the door open and Aunt May enter. Her eyes bounced between you and Peter as if she couldn't decide who to confront first.

"Aunt May-" you both started but she raised a hand to cut you both off. "I don't want to hear it. You've both been lying to me. I'm just trying to decide whose lies were worse." For some reason, when you and Peter were both on the chopping block, you reverted back to a child. You immediately pointed to Peter. "He's the one doing something dangerous! I'm just dating a guy for goodness sake!" Peter glared at you.

"Gee thanks, sis." You laughed nervously and kissed his cheek. "Love you. Gotta go, bye!" You started toward the door. "Hold it right there." You froze. Something about Aunt May's tone told you it would be best to listen. You hated yourself for it. You were a grown woman!

"You sit down right now. The both of you are going to come clean. No more b.s." You started to argue, but Aunt May was having none of it. "Sit!" Like a dog, you both sat on Peter's bed. You placed your hands in your lap and exchanged a glance with Peter before looking up at Aunt May.

For a few moments, there was absolute silence in the room. Then, your phone went off. It was Tony. "Tell him I want him here now," Aunt May said. She wasn't playing and her look dared you to argue. You knew Aunt May wouldn't really do anything, but you could see how angry and hurt she was.

Tony arrived in record time. "Anybody home?" his voice drifted from the living room. "Back here." Tony appeared after a minute and smiled at you. "Why do you look like a kid who was called to the principal's office?" Aunt May pointed to the bed. "Sit down." Tony looked at her in confusion. "Now." Like you, Tony instantly sat down next to you. Aunt May left the room. Tony whispered, "What did I do?"

"I don't think we're supposed to talk," Peter replied. "Aunt May is pissed. She just found out about us. All of us." Tony nodded in understanding before Aunt May came back into the room. She glared at Tony. "Are you going to protect my kids?" Tony's brows furrowed, but he nodded anyway. He'd never let anything happen to you or Peter if he could help it. "I mean it. If anything happens to either of them on your watch, I will come after you personally and no one will be able to save you. Got it?"

"Got it." Aunt May nodded smugly then looked at you and Peter. You had never felt more awkward in her presence than you did right then. "If the two of you ever keep big secrets like this from me again, no one is going to be able to save you. Got it?" You both nodded vigorously. "Good. Now, what's this I hear about a marriage proposal?"

Tony glared at Peter. "You blabbed, kid?" Before Peter could answer, Aunt May moved her hand from behind her back and plopped something down on your lap. Bridal magazines. "We have a wedding to plan." She left the room, ignoring your and Tony's cries of "I haven't asked yet!" and "I didn't say yes!"
