You knew your brother wasn't going to be happy when he found out. You knew Peter would probably huff and puff and wish he could actually blow the house (or apartment building, in this case) down. He would probably glare at you and Wade in silence before getting up and going to his room to fume and sulk.
You expected this, all of this because that was the type of person Peter was; no matter how angry he was, he would never hurt you or Aunt May in his anger. He loved you both too much.
Deadpool, however...
Crash!
"Wilson, I'm gonna kill you!" shouted the angered voice of your younger brother, and not a second later the figures of the anti-hero and the superhero came rushing into the living room.
You sighed as you wished - for the hundredth time - that you had agreed to Aunt May's decision. She knew Peter as well as you did, and she knew if Peter found out about the relationship with Deadpool in the room, there was probably going to be violence. But you just had to go and deny it all, going through with your original plan anyway - and at the same time Peter had just come home from one of his checks around the city.
You couldn't have picked worse timing, could you? God, you really hated it when Aunt May was the sensible one sometimes.
"Aww, Spidey, you wouldn't do that to your good ol' pal, Dead-!" Wade replied, playfully, only to pause when Peter growled. He yelped in surprise as the younger male lunged for him.
Wade stepped swiftly aside, giving Peter no time to stop stop himself. You watched in distant horror as he smashed gracelessly into the vase - the very vase that just so happened to be Aunt May's favourite too. A well-placed web was the only thing that saved the two of you from Aunt May's wrath.
You took a deep breathe, calming your thundering heart. Both of you knew a well-trained assassin was nothing compared to an angry Aunt May, and neither of you wanted to suffer that.
Peter carefully placed the vase onto the sofa before resuming his shouting-fighting-whatever match with Wade. Deep down, you still wished she'd appeared. She'd have an actual chance of stopping all of this. Even Wade was scared of annoying her.
Alas, she was not. She was upstairs, sorting out boxes of things she wanted to take down to the charity store, and very promptly ignoring the mess you were making down here. So it was down to you to stop them.
Stepping in between the two of them, you crossed your arms and began, "Peter-," only to be interrupted by said man turning to you.
Removing the mask, he glared at you, though not as fiercely as you'd expected, and raised a hand.
"Don't, (Y/N). I don't want you to date him! He isn't good enough for you!" You huffed and uncrossed your arms to stop closer to him, eyes narrowed and finger pointing accusingly at him.
"No, Peter! You don't get to decide who is and isn't good enough for me!" You shouted, "Remember, I'm older than you. I've gone through my fair share of heartbreaks but this one, Wade..." You looked over your shoulder, looking up at the masked face of your boyfriend with loving eyes. "-Wade is different. I love him," You turned back to your brother with a glare, "-and no matter how much you dislike him, that isn't going to change. I won't end this just because you disapprove of it!"
Peter stared with only a smidgen of surprise. He knew you just as you knew him, which meant he knew very well once you had your mind set on something, you were going to get it, and you wanted Wade Wilson. You really wanted the rude, perverted slimeball....
Peter sighed and looked away, rubbing a hand over his face as he clenched the other around his mask. He wanted what was best for you and he knew it wasn't Wade Wilson, but if he made you happy - though how, Peter did wonder -, then maybe... no, Wade- Deadpool can't be the one to make you happy!
He groaned and crossed his arms, shaking his head like the stubborn teenager he was. You glared and re-crossed your own.
If Deadpool hadn't known you were older, he'd have mistaken the two of you for twins. You were perfectly in sync with each other; you two could have a whole conversation merely by your eyes, and to top it off, you both always finished each other's sentences (and once sandwiches, but that didn't end well... it still gave Wade the shivers remembering it.)
Though he'd never admit it, Wade found this incredibly creepy - and sexy, but he'd never admit that too.
Finally Peter relented and you smirked, the silent conversation between the two of you settling the whole thing. Just like that, it was over.
Peter quietly sighed, unfolded his arms to open wider and waited for you to take the offer. You chuckled and walked into the hug, wrapping your arms around his neck.
"Just, be careful, please." He whispered into your ear and you nodded to reassure your protective little brother. You knew he was just trying to look out for you, and it was nice to know that someone was looking out for your back. However, it was also nice to know he was going to let it go.
Pulling back, you pecked him on the cheek and smiled at him, happy when you got a smile back.
"Why don't you go back to Aunt May? She needs help with packing up the clothes anyway." You asked, and although Peter looked hesitant, he eventually walked off, glaring at Wade as he walked past. The little nudge was to be expected, however, but thankfully Wade just let it be, stumbling a little back for good effect.
Once Peter was out of the room and the door was closed, you sighed and walked closer to Wade, who instantly wrapped his arms around your waist, bringing you in closer as he bent down to kiss you on the forehead.
"Your brother hates me." Wade, as per usual, sated the obvious, and you rolled your eyes, laying your head on his chest as you wrapped your arms around his neck.
"He doesn't hate you, per say; he just- very strongly dislikes you."
Wade chuckled and kissed you again, this time on the lips. The kiss was sweet and lasted a couple of seconds but god, did you crave more. He pulled back, leaning his forehead against yours, and you closed your eyes as he did so.
"I love you," You whispered.
"And I you." He replied.
You smiled, happy you were with Wade and that your brother was going to let your relationship with Wade Wilson go...for now.
