Work Text:

"Adrian," You looked up at him from the driver's seat with a frown. "You gonna tell me what happened?" 

 

He met your eyes for only a moment, weighing the options in his mind.

 

Lying to you made him feel bad, seeing you trust him wholly and take his word as truth when he knew it wasn't. And you always did, whether out of love for Adrian or that naïve way you wanted to trust almost everyone. The latter was one of the things he always loved about you.

 

But then again, if he told you what he'd been up to, he'd have to tell you about the butterflies, and you'd be in even more danger than you were now. 

 

He sighed, then breathed in. "No."

 

"What?" You huffed, crossing your arms. "I was worried sick about you, you know, and then I went through so much trouble to get here, and now you won't even tell me why you were arrested?" 

 

Your brother turned to face you, his gaze particularly sympathetic in a way you were determined to not be receptive to purely out of spite.

 

"Baby," He started. 

 

You cringed. "Oh my god, don't call me that, I hate it when you do, and you're always treating me like one! What, you think I can't handle the truth?"

 

Adrian shook his head. "It isn't that." 

 

You groaned out of frustration, uncrossing your arms only to fidget with your seatbelt. "What is it, then?"

 

He hummed, shifting in his seat. He hated it when you were upset with him. Fortunately, he usually knew how to alleviate it. And he supposed the least he could do was tell the truth about why he couldn't tell the truth. "I don't want anyone to hurt you."

 

Adrian saw your face soften at his words, his sigh out of relief this time. "Adriann," You smiled, bringing up your hands to hide the blush you already knew was building on your cheeks. "I... That's really sweet. I'm sorry for being so upset, I didn't know..." He then grabbed your hand, pressing kisses to each of your fingers. 

 

"I know, I know," He mumbled, lips pressed against your palm now. "It's fine. I'm sorry for not saying anything sooner, you deserved to know."

 

You were looking away from him now, all shy just the way he liked you. He opened his mouth to speak again, first studying your expression. You were in a good mood, he saw. Happy to be reunited with him.

 

He squeezed your hand two times, then when you looked at him, whispered, "You gonna let me make it up to you?"

 

Adrian heard you gasp. It was a genuinely flustered noise, but he knew you'd say yes eventually. You always did.

 

So when you nodded finally, he wasted no time getting you both in the backseat, throwing your legs on either side of his waist. 

 

"Wait, wait." You stopped him with a hand on his shoulder. "It's light outside. Someone could see." 

 

Your brother sat back up, glancing out the windows. There were definitely tons of people still outside, but these were the types of lies that didn't make him feel that bad.

 

"There's no one out." Muttered Adrian with an easy nonchalance.

 

"Really?" Your eyes widened as you pulled him back down, eager to resume. 

 

No. "Yeah," He smiled against your lips when he kissed you, reaching down to slide your panties halfway down your legs. He pulled back from the kiss once he did, and rested his head in the crook of your neck. He then pulled them all the way down.

 

You kept your eyes closed until you felt Adrian trying to push his way in past the resistance as you hadn't seen him for a while. "Mmm..." You whined, squirming a bit. "Hurts, Adri,"

 

Adrian kissed right above your collarbone, a chaste apology. You felt his thumb swipe side to side across your clit again and again, collecting the wetness there.

 

"Ah, um, and..." You gasped, rolling your hips into the touch. "I think I need you to finger me."

 

Adrian chuckled, his gaze now focused between your legs. "You're just saying that 'cause you want me to." Still he obliged, teasing in his index finger first.

 

"Maybe." You closed your eyes again, concentrating on that familiar feeling of warmth Adrian's touches always gave you. 

 

Once his first finger fit inside you up to the knuckle, he slipped his middle finger in. 

 

"Mm, ah, ow..." Your moans, he noticed, while frequent, were always quiet as a mouse. He shushed you with his mouth, kisses light and gentle as he worked on stretching you out. "Shh... Just one more, one more for me." You whined at this, attempting to kiss him weakly.

 

"Hush, baby, I gotta get you ready, don't I?" Your slick was now dripping between his fingers, down his hand and nearly all the way to his wrist but he proceeded with a third finger despite your vocal displeasure. "You wanted this..."

 

You whined again, pouting. It was true, you had been desperate for it, but you just felt so full now, so ready and overwhelmed, yet your older brother insisted on stretching you further. You couldn't deny how good it felt, either. There was no use, knowing his knack for observing your body's reactions. He had picked up on how, even through your complaints, you sought out his touch.

 

Adrian rubbed the heel of his hand, slick with your wetness, against your clit, trying to offer you some pleasure so you wouldn't whimper about him being a tease once you finished. This seemed to satisfy you, your moans now sounding higher pitched and more content. He then took his fingers out of you completely to give your clit some more attention.

 

You grabbed hold of his wrist, intending to keep him there. "Adrian, Adrian..." You gasped out among various incoherent babbles. He felt your fingernails dig into the side of his arm, sharp enough to draw blood, but he didn't mind, This was what older brothers were for anyway. Attending to their younger sisters. 

 

"Adrian, oh..." You bit your lip, thighs closing around his hand. "I'm so close." He let you keep on like that for a few seconds before his hand came to a stop, then pulled away when you gripped his arm tighter. 

 

"Wh... What are you doing?" You blinked, tears of pleasure running down the sides of your face.

 

Adrian wiped them all away with his free hand, licking juices off his other one. "Come on, you know I wanna feel you cum when I'm in you." He said in between loud, obnoxious slurps.

 

That was right, you had forgotten. "Oh." Adrian did always love feeling you come undone around him, even more when you finished together, he was trying to achieve that. You blinked, looking up at him. What kind of sister would you be if you denied your older brother something he delighted in that much?

 

Your legs wrapped around Adrian's waist once he settled in you and you began talking, your hands already planted firmly in his hair. "I love you, Adrian, I feel like I should say it more."

 

Adrian smiled at this, his cheeks flushing. You were always so nice to him, a breath of fresh air seeing as he usually didn't get that from anyone else. "I love you, too... And you say it all the time, you text me 'I love you', like, every day." 

 

Your eyes closed once again, Adrian's slow pace nearly lulling you. "Yeah, but I always mean it in like, a sibling way which, well we are siblings but..." You paused, letting out a soft moan. "I love you in the other way, too."

 

"Other way?" Adrian questioned as he tilted his head like a puppy.

 

"Mmm... Like, in the boyfriend and girlfriend way..." You tugged a few strands of his hair, just to get him going a bit faster. 

 

"Wow..." He took the hint and picked up the pace. His thrusts were fast yet stayed shallow, as if trying to keep himself from cumming too early. "You want me to be your boyfriend?"

 

You made Adrian look directly down at you, pulled his face closer to yours. "Adrian,"

 

"Yeah?" He stopped to admire you. 

 

"Are you, like, joking?"

 

"...About what?"

 

"Adrian, I haven't just been letting you have sex with me for no reason."

 

Adrian blinked, looking side to side cluelessly. "I just thought we were in some sort of... Siblings with benefits type of thing."

 

"Adrian."

 

"What? I just- I figured you really needed to get off and didn't trust anybody else. Guys are... disgusting, you're safer doing it with me anyway."

 

You groaned, smoothing your hands over your face. "I like, literally let you cum in me last time."

 

"I thought that was just 'cause you were in a good mood that day." Adrian scoffed, giggling softly. "You actually like me like that?"

 

You nodded, feeling Adrian's cock twitch inside you at the thought. This made you tighten around him, causing him to go faster.

 

"Shit," He exclaimed. "You are actually the best little sister a guy could ever ask for." He reached down, thumb swiping up your clit.

 

"Don't say that while we're-" 

 

"No, but it's true, like," Adrian chuckled, capturing your lips in a much hungrier kiss than before. "You're the best."

 

As your breathing got heavy, so did his. "And I know you hate it 'cause you wanna be grown up now, but you are my baby. My sweet baby sister."

 

"Oh god..." Adrian groaned, his eyes shutting. "I won't last for very long."

 

"M- me neither..." You moaned, keeping your legs around his waist to hold him there.

 

Your eyelashes fluttered, glancing up at Adrian. He was so pretty when he came, you literally couldn't bear the thought of missing it. "You can cum inside again, if... if you want."

 

He did so eagerly, buried deep inside you with a whimper. He pulled back after a while, still rubbing your clit to get you off while he watched you convulse around him. "Oh fuck," His fingers worked against your clit diligently. It was almost as if he could cum again, watching you. 

 

Adrian mumbled your name when it was all over, with him sitting up and throwing your legs over his lap so you'd be more comfortable. 

 

"You meant what you said?" He asked, tracing shapes over your skin with his fingers. "We're dating?"

 

You sat up, balancing on your elbows. "We've been dating. I just don't think we can do couple stuff just yet." 

 

Adrian frowned.

 

"'Cause everyone knows we're siblings and all..." You added, your face twisting into a similar frown. "Sucks."

 

If Adrian were a cartoon character, he definitely would have had a lightbulb above his head right now.

 

"Not everyone though!" You made a confused sound, so he elaborated, "My friends, none of them even know you exist, I think."

 

"Oh, wow." You supposed it made sense. Being four and a half years younger than him, of course his friends, who you assumed were likely around his age, hadn't heard of you.

 

Then, it clicked. 

 

"You want me to meet your friends, Adrian?" Your eyes twinkled. He nodded, pulling you up onto his lap for a series of kisses across your face. 

 

"Guess we're a real couple after all, huh?"

 

Your brother hummed in agreement, helping you adjust your clothes back into place as he told you all about his friend group.


Later on, after having taken a shower at home (separate from Adrian's, unfortunately), Adrian took you to meet everyone.

 

The blonde one, Harcourt, you remembered, was the first to look at you curiously.

 

Economos didn't even look up when you came in, although you swore you heard him mumble a small 'Hi.' under his breath or something.

 

Adebayo and Peacemaker walked up to you, both of them nearly speaking over each other. 

 

"Who are you?" Peacemaker spoke first, squinting to see if he could place you.

 

Adebayo did the same, making you giggle at the two of them. 

 

Your brother had his hand on your shoulder, suddenly much closer than you remember him being just a few moments before. 

 

"Guys, I'd like to officially introduce my girlfri-"

 

"Sister!" You beamed, stopping yourself too late.

 

Adebayo blinked. "Um?" Her and Peacemaker shared a look, their expressions once again identical. 

 

You just stood there with your jaw dropped, searching your brain for any possible out. 

 

"She just meant that..." Adrian started, fingers tapping your shoulder. "Uh, we've gotten so close at this point that she might as well be my sister, right? Ha..."

 

You forced a laugh, your cheeks burning once you realized that now, everyone in the room was staring at you. Even Economos. You hoped to god that this wouldn't be their first impression of you. Adrian's freak of a sister-girlfriend.

 

Adrian gulped. Harcourt's eyes bored into his soul, and he took his hand off you quickly. "Oookay, that's all! My girlfriend's gotta head home now."

 

Looking around blankly, you finally said, "Yeah, bye everybody!"

 

Maybe if you were lucky they'd forget all about this?

 

"Bye Peacemaker, Bye Harcourt, Bye Adebayo, Bye Economos!" You waved awkwardly before leaving, wiggling your fingers then immediately making a quick exit.

 

"Shit," Said Adrian under his breath once you left. Peacemaker gave him a look, gesturing for Adrian to follow him to the side of the room. 

 

Once he did, Peacemaker looked around to verify everyone had gone back to doing what they were before you came in.

 

"Adrian, what the hell?" He whisper-yelled, his tone fairly accusatory.

 

Adrian shrugged, trying to seem nonchalant even though he was clearly sweating. "What, dude?"

 

Peacemaker leaned in closer. "That was definitely your sister." 

 

Adrian shook his head. "What?" He scoffed, hooking his finger under the collar of his shirt and pulling it thrice. "Don't be ridiculous."

 

"She looked exactly like you! And you two were side by side, I saw what I saw."

 

"Um..." Adrian bit his lip nervously. There was no way out of this one. "Well, like, so what?"

 

Peacemaker shook his head incredulously. "What, dude? What do you mean, 'so what?'?"

 

Adrian stuttered, trying to come up with something before giving up. "I don't fucking know, you tell me!"

 

Peacemaker's brows furrowed. "Huh?"

 

"Just- Just don't say anything to the others, okay?" Adrian was practically pleading.

 

"How the hell am I supposed to keep that promise? You expect me to just, not say anything about you humping your sister?" 

 

"Oh, don't even start with that shit," Adrian chuckled. "I am keeping so, so many of your dirty secrets!"

 

Peacemaker went quiet at that, retreating slightly. 

 

"And that's super gross by the way!" Adrian added. "I'm not into hook ups like you, it's..."

 

He paused. 

 

"I'm in love." He put his hands on his sides and puffed out his chest, seeking to look less like a petrified wet dog. 

 

Peacemaker put his hands up, sighing. "I can't handle this today. You win, I guess I can't say anything. Do me a favor though?"

 

"What kind of favor?"

 

"Keep that shit away from me."

 

Adrian scoffed, slightly offended if only on behalf his little sister's honor. "I wasn't planning on keeping it anywhere near you!"

 

"I'm not trying to be a fucking accomplice to your weird, incestuous love life." Peacemaker said before turning away and starting to walk off.

 

"You have committed multiple crimes, Peacemaker!" Adrian shouted after him.

 

'And it isn't incest if we love each other' he thought, but kept himself from saying.
