Lightweight Killua AU
An AU for Lightweight Killua Headcanon
“You’re lying.” Gon stared at Killua dumbfounded, “There’s no way you’re telling the truth.”
“I told you a million times. I’m immune to poisons- that includes alcohol, dummy.” Killua said, still looking through the aisle of different shaped bottles of various alcohols. “Logically, that means I can drink as much as I want and won’t feel a thing.”
“Still, though. I don’t buy it.” Gon pouted and Killua rolled his eyes at him.
“Too bad. It’s the truth. I can drink whatever I want and not have to worry about getting drunk.” Killua smirked, “You, on the other hand, would probably fall over after one drink.”
“I would not! I could handle drinking. Mito-san just never let me…” Gon stated, huffing. “And if you’re such a heavyweight, prove it. I wanna see.”
“Of course she wouldn’t let you drink! We’re underage!” Killua said, his eyebrows raised, “And fine! I will! I’ll drink all night and watch you get drunk.”
“You’re the one getting drunk. It’s impossible to be immune to alcohol. You have to feel at least something.” Gon said, looking at all of the bottles before picking a couple- more out of looks than out of actual contents since he wasn’t exactly experienced with anything like this. Killua rolled his eyes before grabbing a few random bottles himself.
“Uh huh. Sure. I wonder what kind of drunk you’ll be. Hopefully not a loud one.” Killua winced, imagining an overly drunk Gon speaking ten decibels higher than normal.
“I bet you’ll be a funny drunk.” Gon said after some thought once they got to the checkout. The cashier eyed them suspiciously.
“Aren’t you kids a little young for drinking? Can I see some IDs?” He said sternly, looking from Killua to Gon.
“We’re sixteen!” Gon grinned, getting wacked on the back of the head by Killua.
“And we have these.” Killua handed the cashier his Hunter’s License as Gon pulled out his. The cashier sighed before bagging the drinks, waving them off.
“Go ahead.” He rubbed his temples, “Just… Don’t get into any trouble. I don’t need the Hunters Association giving me crap for giving kids alcohol.”
“Thanks!” Gon beamed, grabbing the bags.
“We’ll be fine, don’t worry!” Killua smirked and followed Gon out the door.
When they got back to their hotel room, the boys put out their spread of alcohol on the table. They’d ended up with tequila, vodka, wine, gin and whiskey. Gon stared as Killua got some paper cups from the counter before opening the bottles.
“Ew that smells disgusting.” Gon scrunched up his nose as the smell hit him. Killua rolled his eyes before picking up the bottle of gin and pouring a little in a cup.
“It’s supposed to. At least, that’s what I’ve heard. Don’t be such a baby, Gon.” Killua teased, handing his friend the cup and pouring himself one. Gon stared at the contents unsure and Killua struggled not to laugh. “Just drink it.”
“You haven’t had yours either!” Gon said, whining.
“Okay fine. On three?” Killua suggested and Gon nodded. “One… Two… Three!”
Both boys downed the cups of straight gin before their eyes widened. Gon spit hit out back into the cup, coughing. Killua clamped one hand over his mouth, the other clutching the counter as he struggled to swallow the liquid. When he succeeded, he gasped and coughed, his face red from the burning. He looked at Gon who’s eyes were watering.
“Th-That was horrible!” Gon said, before laughing, “Y-You should see your face, Killua! It’s so red!”
“Speak for yourself! You look like you’re crying your eyes are so watery!” Killua laughed. “Ugh, that tasted awful. Like antiseptic or something.”
“Yeah, my throat- Wait a minute. You’re having more?” Gon said, staring in shock as Killua eyed the bottle of vodka suspiciously before pouring some.
“I said I was gonna drink all night, didn’t I? I have a point to prove. You want some, lightweight?” Killua said, waving the bottle in front of Gon tauntingly. Gon narrowed his eyes and snatched it, pouring some into his cup- already partially filled with gin.
“Cheers?” Killua grinned, hitting Gon’s cup with his before they both forced it down.
“Heh, my face feels hot.” Killua blinked a few times, trying to make the room stop. Gon eyed him warily, looking suspiciously sober to Killua. “Hey, you haven’t drinked… drunk… drank… what’s the past tense?”
“Killua, maybe you should stop. You look pretty drunk.” Gon said, getting up from his bed to throw away his cup. Killua frowned stubbornly.
“No, you aren’t even drunk. And I am not drunk. And we have all this stuff to drink.” Killua slurred, stumbling a bit to the counter. Gon sighed, walking over to him, taking a bottle from his hands.
“It’s almost all gone anyway. And you are too drunk.” Gon said, crossing his arms. His cheeks were pink but for the most part, Gon had proven to be the one who could handle his liquor. “Come on, let’s go to bed. It’s getting late.” But Killua was already shaking his head, a dazed look in his blue eyes.
“‘m still thirsty.” He reached for the tequila before Gon swatted his hand away, a glare in his eyes.
“No, Killua. If you’re thirsty, I’ll get you water.” Gon said, his arms crossed, “I mean, sheesh, this stuff doesn’t even taste good. A stupid bet isn’t worth it. And you’re already drunk anyway- so you lost.”
“Say, Gon, you’re really hot.” Killua said seriously, staring intently at the teen in front of him. Gon flushed brightly in surprise.
“H-Huh?” Gon squeaked.
“You are. You were cute before. But now you’re really hot.” Killua tilted his head a bit, his eyes glossing over Gon’s body. “Really, really, hot.”
“Y-You’re drunk. You don’t mean that.” Gon laughed awkwardly, scratching the back of his head.
“I do, though. You’re really hot and really amazing.” Killua hugged Gon’s body before he could stop it.
“K-Killua, l-let go.” Gon blushed, trying to wiggle his way out of Killua’s hold but succeeded only in having Killua draped along his back, his arms around Gon’s neck.
“Why is something so bright friends with me?” Killua mumbled, nuzzling Gon’s neck, eliciting a squeak from him.
“Where’s all this coming from?” His voice rising an octave when Killua tightened his hold on him.
“I never said ‘nything ‘cause I love you.” Killua slurred, before hiccuping. Gon’s breath hitched, as Killua continued. “You’re just so happy, you know? And you’re friends with me. I followed you on your date with Palm that one time because I wanted you to ask me out. But you’re a stupid head and-”
“W-Wait, you love me?” Gon whispered, a permanent blush staining his cheeks. Killua glared, rubbing his cheek on the back of Gon’s neck.
“Yeah. You gotta pay ‘tention, dummy. I’ve loved you for forever. You’re really cute and-”
“It’s not nice to lie, Killua. Even if you are drunk.” Gon’s voice shook a bit, trying to process it. Killua growled in frustrated and stumbled off of Gon before grabbing his face in his hands.
“’m not drunk. And I’m not lying!” Gon barely had time for his eyes to widen in surprise before Killua yanked their lips together.
“Ugh, dammit…” Killua grumbled, feeling the contents of his stomach sloshing dangerously. He planted his face further into his pillow in an effort to block out any daylight. His head pounded, his stomach hurt more than it had in years, and he couldn’t remember a thing.
“Um, Killua?” Gon asked quietly, holding a glass of water some pain medications. “A-Are you feeling alright?” Killua stayed silent so he pressed further, “Killua?”
“I lost, okay? I got drunk. Big whoop.” Killua muttered, looking up to glare at Gon- only to find the boy looking away, a red blush across his cheeks. “Gon? What’s wrong?”
“N-Nothing. Um, here’s some medicine and some water.” Gon practically thrust the items at Killua without looking at him.
“Thanks…” Killua eyed Gon suspiciously as he took the medicine, cringing as his stomach lurched a bit. He set the glass down on the bedside table. “What…What happened last night? I don’t really remember much after we got into the vodka…” Killua’s cheeks turned pink, imagining what he could have said or done.
“You don’t remember anything?” Gon said, looking back at Killua surprised. Killua shook his head, gingerly sitting up.
“Nope. Nothing. I remember feeling kinda funny and I remember you asking me if I was okay. But I wanted to win and figured I could shake it off. Guess not.” Killua said sheepishly, still wondering why Gon was acting so weird. “So, what’d I do?”
“You, um…” Gon chewed his lip, “ran outside in your underwear. Sorry, I tried to stop you but you were kinda fast…” Killua sat there before his face turned from shy to mortified.
“Wh-What?! No way. There’s no way I did that.” Killua said, panicking. He looked up, catching a glimpse of guilt in Gon’s eyes. His own eyes narrowed, “You liar.”
“I didn’t lie!” Gon glared at the accusation- no matter how true it was, he was not a liar.
“Yes, you did! You have guilt written all over your face!” Killua ignored the urge to throw up and the way his head was screaming at him to lie back down.
“Ugh, fine! I lied! There, you happy?” Gon groaned, crossing his arms across his chest.
“I’d be happier if you would just tell me what happened!” Killua said, really panicking at this point. Why wouldn’t Gon look at him without getting all flustered.
“Okay, okay… You kinda, sorta, called me hot.” Gon flushed. Killua blinked before glaring at him.
“You’re lying again!”
“I am not! You said you loved me too!” Gon yelled his blush bright. He watched Killua’s cheeks turn pink. “If you don’t believe me, you said you followed me on my date with Palm because you were jealous and-”
“I was not! She was crazy and I didn’t trust you with her!” Killua’s eyes widened before he turned an even darker shade of red. Gon was in the same boat, torn between teasing his best friend, and pressing him for more of a confession- a sober one.
“S-So… do you?” Gon started, his voice quiet and hesitant.
“Do I what? Do I think you’re hot? Because the answer is no. You are not hot right now.” Killua huffed, getting up and walking towards the bathroom. Something in Gon’s eyes sparked, a grin reaching across his face.
“Right now? You mean I normally look hot? Or just sometimes?” Gon teased, following him. He could see Killua’s ears turn red as he stormed into the bathroom, slamming the door behind him.
“I am never drinking with you again!” Killua yelled from inside the bathroom and Gon couldn’t stop the laughter bubbling in from his chest.
