Izuku's frat was throwing tonight and Katsuki never goes to parties, except tonight. Kirishima had dragged him there, not only that but he made everyone pregame beforehand too. So now Katsuki, six shots of tequila down, was stumbling across the yard absolutely crushing Denki and Jirou at beer pong.
"Hey Bakubro, you know you don't have to drink the beer if you win, right?" Kirishima repeats for like the fourth round in this game as Katsuki downs the liquid in the last of his cups. Of course he knows how beer pong works, but he's too drunk and the alcohol goes down his throat like water; the feeling is euphoric. He feels all warm inside despite it being a cool spring night.
"Shut up shitty hair I can do whatever I want," he turns towards him but almost loses his balance, grabbing onto the table to steady himself. Kirishima attempts to grab him but Katsuki is already out of reach as he starts stumbling back into the house.
"Where are you going dude I wanna play another round," Denki calls out after him. Kirishima says something along the lines of asking him where he's going, that Katsuki barely hears.
"I HAVE TO PISS," he yells at them, disappearing into the frat house.

Izuku and Shoto were standing in the corner of the kitchen, vibing to the music. Izuku was sipping on his second beer of the night, his other hand in the pocket of his jeans.
"DEKU," a fierce yell echoed a few distance away from him. The beer can stilled at his lips as he saw Katsuki stumbling in his general direction. "GET OUT OF MY WAY!"
"Kacchan? um," Izuku started, slouching against the wall. "I'm not in your way so what does that even mean?" he said sheepishly.
"SHUT UP DEKU," Katsuki yelled at him as he got closer.
Izuku scratched the back of his neck with his freehand, a puzzled expression on his face. Kirishima then popped into the kitchen, giving some compliment to Izuku and Shoto about the party while dapping them both up. He then turned to Katsuki.
"Yo Bakubro, you coming back outside for another round?"
"Oooh what are you guys playing," Izuku interjected, attempting to ignore Katsuki's glaring presence right in front of him.
"Beer pong! You and Todoroki should join," Kirishima responded enthusiastically.
Izuku stifled a laugh and turned to face Katsuki, who was staring at him with an angry scowl. "Beer pong? You know you're bad at that game Katsuki," he teased.
Katsuki looked like his eyes were about to pop out of his skull, "WHAT THE HELL ARE YOU SAYING I WIN EVERY TIME!"
"Nah you're definitely bad at that shit," Izuku continued to tease, irritating him on purpose. He stood a little straighter, sizing up to Katsuki's height.
Katsuki growled at him, "SHUT THE FUCK UP DEKU!" He got closer to him, Izuku could smell the alcohol in his breath. Katsuki wasn't that much taller than him, but with how close he was it felt like he was towering over him. "I fucking hate you," he said, barely audible to anyone else but him.
Izuku snickered in Katsuki's face, "it's okay I hate you too 'cause your bad at beer pong"
Katsuki's hand found Izuku's throat, his breath hitched as Katsuki gripped him tight. He felt Katsuki's nails dig into his flesh. "I'm the fucking best at it and your the worst," he said through gritted teeth.
The stupid smirk on Izuku's face didn't falter as he turned his face slightly away from Katsuki to take one last swig of his beer before tossing the can on the floor. He looked Katsuki in the eye and doubled down "No Katsuki, I'm definitely better."
"Oh yeah?" Katsuki's said, his grip tightening slightly around his throat as he pushed him. Izuku's back was flush against the wall as Katsuki was getting all up in his face. "Am I loser Deku?"
"Mhm," Izuku responded, he bit his lip slightly and looked Katsuki up and down. The lenses on his glasses glinting under the low light.
"Shut the fuck up," Katsuki muttered before his lips crashed into Izuku's, his fingers clenched around his neck as his tongue wrestled through his lips.
Izuku made a noise before opening his mouth ever so slightly as he kissed him back. The taste of beer and tequila coated Katsuki's mouth. Izuku's one hand found Katsuki's blonde hair, he tugged on his locks slightly, tilting his face to one side so Izuku's other hand found Katsuki's jaw. Katsuki groaned against his mouth, his grip on Izuku's throat loosening slightly. His other hand was clawing at Izuku's back, causing him to arch slightly against the wall.
Shoto was dumbfounded and Kirishima had pulled out his phone, ecstatically recording them.
Katsuki was kissing Izuku like a starved animal, biting at his lower lip and breathing heavily. His black frames grazing and poking Izuku's skin. Some people were walking in and out of the kitchen, paying no mind to them. Katsuki kissed Izuku's jaw and then his neck, biting his ear and mumbling shit angrily that Izuku couldn't hear over the music and the blood rushing up to his head.
Katsuki suddenly separated himself from Izuku, both of them panting. Katsuki grabbed Izuku's arm with one hand and Kirishima's arm with the other and dragged them back towards the door leading to the yard "We're fucking playing beer pong."

"Woah Bakubro I don't think you need anymore drinks," Kirishima said as Katsuki was throwing back the small cup in which Denki's ball had landed.
"S'how the game goes," he slurred.
It was Izuku's turn, Katsuki stood behind Izuku, his lips on Izuku's neck. His hands were caressing Izuku's waist.
"You're distracting me," Izuku said, trying to focus on aiming the ball.
Katsuki nibbled on his ear and looked across the table with narrow eyes, "mmnuh uh"
Denki was sick of this shit. He ended up winning the round, but at what cost?
—
Izuku was straddling Katsuki on the couch, they're lips reunited once again. The living room had cleared out a bit as everyone was doing their own thing. Some pop song was reverberating through the walls, drowning out their moans and groans.
Somehow they ended up on the floor. Then Izuku peeled himself off of Katsuki to take more shots in the kitchen, before Katsuki pounced on him again.
—
Eventually they ended up in the backseat of Izuku's car, parked in the driveway of the house. There were some party goers bumming cigarettes on the front porch. Izuku was taking a drag of his own cigarette with the window rolled down. He could still hear the music faintly coming from the house. Izuku's lips felt sore and his body ached. Katsuki was laying in Izuku's lap, eyes closed, the position unforgiving on his back in the cramped car. Izuku ran his fingers through Katsuki's hair, his skin glistening with sweat in the moonlight.
"Kacchan, how much have you had to drink tonight?" Izuku asked him, bring the cigarette to his lips again. He shivered slightly as a cool breeze crept into the car.
Katsuki stirred, "mmmdon't fuckinknow" he mumbled. He swayed as he sat up to look at Izuku. He had pocketed his glasses at this point, his red eyes staring daggers into him. "Shut up Deku," he said, pressing a finger to Izuku's lips.
"That's not my name, Kaachan," Izuku muttered against his finger.
"Izuku," Katsuki said softly, an unusual tone coming from him. He removed his finger and grabbed Izuku's wrist, taking a drag of the cigarette, all without taking his eyes off him, as if Izuku would vanish if he looked away.
The softness of his voice caught him off guard, any witty remark he had planned died in his throat. "You've definitely had way too much to drink," Izuku giggled.
Katsuki was about to snap back at him but his back stiffened and his eyes went wide before he threw up all over Izuku's car. Izuku was horrified.

Katsuki woke up the next morning on the couch of his shared apartment. His head was throbbing and his throat was dry as sandpaper. The sun was too bright for his eyes, and his clothes clung to his skin. The faint smell of vomit assaulted his nose as he tried sitting up.
"Hey! He's up guys!" he heard Kirishima call out, his voice too loud for his ears.
Katsuki groaned, shutting his eyes again and pressing his palms up to his eyelids, rubbing them as if it would make his headache disappear.
"Yo," he heard a voice. He opened his eyes to see Sero in front of him with a bottle of water and a stupid grin on his face.
Denki spawned from somewhere Katsuki couldn't tell, "Heyyy Bakugo! You seemed like you had fun last night" he elbowed him lightly and smirked.
Katsuki snatched the water from Sero's hands and chugged it, the ice cold liquid instantly relieving the dryness of his throat.
"Shut up Kaminari, are you making fun of me," he scowled at him.
Denki put his hands up with a smile, "nah I just had no idea about you and Midoriya being a thing."
Katsuki growled and stood up so fast, almost falling over. "Shut up, we're not a thing" he muttered to him before making his way to the bathroom.
