Fun in the Funhouse

Summary:

“Ok, maybe this isn’t easy,” Eijirou said after they passed by the same portion of the maze for what felt like the 100th time. He turned to Katsuki and rubbed the back of his neck.

“No shit,” Katsuki replied, unsure why he let Eijirou take the lead in the first place. The guy could get lost with a compass in hand and a map in the other.

“Sorry, Kat,” Eijirou apologized, but something about his tone didn’t sound apologetic at all.

Katsuki narrowed his eyes. “Did you personally go out of your way to get us lost?”

And that’s when Katsuki saw it. That fuckin’ goofy smile that stretched across Eijirou’s face when he was up to no good."

 

Katsuki gets dragged along by his friends to a local summer fair, and finds himself lost in an obnoxious funhouse with Eijirou.

Notes:

Been a while since I did a smutty one shot with my boys Baku and Kiri. Felt good to write this out.

I hope you enjoy <3

Work Text:

A trip to the summer fair in blazing hot weather. 

 

“It’s gonna be fun!” Denki said. 

 

“Come ooooooon, you know you want to,” Mina chimed in. 

 

“If you go, I’ll win you a game prize,” Eijirou finished with a wink. 

 

And they were wrong. 

 

Katsuki was not having fun, and bless his boyfriend’s heart, but Eijirou could not win a single game of blow darts or ring toss, either. So instead of fun, Katsuki humored his friends while suffering under a hot sun and sweating his ass off. The black T-shirt he had worn was stuck to certain parts of his body, bringing more attention than necessary to his pecs and shoulders. Katsuki kept catching Eijirou checking him out, and it was amusing. 

 

“Oooooh, a funhouse!” Mina shouted, pointing in the direction of a large attraction blurring their vision with neon lights. “I haven’t been in one of those since I was like… a teen!” 

 

“Yeah, for a reason,” Katsuki replied. “Who the hell wants to walk around in one of those as an adult?” 

 

Eijirou, Denki, and Mina raised their hands at the same time while Kyouka and Hanta laughed at the enthusiasm. 

 

There was no point in arguing. Katsuki hoped the funhouse had air conditioning as Eijirou took his hand and the group of friends walked over. Excited chatter flowed between them, aside from Katsuki who was quiet with eyes transfixed on the abomination of lights dancing in front of them. 

 

If he looked too long, Katsuki was certain his eyes would start to burn. 

 

The bored teenager who was clearly unhappy with his summer job hardly looked up from his phone when he stopped the group at the entrance of the funhouse. “Two at a time,” he said, pointing towards a sign listing the rules. 

 

Two at a time. Katsuki liked the thought of that more than going in all together. The idea of getting lost in a house of illusions with a bunch of idiots was a waking nightmare. 

 

A bunch of idiots that he loves, of course. 

 

Mina and Denki groaned, the only two upset by the disruption of plans. Hanta wrapped an arm around Mina’s shoulder and kissed her on the cheek. Her slight frown instantly turned to a warm smile. 

 

“Gross.” Katsuki couldn’t help himself. 

 

Hanta laughed, and Mina stuck out her tongue. 

 

“Wait, you guys, I have an idea,” Kyouka said, grabbing everyone’s attention. “Why not make things a little fun? Let’s see who can get through the quickest.” 

 

“Oh, you are SO gonna lose!” Denki immediately pointed his finger at Hanta, who offered a confused gesture in return. 

 

This was even better than going two at a time, because now it was a competition. Katsuki liked any excuse to kick someone’s ass, regardless of the activity. 

 

“Hey, man! That’s not very sportsman-like of you,” Eijirou said in defense of Hanta. 

 

Denki patted Eijirou on the shoulder. “Wow, using another word for manly? Look at you, picking up a dictionary.” 

 

“A thesaurus,” Katsuki corrected. 

 

Denki tilted his head at him. “I’ve never heard of that dinosaur before.” 

 

“Are you fucking s–” 

 

“Are you guys going in or not?” the teenager asked, cutting Katsuki off before he could finish his insult. 

 

“Yes!” Denki replied, and slapped his tickets into the teenager’s hand. “We’re first!” he announced as Kyouka pulled out her phone to start a timer. 

 

“No cheating, everyone!” Mina made sure to remind the group, “Or else!” 

 

“Or else you’ll make us watch trash tv for ten hours straight, right?” Hanta asked, already knowing the answer. 

 

Mina winked and popped her gum. “Right.” 

 

Off went Denki and Kyouka, stepping through the string lights and tassels that covered the doorway to the funhouse. The material crinkled and crunched as they stepped through, and Katsuki watched them disappear, wondering what horrors lie ahead. 

 

Five minutes passed, or at least that’s what it felt like. Mina and Hanta were next, waiting with their phone to track the time. The teenager reached out a hand for their tickets, and waved them in without a word. Mina flashed Katsuki and Eijirou a peace sign before her and Hanta strutted into the vibrant void. 

 

“We’re next,” Eijirou said excitedly. He bumped their hips together and smiled down at Katsuki, his enthusiasm earning a roll of Katsuki’s eyes and a humored, short laugh.

 

“You’re an idiot,” Katsuki replied with a small smile.  

 

They paid their dues with the last of their tickets, and together pushed past the tinsel and stringed lights until they found themselves in a rotating hallway. The walls were painted a glittery orange that shined bright from the pattern of neon lights on the ceiling, and the floor was sticky from all the people who had passed through that day. 

 

“These are so fun!” Eijirou shouted over the loud carnival music as he began running in the same direction of the slowly spinning hall. “I feel like a hamster!” he laughed. 

 

Katsuki shook his head, but there was a smile on his face. He easily passed through the hallway, and Eijirou eventually followed behind, taking in his surroundings as if he were in a whole new world. 

 

“You remember we’re in the middle of a competition, right?” Katsuki asked, turning to make sure Eijirou was keeping up. 

 

“Yeah,” Eijirou replied with a goofy smile. He reached for Katsuki’s hand, and planted a kiss on his cheek. 

 

“Then act like it,” Katsuki replied as he tugged Eijirou along. 

 

They stepped into a new room and were transported into space. Small stars gleamed against a black surface from the ceiling to floor. Even in the darkness, Katsuki could see the way Eijirou’s eyes shined with wonder. He was much more into the attraction than trying to find a way through. 

 

“There’s gotta be a door somewhere,” Katsuki said as he held one hand out and started to walk towards one of the walls. 

 

Eijirou did nothing to help, standing in the middle of the room and appreciating the illusion of existing among the stars. Katsuki wasn’t going to do the same, stuck on winning and only that. His hands blindly skimmed along the walls until finding a small latch, and Katsuki smirked to himself. 

 

“Let’s go,” he called to Eijirou, opening the door and letting light in from the next portion of the funhouse.  

 

A mirage of mirrors was waiting on the other side. Katsuki groaned and rubbed his face with his hands, not excited to map his way through a maze of reflections, but Eijirou seemed incredibly confident. 

 

“Easy!” he happily exclaimed. Katsuki looked at him, confused, but Eijirou only smiled wider. “I’ll lead,” he said as he took Katsuki’s hand and started their journey through.  

 

And what a pain in the ass this part of the funhouse was. The tall mirrors kept them from being able to see overhead, and the space was so small, it was difficult to maneuver around without bumping into the frames. The room was growing hotter by the minute, and Katsuki really wanted to breathe fresh air. Each dead end was another reminder that they were wasting time, and Katsuki did not want to lose to his stupid friends. 

 

“Ok, maybe this isn’t easy,” Eijirou said after they passed by the same portion of the maze for what felt like the 100th time. He turned to Katsuki and rubbed the back of his neck. 

 

“No shit,” Katsuki replied, unsure why he let Eijirou take the lead in the first place. The guy could get lost with a compass in hand and a map in the other. 

 

“Sorry, Kat,” Eijirou apologized, but something about his tone didn’t sound apologetic at all. 

 

Katsuki narrowed his eyes. “Did you personally go out of your way to get us lost?”

 

And that’s when Katsuki saw it. That fuckin’ goofy smile that stretched across Eijirou’s face when he was up to no good. 

 

“You dumbass.” Katsuki rolled his eyes as Eijirou stepped closer. 

 

“I’ve been checking you out all day,” Eijirou pouted as he ran his hands down Katsuki’s sides. “I couldn’t wait until we got home.” He slowly dropped to his knees and looked at Katsuki with pleading eyes. “... please?” 

 

How could he ever say no to Eijirou? 

 

There was no way they were gonna win now, anyway. 

 

A smirk found Katsuki’s lips. “Don’t ask, Red,” he said as he ran fingers through Eijirou’s hair. “You know what I like.” 

 

Eijirou was fast. His fingers were at the button of Katsuki’s jeans in an instant, and the sound of his zipper came a second later. If he had been this determined to get out of the funhouse, they definitely would have won. But right now, that was a distant thought as Eijirou pulled down Katsuki’s pants and underwear just low enough to expose his cock. 

 

Just the sight of Eijirou below him had Katsuki hard, dick waiting for a warm mouth with little patience. The familiar flat tongue of his boyfriend licked its way up from the base of Katsuki’s shaft, and stopped at the head. Three flicks over the top coaxed a moan from Katsuki, and Eijirou gazed up at him like he hung the moon and the stars in the sky. 

 

“You drive me crazy,” Katsuki said as he traced his thumb down Eijirou’s cheek and across his jawline. 

 

He was met with a dreamy grin that didn’t last too long before Eijirou fully took Katsuki’s cock into his mouth and stole the breath from his lungs. A moan escaped him and he tipped his head back. Katsuki could only imagine the taste of his sweat and musk on Eijirou’s tongue from walking around in the sun all day. 

 

“You like the taste?” he asked in a husky voice while basking in the sight of Eijirou’s beautiful mountain of a body on his knees for him. Eijirou hummed his response, and Katsuki scoffed. “You’re nasty, Red.” 

 

No reply. Not possible with a dick down your throat. Eijirou merely picked up speed, tightening his lips and working his tongue up and down Katsuki’s shaft. The heat of Eijirou’s mouth forced more moans from Katsuki’s, and he felt himself starting to tip over the edge. 

 

“Wait,” Katsuki said as he took hold of Eijirou’s hair, stopping him from moving. Eijirou gazed up at him, eyebrows raised with Katsuki’s cock still down his throat. He looked so goddamn beautiful; a mountain of a man on his knees, all for Katsuki. Like a god bowing to a mortal, giving up every bit of his power for a chance at love. 

 

“I wanna fuck you,” Katsuki said in a heady tone, “Turn around.” 

 

Eijirou stood to do what he was told while Katsuki pumped his cock a few times with a tight fist. He helped Eijirou pull down his shorts and underwear, the two frantic and desperate for one another in the heat of the tiny space. 

 

Katsuki spit into the palm of his hand and wetted his cock as best he could. Fucking without lube was never preferred, but he was too horny to give a shit right now. “I’m gonna go slow,” he promised before adding more saliva to his fingers and circling the rim of Eijirou’s ass. 

 

Thick fingers spread across their reflection as Eijirou braced himself against the mirror, body trembling as he waited for what he had wanted all day.  

 

“Don’t break the damn thing with your quirk, got it?” Katsuki asked as he lined himself up with Eijirou’s entrance. 

 

“Got it,” Eijirou breathed with excitement.  

 

With the hem of his shirt between his teeth, Katsuki slid his cock into Eijirou’s ass at a slow, comfortable pace. He could see the look of pleasure on Eijirou’s face in the dozens of mirrors that reflected them, and couldn’t help but lean forward to press a kiss to the top of Eijirou’s tanned shoulder. 

 

“So pretty,” he whispered. 

 

Eijirou closed his eyes and tilted his head so he could softly nuzzle against Katsuki. He placed one hand on the mirror in front of them, and the other reached back to find one of Katsuki’s. “I’m ready,” he said in a reassuring voice. 

 

Katsuki pulled back his hips and fucked into Eijirou with a gentle rhythm a few times before switching up the speed. Skin slapped against skin, drowned out by the music blasting through the funhouse speakers that Katsuki could no longer hear. The expressions on Eijirou’s face were guiding his every move. Katsuki studied him in the reflection, unable to look anywhere else. 

 

And what he saw was a man slowly becoming a desperate mess. Katsuki smirked as Eijiro reached for his own cock and began to touch himself. “Getting close?” he taunted as he dug his fingers into Eijirou’s hips. 

 

“Y-yeah,” was all Eijirou could say, and even then, he stumbled over the single word. 

 

Katsuki didn’t have it in him to tease Eijirou for how fucked out he sounded, not when he was standing there on the ledge alongside him. He kept his gaze fixed on Eijirou and the gorgeous look of relief on Eijirou’s face when he came was enough to send Katsuki into a shaky orgasm of his own. He came hard and gripped Eijirou even tighter, moaning out his name much louder than intended. 

 

His hips stuttered through the last bouts of his pleasure, and Katsuki finished inside Eijirou before leaning forward to press a kiss between Eijirou’s shoulder blades. 

 

“God,” he groaned while trying to collect himself.  

 

The heat from the summer weather wasn’t making the cramped space they were trapped in any less hot and sweaty. Katsuki was certain they were going to come out of the funhouse looking worse than they did going in. 

 

“I don’t think god is going to help us with anything after what we just did,” Eijirou replied with a tired laugh. 

 

No arguing with that, especially with how lewd Katsuki’s cock looked as he pulled out of Eijirou’s ass. He tucked himself away in his pants and wiped the sweat from his forehead before helping Eijirou redress. Katsuki glanced at the floor where some of Eijirou’s cum had spilled, but couldn’t be bothered to care.  

 

“Was it worth it?” Eijirou asked, grabbing Katsuki’s attention as he turned to face him. 

 

“Ha?” Katsuki didn’t know what he was talking about. 

 

“You know, the fair,” Eijirou replied with a flirty smile. 

 

Katsuki laughed. “You’re an idiot,” he said before pulling Eijirou in for one last kiss. 

 

For once, he didn’t care about winning. 

 

Katsuki was always number one with Eijirou by his side, anyways.
