Size Matters

Summary:

It took several years before finally reuniting at an Inarizaki reunion for the two to acknowledge the tension between them that everyone else was very aware of.

It’s been wonderful—perfect, even.

Except - except, Aran won’t have sex with him.

Now, don’t get him wrong; he and Aran fool around; it was impossible not to when they rarely see each other and can never seem to keep their hands off of one another when they do.

But it’s always Kita receiving with Aran's mouth, occasionally his long, thick fingers, but never his dick.
---
After being together for so long, Kita thinks it's time he's finally fucked by his boyfriend and long time crush - Aran. Except, Aran has been holding back. Hopefully advice from his old kouhai will help Kita get what he wants.

Notes:

it's Kita's birthday which means I'm posting one of my favorite threads as a full ao3 fic!

enjoy!

Work Text:

Kita enjoyed having control over most things in life; his rice farm and his schedule were prime examples. It kept him calm and at peace. What he didn’t enjoy was the lack of control in his newly formed relationship with Aran.

It took several years before finally reuniting at an Inarizaki reunion for the two to acknowledge the tension between them that everyone else was very aware of.

It’s been wonderful—perfect, even.

Except - except, Aran won’t have sex with him.

Now, don’t get him wrong; he and Aran fool around; it was impossible not to when they rarely see each other and can never seem to keep their hands off of one another when they do.

But it’s always Kita receiving with Aran's mouth, occasionally his long, thick fingers, but never his dick. And Kita knows his dick is worth having inside of him; he’s grinded and ridden Aran’s clothed cock many, many times. It wasn’t enough, though—not for Shinsuke, who’s wanted Aran’s cock inside of him since his third year of high school.

"I’m…larger than ya think, Shin." Aran chuckled one day as they lay in bed together, both tired and spent from the orgasms they’d just given each other.

"Aran-"

"Let’s just take it slow, okay? I don’t wanna hurt ya."

He wanted to protest more, but when Aran pressed another gentle kiss to his lips, he forgot all about it. But now, Kita was done waiting. It’s been months of dating, and still they are no closer to actually fucking. How could he convince Aran that he craved the idea of having his boyfriend’s large body hover over him, making him feel incredibly small and pounding ruthlessly into his ass until he saw God? How he wanted those large hands to grip his waist or hold on to those broad, dark shoulders while he succumbed to unimaginable pleasure?

Shinsuke wasn’t used to being cunning or sneaky in order to get what he wanted; usually, Aran gave him whatever his heart desired. Though he did know two hellions who could possibly help him,

"How did ya two get yer boyfriends to fuck you?" He asked, sitting in a booth at Onigiri Miya. Osamu nearly snorts out his water from his nose while Atsumu chokes on the onigiri he was chewing.

It was odd coming to the twins for advice; back in high school, the roles were reversed. They’d constantly pester Kita for answers on just about anything. However, both brothers shared a similar aspect of life with Shinsuke: they had very large boyfriends. Meian was a given with his height, physique, and hands that engulf any part of Osamu’s body that he touches. When they stand next to each other, Meian makes Osamu’s 185-cm stature look incredibly small.

Sakusa, on the other hand, may only be a few centimeters taller than Atsumu, but he had a presence that was larger than life, the same as the setter. His broad shoulders and tall, willowy body practically gave him a couple of inches over his boyfriend. Long, strong fingers wrap around Atsumu’s thin waist almost like a puzzle piece.

Surely, the twins would have sound advice—if only they would stop choking for 2 seconds.

Atsumu sucked in a deep breath, recuperating from that unexpected question: "What the hell do ya mean, Cap?"

Kita rolled his eyes. "Not your captain anymore, Atsumu." His brows furrowed in frustration. "It’s just—I can get Aran to actually—ya know. He’s afraid of hurting me."

Atsumu turned to Osamu, holding a palm out in demand, saying, "Pay up, scrub; I told ya Aran-kun was fuckin’ packing." Osamu grumbled, placing a bill into his twin's hand before looking at Kita, who was staring at them deadpan.

The chef scratched at his cheek and said, "I'm not sure if I have any good advice to give youightly., Kita-San." He blushed slightly "Shuu and I-"

"Samu here is a slut, and let Meian fuck him on the first date. The scrub didn’t have to wait long to get dicked down." Atsumu cut in, grimacing when his twin punched his arm with a scowl.

"Let me tell you what to do, Kita-san." The blond leaned forward in his seat, his eyes bright with mischief. Kita was all too familiar with "Ya gotta rile Aran-kun up. Make ‘em desperate to fuck ya orrrr." His lips curled into a smirk. "Ya take what ya want. Don’t let him make all the decisions."

"What do ya mean?" Kita tilted his head.

"What I mean is, ya take the lead in the bedroom, get on top of yer boyfriend, and fuckin’ ride him into the sunset. That’s what I did with Omi." Atsumu looked a little proud of himself for making such a lewd suggestion.

"I’m going to be sick." Osamu blanched, moving and taking another sip of water. "But the idiot is right—if yer tired of waiting, take the lead. Who knows, maybe it’ll bring Aran-kun back to the good old days when you bossed him around all the time." Osamu winks at the white-haired man. It was Kita’s turn to blush at that.

"Trust us, Kita-San; Aran won’t have any objections."

Kita took the twin’s advice to heart—so much so that the moment Aran walked through the door of his home, the farmer basically attacked him, pulling him into a frantic, sloppy, wet kiss while tugging at his clothes.

He wished he had a camera to capture the moment he shoved Aran back onto the mattress once they were fully naked and straddled those sinfully thick thighs. Fuck, one thigh was nearly as wide as both of Kita’s put together. He held back a moan as he took in their size difference.

It sent a fire burning inside of Shinsuke. "Shin." Aran breathed out, running his hands up Kita’s sides to land on his hips. Long fingers reached fully around his waist, nearly touching each other. "What’s gotten into ya?"

Kita leaned forward to brush their lips together, teasingly uttering, "I’m tired of waiting, Aran; I want ya to fuck me. We’ve waited long enough, don’t ya think?"

"Shit." Aran swore, his grip on Kita tightening. Okay-okay, yeah darlin’, whatever ya want."

The smaller man let out a happy hum while grinding his ass against his boyfriend’s deliciously hard cock. He could feel how wet and dripping Aran was for him, though Kita wasn’t much better. "I prepped myself for you."

Aran cocked a brow, humor swirling in those chocolate brown eyes. "Prepped yerself already, baby? My, my, you must have been desperate." He lifted his hips, making Kita mewl slightly. "What are you waiting for, then, Shin? Take what you want."

Kita took a moment to refresh himself before reaching back and taking hold of Aran’s long, thick cock. It was hard and heavy in his grasp, and he couldn’t help but stroke Aran, bringing his hand up and down in a teasing manner and running his thumb over the slit. He kept his focus on his boyfriend, watching the way Aran’s brows scrunched together and his mouth dropped open in pleasure. "Ah, fuck Shin!"

"Grab the lube, baby." Kita ordered, continuing his movements, "I need you nice and slick for me to take yer cock."

Aran scrambled to reach for the lube and practically threw it at a preening Kita. That’s right. He had all the control here; Aran was under his bidding. He bit his lip as he coated Aran’s cock with lube, making sure there was enough to completely coat it.

Raising onto his knees, Kita looked down at the man below him just as the tip of his dick pressed against his awaiting hole. "Are ya ready, Aran?"

"I've been ready for ya, baby." Aran grins up at him with that perfectly boyish smile that sent his heartbeat skyrocketing.

Not delaying what he'd been waiting for all these years, Kita slowly sank down on Aran’s cock, his mouth parting at how much his boyfriend was stretching him. It ached, it burned, and it was addicting. He needed more.

"Aran." Shinsuke threw his head back once he was once again sitting on top of Aran’s thighs, filled to the brim. "Yer so deep." He moaned, clutching onto that bare, broad chest and digging his nails in.

Aran let out a shuddering breath, as if he were trying to ground himself. "Look how well yer taking me, baby." He brushed his fingers along Kita’s jaw. "Are ya alright?"

Tilting his head down, the white-haired man could only smile. "More than alright. I’m going to start moving now, okay?"

Aran chuckles under his breath. "Whatever ya want, baby, remember?"

Instead of answering, Kita rose up and quickly sank back down on his cock, creating a steady rhythm. His thighs shook at the effort to keep it up, but Shinsuke was determined; he was going to show his boyfriend what they'd been missing out on all these months. "Oh god." Kita whines as he bounces up and down, impaling himself on Aran’s hard dick. "I've been wanting this for years; ya feel so good."

"Yeah?" Aran panted out, holding onto his waist for dear life while pressing his hips up, meeting Kita thrust for thrust: "Me too, darlin’; yer so tight around me, squeezing me like ya don’t wanna let go."

Kita’s cries of pleasure grew louder and louder with each thrust. He shook his head as the burn in his legs began to be too much. "Aran, I can't-I-'' His breath catches in his throat at a particularly hard thrust.

Aran sits up, keeping Shinsuke in his lap, reaching to tangle his fingers into white hair and pull his head back while being so, so deep inside of him. A large, thick tongue licked along the side of his neck. "Is my baby getting tired?"

Kita whimpered slightly and nodded his head. He could feel his boyfriend’s laugh rumble against his chest before his world spun and he was placed on his hands and knees, Aran pressing his chest into the mattress while lifting his ass in the air.

Without another word, the burly man sank back into him harshly. "Ah!" Kita arches his back, crying out in ecstasy, feeling that monster of a cock reach into the deepest parts of him.

"Yer so cute, ya know that?" Aran coos, starting at a particularly brutal pace, "Thinkin’ ya can take my cock and order me around at the same time? I don’t think so, darling." He thrust in between each word, making Shinsuke sputter and moan.

Aran sets his palm on his lower back, the entirety of his hand spanning the width of his waist. It had Kita’s toes curling, "Fuck. Yer waist is so fucking tiny, Shin." He pressed deep inside and grinded his hips. "So small, so perfect, just for me.

"Aran! Please." Kita begs, holding onto the sheets below him tightly, trying to catch his breath. His boyfriend leaned over to hover over his body, never slowing his pace. His broad shoulders and muscular biceps practically hid him from the outside world.

Kita felt his body relax, feeling so safe underneath Aran like this. It was all he had been dreaming of. "Please what? What are ya wanting, baby? Tell me, and I’ll give it to ya." Aran nibbled on his ear, his breath burning against his skin. "Ya know I will."

"I want to come; I need to come, Aran." Shinsuke sobs out, pushing back to meet Aran’s harsh thrusts. "Harder, harder, more!"

"Ya want to come, baby?" Aran asked, his hand traveling down the length of his body until he reached around to press against his stomach, where it was bulging.

Oh god.

Kita could only nod and breathe out a small "Yes."

Aran sat back up, keeping one hand on Kita’s stomach and the other finding its place, holding his waist once again. "I’m going to make ya come, Shin, but yer only going to come from my cock. Ya think ya can do that, baby?"

"Yes, yes, yes, please."

Aran let out a dark, low chuckle and began fucking Kita fast and hard, rocking into his hot, wet hole and taking in every moan and mewl that escaped his darling boyfriend’s mouth. Fuck, baby, yer so good for me." He grunted, pulling at Kita’s hair again, tilting his head to the side to kiss him fiercely, whispering the words against his lips.

"Aran I’m-"

"Close Shin?" Aran asked, biting and licking along his jawline, not caring about any potential marks he could be leaving. "Come on, love, you can do it."

Fuck, those words shouldn’t sound so hot coming out of Aran’s mouth, but they did, and they had that familiar, burning heat building up inside of him. He clenches his hole tightly, making Aran’s movements grow erratic. Good, he wasn’t the only one who was close.

Aran pressed his hand harder against Kita’s stomach, almost stroking his own cock, causing the smaller man to squeal against him and tighten his ass even more. "I’m gonna-"

"Come for me, Shinsuke."

"Aran!" Kita gasped, his spine arching, as Aran thrust up into him one final time before he was cumming and spilling into the sheets below him. His thighs shake and tremble with the effort to keep himself upright; his arms give up; and his lower half lies pliantly on the mattress.

Aran kept fucking his ass after that, chasing his own release while his tiny boyfriend jolted from oversensitivity, eyes rolling to the back of his skull. Reaching his climax, Aran buried his face into Kita’s hair, groaning lowly as he came deep inside the man below him.

Silence washes over them while they both catch their breath. Aran exhaled deeply and slumped to the side to spoon behind Kita, keeping himself sheathed inside the other man.

He nosed against his neck, pressing soft and gentle kisses here and there. "Shin?

"Mmm?" Kita answered sleepily. "Are ya alright?" He asks, pulling him closer to his chest.

Kita snuggled back against him and said, "I’m wonderful, Aran." He sighed happily. "How was it?

Aran chuckled lightly, pressing another kiss to his neck. "It was perfect, Shin. Better than anything I could have imagined."

"Worth the wait?" Shinsuke asked teasingly.

Aran huffed, sounding almost pouty. "I should've done this months ago."

"Give me 10 minutes, and we can do it again." Kita snickered, rubbing his cheek against Aran’s bicep.

"Oh really?" Aran laughed loudly this time, holding him tighter against him. "Did I just awaken a monster in you?"

Kita turned his head to look over his shoulder at the other man, raising a brow. "Unless you think you can’t handle another round?"

His taunting caused that oh-so-familiar fire to light up in Aran’s eyes, and Kita found himself lying on his back with his boyfriend hovering over him, smirking in a way that has his stomach fluttering: "Oh darlin’, ya have no idea what I can handle."
