Mirio had just gotten his breath back when he came in the door. He was flushed, sweaty, and fresh from a run, but he felt good. He loved the feeling of warm blood pumping strong through his limbs, it always made him feel so energized and ready to tackle the day. It was the reason Mirio could never work out too hard during the evening hours, otherwise he’d be too wired to go to sleep on time. The last time Mirio had gone for a late night run, he’d pestered Tamaki until two in the morning until he finally crashed into bed. 

Early mornings were perfect. Not too hot, the sun was out, it gave him a nice burst of life for the day, and when he came back, he got to see Tamaki still rolling around groggy in bed.

Mirio tried to be quiet coming in the door so that he didn’t disturb his lover, but the sound of the key in the lock had already stirred Tamaki. The boy had been starting to wake up anyway, but was fighting the “five-more-minutes” battle with his alarm.

Unlike Mirio, Tamaki liked to do just about everything after the sun went down. While Mirio went to bed at 10 like a reasonable human, Tamaki usually lurked about until the early hours of the morning. He liked being awake at night and just about the only time he felt comfortable outside was when it was dark. Not to mention, Tamaki liked to take runs through the nearby woods when the sun started to go down. He liked the chill of the night air and the heat from indoors always felt so nice after being outside in the cold for a while. And the best part, when his skin was especially flushed from the nightly breeze, Mirio held him in his lap to warm him up. 

Even though Tamaki was sure that was just an excuse for Mirio to get his hands on him.  Not like Tamaki was complaining.

Tamaki glanced over at the clock and saw it was only about 7 in the morning. They didn’t have class for another hour and Tamaki wasn’t one to stress about his appearance anyway. It took him twenty minutes max to get ready and if he missed any wrinkle on his uniform, Mirio usually straightened it out for him. 

Tamaki liked bed. Bed was warm. He could discretely look at Mirio from bed and secretly hope that the blonde would decide to be lazy for once and crawl in with him. Just about the only thing Tamaki liked to do in the early morning was cuddle.

And with the way Mirio was looking in his compression leggings, Tamaki had a few extra ideas what they could fill an hour with.

Feigning like he was still sleeping, Tamaki rolled onto his side to face the rest of their shared dorm room while peering through mostly lidded eyes. Even though Tamaki still technically had his own room, he spent so much time at Mirio’s that it was official in everything except paperwork. Tamaki could count on one hand the number of times he’d actually slept in his own bed — alone — in the past few months. It got cold. And lonesome. And then he was deprived of the wonderful view.

His dark eyes followed Mirio around the room, watching him kick off his shoes and almost leave them strewn in the middle of the floor before placing them next to the door. Tamaki had tripped over them one too many times. It almost made him giggle. It was cute the way Mirio smiled like he was expecting praise later. Tamaki made a mental note to thank him for not killing him later on their way out the door.

Mirio straightened and lifted his arms over his head in a deep stretch while Tamaki’s eyes raked over ever single muscle. He’d worn the shirt with the sleeves cut off deep down the sides, making it possible for Tamaki to see the long, toned silhouette of his chest and the slightest hint of his stomach. His gaze fell down, snaking along the curves of Mirio’s strong legs, knowing how tight they could squeeze around his hips and loving the way they were currently shoved into the shiny black fabric. With the slight glisten of sweat on his skin, Mirio looked golden and it was making it hard for Tamaki to lay still. 

Soon that wish of Mirio crawling into bed with him had turned from cuddling into something far different. Now he wanted Mirio to cross the room and slowly — teasingly — peel his shirt off over his head. But, in his fantasy, Tamaki really wanted Mirio to leave those bottoms on. The way his ass looked in those leggings was enough to drive him crazy. It looked so full and since he’d just gone running, Tamaki could tell it was would feel so nice and tight in his hands. Mirio was so sensitive too. Whenever Tamaki started groping at him or kneading the flesh of his bottom, he always got so wound up to the point of whining. It was such a stark contrast from how he carried himself the rest of the time.

There was a favorite memory that floated through Tamaki’s head, one where Mirio had leaned over his desk and offered Tamaki a distraction from homework he didn’t want to be doing.

Mirio had looked so impish. He’d smiled so wide at Tamaki and had hovered close to his face. With his hips raised and wiggling, it obvious that he had wanted something. Mirio had run his hands over Tamaki’s slender chest all the way down to curves of his hips to palm at the front of his jeans while he’d asked, ‘Do you have something nice for me?’

That had been a fun afternoon.

Mirio had never bottomed out for Tamaki before so that marked the first time. And he’d done it so well. Wriggling more and more in bed while trying to keep quiet, Tamaki remembered just how tight Mirio had been when he slid inside of him. Mirio’s voice had been so different when he was taking rather than giving, it was still deep and still rang out from his chest, but he sounded so... so needy. Needy for him.

‘Fu—uck! Baby, you- you’re so— big!!’ Mirio’s head had rested against the desk in pained expression of pleasure and his fingers had curled around the edge of the desk when Tamaki was finally, fully inside of him. Even just putting his dick inside of the boy’s ass had turned Mirio’s skin a flushed pink and they’d had to wait a good long while for Mirio’s body to adjust before he was even ready to think about Tamaki fucking him properly. He’d been so surprised — or maybe impressed— at just how huge Tamaki’s cock was that it was now pretty rare for Tamaki to be the one getting fucked.

Most of the time, Mirio was the one gunning to get screwed. Mirio had a way of pawing at Tamaki that drove him wild. His palm would somehow always find the front of his slacks and his lips seemed to be stuck on Tamaki’s neck. It made Tamaki smile a little. Mirio was so much bigger than him. He was so muscular and looked so manly, but there wasn’t much he loved more than getting down on his hands and knees, raising his hips up into the air, and slamming his ass against Tamaki to fuck himself on the cock he loved so much. Tamaki giggled— but also found it so hot that it was now impossible to hide the fact the fact he was awake and wanting something.

Tamaki was now obviously wriggling under the sheets, shifting his thighs and trying not to grind against the hand that had found its way under the covers and to the front of his shorts. That... and his eyes were now wide open and locked on Mirio, giving him away when the blonde turned suddenly to gaze at his sleeping boyfriend. Immediately, Mirio’s face brightened up like he’d just seen the sun for the first time in weeks, and he beamed at Tamaki with a cheerful voice.

“Good morning, sweetheart! I didn’t know you were up! Oh- ... shoot.” Mirio’s voice lowered a few pitches like it would stop him from further “disturbing” Tamaki. “Did I wake you up when I came in?”

“Mm-mm.” Tamaki shook his head no. He truly had such a way with words. How had Mirio described it again? Oh yeah- “minimalist”. 

“You whined when I got out of bed this morning. You almost didn’t let me up. Did you miss me?” Mirio cracked one of his shoulders in a stretch across his chest, before walking across the room to sit on the side of the bed. Tamaki was happy to have Mirio close, he could at least now he could poke his fingers out from under the covers and entwine them with the blonde’s. Though apparently, his little shimmying dance hadn’t gone unnoticed. Mirio pulled back the covers, revealing the massive hard on that Tamaki had going. “It looks like you missed me pretty bad.”

Tamaki could practically see a little floating pink heart shoot out of Mirio’s eye when he winked.

His face lit up in a bright red blush in response, earning him a soft chuckle from Mirio. Where was the use lying or trying to deny it? He was clearly hard and Mirio was already making good use of it. He knew what Tamaki liked to see, knew the exact buttons to push to get him talking and to get him honest. He threw a long, strong leg over the side of Tamaki’s hip and straddled him, giving the best view possible of the ass he had been drooling over.

Tamaki groaned softly when Mirio’s hips ground down onto his hardened cock, rubbing himself against the stiff length and feeling the friction through layers of fabric. He was looking over his shoulder at Tamaki as he started moving his hips back and forth across the other’s groin, brushing their dicks together but also teasing the black haired boy with his tight ass. He knew just how much Tamaki wanted to buried inside of it, he could feel how horribly Tamaki’s cock wanted to plunge in deep to fuck him hard, but he wanted to hear him say it.

“Someone’s excited this morning.” Mirio lifted his hips briefly, hovering only an inch or two above Tamaki’s waist, and slid a hand down into the other’s shorts. Tamaki couldn’t help but whimper when Mirio pulled his cock free, feeling heat shoot straight down to his groin at even the lightest of little touches. Mirio had seen it plenty of times, but every time he pulled it loose, it was like he was shocked by the size all over again. Mirio wasn’t small by any means, in fact he used to think he was pretty well endowed. Then he sucked Tamaki off for the first time. No one had ever made him gag before and he’d certainly never teared up from giving head. Tamaki didn’t even have to try. No wonder it always drove Mirio to scream every time it screwed up inside him. Mirio wanted it just as bad as Tamaki did by this point, but was better at playing a farce. He liked to have fun.

Mirio’s hips were grinding with more energy. He could feel the heat bubbling up in his own body, finally pushing him to remove his shirt and toss it to the floor, unknowingly giving Tamaki everything he’d wanted. Every little bit of friction was delicious, but it wasn’t nearly enough. For either of them. Mirio tried to keep his voice steady even if he was starting to turn desperate with Tamaki’s now free cock sliding past his clothed entrance, teasing at what he could be having. 

“It feels like my handsome boy wants something.” Tamaki was so weak to pet names. Whatever little embarrassing noises and moans he’d been trying to hold back came pouring out now. Every time Mirio laid it on thick, he was completely powerless and forgot what self control was. Which was perfect for Mirio. He didn’t think Tamaki had anything to be embarrassed about. His voice was sexy as hell when it got gruff and demanding with lust.

“I think I have an idea of what my cute, special boy wants, but—“ Mirio raised his hips up and locked his hands behind his head, letting Tamaki take in the sight of his back arching and hips curling towards him, giving the most wonderful, delicious curve to his ass.  Even half clothed, Mirio looked near pornographic like this. And then, suddenly, he brought them down hard, mocking how it would look if Tamaki were actually fucking him. “How will I know— if he doesn’t tell me?”

Tamaki’s heart was ready to hammer straight out of his chest. His hands were still frozen on the bed even though he wanted to bury his fingers in the flesh of Mirio’s ass and hips. He looked so good bouncing and grinding on his dick in those tight pants. He could see the hint of his skin peering through the stretched fabric and with the way he leaned back like this was all a show for Tamaki— it left him speechless and stupid hard. It was overwhelming, it felt good and there was so much attention on him. Tamaki apparently made Mirio feel that good and he was willing to go to these embarrassing lengths to get it?

Not meaning to offend, Tamaki looked away from Mirio’s eyes peering over his shoulders. He wanted to say it, the words were right on the tip of his tongue, but refused to cough up out of his throat. Even if he could have just raised his hands up and held him in place that would have been good enough, but he was stuck still. Embarrassed because he was so embarrassed. Which made him more embarrassed and red in the face.

“Okay, okay. I’m sorry, I’ll stop and go shower off. “ Mirio sighed, but it sounded happily defeated, and smiled at Tamaki. Maybe he wasn’t actually in the mood. Sometimes he was just too nervous and Mirio would never force his lovely boy into anything. Kissing did just fine. “Maybe next time, my sweet bo-“

“W-Wait...wait...!” Mirio, who had just climbed off of Tamaki, stopped and sat back down on the edge of the bed. He was patient and ran his fingers through Tamaki’s soft, black hair, pushing it away from his eyes while staying perfectly quiet, letting the other have all the time he needed. At least in this position it took the pressure off. “Please- I... I want you to ride me...”

The fact it took Tamaki that much effort to admit what he wanted somehow made it even hotter to Mirio. His face was a homogenous blush and even though Mirio could tell Tamaki wanted to look away and hide, he bravely held eye contact with him. What was best, was that Tamaki’s cool, slender fingers were now placed on the inside of Mirio’s thigh, grabbing at him and trying to nudge him back towards him.

“And can... you face me...?” Tamaki’s brows were knitted in a mix of worry and frustrated need. “I want to... look at you. It... feels better when I can see your face.”

God he loved this boy.

“Whatever you want, love.” Mirio dipped down and held the sides of Tamaki’s face while he kissed him, deep, sweet, and full of adoration that was making his heart burst. Mirio held their lips together while he climbed back on the bed and started to slide his leggings off. Tamaki peered at Mirio’s legs when he had to pull away to get them all the way off, looking at the skin as it was revealed like an unwrapped present. Mirio’s shorts went with them, revealing the entirety of his wonderful, strong body the second the fabric left his ankles. For a moment, Tamaki forgot how to breathe and just took in the sight.

Mirio looked so perfectly chiseled as he climbed on top of his slender frame. His muscles all moved like water as he swung a leg over his hips and squeezed his sides with his meaty thighs. Tamaki wasn’t sure when he’d lost his own clothes— he’d been too busy staring at Mirio’s waist and the way it dipped into his hips to notice.

Naturally, his hands found Mirio’s legs and ran all the way up to his sides, earning him a sigh from the blonde as he ground his now bare ass against Tamaki’s painfully hard cock. Mirio’s cheeks were already flushed and he looked so enamored as he rolled their hips together, obviously hungry and frustrated. Apparently, Mirio couldn’t take it anymore either. 

Hitting some kind of limit, Mirio leaned forward to the bedside table and fumbled for the bottle of lube. Wasting no time and throwing formalities to the wind, he popped open the cap and let the liquid ooze over Tamaki’s cock, watching it pool at the head before going down the sides. Mirio figured his insides could coat it evenly, he didn’t want to wait any longer.

His fingers wound around Tamaki’s arousal, heavy and rock hard, and guided the tip straight to his entrance, but paused, wanting to hear just a little more as he forced Tamaki to prod at him without entering.

“P-Please, Mirio. I want to fuck you so bad.” 

It was like music to his hears. 

Finally, Mirio’s hips sunk and Tamaki’s cock started to push its way inside. Immediately, the blonde’s head fell back in a long, shuddering gasp as his walls were pushed out of the way and his insides were deeply stretched with the intrusion. Were it not for Tamaki’s hands holding and guiding his hips, he would have lost strength and fell straight down on the full length of it. Tamaki at least had enough brains to remember to put it in slow. 

When their hips met, Mirio forgot how to speak. It was all he could to remember how to breathe. He could feel the pressure from Tamaki’s cock all the way up in his ribs. It was fitted so snug inside of him that Mirio swore it had gotten even bigger since the last time. It filled him so fucking perfectly. Even if it was big enough to hurt with how wide it stretched him, he ate it up inside of him and swallowed it all with his body. 

“Do you— ahhhh....! Do you like how your cock fits inside of me?” Mirio’s head, gasping and red, lifted back up and gazed down at the boy underneath him. Tamaki’s eyes were trained on him, raking over his body to take in the sight of his cock disappeared deep into his tight ass. Tamaki devoured every inch of Mirio’s glistened skin straight up to his face, looking at the evidence of just how much Mirio liked to take it. How much he liked to be filled and fucked with his cock.

“You look... so good like this.” Tamaki’s voice was louder, more brazen, and his grip was tighter, holding Mirio in place so he couldn’t do anything but be fully hilted atop his dick. “Please, move. I can’t take it.”

Like he would do anything else but make his sweet boy feel amazing.

Gripping the length tightly, Mirio shakily rose up and fell back down, giving Tamaki’s cock a few shallow but lewd strokes to get used to the size. Even though they had just fucked yesterday, it still felt like the first time. Even just starting to move, Mirio was already melting into moans and deep whimpers of arousal, feeling just how deep he was being touched and opened up.

It didn’t take long for the enthusiasm to kick in. The more Mirio got used to it, the more he started to like the slight burn of pain as Tamaki’s huge cock made room inside of his ass. He was being stroked so deliciously that he wanted more, he wanted to feel it deeper and wanted to feel the head of Tamaki’s perfect dick slam right into that wonderful spot inside of him it always found. 

“Does your massive cock feel good inside my tight ass? Do you like how I ride you, baby?” Every time Mirio got horny, his brain melted into perversity. He was all slutty praise and speech, wanting to scream out just how good he was feeling and always wanting to hear how good Tamaki felt. It was all the more motivation to fuck himself harder on the other’s dick. “Please, please—! Fuck! Please, say my name!”

“God, Mirio! God you’re so tight for me.” Tamaki’s hips suddenly snapped up while his hands pulled the blonde’s hips down and Mirio nearly screamed. Tamaki was so hard and he’d just rammed himself straight into his prostate, making his body crackle with pleasure while every spot inside him sang with white, hot, gasping pleasure. “I love it. I love your ass.”

Tamaki’s eyes hadn’t left Mirio’s face. He might have glanced down to watch the other’s cock bob as Mirio rode him, but he was more interested in how Mirio’s face seemed to be melting. His eyes looked hazy, like he was so lost in how good Tamaki was making him feel that he couldn’t remember how to think straight. His hands slid away from the boy’s hips and found Mirio’s ass, gripping the soft flesh in his palms, holding him and pulling him down to take even more of him.

God he was being squeezed so tight it almost hurt. Mirio’s legs were spread so wide over his waist and he was letting Tamaki fuck so deep into him. 

“Good...! So good! You’re doing so go—od!!” Mirio’s voice was rising. He was getting whiny and his hips were starting to get frantic. Even from here and without even touching it, Tamaki could see his cock twitching and starting to drool with precum. Mirio got desperate when he was close— hecouldn’t help it. He was so on display and so at the mercy of the pleasure Tamaki was throwing him into that it felt too good to hold back. He was so full of him, he wanted to feel even more of it, he wanted to feel Tamaki fuck him until he flooded him full of cum.

More. Tamaki wanted more.

With sudden force and a yelp from Mirio, Tamaki sat up and pushed the other’s back onto the bed. His legs were easily gripped into Tamaki’s arms and hoisted up to sit on either side of Tamaki’s waist, propping his hips up and giving Tamaki the perfect angle to absolutely ravage Mirio.

His hips thrust deep inside and instead of grazing that sweet spot, he rammed straight into it every single time his dick pumped back in. He was fucking him so hard and so fucking fast, it was amazing. Mirio’s brain felt hot and his back arched straight off the bed, arms stuck over his head and legs held tight— completely willing and taking to Tamaki’s wants.

“You’re mine.”

“Fuck!! Fuck, yes!! I’m yours!” Mirio was yelling at this point, unable to think about anything but how perfectly he was getting fucked. Loud, lewd smacking sounds were echoing from between his legs and his vision was cloudy with lust, but he could perfectly see how Tamaki was eating him up with his eyes. 

“More, I want to hear your voice.” Tamaki was so clear and so loud. It was fucking beautiful.

“Fuck me, baby! You’re such a good boy, fuck! Fuck my ass! It’s yours!! It’s all fucking yours!” Mirio was moving his hips hard against Tamaki’s, feeling so close it was hurting— aching. Drool fell out of the corner of his open mouth as all his breath turned into loud moans and mewls of pleasure, wanting to cum the moment the other started to fill him. “Claim it, claim me!!”

“You want me to cum inside you?”

“Yes!! Please, Tamaki!! Please cum in my ass!! Fill me with it!! It’s yours, it’s yours!!”

“M-Mirio!!” Tamaki curled over the other’s frame and dropped his legs, arms locking around the boy as his cock pounded into him, frantic and fast, until his teeth sunk into Mirio’s shoulder, groaning as he finally flooded inside of him. His cock twitched as he pumped Mirio’s ass full of warm, thick cum, feeling Mirio shoot off hard, not even able to speak as he came.

Tamaki glanced down as his softening cock twitched inside the other’s ass, seeing that Mirio had cum hard enough to get it all the way up to his neck and was now a panting, flushed mess underneath him. His lips were pulled back into a soft smile and his fingers twitched with the aftershock as he tried to get his breath back.

Mirio looked so fucking cute.

Tamaki collapsed on top of him but kept his arms locked around his middle, burying his face into Mirio’s pecs and groaning with relief. That was amazing. It was amazing every goddamn time and every time it took his breath away. Now he was left in the beautiful afterglow, where he didn’t want to pull out even if he was done for the time being and where he just wanted to be close.

Mirio was so warm. And his arms were so strong locked around him. His fingers were trailing up and down his spine, rubbing his back and holding him close. Perfect... absolutely perfect. They fit together so well. Even sweaty, tired, and covered in semen, Tamaki felt right at home and perfectly at ease snuggled up and pressed right to the other’s chest.

He could hear his heartbeat perfectly here.

“Baby... babe... baby.” Tamaki moaned softly when Mirio called for him. He was starting to fall back asleep. He was comfy. “Baby, we still have class to go to.”

“Mm-mm... no class... just this.” Tamaki locked his arms tighter around Mirio and screwed his eyes shut tighter, determined to fall back asleep buried between his tits and pressed flat to his chest. They were already in bed. And they were gonna be late anyway. This was fine.

“Babe, we need to go otherwise it’s going to look suspic- Oi! Don’t fall back asleep! Babe!”
