An obnoxiously familiar ringtone cut through whatever meager sleep he'd fallen into and Aizawa didn't have to have his eyes open to feel the twitch of annoyance in his bottom lid. He reached blindly to answer the damn thing with a noncommittal attitude, phone laid haphazardly against the side of his face.

The grunt of his voice was thick with lingering sleep. "If you're not dead or dying, you're about to be." 

"Shou." Not dead or dying. "Buddy. Pal of pals. You busy?"

"I'm sleeping."

A bark of laughter. "You're always sleeping!"

Not dead or dying, but about to be, then. 

Aizawa didn't bother replying. Not much to say. Sleeping was in his wheelhouse as a beloved and enthusiastically practiced hobby. If he had the option to be sleeping, he usually was. It was rare that it actually happened at night, though, and Aizawa was trying not to hold the interruption against his best friend. 

"...can I come over?"

One bloodshot eye cracked open like dried, unfired clay. From the mattress on the floor, he could see a hint of moon through the mess of his bent up shades. Over halfway across the sky. After 2am, at least.

"Whadd'you want, Zashi?" Aizawa rumbled thickly, eyes falling shut. "It's late. Already said I'm sleeping.”

"You wanna fuck?" Blunt. Offered so quick it could be an icicle snapping off a rooftop.

Aizawa appreciated the expediency of it, not having to wait five minutes just for Hizashi to get to the damn point, but it didn't endear him enough to give anything but a grunt of irritation.

"Know you'd rather mainline caffeine n'half a paychecks worth of coke than close your eyes like the rest of us but I just said—"

"Fuck Shou, please?"

Closed eyes closed tighter, making little ripple-like wrinkles in his forehead as Aizawa curled up pill bug snug under his blanket.

"You have Tinder and Grindr for a reason."

"I tried that!" Hizashi insisted on the tail end of a frustrated whine. "Shou, c 'mon! I wouldn't just call you for nothin'—"

"You would."

"—it's not like I ring you up for booty calls every other day—"

"You do."

"—but this is an emergency, Shou. A fuckin'— This is so not my usual call to get my dick wet. This is dire. I just spent over an hour eating this dame out— made her cum twice, Shou, twice! And she up and decided she was done! Just like that! Said she had work in the morning, practically shoved me out the door. I— fuck Shouta, I need to sink my cock into something."

He wasn't heartless. He could sympathize. Could empathize, even. Had his fair share of hookups that didn't end the way he'd hoped. Still.

"I gotta work tomorrow. M'tired, Zashi. Don't have the energy for you to take your frustration out on my ass all night and still function in the morning."

There was a long enough pause that Aizawa wondered if he'd dozed and missed the click of an end call, too lazy to lift the phone off his cheek to check. But it wasn't long enough to fall back asleep before Hizashi spoke up on the other end.

A final plea. "Please, baby? I'll do all the work. I promise you won't even know I'm there."

Baby.

It was just sex, Hizashi wouldn't die without it. He had two hands. But. He only ever called Shouta baby when he either really wanted something, or when he'd fucked up badly enough that he knew Aizawa was going to rip him a new one as soon as he helped unbury him from the shit.

"I doubt that very much." He grumbled. 

Obvious disappointment lined Hizashi's voice. "That a no, then?"

The sigh that left him was even more tired than Shouta himself.

"Come over."

He hung up before Hizashi could deafen him with a squeal or any kind of thanks and groaned at the distinct lack of sleep he was inviting into his bed. A betrayal of some kind, he was sure.

Aizawa dropped the overpriced pager beside him on the mattress and reached beyond it with a grumble, digging a half empty bottle of lube free of his shitty bedside. The click of the cap was loud in the dark and Aizawa considered it a bonus that he was already butt-ass naked under the sheets. Unwarmed lube spilled over his fingers and he grunted at the first touch of them to his hole. It was a quick and perfunctory process. Just enough effort spent to keep from risking a tear and nothing much beyond that. Little extra slick for a more satisfying slide, but that was that. Aizawa barely remembered to snap the lid shut before he was dropping the bottle somewhere and wiping his fingers on the sheets, already halfway to passing back out.

The nothingness of sleep was bliss in its purest form, but it wasn't meant to last. Aizawa dipped back into awareness the second Hizashi entered his bedroom but he didn't acknowledge it. Just let himself float right on the cusp as clothing hit the floor and he felt the bed dip beneath Hizashi's weight. A warm, lean body he knew just as well as his own slipped in behind him, threatening to invade his space beneath the covers. Shouta rumbled out a hum when warm lips and a gentle tickle of facial hair touched the back of one shoulder. 

"It's just me."

"Can smell her on you." He murmured in answer, just to be a dick. 

It wasn't untrue though. Aizawa could smell it on the man behind him. A little musky, probably from being buried between a set of legs, but mostly honey sweet. Rich like wine but not as heavy. Something with fig. Could have been incense, perfume, or maybe just a strong fabric softener, he didn't know. Didn't care, either. Just acknowledged that it didn't smell like Hizashi. 

"Don't be jealous, honey." Hizashi teased good-naturedly. 

Aizawa could feel the curve of that playful smile against his bare skin as the blonde scooted closer and skimmed the tips of his fingers down his side— along his ribs, because Hizashi knew he was ticklish there and reveled in being a pain— and back behind him to trail down between his cheeks.

He could feel the groan in Hizashi's chest through his spine as easily as he heard it when his questing fingers touched body-warmed lube and found his hole open and ready.

"Prepped yourself for me?" Breathless. Aizawa offered him breath of his own when he hummed in agreement.

Hizashi nosed at the nape of his neck through the tangled mess of his hair. 

"God you're good to me."

"God wasn't an especially active participant but think what you want."

Hizashi laughed behind him as he crowded in close, plastering himself to Shouta's back with one willowy arm draped around his waist. He was already hard. Aizawa could feel the steel balls of Hizashi's piercings at the small of his back, silken iron laid up against the roundest part of his ass, and he enjoyed the blip of silence as Hizashi settled in. The arm around his waist disappeared, though not entirely. He could feel it in the brushes of skin against skin as his best friend gripped his cock and led it to the hot, slippery hole Aizawa was generous enough to provide for him.

The second he was lined up, that arm was back around his waist, tighter than ever. Holding onto him by the core as Hizashi pressed his face into his neck.

"Deep breath."

Aizawa obeyed and took a big one. In — Hizashi's core tensed behind him and the pressure against his barely-prepped hole increased until the tight ring finally gave way, letting Hizashi's length slide home in one smooth stroke. Out — he made the effort to push past the sudden ache of being stretched too full, shaky on the exhale, Hizashi's forearm tensing around him as he settled. In and Shouta remembered how to relax; out and everything in him went lax. Another breath and he was able to enjoy the subtle almost-vibration at his back as Hizashi nearly quivered, buried in his heat.

With how hard pressed he'd been on the phone to get off earlier, Aizawa expected Hizashi to go for it as soon as he let up around him. He could feel how much Hizashi wanted it in the tell-tale flex of his cock buried deep, enjoying that as much as it must have pained his friend to wait.

But after a full minute the man behind him still hadn't moved.

"What are you waiting for?" He murmured.

A hand far less calloused than his own pet through the thicket of dark, wiry curls just above the flaccid swell of his cock, not yet interested enough to wake up and harden.

"Said you wouldn't even notice me, didn't I?"

Aizawa chuckled at the teasing comment. "Hard not to notice a cock in my ass."

Hizashi's neatly clipped nails pressed into bare skin low on his belly, barely firm enough to really be felt, but his hole still fluttered around the thick intrusion in his guts at the hint of sensation.

"You love it."

He did love it. Loved being full, always had. Liked feeling Hizashi there at his back. Especially liked not being pushed further and further out of his sleepy window by the rough clap of flesh meeting flesh.

A sweet smiling mouth he knew was wicked pressed soothing kisses to the sensitive crook of his neck. Aizawa shivered, he always did. The nerve-endings there had always been responsive, even more so than his cock sometimes. And that was before he started keeping the tender column covered with his scarf.

"Close your eyes." His eyes were already closed but Aizawa knew what he meant anyway.

Another kiss to his neck, another shiver.

A quiet whisper from the loudest man in the world made Shouta want to offer him another. "I said I'd do all the work too. Let me."

Aizawa swallowed and Hizashi gave him a glimpse of what he'd be agreeing to when he directed his hips in a single, lazy roll. It did little more than press his pelvis even more firmly to the thick ass already pressed up against it but Aizawa could feel the subtle movement deep inside and it pulsed heat through him. It felt good too. Really good.

"I just need a hole, baby. Just needed something hot and tight to be inside of."

Baby. Again.

Shouta was weak to it and he knew it. Knew it in the way his already lax body sagged back against Hizashi's. In the way his breath stuttered just a little on the exhale.

"M'going back to sleep then."

Hizashi didn't acknowledge him with more than another press of lips to sensitive skin but Aizawa could feel the tense and release of well trained muscles at his back. Could feel the flex of Hizashi's cock inside of him. Stationary but not still.

It was easier than breathing, to drop back off.

Aizawa could sleep anywhere, in any condition. Bed, couch, desk, floor. Hot, cold, light, dark. Didn't matter. A chance to sleep was a chance to sleep and he took every opportunity given. 

He didn't usually dream. From one blink to the next, Aizawa most often dipped into a quiet emptiness when he slept. A rare luxury, and a boon. Especially for someone in his line of work. But that wasn't always the case. He did dream occasionally, just like anyone else. Sometimes good, sometimes bad.

Aizawa wouldn't consider what he was doing dreaming. Per se. 

He wasn't awake, didn't feel awake, but he didn't feel like he was asleep either. Awash with heat at his back and low in his groin, all of it cocooned around him like a personalized sauna. Brushes of bare skin. The tickle of hair not his own. A roaming touch. Full and starting to ache with it. Pleasure. Low, throbbing pleasure that wanted to be known. There was an awareness, understanding just beyond his reach. Awake enough to know, sunk enough not to recognize.

It wasn't clear how long he'd been in that sticky, molasses heavy in-between but Aizawa came awake slowly to the feel of Hizashi rolling behind him like a wave, cock still buried to the hilt inside him, but rocking shallowly. 

Sweat clung to both their bodies, lubricating the movements between them. Effective in erasing the friction of it. Hizashi panted soft as a kitten just beneath his ear, shaky and obviously trying to stay quiet. Failing, but only just slightly. His hand was roaming his chest, stroking it as he brushed over the pebbled peak of his nipples. 

An insistent throb drew Shouta further from rest, dragging slow-to-respond attention down to his dick, finally hard. Aching with freshly acknowledged insistence.

A roll of his hips, and a luckily well-timed twitch from his cock nudged Shouta's prostate and he groaned quietly.

It was enough to alert Hizashi to his freshly woken state and he moaned in tandem, like the call and response of a bird. Clever fingers found one of his nipples and rolled it.

"You feel so fucking good, Shouta." He panted into his neck.

"Touch my cock." Shouta rasped, words half slurred, and choked on the sound he made when Hizashi went right for it. Abandoning his chest to wrap long, damp fingers around the head of his dick.

Hizashi squeezed around the tip, and Aizawa clenched around him in return. 

"Wet."

He was. Aizawa could feel it in the immediate, slippery glide as Hizashi dragged the meat of his palm over his leaking slit and down toward his frenulum. Polishing the crown.

His whole body shook in a rough tremble, breathing coming too ragged to be anything close to under control.

Aizawa made a gasp of Hizashi's name, fingers finding his thin wrist with a squeeze, and his best friend immediately knew what he wanted. They were too well versed in each other for it to be any other way.

Arousal slicked fingers formed a loose cup around the sensitive head and Shouta bucked into it. The rough bump of his tip into Hizashi's wet fingers made him groan and he was greedy for that sharp, sunburst of pleasure. Moved his hips in short, jabbing thrusts to chase after it. Quick and shallow. Bunny fucking into the loose grip and drowning in the kaleidoscope flares of sensation that kept bursting behind his eyelids.

Hizashi had no qualms with the direction things had taken. He was cursing quietly into the sweat-dampened pocket of his neck. Nosing at him there as they fell into an easily grasped rhythm; Hizashi pumping into him shallow and equally quick to help push him into the cup of his fingers.

It didn’t take long to get him there and Aizawa wasn't ready for it yet.

"Too soon." He choked, and Hizashi groaned, falling still with no small amount of effort when Aizawa did, a needy shiver slipping through both their bodies.

That wasn't exactly what he wanted, though, and Shouta wasn't afraid to speak up.

"More."

A questioning sound, rare for them. Hizashi took a guess and dragged a tight fist down the full length of his shaft, drawing a choked sound from Aizawa’s throat as he bared down hard on the length inside of him in response. Bucking his hips hard, once, with nowhere to go.

He shook his head, starting to pant, throbbing in Hizashi's grip.

"For you." He clarified roughly.

"Christ, so good to me. So fucking good to me." Hizashi praised between panted out breaths mirroring his own.

The grip around his cock disappeared and slipped lower. A confident hand cradled his balls in a warm, secure hold, just the way he liked, and Aizawa groaned with approval as Hizashi finally drew back and pushed in.

It was a smooth, steady glide. Slow. Rubbing the head of Hizashi's cock over his swollen prostate each time he sunk in, dragging the pierced ladder of Hizashi's shaft over his stretched hole. Shouta's heavy-lidded eyes went hazy with it. Mouth going slack in a broken rumble of sound as Hizashi took his time, working himself from base to tip inside of his body with painfully even strokes.

The introduction of more fulfilling movement pushed a satisfied moan from Hizashi's lungs with nearly every stroke. He moved in a wave at his back, dragging his cock torturously along the lit up, tender walls of his passage as he surfed. He'd been open and filled for a long time, no idea how long but a while. Long enough that he was sensitive with it; stretched rim hot with sensation. Each pass over his prostate, each blissful, textured drag of Hizashi’s piercings over his rim as he sunk back in had Shouta nearly matching his best friend groan for groan.

They fed each other like that, movement and sound and slick, messy passion tangling them together; hotter, tighter, more desperate.

Hizashi was a song at his back. Enjoyment and desire pouring out of his mouth without words. Aizawa loved when he got like that. When he lacked any of his inherently performative nature— too wound up and needy to run his mouth with streams of filth, too wrapped up in how good it felt to moan loud enough for the neighbors to hear. There was an authentic quality to it that Present Mic often lacked, but Hizashi himself had in spades, and it drove Aizawa so high, so fast, that he felt his balls draw up in Hizashi's palm.

"Close—" Aizawa warned him gruffly. He abandoned the hold on Hizashi's wrist to reach back and take hold of his hip instead, able to dig his fingers in and find better purchase. "Want to come. Please."

Shouta didn't know if it was the please, or just the vocalized confirmation that he was close and wanted to get off, but it drew a long, far-reaching sound from Hizashi's throat and he felt the other's steady rhythm momentarily falter.

"Your balls feel so full." Hizashi squeezed them gently with a groan and a fresh flare of heat burned through him. 

"Make me come, Hizashi—" Shouta rasped, because he could, relishing the throb of Hizashi's cock when he said it.

They moved in perfect tandem. Hizashi driving in, slow and hard. Aizawa pushing back to meet him, grinding into the cradle of his hips. His fingers dug into Hizashi's hip each time he pulled back, grip trembling like he was fighting the urge to drag Hizashi back into him because he was. Need rose. Pleasure rose with it. Waves of pulsing heat like the radiation of a solar flare and Aizawa could hardly breathe as it swelled in his body, gathering at the base of his spine.

Hizashi had a sixth sense for what he needed, learned but impossibly intuitive, and Shouta shook when he not only released his balls to grip him tight and stroke his shaft, but buried his face in his neck to mouth at tender skin there. Sucking kisses going straight to his cock and making him leak all over Hizashi's fingertips with every pass.

The arm that'd remained mostly inert underneath his pillow reached back for his best friend, calloused fingers slipping into his hair, finding the back of his skull and holding him close as Hizashi drowned him in sensation.

"If you stop I'll kill you." He said, nearly choking on the embarrassment that came as a hot, additional burst of pleasure when his voice broke near the finish line.

"Do it," Hizashi begged between hot pulls of his mouth, pulls of his fist, "fill up my palm, baby."

That word and Aizawa was gone.

Back arched off Hizashi's chest, fingers gripping his hair like a lifeline, pulled tighter than a bow string. Shouta could practically feel the sharp fwip! when Hizashi's fingers dragged over his slit and the arrow released. His hips bucked with every shot, body clenched up tight and milking the length inside of him as he spent all over Hizashi's hand, filling his palm just like he'd asked.

The body behind him tensed right as Shouta relaxed and he groaned in encouragement when Hizashi abandoned his spent dick to grab hold of his middle with a soiled hand. Hizashi was wrapped around him like a limpet, steady rhythm tits up as he let go and fucked him desperate and right on the brink. It took less than a handful of strokes for Hizashi to drive in deep and stay there with the loudest cry of the night, cock pulsing inside of him. Throbbing as he slicked him up inside with what felt like a massive load.

Drowsy exhaustion made itself known immediately and Aizawa went lax against the rumpled and sweaty sheets, trying to catch his breath as his eyes got heavy.

Hizashi pressed a lingering kiss to the throb of his pulse as he eased out with a wet sound and a harsh breath from both of them and Aizawa suddenly remembered that he'd been sucking on the skin there.

"Did'ju leave any marks?"

Hizashi reassured him that he didn't and the release of worry over hickies that didn't exist had him sinking lower. Or they did until Hizashi started to peel himself away from him.

Aizawa grunted in quiet, subtle displeasure and Hizashi reassured him a second time with a kiss, this time with a hint of teeth, to the roll of his shoulder.

"Calm down," He was calm. "I'm just cleaning us up."

The reminder that he'd let Hizashi come inside of him, and that it would inevitably leak out, had Aizawa burrowing deeper into his blanket in the closest thing to a pout that he ever got.

"Clean plug in the toy box." His cheeks warmed but they were hidden anyway. "Use it."

Bed empty, he could hear Hizashi rummaging around in the box in question. The noise stopped when he must have found it but Hizashi still said, "You sure? You'll be sore with it in all night."

Shouta ignored the warning.

"Said what I said."

Even with eyes closed and his back to him, Aizawa could sense Hizashi's shrug. He didn't have to hear the pads of his feet to sense his retreat, either, and Shouta told himself it was the glow of light behind his eyelids that let him know exactly where Hizashi was in the apartment.

He came back with a damp washcloth and clean hands. Warmer than Shouta would have bothered with for himself, and didn't ask him to move as he wiped the drying mess from his waist and his softened length. Shouta heard the rag hit the ground somewhere close to the laundry basket. Hummed when a gentle hand spread him open and eased the plug into his well used hole.

Hizashi hummed too. A pleased, high note song of a thing so different from Aizawa's own. He wanted to feel it against his back, at least for tonight.

"You staying?"

The bathroom light flicked off and Hizashi's voice came through even more clearly in the dark. "You cool if I do?"

He reached back and lifted the covers in invitation. "Want you to."

His wish was granted when Hizashi practically dove in behind him, more chilled than he had any right to be, feeding another pleased noise to him through osmosis when the broadest part of Hizashi's chest settled against his back.

Aizawa was already on his way out, sated with balls empty. Comfortable. Wrapped up in his clingy, limpet best friend. Silken hair he knew he'd wake up with a mouth full of currently spilled out across his pillow. Willowy arm back around his waist, breaths synced up without trying. Nothingness tugged at the edges of his awareness and he longed to follow. Intended to, in fact, but still made time to nestle back into Hizashi's frame. To take his hand and curve his grasp further up his chest so he could comfortably keep hold of it.

Hizashi made a quiet sound of approval, squeezed him gently, and Aizawa was out. Last thought running through his head that he always slept better on the nights he could stand to let Hizashi stay over.

He came back-to sometime later— long enough later that it was significantly lighter outside, but still before his alarm— to the feeling of Hizashi gently easing the plug out of his tender passage. Shouta didn’t fight the removal, letting it slip out without trying to hold on, and grunted to let the other know he was awake.

"I'll be quick," Hizashi murmured softly in breathless promise. "You won't even know I'm here."

He doubted that even more than last night but reached back to help guide him all the same.

He could feel the buzz of Hizashi's excitement at his acquiesce and Aizawa let that make up for the trickle leaking out of him and the ache he was sure to feel in his ass later.

"Deep breath, baby."

He took a deep one and let him in.
