When Yamada was given permission to basically have his way with Aizawa’s body whenever he wanted, he didn’t ever plan on really actually doing anything.
The whole thing had started when he’d woken up and realized he’d been thrusting against Aizawa’s thigh in his sleep, desperate and needy and horny because it’s been so long since they’d had sex due to their conflicting schedules. His eyes had slid open to found he’d been humping him, boxers stained with precum as he moaned needily into the crook of Aizawa’s neck while the other slept on. He’d guiltily told Aizawa of what he’d done the night before, and was met with a simple,
“Why didn’t you take it further?”
Yamada had blinked.
“Because you were asleep.”
“So?”
“...That’s wrong!”
“We’re married and I trust you.” Aizawa had said bluntly. “Really, just have your way with me.”
He’d denied it, telling him he absolutely didn’t want to because there was just something inherently wrong about that!
But a few nights later, he laid on his back right next to Aizawa, who was also on his back, body relaxed and face soft, not marred by worry lines. Yamada always liked to appreciate the other’s body when he wasn’t looking, because he normally didn’t like Yamada staring at him for long periods of time.
It was a particularly hot night, so they’d kicked the covers off, and both were in boxers and undershirts. Yamada’s eyes trailed down Aizawa’s body, noting his muscled arms, his tummy with a bit of pudge mixed in with the muscle, tight boxers wrapped around thick thighs and a great ass he could spend hours with his tongue in.
More importantly, his cock, which was currently starting to strain a bit against his boxers-he shifted in his sleep and let out a low, sleepy noise that petered off into incoherent mumbling, followed by a snore. Someone was having a good dream.
He tried to ignore it for as long as possible, knowing if he watched the other become slowly turned on in his sleep, he’d want to just fuck himself on the other’s cock until he was waking up cumming. But every time Aizawa shifted in his sleep, every time he let out a faint noise that Yamada’s highly-trained hearing picked up on, it all went straight down south.
Finally, he couldn’t take it anymore. He turned on his side, staring at his husband’s boxers, and the wet patch that had formed near the head of his cock. Balancing his cheek on his fist comfortably, he reached over and pressed his palm over the bulge, taking a moment to squeeze and hearing Aizawa’s sleepy reaction.
He moved his hand back up to slip his fingers beneath the other's waistband, before delving right into his pubic hair, running his fingers through the fuzz before gripping his cock. He pressed his thumb over the other’s slit, spreading the sticky precum around, and Aizawa let out another faint noise, one that sounded a bit happier than the slight frustration from before.
Yamada sat up for a second to pull the other’s boxers down to spring Aizawa's cock free before returning to his former position, taking a moment to admire it.
It wasn’t particularly big nor small, nothing very special about it, aside from the fact that it belonged to Aizawa and that meant he automatically loved it more than anything else in the world. He cautiously gripped his shaft, glancing over to see if the other was still asleep. He was, but his brows were furrowed adorably and his cheeks were red.
Yamada stroked the other slowly, keeping his eyes fixed on the movement of his hand, feeling satisfaction as more precum dribbled from Aizawa’s slit. Aizawa moaned in his sleep, long and low and considerably louder than before, his legs spreading just a bit wider, hips jerking up lazily into Yamada’s hand. Yamada moaned as well, watching the other’s reactions, knowing he was feeling pleasure even in his sleep. Yamada let go of Aizawa’s cock, which was met with a confused and needy whine.
Yamada got to his knees on the bed before clambering as quietly as he could across Aizawa, his knees pressing into the mattress on either side of Aizawa’s thighs. He’d pulled his boxers down, and now his cock stood free. He took a moment to make sure Aizawa was still asleep, before lining their cocks up together and wrapping his hand around them both.
Aizawa’s hips rolled up into his as he panted in his sleep, eyebrows furrowing and lips mouthing wordlessly, occasionally pressing together in a pout. Yamada pumped his hand to an established rhythm in his head, struggling to keep his volume down as he masturbated the both of them. He kept his gaze focused on Aizawa’s sleeping face, the way his lips moved in his sleep, his dark hair covering his forehead and a bit over his eyes, but still visibly asleep.
He remembered Aizawa telling him to just have his way with him, and he wanted very badly to lower himself on the other and move his hips until he could see stars, but that would risk waking the other up, and he wanted him to get as much sleep as he could. So for now, he’d settle with the hand job.
Aizawa came before he did, spilling across the both of their stomachs with a higher-pitched moan than before, his body relaxing against the mattress as Yamada stilled.
Miraculously, he was still sleeping.
Yamada rolled off of him, giving himself a few more strokes until he came into his hand, and decided that that hadn’t been...too terrible, actually.
He told Aizawa what he did the next morning, the other nodding along to his words. It didn’t happen again for another couple of days.
The second time it happened, Yamada decided to be a little riskier.
He sat on the other’s hips, rolling his shirt up to his chest, taking a long moment to admire the other’s body. The way his muscles were shaped, the pudge in his belly and expansive thighs, the hair leading to his crotch and his fuzzy thighs. The scars and nicks and bruises everywhere from hero work, most notably being the one on his elbow.
Yamada leaned down to kiss all of the blemishes he could find, six or seven on his upper torso alone. He leaned close to Aizawa’s sleeping face to press his lips into the crook of the other’s neck, before sliding his tongue out against it. He licked for a moment and Aizawa shifted beneath him before pressing his open mouth to the skin there, sucking and biting softly. He worked from the crook of his neck to his Adam’s apple, and then to his collarbones. He could already see the beginnings of a bruise blossoming on Aizawa’s neck, and smiled against his skin as the other moved beneath him, though he was still in deep sleep.
Yamada moaned against the other's skin as he took Aizawa's flesh between his teeth, kneading, sucking, wanting to warrant any kind of reaction from the sleeping man, but getting none except the occasional snore and grunt. Deciding that he needed to move his mouth somewhere else, he moved past where Aizawa’s shirt was bunched on his chest and reached one of his nipples, hardened in the cool night air. He pressed his tongue flat against it before pulling away, feeling triumphant as Aizawa moaned in his sleep, back arching so his chest puffed out, just begging for Yamada to take one of his nipples into his mouth.
So Yamada did, closing his lips close to his skin and rolling it with his tongue, relishing in the response he was given. Aizawa’s nipples were sensitive and messing with them was always guaranteed to give him some reactions, but Aizawa usually tried to stifle those reactions. Now, however, Aizawa was asleep, and had no filter, moaning openly as Yamada suckled. The sleeping man’s hips rolled up into his, where’d he positioned his cock just over the other's. With satisfaction he noticed the growing bulge in Aizawa’s pants, and dragged his tongue across Aizawa’s chest to his other nipple.
One of his fingers reached up to press lightly at one of the bruises on Aizawa’s neck as he sucked and played with his sensitive skin, all while their hips were moving against one another. His fingers traced teasingly across Aizawa’s chest, before taking his other nipple between his fingers and rolling it, tugging hard, eliciting a deliciously high-pitched mewl that shot a tingle of arousal down his spine. Aizawa’s hips rolled upwards, cock pressing up right against his ass, and he moaned around the other’s skin.
Aizawa’s back arched once again as Yamada pressed his teeth lightly to his nipple, nearly biting it, another moan mixed with a pant leaving his lips, deep and rumbly in his chest.
Yamada shifted his position, reaching both hands down to grip at Aizawa’s hips for better movement, and mouth still around the other’s nipple, began to thrust against him a little harder than before.
Aizawa panted desperately, hips canting upwards with no real rhythm, just desperate to get off in his sleep, shifting around as Yamada pressed them close together. He switched his mouth onto the other nipple, noting how the other one looked so wet and even swollen in the moonlight.
Aizawa’s hand brushed against his thigh and his fingers curled up against it, nails digging into his skin, and he gave another moan, though this time, it was loud and clear as his clothed cock jerked up right against Yamada’s clothed ass. Yamada could feel the precum smearing in his boxers and a feeling in his gut, knowing he was about to cum, but he didn’t want to-not yet, he wanted to keep this going on.
He stopped moving his hips, but Aizawa thrusted up against him again, mouth falling open in a groan, and Yamada stiffened before climaxing, groaning hard against Aizawa’s chest. He felt a bit overstimulated as Aizawa kept jerking up against him, and he straightened up, taking in Aizawa’s desperate features, expression loose in his sleep, mouth open and saliva trailing down his chin.
Yamada allowed the other to rub off against him until he came, before getting to his feet and going to change his boxers. In the morning, Aizawa complained about how gross he felt, and Yamada merely smiled and pressed a kiss to his cheek.
The third time, Yamada told Aizawa what he was going to do beforehand and got his consent to do it.
He waited nearly an hour for the other to fall asleep, unable to contain his excitement, and when Aizawa’s soft snores filled the room, he eagerly began it.
Aizawa had gone to sleep naked, as per his request, and Yamada took in his naked body greedily, moving to suck bruises on his thighs in his eagerness for tonight. He pressed wet, sloppy kisses around his thighs and his crotch, and it took all of his willpower to keep from needily sucking at the tip of his hardening cock. He eventually sat back on his heels and spread lube across his fingers, before pressing one into Aizawa.
He pumped his finger slowly, twisting it all around and doing his best to not disturb the other, though he’d learned by now that Aizawa being a deep sleeper usually meant he could literally fuck the other while he was snoring and he wouldn’t wake up. Probably.
He slid another digit in, opening and closing his fingers in a scissoring motion as he spread the other, and Aizawa rolled down on his fingers in attempt to lazily fuck himself onto his fingers. Yamada allowed him to do so, feeling his wet insides, spreading him as best he could, before sliding out. Aizawa made a needy little noise in the back of his throat, still rocking his hips, though now he had nothing to fuck himself with, toes curling and eyebrows furrowing.
Yamada spread more lube onto his fingers before taking the little toy he planned to use for tonight-a vibrator he’d bought months ago but never had the chance of using. Once ensuring everything was nice and slick so nothing would be uncomfortable, Yamada pressed the vibrator against the other’s hole and slowly pushed it inside. Aizawa’s thighs spread wider and he groaned, face screwing up in his sleep, arms moving up and spreading out as his back arched. Yamada pushed the vibrator until he couldn’t see it from where he sat, and slid his finger back out once he’d made sure it was secure inside.
He had the remote in his hand, a slider that had a setting of one being hardly noticeable and fifteen being a very hard vibration that he wasn’t entirely sure wouldn’t wake Aizawa up.
He turned it to four, and watched Aizawa writhe, thighs squeezing together as he made another noise in the back of his throat, body flushing. He moved to turn on his side, but Yamada reached over to prevent him from doing so. So Aizawa settled back against the mattress, hips rocking slightly as his cock began to leak, mouth dropping open but no noise coming out.
It remained this way for a while, a few mewls sounding from Aizawa’s throat, and Yamada watched transfixed by his reactions, watching the way his toes curled, and the noises that escaped his mouth sounded a bit frustrated, like he was having a dream where he just couldn’t get the pleasure he needed no matter how much he begged.
He slid the remote so it was on eight, and Aizawa reacted beautifully.
For a moment, he was stiff, but then his legs spread wider, hips moving hard, hands moving to rub at his chest in his sleep before moving down to his thighs, though he didn’t continue any further. He was gasping and drooling onto his pillow, entire face red, moaning openly. He was very wet, moving his hips around and seeking release in his sleep but finding none, just the vibrating feeling against his prostate.
Yamada’s own body was flushed as he watched his husband react in a way he’d never seen before, the other man unable to hide or stifle his actions and noises in his sleep where he had no control.
Yamada was beginning to think he’d developed a kink.
He lowered the settings again, and the noises Aizawa made began to border less on arousal and more on quiet, needy frustration. Yamada palmed his own arousal with his hand, staring hard at Aizawa’s downturned mouth, his lips pressed together, noises humming in his throat.
For ten minutes he palmed and rubbed himself, watching as Aizawa eventually relaxed against the mattress, growing used to the vibrations that weren’t giving him the pleasure he was wanting.
The current setting-six-was then pushed to eleven, and Aizawa’s reaction was gorgeous.
His back arched, thighs shaking, moaning loud, so loud for a second that Yamada was actually worried this had somehow hurt the other, but then Aizawa fell back against the mattress, panting, hips moving frantically as he searched for something, anything to get off on, trying to fuck himself on a cock that wasn't there. He turned over, but this time Yamada let him, watching the other rut into the mattress, cock rubbing against the sheets, dirtying them with precum and sweat, ass spread, panting against his pillow, which was now wet from all the saliva that had leaked from his mouth.
Yamada began stroking himself fast, because god, that was super fucking hot, and he had a super fucking hot husband who sounded wonderful and looked even better. He pushed the settings up to thirteen-which was as far as he got before Aizawa gave out a cry that was almost like a scream and came against the bedsheets, body stiff before practically flopping against it, panting heavily. His eyes fluttered before sliding open, and Yamada shut the vibrator off as he slid forward.
“...why is everything so wet?” Aizawa got out after a couple of seconds. He’d made a mess of the bedsheets due to a combination of cum and sweat, not to mention drooling all over his pillow.
“Just know you had a great time.” Yamada said, sliding his fingers inside of Aizawa, in which the other gave a tiny mewl in response. He slid the vibrator out and set it aside, before moving to finish himself off, eventually cumming into his hand. When he opened his eyes, Aizawa had fallen back asleep, still on his back, ass still spread. Yamada knew he had done that on purpose. Damn him.
A few weeks passed and Yamada didn’t initiate anything while Aizawa was asleep, and they had sex twice while awake, Yamada getting the chance to use the highest vibrator setting on Aizawa both times.
One particularly stressful evening he fell asleep before Aizawa got home from patrol, spread out across their bed. He slept for maybe about three hours, and woke up feeling uncomfortably warm. Limbs heavy from sleep, he shifted, though found that he couldn’t move very much because there was something holding his hips in place.
Frowning, he blinked the sleep from his eyes, eyes taking a few moments to adjust in the dark, and realized that his dick was hard and engulfed in a wet warmth. Feeling a little more alert, he lifted his head to see that his pants had been undone and they’d been pulled off, hanging off the edge of the bed, his boxers nowhere in sight. Aizawa was bobbing his head up and down, face flushed, eyes focused on his work, hands gripping Yamada’s waxed skin to keep his cock in place.
“Oh...shit.” Yamada mumbled out in a moan, a little startled. Aizawa stilled before slipping his cock from his mouth, a trail of spit leading from his tongue to the tip of his cock, gripping his shaft tightly.
“You’re awake sooner than I expected.” He said, fixing Yamada with his dark gaze, eyes hooded, pressing his lips to his cock in a wet kiss. “I thought you’d sleep for another half hour.”
“Ah, well…” Yamada didn’t quite know what to say. He...had not been expecting this. At all. When Aizawa had given him his consent to to fuck him in his sleep, he hadn’t thoguht that the offer would go both ways.
He wasn’t objecting though.
“This feel good?” Aizawa asked, pressing his tongue flat against the veins on his shaft, still staring at him, and Yamada nodded, trying to prevent his hips from jerking upwards. Aizawa smirked, and Yamada took that moment to admire the drool and precum trailing from his lips onto his chin and cheeks, his face flushed, before Aizawa placed his lips on the tip of his cock and began to suck, eyes returning to focus on it.
Yamada groaned, folding his arms behind his head and watching Aizawa suck just on his tip, sloppy wet sounds filling the hot and heavy air. He felt Aizawa’s tongue flicking and licking at his slit, and gave a little groan, because fuck, this felt nice, but also, Aizawa was being a goddamn tease. The other’s fingers squeezed his cock lightly before pressing up against his balls, humming around the head of his cock.
Suddenly, Aizawa took all of him into his mouth, and he felt the tip of his cock pressing against the back of his throat, before the other was sliding him back out. He repeated this motion a few times, always seeming to somehow go deeper into his mouth, before stilling, wet slurping sounding like beautiful music to Yamada’s ears. Aizawa moaned around his cock and shifted, hollowing his cheeks, before he finally pulled away, Aizawa’s mouth an absolute mess from his current activity. He leanes forward to press more sloppy wet kisses to the head of his cock, eyes dark.
“Fuck, baby, you’re so hot.” Yamada moaned, and Aizawa shook his hair out of his eyes and averted them, cheeks growing redder. Yamada knew he liked the praise, and grinned.
“I never thought you’d actually do it to me.” Yamada said, closing his eyes. “You were so hot, so needy when you were sleeping. Were you needy tonight? Were you frustrated I wasn’t awake to fuck you into the mattress?”
“Hmm.” Aizawa hummed, returning his lips to the shaft his cock, licking and sucking on his skin just as Yamada had done to his neck weeks ago. He gave his cock a squeeze and Yamada groaned as Aizawa moved his hand up and down, pumping him slowly.
Aizawa took his tip into his mouth again and played with it, and Yamada felt his frustration grow, having woken up hard as could be. He really wanted to cum, and although seeing Aizawa suck him off was hot, fucking the other and cummining inside him five times was sounding really appealing at the moment. He sat up, adjusting his legs, but Aizawa didn’t glance up at him, eyes focused on his cock, face dark red. Yamada took this moment to take a mental picture of the scene, Aizawa’s swollen pink lips wrapped around his dusky member, both the inside and outside of his mouth wetter than he’d ever felt before. He reached to grip the other’s hair tightly, and they made eye contact-before he forced his husband down on his cock.
Aizawa yelped in surprise but did not complain at the motion, and Yamada began to fuck into the other's mouth, using his hand to maneuver the other’s head up and down, pulling tightly on his hair. Aizawa’s eyes were tearing up from his hair being pulled, face red, but he wasn’t making any move to stop or utter the safeword, tongue sliding up and around his cock as his face was fucked and Yamada moved desperately into his hot and wet throat.
“Shit, baby, you’re so good…”
The slurping wet noises of Aizawa around his cock were too good, almost too much, making his toes curl, his legs shake.
“So hot. I like seeing you cum and get all needy in your sleep, but it’s best when you’re awake.”
He grinned, noticing the way Aizawa was rocking his hips into the mattress, body shaky just a tad.
“You’re pretty horny, huh? Me too, thanks to you.”
His hands stilled in their motion, and he pulled Aizawa off of his cock with a delicious sound, thick wetness escaping Aizawa’s mouth as he panted against the mattress, getting their bedsheets wet. Yamada moved forward to tug at the other’s pants, and with his help they were shucked off the other.
“Hizashi…” Aizawa moaned as Yamada gripped his ass tightly, looking over at him with wider eyes. “The lube’s right next to you.”
Humming, Yamada reached over to grab the bottle before tossing it to Aizawa, who caught it. The other needed a moment to compose himself from the facefucking he’d just received, and proceeded to spread the cold lube across his fingers before bringing them to slide into his ass, biting the insides of his cheeks as he spread himself.
Yamada, meanwhile, took this time to undress completely, brushing strands of hair away from his sweat-slicked face and neck, before turning to look at Aizawa.
Sure, Aizawa was louder, needier, more visibly in need of release in his sleep, but nothing would ever beat him being awake, currently laying on his back, the sleeves of his shirt rolled up, knees bent as he crooked his fingers into himself, biting his wet lips to keep himself from making any noises.
After a while, Aizawa relaxed against the mattress, and Yamada slicked himself with lube, careful to not stroke himself too hard lest he cum too early. Positioning himself at Aizawa’s hole, he slid in slowly, hands gripping Aizawa’s thighs and forcing them apart to get in as deep as he could go.
“This okay?” He asked.
“Yeah.”
Yamada leaned forward, and Aizawa’s legs adjusted so his calves were over his shoulders, legs spread wide, and Yamada leaned close, his hands sliding into the other's and pressing him into the mattress. He began to thrust his hips, and Aizawa threw his head back. Yamada realized now just how worked up and horny he was, his husband moving his hips along with his own, trying to fuck himself subtly with a faster pace than Yamada was going, desperate to feel good.
Yamada pressed his lips close to the other’s neck, sucking, biting. “You okay, baby?”
“Yeah.” Aizawa panted. “I just…”
“Need to get off?”
“Yeah.”
Yamada began thrusting harder, faster, and Aizawa reached between them to grip his cock, pumping it at the same rhythm. His other arm was resting beneath his head to give it leverage, face flushed as he stared at his own cock and at Yamada sliding in and out of him. Yamada could feel his legs trembling, and moved his mouth up to press a kiss to Aizawa’s.
Aizawa moaned deep into it as his tongue pushed against his, feeling the inside of his mouth, sucking, and he realized just how wet Aizawa’s face was with a mixture of sweat and spit and precum.
Yamada was enjoying the feeling of Aizawa’s ass, enjoying the way his cock was brushing against his walls, enjoying the fact that Aizawa was wet and his cock was dripping and what little noises he allowed to slip out of his mouth were needy mewls and the occasional moan that got cut off short.
Yamada could feel himself about to reach his tipping point, and gave a few more hard thrusts, each one punctuated by a gasp from Aizawa, before cumming deep inside him. He pulled out, panting, staring at Aizawa’s ass, where his cum was pooling at his hole, leaking out, thick and hot and white and mingling with his sweat. Shit, he’d really filled him up this time.
Aizawa was still pumping his cock, moving his hand fast up and down, moaning louder as Yamada moved out from underneath his legs, so now his toes curled against the mattress, hips jerking up against his hand.
Aizawa’s eyes were focused on his cock as he stroked himself, gripping his head hard before moving down to briefly rub at his ballsack, and then sliding his wet hand up and down once again. He was zoning out, body rocking, cum pooling out of his ass, mouth dropped open and letting out moans and pants and god, Yamada just felt so fucking privileged to witness it. Suddenly, Aizawa’s eyes flitted over to meet Yamada’s, making direct eye contact and keeping their gazes connected as he moved his hand faster, gasping.
“Hizashi.” He mewled needily, voice deep and desperate, face screwing up a bit. “Shit, you filled me up, I can feel it, Hizashi, I feel so good…”
Yamada cleared his throat, face flushing. “Do you?”
“Yeah…” Aizawa’s back arched, and he gave a long, drawn-out moan. Seconds later, he was cumming all over his stomach, before collapsing completely against the bed, chest rising rapidly.
Neither of them said anything, coming down from their orgasm highs. Yamada’s eyes raked over the other, taking in his sweaty flushed skin, his relaxed muscles, pudgy tummy with cum splattered all over it, a bruise forming on his neck.
Yamada closed his own eyes, thinking of the past few weeks, where he’d had the time to practically worship every inch of Aizawa in his sleep, and by the time he opened them, realized Aizawa was passed out.
Smiling, Yamada moved to get a washcloth, because no matter how much Aizawa loved Yamada cumming inside him, he always complained about the way it felt later on.
