Three months after learning All Might’s secret
“Yagi,” said Naomasa. “If I understand correctly, you’ve been working for 48 hours straight?”.
Yagi let out a strained chuckle. “Well, you know, I used to go for five days straight! When Nighteye joined me he wouldn’t let me do any hero-ing past three days, but villainy never sleeps and-”. Naomasa shook his head slowly. “Go to bed, Yagi. You’re no help to others if you’re exhausted”. Yagi fiddled with his baggy black sweater, not meeting Naomasa’s gaze. “But… Tsukauchi, what if there’s a threat the others can’t deal with? I can just have a nap and I’ll be fine.” his voice was bold and steady, like he knew what he was talking about, but Naomasa heard the fear behind it.
Naomasa looked Yagi up and down. A skinny skeleton with comically drooping… bangs? antennae?, wearing a sweater underneath a dress shirt to hide the fact he was wearing an equally baggy hero suit underneath it. His piercing blue eyes (that were currently looking as far away from Naomasa as they could) were barely visible from underneath the sheer amount of bags, revealing his tendency to prioritise the problem over his own health. He didn’t look ready to deal with a super-threat, he looked ready to keel over. Wordlessly grabbing Yagi’s arm, he strode over to the big All-Might™ themed door showing where All Might’s living quarters were. Yagi’s eyes widened a bit as he got pulled forward and he stumbled with a yelp, but he didn’t try to fight back. Naomasa shoved him in front of the door, and Yagi sighed and pulled out his card to open it. As soon as the card scanned, Naomasa dragged him through the opening and went to investigate All Might’s home. “Seriously? A pile that big full of free promo stuff?” Naomasa sighed, unsurprised, as he pulled Yagi through his own home. “Is that where you got that rose-scented stuff you gifted me once? It didn’t wear off for like a week…” Continuing his journey while giving Yagi no room to respond, he found the bed.
“Here.” Naomasa said, manhandling Yagi down into sitting on the bed. “Get changed. No hero suit. I will notice.” Yagi’s face flushed a little, and Naomasa couldn’t figure out whether it was the idea of changing in front of him, Naomasa calling him out on the hero suit thing, or if Yagi literally didn’t know where his pyjamas were. He sighed, turning to exit the room, and in a more gentle voice, said “I’ll give you a few minutes to get changed”. Yagi spluttered at that, scrambling to sort through the mess on his floor. When the rustling stopped, Naomasa re-entered, finding Yagi in oversized sheep-themed PJs. Yagi’s face was even more flushed than it had been before, which Naomasa quirked an eyebrow at. “It’s just… I don’t really let people see me like this, you know? It was fine with Nighteye, because we… were… um…” he trailed off again, face flushing further. Huh. Naomasa hadn’t pinned Yagi as swinging that way. “Anyway! It just makes me feel vulnerable! That’s all!” Yagi continued, giving his best all-might-grin-on-skeleton-face. Naomasa sat down on a chair in the room. “Well, get to sleep, Mr. All Might, I do have to get back to filling out all the paperwork for the villains you’ve caught over the past 48 hours….” Yagi nodded, slipping underneath the covers of his bed.
A very awkward pause emerged as Yagi laid in his bed, Naomasa to the side, neither doing anything.
Honestly, Naomasa hadn’t really thought this through. Does he just… stay here? Does he check his phone? Stare? He continues trying to analyse the best way to act, waiting for one of them to break the tension. “I… get. um.” Yagi swallowed. “Nightmares. Memories. It helps if there’s…” He paused again, obviously unsure if he wanted to finish his sentence “...Another person in my bed?”.
…Fucking All Might just asked Naomasa to sleep with him. In a non-sexual way, of course, but combined with the earlier admission that he and Nighteye used to be a couple, it got Naomasa’s heart racing, and his own cheeks flushed a bit. “Of course. If you don’t mind, that is.” He shed off his own coat, hat, and various other clothing items not well received by beds, and slipped underneath the covers. Immediately, Yagi’s breath hitched, and he grabbed onto Naomasa. He looked more awake, but the good kind of more-awake. This close to each other, Naomasa could hear Yagi’s heart racing. “Um. This is a little weird but uh… I know a good way to put me to sleep?” Yagi said, his voice cracking and blushing, yet bold, looking like he knew Naomasa wouldn’t turn him down. “Only if you want to, though”. Naomasa raised another eyebrow at that, letting out a soft “Oh?”. Yagi bravely soldiered on “I fall asleep really easily after I get fucked”. Naomasa stiffened up at that as every part of his body stood to attention. He’d kind of expected something in that vein, but to have it said so bluntly was still embarrassing. “You’re asking me to have sex with you?”. Naomasa said, confirming he didn’t misinterpret what Yagi was saying. “If you want to go that far, yes. I said ‘get fucked’, but whatever you’re comfortable with is fine”.

How did Naomasa get here? Yagi (All Might of all people) sitting on the side of his bed, legs spread, as Naomasa kneeled and started to pull down the flannel pants that had cartoon sheep staring back at him. “You don’t wear boxers to bed?” Naomasa asked, looking up at Yagi. Yagi’s hands clenched the sheets a little more “Ah, no, I don’t.” Weirdo, thought Naomasa, and he worked Yagi’s cock out of the fly of his pyjamas. It was half-erect, not the All-Might sized dick one might have expected, but it wasn’t small either. It was quite cute, really, and Naomasa couldn’t wait to have it in his mouth. He imagined what he must look like, hyper-focused on Yagi’s dick, before he took a hand to it and slowly caressed Yagi’s balls. Yagi let out a moan at that, gentle and breathless, and Naomasa mulled over the fact that between cutting contact with Nighteye and All Might’s shitty sleep schedule, Yagi must not have had much time to touch himself. He let himself get closer, giving a little lick at the underside of Yagi’s cock, loving how it hardened a little more at his attention. He held the cock in his hands, giving it kisses along the top and then under the shaft, sucking on Yagi’s balls before saying hello to the head of Yagi’s now fully-erect dick. Taking another glance over the shape and size of it, he took it into his mouth, savouring the taste. Glancing back up at Yagi, he was mollified to see Yagi breathing heavily as he stared at him, eyes half-glazed already.
Naomasa started setting a pace as he sucked Yagi’s dick, trying his best to keep teeth out of the experience and trying to remember how to use tongue (it had been a while since he’d last sucked cock, to be fair), going slowly but steadily. He looked at Yagi again, gauging what he should and shouldn’t do by his expressions and faint moans. As Naomasa sped up a, the moans got louder. He was caught between fondling Yagi’s balls and playing with his own, coming to the conclusion that since he regularly jerked off and it had been a while since Yagi had, it might be more fun to see how many orgasms he could get out of Yagi before spilling his own load. Mind made up, he toyed with Yagi’s scrotum, feeling how plump it was. As Yagi’s cock slid back in his mouth, he savoured the taste of pre-cum, adjusting his head a bit to get the best angle on Yagi’s cock. “Tsukauchi….” Yagi moaned, and Naomasa thought to himself that now that he’d sucked Yagi’s cock, they were probably on first-name basis. Working faster, he felt one of Yagi’s hands thread through his hair, and several more moans (alongside “oh fucks”, “more”, and other sex-adjacent langauge) spill out of Yagi’s mouth. As they increased, Naomasa mentally prepared himself for a flooded mouth, and was faced with another dilemma; Deep-throat Yagi and swallow all of his seed (hot), get Yagi to cum in his mouth so he can taste it (also hot), or get Yagi to pull out and cum on Naomasa’s face (ALSO also hot)? Naomasa worked his way down Yagi’s dick to fully deep-throat him, mildly wondering if he could get the timing right to pull off all three. “Tsukauchi! I’m- I’m gonna!”. Smiling wickedly to himself, Naomasa sucked deeper, rewarded with a godly moan from Yagi. He tried pulling off to get a taste, but Yagi had both hands on his hair now, pushing him all the way back down on his cock. Yagi’s legs were struggling not to close in on Naomasa’s face, and Yagi bucked up and into Naomasa’s mouth for what felt like a solid minute before stopping and loosening up.
Fuck, Naomasa had felt cum run down his throat for however long Yagi had been bucking… God, he kind of wished he’d had Yagi in his ass instead. As Yagi pulled back, Naomasa sucked on the head of his cock, pulling out a last whimper from both the man and his dick as it gave up another shred of cum to Naomasa’s tongue, and Naomasa happily revelled in the flavour. It tasted like cum, mostly, just salty and bitter, but with a hint of extra All Might flavour that… vaguely tasted like the after-taste of like, every All Might-branded drink ever. He had a feeling he was either going to buy more of them, pop a boner drinking one, or both. Sitting back on his knees, Naomasa licked his lips, and took a look at his work. Yagi had one hand death-gripping the sheets, another covering his face as he whimpered again, his flaccid cock looking well-loved. The hand on his face came down for a second as he took a look at Naomasa, then back up as his cock gave a little twitch of appreciation.
“Hey,” Naomasa said, “You’re gonna need to look at me if you want me to fuck your ass”. His voice came out slightly huskier than usual, and god did he need to drink some water after having Yagi’s cock deep-throated for who knows how long, but it had the desired effect as another moan came from Yagi. “Here, turn around for me, I wanna start working on prepping you”. Yagi scrambled onto the bed and changed his pose, ass up in the air, but it was slow and sluggish. “Hah… you were really right when you said that orgasming makes you sleepy, huh?” Naomasa drawled, searching around the nightstand for lube. Finding what he was looking for (All-Might branded lube? seriously? they made that?) he finally got rid of Yagi’s pants, biting his cheek as he saw the start of the huge scar. He… didn’t know too much about it, honestly, but he wasn’t going to not fuck Yagi because of a scar, and he knew just enough about it to know it was a sensitive subject. “Hey, do you mind if I touch the scar?” he said softly. “Or should I avoid it?”. Yagi was still out of it, just moaning back “Doesn’t…. Hurt… Fine…”, so Naomasa took the opportunity to run his fingers along the scar, underneath Yagi’s shirt, and up to his nipples, giving them a friendly rub. He got a contented moan back, and retreated his hand in favour of pouring lube on his fingers and doing what he came here to: finger the shit out of Yagi’s ass. He ran a lubed finger around the rim of Yagi’s asshole, feeling the curves and folds of it. Rubbing it, he started pushing his first finger in, gently and slowly. His first finger went in easily, and after a few thrusts he added in a second, pushing in knuckle after knuckle until he could curl them, gently searching Yagi’s inner walls for the spot he knew existed. Brushing deep inside, he hit a spot that made Yagi give a full body shudder and moan, and he knew he’d found it. gently pushing in a third finger and scissoring, he hit Yagi’s prostate again, and again, his other hand copping a feel of Yagi’s dick. It was fully erect again, and slick with precum, so he retreated, thinking it might be more fun to see Yagi cum hands-free. He got back to work, speeding up the thrusts of his fingers slightly “Hey, Yagi, mind if I make you cum again before fucking you?” Naomasa stated, deliberately hitting Yagi’s prostate. He just got a moan in return, so he took it as a yes. “Hah, you’re so sleepy already… If you fall asleep after this, do you mind if I still…?” Yagi moaned again “Nighteye… used to… don’t mind…” he slurred. Naomasa felt a little bad for not getting clarification beforehand, as Yagi was both answering with fingers up his ass and half-asleep, but if Yagi said it was okay and Nighteye apparently used to do it, he could logically deduct Yagi probably wasn’t going to mind in the morning. “Mmhmm, and you don’t mind waking up with cum in your ass?” he crooned. “Plug… like it…”. And now he was wondering how many lives All Might had saved with a buttplug keeping cum up his ass. Spreading his fingers a little wider and making sure he continued hitting the prostate, Naomasa upped the speed again, whispering praise and compliments into Yagi’s ears. He got moans back in response, and he felt particularly pleased when a moan came in direct response to his words (The number one hero has a praise kink? Who would’ve seen that?). Soon enough, Yagi let out a particularly drawn-out moan, and he felt Yagi clench on his fingers as he came on the mattress. Naomasa continued thrusting his fingers right into Yagi’s prostate, which was the right move, as Yagi continued spilling seed onto the sheet for what once again was a nearly inhuman amount of time. Naomasa had kind of assumed that the deep-throating made him feel time was longer or that after that first load Yagi would have got rid of most of his stock, but seeing the fucking puddle on the sheets, his doubts were pushed to the wayside. Apparently Yagi just came like a damn bull. He would absolutely have to get Yagi to fuck his ass in All Might form at some point. For now, he finger-fucked Yagi through his orgasm, then dipped his fingers into the puddle of cum and tasted them. God, yeah, he was popping a boner when he drank All Might branded shit from now on, it was official. He wondered if Nighteye or Yagi had purposely made the drinks taste like All Might’s cum? It was a weird but hot thought.
Finally pulling down his own pants and lubing his poor, abandoned dick up, Naomasa considered what pose he wanted Yagi in. He got rid of both his and Yagi’s shirts before pushing Yagi up so that his head was on a pillow facing up, and lifted his legs up over Naomasa’s head. Yagi was fully asleep by now, tears still slightly in his eyes from cumming, and Naomasa thought to himself how lucky he was to be able to see Yagi like this. He took a bit to appreciate Yagi’s body, running fingers over every inch of him, before lining himself up and taking the plunge into that spectacular asshole. He had no trouble sinking himself in. He’d felt it through his fingers, but Yagi’s ass was tight, sucking him in like some kind of succubus and squeezing his dick in the best way possible. Naomasa felt kind of lucky he was lean and long, he didn’t think anything super thick would fit in Yagi’s ass. He groaned, pulling himself nearly all the way back out before pushing himself back in, setting a fairly fast and rough pace compared to what he did before. Naomasa couldn’t really help it, Yagi just felt so good, he’d avoided touching himself the whole time, and Yagi was asleep, anyway, so it’s not like he cared how fast Naomasa was going. He angled himself up to try and get Yagi’s prostate, and it took a few tries, but Yagi moaned and his dick twitched, so Naomasa knew he’d found it. Now that he knew how to hit it with his dick, he tried to figure out how to do that while rutting and squirming to get as much of himself inside Yagi as he could, moaning and groaning along the way. This pose was a good choice, Naomasa decided, as he saw precum leak out of Yagi’s dick onto his stomach, and watched his sleeping face contort in pleasure. He sped up, barely able to hold back from cumming right there and then, determined to make Yagi cum in his sleep. “Nigh eye…” Yagi moaned, reliving some previous good experience. Naomasa continued pounding into Yagi, enjoying his sleepy murmurings. Yagi’s eyes flicked open here and there, and Naomasa took the time to whisper praise at him. Yagi seemed fully comfortable the whole time, easily falling back asleep. Finally, as Naomasa was at the end of his rope, tears welling up in his eyes, Yagi came again with a scream, painting both his chest and Naomasa’s with his cum. The clench around Naomasa’s dick was too much and he rutted deep into Yagi, cumming with all his worth. He rode Yagi through what was initially both, but very quickly became just Yagi’s orgasm, panting hard as Yagi’s dick let out one last rebellious squirt.
Naomasa sighed, remembering that he’s forgotten to grab the buttplug Yagi had mentioned earlier. He shuffled them both over to the nightstand and dug around, quickly finding what he was looking for. Pushing the plug slowly in, he removed his member. A few drops spilled out, but Yagi successfully had a buttplug in and no Naomasa in, so he considered it a win.
…Now, what to do about the puddles of cum without waking up Yagi?
(As it turns out, Yagi is a very heavy sleeper and didn’t mind being kicked off the bed temporarily while Naomasa changed the sheets.)
~~~
The next day, Toshinori woke up feeling more well-rested than he had since he and Nighteye broke up had their argument. He sleepily recalled how he’d ended up in his own bed with Tsukauchi cuddled around him - Tsukauchi had insisted he go to bed, started him down until he was in bed, then… Toshinori flushed a bit. Ah, they had fucked. Or rather, Tsukauchi had made him cum twice then… he patted down his body and slipped a hand into his pyjamas, feeling the plug resting there. He remembered some of it, Tsukauchi looking down at him like that and- Toshinori stopped before he could give himself a boner. He hoped he hadn’t crossed a line or something without thinking, he’d love to have Tsukauchi fuck him again. He… probably should’ve talked about the sleep thing beforehand, now that he thinks of it. Tsukauchi seemed to get the memo, but he’d hate if Tsukauchi felt guilty about fucking his sleepy ass.
Well, he thought to himself as he snuggled in for another few hours of sleep, everything else could wait until Tsukauchi woke up, and then Yagi could deal with the morning wood he felt pressed up against him.
