Summary
     Aizawa doesn't particularly like taking photos often, but Shinsou is
     the one to change that.
     Aizawa starts taking photos of Shinsou when he isn't looking or
     paying attention and eventually starts taking bigger and bigger
     risks.
Notes
     I incorporated some stuff I saw on Tumblr in this fic!
     I've said it before, but this is my favorite pairing.
     (also there's some background Erasermic in here, mostly just in one
     scene. I didn't tag it because I didn't think people who like that
     ship wanna see teacher/student stuff)
See the end of the work for more notes
The first time Aizawa took a picture of him, he made sure Shinsou didn’t
notice.
He didn’t plan it the first time, either. It just… happened. Aizawa was by no
means a photographer, nor did he spend a lot of time thinking about aesthetics
or beauty, but sometimes, he noticed the raw beauty in the people around him.
It happened more and more with Shinsou, and Aizawa sometimes found himself
wanting to capture the moment. He wasn’t the biggest fan of posed pictures,
though he dealt with them when Shinsou really wanted him to, but he found that
there was something different when the pictures were candid and unposed.
The first time it happened, Shinsou was being his normal self. It was the first
winter he was spending with Aizawa, the first winter since they’d started
whatever this was and he’d had Shinsou move in with him, taking him out of a
bad home situation. As always, Shinsou was being respectful of the quiet Aizawa
needed when he graded essays, having taken to curling up on one end of the
couch with his phone in hand, a blanket half draped over his lap. Behind the
couch in the apartment were large windows that Aizawa didn’t usually draw the
curtains around. Today was no different, and when Aizawa looked up from his
work from where he sat on the floor, he stared at the way the setting sun shone
colors of reds and pinks and oranges across the kid’s pale skin and violet
hair.
Shinsou didn’t take any notice, eyes moving as he read something on his phone.
He was sitting partially slouched over, leaning against the pillows on the end
of the couch, feet tucked under his body. He looked content, expression relaxed
and void of any sort of stress or unhappiness, and he looked genuinely
interested in whatever he was reading, resting his cheek against his hand and
leaning on the arm of the couch. Aizawa let himself look, taking in the way the
sky’s colors drew across his skin and made him glow, the way it turned his hair
different hues, the way it just made him look that much more relaxed.
Maybe Aizawa wasn’t the most outwardly sentimental man and maybe he wouldn’t
admit to anyone except himself that he probably was in love with this kid and
far more than he should be as just his parent, or whatever he was, but Aizawa
did want to save this. He didn’t want to stop looking at it, knowing that the
moment would pass in some way or another. Either Shinsou would look up,
probably ask if he was done for the night, or the sun would set. So Aizawa did
the logical thing, pulled out his phone, and lined up a photo, being careful to
not make too much noise. He snapped it quickly, tucking his phone back against
his side, and hesitated before getting up.
That drew Shinsou’s attention and he looked up from his phone at hearing Aizawa
rousing himself from his place on the floor. The kid smiled at him, raising an
eyebrow curiously, “Are you done working?”
“For now,” Aizawa told him, going over to the couch and pulling the curtains
from the sides of the windows lining the wall of the room, having to reach over
Shinsou and the back of the couch to pull them over the windows. He pulled
back, flipping on the light, giving Shinsou a glance as he did so, “You really
shouldn’t read in the darkness. It’s bad for your eyes. You don’t want to have
to wear reading glasses like me, do you?”
“I think you look good in them.”
“That wasn’t what I asked,” Aizawa stood back up, not daring to look back at
the stack of papers still waiting to be graded. Frankly, he was tired of
looking at them, tired of sitting in silence, and tired of having to read the
same less than average essays over and over. He’d held off for a few hours, but
now that he’d gotten up and teased himself with the prospect of interacting
with Shinsou instead of grading, he didn’t have any intentions of going back to
it. He breathed a sigh, giving up on trying to get himself to work more, and
sat on the couch, next to Shinsou, originally with a little space between them
until Shinsou almost immediately put his phone down and crawled to him, Aizawa
apparently being more interesting than whatever he’d been doing.
He didn’t try to fight it, instead giving in even further and opening his arms
to Shinsou. Shinsou didn’t even pause, climbing onto Aizawa’s lap and slipping
his thin arms around him with what Aizawa thought was a small laugh.
He thought about telling Shinsou, letting him know that Aizawa had taken a
photo of him, but he decided against it, figuring that if it happened again,
he’d tell him at some point.
Part of him wondered if Shinsou ever took pictures of him. He only assumed so.
 
The second time it happened wasn’t long after. It happened the next day. It was
as if he hadn’t truly realized that he could take candid photos of the kid
until he actually did so, and after that, whenever Aizawa noticed Shinsou not
paying attention, he’d be reminded of the photo on his phone.
It wasn’t really a question of if he wanted to or not. It was if he could get
away with it. Shinsou had something about him, something that seemed to attract
Aizawa in a way that he hadn’t liked at all when he’d first met him, though it
was something he’d accepted more and more as they’d started this half parental-
half relationship sort of thing they had. For now, he really just wanted to
keep it private. It wasn’t that he thought he was doing something wrong, given
that the photos he’d taken were completely innocent, it was more just that he
wanted to keep this for himself for now.
The second time it happened was unremarkable and similar to the first. Aizawa
happened to notice Shinsou at a time when he didn’t notice Aizawa, a time when
he’d been watching some movie on the television in the apartment, and had
gotten a quick photo of him.
The third time, however, was remarkable, because Aizawa made the mistake of
doing it in front of someone.
It was nothing out of the ordinary—he and Shinsou often went to dinner with one
Yamada Hizashi, a man Aizawa had been involved with since high school and
someone with whom he had an open relationship. Hizashi was, thankfully,
completely aware of Aizawa’s odd relationship with Shinsou, and though he was
initially a bit put off by it, he was fine and accepting of it now. His only
complaint was that he wished often that Shinsou and Aizawa would come home more
often, instead of staying in the on-campus apartment that Aizawa lived in
during most of the schoolyear in order to keep his classes safe.
Shinsou tagged along with Aizawa often when he went out with Hizashi, mostly
because Hizashi liked the kid a lot, too, given that he was also his parent.
Today was no exception, and tonight they’d decided to go out to a hibachi
restaurant. Hizashi was in the middle of a story—something one of his fellow
English teachers had done at the school—and Aizawa had genuinely been paying
attention, before he’d looked across the table to see Shinsou leaning forward
as he listened to Hizashi, smiling slightly and nodding his head every now and
again, clearly very much into what Hizashi had to say.
Aizawa was a little taken aback by it. Hizashi and Shinsou could talk together
for hours and never quite get boring, and this wasn’t the first time Aizawa had
seen Shinsou get into listening to a story. But, as the low lighting of the
restaurant shone down on him and his face was illuminated by the flame of the
grill on the table between them, Aizawa found himself staring.
He thought about it for a moment, wondering if he could get a photo without
Shinsou noticing. The kid looked too interested in what Hizashi had to say to
notice him, and Aizawa tested it out by reaching into his jacket for his phone,
watching as Shinsou continued grinning at Hizashi, never taking his eyes off of
him. He tried to be subtle about it, and Aizawa rested his phone on the table,
managing to angle it and line it up enough, taking a photo before pushing his
phone back into his jacket.
That was when he realized that he’d been caught, because even if Shinsou didn’t
look away from Hizashi, Hizashi himself glanced at him for a split second and
raised an eyebrow, never stopping his story or raising the suspicions from
Shinsou across the table. But Aizawa knew. And he knew that Hizashi knew.
He didn’t waste any time when he got his chance later, making sure Shinsou had
walked out of earshot while getting up to go to the bathroom before he turned
to Hizashi and near-whispered his defense.
“I was just taking a photo.”
“Hey,” Hizashi put his hands up in a surrender, as if Aizawa had just accused
him of something terrible. “I didn’t say anything! Come on, Shouta, don’t act
so ashamed. It’s kind of cute, actually.”
“It’s not like I don’t have any of you on here,” Aizawa looked away, taking a
needed drink of the alcohol he’d ordered, feeling the burn of it on his lips.
“Aw, you take photos of me, too? Cute.”
“Stop that,” Aizawa frowned, his face burning like he was in high school again.
“Don’t tell him.”
“Alright, alright,” Hizashi conceded, putting a hand on Aizawa’s shoulder. “It
is cute, though.”
 
It kept happening after that, as if the one person finding out and giving him
positive reinforcement about it had spurred him to do it more. It was always
just of Shinsou, though. Aizawa wasn’t particularly fond of photos of himself
and he didn’t particularly enjoy having his photo taken. He’d put up with it if
Shinsou really wanted a photo with him, which he had a few times, just because
he knew that that sort of thing was important to him, but besides that, Aizawa
only ever wanted photos of other people, usually preferring the unposed ones.
There was always exceptions to rules, though, and Shinsou seemed to be the
exception to all his. He’d been the exception to the not getting to attached to
students rule, as well as the not being attracted or falling in love with them
rule. Regardless, whenever Aizawa found an exception to something that he
personally didn’t do, it almost always had something to do with Shinsou.
When he found the exception to the not taking photos of himself rule, it also
centered around Shinsou.
It was a calm night, and Aizawa was more than exhausted, mostly since the
stress of the end of the semester was over and the lost sleep was catching up
to him. When he’d suggested that he wanted to go to bed—or at least lay
down—earlier than he usually did, Shinsou was quick to join him, and Aizawa
realized that the stress from the end of the school semester was probably
catching up to him, too.
Showering together had woken Aizawa up a little, and afterwards, he’d assumed
Shinsou was going to fall right asleep, though it was an admittedly pleasant
surprise when he didn’t.
That was how he wound up lying in bed, Shinsou cuddled against his side, deep
into telling him about some incident with that petty kid from 1-B. He’d been
trying to read in an attempt to make himself tired again, but he wasn’t
disappointed when Shinsou had started talking to him.
“—Anyways, that little fucker—”
“Language,” Aizawa gently reminded him, having to force himself to keep the
amusement out of his voice. Shinsou was good at minding his manners for the
most part, and Aizawa never had to tell him to watch his tongue even when
Shinsou let loose around him, though the kid did have a habit of cursing a lot,
something he assumed that he’d gotten from where he’d lived before this.
“Right,” Shinsou frowned, as if trying to figure out how to rephrase what he’d
been saying, looking like he was concentrating hard on it. “So that little
shi—that kid got the rest of his little friends—I don’t even know how he has
friends, he’s so insufferable—”
Suddenly, Shinsou’s face fell, and he stopped talking. Aizawa was about to
question him when Shinsou glanced away from him, voice quiet and all the
excitement falling out of it when he talked.
“—Sorry, I know you’re trying to read.”
Aizawa stared at him, seeing that Shinsou was genuine. This happened sometimes,
still, with Shinsou being nervous around him or worrying about annoying him. He
was a good kid, honestly, and Aizawa never found himself being irritated with
him. It wasn’t like he wasn’t annoyed occasionally with other kids—his class
could be a testament to that—but things with Shinsou were a little… different,
in more ways than one. The kid listened to him well and usually picked up
pretty well on if Aizawa wasn’t up for talking. Aizawa was actually genuinely
interested in what he had to say, as well. He didn’t know if it was the fact
that their personalities were similar or just that Aizawa had spent so much
time with him that he’d started making subconscious changes and compromises, or
just a combination of the two, but Shinsou was a good kid and Aizawa hadn’t
ever really felt irritated or annoyed with him like he had with most of his
class.
At the beginning of all this, Shinsou had been far more nervous. It had really
started when he’d moved in and then started to die off when Aizawa had made it
clear that he’d say something if he ever way annoyed and wanted him to be
quiet. Whatever anxiety still remained, though, sometimes showed its face.
“You’re more interesting than my book,” Aizawa told him, holding Shinsou’s gaze
until the boy ducked away, half hiding his face in Aizawa’s side. He was
pressed up close to him, Aizawa lying on his back, his book long since put down
on his chest. He had an arm around Shinsou, wrapped under him and around his
shoulders, and Shinsou had an arm thrown over his chest, his body and head
tucked into Aizawa’s side and close enough that he could feel every breath the
kid took against him. He continued to stare at him, even as Shinsou hid his
eyes from him, “Keep going. Don’t stop in the middle of a story.”
“Really?” Shinsou’s voice was quiet, still, but higher pitched with surprise.
He cleared his throat, voice dropping back into a normal tone and volume.
“Alright, well, so that Monoma ass—that Monoma kid  got a bunch of his
friends—they were really more of accomplices—and he started saying that he
wanted to see if he could copy my quirk. That’s really stupid and lame, you
know? There’s no reason why he wouldn’tbe able to, so I knew they were just
trying to rile me up…”
He listened to Shinsou’s story, not saying much other than an occasional
comment. It relaxed him more than reading had, and at some point, he leaned his
head back against the headboard of the bed and half closed his eyes, trying to
stay awake so Shinsou could at least finish talking to him. It was easy to
notice Shinsou getting tired, too, his speech getting slower and thoughts
getting more scattered until he was struggling for words by the end of it,
looking like he was about to fall asleep at any time. He finished up
eventually, Aizawa also feeling like he was about to drift off, ending on
another amusing rant about how much he disliked the kid from the other class.
By the end, Shinsou had his eyes shut and when he fell silent, Aizawa knew it
was time.
He tried to get himself to reach for the light on the table beside the bed, but
something stopped him. Shinsou was even more pressed against him than before,
his head resting on Aizawa’s chest and his fingers gripping onto the loose
shirt Aizawa had worn to bed. Aizawa had a bad habit of watching Shinsou while
he slept, a habit born out of his own inability to properly sleep through the
night, and that was what made him stare.
Deep down, Aizawa was an affectionate person. He wasn’t affectionate with many
people, usually refusing to be touched by others, but with a select few, he
liked being touched. Shinsou had become one of those people and now, lying in
bed with him, holding him against his side, Shinsou’s head on his chest with
his mouth partially open as he breathed evenly, there was nowhere else Aizawa
wanted to be, and he wouldn’t give this up for the world.
He wanted to keep this moment, and that was what spurred him to break his rule
of never taking photos of himself.
In part, it was the way Shinsou looked—at peace, innocent and happy curled
against him. He’d usually wear one of Aizawa’s shirts to bed and today was no
different. Somewhere under the covers, he could feel the unmistakable lump of
the cat plush Aizawa had offhandedly given him months ago, something that
Shinsou never slept without and was pressed between them somewhere against
Aizawa’s thigh. He liked seeing him anytime, but there was something oddly
intimate about seeing him sleep and something oddly comforting about seeing him
at peace.  
And—he wanted to keep that. So he moved carefully so as not to stir Shinsou,
taking the book off of his own chest and fumbling for his phone on the
nightstand. It was a bit of a challenge, given that he was only using one hand,
but he managed to turn on the front camera and hold his phone up, angling it so
that he didn’t get much of himself in the shot.
He wound up being unable to cut at least part of his face out, ending up
getting his unshaven chin and mouth in the photo, but he was able to get all of
what he wanted of Shinsou in there, and that was what mattered. He took the
photo, hesitated, and didn’t let himself think about it as he quickly set it as
his phone background. It really was time for bed, then, and Aizawa set his
phone back on the nightstand, reaching out to shut off the light, freezing up a
little when he felt Shinsou move a little against him.
“What was that…?” Shinsou’s words were mumbled and jumbled together and it took
Aizawa a moment to figure out that he’d actually said something and not just a
groan of impatience at Aizawa taking too long to turn off the light.
“Nothing,” Aizawa answered him, sinking down as he turned off the light and
flooded the room with darkness. He leaned in, hoping that he could get Shinsou
to leave the topic, brushing his lips against the kid’s head and then against
his mouth. He didn’t linger, muttering out another response before relaxing and
laying his head against the pillows, “Don’t worry about it.”
“Ow,” Shinsou complained. “You need to shave.”
“I will in the morning.”
Shinsou seemed happy with that, and Aizawa was just glad that he’d gotten away
with another photo, though he wasn’t sure how he was going to hide it from him
now that he’d made it the background on his phone.
 
It didn’t even take a day for others to notice. Luckily, it was just Hizashi,
because Hizashi was really the only person he let get close enough to him that
he’d ever see his phone background, but nevertheless, he noticed almost
immediately. He’d leaned over Aizawa’s shoulder when he’d been going through
his email, and had unintentionally seen the photo he’d used on his phone.
“Oh, cute,” Hizashi commented quietly, cooing at Aizawa, pulling him closer to
his side. Aizawa just groaned, not putting up a fight, and Hizashi’s voice
dropped a little lower, “You gotta be careful, though, Shouta.”
“It’s nothing inappropriate,” Aizawa told him, not looking up from the email he
was reading. “Everyone here knows that I’ve taken him in, anyways.”
“Just be careful,” Hizashi sang at him, still being uncharacteristically quiet.
“It’s cute, but be careful who sees it. And if you do take any inappropriate
photos… well, just be careful to save them where no one else will see them.”
With that, Hizashi separated from him, laughing at the shocked look Aizawa gave
him before sitting down at the desk next to Aizawa’s. Aizawa frowned, glaring
at him, wanting to say that he wouldn’t do that, that that was completely
ridiculous and irrational to even suggest, but the words wouldn’t come.  
After all, he’d thought about it, and he’d thought about it more than he’d ever
admit to anyone. And unfortunately, he knew that Hizashi mentioning it was just
a slippery slope to doing it.
 
Aizawa managed to hold out for about a week.
He’d be lying if he said he wasn’t tempted, though. Shinsou was a teenager
going through the height of puberty, with near constant access to the person he
was in some sort of relationship with, and Aizawa… Well, Aizawa wasn’t some
horny teenager, but Shinsou got him worked up more than he’d like to admit,
given that he was thirty years old and thought that he had more control. It
didn’t help that Shinsou was willing to do anything, and it really didn’t help
that Shinsou was naturally sexually submissive and even more so to Aizawa.
Aizawa wound up having him in his bed (or the couch, the counter, the shower,
the floor—really, anywhere he felt like it) nearly every night in some way or
another. Shinsou was more than happy with anything, and Aizawa liked to please.
Aizawa was fairly dominating in bed—sometimes with Hizashi just almost always
with Shinsou. It wasn’t always the type of dominating where he’d tie Shinsou
down and make him beg, but Aizawa always had control in some way, and with
Shinsou, that was the way he wanted it. Shinsou was submissive, anyways, so
everything worked out.
In fact, it worked out a little too well, and Aizawa found himself a little too
comfortable with it.
Some nights he got rougher than others. Sometimes he was more stressed out and
needed a release. Sometimes Shinsou asked for it. Sometimes things just led
that way. Tonight things had just led that way. Aizawa was careful to never
actually hurt Shinsou, and the kid had words he could use to make him stop, but
the fact that Shinsou really, really seemed to like it when Aizawa got rough
and would hold him down didn’t make him want to go any softer on him.
Tonight in particular had gone down a rougher path. He didn’t exactly know how
it’d started, though it was pretty hard to think about anything with Shinsou’s
lips wrapped around him, but he was fairly sure it’d had something to do with
some snarky comment Shinsou had made at him in bed, clearly with the intentions
to spur Aizawa into being harder on him. He usually went along with what
Shinsou wanted, because the kid usually had good ideas, and it’d ended up with
Aizawa pinning Shinsou against the mattress, thighs on either side of his head,
pinning him by the shoulders, and his dick between Shinsou’s pretty lips.
It was dark, Aizawa having planned to go to bed before Shinsou had initiated
this, but he could still see Shinsou’s face well, and like every other time, he
admired the way he looked right now. Shinsou took cock exceptionally well,
always looking good doing it, whether he was happily sucking him off or begging
for him as he fucked him. He was always so enthusiastic, even now when Aizawa
had him pinned down and wasn’t letting him move much.
He stared down at him, one hand threaded through Shinsou’s wild hair, and
pulled back so that only the head of his cock remained between his swollen
lips, watching as Shinsou’s violet eyes fluttered open and he looked up at
Aizawa with hooded eyes, batting them at him in an almost teasing way and he
twisted his tongue over his head, drooling slightly on himself.
So enthusiastic…
Shinsou wasn’t even undressed. He was still in the shirt—Aizawa’sshirt—that
he’d gone to bed in, still wearing the too-big sweatpants, even though he knew
that the kid was desperate to get off. He’d just readily accepted Aizawa
pushing him around, and even more readily accepted when Aizawa had held him
down and told him to suck his cock.
“Hitoshi—” He was good at it, too. Good enough that Aizawa was barely holding
onto his composure. He pushed himself back into that waiting, warm mouth,
Shinsou giving a choked noise of appreciate as he did. He stroked Shinsou’s
hair, swallowing the groan that threatened to burst from his throat, “—Good
boy.”
Shinsou seemed to glow at the praise, pushing his head forward enough that he
could bury his nose in the soft black curls at the base of Aizawa’s cock.
Aizawa breathed out shakily, fighting to control himself and hold on for a
little longer.
It was really hard when Shinsou got so into this, when he looked so pretty
sucking his cock.
His face was flushed, his eyes closed again. His lips were swollen from where
Aizawa had bitten at them earlier and from now, from how he had them stretched
around him. He was still drooling, not even trying to hide it or stop it, and
he’d give happy noises, little moans and sighs, whenever Aizawa would pick up
the pace and fuck his face.
It’d been in the back of his mind all week, but when Aizawa remembered
Hizashi’s words, his resolve almost entirely crumbled away. Shinsou’s eyes were
closed and as Aizawa started fucking his mouth again, he didn’t see any reason
to not take his picture like this.
 Really, Aizawa had every intention to take a photo of Shinsou with his cock in
the kid’s mouth. He’d grabbed his phone, hardly remembering how to pull up the
camera when he was this close to coming inside Shinsou’s mouth, and had started
to try to line up a photo. Shinsou apparently had other plans, though, even if
he never opened his eyes to see Aizawa pointing his phone’s camera at him. He
chose that moment to moan around Aizawa’s cock, to shift enough for Aizawa to
realize that he was struggling to touch himself and not being able to, and to
wrap his tongue around him in just the way he liked, all of it resulting in
Aizawa shoving himself as far into Shinsou’s mouth as he could, bracing his
arms against the sturdy headboard as he came down the kid’s throat with a low
groan.
He’d had every intention to take that photo, but that wasn’t the one he got.
The one he got was much better.
He pulled out of Shinsou’s mouth, sitting back on him and being careful to not
put all his weight onto the kid’s chest. He was breathing heavily, and so was
Shinsou, and he gently ran a hand through his hair, his voice quiet between his
breaths, “Are you alright?”
Shinsou nodded, half-opening his eyes at him, lips turning upwards into a
smile, “Was I good, Sensei?”
He had this terrible way of managing to make Aizawa want to go another round,
even when he was exhausted from the first one.
“Yes,” He knew what Shinsou wanted, and he couldn’t blame the kid. Shinsou
sighed happily when Aizawa reached back, hand slipping under the waistband of
his pants to find that Shinsou’s dripping cock had already wet a good portion
of his underwear. He didn’t hesitate, giving Shinsou his reward for being so
good and eager, fully planning on getting him off and going to sleep and trying
to get his photo next time.
That plan was changed the moment Aizawa looked back at Hitoshi’s face.
He’d closed his eyes again, lips parted as he smiled and cooed as Aizawa
stroked him. He was still holding him down, and the collar of the shirt he was
wearing was wet with drool and the small amount of cum that had spilled from
his mouth. There was a small spot of it on his lips, too, his face still red
and hair still splayed over his forehead and the pillow. He looked perfect—and
Aizawa still had his phone in the hand that wasn’t getting him off.
It didn’t take a lot of thought. Aizawa got his picture and a few moments
later, Shinsou came in his hand with a strangled cry of his name.
He cleaned them both up, wiping at Shinsou’s mouth and face to make sure he’d
gotten everything. Shinsou was already asleep by the time Aizawa made it back
to bed, giving him a few moments to look at the photo.
It almost looked innocent. Aizawa’s thighs holding him down almost blended in
with the darkness of the edges of the photo, only noticeable if someone was
really looking. He could see the cum on Shinsou’s lips and his shirt, but it
easily could’ve been any substance. It was a good photo, and he followed
Hizashi’s advice, making a new folder on his phone and moving it in there,
knowing he was going to regret having to move and sort photos into there later.
 
It took Shinsou a little while longer to finally notice, and when he did, it
was when Aizawa was fucking him.
It was really Aizawa’s fault. He’d gotten a little too comfortable taking
photos of Shinsou, whether in sexual situations or not and he’d started getting
more than a little clumsy while doing it. He still had the background of
Shinsou asleep with him on his phone and he still hadn’t noticed, even though
it’d been a couple weeks. Maybe Aizawa was pushing it, but it was on a night
when Aizawa had the energy to fuck him that he actually messed up.
The night fell on one of the last few days of the kids’ break, and Shinsou
apparently knew that he could be as loud as he wanted to be, given that no one
was around to hear him, and he took advantage of that. Aizawa had a soft spot
for his voice, as he’d found out, and though he’d been his usual tired, lazy
self for the day, hearing Shinsou be so vocal had given him the push to
actually fuck him.
It wasn’t a new thing—Aizawa was just older and didn’t have the energy for it a
lot of the time. It took a lot out of him, and Shinsou seemed happy with doing
everything else on a regular basis. Having the chance to fuck him as loudly as
he wanted to wasn’t something that came around often, though, and Aizawa wasn’t
about to waste the few chances he got for it.
No one was around, so Aizawa tied Shinsou’s hands to the headboard and teased
him until he was begging and nearly screaming in frustration at him. He’d
teased him even more with slowly preparing him, telling Shinsou that he was
just making sure he wasn’t going to hurt him, and the boy nearly cried with
relief the moment Aizawa finally gave in and pushed inside of him.
Shinsou wasn’t quiet about it at all after that and neither was Aizawa. He
couldn’t be when he was buried inside Shinsou’s tight ass, the kid so strung
out and turned on that all he could do was moan and yell unintelligibly, the
only thing Aizawa being able to understand being his own name.
He didn’t hold back, fucking him hard. Shinsou’s arms were above his head, not
letting him touch himself or Aizawa, but the way he’d tied him allowed Aizawa
to move him around or reposition him as much as he liked. He took advantage of
that, as well, eventually moving Shinsou so he was more on his side, pushing
his leg up into the air and mouthing at his neck as he fucked him from this new
angle.
He was about ready to move Shinsou around again, partially to give him more
chances to experience new positions and partially to hold off his own orgasm,
when he bit down above Shinsou’s collarbone, tilting his head up to look at the
boy, finding Shinsou looking more fucked-out and more beautiful than Aizawa had
ever seen him before.
He hauled himself up, thrusts shallowing, leaning over Shinsou with his hands
on either side of him, breathing hard as he pushed himself into his tight, hot
hole, Shinsou calling out again as he did, mouth stretched wide in an
unintelligible plea, eyes just barely open as he looked up at Aizawa. He was
completely red, all the way from his face to his erect cock, bouncing with
every thrust into him. He’d drooled on himself again, bare chest wet with his
own spit, chest, stomach, and thighs all littered with various bite marks from
today and bruises from previous days. Aizawa didn’t even realize how much he’d
marked the kid until then, nor had he realized how much he’d teased Shinsou.
He was pretty sure that if he even touched Shinsou’s cock, he’d come in an
instant.
To his surprise, Shinsou pulled out of his fucked-out daze the second Aizawa
pulled out of him, “H—hey, where the hell are you going—?!”
Aizawa hadn’t even managed to move very far before Shinsou was looking at him
with panicked, lust-filled eyes. Aizawa frowned at him, having made a decision
when he’d seen Shinsou’s face, and slowly found his own words again, “Don’t
worry. And don’t move.”
Shinsou followed his directions, staying in the position that Aizawa had put
him in, still keeping his legs spread even though it was no doubt uncomfortable
without Aizawa there to support him and hold him up. He retrieved his phone
from the floor, where it’d fallen at some point, probably from the bed shaking,
and then resumed his previous position, not saying or explaining anything, only
going back to Shinsou and grabbing his hips again, cutting Shinsou off as he
pushed into him again.
“What are you—” His voice tapered off into a long moan and in the moment, he
seemed to forget about what Aizawa had done and why he’d momentarily stopped.
Aizawa didn’t hold back long, though, and that was his mistake. He didn’t even
check to make sure that Shinsou had his eyes shut, only noticing when the boy
cried out that he didn’t and by then, Aizawa had already taken the picture.
He took it on a particularly harsh thrust, Shinsou yelling out again, and he
bottomed out inside of him, getting a photo of Shinsou’s flushed, marked body
and his fucked-out face.
“Did you take a picture of me?!”
That was when he realized his mistake. He tossed his phone back on the bed,
cursing at himself under his breath. Shinsou didn’t say anything more, though
Aizawa didn’t think he was able to, given that Aizawa had picked up the pace,
fucking him fast and wrapping a hand around his dripping cock in an attempt to
get him to forget about what he’d seen.
It worked, in the moment, Shinsou’s voice turning into a desperate plea as he
arched his back, his wals tightening around Aizawa, “Sensei, please—”
 
He didn’t honestly think Shinsou forgot about it. Shinsou had a notoriously
good memory and while distracting him had worked in the moment, Aizawa knew he
was in for a questioning as soon as Shinsou remembered in the morning. He’d
fucked him too hard for Shinsou to be any bit coherent after Aizawa had finally
been done, finishing a few times inside of him, and he was thankful that he
could at least put it off until morning.
He didn’t think, though, that he’d be awoken at—he rolled over to check—six in
the goddamn morning for that round of questioning.
“Hitoshi, it’s too early for this.”
Shinsou was hovering over him, dressed in only one of Aizawa’s shirts, hands
still on his shoulders from where he’d shaken Aizawa awake. Aizawa tried to
reach out and wrap an arm around Shinsou’s neck or the back of his head,
intending to pull him back down into his chest so he could go back to sleep and
put this off for a few more hours, but Shinsou ducked out of his way, moving so
that Aizawa couldn’t pull him back down.
“If you tell me, I’ll go back to bed,” Surprisingly, he didn’t sound angry,
instead grinning at Aizawa with the smirk that told him he was up to something,
that something being a bribe for information. “Did you take pictures last
night?”
“Yes, I took pictures,” Aizawa muttered, instead grabbing Shinsou’s arm and
trying to pull him down. He dodged that, too, pulling away before Aizawa could
get to him. The exhaustion lingering in his body was making him slow and it was
probably a bad idea to try this with someone he was training to be faster and
more agile. He stared up at the kid, raising an eyebrow, “Are you upset about
it?”
“No!” The insistence was immediate. “I want to see.”
Conceding, Aizawa rolled over and picked his phone off of the nightstand. He
didn’t show him as soon as he did, instead pausing, “I’ve been taking photos of
you for months. Do you want to see those, too?”
He was serious, and Shinsou just stared at him for a long moment.
“Really?” He asked, voice quieter, more emotional. “I didn’t think you liked
taking pictures. Are they all of you having sex with me?”
“No, most of them are innocent,” It was the truth—the majority of his photos
were innocent ones of Shinsou at home with him. The sexual ones were a very
small number compared to the others. He unlocked his phone, angling it so
Shinsou could see the photo of him asleep on Aizawa, “I can’t believe you
didn’t notice. You should really be more observant.”
“Don’t turn this into a lecture,” Shinsou pouted at him, but settled into his
side, wrapping an arm around Aizawa’s chest, “I want to see the rest.”
With that, Aizawa gave up any hope of getting back to sleep. It wasn’t that
disappointing, though, given that he got to spend the next hour showing a very
excited Shinsou all the photos he’d taken of him. Honestly, his excitement was
worth losing the sleep, and Shinsou let him pull him back against his chest at
the end of it, anyways, Aizawa getting a few more hours of lazy sleep in
afterwards.
