****** Storage Room Fun ******
by saucyseal
Summary
     When Toshi and Izuku try to get a little frisky in a storage room at
     school, they are interrupted by Aizawa. He becomes an added person to
     their escapade.
Notes
     This is a super self-indulgent fic I started to write when I saw the
     first few episode of BNHA, so excuse me if the characters aren't
     totally in character per the rest of the series.
Aizawa just wanted to sleep.
His annoying little students weren’t shutting up about getting into Yuuei and
passing his test. He called it quits and gave them a study period so he could
go and take a nap. His usual place was a storage room that nobody came in
except for him or All Might. Both of them keeping it a secret so other teachers
or, god forbid, students tried using it for various reasons.
He had just settled in his sleeping bag behind a desk and cabinet, tucked away
in a dark corner, when he heard footsteps stop outside the door. It clicked
open and he heard shuffling inside. He was about to get up to tell All-Might to
get the fuck out so he could sleep when he heard high pitched moaning. Aizawa
leaned up, peeking around the cabinet, to see the skinny All-Might and his
student, Izuku Midoriya, kissing passionately. All-Might had his lips suckling
on the corner of Izuku’s neck and shoulder, causing another loud moan to escape
the green-haired boy’s mouth.
“Izuku, if you don’t want anyone to interrupt us, you have to stay quiet,
yeah?”
Whining and panting, Izuku looked up to his mentor, “But… you make it feel too
good, All Might.”
“Izuku, what did I tell you to call me when we’re alone like this?”
Izuku looked down, avoiding All-Might’s gaze, his face bright red. “T-t…Toshi?”
All-Might gave him a gentle kiss on the top of his head, “Don’t be shy, Izuku.
It’s just me and you here.”
Aizawa silently snickered at that comment, knowing just how wrong he was. He
was about to get up, to stop seeing what he REALLY shouldn’t be seeing, when he
heard a zipper being undone.
“I-Izuku? Are you sure you want to do-haah-that here?” moaned All-Might as
Izuku unzipped his mentor’s pants and drew out a half-hard cock from its
confines.
“I couldn’t wait, Toshi. Seeing you all dressed up, being accepted to this
school, I couldn’t wait till we got home.”
“Izu- oooh god,” All-Might’s retort cut off as Izuku took the head of All-
Might’s long cock into his small mouth.
Aizawa’s eyes opening wide, shocked to see what teacher and student were doing.
He was stuck, should he interrupt them now and leave? Should he let them leave
after they were finished? But how far were they planning on going? How long
could he sit there, ignoring the growing throbbing in his pants?
He decided he needed to get the hell out of there, he would feel way to pervy
if he stayed, or even caught. He shuffled out of his sleeping bag, stood up,
and exited the safety of the cabinet. He cleared his throat and watched as All-
Might’s eyes focused on the extra person in the room. Izuku stood up and
swiveled around to stare at his teacher in horror, lips puffy and pink from
what he was just doing.
“Ai-Aizawa, what- what-uh-are you doing here?” uttered a shocked All-Might.
“I WAS trying to catch up on sleep away from my annoying students, but,” he
turned to stare at Izuku, “it looks like one of my annoying students is still
bothering me.”
Izuku couldn’t possibly turn a shade redder than he already was as Aizawa gave
him a heavy stare.
“Ah well, I didn’t see you on the couch, so I-uh-assumed you were sleeping
somewhere else,” All-Might shyly said.
“It was too bright so I settled behind the cabinet,” Aizawa explained as he
turned towards the door, “And now I’ll take my leave. I won’t tell anyone what
I saw, but next time, keep to doing this kind of thing at home.”
“Uh, Aizawa-sensei?”
He turned towards the small, green-haired boy, “What is it, Midoriya?”
“Um, you-uh- you shouldn’t leave with-uh-THAT in your pants,” Izuku meekly
said, as he pointed a shaking hand to Aizawa’s pelvic region.
Aizawa looked down and saw his erection still hadn’t settled down. “Tch,
annoying.”
All-Might chuckled at his reaction, clamping a hand on Izuku’s shoulder, “So
you liked Izuku’s little show that much, huh, Aizawa?”
Izuku went a thousand shades of red, and whined at All-Might, “Toshi! Please
don’t say that!”
“It’s true though.”
Izuku looked up in shock at his teacher’s face.
Aizawa chuckled and grabbed the bulge in his pants, “I thought you looked
really hot on your knees, Izuku.”
Izuku gulped noticeably and looked down. He saw his own erection hadn’t gone
down, even after the embarrassment of being found by his teacher while he was
with Toshi. He clamped his own hands over it, stifling a groan at the contact.
“Izuku, did you like him watching us?” All-Might asked, seeing his little
Midoriya’s actions.
“Um, yeah, a little bit,” he answered softly.
“Then I propose a solution for everyone. How about Aizawa sits and watches us
while he gets rid of his erection and you and I can continue where we left
off?”
Izuku looked up into the earnest face of his mentor and lover and then at his
teacher before nodding in agreement.
Aizawa lowered his eyes in lust at Izuku, “I don’t mind the arrangement at
all.”
Aizawa turned and took two strides to sit on the couch, “So give me a show
then.”
Izuku looked up at his lover before reaching up, hooking his hand behind All-
Might’s head, and bringing him down for a passionate kiss. Panting, he fell to
his knees, face-to-face with All-Might’s erection. He dipped his tongue at the
slit, licking up the salty flow of pre-come. Then he swirled his tongue around
the swollen, red head of his cock, letting All-Might’s pants and moans fall on
his ears like music. Izuku turned his eyes toward Aizawa and saw he already had
his cock in hand, watching them with a lustful gaze.
Izuku slowly took in more of All-Might’s length, sliding his tongue along the
heavy veins wrapped around All-Might’s large cock.
“Ah, boy, you know just what I like don’t you, little Izuku?” All Might asked
as he gently caressed Izuku’s green hair.
Izuku swallowed his beloved mentor’s cock to the base, pubic hairs tickling his
nose, and he looked up with teary, lust-filled eyes into All-Might’s eyes.
Groaning, All-Might’s head turned up towards the ceiling as his face erupted
into flames, “My boy, that’s no fair! You look far too cute with your perfect
pink lips stretched around me!”
Renewed by the praise, Izuku bobbed up and down All-Might’s length, spit and
precome dripping out of the sides of his mouth.
Aizawa tightened his fist at the base of his own cock, quickly trying to stop
himself from coming too soon. He never realized just how attractive his young
student could be, how Izuku could be sexier than any man or woman he has ever
seen before. Izuku was truly too adorable with his unintentional
characteristics. Continuing to slide his hand slowly up and down, he
desperately wished it was Izuku’s mouth instead.
Izuku suckled a bit before letting the length pop out of his mouth. He shyly
continued to look up to his mentor and asked as sweetly as possible, “T-Toshi?
Can we please do more?”
All-Might groaned again before muttering, “you’re going to be the death of me,
I swear.”
But All-Might was never able to refuse his sweet boy anything, “take off all of
your clothing Izuku and give your senseis’ a little show.”
All-Might straightened his pants a little, with his cock still jutting out,
before walking a few feet to lean against the couch Aizawa was sitting on.
Midoriya faced his two senseis’ with a red face and started to undress in front
of their leering gazes. He undid his necktie, removed his school blazer, and
started to slowly unbutton his shirt. He carefully placed his school clothes on
a nearby table before kicking off his shoes. As he unbuckled and unbuttoned his
pants, he was interrupted.
“Oi, Midoriya, turn around as you bend to take off yours pants and underwear.”
Izuku burned red again at Aizawa-sensei’s request. All-Might slapped the back
of Aizawa’s head with a hissed, “Izuku doesn’t need to do anything he doesn’t
want to!”
The little green-haired boy quickly shook his head and blushed brightly as he
was able to stutter out, “it-it’s ok Toshi! I wa-want to make you both feel
good!”
Aizawa smirked at the slack-jawed All-Might before turning to stare at the
adorably blushed Midoriya. He gave his young student a hand flourish as to tell
him to continue with his stripping.
Izuku turned around before bending over as he pulled his pants down his butt
and legs. His little bubble-shaped behind was being squeezed in by All-Might
boxer briefs.
Aizawa leaned and whispered to the other hero, “like to show who owns that
tight ass, huh, All-Might?”
All-Might huffed in embarrassment and refused to answer the question.
After the pants came off and placed on the table, Izuku hooked his thumbs into
the waistband of his underwear. He bent over and slowly slid the fabric over
the swell of his cheeks and down his legs. He bent lower to pick the piece of
clothing off of the floor when he heard another request, this time in a much
breathier voice.
“Izuku, my boy, can you please stay bent over? Can you use your hands to spread
your cheeks and show us your pink, little rosebud?”
Izuku whined in embarrassment at the request his lovable Toshi asked but with
shaking hands he managed to achieve it.
Aizawa and All-Might gripped their hard lengths at the delicious sight before
them. Izuku flushed and bent over, his hands spreading the round globes of his
ass, and the twitching pink star settled between them.
All-Might broke the heavy, lusty breathing of the teachers, asking, “that’s
very good, my boy. Come here, it’s time I prepare you if you truly want to
proceed.”
Izuku shakily stood up and turned to face his hero. All-Might directed Izuku
onto his hands and knees, nearly inbetween Aizawa’s legs and facing his
teacher’s leaking member. Before he could ask a question about the position, he
felt All-Might’s big hands each grab a cheek of his ass and a large tongue
swipe over his entrance. His face turned from a surprised “o” into one of
complete and utter wrecked pleasure. One of Izuku’s weakness when it came to
sex was his absolute love of being eaten out.
As All-Might slurped away, tongue dipping into Izuku’s tight channel and broad
thumbs stretching the young boy’s tight entrance open, Aizawa got a full view
of how wrecked Izuku was becoming. A light sheen of sweat covered him, stray
hairs sticking to his face. His facial expressions excited Aizawa to no end.
The way the boy’s mouth hung open, tongue on the verge of hanging out and
saliva slipping down a side of his mouth. His eyes had a glaze of pleasure and
every time All-Might reached Izuku’s prostate, they would roll back in ecstasy.
With his arms and legs weak from pleasure, every time All-Might roughly tongue
fucked him, his shaky body would be nudged closer and closer between Aizawa’s
legs. Aizawa took full advantage to start stroking his cock fast in front of
Izuku’s flushed face. He couldn’t get enough of his student watching him fuck
his hand fast. He saw Izuku stare intensely at his cock and his pink tongue
swipe in hunger across his lips. He wanted more than anything to have those
lips wrapped around his cock but he wasn’t about to suffer the wrath of the
student’s lover, All-Might.
Aizawa and Izuku were so entranced with each other that they didn’t notice All-
Might pull up, planning to properly lube up his sweet boy. He smirked at
Aizawa’s face, seeing how focused he was on Izuku’s face, his open mouth, and
his heaving chest. Not so long ago, he was in the same position. Izuku tended
to have that influence in him, the power to bring down any person due to some
aspect of his person, be it his sensualness or his innocence.
With a quick inner debate, he decided to let Aizawa share his Izuku. Although
they would need to talk more in depth later, he slotted his hips behind Izuku’s
and draped his body over Izuku. Seemingly just noticing that Toshi’s tongue had
stopped pleasuring him, he blushed up at his lover, caught being entranced by
another man’s cock.
Before he could give an excuse, All-Might dropped a shocking offer.
“If my Izuku agrees, I give permission for you to use his mouth Aizawa.”
Aizawa took a pause from his frantic fist-fucking to gape at All-Might. All-
Might took the pause to lower a hand to Izuku’s mouth and push a finger inside.
As he pushed another finger inside the wet cavern, he casually said to Aizawa,
“no need to look so shocked. There couldn’t be a being on the planet that could
resist my little lover’s allure.”
Aizawa saw Izuku sloppily sucking on All-Might’s thick fingers, his cock
twitching at the sight of Izuku’s pleasure-hooded eyes.
He nodded, “if Izuku is more than willing, I’d love the chance to fuck his
mouth.”
Izuku blushed deeply and gazed to the floor as All-Might pulled his fingers out
of his mouth to loudly whisper into the boy’s ear, “well, Izuku? Would you be
interested in sucking Aizawa’s cock as I fuck your tight ass? Wouldn't you like
to know how it feels to be filled from both ends?”
Izuku was visibly affected by his mentor’s dirty words, trembling and panting
with arousal. His smaller dick pointing up and drooling, being neglected in his
haste to please his teachers.
But he nodded shyly to the pair of heroes and quietly voiced his opinion,
“yeah, yes, I want that so badly!”
Aizawa’s gaped mouth quickly turned into a feral smirk, “well, well, well,
isn’t that a sweet declaration. Suppose we should fulfil it, huh, All-Might?”
All-Might straightened his back and grabbed the lube from his inner coat
pocket, “suppose it does Aizawa.”
All-Might proceeded to wet his fingers and slowly add one and then two fingers
to Izuku’s entrance, which was still a little loose from his tongue-fucking.
Izuku moaned and leaned forward to lean his heated face to Aizawa’s knee.
Aizawa could feel Midoriya’s pants of pleasure puff against his cock and a
little jolt of arousal ran through him. He cautiously guided the shaft of his
cock closer to his student’s mouth until he could feel the silky lips of
Midoriya touching him.
Izuku whined at the strong smell of musky arousal coming from his teacher and
gently licked the underside of the member, a low groan of pleasure rumbling out
of Aizawa.
All-Might had slowly stretched his young lover to be able to take three of his
fingers spreading him open, giving him a glimpse of the hot, pink hole he would
be entering.
As Izuku gave Aizawa’s cock kitten licks over the sensitive mushroom tip, All-
Might got into position to enter him. He guided the enlarged head to the
stretched entrance and watched, enthralled, as the tip popped inside with
little resistance. The sweet, excited moan made him smile at the bobbing green-
haired head. He slowly slid the rest of the shaft in, until his hips fully
bracketed the hips of Izuku. Fully seated, he gave experimental grinds of his
hip, watching for any discomfort or pain. When he found none, he slowly pulled
out and in, increasing in speed.
Aizawa was in heaven as he watched his student swallow down the head of his
cock. Midoriya had the perfect cock-sucking lips, but what strengthened the act
was Midoriya’s tear stained green eyes focused on his face. He almost came at
the sight of Midoriya choking on his cock but there was no way he would cum
prematurely before All-Might. He swallowed down the need to cum as he ran his
fingers through his student’s sweaty hair and whispered little sentiments:
“You’re doing so well, Midoriya”
“Look at how well you’re swallowing me down”
“You feel so good Midoriya”
“The absolute best at sucking cock”
All-Might was pounding his lover’s ass without abandon. He could feel the soft
impact of Izuku’s cheeks against the V of his hips as he swiftly fucked him.
His hands gripped Izuku’s hips, not so rough as to bruise him, but enough to
keep him in place and feel a slight soreness in the next few days. The sound of
his young lover’s moans being choked back by the hard length down his throat
had shivers of pleasure going down his spine. Instead of inane jealousy running
through him at sharing his small boyfriend, he felt satisfied showing at least
one other person the pleasure that HIS boy could give.
Izuku couldn't believe the pleasure his body was in at the moment. He felt the
familiar fullness of his mentor and lover deep inside him, reaching every place
that gave him the utmost pleasure. The sensation of a cock deep in his throat
was a familiar one, but different with it being his teacher Aizawa’s cock
fucking his mouth. The main difference between the two heroes was the looks
they gave him as he sucked them in deeper. Toshi would give Izuku looks of
utmost adoration and love as he gave him a blowjob. But Aizawa… Aizawa looked
utterly hungry as he stared at Izuku working his cock in his mouth. The way his
mouth twisted in a dirty smirk and his eyes pulsing with raw want and lust sent
shivers down his spine. He realized he might like giving Aizawa-sensei a bj
almost as much as he did giving Toshi one.
Soon the pleasure of being spitted between the two men became too much and his
balls tightened up as he came from the pure pleasure he was receiving.
All-Might groaned as he felt Izuku tighten around his cock before his little
lover came untouched. He chased his own pleasure in the borderline painful
tightness before he slammed into Izuku as deep as he could and released his
cum.
Aizawa felt Izuku’s throat constrict around him as the student came without a
single touch to his cute, little cock. Watching Izuku’s bright green eyes roll
back in pleasure brought him closer to the edge and he thrust faster. He came
down Izuku’s throat with a low groan and pulled out of the tight, wet warmth
and squeezing the last of his release across Izuku’s face.
The trio all panted trying to capture their breath after their arduous activity
before Izuku slumped down to the floor, apparently boneless from the pleasure.
The two teachers grinned at each other, feeling prideful at pushing the young
man into such a pitiful state. All-Might was the first to move by grabbing a
handkerchief from his pocket and cleaning himself up before tucking his used
member into his pants. He cleaned Izuku of his cum before lifting him gently
from the floor and onto the couch next to Aizawa.
Izuku immediately seeked out comfort and warmth by curling himself into
Aizawa’s side, much to the teacher’s shock. Aizawa gaped at the young man and
looked up at All-Might in a slight panic, as if to say, “what do I do? Why is
he cuddling me? Why aren’t you taking him from me?!”
All-Might smiled at Aizawa’s mini freakout before settling his body on the
other side of Izuku and petting Izuku’s back.
“He likes to cuddle in comfort after having sex, it makes him relax from the
high he gets,” explained All-Might to Aizawa.
Aizawa nodded in understanding, his eyes softened as he gazed at Izuku’s
relaxed face and gently pet Midoriya’s hair (though he would vehemently deny
this when All-Might reminded him of his soft spot for the boy).
“How did you like having two, Izuku?,” All-Might asked.
Izuku cuddled his head deeper into Aizawa’s embrace, “ooh, Toshi, I loved it! I
loved Aizawa-sensei using me. It was so much different than when it is just you
and I, but I loved it just the same.”
Aizawa (blushed) made a harrumphing noise as he pointedly ignored them to tuck
himself back into his pants.
All-Might gave a booming laugh, “ah, well, Izuku, now I know who to leave you
with who can take care of you if I ever need to leave for something!”
Aizawa pet Izuku’s head before leaning the smaller boy into a sitting position.
“You’d want to do it with me again, Midoriya?”
Izuku blushed and slowly nodded his head yes, “only with Toshi’s permission,
he’s the one I’m in a relationship with after all!”
All-Might grinned, “it certainly would be fun to watch you two experiment
together!”
Aizawa (cheered) groaned in defeat, “fine, you get to use me as you wish,
Midoriya, per All-Might’s permission.”
Izuku leaned to All-Might, whispering a question into the taller man’s ear and
getting a “yes, you may” in response.
Confused, Aizawa waited to hear what they were agreeing to when he suddenly got
a lapful of Midoriya eagerly kissing him. Once the shock wore off, he eagerly
kissed the boy back, tasting himself on his tongue.
Taking a breath, he leaned back, “so is that a preview to what I get?”
Izuku gave him a lustful nod as All-Might lovingly looked at Izuku’s obvious
excitement.
Aizawa felt another shudder of excitement run through him as he thought of all
the future fun he was going to receive sharing the boy with All-Might.
