Summary
     “I bet you’re addicted, aren’t you,” Kuroo started, causing the
     spectator to grow curious – it was the only thing that could
     currently get his mind off the bulge in his pants. “It’s not just me
     anymore, is it? I bet you get around, letting anyone use you.”
Notes
     okay so my attempt at smut. it's terrible, but hey, practice? advice/
     cc would be cool, if you'd like.
     also wasn't quite sure if this should be rated M or E, so I did E
     just to be safe.
The final bell rang for the day, and man, was he beat. The students had truly
outdone themselves, tiring the PE teacher claiming he couldn’t do such-or-
other. Of course, the childish man took it upon himself to accomplish said
feats. Bokuto Koutarou never backed down from a challenge – it was a problem,
really. Wiping the sweat from his brow, the man fanned himself before setting
out to complete his task of putting away the equipment they had been using.
 
It was a good thing he had motivation, or else he would have stayed back for
another few hours. Snagging his phone from the bench, Bokuto set out to text
his good bro and the second year mathematics teacher, Kuroo Tetsurou. It was
short and sweet, and had even received a quick response that left him eager for
the beers they were supposed to drink afterwards. It was a great way to end the
day, if you asked him.
 
To:Kubroo
Gotta clean, b there when I can
 
To:Brokuto
Kool, meet @ 2-5, finishing up
 
Pocketing his phone, Bokuto went about the cleaning with a grin on his face. It
had been a while since he last winded down with his favourite colleague. It was
bound to be a blast.
 
===============================================================================
 
 
Nothing could have prepared him for this, absolutely nothing.
 
The door of the classroom had been slightly ajar, and Bokuto would have barged
inside if he didn’t hear that sound that made his face go red. He quickly
ducked out of sight, but his curiosity had been peaked. Sinking to the ground,
Bokuto peered through the crack and would have made an audible gasp had his
hand not been covering his mouth. There was something that told him that it
probably wouldn’t have been heard over that.
 
A loud smack resonated, large hands connecting to a pale, taut ass. A handprint
was sure to appear, had it not already. “Do you like that?” The larger male
sneered, and all the other could do was let pleasured moans spill out of him.
He couldn’t even nod if he wanted to, Kuroo’s hands fisting the short curls as
he pulled the student’s head backwards. His hand connected again, clearly not
pleased with the answer, “what was that? I couldn’t hear you.” The thrust of
his hips slowed to a halt, both hands steadying the other’s hips. He pulled out
nearly completely.
 
“Ple-please,” the other groaned, the lack of stimulation torturous as he tried
to push backwards onto Kuroo’s cock.
 
“’Hm?” The elder was clearly amused by the student’s desperation, if the smirk
on his face was anything to go by, “what was that, Akaashi? I won’t know what
to do unless you ask.”
 
The shorter male was about to reach between his legs for some form of relief,
though Kuroo was quick to swat his hands away. “Don’t,” he warned, causing the
other to gulp nervously.
 
Attempting to prop himself up on his elbows, Akaashi looked back at his
partner. He had a moment to compose himself (as much as he could for someone in
his position) before steadily demanding, “I need you to fuck me, Kuroo-sens-
ah!” A yelp of surprise cut his sentence short, the teacher pushing himself
back into the tight walls. The balance his elbows gave him failed as they
collapsed, Akaashi’s face now against the desk as Kuroo bent him over and
continued pounding into him.
 
The throes of pleasure were too much, especially with the teacher now brushing
a spot he had previously been avoiding. Akaashi didn’t have enough time to warn
him as he came onto the desk.
 
Kuroo grunted as walls clenched around him, fingers pressing hard on the
student’s hips. “Tch,” he seemed displeased, “what a slut.”
 
He pulled out almost immediately, not having reached his limit yet. He took off
the condom and tossed it, making a mental note to empty the bin later on. The
hands that were steadying Akaashi’s hips were removed, and the student whined
from the lack of proximity. He also ended up sliding to his knees, not enough
strength left in his legs.
 
“I bet you’re addicted, aren’t you,” Kuroo started, causing the spectator to
grow curious – it was the only thing that could currently get his mind off the
bulge in his pants. “It’s not just me anymore, is it? I bet you get around,
letting anyone use you” The lack of response seemed to irk the man, “turn and
face me when I talk to you, slut.” His tone of voice was harsh, and Bokuto had
half the mind to stop his colleague from potentially harming the student
further had Akaashi not turned obediently, dark green eyes darting between
Kuroo’s face and his member. “That’s better. Now get to work.”
 
It didn’t take more convincing for Akaashi to give Kuroo’s cock a few pumps
while he licked his balls, soon moving to leave a line of saliva as he traced
the base of his shaft to the tip. It didn’t take long before the head was in
his mouth, slowly taking Kuroo in, inch by inch.
 
Once at the base, the teacher reached down, tilting Akaashi’s head so that
they’d make eye contact. “Fuck, you look good,” he praised, and the student
seemed to drink up his words, “stretched around my cock like that.” His hands
went back to grip Akaashi’s hair, tugging just hard enough to make him gasp.
Kuroo took that moment to sheath himself in the teenager’s mouth completely.
Despite letting a grunt of pleasure escape his lips, Kuroo focused more on the
look of surprise on Akaashi’s face. Slipping out, he snapped his hips forwards
once again, and again, basking in the feeling of the boy’s throat spasms around
his dick. The tears prickling at the younger’s eyes were a huge bonus, too.
 
He would have continued until completion had he not noticed the hand moving
behind Akaashi, no doubt stretching himself wide open. It was a sight that made
Bokuto’s resolve fail, hand slipping to his crotch to palm himself through his
track pants.
 
“Oho? What’s this?” There was a wicked grin on his features as he pulled
Akaashi off of him, “getting turned on by sucking me off?”
 
He only received a whimper as a response, eyes catching each other once more.
 
Kuroo pulled Akaashi up and his fingers out of him, moving to the other side of
the desk so he could take a seat. He grabbed a foil package and bottle of lube
from his drawer, handing the latter object to the boy. “Go on,” he was met with
a questioning look as Kuroo urged on, “show me how you’re going to open
yourself up for me.”
 
It took the teen no time before he opened the cap, lathering his fingers with
the lubricant before starting off with two fingers, scissoring them as he
enjoyed the stretch. Kuroo’s never faltering stare urged him to add another
finger, getting ready for what was soon to come.
 
“Fuck yourself with this,” the teacher smirked, pointing between his legs. He
had taken the opportunity to roll the condom onto his length.
 
Akaashi didn’t need to be told twice as he placed a leg on either side of
Kuroo, lining himself up before sinking onto the man. “Sensei,” his arms
wrapped around the others neck as he got used to the intrusion. Soon enough a
steady rhythm was made.
 
“What would people think if they saw you like this? See you fucking yourself
with my cock?” A shiver of excitement ran through the smaller boy’s body. “I
bet you’d like that, wouldn’t you?” Feeling Akaashi clench around his length
was all the proof he needed. “You wouldn’t want it to stop there, just
watching, would you?”
 
This time a small gasp was heard. Cat-like eyes studied the boy on him – it
didn’t come from him, he was certain, though the student didn’t seem to have
heard. He then glanced at the door, catching a peek of grey and black hair. A
smirk danced on his lips as he returned his attention to Akaashi.
 
If Bokuto wanted a free show, he was going to get one.
 
“Turn around,” he murmured, Akaashi obeying the simple command. His back was
now pressed against the front of Kuroo’s shirt, his own having been discarded
when this had all started.
 
As Akaashi continued to fuck himself onto Kuroo, tanned fingers roamed the
younger’s body, each stopping at a nipple to tweak them, soon sharp tugs
causing loud moans. Kuroo bit at places he knew would be covered by the
uniform, sucking angry red marks onto the pale skin. His hands then moved
lower, gripping beneath Akaashi’s thighs to lift and spread both his legs,
swivling ever so slightly so he knew his colleague could get a better look of
the student’s delicious hole as he fucked into it.
 
“I bet you’re thinking of it now, someone walking in on me as I’m fucking you.
They’d see how much of a whore you truly are. Maybe they’ll think this is how
you get your high grades, letting teachers use you as their own personal
fleshlight”
 
Bokuto noticed Akaashi’s cock twitch, and as much as he felt dirty watching the
situation, oh was it a sight. His hands had slipped into his pants now, strokes
trying to match the rhythm the two set.
 
“Watching wouldn’t be enough though, would it,” he brought up the previous
subject, especially now that he knew that someone was watching. “You’re such a
cockslut I bet you’d want them to join in.”
 
Moans were slipping past Akaashi’s lips along with incoherent babble as the
words turned him on more, if it were possible.
 
“Would you want a dick at both ends, fucking you in both holes?” Kuroo let one
leg loose, dropping it unceremoniously on the outside of his lap so that
Akaashi would remain spread. The free hand ventured downwards, Akaashi
pleadingly looking at the limb hoping it would wrap around him. Instead, Kuroo
let a finger trail lower, teasing the already filled entrance, “or would you
want a second dick in here, filling you up?”
 
Akaashi swore at the thought, cock leaking. “Yes,” he managed to croak out, the
thought of being filled completely exciting him to no end.
 
Kuroo peered at the door, though it seemed like his brawny friend didn’t seem
to understand the invitation. Shame, really. So instead, Kuroo quickened his
pace. “Two can’t be enough to satisfy you, could it Akaashi? You might as well
be the school’s cum dump.” His free hand was now wrapped around Akaashi’s
throat, squeezing.
 
“No one would expect it, the quiet, beautiful Akaashi Keiji,” he released his
neck in order to hear the appealing moans and whines escaping the teen, “is the
biggest whore there is. They’d line up, you know, jerking off on you, using
that pretty little mouth of yours to suck them dry. They’d use your ass, pound
into it so much that it’ll only be their plaything. A hole with no other
purpose than to fill with cum, but you’d like that. You wouldn’t even complain.
You’d want more. You have such a greedy little hole, Akaashi. Can you feel
yourself clenching around me? Trying to milk me? What a filthy body you have.”
 
“Sen-sensei,” the student mewled, placing Kuroo’s hand on his cock and ushering
for him to move. “I’m go – I’m going to-!” Was all the warning he got as he
spilled all over his teacher’s hand.
 
Kuroo’s hips began to sputter at the tightness, ramming into Akaashi with force
as he bit into the juncture of his neck and shoulder, soon reaching his limit
and spilling into him.
 
===============================================================================
 
“Bokuto? Why didn’t you meet me at the classroom?” The dark haired male feigned
ignorance as he met his colleague by the school entrance.
 
“Eh, had to hit the washroom and figured you’d be done about now,” he hadn’t
managed to hold eye contact for longer than a second, eyes always averting from
Kuroo’s gaze. Not only had he felt dirty from watching his friend have sex with
one of their students, but he had thoroughly enjoyed it, if the soiled
underwear in his bag was anything to go by. “So, drinks?” He offered in attempt
to help his mind get off the subject. He reached for his water bottle, taking a
swig.
 
“So you accept my invitation for beers and not a threesome? Harsh.” A smirk
tugged at his lips as Bokuto choked on his water, face flushing a deep red.
