Summary
     Oikawa Tooru gives his younger setter private lessons sometimes when
     the others have all gone home.
Notes
     Happy birthday to one of the coolest gals I've met through fic
     writinggggg!! I'm going to hell for this and I don't even care, you
     deserve some birthday porn. Enjoy! (Disclaimer: No actual closet sex
     but 'closet blowjobs' wasn't a tag)
'Shhh Tobio-chan... you don't want your team-mates to hear, do you?'
The whisper is hot against Kageyama Tobio's ear and the whimper it wrenches
from him is shameful, muffled as it is with two of Oikawa's fingers in his
mouth, pressing down firmly on his tongue. Oikawa has him pinned forward
against the wall of the storage closet, pressing right up against the smaller
boy's back while they listen to the chatter of their team-mates just outside
the door in the locker room.
Oikawa hushes him again, even while his hand creeps low, into the loose elastic
of Kageyama's shorts and between the other's legs to squeeze and stroke until
the boy is scrabbling for purchase on the wall and biting down on Oikawa's
fingers in his attempt to keep quiet. The sounds are somewhere between sobs and
moans and Oikawa withdraws his fingers in favour of clasping his hand over
Tobio's mouth to make sure they aren't heard. The danger is exciting but he
really doesn't need them to be discovered like this.
'Where's Oikawa?' he hears Iwaizumi's voice from outside, sounding puzzled. No
one's able to give him an answer and Oikawa hears the sound of irritation from
his team-mate which only makes him grin.
'I think he said he was going to give Kageyama some training.' someone else
chimes in, and Oikawa laughs breathily against Tobio's ear again.
'Training.' he echoes barely above a whisper. His hand closes around the
younger boy's erection, giving it a few slow, measured stroked. 'Am I training
you well, Tobio-chan?' he runs his thumb over the head of the other's cock,
smearing the pre-come there out over it and Kageyama utters a high sound that
Oikawa quickly smothers. Kageyama's body is flushed to the point where Oikawa
can feel the heat of it through his clothes, as if the other has a high fever.
The boy's eyes are squeezed tightly shut and his face is burning red.
'Should I stop?' Oikawa murmurs as he presses forward with his hips. He's half
hard already but the friction of him rubbing up against the pert young ass in
front of him stirs him into full arousal. 'Tell your senpai to stop, Tobio-
chan, and I will. Right away.'
Pulling his hand away from Kageyama's mouth he can't help but be delighted by
how lustful the boy looks; a string of saliva hangs down his chin, his jaw
hanging open as he pants desperately while his hips seem to move of their own
accord, rutting forward into Oikawa's grip.
He doesn't tell Oikawa to stop, of course he doesn't. Oikawa hasn't met anyone
who's quite as eager to learn as Kageyama Tobio.
Oikawa groans softly against the curve of Kageyama's neck as he grinds up
against him again; even with the clothing between them, the sensation of his
cock sliding against the cleft of the other's ass is delicious and it takes
every ounce of strength Oikawa has to not strip the other boy down and fuck him
until Oikawa's name falls from the younger setter's lips in a mantra of
mindless pleasure.
But he is patient, he can wait.
Just outside the door he hears their team-mates discussing going down to the
noodle place down the road. He knows they'll look for the two of them out in
the gym, and then outside, but he also knows Iwaizumi won't allow them to look
too long before they give up and go on without them so Oikawa isn't worried. He
waits until the voices fade from the locker room and that's when he turns
Kageyama around to face him.
It's a perfect picture of spoiled innocence that heats Oikawa up in ways he
never thought possible; Tobio's eyes are watery and his cheeks red, his hands
clutch at the hem of his shirt, absently tugging it down as if he's trying to
hide evidence of the way his cock strains against his shorts. He's still so
young and inexperienced and Oikawa feels a perverse pride in being the first to
make him feel this way.
'Get down on your knees, Tobio-chan.' he says kindly, running a thumb below one
of Kageyama's eyes in a gentle, soothing gesture. 'Senpai will teach you
something new today.'
And he does, bless him, without even asking a single question he just does it
and Oikawa leans forward to brace himself against the wall with one forearm as
he looks down on his darling kouhai. It seems the boy isn't entirely clueless
as he reaches forward and hesitantly touches Oikawa through his shorts so the
older setter shivers.
'Good. You've got the right idea, Tobio... pull it out.'
Kageyama does, tugging the other's shorts down off his hips and flushing darkly
as he comes face-to-face with the other's erection and he looks questioningly
up at Oikawa as if awaiting instructions.
There's nothing Oikawa likes more than that look.
Reaching down with the hand not bracing himself against the wall, he runs his
thumb over Kageyama's lips gently before prying them apart to slip it into the
boy's mouth. Kageyama shivers and his eyes close part-way as Oikawa feels his
tongue automatically move to slide along the digit.
'You see? I don't even need to tell you, you already know what to do.' he pulls
his hand away from Kageyama's mouth and threads his fingers into the boy's hair
instead to guide him closer. 'Now do that again.'
The first soft, shy lick sends a thrill right up Oikawa's spine and he has to
bite down hard on his lip to stifle a moan. Kageyama is inexperienced but eager
to please and he licks again before taking the head of Oikawa's cock into the
his mouth and suckling at it in a way that has Oikawa's hands curling into
fists as he resists the urge to just push forward into that hot little mouth.
He moans softly and the sound seems to spur Kageyama on; he takes more in, as
much as he can before he chokes and pulls back a moment, coughing.
'Easy...' Oikawa smooths his hand through the younger boy's hair again. 'Don't
go too fast.'
Kageyama is a fast learner and he quickly finds where his limits are as well as
which actions get the most positive responses from Oikawa. Using that knowledge
he works enthusiastically at his given task and the soft, eager slurping sounds
of the sloppy blowjob are more than enough to leave Oikawa panting and rolling
his hips just slightly in rhythm with the other's bobbing head.
It's all good... the view he has of the other's lips around his cock, the soft
sounds, the way Kageyama draws back at some moments to wipe the saliva and pre-
come from his chin. Oikawa loves all of it.
'Sit back.' he orders him and Kageyama obeys immediately, leaning back against
the wall and catching his breath as he looks up at Oikawa with the kind of
expression that begs the upperclassman to assure him that he had done a good
job. Oikawa doesn't do that yet though, taking himself in hand and stroking
firmly just the way he likes it. His other hand curls tight in Kageyama's
hair... he wants so badly to fill that pretty little mouth but that's for
another time, and instead when he comes with a choked groan he makes sure to
decorate those flushed cheeks instead, spilling the milky fluid over them and
over Tobio's lips and chin.
The way the small tongue darts out to curiously taste the come on his lips is
positively sinful.
'Good boy.' he whispers breathlessly, smearing the other's lips with a finger,
thrilling in how relieved Kageyama looks when he's praised. Sitting down by him
he pulls the boy into his lap, shimmying the elastic waistband of his shorts
down as he strokes at him again and delights in the way the younger boy seems
to completely unravel at his touch, writhing in his lap, clinging tightly to
him and panting against Oikawa's neck, thighs twitching until he can't take it
anymore.
'O-Oika... wa-senpai...!'
His body tightens and Oikawa holds him close, letting him feel secure but also
delighting in being able to feel every shudder in the lithe young body as he
comes, spilling into Oikawa's fist. He bites gently at the younger setter's ear
and Kageyama whimpers, curling in tighter against him. Oikawa knows he owns
every part of Kageyama at that moment and he loves it.
'I think you learned a lot.' he whispers against Kageyama's ear, tracing the
shell of it with the tip of his tongue so that the other boy squirms and
whimpers again. 'Did you like your lesson?'
Kageyama can only find the energy for a slight nod as he nuzzles in against
Oikawa's neck and the latter chuckles as he grabs a nearby roll of paper towel
to clean them up with. The last thing he needs is to run into any stragglers
from the team on their way out and have to explain the mess.
'Don't worry Tobio-chan~ we'll have another lesson very soon.'
