Summary
     Oikawa's sex drive is driving Iwaizumi crazy, so he simply decides to
     return the favour.
     Also it has nothing and everything to do with snails.
Notes
     This is 69000% self indulgent but I needed it because 1: We all know
     Iwa-chan is BOSS at eating out (even tho I feel that I didn't do a
     very good job at showing his skills) and 2: Because I think about
     trans boy Oikawa A LOT
“Iwa-chan, I’ll shower real quick so wait for me kay?” Oikawa didn’t turn
around while heading to the shower room but Iwaizumi could practically hear the
mischievous smile on Oikawa’s face, which was all good and well, or at least
nothing out of the ordinary. Still, Iwaizumi’s frown deepened slightly at
hearing those words; There hadn’t been a single day ever where they didn’t go
home at the same time so for Oikawa to even feel the need to mention it meant
something was up.
 
There was no doubt, it was that again.
 
“See you tomorrow Iwaizumi-senpai!” His thoughts were interrupted and he turned
to face the person calling out to him. “Yeah good work today,” Iwaizumi waved
at the first years as they left the changing room and shut the door behind
themselves. The sound echoed in the now empty and bleak room and Iwaizumi was
left in a heavy silence on the bench where he sat, hair still damp from his
shower. The peaceful moment didn’t last for long, however, as Oikawa came back
into the changing room in his boxers and a T-shirt.
 
Their eyes locked and even though Oikawa was at the other side of the room
Iwaizumi could clearly see his fully blown pupils. If he wanted to avoid this
he knew he’d have to act fast so he took his bag, stood up from the bench and
started walking the short distance towards the door. “Hurry up and put on some
pants so we can get going already,” Iwaizumi was just reaching for the handle
when two strong hands grabbed his shoulders and spun him around, making him
completely lose his balance and fall heavily against the iron door with a loud
thud.
 
Before he had time to voice his discomfort Oikawa*s mouth was on his own, an
eager tongue probing it open, and if it wasn’t for the sound of his bag falling
to the ground he probably would have lost himself in the kiss (the guy knew how
to work his mouth, big deal). He came back to his senses and pushed Oikawa
away, he tried to look angry but knew from how hot he felt that his grumpy
expression wouldn’t really be enough to make it convincing. “Will you calm down
a minute,” the words came out somewhat strained as Oikawa had opted to kissing
his neck; sucking right where he was the most sensitive, hands and fingers
roaming over Iwaizumi’s abdomen under his shirt. “Can’t you at least wait until
we’re at home, people could still come here you know,” in opposite to Oikawa,
Iwaizumi wasn’t thrilled about the idea of being walked in on doing anything
more intimate than talking. Oikawa actually slowed down and lifted his head
from Iwaizumi’s nape, he looked into the shorter males’ eyes for a moment
before a smirk spread across his face and he whispered “ I’ve patiently held
back since morning practice, I’m not gonna wait a moment longer.”
 
With Iwaizumi’s back still against the cold door Oikawas’ hands moved down his
sides to his hips, grabbing at his butt through the layer of fabric, and not
before long Oikawa’s eyes were no longer looking at Iwaizumi’s face but
directly at his crotch as he got down on his knees in front of him. His slender
fingers unbuckled and unzipped Iwaizumi’s pants without hesitation and when he
pulled them down slightly he triumphantly snickered “Well it sure looks like
someone here is glad to see me, don’t you think, Iwa-chan?” The teasing
expression on his face did it for Iwaizumi, he wasn’t gonna let it end like
this; ever since Oikawa started his hormone therapy around a month ago his sex
drive had been fluctuating and sometimes, like today, it was almost
overwhelming. Even so he just couldn’t stand the thought of letting Oikawa have
his way with him so he promptly grabbed his hair and pulled his head further
away from his underwear and hardening member. “Stand up and go sit on the
bench, you moron” His voice came out more commanding than he thought it would
and even though there was a shade of confusion in Oikawas’ dark eyes he
actually did as he said and started walking towards the benches. Iwaizumi made
sure to lock the door before he too went back to where his boyfriend was
sitting, one hand keeping his unzipped pants from gliding down to his ankles,
with only one resolve in his mind; if anyone was going to be walked in on
without their pants on, it wouldn’t be him.
 
 
 
Oikawa’s soft underwear were illogically uncomfortable and his entire body felt
like it was on fire, he was positive that this was the horniest he’d ever been
and enduring both lessons followed by hours of volleyboll practice had been
almost impossible. It seemed Iwaizumi hadn’t noticed him ogling him all day
long, he really was too oblivious, and after lusting for him basically since he
woke up said person had denied him what he wanted once again.
 
The word frustrated didn’t even begin to describe how he felt.
 
He was just about to start whining to his cruel boyfriend about how very unfair
he was being but not a single word left his mouth, instead his pulse went up
when a new wave of arousal washed over him as Iwaizumi spread his legs apart
and positioned himself, kneeling in between them. Iwaizumis’ hands started
moving, stroking up his thighs past his hips and back again, nails gently
grazing his skin. His mouth moved to his stomach and he placed soft kisses
everywhere between his bellybutton and the hem of his boxers. Only this
stimulation had Oikawa almost losing his breath, loudly breathing through his
nostrils, and his entire lower area was pulsating. He tried muttering out a
short “Iwa-cha-,” but before he even finished Iwaizumi was backing of slightly,
pushing his fingers inside the elastic band of his boxers and pulling them down
to his ankles, leaving him half naked on the wooden bench. Oikawas’ legs were
once again pushed aside and he heard and felt his swollen lips separate with a
slick sound, that feeling alone had his inside clench and he closed his eyes
and try to calm down his breathing; he wasn’t gonna cum before the good part
even started, at least he would try not to.
 
“You are really wet you know,” Iwaizumi murmured as he inched closer, letting
his tongue slide against the soft skin on the inside of Oikawa’s thigh. “If I
didn’t know better I’d say someone was happy to see me too,” normally he
wouldn’t let such an unusual sass reply go unnoted but Oikawa could only
produce a smile and a vague snorting sound, head resting against the wall
behind him. Iwaizumi just kept moving his mouth further up the inside of his
thigh, hands keeping them apart by the knees, and soon reached the outside of
his lips. He kissed around them on both sides then trailed his tongue up the
edge, all the way above his clit and down the other side, still not touching
his most sensitive parts. Oikawa’s frustration was turning into pain, his loud
breathing became faster as his desperation grew deeper and he reached for
Iwaizumi’s short hair and tried to push his face to where he needed it to be.
“Iwa-chan. . please, don’t be such a tease,” this time Iwaizumi snorted, maybe
celebrating his victory, and Oikawa’s grip on his hair tightened as he started
moving his tongue in soft circles around his swollen clit.
 
“Aah,” Oikawa could no longer contain the moans he’d been holding in for so
long as the pleasure rushed through him. His boyfriend moved down his slit and
sucked at his inner lips and then moved up again, circling and flicking his
clit. He moved the hand not gripping onto Iwaizumi’s hair to his mouth in an
attempt to stifle the sounds he made but there was no doubt that anyone going
by the clubroom would hear that something was going on inside. He felt himself
getting closer and closer when Iwaizumi moved his hands upwards again, found
the bottom of his T-shirt and, with some A+ teamwork, removed it from his
torso. Under it waited yet another layer of fabric; his binder. Iwaizumi looked
him in the eyes and asked “can I take it off?” His eyes were somewhat worried
and Oikawa tried to call it off with a fake smile, “aaaw, and here I even went
through the trouble of putting it on after my shower.” Iwaizumi kept looking at
him, “I know you don’t feel as comfortable but I don’t want you to get hurt
again.”
 
Oikawa agreed that it was uncomfortable; without it he felt naked, really
naked, but the fear when he almost passed out from breathlessness was probably
worse. He didn’t want to experience that again, and especially not have
Iwaizumi experiencing it again, so he nodded and let Iwaizumi help him get out
of the tight, maybe too tight, clothing. The first breath always felt the best
and Oikawa relished in the immediate feeling of freedom with a long, deep
breath. “You really care about me don’t you Iwa-chan”, he exhaled with closed
eyes and felt a hand on the back of his head push him down to soft lips with a
peculiar taste, his own taste, but soon the kiss ended with Iwaizumis’ words
“of course I do, Shittykawa,” and Oikawa couldn’t help but smile. “Don’t call
me that at a time like this, we were almost having a moment there!” Their
smiling mouths met again and Oikawa deepened the kiss, savouring the slightly
unusual taste, when he felt the tips of Iwaizumis’ middle- and index finger
sliding up and down his still aching slit. Every time the digits turned at the
top and touched his clit he moaned into his boyfriends mouth and when Iwaizumi
inserted the fingers, hooking them upwards his stomach and pressing against his
sensitive insides, he involuntarily threw his head back in pleasure with an
audible “ah yes right there, don’t stop!”
 
Iwaizumi raised the pace, fingers consistently pressing against that oh so
sweet spot and moved his other hand to Oikawa’s clit and rubbed it relentlessly
and fast, leaving the otherwise talkative boy completely speechless, open mouth
and ragged breathing. “Iwa-cha-, I’m. . ,” Iwaizumi further increased the
pressure and sultry whispered “ say my name, Tooru.” He then replaced the
rubbing fingers with his mouth, sucking and flicking Oikawa’s clit (the guy
knew how to work his mouth, he sure was a lucky boy) and as the fingers kept on
pumping inside him Oikawa felt his body tense up. “Ha- ah. . Hajime. . Haji-. .
,” Oikawas’ abs were convulsing and his entire legs, down to his toes, cramping
as he came with Iwaizumis’ fingers inside him; feeling how his insides
contracted and contracted around the digits almost made him ecstatic and with
Iwaizumi’s tongue still on his clit the contractions kept on coming until he
thought the orgasm would never end.
 
After what felt like an eternity of full body cramps Oikawa once again leaned
against the wall, breathing heavily. “Wow, Iwa-chan that was amazing,” Oikawa
opened his eyes and looked down at the boy now crouching in front of him, “I
never thought I’d have YOU coming onto me at school, Iwa-chan really is such a
perv.” Iwaizumi just sighed and stood up, revealing a rather evident bulge in
his pants, Oikawa slyly licked his lips “and I know exactly how to pay you
back.” He reached out from where he sat but Iwaizumi turned away saying “you
don’t have to pay back anything, that one was on the house.” Oikawa still
didn’t seem convinced, “ but what about you?” Iwaizumi looked over his shoulder
to seeing Oikawa pointing towards his crotch and exclaimed with a hint of red
on his cheeks, “I’ll take care of that later, besides right now we seriously
need to focus on getting the hell out of here before we get locked in for the
night,” he started moving towards the restroom, “I’ll go clean up so promise
you have those pants on when I come back this time!”
 
Oikawa put on all his clothes in record time, took his bag and went to wait by
the door for Iwaizumi, who came out from the toilet with a slight frown on his
face. Oikawa held up the door for him, lowered his voice and said “ you know I
wouldn’t mind spending every night at an empty school if it was with you Iwa-
chan.” Iwaizumi passed him without a word, but Oikawa knew for sure he saw a
small twitch in the corner of his mouth and still a tinge of red on his cheeks
as the door closed behind them and he said “shut up, Shittykawa.”
