     Enjoy
See the end of the work for more notes
“K-Kageyama, what are you doing?” Hinata moaned out as he was pushed roughly up
against his locker. Kageyama nipped at the shorter boy’s neck, his weak spot.
Kageyama let his hands roam under Hinata’s shirt, dragging moan after moan out
of his boyfriend. If Hinata didn’t stop him now, he wouldn’t be able to resist
his advances, and this was not the first time Kageyama had done this after
practice.
“Kageyama! S-stop, we can’t do this here.” He said, pushing him off. Kageyama
rested his head on Hinata’s. “Where did that come from?” Hinata asked.
“I dunno...Just want you so bad” He said after a moment
“When we get home, ‘kay? We still have practice.” Hinata reasoned, and earned
an approving nod from Kageyama.
This wasn’t the first time Kageyama had done this sort of thing. It’d been
happening a lot recently, and he couldn’t figure out why. He thought about all
of the times he could remember: after practices, and more frequently during
exam and testing periods, and tried to figure out if there was anything that
connected them, letting his hair down as he gathered his things and his
thoughts. And then it hit him.
 
~~~~~
It started at the beginning of their second year of high school. He decided to
grow out his hair. It started as a decision Hinata made in an effort to somehow
channel the strength of the now graduated Asahi, as if mimicking his hair would
somehow grant him similar strength to the graduated ace.
The length of his hair wasn’t the only change that had most of his teammates
surprised. Hinata had grown a few inches himself, a fact he loved, and that
Tanaka and Nishinoya had been so proud when they saw how much he’d grown,
though Noya was a bit jealous at how much taller Hinata was than him now.His
jumping ability didn’t diminish, either, his height only added to his jump
height. It had surprised their former teammates as well, Suga especially fawned
over him
“You look so grown up!” He’d exclaimed while pulling Hinata into a tight hug.
“Daichi look at him! He’s almost as tall as me”
“Trying to copy your old ace, huh?” Daichi had said, mussing up Hinata’s hair.
“And you finally got your growth spurt! Seeing you this tall somehow makes me
feel even older than I am.” Asahi himself was surprised, and a little honored
at the sentiment behind Hinata’s new hair, and he’d given Hinata one of his old
hair bands and a few hair ties. Hinata treated them like little treasures.
 
Out of everyone, Kageyama appreciated Hinata’s new look most. When Hinata
decided to keep his hair long even though it had no added benefits to his
volleyball skills, as the team expected it wouldn’t, Kageyama was admittedly
very happy.
He had made an unconscious habit of playing with Hinata’s hair. Whenever the
two had downtime, whether they were on the bus to a match, or just relaxing at
either of their houses, Kageyama often found himself carding his hands through
the waves of his boyfriend’s orange locks, and Hinata couldn’t complain about
the added attention.
That wasn’t quite what was frustrating Kageyama though. Hinata realized that he
had made a habit of tying his hair up for various reasons. He tied it back for
practice, he tied it back when he did homework, or studied. He also realized he
always put his hair up whenever he and Kageyama had sex. Hinata realized that
he had mentally conditioned his boyfriend to associate sex with his hair being
pulled back
He had pulled a sexual Pavlov...
Of course, this was just a theory, and theories needed to be tested out.
Thankfully, Hinata was more than happy to test out his theory, and Kageyama
certainly wouldn’t be against it.
~~~~~
After they finished up with practice, Hinata let his hair down, and Kageyama
seemed to have cooled down since the locker room earlier. His family was out of
town, so he and Kageyama would have the house all to themselves for the
weekend. It was the perfect time to test his theory.
“So...Whatcha wanna do?” Hinata asked as they sat in his living room.
“I still feel gross from practice… Mind if I take a shower?” Kageyama asked.
“Oh yeah, of course!” Hinata said. “I think I’m gonna get my homework out of
the way.” He said, grabbing a binder out of his backpack.
“You? Doing homework right away? Are you really my dumbass Hinata?” Kageyama
asked teasingly. Hinata decided to fight back.
“You act like I never do homework, I’ve gotten a lot better about doing my
homework since last year.” Hinata said, pulling his hair into a loose ponytail
and flashing a quick grin. He could see Kageyama stiffen up a bit, a dazed look
like he was lost in thought. It wasn’t hard to figure out what Kageyama was
thinking about as a blush stained his cheeks. Hinata had him.
“You okay there, Bakageyama?” He asked, the question snapping Kageyama out of
his daze.
“Huh? Oh yeah, just got...distracted.” Kageyama said.
“Oh. You were staring at me, I thought there might be something on my face or
something.” Hinata said, feigning innocence. Kageyama lingered a little longer
as Hinata pretended to begin his reading homework.
“I still can’t believe you’re actually doing homework.” Kageyama teased. “When
did you become a good student.”
“Shut up and go take your shower before I kick you out.” Hinata teased back.
Suddenly Kageyama’s lips were on his, and he was pushed on his back as Kageyama
crawled on top of him.
“Forget your homework. Shower with me.” Kageyama whispered into Hinata’s ear
once they separated, he emphasized each command with a thrust against the
smaller body below him, already hard against Hianta.
“But my homew-”
“Shower. Now.” Kageyama said, biting at Hinata’s neck.
“Okay, okay.” Hinata moaned out. He may have misjudged just how much this might
work. Suddenly, he was hoisted up into Kageyama’s arms, and carried to the
bathroom, kicking the door shut behind them and setting Hinata down. The two
quickly stripped, Kageyama turned the water on as Hinata let his hair down.
“Wait.” Kageyama said. “Do you-”
“Back of the cabinet, under the sink.” Hinata said reading his mind. Kageyama
searched for a moment, coming up with a small bottle of lube and a condom. He
shot Hinata an inquisitive look.
“What? No one looks in that cupboard, and after the last time I figured it
would be good to be prepared…” Kageyama chuckled.
“You even got waterproof.” Kageyama noted.
“I wanted to be prepa-”
And then he was on Hinata, pinning him against the shower wall and grinding up
against him as the hot water cascaded over them. Hinata sunk down, trailing
kisses from Kageyama’s chest down to his groin.
He gave a long lick along the underside of Kageyama’s cock, before taking as
much of it as he could into his mouth.
“Holy shit, babe!” Kageyama nearly yelled, grabbing the wall for support, weak
in the knees from the sudden attention. He brought his other hand down to
Hinata’s head, grabbing a fistfull of the shorter boy’s hair as he started to
slowly thrust into the warm mouth in front of him. Hinata, for his part, did
his best not to gag as Kageyama fucked his face. Once Kageyama felt himself
getting close, though, he pulled Hinata off his cock and helped him up.
“Want you.” Hinata moaned into his ear. Kageyama grabbed the container of lube,
and poured some of the cool liquid on his hand, sliding it behind Hinata, and
slipping a finger inside of him.
He captured the smaller boy’s lips with his own as he added a second finger,
Hinata moaned into the kiss as Kageyama spread him wide open.
“Kag-eya-ma. Need more.” Hinata moaned after a few minutes. “Want you now.”
Kageyama didn’t need to be told twice. He grabbed the condom, and pulled it on
before slathering more of the lube on his cock. He turned Hinata around,
pushing him up against the wall, lining his dick up with the smaller boy’s
entrance.
“Ready?” He asked, his voice low, and dominant. Hinata nodded, and he felt
pressure against his hole as Kageyama pushed into that tight heat with a
contented sigh.
“Always so tight for me, babe.” Kageyama moaned into Hinata’s ear. “S’like you
were made to take me.” He thrust all the way in, making Hinata moan loudly.
“Y’like that, babe? D’you like it when I fuck you like this?” He moaned into
Hinata’s ear as he started to build up a rhythm.
“Y-yeah, fuck! I love it” Hinata moaned. “I love you.”
“I love you too, baby. Kageyama said. He gave a few more thrusts, and then he
pulled out, leaving Hinata feeling empty.
“Kagyamaaa” Hinata whined. “I need yooou!” Kageyama spun him around.
“Wanna try something.” Kageyama said. Hinata felt weightless again as Kageyama
lifted him up to eye level, and pressed his back against the wall. He wrapped
his legs around Kageyama’s waist and his arms around his neck as Kageyama
pushed back into him, burying himself to the hilt in a single thrust.
“Wanna see your face while we do it.” Kageyama moaned as he started thrusting
again, kissing him as they built their pace back up. In this position, he was
hitting Hinata’s prostate with nearly every thrust, turning the boy in his arms
into jelly as he fucked up into him.
“M’close, baby.” Kageyama moaned, his thrusts starting to grow more desperate
and irregular.
“Kageyama, please… Wanna cum together” Hinata whimpered. Kageyama wrapped his
hand around Hinata’s cock, gave it a few pumps, and that was all it took.
Hinata let out a high pitch moan, and he heat pooling on his chest. Kageyama
gave a few more thrusts and let out a rough growl as he thrust in a final time,
moaning Hinata’s name as he followed him over the edge.
They stayed like that for a few moments, breathless, drinking in the afterglow
of what just happened, before Kageyama slowly set Hinata down, the latter of
the two keeping a tight grip on the former’s arm to keep steady. Kageyama
brought a hand to Hinata’s chin, and tilted it upwards, planting another short
kiss on his boyfriend’s lips.
“God. Love you so much, baby.” He said, smiling down at Hinata. Hinata nuzzled
his head into the crook of Kageyama neck.
“I love you, too.” Hinata whispered softly into his neck. The two of them
finished washing up, Kageyama removed the condom, and tied it off, throwing it
into the trash bin as they exited the bathroom.
The decision was made to order pizza, and the two of them curled up on the
couch to watch a movie while they waited, Kageyama absentmindedly playing with
Hinata’s still damp hair
“I still can’t believe I was right.” Hinata thought aloud
“About what?” Kageyama asked, confused.
“Oh, nothing important. Just a little theory I had.” Hinata said nonchalantly.
He wouldn’t soon forget what he learned that day.
