After school, Hinata had gone back with Kageyama to his house excitedly. It was
Kageyama’s birthday. Hinata had already given him a gift (with plans to give
him another one on Christmas in a few days,) and wanted to give him a surprise.
Kageyama had no idea about his plans; he had expected them to eat snacks, play
a video game, and maybe cuddle a little. But nothing could have prepared him
for this outcome.
Hinata had pulled a small plastic bag out of his backpack, and a box of condoms
out of said bag. He shyly placed the box in front of him on Kageyama’s bed,
which he was seated on, and nervously picking at the sheets.
They had been dating for a few months now, and the furthest they’ve gotten
sexually was fully clothed grinding… Hinata wanted to go further, but only with
Kageyama’s permission, of course.
 
Kageyama stared at the box, before picking it up and turning it over in his
hands. He knew what this was, obviously, but he wanted to hear what Hinata had
to say. It was obvious the ginger was nervous about it.
“I’ve been thinking… I’d like to, y’know, go all the way with you, Kageyama.”
Hinata spoke softly, eyes turned down. “Happy birthday?” He squeaked out,
finally looking up.
Kageyama’s pretty blue eyes were blown wide, and his face was red all the way
up to his ears. He scrambled to get on the bed with his boyfriend, dropping the
box of condoms and capturing the other’s lips in a quick kiss. He was grateful
his mother wouldn’t be home for a few hours.
“I… um.” Tobio cleared his throat. “I like that idea.”
Hinata beamed, wrapping his arms around Kageyama’s neck and climbing into his
lap. He straddled the other as their lips met again, kisses quickly getting
heated as they usually do. Their tongues met and moved against one another,
little hums leaving their throats.
The red head eventually pulled back, face flushed and panting. He was nervous
about his next move, since he’s never really had his clothes off for a long
amount of time around Kageyama, but he trusted his boyfriend. He unbuttoned his
uniform shirt and pulled it off, tossing it aside, revealing his black binder.
He was quick to lean back in for another kiss, as Kageyama’s hands came up to
soothingly rub against his sides.
They were both already fairly aroused. Kageyama’s hips pushed up a bit to press
into Hinata for relief, which earned a gasp from the smaller boy. Hinata pulled
back from the kiss again, scooting back off of Kageyama’s lap to just… look at
him for a moment. Kageyama swiftly undid his own shirt as well and discarded of
it, since it felt way too hot in this small room.
Hinata took a deep shaky breath, before reaching up to grab at the hem of his
binder. He had had it on all day anyhow, so it was a good idea to take it off.
He got it off with ease in a few seconds flat, and Kageyama tried hard not to
stare… in case Hinata felt uncomfortable. Kageyama’s chest swelled… Hinata was
so trusting of him.
“How did you do that so fast?” Kageyama asked in awe, since binders are tight
and can be difficult to get off… He’s done his research on these things.
Hinata giggled. “Practice!” He came forward again to press a kiss to Kageyama’s
collarbone, as a hand moved to rest at the hem of Kageyama’s uniform pants.
“Can I?” He asked, looking up at Kageyama through his long, orange eyelashes.
Tobio nodded, swallowing hard as a hand came up to caress Shouyou’s soft face.
The ginger nuzzled against the other’s hand for a moment, before moving to undo
the button of his pants. Tension in the room grew thicker, as he tugged the
pants down just a bit, boxers in tow.
When Kageyama’s length sprung free, a small sigh of relief left his lips.
Hinata couldn’t help but stare for a moment, but he quickly lowered himself to
settle his body between Kageyama’s legs. This was Hinata’s first time doing
anything like this, Kageyama too, but he’s sure he’s seen enough porn to have a
decent idea of what he is doing.
Hinata’s small fingers curled around Kageyama’s cock, and he angled it towards
his lips. His tongue pressed flat against the head, which earned a small groan
from the taller boy, and he slowly inched his face forward to wrap his lips
around it.
Kageyama’s fingers curled into Hinata’s hair gently, (though Hinata wouldn’t
mind if he pulled a bit) eyes fluttering shut as he reveled in this new
feeling. Hinata’s head started to bob and his tongue was pressed up against the
underside as he went, and Tobio felt like he was in Heaven.
What couldn’t fit into Hinata’s mouth was taken care of by his hand, and his
head started a steadier rhythm as he got used to it. He was also careful with
his teeth, but of course, sometimes they got in there clumsily. Kageyama did
not mind at all, it still felt great.
“Nn-- Hinata… I want-- you…” Kageyama’s hand moved to cup Hinata’s face again,
gently pulling it up so their eyes can meet. Tobio’s beautiful blue eyes were
hazed over with such lust…
Hinata licked his lips and looked up at Kageyama, tilting his head. He knew
exactly what Kageyama meant, but he still wanted to clarify. “You want me to
what?”
Tobio averted his eyes. “You’re really going to make me say it?” Hinata nodded,
and he huffed. “I want… to fuck you.”
“So vulgar, Tobio!” Hinata joked, before moving to wriggle out of his bottoms.
He was now completely bare in front of Kageyama for the first time, and he
couldn’t help but feel self conscious. Kageyama pushed his own bottoms off
completely and kicked them aside, completely exposing himself also… hoping it
would ease Hinata’s nerves.
“You’re… so handsome.” Tobio murmured, leaning forward to press kisses against
Shouyou’s cheek and trail them down his neck. The smaller boy couldn’t help but
smile, hands lovingly running down Tobio’s arms as his neck was attacked with
kisses.
“Touch me… please.” Hinata panted out, spreading his legs and taking a hold of
Kageyama’s hand to guide it there. Kageyama nervously nodded, trying to
remember the few times he’s watched porn curiously. His pointer and middle
finger ran over Hinata’s clit, which earned a jolt from the ginger.
Kageyama rubbed his fingers in slow circles over Hinata’s clit, carefully
watching Hinata’s face for his reactions.
“Hn-- Ah-- Tobio…” Hinata kissed Kageyama’s cheek sloppily, before reaching
down to gently push at Kageyama’s hand. At first, Kageyama thought he wanted
him to stop, but then Hinata specified. “Finger me, please…”
Oh. Kageyama nodded, kissing at Hinata’s neck again once before gently pushing
a finger in. Hinata let out a low moan and nodded, biting his lip as he watched
Kageyama’s finger disappear inside him. Tobio gently curled his finger, pushing
it in and out, before adding a second. Hinata praised him and coaxed him to
keep going, and he added a third eventually, which had Hinata melting in his
hands. Moaning and gasping, making the most beautiful sounds Kageyama has ever
heard.
“I’m… I’m ready.” Hinata squeaked out, and Kageyama nodded, pulling out his
fingers. He licked them clean, which caused Hinata’s face to flush further, and
reached for the box of condoms. He clumsily opened it, which caused a few
condoms to fall onto the bed. He picked them up after mumbling a small apology,
which caused Hinata to giggle. Kageyama finally got a hold of a condom,
unwrapping it and making sure to put it on himself properly.
Shouyou reached his arms out, and Tobio came closer so he could wrap them
around him tightly. He pressed kisses against Kageyama’s neck, even leaving a
mark, before mumbling a soft “Go ahead” and laying back.
Kageyama nodded, positioning himself carefully at Hinata’s entrance, and
pushing in very gently with a small groan. Hinata gasped and gripped at
Kageyama’s shoulders, legs wrapping around the other’s waist to pull him in
closer. He felt Kageyama stretching his walls, and even if there was the
smallest sting, it felt so fucking amazing.
Tobio waited for Shouyou’s permission to continue, and once he got it, he
pulled his hips back and pushed them forward again gently. They both made a
whine at the same time, which caused another giggle from the cute ginger. He
kills Kageyama. Kills him with cuteness.
Soon enough, Kageyama’s hips were making a steady rhythm and moans were echoing
off the room’s walls. This newfound pleasure was overwhelming for the both of
them. Hinata’s adorable moans and whines spilled out one after another, high
pitched and desperate sounding. His back arched and he gripped at Kageyama's
shoulders harder, bound to leave marks where his nails dug in.
“Ahh-- Tobio, s-so good…” Hinata whined, toes curling and thighs shuddering as
he grew closer with every movement.
“Hi… Hinata--”
“Tobio, say… say Shouyou-- please...”
“Shouyou--” Kageyama groaned out finally, dropping his head into his
boyfriend’s shoulder. He was so close… So, so close.
“Tobio, mmh… I’m getting close…” Hinata squeaked out, and Kageyama kissed and
sucked at his neck, sure to leave a mark that wouldn’t be hidden easily. “Don’t
stop-- Don’t stop don’t stop…”
“I’m… close… too.” Kageyama groaned out, continuing his movements desperately.
Hinata reached between them to rub at his clit, to help himself along.
“Let’s-- let’s cum together.” Hinata suggested with a whine, thighs shuddering
hard.
Kageyama nodded, feeling his orgasm build up. His hips moved faster and faster,
biting down on Hinata’s shoulder to muffle the loud moan that ripped through
him when he came.
Hinata came soon after, letting himself moan out loud - a moan of his
boyfriend’s name - as he squirted hard between them, surely making quite a
mess. Kageyama gasped when he felt the wetness, looking down at Hinata’s face,
then looking down at the mess between them.
“You can…?” Kageyama started, but his voice trailed off as his face flushed a
deeper red.
Hinata giggled, kissing his boyfriend’s face all over. “Mm-hmm.” He hummed, as
Kageyama slowly pulled out with one last groan. They both panted hard and
lovingly stared into eachother’s eyes for a moment, before Kageyama cleared his
throat and started getting up.
“You can stay there, I’ll clean you up.” Tobio offered, and Shouyou was glad.
His orgasm really tired him out, and he wasn’t sure he can move quite yet… His
legs were shuddering softly, and he was still panting a bit.
Once Kageyama went to the bathroom, discarded of the condom, and cleaned
himself up, he grabbed a damp cloth and brought it to Hinata. Hinata thanked
him, letting Kageyama wipe him down with it.
“Can I borrow a shirt of yours?” Hinata asked, and Kageyama nodded. Kageyama
reached into one of his drawers and pulled out one of his shirts, handing it to
Hinata. The smaller boy pulled the shirt on, enjoying how he was swimming in
it.
Kageyama pulled on boxers before climbing back into the bed, opening his arms
for Hinata. Hinata beamed, grinning as he came closer and let himself be
engulfed by Kageyama’s strong arms.
Shouyou pressed a kiss against Kageyama’s jaw, softly purring out another
“Happy birthday.” and tacking on an “I love you.”
“Thanks…” Kageyama started, heart thrumming in his chest. “I love you too.” He
truly meant it, too. He loved Shouyou with every fibre of his being… He was one
of the best things to ever happen to him.
