Notes
     For this_prompt
It happens when they’re alone in Kazuya’s dorm room, sitting on the floor next
to each other absorbed in each other’s presence, tongues greedily exploring the
other’s mouth. The door opens, making them startle apart, both of them jumping
awkwardly away from each other, wiping their mouths hastily when just as
suddenly the door slams shut, the only evidence it was open a shoe box pushed
into Kazuya’s room.
 They look at each other with raised brows and pounding hearts before Kazuya
retrieves the box. It’s lightweight, addressed to both of them from “a friend :
)”. Kazuya gives Furuya a skeptical look.
“What is it Miyuki-senpai?”
“I don’t know,” Kazuya settles back down next to him, their knees touching.
Furuya leans closer to look.
“Have fun you two! KYAHAHAHAHAHAHAHAHA!!!!!” Furuya reads flatly careful not to
miss and “ha’s”. “So it’s from Kuramochi-senpai.”
“Must be,” Kazuya says, nervousness pulling at his stomach.
“Are you going to open it?” Furuya blinks at him, his lips red from being
kissed, which is exactly what Kazuya would prefer to be doing with his precious
free time, not being messed with by their too-observant teammate; or would that
be ex-teammate now that he and Kuramochi are retired along with the other third
years?
Kazuya pulls the top off the box and immediately jams it back on, his face
turning red.
“What is it, I didn’t see,” Furuya slips his fingers under the lid and Kazuya
lets him lift it off, watching his expression go from confused to wide-eyed as
he starts to turn red.
“Oh,” he says simply and Kazuya feels like he should be annoyed or worried that
Kuramochi slipped a shoe box full of condoms and lube into his room but mostly
he feels like laughing, and pushing his boyfriend over and straddling his lap.
“I guess we’re not as subtle as we think,” Kazuya says to get his throat
working again.
Furuya nods but he doesn’t take his eyes off of the contents of the box. He
looks at them with interest, that familiar hunger growing in his eyes and it
makes blood rush to Kazuya’s groin again. He reaches in, his hands steadier
than he feels and takes one of the condoms. It feels odd, he’s never touched
one before; it’s surprisingly squishy in the middle, the hard ring around the
outside sliding around under his fingers.
“It would be a shame to waste such a thoughtful gift,” he smirks, his heart
pounding as Furuya meets his eyes.
“Are you sure, Miyuki-senpai?”
“Yeah,” Kazuya grins, nervousness and excitement thrumming through him but no
doubt. “We won’t be seeing each other as often in a few months, we might as
well enjoy the time we have now, right?”
“I don’t like thinking about that,” Furuya tells him, voice low and Kazuya
agrees in his heart.
“I know how to stop you from thinking too much,” he snickers, his free hand
going to the back of Furuya’s head and bringing him in for a kiss. It’s
fortunate that it also stops Kazuya from thinking too much too.
They resume their kiss but the tone is different now, what was languid and
relaxed has become heightened, both of them pressing together harder, the heat
between them building until Kazuya pulls away.
“Get on the bed,” he purrs it against Furuya’s lips, a small string of saliva
breaking when Furuya’s nods his head.
Kazuya is already painfully hard when he gets up to lock the door, a precaution
he should have taken before but he always reasoned it would be more suspicious
to be “caught” with Furuya in a locked room. 
When he turns Furuya is lying down, looking at him intensely. Kazuya can’t help
grinning at him, the same mix of nervousness and excitement in his stomach as
he stops on his way to grab lube from the box on his way to the bed. He sets
their things next to the pillow and reaches for his waistband, Furuya’s eyes on
him still. He enjoys the way Furuya’s eyes follow his hands as he slowly pulls
his sweatpants and boxers down, his hard cock bobbing free.
“You too,” Kazuya says and Furuya obeys, lifting his hips and pulling his pants
and boxers down, Kazuya’s eyes taking in the hard cock and lean muscles with
pleasure. “Shirt too,” Kazuya adds and Furuya looks at him with surprise before
taking it off and tossing it aside.
They usually leave them on, easier to dress in a hurry if someone comes looking
for either the ex-captain or the current captain but if they’re going to do
this Kazuya wants to feel all of him. Kazuya slides into bed beside him,
allowing Furuya to wrap his arms around him and pull him in for a kiss, their
chests pressed together, their hips lining up.
Their skin feels good against each other, the anticipation making it more
intense, Kazuya’s hands on Furuya’s back nervous with the knowledge of what
they’re about to do. It’s not the first time they’ve done this, embraced each
other with their cocks rubbing against each other, mouths joined in a sloppy
kiss. It is the first time they’ve been completely naked like this though, had
a plan other than just rutting against each other until they came.
Kazuya relishes the sensation, his hand feeling Furuya’s back muscles move as
Furuya’s arm travels lower on Kazuya’s back, skimming along the indent at the
small of his back and cupping his ass cheek. Kazuya moans into the kiss,
pressing his cock harder against Furuya’s, his hips rocking gently. He slides
his hand between their bodies, thumb brushing against Furuya’s nipple before
finding his heartbeat. It’s going crazy, just like Kazuya’s. He could come like
this.
Kazuya pulls away, twisting to grab the lube behind him, Furuya’s hand going to
run gently along his chest. He hisses, scrunching up.
“That tickles.”
“Sorry,” Furuya says, pressing more sure against his skin, tracing the muscles.
“I don’t get to touch your chest much.”
“I’ll let you touch more of me,” Kazuya smirks, dangling the lube from his
fingers and Furuya watches it go back and forth before taking it.
“I don’t know what to do senpai…” Furuya stares at him and Kazuya laughs
softly.
He must know Kazuya has never done this either and yet he still defaults to
looking for guidance from him. Kazuya tells him to open it and squeeze some on
his fingers and he does so, a look of concentration on his face that has Kazuya
suppressing a nervous laugh as he rolls onto his back.
“Now come here,” Kazuya opens his arm and Furuya fits himself to his side,
holding his slicked fingers in the air.
Kazuya takes his wrist and guides his hand down, trying to breathe normally as
he spreads his legs wide. He lets go of Furuya’s wrist, figuring he can take it
from there, flinching when the cold lube touches his skin, Furuya’s finger
trailing down his crack until it reaches his entrance.
“Here?” Furuya asks and Kazuya nods, biting the inside of his cheek. “Should
I…” he presses his finger hard against it and Kazuya tightens, biting his cheek
too hard.
“Slower,” Kazuya says, trying to relax. “I’m not used to this, if you rush it
will hurt,” Kazuya breaths out, trying not to worry about the pain but Furuya
eases up, nodding. “Kiss me,” he commands, trying to chase away how awkward
he’s feeling.
Furuya’s lips move against his, his tongue joining Kazuya’s, the familiarity
taking away some of the discomfort as Furuya’s finger starts to rub
experimentally against him. Kazuya’s hand tangles in Furuya’s hair, giving him
something to squeeze when he starts to apply more pressure. He presses the tip
of his finger in slowly and Kazuya gasps, breaking the kiss.
“Is this ok, Miyuki-senpai?” Furuya asks against the corner of his lips.
“It’s fine,” Kazuya says. “Just a little weird, I’ll get used to it.”
Furuya pulls away to study his face, satisfied with whatever he finds he starts
to kiss Kazuya’s neck. Kazuya turns his head to give him better access as he
closes his eyes. It’s starting to feel good, Furuya’s hot breath against his
wet skin, the finger inside of him gradually sinking slower into him, pulling
out slowly before pushing back in. The sensation is still strange but it’s
Furuya, Furuya’s fingers that Kazuya loves, so much so that when they first
started messing around Kazuya found himself distracted while catching, staring
at the fingers that the night before had been wrapped around his cock.
His hips start to rock experimentally, testing the different angles until he
finds one that’s the most comfortable. He stops Furuya long enough to take one
of the pillows out from under them and wedge it under his hips, lifting himself
where it felt the best. When Furuya resumes he feels more relaxed, only
stilling when Furuya starts to press a second finger against his hole. It goes
in easier than the first, making Kazuya’s breathing speed up as he spreads his
legs wider.
“I’ll move,” Furuya says against Kazuya’s collar bone and he shifts between
Kazuya’s legs, his free hand massaging the inside of Kazuya’s thigh.
Kazuya spreads his legs wider, Furuya’s fingers sliding in easier now, dragging
the first moan from his throat. He turns his head from the side to look at
Furuya, feeling the marks that Furuya left on him when his neck moves, meeting
Furuya’s heated gaze.
It hits him then, making his heart skip a beat, how exposed he is; spread wide
open in more ways than one as Furuya kneels between his legs, fingers flexed on
his thigh while his other’s move steadily in and out of him. He can feel his
cock leaking against his stomach. Part of him wants to hide his face or at
least take off his glasses so he’s not so self-conscious about how Furuya’s
looking at him but then he’ll miss out on Furuya’s expression. Furuya wets his
lips, looking between Kazuya’s face and where Furuya is fingering him.
“Miyuki-senpai, have I ever told you you’re really beautiful?”
Kazuya closes his eyes, feeling the heat creep into his face and his breath
catch in his throat.
“You’re embarrassing me,” Kazuya says and feels Furuya’s apology against the
inside of his thigh.
He leaves a trail of kisses, making Kazuya’s sturdy thighs shiver as he travels
upward. Kazuya opens his eyes again when he feels hot breath against his cock.
Furuya kisses up the length before taking the tip in his mouth, Kazuya
suppressing a loud moan. The fingers inside him start to move apart, stretching
him wide. It hurts a little but there’s a current of pleasure too, enhanced by
Furuya’s mouth moving on his cock. Kazuya barely notices when Furuya slips a
third finger into him except that it touches something that sends a white hot
flash through him, making his toes curl and his hips jump, Furuya’s throat
making a noise.
“Sorry,” Kazuya says, gripping the blanket. “I don’t know what that was but it
felt good.”
Good may have been an understatement. Furuya resumes his movements, looking up
at Kazuya with his mouth full of cock and Kazuya can’t help but wonder if he’s
ever told Furuya that he’s beautiful.
“Are you ready, senpai?” Furuya asks, letting Kazuya’s cock drop from his
mouth, wet and hot and Kazuya nods, trying to stay relaxed as Furuya withdraws
his fingers.
He takes the condom with nervous fingers, sitting up and feelings oddly empty
in the absence of Furuya’s fingers as he tears open one of the ridged sides of
the package. It takes him a moment to figure out which way it’s supposed to
roll before he places it on Furuya’s hard cock and rolls it down, Furuya’s skin
hot even through the synthetic material. It smells like rubber.
 Furuya catches his mouth in a needy kiss, pushing on Kazuya’s shoulder to make
him lie down but Kazuya resists, makes Furuya rub more lube on his cock in case
the condom isn’t lubricated enough before lying back down.
He tries to remember how he felt while Furuya was fingering him and it started
to feel good instead of worrying about how his cock will feel. Furuya hovers
over him, looking down between their bodies as he lines himself up, the tip of
the condom brushing Kazuya’s entrance and making both of them inhale. Kazuya
feels a little guilty, he hadn’t even thought about how hard and needy Furuya
must be while he was working Kazuya open.
He keeps that in mind as Furuya presses the tip against him, relaxing as best
he can as it slides in, stretching him back open. The moan Furuya lets slip
from his lips, the way he looks at Kazuya with half-lidded eyes makes his cock
twitch.
“Senpai,” Furuya moans, slipping in further. “That feels good.”
“Yeah,” Kazuya says, staring at Furuya’s face. It hurts a little, bigger than
the fingers that were in him but it’s turning quickly to pleasure the way
Furuya is looking at him, making Kazuya feel the sexiest he’s ever felt.
He gets half way in before pausing, kissing Kazuya long and hard. He stays
there a moment and Kazuya starts to wonder if he somehow came already when he
starts to move again, pulling out slightly before pushing back in further than
before. It makes Kazuya’s toes curl, moaning into Furuya’s mouth.
He does that until he’s all the way inside Kazuya, the sensation of fullness
overwhelming, making Kazuya pant against Furuya’s lips. It feels intense as he
starts a slow rhythm, Kazuya keeping the angle comfortable for himself, lifting
his hips a little more until Furuya hits that spot again that makes him moan
and thrust back harder.
“That’s good,” he says breathlessly, reaching in between them to touch his own
cock. “Good job Furuya.”
Furuya moans, burying his face in Kazuya’s neck, kissing the marks he left
there earlier. It does feel good, his mind starting to blank out as Furuya’s
rhythm speeds up.
“Miyuki…senpai…” Furuya breaths. “I can’t hold back,” he moans, moving faster,
harder, wet noises coming from between Kazuya’s legs and sending things back
over to being slightly painful but Kazuya goes with it, pumping his cock
faster.
Kazuya feels Furuya’s orgasm start to build, familiar enough with his body to
spot the ways his breathing changes, how his body starts to move differently,
entirely on instinct as he chases his orgasm. Kazuya follows him, lying back
and letting Furuya set the rhythm as he concentrates on jerking himself off,
pre-come dripping onto his stomach.
“I’ve told you before,” Kazuya pants, smiling against Furuya’s cheek. “You
don’t have to hold back with me, Furuya.”
That’s all it takes, Furuya grunting and burying his cock deep inside Kazuya as
he comes, hips jerking erratically before slowing. Kazuya follows him, spilling
himself between them with a moan, coming in hot pulses across his hand, moving
his hips for more friction against Furuya’s cock. He finds Furuya’s lips,
cupping Furuya’s face with his clean hand, pushing his hair off his sweaty
forehead.  
“That’s one down,” Kazuya says and to his surprise Furuya laughs softly.
He presses his hand against his chest to feel it more fully.
“Looking forward to it, Miyuki-senpai.”
