Summary
     For better or for worse (probably for worse), he loved his messy,
     eager little brother.
Notes
     I WAS NEVER GOING TO POST THIS but it's YuHaya night on AO3
     apparently, so it's now or never.
     Anyway here's my obligatory Incest disclaimer: Incest is unhealthy,
     don't do it. I don't condone it and I acknowledge that what I've
     written is problematic. If you are disgusted by incest fic (or on
     that note, underage fic, too) though, why are you here, click the
     back button. Seriously. Please.
     That said, enjoy my horribly trashy unrealistic anime porn, (mostly)
     guilt-free. I blame Hato and Lyn completely. (Also KT since this
     started out as just some dumb drabble for her.)

“Aniki,” Yuuto whimpered into the wall, worrying his thick bottom lip as he
struggled to spit out a coherent sentence, “Aniki wait—I want to look at you
too…” 
Hayato ignored his brothers pleas, more focused on the weight of the boy’s pert
ass squeezed into his palm, small yet supple and the skin smooth and warm. He
dug his fingers into what little meat there was, then slid lower between the
cheeks to rub against a more tender place. 
“Aniki…” Yuuto repeated wantonly, half for show as he knew using the word in
such a way made Hayato dizzy. 
“Honestly, Yuuto...wearing this kind of thing…” Hayato lulled, lowering his
head to ghost his breath down the back of Yuuto’s neck. He had one hand pushing
on the small of the younger boy’s back to force his hips up against the wall
while the other rubbed him slowly through a pair of satin panties. “Where did
you even get these?”
“I asked a girl from school to trade with me....” he admitted, half-peeking
over his shoulder in an attempt to gauge his older brother’s reaction. 
“What did I say?” Hayato warned, though his tone was gentle—more teasing than
admonishing. Still he ceased his rubbing to reach up and press Yuuto’s face
back into the wall. Truthfully this whole play with “rules” and “punishment”
was more for Yuuto’s enjoyment than his own. Yuuto whimpered; immediately he
found himself sorely missing the feeling of Hayato’s experienced hand on his
ass. Unconsciously he arched his back further, angling his hips back to try and
rub up in any way possible against his brother’s leg—or anything he could get
for that matter.
Hayato, feeling generous, obliged, coaxing yuuto’s legs apart with his knee and
kneading lazily at Yuuto’s groin from behind. His full, soft lips were heavenly
against the flushed skin of Yuuto’s neck, his kisses gentle yet possessive as
he worked his way up to the corner of Yuuto’s tightly clenched jaw, burying his
nose in the younger boy’s dark hair with a soft sigh.
“I can barely make out your scent today, probably because of this,” he tugged
at the collar of Yuuto’s t-shirt, which was actually one of Hayato’s—it seemed
he’d stolen it from his older brother’s closet while he’d been away at his dorm
at Hakone. “What’s the meaning behind taking my clothes anyway?”
Yuuto opened his mouth to reply but only a quiet gasp came out as Hayato
suddenly resumed massaging him with his hand, and a bit less mercifully than
before, at that. “I… I missed your smell, too… you were gone at school for a
long time.”
“So you put on my shirt and a pair of some girls’ panties?” Even without seeing
his brother’s face Yuuto could hear the amusement in his voice. It was not a
question that needed answering.
“Aniki,” Yuuto said instead in mild exasperation, “Please touch me more, I’m
gonna go crazy.” 
Hayato only liked to bother with so much teasing before he got to the point--at
least in times like these, in which he felt particularly impatient. It had been
a long time since his last visit home, and even longer since he’d actually been
home all alone, just him and Yuuto… which meant it had been way too long since
they’d last done this.
He reached over to the shelf for a bottle of lotion, squeezing a couple pumps
of it into his hand before unceremoniously yanking the panties to the side with
one finger and smearing it into Yuuto’s ass with the remaining. Lotion would
have to do since he’d left his lube at school. The younger boy shivered from
the coldness of it but Hayato knew that was how he liked it,; he didn’t waste
time letting him adjust to the temperature before sliding in a finger coated
with the rest of the lotion.
“Aniki, it’s cold…”
“You’ll warm up soon,” Hayato mumbled mostly for show—it wasn’t as though this
was the first time; not remotely. He slid in a second finger with more ease
than he was expecting.
“Yuuto.” he breathed, his voice coming out low.
“Mm?” Yuuto panted, trying to fuck himself on his brother’s fingers as best as
he could, but he was in an awkward position, and didn’t feel nearly filled
enough yet.
 “Have you been playing with yourself?”
 Yuuto paused before giving a slow nod, desperately wanting to turn around and
face his brother at a time like this.”I was waiting for you to come home,” he
said earnestly enough. Shinkai scissored his fingers wide inside of Yuuto,
earning a sweet moan.
“You were thinking of me?” he purred, spurred on by Yuuto’s quiet mewls. He
wasn’t old or experienced enough yet to know to hold back his reactions, not
that Hayato had any complaints. Wordlessly he pulled out his fingers and
withdrew his hand, reveling in the snap! of elastic slapping Yuuto’s inner
thigh as the panties went back into place. Before the younger boy had a chance
to protest at the loss of his fingers, Hayato pressed into him again, this time
straight through the panties. The feeling of his brother’s finger pushing the
silky fabric into his ass made Yuuto’s knees wobble as he braced himself
against the wall, even if it was comparatively a little dry.
This was not lost on Hayato however who pumped another generous helping of
lotion into his hand and smeared it into the satin. It soaked through the
garment quickly, the fabric puckering, indented where it clung intimately to
the shape of him, even without the pressure of Hayato’s fingers. Yuuto shivered
at the cold, wet feeling between his legs, trying to ignore the overly lewd
squelching of wet fabric and lotion dripping down his thigh as Hayato’s fingers
fucked him through the satin.
“A-Aniki….” he drooled, “quit teasing…”
“It goes in pretty deep, huh…” Hayato remarked mostly to himself, amazed that
he could get his fingers in almost to the knuckle even when encased in satin.
He twisted his fingers a few more times for good measure, burying them as deep
as they could go and enjoying Yuuto’s every little moan and squirm as he did
so. Unconsciously Yuuto lowered one of the hands he was using to brace himself
to stifle his own twitching erection. It was cute, Hayato thought with an ill-
suppressed chuckle, how Yuuto never wanted to come if he wasn’t able to look at
him.
Once he was satisfied he pulled out, peeled the drenched fabric from his little
brother’s ass, and slid it down his thighs. Hayato knelt to roll the panties
down past his ankles and Yuuto wordlessly obediently lifted one leg at a time
to step out of them.
“You said you got these from a girl at school?” Hayato mused, as if only now
registering Yuuto’s earlier words.
Yuuto ignored him to whine, “Aniki, can I turn around now?”
“In just a minute, I’m admiring the view.” He was kneeling at the floor now,
his half-lidded gaze taking in the sight of Yuuto’s ass from this angle, still
slick with lotion. He palmed lazily at his own groin but did not seem to be in
any hurry.
“Yeah, I did,” Yuuto breathed into the wall in answer. He was feeling empty and
impatient.
Hayato unrolled the (now possibly ruined) panties and held them up to admire
the ribbons and lace, “...It surprises me that a middle school girl would own
something so sexy…”
“We’re in our third year already, aniki, people are already interested in this
kind of thing.” Yuuto gave a weak shrug. “Please can I turn around?”
“Okay, you’ve been good.” Hayato caressed the back of Yuuto’s leg, placing a
tender kiss in the inside of his knee before shifting back so Yuuto could
finally face him. What a sight that was—his cheeks flushed, lips pink from
biting them in a futile attempt to contain his voice. There was a damp spot at
the base of his baggy shirt where it tented over Yuuto’s barely-attended
erection. Hayato let out a slow, heavy breath and leaned back on his palms.
He’d missed his brother more than he thought.
Yuuto peered down at him with a desperate, glazed over look in his eyes.
"I wanna kiss," he said with the same shyness he might have had asking to share
his brother's bed despite now being "too old".
"Okay," Hayato said with a chuckle, his voice was laden somewhat with arousal
but mostly just brimming with fondness for his brother. He rose languidly to
his feet and moved back to sit himself on his bed, scooting back just enough to
make room for Yuuto. He patted the blanket in a motion for the boy to join him
and Yuuto obediently crawled onto the mattress, perching before him in a
kneeling position.
"I missed you, Yuuto," Hayato whispered fondly, leaning up to press their
foreheads together before their lips met.
The way Yuuto kissed could only be described as erotic—even if it was only that
way unintentionally. His mouth was wet and needy and he could never keep up
with his brother's pace, leaving him breathless and sloppy. Hayato had
definitely had—and would surely go on to have—better kisses in his life, and he
wouldn't exactly say sloppy kissing was his favorite kind. But everything Yuuto
did was sexy in his eyes. For better or for worse, he loved his messy, eager
little brother.
He raked his hands up Yuuto’s sides, thumbing over the boy’s nipples through
his shirt before lowering to rest on his hips. Slowly he coaxed Yuuto out of
his overly formal sitting position, the word relax… falling off his lips in a
dark, sweet laugh. Yuuto’s calves slid tentatively out from underneath him as
he sank into the mattress with a sudden shyness. For all that he’d insisted on
facing him, Yuuto was much milder face to face, melted and mollified by his
older brother’s affection. It made Hayato’s heart clench and he couldn’t
refrain from placing the lightest kisses over Yuuto’s fluttering, hooded eyes.
“Hayato…” Yuuto murmured, uttering his brother’s name at last. He looked up at
last to meet him with a heavy, needy expression.
Wordlessly he got up on his knees again, crawling forward to tug at the
waistband of his brother’s pants. He dutifully retrieved his brother’s cock,
taking a moment to play with it, smear the precome that had been building up
over the tip down along the length of it. He honestly was very tempted to put
in his mouth, but the thought still made him nervous as he’d only done it one
or two times and was out of practice. More importantly he was out of patience.
Yuuto pushed Hayato onto his back.
Hayato held his breath, “...Yuuto.”
Yuuto looked so beautiful hunched over him, clearly spilling over with wanting
as he lowered himself onto his brother’s cock. Hayato reached up to help steady
him, almost alarmed at the firmness of his younger brother’s arm as his fingers
failed to close a circle completely around it.
He knew this was trouble.
Yuuto was growing up, and without ever having to speak about it they had
reached the point where they were both old enough to know exactly what the they
were doing—and that this was probably the last time, or among the last, that
they could do it. Hayato would be eighteen soon, and a legal adult, and that
would make doing this kind of thing with his very not legal brother off-limits.
God, nevermind that they were brothers. He could have laughed in disgust at
himself had he not been blissfully literally ass-deep in Yuuto at that moment.
Yuuto—who was eagerly fucking himself on his brother’s cock, moaning in a low
voice and probably thinking all the same things he was. Or maybe he wasn’t
thinking about it at all, which only made it that much worse. Hayato wondered
how things had gotten so fucked up. It had honestly all started as simple
curiosity, a natural occurrence with the onset of puberty...harmless
experimenting—back when they honestly hadn’t known any better. But after a
certain point it had gotten too addicting for the both of them.
Oh well—if it had to end, he may as well make it count. Yuuto certainly was.
And boy, was he a vision.
“You’re so sexy,” Hayato breathed, pulled out of his thoughts by the sight of
Yuuto’s flushed, naked body as the younger teen ripped the shirt over his head,
using it to wipe away some sweat before casting it to the floor, forgotten.
“You’re so cute. I want to spoil you forever.” Hayato was practically gushing
over him, only half-coherent at this point; Yuuto was riding him hard.
“Do it.” Yuuto begged. It was empty banter at this point but with the way he
whined he may as well have been serious. He yelped suddenly as Hayato actively
thrust into him for the first time since they’d started fucking, having let
Yuuto do the work up until now. The dark haired boy lurched forward, twisting
his fists into the sheets on either side of Hayato’s head, looking down at him
with helpless, misty eyes. Hayato thrust up again, harder. Yuuto wailed. “I
wanna come!”
“You can,” Hayato smiled gently, though the words were half caught in his
throat with a deep groan he didn’t bother trying to stifle. He raised a shaky
hand to thumb affectionately at Yuuto’s cheek, “be a good boy and come for your
Aniki.”
Yuuto nodded and gave into his orgasm, Hayato coming not a moment later.
“Aniki,” he sighed, practically collapsing on top of him and not really caring
for the moment how sticky he was. “....that was the best.”
Hayato felt his heart squeeze again and knew that he was doomed. Maybe one or
two more times wouldn’t hurt...
