Summary
     Ritsu has a nightmare that Rei isn't there, and Rei has to prove that
     he isn't leaving.
Notes
See the end of the work for notes
Rei realizes something is wrong immediately. The house should be silent; their
parents are on an overseas trip again, and Ritsu is always asleep in the still
hours between night and dawn, ready to try and avoid the entirety of the day.
It’s too early for Mao to be here, trying to wake Ritsu up; it’s still a few
hours to sunrise, and the darkness should be peaceful.
Instead, Rei’s bedroom door opens to display Ritsu, paler than usual and
hunched over in his pajamas.
“Oniichan,” he starts, and Rei’s heart seizes up in his chest, because he’d die
a thousand times to hear Ritsu call him that under normal circumstances, but he
knows Ritsu is doing it right now for all the wrong reasons. “I’m staying with
you.” That said, he starts to shuffle over to Rei, but he doesn’t make it more
than a step before Rei is a whirlwind of movement, flinging himself upright to
wrap around Ritsu until Ritsu is all he can feel in his arms.
“Ritsu, Ritsu, what’s wrong?” Ritsu is colder than usual, cold in his arms, and
the fact that Ritsu is letting him hold him so tightly is just a further
indication that things are catastrophically wrong.
Ritsu huffs out a word – some sort of denial, nothing or it’s not important,
and Rei presses a kiss to the top of Ritsu’s head in response.
“Was it a nightmare?”
Ritsu is quiet, and then starts to pull away, half-heartedly tugging at Rei’s
grip on him.
“Ritsu, you can tell me,” Rei says, letting his grip on Ritsu falter in favor
of cupping Ritsu’s chin in his hands.
“Just let me stay with you.” His voice is thick with sleep and he almost
manages to sound convincingly annoyed with Rei, almost manages to sound like he
does whenever he talks about Rei being a bug under his foot, but his voice
cracks on the last syllable and gives him away.
“Of course,” Rei says, because he could never deny Ritsu anything, much less a
request like that. He doesn’t push again, not yet – he can see how Ritsu is
refusing to make eye contact, see the way his lips are pressed together too-
tightly. The last thing in the world that Rei ever wants to do is hurt Ritsu
again, drive him further away. Rei is overbearing in his love, these days,
stifling and clingy, but he’d rather be pushed away than leave.
Rei steps back, and Ritsu moves with him, an automatic synchronicity that would
be unusual if it was anyone but them. It’s only a few steps to the edge of
Rei’s bed, and he sits on the edge, holding his arms out for Ritsu.
“You can stay as long as you—“ Rei trails off, abruptly, drops the sentence
when Ritsu climbs into his lap, wraps his arms back around Rei, and presses his
face into Rei’s neck, puffs of warm air glancing off sensitive skin.
“You’re so annoying,” Ritsu says, his lips a whisper against Rei’s neck. Rei’s
hands go back up, to wrap around Ritsu. Rei knows he can’t hold on tight enough
to protect Ritsu, these days, but he can still try.
There’s not a response Rei can give to that, under the circumstances -- I know
falls flat and repetitions of I love you aren’t going to help –- so instead he
just slips his hand underneath Ritsu’s nightshirt and presses his hand flat
against his back, fingers slipping over the knots in his spine.
“I’m here,” he says, finally, and combs his other hand through Ritsu’s hair
when he feels hot tears hitting his skin where Ritsu’s head is still buried.
Ritsu’s nails dig in tight enough that Rei thinks the cloth might give. Ritsu
isn’t always the best about minding his strength, especially when it comes to
Rei, but it isn’t as though Rei is going to chastise him now. He could rend him
bloody and Rei would let him, if it would give Ritsu the slightest bit of
comfort.
“I dreamed you weren’t.” Ritsu’s voice is a fierce whisper, quivering and hurt,
and Rei knows that his rage is turned as much to the ghost of his dreams as it
is to Rei himself.
“I’m here,” Rei repeats, drawing his hand down to tilt Ritsu’s head up and look
at him. Ritsu doesn’t let him, at first, stubbornly using his strength to stay
burrowed into Rei’s neck, but Rei is firm and, in the end, still stronger than
his little brother. “Ritsu,” he says, looking into familiar red eyes as Ritsu
tries to blink back tears and only succeeds in making them spill over quicker,
“I’m here.”
“Don’t leave.” Ritsu’s voice cracks again; he sounds too vulnerable, too much
like the child that would crawl into Rei’s bed to hide from monsters in his
closet. Rei’s heart is heavy with the idea that he’s the cause of any of this –
but he made sacrifices and knew what he was doing, and he’ll bear all the pain
of his sins for eternity without complaint. “Don’t leave again.”
“I won’t leave you,” Rei says, and it slips out like it would have before he
left, words rough around the edges, without a trace of Rei’s age or exhaustion.
“I won’t leave you again.” He drags his thumb through the tracks that Ritsu’s
tears leave, leaning forward to press a kiss to Ritsu’s cheek. Ritsu’s eyes
close, eyelashes fluttering against Rei’s skin.
“I love you,” Rei murmurs, his lips still brushing against the high bone of
Ritsu’s cheek. Ritsu’s inhale is shaky, when it comes, and when he opens his
eyes his gaze settles, unwavering, on Rei.
“Prove it, anija,” he says, and it’s a shell of his usual venom, a quick
surrounding of ice that’s already half-melted. Rei would endure a thousand
insults and a million cold looks if it meant Ritsu knew he loved him – but he
can prove it, too. He can feel the tension lessen in Ritsu’s frame just from
holding him, and he can see the way his breathing catches in his chest when Rei
falls back so easily on bad habits.
Who he used to be isn’t nearly as hard to grab ahold of as he pretends it is.
Not when Koga is always around, speaking just the Rei used to; not when it
wasn’t that long ago that Rei would have fought tooth and claw to get what he
wanted –
It feels like turning off a light, like surrounding himself in familiar,
comforting darkness. Rei can fall back into what he once was, and it doesn’t
erase the past, but that doesn’t matter, if the familiarity will give Ritsu
relief.
“How do you want me to prove it?” Rei questions. His tone shifts, turns darker
and ruder. His hands shift, dragging a carefully trimmed nail down the shell of
Ritsu’s ear. He shifts, careful and internal, letting the dark seep into his
old bones and wash away his fatigue.
Ritsu shivers, mouth parted. “Like you always do,” he says, and doesn’t let it
be said in the past tense.
Ritsu leans in, and before he can get to his goal Rei surges up to close the
distance first, presses their lips together and lets his hand to back to brace
Ritsu’s head, to hold on. Ritsu makes a noise – desperate, half a sob and half
pure want – and closes his eyes, digging his nails into the back of Rei’s neck
like he’s trying to convey his urgency.
It’s automatic and easy to bite at Ritsu’s lips, to beg for entrance, to kiss
him harder once he’s allowed. Ritsu is always warm in Rei’s arms and Rei can
always feel his self-control slipping away, being replaced by the pounding of
his heart and the way Ritsu opens to him so easy and pliant. Rei knows that
Ritsu isn’t like this for anyone else – it’s just for him, in those moments
where he’s oniichan instead of anija, when he’s the older brother that can take
what he wants and leave hellfire in his wake.
“Like this?” Rei says, lips still pressed against Ritsu.
“If you stop, I’ll never forgive you.” Ritsu’s eyes are half-lidded when he
shifts his position in Rei’s lap, moving to straddle him properly, raking his
nails hard enough down Rei’s back that he can hear the fabric start to give.
“I won’t stop,” Rei promises, and reaches out to catch his fingers into Ritsu’s
shirt, to pull him back down for a kiss and start the task of exposing more
pale skin for him to touch. Ritsu grinds back down, and if Rei wasn’t hard
before, it’s a state that’s rapidly changing. Ah, he hasn’t done this in so
long, hasn’t had Ritsu like this in so long. It’s no wonder Ritsu dreams of Rei
leaving when it’s been so long since Rei last touched him.
Ritsu’s mouth stays open even when Rei stops kissing him, even when he moves
his way down Ritsu’s throat. He drags his fangs across Ritsu’s skin and hears
the way Ritsu doesn’t quite exhale his name.
“It’s been so long,” Rei says, “I hope you don’t mind me takin’ my time.”
Everything he says falls on Ritsu like rain, and he can see the change. It
takes so much energy to be like this – to run hot and heavy, like Rei is a
wildfire – but it’s for such a good cause that Rei would make the sacrifice a
hundred times over.
He’ll be tired tomorrow. He’s more than awake right now.
“Keep telling me.” It’s an order and a demand as Ritsu leans back in Rei’s
arms, stretches and curves his back in a way that makes Rei want to pin him to
the mattress. “Keep telling me that you love me, that I’m beautiful, that
you’ll never lea—“
Rei cuts him off by doing exactly what he wants: he slides his hands down to
Ritsu’s wrists and stretches him out even longer, careening them both down onto
the bed. Ritsu’s shirt falls open on either side, acting like a picture frame
for his chest, and Rei surges down immediately to wrap his mouth around one of
Ritsu’s nipples. Ritsu moans; he pushes up into the sensation like he can’t get
enough of it, he jerks his wrists in Rei’s hold just to feel Rei bore down
harder, refuse to let Ritsu go.
“I won’t let you go,” Rei says against Ritsu’s skin, because it’s what Ritsu
wants to hear, because it’s the truth. “I’m never lettin’ you go again, Ritsu.”
“Don’t,” Ritsu gasps, biting his lip like it might help him hold onto his
reactions. “Don’t let me go, I’ll hate you if you do—“
It breaks off into another moan, Rei refusing to let Ritsu get an entire
sentence out when the temptation of Ritsu’s body is so tantalizing. He sinks
his fangs down into the skin near Ritsu’s hip, and Ritsu cries out, voice thin
and high and shaking.
It’s only the barest of drinks, but the taste of Ritsu still explodes on Rei’s
tongue like a firework going off. His self-control wavers like it always does,
and he clamps down on it, on the desire to hold Ritsu down and keep drinking
until he’s full. He licks across the wound, watching it seal up as quickly as
it appeared, knowing it’s only adding to Ritsu’s arousal. He’d know it even if
he couldn’t feel the solid line of Ritsu’s cock, couldn’t see it pressing
against his pajamas.
“Give me more,” Ritsu whines, his voice catching on his throat. When Rei
finally lets Ritsu’s wrists go, Ritsu moves his hands into Rei’s hair, grabs
fistfuls and holds on tight like he’s steadying himself.
“You’re beautiful,” Rei says, leaning back up to look into Ritsu’s eyes.
“More,” Ritsu says, nails scraping across Rei’s scalp. “Oniichan—“
If Rei had any remaining self-control, hearing that from Ritsu’s lips does away
with it rather effectively. He doesn’t think there’s anyone in the world that
would turn Ritsu down, when Ritsu calls out for them like that, so close to
begging and being undone.
Rei pushes Ritsu’s pyjama pants down a little more roughly than he intended,
but Ritsu just arcs up into it. His cock is hard and leaking at the tip and Rei
drags one carefully manicured nail up the side just to hear Ritsu hiss, just to
watch his hips jerks.
“I could make you come just like this, couldn’t I?” Rei says, whispering the
words as he slides over Ritsu’s form so that he can free himself from his own
pants.
“I’d hate you,” Ritsu says, voice so breathy it sends a shiver down Rei’s
spine. “I want you inside me. Nothing ever feels as good—“
Rei lets out a hiss, ducking his head again to press a kiss against Ritsu’s
lips. It cuts off Ritsu’s words, cuts off the stream of obscenities coming from
Ritsu’s mouth, but Rei doesn’t care; he can lick the intent of the words off
Ritsu’s lips just as easily as anything else.
Ritsu moans against him, warm and pliant in Rei’s grasp. He moves his hips when
Rei grabs them, and the motion jerks their cocks together with enough sensation
that Ritsu moans into Rei’s mouth.
It’s been some time since Rei last needed to find the lube that he keeps in the
nightstand drawer, but it’s still there, and there’s still enough for him to
use.
“I don’t want your fingers,” Ritsu says. He’s spread out on the bed with his
hair melding into the black sheets, his eyes a bright glow, and Rei leans back
down, presses a sticky hand to the junction of Ritsu’s thigh and brushes kisses
over his collarbones, tender and reverent.
“You wanna feel it tomorrow?” Rei asks. His fangs skim the surface of Ritsu’s
skin, trail along the collarbone. He doesn’t bite down. He wants to save that
for later.
“Yes,” Ritsu breathes, eyes half-lidded and mouth open. His lips are pink and
he’s holding his body so tense, waiting for it.
Part of Rei wants to refuse – to hold Ritsu down and kiss him sweetly, to wrap
his lips around Ritsu’s cock until he comes with a high moan – but he knows
better. He knows what Ritsu wants in this moment is to be held down hard enough
to leave marks, to be fucked hard enough that even his healing speed won’t be
enough to rid him of the ache by the time school starts.
Rei would die for Ritsu. Comparatively, this isn’t much of a sacrifice.
“Hurry,” Ritsu demands, and Rei does, sliding his hand over himself until he’s
slick and then lining himself up with Ritsu’s ass.
“Hold on,” Rei says, a demand instead of a warning, and Ritsu does, wraps his
arms around Rei and hooks his legs up around Rei’s waist.
Ritsu makes a choked noise when Rei starts to press in. It’s a slow, stuttering
noise, a hint of pain and a promise of pleasure. He isn’t half as prepared as
he should be, to accommodate Rei, and Rei almost stops, but Ritsu is pushing
back against him hard enough that stopping wouldn’t even matter. He can feel
Ritsu stretch around him and it feels as good as ever. If it’s overwhelming for
him, it must be unimaginable for Ritsu.
There are tears pinpricking in the corner of Ritsu’s eyes, and he has them
squeezed shut, breathing in little gasps of air.
“You feel so good, Ritsu,” Rei says, a purr of praise that falls so easily.
Falling back on old habits is easier than it should be, and it’s a good thing
he’ll be able to put the demon back to sleep before school, because he can’t
imagine trying to carry on a conversation like this. Not with anyone else.
Ritsu just makes another choked gasp, fingers clenching at Rei’s shoulders so
hard that Rei knows there will be crescent shaped scabs there in no time.
Rei doesn’t give him as much time to recover as he would normally. It’s not
what Ritsu wants, and it’s not what Rei would have done before. Ritsu had
enjoyed it, then, the feeling of being held down and used for Rei’s pleasure –
but they both knew that Rei would protect Ritsu with his life, that Rei would
never hurt him anymore than Ritsu wanted in the moment.
They’d lost that, somewhere along the way; Rei knows it’s his fault, but if
Ritsu wants to pretend for a moment that things are the same as they were…
well. Rei is hardly going to object.
“Oniichan,” Ritsu manages, voice thick. One hand moves, losing its grip,
dragging down Rei’s shoulder with enough strength that Rei can feel the blood
immediately rush to fill in the welts.
Rei doesn’t bother to reply, not with words. A thousand verbal promises don’t
mean anything when compared to this: the rush of arousal, the feeling of blood
pumping through his veins, the sound of every hiccupping gasp that Ritsu makes
as he tries to feel more and less at the same time.
Rei kisses Ritsu again, hard enough that he can feel Ritsu strain to remember
to breathe underneath him, hips jerking. His cock is hard against Rei’s
stomach, but Rei doesn’t reach for it, and Ritsu doesn’t try to take matters
into his own hands.
“You don't even need me touchin' you to come,” Rei says, and punctuates it with
a lick up Ritsu’s neck, a long strip from shoulder to ear then makes Ritsu
whine desperately in the back of his throat. Ritsu tilts his head, baring the
long plane of his throat, an invitation that Rei can’t resist when it’s being
offered so easily. "Just me in you."
“Please,” Ritsu begs, desperate and wanting. Every time Rei moves inside of
him, Ritsu’s hips jerk, meeting each of Rei’s thrusts with as much force as he
can manage.
Rei sinks his teeth into Ritsu’s neck, harder than he has in what feels like
months. They’ve both been drinking from the other since they were small, long
before they knew what they were doing – a transitional step, to feeding off
people. They’ve been lingering in that step for years, because no one tastes as
good to Rei as Ritsu does; the taste of him spills over Rei’s tongue and he
swallows too quickly.
He knows he can’t take much, but it’s hard, when Ritsu cries out, writhing
against him with almost mindless desperation. He bucks his hips, cock gaining
what little friction it can where it’s trapped between them, and Rei pushes in
harder. It’s the frenzied pace that it always becomes, with the taste of Ritsu
in Rei’s mouth and Ritsu wrapped around him and Ritsu’s voice ringing in his
ears.
“C’mon,” Rei says, withdrawing just enough that he can talk, lapping the blood
from Ritsu’s skin. “You don’t even need me to touch you more than this.”
Ritsu doesn’t. Rei knows it’s overstimulating – to be bitten is pleasure on its
own, but it’s almost unbearable, with someone fucking into you. Unbearable in
all the right ways, and Rei bites again, just below the previous one, giving
Ritsu more than one to trace in the mirror later and remember, just like Rei
will the scratches down his back.
“Onii—chan—“ Ritsu stammers as he comes, the title a substitute for all the
things he can’t say. Rei can still hear it in his voice, the words please and
thank you and don’t leave and you promised, and Rei kisses Ritsu to drown out
the sound of them, lets Ritsu lick the taste of his own blood out of Rei’s
mouth.
Rei drags it out just long enough for Ritsu to whine at him. He can manage
that, at least. He waits until Ritsu makes that high, keening noise in his
throat, fingers digging down hard in Rei’s back.
“It hurts—“ Ritsu says, and Rei buries his face in Ritsu’s neck, buries his
cock as deep in Ritsu as he can go, and allows the wave of his orgasm to crest
in shudders over him.
“You’re heavy,” Ritsu says, almost immediately. He’ll bathe in the afterglow
physically, he’ll lay there and let Rei’s cock go soft in him, but he won’t let
Rei have the emotion of it.
Rei probably deserves that, so he doesn’t complain; he just pushes himself up
onto his forearms, shaking faintly from the exertion of everything as he hovers
above Ritsu.
“I’m all gross now,” Ritsu says. He’s still out of breath, still taking in
gulps of air that make his chest rise more than usual. Blood beads at the bite
wounds on his neck, and his lips are so red that Rei isn’t sure they’ll be able
to hide it by the time has to leave for school.
“I’ll take you to the shower,” Rei offers, leaning down and pressing his
forehead to Ritsu’s. Ritsu rolls his hips, hisses at the feeling of Rei still
inside him, but doesn’t shove him away.
“No,” Ritsu says. “You said you’d stay with me. I’m tired.”
“Hm,” Rei says, and thinks back for a second – what would he have done, before?
Ahh, the moment has passed, it’s such a strain to keep reaching for who he was,
but he can manage it for a few seconds longer, with the promise of sleeping
with Ritsu on the horizon.
He reaches out, wraps his arms more securely around Ritsu, and lifts him up.
Ritsu cries out, louder than he likely meant to, and Rei keeps moving, pulls
out of Ritsu and then stands up still holding him.
“Nn—“ Ritsu starts, a complaint and a threat and several things that Rei is
familiar with all starting to form, until Rei places him down in his coffin,
instead. There’s room for two, but only just; it isn’t nearly as comfortable as
the one he has at school, these days, but sacrifices must be made. He uses the
bed more often at home, but he wants to feel the heat of Ritsu’s skin on his as
long as possible.
“You’re gross,” Ritsu says, once the lid of the coffin is over them and they’re
enclosed in darkness. It’s safe and familiar, and he’s close enough that Rei
can feel his eyelashes flutter against Rei’s cheek when he blinks. Rei can
still see him, muted and grey in the darkness.
“I’m here,” Rei says, in response, pressing Ritsu to him. Ritsu heaves a sigh,
mumbles something under his breath – Rei catches the word anija and bug -
- before resting his head on Rei’s shoulder.
“You can be my pillow,” Ritsu says, “all day. And you can get up to tell Maa-
kun that I’m not going to school tomorrow.”
“You really should go to-- ow.” Rei breaks off when he receives a well-placed
elbow to the stomach, cuddling Ritsu even more in response. It’s a bit like
harassing a cat, really. “I’ll tell him.”
“It’s your fault I’m up late,” Ritsu says. “So take responsibility, and stay
with me all day.”
“I will,” Rei says, and promises it like his old self, then repeats it again,
like he talks these days, because it’s true even if he’s tired. “I will. I’ll
stay with you forever.”
In the darkness, Ritsu closes his eyes, but doesn’t let his hand go slack where
it grips Rei’s.
