Summary
     Ayato tries to prove he doesn't care about her anymore. Really.
Notes
     cross-post on tumblr. takes place during s1 when ayato and crew
     kidnap ken. really appreciate any and all comments!
When his underlings and Yomuri made their escape with that ridiculous Kaneki
fellow in a bag, Ayato told them that he had some personal business to take
care of, glancing at his sister, and that he’d be back at headquarters soon.
Ayato stared down at Touka, nearly unconscious on the floor, and briefly
wondered if in the years that he’d left her, his beloved aneki had found a
lover or even a boyfriend. Did he care? Surely, he didn’t.
So he wasn’t sure what to make of his actions when he callously hauled her to
her feet, after convincing himself that he didn’t care if there was already
someone who had the pleasure of fucking his sister yet.
He stared down at the face that resembled his own, while she gathered her
bearings. How funny, he pondered. When he left, he’d barely been eye-level with
his sister, but now he easily towered over her. He carded nimble fingers
through her matted hair, which very well could have been shorter than his own.
“Still a tomboy, aneki?” he murmured, trying to sound condescending enough to
assure her and himself that there was no affection, none at all, seeping into
his voice.
“What do you care?” Touka glared up at her younger brother, but there was no
true bite to her words, like always. Never, not for Ayato.
He smirked, his eyes lidded in that perpetual way of his. “You’re right. I
don’t.”
And he chanted to himself, don’t care don’t care don’t care I don’t care, even
as he swooped down and crushed his lips against hers. It was all teeth and
searing heat and he was fighting her with his mouth and neither of them were
surprised when she rose to the challenge and fought back, even in the state she
was in.
He had her pressed firmly against walls smeared with blood; some of it her own,
and none of it his.
When they parted abruptly, he found her eyes roaming over his face. He inhaled
deeply, the pungent aroma of gore lacing every breath.
“You’ve grown a lot, Ayato,” she whispered, sounding almost soft.
He scoffed. Was that really all she had to say?
Touka narrowed her eyes up at him, after observing his outfit, and gave a smirk
that was all too familiar. “But, are you still trying to prove something with
this?” She reached up with a hand to tug at his earring. He also didn’t miss
the lingering, almost amused glances over his black hoodie and ripped jeans.
He minutely winced at the abuse on his piercing and in response, he grabbed her
hand to slam against the wall. “You’re such an idiot, aneki.” And he didn’t
want to hear her talk anymore so he continued kissing her, hard enough that her
lips would bruise with his tongue battling hers, all the while pressing his
hard body into her softer frame.
He was so much more muscular than she’d remembered. In the back of her mind,
Touka yearned for her old brother again—the one who was scared of bugs and
swore to protect her and to listen to her. But, she acquiesced, with her one
free hand braced against his now broad shoulder as he impetuously grabbed at
her hips, that she still loved this new brother of hers all the same because he
was still Ayato.
“We’re both idiots,” Touka managed to murmur in response when he suddenly
leaned back, panting raggedly.
He didn’t respond verbally, instead violently pulling a chunk of her hair so
that her head tilted back. Ayato left open-mouthed, wet kisses all over her
neck, making his way down to her collarbone. When his lips found resistance in
the form of an innocent collared shirt, he tore it open to suck harshly on her
bare skin, just above her heart. Pushing aside her bra, he moved to greedily
suckle on her pert nipple while his hand roughly teased her other breast.
Touka’s hand left his shoulder to grasp at his wild tresses. “Your hair is so
long,” she commented breathlessly, while her eyes remained closed. “But still
so messy.”
How could he tell her he wanted her to shut the fuck up? He stretched his mouth
wide and bit down harshly onto her shoulder and she shouted in surprise.
Feeling his sister’s warm body all within his grasp, and her sweet blood
filling his mouth, and her scent invading his nose made him lose all sense of
rationality.
His long fingers made quick work of the tights covering her thighs, tearing
them to shreds, after rucking her stupid uniform skirt up around her waist.
Ayato pushed his own jeans down past his ass and without even checking to see
if his aneki was ready for him, he forcibly lifted her leg, and thrust his
hips, sheathing his hard length inside her completely and drawing a sharp gasp
from Touka. He choked out a groan at her taut heat enveloping him.
He pondered the irony that even his sister, who was so harsh and cold on the
exterior, had such silky soft inner walls. Touka moaned lowly against his
earlobe and Ayato realized belatedly, through the foggy pleasure overloading
his senses, that he had little resistance when he plunged in her—she’d been
just that wet.
“You’re such a fucking slut, idiot aneki,” he growled against her collarbone,
mostly because he didn’t want to look at her face or he’d lose it. “So wet for
your own brother.”
In response, Touka haphazardly tugged at his messy hair, wrapped her arms
around his shoulders and tightened her leg around his hip. “Shut up, shithead,”
she responded harshly before clamping her teeth on his ear eliciting a low
grunt, while bucking against him.
Ayato wildly pounded into her, building up an unforgiving pace. He lifted his
head ever so slightly to peer into her face—all flushed and sweaty because of
him. “Aneki,” he called out, uncharacteristically softly, just as he bucked
erratically before he came deep within Touka in long, violent spurts.
She shuddered as she felt her own climax sweep through her body, pulsing
through her veins. Touka moaned softly, feeling the warmth fill her.
Panting, the younger brother held her tightly as the two of them rode out their
orgasm. With a few last shallow pumps, he then slipped out of her, his cum
mixing with her own.
Touka expected him to rip away immediately and leave her alone, all over again.
However, after all these years, it seemed Ayato had become insatiable in all
things, including her. Instead, her brother leaned back just enough to spin her
around, pulling her ass towards him causing her to bend forward to grasp at the
wall, and hastily buried himself back inside of her cunt with a low moan. This
time, he slipped in even easier.
He made quick work of her sensitive clit with calloused fingers and rough
friction in and out of her. His hands dug brutally into the flesh of her ass
and her waist while he held her steady through his pounding.
The third time he entered her, he had her back pressed up against the wall
again. He growled lowly against the shell of her ear, “You belong to me,
aneki.” He didn’t even know where the hell it came from, but as soon as he did,
he emptied himself inside of her for the last time. Touka shuddered and keened
loudly with her orgasm peaking and he wasn't sure if she even heard him at all.
Touka whispered, “Ayato,” and he harshly ripped away from her, just as she
expected, leaving both of them very cold and very bare, even with most of their
clothes still on. Touka cried out and leaned back against the wall for support,
knees weak from both the fucking and the battering Ayato had given her earlier.
He stared down at his sister with lidded eyes, only inches away from him—face
flushed, chest heaving, his seed dripping out of her pussy. A frown graced his
swollen lips. Not taking his eyes off her, he slowly zipped himself up, cock
still glistening with a mix of residual semen and his sister's juices. Touka
was only left in her tattered uniform. He turned away to head out the same way
he had come in.
Before he lept out the shattered window, Ayato threw her one last glance and
murmured lowly, “The weak can’t protect anything.”
