Chapter Summary
     Shiro's been working hard on his studies. His little sister thinks he
     deserves a reward. Illya X Shiro
Chapter Notes
See the end of the chapter for notes
It was a perfectly ordinary day. The sun was shining, the birds were singing,
Luvia was being dragged off to jail for violating child labor laws as Rin
gloated for having made the call that busted her, Ruby had Sapphire's thumb
drive inserted into her usb port as the two had crazy magic wand sex, and Emiya
Shiro was using the family dining room table to study. Sella was off doing the
groceries and had dragged Leysritt away to accompany her, annoyed at the other
maid just watching magical girl anime.
He'd just finished the last of his homework and was wondering if he had time to
do some reviewing for the college entrance exams (they were two years away but
he wanted to be ready!), when he felt something on his crotch, as it a cat or
small rodent had suddenly run over it. He gave a sudden yelp, his chair sliding
back with a loud squeel as he pushed back from the table. The table gave a loud
thump, as if something had slammed on the wooden surface from beneath.
His chair hadn't slid back very far, but it was just enough for Shiro to see
Illya between his legs, kneeling under the table and rubbing the top of her
head, an annoyed look on her milky white face. "I-Illya?" he stuttered. "What
are you doing under there?"
Illya gave him an annoyed look and bumped into the table again. "Ow," she
muttered. "Oniichan! What did you do that for? I hurt myself under here!"
"Sorry!" Shiro asked. "I didn't know it was you! But... what ARE you doing
under there?"
Illya pouted looking to one side. "Well, you were studying pretty hard, so I
thought I'd be a good little sister and congratulate you on how hard you've
been working."
"Oh!" Shiro sighed. So it hadn't been a rat. "Well, thank you Illya-chan, but
why are you under the table?"
The little face looking up at him from the space between the bottom of the
table and his crotch gave him a float look, and then two small, pale arms slid
up over his thighs. Before he could do more than shudder at the sudden
sensation, one hand had grabbed hold of his waistband while the other grabbed
his zipper and tugged. It slid about a centimeter before getting stuck.
"Stupid zipper," his sister muttered, struggling to pull it down the whole way
as Shiro gave another surprised yelp, trying to stand. The table thumped again
as illya hit the top of her head on it a third time, but he fell back on to his
chair, her grip on his waistband keeping him in place. Fortunately, the fabric
of his school pants was relatively soft, and she managed to pull down the
zipper, revealing the fabric bump of his crotch that was slowly bulging at all
the stimulus to the surrounding region.
"I-Illya..." he protested, then shuddered against as she clumsily tugged on the
fabric, the pressure of her small hand resting on his dick as tried to pull
down his underwear. At last she managed to get to the elastic, pulling it under
his balls with a final tug, and his cock finally flopped out onto Illya's
knuckles with a burst of musky scent, not quite flaccid and slowly coming to
attention. "What are you...?"
"Isn't it obvious, oniichan?" Illya said, not relinquishing her hold on his
waistband as she properly gripped the rising organ with her free hand,
squeezing the shaft as if to gauge its firmness as it continued to stiffen.
"Wow, you really need more porn. Though after this," she said, kissing his tip
and causing his dick to twitch, "you're probably not going to need it anymore."
And with those final words, she took his dick into her mouth, opening wide to
let his girth fit through her soft, pouty lips.
Shiro wanted to yelp, but he only managed to let out an involuntary groan even
as he tried to get up. There was another thump on the table and a small,
annoyed fist struck his hip reprovingly even as small lips went back and forth
along his dick, Illya's inexperienced tongue lashing about randomly. One of her
hands reached around, pushing itself between the chair and his as and trying to
pull him forward as it fondled his cheek, while the other arm was wrapped
around his knee, pulling his leg against Illya's body.
The elder Emiya could only lean forward and rest his head on the edge of the
table as he sat tensely on his chair, eyes opening and closing as he felt his
little sister sucking inexpertly but enthusiastically on his cock, occasionally
thumping his fist on the table. It wasn't long before he came jerkily into
Illya's mouth, the release sudden and without warning. Illya slowed her pace,
pulling out as far as she could without letting him go as she let him
ejaculate, her tongue licking over his tip to as she sucked on him like a
straw.
"Owii-chawn!" her slightly muffled called out as he felt her lips relinquish
his cock. Groggily, he opened his eyes and sat up, peering down. Between his
legs, one arms still wrapped around his knee and her other hand holding his
dick, Illya smiled and showed him her open mouth, the faintest glimpse of
something white on her tongue before she visibly swallowed. Shiro's dick
twitched again as Illya smiled widely, and her hand began to stroke his dick
again, sliding along the now-lubricated surface.
"Come on, onii-chan," she purred, pushing up from between his legs, her arms
leting go of his knee and reaching up to his shoulder to pull herself up.
"You're imouto isn't finished yet..."
She was still wearing her school uniform, a distant part of him noted as she
climbed up, his dick rubbing against her. One warm, smooth thigh pressed
against it as she got to her feet, and it scraped down her leg as she pushed
herself up to sit on the edge of the table. "O-ni-i-cha-an," she crooned as she
raised her other leg , heel balanced on the table's edge as his tip ruubed
against her knee, feeling like it jerked upright with every pounding heartbeat.
Her short skirt had already slipped down almost to her hip at the pose, was
casually pulled to one side, revealing her bare, downy crotch.
Illya leaned forward and put one arm over Shiro's shoulders, massaging his neck
as she licked the the finger of one hand and stroked it against his face,
making sure she had his attention before letting it drift downwards to her
cunt. With a slightly exaggerated moan, she began to finger herself, letting
her finger rub back and forth across her folds. One finger was soon joined by
another as she rubbed her knee against his crotch, keeping his cock stoked and
stiff. Her thumb began to rub over her clit, and with less exagerated and more
enthusiastic groan, she reached up with both hands, pulling him towards her as
her knee tried to get under his groin and pull it upwards.
Shiro needed little prodding, going with the flow now. He fell over her as she
leaned back to rest on the table, one of her hands tugging the skirt up and out
of the way as Shiro got to his feet, his dick blindly scraping against the
inside of one of her thighs as he rocked his hips back and forth instinctively.
With one hand, Illya grasped around downward, feeling the dick against her
thing and rubbing against the crease between her leg and groin. She took the
errant organ in hand as she curled her legs back and clumsily guided the tip of
Shiro's cock towards her cunt.
Shiro felt the unfamiliar opening, his hips blindly pushing forward as Illya
let out a moan. "S-so... big..." she gasped, wincing in pain as it made its way
inward. Her legs kicked to the sides in a futile attempt to relieve the sudden
ache as Shiro pumped into her, falling on animal instincts as he fucked Illya.
His dick drove back and forth as her pussy tightened spasmodically, the member
slowly hardening again as he recovered from his first orgasm.
Illya panted as Shiro rode her, her breath going in and out almost as quickly
as he was and she shuddered, tightening suddenly. He didn't even notice as she
came for the first time, only knowing her tight pussy became even tighter as it
squeezed him hard on all sides, her legs curling limp and rubbing against his
sides.
Shiro groaned as he came again, his eruption unceremonious, squirting much less
into Illya than before as he pushed deep into her, her bare legs and ass
grinding against the course, moistened fabric of his school pants. Her cunt
squeezed around him as his dick throbbed in regular rhythm, squeezing the cum
out. His muscles gave out on him, and he all but collapsed on top of her
panting.
Gritting her teeth and with a firm push, Illya managed to push Shiro's torso
over across the table, her older brother weakly going with the movement to
assist her. She rolled after him, his dick still firmly in her pussy, and it
was either let his dick slip out or roll the rest of the way, and he knew what
he wanted to do. His legs followed to let her sit astride his hips, her slight
but full weight pushing his dick as deep into her as it would go as one of his
ankles bumped against the chair he'd been sitting on. Most of his schoolbooks
hand scattered on the floor, except for a notebook whose spine dug into one ass
cheek.
Illya's eyes were half-lidded as her pussy squeezed on his cock, making it
throb incrementally in response. "Oniiii-chan..." she moaned as she slowly
began rocking gently on his cock once more, crossing her arms to grip the hem
of her school blouse and pulling it up and over her head in one practiced
movement, hampered slightly by one arm being caught before she managed to pull
it off the whole way. Illya sat on his lap, her dark, slightly wet skirt
concealing the way he was shoved hip deep into her cunt and moving with every
slight rise and fall she made as she constantly reminded him they were joined.
Her chest rose and fell with every panting breath, smoothly rounded but for the
faintest of curves, a narrowing at her waist, a subtle bump to delineate her
breasts, the small nubs of her nipples.
Her silvery hair was tangled and wild, swaying to her every movement as it
became her turn to ride him, resting her forearms on his chest like a cat as
her ass bounced up and down on his hips, slowly calling more stiffness back to
his cock as moaned, her pussy squeezing around it as she drove herself more
than him once more. Her knees suddenly squeezed at his sides as she let out a
cry, and he felt a strong, lingering squeeze on his dick as Illya shuddered and
something wet seemed to spread around his cock, dripping onto his hips.
With a satisfied sigh, Illya leaned forward to rest her head on Shiro's chest,
rubbing the top of her head against his chin. "Kiss it," she murmured.
It took a while for Shiro to articulate a response. "W-wha-?" he managed
She looked up at him and pouted angrily. "You made me bump my head on the table
because you kept squirming around," she said matter-of-factly. "Kiss it to make
it get better."
Shiro hesitated, aware he still had his now once more upright but not every
enthusiastic dick lodged up her cunt, still throbbing occasionally. Putting one
hand gently on her head, he parted her hair where he surmised she'd struck it
under the table and gave it a chaste, brotherly kiss. His dick, on its own
volition, chose that moment to ejaculate weakly one last time, squeezing out
perhaps a drop or two before slowly shrinking, becoming less squeezed in.
"Congratulations on your hard work, Shiro-niichan," Illya said, closing her
eyes as her cunt gave him one last squeeze...
===============================================================================

Kuro considered that final ellipse before shrugging. Editing could come later.
"What do you think?" she asked her listeners as she closed her notebook.
Miyu had a wide-eyed, deep crimson expression that was utterly blank.
Illya, predictably, was in apoplectic fury.
"Kuro, you pervert!" she cried as she reached for Ruby.
Explosions rocked the house.

Chapter Summary
     Vita wakes up horny. Vita imposes self-discipline and doesn't go all
     the way. Hayate convinces her otherwise. Hayate X Vita
Chapter Notes
See the end of the chapter for notes
Vita woke up from troubled dreams to find herself not a giant cockroach, her
pajama top unbuttoned and opened, and Hayate's head against her chest, the
Queen of the Night Sky's hair tickling her nipples under the blanket. She
stiffened a moment, foggy memories of former, near-forgotten masters taking her
against her will a looming specter in her mind before she relaxed, more recent
and real recollections of peaceful days overwhelming them. This wasn't the
first time she found herself waking like this, which was a bit disquieting.
She'd wake at the slightest sound from downstairs but never notice it when
Hayate ended up tangled against her.

Vita just lay there, enjoying the guilty feeling of Hayate on her bare chest,
every breath blowing across bare skin and causing her nipples to be tickled by
Hayate's hair as one hand drifted down to slide into her bottoms and lightly,
almost absently, begin stroking her crotch through her panties. She repressed a
shudder, not wanting to disturb her companion. The girl she loved.

It wasn't an uncommon feeling. Signum loved Hayate too. So did Shamal, and
Zafira, and especially Reinforce, who she'd freed and whose presence nagged
something in the very, very old wisps of memories in the back of Vita's head,
but would never be nailed down to exactly what. Loving Hayate felt as natural
as breathing, and if there was lust mixed into it, well... she loved her fellow
Wolkenritter too, and there was certainly a fair amount of lust there as well.
Being the only ones she could depend on to be with all these years, stoicism
had long since melted into unspoken understanding and acceptance.

Vita became conscious of the fact she was breathing heavily, her legs tight and
tense as her fingers rubbed circularly around her pussy through her slightly
wet panties. For a moment, she debated just lying back and continue on, letting
it send her to a small and mildly satisfying climax. Just lie back and keep
doing this until her body kind of gave a shrug and had a small orgasm, as if to
get it all over with.

But no. Even that might disturb Hayate. She sighed and reluctantly willed her
fingers to stop, just letting them rest on her groin as she let herself get
back under control, for her limbs to relax and her breathing to smoothen out.
She permitted herself a smile of satisfaction, tinged even as it was with
disappointment. Her desires weren't going to get the better of her, no sirree.
So what if she was eternally in the cusp of begining adolescence and puberty?
She'd been there most of her life and had long since learned to cope.

Small, quick, mischievous fingers darted under her bottom, dancing over her
still fingers and reaching down to clumsily resume where she'd left off as she
gave a sudden start.

"Why'd you stop?" Hayate asked, her head not moving from Vita' chest even as it
shifted slightly, one cheek nuzzling just under her sternum. Her fingers rubbed
an unfamiliar pattern on Vita's wet spot as her other hand, folded up between
her and Vita's body, began tracing lazy circles on Vita's side. "It seemed like
you were enjoying it..."

"H-Hayate?" Vita stuttered even as Hayate's probing fingers brushed a bit too
hard somewhere sensitive, and Vita gave an involuntary start. "W-what are you
doing?"

"Making you cum, silly," Hayate said, finally raising her head to look up at
Vita's face, her weight suddenly seeming more real as it pressed down on
redhead's body. There was mischief in her eyes as she suddenly blew on one of
Vita's exposed nipples, and the knight's legs twitched at the sudden sensation.
"What does it look like I'm doing?"

"H-Hayate-chan, you shouldn't do this," Vita stuttered, knowing she should be
getting up and gently but firmly pushing Hayate away, and especially getting
the other girl's hand off her crotch. You know, the resposible thing. But the
responsible thing was so very hard to do when you just wanted to lie back and
let things happen. Still, Vita persevered, managing to get herself to say, "Y-
you're too young for this sort of thing, i-it's not decent...!"

"Tough talk from someone who was masturbating with a little girl next to them,"
Hayate said, and Vita couldn't help the mild sting of guilt as the words stuck.
Vita's legs suddenly tensed as, with a sudden gush, her body sort of shrugged
and had a mild orgasm, her legs twitching as the wet spot Hayate had
inelegantly been groping at got wetter still.

There was pressure on her groin as Hayate indelicately pushed up from it, her
still mostly paralyzed legs shifting and sliding limply as she raised her head
to be level with Vita's. "Did you like that?" Hayate asked impishly with just
the hint of salf-satisfaction.

"It was... Hayate..." Vita tried to protest, fumbling to find her hand to get
it away from her pussy, but it was so very hard to do what you didn't want to.

"Vita-chan," Hayate said, interrupting her, "am I raping you?"

The sudden question made Vita go still, shocked. "W-what?" she said, her mind
clearing as she focused.

"In a moment, I'm going to kiss you, Vita-chan," Hayate said. "Then I'm going
to start touching you again. And then I'll rub myself against you. And then
I'll lick your nipples. And then, if i still have the energy and you're willing
to help me get into position, I'm going to lick your hairless pussy until you
cum all over my face. When I do all that... will it be rape?"

Vita's eyes had gone wide at the matter-of-fact litany, almost a checklist. "H-
Hayate-chan..."

Hayate raised a hand where Vita could see it, and the knight fell silent. She
watched, mesmerized, as Hayate rested it lightly on her chest, the thumb moving
slowly circles around her nipple. "Am I raping you, Vita-chan?" Hayate
repeated, and Vita could feel the breath of those words on her face.

"N-no," she managed to whisper.

Hayate let her head dip down and kissed her. Her hand drifted back down Vita's
hip, partially tugging down her pajama bottoms and panties down one hip as the
blanket covering them seemed to grow warmer, almost unbearably so. Her pussy,
now partially exposed, scraped against Hayate's own bottoms before clumsy
fingers found it again, and Vita moaned into Hayate's mouth, her own hand
coming to rest on top of Hayates trying to guide her inexperienced master.
Vita's other hand rose, a bit number from Hayate lying on top of it, and
hesitantly, awkwardly cupped Hayate's ass.

Vita didn't know how long they lay there, kissing without poise or elegance or
inhibition, not caring as long as their lips met, again and again, with
Hayate's tongue clumsily probing into Vita's mouth. The knight tried to reply,
tried to be more than a lazy sloth on her back as Hayate moved her whole body
back and forth to rub herself against Vita's hip, one finger awkwardly poking
in and out of Vita's wet, hot cunt. But she was too hesitant of moving Hayate,
unsure of how delicate she was compared to herself, and truth be told she
exulted at the attentions her master was bestowing on her, at the inexperienced
but sincere wish to pleasure her. No, to make love to her.

Vita came, once, twice, more. They weren't the most intense sensations she had
ever felt, but she treasured them, for the were made by Hayate, given her by
Hayate. Her legs trembled only a little, her body sweating more from the heat
of the blanket on top of them than from any virtuoso performance on her cunt,
but still it felt sweet, so, SO sweet. She lay there and basked as Hayate
inserted fingers into her for the first time, and they were one, and for as
long as she lived she would swear that night was the best sex of her life.

And eventually, as Hayate pulled her fingers out of her, and she pulled herself
up, her warm ass sliding on the sweaty bed sheet, to lie against the headboard,
shivering as her nipples became exposed to the suddenly cooler air outside the
blanket, she felt Hayate's lips on her cunt, her fumbling, inexperienced tongue
now delicately, now clumsily in her hole, Vita came in her master's mouth.

Hayate insisted Vita pull her up with arms that now felt so weak, weaker than
after any battle, and her master kissed her again. Vita could taste the
familiar flavor of herself on Hayate's lips. She'd tasted in before, on Signum,
on Shamal, on Zafira, and recently on Reinforce, but now it never tasted
sweeter, the salty, organic tang shared with Hayate.

She parted from her master's lip reluctantly as Hayate made her lie back on the
headboard, the shorter-haired girl leaning her head on Vita's shoulder.

"Tomorrow," Hayate whispered into Vita's ear, "my turn."

Vita nodded, or tried to at least, failed, then gave it up as a lost cause and
kissed Hayate again. Everything tasted sweeter.
===============================================================================
Kuro finished her recital, smiling widely at Vita's mortified expression as
Hayate clapped happily. "Well?" she asked.

"Bravo!" Hayate cheered. "That's exactly how it happened! Thank you!"

Kuro handed her fellow pervert the novelization. "You're welcome. Invite some
time, okay?"

"I'll think about it," Hayate said noncommittally. "Vita-chan, don't you have
anything to say to Kuro-chan for working so hard to preserve our first time for
posterity?"

Vita hefted her hammer. "Die," she growled in both anger and embarrassment, as
Kuro shrugged and ran.
