Fourth Night (2)

"This...isn't going nearly as well as I thought it would."

Shirou made no reply other than a distant grunt, which Illya figured was perfectly understandable, given that she was currently in the process of modifying his soul.

Making use of her newfound abilities with the Third Magic Illya realized simply assuming she could make use of a True Magic as if she'd born with it had been...optimistic. It was like a blind man being gifted sight, making use of a sense she had never known would one day be made available.

Changing and altering the soul was...difficult.

To her expanded perceptions her step-sibling's soul took on the form of a malleable ball of steel in Human form, a sharpened expression of his being that she could flatten, heat or mold into new shapes or formations.

...Except she didn't know what any of these 'shapes' or 'formations' would do to him. Would they cause some kind of irreparable damage to memory or personality? Not do anything at all?

She didn't have the first idea of where to start. And matters weren't helped by the twisting skeins of red that flowed throughout Shirou's body like some kind of sea anemone, invading and altering pieces of his soul in an unstoppable tide.

His ongoing vampirization at work.

Gritting her teeth once more in frustration Illya tried yet again to reduce or remove the slithering tides of crimson invading her Shirou's body, only to be stymied as the infection would simply begin to spread anew, her skill with the Third Magic not nearly comprehensive or skilled enough to simply erase it from existence.

Biting her lip in frustration that she couldn't spare her step-brother the fate of becoming a Dead Apostle the Homunculus did the next best thing she could both think of and actually perform.

Seamlessly integrating Apostle and Human together in a perfectly interwoven tapestry. To her extrasensory gaze the joinings that existed were...imperfect, frayed. Like a ratty rope trying to hold a ship at port during a raging storm. She wasn't sure if it was a sign of rejected vampirization or simply how the process was meant to go...but she was sure as Hell going to fix it right. If she couldn't keep her Shirou from becoming an Apostle then she was going to make damn sure he was the best Vampire that ever was!

Delving into the depths of the Third Magic the Homunculus reached deep into the shifting sea of red at the center of her brother's being, taking note of the imperfections in how it layered itself against the metal structure beneath...and pulled with all of the power at her disposal, a conceptual act akin to yanking on a bit of lace to tighten a loose article of clothing.

Repeating the action along the countless pathways of her brother's spirit Illya eventually reached the outer limits of the vampirization, gathering up the searching strands before properly weaving them into a cohesive and airtight formation befitting a sound soul.

Time lost its meaning, only the hypnotic lull of her craft and desire to turn the man beneath her into nothing short of a work of art to mark the passing of seconds...or maybe it was years?

The only benchmark Illya had was the completion of her task, which she finally achieved after an inestimable eternity, staring at her completed project with a sense of resigned satisfaction.

The soul before her was what a metal mannequin would resemble if one wrapped it in a pulsating web of bloody fabric, countless strands perfectly intertwined over a steel base that hummed with supernatural harmony, like an instrument perfectly tuned or singer flawlessly pitched.

An internal nod left the Homunculus as she removed herself from the higher plane of awareness that accompanied the Third Magic-


-and returned to the mundane world with a roaring headache and aching body, low groan escaping her lips as she collapsed onto the male form beneath her, strength gone and senses haywire.

If this was the result of the Third Magic she could see herself using it sparingly. Hopefully it was simply because she had overtaxed herself during the first usage than it was any kind of consistent side effect...

"Illya?"

"Onii-chan?! Are you awake, are you feeling alright?!"

Weariness and pain forgotten the albino shot upright, swiftly placing her hands on either side of Shirou's head, checking to make sure he was still in one piece-

-and had to blink at the sight that greeted her.

His hair was gray. And not just any gray, but steel grey, shining with an odd luster similar to that of polished metal. Gone were the amber eyes and in their place were glowing orbs of crimson a shade similar to hers, pupils of midnight black gazing at her with an unusual intensity. His skin was still tanned but with an odd tinge to it, as if the blood beneath had simply gone missing.

"I...didn't know altering your soul would also change your appearance, Onii-chan."

"I didn't either."

He slowly sat up, Illya still straddling his lap with a concerned gaze as she checked over every inch of his body to make sure it was intact.

It was with a relived breath that, aside from nails that were black and perhaps a bit sharper than normal, nothing else seemed to have changed.

"How do you feel? Are you thirsty, weak?"

Slowly shaking his head Shirou mildly frowned, replying, "No, I...actually feel strong. Stronger than I've ever felt as a Human. Things are...sharper. My eyes are better, as well as my smell and hearing. I..."

The Homunculus shivered as his gaze once more settled on hers.

"I can hear your heartbeat, Illya. And I guess I'm a...little bit parched."

Not hesitating for even a second the albino used her nail to slice a small, bleeding gash on her neck with a concerned frown, stating, "Onii-chan, you need to drink. You just turned into an Apostle and need blood to function. Take from me, I trust that you won't hurt me."

For a moment she was concerned that her idiot step-brother would refuse or something ridiculous like that...but his eyes wandered onto her slowly dripping wound with a hypnotic fixation, body seemingly moving on instinct as one hand gently pushed aside her hair and grabbed her skull, the other pushing against the small of her back as his mouth parted in a hungry display of want.

The tender but domineering display sent such a barrage of tingling warmth throughout Illya's body that she had to bite back on an audible gasp of arousal. This...this was nice.

Then Shirou's lips closed around the bloody laceration and a giggle of happiness left the Homunculus, the sensation of his tongue caressing the cut and light suction as he fed a potent cocktail that she could see herself coming to enjoy. A lot.

"Shirou, you're acting so needy~."

Just as the Homunculus began to truly enjoy the young man's ministrations, letting her hands wander over sculpted abs down to the hem of her step-sibling's pants...he stopped, pulling away from her with a satisfied lick of his lips, Illya pouting with denied frustration.

"Onii-chan, don't you need more blood than just a few drops? I know newly turned Apostles don't need much but-"

"It's fine, I actually feel quite satisfied. Did you maybe do something when you were altering my soul?"

Pausing to give his words careful consideration Illya found herself briefly wondering if she had indeed done something to stave off most of the Vampiristic traits associated with most Apostles. Maybe so tightly interweaving his Human and Vampire natures had allowed his body to require much lower amounts of blood than usual?

"Well as long as you're not lying to me...then I guess we, erm...just have one last thing to take care of?"

Suddenly feeling both intense arousal and shyness at the same time Illya lowered her head, gazing up at Shirou as he wordlessly nodded, staring out of the nearby window to the tear in reality as it continued to spill its disgusting contents out onto Fuyuki.

They were both fully aware that, given the narrow timeframe they had to work with, a tantric ritual would be the most efficient way of establishing a connection between the two of them.

And Illya had absolutely NO intention of revealing that, given her limited control over something as powerful as the Third Magic, she could simply implant a fragment of her soul within Shirou and allow him to directly partake of her power that way.

This could very well be the last time they saw each other and she wanted it to be memorable, to enjoy the limited time she had with her family.

Swallowing what little nervousness remained the Homunculus swiftly reached out with shaky hands, undoing the clasp on Shirou's pants and working them down his chiseled hips while licking her lips with anticipation-

-before his hands seized hers with a gentle but firm grasp, Illya petulantly glaring at him with thwarted need.

"Time is short, Illya. And while I would like to make this as enjoyable for you as possible...we need to take care of this as quickly. Will you let me lead?"

While miffed that their first time together would be nowhere near as romantic and long lasting as she had hoped it would be...there was a certain excitement to Shirou looming over her, taking charge and telling her to let him take care of...things.

"Ok, Shirou...I'm all yours-mmm~!"

Closing her eyes in bliss as the taller male sealed his lips over hers the Homnculus eagerly leaned into the feeling, of soft skin and hot breath intermixing with her own, a foreign sensation that was...not bad at all.

No, it was great.

Lacing her hands through Shirou's hair Illya responded with considerable enthusiasm, almost squeaking with shock as she felt a slimy, warm tongue prod at the edges of her mouth before she eagerly welcomed it in, nibbling on the muscle as she luxuriated in yet another unknown pleasure.

Which left her all the more disappointed when the young man pulled back, leaving her panting and about to make her displeasure known...when his head dipped, latching onto her breast before one of the strangest and most intense feelings struck the albino like a blow to the gut, a high-pitched mewl leaving her lips before she could stifle it.

"S-Shirou, that feels...really good~!"

Her fingers greedily dug into her sibling's scalp, forcing his head deeper into the slight swelling of her chest as mewls shifted into womanly moans, forceful pressure suddenly assaulting her cherry bud as her lover began to suckle the teat, tongue lapping at the edges as an ever more intimate strain built between her legs, something wet and sticky trickling down her thigh-

-and now it was an open hiss of anger as Shirou pulled away despite her forceful grip, teeth gritted as she growled with all the anger of a surly kitten.

"Shirooouuu...stop teasing me!"

The slightest traces of a smile appeared briefly before he replied, "Sorry, Illya. Just trying to get a feel for your body and responses. We need to climax at the same time for the tantric ritual to work and I'm trying to take the fastest path to it."

The Homunculus blinked.

"Shirou? You kill the mood when you say stuff like that."

The newly turned Apostle seemed genuinely apologetic as he responded, "Sorry...Caren and even Sakura also said I'm not good at intimate talk."

"And talking about other girls when I'm aroused and wet on your lap is even worse!"

"...You're right, sorry."

And with that he removed his pants with zero fanfare, Illya's eyes widening as another bout of nervousness struck.

She...didn't exactly have much experience with other men or knowledge of their anatomy so she had no idea if Shirou was unusually big or simply average...but he looked generous, at least to her eyes. And the memory of the time she had, well...touched it was suddenly at the forefront of her thoughts.

"I...I'm pretty sure I can fit that inside me..."

"Illya?"

"N-nothing! Here, let me help, Shirou!"

Gathering her courage the albino wrapped her soft and newly acquired palms around Shirou's length...and paused, entirely unsure of what she was supposed to do next. Was...was she supposed to pull in it? Or, or even...suck on it?!

"It's fine, Illya. Let me lead."

Blushing furiously at her failed attempt to take charge in the matter the Homunculus weakly nodded, slowly removing her hands from Shirou's rod-

-and a sensation she imagined would be like getting punched by Berserker wracked her body as the odd hybrid of Human and Apostle set his hand between her legs, the fire burning in her loins suddenly stoked.

"S-Shirou, I-Ah~!"

Giving up entirely on keeping herself quiet Illya let loose a passionate cry, the sense of rough skin brushing against her most private area stimulating nerves to a height she didn't even know was possible...especially when Shirou's pointer digit poked at a tiny bundle of said nerves and just like that her eyes had stars and spots of black dancing across them, a silent scream escaping as her body convulsed mindlessly, spine arched to a painful degree with muscles cramping spastically.

It was a fair few seconds before she felt any semblance of rational thought return to her perception.

"You're incredibly sensitive, Illya."

Hazily focusing on her sibling's comment the albino brought herself back to something resembling sense, gazing into the crimson eyes opposite her own...and reached down in between her legs, seized by a complete and utter lack of shame alongside boiling lust.

Delicate fingers spread her folds wide, revealing pulsing pink walls of flesh as needy pants left the young woman, Shirou-for the first time-openly ogling her body as even his self-control began to wane.

"Shirou...hurry up and get inside of me..."

There was no further hesitation or nervousness for either of them, Shirou placing a hand on her back while the other grabbed a leg, placing it over his shoulder as he lined up that delicious looking cock of his with her dripping hole.

"If it hurts let me know, Illya."

Only watching the proceedings with a hungry gaze Illya made no reply, Shirou pushing forward with an unstoppable thrust-

-and a sexy whine left the albino as she felt her walls slowly give way, a lovely soreness piercing through her cunt...and the motion suddenly stopped, Illya snapping out of her haze to stare at Shirou with thwarted betrayal.

"Why did you stop?"

"I...thought you were in pain."

Blushing furiously at how loud she must have been-as well as their compromising yet intimate position-Illya quickly responded, "I wasn't in pain, I was enjoying it!"

"Oh. Sorry."

And then she was back to being impaled by a cock of bewilderingly fantastic feeling, throatily mewling the entire time.

She lost track of the seconds, minutes and what could have easily been hours as she was fucked by her lover, spreading pussy being filled by more and more of Shirou's length-

-and something bulbous struck the end of her tunnel, a mild jolt of bruising pain jarring the albino as she gasped in shock.

Craning her head to look at their combined bodies a silly grin appeared on Illya's features, noting with infinite joy that Shirou's member fit her body perfectly, fully sheathed inside her tiny hole so that he filled every nook and cranny.

And then he began to slowly drag himself out of her burning canal.

Illya buried her head into a borrowed pillow, trying to muffle her passionate screams as it felt like she was being pulled inside out, Shirou's flared head scraping and catching on her ridged canal with sensual eroticism, his withdrawal halted only by her pulsating entrance.

"Illya, are you ready? I should end this soon."

Crestfallen at hearing such a truthful statement but knowing full well that this moment wasn't taking place in a vacuum the Homunculus nodded, bracing herself for the coming explosion of feeling-

-and she would have laughed at herself had she not been to busy moaning in pleasure, thinking she could prepare for this.

It was incredible.

A constant filling and then deflation of her insides, of scraping excitement and ticklish electricity racing up the ridged interior of her walls as Shirou pistoned into her body.

"S-Shirou, y-you, I can't...ooh~!"

The Homunculus abruptly felt their position shift, her rear sticking upwards while her chest laid flat on the bed, the two of them mating like animals as she felt her mind going blank.

"Illya, I'm almost...there. Are you...set?"

Taking a delirious amount of pride in how Shirou sounded so close to the edge because of her body Illya whimpered in confirmation, allowing the pleasure to guide her actions as she began to pulse prana through her body, centering it on where she was being pounded into the mattress as a visible glow began to illuminate the room.

"And...now!"

She could feel Shirou tense, a pulsating wave of heat and passion filling her insides-

-and even as the Homunculus screamed herself raw into the bed, head filling with static she reached outwards and followed the wave of pleasure back to its source, letting the breached walls of their respective souls intertwine with a solidarity that was somehow more intimate than mere physical bonding, pouring every ounce of power and innocent love that she could muster into the connection...and with an exhausted sigh let her body go limp, a final jolt of excitement wracking her exhausted form as Shirou pulled himself from her body before gathering her in a hug, warm fluid dripping from her abused and quivering loins as she sighed in contentment.

"You did wonderful, Illya."

"I could stand to go for another round, Shirou..."

"If only we had the time."

Snickering at his words Illya forced her eyes open and shivering limbs to still, admiring her handiwork with a pleased expression.

All across Shirou's body lines of softly glowing prana pulsed in time with her heartbeat, the albino able to feel the connection between them as her power was shared.

Shared with her protector, brother, lover and last remaining family member.

Planting one final kiss on his lips Illaysviel tiredly sighed, remarking, "Let's make this our last battle, Onii-chan. Or at least the last one for a long time."

"Agreed."

Closing his eyes Shirou raised his hands-

-and in them a collection of blackened armor and red cloth appeared, Illya blinking as she asked, "Onii-chan, I didn't know you could make clothes..."

"Only these ones. They were EMIYA's, they became a part of his persona so I can recreate them easily enough, even alter their size and shape. Here, I don't want you to go into battle naked."

Unable to stop the teasing comment Illya asked, "Oh~? Worried other boy's will see what only you and a few others have?"

"Yes, actually."

Shaking her head at the blunt answer the Homunculus donned the clothing, admiring the quality of the ensemble. Armored plates that covered her chest and navel while combat boots and the cloak protected the rest of her body, as light as air and just as cool.

Shirou had also copied his own variety of his alter ego's choice of uniform, the red seeming all the more fitting with his eyes shifted into those of an Apostle's.

They shared a single nod and marched out of the bedroom-

-only for Illya to snicker at Sella, the Homunculus crouched in a corner of the room with a beet red face and hands clasped over her ears.

"T-to think Milady was so advanced...I am just a mere maid and shouldn't be jealous, but to think she found a partner even before I did..."

"I'm sure Onii-chan wouldn't mind showing you a bit of affection as well, Sella~!"

The maid Homunculus leaped halfway to the ceiling, yelping in fright before whirling around to face them.

"M-M-Milady?! I-ignore everything I just said, I didn't-"

A soft glow of released prana caused the Homunculus to cease her hasty explanations, eyes widening as surprise as Illya healed the last vestiges of injury to her leg, the smaller woman grasping the maid's hands with a serious expression.

"I need you to focus, Sella...and will you help me in this battle?"

The question seemed to center the other artificial human, her gaze hardening as she resolutely nodded.

"Of course, Milady...now and forever."

"Good. Berserker!"

The hulking Servant materialized with a low growl, gathering up both Homunculi in his powerful arms.

"Onii-chan?"

"Yes, Illya?"

Both shared a meaningful stare...and settled for a nod that said it all.

"I'll see you soon."

"Likewise."

And with that the Servant was sprinting towards the sounds of distant battle, leaving Shirou to stare after their swiftly shrinking forms...and give a small shake of his head, turning towards the distantly circling airship of gold.

He had his own battle to see through.


Don't you just hate it when sexy time is interrupted by the end of the world?

Seriously, cockblocked by the apocalypse.
