Auntie, Mom's a Servant

by Toph the Trickster (TophTheTrickster)

Summary:

Tohsaka Haru was his mother's pride and joy. So much so that she'd decided to try and summon a servant to meet with her son. Except she'd botched the summoning and instead turned herself into the servant.

And Haru, sweet Haru, had to go and arrive at the perfect time to bind the servant to himself instead.

Notes:

It was kind of fun to get to write for Fate after a while. I still want to continue 'of Dragon's Blood' eventually, but I still need my schedule to free up a little more. In the meantime, have this!

This one was an external request. If you guys are looking to have something worked on you guys can find me there:

Chapter 1

Haru was terrified.

It had been a flash of light, the smell of ozone filling the air as he'd peeked into his mother's workshop.

She had been vague about what it was she'd been up to. Only mentioning to him that she'd been working on a special project, one specifically to reward him for how well he'd been doing in his lessons as of late. Of course, she'd told him that he wasn't supposed to peek, and that it had been a surprise for him.

But Haru had been able to feel… something going on. Even several floors above in his room he'd been able to feel the mana passing through the house. Being drawn down and down into the basement here his mother usually did her work. There had been enough of it that he could practically taste it in the air.

Which was what made him decide to come down and investigate. That was a lot of power that his mother was channeling. More power than he'd ever felt her channel before, even more than when he'd see her practice casting her Gandr.

And Haru knew how much damage Gandr could do. He'd spooked her when she'd been practicing once, and it had caused the shot to go long.

It was fortunate that they lived so far from everyone else. Haru didn't know how he was supposed to explain to any neighbors they might have had that he'd accidentally gotten his mom blast down part of their fence wall.

He found his mom's workshop door open and a pale-blue light coming from between the gap.

That was when he found her.

"Mom?"

She was backlit by the glow of the fading runes behind her. Vaguely, Haru noticed that they likely would have been painted unto the stone floor of his mother's workshop, but whatever it was that she'd done had left imprints on the granite.

Marks that were rich in magic, enough so that Haru could feel it from here. Taste it. Maybe even reach out for it with an outstretched hand. A thought.

He felt it before he saw it. Mana. It reached out to him the way he thought of reaching for the mana of the fading circle. And it was familiar, too. Something in the back of Haru's mind heard it whisper to him, felt the sweet taste of it on the tip of his tongue. A tingle in the back of this mind.

The boy reached back.

Something lurched, snapped into place. Vaguely, Haru felt the clanging of chains… somewhere.

Red eyes flashed before him as the door swung open. Two tails of raven hair gazing down at him. Her skin seemed to glow in the little moonlight that made it through the windows of the basement workshop.

Haru paused. Blinking, he realized that it was a lot of skin. A lot, a lot of skin.

Not that he could take his eyes off it. With the way it reflected the moonlight, his golden eyes couldn't help but trace the gentle slope of her hips - something he'd only ever gotten glimpses of when she wore her sleeping clothes - and the curve of her plump thighs.

Especially her thighs.

Idly, Haru felt a trail of drool run down his chin. Even more idly, he wiped it away.

"You…" Mom's voice trailed off. There was something odd about it. Different. Something like confusion but also something Haru hadn't ever gotten from his mother before.

Only then did the boy realize what was off: his mom didn't have red eyes.

"You're my master." It wasn't a question. Actually, she almost sounded surprised. "You."

Nevermind, she definitely sounded surprised.

"And you're not my mom." How he managed to keep his voice level he didn't know, "Where is she?"

Without thinking, he let his mana flare. A wave of power spread from him in a light-blue corona. It was a bad habit of his that he'd picked up when he'd been even younger and only grasping at the concepts of his power as a magus.

It wasn't really meant to do anything except make himself feel more confident. Mom suspected it was something he got from the TV. From the animals that liked to make themselves look bigger.

But this time it did more than just make a corona of pure mana around him.

The woman that looked like his mother stumbled to her knees, her body overcome by shaking he'd never seen his mom do before.

Haru couldn't take his eyes off of it. Of her. The way her body moved as she fell, the way her curves jiggled.

And her voice. The woman loosed a groan, breathy and throaty and deep. It reached at something in him, something Haru hadn't known he'd had. His belly tightened, and he gasped.

In the back of his mind, chains jangled.

~TtT~

Ishtar's world shook.

She'd had her doubts when she'd first felt the connection fall into place. Was this really her master?

He was a boy. Maybe no older than ten or eleven summers. That he could summon her at all was a miracle. That he'd be able to maintain her in physical form was an even greater miracle still.

Then he'd let his mana flare and whatever doubts Ishtar had melted away.

A tidal wave of power crashed into her through their connection. Overloading her newly-created circuits with a river of fire that set her new body alight. It burned, it electrified. And Ishtar felt it go to two very specific places.

First was her brain, which swam with energies and sent her tumbling down as she lost what little control she'd had over her fresh limbs.

The second was lower, to the space below her navel. Her womb.

It was flooded with liquid fire and a tightening pressure both. The space between her legs almost immediately overflowed with honey as Ishtar lost control of herself, overwhelmed by sensation. Sensation she realized was unmistakable arousal.

Her thighs shuddered, and she'd had to hold herself up with her hands lest she fully collapse unto the cold stone floors of the basement she'd been summoned in. Cunstyrups flowed hot and thick down her thighs, threatening to pool around her.

This… This was different.

Ishtar had been summoned before. More than once, in fact. But this was the first time she'd felt things so… viscerally. It was almost like… like-

Scarlet eyes widened as the realization came to her: This boy hadn't just managed to summon a goddess, he'd bound her in the body of a living woman.

Oh. Oh dear.

The goddess gulped.

Ishtar would manage. She was a goddess still, and wielded practically all of the power besides. She was also a more than capable fighter should push come to shove, and she was hardly inexperienced.

Still. She was mortal right now. Bound to a mortal body. Bound by mortal needs, bound by many mortal limitations.

Bound my mortal weaknesses.

Whatever else she was worried about, whatever else she might have thought on the matter of her master, or on the matter of her vessel, immediately fell away as she felt the boy's mana leave her. The connection coming down from the intensity of a sun flare reduced to a trickle she'd only noticed because of the absence thereof.

It was cold. So… so very cold. Empty.

Red eyes widened, her mouth hung open as she made the realization:

Her master's touch. The feel of his mana. His power.

Ishtar needed it.

Ishtar needed it.

Without thought, she reached out. Fingers and toes numb, her body weakening by the second.

Her master flinched as she fell atop him. The boy fell on his ass without much of a fight, which might have been a blessing for her. After all, this had to have been a fluke. He hadn't even known who she was, hadn't even realized what he'd managed to pull off. This… this child might have been a prodigy as far as potential and future capability was concerned, but he seemed to no not be much else.

Right?

Ishtar felt an electric tingle run up her spine just from the feel of his warmth. The smell of his power radiating off his skin as a scent she was sure only she could sense. Her fingers crept up beneath the loose shirt he wore, clammy hands rubbing against the young and smooth skin of his belly.

The goddess took in a deep whiff and groaned.

"Wha-" His confused whisper was abruptly cut off as Ishtar dove in for a kiss. Her tongue invaded the boy's already open mouth and tasted him. Her master didn't have a lot of fight, more inhaling her tongue than wrestling it. His tongue thrashed against hers like a confused snake while the steamy jets of air coming from his hyperventilating nostrils brushed against her cheek.

Lightning.

She felt her whole body sputter as she tried to dive deeper, trying to press herself into him hard enough that she must have made an excellent impression of a starfish wrapped about a rock.

And it was quite the rock. For despite her master's weak attempts at pushing her away, despite the surprised cry that was sending vibrations down her hungry, hungry, hungry throat, Ishtar could feel a hardness building between her diminutive master's short legs. The boy's young cock started to tent his loose shorts and teased at the bound goddess through the arm that was teasing at his thigh and belly.

The warmth pooling at the base of her belly turned downright molten when she felt just how… endowed her master was.

Hot. His skin was hot, and the electric warmth radiating off him only grew hotter still as Ishtar finally let up from his lips and dove down for his neck - to the place where his jugular should be.

What followed was a sound that was cross between a groan and a squeal. Confused, afraid, and excited. All sentiments that Ishtar could share, except she was also hungry.

Mana. She needed her master's mana.

Her hand went down from the boy's tightening belly to the hardening bulge above his shorts. Briefly, scarlet eyes looked down and widened when she saw how far it overshot past the straining waistband, how it curved.

"That…" Lost to the hunger, Ishtar took another deep whiff of her master and failed to suppress a giddy giggle, "That looks like it hurts, master."

Ishtar's master whimpered, instinctively thrust into the palm of her hand in search of relief. The rest of him squirmed in her grasp.

"So hard…" The goddess hummed as she moved up and down, felt the way he throbbed in her palm and the way his heat leached into her. "So big…"

Hands trembling, she pulled back the strained garter.

It towered over her. Veiny and throbbing and angry, snapping to attention as it was finally freed from its confines. Her master sighed in relief while a wave of fiery air washed over her.

Too hot. She was feeling too hot. Ishtar couldn't breathe.

Before she could second-guess herself, she reached for the veils that covered her chest. Thin things, but enough to make her feel like she was suffocating. But even after she'd pulled the offending cloth down, it still felt like she was breathing in only fire and she felt her body grow hotter.

A heat that only continued to intensify as she unsteadily took hold of her master's fuckpillar.

"Like that, did you, master?" She couldn't help but grin down at him when she heard him gasp, only to be treated to the sight of golden eyes looking wide at her heaving tits. The irises darted to and fro, focusing on what looked to be the sheen of sweat that formed in her cleavage and her pert and pink nipples. "Like the view?"

Whatever answer the boy might have been able to come up with in the sexually-charged haze that had overcome the two of them had been lost the moment her hands began to stroke up and down. She had to hold on tightly, eyes rolling into the back of his skull in just the most delightful way. The goddess could feel the blood pounding in his veins, pulsing just beneath the skin of his neck against her cheek.

She couldn't help but give him a little nuzzle, humming as she pressed her lips to the space where his shoulder met his neck.

His shaft was drying than she'd have liked, even with the claminess of her hand helping a little bit.

Which was why, with only seconds to lament the need to pull her face back from her master's skin and the mana coursing just below it, the servant drew her hand back and spat a nice, thick wad of spit on it. And, when she decided that wasn't quite enough, she let her tongue hang out and a stream of the stuff to deep down.

It was only when she could feel some of it overflowing from the small cup she'd made did she return her hand to her master's cock.

The boy's back arched upward as she resumed her handjob, a slow and languid pace that slowly ramped up as the goddess felt her own excitement build from the way her master responded to her ministrations. Small gasps, cute wails, hand thrashing as though looking for something to ground himself, too.

He was confused, the poor thing. She was probably his first sexual experience. This virgin boy that had somehow been powerful enough to drag a goddess out from the abyss to inhabit this woman's body, and suddenly being driven to the heights of pleasure without so much as a 'by-your-leave.'

A swell of pride overcame her as that thought came. She was this boy's first. She, a goddess. Licking her lips, catching the taste of his skin, Ishtar came to a decision.

"Loving this, master?" He shuddered as she sent a breathy whisper through his ear, her tongue sticking out to lap at his lobe as she cupped her spit-slick palm over the head of his cock. "Does it feel good to have Ishtar serving you?"

She hadn't even remembered to keep her true name from him.

But the way his cock swelled in her hand gave her all the answer she needed.

Finally his hand found an anchor. One that made Ishtar arch her back into him: her tits. Small hands grabbed at the heaving titflesh, pawed at the softness of her. And he'd been charged with mana, mana he didn't seem to know how to control.

Or perhaps he could control it too well.

Ishtar gushed as she came first. A wave of electric pleasure going from her pinched nipples and caressed titflesh all the way to her brain and the revved engine that was her core. Legs twitched and whatever pace she'd built with her handjob breaking down to frantic stroking as she tried to stifle her scream.

She failed. She failed, and the only way she could think to smother her shame was to press her lips to her master's.

Her scream met his moan, both their bodies shaking. Her's in the orgasm she was riding through and his tightening in the climax Ishtar was sure was fast approaching.

The goddess felt her tongue tingle. Mana. Not a lot of it, but it was there, and it reminded her of what it was she was doing this for. Mana. Mana from her master's fluids. Mana from his cum.

Strings connected their lips together as the servant pulled away. Strings that snapped as she moved her mouth from his lips to the angry head of his cock. And she'd been just in time, as the boy loosed a guttural groan - an animal's groan.

He came. And Ishtar saw white.

~TtT~

Matou Sakura wasn't entirely sure how this all happened.

She'd gotten the gist of it from her nephew, of course. Her sister had summoned something, likely a servant, but it had latched on to little Haru instead. In the babbling mess the boy had become, he'd also mentioned other things, but she'd been unable to understand what else he'd said.

But what she didn't miss was how her sister hadn't been the one to call her. Which meant Rin was in trouble. And while Sakura wasn't the magus that her sister was, she might have been the closest one physically. And the only one that Rin might have trusted.

As she'd made the trek to the Tohsaka house, Sakura considered contacting her brother. He'd been the one to actually do the summoning for Rider during the last Holy Grail War, after all. And while he might not have any magic circuits, he knew theory better than she did.

It'd be a pain, however. Her brother was all the way in England, and Sakura didn't even have his number. She'd be forced to use the mail and there was no telling when he'd be able to get back to her. No telling how bad things could get with her sister.

So it was with no small amount of uncertainty that she arrived at the door to be greeted by her wide-eyed nephew and immediately taken to the locked door of the workshop where her sister had been trapped.

What followed was a full explanation after she'd calmed the boy down, and her violet eyes widened as he told her more of what had happened before she'd arrived.

Not only had her sister managed to summon a servant outside of a Grail War, but from the sound of it, Rin had summoned her servant into herself. That… that was something Sakura didn't know was even possible.

And after all of that… seeing her nephew's flushed face, his disheveled appearance, and the command seal that he'd already somehow used, she could only sympathize. The personality her elder sister had summoned had accosted the boy, and only his instinctive use of the command seal had kept the servant trapped within Rin's workshop.

Considering everything that had happened, Sakura would have considered herself impressed. Something she'd made sure to tell Haru as they both walked down the stairs to the basement. It was rare to become a Master even if he'd not really done the summoning himself, to be able to keep control over his servant on instinct alone?

There might be a prodigy before her yet.

But when they arrived at the workshop, the sight before Sakura left her only able to say one thing:

"Oh… Oh my."

Her sister - or the servant inhabiting her sister's body - was bound by her nephew's magic. Though that wasn't what really caught her eye, however.

No. What really caught Sakura's attention was the assault on her senses.

First was the smell. Her sister's workshop had never been particularly well-ventilated, so everything that had happened had definitely… stuck, proverbially, speaking. It had certainly stuck to the servant's skin, caking her sister's body so thickly that it reflected the red glow of the runes binding her.

There was just so much of it. Between her sister's tits, glazing her face so much that one of the glowing scarlet eyes had been glued shut. It had gotten in her hair, too, leaving her sister's brown mane in sticky and matted clumps.

Sakura froze as she just took this in. Little Haru… Little Haru had done this?

From the corner of her eye, she sent the boy a look that he didn't notice. He was too focused on hiding his embarrassed face in his hands.

Surely not. Surely this son of Rin's hadn't been able to put out that much. Sakura was not a virgin by any means, but she knew that this amount of semen couldn't be pumped out by a single man, much less a boy her nephew's age.

Right?

~TtT~

A challenge. They'd both been challenged.

Sakura didn't know how she was supposed to take the servant inhabiting her sister seriously, especially when the servant had still been completely plastered with her nephew's semen.

But servant Archer didn't seem bothered by it at all. Even with one eye shut, Sakura had been challenged.

"You want me to leave? Defeat me."

Arrogant thing. The older woman looked at Sakura smugly while idly scooping up globs of cum and dragging it into her mouth. It made Sakura shiver from disgust, a sneer coming unto her lips when she saw just how excited it seemed to make the servant: Archer's pale skin flushed, the once-haughty gleam in that scarlet eye disappearing as she seemed to lose herself in the sensation of her nephew's cum.

This had managed to take over her sister?

"You're not a servant," the servant answered her unsaid question, smiling almost drunkenly, "you're not my master, either, and I'm only really obliged to obey him."

"And Haru-kun's opinion on the matter didn't matter to you?"

It was so strange, seeing her sister's eyebrow arching while it was still off-white from the slightest glaze of cum. By the Root, Sakura could still smell her nephew on the thing, and it was damn distracting.

"Master didn't seem to mind. Oh I'd say he didn't mind at all."

Archer's voice changed halfway through her statement. It turned deeper, breathier. A sound Sakura hadn't known her sister was capable of making. The younger of the Tohsaka sisters gulped, her throat uncharacteristically dry at the thought.

But even from where she stood facing the servant, Sakura could feel it. The telltale tingle on her skin, the light scent of ozone and the heat that seemed to reach through her clothes and straight through her. Mana. Power.

It was Haru's, and it was all over the room. It was strongest from the servant, but Sakura didn't miss the still glowing summoning circle. Dull as it was, there was still power there.

This servant wanted to be defeated before it freed her sister and nephew from its influence. Sakura would need a servant to do it.

And Matou Sakura was still a magus.

~TtT~

"What are you doing!?"

His mother - Ishtar - hissed. Though he'd come to realize it wasn't her, he could still hear the outrage that he sometimes heard from his mother when she was scolding someone. And while it wasn't always him that was talked to this way, Haru had seen the look on her face enough times to know exactly what expression she must have had.

But he couldn't. In fact, the young master could barely see anything at all. His eyes were open, but looked only in one place. And with the darkness that clawed at the edges of his vision, he could only see one thing.

The same thing that had taken away his ability to pay attention to much of anything at all, really, and where all of the blood in his body was currently headed.

Scarlet eyes practically glowed in the fading light of the summoning circle. His aunt's eyes. Purple had turned red, and his aunt had changed in a flash that told him that she'd gone and done the exact same thing his mother had: summoned one of these so-called 'servants.'

And, like before, he could feel the same sort of connection snapping into place beside him, feel some of his mana be siphoned off to support this… this thing that his aunt had become.

And, like before, he'd flared his mana in panic when he saw the now-familiar look in his new servant's eyes.

That had been a mistake.

Because now, he was back on his ass, with the new servant's arms holding him down and her mouth on his cock. Which was where all of Haru's attention had gone.

Soft, velvety. Tight. But where Ishtar had been desperate and hungry, this new servant almost felt practiced.

Even then, she'd not gone for him first. Instead, she'd pounced on Ishtar, pinning the other servant down with ribbons that Haru was sure hadn't been there before. Bound as she was - and surprised, Ishtar hadn't been able to fight the other woman off as she pressed her face to the other woman's neck and… licked.

And licked and licked. His aunt-servant going at Ishtar to get every last drop of his cum that still glazed her skin.

She hummed, she moaned. Haru had been sure he'd seen her body shake the more of the stuff she'd gotten into her mouth.

But he hadn't been able to take his eyes off her. Mesmerized at the way both their curves pressed against each other, the sounds Ishtar made as she struggled against the bindings that the other servant had bound her in. How his mother's back arched and pressed into his aunt while both of them shivered.

So distracted was he that he hadn't been able to react when the servant controlling his aunt had turned her scarlet gaze to him.

He hadn't known what hit him.

Which was why he was in the predicament he was in, with his aunt's body pinning him down while her hands held his own in some weird and perverted twist of affection. A hold he returned so strongly he was sure his knuckles had turned white.

Because they were his anchor right now. In a world that had fallen away and his body squirming as he felt as though all of him was trapped, his hold of her was the only thing keeping him from closing his eyes and losing himself completely.

He throbbed inside her throat. She swallowed, she hummed in what might have been approval. It sent earthquakes down the full length of him, all the way to the base of his cock. So much so that he could feel his own hips quiver, sometimes thrusting up into his aunt's mouth while he gasped in great gulps of the musky air. Air filled with his mana.

"Get away from him! Don't you dare touch my master!" Ishtar was almost feral now, though Haru could still tell she was bound. The barest silhouette of her trying to break free of the bindings.

"Do you like it, master?" Golden eyes opened wide even as he could still barely parse what he was seeing. Still, her scarlet eyes came through. Glowing with power despite how some of the tears leaked down her cheeks and reflected the light.

"H-How…"

Lips pressed tightly to the base of his cock. She was squeezing, she was swallowing. Now and then, Haru would feel her tongue peak out from the vacuum seal she'd made. She'd slather his balls and draw circles around his length.

"A little trick I know from being a servant." Her voice once more echoed inside his mind. It was Sakura but it wasn't, much like it had been for his mother. But here there was a breathiness to it, somehow. A breathiness that almost tickled the hairs on the back of his neck. It certainly made him shiver again - above and below as she almost breathed in his cock. "Isn't this great? I can talk to you even while I drown in your cock."

Haru could only groan as he felt the way her throat pulsed rhythmically, trying its level best to drag him down and down and down. The world narrowed further until only the glowing of her eyes were left to him.

"Sa-... Ohhh… Sakura-baasan."

"It's Kama," the servant answered, her voice sounded like she was smiling, "I am servant Assassin. But call me Kama."

"Kama…" he could feel his balls tightening as she continued her sweet torment, "Close… so close…"

So close that when Kama suddenly pulled herself off his cock Haru wailed in pain. Dissatisfaction and the real world came crashing back down unto him that it was like being thrown out of a dream. His vision returned, and he looked up to see his aunt's body staring down at him with no small amount of smugness.

Throatslop, drool, and precum drew a bridge of shiny sex between her mouth and every inch of his cock.

He'd been at the edge. Teetering. His balls tight and ready with his cock practically shaking in readiness. But as the comparatively cooler air surrounded him and the silkiness of Kama's mouth turned into a memory he found himself backing away from the precipice instead of diving off it like he'd done with Ishtar.

Kama wasn't done, however. Her well-trained hands attacked him again: one cradling his aching balls while her other snapped their connection and used the still-warm lube to tease at the head of his cock.

As hypersensitive as Haru was, it wasn't long before he was tremblingly dragged to the edge of the pit of his own orgasm again.

"Kamaaaaaaaaa~," he wailed when he felt her back off him again, this time moving to she was straddling his legs and his cock was pressed against her belly.

"Not yet, master," she trapped him against her, the full length of his cock reached well-past her navel and the warm smoothness of her skin kept him excited. Her hand reached down and pressed the bottom of his cock to her, "I want to savour it when you cum."

The torment continued. Once, two times, three times more. She didn't move him anymore, and kept him against her womb while she edged him. Kama joined in on her hands, too, actively rubbing her trembling womb in a full-body motion that sent her bobbing and bouncing hypnotically.

It would have been beautiful if it didn't cause him so much suffering.

Haru gritted his teeth. Hands flailing and trying to grab at his aunt's body only for her to use one hand to swat him away while the other kept stroking him. Torturing him. Dragging him up and up and up to the very top of the mount of pleasure, but refusing to let him find release.

And eventually Haru couldn't take it anymore.

There was a flash of light, a flare of mana as two screams filled the confined space of the basement workshop.

He pounced.

~TtT~

She'd made a mistake.

Kama had expected a boy. He was a boy. He certainly looked like one. Sure he might have had more mana than usual, but a child was still a child. And she was a goddess. A love goddess. There should have been very little a child like this could have been able to do to resist her.

And that looked to have been the case. She'd left him a gasping, mindless mess beneath her hands as she edged him again and again.

Kama wanted him there, wanted him at her mercy. Kama was supposed to be in control, supposed to be the one calling the shots.

Supposed to be.

Wave after wave of her master's influence crashed down on her now. Matched perfectly with each and every one of his thrusts as she felt more and more of him enter her. Kama knew how potent her new master's mana was. It had been the first thing she'd noticed after she'd been summoned, after their bond had snapped into place.

Power. Thick and heady and tantalizing. In the air, electrifying her skin, and calling to her even as it sat glazed over the skin of the other servant - Archer. She'd been unable to help herself, pouncing on the other servant and lapping up her fill before she'd realized what she'd been doing.

Nice. That was the best way for her to describe it, and her servant-body craved more. Demanded more.

Honestly, she should have realized that as a warning.

When she finally managed to get herself back under control, she realized the danger she was in.

The boy-master oozed potential. Kama had felt herself grow lightheaded from just the smell of him, and it had only gotten worse when she'd taken her few licks. Lightning on her tongue, down her throat, and piercing directly into not only her host's magical core, but into her very soul.

Also, her womb.

Her womb which throbbed.

Her womb which trembled whenever she felt her master's cock slam against its entrance.

Something he simply refused to do anything but. Frantic though he may have been, her new master was nothing if not enthusiastic. Each stroke pulled himself out of her almost entirely. It threatened to drag her insides out, it felt like. Her fleshy tunnel clung to him like a second skin, only for him to hammer everything back inside when he drove forward.

A thundercrash sent directly into her deepest parts, a powerful wave that reverberated outward until even her fingers and toes were tingling from the intensity of it.

But before it could even die down, he'd pull back and strike at her again.

Slam. Slam. Slam.

The sound of flesh slapping against flesh filled the room and filled her ears as she felt her senses begin to fail her. Or perhaps, it would have been more accurate for Kama to say that her senses were overwhelmed.

Her world narrowed, vision darkening everything except the sight of his small body staring down at her with something crossed between anger and hunger. All she could hear were her ragged breaths, her failed attempts at forming words that ended up spilling from her sputtering lips as gasps and moans. All she could smell was his musk filling the room with the same thickness as his power did, a promise of just how thickly he could stuff her with his power.

Kama shuddered at the thought.

And the feel of him. Grail. He was thicker than anything she could remember, past life or no. Her host-body's insides rearranged themselves with every thrust, the impact of his member jostling the very organs of her torso before it plunged her brain into a warm bath.

Fuck drink, she could only lay limply beneath him as he took his pleasure from her. Golden eyes practically glowing with power while he pistoned down into her with a strength a boy his age and size shouldn't have possessed.

Couldn't have possessed.

Reinforcement, Kama realized. With all the mana in the air it might have been impossible for her to catch it. Only through feeling it, through feeling a child overpower her - as little control over herself she might have right now - could she guess what could have possibly caused it.

Slam. Slam. Slam.

A lucidity that almost immediately left her as an electric storm was rapid-fired into her, each one stronger than the last.

Slam.

Kama felt it.

Slam.

There. In the entrance to her womb.

Slam.

It surrendered.

And the servant screamed as she felt her whole being do the same.

~TtT~

Ishtar couldn't move.

The bindings the other servant had wrapped her in had fallen away the moment her master had taken charge. Something Ishtar had only been too happy to relish in as she took in the way the other woman screamed as the boy mounted her and wielded his cock to show the upstart servant her place.

But now, unimpeded as she was, Ishtar couldn't help but watch. Oh she'd made sure to clean herself up, dragging her hands and fingers all over herself to scrape at whatever remained of her master's precious cum and shove it directly into her mouth.

Another reason for Ishtar to resent her. How dare she take what was hers. And to make matters worse, she was the one being fucked by the master, too!

Her hands drifted down to the base of her belly, to the womb that her body and soul both wanted the boy to enter. She gently massaged it as she watched the boy plunder her host-body's sister for whatever little it was worth. As it almost seemed to cheer.

Because it was cheering. Ishtar knew, somehow, though she couldn't name the reason for it. The body she was inhabiting was relishing this. Her host wanted to be a part of it. Hungered for it.

Ishtar wanted to be the one being pile-driven into the basement floor. Her host wanted it, too.

She didn't move, though. Not because she didn't want to, but because the master hadn't asked for her.

Drowned in his influence as Ishtar and her host-body had become, they knew better than to disobey - by neglect or otherwise. If the master didn't want their holes to comfort this cock, then they would sit there and wait. And watch.

Ishtar couldn't even find it in herself to take pleasure in the view. It wasn't her place to make that choice. So instead she teased at her belly, shivered as she felt the pressure being placed on her womb - the same womb that had carried and birthed the boy that was now her master.

The same womb that now desired to have him return, as conqueror instead of son.

Her whimpering joined the chorus, the sounds made of her master's pelvis slapping against Kama's soft curves while the white-haired servant's half-wailed groans filled the room and bounced off the stone walls and inside her submissive little head.

And then he pierced the Assassin's womb. A piercing scream erupted right before it died and a fine mist of girlcum sprayed itself against her master's crotch and stomach.

But it was the sight before her that Ishtar couldn't take her eyes off.

With his prodigious size, Haru reshaped the other servant's body. An unnatural tent was made below Kama's navel, pointing sharply upward and looking like it might burst all the way through. It twitched, it shivered. But still Ishtar could see how Kama's body tried to squeeze against it, how every muscle of hers cramped as she came around the master's cock. Came from his invasion of her womb.

Not that it seemed to stop the master any, though instead of full thrusts he devolved into a fast-paced rutting.

Scarlet eyes looked at the horrific and unsettling view with wide and fascinated eyes. Each time the master bottomed out, the bulge would twist with his movement. Spearing skyward and sending all of Kama's body following. All of her limbs now hung limp and useless at her side, her shoulders on the arousal-slick floor while her ass was completely lifted off it with the force of Harus' fucking.

The next time Kama came, Ishtar did alongside her. Her hands pressing so hard against her womb that it had been enough to drive her over the edge and send a rush of girlcum between her thighs to join the already growing pool on the floor.

And it was with that shame - from failing to be patient and wait for her master - that she watched as he finally, finally came, too.

When Ishtar had been bathed in Haru's semen, a part of her had wondered what it would be like for him to cum inside her womb. As he did so in the Assassin, she found exactly how.

Minutes. He'd cum for minutes. Shot after shot of cum he fired all while continuing to rut against the poor, mindless woman. His eyes gleamed with sun-stars and his teeth grit, hissed breaths coming in through the gaps.

The other woman's stomach ballooned. Each shot of her master's semen flooded the enclosed space and made her look almost pregnant, herself.

Only when he finished, only when he loosed a relieved breath and seemed to relax atop the Assassin's defeated body, did he finally turn his gaze to her.

"You," he said, voice commanding and charged with enough mana that Ishtar's very core felt him call to her, "come here."

~TtT~

Chains of mana and control tightened around both the servants. Their shared master's connection to their soul-selves attacking their free will with his own desires, whether they were conscious or not.

And in the material world?

The whole room was filled with this mana. His very energy danced on her overstimulated and tender skin. Kama could still taste him on her lips, in the back of her throat. His hot sludge still clogged the back of her throat while his girth threatened to suffocate her. She could hardly breathe.

And inside her.

Grail.

She'd been filled with a supernova. A core of molten heat so intense she could feel it radiating outward in every direction. Another vector for her boy-master's control over her - over the two of them - to secure both goddess-servants into his service. Permanently.

Because Kama could feel it. Feel as more chains were added to the one around her metaphorical neck. She could see how they intertwined with the other demi-servant, and how more and more was being added each time the boy - master Haru - used them.

It was why she could feel the load he was pumping down Ishtar's throat, feel her struggle to breathe as a boy that wasn't even a teenager wrapped her long, brown hair around his hands and used them as makeshift handles to manhandle her as he so pleased.

Kama could feel how good this made the other servant feel, feel the pounding of the blood in her skull and the thundering of her heart. How her neglected and empty core tightened even as Kama could feel just how thoroughly master Haru had filled her.

When Ishtar came, so did Kama. Both women sending a misting of shameful defeat and submission to join the already musky and mana-rich air of the ritual basement.

And as they did, tighter did the control of their master grow over them.

Not that the boy seemed particularly in control now. Not in the usual sense, at least. Because while he did dominate them, he'd lost himself completely to his own urges. Urges that were flowing into both servants through the strengthening link.

Which was why, when Kama's body finally found the strength to move, she crawled her way through the pool of cunt-syrup and semen to settle herself between the master's legs. Her tongue slathering at the boy's nutsack as he ravaged Ishtar's throat. The Hindu goddess lapped up at her counterpart's throatslop, planted kisses at the base of her master's shaft whenever he pulled back and even stroked the incredibly prominent bulge that appeared whenever he drove Ishtar's face to the base of his member. Her hand joined in to fondle his balls as he worked himself towards an inevitable orgasm.

All the while, she egged him on. Her hoarse voice mingled with the other servant's strangled gagging.

"Look at her inhale you, master Haru."

"Does my hand feel good when I jerk you through her throat? Look at how much of you there is?"

"Cum in her, master. Cum in her until all she can taste is your semen and her every breath smells of it."

And, when the boy finally finished himself in the stomach of his mother's body, Kama was there to slurp up any of the overflow that came from Ishtar's mouth or nose.

When he finished with Ishtar's mouth, he fucked Kama again.

And then again.

When her womb was so full with semen that looked like the poor goddess might burst, he'd deigned to spray his immense load straight into the white-haired woman's hair instead before stuffing his length down Kama's throat before eventually ordering Ishtar to jerk him off with the other servant's semen-soaked hair.

Kama, delirious as she'd become, suckled her master's balls until he came again.

All the while, the link grew stronger.

~TtT~

The rest of the night devolved into a strange and otherworldly blur for both servants.

Master fucked their mouthes, drove his cock into one of their asses, stuffed one of their pusses with so much cum that they were sure they were pregnent now. Each upsurge of mana-infused semen widened the way a river carved away at a gorge.

Again and again until the line between where Kama ended and where Ishtar began blurred.

"Good," one of them whispered - they couldn't tell who - "So good, master,"

Their womb was crushed as they rode him. Master's cock lodged in their guts so thoroughly they could see it through their front belly, whatever semen that had been deposited in their baby bag completely pushed out.

Not that it stopped them from serving him more, hands working through the pain and electrifying pleasure to stroke his cock as best they could from the outside.

The other was sitting on his face, pussy being lapped at by a boy that didn't have any idea what he was doing. But with how both servants were so sensitive from being drowned in his mana that just his touching their skin sent them into a frenzy, it didn't matter much.

Neither goddess could think anymore. Their minds were a haze of enraptured suffering, overshadowed by the undeniable control of the boy-master that had strangled them with his control. It had gotten so absolute that his very whims could force their bodies to move, even when it would have been beyond them, otherwise.

Like now. As they rode his cock and came and came. Their numb and shuddering hands stroked at the cock through the cocksleeve of a woman that surrounded it while touching every inch of the boy they could get their hands on.

In submission, in worship.

Not even their mouths were idle, though their foggy minds could barely string a thought of their own, they could manage to say whatever it was they needed to egg their boy-master on.

He'd turned them into cocksleeves, into toys.

~TtT~

"Do you like this, master?"

Haru's cock was surrounded by ass-fleshs, two pairs of cheeks pressed around the sides of it while the cum-glazed servants moved up and down to jerk him with their cheeks.

The boy had fucked every one of their holes by this point. Stuffed the other pussy after he'd had his fill eating it out, let them take turns warming his balls while he injected the other with his sludge-like load.

Mouths, pussies, asses. He'd even had them give him a titfuck while he suckled on the other set of tits, his disappointment at the lack of milk only remedied by the feeling of his mother's tummy fluttering in a tit-induced orgasm from how he bit and sucked and pulled at her while he made a river in Kama's cleavage.

He yearned for the taste of his mom's milk, flowing into his mouth as he fucked into her from above or as she pleasured him with her hands.

It had been a long night, and all he could really smell now each time he took a breath was the thick and heady scent of sex that now choked the whole workshop.

But Haru felt more alive than he ever had. His powers were getting more practice tonight than any other training session his mom had given him before, and he was enjoying himself.

"Ooooh…" he groaned, his balls tightening as both servants picked up their pace.

This… ass-job was new. And it felt very different from everything else he'd played with so far. The firmness of their tailbones pressed against the sides of his cock while their soft and pillowy cheeks smothered the top and bottom of his cock, practically drowning his head each time they got to the top. Spit, pussy juices, and his own cum overflowing from their overfull asses served as lube. White, foamy, and slick.

He'd drag them to his room after he came, after their backs were coated in a layer of his cum. Use them until he was satisfied, until his balls were - finally - well and truly empty.

When he'd let go of his control, when he'd dirtied his mother's bedroom floor with the same layer of sex that had veritably ruined her workshop, he'd been greeted with the broken and well-used forms of his returned mother and aunt.

Their holes gushed cum, bellies stuffed, and bodies shaking with an orgasm that didn't seem to end. Their pussies an endless river of girlcum while their bodies twitched and their stomachs cramped around all the loads he'd deposited there.

And Haru? Haru went back to his room to sleep. The best sleep he'd ever had.

Chapter 2: Epilogue

Summary:

The little Servant-summoning incident in the Tohsaka household has come and gone. And, as things start to settle down back into normality, we learn that 'normal' isn't what it used to be anymore.

Notes:

So I'm supposed to be on break this week, but I found time to get this epilogue done! It's not very long, of course, but it's mostly a victory dance - not even a lap, now that we're at the end.

Cheers, and enjoy!

Tohsaka Rin wasn't the type to let her son sleep in.

Little Haru was still a Tohsaka, after all, and it wouldn't do for someone of their pedigree to be lazy. It hadn't been for her, and she'd vowed to herself that she'd damn well make sure her boy wouldn't be the same.

But he'd been working so hard the last few days. Ever since the servant summoning incident from a week ago, he'd been applying himself much harder than before - and that was considering her darling son had already been quite determined.

It was why she was very happily prepping breakfast for her boy to enjoy in bed. She had no intention of making this a regular thing, of course, but she ought to show her little Haru her appreciation every now and then.

Granted, that had been the point of summoning a servant for her son in the first place, but that was neither here nor there. Some food was, at least, a lot more reasonable and less likely to cause any damage than a Heroic Spirit might.

The servants were gone now, sent back into the void after Haru was done with them.

Though it wasn't without leaving some permanent marks from their inhabiting of her and her sister's bodies.

Marks that were as visible as they were hidden from the naked eye. Rin could feel the way her larger bust now pressed against the back of the tray as she made her way up to her son's room. Rin hadn't been so… endowed before. She hadn't been as modest as she'd been when she'd been in high school - not since she'd had Haru, but she certainly wasn't this large.

All of her bras were very uncomfortable to wear now. Too tight. It had gotten to the point that Rin just forwent wearing one at home.

It wasn't just her breasts that had changed, however. Her legs, too, had gotten plumper. But that wasn't as much of an issue for her since she already favored skirts anyway. But having her thighs rub together the way they did still took some getting used to.

"Haru-kun…"

Rin found her son awake as she opened the door. But he wasn't alone.

Her younger sister was naked, legs spread wide as she sat on her Haru's lap.

Sakura, too, had changed from her experience having Kama inhabiting her body. Besides the enhancement of her curves - of her tits that now hung low and heavy and leaked milk like she was a prized cow - her hair had turned snow-white. It had grown longer, too, when Kama had borrowed her body, but she'd kept it that way even after the servants had left.

It now pooled around her, running down her back as in a waterfall of white and shining with the rising sun coming through the window.

But her sister didn't move. At most shivering as she… sat there while her son's cock deformed her belly with its girth.

"Good morning, Haru-kun,"

The breakfast tray was on the nightstand moments later, with Rin crawling unto the bed afterwards. Her hands brushed around her sister's hips, Rin loosing an excited breath as she felt the way her sister trembled beneath her touch.

Everything was warm. The feel of the back of Sakura's thighs as they pressed against the front of her own. Her sweat-slick and clammy skin carrying the heat emanating from deep in her core - from deep inside where her son was. The air, too. Steamy and cloying like she was back in her workshop on that fateful first night.

Because she remembered it. She did.

Tohsaka Rin might not have been in control while Servant Ishtar had practically destroyed herself on her son's cock, but she'd been able to feel everything that had happened. The lightning that had struck her core and spread outwards as she came around Haru's impossibly large cock, the way her body simply surrendered as she fell down the nigh-bottomless pit of climax, the immense satisfaction she'd felt whenever he'd finish inside her… on her… from her.

Every little bit of it had brought her pleasure, pleasure her body remembered still.

Pleasure her sister remembered still. It was why the two of them had begun to build their lives around staying with little Haru. And his fuckpillar.

Rin felt him twitch as her hands slipped over Sakura's hips and towards the very prominent bulge Haru made with his cock. She could feel it even through the overstretched womb that could barely hold him in: his firmness, his heat.

Virility.

"Ahhh…"

Sakura squirmed as she was attacked from both directions while Rin leaned forward and rested her shoulder on her sister's chin so she could get a better look at her son.

Where the Haru from that first night with the servants had been confused and overwhelmed, her young son was now in control. Golden eyes gleamed with a now-familiar hunger, meeting her aqua eyes with a confidence he didn't have before.

Rin's moan joined her sister's whimpers as she wrapped her hands around her son's length through her sister's womb and began to stroke him. Slow and sensual, as he seemed to have grown to like on most mornings before he had his food.

He'd finish once in either of their pussies then have his meal while the two of them shared theirs from his cock, coaxing his second load with two sets of mouths that choked on his length and begged his balls for it.

Only afterwards would he take them more actively. Sometimes it'd be in their asses, sometimes it'd be in their pussies, or sometimes it would even be on their hair. The last had become a very fast favorite of Haru's to do since his aunt's hair had turned white.

All before Rin wrapped her own locks around her son's sex-slick rod and coaxed one more shower of sperm from him before he got ready for school.

This was just the beginning, too, she knew. Rin's excitement forced her to bite down on Sakura's neck while her hand felt the way Haru's balls tightened and he began to release his first torrent off cum into his aunt.

Both of them screamed. Her sister into the muggy air of her son's bedroom, and Rin into her sister's quivering flesh.

Mana was injected into her younger sister, and Rin heard the jangling of chains in the back of her mind as his power was sent into her by the residual link that the servants had somehow left after their departure. Rin, Sakura, and Haru came as one.

More days would come, she knew. More days of her insides being rearranged by Haru's cock and his prodigious girth splitting her open in ways she'd never thought possible.

And as she looked down to see the boy smiling at her while he arched his back up in orgasm, Rin's eyes almost teared-up at the unfathomable joy she felt blooming in her thundering heart.

She couldn't wait.
