Ryouma Sajyou's POV
After the Holy Grail War came to its bloody conclusion, Manaka and I moved out of the house.
She was already pregnant with my child, and the two of us were busy enjoying the strange, twisted world we shared between us, while Saber and my father were left completely stupefied by how the war had ended before they even got a chance to make a single move.
They didn't know who had actually won or how it all wrapped up.
All they knew was that every single Master, along with their Servants, had been slaughtered.
Even my father's old friend, Aritoshi Reiroukan, had vanished without a trace, together with his daughter, Miyaka Reiroukan.
All the magi involved were utterly wiped out, except for the Sajyou family, which obviously freaked out the Mage's Association.
They wasted no time and sent someone from the Clock Tower to investigate the mess.
But when their investigators showed up, Manaka brainwashed them on the spot, turning them into loyal spies for us.
We sent them right back to the Clock Tower, letting them report a fabricated story that some mysterious magus had crashed the Holy Grail War and wiped out all the other magi by destroying their magic circuits.
As for why the Sajyou family was still perfectly safe and untouched?
The explanation given was that they'd never left their house, which was heavily protected by a powerful Magic Workshop, leaving no opportunity for anyone to assassinate them.
Of course, that lame-ass excuse didn't fool the Mage's Association for a second.
They ended up executing the poor bastards who brought back the report, figuring out instantly that they were compromised traitors.
Still, despite sniffing out the lies, the Association decided to drop the whole investigation altogether.
They just weren't willing to pour more time and resources into a remote country like ours.
In the end, they simply concluded that all the Masters died in fair competition.
Case closed.
With the Holy Grail War finally over, Manaka and I had already graduated from high school, and I was about to start my new life at university.
It's been two months now that I've been living between two worlds with Manaka.
Naturally, Assassin has been tagging along too.
Whenever Manaka and I were making love, Assassin would just sit there on the couch, pretending to watch TV, her face burning bright red in embarrassment at how rough and loud our sex always got.
Even after Manaka got pregnant with my child, I never once grew tired of her.
We kept having sex relentlessly for two whole months, me pumping load after load of my cum into her.
I wanted to make sure our future daughter was getting plenty of "nutrition" and maybe even a little company, so she wouldn't be bored in there inside the womb.
Manaka didn't bother going to college anymore and threw herself into being a full-time housewife instead.
And even though she could probably handle every household chore in an instant with magic, she actually loved doing it the regular way, taking care of me and the house with this bright, eager energy that turned me on every time.
Of course, when I say college, I'm not talking about some normal university in the muggle world, I'm talking about the Clock Tower.
But time skipped forward again, and that didn't really matter.
By now, Manaka was heavily impregnated by me, her belly round and swollen, her skin stretched tight.
Her whole body had grown more sensitive to touch during sex.
Her nipples were darker and slightly swollen, standing stiff even at the faintest brush of my fingers or tongue.
When I wanted the milk, I didn't have to wait or ask. I went straight to the source, her flat, milk-filled breast.
I latched onto her swollen nipple and sucked hard, greedily drinking down the warm liquid that leaked out in thick streams.
She smiled softly as I nursed from her like a beast, all while her hand lovingly stroked my hard cock.
Her fingers moved with slow, steady care, up and down, gliding smoothly over my shaft, her touch gentle but full of desire.
She helped me masturbate while I suckled from her, pleasuring me with one hand as her other cradled my head against her chest.
The milk was supposed to be for our future daughter, the one growing inside her swollen belly, but I didn't care.
I wanted it.
Needed it.
And she gave it to me without hesitation. I sucked her dry, draining her tit over and over while moaning into her flesh.
Her nipple twitched in my mouth as the warm milk kept flowing, coating my tongue and throat while my cock throbbed under her soft grip.
My pregnant sister, the mother of my child was feeding me like I was hers too.
We both loved it that way and didn't want to change a single thing, because it was hot as fuck.
When I was finally done sucking her milk-drenched tits dry, her nipples sore and leaking from my rough mouthwork, we shifted positions.
My cock was still rock-hard, veins bulging and soaked in spit and her lingering scent, nowhere near satisfied with just a handjob or titfuck.
It craved her flesh, heat, and that tight hole I'd already claimed so many times before.
I grabbed her by the hips and flipped her over, her body heavy with pregnancy, her belly slightly swollen and gorgeous as ever.
She moaned when I lined up behind her, pressing the thick head of my cock against her dripping pussy.
I didn't wait. I didn't hold back. I slammed into her with zero hesitation, burying myself to the hilt as her entire body jolted forward from the impact.
"Yes, brother! Give me your cock! Give me your fucking cock! I need it. No, I love it!" she cried out, as I started pounding her from behind, not giving a damn about how far along she was.
Her pregnant body rocked with every brutal thrust, her ass rippling as I slammed into her again and again, her pussy so wet and tight it felt like it was trying to milk me dry.
But I wasn't done.
Not even close. I was going to fuck her until she screamed.
Until she begged.
Until this baby inside her knew exactly how its father claimed her again and again without mercy.
My cock plunged all the way into her womb every time I fucked her from behind in the living room.
Assassin had probably already dipped out somewhere the moment our sex got this intense, leaving us alone to make a mess of the place.
Manaka was completely naked, her pale skin flushed pink under the bright lights, as I gripped her waist tightly and slammed into her from behind with powerful, relentless thrusts.
Her moans rang out sharp and filthy, echoing off the walls, her voice trembling as she cried out, begging me in a breathless, needy tone to keep fucking her thoroughly, to fill her even deeper.
When we were done, her pussy was leaking with thick, hot cum, dripping slowly down her thighs and staining the sheets beneath her.
I grabbed my cock, still slick and throbbing, and stroked it slowly, taking my sweet time before aiming it at her face and unloading the rest of my seed.
She took it all without flinching.
Even while pregnant with our child, she didn't hesitate.
She went as far as opening her mouth, taking my cock between her lips, and cleaning up every last drop of leftover cum with her tongue, slurping along the shaft, kissing the tip, licking off the residue like it was something sacred to her.
That's how our sex life has been.
Filthy. Deranged. Addictive.
The kind of thing that would send any normie running for their life just witnessing a single moment of it.
But for us? It was normal.
As I stroked her bloated, pregnant stomach lovingly, Manaka stared up at me with a strange tenderness in her eyes, a mixture of obsession, devotion, and something dangerously close to peace.
The results of the Holy Grail War? Forgotten.
Miyaka? Irrelevant.
All of that had been discarded from her mind.
She didn't care anymore.
All that mattered to her now was our child, our twisted little family, our home, and me.
She didn't even bother chasing Miyaka across the parallel worlds anymore, not because she couldn't, but because she chose not to.
In her warped, possessive perspective, she believed I was already entirely hers.
Mentally. Spiritually. Physically.
She had won.
There was no need to destroy the reality she had already molded into perfection just to satisfy a suspicion.
And the truth? She wasn't wrong.
I'd stayed with her for six months straight. I hadn't touched another girl. I hadn't gone out of my way to speak to anyone else.
No friends, no flings, no distractions. My entire world had narrowed down to her and Assassin, who mostly kept to herself.
That was all Manaka needed to be completely fulfilled.
Just the three of us in this sealed, depraved world where no one could interfere.
No one to stop us.
No one to judge us.
How could she have the heart to ruin it, when everything already felt perfect from her perspective?
So she smiled happily, as if victory was already certain and the future had been written in stone.
"What do you think we should name our future daughter, brother?" she asked me softly, her voice gentle as she stroked her belly with one hand while guiding my hand to rest there too.
"How about Anisphia Sajyou?" I said in a quiet voice, choosing the name of a character I knew from a yuri anime.
Secretly, I hoped our daughter would grow up to be as beautiful as her namesake and completely uninterested in men, except for me.
I thought that inwardly, of course. Manaka had no idea about those hidden thoughts, but she nodded, clearly liking the name.
"In that case, let's name her Anisphia Sajyou in the future, brother," she murmured, her eyes half-lidded with tenderness.
"Now, take me to bed… hug me. I don't want sex right now. I just want you to hold me."
I nodded without hesitation. I scooped her up into a princess carry and carried her into our bedroom.
There, I climbed into bed with her, wrapping my arms around her naked body from behind.
Our bare skin pressed together as we lay close, feeling the heat radiating from each other, our breathing slow and relaxed.
We closed our eyes and simply stayed there in silence, lost in the comforting warmth and softness of each other's embrace, the bond between us so deep that words weren't even necessary.
