Ryouma Sajyou's POV
Afterward, I ordered Assassin and the servant I'd recently summoned to trail Caster and his master, after I'd gotten fresh intel from Manaka.
Right after giving the orders, I was on top of Manaka, slamming my cock into her pussy while holding her in a tight mating press.
Her legs were folded back against her chest, her ankles hooked over my shoulders as I pushed my cock deeper and deeper inside her slick, clenching hole, with my balls slapped wetly against her ass.
I loved breeding her. Every time she moaned, gasping and trembling as she took my entire length, I felt my blood boil.
The way her pussy sucked me in, squeezing around me like it never wanted to let go, drove me insane.
And every time I shot my cum into her, it only made me want to fuck her even harder.
I couldn't help but speed up, my hips snapping forward as I fucked her aggressively, pounding into her cunt over and over while my cock pulsed and spilled my seed inside her.
I kept pumping my cum into her until I felt my balls drain, emptying myself completely as we both crashed into a powerful orgasm at the same time.
Earlier, we'd already been at it for hours. The entire room was drenched in sweat, the sheets tangled and damp beneath us.
The air was thick with the raw, musky scent of sex, clinging to our skin and hanging heavy around us as Manaka finally slumped forward, her body trembling, and leaned her flushed, exhausted face against my chest, panting for breath.
"Brother, you came so much inside me… do you want to knock up your own sister?" Manaka murmured breathlessly, her voice trembling with lingering lust.
She caressed her belly lovingly, her eyes shining with a mix of desire and soft, dangerous affection.
Her stomach was still swollen and slightly bloated from how deep I'd cum in her.
Every second, it grew a little flatter again as my thick seed slowly leaked from her womb and trickled out through her pussy lips.
I stared at her flushed pink folds, slick and glistening, dripping with milky cum that oozed out and stained the sheets beneath her thighs.
It made everything so fucking hotter.
"This time, you should keep it, sister," I growled, my hand joining hers as I stroked her soft belly with possessive, gentle fingers. "I want you pregnant with my daughter after the Holy Grail War."
She froze for a moment, eyes flickering with hesitation, her lips parting as if unsure how to answer. "Isn't that too early, brother?"
"I don't think so." I leaned closer, biting her ear gently, my teeth grazing the sensitive skin until she shivered. "Don't you want my child too, sister?"
Her breath hitched as her cheeks turned an even darker red.
She stared at me with a shy yet desperate glimmer in her eyes, trembling as the thought took root.
"Brother… I want it. I want your child. Please make me pregnant… love me, fill me," she whispered, her voice barely more than a needy whimper.
"As you wish, my princess." I chuckled low in my throat and leaned in to crash my lips against hers.
We kissed hungrily, tongues tangling, tasting each other's lust.
Moments later, she climbed onto me, straddling my waist as her wet pussy hovered over my cock, which was already standing rock hard again.
Slowly, she lowered herself onto me, inch by inch, swallowing my entire length until her hips met mine.
Then she started to ride me, bouncing and grinding her hips in a rhythm that drove me absolutely fucking insane.
Her pussy squeezed around me so tight that every time she lifted her hips, I could see strings of sticky cum stretching between us before she slammed back down, taking me deeper each time.
The sounds of wet slaps and messy squelches filled the room as she fucked herself on my cock, her eyes rolling back, sweat dripping off her flushed skin.
I couldn't get enough of her.
The more I thought about it, the more the image of her pregnant with my child burned itself into my brain, her belly round and swollen along with her nipples, her cunt tighter, begging me to fuck her even when carrying my baby.
I couldn't help myself.
The thought made my cock twitch harder inside her as I gripped her hips and thrust upward, meeting her bounce with savage power.
The more I thought about her bloated belly heavy with my child, the more I couldn't let go, and I kept pounding my sister wildly, emptying load after load of hot, thick cum deep into her womb.
This time, I held absolutely nothing back.
