Kazuki took her hands and lay back, shifting them into the cowgirl position, and then began pistoning up into her from below.
"Hahnn, ahn, ahfuu, ha-ohnn. No, if you go this hard, I'll let it out again..."
"Go ahead. Your voice, your squirt, your piss... Let it all out in front of me, Nee-san!"
At Kazuki's words, a shudder raced down her spine, and her pussy clenched tight. And then—
"Aaaaaaaahhh!! I-I'm cumming! Everything's coming out!!"
Splurt! Splurt! Splurrrrt!!
Bathed in the semen flooding her womb, she climaxed simultaneously, spraying both squirt and piss everywhere, drenching Kazuki's face and stomach indiscriminately.
"Ahah... ahahahaha."
Reeling in shock, she laughed—a dark, twisted ecstasy, far beyond mere orgasmic bliss, at having soiled something so precious.
'Oh fuck!!' The sight of Serafall's face contorted in shame and humiliation as she came and lost control of her bladder was so erotically, adorably lewd that Kazuki had unilaterally launched into round two.
Even during the second round, when she gushed out both her squirt and piss spectacularly, Serafall was still erotically cute as fuck. But then, large teardrops began spilling from her eyes, and Kazuki hurriedly sat up.
"Sorry, Nee-san! Did you hate it that much?"
"Sniffle... Hate? Hate what?"
"I mean, I went ahead and came inside you again for the second round without asking."
'Shake, shake.'
"It's not that I hated it. But... I'm sorry."
"Huh?" The conversation wasn't matching up. He'd thought he was the one who should be apologizing...
"What's wrong, Sera-nee? Why are you apologizing?"
"Because... I peed all over Kazu-kun... If I do this again... you'll hate me!"
'Again? What did she mean by "again"?' Setting that aside for the moment, he decided to soothe her, pulling Serafall into his arms and gently patting her back.
After a while, she seemed to calm down, and haltingly, she told him the reason behind her tears.
Listening to her story, Kazuki moved past bewilderment straight into pure, unadulterated fury.
That man despised her, showed contempt, and just left—because the girl he loved wet herself a little? And on top of that, with a parting shot of "That's filthy!?"
'What a goddamn moron!!'
This was Serafall, Serafall Leviathan! A Satan who combined top-tier beauty and strength among all devils, who commanded popularity surpassing any idol! Her piss was basically a fucking reward!!! 'Purely Kazuki's personal opinion.'
But at last, he understood. Unwittingly, having sex with him must have triggered her trauma.
Kazuki truly didn't mind at all, but given how deep her trauma seemed to run, what should he do? No—he was always clumsy with words anyway. If so, he'd just follow his heart and take the plunge.
Petting Serafall's head as gently as he could, he spoke.
"Thank you for sharing something so painful... But maybe I ought to thank that bastard?"
"Eh!?"
Serafall's eyes went wide with shock.
"Because if he'd accepted you, Nee-san, he'd probably be your husband right now, and I might never have gotten to be with you like this."
"Now that you mention it... maybe you're right."
When he said it with a smile, she returned a faint smile of her own.
"Nee-san, I don't mind if you pee on me. No—honestly, it's more like a reward."
But when he said that, her face twitched. 'What now?'
"I see... Um, Kazu-kun, do you... have that kind of kink? Are you maybe... a pervert?"
Realizing he'd screwed up from the way she asked so timidly, he knew he had no choice but to plow through with sheer momentum.
"Damn right I am. Every single guy out there is a pervert, no exceptions. So, Nee-san... I can say this with absolute certainty! Whether you wet yourself or piss all over me, I will never, ever hate you for it!"
He declared it with unshakable finality.
When Kazuki suddenly came out to her as a pervert—and moreover claimed that was precisely why he'd absolutely never hate her—Serafall was so stunned she went blank. What utterly absurd logic. And yet, strangely, the gloomy feelings from just moments ago were washed away, replaced by a rising bubble of laughter.
'Honestly, this boy... If he wanted to comfort me, he could've put it a little better...'
Clumsy, yet kind—she loved him for it so much she could hardly stand it.
"Hmm. So Kazu-kun would absolutely never hate his Onee-chan?"
When she asked in a teasing tone, Kazuki gazed straight at her and reached for her head.
"That's right. Because—"
He untied her ribbon, and the hair that had been pulled into twintails cascaded down her back like a waterfall. Kazuki took a single lock of her hair in his hand, handling it as though it were a precious treasure.
"—ever since the first time I saw you like this, Nee-san... I've been in love with you..."
He pressed a gentle kiss to that lock of hair.
Thump!!
In that instant, her heart pounded violently.
'Eh? No way? Oh no, my face is burning up! No, not just my face—my whole body's on fire! Eh? Wait just a minute!? Why does my chest feel so tight? Like it's being squeezed... Aaah, geez! This loud thump-thump-thumping since earlier is so annoying! Quiet down, my heart!!'
She knew this feeling.
This sense of security, as though every last part of her had been accepted. This euphoria, as though she'd been forgiven for everything. This feeling of omnipotence, like she could do anything right now.
A feeling she had long ago given up on ever experiencing again—she remembered it, and now, she understood it with devastating clarity.
She, Serafall Leviathan, had fallen in love with Fuwa Kazuki.
Without warning, Serafall threw herself into Kazuki's arms. Startled, Kazuki wrapped his own arms around her back in turn, holding her tight.
How much time passed? Serafall began giggling softly.
"What's up, Sera-nee?"
"Hehe, nothing. I was just thinking how easy I am. I mean, such a cliché confession, and my heart's pounding so hard I can barely believe it, and I feel this incredibly happy... Honestly, I'm like the heroine of some old shoujo manga."
"Sorry for the cliché confession. But I was just telling you honestly how I feel."
"That right there. That's exactly what I'm talking about, you dummy."
Their gazes met, their faces drew closer, and naturally, their lips pressed together.
"Nn chu, Ufuhn, mm... Ah, nnfu chupu, chu... Afuhn, nnah... chu... Nn, I love you."
Serafall's tongue moved like a living creature, slithering across Kazuki's lips, tangling with his tongue, tracing his teeth, pouring in her saliva. With each movement, wet, lewd slurping sounds filled the air.
