That night, Rias gathered Akeno, Yumi, and Xenovia in her room. Now that they were living under the same roof, there was something they needed to discuss.
"The reason I called you all here is simple—it's about Kazuki," Rias began.
A palpable tension filled the air at her words.
"Relax. I'm not here to blame anyone. Quite the opposite, actually."
"What do you mean, Rias?" Akeno tilted her head, confused.
Rias exhaled. Yeah, she'd have to spell it out.
"You've all experienced Kazuki's insatiable sexual desire, right? So let me ask you this—do you really think any one of us can handle him alone at night?"
"Ugh…!?"
The girls' expressions shifted instantly. Not surprising. Kazuki was a monster—a bottomless well of stamina that never ran dry, no matter how many times he came.
Rias herself had been pushed past her limits countless times, forced to climax over and over until she passed out by dawn. Just remembering those sensations made her lower abdomen throb with heat.
If they kept pushing themselves like Yumi and Xenovia had—fucking until they collapsed—their bodies wouldn't hold up. That's why, as Kazuki's women, they had to work together.
Once Rias finished explaining, the others reacted—
"Y-You're right… Kazuki's got that sadistic streak, too…" Akeno murmured, cheeks flushing.
"Seriously, he never stops, even when I beg…" Yumi pouted, though her thighs subtly clenched.
"I-I've been humiliated so many times… but—" Xenovia bit her lip.
"That's… exactly what makes it so good…" the three sighed in unison, their voices dripping with arousal.
Rias smirked. 'Yeah, they're already wet—just like me.'
"Anyway, handling Kazuki alone is impossible. Especially after battles. From now on, we'll take him on together whenever possible. And we'll consider expanding the Harem."
"Expanding? You mean… Koneko-chan?" Yumi asked.
Rias shook her head. "Not yet. She's the obvious candidate, but… she's still carrying scars."
"…Right."
Koneko's wounds ran deep—betrayed by her own sister. It would take time. But Rias hoped, prayed, that one day, the girl would heal… and smile for real.
Knock, knock.
The door opened, and two breathtaking girls stepped inside…
Rias, her flushed post-bath body wrapped in a plush robe, and Akeno, clad in a clinging yukata. Earlier, Rias had declared they'd all be sharing Kazuki's bed tonight, leaving him waiting in the bedroom, the same one he'd woken up in that morning.
Now, their steam-kissed allure stole his breath.
"Sorry to keep you waiting, Kazuki~♪"
"Fufu, our apologies, Kazuki~"
"Ah…"
As Kazuki sat on the bed, Rias draped herself against his left side while Akeno pressed close on his right.
"Kazuki… Mmm—chu~, chup, slurp~, chu~, mmnn~—"
Rias' lips claimed his, shifting from featherlight brushes to hungry pecks, showering him in kisses.
"Ahhn~, Rias, playing unfair♪ Kazuki, me too—mmph~… chu~, slurpp, chpa~… nn, lewd, lewd~, chub~, slurpp~, mmm~… fufu♪"
Akeno stole Kazuki from Rias, plunging into a feverish kiss—tongues tangling, saliva mingling, wet ~picha picha~ sounds filling the room as their arousal spiked.
"A-again, Akeno… Kazuki's lips are mine—mchu~, chub~, slurpp~… jlurp~, mmm~… gulp, gulp~, mmph!"
"Ara ara, Rias~!! Very then I'll simply… take this instead."
As Rias reclaimed Kazuki's mouth, Akeno's gaze dropped lower, to the throbbing tent in his pants.
"—My, my~!"
She tugged down his boxers, freeing his erect cock. At the sight of its girth, her cheeks flushed, and a sigh escaped her lips. Wrapping her fingers around the shaft, she began stroking.
"Nngh… Rias, Akeno…!"
Trapped between Rias' assault above and Akeno's below, Kazuki moaned.
Encouraged, Rias slid a hand under his shirt, teasing his nipples, while Akeno's tongue swirled over his slick tip.
"Fufu♪ So boys do feel good here too… chup~ How does it feel?~"
"Mmhh~ sloshh~, slurp~, slurp~… Ahh, so hot, so hard… perfect!!"
"Guh—you two…!"
"Hmm? Are you about to cum? In that case... Akeno."
"Slurpp~, mm~… Yes, Rias."
At Rias' signal, Akeno nodded, loosening her yukata to bare her voluptuous chest.
Rias shed her robe, revealing flawless skin, then knelt opposite Akeno beside Kazuki's hips.
And then—
"Guh!? R-Rias... Akeno... Ughh—!!"
Kazuki's thick cock was enveloped, squeezed, and rubbed between Rias and Akeno—between four voluptuous, massive tits.
"Sniff, sniff... Mmm~! As strong as ever... Slurp... Fufu, but so delicious♪."
"Ufufu Kazuki-kun, you're getting even harder... Nnnh, it feels good, doesn't it? That's right, just let yourself feel even better..."
Rias's firm, rocket-shaped mounds and Akeno's soft, bell-shaped breasts pressed tightly around Kazuki's cock, stroking him relentlessly.
The lewd, wet sounds of their slick movements echoed through the room, the scent of pre-cum mixing with the intoxicating musk of their arousal.
It wasn't just Kazuki's heat—the pheromones of the two lust-drunk women only amplified the sinful atmosphere, setting all three of them ablaze with desire.
"Aah! Rias, Akeno, I-I'm...!"
"Ah, you're close, Kazuki? That's fine... Cum whenever you—Mwah—want..."
"Mmm, go ahead... Cover our breasts with your thick, hot—Slurp—load..."
With lips and tongues teasing the tip protruding between their cleavage, Rias and Akeno worked in tandem, pushing Kazuki toward the edge.
And then—
"Guh—ah! C-Cumming!!"
Splurt! Splurt-splurt! Spurt—gloorrgh!!
""Haaahhhhnnnnn~!!""
Like a volcanic eruption, thick white magma rained down upon Rias and Akeno.
Drenched in the scorching, milky warmth across their faces and tits, the two girls let out euphoric moans.
"Mmm… slurp… Ahh, how wasteful, Rias… lick~…"
"Nnn~♪ Akeno, you're already… slurp, lick~… gulp"
For a moment, Rias and Akeno sat dazed—but soon, they began lapping up the sticky mess splattered across each other's bodies.
Their tongues trailed over foreheads and cheeks, slurping up the pooled semen between their breasts before swallowing with lewd, satisfied gulps.
Before the two blissful girls, Kazuki's still-hard cock stood tall.
"Clean me up, both of you."
Despite his recent release, his shaft showed no signs of softening. Smiling, the two girls obediently licked and sucked, polishing every inch until not a drop remained.
Once his cock was spotless, Kazuki lay back on the bed.
"Akeno."
"…Yes~!"
Hearing her name, Akeno responded eagerly, crawling closer to him.
"Can you take me in yourself?"
"…I'll try."
Swallowing hard, Akeno gripped Kazuki's thick cock, aligning it beneath her pussy before slowly lowering her hips.
The moment his tip brushed against her dripping slit, a lewd squelch echoed, making her waist jerk reflexively.
"…I'm putting it in now~"
"Yeah."
Akeno sank down onto his throbbing cock with one lewd splashh.
"Nnngh! A-Ahhh~~, ahaahn!!"
With a wet sluuurp, the burning heat filled her depths, forcing a wanton cry from Akeno's lips.
Guided by her overflowing love juice, Kazuki's dick reached deep inside, tapping against her cervix. The sensation of her walls being stretched wide sent conflicting waves of pleasure and pressure coursing through her.
"Can you move, Akeno?"
"Hahh… hahh… Nngh! I-I'll try… pant… Uunh… Nngh, ahhn~!!"
Akeno Himejima rocked her hips, pulling back until his dick nearly slipped free before plunging down again.
Being her first time in this position, she occasionally lifted too far, nearly losing him, but soon, she found her rhythm. Her movements grew smoother, faster, more confident.
"Haah… ahh… Nn… Good… It feels so good…!"
Bracing her hands against Kazuki's abdomen, Akeno moved in a steady tempo, sometimes rolling her hips to adjust the angle, seeking the spots that made her shudder.
Unlike their usual pace, the cowgirl position allowed her to move at her own pace—something Akeno found incredibly easy and pleasurable.
Meanwhile, Rias couldn't tear her eyes away from the shameless display between her lover and her best friend.
She understood the mechanics of sex in theory. But the scene unfolding before her was far more obscene and raw than anything she could've imagined.
Akeno, straddling Kazuki and moving her hips with reckless abandon, looked so utterly debauched that Rias could hardly recognize her usually composed friend.
"Ah… Nn… Haa, haa… I-It's incredible… both of you~!!"
Before she realized it, Rias found herself staring at their lewd act while her fingers trailed down to her own dampening thighs.
Kazuki Fuwa looked up at Akeno with satisfaction as she rode him.
Her long black hair swayed with every motion, droplets of sweat scattering like pearls, carrying her sweet scent through the air. Her massive, melon-like breasts bounced enticingly, while her soaked folds clenched around him with perfect tightness.
Seeing her look down at him with that seductive smile, Kazuki felt a surge of affection—until he suddenly sensed another pair of eyes on him.
"Haa… haa… Nn, ahh…~"
There, watching him intently while fingering her dripping pussy, was Rias Gremory.
Her face was flushed, her expression a mix of envy and frustration as she stared at them.
Noticing this, Kazuki smirked and called out to her.
"Come here, Rias."
Hearing his command, Rias crawled toward him on all fours. Hesitant and unsure, she looked at him questioningly until Kazuki guided her.
"Rias, come closer… Yeah, just like that. Put your legs over here."
"Eh…?! K-Kazuki, this is so embarrassing…!"
Ignoring her protests, Kazuki pulled her down until her glistening slit hovered right above his face. The obscene sight of her dripping folds was too much to resist, and he immediately buried his tongue in her pink, virgin pussy.
"Nnhaaaahhnn~!!"
He traced her slit with his tongue, lapping up her sweet nectar, then pushed a finger inside while gently nibbling her swollen clit.
Overwhelmed by the sensation, Rias bucked her hips, nearly smothering Kazuki's face with her pussy.
"Ah, ohh… K-Kazuki…! R-Right there, nngh~! I-I'm… I'm cumming—Haaahn~!!"
With just a few strokes, Rias came undone, her juices splashing against Kazuki's face. Unfazed, he continued eating her out, savoring every drop.
"Ahhn~! Pwaah! Kazuki, Kazukii…! I-I already came… P-Please, let me rest…!"
"No."
"Aahhn~! S-So mean~!!"
With a lewd squirt, Rias let out a high-pitched moan, torn between pleasure and overstimulation. As her legs gave out, Akeno caught her before she collapsed.
"A… Akeno…?"
"Fufufu~ You looked so cute when you cum, Rias~!"
"M-Meanie…"
"Hehe~ Now, let's make you feel even better, Rias."
"Akeno? W-Wait… Nn, haa… Ahhn~!"
Akeno interlaced their fingers, then resumed riding Kazuki while pressing her voluptuous tits against Rias's. Their hardened nipples brushed together, sending waves of new pleasure through them both.
""Nngh— AAAAAAHHHHHHHH~~~!!?""
Rias and Akeno cried out in unison as pleasure surged through them from both above and below.
"Ah… Akeno…"
"Rias… Nn—"
Before they realized it, the two had succumbed to the twisted atmosphere, their lips meeting in a heated kiss…
