Chapter 583 Double Ero-Ero Onee-San ②*
Edited by: Kanaa-senpai
The breeding season had finally begun. And the first match of the season? My beloved receptionist Marm-san and my dear catgirl Suu-san—my two onee-sans, whose ero-ero game was on point. …Well, to be fair, Suu-san had probably been ero-ero from the very start.
”Hands and mouths over here, nyaa~♡”
”That’s right, Kento-kun. No moving now, okay? ♡”
”Mmmph…”
Marm-san straddled me, my body reduced to jelly by the oil massage, while Suu-san rubbed her pillowy-soft breasts across my face. It seemed their plan was to pin me down and squeeze out every last drop of my seed.
At first, the whole thing had supposedly been about not pushing me too hard. But I had a sinking feeling I was about to get utterly wrecked. Sure, if I didn’t have to thrust, I’d conserve stamina—but my d**k was in serious trouble.
”Nn… haaah… haaah… ♡♡♡”
”Gghhh…!”
My “D**do-Buddy,” now ultrasensitive thanks to that oil massage, was currently engulfed by Marm-san’s slick, seething p**sy—which, judging by how worked up she seemed, had also benefited considerably from the treatment.
”Fufu, feeling good~♡? You can go ahead and leak whenever you want, okay…? ♡♡♡”
I’d thought I’d blow the instant the tip touched her entrance, but instead, a heat more intense and overwhelming slammed into my entire d**k. Her abundant juices, the squirming folds, the clamping grip of her v**inal walls and entrance, the cervix that seized my glans and refused to let go, the uterine mouth that sucked me in.
Each part of Marm-san’s v**inal opening attacked my “D**do-Buddy” in its own way. At this rate, I’d pop off without even getting in a single stroke—let alone three and a half. But that wasn’t all…
”Hehe. The way you’re clinging to me is just adorable… ♡ Should I call you ‘Kento-kun’ too? Nyaa~♡?”
”Ahaha♡ Your little weenie is twitching inside my onee-san p**sy…♡ Is it really that good, Kento-kun♡?”
The two of them were leaning way too hard into the onee-san act. No question about it—one of my wives had sold me out. Though, honestly, it was probably ten-to-one that my love-slave Lily had put them up to this. And my weakness for onee-sans was already pretty much common knowledge anyway.
Still, their assault was devastatingly effective. My thing for beautiful onee-sans was practically etched into my cells at this point—it was instinct. When they gazed down at me with those dreamy eyes while their v**inal openings squirmed ferociously, or when they became my human pillows to help me endure the pleasure… I was helpless.
On top of that, they kept murmuring “Kento-kun” in those gentle voices, and Suu-san even fussed over me, petting my head. Being attacked by onee-sans from above and below was basically my kryptonite.
”Gwaaah…!”
”Ah… ♡”
”Huh?”
SPLURT-SPLURT-SPLURT!! ! ! ! SPLURT-SPLURT—!! ! ! ! SPLURT——!! ! ! ! SPLURT——!! ! ! !
So, it really couldn’t be helped that I leaked. …It simply couldn’t be helped. Yes, it was mortifying, but there was nothing I could do about it. Marm-san was rubbing her lower belly with a dazed look, while Suu-san seemed slightly startled. Both hit me in ways I couldn’t quite articulate.
”Did he actually come already?”
”Mmm♡ A whole lot, too… ♡♡♡”
”Just as Lily-chan said… I never imagined Lord Harvest… that Kento-kun could become this weak… ♡”
”Ufufu♡ At this rate, we can probably get even more out of him… ♡ I mean, he’s still rock-hard… ♡♡♡”
It might have been casual chatter to them, but even that got a reaction out of me. Two onee-sans, discussing how to milk me dry. They were practically giddy with excitement.
”Fufufu, Kento-kun, thank you for leaking so much~♡ And when you feel like letting go again, anytime is fine, okay~♡? Do your best and knock your onee-sans up… ♡♡♡”
Marm-san leaned over me, completely unguarded. Her red hair cascaded down, and her scent tickled my nostrils. She didn’t need to tell me twice. If she wanted to milk me so badly, fine—I’d give her everything I had.
If things kept going like this, my reputation as a “lady killer” would be ruined. I reached out for the voluptuous, dark-skinned Boob-sama dangling right in front of me. But…
”I believe I told you no touching? Bad! ♡”
My hand was caught by Suu-san, my resistance cut off before it even began. Grrr… Normally, I could turn the tables easily, but today seemed different. Against a beast-kin’s strength, I didn’t stand a chance.
”Thanks, Suu-chan. He really is a handful, isn’t he?”
”Don’t mention it, Marm-san. Stay on your guard. He seems docile now, but we both know his true nature.”
What am I, a wild animal…? I wanted to retort, but there was no time. The two of them immediately launched an attack on both my ears.
”You don’t have to rush. We’ll make you feel so good… okay? Just be a good boy, Kento-kun♡”
”Fufu, that’s right. Leaking isn’t anything to be ashamed of. Let it all out and knock us up… ♡”
From the right and the left, they whispered in sweet voices while dragging their tongues along my ears. Back in my original world, this would’ve been a “real-time dual-ear-licking ASMR experience” or something. Inside and outside my ears, right down to my brain—it felt like everything was being tickled… Pleasure? It was ticklish? Either way, resistance was futile, and my body went limp again even as it grew more sensitive.
Mwah, slurp… ♡ Come on, leak for us♡? Felt good when you leaked before, didn’t it♡? Mmm, mwah…♡ Right♡? Leaking into your onee-sans’ wombs, doesn’t it feel amazing♡? Leak, leeak♡
Slurp, mwah…♡ Kento-kun when he leaks… was so cute…♡ Mwah, mwah…♡ Show us more♡ Our adorable Kento-kun…♡ Leak, leeak♡
Pressed close against me, they attacked with words, tongues, and lips. Everywhere was soft and smooth, and the oil only made their bodies cling tighter. The weight of their female forms pressed gently against my limp body. Meanwhile, Marm-san’s v**inal opening continued to cling to my oversensitive d**k.
Slurp, smack…♡ It’s okay…♡ No matter how pathetic Kento-kun’s leaks get… we know all the cool parts of you too…♡♡♡
Mmm, lick…♡ That’s right♡ Even if you lose today, it’s okay♡ So go ahead and leak a whole litter of babies into us♡♡♡?
They could sense my weakness and mercilessly whispered sweet temptations. When had they learned these techniques…? I could feel the thought creeping in: Maybe it’s okay to lose just this once…
…But no. Could you really call it true baby-making if it was all about the d**k? No. I had an obligation to properly prepare the womb that would bear my children.
Exposed to a two-front onee-san assault, I resisted with sheer willpower and love for my future children. I focused my strength into my lower abdomen.
”Nngh♡♡♡! ? W-Wait, Kento-kun, no, you can’t—♡♡♡! “
”Oh my, such a little rebel… Nyaaaah♡♡♡! ? “
Simultaneously, I twisted around and bit down on Suu-san’s cat ears. They tried to compose themselves, but their “onee-san” facade was cracking. I seized the opening and grabbed a fistful of Marm-san’s jiggly Boob-sama, crushing her n**ple. I shoved my hand between Suu-san’s thighs and rattled her insides.
Even against two-on-one, I’d faced off against the absolute pinnacle of erotic onee-sans—Mother Marian herself. I wasn’t about to lose to this. …Even if I had already leaked once, and it was a close call.
”Uohhh, ohhh, ohhh…♡♡♡”
”S-Slurpy…♡♡♡”
Soon enough, the two of them collapsed onto the bed side by side—and the counterattack had begun.

Summary:
The breeding season has begun, and Kento finds himself pinned by Marm-san and Suu-san in a coordinated onee-san assault designed to milk him dry. Despite his initial surrender to pleasure, he reasserts control by biting Suu’s ear and grabbing Marm’s breast. The counterattack has begun, though the two women’s affection for him remains evident even as they collapse onto the bed.

Translation Notes:
Notes:
• Marm – The attractive, red-haired, tanned receptionist at the Adventurer’s Guild. She wears a uniform that emphasizes her ‘nice body.’ She is kind and acts like a supportive ‘big sister’ figure to Kento. Looks like Mirajane Strauss from certain series.
• Suu – Secretary for the Royal Capital Beast-person Mutual Aid Association and a cat beast-person. Sample No. 19 in Kento’s report. She steps up as the first witness for the defense. Wears glasses and a tight suit.
• Kento – Lord Harvest, a reclusive, dark-haired Northern Continent viscount and young isekai inventor, resembles a salaryman. Bound to the Queen, he runs a magic shop and tavern, crafting adult goods; though weak to erotic things, his gear makes him immune to Succubus charms. He created the Ddo-Buddy and Slime-Pal weapons. Analytical yet easily swayed, he is pampered by subordinates, shares a quiet bond with Amelia, corresponds with Meryamisha, and is pragmatic with guests like Nada.
• Lily – Jin’s pink-haired, blue-eyed experiment slave and wife, pregnant with her second child. A Harvest shop slave, primary test subject, and secret magic user, she serves as Kento’s love-slave (evoking comparisons to Nada’s behavior). Energetic and expressive with V-signs, she watches repairs, tends the Dildo-Buddy Mansion garden, and informs the protagonist—who calls her a wanton—on domestic and political matters.
• Harvest – Viscount Kento Harvest, a gaunt lord from a prominent line, is a pragmatic former adventurer and diplomat clad in a tattered academic coat. This royal mentor leverages Earth tech and noble authority while managing a magic-circuit shop. Proactive with numerous lovers, his expertise is now requested by Unia, who is curious about his merchandise.
• Marian – Canarias convent Mother Superior and Church of Demon-Subjugation’s strongest Ascetic Faction nun, she helped neutralize the Succubi threat. This busty, provocative mother figure sports wavy purple hair, a tear mole, a Monroe walk, and a black habit. Obsessed with Alex-kyun, she uses supernatural vaginal control and aggressively pesters Kento about the Devil’s Stick.
