Volume 9 Chapter 34 (Interlude 4 – Part One) Ufufu, So You Want to Taint Your Big Sister ★
Edited by: Kanaa-senpai
Shiori-chan had always been a girl who created as many “forbidden” drugs as she did ones meant to help humanity. Once, she’d even brewed up a pill that stirred wicked desires in the body—thankfully without any side effects.
And then there was one even more dangerous: “When you’re about to execute a prisoner, give her this. It’ll make her feel so good it becomes her last happy memory. But if she doesn’t get a c…k right away, she’ll go mad. So as soon as you administer it, you must violate her.”
That drug—the “Ecstasy Pill: Extreme Effect, Extreme Side Effect”—was one she had personally invented.
It had actually been used before, during the assault on Sheryl and Stella.
That was something I could never allow myself to forget—our criminal acts against those girls.
And now, McGaref’s idol and mad scientist, Shiori-chan herself, had finally succeeded in making a safer version—a pill with no side effects at all.
”So this is your new ‘pleasure pill’?”
”Mm-hm! Unlike the old one, it’s safe. No side effects, so you can make a girl mo…nn as much as you want without hurting her. That’s why… if you’re willing, Takumi-kun, I’d love for you to test it on one of my classmate-slaves.”
And so, I walked straight into Shiori-chan’s trap. Under the guise of “testing,” I ended up turning one of our class idols into a receptacle for my seed.

When Shiori-chan finally collapsed, twitching like a frog, eyes rolled back in bliss, I gently covered her with a blanket. Then I stared at the two vials she had given me, wondering who I should use them on.
Her voice had been loud—too loud, even compared to the other girls. She’d screamed in that filthy, debased o…hh voice that echoed in my ears long after. There was no doubt the drug had worked.
The problem now was: on whom would it work best?
Most of my</igirls were already highly s…xual. Hikari-chan, Aria—the top two. Plenty of others, too.
But then, there were two exceptions.
One: the woman who seemed</ilike a predator, but was in fact a healer at heart.
And the other: the pure one who had never shown me that kind of debased breakdown.
I could hardly resist. I summoned them to my chamber that very night.
* * *
”Ufufu, I’m so glad you called us. Tonight, you want to eat up both me and my little sister, don’t you?♡”
”I’m nervous… serving together with Natalie-neesama like this. But I’ll do my best, onii-chan. Please reward me with your s…men, okay?♡”
The ones I chose were the princess sisters: Ms. Natalie and Eil-Eil. Tonight, they wore Aria’s custom-made uniforms. On Eil-Eil it looked scandalous, like a crime. On Natalie, it turned her into a blonde, busty cosplayer. In short: both were irresistible.
Natalie, being a seasoned courtesan, always took me with composure. She had never truly been reduced to a screaming, writhing mess. Eil-Eil, meanwhile, always held back—different from Mori-Mori, who begged shamelessly for harsher training.
But honestly? The combination of my most mature slave (Natalie) and my least (Eil-Eil) was intoxicating. And now, with this pill that could force out o…hh cries? Tonight was the night.
* * *
”My, Takumi-san. You’ve already made your c…k so hard for us♡ A fallen princess like me can only spread her legs and take it♡”
”Onii-chan… it’s so big. You’re really going to f…ck both our pu–ies with this, aren’t you? I don’t care if I was a princess. I’m your slave♡”
They spoke without shame, stoking the fire inside me.
At once, they set to work: Eil-Eil took my shaft into her mouth, while Natalie pressed her lips to my a–s, licking obscenely.
”Mmm… Takumi-san’s back hole… it tastes of humiliation, and it’s so sweet. Reminds me that I’m a courtesan. I want to keep licking forever♡”
”Onii-chan, your c…k tastes so good. I’m so happy you let even a former princess like me service you this way♡”
Their words alone could have undone me. Green-haired Eil-Eil, flat chest bared, bobbed her head diligently, while Natalie—who should have been robed in silks and jewels—was on all fours, debasing herself as my slave.
As a man, how could I not be aroused?
* * *
”By the way, onii-chan. Aren’t you going to use that pill on us tonight?”
I froze. So they knew.
Of course—they lived with Shiori-chan. Secrets never lasted there.
”Y-yeah. But she swore it has no side effects. She tested it herself.”
”Thank you. Then, onii-chan, you can break me as much as you like. Whatever you do, I’ll accept it gladly.”
”And me as well. If there’s something you want to do to your classmates but can’t… use me instead. A fallen princess is perfect for that, isn’t she?”
Natalie pressed her soft breasts into my back, licked my neck, and nipped my ear.
”Imagine it, Takumi-san. Eil-Eil was supposed to become a courtesan, just like me.”
”Yes… I was meant to be trained to serve, too.”
I already knew. But hearing them say it, smiling sweetly, sparked forbidden fantasies. Natalie stroked me slowly, feeding that lust.
”My sister would have knelt before strange men, taken their c…ks into her mouth, spread her legs for their s…men. That was the path awaiting her.”
”And I… accepted that fate, letting my virginity be sold for our people, for the children, for atonement.”
Natalie’s words stoked my jealousy and desire alike.
I could almost see it—Eil-Eil waiting in a dim chamber, bowing to men not me, wrapping her lips around someone else’s shaft.
”Do it, onii-chan. C…m on my face. Mark me as yours.”
”I’m going to—ahh…!”
Hot release spurted across her cheeks.
”Ahh… it’s so warm. You gave me so much, onii-chan♡”
”Mm, wonderful. You’ve defiled us—two fallen princesses bathed in your s…men.”
Natalie coaxed the last drops out with her hand, smearing it on her fingers, and Eil-Eil licked them clean.
The sight made my heart pound.
Even cast down from royalty, even reduced to courtesans, their dignity still shone. And I wanted nothing more than to drown that light in my seed.
* * *
”Then, it’s time. Drink the pill.”
”Of course. Make us scream, Takumi-san. Watch us fall apart for you♡”
”I’ll show you my most embarrassing side, onii-chan. Please don’t hate me for it♡”
They each took a pill into their mouths. Then, with a deep kiss, the sisters shared it between them.
It was beautiful. And it made me harder than ever.
