Chloe coming to find Iris was all well and good.
As expected, the two quickly became close, and by the time they returned from their outing, they were like sisters, much to Sirius's delight. But there was one regrettable thing about it...
Their conversations always revolved around "Dirk Ruin."
Morning, noon, and night...
Chloe and Iris chatting endlessly about Dirk Ruin.
It naturally started with Iris, but Chloe seemed genuinely interested in him too. It was because of his unique background studying medicine in the East and his un-doctor-like behavior of always putting patients first. Every time she heard stories about him, she'd clap her hands and exclaim, "Wow, he's that amazing?!" But Sirius wasn't thrilled about it at all.
He found himself naturally jealous of the doctor.
Sure, the guy was impressive, and he'd cured Iris's illness...
...But was that really such a big deal?
Wasn't he, who'd turned a no-name merchant guild into a nationwide powerhouse, even more impressive?
The jealousy and irritation grew day by day. For the first time in ages, Sirius felt annoyed enough to grab an artifact. Everyone had their flaws—no way a guy like Ruin didn't. In his anger, Sirius secretly followed Iris without her knowing. He didn't particularly want to see his little sister's naked body... but to catch the guy's weakness, he had no choice.
"Got it. So, how about a kiss first?"
"Oh? You're being unusually forward today."
"Someone got me a little mad."
"Oh my, Mr. Ruin... Are you jealous right now?"
"Yeah."
"Heavens, jealous over a woman... Hehe, do I mean that much to you? I'm thrilled... Mmm, chuup... Churu, chuup... Haah, I'm glad I got close to your sister."
"Must be nice. Getting called 'sister' and all."
"R-Ruin! What's with you today... You're too cute! Chuup, chuu... Haah, should I call you big brother too, Ruin big bro? Or maybe... oppa? Ruin oppa? Hehe..."
But what the hell was this...?
Something unimaginable was happening.
Ruin casually using informal speech, and Iris calling him "oppa" while pressing her lips to his... No, even tangling her tongue with his. What was this? Were they dating or something? Sirius bit his lip in betrayal. He'd never heard "oppa" from her before. And for that guy to hear it first...
Sirius trembled with rage.
But he could only rage alone.
Oppa or not, his little sister had started kissing and slyly moved her hand to undo the man's belt. Then, with practiced ease, she pulled down his pants and underwear... This wasn't her first or second time. Iris knew how to undress a man. And that... stroking the tip before gripping it and stroking back and forth... Ahh...
His little sister knew how to satisfy a man.
Sirius clenched his fist at the realization.
That damn bastard... Had he made her do this under the guise of treatment?
"Churp, puha... Haah, oppa's cock... It's so hard now..."
"Iris..."
"Hehe, you like being called oppa that much?"
"Yeah... It's the best."
"Got it. From now on, when we're alone, I'll call you oppa."
Sirius, his fists shaking, looked at his sister's face and wore a defeated expression. Iris giggling as she looked up at Dirk Ruin. It didn't seem forced... She was enjoying it. Sirius bit his lip again. His sister poked at the cock teasingly before starting a full handjob.
An unimaginable disgust washed over Sirius.
But that handjob was just the beginning of the day's events.
"Oppa, haah... Ruin oppa... Feels good?"
"Yeah, it does... But can I ask a favor?"
"Hehe, sure... Guess I'll use my mouth too."
"You okay with that?"
"Of course. It's what we always do... Hehe, smooch... Haaam, jjuup, jjurup... Puha..."
She knelt down into a humiliating position. Opening her small mouth with an "aaang," she swallowed the doctor's cock leaking precum. Then, looking up at him again, she sucked noisily... Damn, a wave of something worse than disgust hit him. His little sister's fellatio was the worst.
The lewd acts of his once-innocent sister.
When did she get this slutty?
Her expression was downright lascivious.
Especially while sucking cock.
Sirius was seeing, for the first time in his life, the face of a "bitch in heat."
Even as a patient, she hadn't been this bad, but now Iris was different. She kissed the cock carefully before bobbing her head vigorously. Lewd sounds and a filthy smell wafted over—the stench you'd only smell in a brothel. And now... it was coming from his little sister. Sirius's face twisted.
"Jjuup, jjup... Puha, churup... Jjup, chuup... Puh..."
"Sorry, Iris. Just gonna use it a bit."
"Mm?! Mmph... Mmmp, mmph... Mmph! Mmph!"
"Iris!"
"Mmmph! Mmph! Mmmp... Mmph..."
"Hoo... Feels so good..."
"Mmph, *cough cough*... Ruin oppa..."
But that damn bastard finally crossed the line.
Grabbing Iris's head like a whore, Ruin thrust his hips like a beast in rut. Used in her mouth, Iris teared up... and swallowed the semen that filled it. She stuck out her tongue to lick the remnants from her lips, then smiled brightly with a happy expression. Iris... was delighted right now.
"You too... Did it feel that good, oppa?"
"Sorry... Was I too rough?"
"Oh, not at all? Being used by you... was the best."
"Glad to hear it."
"So, um..."
"Yeah?"
"Can you... use me more intensely?"
Ah, Iris...?!
The fellatio was nothing.
Iris stripped naked herself and climbed onto the bed... spreading her legs, ready to take him in. Naturally, her pussy was soaking wet, twitching in anticipation of his cock. Cute yet incredibly seductive—her pussy. Seeing it confirmed, Sirius felt uncontrollable revulsion.
He should look away...
But he couldn't bring himself to.
He'd embraced women whenever lust built up... but this pussy was a first. Pure and innocent, yet desperately craving cock—so slutty. Sticky love juices dripping from the tight slit. Sirius stared. As her brother, he should close his eyes... but he couldn't.
Reason as family versus instinct as a man.
Wandering between them, Sirius sank to his knees.
But his gaze stayed fixed on his sister.
"Iris. You okay?"
"Yesss, I can't do full sex yet... but it's fine, hurry... come here, oppa."
"Wait a sec first... Come here?"
"Huh?"
"Under the light. Wanna see closer."
"O-Oppa... Okay..."
The arrogant doctor spread Iris's pussy. Her cute pussy... fully exposed. The hymen symbolizing purity and the lewd folds beyond the entrance. As Sirius imagined the thrill and berated himself, Dirk Ruin tasted his sister's pussy. His thick tongue lapped at it, drawing a slutty moan from Iris.
Sirius's crotch swelled.
"Haah, aaaang... Oppa..."
"Iris..."
"No, oppa... It's dirty, ungh..."
"Not dirty at all."
"Aaah, oppa..."
The problem was her calling "oppa" during those lines. It felt like she was calling for him, shattering Sirius's reason. His little sister, raised like a daughter since childhood, panting like that... calling for him. Sirius started deluding himself. His bulging crotch grew harder. But all he could do was...
Watch his sister being used.
"About ready...?"
"Yesss, here..."
"Your thighs are so soft every time."
"Unngh, yeah... Oppa too, haah... your cock's always so hot."
"Haha, here we go then."
"Yesss... Haah! Ungh... Haah, ungh... Oppa!"
The doctor's cock devouring his sister's soft thighs. Brushing past her pussy and rubbing her clit, making Iris buck her hips and call "oppa." Once, twice, three times... Each "oppa" made Sirius twitch too. But the one overlapping with Iris was Dirk Ruin.
"Oppa... Haah, oppaaa!"
It was no longer "treatment"—just pseudo-sex between sister and doctor.
Yet Sirius couldn't stop them.
Because of his throbbing, rock-hard cock.
In the end, he had to stay hidden until the finish... watching Iris climax soon after, and the doctor not stopping. Only after she came twice—no, three more times—did Dirk Ruin ejaculate. His precious little sister's body defiled with semen. And his pants were the same.
"Haah, Iris..."
"Oppa... Haah, I love you..."
Sometime later, Sirius plugged his ears against the words he didn't want to hear and left the room in an awkward position.
And Dirk Ruin stared right at him.
Saying this might be a bit much, but... seeing Siwoo suffer felt so damn refreshing. After fucking Iris, Sirius sobbed silently. The idiot clutched his erection, not knowing what to do... It felt like all my built-up stress melted away.
But Sirius, this is just the beginning.
I'm planning to impregnate her too.
So wait patiently.
Thanks to you always energizing me, Siwoo, I made plans for more NTR. A few days later, after fully reassuring Iris, I headed to the knight order with a relatively light heart. We'd done pseudo-sex until yesterday...
Today, it was time for the real thing.
