Side Story - Is Step-Sibling Incest Wrong? (1)
This side story takes place after Rina's public urination incident, focusing on Rena's tale. Even after receiving Rina's urine, Rena diligently roamed the estate to complete the remaining orders.
Extracting semen from the male Gano slaves wasn't all that difficult.
"How's it feel? You about to cum soon?"
"Y-Yeah... I think so, Rena sis. Could you maybe take the last bit in your mouth?"
"What a pain... Fine, I'll do it. Here goes!"
"Ah, so this is fellatio... Ugh!"
"Hah! *Cough, cough*! Hah... You could've at least given me a heads-up before blowing your load, right?"
"S-Sorry, Rena sis."
The freshly adult, hormone-raging boys went slack-jawed and eagerly handed over their semen the moment Rena flashed her naked body. But the female Gano slaves were the problem.
"Rena sis? Pee in front of a crowd? No way I can do that!"
"I'm about to get gang-raped as punishment... Can't you help me out just once?"
"That's your problem, sis. Anyway, I'm not doing it. You think I'm a seongnoye like you?"
"Even though it's an order from Young Master Ricardo?"
"I'm my master's slave, not Young Master Ricardo's. Ugh... Sis, help me out here!"
"Fine. Sorry for bothering you. I'll head out."
The female Gano slaves recoiled in disgust, flatly rejecting Rena's pleas. Scornful glares and icy sneers came as bonuses. Some even banded together to threaten her. Rena tried leveraging Ricardo's name for pressure, but the madman's authority—treated like an unwanted bastard child by the family—held no sway for long.
In the end, Rena couldn't collect a single drop of urine from any girl except Rina.
"Hah... This isn't easy. Looks like I'm in for it now."
Rena's heart had shattered and dulled long ago, but Ricardo's sadistic punishments—gang rapes or being treated like a living toilet—were still far from welcome.
"Guess I should look for Leon one last time."
Rena set off to find her one and only stepbrother. She pondered where he might be hiding. The last she'd seen of him, he'd been dazed, peeking at Rina's outdoor urination show.
"Then he must be there for sure... God, I hope not."
With a sigh-laced mutter, Rena headed toward the secluded thicket by the family forest. It was a remote spot even the foresters rarely visited.
"Hah... Rina...! Rina...!"
Rough breaths and Leon's voice pierced Rena's ears. She crept cautiously toward the sound.
As expected, Leon was there, leaning against a tree and jerking off.
"Rina... I love you... your tits..."
Leon furiously stroked his massive cock. Hah... Right on cue.
Rena let out a short, pitying sigh and pushed through the bushes toward him.
"Leon, jerking off again?"
"Gah! What the—Sis! Make some noise when you walk!"
"I didn't hide my footsteps. Your head's so full of Rina, you just didn't hear."
"Ugh... You heard all that? So embarrassing... But sis, you okay? I heard that psycho Ricardo's making you run around naked doing weird shit."
Leon gazed at his sister with worried eyes. He hated seeing his step-sis humiliated like this.
"I'm fine. Not my first rodeo. And watch your mouth, Leon. Young Master Ricardo might be a laughingstock in the estate, but he's still nobility."
"Still... Ricardo's a trash heap who gang-rapes you, parades you around like this, and piles on the humiliation!"
Leon vented his rage carefully, mindful not to hurt her feelings.
"Not wrong, but we're slaves. One flick from that trash noble, and our lives are over."
"Agh, got it, sis... So, you finished most of the orders?"
"...Yeah, you're the last one. Just need your semen, Leon."
Of course, it was a lie. Without the other girls' urine besides Rina's, punishment was inevitable.
"My semen? You want me to do it right here?"
"I'll jerk you off. Did it for the others too."
"...But we're siblings. Feels kinda off, right?"
"Don't get shy now. It's not our first time."
Leon flushed crimson at Rena's bluntness. A few days ago, right here, he'd been caught mid-jerk by her. Feeling sorry for her pathetic little brother, she'd offered her body. That day, Leon had lost his virginity.
"Th-That was... I was drunk off my ass, not in my right mind."
"We're slaves anyway. No better than dogs. Picture it—woof woof."
Rena mocked him flatly, mimicking a dog with a straight face.
"Even dogs fuck their moms without hesitation. Doing it with sis... a step-sis at that... is small potatoes."
"Ugh... Still feels wrong when I'm sober. Can't I just jerk off for you?"
"Why? Because of Rina? Leon, you're not even her boyfriend."
Rena shot him a sharp glance. Leon flailed his arms in panic.
"W-Well... True, but still..."
"Hah... As your big sis, advice: don't fall too hard for Rina. Better to give up early—for your own good."
Leon frowned back at her.
"Why? You gonna trash her like the others? Say she's got a shitty personality or is a slut? Rina's not like that. You got major help from her today too."
His sudden fervor made Rena nod along.
"I don't think Rina's bad. Her blunt guy-talk rubs people wrong, but deep down, she's a good kid. I know that."
"Th-Then why say no?"
"You know how it ends for guys who get tangled with Rina. Think about the Gano boys who confessed, or her friends with Luna."
"That's not Rina's fault—the master's pulling strings!"
"Maybe, but I still say she bears some blame. And without the butler stepping in, you'd be in deep shit already."
"......"
Leon had no comeback; it rang true. He fell silent.
"Plus, yeah, she helped me today, but Rina's dangerous at her core. She instinctively knows how to handle men."
"Even you say that? Got proof she's dangerous?"
"No proof—a woman's intuition? Point is, if she wanted, she'd toy with guys like playthings, who knows what she'd do."
"Rina would never!"
Leon shouted with conviction. Rena sighed deeply, worried.
"Think what you want. I'd talk till I'm blue, you won't listen. Anyway—want me to jerk you off or not?"
"Ugh... Feels like it'd prick my conscience..."
"Really? My pussy's spotless today—no one's touched it."
Rena casually spread her folds, showing him. Glossy pink flesh shimmered before his eyes. The raw sight made Leon's cock throb massively.
"Heh! Your body's honest, Leon."
His mind tangled at her teasing. Instinct screamed We're slaves—step-sis sex is fine, while reason whispered Mom's memory forbids it. But instinct always won. His youthful lust crushed faint morals.
"Ugh... Fine. Please, sis."
"But not like last time—no riding you. You thrust into me this time."
"You want me to...? Why?"
Rena pouted, cheeks puffing—a rare expression for her stoic face.
"Last time on top, your monster nearly pierced my womb. Killed me. Your dick's basically a weapon."
"Mine's that big...? Okay, I'll be gentle."
Leon nodded. Rena smiled faintly, leaning her head on his shoulder.
"Good. Special occasion—your coming-of-age too. Ask for anything reasonable."
"Anything?"
"Depends what. But yeah, speak freely."
Leon hesitated, then ventured:
"Uh... Could you do piercings?"
"...Piercings?"
"Yeah. Always wanted to tug on one myself."
"......"
Rena stared blankly at her lone brother.
"S-Sorry if that's weird. Forget I said it, sis."
"Hah... Who'd you get this pervy from? Fine, I'll do it."
"Really?"
"Yes! But don't pull this on Rina or other girls later—or a slap won't cut it."
"Got it. Thanks, sis!"
Rena pulled hidden piercings from behind her choker and fitted them to her nipples. Cold metal pierced sensitive flesh, sending dizzying thrills.
"Ngh..."
A rare lewd moan escaped her.
Sheesh, skipped 'em to dodge Ricardo... Never thought it'd be for my brother.
She chuckled wryly, expertly adding her clit piercing.
"Eek!"
Leon gripped his cock hard at the sight.
"Hah... Like it?"
Rena posed seductively—hands behind head, legs parted.
"Sis, you're so hot... Total perv."
"Who's the perv? You're the one who asked!"
She flushed, snapping.
"S-Sorry, sis."
"Whatever. Show me what you got."
"Huh? How?"
"Coming-of-age today. Bet the senior guys drilled theory into you. Use my body as practice—go wild."
"Practice?"
Rena lay on the grass before him, arms up, legs spread—utterly vulnerable and inviting.
"What're you waiting for? Not ramming in dry from the start, right? Ravish me however."
The dizzying view shattered Leon's reason. Incest guilt vanished. Raw primal lust ruled his brain.
Leon approached with beastly eyes. He towered over her by a head; his bulk even more overwhelming. Staring down, Rena swallowed nervously.
Damn, he looks scary like this... Hope he doesn't go too rough. Gotta keep big-sis dignity.
She quashed her fear.
"G-Get ready, sis. Seniors taught me tons."
"Hehe, cute. I'll correct any mistakes. Go on."
Leon’s cock swelled, dripping precum. Rena’s pussy glistened, soaked. Four dark eyes burned with thick lust. Blood didn’t lie—they were unmistakably siblings.
