Side Story: Is Incest Between Step-Siblings Wrong? (2)
Leon let out a ragged breath as he tightly embraced Rena from above. Their scorching body heat mingled intimately.
"You smell so good, Sis."
"Leon, you're heavy... Could you get up just a bit?"
"S-sorry, Sis."
Leon sprang up and sat down in front of the reclining Rena.
"O-okay then, let's start now, Sis."
Leon grabbed her nipple piercing from below and yanked it down hard.
"Ahh♡! Leon, that hurts! What if you pull so suddenly and rough like that?!"
"D-did it hurt a lot? Sorry, Sis."
"Hah...♡ A woman's breasts are sensitive, you know. You can't just yank them roughly like that."
Rena puffed out her cheeks, glaring at the clumsy Leon.
"And starting by tugging on the nipples right away is way too hasty, Leon."
"I-is that so? The seniors told me this is how you take control from the start."
"Treating someone that roughly is something only an owner does to a sex slave. Sure, I'm a sex slave, but I'm not your sex slave!"
It must have hurt quite a bit, because Rena's pout was plain as day.
The flustered Leon waved his arms in the air, making excuses.
"I'm really sorry, Sis. Some senior told me this is how he seizes control with the breeding slaves..."
Rena's expression turned ice-cold in an instant at his words.
Breeding slaves. House slaves dedicated to relieving the male house slaves' sexual urges. They were also used as tools to bear children and increase the household's slave numbers. Living in a separate place called the Mercy Hall, they had to offer their bodies to the male house slaves every night. As a result, even among house slaves, they ranked lower than sex slaves and were treated no better than whores.
"Filter out that kind of low-class advice, Leon. And even if you go to the Mercy Hall later, don't treat the breeding slave sisters too roughly."
"Of course not. Our mom was a breeding slave too. How could I..."
Leon and Rena's birth mother had been a breeding slave as well. She had passed away during childbirth when Rena was three and Leon just one, along with the fetus. So the siblings had no real memories of their mother.
The heated mood chilled into solemn silence at the mention of their mother.
"I'm glad you say that. I was worried you'd treat breeding slave women like whores, just like the other guys. I'll end up as one someday once I get older."
"Why would you become a breeding slave, Sis? I'd never let that happen!"
Breeding duties usually fell to aging sex slaves or female house slaves whose bodies were too worn to work properly. Rena, as a sex slave, had a high chance of falling into that role in the near future. But Leon could never bear to see his sister worked to death like their mother.
"Hehe, thanks for saying that, even if it's just words. I ruined the good mood for nothing. Sorry, Leon."
Rena spread her arms again, gazing at him with seductive eyes.
"Let's get back to it."
"Huh? Oh, okay, Sis. So what do we do next?"
"A kiss, maybe? That's the basics between lovers."
"W-well, we're not really lovers, are we? We're still siblings..."
Rena's face flushed beet red in an instant.
"Th-that's not what I meant! I just meant pretend I'm your lover and practice!"
"O-oh, got it. Then... maybe I'll pretend you're Rina?"
Rena's expression stiffened slightly at his words.
Leon, you idiot.
Rena let out a short sigh inwardly and reluctantly nodded.
"Haa... Fine, do whatever you want, Leon."
"Got it, Sis. Here goes."
Leon gently cupped Rena's cheek. Their faces drew slowly closer. Rena wrapped her arms around his sturdy back.
"Rina... Rina."
It wasn't exactly pleasant to be held and called another woman's name, but the strange sense of liberation this situation brought had Rena utterly intoxicated.
Not that crazy Young Master Ricardo, not the stinking other house slaves... A kiss with Leon. I'm so happy.
Rena quietly closed her eyes. Leon's lips clumsily pressed against hers. His mouth opened with a rough breath, and his thick tongue pushed into her mouth.
Compared to Ricardo or the other men's skilled techniques, it was definitely amateurish. But Leon's efforts to please her made Rena find it all the more endearing.
Their sticky saliva mixed, producing lewd, wet sounds. When Rena cracked her eyes open, the same black eyes as hers sparkled right in front of her.
Their flushed faces parted, a thin thread of saliva stretching long in the air between them.
Sweet... I want to do it again.
Leon broke the ecstatic silence first.
"Uh... Rina—no, Sis. Did I do good?"
Rena nodded with an expression laced with female instinct.
"Hah...♡ Yeah, it was the best. But you know, it's kinda unfair now that I think about it."
"Huh? Did I mess up?"
"I'm not wearing a stitch, but you're still fully dressed. Not fair. It makes me feel less like your lover and more like your slave."
"S-sorry, Sis. I'll strip right now."
"Wait. Let your big sis undress you."
Rena sat up and began peeling off Leon's clothes one by one. Her expert technique used only her lips and teeth, barely her hands. For a moment, Leon fantasized that he was Rena's master. He imagined his step-sister groveling at his feet, begging "Master" in a lewd plea.
"Leon! I've got you naked, and what's with that look? You were imagining something pervy again, weren't you?"
"Huh? N-no! I absolutely wasn't."
"Whatever. Let's keep going then. I'm getting cold—hug me quick and caress me everywhere."
It was early summer, the month of June, but Rena craved warmth more than ever right now.
"O-okay."
Leon enveloped her in his large hands, stroking her body tenderly. Her slender arms, firm thighs, and ripe, elastic ass. Unlike before, he touched her gently, without causing pain.
How long has it been since I felt such gentle caresses? Feels so good... This body heat is so warm.
Rena admired her brother's careful consideration, but now she was starting to feel a teasing itch.
Her pussy was already soaked, dripping slick fluids.
"Hah...♡ Leon, you can be a little rougher now."
"R-really? Okay, I'll try."
Leon gripped her breast firmly with one hand. It filled his large palm perfectly.
"Ahh...! Good, Leon. Squeeze harder. Pinch the nipple part stronger if you can."
"Like this?"
Leon squeezed her breast as instructed. The piercing made her hypersensitive nipple send intense jolts straight to her brain.
"Hng...♡! Yes... Leon, how do my tits feel?"
"G-good... N-no, I mean, they feel amazing, Sis."
"...Leon, you were just thinking of Rina's tits, weren't you?"
Rena pursed her lips, interrogating him. Leon panicked and averted his eyes, hitting the nail on the head.
Rena's breasts were plenty great, but they paled against the overwhelming volume he'd accidentally brushed against from Rina that morning.
"Rina's the one with freakishly huge tits—mine aren't small!"
"O-okay, Sis. Sorry."
"No, really! Mine are totally average, and girls like Rina are the weird ones!"
In truth, among the Orpen household's sex slaves, Rena's breasts were on the smaller side. She never showed it outwardly, but their size was a real complex for her.
"Really! You're such an idiot, Leon—no sense at all. Now I'm mad."
Rena huffed and flopped face-down on the floor, as if hiding her chest.
"S-Sis, my bad."
"Whatever, go fondle Rina's massive tits later."
"No, I didn't say your tits are small."
"Ugh...! They're not small! You have zero delicacy, Leon."
Leon was starting to get irritated by his sister heating things up only to douse them with cold water.
"Fine, I learned what to do in situations like this, Sis."
"Huh? W-wait, what are you doing, Leon?!"
Leon roughly grabbed her ass and thrust his massive cock inside her in one go.
"Ahh...♡ What if you shove it in so suddenly like that! Haaang...♡ Stop, pull out right now!"
"Just hold on a sec, Sis."
Leon's cock filled her depths completely in a single stroke.
So deep... Something this huge is just unfair.
Rena shivered at the heavy pressure on her vaginal walls and cervix. The tip pressed relentlessly against her womb entrance.
"It's all in. How's it feel, Sis?"
"Hah...♡ What the hell are you doing, Leon?!"
"One senior said when a girl's mad, just shove it in and she'll be helpless... You don't like it?"
Leon asked in a worried tone.
"Hah♡, it's not that I hate it... You just scared me. Never do this to other girls."
"I-is that right? Sorry, should I pull out?"
"Hah...♡ No, don't pull out... Since it's in, move slowly."
"Got it, Sis!"
"Haaang♡ Slowly! Please, slowly!"
Despite Rena's desperate plea, the aroused Leon had already lost control, pistoning his hips fast.
Squelch—squelch—squelch.
"Haaang♡ Ahh♡ Too deep! Hah...♡ Please, gentler...!"
Her womb entrance squealed in protest. The pain of being impaled like a stake mixed with the pleasure of being stuffed full, slamming her brain.
Leon's heavy balls slapped wildly against her mound.
Ah... Leon's balls are hitting my clit... It's so sensitive from the piercing... Feels too good.
Their breaths grew rougher and hotter.
"Ngh... Sis, you okay now?"
"Haaang♡! Yeah, I can breathe now... Hah...♡ Deeper, fuck me deeper. Ahh...♡ Make my insides all yours!"
"O-okay, Sis, lemme change position. This might be better."
"Hah...♡? W-wait!"
Leon lifted Rena's body while still buried inside her, then started thrusting again while holding her in midair.
Squelch—squelch.
"Haaah♡ S-scary, Leon! This position goes way too deep! Haaang♡! It feels like I'm your onahole."
"Ngh... How's it feel, Sis? Aren't I strong?"
"Hah...♡ Please, go slower... And don't you dare drop me. If you do, I might really get pierced through!"
"Ngh... Beg me politely, Sis. Then I'll go easy."
Leon shook her body up and down even more mischievously.
"Hng♡! Ahh...♡ Polite? N-no way! Haaang...♡ I'm your big sis, after all!"
"Not gonna? Maybe I'll drop you then?"
"Hng♡! Sorry... N-no, forgive me! This perverted worthless sis was arrogant to her little brother—I'm truly sorry!"
"Uh... Th-that's more than I asked for."
Stunned by how humiliatingly she begged, Leon's arms slackened. In that instant, Rena's body dropped down.
Gravity amplified the thrust, mercilessly crushing her womb.
"Hk♡! D-don't drop me like that—m-my womb's wrecked! Haaaaang♡♡♡!!!"
Rena squirted lewd fluids in an explosive orgasm.
"S-Sis! You okay?!"
The terrified Leon yanked out and laid her on the floor.
"Sis, come back to us! A-are you okay? Sniff... Sorry, I won't do it again."
"N-no... Do it..."
"What, Sis? I can't hear you."
Tears streamed down Rena's unfocused face. But she wore the happiest smile ever.
"Hah...♡ N-next time... do it just like this... It was the best, my little brother's cock."
