My Little Sister Is the Best F*p Material - Volume 8 Chapter 08: Impregnating the Cheeky Beauty

Volume 8 Chapter 08: Impregnating the Cheeky Beauty

The petals were breathing—or so the metaphor for female genitalia goes. The lascivious folds before me opened and closed with heavy breaths, blooming as if to entice my erect cock.

Two sets of them. My real sister and my best friend, a beautiful girl, their perverse, dripping slits stacked vertically, eagerly awaiting my insertion.

“Sotomichi-kun… hurry…”

Yamamoto-san, breathing heavily, shamelessly spread her legs, craving my raw cock. A hole consumed by sex. Her true nature, glimpsed during our dates, was now fully exposed.

“One cum, one round.”

I hooked my arms under Yamamoto-san’s knees, signaling missionary insertion. Despite unloading massive amounts of cum already, my cock pulsed eagerly to ravage another girl.

“Onii-chan, don’t keep me waiting too long either.”

Above this lewd beauty, my hopeless siscon sister formed a vulgar meat sandwich with her ample breasts. Her ass toward me, she dripped arousal shamelessly, awaiting her brother’s creampie. My cock, unusually veined and throbbing, stood irritated.

“No need to tell me…!”

Zubuzubu—my cock ached as it entered Yamamoto-san’s vagina. Already engorged, it forced blood to make itself even fiercer. Animal instinct surged, my heart pounding uncontrollably, as I pushed through her slick walls, driving my raw cock deep.

“Nn, aah… aaahh!!”

Yamamoto-san moaned at penetration. Feeling her tight vagina for the first time, I forced my cock in. The raw, forceful sensation seemed to thrill her too. As sex began, she writhed, unable to hold back moans of pleasure.

“Haa… guh… Yamamoto-san’s pussy… sucking me in…!!”

Each thrust made guppo guppo sounds, like a vacuum blowjob. Despite licking and sucking my cock earlier, this lewd girl still wasn’t satisfied.

“Haa, haa… what do I do… nn… doing it raw… ah, nnaa… no… feels so good…!!”

Despite resisting raw sex, or perhaps because of it, she was too aroused to retain any rationality. Knowing a creampie was coming, she seemed to suck cum from my balls forcefully.

“Damn… this… haa, aah… guh…!”

Feeling her hole’s pleasure, a new emotion stirred in me. Beyond mere pleasure, this raw sex felt like mating. My male instinct, once limited to erection and ejaculation, now craved more.

I wanted to impregnate them. These cheeky beauties, pill or not, I wanted to fertilize.

My sexual instinct had fully shifted to reproduction. Their erotic bodies demanded it. Consequences be damned—my cock surged for breeding. Pulling Yamamoto-san’s hips, thrusting with every muscle, I urged her ovulation.

“Hia, ah, ah, noo…!! Hyu, hyugii… guh… aaah… haa, nnaa… no, noo… I’ll go crazy…!!”

As Yamamoto-san climaxed wildly, I kept thrusting. Miyu, watching, hurriedly cupped her cheeks.

“Not yet! You can’t cum so pathetically on the first round. Onii-chan’ll get you pregnant!”

I was to creampie Yamamoto-san five times. In this state, she might actually conceive. So be it. After her, Miyu’s next.

“But… but…!!”

Yamamoto-san was cumming beyond her control. My own urge peaked, the first creampie nearing.

“I’m cumming… inside you…!”

Like with Miyu, I pressed my cock to her cervix and ejaculated.

“Hiaa… ihigu… Sotomichi-kun’s creampie… aah… I’m… cumming…!!”

She climaxed with my release, my cock pulsing doku doku, shooting semen against her womb’s entrance.

“Haa… haa… creampie… feels so good…”

Yamamoto-san reveled in her first creampie’s pleasure. Miyu, unable to hold back, wiggled her ass, urging insertion.

“Onii-chan, Onii-chan.”

Begged by Miyu, still in breeding mode, I thrust into her vagina to maintain my impregnation drive.

“Aaaah…!! Onii-chan’s… harder… bigger…!!”

Miyu’s tighter hole gripped me as I pistoned slowly, wiping my cum-soaked cock on her folds. Using Yamamoto-san’s breasts as a pillow, Miyu lay nearly prone as I covered her, teasing her nipples and thrusting piercingly.

“Hia, ah, no… I’m cumming, cumming…!!”

On her second raw sex, Miyu climaxed faster than Yamamoto-san. After a few thrusts, her vagina spasmed.

“Aah, aah… aaah… hia, hyugoiroo…!”

Unable to endure my breeding cock for seconds, in this lewd space, it hardly mattered.

Pounding Miyu from behind, I wanted to impregnate her even more than Yamamoto-san. The urge to cum inside her womb was overwhelming, but I couldn’t voice it—Miyu would obey instantly. I held back.

“Haa… Miyu-chan… you look so happy with Sotomichi-kun…”

Yamamoto-san, breathing steadied, gazed dreamily at Miyu being taken from behind. Once flustered by others’ sex, she’d adapted to our threesome.

“Ah, ah, ah, aah… no, feels… good…!”

“Keep going, Miyu-chan. Your beloved Onii-chan’ll cum soon.”

“Haa, fa, aah… semen… haa… Onii-chan’s… ugh, gu, ah… haa… cum, I want your cum…!”

Egged on by Yamamoto-san, Miyu moaned sweetly, losing decorum. My pulsing cock readied its load.

“Miyu… Miyu… I’m cumming…!!”

“Aa, aaaah… Onii-chan… come, come inside…!!”

Dopyu, dopyu, dobyubyu, dobyu—!!

I felt thick semen flow through my urethra. Despite claiming just to cum, both Yamamoto-san’s and Miyu’s creampies were breeding-level loads.

“Haa, haa, haa…”

Relentless creampie sex, using nearly all my stored semen, not sparing any. My stamina waned, but—

“…Guh… next, round two…!”

Willpower kept me erect. Thanks to summer’s excessive ejaculations with Miyu, I could force erections like flexing a muscle.

My heart pounded like it might break, sensing I’d die if I hit ten rounds, yet I thrust my raw cock into Yamamoto-san’s vagina.

“Aaah… Sotomichi-kun… so big… still… huge…!”

Once erect and inserted, her molten hole enveloped me, keeping me hard.

“Fuu, aah… Yamamoto-san’s pussy… so hot…!!”

My hypersensitive skin felt her searing juices. The thin condom had felt like a thick wall; raw sex revealed her vagina’s texture and softness vividly.

“Aah, ah, ahh…! Sotomichi-kun… haa, amazing, aah, nn, no, ah, aaah…!!”

Thrusting made her writhe in climax. That male pride fueled my lust.

“Fua, ah… Onii-chan, going so hard… cumming too much in Kanade-san…”

Miyu, regaining awareness, dripping cum, chided our sex. Despite post-ejaculation, my breeding intent made my loads excessive. My empty balls, rocked by thrusts, recognized Miyu as the prime target, relentlessly producing semen. My body was molded for breeding these sex-crazed beauties.

“Ugh, aah, haa…! This is nothing… I’ll make you cum till I die…!!”

Having cum once, I gained some leeway before ejaculating again, but in contrast, I relentlessly thrust my rigid cock into their increasingly sensitive vaginas, drawing pained moans with unending stimulation.

Ten consecutive creampie sessions was a ridiculous demand, but if I could make them both pass out from orgasms, it’d be over. If Yamamoto-san couldn’t continue, it wouldn’t be my fault. So, I poured all my energy into her vagina.

“Aah, ah! Hiaa, aah… Sotomichi-kun… so intense…!!”

“Ugh… haa, aah… not yet… more… cum…!!”

No gentleness—just raw thrusting. Yet, Yamamoto-san’s thick vaginal walls absorbed every impact, turning it into pleasure. My forceful pounding seemed to resonate perfectly with her.

“Haa, haa… Sotomichi-kun… this is… amazing… aaah, fua, ah… hia, ah, ah, aah… feels so good…!!”

Her wetness, looseness—her vagina, already at its peak, clung to my cock as if memorizing its shape. Facing such a perfect hole, I couldn’t thrust mindlessly, and my third ejaculation loomed.

“Aaah… guu… kaa, haa…!!”

Wrapped in her hot juices, the urge to cum overwhelmed me quickly. Like a blissful leak, I reached orgasm inside her.

“Sotomichi-kun… Sotomichi-kun…!!”

“Aaah… cumming, cumming…!!”

My supposedly depleted semen squeezed out, steadily reducing my sperm count, gushing dopu dopu into her vagina.

“Fuaa… hyugoi… Sotomichi-kun’s… semen… I feel it pouring in…”

“Haa, haa, ugh… guh…”

Three consecutive creampies drained my semen and strength, yet I couldn’t stop. Stopping now would mean never rising again.

“Miyu… here I go… cumming inside again…!”

“Onii-chan, still hard… shu, shugo… ah, aaah…! Kihya… aah, nna… hia, aaah…!!”

Miyu came the moment I entered, surrendering to pleasure. Men have orgasm limits, but this sister came so easily—it was infuriating.

The two beauties who’d called themselves my cum tools now toyed with me as a cock plaything. My cock, enraged by this, stayed taut to compensate for waning arousal.

“Nna, ah, Onii… chan…!! So rough… ah, fuaa… no… e…!!”

Her vagina ravaged, Miyu protested verbally but smiled. Below, Yamamoto-san, exhausted from her second creampie, trembled with arousal watching our sibling sex.

“Miyu-chan, Sotomichi-kun… so lewd… haa… just watching Miyu-chan get fucked… I’m…!!”

Making Miyu cum forcefully, she twitched with orgasmic spasms despite limp limbs, and Yamamoto-san, influenced, jolted as if penetrated in sync with my thrusts.

Their nipples connected, and each time I lifted Miyu, the friction made them moan and kiss greedily, sharing lust.

“Haa… haa, damn… satisfying two erotic girls alone…!!”

Anger surged, but my cock was at the mercy of Miyu’s greedy vagina, refusing to stop despite countless climaxes. Normal girls would’ve collapsed by now, but these two crawled back like zombies no matter how intense the orgasms.

“Onii-hyan… Onii-hyan’s… sex… shuki… ah, agu… fuaa, nna, aah…!”

“Damn… Miyu… aah… gu, ugh… Miyu…!!”

I couldn’t hold back. I’d cum again. I thought I could last after insertion, but their bodies pushed me beyond imagination. A woman’s body craving cum felt this good?

“Enough… cumming, Miyu… inside… cumming…!!”

“Nna, ah, aaah!! Onii-hyan!! Onii… hya… anngu, aah…!!”

Dokun, dokun, dokun—thick semen surged, overfilling Miyu’s already cum-soaked vagina with white fluid.

“Nn, nnn… Miyu-chan’s vagina… twitching… ah, fua… I feel it too…!!”

Yamamoto-san jolted in sync, both climaxing and collapsing limply.

“Ah, ah… Onii-chan’s… semen… in my womb again…”

Miyu, happily murmuring, kept cumming, feeling my sperm. Her tough face loved my cum most—truly hopeless.

“Haa… ahh… next… Yamamoto-san again…”

Pulling out of Miyu, I aimed for Yamamoto-san’s spread, gaping hole, but—

“Huh… where’s the entrance…?”

My cock was big but soft, lacking hardness. Despite trying the same way, insertion was impossible.

“Huh… ah… nn… Sotomichi-kun’s… melting at the entrance…”

Yamamoto-san smiled teasingly, but this was life-or-death for me. Only four sessions—two each—with six more to go. Despair.

“Only… halfway…!”

I tried stroking my slick cock, but it felt like rubbing jelly—numb. My cock’s sensation was dead.

“No way… gotta get hard…”

The more I panicked, the softer it got. Miyu, pitying me, reached between their slits, where their clits rubbed, spreading her fingers to invite my cock.

“Onii-chan, put it here.”

She meant my half-erect cock between their clits. My brain, fried by their perversion, couldn’t process, but my duty as Miyu’s brother drove me to comply.

“We’ll make Sotomichi-kun’s cock lively again.”

Yamamoto-san’s cheerful voice rang out. Her boundless stamina and lust made our four rounds mere foreplay. I was on the brink of death, yet these girls showed no mercy in making me cum.

“Look, feeling good won’t get me hard anymore…”

My balls were empty, corpora cavernosa exhausted, supporting muscles spent. The room’s musky sweat and semen stench would trigger sage mode, knocking me out completely.

Resigned, I inserted my barely erect cock between their clits, legs spread frog-like.

“Fuu… both so slick… feels good…”

Their mixed fluids acted as lube, a pleasure zone just from insertion. Still, it wasn’t enough to harden me.

They knew, giggling at my soft cock, enjoying it despite being sandwiched by their slits.

“First time Onii-chan’s so useless…”

“We really drained him.”

I’d abstained last night per Miyu’s orders, but today, I’d cum once each from their blowjobs and three times raw in Miyu. Thirteen in a day? They were insane to demand it.

“Nn… ah… sandwiching it… fa… nna… different from thigh sex…”

Miyu rocked her hips kui kui, using my cock for clitoral pleasure. Her pathetic floor-humping motion reignited my arousal.

“Ah… Miyu-chan, pressing so hard… nn, ah… my clit’s getting pushed… haa, ah…”

Matching Miyu’s rhythm, Yamamoto-san writhed pleasurably, moving her hips oppositely to keep up, as Miyu’s obsession with my cock spurred her.

“Aah… Kanade-san, no… clit stimulation… ah, ah… too strong…”

“Not fair, Miyu-chan enjoying it alone… haa, aah… feels good…”

Miyu’s thrusts made Yamamoto-san feel it; Yamamoto-san’s clit pressure made Miyu moan. Their mutual motions heightened their arousal, using my cock but ignoring me, lost in their breast-fondling sex.

“An, ah, ah… Miyu-chan… feels good…!”

“Kanade-san… fua, intense… no, ah, already…!”

“Miyu-chan, you’re so quick… I’ll make you cum!”

“Ah, ah… hia, ah… no, no… aaah!”

Yamamoto-san thrust fiercely, making Miyu cum, their dripping juices echoing nucho nucho.

My cock, used between them, grew irritated, veins bulging, amplifying their clitoral stimulation like studs.

“An, ah, Onii-chan’s… hard… hia, ah… again, higu, I’m… gu…!”

“Sotomichi-kun’s… getting big again…! Haa… amazing… ah, aah… wanna feel it inside…!”

Their lustful moans hardened my cock. Instead of inserting into Yamamoto-san, I leaned forward, keeping it between their slits.

“If it’s that good… cum from your clits…!!”

I hugged them tightly, pressing their crotches together, forcing my hard cock against their clits.

“Haa, haa… both of you, cum…!!”

Using recovered strength, I pistoned fiercely, grinding their sensitive buds with my glans.

“Agaa, haa, higu… ah, ah…!! Onii-hya, no… feels, ah, nnaaa…!!”

“I’m… cumming, cumming…!! Aaah… so hard, hyugoi…!!”

They moaned higher, crying. Unaccustomed to clitoral orgasms after vaginal focus, I thought they’d collapse. Wrong.

“Onii-chan… more, more…!! Want it, love it…!!”

“Hiaa, aah, nnaa…!! Sotomichi-kun… feels so good…!!”

The more I rubbed their clits, the more they craved. With lewd, pleasure-obsessed eyes, they stared, needing nothing else.

Even this failed. I forgot Miyu, my lewd sister, loved masturbation and was used to clitoral stimulation.

“Guh, aah, no, ah, ah, no… ugh…!!”

My cock, slick with their fluids, was visible from the side, tormented by these erotic girls. Despite cumming repeatedly, they mocked my desperate thrusts with smug faces.

“Aah… kuh, ah, no… I’m cumming… cumming…!!”

Their lascivious magic flashed “defeat” in my mind. My cock signaled semen release, unstoppable.

“Yamamoto-san’s vagina… cumming inside…!!”

Just before ejaculating between their stomachs, I pulled out and thrust into her vagina. In that split second, I pounded her hole with full force.

“Nnaa, it’s here… haa, haa… Sotomichi-kun’s… nna… just for cumming… ah, aaah…!!”

Used like a cum dump, Yamamoto-san’s rough treatment spiked her arousal, climaxing from one thrust. Her pulsing walls drew my dopyu, byu, byururu—a massive load, completing my third breeding.

“Haa… AAH—?!”

Then, pain shot through my forcibly erect cock, like it cracked. My muscles stiffened, my pounding heart stilled by a piercing shock.

“Ah… ahh…”

I thought I died.

Strength drained, I collapsed onto the bed.

I died from too much sex. Repeatedly ejaculating and thrusting with these erotic girls cost me this. No regrets—I died embracing such beauties. No way I’d—

“Sotomichi-kun…? You okay…?”

Yamamoto-san’s voice reached my fading consciousness, its tremor alerting Miyu, who turned to me, finally realizing I’d hit my limit.

Miyu struggled to sit up, shifting from her ass-out position to crawl toward me.

“Onii-chan, you can’t die from sex.”

Her unexpectedly stern encouragement snapped me back to reality. I couldn’t die here—not yet.

This was just a step. Reconciling with Yamamoto-san, then indulging in endless love with Miyu.

“Ugh… ah… aah…”

My groan-like reply seemed to reassure them, and they resumed giggling, ignoring me.

I was done. Impossible. Ten consecutive creampies was never humanly possible. I’d leave the rest to Miyu. I’d done enough, right?

“Onii-chan, you said just cumming, but it’s too much.”

“Even scooping it out, there’s still so much… wow, it’s warm.”

“You even gave that much to Kanade-san.”

They scooped cum from their vaginas, spreading it on Yamamoto-san’s stomach, chatting. No way my balls held that much, but I stopped questioning the mechanics.

“The sheets are a mess.”

“Might need to replace them…”

Sweat, semen, and juices stained the sheets, proof of the night’s intensity. The high AC setting left the air thick with lascivious fluid scents, making them erotic.

“Miyu-chan, you don’t mind licking this stuff?”

Yamamoto-san pointed to the cum on her stomach. Miyu would eagerly lick my semen, but this was mixed with their juices.

“Not mind… is a bit misleading. I don’t mind my own, and with someone compatible, it’s not bad.”

“Compatible, like me?”

“Yeah. As I mentioned before… I don’t know the exact conditions, but biologically similar people are easier to accept.”

Miyu loved herself, me, and Yamamoto-san, who resembled her, making her highly compatible. Maybe that’s why Miyu favored her—instinctual preference.

“Huh… Actually, I’m kinda curious now.”

Yamamoto-san’s words made Miyu think she meant the cum, but then she realized it was something unexpected.

“Huh, nn? You mean—”

“Hehe, well, I figure I won’t get to do stuff with a girl again. Life experience, you know?”

“There are experiences you don’t need.”

They talked, Miyu licking my semen to demonstrate, then their conversation turned serious.

“Protein, if left long, smells bad. Better clean it up, right?”

“We’ll shower…!”

“Come on, it’s a rare chance, please!”

“Ugh… umm… but that’s…”

I half-listened, my consciousness hazy, missing their meaning. That Yamamoto-san, once flustered by our sex, would suggest girl-on-girl action was unthinkable.

“Not in front of Onii-chan…”

“No better time. Turn your butt this way. I’ll make it feel good. My skills beat Sotomichi-kun’s.”

“That’s what worries me… wait, hey…!”

Miyu resisted, but couldn’t overpower Yamamoto-san. Still lying on the bed, Yamamoto-san lifted Miyu’s legs, forcing her crotch over her face.

Miyu’s face was at Yamamoto-san’s crotch, her own buried in Yamamoto-san’s. Undeniably, it was a sixty-nine.

“What the…!! A, GAH—!!”

I jolted at the realization, but exhausted beyond limits, I couldn’t move.

“Ah… aah… no…! Kanade-san… there… ah, nnaa…!”

Miyu moaned as her pussy was licked. Unlike during sex, her breathing had room, letting out unfamiliar moans. Exposing her secret place to Yamamoto-san, her creampied vagina was cleaned by her tongue.

“Nn… chuu… haa… hero… chururu… haa… Miyu-chan’s here, so lewd… haamu… juru, herojujuju…”

“Nnaa! Hia, no, noo! Stop, stop… ah… nnn… NN…!!”

“Miyu-chan, don’t just enjoy, lick mine too.”

Yamamoto-san lapped at Miyu’s clit and lips, savoring her first female touch. Brain-fried from my creampie or already broken, Miyu, manipulated, extended her tongue to Yamamoto-san’s slit.

“Haan aaah… Miyu-chan’s so good… ah, there… good…!!”

Two beauties, needing no man, pleasured each other’s sensitive spots. Their fair, plump bodies intertwined, breasts swaying, long black hair framing red tongues licking each other’s secrets.

I was cruelly erect. Watching my lover do something forbidden, I pathetically couldn’t stop my cock from hardening.

These girls, meant to focus on sex with me, ignored my erection—ride me if I can’t move!—and indulged in new thrills.

They were more compatible than I’d imagined. Infuriatingly so.

“Nn, muchu, ah… making me do this… no mercy now.”

“Ah, ah, there… feels good… hyugo… this… nnaa… first time…!!”

Miyu took the lead. Knowing how to keep a desensitized body sensitive, she varied her licking and fingering to keep Yamamoto-san on edge.

“An, aah… no… too good… so different from Sotomichi-kun…”

“Of course, who’re you comparing me to, geez.”

“Hehe, sorry, sorry.”

Realizing she couldn’t outdo Miyu, Yamamoto-san ended their play, sat up satisfied, hugged Miyu, and collapsed onto the bed.

“We did it.”

“Hope you don’t regret it later.”

Calming down, Yamamoto-san, the stamina monster, was fine, but Miyu looked exhausted. Her small body had endured so much.

I was left out. Fine, I was used to it. With no sex left in me, I had no role. Just furniture in this room.

“Hey, Miyu-chan.”

In the quieted room, Yamamoto-san brushed back Miyu’s sweat-soaked bangs.

“Why do you love Sotomichi-kun so much?”

And so began a girls’ talk.

“I told you before, right?”

They’d shared everything. Asking now seemed pointless.

“Back then, there were… complications. You didn’t lie, but I think you held back.”

Yamamoto-san guessed Miyu had chosen her words carefully for their reconciliation. Not quite right, but close. Miyu thought for a moment.

“It’s not so different from you, Kanade-san. I love the comfort of being with him. But… why that’s enough to love him might differ.”

Miyu spoke her heart, knowing I was still conscious, perhaps saying it for me.

“To love someone, you need to be happy with yourself first. Being able to live alone, but wanting to be with someone because they make you happier… that’s the right way to be lovers. But…”

Miyu spoke calmly, her tone steady.

“I can only love someone who makes me happier by being together. That’s the only kind of love I can do. So, it has to be someone like Onii-chan, who I’m certain will love me forever. I can’t take the step to date otherwise.”

This wasn’t about her physical condition but Miyu’s core as a person—a topic I’d never heard her discuss. It surprised me and filled me with quiet joy.

“The comfort I seek from Onii-chan is like that. With my condition and all, it’s convenient, but… I’m pretty serious… about loving Onii-chan…”

She ended shyly, and I nearly died from how adorable she was.

“You two really are a perfect couple,” Yamamoto-san said, stroking Miyu’s head before hugging her soft curves tightly.

“Thank you for going this far for me.”

Looking back, it might’ve seemed like cruel acts in isolation. But now, settled, Yamamoto-san could only feel gratitude. Her sincerity was unmistakable.

Hearing their voices, my consciousness faded into sleepiness. Everything was resolved, I thought with relief, proud of fulfilling my role. The reconciliation plan with Yamamoto-san concluded successfully.

Or so I genuinely believed at the time—

I fell into a deep, muddy sleep, yet woke at dawn as sunlight crept into the room. I was in the center of the bed, flanked by two busty beauties sleeping with my arms nestled in their breasts. Their long, dark hair sprawled messily across the sheets.

Their eyelids, occasionally twitching as if dreaming, fluttered with long lashes. Lips that had devoured my cock were plump and rosy. Even Miyu’s usually pale skin glowed with healthy moisture, like Yamamoto-san’s. Their sleeping faces were stunning, and glancing down, their pristine nipples belied our sex-filled days.

I wanted to savor this luxurious scene, but sadly, a pressing urge to pee threatened to ruin the sheets and mattress. Reluctantly, I freed my arms from their breasts, carefully sat up to avoid waking them, and headed to the bathroom.

My body ached, but surprisingly, it wasn’t immobile like before. Perhaps hardened by repeated sex with them, it felt light as I walked.

After relieving myself and washing my hands at the sink, my face looked anemic from over-ejaculation, but my muscles had a lean, athletic build.

“Impressive…”

Was it the brotherly instinct Yamamoto-san mentioned, or was my base physique, as Miyu’s brother, just gifted? I seemed to grow stronger the more I pushed.

As I stared suspiciously at the mirror, the bathroom door opened. Swallowing a yelp, I saw Miyu.

“What’s up? You must be exhausted.”

“I am, but when you wake up, I do too.”

True, Miyu often woke when I did. I felt bad for disturbing her sleep.

“What were you doing, Onii-chan?”

“Just using the bathroom.”

I glossed over admiring my newfound physique, wishing I was still buried in their breasts.

“Yamamoto-san?”

“Sleeping soundly.”

Her peace, likely from resolving our issues, was evident. From their talk, her romantic turmoil seemed settled.

“You okay, Onii-chan?”

“Surprisingly, yeah. After all that, my lower half’s still lively.”

I’d feared pain while peeing, but my cock and stamina had recovered astonishingly.

“Maybe the massage helped.”

“Massage?”

“While you slept, we rubbed and licked your body. With Kanade-san.”

“What?!”

They’d done that? After all that heartfelt talk, they’d messed around while moving me to the bed’s center. Why always when I’m out?

“So, you’re up for more sex, right?”

“Uh… well…”

Miyu crouched, taking my downward cock into her mouth.

Hamu… chuu… juru… chuppa…

“Hey, h-hey… Miyu…! We did so much already…!”

Her sudden blowjob got me hard, but starting sex here was unsettling. I stroked her head to stop her, pulling my cock out.

Miyu, lips still on my glans, glared up resentfully.

“…Not enough.”

I froze at her words. After all that sex, she wanted more?

“You creampied Kanade-san three times, but fell asleep before my third.”

“No, I…”

She wasn’t talking total ejaculations or volume. The promise of five creampies each left Miyu short, and she was upset.

“But I did you once before, the thickest one.”

“That’s separate. Five is five. As my lover, don’t you feel bad giving me fewer than your friend?”

“Well, when you put it like that…”

No reasoning could calm her. Her absurd logic made me feel guilty.

“But in Yamamoto-san’s room? She’s sleeping right there.”

“So, quietly. Hurry.”

Miyu stood, shaking her butt to entice me. What a lewd sister.

“Don’t be loud.”

“I know.”

Holding her hips, I thrust gently, unlike our wild bed sex.

“Ah… nn… Onii-chan’s… fully recovered…”

Hands on the washing machine, Miyu felt my thrusts, breasts swaying. She seemed happy just to have my cock, her frustration from the reconciliation plan unresolved.

“Aah… Onii-chan’s… big… feels… fuu… guh… hard to breathe…”

Though she looked pleasured, I noticed her tiptoeing, hips raised. Her tight vagina gripped me, the increased contact making her folds cling better.

I’d felt it with Yamamoto-san too—my cock had grown.

“Sorry, it might’ve gotten bigger.”

“Ugh… why do extra stuff… this… haa, fuaa, ah… too big for my body…”

Miyu’s small frame and naturally tight, unyielding vagina—despite our experience—confirmed her loli-like physique.

“But this is a side effect of your plan.”

“Ugh… didn’t plan this… haa… ugh, aah, ah… no, I can’t… haau…”

My larger cock, longer too, went deeper than intended despite half-thrusts. Miyu struggled to stay quiet, nearing her limit. Her vagina clamped, signaling climax.

I could still endure, but her quick orgasms were so cute, I got mischievous and decided to cum without warning.

“Ah, ah, I’m… cumming… haa, haa… ah, aah! Ahh! Onii-chan, nn, aah, inside… nn, nnn…!!”

As she came, I silently ejaculated. Shocked but forced into another orgasm, Miyu’s legs buckled, collapsing without strength to cling to the machine. Cum leaked from her unclosed vagina.

“Fa, haa, haa… Onii-chan, say when you’re cumming…”

“Sorry, got carried away.”

My sister, unable to resist cumming from a creampie, was adorable. She’d talked about depending on her lover, but no way I’d let go of this erotic sister.

“Doing it in someone else’s house, huh.”

Sex outside our home felt wrong, especially with the owner sleeping nearby. We’re quite the perverse couple.

“Well, it’s someone else’s house. Helps me stay sane.”

“True.”

After so many creampies, Miyu should’ve been a lovesick mess, but the unfamiliar room’s tension kept her rational.

“Let’s go back.”

“Yeah.”

We returned to the living room. Yamamoto-san was still asleep, breathing softly.

“She’s out.”

“Must be exhausted.”

“Especially mentally.”

Crying and being made to cry in one day—she’d be tired.

“Wanna do it here?”

“In front of her…?”

“Yeah.”

“Honestly… but…”

Having seen Miyu “stolen” in my half-sleep, I felt vengeful. Let’s do it.

“I’m awake, you know?”

Yamamoto-san’s voice startled me. Not sleep-talk—she was up, apparently for a while.

“S-Since when?”

“When you went to the bathroom.”

So… she heard everything, from start to finish.

“I heard you two getting cozy in the bathroom.”

“Sorry…”

I bowed deeply. Miyu, embarrassed, looked sheepish. Apologize too.

“Your closeness is nice, but…”

Yamamoto-san sat up, stretching her arms. In sage mode, her healthy, stunning physique stood out.

“I’m hungry. Let’s eat.”

“Yeah, let’s rest.”

“I’m starving, but…”

Lingering was fine, but it was morning. Even if her place was close, we had no time for breakfast with school prep.

“When are we leaving? School’s today.”

As they headed to the kitchen, I asked a reasonable question. But both Miyu and Yamamoto-san stared at me, dumbfounded.

“Did I say something weird?”

“No, Onii-chan, you’re planning to go to school?”

“You want to go that badly, Sotomichi-kun?”

“Huh? …Huh?”

I said something normal. Why was I being judged?

“Give up on school. Even you can’t make it.”

“I might be a bit late, but if we leave now, it’s doable.”

It was the first day. Both Yamamoto-san and I skipping would stand out. But Miyu, skeptical, pressed further.

“You’re doing four more rounds. Just a bit late?”

“What? Huh? …What?!”

Her unexpected words hit me. Yamamoto-san was fully on board, exchanging puzzled glances with Miyu.

I promised five creampies each. But the mood felt resolved—everyone’s issues settled, happy. Right?

“Your Onii-chan wouldn’t break a promise, would he?”

“I’m not one to talk, but… I wanted to be cherished a bit more for the last part…”

I was speechless. The fault was mine.

Miyu was right—failing a promise was unacceptable as her brother. Yamamoto-san expected it naturally, so I had no choice but to skip school and have sex with these beauties.

“Fine. I’ll call in sick…”

“Yay! Sex with Sotomichi-kun!”

“That’s my Onii-chan. Love that about you.”

“Haha… ha. Thanks.”

The girls were eager. Why should a guy care about appearances?

Sex with such cute girls—nothing else mattered.

“I’ll make a tasty breakfast for Sotomichi-kun.”

“Onii-chan, laze in bed and wait.”

These man-ruining beauties donned aprons naked, tying them in sync. Pressing their breasts through thin fabric, hands interlocked, they shot me playful looks.

“Morning menu: scrambled eggs on my stomach for Sotomichi-kun to eat with his mouth… and pancakes fed by Miyu-chan’s mouth.”

“Are you sane, Kanade-san?”

“You’ll never do this again, right? Think of it as a memory.”

“Can’t argue with that.”

“I’m… sleeping.”

Giving up, I feigned sleep as they headed to the kitchen, giggling.

Their newfound closeness echoed. My already depraved life was set to sink even lower.
