My Little Sister Is the Best F*p Material - Volume 8 Chapter 07: An Irredeemable Siscon Sister, a Best Friend Made to Cry by Lovey-Dovey Sex, and a Threesome in the End

Volume 8 Chapter 07: An Irredeemable Siscon Sister, a Best Friend Made to Cry by Lovey-Dovey Sex, and a Threesome in the End

It was a bizarre scene. In a cramped single apartment, three naked people on a bed: my classmate and fleeting lover, with whom I’d just had sex; my real sister, about to have sex with me as my true lover; and me, a guy who was a dull virgin just months ago, now entangled with two busty beauties.

“Miyu-chan, what… are you planning…?”

Yamamoto-san, at the bed’s edge, tried to calm her flushed body after I’d made her cum. More than Miyu’s presence, she seemed rattled by the idea of me and Miyu having sex right here.

“What? Well, for starters, I’ll make him cum with my mouth.”

Miyu gently gripped my cock, stroking it while answering casually. I was naked, as were the two girls talking, their bra-less breasts—round and heavy—swaying freely.

“With your mouth… you mean… fwe, a blowjob…?”

“What else? You’ve done it plenty with my Onii-chan, right, Kanade-san?”

“W-Well… yeah, but…”

Yamamoto-san was oddly flustered. Despite being the most experienced here, her tension was palpable, her heartbeat almost audible.

“Doing it on this bed… isn’t that bad…?”

Unable to address Yamamoto-san directly, I whispered to Miyu. Even if the situation made it unavoidable, this was her bed—where she’d sleep and maybe one day share with a future boyfriend. The memory of another couple (especially the only guy she ever truly loved and his sister) having sex here would be unbearable.

“Would it be bad if Onii-chan and I had sex on this bed?”

Miyu threw my question back at her nonchalantly.

“Uh… well… maybe, but…”

It was more of a “now that you mention it” reaction; her response was subdued. Her eyes weren’t on me but on Miyu—specifically, her naked body and the practiced hand casually stroking my cock.

“No, but… you two… are…”

Yamamoto-san hesitated, guiltily voicing her feelings to Miyu.

“You really… do that kind of thing…”

Her voice trembled, eyes downcast.

“You’ve known for ages.”

“Y-Yeah… I know, but…”

She hugged her chest, curling up like a mermaid, legs together. Seeing us siblings in the act was more shocking than she’d imagined.

As Miyu said, Yamamoto-san knew we had sex. The issue was it had only been words. She’d only seen us together twice—at the department store and home—where Miyu played the cool, caring sister. Despite her experience, unlike our wild friends, Yamamoto-san only knew normal sex. Our twisted normalcy was on us. Thinking back, she’d hinted at unease about our relationship before. And when she first learned we were intimate, she was more shocked than anyone.

“Onii-chan and I are siblings, and if not for your date, we’d be having sex daily. Yesterday, he was begging me for it, right?”

“Tch… summer’s ending, and I was pent-up…”

“Guess so. You came so much, yet you’re still this hard.”

“M-Miyu… ah, ahh…”

Miyu’s slick hand worked my post-sex cock, making lewd kocha kocha sounds to draw Yamamoto-san’s attention. Guilt from our repeated sex kept her from blocking her ears, her complex expression darting around.

“Half-assed sex left you unsatisfied, right, Onii-chan? I’ll make you cum properly. Come here.”

Ignoring Yamamoto-san’s feelings, Miyu got off the bed, positioning me kneeling at the edge. Bringing her lips to my cock’s tip, she glared up at me. Our hearts were in sync—I knew her look meant to show off our sibling bond to Yamamoto-san, and cumming too soon would earn her wrath.

“If I wanna cum, is your mouth okay?”

“Where else would you cum?”

“Well… with Yamamoto-san here…”

“Don’t mind her. Fill my mouth.”

Miyu’s sweet voice urged me as she opened wide, taking my cock deep.

“Hamu… churu… pa… an… jurur… jupp…”

Slow strokes, her tongue swirling, saliva making chupa chupa sounds. The lewd jurur, jub of her blowjob echoed, and Yamamoto-san, at the bed’s corner, averted her gaze. Occasionally, she’d glance briefly, blush deeply, and turn away, repeating the cycle.

“Ahh… ugh… Miyu, please, go easy… ah… aah…!”

“Nn… jurur… bu… chuu… Moan all you want, but don’t cum yet.”

“I-I know… I’m trying, but… kuh, ah…!”

“Hamu… jururu… jurur… chupp…”

Miyu sucked my cock shamelessly, ignoring that this was Yamamoto-san’s home. Caught up, I couldn’t hold back my moans. On her bed, where she was sidelined, our sibling blowjob played out boldly.

“Nn… amu… ju… pu… Haa, Onii-chan, feels good…? Nmu… jururu… chuu… nn…”

Miyu’s blowjobs were never intense, just soft with lots of air. But with her, even that hit my sweet spots, stoking my urge to cum.

“Too good… I’m at my limit…”

“Nn… chuu, pa. Geez, so fast. Fine, say my blowjob’s better than Kanade-san’s, and you can cum.”

“C’mon, still with that…”

“But my blowjob is better, right?”

“Well… yeah… I guess…”

No denying it. Glancing at Yamamoto-san, I saw a naked beauty, heartbroken, her face full of loneliness.

“Then cum like we practiced.”

Miyu grabbed my hips, swallowing my cock whole from her kneeling position at the bed’s edge.

Juu… chururu… hamu hero… churu… chuuu… chupp chupp…

“Ah… guh, ah, ah…!”

She took me to the root, barely moving her head, using her tongue to hit my sensitive spots.

“Aah, aah…! No, that’s… I can’t…!”

Her glare silenced my retreating hips, demanding I say it if I cum. Yamamoto-san, witnessing this, was red to her ears.

“Aaah… aah… feels so good… better than Yamamoto-san’s… fuu… aah…!”

Churu… hamu… chuu… Onii-chan… nn… rahee… chuu… chupp…

“Haa, aah… nothing feels this good… not with anyone else… haa… I’m cumming… cumming…!!”

I thrust my hips, rubbing my cock in her throat, unleashing my lust.

“Haa, aah, cumming! Cumming! Here it comes…!!”

Byu, doryuru, biruru, byuku, byubyu—!!

Once I spoke, the words fueled my excitement, and I poured a massive load into Miyu’s mouth. My thickened cock pumped out thick cum, flooding from my balls into her. She tightened her throat, holding as much as she could, savoring it on her tongue.

Releasing my cock, she opened her mouth, showing the sticky pool of cum. Yamamoto-san, unable to look away, was struck by the volume, thickness, and the declaration that Miyu’s blowjob was better, her lips pursed tightly to hold back tears. Her battered pride took another hit, but her guilt kept her blaming herself.

Miyu, done with the blowjob, turned to her. This wasn’t just checking Yamamoto-san’s state—it was purposeful.

Crawling onto the bed on all fours, Miyu nodded for me to move to the edge. I complied, freeing space. She crawled close to Yamamoto-san, grabbing both her hands.

“W-Me? What? Sorry, use the bed as you like…”

Yamamoto-san, fixated on her regret for clinging to me while watching our oral sex, couldn’t process the situation. Pulled to the bed’s center, she should’ve guessed Miyu’s next move with cum still in her mouth.

“Miyu-chan… fwe, ah, wait…!”

Miyu climbed over her, pinning her down, immobilizing her arms. Despite Yamamoto-san’s strength, guilt toward Miyu—the one she owed an apology to—kept her from resisting.

“Nn!? Nnn…! Ah… ngu…!?”

Without resistance, Miyu mercilessly thrust her tongue into Yamamoto-san’s mouth.

“Hey, Miyu, what are you…!”

In that glimpse, their lips stayed locked, not parting even a fraction, sharing my cum. Miyu’s hair hid their mouths, but the guchu guchu of lascivious saliva exchange was clear from the sound and movement. Miyu tangled her tongue with Yamamoto-san’s, sandwiching my semen, crushing it, forcing her to taste it. Their naked bodies writhed in pain and arousal, Yamamoto-san struggling to break free while Miyu pinned her down, limbs entwined.

“Ngu… nnn…!! Nn, nnn—!! Fu, n, nn… nnn…!!”

Yamamoto-san’s face twisted in anguish and pleasure. Having transferred all the cum, Miyu ended the tormenting kiss, releasing her.

“Nn… mu, chuu… puha. So, Kanade-san?”

Miyu, the aggressor, was breathless from exertion and arousal, her fair skin faintly flushed.

“This is Onii-chan’s cum when he’s desperate to impregnate. Realize how diluted what you’ve swallowed was?”

“Mugu… ugh… sniff…”

My heart ached as Yamamoto-san held back tears, her sniffles piercing. Made to taste regret and bitter cum, she was crying again—partly my fault, but this was too cruel.

“Only his sister can make Onii-chan cum properly. If you thought you ever satisfied him, correct that delusion.”

Unable to speak, Yamamoto-san nodded tearfully. Miyu cupped her cheeks.

“But I’ll admit your body and skills are impressive. If things were different, I might’ve let you be his fucktoy.”

For Miyu, who’d never allow others’ sex with me, this was high praise. Yamamoto-san, unaware, noticed Miyu’s tone soften, her tension easing.

“I’ll spare you swallowing.”

Miyu kissed her gently, unlike the forceful tongue-thrust, licking the cum with affectionate chuu.

“Nn… fu… ah… Miyu-chan, you’re too good at girl-on-girl…”

Chuu… nn… “I don’t mind. You’re so hung up on details, Kanade-san.”

“No, siblings, girls together… that’s not normal… ah… nn…”

Miyu, having cleaned the cum, kept kissing. Despite Yamamoto-san’s shock at same-sex kissing, the pleasure overwhelmed her resistance, and by the time Miyu pulled away, she seemed to surrender to it.

“Haa… haa… ugh… what do I do…?”

Yamamoto-san covered her face, curling up, guilty for enjoying a girl’s kiss—another piece of her normalcy shattered.

“Kanade-san, you’re in the way, so stay quiet in the corner.”

“Huh? Oh, okay…”

Obeying, she crawled to the bed’s edge, hugging her knees. Her breasts, pressed by her knees, looked fuller, and her wet slit glistened faintly in the shadow, soaked from Miyu’s torment.

“Um… what should I watch…?”

Drained of thought, she asked Miyu.

“I’m his sister, so I’ll just take care of his needs.”

Miyu’s gaze landed on my cock, unbelievably hard.

“I’ll make you cum again. Onii-chan, lie back, legs toward me.”

“S-Sorry…”

Guiltily, I complied, lying with my lower half at the bed’s center, offering my lustful cock to Miyu.

She leaned close, her youthful yet sharp face near mine. Her ample breasts and unfamiliar pale nipples stoked my desire irresistibly.

“…Uh, Miyu? What’re you doing?”

“Sex, duh.”

What kind of “duh” was that?

“Uh… s-sex? Okay… um, I’ve got plenty of condoms…”

Realizing she’d witness our sex, Yamamoto-san, flustered, tore off a condom from our stash and offered it to Miyu.

“What’s that?”

Miyu dismissed it, pressing her slit against my upright cock, leaning into me in a cowgirl position.

“But… you need a condom…”

“No impurities between me and Onii-chan.”

As Miyu lowered her hips, taking my cock’s tip into her slit, Yamamoto-san froze, pale.

She must’ve known Miyu and I had gone raw. But Yamamoto-san had a mental quirk—when faced with an unbearable truth, she avoided considering it until the last moment.

Even knowing Miyu was on the pill and this was safe, seeing sibling sex up close rattled her so much she couldn’t stay calm.

“You okay, Miyu?”

“I’m fine. One creampie? I’ll handle it with grit.”

Miyu went lovesick after a creampie, which could make this unmanageable.

“Even if you’re prepared, Miyu-chan… Sotomichi-kun’s creampie feels risky…”

Yamamoto-san’s timid comment, considering my cum’s volume and our chemistry, was reasonable, and Miyu seemed to agree. But still.

“Doesn’t matter. Honestly, I’m ready to get pregnant now. My resolve to carry Onii-chan’s child differs from yours, Kanade-san.”

Yamamoto-san fell silent, sensing the gap in conviction. Miyu likely had a plan to live happily even if pregnant tomorrow. I was confident we’d overcome anything together. With the pill making pregnancy near impossible, raw sex for pleasure was a no-brainer.

“Can’t wait any longer or I’ll go crazy, so I’m putting it in.”

Miyu, sharing only our genitals’ entrance, dripped with arousal. Last night’s missed sex hit her hard too, her body’s heat told me. So, I thrust my hips, entering her.

“An… nn, aah…!!”

Zububu—Miyu arched back, moaning as my cock slid in.

“W-Wa… ah…!”

Yamamoto-san started to say something but couldn’t stop our raw sex.

“Miyu, haa… feels so good…!”

“Fu, aah… Onii-chan… so big…!”

I thrust selfishly, aiming for rough, fast pistoning to overwhelm Miyu with the act itself, not my cock’s feel.

“Fu… ah, aah… Miyu… kuh… so good…!”

“Haa, haa… Onii-chan… hitting deep…!”

Even raw, I thought we had control in front of Yamamoto-san. But my estimate was naive.

“Kuu… haa… your pussy’s so wet… sucking me in…!”

“Fa, ah, Onii-chan, no… stop a sec…!”

Miyu, who’d surrendered to me, grabbed my arms, stopping my hips.

“Haa… Miyu…? What’s wrong?”

Her trembling body propped up on her hands. Peering at her face, I saw her surrender faster than ever, her expression lovesick.

“Sorry, Onii-chan. I can’t hold back.”

Her apologetic voice contrasted her hips’ small mozo mozo movements, greedily savoring my cock’s shape.

“Wait, Miyu. After all this planning, making Kanade-san cry, showing off sex, and now you’re losing it to lust?!”

This hopeless siscon sister, after orchestrating everything, threw it all away to her desire.

“Ugh… but you were with Kanade-san so much, I had to get off alone tons…! With your big cock inside… I can’t resist…!”

Miyu gradually shed her intellect, regressing into a childlike state. Then, squatting, she began moving her hips up and down.

“M-Miyu… that’s no good… ah, aah…!”

Bachun, bachun—her ass slammed down like a stamp. I hadn’t expected Miyu to take charge in cowgirl, and my cock, overwhelmed by pleasure, swelled to its blood-flow limit.

“Ah, shugo… big… no, ah, ah…!”

Miyu angled her hips to let my glans graze her G-spot, then plunged it deep to prod her cervix, grinding with deliberate insertion. Meant to show off intense sex for Yamamoto-san, she seemed to forget that, lost in savoring my cock.

“My tummy’s… so full… fa… ugh… it’s tight… I love it…”

Her tight vagina squeezed my cock, her voice dripping with lust, consumed by carnal desire.

“Onii-chan, just kiss me already… cum deep inside…”

“If I do that, Miyu, you’ll…”

“Just do it… Onii-chan…”

Her childish pleading was so cute, I wanted to lose myself in her body. I’d let this orgasm happen freely.

“You’re… such a hopeless sister… nn… chuu…”

“Fumu… nna… Onii-hyan… shuki… nn… chupp… hero chuu…”

Stacked vertically, tongues entwined, no pistoning—just grinding my glans against her cervix.

“Nn… ah, aah…! I love that… more, feels good… hia, ah…!”

“Miyu, Miyu… so good… fuu… aaah…! Your tiny body, taking me so deep… haa, aaah… kuh… it’s all so good…!!”

Sex with Miyu felt wrong, and that thrilled me. Sibling sex, penetrating her small body—both drove me wild. Holding her petite frame heightened the taboo, and we embraced in shared depravity.

“Nn… jurur, chuu… puha… Miyu… Miyu…! I’m gonna cum… inside you…!!”

“Nnaa… aah, aaah…!! Cum, Onii-chan… haa, shoot your semen…!!”

Stirring her honey pot with my erect shaft, her juices splashed my abdomen. Prioritizing her cervix over thrusting, Miyu climaxed first, her tight vaginal contractions pulling me to release.

“Miyu… cumming… aaah—!!”

Doku, doku, doku, dokun—my cock pulsed, shooting semen through my urethra, filling Miyu’s packed vagina instantly. Thick cum invaded her womb, seeking her eggs.

“Aah… haa… Miyu… that was amazing…”

“Faa, haa, haa… Onii-chan… I love you… nn… chuu…”

Kissed by Miyu, I poured love into her as I’d poured cum. Her sweaty skin glistened, droplets pooling at her nipples. Wiping them, she writhed sensually. With such a cute sister, I needed nothing else. Feeling her warmth in our kiss, I was in bliss.

I remembered Yamamoto-san when a condom wrapper hit the floor. Stunned by witnessing my creampie, she froze. Miyu, perhaps recalling her presence, lifted her weakened hips to pull off my cock, letting hot fluids drip onto my abdomen, forcing Yamamoto-san to see the proof of my seed in Miyu’s womb.

“I’ll clean Onii-chan up.”

Miyu’s unusually gentle voice soothed me. Gazing at the cum pooled on my abdomen, she licked my still-hard shaft.

“Thanks… Miyu. Feels so good.”

“No problem. It’s for you. Still hard—gonna cum again?”

She teased.

“Maybe one more…”

“One’s never enough with you. Get it out before I lose it.”

Our banter continued, but this was someone else’s bed. Yamamoto-san, its owner, had watched this saccharine sex unfold.

“Ugh… u… uuu…!”

She cried again. Seeing her brother pour semen into his sister’s vagina—an immoral act—stirred shock, sadness, or some indescribable emotion, making her tear up.

That should’ve been a normal human response.

But this seemed to be Yamamoto-san’s breaking point, where her mind discarded everything.

“Muguu… enough! Getting all lovey-dovey on someone else’s bed!”

Cheeks puffed out, regressing as much as Miyu, she tossed the condom aside and charged at us.

“You two, doing such lewd things as siblings! I feel stupid for agonizing over this so seriously!”

She pouted, venting. Miyu gave her a sly, meaningful smile.

“Finally facing reality?”

“I get it—I can’t beat your lovey-dovey vibe.”

Yamamoto-san sighed, exasperated. Miyu cut in with her usual sharp words.

“Think about how I felt. Do you know how embarrassing it is to have someone watch me and Onii-chan have sex?”

“Ugh… sorry about that.”

The two, once at odds, had somehow bonded. They’d both been carrying heavy burdens.

“Hey, can I help clean up?”

Yamamoto-san poked my erect cock, asking Miyu.

“Well, you seem repentant, and I know I went overboard, so I’ll allow it this time.”

“Yay!”

Miyu let Yamamoto-san clean the cum off my shaft and surroundings, while she licked the semen from my abdomen. Mixed with her juices, Miyu handled it fine.

“Sotomichi-kun’s… still so hard… haa… mu… jururu… chupu…”

“Ugh, ah… Yamamoto-san, that intensity…!”

Her eager sucking stretched my cock, while Miyu, unbothered, licked up the cum, then moved to my chest, sucking my nipple with a jubu sound.

“Ah… aaah…!!”

The sudden pleasure made me jump. Nipple and cock stimulation drove me to uncontrollable arousal. Thinking it was over, I’d let my guard down—this was a dangerous spot.

“Onii-chan, no cumming for a while.”

Miyu’s absolute command bound my body. Ordered to cum, I’d release endlessly; told not to, I couldn’t, no matter the stimulation. Stripped of release, I was ravaged by Yamamoto-san’s cock-sucking and Miyu’s ball-licking, a double assault.

“Aah… ah… aaah…!! No, that’s… haa, aaah… wait… ugh, guh… uuu, haa, aah…!!”

From tip to base, their tongues teased with chiro chiro licks, then engulfed me with vulgar sounds. Simultaneous stimulation overwhelmed me as Miyu joined Yamamoto-san, licking my cock from both sides.

Yamamoto-san’s mature, gentle face and Miyu’s youthful, defiant eyes locked onto me. Their tongues lapped my cock, my lower body trembling.

“I… guh, aah, haa… I’m cumming… cumming, ah, aah—!!”

My cock pulsed, but no cum came, only mounting lust. Yamamoto-san dragged her lips along my shaft, Miyu sucked the glans, and when their faces neared, they kissed with my cock between them, ravaging me.

I screamed in pleasure, denied release, and finally cried too. The double blowjob torment ended.

“You’re too loud, Onii-chan. This is an apartment.”

“I’ll get the complaints, so keep it down.”

The two crawled toward me on all fours, flanking my supine body. Miyu’s petite frame with oversized breasts asserted itself on my right. Yamamoto-san’s sultry, voluptuous body, radiating sensuality, was on my left. They dangled their rewards before me, with no intention of letting me cum, yet teased me with their breasts.

“…Ahh… showing me such erotic things…!”

I grabbed their massive breasts instantly, sucking Miyu’s nipple, with Yamamoto-san’s still free—a luxury I’d never know again.

“Nn, aah…! Onii-chan, too eager… nn, ah…!”

“Grown man latching onto his sister’s tits with no shame—so charming, Sotomichi-kun… hia, ah, haha, nna…!”

Sucking their nipples alternately, my hands overflowed with flesh, savoring ultimate bliss. Then, my neglected cock was gripped—top and bottom, glans and base—feeling like a handjob. I realized they were stroking me with their toes.

“Ah, ah, aaah…!! Crap, aaah… that… gah… aaah…!!”

These lewd beauties crawled closer, blocking my view with their breasts, while their raised legs sandwiched my cock between their toes. The limited contact, doubled, was intense.

“Haa, ah, no, I can’t…! I wanna cum… let me cum…!!”

Forbidden by Miyu, I could only dry-fire, yet they kept foot-jobbing me.

“Sotomichi-kun, your precum’s so thick it’s like you’re already cumming.”

As I writhed, my cock grew slicker, their foot movements shifting from rubbing excess skin to stroking the entire shaft intensely.

“Ah, aaah, ah, nnaah…! No… gaaah…! I’m dying… I wanna cum, let me cum…!!”

“Geez, Onii-chan.”

Screaming from unbearable arousal, Miyu, still foot-jobbing, leaned close to my ear.

“Is that okay? Cumming so soon?”

Her whispery breath grazed my earlobe.

I jolted, and Yamamoto-san, seizing the chance, smirked mischievously and approached my other ear.

“She’s right, Sotomichi-kun. Cumming when it feels this good? Such a waste.”

I couldn’t stop groping their massive breasts. Both ears dominated by different voices, my most sensitive spots relentlessly stimulated. Alone, their force might’ve let me escape, but together, it matched a handjob’s pressure.

“Might as well… lick your ears too.”

Miyu whispered in one ear, and as if their minds were linked, Yamamoto-san licked the other.

“Nn chuu… hero rero… nn… chuu… Sotomichi-kun… staying so hard, good boy… hamu… churu… paha…”

A shiver ran through me, goosebumps like never before, my voice hoarse. Miyu blew air to push me further.

“Fuu… haa… Onii-chan… nn, chuu… hero… you love this too… ero rero… nmu… chuu…”

No rest—they licked my ears from both sides. Then they teased my nipples, attacking every erogenous zone. Scratching or pinching lightly, my erect nipples were trampled by their warm hands, dignity and all.

“Aaagah… haaaah, no, I can’t… I’m cumming… cumming… let me cum… I need to cum…!!”

Cumming wouldn’t end it. The pleasure of semen flowing through my urethra was the climax; without it, orgasm only amplified the torment. My body craved stimulation, instinct demanded release, and the contradiction pushed my brain to a feverish breaking point.

“Nfu. Can’t help it, huh?”

Miyu sensed my dangerous state.

“Then, Onii-chan, let it all out.”

Miyu and Yamamoto-san extended their tongues, rero rero, violating my ear canals. My nipples ravaged by their fingers, the pleasure of groping their breasts faded as they furiously stroked my cock with their feet.

“AHH—gahaa, aaah…!! It’s coming… aaah, haa, guaaah…!!”

Dopyu dopyu dopyu, byururu, byu—byubyuru, byuku, dobyuru, byu, byu—!!

Cum sprayed wildly, soaking me, Miyu, and Yamamoto-san in sticky white. They exchanged gleeful looks at my near-eruptive ejaculation, then meticulously licked the cum off each other.

Yamamoto-san no longer cared about licking another girl. After cleaning me, they positioned me in the center, knelt, joined hands, and pressed their breasts together, sharing cum in a tongue-heavy kiss.

“Haa… haa… aah… gahaa… I’m… dying…”

Beneath them, I was breathless, exhausted beyond future orgasms, dazed. Even after Miyu swallowed what Yamamoto-san couldn’t, they kept kissing passionately, and I cursed myself for getting aroused.

“You two are way too into kissing, aren’t you?”

“Nn… mu… chuu… Not true, Sotomichi-kun.”

They stopped, pulling my arms to help me sit up.

“Right. It’s for Onii-chan.”

“Huh? Me? I don’t have that kink…”

Their beauty made their kissing hotter than any AV, I’d admit.

“Not that. This.”

Miyu leaned in, kissing me deeply, as if making Yamamoto-san indirectly kiss her.

“Nn… nnn, ah… Miyu, what’s with this…!”

“Nfu. Feel anything?”

“What… nothing special…”

Wiping my lips, I realized what she meant.

“Wait… no bitterness…”

It felt sweet, despite Miyu having cum in her mouth.

“You don’t like kissing after a blowjob cum, right, Sotomichi-kun? So we cleaned each other’s mouths.”

Yamamoto-san added, “But we swapped a lot of saliva,” sticking out her tongue.

“Oh… I thought Yamamoto-san was…”

“No way! Geez, how rude… Though, with Miyu-chan, maybe I wouldn’t mind.”

“Please don’t think that.”

I resigned myself—threesomes inevitably involved girl-on-girl action.

“By the way,” Yamamoto-san said, shifting the mood ominously.

“We’re still… under that contract, right?”

She tilted her head, finger on her chin.

“Well, yeah,” Miyu replied.

“So, I can still have real sex with Sotomichi-kun?”

“A promise is a promise. I won’t stop you.”

I gaped. “…Huh?”

“Um… if possible… I’d like it raw…”

“No way… that’s one thing I can’t yield on…”

Their conversation was incomprehensible. My brain refused to process it.

“Please! I’m begging!”

“Even on the pill, letting Onii-chan’s sperm in your vagina is something I can’t allow as his sister…”

Miyu glanced at my now-limp cock, then lit up with an outrageous idea.

“But since Onii-chan’s sperm seems weak now, I might just allow it.”

“Really?! Yay!!”

I wished she’d say it was a lie.

“No… come on, I can’t. That wasn’t my first today…”

“You don’t need to cum tons like usual. Just get hard and cum in Kanade-san’s vagina.”

Miyu soothed me lightly. Why was she siding with Yamamoto-san? Guilt for making her cry?

“There’s been a lot, but haven’t you just been sleeping with tons of girls, Onii-chan?”

“That’s… not wrong, but I worked hard too…”

True, as Miyu said. But it was all her orders, so her saying it felt off.

“I’m not blaming you. That’s your role.”

My role in her plans was to fulfill every girl’s desires, mostly through sex, surrendering my body to their lust.

“You should fulfill that duty properly.”

I couldn’t argue.

“So, Kanade-san, how many times do you want with Onii-chan?”

“Um… I shouldn’t get greedy, right?”

“I don’t want you to have regrets. Go to your limit.”

“Then, five creampie sex sessions, followed by full-on service to Sotomichi-kun!”

“Got it. As his sister, I approve.”

I’d die.

“Kanade-san, lie back on the bed.”

“Me on bottom? Okay!”

Yamamoto-san lay down happily, spreading her legs for me. Miyu climbed atop, their massive breasts squishing together.

“Alright, Onii-chan, five times with Kanade-san. Alternate with me.”

“Huh… what…? With you too…?”

Their disregard for my body’s limits made me dizzy with despair.

“Planning to only do it with me when your lover’s right here, Sotomichi-kun?”

Yamamoto-san teased, backing Miyu. They’d forgotten their rivalry, reduced to wanting sex with me, their brilliant minds wasted.

“I’m gonna die from some disease soon…”

But before me were two stunning beauties, naked, entwined, gazing expectantly. Their dripping slits, spread invitingly, oozed with anticipation.

“Onii-chan…”

“Sotomichi-kun…”

Two soft, lascivious bodies stacked together. Faced with such a feast, my cock stood rigid, veins bulging, flaunting itself to them.

“If it’s like this… I’ll go till I pass out…!”

This was just the start. In this cramped room, I’d face a pleasure hell worth dying for with these three.
