My Little Sister Is the Best F*p Material - Volume 7 Chapter 09: My Sister at the Love Hotel

Volume 7 Chapter 09: My Sister at the Love Hotel

Leaving the spa, Miyu and I held hands, heading toward a love hotel in the bustling city. It was well past dusk, and the urban sky, unusually clear, sparkled with stars.

“You’re really good at this sibling thing, huh?”

At a crosswalk, waiting for the signal, Miyu clung to my arm. Her cleavage, deliberately pushed up, swelled like a squished rubber ball.

Such a bold move to catch her brother’s attention—admirable for my sweet sister. With her pale, shut-in complexion, her slit and breasts glistened like airbrushed photos. Combined with her soft, lolita-like flesh, her very existence felt unfair. Just recalling her smooth privates was enough to make me hard.

“What’s ‘sibling thing’?”

Hiding how her naughty teasing nearly broke me, I asked about her strange new term, wondering if it meant indulging her requests, like heading to a love hotel after an intense creampie session.

“Like raping a friend for your sister.”

“Guess I’m a pretty accommodating brother…”

This sister—engaging in shady acts with girls, making me sleep with others, and causing chaos in her class. Yet, loving her as she is, maybe I’m not normal, as Yamamoto-san said, or just a hopeless siscon.

“I’ll keep indulging you forever.”

“Nice!”

Miyu hugged my waist from point-blank range, bold despite the scattered passersby. Then, blushing, she pulled away and stepped onto the green crosswalk.

Her open affection warmed me. Sure, lust played a part, but her words made it feel like we were lovers. More like mischievous partners, though.

“By the way.”

As we neared the red-light district, Miyu spoke up.

“What kind of love hotel are you taking your sister to?”

Her question jolted me—she was toying with my pure heart. Her calm tone belied her ongoing brother-loving mode, her intense gaze screaming “love, love, love…”

Her mind must be flooded with erotic fantasies. If I could tap into it, a tidal wave of lewd emotions would probably fry my brain.

“All love hotels are the same. Unless it’s for kinky stuff, it’s just a bath and bed for two.”

“Huh, really?”

Miyu lacked sexual knowledge beyond what she learned for my “education” or her experiences with Haruka. Without those, she’d still be a pure, innocent girl.

“Lots of sketchy shops around here.”

“We’re in the heart of the red-light district.”

Love hotels clustered in one area, separated from regular businesses like restaurants by the station, so passing adult shops was inevitable.

Noticing Miyu staring at something, I followed her gaze to a second-floor sign: “Image Salon ~Sister Paradise~.” A sensual service offering cosplay “sisters” in school uniforms, aged twenties to forties.

Confirming I saw it, Miyu tugged my hand, meeting my eyes, asserting her presence.

“Sister Paradise, huh?”

“Yeah, we can’t lose to that.”

Unsure how to respond, I voiced a vague rivalry. Miyu clenched a fist, agreeing, “Right!” No imaginary sister here—just my real, underage, loli-beauty sister who genuinely loves me. Creampie sex with her? That’s paradise. No competition.

Chatting nonsense, we reached the love hotel. I stepped through the frosted glass auto-door, Miyu following.

The room would be ready after cleaning, so we waited a few minutes before choosing. I handled check-in with practiced ease, and we rode the elevator together.

“You’re so used to love hotels…”

Her tone suggested disbelief that her once-shy brother, who’d barely talk to girls without her, was now so comfortable.

“Sorry about that.”

My experiences with Sachiko and others were a net positive. They built my confidence as a man, but if I’d only been with Miyu, I might’ve questioned loving my sister.

“Bringing my real sister to a love hotel… is that okay?”

Muttering as I unlocked the room.

“Didn’t say ‘no sisters allowed.’”

“You mean ‘no escorts.’”

Unlocking, we kicked off our shoes and entered the familiar bedroom.

“You can see me as just a sister or a sister-shaped sex toy.”

“Keep talking like that, and I’ll really use you as one.”

My playful threat earned an expectant glance. Sadist or masochist?

Right, she’s in instinct-driven mode, mixed with her neutral self—lustful, brother-obsessed, eager to make me cum.

“You know I love lolita cosplay, right?”

“Yeah.”

She even masturbates to her cosplay mirror image.

“Maybe that’s why being treated as a sex doll feels… objectively exciting.”

“Kind of get it, kind of don’t.”

Her unique fetish was clear—not quite rape fantasy, maybe “love doll desire.”

“Oh, Onii-chan, condoms!”

Jumping onto the bed, she grabbed a wrapped condom from the tissue box.

“Games and anime are all about creampies, but in real life, condoms are kinda hot, right?”

True, condoms in eroge are a hassle, but in reality, the anticipation adds a special thrill.

“Putting on a condom is prep for insertion, right? Agreeing to it’s like saying sex is okay. That’s what’s erotic.”

I’d thought this during our first time. A condom was like a sex permit.

“Hmm.”

Staring at my crotch, she placed the condom on her stomach and lay back, arms raised, gazing seductively.

“M-Miyu…?”

A busty sister with long hair splayed on the sheets, fully clothed, no underwear peeking. Yet…

“Onii-chan, here’s a condom.”

Her repeated words, pointing to the condom, sent shivers through me, flipping my lust switch.

She was inviting me—intensely. Swallowing hard, I saw a sister ready with a condom, her vagina likely dripping with juices like lube.

A love doll, packaged for immediate use, begging, “Use me.” Her body screamed it was for my pleasure.

Such an earnest plea. Without words, just a condom on her stomach, she conveyed her desperate need for sex.

“If you insist, I’ll use you.”

Stripping my lower clothes, I climbed onto the bed to use my sister as a sex toy. My penis ached with erection.

“Cum in the condom?”

“No way. I’ll get mad if you do.”

Even as a sex doll, she wouldn’t budge.

“I’ll go raw when I’m close.”

A brother indulges his sister’s whims. Creampie for intercourse, oral for blowjobs—that’s our rule.

I leaned over, sliding her panties aside to insert. As my tip entered, she closed her legs, resisting.

“Ah… m-my clothes…”

She mumbled awkwardly. The mood made her want to dive in, but her dislike for dirtying clothes made clothed sex tough.

“If you’re a sex doll, I’d enjoy you dressed.”

“Ugh… that’s…”

She’d wear lolita cosplay for creampies eventually—this was practice.

“You’re here for my ejaculation. Just lie there and think of that.”

“Okay.”

Relenting, she relaxed, staring at the ceiling. She’d actively made me cum before, but now, she’d let me use her solely for ejaculation—a first. Not lover-like, but this was how we loved.

“Miyu, I’m putting it in.”

Lifting her legs, I slid deeper slowly.

“…Ah…!”

Her faint moans. Trying to act doll-like, she suppressed her voice with a blank face—erotic in its own way.

I started thrusting in missionary. I discovered clothed sex’s allure—inserting into Miyu, still in her date outfit. Parading my cute “girlfriend” at the aquarium or amusement park, now doing obscene things to her.

“Aah… Miyu…!”

Ignoring juices splashing her skirt, I thrust. Her clothed breasts jiggled with my movements, pushed up to flaunt their weight.

“Nn, nna… ah… ugh… nn…”

The fresh clothed sex heightened her sensitivity, yet she stifled her voice. Her enduring pleasure was adorable, so I targeted the edge where her moans leaked.

“Ah… ah… ugh… ah…”

Using half my length, I varied my strokes messily, making it a mechanical in-and-out.

“Ah…! …Fua…”

Still, her vagina clamped tight, her gushing juices conveying overwhelming pleasure.

Our first time was cold, like sending eroge text, barely support. Now, she accepted my cock, becoming my sex toy.

Not lover-like at all, but during this sex, Miyu felt more precious than ever.

“Miyu, I love you…!”

No matter how improper it’s called, I feel the deepest love when we’re having sex. No matter how erotic things get with others, nothing surpasses the thrill of being with my sister. This lewd sister, whose naughty nature reveals itself beneath her facade, is someone I want to do dirty things with countless times.

“…Ah, a… Onii… chan…”

Miyu’s face flushed red, her body jolting as I thrust my penis inside.

“Aah… ah…!”

She was feeling it—accepting my affection, her arousal amplifying her sensitivity. More than sweet words, our sibling bond deepened through this physical connection. That’s why we were irreplaceable to each other.

“Ugh… ugh… a… uuh… nn…”

Even as her sensitivity spiked, she tried staying unresponsive. Her clenched hands trembled with effort, as if focusing elsewhere was the only way to resist climaxing.

“Feels so good… Miyu…!”

I kept rubbing my cock against her slick walls. Her tight vagina, clinging despite repeated thrusts, sparked guilt from rough handling, fueling my arousal and making my penis swell.

I could do anything to this sister, no matter how wrong. That sadistic urge treated her like a tool for pleasure.

“Uuh… nfu… ah…”

Miyu regulated her breathing to endure the pleasure, but her vagina spasmed, on the verge of climax. Her shyly averted gaze contrasted with her body’s intense response, driving me to the edge.

“Ah… fugu… nna… hya, no, stop…!”

Sensing my excitement, she struggled against the surging pleasure, stiffening to suppress her voice.

But my relentless thrusting broke the dam holding back her orgasm.

“Nn…! …N—!”

Stifling her breath, she arched slightly, climaxing discreetly. Excess juices seeped from our joined parts.

“Your climax is so cute, Miyu.”

Praising her, she grimaced awkwardly and looked away.

“Just part of the service.”

Her flimsy excuse barely hid her embarrassment. A girl’s climax undeniably excites a guy.

How long could she resist?

“Can you hold out if I go deep?”

“I can try unless you grind my womb.”

That was the spot—her womb was like a switch for forced climax, though I’d only targeted it to finish before.

“I’ll thrust all the way in. Try not to cum.”

“What…! No way, that’s impossible…!”

“Maybe you just think that. You might manage.”

Her arousal from reproductive acts was just a pattern. Without the buildup, it might not hit as hard.

“Try holding out for a minute.”

She’d made me cum in under a minute before. If she climaxed within a minute despite resisting, our dynamic might feel fairer.

“Here I go.”

“O-Okay…”

I leaned over, aligning my penis vertically with her slit, pressing our bodies together. Feeling her warmth, I sensed her womb’s entrance with my glans. That was it.

“Nn…”

Lips pursed tightly, she reacted faintly. She felt my penis hitting her spot. Pivoting from the base, I rubbed my hips against hers, moving up and down.

“Ah… ugh… nn, nn…!”

She grabbed my arms, trying to lessen our contact to dull the sensation, but I pressed on.

Not vigorous—almost no back-and-forth, a motion some might see as resting. Yet…

“Hiaa… ah, nn, ah…! No… stop…!”

She couldn’t hold back her voice. Her tight vagina, stretched by my thick erection, made her womb’s stimulation overwhelming compared to intense sex.

“Haa… aau… nn, ah… aah…!”

Her body convulsed, gripping my hands. Barely thirty seconds had passed.

“Miyu, can you hold on?”

“Impossible, impossible…! I’m… gonna cum…!”

She knew her limit. I kept the steady tempo, targeting her womb until her climax.

“Ah, ah, aah…! Hya, nooo…! Hic… I’m cumming…!!”

Tensing her lower body, knees closing, she shuddered violently. She climaxed in under a minute.

“Hau… aa… really, impossible… I can’t resist this…”

Her womb was a forced climax switch. Cumming in under a minute with such small movements? My sister was too adorable.

But I’d moved to please her. Using a girl as a sex toy was harder than I thought, especially a lover.

“Next, I’ll cum. Going in raw.”

Pulling back, I removed the condom, reaching under her skirt.

“Just lie there. I’ll undress you.”

“Eh… ah, okay…”

She stayed still as I removed her panties, her expression uneasy. Being undressed while lying down was far more embarrassing than doing it herself.

“Hey, Miyu.”

“Hm?”

“I’m really just gonna cum.”

My curt declaration made her tighten her cheeks to hide her anticipation, turning away coolly.

“Go… go ahead.”

Barely masking her shy tone, she surrendered her body. Since she was trying so hard as a sex toy, normal sex would be rude.

No one inserts a penis to please a sex toy. I’d just rub my shaft to ejaculate.

“Fuu…”

My penis slid quietly into her soaked vagina, wrapping my shaft stickily. The raw friction leaked something close to semen. Her smooth slit taking my grotesquely erect cock was always thrilling.

The more I rubbed, the more her juices lubricated, squelching as I thrust. Focusing only on my pleasure, I silently pumped my hips.

“Nn… aa… ih…”

Her sultry breaths echoed as moans in the spacious bedroom. Without loud gasps, they were more than enough to arouse me—more exciting this way. It felt incredible.

A girl’s pleasure boosts a guy’s, but that’s just dominance being satisfied. The sensation of her folds clinging came from focusing on thrusting.

Using my sister as both fantasy and tool for selfish masturbation? Ultimate pleasure. Creampie, no tissues needed. I wanted to cum fast.

Her sensitive vagina, post-climax, tightened around my raw cock. Unable to suppress her reactions, her mixed pleasure and confusion drove me wild, making me leak a bit of semen.

Suppressing the urge to please her, I thrust like jerking off with my hand, targeting my glans’ sweet spot. My quick climax usually worried me about finishing too soon, but now, no restraint was needed. I could cum whenever, however fast. That freedom barely held back my ejaculation.

“Hi… hiu… I’m…!”

She covered her mouth, trying to stay a sex toy. Despite likely hitting another climax from deep thrusts, she endured for me. Normally, we’d sync our climaxes, but I wanted to ejaculate watching her stifle her moans.

“Fuu… ugh, ah… I’m cumming…!”

Not waiting for her climax, I ejaculated. Semen poured into her vagina, my warmth mixing with her silent body.

Squeezed by her tight walls until the last drops, I slowly pulled out. Aroused to the brink by my ejaculation, she’d held back her moans to the end.

“…Haa… so much came out…”

Despite not climaxing, she smiled, satisfied. She really loved making me cum.

“Was that okay?”

“Could’ve been more detached.”

“How do you get more…?”

Sex inevitably carried some intimacy.

“You’re still hard, huh?”

“Yeah, it felt better than expected.”

The thrill of selfish ejaculation lingered in my erection.

“Let’s make you cum again.”

Sitting flat on the bed, she wrapped my knee-standing cock with her small hands. The mix of juices and semen made it perfectly slick for a handjob.

“Handjob, okay?”

“G-Got it.”

Ignoring my tension, she started stroking.

“Oh… ooh…”

A nostalgic sensation—her handjob was from before she’d allow blowjobs. Stroking with a blank face… it hit hard.

“Feel good?”

“Of course. Your fingers are so delicate… hitting just the right spots… ah…”

“Good.”

Mixing finger twists and palm rubs, she steadily pleasured me. The room fell silent, filled only by the squelching of her handjob and my escaping breaths.

“Ugh… fuu…”

Her hand covered half my shaft, passing the glans’ ridge with a clicking sound, like rubbing stone beads. I’d expected endless lovey-dovey creampie sex in a love hotel, but here I was, kneeling, while she became a mechanical cock-stroker. Less sex toy sister, more android or handjob maid.

What thrilled me most was her wide eyes, which had made me cum countless times, blinking impassively. Her cold detachment as she stroked ignited my lust.

“Ugh… ah… Miyu, I might cum soon…”

My third ejaculation, so soon after the last, was already near. Unlike her cold gazes from before, her blank face now radiated brother-loving vibes telepathically, even without smiles.

If I let my sister keep giving me a handjob like this, I won’t last more than a few minutes. Cumming now would splatter her clothes, so I need her to open her mouth and let me finish there.

“Gonna cum already?”

“Sorry for being so quick, as usual…”

“I’m used to your early finish, so it’s fine.”

Her polite kindness hits deep. And it’s arousing.

“Then, cum inside me.”

“Wha… if you’re okay with it, I’m game…”

Back then, she’d have let me finish in her mouth and called it a day. But this time, her intent seemed different.

“Here you go.”

Stopping the handjob, she got on all fours, presenting her hips.

“Hurry, hurry.”

“G-Got it.”

Lifting her skirt, I thrust my near-climaxing cock deep inside.

“Uah… this tightness right before cumming… it’s intense…”

It was like the first time I used a condom, climaxing from the pressure alone. My handjob-sensitized penis, squeezed by her tightened vagina in doggy style, urged an instant release.

Holding back wasn’t wanted. Get hard, insert, feel good, cum—that’s the mechanical process she expected.

“Nn… Onii-chan’s filling my stomach so much…”

“M-Miyu… I’m… gonna cum…”

“Go ahead. Let it out.”

With my raw cock inside and her saying that, there was no holding back.

“Aah… Miyu… I’m cumming, cumming… ah… aaah…!”

With pathetic thrusts, I managed a few strokes before trembling, releasing small spurts repeatedly.

“Ah, ah, Onii-chan’s sperm, shooting inside.”

She accepted my ejaculation with a joyful tone. Pulling out, an astonishing amount of semen flowed out despite the brief sex.

“Felt… so good…”

“Hehe, I loved you cumming in me.”

Maybe because I’d grown used to her cold treatment during ejaculation, even this subdued sex satisfied me. How far has this sister warped my fetishes?

“Your quickness makes this kind of sex possible. Lucky, huh?”

Her polite tone again. I might love her even more.

“You satisfied, Miyu?”

The sex felt half-finished, and with her recent pattern of intense climaxes, she might feel unfulfilled.

“Well, I’m happy with sex with you, but…”

She hesitated, continuing shyly.

“My mouth’s been neglected lately…”

Her honest confession reminded me of something crucial. Just as cumming in her mouth was special for me due to past experiences, it was a cherished act for her too.

“You’re right.”

Maybe saving up for a while and cumming in her mouth would make her happier. She loves thick, gooey semen, and I’d find it more exciting.

“Let’s hit the bath first.”

We were still clothed, and she’d probably dislike sucking a penis fresh from her vagina.

After filling the tub, we entered the bathroom. I rinsed off, passed her the shower, and got in. She tied her hair up, letting water cascade over her shoulders, flowing along her curvy form. Droplets fell from her full breasts like clear springs.

“Hm? Something up?”

She noticed my heated stare.

“Just… your naked body is so erotic…”

“Really, now?”

Yes, now. I know it’s obvious, but her allure never fades. Her smooth, lolita-like body with that fullness is unfair.

“Mind me looking?”

“Nope. Look all you want. You’re the only one I’d show.”

She stopped the shower, displaying her wet body, hiding nothing. Confident like no actress, she probably loved the praise, even if “erotic” is a questionable compliment for a girl.

“But I can’t see down there.”

“You see it during sex, so that’s enough, right?”

She replied curtly, joining me in the tub. She knew the difference between catching glimpses during sex and her deliberately showing her privates. If she spread her soft slit for me, I could live off that image forever.

“Onii-chan.”

Her scolding tone snapped me out of it—I was hard again. With her, my libido has no limits. Soon, I might be able to have sex with her all day.

“This needs to be taken care of.”

Closing the gap between our knees, she tucked hair behind her ear, like a hostess at an “ejaculation inn.” In her erotic mode, no matter how intense my lust, she never brushed me off, eagerly making me cum.

“Will you suck it?”

Sitting on the tub’s edge, I showed off my erection.

“Can you start with my balls?”

“You like that?”

“W-Well, yeah.”

I’d never had her lick my balls—experience from other girls, mainly Yamamoto-san. Knowing that pleasure might complicate things as lovers.

“If you like it, I’ll do it.”

Gently holding my hips, she kissed my balls, her lips brushing them. The bathroom light highlighted her face’s contours, her flushed lips caressing my dark sack, heightening the thrill of defiling a beautiful girl.

“Feels kinda humiliating.”

She felt it too. Without sucking, she took my balls in her mouth, licking gently before kissing the skin. Her expression wasn’t angry but troubled.

“You feel that even with regular blowjobs?”

“Yeah.”

Unlike Yamamoto-san, she wasn’t naturally servile. Her brother-loving, cum-obsessed mode relished blowjobs, but her core emotions lingered, and ball-licking added a new layer of humiliation.

“But you wanted to use your mouth.”

I only suggested it because she said it was lonely.

“Not saying I dislike it.”

Puffing her cheeks, she took my shaft in her mouth, sucking hard.

“Ooh… M-Miyu…!”

The sudden shift made my hips buck, nearly slipping. Smirking teasingly, she kept sucking, relentlessly pleasuring me. Thrilled to suck again, she didn’t glare to hide her embarrassment, locking eyes as she moved my cock in and out.

“Nn… juru… jururu… juppu…!”

She felt humiliation but craved submission. This sister was way too brother-obsessed.

“Jururu, jupu… chuppu…!”

“M-Miyu…! Go easier…!”

“Nbu… chu… okay, okay.”

Pulling my cock out, she blew air to cool it. Her erotic cuteness made my near-climax penis throb harder.

“Ugh… kuu…!”

“Hey, don’t cum from blowing.”

Scolded, my penis leaked a bit, its red tip barely holding back. The next touch would finish me.

“Looks ready to burst. It can hold off sometimes?”

“It’d soften if I cooled down, but you’re too visually stimulating.”

Her wet, pale, busty lolita body shifted in the water, her soft breasts floating or jiggling as she knelt, stealing my gaze. Her unaware, swollen pink nipples were insanely erotic.

“Keep blowing, and you’ll cum?”

“Definitely.”

“Hmm… that’s kinda cute…”

Nearing my crotch, she stared at my upright cock, pondering for seconds.

“It’d shoot upward without hands, right?”

“If I lean forward, it’ll go more horizontal.”

“Can you do that?”

She was set on making me cum, my scolded penis destined for her breath. Leaning forward, I aimed my tip over her face, risking a facial she’d hate if I missed her mouth.

I wanted her to learn ejaculation isn’t so precise, but she opened her mouth, signaling “cum here.”

“Go ahead and cum, Onii-chan.”

With her permission and open mouth, my conditioned penis twitched, ready to ejaculate without touch.

Scolded and allowed to cum, drinking my semen—my body had learned that as the right way to ejaculate.

She leaned close, blowing “fuu” upward along my shaft’s underside.

“Oh… ah!”

Her breath tickled my sensitive spots. Then, she blew weak, rhythmic puffs at my tip, not forcing climax but gently coaxing, “Come out, I’ll drink it.”

“Ahn.”

Knowing my limit, she opened her mouth, waiting.

“Uuh… ah…!”

Seeing her red tongue in her open mouth, an irresistible urge hit. I shot semen into the air—some hit her lips, but the thickest landed in her mouth. She held it there until I finished.

Even after, she rolled the semen on her tongue before swallowing slowly.

“Nfu. Thanks for the meal.”

Smiling, she savored drinking it again but seemed let down by the thinner taste after repeated ejaculations.

“Too light, not satisfying.”

She’d complain if I saved up, but only thick, gooey semen satisfied her. Once Yamamoto-san’s issue was settled, I’d abstain and let her drink dense semen until my balls ran dry.

“Miyu, uh, sorry, but…”

My penis hadn’t fully released, still hard and sensitive, holding back semen meant for the last ejaculation.

“Gonna cum the rest soon?”

“Probably.”

“Then let’s finish before getting out of the bath.”

Miyu stood, placing her hands on the bathroom wall opposite the shower.

“Put it in.”

Turning her head, her seductive pose was insanely hot.

This sister is so erotic.

“I might cum the moment I enter.”

Wrapping my arm around her waist, aligning my penis, she swayed her hips, rubbing my tip against her slit.

“That’s fine.”

Her cuteness had me half-cumming already.

“Here I go, Miyu.”

In standing doggy, I slid my raw cock into her vagina.

“Ah… so hard.”

Feeling my pre-ejaculation penis inside her, she seemed delighted. Her pure charm gave my lust its final push.

“C-Cumming…!”

Just inserting, barely thrusting, I shot thick spurts inside. She felt it, her expression blissful as I kept cumming.

“So much came out.”

Rubbing her stomach, filled multiple times today, she looked down thoughtfully.

“Maybe one day my stomach will swell just from your semen.”

“It’s not gonna get that manga-level.”

Pulling out, semen floated in the bathwater. No time to soak, so we showered off and left the bathroom. I knew her manga-brain tendencies, but why mention that now?

“There’s this genre, ‘pregnant belly,’ right?”

Wiping her clean body, she dropped a risky term.

“It’s super hot, don’t you think?”

“Y-Yeah.”

Maybe because it evokes pregnancy, it hit her fetish sweet spot. I didn’t ask where she learned it. I’d love to swell her stomach with just my cum—maybe I was an orc in a past life.

“Phew… exhausted.”

Miyu collapsed naked onto the bed. Less than an hour in the hotel, but as she said, we were drained. I’d been made to cum repeatedly—surely she was satisfied?

“Want water.”

At her request, I grabbed free mineral water from the fridge, pouring mine into a glass and handing her the rest. In an open bathrobe, I sipped standing by the table. On the bed, Miyu lay sprawled, naked on a sheet too big for her.

From a distance, it felt surreal. Her glossy, pale, lolita-like body, mature black hair, and firm, heavy breasts. The oddity of sharing a room with such a girl—a dreamlike reality. Knowing this girl on the bed was my sex partner filled me with elusive joy.

“Onii-chan.”

She gazed at me, barely covered by the sheet, a stunning girl nearing the peak of feminine beauty.

“What’s up, Miyu?”

But to me, she was just my sister. Today’s date only solidified that. I could only love her as a sister.

“Wondering how your sister feels in a love hotel.”

She understood what men find erotic. Calling me from a hotel bed as my sister carried a lascivious tone.

“Why are you so sexy, Miyu?”

I climbed onto the bed from the foot, approaching her.

“My big breasts?”

“Not that simple…”

Her tilted head flashed her ample chest from the sheet’s edge, making my penis twitch—maybe not entirely wrong.

With her, I’m endlessly aroused. Seriously, isn’t this dangerous? Like some kind of lust overload.

“Still up for cumming?”

“Starting to feel like it again.”

“Impressive, Onii-chan.”

Holding the sheet, she touched my softened penis with her other hand.

“Your siscon level.”

“That’s the part?”

True, I’m crazy about my sister. I’m a lolicon and siscon, no denying it. And Miyu, teasing me, loves being adored by her siscon brother—a true brocon.

“Being full of love for your sister is great.”

She stroked my penis, swelling with each twitch. Her arm reached further, brushing from my balls to my sensitive rear. Her fingers on untouched skin hardened my cock fast, and she watched with a knowing smile.

“What’s up, Miyu?”

“Nothing~”

She shook her head, dodging. What to do with this erection? I could pull off the sheet and demand sex, but the mood wasn’t quite right.

“Can I cum in your mouth?”

Kneeling, I asked as she sat up on the bed.

“Want a blowjob like this?”

“That’d make me happy.”

Shedding my bathrobe, I brought my erect cock to her mouth. Exposing myself still felt odd, but knowing she’d comply mixed embarrassment with excitement.

I hoped she’d get there someday. We’d done most things, but cunnilingus was a hard no. If she ever asked me to lick her, it’d be insanely hot.

“Onii-chan.”

She licked just under my tip.

“Oh… ooh…!”

“Hehe.”

Smiling at my involuntary moan, she asked, “You want your sister’s mouth to make you cum, right?”

“That’s what I meant.”

Was she adding conditions now?

“On the way, there was that ‘Sister Paradise’ salon, right?”

I recalled how she fixated on it.

“How much does a place like that cost?”

“Hmm… it’s like a pink salon, right? Maybe seven thousand yen for a forty-minute blowjob.”

Suzuhara once rambled about adult services, so I had some knowledge.

“So, say it’s ten thousand yen for an hour. At Sister Paradise, a guy gets a blowjob from a pretend sister, right?”

“Yeah.”

This random sex shop talk. My cock was still out, and she ignored it, looking up at me.

Silence followed. Then, she suddenly took my tip in her mouth, sucking hard.

“Ugh, ooh… what’s that, M-Miyu… uah… ah…!”

Starting abruptly, she rolled her tongue around my cock, staring at me. After a loud suck, she popped off.

“Feel good, Onii-chan?”

Her sudden question startled me.

“O-Of course.”

Still staring, she took me in again, sucking slowly.

“Ah… so erotic… ugh… feels good…!”

Her odd behavior puzzled me, but it was insanely hot. Despite countless blowjobs, this felt uniquely erotic.

“Juru… nchu… jururu… chupa… n, buha… hehe, how’s that, Onii-chan?”

Her voice was oddly sweet, almost seductive.

“No words, it’s crazy erotic…”

I realized why her sexiness spiked.

“You love blowjobs the most, right?”

Dropping the sheet, she held my cock’s base with both hands, resuming.

“Hamu… chu… Onii-chan… juru… nchu… puha… nn… chubu…”

As siblings, her calling me “Onii-chan” was natural, its lewd undertone overlooked. The depravity of her knowing my love for blowjobs, built from our repeated sex, hit hard.

“Nn… juru… jupu… hero… chupu…”

“M-Miyu…!”

Having my real sister suck my cock—stripping our acts to that context, we were doing something outrageously erotic.

“Gonna cum, Onii-chan?”

Her higher-pitched voice, lips still on me, sent her breath from tip to hips.

“Cumming, cumming…!”

Her question, more than the oral, triggered me. I thrust into her mouth, releasing freely like relieving an urge.

“Nku… nn… more semen, Onii-chan. Barely any taste, but it’s still thick.”

Swallowing, she toyed with my still-hard cock, not letting go. My orgasm was less ejaculation, more like a girl’s climax.

“Hey, Onii-chan.”

“What?”

Her next words caught me off guard, stirring a mix of anticipation and curiosity about what she’d say or do next.

Miyu looked up at me with moist eyes.

“You can still cum, right?”

Her calm voice carried lingering expectations.

“If you say so, I probably can…”

“That’s my Onii-chan.”

Beaming at my response, she continued the blowjob.

I thrust my hips forward, entrusting my penis to her whims.

“Nn… nchu… mutchu… juru…”

From then on, she was relentless. No lewd words or wild thrashing—just pure love for sucking my cock. Thrilled to finally focus on it, she devoured my shaft mercilessly, using her throat, cheeks, and tongue’s underside to savor every inch.

“Guh…!”

I didn’t want to interrupt her immersion. But the urge to cum was unstoppable. Her tongue, licking from tip to base, overwhelmed me, my balls tightening upward.

Grabbing her shoulders to shift her tongue from my sensitive spots, I couldn’t escape the pleasure. At my absolute limit, I came in her mouth without warning.

“Nmu… juru… jurujupu… zuju… juppu…!”

“Guaah… ah…!”

Even as I ejaculated, she didn’t stop. Instead of swallowing, she smeared my semen on my cock, sucking it clean with one intense pull.

The overwhelming sensation buckled my knees, making me fall back. She chased me, still sucking as I lay on the bed. Now on all fours, she bobbed over my cock.

“Chu… chupu… juru… kuchu…”

Her movements weren’t aggressive—just focused on sucking. Not a forced blowjob to make me cum endlessly, but a slow savoring. Her tongue writhed to finish me, but she was tasting me thoroughly. She’d brushed it off, but not giving blowjobs lately must’ve frustrated her deeply.

“Juru… ju… jururu… nn… guchu…”

I stared at the ceiling, letting my sister lick my privates. More accurately, I was indulging her desire to suck me off in this love hotel.

Her passion kept me hard despite multiple ejaculations. She forced my erection, and I lay there to let her blow me.

She seemed to enjoy my unannounced cumming. When the next wave hit, I ejaculated in her mouth without a word. She licked, swallowed, and sucked until my balls were drained.

I lay there, cumming in her mouth five times. Only when my lower abdomen went numb and my penis softened did she finally release it.

“Nn… puha. Thanks for the meal, Onii-chan.”

Politely thanking me, she lay beside my exhausted body. Drinking her brother’s semen, she looked fulfilled.

“How was getting off so much while lying down?”

“Pure bliss, the best.”

Being pleasured without effort, free to cum without restraint, was liberating.

“You satisfied, Miyu?”

“Yup, super satisfied. If you’re up for it, I wanna do this again.”

She loved this play—sucking me off without worrying about me, making me cum repeatedly. It suited us perfectly.

“Miyu.”

“Hm? What?”

I stroked her glossy hair, its black strands striking against her pale body.

“Today’s date made me love you even more.”

The lack of “girlfriend vibes” remained unresolved, even fading since our spa sex. Instead, I saw her more as a sister, doubling my love for her.

“I feel it too. It’s made me a bit more honest.”

She hid her blushing cheeks.

“Which Miyu is this?”

She’d said her instinct-driven mode persisted since the spa, but her vibe and actions felt closer to her neutral self.

“You probably sense it.”

After glancing away, she shrank slightly, meeting my eyes.

“My core self is starting to overtake my instincts…”

That was her shyly shared secret. Surpassing her instincts didn’t mean her rational side controlled her lust—it meant her true feelings were outgrowing her raw desire.

“So…”

Cutting off my thoughts, she continued.

“I’ve used my instincts as an excuse, but I’d love if you’d go along with whoever I am in the moment.”

She seemed conflicted about balancing her sides, but I loved both Miyus and nodded without hesitation. Her intense sexual instincts for her brother were undeniable, making her wildly erotic or rational by turns—something I’d grown used to.

My only concern was the recurring thought: with her instinct mode, I felt some girlfriend vibes during our intimate moments. Feeling lover-like only through sex seemed questionable, but loving neutral Miyu as a sister felt right. It’d come down to aligning with her wishes.

“By the way, why bring up Sister Paradise?”

“I wanted you to know lots of people fantasize about a sexy sister.”

“Got it.”

As an eroge fan, I understood. Sister-themed content is a huge genre. Few lust after real sisters, but many imagine erotic, anime-like ones.

“Good thing my sister’s sexy.”

She’d resisted admitting it, but she was finally embracing her erotic side.

“Your sister’s glad you’re into 2D girls.”

Smirking, she noted that without my 2D love, I wouldn’t get her love-doll fetish. Being an eroge otaku paid off.

“Onii-chan.”

Stretching, she bared her soft body, hugging me briefly.

“I’m thinking about our future too.”

After graduation, what jobs we’d have, what apartment we’d share, how we’d live—as siblings and lovers, we needed to plan. First, which university tier to aim for.

“First, we gotta plan sex frequency. Kanade’s sharing the load now, but when she’s gone, it’s all me.”

“Exactly.”

Overwhelming lust or getting too hooked on Miyu—both tricky. It’s our top priority; university’s secondary.

“For living together, noise means a condo, not a house like now.”

“You’re loud too, Onii-chan.”

“Not as loud as you.”

“Mmph.”

“Sorry.”

We’d need quieter sex methods. Planning this was fun—our future felt bright, making any worry enjoyable.

“Hotel’s got time, but wanna sleep?”

“You?”

“Honestly, home’s fine now.”

“Right. Nothing beats your sister in a love hotel.”

My sister gets guys perfectly.

“Let’s head back.”

After an hour of burning off lust like fleeting lovers, we left. I secretly hoped to bring her back in her school uniform before graduation, keeping that desire tucked away.
