My Little Sister Is the Best F*p Material - Volume 7 Chapter 02: The Gentle Drizzle of Rain

Volume 7 Chapter 02: The Gentle Drizzle of Rain

Outside of sex with Miyu, I’ve been holed up in my room, and my school homework is nearly done. Now that we’re lovers, I feel we should spend more time together, but keeping some distance seems right for us. We’ve always lived on our own terms, so being together only when needed feels natural.

Plus, Miyu gets it. A guy’s love is tied to lust, inseparable. Both giving and craving need just the right amount, and staying a wall apart makes the desire and affection stronger.

(Still some time before noon.)

I closed my school workbook and spread out my exam prep book. Lately, reading problems feels less daunting, and I’m making good progress. Not to toot my own horn, but as Miyu’s brother, my brain’s not half bad. Still, like how games require a separate knack, studying efficiently needs a trained “study brain,” and I’m paying the price for slacking off before.

Luckily, I’ve got a lifeline. Yamamoto-san suggested a study session. She remembered me buying study supplies at the department store.

It’s obvious this “study session” is a pretext for sex, but if I can study and advance Miyu’s plan, it’s a win-win, so no reason to refuse. I replied I’d consider it positively and focused on studying for the morning. At lunch, I’ll ask Miyu about our plans. Nothing takes priority over a date with her, after all.

I highlighted my book clumsily, finished a good chunk, then put away my study materials and left my room. Knocking on Miyu’s door got no response—she must already be downstairs, cooking. In the living room, I found her in the kitchen, packing marinated meat and soup into freezer containers, chopping and mixing leftover vegetables into separate packs.

“Nice work studying.”

Noticing me, Miyu offered words of encouragement. We slept together last night, so she knew I’d been studying since morning. She was super groggy today, taking twenty minutes to peel off me.

“Homework’s done.”

I answered, looking at Miyu, her hair tied in twin tails. With her thick hair, splitting it makes it easier to tie.

“That’s great.”

She said, “Now you can use the rest of the time for other things,” her lips curling slightly as she continued prepping. Other things—exam prep, the reconciliation plan, or sex with her? Regardless, Miyu in an apron, cooking diligently, was dazzlingly cute.

“You’re using ingredients outside the menu.”

“Thanks to my lustful Onii-chan, menus have lost all meaning.”

Finishing with the vegetables, Miyu washed the knife, wiped it dry, and stored it. With sex more than twice a day, often crashing right after, we’ve been skipping meals, leaving fridge contents to pile up.

So, she’s switching to meal prepping, eating as needed. She’s also taken on more cooking to let me focus on exam prep. She’s the one taking entrance exams, but since she plans to attend my high school, she doesn’t need to study.

“Too much?”

“Oh, absolutely. Going wild with your sister, Onii-san.”

When I stood right behind her, the top of her head reached below my collarbone. Her glossy hair cascaded down, framing a small, doll-like face, below which her perky, well-developed chest blocked my view.

How can she be so slim? Since we started having sex, she’s even gotten plumper. Her sexually mature body makes plain clothes and an apron oddly fetishistic. If this erotic, concentrated sister were a clingy, purring girl… no, her usual coolness is exactly what fuels these desires.

Even as I indulged in wicked fantasies or touched her, Miyu kept wiping down the cleaned kitchen tools, unfazed. Her aloof yet loving charm is unique.

“You look especially e… apron-y today, Miyu.”

My impure thoughts almost made me say “erotic.” I meant to call her cute.

“Just an apron looks that good?”

She pinched the apron with both hands, looking up at me.

“It’s because it’s just an apron.”

Nowadays, aprons scream “naked apron,” but I find her wearing one over regular clothes cuter and more arousing. Before, Miyu wore clothes that hid her chest, but the apron’s tie now accentuates her curves. How could it not be erotic?

“Sounds like you’re turned on by my breasts.”

“More like, I’m turned on by your breasts too.”

With a sister like her, I can’t help but get hard. I’m practically forced to be erect around her daily.

“Um, Onii-chan?”

“Look, we haven’t done it yet today, right?”

Pressing my erect penis against her clothed body brings a different kind of thrill and pleasure than sex. That’s just how male lust works.

“I made those for tomorrow onward. I’m about to cook lunch now.”

“So I thought it’s perfect timing.”

The kitchen counter’s all cleaned up too.

“When I have sex with Onii-chan, I get weirdly full.”

“Should we avoid it before or after meals then?”

“No, it’s fine. Satisfying my brother’s lust is a sister’s duty.”

Miyu, despite her words, seemed into it. She had me step back, making just enough space to brace her hands on the kitchen counter. Then, she slipped both hands under her skirt, pulled her panties down, and hiked up the back of her skirt, revealing the plump curve of her buttocks at the base of her thighs.

“Here you go.”

That was all the prep needed for sex. No foreplay, minimal undressing, and an invitation as blunt as it gets. Faced with her exposed entrance, I was flustered like a naive boy.

“Just put it in…?”

“That’s what the hole’s for.”

Fair enough, but still.

“You’ve got a condom, right?”

“I do.”

These past few days, I’ve been getting aroused outside the bedroom, so I carry condoms everywhere. Miyu’s orders to not ruin the mood.

“Then put it on quick.”

“Y-Yeah.”

I followed her urging and put on the condom. I’m hard, and I want sex, but…

“Hey, I’ve been wondering. Don’t you need foreplay?”

“I get wet just from being close to Onii-chan.”

“I know you get wet easily, but…”

Foreplay isn’t just to ease insertion pain. It builds anticipation for sex, and some people enjoy oral as much as the main act. It’s also a chance to show off a guy’s skills.

“Wouldn’t it be nice to have a little time for fingering?”

“Ugh… but you touch me weirdly…”

“I won’t.”

Miyu’s shy, but from our past interactions, I know she’s not entirely against it.

“You said I’m good at fingering, didn’t you?”

“I wasn’t lying. But I’ve never once begged for it.”

True, she’s never explicitly asked. Her attitude has hinted at it, but she’s never said it outright, and she’s fiercely rejected oral.

“Then, since I want to, can you let me finger you a bit?”

“Fine… just a little, okay?”

Miyu relented with a resigned look. We’ve always gone straight to insertion, but if she gets used to being touched, she’ll want foreplay eventually.

Believing that, I slipped my hand under her skirt, grazing her lower abdomen to her crotch. She leaned forward slightly, her twin-tied hair sliding off her back.

“Nn…”

Her reaction wasn’t bad. Her hairless labia, soft and plump, formed a gentle mound under my fingers. I slid two fingers along the sides of her slit, heightening her sensitivity.

“Ah… nnah… I said… not there… n-no…!”

The springy flesh bounced back as I pressed my fingertips, irresistible. Her entrance, true to her cool personality, was tightly sealed, but once I slipped a finger in, hot, viscous fluid oozed out like a broken egg yolk.

“Nya… ahn… I said no…! You’re touching me like that…!”

Miyu clamped her thighs shut, so I stopped my fingers, still holding her waist. She glared at me, embarrassed.

“Picking at my insecurities…!”

She’s self-conscious about her childish-looking privates—I knew that. But her past refusal of caresses was mainly because she hated being seen in pleasure one-sidedly.

She’s gotten used to me seeing her aroused, so maybe her remaining insecurity feels bigger now. If so, I should turn that complex into something she can be proud of—or at least not a flaw.

“Miyu, listen. Big breasts and a ‘smooth, plump’ down there? That’s a guy’s dream.”

It’s not just about being hairless or youthful. A mature girl like Miyu with a smooth, puffy slit on snowy skin is perfect.

“If it’s ‘smooth, plump’ down there, it should be ‘smooth, flat’ up top for girls.”

Our kinks didn’t align. This seems like a deeper mismatch than words can bridge. Pushing further might be risky.

But I can’t give up on fingering. I’m certain this reluctance is within her usual “I don’t care as much as I say” range.

“Hey, Miyu. That adorable, smooth, plump part you don’t want anyone—especially guys—to see or touch…”

“‘Adorable’ is unnecessary. And don’t emphasize ‘smooth, plump’ about my privates. I know them best.”

Sorry about that.

“If you let me be the only one to touch that part you hide from everyone… wouldn’t that make our relationship feel even more special?”

“It’s already special enough…”

Miyu looked unconvinced, but the vise-like grip of her thighs on my hand loosened.

“I thought having real sex with Onii-chan would make me feel more grown-up.”

“It’s stayed shockingly smooth and tight.”

Even with daily sex, her vagina’s tightness hasn’t changed.

“Thinking I’ll live with this peach-like crotch forever feels heavy.”

“I’m the only one seeing it outside a hot spring.”

“Well, yeah.”

The air between me and Miyu softened. This might be my chance.

“Alright, let’s continue.”

“Eh, w-wait… I haven’t exactly agreed… nnah…!”

I slid my fingers back to her crotch, stretching to stroke her fully when pushing in, curling to tease her clit when pulling back.

“Ah… ah… n-no… Onii-chan… that’s… no good…!”

Miyu’s moans were softer than before. She was aware of the pleasure creeping in, desperately trying to suppress it. But as I traced the entrance with my fingertips, she couldn’t hold back, letting out a sharp exhale.

“Yah… hiyah… stop… don’t touch so much…!”

She wriggled her hips to shake me off, but my firm grip from behind held strong. When I bent my second knuckle to stir her shallowly, pleasure overpowered resistance, her struggles weakened, and I caressed her pristine crotch with all four fingers.

“Nn… ah… hey, stop it…!”

“Miyu… please… I can’t be satisfied without this smooth, plump part…!”

“N-no, ah! Onii-chan… you’re so gross…!!”

Her words rejected me, but her hips, once dodging, now rocked back and forth. For such an honest sister, I positioned my middle finger upward, pressing its tip to her entrance. As she thrust her hips forward, my finger slipped fully into her vagina with a slick sound.

“Aaah—ngh…!!”

Grabbing the kitchen counter tightly, Miyu stood on tiptoes, reaching orgasm. She froze for a moment, then lowered her heels as the throbbing subsided, glaring at me with teary eyes.

“Ugh… you perverted lolicon…”

To be so despised by my sister just for foreplay.

“I’m mad now.”

Puffing her cheeks, Miyu marched to the fridge, grabbed the kitchen timer stuck to it with a magnet, and returned. She reset it, pressed the ‘one minute’ button once, and set it on the counter.

“Come before the timer.”

“That’s way too short!”

“It’s enough. You’re a quick shot anyway.”

That stings more than you’d think.

“Come on, hurry up and put it in.”

Miyu turned her butt toward me, inviting me with zero sentiment. Frustratingly, despite all her scolding, my penis stayed hard, ready to slide in.

“No going deep, right?”

“Obviously. Three centimeters below the glans—that’s the limit. Stick to it. I’ll know.”

She whipped one of her twin tails like a lash, glaring sharply. Is she a hall monitor now, dictating how much penis I can insert? She seems less resistant to clothed sex lately—maybe if I asked, she’d do it in her uniform.

Despite her bravado, she’s as weak to her erogenous zones as I am, destined to melt in two panels flat. Still, she clings to her pride, insisting her true self isn’t drowning in sexual pleasure, refusing to show desire.

She’ll just blame her instincts when she falls anyway. I almost pity horny-mode Miyu.

“What’re you spacing out for?”

“I got it. I’m putting it in.”

I lifted her skirt, gazing at her exposed butt. Her panties, hanging at her thighs, could drop to the floor or stay—tough call. Sex is about the hole’s angle and the penis’s alignment, and standing doggy needs her legs spread for proper insertion.

But since I’m only allowed half in, maybe I’ll lift her slightly and slide in. For a sister who wants to be used for my sexual relief, rough thrusting should satisfy her.

Miyu stared out the window, trying to stay detached, determined not to crumble easily after her bold stance. I leaned over her from behind, wrapped my hands around her waist, lifted her just enough to stand on tiptoes, pressed the timer’s start button, and thrust my penis in.

“Ugh… kuh…!”

Her slit, which closes tight after light fingering, held a dam of love juices. As my glans breached it, air bubbles gurgled, and Miyu, stone-faced, faintly blushed.

Per her orders, I stroked only half my penis’s depth, keeping a steady pace so she wouldn’t feel its shape too vividly. Her vagina, made for sex with me, fit my glans perfectly to her sensitive spots, squeezing the shaft tightly even without going deep. This dog-like mating from behind stirred my primal instincts, making it easy to come.

Frustratingly, one minute was enough to ejaculate. But it’s time to show some brotherly dignity—no more pathetic quick finishes. I thrust mindlessly to delay coming. Thirty seconds in:

“Fu… ah… fuu… nn, nnh… ah…!”

Glancing at Miyu’s profile, her expression was slack, melting with pleasure. She gripped the counter, back straight, projecting defiance, but her mind was likely flooded with lewd, pleasure-soaked words.

Even in that state, she focused on the timer. As love juices splashed with each stroke, she checked the sixty-second countdown. Each glance showed longing beneath her ecstasy—she must regret setting a time limit.

“I’m about to come, Miyu. Is it really okay to finish this fast…?”

I teased Miyu from behind, testing her. She quickly masked her softened expression, forcing a defiant glare.

“O-Obviously… nn, ahh, I… have to… make lunch… ah… ngh… haa…!”

Her suppressed moans slipped out with each breath. What a devoted sister, still thinking of cooking for me in this state.

“Nn… it’s almost a minute… ah, aah, nn, ah… hurry up and finish…!”

Ten seconds left before time’s up. But her order was to “come before the timer.” I agree a minute’s enough, but I never promised to finish within a minute.

“You just said to come before the timer, right?”

I reached for the timer and hit pause. Now I can rub my penis in her flesh as long as I want.

“Ah, w-wait, that’s cheating… sly… nyah, aahn…!”

Taking advantage of her brief relief, I sped up my thrusts.

“An, ah… aah… nnah…! Onii-chan, that’s mean… nn, aah… I’ll get mad if you do that…!”

Despite her angry words, her voice betrayed her pleasure. Even her sidelong glare shimmered with lustful affection.

“You look like you’re enjoying it, even if you’re mad.”

A slightly deeper thrust drew a higher-pitched, strained moan. Even for Miyu, who craves being claimed, just being used freely isn’t enough—she accepts things against her will because they’re reasoned. So, since I justified pausing the timer, I can keep thrusting into her as much as I want.

“An, ah… it feels good, but… ngh… fuah… that’s… separate… nn, aah…!”

Her lower mouth, pierced by my shaft, pulsed like it was giving a blowjob. My nerves focused on the glans, each stroke amplifying the pleasure coursing through my groin.

“Damn, I really can’t hold back anymore…”

“Ahn… ah… don’t hold back… come right now…!!”

Her stern command, delivered with teary eyes and a lifted chin, set my body ablaze. It was the first time she’d ordered me to come so forcefully. My chest surged with an excitement akin to a racing heart. My penis throbbed wildly in her vagina, my body surrendering faster than my mind.

“M-Miyu… I’m coming… Miyu… Miyu!!”

Ejaculation hit in an instant. Keeping my penis shallow, I spurted inside her, slowing my thrusts as the climax faded. Perhaps because I was moving, she didn’t notice the exact moment—unusually, Miyu didn’t climax with me. When I pulled out, she slumped over the kitchen counter, exhausted.

Releasing her waist, I saw her legs, barely supported on tiptoes, trembling from muscle fatigue. While I tied the condom and tossed it, Miyu steadied her breathing, slowly pulling her panties up with one hand.

“I… need to make lunch…”

Right after sex, Miyu got to cooking. Her apron hid her slightly bowed legs as she shuffled across the kitchen. She could rest if she’s tired, but she stubbornly refused my help, so I lounged on the sofa, idly scrolling my phone.

Without much talk, Miyu set out the food, and we ate lunch as usual.

“Was there a reason you pushed to cook?”

I asked, noticing her obvious attitude. By the time the food was ready, her breathing had normalized, and aside from minding her crotch while sitting, she seemed back to normal.

“I think sex for cuddling and sex for relief are different. For relief, I want it quick and done.”

“I see.”

She doesn’t want to drown in pleasure during relief sex, and ending up too exhausted to cook isn’t her goal. I don’t mind sex just for release either, and for us siblings, who can’t get too deep, quick sex might be a daily necessity.

“Doesn’t that leave you frustrated?”

“You’re still naive, Onii-chan. Can’t be helped since you’re a sex newbie.”

Miyu, with her female-only experience, spoke condescendingly. How am I a newbie with my fair share of partners? I’ve done semi-public play, breastfeeding, cosplay sex, and more. She just said, “Imagine the future specifically, and you’ll get it,” then finished eating and returned to her room.

I didn’t study, just flopped back on the sofa. If we keep avoiding dates until the rain stops, summer break will end. To make memories with Miyu, we should go out, even if it’s forced. But most big events like fireworks ended in early August, and online searches only turned up hot spring travel specials. A train trip to a scenic spot with Miyu could be fun, though.

I lounged on the sofa, staring at the ceiling, mulling over future plans.

(Come to think of it… Miyu said it’s almost that time…)

The so-called “girl’s day,” the mysterious phenomenon of menstruation, shrouded in secrecy for guys like me. All we need to know is it messes with hormones, causes discomfort, and puts sex on hold for a few days. But once her period ends, Miyu and I can have raw sex.

That means I’ll be able to come inside her. Despite seeing it countless times in porn or hentai, the reality feels unreal. When Miyu said, “Imagine the future,” she probably meant our relationship after creampies. But can creampies and quick, detached sex really mesh erotically?

In eroge and hentai, creampie sex is depicted as intense, romantic, or even forceful, but always significant. Ejaculating inside a girl’s vagina carries a special weight.

Using creampies just for sexual relief, detached from the act of sex, feels less like treating her as a sex toy and more like a mechanical semen dump. But… maybe that’s erotic in its own way.

If I creampie her, the semen left in her vagina might drip into her panties, reminding her of sex every time she uses the bathroom. With her libido, could she resist getting aroused? Miyu’s unique in several ways, but her love for masturbation is rare for a girl. Even Yamamoto-san said she barely did it before meeting me.

Is she doing it in her room right now? That half-finished sex probably left her frustrated. She wears simple T-shirts around me, but maybe she puts on cute clothes when she’s alone.

Oh, I forgot to ask about her schedule for Yamamoto-san’s study session. Would she be mad if I went to her room now? To check if she’s masturbating, I’d need to listen closely or knock. Is it eavesdropping to secretly hear your live-in lover’s masturbation? Rubbing genitals together, masturbating face-to-face, or secretly getting off to each other—it’s all similar in a romantic relationship. So, checking discreetly should be fine.

With that flimsy justification, I headed upstairs. Miyu’s friends have warped my morals, but no point regretting it now. Two doors greeted me: mine in front, Miyu’s further back. This house isn’t old, but it has a fatal flaw for kids—no locks on bedroom doors. A nightmare for teens discovering masturbation. Still, I played eroge boldly, assuming Miyu would never barge in.

Tiptoeing to her door, I heard no moans. The first time I caught her masturbating, she thought I’d be out late from work, so she was brazen. With me home and likely to come upstairs, she’s probably too cautious to make noise.

(Assuming she’s masturbating is rude to begin with.)

I exhaled my wicked thoughts and knocked.

“Miyu, you free?”

No response after ten, twenty seconds. She should be in there—she’s not in my room. I checked mine, but it was empty, no signs of use. Maybe I caught her mid-masturbation, and she couldn’t answer right away. Then, the sound of her doorknob turning and the heavy creak of her door opening.

“Were you busy?”

Miyu cracked the door a few centimeters, tilting her face so only her eyes showed. If she was naked, she’d need just seconds to dress. This must be the “wearing embarrassing clothes” scenario.

“As you can see.”

She answered awkwardly, frowning. She’s saying she can’t show what she’s wearing.

“Sorry.”

“What’s up?”

“Wanted to check your near-term schedule.”

“Prioritize Kanade-san’s schedule.”

She understood my intent perfectly.

“Got it.”

After that brief exchange, I felt a slight unease—she hadn’t shown more than her eyes. Normally, she’d at least show her face.

“You’re dressed, right?”

“Yeah.”

“Something new?”

“New… more like a costume to sell my soul.”

“Oh?”

So this is her final debt to Haruka. She answered calmly, but behind the door might be some outrageously erotic outfit.

“The clothes themselves aren’t sexy.”

“Then why hide?”

I’ve seen plenty of her lolita cosplay and thought I’d been understanding.

“It’s hard to explain… but oh well.”

Miyu opened the door, revealing her outfit. She wore a black pinstripe blouse, neatly styled as lolita fashion. But what stood out were the two triangular peaks atop her twin tails and the long, sleek tail extending from her hips. Cat-ear fashion—a fetish staple.

“Miyu… why this…?”

It’s a common costume, but seeing Miyu in it shocked me. Cat ears didn’t seem to fit her tastes or principles.

“Come in, come in.”

She invited me into her room.

“Is that okay? Weren’t you busy…?”

“It’s fine. I was just inspecting it, wondering how to explain it to you.”

She sat me at her desk chair and took the bed. She moved cautiously, bending her knees and sitting carefully. Is that tail that kind of mechanism?

“I’m helping with Haruka’s job just once. This is the outfit they provided.”

“A whole outfit for one job?”

“Secondhand doesn’t always get cheaper. Especially for Haruka.”

Sounds like shady agency work. I don’t know the details, but still.

“But why cat ears?”

“Haruka’s taste. You only know the clothes I pick, but there’s a wider variety. Haruka and I have similar yet opposite tastes in lolita fashion.”

According to Miyu, for Haruka, who engages in lolita fashion both as a hobby and a business, as long as the result is a cute lolita look, either the girl or the clothes can be non-lolita. That’s why Haruka gets excited seeing Yamamoto-san, loves big breasts, and wants to dress Miyu, the lolita with big breasts, in anything.

“In other words, Haruka’s taste is ‘lolita or lolita.’ But I’m the opposite—I want both the clothes and the person to be lolita. Call it ‘lolita and lolita.’ We’ve kept that boundary sacred until now.”

“That different, huh?”

“Completely.”

Miyu continued, somehow folding her fake ears and swishing her tail. Haruka prioritizes her own pleasure, not chasing pure girlishness despite loving lolita, and has no issue using tools like dildos despite claiming to be lesbian. She blends hobby and business, picking what suits her. Miyu, however, embraces lolita as both a modern symbol of youthful innocence and a fashion, a matter of taste and principle.

“So, by bending your principles to help Haruka’s job, she’ll be satisfied?”

“I won’t answer details, but yes.”

“Why are you wearing it now?”

“For sizing. And, well…”

It’s still cute, isn’t it? she mumbled shyly, revealing her true feelings. Despite her convictions, Miyu struggles to resist her own sexual allure, separating rational choices from instinctual ones.

“Any chance you’d let me buy it for sexy times?”

“Absolutely not.”

Figured it’d be tough. But since she owns similar outfits, if I just get ears and a tail, we could recreate it, right?

“No means no.”

She shut me down hard.

“By the way, is that tail… in?”

“If you’re asking if it’s in, it’s in.”

Her answer implied it might not have been until I asked.

“So I did interrupt something.”

“It’s fine. My period’s close, so I wasn’t planning to do anything in this. Just getting in the mood, then going with the flow.”

“I see.”

So that’s what she meant by “just inspecting.” She’s gotten better at expressing her feelings, probably because she’s a bit pent-up.

“Speaking of, this might not be something to ask outright…”

Her mention of her period sparked a question. I’m pretty lustful, and part of why Miyu’s with me is her love for sex with me. So, I felt I should ask.

“When you’re on your period, should I handle things myself?”

Most girls feel unwell during it, and undressing for sex is practically impossible due to discharge. But periods don’t erase a girl’s libido. For Miyu, it’d be a dry spell, so going solo might not be ideal.

“Hmm…”

Sitting primly on the bed, blinking her big eyes, twitching her cat ears, Miyu thought for a bit.

“Don’t worry about my condition. Use whatever part of me you can.”

That was the answer from my sister in a fancy lolita outfit with cat ears.

“No one’s as okay with being used as you, Miyu.”

“The sisters in your sex games were like convenient home brothels. Maybe my body’s drawn to that.”

No way.

“Even so, it feels right for who I am. I can’t serve full-on every day like Kanade-san.”

Her words made sense, even if I didn’t fully get it. Whether Miyu or Yamamoto-san was my girlfriend, they’d both let me get off when I need. But Yamamoto-san, proud of being a sexy girl, actively indulges me, while Miyu, reluctant to admit her own sexiness, still lets me use her anytime. That difference is key to why “doing it with Miyu” excites me, and living as someone who naturally turns me on suits her.

“About Yamamoto-san, she invited me to study together.”

“She’s probably pent-up after a few days without.”

Yeah, figures.

“Tomorrow work?”

Miyu offered her opinion casually. Her confidence must come from certainty of success. With the endless rain keeping Yamamoto-san home, she probably wouldn’t mind a sudden invite.

“There’s some kind of trump card to flip things with Yamamoto-san, right?”

Miyu won’t spill the full plan to keep me from meddling, but the better I get along with Yamamoto-san, the smoother things go. That means there’s a pivotal moment where she’ll have to give up on me.

“No trump card.”

Miyu tilted her head, her tail drooping limply. How does that tail not stimulate her sensitive spots? Anyway, no trump card?

“No need for a flip.”

“But at this rate, I’ll end up with Yamamoto-san…”

“That’s where you’re wrong. You’re steadily, step by step, heading toward a peaceful breakup. Just keep moving forward, grounded.”

“No way.”

How can Yamamoto-san and I, so couple-like, just part ways without some big event? If her plan was that letting me touch her freely would eventually satisfy her, it’s backfiring—she’s only getting more attached.

But I was fundamentally mistaken. Thinking our bond is growing comes from only seeing Yamamoto-san when we’re together. While I’m casually talking with Miyu, Yamamoto-san is living her own life, experiencing things I don’t know, thinking thoughts I can’t guess.

“That’s what the letter was for.”

Miyu spoke coolly, neither sad nor mocking, staring out at the drizzling rain, her tail swaying.
